[0010]
Reference numeral 11 denotes a terminal device installed in each dwelling unit of the apartment house, for example, a housing information panel having an intercom function and security functions such as crime prevention and calling. When predetermined data transmitted from the control device 1 is received, A microcomputer 12 having a function of transmitting data indicating its presence at a predetermined timing; a receiving circuit 13 that converts a pulse received via the control path 21 into a digital signal and outputs the digital signal; And a transmission circuit 14 that converts the digital signal into a pulse and transmits the pulse to the control device 1 via the control path 21. This terminal device 11 has an interphone handset (not shown) and is connected to a door phone, a security sensor provided in each room, a water leak sensor, a call button provided in a bath or a toilet, etc. The terminal device in the entrance and the management room is connected via the control device 1. In FIG. 1, illustration of a communication path between interphones, a communication device circuit of the control device 1 and the terminal device 11 of each dwelling unit is omitted for convenience of explanation.
[0011]
Here, data provided with return timings for a plurality of terminal devices will be described. FIG. 2 is a format diagram showing polling data for confirming the presence / absence of a terminal device.
This data consists of blocks AS1 and AS2 for writing addresses, a block CM for writing commands, blocks DA1 and 2 for writing data, and blocks SM1 and SM2 for determining the presence or absence of errors in the data. A time slot (return timing) is set so that the device can notify its presence. For the terminal device 11 of the dwelling unit, time slots for 8 dwelling units are set as shown in FIG.
[0012]
Next, the operation according to the present embodiment will be described with reference to FIGS. 3 and 4 are flowcharts showing the operation of the control device for confirming the presence / absence of the terminal device. Note that the operation of the present embodiment is performed only for the terminal device of each dwelling unit, and the operation of the control device for each terminal device of the management machine and the front door is basically the same as the terminal device of each dwelling unit, and is therefore omitted.
[0013]
The control device 1 performs polling for confirming the presence / absence of the terminal device 11 when a predetermined time elapses after monitoring the terminal device 11. First, measurement of the transmittable time is started and it is determined by sensing the control path 21 whether or not transmission is possible within that time, that is, whether or not the control path 21 is being used by another terminal device or the like (S1). ~ S3). When transmission is not possible even after the transmittable time elapses, that is, when the control path 21 is used, the measurement time is cleared and the time measurement is started again (S4, S1), but transmission is possible within the transmittable time. When sensing is detected through sensing, polling is performed by transmitting data in which time slots are set to the eight dwelling units (Rooms 101 to 108) on the first floor (S5). When this data is transmitted, the measurement of the standby time is started and the system waits until the time is up (S6, S7).
[0014]
At this time, when receiving the data, each of the terminal devices 11 in the rooms 101 to 108 transmits data notifying the presence of itself to the control device 11 in the set time slot. On the other hand, when the control device 1 confirms that the standby time is up, the control device 1 clears the measurement time and determines whether or not data has been received from each terminal device 11 (S8, S9). When there is no received data, it is determined whether the dwelling group (8 dwelling units) that performs polling has ended (S10), but when data reception is detected, it is sequentially determined whether the data is normal. (S12).
[0015]
When the first data, that is, the data of the terminal device 11 in the room 101 is normal, the presence of the terminal device 11 is recorded in the memory (S13), and the presence / absence search of the terminal devices 11 for 8 units is performed. It is determined whether or not the processing has been completed (S23). This not completed case, data terminal equipment 11 of the next 102, Room it is determined whether the normal (S12), the normal case, record the presence of the terminal device 11 in the same manner as described above in the memory you (S13).
[0016]
If it is determined in S12 that the data in the terminal device 11 in the room 103 is abnormal, first, the presence or absence of data is determined (S14). When there is no data, it is determined whether or not the terminal device 11 is recorded in the memory as the previous presence (S15). This previous presence is the presence of the terminal device 11 when the previous polling is performed. If the terminal device 11 has not existed from the previous time, the absence of the terminal device 11 is recorded in the memory (S18). If it has existed the previous time, the terminal device 11 does not exist. Is recorded in the memory (S16). Then, the terminal device 11 in the management room is caused to display an abnormality and sound an alarm sound in the terminal device 11 in the room 103 (S17).
[0017]
On the other hand, when it is determined that there is data in S14, it is determined that the data could not be read, and it is determined whether or not this state has been repeated three times in succession (S19). When the state is less than 3 times, the terminal device 11 in the room 103 is recorded as being present in the memory (S22). If the data cannot be read three times in succession, it is recognized that the data is duplicated, and the data abnormality display and alarm sound of the terminal device 11 in the room 103 are displayed. Let the device perform (S20, S21).
[0018]
Thus, the presence / absence of the terminal device 11 is searched based on the received data until the eight dwelling units are completed, and when it is completed, it is determined whether the dwelling unit group has ended in S10 as described above. If the dwelling unit group has not ended, the next dwelling unit group (rooms 109 to 116) is selected (S11), and data is again transmitted to the group to perform presence / absence polling. When the dwelling unit group has ended, the processing of the presence / absence of this terminal device 11 is ended and normal monitoring starts. Then, when the predetermined time has elapsed, the process of the presence / absence of the terminal device 11 is entered again.
[0019]
As described above, in the present embodiment, at predetermined time intervals, data provided with time slots for eight dwelling units are transmitted to each terminal device 11 to monitor the state of the terminal device 11 and are managed in the event of an abnormality. Since the information is displayed on the terminal device in the room, there is no need to manually check the terminal device, and the function of the intercom system can be maintained by quickly dealing with the abnormal terminal device.
[0020]
In the above embodiment, the alarm sound shown in S21 of FIG. 4 may be distinguished from the alarm sound in S17 of FIG. Moreover, although the said embodiment demonstrated the intercom for apartment houses, it cannot be overemphasized that it can apply to the intercom apparatus of a detached house which does not have a security function.
[0021]
【The invention's effect】
As described above, according to the present invention , one of a plurality of dwelling unit groups is sequentially selected for each predetermined period, and for each selected dwelling unit intercom terminal device, the presence of each unit Data for polling that confirms the existence / non-existence of a dwelling unit intercom terminal device for which a return timing for notifying the data is set is sent to the control path, and each dwelling unit intercom terminal device of the selected dwelling unit group Data is received at each return timing, and the received data is taken in sequence to determine whether it is normal or abnormal. If it is determined to be normal, the data transmission source terminal unit for intercom is recorded as present. If it is determined that there is an abnormality, there is data to notify its existence during the return timing of the terminal device for dwelling unit intercom that is the data transmission source. If it is determined that there is no data during the return timing, the dwelling intercom terminal device is identified from the return timing, and it is determined whether the dwelling intercom terminal device has been recorded as the previous presence. When the dwelling unit intercom terminal device was present last time, it is recorded as non-existing, and an abnormality indicating that the dwelling unit intercom terminal device is not present is displayed on the display means. If it is determined that there is data, it is determined that the data cannot be read, and it is determined whether the number of times of the state continues for a predetermined number of times.
