Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention enables a manager's room unit installed in a manager's room in an apartment complex to transmit and receive control signals between a manager's room unit installed in each housing unit, and a broadcast from the manager's office to each unit. The present invention relates to an apartment complex management system connected to enable the transmission of audio signals.

2. Description of the Related Art A manager room unit and a dwelling unit unit constituting this type of apartment complex management system are connected by a control signal line and also by a broadcast line. Among these, the control line is used to transmit security information from the residence unit to the manager's room unit, as well as broadcast start and end commands, etc., and the broadcast line is used to transmit audio signals when broadcasting from the manager's room to each unit. served.

[0003] When broadcasting from the manager's office to, for example, all residential units, the manager's room unit sends a broadcast start command to each unit in turn via the control signal line, or
Alternatively, send a command to start broadcasting to all residential units at once. Of these, the latter is usually adopted because the former takes time to start and end broadcasting. On the other hand, each dwelling unit that receives the broadcast start command executes so-called broadcast start processing, such as connecting a broadcast line to a speaker system or turning on an amplifier switch. In addition, when the broadcast ends, the manager's room unit sends a message via the control signal line.
Sends a command to end broadcasting to each unit at the same time. In response, the dwelling unit executes so-called broadcast termination processing, such as disconnecting the broadcast line and turning off the amplifier switch.

0004

[Problems to be Solved by the Invention] In the above-mentioned conventional apartment complex management system, a broadcast start command is sent only once from the manager's room unit to all unit units targeted for broadcasting to start broadcasting. The configuration was such that the broadcast end command was sent only once at the end of the broadcast. For this reason, it may be impossible to receive the broadcast start command or broadcast end command due to noise. For example, the broadcast will not be performed in a residential unit where the broadcast start command could not be received, and the broadcast may not be performed in a residential unit where the broadcast end command could not be received. There was a problem with noise coming from the speakers.

[0005]Also, even if we consider transmitting information on whether or not broadcasting was actually performed correctly in each dwelling unit from the dwelling unit to the manager's room machine, it is necessary to send the broadcast start command and the broadcast end command all at once. Under the current circumstances, the manager's room machine will not be able to respond. Therefore, there was also a problem in the reliability of broadcast control.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an apartment complex management system that improves noise resistance and reliability of broadcast control.

[0007]

[Means for Solving the Problems] The present invention provides a manager's room machine installed in a manager's room, which is equipped with a broadcast transmission timer whose time-up time is much shorter than the broadcast time, and which transmits the broadcast transmission timer during broadcasting. The operation is repeated, and a broadcast command is sent all at once to the residential units targeted for broadcasting at the start of broadcasting and when the broadcast transmission timer times out, respectively, and a broadcast end command is sent simultaneously to the residential units targeted for broadcasting at the end of broadcasting. On the other hand, the dwelling unit installed in each dwelling unit is equipped with a broadcast end timer whose time-up time is longer than the broadcast transmission timer, and when it receives the broadcast command for the first time, performs broadcast start processing, and also performs broadcast start processing when the broadcast command is first received. The system is configured to operate an end timer, restart the broadcast end timer each time a broadcast command is received, and perform broadcast end processing when the broadcast end timer times out and when a broadcast end command is received. .

[0008]

[Operation] In this invention, since broadcast commands are continuously sent at intervals set in the broadcast transmission timer during broadcasting, even if the housing unit fails to receive the broadcast start command once or twice, Broadcasting can be started reliably. Further, even if the residential unit fails to receive the broadcast termination command, the broadcast can be reliably terminated by expiring the broadcast termination timer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, a manager's room machine 1 installed in the manager's room of an apartment complex, an entrance machine 2 installed at the entrance, and a dwelling unit 3 installed in each dwelling unit are connected by a control signal line, and the manager's room machine 1 and the residential unit 3 are also connected via a broadcasting line. Here, the manager's room unit 1 has a control circuit 11
and the broadcast transmission timer 12 whose time-up time is set to 200 [msec].
The dwelling unit 3 includes a control circuit 31 and a broadcast end timer 32 whose time-up time is set to 2 [sec]. Each control circuit is composed of a microcomputer, and in addition to exchanging security information with each other to execute well-known security management, the control circuit 11 of the manager's room unit 1 uses a broadcast transmission timer 12 to The control circuits 31 each execute broadcast control using a broadcast end timer 32.

Operations related to broadcast control will be described below with reference to the signal format shown in FIG. 2 and the flowcharts shown in FIGS. 3 and 4.

First, when there is no broadcast, the control circuit 11 of the manager's room unit 1 and the control circuit 31 of the housing unit 3 are as shown in FIG. 2(a).
As shown in Figure 2, polling and answering back security information are repeated for each dwelling unit in sequence, information on the entire apartment complex is collected, and if necessary, measures are taken such as reporting to the outside.

Next, when broadcasting from the manager's room, as shown in FIG. 2(b), the control circuit 11 sends a broadcast command to simultaneously broadcast to the target housing units between answerback and polling. In addition to interrupting, the broadcast transmission timer 12
is started, and a broadcast command is interrupted every time the broadcast transmission timer 12 times up. Therefore, control circuit 1
1 is during broadcasting, interval 20 set in broadcast transmission timer 12
Broadcast commands are continuously transmitted at 0 [msec].

FIG. 3 shows an example of the processing procedure of this control circuit 11. That is, in step 101, it is confirmed that the reception of the security information sent from the residential unit 3 has been completed, and in step 102, it is determined whether the broadcast transmission timer 12 has timed up. and,
If the time is up, a broadcast command is transmitted in step 103, and then the broadcast transmission timer 12 is reset in step 104. On the other hand, if it is determined that the broadcast transmission timer 12 has not timed up, the next dwelling unit is polled in step 105. Although not shown in FIG. 3, a broadcast end command is transmitted when the broadcast ends.

On the other hand, when the control circuit 31 of the dwelling unit 3 receives the broadcast command for the first time, it executes the broadcast start process, and also starts the counting operation of the broadcast end timer 32.
Every time a broadcast command is received thereafter, the count value of the broadcast end timer 32 is continued to be cleared (restarted). Then, when the broadcast end command is received and when the broadcast end timer 32 times up, the broadcast end process is performed. Therefore, if the control circuit 31 receives all the broadcast commands sent from the control circuit 11, it will take 20 minutes from the broadcast start process.
The time counter of the broadcast end timer 32 is cleared every 0 [msec], and then, when a broadcast end command is received, the broadcast end process is executed, and when the broadcast end command is not received, the broadcast command is finally received. to 2 [s
ec] Broadcast end processing is executed afterwards.

FIG. 4 shows an example of the processing procedure of the control circuit 31. That is, in step 201 it is determined whether or not a broadcast command has been received, and if it is determined that it has been received, in step 202 it is determined whether or not this broadcast command has been received for the first time. Here, if it is determined that it has been received first, broadcast start processing is performed in step 203, and then,
At step 204, the broadcast end timer 32 is started. Further, even if a broadcast command is received, if it is not the first one, the counter of the broadcast end timer 32 is cleared in step 205, and a restart state is established. On the other hand, if it is determined in step 201 that no broadcast command has been received, it is determined in step 206 whether or not a broadcast end command has been received. If the broadcast end command has been received, the broadcast end process is performed in step 207, and if the broadcast end command has not been received, step 2
At step 08, it is determined whether the broadcast end timer 32 has timed up or not, and after waiting for the time up, the broadcast end processing at step 207 is executed.

Thus, according to this embodiment, two broadcast commands are sent from the manager's room unit 1 to the residential unit 3 at the same time as the start of broadcasting.
Since the broadcast command is sent continuously at an interval of 0.00 [msec], even if the dwelling unit 3 does not receive this broadcast command once or twice, it can start broadcasting. Also,
Even if this broadcast command is not received once or twice during broadcasting, if it is received once within 2 [sec], which is the time-up time of the broadcast end timer 32, broadcasting can be continued.

Furthermore, even if the broadcast end command is not received, the broadcast end process is executed in about 2 seconds, so there is no problem such as continuous noise coming from the speaker.

In the above embodiment, the broadcast transmission timer 12 whose time-up time is set to 200 [msec] and the broadcast end timer 32 whose time-up time is set to 2 [sec] are used. Use a timer whose time-up time is much shorter than the broadcast time,
If a timer with a longer time-up time than the broadcast transmission timer 12 is used as the broadcast end timer 32, the same operation as described above can be achieved.

[0019]

Effects of the Invention As is clear from the above explanation, according to the present invention, even if the broadcast command at the time of broadcast start cannot be received, the broadcast can be started by the subsequent broadcast command, and the broadcast can be started by the broadcast end command. Even if the broadcast fails to be received, the broadcast can be ended by the broadcast end timer, thereby improving the noise resistance performance and the reliability of broadcast control.
