In FIG. 4, reference numeral 104 denotes a bus.

  Next, the operation of the remote monitoring system of the present invention will be described.

  First, at the time of system start-up, the service function unit OAS of the gateway 8 detects the equipment 3 (3a1, 3a2, 3b, 3c) equipped with the module part MOS connected to the LAN 6 and performs the processing for detecting the equipment 3 on the LAN 6 ( 3a1, 3a2, 3b, 3c) information necessary for network communication such as IP addresses is acquired. After the connection processing, the module part MOS of each equipment 3 (3a1, 3a2, 3b, 3c) sends the OID of the equipment side object on its module part MOS to the service function part OAS of the gateway 8 and below All the combinations of IID information of the interface are sent to the service function unit OAS of the gateway 8.

  On the other hand, the service function unit OAS of the gateway 8 receives the combination information of the OID and IID of the facility-side object received from the facility device 3 (3a1, 3a2, 3b, 3c) and the facility device 3 (3a1, 3a2, 3b, 3c) is associated with an IP address that is an identifier on network communication (TCP / IP base) and is stored and held in advance in the equipment connection information table. The information on the correspondence relationship between the stored combination information and the IP address is updated according to the increase / decrease of the equipment 3.

  Further, the gateway 8 performs processing for notifying the client terminal 10a connected to the subordinate LAN 6 of the combination information of the OID of the server-side object of the service function unit OAS and the IID of the interface. This process is performed each time the combination information of the OID of the server-side object and the IID of the interface of the service function unit OAS is updated.

  It should be noted that the gateway 8 may also send information on the OID of the equipment object of the equipment 3 (3a1, 3a2, 3b, 3c) and the IID of the interface below it.

  Further, the gateway 8 is a server equipped with the service function unit OAS on the Internet 9, and in FIG. 1, the equipment side object OID of the equipment 3 (3a1, 3a2, 3b, 3c) under its control with respect to the center server 12 and the interface below it. A process of sending IID combination information is performed. This process is performed every time the combination information of the OID and IID of the facility-side object received from the facility equipment 3 (3a1, 3a2, 3b, 3c) under its control is updated.

  Furthermore, the gateway 8 sends the OID of the server-side object of the service function unit OAS and the IID of the interface to the center server 12 in advance and also sends its own IP address. The center server 12 that has received the information sends the OID of the server-side object of the gateway 8 and the IID of the interface of the gateway 8 to the client terminal 10b, and associates the server-side object with the IP address of the gateway 8. Hold the attached routing table.

An operation of receiving the monitoring service of the equipment 6 from the client terminal 10a or 10b in the system in a state where the system is constructed in this way will be described based on the embodiment.
(Embodiment 1)
This embodiment relates to a service for notifying the client terminal 10a (or 10b) whenever there is a change in the lighting state of the luminaire 1a monitored and controlled by the centralized controller 3a1, as shown in FIG. The object included in the module unit MOS of the information processing unit 33 of the centralized controller 3a1 has an interface that defines event information indicating the occurrence of a change in the lighting state and is given "Illumination" as an IID. The one with the corresponding “lighting equipment” OID is used.

  That is, after there is an execution request for an object using the OID “lighting fixture” and the IID “lighting”, the information processing unit 33 sends the lighting fixture 1a from the functional unit 30 of the centralized controller 3a1 via the module MOS. Each time the current lighting state changes, the information is acquired as event information, and the acquired event information is sent to the requesting side (gateway 8 in the illustrated example).

  On the other hand, for the server-side object that the service function unit OAS of the gateway 8 has, an execution request is issued to the central control controller 3a1 in advance by using an OID “lighting fixture” and an IID “lighting”. In addition to having an acquisition function for acquiring and managing event information from the control controller 3a1, an interface having an event information defined and attached with an IID "illumination" and having an OID "XXX" is used.

  When the execution request using the OID and IID for the server side object is the client terminal 10a (or 10b), the service function unit OAS of the gateway 8 thereafter receives the lighting apparatus as event information from the centralized controller 3a1. When there is a change in the monitoring information of the lighting state 1a, a process for notifying the monitoring information to the client terminal 10a (or 10b) when the following predetermined condition is satisfied is performed.

  That is, the server-side object of the service function unit OAS receives monitoring information as event information from the centralized controller 3a1 every time a change in the lighting state of the lighting fixture 1a occurs from the centralized controller 3a1, that is, every time an event occurs. The service function unit OAS of the gateway 8 is sent to the service function unit OAS, and each time the monitoring information is received, the monitoring function stores the monitoring information in the storage unit and discards the monitoring information held first, and monitoring When the monitoring information is held until a certain time (chattering avoidance period = predetermined condition) has elapsed (satisfied) after the time count is started after the information is held, the lighting fixture 1a is based on the monitoring information. It is converted into monitoring information (event information) of “lighting state” and the monitoring information is converted into a client terminal Is programmed to perform a process for notifying to 0a (or 10b).

  Therefore, if the client terminal 10a (or 10b) requests the service function unit OAS of the gateway 8 to execute the server-side object using the IID “lighting” and the OID of the server-side object, the lighting apparatus It is possible to enjoy a service of notifying every time a change in the lighting state of 1a occurs.

  Here, even if there is a change in the lighting state of the luminaire 1a, the client terminal 10a (or 10b) is not immediately notified for the following reason.

  That is, when the client terminal 10a is notified every time a change occurs in the lighting state of the lighting fixture 1a, if chattering occurs when the lighting fixture 1a is operated with a manual switch or the like, the chattering change state is notified. However, in this embodiment, it is possible to notify the client terminal 10a of the monitoring information (event information) of the stable “lighting state” without being affected by the chattering operation of the lighting fixture 1a. There are advantages.

  In the case of the present embodiment, the central control controller 3a1 that is equipment does not have a program for processing chattering, and the monitoring information received from the central control controller 3a1 is processed and chattered by the client terminal 10a (or 10b). The client terminal 10a (or 10b) can be monitored without being affected by chattering without providing a program that cancels the program, that is, without changing the program of the centralized controller 3a1 and the client terminal 10a (or 10b). Service can be provided.

  If a similar execution request is made from the client terminal 10b on the Internet 9 to the server-side object of the gateway 8, the center server 12 mediates, and the execution request is transmitted to the gateway 8 via the Internet 9. The same processing is performed.

  When monitoring information associated with the occurrence of an event is received from the centralized controller 1a as an application of the service function unit OAS, a certain time (chattering avoidance period) starts to be counted, and the content of the monitoring information when the certain time elapses is constant. “Lighting information” of the monitoring information at the time when a certain time has passed (or the monitoring information that became the starting point of the certain time count) when the condition that the content of the monitoring information that has become the starting point of the time count has not changed is satisfied. Even if the event information is converted into event information and the event information is notified to the client terminal 10a (or 10b), the influence of chattering can be avoided as in the case described above. Furthermore, even if the monitoring information that is the starting point of the certain time count is different from the monitoring information content when the certain time has elapsed, the monitoring information content when the certain time has elapsed is different from the monitoring information content before the counting start point. If so, the client terminal 10a or 10b is notified of the contents of the monitoring information when a certain time has elapsed. Thus, even if various events occur during a certain time (for example, 10 seconds), the troublesome state display due to chattering or the like is reduced. That is, it is possible to notify only the final state of a series of operations.

By notifying only the final state of a series of operations, traffic for notification can be reduced.
(Embodiment 2)
In the present embodiment, information based on the state of the entrance electric lock 1c1 controlled and monitored by the centralized controller 3a1 and the state of the gate electric lock 1c2 controlled and monitored by the centralized controller 3a2 is transmitted to the client terminal 10a. (Or 10b).

  In the present embodiment, as shown in FIG. 6, the module MOS of the information processing unit 33 of the centralized controller 3a1 is a facility-side object with an OID “entrance”, and the information processing unit 33 of the centralized controller 3a2. The module part MOS has equipment-side objects each having an OID of “gate”, and defines event information corresponding to “applied / unlocked” for each equipment-side object, and an IID called “electric lock”. When there is a change in the lock / unlock state of the electric lock 1c from the start of operation, that is, when an event occurs, event information indicating the state is notified to the service function unit OAS of the gateway 8. It is like that.

  On the other hand, the service function unit OAS of the gateway 8 indicates the state of the electric lock 1c of “gate” and “entrance” based on the event information indicating the change in the lock / unlock state of the electric lock 1c from the centralized controller 3a1. It has an acquisition function for acquisition management, and has an IID called “electric lock 1”, an interface that defines a variable corresponding to “locked state”, and an IID called “going out / going home”, and event information of returning home And an interface that defines event information of going out, and has a server-side object with “XXX” added as an OID.

  For example, when an execution request is issued from the client terminal 10a using the OID “XXX” and the IID “electric lock”, the server-side object receives the current “gate” electrical information acquired by the acquisition function described above. If the state of the lock 1c and the state of the electric lock 1c of the “entrance” are both locked (= predetermined condition <logical product condition>), the “locked state based on event information managed by the acquisition function” Is obtained when an execution request is made using an OID of “XXX” and an IID of “going out / going home”. In the state of the electric lock 1c acquired by the means, the state change of the electric lock 1c of the “gate” occurs, and the electric lock 1c of the “gate” becomes “unlocked”. When the predetermined condition that the electric lock 1c is “unlocked” is satisfied, it is converted into event information “home” based on the event information and the event information is notified to the client terminal 10a. On the contrary, in the state of the electric lock 1c acquired by the acquisition function, the state change of the electric lock 1c of the “entrance” occurs, and the electric lock 1c of the “entrance” becomes “locked”, and the electric lock of the “gate” When a predetermined condition that 1c is in the “locked state” is satisfied, it is programmed to notify the client terminal 10a of event information “going out” based on the event information. That is, the contents of the event information, which is the monitoring information notified by the client terminal 10a, are changed according to the order of the state change of the electric locks 1c1 and 1c2 (time series condition = predetermined condition).

  Thus, on the client terminal 10a side that made the execution request, the current state of the electric lock 1c1 of the “entrance” and the state of the electric lock 1c2 of the “gate” can be known, and the “home” and “going out” "Is also known in real time.

  That is, in the present embodiment, the client terminal can be used without changing the original program for monitoring and controlling the electric locks 1c1 and 1c2 of the central control controllers 3a1 and 3a2 or changing the program at the client terminal 10a (or 10b). It is possible to provide a service for notifying the state of the electric locks 1c and 1c2 and a service for notifying the “returning home” and “going out” of the householder to 10a (or 10b). In addition, since only the monitoring information indicating the result is notified at the client terminal 10a (10b), the server such as the gateway 8 or the center server 12 equipped with the service function unit OAS and the client terminals 10a and 10b There will be no increase in traffic.

  If a similar execution request is made from the client terminal 10b on the Internet 9 to the server-side object of the gateway 8, the center server 12 mediates, and the execution request is transmitted to the gateway 8 via the Internet 9. The same processing is performed.

  By the way, in the second embodiment, one server side object is provided with two interfaces each defining different information, a different IID is combined under the OID of the object, and the server is obtained by combining the OID and one of the IIDs. The execution request of the side object is made, but each server side object has an interface defining each information, and the combination of the OID of each server side object and the IID of the interface below it Each server-side object requested to be executed may be associated with each facility-side object. This makes it possible to develop further various services.

  In the second embodiment, event information such as “going home” or “going out” is notified to the client terminal 10a (or 10b) by changing the state of the electric locks 1c1 and 1c2 of the interface. ”And“ entrance ”are provided with human sensors and security sensors for detecting the opening and closing of the windows, and a change in the state of these sensors is notified from the alarm monitoring device 3b to the gateway 8 as event information.
