  Next, the operation of the above embodiment will be described.

  3, 4, 5, 6, 7, and 8 are flowcharts showing the operation of the remote monitoring interface device 100 in the above embodiment.

  First, the power is turned on and initialized (S1). If the setting of the dip switch or the like is abnormal (S2), an error is displayed by the indicator lamp 25 (S3). If the setting is normal (S2), it is determined whether or not the connection to the fire receivers RE1, RE2,... Is completed (S4). If the connection is completed (S4), the transmitter 60 is instructed to make a call to the customer service center SC (S5).

  If the telephone line with the customer service center SC is established (S6), the interface device 100 informs the customer service center SC that the connection between the fire receivers RE1, RE2,. Notification is made (S7).

  Thereafter, a status request message is received from the customer service center SC (S8), and the requested information is transmitted to the customer service center SC (S9). For example, if nothing is done for 10 minutes, the telephone line is disconnected (S10).

  The above is the operation for starting state adjustment in the above embodiment.

  The interface device 100 is normally AC driven. If the AC power source is not driven due to disconnection, failure, or power failure of the AC adapter 52 (S21), the battery device 51 switches to driving (S22), and the battery 51 drives. If the customer service center SC is notified of the switching (S23), the remaining capacity of the battery 51 is checked as the power supply voltage (S31), and if the battery 51 has a sufficient voltage (S31), it is shown in FIG. Proceed to step S61.

  That is, if the cutoff switch 24 is off (S61), that is, if the cutoff switch 24 is set so as not to cut off transmission to the center SC, and the transfer to the center SC is being cut off (S62), the cutoff switch 24 is turned off. The inside is deleted (S63), a message blocking cancellation signal is transmitted to the customer service center SC (S64), the count T is cleared, and the process is stopped (S65). The determination of whether or not the message transfer is interrupted in steps S62 and S71 is not shown in detail, but can be determined by writing the state in a predetermined area of the memory built in the control means 10 and referring to this. It can also be indicated simply by turning the flag on and off.

  Further, if the shutoff switch 24 is on (S61) and the message transfer is not shutting off (S71), the shutting off is set (S72), a call is made to the customer service center SC (S73), and the customer service center SC is set. Is established (S74), a message blocking start signal is transmitted to the customer service center SC (S75), the telephone line is disconnected (S76), and the count T is started (S77). If the count T is incremented (S66), a call is made to the customer service center SC (S67), and if a telephone line is established with the customer service center SC (S68), the message is transferred to the customer service center SC. A cutoff alarm signal is transmitted, the telephone line is disconnected (S69), and if necessary, the count T is restarted (S70). Since the alarm is issued until the alarm state is recovered by restarting the count T, the alarm operation continues.

  In step S69, in the customer service center SC that has received the alarm, the monitoring staff can contact the customer side for confirmation and request the customer to release the block.

  In step S69, instead of transmitting an alarm to the customer service center SC, a buzzer may be provided in the interface device 100 so that the buzzer generates an alarm sound in the interface device 100.

  After the count T is restarted (S70), the process proceeds to step S41 shown in FIG. 4 to check the state change in the fire receivers RE1, RE2,... (S41). If the status of the fire receivers RE1, RE2,... Changes (S42) and the message blocking is being canceled (S43), that is, if it is not blocked, a call is made to the customer service center SC ( If a telephone line with the customer service center SC is established (S44), the customer service center SC is notified of changes in the status of the fire receivers RE1, RE2,... (S46), and the telephone line is connected. Disconnect (S47). Thereafter, the process proceeds to step S51 shown in FIG.

  In step S23 shown in FIG. 4, if it is not notified to the customer service center SC that the battery 51 has switched to driving, in step S24 shown in FIG. 5, a call is made to the customer service center SC, and the customer service center SC After the telephone line with the SC is established (S25), a “remote I / F power failure” indicating that the remote monitoring interface device 100 has failed is transmitted to the customer service center SC (S26), and the process goes to step S1. Return.

  If it is determined in step S31 shown in FIG. 4 that the power supply voltage level of the battery 51 is low and the remaining capacity is insufficient, a call is made to the customer service center SC in step S32 shown in FIG. If the telephone line with the service center SC is established (S33), the fact that the power supply voltage has been reduced is transmitted to the customer service center SC (S34). Then, the telephone line is disconnected (S35), communication with the fire receivers RE1, RE2,... Is stopped (S36), the power supply circuit 50 is turned off (S37), and the operation is performed so as not to make unnecessary movement. finish.

  After disconnecting the telephone line in step S47 shown in FIG. 4, in step S51 shown in FIG. 8, it is determined whether there is a request / control from the customer service center SC, and if there is a request / control from the customer service center SC. Then, it is determined whether or not the remote monitoring interface device 100 has released the message blocking (S52), and if the remote monitoring interface device 100 has not canceled the message blocking, the status request / control is determined. (S53).

  If it is status request / control (S53), a call is made to the customer service center SC (S54), and if a telephone line is established with the customer service center SC (S55), a request from the customer service center SC is made. The remote monitoring interface device 100 responds to the control (S56) and disconnects the telephone line (S57).

  The remote monitoring interface device 100 mainly receives a transmission signal from the fire receivers RE1, RE2,..., Converts the information into data using the received transmission signal, and uses a mobile phone communication network. Send data. During maintenance and inspection of the fire alarm facility, the interface device 100 can block communication on the data transmission side so that unnecessary information is not transmitted to the customer service center SC. If the cutoff switch 24 is turned on, remote monitoring is possible. Even if the interface device 100 receives a message from the fire receivers RE1, RE2,..., Data is not transmitted to the network NW.

  Further, the remote monitoring interface device 100 has its own power supply circuit 50, and the control means 10 monitors the supply voltage of the power supply circuit 50. When the monitored voltage drops, the remote monitoring interface device 100 supplies the power to the customer service center SC. After transmitting data indicating that the power supply of the circuit 50 has dropped, the operation (the operation of the remote monitoring interface device 100) is stopped. As a result, even if the voltage of the unique power supply circuit 50 provided in the remote monitoring interface device 100 decreases, erroneous data transmission to the customer service center SC based on unstable operation is not performed.

  In other words, in the first embodiment, the interface device 100 is provided with a timer for measuring a predetermined time (for example, 1 hour), and when the time during which the message transmission is cut off passes the predetermined time from the interface device 100 to the customer service center. It is a device that transmits a message breaking alarm signal to the SC. Upon receipt of this message cutoff alarm signal, the customer service center SC can send a confirmation message (telephone etc.) to the customer equipment CL about the state of the cutoff switch 24.

  As a modified example of the first embodiment, an alarm unit such as a buzzer or a flashlight controlled by the control unit 10 is added to the interface apparatus 100, and after a predetermined time has elapsed by a timer that measures a predetermined time, the interface apparatus 100 An alarm sound for releasing the interruption may be generated. As a result, it is completed in the customer-side equipment CL, and the person concerned confirms the state of the cutoff switch 24.

  In such a modification of the first embodiment, since the interface device 100 includes the alarm unit, there is a demerit that the number of parts is increased and the cost is increased. Can work directly with workers. That is, when the interface device 100 is sounded, the alarm is given at a sound level in the customer equipment CL, so that it may be understood as noise. In that respect, the alarm by the flashlight does not disturb the surroundings.

  Further, as a second modification of the first embodiment, instead of the counter T serving as the timer in the first embodiment, an input unit for the time when the input is detected by the control means 10 is added to the interface device 100, and a test described later is performed. It is also possible to set a predetermined time such as the end time. Then, after a predetermined time elapses due to the passage of time, a transfer interruption alarm signal can be transmitted from the interface device 100 to the customer service center SC as in the first embodiment, and a modification of the first embodiment. As an example, an alarm sound for releasing the cutoff can be generated from the interface device 100. The relationship between the transmission interruption alarm signal and the alarm sound for releasing the interruption is the same as that of the timer.

Since the time input for setting the predetermined time is not a simple switch on / off, the interface device 100 needs to devise an input unit. However, at a predetermined time based on the end time, an alarm that matches the test work time is possible. Furthermore, by providing an input unit in the interface device 100, it is possible to input a predetermined time simultaneously with the operation of the cutoff switch 24. Furthermore, by providing an alarm unit in the interface device 100, it can be completed with the customer side equipment CL.

  FIG. 9 is a flowchart showing the relationship between the operation of the customer-side facility CL and the operation of the customer service center SC according to the second embodiment of the present invention.

  The configuration of the second embodiment is the same as the configuration in the remote monitoring system RM1 that is the first embodiment.

  First, in the customer side equipment CL, the cutoff switch 24 in the remote monitoring interface device 100 is turned on (S81), and “transition interruption is in progress” is transmitted to the customer service center SC. The data is transmitted to the center SC (S82). At the same time, although not shown in detail, the control means 10 of the remote monitoring interface device 100 holds “blocking” by setting a state and a flag at a predetermined position in the memory. At the customer service center SC, the message “Transfer blocked” is received (S83), the duration is measured as a timer function (S84), and when a predetermined time elapses, an alarm is issued (S85). The facility CL is contacted for confirmation (S86), and the customer facility CL turns off the cutoff switch 24 based on the contact (S87).

  In the second embodiment, the customer service center SC may measure the duration of message blocking, warn after a predetermined time has elapsed, and contact the customer service center SC for confirmation.

  In the second embodiment, since the predetermined time is counted on the customer service center SC side, it is possible to warn the status of the message transfer interruption without providing a special function in the interface device 100.

  Further, as a modification of the second embodiment, a message breaking alarm signal may be transmitted from the service center SC to the interface device 100 after a predetermined time has elapsed. It is necessary to add an alarm unit such as a buzzer or a flashlight and to sound an alarm sound for releasing the interruption from the interface device 100. Thereby, the person concerned confirms the state of the cutoff switch 24 in the customer side equipment CL.

  In such a modification of the second embodiment, the interface device 100 includes a simple alarm unit, and the work at the customer service center SC that needs to work centrally can be reduced.

  FIG. 10 is a flowchart showing the relationship among the operation of the customer-side facility CL, the operation of the customer support DB server SV2, and the operation of the remote maintenance client MC1 regarding the third embodiment of the present invention.

  The configuration of the third embodiment is the same as the configuration in the remote monitoring system RM1 of the first embodiment.

  Similarly to steps S81, S82, and S83 in the flowchart of FIG. 9 of the second embodiment, the customer side equipment CL turns on the cutoff switch 24 (S91), and sets the message cutoff start signal as “transmission cutoff”. The message is transmitted to the customer support DB server SV2 in the center SC (S92), and the customer support DB server SV2 receives “transmission cut off” via the remote monitoring server SV1 (S93), and captures the end time based on it. A request is made to the remote maintenance client MC1 (S94), and the remote maintenance client MC1 transmits the end time (expected required time) to the customer support DB server SV2 (S95).

  This end time is the scheduled end time of the test operation of the fire alarm facility in the customer side facility CL, and is set by the service engineer (SE) who works on site. The input of the end time from the SE is collected by the remote maintenance client MC1 via the portable information terminal. Therefore, in order for the remote maintenance client MC1 to transmit the end time to the customer support DB server SV2 in step S95, it is necessary to receive the end time from the service engineer's terminal at the timing before step S95 (S101). There is.

  In the customer support DB server SV2, an alarm time is set (S96), an alarm is issued at the set alarm time (S97), and if the alarm is not released (S98), the customer service center SC makes a telephone call or the like. Confirmation is communicated to the facility CL (S99), and the customer facility CL turns off the cutoff switch 24 based on the communication (S100).

  The remote maintenance client MC1 receives the required time required for the work such as the test from the service engineer (S101), and uses the end time specified from the estimated required time as the end time in step S95. Good.

  As described above, the third embodiment is a case where the setting of the message blocking is a normal test, and an alarm may be issued after that by setting the time limit in anticipation of the end time.

  In the third embodiment, since the customer service center SC issues an alarm at a predetermined time corresponding to the end time of the work, it is possible to give an alarm of the transfer blocking state regardless of the size of the property, and the interface device 100 Even if a special function is not provided in the system, it is possible to warn of the status of the message transfer interruption.

  Further, as a modified example of the third embodiment, as in the modified example of the second embodiment, after the elapse of a predetermined time, a message blocking alarm signal may be transmitted from the service center SC to the interface device 100. Sometimes, it is necessary to further add an alarm unit such as a buzzer or a flashlight controlled by the control means 10 to sound an alarm sound for releasing the interruption from the interface device 100. Thereby, the person concerned confirms the state of the cutoff switch 24 in the customer side equipment CL. Even in the modification of the third embodiment, the interface device 100 includes a simple alarm unit, and the work at the customer service center SC that needs to work centrally can be reduced.

In each of the above embodiments, when measuring a predetermined time as a timer, the predetermined time may be selected and set stepwise such as small, medium, and large. The difference in work time depending on the size of the property can be dealt with even if there is no numerical input like time input.
