Description

  The present invention relates to an emergency call monitoring device that monitors and controls the state and abnormality of an elevator and building equipment at a remote location via a telephone line.

  A conventional emergency call monitoring device transmits a modem signal, a PB signal, etc. between an emergency call device provided on an elevator or building facility side (hereinafter referred to as a building side) and an emergency call device provided on a remote center side. Use it to send and receive data and remotely monitor and control. In order to periodically check that there is no abnormality in the building side emergency call device and telephone line, the building side emergency call device sends a call to the center side emergency call device at regular intervals (hereinafter referred to as “regular notification”). . Scheduled alerts can be confirmed even if the center emergency call device does not receive calls using the number display function. In addition, there exists a thing shown in patent document 1 as a similar remote monitoring apparatus.

JP-A-11-112690

  In the conventional emergency call system as described above, a communication fee is charged each time a regular alert is issued. In addition, even if the number display function is used and a regular notification is made when there is no incoming call, there is a problem that an abnormality in the data communication system in the emergency call device cannot be confirmed.

  The present invention has been made to solve the above-described problems. The incoming call is received once every several times of regular notification, and it is confirmed that there is no abnormality in the data communication system by performing data communication. It is another object of the present invention to make it possible to identify scheduled reports and reports from the building emergency call device (hereinafter referred to as “normal reports”) due to abnormalities in the building equipment and the like.

  The emergency call monitoring device according to the present invention connects a building-side emergency call device installed on the building side and a center-side emergency call device installed on the center side with a telephone line, and is used for line fault inspection from the building-side emergency call device. The center side emergency call device uses the number of calls for the above notifications to notify the center side through the telephone line of regular alerts for the status of elevators and equipment in the building and normal alerts for notifying abnormalities. A detector, a telephone number recognizer, a number notification call counter that counts the number of scheduled notifications, and the output of the call number detector, the telephone number recognizer, and the number notification call counter A central processing unit is provided to control the number and type of notification, so that a normal notification is received and a regular notification is received once every plural times.

  According to the emergency call monitoring device according to the present invention, the number of calls is changed between the regular alert and the normal alert, and the center emergency alert device can detect the number of calls. In addition, the number of scheduled reports can be counted, and once every few scheduled reports are received, it is possible to check for abnormalities in the data communication system. There is an effect that can be done.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing an emergency call monitoring apparatus according to Embodiment 1 of the present invention. This emergency call monitoring device comprises a center side emergency call device 1 and a building side emergency call device 2 connected by a public telephone network 3 which is a telephone line. Although the building-side emergency call device 2 is not shown in the figure, it has a number of built-in equipment monitoring devices, and functions to notify the center-side emergency call device 1 via the public telephone network 3 of the state or abnormality of the elevator or building equipment. Have The center side emergency call device 1 includes a network control device 5 for connection to the public telephone network 3, a call number detector 6 that counts the number of calls when a call is received from the building side emergency call device 2, and a number display service. Is used to control the telephone number recognizer 7 for recognizing the telephone number of the other party, the number notification call counter 8 for counting the number of calls received by the number notification, the data communication modem 9, and the signals 5-9. A central processing unit 4 is provided.

  Next, the operation will be described. When the building side emergency call device 2 detects the state or abnormality of the building side elevator or building equipment, the building side emergency call device 2 notifies the center side emergency call device 1 through the public telephone network 3. The network control device 5 detects the notification and transmits the number of calls and the other party's telephone number to the call number detector 6 and the telephone number recognizer 7, respectively. The telephone number recognizing device 7 recognizes the telephone number of the other party, thereby specifying which emergency call device of which building is notified. The building-side emergency alert device 2 also performs regular alerts that emit a signal at regular time intervals, but with a regular number of short calls (for example, three times) and a regular number of calls with a long number of calls (for example, four or more). The center side emergency call device 1 is notified.

  The number-of-calls detector 6 of the center-side emergency call device 1 counts the number of calls of the building-side emergency call device 2 and transmits it to the central processing unit 4. If the number of calls is short, the central processing unit 4 determines that it is a regular alert, and if the number of calls is more than that, it determines that it is a regular alert. When the number of calls is short, the central processing unit 4 determines that the alarm is scheduled, and increments the value of the number notification call counter 8 by one. When the counter value of the number notification call counter 8 counts a certain set number of times (for example, five times), the center side emergency call device 1 receives an incoming call, checks the communication system for abnormality, and has the number notification call counter 8 If it is less than the set value (for example, 5 times), only the scheduled notification from the building emergency call device 2 is performed without receiving a call.

  As described above, according to the present invention, when the call is made from the building-side emergency call device, the center-side emergency call device recognizes the other party's telephone number so that the number of calls can be counted. By recognizing the number of notifications from the notification device and receiving a fixed number of notifications once every several times, it is possible to confirm an abnormality in the communication system at a low communication fee. In addition, the number of calls is counted, and it is now possible to recognize whether it is scheduled or normal, depending on the number of counts. Can do.

  The present invention can be applied to a remote monitoring device that monitors a large number of building facilities and equipment.

It is a block diagram which shows the emergency call monitoring apparatus which concerns on Embodiment 1 of this invention.
