Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a centralized monitoring device that is used in a monitoring system that performs communication between a plurality of terminal devices and a centralized monitoring device and monitors the operation status of each terminal device with the centralized monitoring device.
[0002]
[Prior art]
Conventionally, an intercom system has been used as a call system in an apartment house such as a condominium. The intercom system installs a house information board in each residence, and enables communication between the house information board and an interphone handset installed at a front door and a lobby intercom apparatus installed in a lobby.
[0003]
Furthermore, there is a centralized monitoring system using this call system. In this centralized monitoring system, a centralized monitoring device is installed in the manager's room, connected to the housing information board of each residence with a communication line, and a smoke detector, heat detector, gas Connect leak detection sensor, emergency call button, intrusion sensor, etc. The central monitoring device centrally monitors security information on each house information board.
[0004]
In this monitoring system, when an abnormal situation such as a fire occurs in a house, it is detected by the above various sensors, and a notification is sent from the house information panel to the centralized monitoring device. The manager determines the content of the abnormality by displaying the centralized monitoring device and takes necessary measures.
In this monitoring system, if there is a device abnormality in the housing information panel, it is not possible to report to the centralized monitoring device even if an abnormal situation occurs in the house. In order to cope with this, the centralized monitoring device automatically checks whether there is an equipment abnormality in each house information panel. For this purpose, the centralized monitoring device periodically sends a device confirmation signal to each housing information panel. Each house information panel returns a response signal when receiving this device confirmation signal, but cannot return a response signal when there is an abnormality in the device.
[0005]
In the centralized monitoring device, when a response signal is received after transmitting a device confirmation signal, it is determined that the house information panel is operating normally. It is determined that it has occurred. When a device abnormality is detected, the fact is displayed on the display unit, and the manager who sees it displays the necessary measures for repairing the home information board.
[0006]
[Problems to be solved by the invention]
In unoccupied houses in newly built apartments, the power breaker is turned off. Therefore, no power is supplied to the intercom device in the residence. For this reason, even if the centralized monitoring device transmits a device confirmation signal, the housing information panel does not return a response signal. Then, since the central monitoring apparatus does not receive a response signal, it determines that there is a device abnormality in the house information panel, and therefore displays an abnormality even though there is no device abnormality. Therefore, the manager must determine whether the residence in which the device abnormality is displayed is unoccupied or has been occupied.
[0007]
The present invention is composed of a plurality of terminal devices and a centralized monitoring device that communicates with these terminal devices, and the centralized monitoring device has a function of determining a terminal device that cannot communicate as an abnormal terminal device. The object is to provide an improved centralized monitoring device for use.
[0008]
[Means for Solving the Problems]
The present invention has been made to achieve the above object.
A centralized monitoring apparatus according to the present invention is a centralized monitoring apparatus that performs communication with a plurality of terminal devices, the communication unit that performs communication with the plurality of terminal devices, and hold registration for a predetermined terminal device. Means for performing communication with the terminal device by the communication means, and when the communication is impossible, the terminal device determines that there is no abnormality if the suspension registration is performed, and the suspension is performed. If the terminal device is not registered, the terminal device has a determining unit, and the communication unit intermittently performs communication with the plurality of terminal devices, When communication is possible during a predetermined time period such as at night, the hold registration is released for the terminal device.
[0009]
According to this centralized monitoring device, when a terminal device that has been registered on hold is put into an operating state, a response signal is returned in response to the device confirmation signal. When the centralized monitoring device receives the response signal, the centralized monitoring device cancels the pending registration for the terminal device. Thereby, the hold registration with respect to the terminal device can be canceled simply by bringing the terminal device into an operating state.
[0010]
When the terminal device that has been registered for suspension temporarily enters the operating state, each time the suspension is released, when the terminal device is deactivated again, the centralized monitoring device re-registers the suspension. Will have to do. On the other hand, in the present invention, the centralized monitoring device cancels the pending registration for the terminal device only when a response signal is returned to the terminal device that is registered for suspension in a predetermined time zone such as midnight. . Thereby, when a terminal device is temporarily made into an operation state, hold registration can be maintained.
[0011]

Various sensors such as a smoke detector, a heat detector, a gas leak detection sensor, an emergency call button, and an intrusion sensor are connected to the abnormal signal input means 23.
[0017]
The general operation of the call system shown in FIGS. 1 to 3 will be described.
As an intercom system, a resident in each residence 2 uses the interphone master unit 3 to make a call with a visitor at the entrance through the interphone slave unit 5, and a visitor in the lobby through the lobby intercom 7. Make a phone call. The main device 6 functions as a relay device for each interphone master unit 3 and the lobby interphone 7.
[0018]
As a monitoring system, the intercom master unit 3 in each residence 2 functions as a housing information board. When a fire, gas leak, intruder, or other emergency occurs, this is detected by a sensor or the like, and the intercom master unit 3 transmits an abnormal signal to the main device 6. The main device 6 functions as a centralized monitoring device. When the main device 6 receives the abnormality signal, the main unit 6 emits sound, light, or the like by the display means 14 to notify the manager that the abnormality has occurred. The manager takes necessary measures such as fire fighting and reporting to the police.
[0019]
The main device 6 periodically transmits a device confirmation signal to each intercom base unit 3 through the communication unit 12. When the intercom master unit 3 receives the device confirmation signal by the communication means 18, it returns a response signal. When the main device 6 receives this response signal, the main device 6 determines that there is no device abnormality in the intercom master unit 3. On the other hand, if a response signal is not returned, it is determined that a device abnormality has occurred in the interphone master unit 3 and the fact is displayed on the display means 14. Upon confirming this display, the manager takes necessary measures such as checking the interphone master unit 3. Thereby, even if a device abnormality occurs in the intercom base unit 3, it can be quickly repaired to restore the original function as a home information board.
[0020]
The operation as the interphone system and the operation as the monitoring system described above have been conventionally known, and various realization methods have been proposed. Therefore, detailed description here is omitted.
In this example, on-call registration is performed with respect to the intercom base unit 3 of the unoccupied residence 2 in the above telephone system.
[0021]
In the above call system, the interphone master unit 3 and the slave unit 5 are installed in each residence 2, but the power breaker is turned off in the unoccupied residence 2. Therefore, the intercom base unit 3 of the residence 2 is not operable because no power is supplied. For this reason, even if the main device 6 transmits a device confirmation signal to the interphone master unit 3, the interphone master unit 3 does not send back a response signal.
[0022]
Therefore, in this state, the main device 6 determines that a device abnormality has occurred in the interphone master unit 3, and displays an abnormality. On the other hand, the main device 6 of this example performs pending registration for the unoccupied residence 2 so that the interphone master unit 3 does not determine that the device is abnormal even if it does not send back a response signal. This hold registration is performed by the setting means 13 of the main device 6, and the interphone master unit 3 registered for hold is stored in the storage means 11.
[0023]
With reference to the flowchart of FIG. 4, an operation of checking the state of the device by the main device 6 will be described. The process of FIG. 4 is executed for each intercom base unit 3 at predetermined time intervals.
In step S1, a device confirmation signal is transmitted to one intercom base unit 3. In step S2, reception of a response signal is awaited. If no response signal is received, the process proceeds to step S3, where the storage means 11 is examined to determine whether or not the intercom master unit 3 is on hold. If the hold registration is made here, the state diagnosis is not performed for the interphone master unit 3, and the process is terminated.
[0024]
If it is determined in step S3 that the hold registration is not performed in the interphone master unit 3, the response signal is not returned even though the hold registration is not performed (N in step S2). 3 can be determined that a device abnormality has occurred. Therefore, in step S5, the device abnormality is displayed on the display means 14, and the process is terminated.
[0025]
If a response signal is received in step S2, the process proceeds to step S6, and it is determined whether or not the intercom master unit 3 is suspended and registered. In step S6, if the hold registration is not performed, it can be determined that the intercom base unit 3 is operating normally, and thus the process ends. If it is determined in step S6 that the registration is suspended, the process proceeds to step S82.
[0026]
The case where the process proceeds to step S82 is a case where a response signal is returned (Y in step S2) even though the hold registration has been made (Y in step S6). This is a case where the breaker is turned on and the intercom base unit 3 is in an operating state. In this situation, there is a case where the power breaker is temporarily turned on in order to visit the residence 2 or to visit the residence 2.
[0027]
In this example, in step S82, it is determined whether or not the current time is within a predetermined time zone. Here, the predetermined time zone is set to a time zone where a visitor or the like may not come, for example, a midnight time zone. If a resident enters the unoccupied house 2, the power breaker is turned on even at midnight. In this situation, the hold registration is canceled in step S9 and the process is terminated.
[0028]
As a result, when there is a resident in the unoccupied house 2, the hold is automatically released simply by turning on the power breaker of the house 2, so that it is possible to save time and prevent forgetting to release. In addition, when the state in which there is a response signal in the hold registration state is temporary, the power breaker of the residence 2 is turned off at the end of the tour before the predetermined time zone such as midnight. In the subsequent processing of FIG. 4, no response signal is received in step S2, and the pending registration is maintained.
[0029]
