Title: Emergency response drills

Description:
FIELD 
     Embodiments of this disclosure generally relate to communication systems, and, in certain embodiments, to a communication system integration and operation. 
     BACKGROUND 
     Communication systems facilitate communication of status and events within some defined area. Communication systems also allow organizations and facilities to coordinate activities within said facilities. For instance, one particular type of communication system is an intercom system within a school campus. The school intercom system communicates status and events within a school campus to students, teachers, other staff members, visitors, and so on. In this manner, those within the school can maintain a daily schedule for the school and be able to receive specific information via the announcements. Typically, the intercom system allows for audio communication, which can be effective in alerting individuals within the school of status information, but its effectiveness can be beholden to the performance of its user. For example, effectively communicating important information during stages of a practice drill or an emergency is dependent on the specific user using the intercom system.

     While the disclosure will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the disclosure. 
     DETAILED DESCRIPTION 
     Embodiments of the disclosure described below are directed to communication systems that facilitate schools to practice emergency situations and report on successes or failures of such practices. Examples of emergencies include earthquakes, tornados, active shooter situations, and so on. For instance, embodiments of the disclosure describe communication systems with critical functionality such as providing detailed steps and procedures to follow during a practice emergency situation. 
     The embodiments of the communication system described below are directed to improvements on a manual intercom/walky-talky system typically found within a school environment. However, the communication system that is the subject of the disclosure contained herein is not intended to be limited to use within a school environment. Indeed, embodiments of the communication system, may be utilized in any environment that includes multiple rooms, spaces and/or hallways, such as found in office buildings, military bases or other similar structures. As such, the disclosure describing the functionality of the communication system described below are not limited strictly to the school environment. Rather, the description is provided in relation to the school environment for ease of description, and could be extrapolated to other environments, as would be understood by one of skill in the art in view of the disclosure contained herein. 
     Embodiments of the disclosure provide an emergency drills system that conducts emergency drill practice in a structured organized way. Embodiments of the disclosure provide a repeatable structured way to initiate and conduct a drill, instead of manually alerting a school for emergency drills. Embodiments of the disclosure provide an ability to exclude individual steps from the practice emergency drill that would normally be performed during a real emergency. For example, during the practice drill, reaching out to law enforcement is not necessary since an emergency is not present. Therefore, the emergency drills system can exclude steps such as dialing 911 to reach law enforcement during the practice drill. In some embodiments, the emergency drills system also creates or generates reports for a performed practice drill, providing proof that the drill was performed and providing statistics surrounding the drill, thus allowing a school system to demonstrate compliance. 
     With respect to the school environment, individual schools may be arranged into school districts based on a geographic proximity between each school. Further, each school may include communication equipment that allows for communication of a school schedule and for communication between locations within the school and the district. This communication equipment generally includes devices such as classroom speakers for direct communication between a classroom and a front office of the school. Typically, the communication equipment within each individual school is interconnected district wide. Emergency drills that schools may practice include gas leaks, bomb scare, shelter in place, HAZMAT, tornado, active shooter, earthquakes, and so on. 
       FIG. 1  illustrates a district wide interconnected and centrally administered school district communication system  100 . As illustrated in  FIG. 1 , a plurality of school campuses  104 , each with an individual school communication system, are organized into the school district communication system  100 . As illustrated, the plurality of school campuses  104  are interconnected through a district network  106 , which in turn interfaces the plurality of school campuses  104  with a district datacenter  102 . The district datacenter  102  includes a server or servers each with an associated processor or processors running a networked application controlling a communication system within each of the plurality of school campuses  104 . The networked application provides school district administrators with the ability to control all communication among the plurality of school campuses  104 . This control is provided through a user interface, which allows control over bell schedules, announcements and other calendar management tools along with enabling drills and emergency notifications for lockdown, lock out and evacuation events. The district datacenter  102  configures and stores emergency drills for each school campus  104  and also stores reports generated from the emergency drills at each school campus  104 . School administrators access this user interface via a user computer system  110 , which is communicatively coupled to the district network  106 . 
     In a particular embodiment, the user interface may be a web-based user interface, and the user computer system  110  can be any computer system that is capable of communicating with the district network  106  over the web-based user interface. For instance, the computer system  110  may take a variety of forms such as a mobile device, tablet device, laptop computer or any device capable of communicating with the web-based user interface. 
     Further, access to the web-based user interface from the user computer system  110  is granted based on an administrator&#39;s or user&#39;s login credentials. Any time a user accesses the web-based user interface, login credentials will be required before any functionality is provided. The login credentials not only provide access to the web-based user interface, but they also provide a level of access to the communication systems at the plurality of school campuses  104 . For instance, in certain embodiments, the plurality of school campuses  104  may include individual school campuses  1 -N,  108   a ,  108   b  and  108   c , and the individual user may only be authorized to control the communication system at a single campus such as school campus  1   108   a . Therefore, upon entering the user login credentials, the district datacenter  102  administrating the web-based user interface will look up the user&#39;s level of access and provide control only according to that access via the web-based user interface. 
     In certain embodiments, the district datacenter  102  further includes an integrated computer terminal that hosts a microphone  112 . The microphone  112  is configured to allow a user to provide audio to the microphone  112 , which can be streamed to any communication system at any campus  108   a ,  108   b  or  108   c  within the district. As an aside, each individual school communication system (see  FIG. 2 ) can also include an integrated computer terminal that hosts a microphone client into which a microphone can be integrated such that an audio signal from the microphone can be broadcast over the individual school communication system. Emergency drills can be initiated at either the district level (e.g., via the district datacenter  102 ) or at the school level (e.g., via any of the plurality of school campuses  104 ). 
       FIG. 2  illustrates the components of the school communication system  200  for individual school campus  108   a  (individual school campuses  108   b  and  108   c  may include school communication systems similar to school communication system  200 ). The school communication system  200  includes a switch/router  202 , which provides a shared network connection for the various components of the school communication system  200  to the district network  106  (see  FIG. 1 ). The various components of the school communication system  200  are distributed throughout a plurality of zones, which define physical spaces within the school campus  108   a . In this regard, each zone has zone specific communication equipment associated with the district location/school campus  108   a.    
     Components of the school communication system  200  may include a campus controller  204 , a room or classroom controller  206 , a zone controller  212 , an administrative console  214 , status indicator lights  216   a  and  216   b , a message board  218 , and an Auxiliary Input/Output (Aux IO) module  220 . The campus controller  204  is an embedded interface for all of the campus devices located at the campus  108   a  to the district datacenter  102  (see  FIG. 1 ). In this regard, the campus controller  204  functions to provide the interface for the classroom controller  206 , the zone controller  212  and the administrative console  214  to the district datacenter  102 . The campus controller  204  functions as a Session Initiation Protocol (SIP) Gateway, including processors and memory devices that enable the campus controller  204  to provide communication to/with various communication equipment, or, in other words, the campus communication equipment, including the classroom controller  206 , the zone controller  212  and the administrative console  214 . Communication equipment in general includes the call switch  210 , the speaker  208 , lights  216   a  and  216   b , microphones (not shown), the administrative console  214 , and controllers associated with each of these devices. The campus controller  204 , in some embodiments, can also control relays on the Aux IO module  220  within the campus  108   a . Relays on the Aux IO module  220  can be used, e.g., to disable doors and elevators. In this regard, the campus controller  204  functions to provide full paging, pre-recorded audio, live audio, intercom audio, and other control signals to any single campus device or combination of campus devices located within any number of zones throughout the campus  108   a . Typically, the campus controller  204  interprets instructions received from the district datacenter  102  (see  FIG. 1 ) by parsing those instructions to determine embedded communication events. The campus controller  204  then optionally stores/archives those instructions with an associated memory (not illustrated) and transmits the instructions in the form of a control signal to various campus devices such as those shown in communication system  200  and discussed above. 
     The school communication system  200  further includes the classroom controller  206  associated with each classroom of the school at campus  108   a . In certain embodiments, each classroom can be considered a separate zone within the campus  108   a . The classroom controller  206  communicates via IP-based signals and interfaces with the campus controller  204  through the switch/router  202  such that it sends/receives data to/from the campus controller  204 . In this manner, the classroom controller  206  functions as an IP room module. The classroom controller  206  interfaces with a speaker  208 , an in-room strobe or alert light (not illustrated), one or more switches or buttons such as a check-in or call switch  210 , and a status indicator light  216   a  over a digital interface. 
     In certain embodiments, the speaker  208  interfaces with the classroom controller  206  through a bi-directional amplifier (not illustrated) which allows for the speaker module  208  to function as both a speaker and a microphone for the classroom controller  206 . Typically, communication will be between the classroom controller  206  and the administrative console  214  or an external phone system and is controlled by the campus controller  204 . The call switch  210  allows for personnel within the classroom containing the classroom controller  206  to call into the administrative console  214  or perform a check-in during an emergency situation. The classroom controller  206  can also trigger a visual indicator such as an in room strobe light or alert light upon receiving a command to do so from the campus controller  204 . The classroom controller  206  can further trigger a visual indicator external to the classroom from the status indicator light  216   a  upon receiving a command to do so from the campus controller  204 . 
     School communication system  200  further includes the zone controller  212 , which functions in a similar manner to the classroom controller  206 . Typically, a school will include a plurality of zones, other than classrooms, which comprise various locations throughout the school and campus in general. Typically, each non-classroom zone within the school will include at least one zone controller  212 . The zone controller  212  decodes IP-based signals from the campus controller  204  into signals for controlling a status light indicator  216   b . The zone controller  212  communicates these control signals to the status indicator light  216   b  over a digital interface. The school communication system  200  further includes the administrative console  214 , which, in certain embodiments, provides a single point of access to the school communication system  200 . In this regard, the administrative console  214  is equipped with various interfaces, speakers and microphones for communication within the school communication system  200 . The administrative console  214  can initiate classroom intercom discussion over the classroom controller  206 , perform zone or system-wide pages and receive visual alerts from classroom communications over a display associated with the administrative console  214 . In certain embodiments, the administrative console  214  can also perform pre-programmed sequences for the school communication system  200 , such as initiating an emergency sequence. 
     As mentioned above, the administrative console  214  includes an associated display. In certain embodiments, during an emergency event, the display can be configured to function as a centralized emergency console or in other words an emergency display console that can display check-in information for each zone or classroom within the school campus  108   a  (see  FIG. 1 ). Check-in information indicates that a classroom has checked in by pressing the call switch  210  during the emergency event and thereby indicates that the particular classroom associated with that call switch  210  is not in an immediate emergency. In this regard, first responders to an emergency situation will have a single point where immediate status of the various classrooms and zones within the school campus  108   a.    
     In an embodiment, the administrative console  214  can also aggregate call switch  210  signals, received via the campus controller  204 , during an emergency drill which can be interpreted as students complying with instructions provided during the drill. The call switch  210  signal interpretation is dependent on the type of drill. For example, in an active shooter drill, the call switch  210  can be used to alert a location of a potential active shooter. In an emergency drill that requires moving students to designated locations, e.g., tornado safe locations, call switch  210  signals can be used to confirm classrooms that are evacuated. That way, the campus controller  204  can keep track of time elapsed between alerting students of the emergency drill and when a classroom is evacuated. The administrative console  214  can display information about the time elapsed determined by the campus controller  204 . As an aside, an administrative console  214  is not required to be the centralized emergency drills console. 
     The campus controller  204  can receive emergency drill configurations from the district level via the district network  106 . This setup allows a uniform standard for emergency drills across each campus in the plurality of campuses  104 . This setup also allows for uniformity in messaging so that audio messages used during emergency drills can be updated at the district level and propagated to each campus in the plurality of campuses  104 . After each emergency drill, the campus controller  204  can generate a report to be stored at the district level via the district network  106 . 
     In an embodiment, an emergency drill configuration is different from an emergency based on steps being omitted. For example, Table 1 provides steps performed during an emergency. The steps performed during an emergency are performed according to the Order number. Steps identified with an “X” under Drill are performed in both emergencies and emergency drills while the other steps are performed only during an emergency.

     From Table 1, the district level can modify configurations of emergency drills by adding one or more steps, removing one or more steps, marking a step as being a step performed under Drill, or unmarking a step as being performed under Drill. For each emergency drill, the district datacenter  102  can generate a report whether the drill was successfully performed. 
     With respect to the emergency situation discussed above, Table 1 below illustrates a particular embodiment showing a relation between events that may take place during a lockdown sequence and their associated lighting and audio actions. In certain embodiments, the following lockdown sequence may be initiated or terminated from a designated pushbutton, computer, administrative console or SIP telephone. A user computer system  110  (see  FIG. 1 ) can be used to modify and tailor emergency drill configurations received from the district level. 
     Table 2 provides examples of actions and parameters for each action that can be set according to some embodiments of the disclosure. Example actions include playing a preconfigured audio message, sending preconfigured email messages, turning relays ON and OFF, toggling swings, including time delays, controlling status lights, displaying messages on message boards, and making prerecorded telephone calls.

     In Table 2, drill action configuration can be read from a user computer system  110  (see  FIG. 1 ). In an embodiment, the user computer system  110  provides individual campuses ability to add actions specific to their campus. That way, campuses can tailor the district&#39;s mandated emergency drills to their specific needs. For example, a campus can broadcast an evacuation message to direct students to specific safe areas of the campus, such as a library, a basketball gym or other such spaces. 
     In Table 2, for example, the campus controller  204  can direct the speaker  208  to play a preconfigured audio message. In an embodiment, the audio message can be received from the district level via the district network  106 . In some embodiments, the audio message is retrieved from storage accessible to the campus controller  204 . The campus controller  204  determines where to play the audio based on location parameters within the emergency drill configuration. For each action, since parameters can be set to custom values, a name parameter can be used to identify different actions. 
     In an embodiment, the campus controller  204  can send preconfigured email messages to certain email addresses. In an emergency, emails may be sent to parents informing them of the emergency; however, during a drill, a school campus may likely not send email to parents just like they would not alert emergency services. In the practice emergency drill scenario, the campus controller  204  can remove parents from the list and alert administrators, staff members, or district level administrators that a certain drill was performed or is underway. 
     In an embodiment, the campus controller  204  can turn relays ON or OFF on aux IO modules, such as aux IO module  220 . These relays can be used to control various mechanical switches such as door locks and other such devices. For instance, during a campus lock down, the aux IO  220  may be utilized to actuate a door lock to lock down a portion of the campus  108   a  (see  FIG. 1 ). 
     In an embodiment, the campus controller  204  can include delays just like “Delay” shown in Table 1. This allows a smooth transition from one action to another and gives the emergency drill system a way to control when one action follows another. When building a drill event, a user can add a delay to make sure one event occurs before another. 
     In an embodiment, the campus controller  204  can control status lights during emergency drills at different locations within the campus. The status light can be set to indicate what type of emergency drill is currently executing. 
     In an embodiment, the campus controller  204  can send a preconfigured voice message to private branch exchange (PXB) extensions so that it can reach telephone lines. In this manner, a voice message can be communicated to an outside telephone device. For instance, during an emergency, the drill could function to send a voice message to one or more telephones updating the recipient of the voice message about the emergency. 
     In an embodiment, the campus controller  204  can control message boards during emergency drills at different locations within the campus. The message boards can be set to indicate a type of emergency drill currently executing. Alternatively, the message board can indicate a status of the emergency or any other relevant type of message useful during execution of the emergency drill. 
     In general, functionality described can be set up via the web based user interface from the user computer system  110  (see  FIG. 1 ).  FIG. 3  illustrates an emergency drill performance process  300 . The process  300  provides exemplary steps performed by the campus controller  204  with the aid of the school communication system  200  (see  FIG. 2 ). At step  302 , the campus controller  204  receives an emergency drill configuration. The emergency drill configuration can include one or more actions to be performed during an emergency drill. The emergency drill configuration can include specific actions in an emergency action file that should be designated as drill steps. An action can be configured according to Table 2 with parameters as described in Table 2. In an embodiment, an emergency action file, e.g., one indicating actions in Table 1, is loaded by the campus controller  204 , and the emergency drill configuration indicates which actions within the emergency action file are actions to be performed during a drill. The emergency action file and the emergency drill configuration can be received from the district level via the district network  106 . 
     At step  304 , the campus controller  204  receives a signal to begin an emergency drill. In an embodiment, the emergency drill is based on the emergency drill configuration received at step  302 . The signal can be received from the district level via the district network  106 . For example, the user computer system  110  can send the signal to the campus controller  204  to begin the emergency drill. In another embodiment, the administrative console  214  can send the signal to the campus controller  204  to initiate the emergency drill. In another embodiment, the campus controller  204  receives a signal from an aux IO module  220  to initiated the drill. 
     At  306 , the campus controller  204  performs one or more actions in the emergency drill. In an example, if the action to be performed includes playing an audio file, the administrative console  214  instructs the campus controller  204 , room controller  206 , and/or the zone controller  212  to play the specific audio file via speakers. The action will include which locations the audio should be played. In an example, the campus controller  204  determines whether an action is included in the emergency drill by checking a drill flag of the action. The campus controller  204  can select which actions to perform based on the drill flag. The campus controller  204  can perform actions based on the order of each action, where actions with lower orders are completed before moving on to an action with a higher order. 
     At  308 , the campus controller  204  confirms and records that the drill was initiated. Once the drill is initiated, the drill will run loop back to step  306  to perform additional steps of the drill until each of the steps is completed or terminated. 
     For example, during an evacuation drill, such as a fire drill, students at the campus performing the drill must evacuate the various classrooms. During the drill, a teacher or other room supervisor may actuate a call switch  210  once a room is completely evacuated. The campus controller  204  waits for the call switch  210  signals from one or more rooms that indicate that students have evacuated to designated areas based on the action to be performed. As the call switches  210  from the one or more rooms are pushed, the campus controller  204  can use a timeout signal to rank certain rooms within the campus that fail to meet a certain evacuation time limit. As this is happening, the process  300  loops from step  308  back to step  306  to perform each additional step in the drill. 
     Once each step of the drill is executed, or the drill is terminated, the process  300  proceeds to step  310 . At step  310  the drill stops and a report is generated. In an embodiment, the report is generated only when specifically requested by a user using the user computer system  110  (see  FIG. 1 ), and the report indicates whether the drill was successfully initiated. In other embodiments, the reports may provide a variety of relevant details about the drill execution that may be used subsequently to analyze the response to the drill and show compliance with various standards associated with emergency response drills. 
     Embodiments of the disclosure provide a system for initiating and guiding emergency drills such that organizations and facilities no longer need to manually initiate and guide the emergency drill. Potential avenues for human error are drastically reduced because the amount of human interaction time to coordinate emergency drills in a school is reduced. Furthermore, state regulatory agencies or other oversight agencies can readily access reports or documents for emergency drills. This provides an efficient way to audit emergency drill execution for purposes of compliance.
