## Title
Method of retrieving and uniformalizing elevator maintenance and callback data and code events

## Abstract

Elevators and escalators produce code event data, and also have associated maintenance data and callback data. This data is collected and stored in different formats for different types of elevators and escalators, as well as their respective controller devices. Systems and methods are provided that include elevator controllers that transmit code events to a business partner by means of a web services application. The code events data comprising elevator performance data that is collected and stored by the elevator controllers in different formats, and the different formats correspond to different types of the elevator controllers. The business partner obtains the code events data, uniformalizes the code events data, and presents the code events data by means of a web application. Other user devices, via a mobile web application, can access the uniformalized data and, initiate and control callbacks for a given elevator.

## Background
FIELD
The invention relates to the field of elevator/escalator maintenance data, and in particular, retrieving, uniformalizing and storing maintenance and callback data from service providers and elevating device controllers.
BACKGROUND
Often, facility owners have multiple elevator/escalator service providers that maintain and repair their equipment, which is generally manufactured by various manufacturers. The service provider provides regular maintenance visits on a monthly, quarterly, or annual basis, as well as support in case of emergency (“callback”).
Callback is generally initiated by facility owners via calling the service provider. Once initiated, the service provider enters the information into its internal system and dispatches a technician. The information generated from the call and the dispatch becomes a part of the callback history. Facility owners are able to monitor and access the callback history from the service providers website. This is shown in FIG. 1.
Whether facility owners have a single building or multiple buildings, they generally have multiple service providers. With the use of multiple service providers, facility owners are forced to manage multiple accounts in order to access the different web applications from each service provider. Additionally, the various service providers utilize different codes, formats and presentations with respect to their data files. This is shown in FIG. 2. As such, it is a mammoth task to collect and interpret the information from the various service providers, as there is no uniformalization of information storage among the various service providers. To further complicate this situation, service providers' files are not always available, and are typically accessible only on an on-demand basis.
At the conclusion of a contract for services, facility owners may decide not to extend the contract with the service providers depending on multiple factors (e.g., quality of service, new service provider offers, etc.). When the contract between the facility owner and the service provider is terminated, the facility owner no longer has access to data that was stored by the service provider during the contract tenure. As a result, the callback and maintenance history is no longer available to the facility owner.
Since elevators and escalators have become computer controlled, they store elevator codes or events (e.g., information on the heat detectors or landing sensors) in the controller. Unfortunately, elevator/escalator code/event information is stored in a form that is proprietary to each manufacturer, and usage and maintenance data from different manufacturers cannot be compared.
Technicians who service elevators and escalators access the data from the controller and are able to access various statistical data, events of use and the last service intervals from each elevator. From this data, technicians are able to facilitate servicing of the equipment and anticipate problems before they arise.
Currently, the facility owner is able to access the controller's event and code remotely. Generally, the facility owner would install an application to gain remote access to the controller via a remote computer. Due to the direct connection between the controller and the facility owner's computer, the facility owner must be at the computer in order to open and view the event and code from the controller. This is shown in FIG. 3. As a result of the direct connection between the controller and the computer, the facility owner has to manage multiple accounts and computers. Additionally, the facility owner has no backup in case of data failure/disaster recovery. Further, the facility owner has to rely on a technician to analyze the event and code to identify or anticipate problems.
Comparison of maintenance and usage data from various manufacturers is beneficial as it enables streamlining of maintenance procedures and comparison of elevators under different usage circumstances. However, a method of uniformalizing has not been heretofore disclosed in the prior art. Therefore, there is a need to retrieve and uniformalize elevator usage and maintenance data.
SUMMARY
The invention relates to a method for data retrieval and uniformalization of code events data for an elevator, where any number of various service providers transmit code events from an elevator controller to a business partner through a web services application. The business partner retrieves and uniformalizes the data, and then presents the data through a web application. The data is uniformalized by mapping it into the database of the web server with data restrictions, and then converting the data to match those data restrictions. In one embodiment, the business partner can back up the data on a web server. In another embodiment, the data can be XML webservices data and can be retrieved, uniformalized and stored on a datastore.
The invention also discloses another method for data retrieval and uniformalization. In such an embodiment, a service provider stores elevator data and transmits that data to a web services application. A business partner then retrieves that data through the web services application, uniformalizes the data, and then stores the data in a business partner web server. In another embodiment, the data can be data concerning elevator maintenance and service calls. The data is uniformalized by determining a mapping for the data into the database of the web server with data restrictions, and then converting that data to match its restrictions. In a separate embodiment, the data can be XML webservices data and the data can be retrieved, uniformalized and stored on a datastore. In another embodiment, a manufacturer application and API can be installed, where the manufacturer application and API transmit data to the web services application, allowing remote access by the end user. In yet another embodiment, the business partner can back up the stored data on a web server. In another embodiment of the present invention, the business partner may present the uniformalized data through an intuitive web application. The data from more than one elevator can be shown simultaneously in the web application. In yet another embodiment, the user can initiate and control callback by using a web services application, as well as communicate with the service provider through web services to make a call for service. In another embodiment, the business partner can set up web services for mobile applications, which allows mobile communication for the service provider with the business partner's datastore. The end user can then initiate a call using the business partner mobile application, communicating with the service provider through web services that makes a call for service of an elevator. In another embodiment, the end user can control callback by accessing the business partner's web server and initiating a call using a web services application. The web server can have a single sign on. In another embodiment, a standard presentation may display information from one or more service providers. In another embodiment, the web application can analyze datasets, display performance and deficiency information, and send out notifications to a single individual or multiple concerned parties.

DETAILED DESCRIPTION
With reference to FIG. 4, an embodiment of the data retrieval and uniformalization process for elevator/escalator (referred to generally as “elevator”) maintenance and callback data is described. FIG. 4 relates to service providers that provide maintenance and standby on call service. The service providers perform standard maintenance, and store the maintenance information on the service provider's data storage. Furthermore, the service provider may be called (“service call”) by the user to rectify an issue with an elevating device, in which case the service provider will repair the elevator, and again store the service call information on the service provider's data storage. There is therefore information on both i) maintenance and ii) service calls on the service provider's data storage. The service provider has a web application that allows a user to log in and track the information and status of the maintenance and service call completed by the service provider. In step 5 any number of various service providers provide access to the respective service provider's data storage, and transmit that data to the business partner via a web services application, through a network such as the Internet. In step 10 the business partner retrieves the data from the network via a web services application. In step 15 the data is uniformalized and stored in the business partner facility. In the data retrieval and uniformalization process, the information using XML webservices is retrieved, uniformalized and stored on the Datastore. In step 20 the stored data is backed up by the business partner on a web server, and made available to the end user through a web application usable on fixed devices such as computers or mobile devices (e.g., smartphones, tablets and laptop computers). In step 25 the end user gains access to the business partner's web server via the Internet, allowing the end user to initiate and control callback by initiating a call or contact such as email or SMS using a web services application, which then communicates with the service provider system through web services to make a call for service of the elevator. In step 25 the end user may initiate and control callback by initiating a call using a web services application, which then communicates with the correct service provider system through web services to make a call for service of the elevator. The information from all service providers is uniformalized into the Datastore and may be presented intuitively on a web application at step 20. In step 30 a web services for mobile application is set up by the business partner to allow mobile communication for the mobile application with the business partner's Datastore, so that the user may receive operating data at the elevator site or on the road. In step 35 the end user can control callback by initiating a call using business partner mobile application, which then communicates with the service provider system through web services for mobile application.
With reference to FIG. 5, another embodiment of the data retrieval and uniformalization process is described. FIG. 5 references controllers 37, which are devices built by disparate manufacturers, are installed on the machine room and control the operation of the elevator 38. The controllers 37 collect and store data regarding the performance and service of each of the elevating devices, such as storing code events. Examples of code events are Heat Detectors, Recall Activated, Landing System Sensor Fault and Emergency Power Activated. A user can see events or codes for an elevator 38 from a computer which has a direct connection to the controller 37. The present embodiment receives code events using XML webservices and stores them in the Datastore and uniformalizes them. In step 40 any number of various elevator controllers 37 store code events through its connection with the elevator sensors 39. In step 45 the code events stored in the manufacturer controller is transmitted to a remote computer via a manufacturer network card. In step 55, a manufacturer application and API would generally be installed to allow remote access by the user. In step 60 the manufacturer application and API transmit data to web services application. In step 65 the business partner retrieves the data from the network via the web services application. In step 70 the data is uniformalized and stored in the business partner facility. In step 75, optionally, the stored data is backed up by the business partner on a web server. The uniformalized data may be presented through an intuitive web application. In step 80 the end user gains access to the business partners web server via the Internet, allowing the end user to see data regarding the code events that have been created by an elevator 38. In step 85 a web services for mobile application is set up by the business partner to allow mobile communication with the business partners datastore. In step 90 the business partner mobile application can access the controller code events data through web services.
With reference to FIGS. 6a-c and 7a-c, sample datasets are shown. In FIG. 6a, table Activities contains activities having a unique activity id 102, a company id 104, a location id 106 which is tagged to the location of the elevating device, and a device id 108, to identify a unique elevating device. The maintenance information is stored in the form of work description 110, repair description 112, the entered and completion dates 114, 116 and the work order number 118. The invoicing information may be contained as invoice number 120, estimated cost 122 and actual cost 124. The callback information includes a callback id 123, directive code 125, deficiency number 126, government-mandated code 127, counter 128 for the number of occurrences, and billable 129 that determines whether the hours are billable or not.
In FIG. 6b, table Activity Labour contains a unique labour id 130, the name of the mechanic 132, the ticket number 134, the hours spent at various rates per hour (regular hour, half hour, overtime and travel hours) 136, as well as time spent at nonbillable activities 138.
In FIG. 6c, table Activity Parts provides information on the parts used for the elevator repair. The part id 140 is a unique identifier, and also includes a SKU number 142, OEM field 144, and the name and manufacturer of the part 146, 148, along with quantity of parts 150, description 152 and price 154.
In FIG. 7a, table Callbacks includes callback ID 156 for a unique record ID, device ID 158 to uniquely identify a device, a unique call code 160, call code 162, company callback ID 164, company ID 166, information regarding about the problem that occurred such as who entered the problem 168, the date, time and description of the problem 169, dispatch time 170, the call status 171 (including call status and call close time and date), mechanic arrive time 172, information regarding billable hours 174, as well as other information regarding updates of the system 176 such as who updated it or when the update occurred.
In FIG. 7b, table Callback Time contains time 178, callback ID 156, dispatch time 170, and mechanic arrive time 172 to determine the responsiveness of the mechanic's call.
In FIG. 7c, table Call Codes contains call code 162, a further call code 160 to map the service provider code with business partner code and uniformalize the data, company ID 166, and part name 182 to produce the call codes.
With reference to FIG. 8a, a sample of an XML string being transmitted between steps 60 and 65 is shown. In this example, the XML string transmits data on the building ID 185, which is a unique identifier of the building, row ID 186 of the table, the manufacturer ID 187 of the elevating device, the dispatcher ID 188, the car ID 189, a car name 190 for the elevating device, a date stamp 192, an event ID 193 which uniquely identifies the occurrence, along with the floor 195 where the incident occurred, and whether the event was confirmed 196.
In FIG. 8b, data conversion from step 65 to step 70 is depicted, wherein the data from the XML string is uniformalized into tables of the Datastore 70, in this example of the Building Events Table. The buildingid field is placed into the BuildingId field, the manufactureid into the ManufactureId field, and so on.
In FIG. 8c, the data types of the Building Events Table is shown. These fields in the table have data restrictions. For example, BuildingId is an integer, while RowId is a big integer, and CarId is a small integer and comment is a 255-character field that can hold various characters. In the data conversion process the data from the XML file is received and entered into the fields within the Datastore's 70 tables, under the restrictions of the various fields of the tables. Fields may be limited in different ways (such as varchar [127] or int [3]), and where the data does not fit, it is truncated or converted before being inserted into the database. For example, varchar [255] will be truncated to fit varchar [127], and a decimal number will be rounded to fit an integer data slot. In this way, the data is uniformalized into a single database. In an embodiment, inconsistencies of the field naming convention between the XML (representing the manufacturer's specification) and the tables of the Datastore 70 are resolved by means of a mapping table, wherein the names used by the XML incoming data are matched to the correct fields of the Datastore 70.
FIGS. 9a-c, 10a-b, 11a-b and 12a-c show further examples of XML data from Vendors that is used to encapsulate the maintenance history of an elevating device.
With uniformalization of maintenance and usage data, there is a single sign on. The end user can control callback, allowing the end user to notify different concerned parties, such as owners, service providers, consultants and building tenants, to avoid any unwanted events, as well as send reminders of any kind. Further, uniformalization allows the end user to view information from multiple service providers in one standard presentation, instead of multiple reports in multiple formats. The end user can access information at anytime, providing access to the most recent information on their equipment. Further, information is backed up in the business partner facility. Therefore, the end user can access historical data even after switching service providers. Additionally, backup of data within the business partner's facility provides protection to the end user in the event of a data failure. Having the multiple datasets uniformalized enables the business partner application to analyze datasets, show performance and deficiencies, and send out notifications to the concerned parties.
