  However, in the housing complex intercom system of the above-mentioned conventional example, even when an emergency situation such as an earthquake alarm occurs during the transmission of the state recovery signal (reset signal), the earthquake information is received. The earthquake recovery information cannot be received during the state recovery signal reception time (for example, 5 seconds), and the beginning of the alarm content is missing (cut out), and there is a possibility that information with high urgency cannot be received sufficiently. .

  The present invention was made in order to solve the above-mentioned difficulties, and by receiving emergency information such as earthquake information at an early stage even while receiving a state recovery signal, the alarm is severely interrupted. It is an object to provide an intercom system for collective housing that can reduce noise.

The first aspect of the apartment house intercom system of the present invention is installed in an apartment entrance to be set up at an entrance of an apartment house for a visitor to call a resident and establish a call, respectively, and to a plurality of units in the apartment house. The resident who responds to the call from the visitor sends / receives signals between the master unit for establishing a call and each terminal of the collective entrance unit and the master unit for the call and controls the call. For each of the terminals. The controller includes a main control circuit that intermittently generates a state recovery signal for recovering each of the collective entrance unit and the room base unit in an abnormal state to a normal state. The state recovery signal that is intermittently transmitted from the main control circuit of the controller is valid when the own terminal is in an abnormal state, and the normal state is restored from the abnormal state. State recovery / holding circuit to hold the normal state as if the signal is invalid, and the presence / absence of the received signal transmitted from the controller is detected, and the operation based on the received signal when the presence of the received signal is detected And a terminal control circuit for performing control. The controller is connected to an earthquake early warning receiver for receiving earthquake information transmitted from an external organization via an external network, and is transmitted intermittently. When earthquake information is detected while transmission of the state recovery signal is stopped, transmission of the subsequent state recovery signal is stopped to return to the standby state .

In addition, the second aspect of the apartment house intercom system according to the present invention includes an apartment unit installed at the apartment entrance of the apartment house for a visitor to call a resident or a manager to establish a call, and a plurality of apartment houses. Residents responding to calls from visitors who have been installed in each of the apartments in the apartment will establish a call, and will also be installed in the living room master unit for the resident to call the manager and establish the call, and in the apartment room management room Signals are sent and received between the control room master unit for the manager to establish a call in response to a call from a visitor or resident, and each terminal of the collective entrance unit, living room base unit, and control room base unit. And a control device for controlling calls and calls, and the control device is a state recovery signal for recovering the collective entrance device, the living room base unit, and the management room base unit that are in an abnormal state to a normal state. Intermittent The main control circuit is generated in each terminal, and each terminal is restored from the abnormal state to the normal state by assuming that the state recovery signal intermittently transmitted from the main control circuit of the controller is valid when the terminal is in an abnormal state. When the terminal is in a normal state, the state recovery signal is invalid and the state recovery / holding circuit for holding the normal state is detected, and the presence / absence of the reception signal transmitted from the controller is detected. And a terminal control circuit for controlling the operation based on the received signal when the presence of the earthquake is detected, and the controller receives an earthquake early warning receiver for receiving earthquake information sent from an external organization via an external network There are connected, when detecting the seismic information during the transmission of the intermittently transmitted come state restoration signal is stopped, and the transmission of the subsequent state restoration signal to return to the standby state stops And wherein the door.

  Further, according to a third aspect of the apartment house intercom system of the present invention, in the first or second aspect, the terminal control circuit of the terminal in a normal state capable of recognizing the state restoration signal when the state restoration signal is sent is the state. By sending the recovery avoidance signal to the state recovery / holding circuit, recovery is avoided, and the terminal control circuit of the terminal in an abnormal state where the state recovery signal cannot be recognized sends the state recovery avoidance signal to the state recovery / holding circuit It is characterized by being restored by not doing.

  According to such an intercom system for an apartment house, even if an emergency such as an earthquake alarm occurs during transmission of a state recovery signal, the earthquake alarm signal is detected between the state recovery signals transmitted intermittently. It is possible to reduce the head-out state of an alarm with a high degree of urgency.

  The operation of the intercom system for an apartment house constructed as described above will be described below.

  As in the conventional example, the controller 4 is managed by various operations in the operation units 11, 21, 31 of the management room master unit 1, the collective entrance unit 2, and the plurality of living room master units 3a, 3b, 3c,. Various data signals transmitted through the room connection main line L1, the collective entrance connection main line L2, and the room connection main line L3 are transmitted and received to control call notifications and calls.

  Next, when the main control circuit 44 of the controller 4 is shifted from the standby state to the setting detection state periodically or by an appropriate operation of the setting unit 43 by an operator or the like who maintains and inspects the apartment house, A state recovery signal S1 for resetting the terminal in the abnormal state to recover the normal state is output.

  This state restoration signal S1 is sent to the communication circuit 10 of the control room base unit 1 and the collective via the control room connection main line L1, the collective entrance connection main line L2, and the living room connection main line L3 connected to the communication circuits 40, 41 and 42, respectively. It is transmitted to each communication circuit 30 of the communication circuit 20 of the entrance machine 2 and the plurality of room master units 3a, 3b, 3c,.

  Here, among the management room master unit 1, the collective entrance unit 2, and the plurality of living room base units 3 a, 3 b, 3 c,... That form a plurality of terminals, for example, the management room base unit 1 and the living room base unit 3 a are normal. And the normal state is detected by the terminal control circuits 13 and 33, and the collective entrance machine 2 and the other living room master units 3b, 3c,... In the case where an abnormal state is detected in each terminal control circuit 33 of the circuit 23, the room masters 3b, 3c,..., The management room parent of the management room master 1 and the room master 3a in the normal state. The state restoration signal S1 transmitted to the communication circuit 10 of the machine 1 is input to the terminal control circuit 13 and the state restoration / holding circuit 14 respectively, and the terminal control circuit 13 in the normal state recognizes the inputted state restoration signal S1. State recovery avoidance signal S to avoid reset The output to the state recovery and hold circuit 14. As a result, the terminal control circuit 13 is not reset and maintains a normal state.

  Similarly, the state restoration signal S1 transmitted to the communication circuit 30 of the living room master unit 3a is inputted to the terminal control circuit 33 and the state restoration / holding circuit 34, respectively, and the normal state terminal control circuit 33 is inputted to the state restoration signal. A state restoration avoidance signal S2 for recognizing S1 and avoiding reset is output to the state restoration / holding circuit 34. As a result, the terminal control circuit 33 is not reset and maintains a normal state.

  On the other hand, the state restoration signal S1 transmitted to the communication circuits 20 of the collective entrance 2 in the abnormal state and the communication circuits 30 of the room master units 3b, 3c,... Is sent to the terminal control circuit 23 and the state restoration / holding circuit 24. And input to each terminal control circuit 33 and each state restoration / holding circuit 34. Here, since the terminal control circuit 23 and each terminal control circuit 33 in an abnormal state cannot recognize the inputted state restoration signal S1, the state restoration avoidance signal as described above is output to the state restoration / holding circuits 24 and 34. There is no. As a result, the terminal control circuit 23 of the collective entrance 2 and the terminal control circuits 33 of the living room master units 3b, 3c,... Are reset from the state restoration / holding circuits 24, 34 and restored to the normal state. Is done.

  In such an apartment intercom system of the present invention, the state restoration signal in the above embodiment will be described in detail.

  FIG. 2 is a diagram showing the transmission state of the state restoration signal, FIG. 2 (a) shows the transmission state of the conventional apartment house intercom system, and FIG. 2 (b) shows the transmission state of the apartment house intercom system of the present invention. It is a representation.

  As shown in FIG. 2A, the state recovery signal transmission state of the conventional apartment house intercom system continues to transmit the state recovery signal for a certain period of time (for example, 5 seconds). Even if urgent information such as is transmitted, a signal from another cannot be received while the state restoration signal is transmitted. Therefore, only information after the transmission of the state restoration signal is available can be obtained. For example, a situation occurs in which the information is cut off for 5 seconds.

  On the other hand, in the apartment house intercom system of the present invention, as shown in FIG. 2B, for example, a state recovery signal is transmitted for 0.9 seconds, and the transmission is repeatedly stopped for the next 0.1 seconds, The state recovery signal is transmitted intermittently.

  In such a transmission state, signals from other terminals, emergency information, etc. can be detected within 0.1 seconds when transmission of the state recovery signal is stopped, and such signals and information are detected. In such a case, the transmission of the subsequent state recovery signal is stopped to return to the standby state. As a result, it is possible to notify an emergency earthquake bulletin after 1 second at the longest.

  As described above, there is a time lag in notifying information for a maximum of one second, but this time lag hardly affects broadcasting. Further, the transmission interval of the state recovery signal need not be limited to the example of 0.9 second transmission and 0.1 second stop as described above. For example, 0.5 second transmission, 0.1 second stop, etc. Good. That is, if the interval of intermittent transmission is short, urgent information or the like can be notified in a state where the time lag is as short as possible and the head is not cut off. Therefore, the transmission interval of the state restoration signal can be appropriately set appropriately according to the situation of the apartment house intercom system.

  By the way, each terminal can be set to recognize that it is a state restoration signal if the signals transmitted intermittently can be detected for a total of 3 seconds, for example. However, in this case as well, it can be appropriately changed depending on the situation of the apartment house intercom system.

  When the state restoration signal is not received in the multi-dwelling house intercom system of the present invention having the above configuration and operation, the earthquake information receiver 7 receives the earthquake information sent from the external organization 5 via the external network 6. If it receives by, the earthquake warning signal for alerting | reporting an earthquake warning from a controller will be transmitted to each terminal. In each terminal, the display units 12, 22, and 32 are driven based on the earthquake alarm signal to display that an earthquake has occurred, and control is performed to drive a notification unit such as a speaker (not shown). For example, a broadcast such as “An earthquake is generated. An earthquake with a seismic intensity of 5 will occur after about 6 seconds” is transmitted from the speaker.

  On the other hand, when the state restoration signal is received, when the earthquake early warning receiver 7 receives the earthquake information, the controller transmits an earthquake warning signal for informing the earthquake warning to each terminal. Each terminal receives the state restoration signal, but the terminal control circuits 13, 23, 33 check whether other signals have been received within 0.1 seconds between the state restoration signals transmitted intermittently. In this case, it is possible to detect that an earthquake warning signal has been received.

  When the earthquake warning signal is detected, the terminal control circuits 13, 23 and 33 stop receiving the state restoration signal and preferentially receive the detected earthquake warning signal. Accordingly, the display units 12, 22, and 32 are driven based on the earthquake warning signal to display that the earthquake has occurred, and the notification unit such as a speaker is driven to report the earthquake broadcast from the speaker. be able to.

It is an example of the block diagram which shows the structure of the apartment house intercom system of this invention. It is a figure showing the transmission state of the state recovery signal of the apartment house intercom system of this invention.
