Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a security system for so-called complex buildings or tenant buildings where a plurality of offices with different working hours coexist.

The conventional general security system for complex buildings or tenant buildings is that each office in the building is designated as a separate security area, and the final person leaving each office uses a key or other method to secure the security area of his or her own office (hereinafter referred to as the self-security area). ) is put in a security state, and if some abnormal situation occurs and a sensor installed in the security area detects it, for example, an alarm transmitter will alert a remote security monitoring center ( It was intended to send an alarm to the security center (hereinafter referred to as the security center). However, with this type of security system, entrances, hallways,
There was a problem with the security of common areas such as side entrances, elevators, and halls (hereinafter referred to as common areas). That is, in order to make the common area a security area like each business office, for example, the last person leaving the entire building needs to put the security area of the common area (hereinafter referred to as the common security area) into a security state, so conventional In this security system, it is necessary to perform the operation twice in order to put the self-security area and the common security area into a security state, respectively, and there is no means to identify the last person leaving the entire building and to communicate the result to the person leaving the building. This method had the drawback that it was prone to operational malfunctions due to the use of multiple methods, and could not be considered an effective method. Therefore, in many cases, only business offices were designated as security zones, and common areas were left unguarded, making it impossible to take effective security measures.

Next, we will discuss another recently announced conventional example (Special Public Interest Publication No.
According to No. 40550), for example, the common security area can be automatically placed in the security state using the detection means that detects that all of the self-security areas have been placed in the security state, so that the building The self-secured area corresponding to the last exiting person is immediately put into a guarded state, and after a predetermined period of time, the entire building is put into a guarded state. However, with this security system, the common security area in the common area of the building cannot be kept under security until the last person leaves the building, and the drawback is that it is not possible to provide a sufficient security system for the building. It was hot.

The present invention has been made in order to solve the above-mentioned drawbacks of the conventional ones, and is a security system that uses an abnormal situation detection means for a complex building where multiple offices with different working hours coexist. The object of the present invention is to provide a new security system for complex buildings, etc., which is characterized by individually putting buildings into a security state and automatically putting a common security area into a security state at a preset time.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a security system according to an embodiment of the present invention. In the figure, 1 is a complex building where multiple offices with different working hours coexist, and 2 is the main entrance of the building 1 closed. Side entrance to be used later, 3a~
3c is each office and its self-security area; 4 is the building common area including toilets, passages, entrances, etc. and its common security area; 5a to 5d are detectors for detecting fire, intrusion, equipment abnormality, etc.; They are arranged in the self-security areas 3a to 3c and the common security area 4. 6a to 6c are office security switches (hereinafter referred to as security switches) provided near the self-security areas 3a to 3c of each of the above business establishments, and are security activation switches (described later) that put the self-security areas 3a to 3c into a security state. and a security release switch, which will be described later, for releasing the security state of the common security area 4.
7 is a common security area timed security switch (hereinafter referred to as a timed security switch) that automatically puts the common security area 4 into a security state at a preset time; 8 is a common security area timed security switch that centralizes the security information of each of the security areas 3a to 3c, and 4; It is a centralized processing control device that has the function of processing and transmitting necessary information to a security center (not shown) connected to it via a communication line.

In the above configuration, for example, the offices 3a, 3
The last person to leave the offices 3a and 3b among the offices 3a and 3c sets the self-security areas 3a and 3b to the security state using the security switches 6a and 6b, respectively, and enters the side entrance 2.
Exit through. After that, timed security switch 7
At a preset time, the timed security switch 7 is activated and the common security area 4 is automatically placed in a security state. At this point, if an abnormal situation such as an intrusion or a fire occurs in a self-secured area other than the business office 3c where the remaining person is present, the central processing control device 8 sends an alarm to a security center (not shown). Next, when the last person to leave the office 3c puts the self-security area 3c into a guarded state by the security switch 6c, or if the person leaving the office 3c is not the last person to leave the office 3c, the security of the common security area is released. When operating a switch (described later), a timer device (described later) that releases the common security area that is already in a guarded state for a set time that takes into consideration the time it takes for the exiting person to walk to the side entrance 2. is started. Therefore, if the exiting person exits through the side door 2 while the timer is operating, no alarm will be sent to the security center.
However, after the predetermined time has elapsed, the device stops, and the common security area 4 returns to the security state again, and all security areas of the building become security.

Next, a security system according to an embodiment of the present invention will be described in more detail with reference to FIG.

FIG. 2 is a detailed circuit diagram of the security system shown in FIG. 1, where the same reference numerals as in FIG. 1 indicate the same or equivalent parts, and 10a to 10g are AND gates,
9 has a function of blocking the input signal from the time guard switch 7 for a preset time activated by the input from the AND gates 10d, 10e, and 10f, and stopping the output to the AND gate 10g. Multi-input time limit switch, 11a-11
d is an OR gate, and the output of the OR gate 11d is connected to the security center via the central processing control device 8. 12a to 12c are self-security area security activation switches (hereinafter referred to as security activation switches) that individually put the self-security areas 3a to 3c into a security state, and 13a to 13c each independently deactivate security for the common security area 4. This is a common security area release switch (hereinafter referred to as a common security release switch), and the two switches form a pair and are built into the security switches 6a to 6c. 1
Reference numerals 4a to 14c denote monostable multivibrators, which are configured to output constant pulses according to the outputs of the security input switches 12a to 12c.

The operation will be explained based on the above configuration.

Now, when the last person leaving the self-secured areas 3a, 3b operates the security input switches 12a, 12b that constitute the security switches 6a, 6b, the inputs of the AND gates 10a, 10b turn ON, and the sensor 5
When a and 5b detect an abnormal situation, the AND gates 10a and 10b transmit the alarm signal to the OR gate 11.
Output to d. At the same time, AND gates 11a, 1
1b is also monostable multivibrator 14a, 14b
However, at this time, the timed security switch 7 has not reached the set time to put the common security area 4 into the security state, so there is no output.
There is also no output from AND gates 10d, 10e, and 10f. Thereafter, at the set time, a signal is output from the timed security switch 7, and this output signal is passed through the multi-input timed switch 9 to the AND gate 1.
Input to 0g. Therefore, when the sensor 5d installed in the common security area 4 detects an abnormal situation, an alarm signal is output from the AND gate 10g.

Next, when a person who is not the last to leave the office 3c operates the common security release switch 13c, the output signal is sent via the OR gate 11c.
It is input to AND gate 10f. At this time, the applicable
Since the AND gate 10f has already received the input signal from the timed security switch 7 at one of its input terminals, it takes the AND of the above-mentioned re-inputs and outputs a signal, and this output signal causes the multi-input timed switch to be activated. 9 is activated, AND from timed security switch 7
The output to the gate 10g is cut off for the above set time. Therefore, even if the sensor 5d in the common security area 4 is activated during this set time, the AND gate 10
g alarm signal is not output. After the set time has elapsed, the multi-input time limit switch 9 is restored, and the output of the time limit security switch 7 is output to the AND gate 10.
g, and the sensor 5d returns to the security state.

Next, when the last person leaving the office 3c operates the security switch 12c, the AND gate 10
A signal is input to c, and if the sensor 5c detects an abnormal situation, an alarm signal will be output from the AND gate 10c. On the other hand, the output of the security input switch 12c is the monostable multivibrator 14c→OR gate 11c→AND gate 10.
The AND gate 10f sends a signal to the multi-input time switch 9 by this pulse input.
Output to. As a result, the multi-input time limit switch 9
cuts off the output of the timed security switch 7 for a preset time and releases the security state of the common security area 4, so that the last exiting person can exit through the side entrance 2 during this time. After the set time has elapsed, the output of the timed security switch 7 is turned on again.
This is input to the AND gate 10g, and the common security area 4 returns to the security state.

As described above, according to an embodiment of the present invention, by providing a security switch for each business establishment that includes a self-security area security activation switch and a common security area security release switch for each self-security area of each business establishment, With a single operation of this security switch, the self-security area of each business office is put into a security state individually, and after the specified time, there is almost no leakage except for the short time it takes for those leaving the common security area to leave. This provides the great advantage of being able to maintain a guarded state without any problems.

In addition, in the above example, a security switch for each business establishment, which has a built-in self-security area security activation switch and a common security area security release switch, is installed near each business establishment, but each establishment is coded separately. A magnetic card with a magnetically recorded verification code is provided in advance to each business establishment, and a magnetic card reading device that reads the verification code of the magnetic card is installed near each business establishment or in place of the above-mentioned security switch for each business establishment. It is clear that even if it is installed near the building management room if necessary, the same effect as the above embodiment can be achieved.

It should be noted that the present invention is not limited to the configuration of the above-described embodiments, but may of course be subject to various design changes as long as they do not deviate from the technical idea set forth in the claims.

As explained above, according to the present invention, even in facilities where offices with different working hours coexist, such as complex buildings, where it has been difficult to provide security,
By introducing a security method in which the self-secured areas of each business office are individually secured, and the common security area of the common area is also put under security after a predetermined time,
The common security area in the common area of the building can be reliably put into a security state, and moreover, the common security area, which has become unmanned after the above-mentioned predetermined time, can be maintained for the most part, except for a short period when the remaining exiters leave. This has the great effect of keeping you in a state of security without any leaks.
