Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a security system that manages and controls the security of a defined security area in cooperation with a remote central control center, and particularly relates to a security system that controls the security of a defined security area in cooperation with a remote central control center. canceled (resolved)
Regarding the security system that has been improved to zero.

Conventional technology Anomaly detection means for detecting anomalies such as intruder detection, fire detection, gas leak detection, etc. in a restricted area and sending out a detection signal, and in response to these anomaly detection means, discrimination by abnormality type, abnormality display, A security system consisting of an alarm device that controls alarm processing such as sending out abnormal signals according to the type of security mode, and a central control center that is remotely linked to this alarm device to provide complete security for a guarded area. is already in general use. In such a security system, the security target,
In other words, security zones range from buildings such as factories and offices to general residential buildings and special venues, but especially in the case of general residential buildings, the entire area must be guarded even if there are people home at night. It is used to detect any abnormalities, display abnormalities, and notify abnormalities by setting the mode. Therefore, if there is an intruder from outside, an intruder abnormality will be detected immediately, but on the other hand, even if a person at home opens a window or door while maintaining alert mode, it will be detected as an intruder abnormality. Anomaly detection is performed. In order to eliminate such inconveniences, operating means such as buttons and switches that temporarily stop the signal generation function are installed near each abnormality detector for detecting an intruder abnormality or in the transmitter part of the abnormality detector. However, as mentioned above, when a person at home opens a window, he or she operates a button or switch to cancel the signal generation function, and then when the person closes the window again after opening the window, It is necessary to operate the button or switch again to regenerate the transmission function. Therefore, in the method described above, which eliminates the hassle of requiring two operations and the signal generation function on the abnormality detector side,
The alarm device, which performs security processing control by receiving abnormal signals, cannot be involved in the actions of people who are home at all, such as opening a window, so if a person forgets to close a window or forget to operate the transmission function, security will be compromised. Problems we are trying to solve that may occur: In order to prevent security leaks such as those mentioned above, when the alarm mode is set, the alarm system is also involved in the movements of people at home, but unnecessary abnormalities are detected. It is necessary to construct a security system equipped with an appropriate canceling means that can cancel signal transmission, etc.

Therefore, it is an object of the present invention to provide a security system with an improved configuration capable of satisfying such needs.

Solution Means and Effects According to the present invention, there is an anomaly detecting means for detecting an anomaly to detect an intruder in a warning area, and an alarm including anomaly type discrimination, anomaly display, and anomaly signal sending in response to the anomaly detecting means. In a security system comprising an alarm device that controls processing according to the type of security mode, and a central control center that is remotely linked to the alarm device, the present invention further comprises: a cancellation activation means for activating cancellation of an intruder detection signal; mode discriminating means for discriminating the security mode type of the warning area in the alarm device; received signal discriminating means for receiving the activation signal from the cancel activation means and the abnormal signal from the abnormality detection means and determining the signal type; storage and notification means for holding or transmitting the intrusion abnormality signal determined by the received signal discriminating means for a certain period of time, and canceling and activating the intrusion abnormality signal in response to reception of the cancel activation signal of the cancel activation means; It is determined whether or not an intrusion abnormality signal is received from the received signal determining means during a certain period of time before or after the signal is generated, and when the intrusion abnormality signal is received, the intrusion abnormality stored in the storage and notification means is determined. A security system is provided, which is characterized in that it is equipped with cancellation activation means that generates a clear signal for clearing the signal, and therefore cancels an abnormal signal indicating an intruder abnormality within the alarm device as necessary, for example. This prevents the abnormality signal from being sent to the central control center, and allows the person at home to confirm only the location where the intruder abnormality has occurred. Furthermore, it is possible to designate a specific intrusion anomaly detection means among a large number of intrusion anomaly detection means provided within the warning area, and cancel the intrusion anomaly detection signal a specified number of times. Hereinafter, the present invention will be explained in more detail based on the accompanying drawings.

FIG. 1 is a detailed block diagram showing the configuration of an embodiment of the security system according to the present invention, and FIG. 2 is a schematic configuration diagram of the security system.

Now, FIG. 2 shows a schematic configuration of an embodiment in which the present invention is applied to a one-way security system using wireless. An intrusion detector 1 detects intrusion anomalies in the event of damage or destruction; an intrusion transmitter 2 converts the intrusion anomaly detection signal into a wireless signal and transmits the signal; detects intrusion anomalies in windows that are permanently closed or in areas that are not normally opened or closed; A 24-hour sensor 3 that detects an intrusion abnormality for 24 hours regardless of the security mode, a 24-hour transmitter 4 that converts the detection signal of the 24-hour sensor 3 into a wireless signal and transmits it, and an intrusion. a cancellation activation device 5 that wirelessly sends out a cancellation activation signal for canceling an abnormal signal; the above-mentioned intrusion detector 1 and 24 hour sensor 3 installed within the warning area; a cancellation activation device 5;
Detection signals transmitted by abnormality detection devices, etc. that detect fire abnormalities, gas leak abnormalities, and other abnormalities (not shown);
An alarm device 6 that performs warning processing in response to a recovery signal, a cancel activation signal, etc., and a transmitter 7 coupled to this alarm bag W6.
, an alarm lamp drive circuit 8 using an electric light line conveyance path, an alarm lamp 9, a buzzer circuit 10, and a transmitter 7 at the alarm position 6.
Centralized control center 11 connected remotely via
is equipped. Note that the central control center 11 is also connected to alarm devices installed in other guarded areas to constitute other security systems.

In the security system having the above-described configuration, an example of the detailed configuration of the cancellation activation bag M5 provided by the improvement according to the present invention is shown in FIG. The cancellation activation device shown in FIG. 3 is a portable embodiment that is battery-powered and can be carried around within the restricted area.The cancellation activation device shown in FIG. Code setting section 14, create a unit code that identifies it as a cancel activation device (unit code creation circuit 15 formed of read logic, non-locking cancel switch 16, one-shot multi-bye break 17, LED drive circuit) 8
, an LED 19, a radio signal transmitter 20, and an antenna 21. When the cancel switch 16 is pressed by an operator (for example, a person living at home in the restricted area), the cancel signal forming unit 12 generates a designated house code and unit code that are set for the relevant restricted area by the house code setting unit 14. This is a circuit portion that forms a cancel activation signal created by adding the unit code of the cancel activation device created by the creation circuit 15 to cancel ON, and is formed by an LSI element. Further, when the cancel switch 16 is pressed, the one-shot multi-bye break 17 sends a cancel ON signal to the cancel signal forming unit 12, and also for a certain period of time (for example, 1 minute) to confirm that the cancel switch 16 has been pressed. LED drive circuit 1 for several seconds)
The LED 19 is turned on throughout the day. Dead battery circuit 13
cooperates with a check circuit built into the LSI of the cancel signal forming unit 12 to check whether the battery has a normal potential at a specific cycle, and outputs a high signal if the battery is normal; If the voltage is below the specified voltage, a low signal is sent to the cancel signal forming section 12. Therefore, when the cancel signal forming section 12 receives a low signal indicating battery exhaustion, it adds the house code and the Uniso I-code to the low signal to form a low battery signal, and immediately transmits the signal to the wireless signal transmitter 20 and the antenna 21. A warning bag W6 shown in FIG. 2 notifies that the battery is exhausted.

As mentioned above, both the cancel activation signal and the dead battery signal have the signal form shown in FIG. 4, in which a house code and a unit code are added. 01 code, the cancellation activation device 5 of the predetermined caution area
The alarm device can receive and identify that (FIG. 2) is canceled or the battery is dead. In addition, when the cancel signal forming unit 12 forms and sends a cancel activation signal or a dead battery signal in advance, it is not a single signal, but is sent several times in succession, and the alarm device 6 receives the signal due to interference or other causes. It is preferable to take measures to prevent failure.

The signal form similar to the signal form sent out by the cancellation activation device 5, which is composed of the house code, unit code, and cancel on code or battery dead code described above based on FIG. sensor 3
It is also used as the sending signal for the intrusion abnormality detector 1.24H sensor 3 is a battery-powered type. If so, it is naturally used to form a dead battery signal.

FIG. 5 is a block diagram showing another embodiment of the cancel activation device 5 (FIG. 2). When compared with the embodiment shown in FIG. 3, this embodiment differs in that it additionally includes a canceled uni-node setting section 22 connected to the cancellation signal forming section 12. This canceled unit setting section 22 is formed by a di-nopusui-nochi or a numeric keypad,
It is possible to specify in advance the intrusion anomaly detector 1 (Fig. 2) whose anomaly detection signal is to be canceled within the warning area.For example, an intrusion anomaly detector installed in a bedroom window can be used. It is also possible to specify in advance so that only the abnormality detection generated from the device 1 and the intrusion abnormality detector 1 installed in the hinged door of the living room can be canceled, and other intrusion abnormality detectors 1 cannot be canceled. In other words, it can be canceled on the alarm device 6 (Figure 2) side by incorporating a code indicating the intrusion abnormality detector 1 that can be canceled in advance into the cancellation activation signal, or by setting it each time using the depth inch or numeric keypad described above. It is possible to identify which intrusion anomaly detector l the intrusion anomaly detection signal comes from. In addition, the fifth
The format of the cancellation signal sent from the cancellation activation device 5 of this embodiment shown in the figure is a signal format in which the display code of the unit to be canceled is incorporated after the unit code, as shown in FIG. In addition, instead of setting the target to be canceled as a specific intrusion detector as described above, if a block code is provided in advance for a specific block (partial area) of the guarded area so that it can be specified, the unit to be canceled can be set as described above. It is also possible to form the section 22 as a canceled block setting section so that the alarm device side can identify cancelable blocks. Furthermore, the above-mentioned canceled unit setting section 22 can be used to set the number of intrusion abnormality detection signals that can be canceled as, for example, two abnormal signals generated before a certain period of time from the push operation of the cancel activation device 5 or after a certain period of time. It is also possible to use it as a means to set the number of signals as a code for the two abnormal signals that occur. In such a case, if the alarm device receives three abnormal detections before or after a certain period of time, 3 When receiving the first item, a warning process can be performed to prevent cancellation.

In the above description, two embodiments have been described in which the cancellation activation device 5 is formed into a portable type driven by batteries, but of course it can also be configured into a fixed type in a restricted area using a commercial power source instead of being driven by batteries. It goes without saying that it is also possible to configure the system, and for example, it is possible to incorporate it into an alarm device 6, which will be described later.

Next, an alarm device 6 equipped with a canceling function according to the present invention
The detailed configuration and operation of the alarm bag N6 will be explained below with reference to FIG. It is described in Utility Application No. 1983. Therefore, the first
It should be understood that the detailed configuration of the alarm device shown in the figures shows the main parts and related components of the present invention.

In FIG. 1, a receiver 23 is provided to receive an abnormality detection signal, a recovery signal, a dead battery signal, and a cancel activation signal sent from the above-mentioned intrusion abnormality detector 1, 24H sensor 3, and cancel activation device 5. It is also equipped to receive signals such as fire abnormalities, gas leak abnormalities, emergency abnormalities, etc. The mode controller 24 is a means for setting the security area to various security modes, for example, the security release state, which is mainly set when there are people at home during the day.
There are three modes: "at home" mode, "night mode" which is an alert state that is mainly set when someone is home at night, and "going out mode" which is an alert state that is mainly set when no one is home. Mainly set.

The circuit system of the receiver 23 includes a house code storage circuit 2.
5, a unit code discrimination circuit 28 connected to the unit code storage circuit 27, a signal code discrimination circuit 29, a first timer 30, a buffer circuit 31, a first LED drive circuit 32, a sending circuit 33, and an audio output circuit. 34, a second LED drive circuit 35, a cancel drive circuit 36, etc. are connected, and a mode discrimination circuit 37, a field mode storage circuit 38 are connected to the circuit series of the mode controller 24.
, a cancel signal normality determination circuit 39 is connected.

The mode discrimination circuit 37 includes a first OR gate 40, a first AND gate 41, a second AND gate 42, and a third AND gate 43, and the current mode storage circuit 38 includes a first flip-flop 44, a second flip-flop 45, and a third AND gate 43. 3
A flip-flop 46 and a second OR gate 47 are provided.

Further, the cancel signal normality determination circuit 39 is provided with a third OR gate 48 and a fourth AND gate 49. Further, the above cancel drive circuit 36 includes a fifth AND gate 50. A sixth AND gate 51, a second timer 52, a rising differentiation circuit 53, a falling differentiation circuit 54, a fourth flip-flop 55, a seventh AND gate 56, a clear circuit 57, a counter circuit 58, an inverter 59, etc. are provided.

In the above configuration, the signal received by the receiver 23 is
As mentioned above, the signal has the form shown in FIGS. 4 and 6, and the corresponding signal discrimination circuit 26 discriminates the house code by comparing it with the house code read from the house code storage circuit 25. It is then determined whether the signal is from the warning area or not. The received signal that has passed through this pertinent discrimination circuit 26 is compared with the unit code called out from the unit code storage circuit 27 by the unit code discrimination circuit 28, thereby determining whether the plurality of intrusion abnormality detectors 1, cancel activation devices 5, 24, . It is determined which unit in the H sensor 3 (FIG. 2) or the like the signal comes from. The received signal that has passed through the unit code discrimination circuit 28 is subjected to a signal code discrimination circuit 29 which discriminates whether the signal code is a dead battery code, an abnormality detection code, a recovery code, a cancel-on code, or the like.

In this case, it is determined that the abnormal signal is generated from an abnormality detector other than the intrusion detector 1, and it is determined that the batteries of all the abnormality detectors including the intrusion abnormality detector and the cancel activation device 5 are exhausted. In this case, the output circuit 3 passes through circuit a.
The determination result is sent to the control center 11 shown in FIG. 2 from the sending circuit 33. Also,
When it is determined that the signal is an abnormality detection signal of the intrusion abnormality detector 1 through the signal code determination circuit 29, and when it is determined that it is a recovery signal, the signals are transmitted to the first LED drive circuit 32 through the circuit. is sent, and the position of the intrusion anomaly detector that detected the anomaly or the intrusion anomaly detector that has been restored is displayed. On the other hand, the abnormality detection signal of the intrusion abnormality detector 1 activates the first timer 30 and is sent to the buffer circuit 31, and the signal determined by the first timer 30 is sent to the buffer circuit 31, unless the alert area is set to the at-home mode in which the alert is released. It is stored for a certain period of time T1. If the canceling action does not occur during the storage period of the certain time T1, the circuit C
The signal is sent to the sending circuit 33, the audio output circuit 34, and the second LED drive circuit 35, and the intrusion abnormality is notified to the control center 11 (Fig. 2) through these circuit means, and the abnormality detection is displayed by audio output. , and an abnormality is displayed by turning on or turning off L'ED.

Now, to explain how to set the security mode using the mode controller 24, the mode controller 24 can be used to switch between home mode (alert release) and night mode (alert state with someone at home).
, out-of-home mode (absence alert state) is operated, the mode discrimination circuit 37 adds the code confirmation condition of the operator, and the first AND gate 41 generates an output in the at-home mode. The second AND gate 42 receives an output during the night mode, and the 37th AND gate 43 receives an output during the outing mode. These outputs are the first . Second. Third flip-flop 44, 45
, 46, respectively, to store the current mode and reset the corresponding flip-flops storing the previous mode if the previous mode was another mode. In addition, when switching between the above modes, switching from night mode or out-of-home mode to home mode, and switching from home mode to night mode or out-of-home mode is permitted, but switching directly from night mode to out-of-home mode is permitted. The mode discriminating circuit 37 has the current mode storage circuit 38, the first j
Second. A mode signal is fed back from the output terminals Q1p Qz and Qs of the third flip-flops 44, 45, and 46. The first in the mode discrimination circuit 37
The OR gate 40 is provided to determine the logical sum condition between the night mode and the outing mode described above. Further, a second OR gate 47 included in the current mode storage circuit 38 is connected to the second flip-flop 45 and the third flip-flop 46, so that a signal is generated at the second OR gate 47 in the night mode or out-of-home mode.

That is, the output of the second OR gate 47 indicates a warning state common to both modes, and the output of the second OR gate 47 is sent to the signal code discriminating circuit 29, which determines the current mode of the warning area when determining the signal code. We are giving conditions such as being on alert. Of course, it goes without saying that if the output of the second OR gate 47 is zero, the current mode of the guarded area is in the state of being cleared.

On the other hand, each output of the first flip-flop 44 and the second flip-flop 45 is sent to the third OR gate 48 of the cancel signal normality determination circuit 39. That is, the third OR gate 48 produces an output in the attended state, which is a common logical condition for the at-home mode and the night mode. The output of the third OR gate 48 is sent to one input terminal of the fourth AND gate 49, and the cancel-on signal from the signal discrimination circuit 29 is input to the other input terminal of the fourth AND gate 49. It has become. That is, the output of the fourth AND gate 49 is generated when the cancel activation bag w5 is activated in a manned state.

Next, the canceling effect, which is a feature of the present invention, will be explained.

The cancellation action is performed to eliminate the intrusion abnormality signal by operating the cancellation activation device 5 to generate a cancellation activation signal as necessary. Therefore, the cancellation activation signal is a signal that is generated only when the caution area is manned. That is, for example, when a person at home wants to temporarily open a window when the guarded area is set to night mode, the system operates to cancel the abnormal intrusion signal caused by opening the window. Therefore, when the cancellation activation device 5 for the caution area is activated in the manned state, an output is generated to the fourth AND gate 49 of the above-mentioned cancellation normality determination circuit 39, and the cancellation action is started. That is, the fourth
The output of the AND gate 49 is the fifth. 6th and game) 50
．． 51, and the other input terminal of the fifth AND gate 50 is connected to the buffer circuit 3 described above.
I is connected to the buffer circuit 31 so that the presence or absence of an intrusion abnormality detection signal stored in the buffer circuit 31 can be input.

The other input terminal of the 6th AND game) 51 is the inverter 59
Since it is connected to the buffer circuit 31 via the buffer circuit 31, when the detection signal of an intrusion abnormality is stored in the buffer circuit 31, the signal is applied when the output is not stored as 0=1. Here, the buffer circuit 31 stores the intrusion abnormality detection signal only for a certain period of time T1 determined by the first timer 30 as described above. Therefore, the fifth AND gate sends an output to the clear circuit 57 and drives the clear circuit 57 when an intrusion abnormality is detected during the above-mentioned fixed time T1 from the time when the cancel activation signal is received. By sending a clear signal from the buffer circuit 31 to the buffer circuit 31, the intrusion abnormality detection signal stored in the buffer circuit 31 is erased. In other words, the buffer circuit 31
This prevents the transmission of an intrusion abnormal signal from the circuit C to the circuit C.

On the other hand, when the intrusion abnormality signal is not stored in the buffer circuit 31 for a certain period of time T1 before the cancellation start signal is received, an output is generated at the sixth AND gate 51. The output of the sixth AND gate 51 is the second timer 52
is activated for a certain period of time T2, and the first timer 3
Stop 0. When the second timer 52 is activated, the output of the rising differentiation circuit 53 is input to the set terminal S of the fourth flip-flop 55. Further, when the predetermined time T2 of the second timer 52 has elapsed, the output of the differential circuit 54 rises and is inputted to the reset terminal R of the fourth flip-flop 55. That is, the fourth flip-flop 55 sends an output to one input terminal of the seventh AND gate 56 for a certain period of time T2 determined by the second timer 52 after receiving the cancel activation signal. This 77th gate 5
Since the circuit connection is formed such that the intrusion abnormality detection signal is inputted to the other input terminal of the signal code discrimination circuit 29, when the intrusion abnormality detection signal is generated during the above-mentioned fixed time T2, the intrusion abnormality detection signal is detected. When the detection signal is stored in the buffer circuit 31, the seventh AND gate 56 and the count circuit 58
, the stored intrusion abnormality detection signal is erased via the clear circuit 57.

In other words, the intrusion abnormality detection signal generated during the elapsed time from the cancellation activation to the predetermined time T2 is subjected to the cancellation action. In addition, if it is necessary to limit the number of cancellations of the intrusion abnormality detection signal generated during the fixed time T2 to, for example, one or two times, the limited number of times is set in advance in the count circuit 58, and the specified number of times is set in advance. Performs a canceling action for the number of times. Note that when a recovery signal is generated in the intrusion abnormality detector 1 or the battery is exhausted without waiting for a certain period of time T2 after cancel activation, the fourth flip-flop 55 outputs the recovery signal from the signal code discrimination circuit 29 to its reset terminal R. , the canceling action is stopped upon receiving a battery exhaustion signal. In other words, the restoration of the intrusion anomaly detector 1 means that the vigilance mode has been restored, at least in the night mode, and the canceling action is no longer necessary. In the embodiment, the audio output circuit 34 and the second L
The ED drive circuit 35 displays a detection signal that detects an intrusion abnormality via the buffer circuit 31, but a separate
Except for sending a signal to the sending circuit 33 when the signal code discrimination circuit 29 determines that there is an intrusion abnormality, the audio output circuit 34
Also, an abnormality may be displayed on the second LED drive circuit. however,
At this time, when the clear circuit 57 is activated, it sends out a clear signal to turn off the display.

As is clear from the above description, according to the present invention, when the cancellation activation device is operated by a person at home in a guarded area at home and in a manned state at night, the cancel activation device is activated for a certain period of time before and after the cancellation activation action. This cancels the intrusion abnormality detection signal that has occurred. In other words, if you inadvertently open a window and cause the anomaly detector to deactivate, you can cancel it, or if you consciously cancel the operation before opening the window, you can cancel it by opening the window. The intrusion abnormality detection signal is no longer reported to the management center via, for example, a transmitter.

Effects of the Invention - Since the intrusion abnormality detection signal for a certain period of time before the activation of the cancellation activation device can be canceled, it is possible to prevent false alarms due to operator's erroneous operation.

・One cancellation activation device can cancel intrusion anomaly detection signals of multiple intrusion anomaly detectors or selected intrusion anomaly detectors, resulting in simplicity and cost reduction.

・Unlike conventional security systems, there is no need to operate the cancellation activation device in order to restore the re-alert state to the restricted area; therefore, as long as the intrusion anomaly detector is restored, the re-alert state can be obtained. Since the person at home can confirm the restoration of the intrusion anomaly detector from the LED display, forgetting to be alert will not occur, and security accuracy will be improved.

Although the present invention has been described above with reference to a wireless one-way security system, it goes without saying that the present invention is also applicable to wired or two-way security systems.
