Next, the room units J1 to Jn and the management control panel S
An outline of the operation of the abnormality processing function between M1 and SM2 will be described. Hereinafter, one of the room units J1 to Jn is denoted by J, and one of the management control panels SM1 and SM2 is denoted by S.
Let it be denoted by M. The abnormal processing here is fire,
Disaster prevention processing such as gas leakage and crime prevention, call processing for calls such as baths and toilets, and failure processing such as disconnection of disaster prevention devices, disconnection of sensors, and transmission abnormalities. When performing the abnormality processing, when the abnormality detector group UD in each room detects an abnormality, the room unit J in each room issues an emergency polling request to the management control panel SM. The management control panel SM that has received the urgent polling request sends urgent polling data to the room units J in all rooms.

The room unit J of the room that has detected the abnormality notifies the management control panel SM that the abnormality has been detected by responding in a predetermined time slot following the data of the emergency polling. From the time slot, the management control panel SM determines whether an abnormality is a disaster prevention, a call, or a failure, and also determines a floor group. If the floor group is a disaster prevention, for example, the floor polling data of the disaster prevention is transmitted. Send to floor group. If the room with the disaster prevention abnormality is the third floor in the room of the floor group, the room machine J in that room sends the response to the time slot indicating that it is the third floor and sends it to the management control panel SM. .

The management control panel SM determines from the time slot that it is on the third floor, and sends room polling data to the room group on the third floor. If there is no response from the room unit J of each room in the room group, room polling data is sent to another room group. When you polled another room group,
For example, if you receive data from room 10
The control panel SM for management in the control room specifies the room No. 10, selects for collecting information of the disaster prevention content, receives a fire alarm signal from the room unit J in the room No. 10, for example, and determines that it is a fire. Display room number and fire. The above description is for the case of a fire for disaster prevention. The same applies to gas leaks, water leaks, and crime prevention. Calls and failures other than disaster prevention are also determined in the same procedure.

Next, the operation of the first embodiment will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. First, the microcomputer 1 of the communication control device TC reads the inputs of the common password setting rotary switch 8 and the dedicated password setting rotary switch 9 provided in the panel (step S1).
Next, it is determined whether or not there is a switch input of the tact switch group 6 provided in the panel (step S2). If there is a switch input, switch input processing is performed (step S3). If there is no switch input, it is determined whether or not a system error such as a microcomputer has occurred (step S4).

If a system error has occurred, error processing is performed (step S5). If no system error has occurred, the management control panel SM receiving the urgent polling request as described above. Control panel SM for alarm signal from room unit J which has been polled
Together with the call control device TC (step S
6) It is determined whether the alarm signal is a signal indicating fire, gas leak, water leak or crime prevention disaster prevention (step S7). If the signal is a signal indicating disaster prevention, the process enters disaster prevention processing (step S7). Step S8). If the alarm signal is not a signal indicating disaster prevention, it is determined whether or not the signal is a signal indicating a call (step S9). If the signal is a signal indicating a call, a call process is started (step S10). Further, when the alarm signal is neither a signal indicating disaster prevention nor a signal indicating a call, a failure process is started (step S11). When these processes are completed, the specific contents of these processes are stored in the history information memory 5 (step S12), and the process returns to step S1.

The above-mentioned disaster prevention processing means that when a fire, gas leak, water leak or crime prevention occurs in a certain room, the room number is displayed on the display of the control room control panel SM and the fire is generated by a speaker. Sounding a gas leak, water leak or crime prevention alarm, and, if necessary, notifying the management company that the room is a fire, gas leak, water leak or crime prevention. Also, call processing means that when there is a bus call or toilet call in a certain room, the room number is displayed on the display unit of the control panel for management SM, and an alarm sound of the bus call or toilet call is sounded by a speaker. Means to notify the management company that the room is making a bus or toilet call in response to the request. Further, when a failure occurs in, for example, a room unit in a certain room, the room number is displayed on the display unit of the control room control panel SM, and a warning sound of water leakage is sounded by a speaker, and if necessary, Means to notify the management company that the room is leaking.
In addition to the failure of the room unit, the failure includes a sensor disconnection, a transmission line abnormality, and the like.

The foregoing has been described up to the processing of disaster prevention, call, and failure, respectively. Next, the switch input processing and error processing will be specifically described. First, the switch input processing will be described. When entering the switch input process,
First, it is determined whether or not the error processing has been performed, but there is still an error display (S31). If there is an error display, it is determined whether or not there is a subsequent feed by the shift switch 6d of the tact switch group 6 (S32). If there is a subsequent feed, it is determined whether or not the error display is the final display. (S33). If the display is the final display, an end display is performed (S34). If it is not the final display, the next error display is performed (S35). The error display is performed on the segment display unit 7. The contents of this error display include EEPROM abnormality, RTC abnormality, RAM abnormality,
OM error, no response / false response of control panel for management, no response / false response for collective entrance unit, no response / false response for room unit, disconnection / short circuit of control panel system for control, disconnection / short circuit of collective entrance unit system, room There is a disconnection or short circuit in the machine system.

Next, when there is no error display, it is determined whether or not a time setting request for adjustment by operating the select switch 6a of the tact switch group 6 has been made (S36). If you have
The time is set. This time setting is performed in the following procedure. First, the current time displayed on the segment display section 7 is deleted (S371). Next, when the select switch 6a is operated once, "1" is displayed on the left end of the 4-digit segment display section 7. Then, one blank is placed on the right, for example, "98" of the age set previously is displayed. If it is correct, the set switch 6b is operated to set "98" of the age (S372). It should be noted that the number displayed in the age display is increased by one by operating the increment switch 6f once.
Decreasing the number by 1 is performed by operating the decrement switch 6e once.

Further, when the select switch 6a is operated for the second time, "2" is displayed at the left end of the four-digit segment display section 7, and one blank is placed to the right, for example, the previously set one is set. The month "11" is displayed, and if it is correct, the set switch 6b is operated to set the month "11" (S373). "1

e is operated once to decrease the displayed number by one.

When the select switch 6a is operated for the fourth time, "4" is displayed at the left end of the 4-digit segment display section 7, and one blank is placed on the right, for example, to set the previously set time. Is displayed, and if it is correct, the set switch 6b is operated and the time “0” is displayed.
"9" is set (S375). When "09" is not correct, the decrement switch 6e or the increment switch 6f is operated to correct the value to be correct.
When the select switch 6a is operated for the fifth time, "5" is displayed on the left end of the four-digit segment display section 7, and one blank is placed on the right, for example, "57" for the previously set value. Is displayed, and if it is correct, the set switch 6b is operated to set the minute "57" (S376). If "57" is not correct, the decrement switch 6e or the increment switch 6f
Is manipulated and corrected to be correct. Thereafter, when a predetermined time has elapsed without operating the select switch 6a, the display returns to the display of the current time (S377).

If the time has not been set, it is determined whether or not a request for the exclusive password has been made (S38). If the request for the exclusive password has been made, the exclusive password is determined. The time and time are set. This time setting is performed in the following procedure. First, the current time displayed on the segment display section 7 is deleted (S39).
1) Next, if the password set switch 6c is operated once, "1" is displayed at the left end of the four-digit segment display section 7, and one blank is set to the right, and the previously set, for example, is set. The displayed start time “05” is displayed, and if it is correct, the set switch 6b is operated to set the start time “05” (S392). The number displayed in the start time is increased by one by operating the increment switch 6f once, and the number is decreased by one by the decrement switch 6e.
Is operated once.

Further, when the password set switch 6c is operated for the second time, "2" is displayed on the left end of the four-digit segment display section 7, and then a blank is placed on the right, for example, the previously set is set. "30" for the start is displayed, and if it is correct, when the set switch 6b is operated, "30" for the start is set (S393).
If "30" is not correct and "40" is correct, the increment switch 6f is operated ten times to increase the displayed number by ten. Further, when the password set switch 6c is operated for the third time, "3" is displayed on the left end of the four-digit segment display section 7, and then one blank is placed on the right side, for example, the end which has been set before. The time "06" is displayed, and if it is correct, the set switch 6c is operated to set the end time "06" (S394). "06" is incorrect and "07"
Is correct, the increment switch 6f is operated to increase the displayed number by one.

When the password set switch 6c is operated for the fourth time, "4" is displayed at the left end of the 4-digit segment display section 7.
Is displayed, and then one blank is displayed on the right, for example, the previously set end "30" is displayed,
If it is correct, the set switch 6b is operated and "30" for the end is set (S395). "3
If "0" is not correct, the decrement switch 6e or the increment switch 6f is operated to correct the displayed number to be correct. The end time of the personal identification number is set in this manner.
When a predetermined time has elapsed without operating c, the display returns to the display of the current time (S396).

If the dedicated password has not been set, the current time is displayed, but it is determined whether or not a request for time confirmation setting has been made (S40). If so, the time confirmation setting is performed. This time confirmation setting is performed in the following procedure. First, when the shift switch 6d is operated once, "1" is displayed on the left end of the four-digit segment display section 7, and then a blank is displayed on the right side, for example, the previously set date is displayed. (S411) Further, when the shift switch 6d is operated for the second time, "2" is displayed at the left end of the four-digit segment display section 7, and one blank is placed at the right, and for example, it is set before. Is displayed (S412), and when the shift switch 6d is operated for the third time, "3" is displayed on the left end of the four-digit segment display section 7, and then a blank is placed on the right and, for example, Is displayed (S413), and when the shift switch 6d is operated for the fourth time, "4" is displayed at the left end of the 4-digit segment display section 7, and one block is displayed to the right. Hour which has been set for example to previously place the link is displayed (S414), and then returns the shift switch 6d has not been operated a predetermined time elapses, the display of the current time (S415).

Next, error processing will be described. When there is no switch input and a system error occurs to start error processing, it is first determined whether or not an error has occurred (step S51). If no error has occurred, it is checked whether there is an error (step S52). If no error has occurred, the current time is displayed (step S5).
3) After that, if a system error occurs for some reason, the next error is displayed (step S54). Also,
If a system error has occurred in step S51, it is determined whether or not an error display has already been made (step S5).
6) If there is already an error display, the contents of the system error and the error occurrence time are stored in the history information memory 5 (step S57). If there is no error display, the display of the current time is erased (step S58), an error is displayed, and the content and occurrence time are stored in the history information memory 5 (step S59).

As described above, the microcomputer 1 of the call control device TC is provided with a common password setting switch 8 provided in the panel.
And the dedicated password setting switch 9 are read, and it is further determined whether or not there is a switch input to the tact switch group 6,
If there is a switch input, perform switch input processing,
If there is no switch input, it is determined whether or not a system error such as a microcomputer has occurred. If no error has occurred with no switch input, the current time is displayed on the segment display section 7. Error 1
If any one of these occurs, an error is displayed on the segment display section 7. Each time the shift switch 6d of the tact switch group 6 is operated, the error display is performed in the order of the history. If the last error occurs, "End" is displayed. Switch 6d
Pressing returns to the original error, sees the error display, eliminates the cause of the error, eliminates the cause of the error, and when all errors have disappeared, returns to the display of the current time.
