The present invention relates to a security monitoring device, in particular, it is possible to more accurately determine the intrusion status of the intruder invading through the window, and to implement the wireless detection of the window detector to wirelessly send out the abnormality information of the detector to the security control device The present invention relates to a window guard monitoring device and a control method.

Conventionally, the conventional technique for detecting an intrusion of a window uses a method of combining a magnet sensor detecting a door opening and a glass sensor detecting glass breakage as a method for detecting an external intrusion penetrating through a window. It was.

1 is a block diagram showing the configuration of a window security monitoring apparatus using an infrared sensor according to the prior art.

Referring to FIG. 1, the infrared sensor for monitoring a window continuously emits and emits infrared rays, a light receiving unit 100, a light receiving unit 104 for receiving infrared light transmitted from the light transmitting unit 100, and reception of the light receiving unit 104. The detection unit 106 is configured to detect whether or not there is a certain period and to notify the security control unit 108 or the like of the detected data. Thus, the detection of the blockage due to an obstacle between the light transmitting unit 100 and the light receiving unit 104 to notify the abnormality. The security control unit 108 displays the abnormality data received by the detection unit 106 in the security control unit 108 by itself or performs an online notification to notify the intrusion abnormality of the window. However, since the infrared detector has a high current consumption due to the continuous infrared transmission of the light emitting unit 100 and a long distance of 10M or 20M or more, the purpose of the detection is economical as a detector for detecting a small window. There was no. In addition, the infrared detector has a large current consumption, so a separate power source must be configured or a power line for supplying input power must be provided.

In the prior art, the operation of the infrared sensor for monitoring the window, as shown in Figure 1 in the security control unit 108 to supply DC power to the infrared detector of the light emitting unit 100 and the light receiving unit 104 or a separate external power supply device It was configured to supply power to the infrared detector. The infrared detector which receives the input power from the security control unit 108 or a separate power supply device first generates infrared rays from the light transmitting unit 100 and forms the optical infrared rays on the light transmitting unit 100 to diffuse the beam. Two beams having straightness were simultaneously sent out while blocking the. In this case, the infrared rays transmitted are usually of a long distance type having a scanning distance of 10 M or more, and the two light beams are received by the light receiving unit 104 inside the receiver 102. When the beam is normally received within a certain time period, the light receiving unit 104 recognizes that it is normal and continues to wait for the next reception. The light receiver 104 may adjust the beam disconnection detection time. If the beam is not received for a predetermined time or more, the detection unit 106 determines this as an abnormality detection and notifies the state of abnormality to a contact point or the like. Therefore, such an abnormal state is detected by the security control unit 108 or the like and displayed on-line or notified online so that an intrusion abnormality has occurred in the monitoring area using the infrared detector.

In the prior art, the infrared detector configured as shown in FIG. 1 is a power generator or a separate power source of the control unit 108 for supplying power due to the high current consumption due to the emitter 100, which is an infrared ray generator continuously emits infrared light Since a large amount of current (approximately 35 mA per unit) must be supplied from the device, an increase in the capacity of the power supply device occurs, and in addition, the use of a wireless detector is increasing in order to prevent damage to the interior of the monitoring area and improve construction performance. Infrared sensor has a high current consumption, which makes it impossible to realize the wireless sensor by battery. In addition, the infrared detector is designed to control the entry and exit of restricted areas such as fences or doors. It is designed to detect long distances over 10M or 20M, so it is not economical to detect small windows. Judging. In addition, in places where the height to be regulated is more than 30cm, two or more detectors should be installed up and down to ensure perfect intrusion prevention. Therefore, several infrared detectors should be installed according to the height of the monitoring area. This situation is becoming.

In addition, the infrared detector can not set the detection propensity or the setting of the detection method except that it can adjust the detection time of the disconnection of the beam.In addition to detecting the intrusion of the intruder, the infrared sensor is equally ideal for blocking the beam between the transmitter and the receiver by an object. There is a problem that a lot of misinformation (detecting abnormality of intrusion outside the target of regulation, not actual intruder's intrusion) etc. occurs in the security control unit which should detect human intrusion.

An object of the present invention is to implement a detector having a judgment ability according to the inclination of the intruder to invade the window to detect whether the window intrusion more selectively against the intrusion of non-human objects or small animals to reduce the occurrence of misinformation. To provide a window security monitoring device and control method.

Another object of the present invention to provide a window guard and monitoring method that can reduce the amount of current consumption by transmitting and receiving a beam in a digital pulse method.

It is still another object of the present invention to provide a window security monitoring device and a control method capable of improving the aesthetics and construction of the product by configuring the window security detector as a wireless embedded sensor that does not require external wiring.

In order to achieve the above object, the present invention is a window guard monitoring device, the first foot is mounted on one side of the window frame of the window and is composed of a first pulse light emitting part, a second pulse light transmitting part at a predetermined interval. A second transmitter comprising a bride, a third pulse transmitter, and a fourth pulse transmitter, spaced apart from the first transmitter by a predetermined interval, and the other side of the window frame of the window corresponding to the first transmitter; A first receiver configured to be attached to the first pulse receiver and a second pulse receiver, and a second receiver configured to be mounted at a position corresponding to the second transmitter and configured to a third pulse receiver and a fourth pulse receiver; And a control unit that detects an output signal of the first and second receivers and accurately detects an intrusion state of a person according to an operation tendency of the person who intrudes through the window.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In describing the present invention, it should be noted that specific descriptions of well-known functions or configurations are omitted in order not to disturb the gist of the present invention.

With reference to the drawings will be described the configuration of the window security monitoring apparatus according to an embodiment of the present invention.

First, the present invention is a window guard monitoring device for detecting an intruder entering the window, rather than detecting a long distance such as a fence or door. The window guard monitoring apparatus of the present invention is configured by the net (NET) method of the window to transmit and receive a number of pulses and to implement a detector having a judgment ability according to the behavioral tendency of the person to the non-human objects or small animals By selectively monitoring for intrusions, you can reduce the occurrence of misinformation.

That is, according to the present invention, a detector for monitoring an intrusion abnormality of a window is monitored by a net method using a digital pulse of a low current consumption, and the intrusion of a person is determined more accurately by determining whether or not the intrusion is made according to a reception type. Judgment can reduce misinformation (detection of non-human small animals or objects). In addition, by configuring the power supplied to the detector with a small battery 306 to remove the separate power line or power supply for the power supply for the detector and to transmit the abnormality information of the detector to the security control unit 202 by wireless Characterized in that the wireless implementation of the window security monitoring device.

The configuration of the present invention is implemented by the net sensor installation configuration example as shown in Figure 2 and the net sensor internal configuration and operation as shown in FIG.

First, the net detector includes a controller 202, first and second transmitters 204 and 206, and first and second receivers 208 and 210. The control unit 202 is composed of a wireless transmission unit 302, the microcomputer 304, the battery 306. The first emitter 204 includes a first pulse light emitter 308 and a second pulse light emitter 310. The second emitter includes a third pulse projector 312 and a fourth pulse projector 314. The first receiver 208 is mounted at a position corresponding to the first transmitter 204 and includes a first pulse receiver 316 and a second pulse receiver 318. In addition, the second receiver 210 is mounted at a position corresponding to the second transmitter and includes a third pulse receiver 320 and a fourth pulse receiver 322.

The lengths of the first and second transmitters 204 and 206 are about 40 cm, and two pulse light emitters are spaced 20 cm apart inside each transmitter. The first and second receivers 208 and 210 have the same structure, and each of the receivers has two pulse receivers for transmitting and receiving pulses.

Each of the pulse light transmitting unit and the pulse light receiving unit is composed of one pair, and one or more pairs are used depending on the height of the window.

2 illustrates an example in which two sets of net detectors are installed around the window frame 200, and the first and second transmitters 204 and 206 on the left side of the window frame 200 transmit pulses under the control of the detection unit. The first and second receivers 208 and 210 on the right side of the window frame 200 are light receivers that receive the pulses transmitted from the first and second transmitters 204 and 206. The first and second transmitters 204 and 206 and the first and second receivers 208 and 210 are installed in parallel with each other. In addition, the controller 202 is configured to receive the pulse transmission control of the first and second transmitters 204 and 206 and whether the first and second receivers 208 and 210 receive the pulses.

The detailed configuration and operation of FIG. 2 is configured as shown in FIG.

The detailed configuration of the control unit 202 is composed of a microcomputer 304, a wireless transmitting unit 302, and a battery 306. The microcomputer 304 has a program mounted therein to perform an input / output control function. The wireless transmitter 302 wirelessly transmits an abnormal signal according to whether the microcomputer 304 detects an abnormality. The battery 306 functions to supply operating power for the microcomputer 304 and the wireless transmitter 302.

The program mounted on the microcomputer 304 is an algorithm for determining the intrusion abnormality by the input / output control of the microcomputer 304.

There are two methods of determining an intrusion abnormality: an abnormality detecting method in the individual steps in FIG. 4 and an abnormality detecting method in the two or more steps in FIG.

First, FIG. 4 continuously monitors when pulse reception is delayed or not in any one of pulse sending steps between the installed first and second transmitters 204 and 206 and the first and second receivers 208 and 210. If a certain period of time is delayed is an error monitoring method to determine the intrusion failure.

Meanwhile, FIG. 5 continuously monitors if pulse reception is delayed or not at two or more steps among pulse sending steps between the first and second transmitters 204 and 206 and the first and second receivers 208 and 210. When the time abnormality is delayed, it shows the abnormality monitoring method which judges it as an intrusion abnormality.

2 to 5 will be described in detail the operation of the window security monitoring apparatus according to an embodiment of the present invention.

FIG. 2 shows the first and second transmitters 204 and 206 on the left side of the window frame 200 and two pulse light receivers on the right side. The detailed structure and operation are configured as shown in FIG. 3. .

In FIG. 3, the microcomputer 304 has a program mounted therein, and has a signal output function of one clock (50 ms) at a predetermined period in the first, second, third, and fourth pulse light emitting units 308, 310, 312, and 314. Thus, one clock pulse is sequentially transmitted from the first pulse projector 308 to the fourth pulse projector 314. The pulse transmitted from the first pulse receiver 308 is received by the first pulse receiver 316, and the pulse transmitted from the second pulse receiver 310 is received by the second pulse receiver 318. The third and fourth pulse receivers 320 and 322 are received.

4 and 5 illustrate a method of detecting an abnormality of the net sensor, and the pulse transmission of the first pulse projector 308 is indicated by step 1, and the pulse transmission of the second pulse projector 310 is then sent. Step 2, the pulse transmission of the third pulse light projecting section 312 is shown in step 4, the pulse transmission of the fourth pulse light projecting section 314 is shown in step 4 to display the abnormal detection method of the microcomputer 304.

Receiving the signal of step 1 is the first pulse receiving unit 316, when the signal of step 1 is normally received by the first pulse receiving unit 316 without external interruption, the internal element (phototransistor) of the first pulse receiving unit 316 The digital high state when there is no reception is converted to the digital low state and output to the microcomputer 304. On the contrary, if the received signal of the first pulse receiving unit 316 is not received by the external cutoff, the digital high state is maintained. In the same manner, the second pulse receiver 318 receives the signal of step 2 output from the second pulse receiver 310 and receives the digital low or digital high state in the same manner as the first pulse receiver 316. Output to the microcomputer 304. Subsequently, the digital low or digital high state applied to the N-th pulse receiving unit 500 is output to the microcomputer 304.

The intrusion failure detection method using this operation is illustrated in two cases, the abnormal detection method in the individual steps of FIG. 4 and the abnormal detection method in two or more steps of FIG. 5.

In the case of FIG. 4, the signal of step 1 is transmitted from the first pulse light emitter 308 under the control of the microcomputer 304, but the transmitted pulse was not received by the first pulse light receiver 316 due to an external cutoff. At this time, the microcomputer 304 transmits the signal of step 1 from the first pulse transmitter 308 during the reception standby time at the same time as the step 2 signal transmission from the second pulse transmitter 310 and the first pulse receiver 316. Rediscover the reception. If the reception is not continued, the signal retransmission continues during the reception standby time. If the signal is received within this time, the signal retransmission stops and is sent in the next cycle (signal transmission cycle). Subsequently, pulses are sent to the pulse projecting portion N provided. When the pulse transmission is completed sequentially from the first pulse light emitter 308 to the Nth pulse light emitter 400, the pulse is transmitted again from the first pulse light emitter 308.

At this time, the abnormality detection method is determined according to the reception waiting time, and the reception waiting time is set to the minimum time (about 500 ms) for a person to pass through the detector. That is, if reception is made within this time, it is determined as a misreport (detection of non-human small animals or fallen leaves, rainwater, etc.) and is not detected as an abnormality. If abnormality is detected after this time, it is determined as an intrusion abnormality. The microcomputer 304 transmits the intrusion abnormality signal wirelessly to the security control apparatus through the wireless transmission unit 302 and transmits the security abnormality to the security control apparatus so that the security control apparatus displays the intrusion abnormality by itself or transmits it online.

In the case of FIG. 5, the first pulse transmitter 308 transmits the signal of step 1 under the control of the microcomputer 304, but the transmitted pulse was not received by the first pulse receiver 316 due to external interruption. The microcomputer 304 retransmitted the signal of step 1 from the first pulse transmitter 308 during the reception standby time at the same time as the step 2 signal transmission from the second pulse projector 310. Since the sending signal of 310 is not received by the second pulse receiving unit 318, the signal of steps 1 and 2 is re-sent simultaneously with the sending of the signal of step 3. If the signal reception of step 1 and step 2 is not continued in each of the first pulse receiving unit 316 and the second pulse receiving unit 318, the signal retransmission continues during the reception standby time and the signal retransmission is received within this time. Stops and is sent out in the next cycle (signaling cycle). Subsequently, pulses are sent to the N-th pulse light transmitting unit 400 provided therein.

When the pulse transmission is completed sequentially from the first pulse light emitter 308 to the Nth pulse light emitter 400, the pulse is transmitted again from the first pulse light emitter 308.

At this time, the abnormality detection method detects an abnormality in two or more steps, and determines that the intrusion is abnormal when the reception waiting time is 200 ms or more (minimum time that a person bends and passes). However, if reception is made within this time, it is determined as a misreport (a detection of non-human small animals or fallen leaves, rainwater, etc.) and is not detected as an intrusion abnormality. The abnormality detected intrusion abnormality signal is wirelessly transmitted to the security control apparatus through the wireless transmitter 302 so that the security control apparatus displays the intrusion abnormality by itself or transmits it online. The operating power of the microcomputer 304 and the wireless transmitter 302 is supplied from the battery 306 to operate, and the microcomputer 304 has a structure in which the sleep (SLEEP stoppage) and wake-up operation are repeated. To minimize the operating current consumption.

As described above, the window guard monitoring apparatus and control method according to an embodiment of the present invention can reduce the misinformation by monitoring the entry of objects or small animals through the window more selectively, and transmit and receive pulses with only a small battery As a result, the current consumption can be reduced, and the wiring can be reduced, and the aesthetics and workability can be improved by configuring the wireless embedded sensor.
