Description

  The present invention relates to an intrusion detection system.

Conventionally, intrusion detection that emits an alarm by detecting that an intruder (detection target person) has intruded based on the reflected wave by emitting a detection wave such as infrared rays, ultrasonic waves, and microwaves into a predetermined alert area. A system is known, and in such a system, a device that enables on / off control of human body detection by a human body detection sensor unit by transmitting a signal from a portable remote control device has been proposed (for example, Patent Documents). 1).
JP 2000-99836 A (paragraphs 0022 to 0025 and FIG. 1)

  However, in the one described in Patent Document 1, if it is forgotten to transmit an off signal of the intrusion determination operation from the portable remote control device before intruding into the alert area, it is assumed that the intruder is not an intruder. It may be judged and an alarm may be issued.

  An object of the present invention is to provide an intrusion detection system in which an intrusion determination operation is automatically stopped or temporarily stopped only by holding a portable remote controller when entering a warning area, thereby preventing a malfunction. To do.

  According to the first aspect of the present invention, an intrusion determination apparatus that performs an intrusion determination operation for emitting a detection wave in a predetermined alert area and receiving the reflected wave to determine whether or not an intruder exists in the alert area. And an intrusion detection system that can transmit a cancel signal that stops or temporarily stops the intrusion determination operation to the intrusion determination device, wherein the mobile remote control device detects from the intrusion determination device. Detection wave presence determination means for determining presence / absence of a wave, and a signal from the detection wave presence determination means, and when the detection wave is determined to exist, the cancel signal is output to the intrusion determination device And a cancel signal output means. Here, infrared waves, ultrasonic waves, microwaves, or the like are used as the detection waves. When a microwave is used as a detection wave, the microwave has a property of passing through clothes, so that an intrusion determination operation can be performed even when the portable remote control device is carried in a clothes pocket.

  In this way, since the detection wave is normally emitted from the intrusion determination device to the outside of the predetermined warning area, just by holding the portable remote control device, the detection wave presence determination means in the vicinity of the warning area. It is determined that a detection wave exists, and a cancel signal is transmitted to the intrusion determination device by the cancel signal output unit. As a result, the intrusion determination device does not perform the intrusion determination operation. Therefore, even if a non-detection target person with a portable remote control device enters the predetermined alert area, it is determined as an intruder (detection target person). There is no.

  As described in claim 2, the intrusion determination device emits a detection wave in a predetermined warning area, receives a reflected wave from the detection sensor unit, and receives a signal from the detection sensor unit. An intrusion determination means for performing an intrusion determination operation for determining whether or not an intruder exists in the mobile station, and a cancel signal from the portable remote control device when the intrusion determination means determines that an intruder exists in the alert area Signal confirmation means for confirming the presence or absence of, the intrusion determination means receives a signal from the signal confirmation means, and when the cancel signal is confirmed, the intrusion determination operation is stopped or temporarily stopped, If the cancel signal is not confirmed, it is desirable to output an intruder detection signal.

  In this way, when the intrusion determination unit determines that there is an intruder in the alert area, the intruder is not immediately determined to be an intruder, but the presence or absence of a cancel signal from the mobile remote control device is confirmed, and the cancel is performed. If the signal is confirmed, it is presumed that the person is not an intruder, so the intrusion detection operation is stopped or paused. On the other hand, if the confirmation is not confirmed, the intruder is detected and an intruder detection signal is output. Therefore, it is possible to reliably determine whether there is an intruder. When the intruder detection signal is output, an alarm or the like is output to notify that there is an intruder.

  According to a third aspect of the present invention, it is desirable that the detection wave presence determining means stop or temporarily stop the operation for determining the presence or absence of the detection wave when the detection wave is detected.

  In this way, when the detected wave presence determining means (portable remote control device) detects the presence of the detected wave, it is considered that it is not necessary to determine whether the detected wave exists for a while. Power saving for the portable remote control device can be achieved by stopping or temporarily stopping the operation of determining whether or not there is a detected wave.

  As described in claim 4, it is preferable that the stop or pause of the intrusion determination operation includes a stop or pause of the detection wave emission.

  In this way, it is possible to save power by stopping or temporarily stopping the emission of the detection wave. Here, the reason why the detection wave can be stopped or paused is that it is considered unnecessary to emit the detection wave when the intrusion determination operation is stopped or paused.

  According to a fifth aspect of the present invention, the portable remote control device may be configured to be able to transmit the cancel signal by manual operation of a remote control button.

  In this way, various operations regarding the intrusion determination operation can be performed by manual operation of the remote control button.

  In the present invention, since the detection wave is normally emitted from the intrusion determination device to the outside of the predetermined warning area, if the portable remote control device is provided, the detection wave presence determination means near the warning area has the detection wave. Since the cancel signal output means automatically transmits the cancel signal to the intrusion determination device, the intrusion determination device does not perform the intrusion determination operation, and the person with the portable remote control device can Even if it enters into the alert area, it is possible to avoid being determined as an intruder. Therefore, it is possible to reliably prevent an intrusion determination malfunction.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The intrusion detection system according to the present invention is an intrusion that performs an intrusion determination operation that emits a detection wave in a predetermined alert area and receives the reflected wave to determine whether or not an intruder exists in the alert area. A determination apparatus and a portable remote control device capable of transmitting a cancel signal for stopping or temporarily stopping the intrusion determination operation to the intrusion determination apparatus, and a schematic configuration of an embodiment of the intrusion determination apparatus FIG. 1 shows a schematic configuration of an embodiment of the portable remote controller, and FIG.

  As shown in FIG. 1, the intrusion determination device U1 includes a detection sensor unit 1 using the Doppler effect using a microwave as an active human body detection sensor, and this unit 1 is a micro wave as a detection wave in a predetermined warning area. 1 A of transmission parts which emit a wave, and the receiving part 1B which receives the reflected wave of the microwave are provided.

  Microwaves are emitted in a wide range from the transmission unit 1A toward the warning area in front of the unit, and the reflected waves (of the microwaves) received by the reception unit 1B pass through the amplification unit 2 and the signal processing unit 3, and then are microcomputers. To the intrusion determination means 5A of the control means 5 comprising In this intrusion determination means 5A, an intrusion determination operation for determining whether there is an intruder in the alert area is performed. When an intruder exists in the alert area, an intruder detection signal is sent to the alarm unit 6 and an alarm is output.

  In addition, a signal from the portable remote control device U2 is input to the control unit 5 through the antenna 7 and the receiving unit 8, and necessary processing is performed in the control unit 5 as described later based on the signal.

  The portable remote control device U2 has a function of detecting microwaves and is configured as shown in FIG.

  As shown in FIG. 2, the remote control device U2 is necessary to receive a microwave determination unit 11 that determines the presence or absence of a microwave, that is, whether or not a microwave exists, and a determination result from the microwave determination unit 11. Remote control means 12 (microcomputer) for performing various processes. Here, the necessary processing in the remote controller control means 12 is, for example, a remote control transmission unit that sends a cancel signal to the detection sensor unit 1 when the intrusion determination means 5A does not perform the intrusion determination operation when it is determined that microwaves are present. 13 through the antenna 14. For this purpose, the remote control means 12 of the portable remote controller U2 receives a detection wave presence determination means 12A for determining the presence or absence of a detection wave from the detection sensor unit 1, and a signal from the detection wave presence determination means 12A. And a cancel signal output means 12B for outputting the cancel signal to the intrusion determination means 5A when it is determined that the detected wave is present. The remote control means 12 also receives an operation signal from the remote control button 16 such as warning ON, warning OFF, alarm stop, etc., so that the alarm can be turned ON / OFF and other controls can be performed manually. The microwave determination unit 11 includes an antenna 11A, an amplification unit 11B, a detection unit 11C, and a determination unit 11D.

  The microwave determination unit 11 intermittently performs a determination operation at every elapse of a predetermined time. When the microwave determination unit 11 approaches a warning area where the microwave is emitted, the microwave determination unit 11 detects the microwave, and the microwave is detected. Detection information is input to the remote control means 12.

  When receiving the information, the remote controller 12 operates the transmitter 13 to transmit information data indicating that the person is an intruder.

  In addition, the control means 5 on the intrusion determination device U1 side receives a cancel signal from the mobile remote control device U2 when the intrusion determination means 5A determines that there is an intruder in the alert area in relation to the mobile remote control device U2. The signal confirmation means 5B which confirms the presence or absence of is provided. When the intrusion determination unit 5A receives the signal from the signal confirmation unit 5B and confirms the cancel signal, the intrusion determination operation is stopped or temporarily stopped. On the other hand, when the cancel signal is not confirmed, the intruder The detection signal is output to the alarm unit 6. Here, the stop or temporary stop of the intrusion determination operation includes stop or temporary stop of the detection wave emission from the detection sensor unit 1.

Next, the flow of processing in the intrusion determination device U1 will be described with reference to FIG. 3, and the flow of processing in the portable remote controller U2 will be described with reference to FIG.
(Intrusion determination device U1)
As shown in FIG. 3, when started, the transmission unit 1A and the reception unit 1B of microwaves (10.5 GHz (X band) and 24.2 GHz (K band)) of the detection sensor unit 1 start operation (step S1). ). Then, it is determined whether or not a moving object has been detected (step S2).

  That is, a moving object is detected using the Doppler effect. Transmits (fires) microwaves and receives their reflections. If there is a moving object in the alert area where the microwave is emitted, the frequency shift of the reflected wave differs depending on the moving speed of the moving moving object, and whether there is a moving object by detecting the deviation Determine.

  When the presence of a moving object is detected, there is no need for detection for a while, so the operation of the microwave transmitter 1A and the receiver 1B is stopped to save power (step S3). Therefore, the intrusion determination operation for the moving object into the alert area is not performed.

  Then, it is determined whether there is data received from the remote control transmission unit 13 of the portable remote control device U2 (step S4). Here, “there is reception data” means information from the remote control transmission unit 13 that the moving object (non-detection target person) is in the warning area or approaching the warning area.

  When there is no received data, the moving object is not an undetected person but an intruder, and therefore an intruder detection signal is sent to the alarm unit 6. That is, since there is no information indicating that a moving object has entered the warning area and that the moving object is in the warning area or approaching the warning area from the remote control transmitter 13, the moving object is not in the portable remote control device U2. It is thought that this is an intrusion by an intruder. Therefore, an alarm is activated for notification (step S5), and the process returns to the start (or ends as it is).

  If no moving object is detected in step S2, it is then determined whether there is data received from the remote control transmitter 13 (step S6). If there is received data, it is determined whether there is non-detection target person information (step S7). On the other hand, if there is no received data, the process returns to the start and the intrusion determination operation is continued.

In step S7, if there is non-detection target person information, the non-detection target person exists in the alert area, and it is not necessary to perform the intrusion determination operation for a while. Therefore, in order to shift to an intermittent operation for reducing power consumption, the operation of the microwave transmitter 1A and the receiver 1B is stopped for a certain period (step S8), and the process returns to the start. If there is no non-detection target person information, since the received data is data of the remote control button 16, the content of the pressed remote control button 16 is processed (step S9), and the process returns to the start. Here, the contents of the remote control button 16 are the above-mentioned (i) warning ON-OFF (ii) temporary stop of warning (automatically turns on after a certain period of time) (iii) stop / operation of intrusion determination operation (iv) Others.
(Portable remote control device U1)
As shown in FIG. 4, when starting, it is first determined whether or not the remote control button 16 of the remote control device U2 has been pressed (step S11). That is, it is determined whether each control such as warning ON-OFF of the microwave human body detection sensor unit 1 is performed by manually operating the remote controller U2.

  If the remote control button 16 has not been pressed, the microwave determination unit 11 is activated (step S12), and it is determined whether or not the microwave emitted from the microwave human body detection sensor unit 1 is detected (step S13). On the other hand, if it is pressed, the remote control transmitter 13 operates (step S14), and the content data of the pressed remote control button 16 is input to the remote control transmitter 13 (step S15). Is transmitted (step S16), and the process returns to the start.

  Here, in steps S14 to S16, data information is transmitted to the microwave human body detection sensor unit 1 by radio waves (for example, 430 MHz) in order to notify the microwave human body detection sensor unit 1 of the remote control content by manual operation. Is.

  If it is determined in step S13 that microwaves have been detected, it is within the alert area or in the vicinity of the alert area. Note that the microwaves are intermittently emitted, for example, at intervals of 1 second, or modulated such that the emitted microwaves are intermittently pulsed, and are distinguished from other microwaves. Has been made.

  If it is determined in step S13 that the microwave is not detected, the microwave determination unit 11 is stopped for a certain period (step S17). That is, in order to reduce battery consumption, the operation shifts to an intermittent operation in which microwave detection by the microwave determination unit 11 is repeated at regular intervals. On the other hand, if it is determined that the microwave is detected, the microwave determination unit 11 is stopped for power saving (step S18). Then, in order to notify the intrusion determination device U1 that the moving object that enters the detection area is not an intruder but a non-detection target person, the remote control transmission unit 13 is operated (step S19). ), The data of the non-detection target person is input to the remote control transmitter 13 (step S20), the process proceeds to step S16 to execute data transmission, and the process returns to step S11. Thereby, it is avoided that the intrusion determination apparatus U1 activates an alarm.

  In the embodiment, the remote control device U2 is provided with the remote control button 16. However, the present invention is not limited to this, and it is not provided with such a remote control button, and it is determined that the detected wave exists. Further, it may be configured to have a function of only outputting the cancel signal to the intrusion determination device. In that case, the processes of step S9 in FIG. 3 and steps S11, S14, and S15 in FIG. 4 are omitted.
