A central monitoring board 24 is connected to the input/output interface 21 via an R5232C interface 23.

Explain the operation.

The master unit 1 polls each residential unit unit 3 in sequence. In other words, it sends a command to the unit 3 to check the situation,
Confirm after receiving the response from unit 3. This is residential unit 3
If it is confirmed that a security event has occurred in the dwelling unit 3, appropriate measures are taken such as issuing an alarm on the display 22 or the central monitoring board 24.

(Problem to be solved by the invention) However, the exchange of signals such as polling itself takes time, so even if a security event occurs in the dwelling unit 3, the base unit 1 cannot detect it. It may take a considerable time delay before it is noticed. In particular, if a security target event occurs immediately after polling is finished, it is impossible for base unit 1 to detect it during the long time it takes for polling to complete one cycle and return to all residential units 3.

This invention was made in view of the above circumstances,
The purpose of this is that when a security-related event occurs in one of the residential units, the main unit can immediately detect it without any delay and take prompt action, thereby significantly improving safety. An object of the present invention is to provide a housing management system device that does the following.

[Structure of the Invention] (Means for Solving the Problem) A base unit, a plurality of housing units connected to the base unit via respective dedicated signal lines, and occurrence of a security target event provided in these housing units. The housing unit also includes means for sending a signal to the corresponding signal line to the corresponding signal line at the same time, and means provided on the base unit to take in the signals from each of the signal lines and monitor each of the residential unit units.

(Operation) When a security target event occurs, the dwelling unit sends a signal to that effect to the corresponding signal line. The master unit monitors each residential unit by receiving signals from each signal line.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. In the drawings, the same parts as in FIG. 3 are designated by the same reference numerals, and detailed explanations will be omitted.

As shown in FIG. 1, each residential unit 3 is connected to the base unit 1 via a dedicated communication line 30.

When a security event such as a fire or intrusion by a suspicious person occurs, each dwelling unit 3 sends a notification signal to that effect via the signal line 3.
When receiving a security data request command from base device 1 after sending out the notification signal, it has functional means for sending out security data representing the content of the security target event to signal line 30.

Further, the base device 1 is provided with an analog multiplexer 40 .

The analog multiplexer 40 has a plurality of input/output terminals each assigned an address, a control terminal for address specification, and a common (SOMMON) terminal, and the input/output terminals are changed depending on the code input to the control terminal for address specification. , and connects the selected input/output terminal to the common terminal.

Each of the signal lines 30 is connected to each input/output terminal of the analog multiplexer 40 via an isolation transformer 14 and a capacitor 15, respectively. Furthermore, CPU1
An addressing control terminal of an analog multiplexer 40 is connected to the input/output interface 16 connected to the input/output interface 7 .

Further, the output of the frequency divider 12 is converted into an analog signal by the modem 13 and inputted to the common terminal of the analog multiplexer 4°. Further, the output of the common terminal of the analog multiplexer 40 is converted into a digital signal by the modem 13 and sent to the CPU 17 via the input/output interface 16.

In this way, the base unit 1 sequentially assigns addresses to each input/output terminal of the analog multiplexer 40, sequentially receives signals from each signal line 30, and monitors each dwelling unit 3. A functional means for sending a security data request command to the dwelling unit 3 when detecting that a security target event has occurred in the dwelling unit 3; It serves as a functional means to take measures such as generating alarms according to the content.

Next, the operation of the above configuration will be explained with reference to FIGS. 2 and 3.

When a security event such as fire or intrusion by a suspicious person occurs, each dwelling unit 3 sends a carrier signal (pulse 40
) is sent to the corresponding signal line 30 every 1 See.

The main unit 1 sequentially receives signals from each communication line 30 every 1 m5ec by an analog multiplexer 40, thereby scanning and monitoring each dwelling unit 3. in this case,
Even if there are 1000 residential units 3, monitoring of all of them can be completed in a short time of 1 second.

Therefore, when a notification signal is sent from the dwelling unit 3, it is immediately received by the parent Ill without a time r:i delay.

The base unit 1 that has received the notification signal retains the address specification for the signal line 30 that it has received, and sends the corresponding residential unit 3
Ensure communication status between Then, the base unit 1 sends a signal having the same frequency and width as the received notification signal to the frequency divider 12.
, convert it to an analog signal using modem 13,
It is sent to the signal line 30 as a notification confirmation signal. This notification confirmation signal is sent in the interval between receiving the notification signal and receiving the next notification signal.

The sent notification confirmation signal is taken into the dwelling unit a13.

At this time, the dwelling unit 3 stops sending out the notification signal and enters a standby state.

When the parent all no longer receives the notification signal, it sends a security data request command to the signal line 30.

The sent security request command is taken into the dwelling unit 3. At this time, the dwelling unit 3 sends security data (44 bits) with a width of 22 seconds representing the content of the security event to the signal line 30.

The sent security data is taken into base unit 1. At this time, base unit 1 confirms the content of the security data, and at the same time sends out a security data confirmation signal having the same frequency and width as the notification confirmation signal to signal line 30.

Then, the base device 1 takes appropriate measures such as issuing an alarm on the display 22 or the central monitoring board 24 according to the content of the confirmed security data.

In this way, in the conventional method, polling is performed by connecting a plurality of residential unit units 3 to the main unit 1 through dedicated communication lines 30, and monitoring each residential unit unit 3 by taking in signals from each communication line 30. 3 residential unit units in a much shorter time than the equipment.
It is possible to detect the occurrence of security-related events. Therefore, the management center can take prompt measures such as contacting the fire department or police, and safety can be significantly improved.

Furthermore, since each unit 3 is connected to the main unit 1 by a dedicated communication line 30, even if a disconnection or short circuit occurs in any of the communication lines 30, the communication failure due to this will be interrupted by some unit units. 3, so the entire system does not become unable to communicate. In other words, with conventional equipment in which each residential unit is branched and connected to a single communication line, if a disconnection or short circuit occurs in the signal line, the entire system becomes unable to communicate. In this example, such problems can be prevented.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without changing the gist.

[Effects of the Invention] As described above, according to the present invention, there is a main unit, a plurality of residential units connected to the main unit via dedicated communication lines, and security target events provided in these residential units. The present invention is equipped with a means for sending a signal to the corresponding communication line when a message occurs, and a means provided in the base unit to monitor each dwelling unit by receiving signals from each communication line. If a security-related event occurs in any of the above, the parent unit can immediately detect it without any delay and take prompt action, thereby providing an apartment complex management system that significantly improves safety. can.
