## Title
Connection system of building facility device managing system, connection method of building facility device managing system, and connection program of building facility device managing system

## Abstract

Operations of a building facility monitoring device and an IP network monitoring device are coordinated with each other. In a connection system of a building facility device managing system, when a status of the IP network monitoring device is changed, a monitoring-device-status managing unit 301 provides parameter information unique for a BACnet protocol to the changed status and stores it. If the status is not an operation command, a coordinated-packet-generation transmitting/receiving unit 302 generates a packet of the BACnet protocol based on a status and parameter information of a specific IP network monitoring device to transmit it to a building facility device managing system 103. If the status is the operation command, it acquires a status and parameter information of the specific IP network monitoring device from a management database 401, and generates a packet of the BACnet protocol based on the status and the parameter information to transmit it to the building facility device managing system 103.

## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is entitled to the benefit of and incorporates by reference essential subject matter disclosed in International Patent Application No. PCT/JP2012/55958 filed on Mar. 8, 2012 and Japanese Patent Application No. 2011-229348 filed Oct. 19, 2011.
TECHNICAL FIELD
The present invention relates to a connection system of a building facility device managing system, a connection method of a building facility device managing system, and a connection program of a building facility device managing system, which connect the building facility device managing system for managing a plurality of building facility monitoring devices with an IP network device managing system for managing an IP network monitoring device such as a router and a personal computer. More particularly, the present invention relates to a connection system of a building facility device managing system, a connection method of a building facility device managing system, and a connection program of a building facility device managing system, which can coordinate operation of the building facility monitoring device connected to the building facility device managing system with operation of the IP network monitoring device connected to the IP network device managing system.
BACKGROUND ART
Generally, in building facility of a company or others, a building facility device managing system for integrally controlling a plurality of building facility monitoring devices for a plurality of air conditioners, lighting devices, door opening/closing devices, and others is installed via a network. Each building facility monitoring device and the building facility device managing system are connected to each other via the Ethernet (Registered trademark) whose communication is generalized with using a communication protocol such as “BACnet” (Building Automation and Control Networking protocol: communication protocol standard for intelligent building network) and “Lontalk” (Local Operation Network: communication protocol standard for connecting a device such as a lighting device, a switch, and a temperature sensor mounted with a neuron chip for operation). On the other hand, in building facility of a company or others, a computer network has been structured along with development of a computer technology so that a lot of personal computers and IP monitoring cameras are connected to a server via an IP network such as LAN based on TCP/IP protocols. However, specifications of the BACnet and the Lontalk which are communication standards on the above-described building facility device managing system side are different from those of the TCP/IP protocols which are communication standard on the IP network device managing system side.
Note that Japanese Patent Application Laid-Open Publication No. 3366228 is cited as a document describing a technique of performing network connection based on a different protocol. This document describes a technique by which the SNMP protocol and the non-SNMP protocol are accessible from each other so that all devices in the network can be monitored and controlled by one monitoring control device, by providing: means for identifying that a signal of a SNMP protocol received from a transmission-source device connected to a network is to be converted into which non-SNMP protocol; means for converting the signal into the non-SNMP protocol used by a transmission-destination device connected to another network with reference to a conversion table prepared by the identifying means, and then, transmitting it to the transmission-destination device; means for identifying that a signal of the non-SNMP protocol received from the transmission-source device connected to the network is to be converted into what type of the non-SNMP protocol; and means for converting the signal into the SNMP protocol used by the transmission-destination device connected to the network with reference to the conversion table provided by the identifying means, and then, transmitting it to the transmission-destination device.
DISCLOSURE OF THE INVENTION
As the technique described in the above-described Japanese Patent Application Laid-Open Publication No. 3366228, it is described that a SNMP protocol and a non-SNMP protocol are converted into a non-SNMP protocol used by a transmission-destination device connected to another network with reference to the conversion table between the SNMP protocol and the non-SNMP protocol in order to connect between the networks based on different protocols. However, the building facility device managing system and the IP network device managing system are not coordinated with each other while they control a plurality of individual devices, and therefore, there is a problem that it is difficult to provide building-facility users with advanced building environment.
This problem will be specifically explained as follows. In an IP monitoring camera used as a device for security, image monitoring and operation can be performed from only a terminal device of the building facility device managing system installed in a security guards room or others, and therefore, control such as zoom control and pan control of the IP monitoring camera with using a computer screen installed in other division such as a general affairs department of a company cannot be performed. For example, there is a failure that, even if smoke is detected by a smoke detector which is a disaster-prevention device, fire or others cannot be checked from the building facility device managing system with operating the IP monitoring camera, and there is a problem that it is difficult to provide building-facility users with the advanced building environment under which variously-installed building facility monitoring devices are utilized.
A preferred aim of the present invention is to solve problems caused by the above-described conventional techniques, which is to provide a connection system of a building facility device managing system, a connection method of a building facility device managing system, and a connection program of a building facility device managing system, which can coordinate operation of a building facility monitoring device managed by a building facility device managing system with operation of an IP network device managed by an IP network managing system.

In the connection system, the IP network device managing system includes: a management database in which statuses of the building facility monitoring device and of the IP network monitoring device and parameter information of the IP protocol and the BACnet or Lontalk protocol are stored; a monitoring-device-status managing unit which stores the parameter information for filling a difference in a specification between the IP protocol and the BACnet or Lontalk protocol into the management database with being numbered when the status which is a state of the IP network monitoring device has been changed; and a coordinated-packet-generation transmitting/receiving unit which receives a command from the building facility device managing system and which generates a packet of the BACnet protocol based on the status and the parameter information acquired from the management database to transmit it to the building facility device managing system. The monitoring-device-status managing unit executes a first step when the status received with using the IP protocol from the IP network monitoring device has been changed from the status stored in the management database, the first step of providing the parameter information unique for the BACnet or Lontalk protocol to the changed status and storing it.

More specifically, as illustrated in FIG. 7B, on the building facility monitoring device side, for a lighting having the “Host Name” of “blank” because it is not the building facility monitoring device, the “Status” is stored as “1” (activation), the “Parameter” is stored as “power”, the “Object Type” is stored as “1”, the “Instance No.” is stored as “11”, the “Camera Zoom” and the “Preset Temperature” are stored as “blank” because it is the IP network monitoring device. For a disaster-prevention device having the “Host Name” of “blank” because it is not the building facility monitoring device, the “Status” is stored as “0” (stop), the “Parameter” is stored as “power”, the “Object Type” is stored as “1”, the “Instance No.” is stored as “12”, the “Camera Zoom” and the “Preset Temperature” are stored as “blank” because it is the IP network monitoring device.

That is, the management database 401 according to the present embodiment stores data whose one record is formed of the respective items (parameter information) which are: the “Host Name” contained in the IP network protocol; the “Status” indicating the state of the monitoring device contained in the protocol of the building facility monitoring device; the “Parameter” indicating the type of the parameter of the monitoring device contained in the protocol of the building facility monitoring device; the “Object Type” of the monitoring device contained in the protocol of the building facility monitoring device in order to identify either the building facility monitoring device or the IP network monitoring device; the “Instance No.” provided individually as the identifier in order to identify each of individual building facility monitoring devices and IP network monitoring devices; and the “Camera Zoom” and the “Preset Temperature” for controlling individually the IP network monitoring devices, and is configured to register each packet item used for a packet signal of the building facility device managing system and the IP network device managing system.
In the embodiment, note that the lighting, the air conditioner, and the disaster-prevention device (fire detector, smoke detector) are cited as the object devices monitored by the building facility device managing system, and the personal computer, the router, and others are cited as the object devices managed by the IP network device managing system. However, the devices to be objected in the present invention are not limited to these devices, and, for example, a lock device of the building, and an opening/closing (monitoring) device of a window or a door thereof, and other devices may be the objects, and therefore, in accordance with the object devices, a logical name to be stored in the management database 401 can be also added, or panning can be also added as another operation of the IP monitoring camera.
Incidentally, in the computer system which achieves the connection system of the building facility device managing system, the connection method of the building facility device managing system, and the connection program of the building facility device managing system according to the present embodiment configured as described above, when the status of the IP network monitoring device is changed, the operation is performed so as to store this status change together with the newly-provided “Parameter” and “Instance No.” by making the monitoring-device-status managing unit 301 execute steps as illustrated in FIG. 5, the steps including: a step “A01” of activating a resident service for receiving a packet containing a status change signal from the IP network monitoring device 106; when a packet containing the status change signal is transmitted from the IP network monitoring device 106 or when the packet containing the status change signal is received by the resident service of the step A01, a step “A02” of receiving the status change signal received from the IP network monitoring device 106 by the connection program 201 of the building facility device managing system of the IP network device managing system 108; a step “A03” of extracting the information of the object IP network monitoring device received by the step A02 based on the Host name and of reading the information from the management database 401; a step “A04” of comparing the received status indicating whether the device status is changed or not which is read by the step A03 with the read status, of determining whether or not, and of returning to the step A02 if no change is determined; if the change is determined in the step A04, a step “A05” of overwriting (updating) the status of the IP network monitoring device whose status has been changed into the newest status over the management database 401; and a step “A06” of newly numbering the “Parameter” and the “Instance No.” for the building facility device managing system which are not contained in the packet of the IP network monitoring device whose status has been changed for the record of the IP network monitoring device whose status has been changed, the record stored in the management database 401, of storing them in the management database 401, and of terminating the process.
Therefore, for example, when power supply of a specific personal computer is turned off so that it is turned into a stop state, the monitoring-device-status managing unit 301 according to the present embodiment can store the stop state (“Status”) indicating the power-supply OFF of this specific personal computer and the numbered “Parameter” and “Instance No.” in the management database 401, and can also perform similarly to other IP network monitoring devices.
Next, the computer system including the connection system of the building facility device managing system according to the present embodiment is operated, when inquiry for the IP network monitoring device is issued from the building facility device managing system, so as to read the “Status” of the corresponding device from the management database 401, and besides, so as to generate an inquiry packet for the building facility device managing system 103 with the read “Status” together with the “Parameter” and the “Object Type” (also including the items of the “Camera Zoom” and the “Preset Temperature” depending on the device) to transmit it by making the coordinated-packet-generation transmitting/receiving unit 302 execute steps as illustrated in FIG. 6, the steps including: a step “B01” of activating a resident service for receiving a packet containing an inquiry command signal or an operation command signal for the device operation from the building facility device managing system 103; when the packet containing the inquiry command signal is transmitted from the building facility monitoring device 101, a step “B02” of receiving the packet containing the inquiry command signal by the IP network monitoring device managing system 108 with using the resident service of the step B01; a step “B03” of determining whether the received packet contains the inquiry command signal or not; if it is determined in the step B03 that the status inquiry command signal to the IP network monitoring device 106 is contained, a step “B04” of reading the “Status” of the objective IP network monitoring device 106 from the management database 401; a step “B05” of generating a packet for the building facility device managing system 103 based on the “Status” read by the step B04; and a step “B06” of transmitting the packet for the building facility device managing system 103 which has been generated by the step B05 to the building facility device managing system.
Subsequently, the operation of the IP network monitoring device is instructed by making the coordinated-packet-generation transmitting/receiving unit 302 according to the present embodiment execute steps when it is determined in the step B03 that the status inquiry signal to the IP network monitoring device 106 is not contained, the steps including: a step “B07” of determining whether the operation command signal to the IP network monitoring device 106 is contained in the received packet or not and of terminating the process if it is determined that the operation command signal is not contained; if it is determined in the step B07 that the operation command signal is contained, a step “B08” of reading the “Status” of the corresponding device from the management database 401; a step “B09” of generating a command packet for the building facility device managing system 103 with the “Status” of the objective IP network monitoring device read by the step B08 together with the “Parameter” and the “Object Type” (also including the items of the “Camera Zoom” and the “Preset Temperature” depending on the device); and Step B10 which transmits the instruction packet generated by the Step B09 to the IP network device managing system 108.
The computer system including the connection system of the building facility device managing system according to the present embodiment can coordinate the building facility device managing system with the IP network device managing system by, when the “Status” indicating the state of the IP network monitoring device 106 is changed as illustrated in FIG. 5, storing the Status change based on the IP network monitoring device 106 into the management database 401 with adding the “Parameter” and the “Instance No.” for the building facility device managing system 103 executed by the monitoring-device-status managing unit 301, and besides, when the IP network monitoring device inquiry command or the IP network monitoring device operation command is received from the building facility device managing system 103 as illustrated in FIG. 6, by generating a packet with adding the inquiry command or the operation command to the “Parameter” and the “Instance No.” for the building facility device managing system 103 to be stored in the management database 401 executed by the coordinated-packet-generation transmitting/receiving unit 302.
This coordination will be specifically described as follows. For example, in a case that the power supply to the personal computer which is the IP network monitoring device is turned off, the monitoring-device-status managing unit 301 registers the power-supply OFF (state: “Status”) of this specific personal computer into the management database 401 by executing the process illustrated in FIG. 5, and, when the building facility device managing system 103 transmits the signal based on the instruction from the managing computer 104 of the system administrator, the coordinated-packet-generation transmitting/receiving unit 302 transmits the power-supply OFF (state: “Status”) of the personal computer to the building facility device managing system 103 by executing the process at the upper stage of FIG. 6, so that the administrator of the managing computer 104 connected to the building facility device managing system 103 which has received this state can turn off the power supply to the air conditioner and the lighting which are the building facility monitoring devices in a room where the corresponding personal computer is located with using the building facility device managing system 103, or can make the building facility device managing system 103 instruct the coordinated-packet-generation transmitting/receiving unit 302 to perform the operation of the zoom-in, the panning, or others of the IP monitoring camera which is the IP network monitoring device by executing the process illustrated in FIG. 6 when the smoke detector for disaster prevention which is the building facility monitoring device detects smoke.
As another example, in the computer system including the connection system of the building facility device managing system according to the present embodiment, in a case that restart of the router which is the IP network monitoring device is required because failure occurs in the router, the building facility device managing system 103 can instruct the coordinated-packet-generation transmitting/receiving unit 302 to perform the stop and restart operations for the router by executing the process illustrated in FIG. 6. In a case that the IP network device managing system 108 detects increase of a temperature of the same router up to a predetermined temperature or higher, the monitoring-device-status managing unit 301 registers the fact of the predetermined temperature or higher into the management database 401 by executing the process described in FIG. 5, and the coordinated-packet-generation transmitting/receiving unit 302 transmits the temperature anomaly of the router to the building facility device managing system 103 by executing the process at the upper stage in FIG. 6, so that the administrator 104 of the managing computer connected to the building facility device managing system 103 which has received this temperature anomaly can control a temperature of an air conditioner which is the building facility device in a room where the corresponding router is located with using the building facility device managing system 103.
While the present invention has been illustrated and described with respect to a particular embodiment thereof, it should be appreciated by those of ordinary skill in the art that various modifications to this invention may be made without departing from the spirit and scope of the present.
