Description

Intelligent security apparatus

The present invention relates to a security device, and to an intelligent security device for sensing or photographing the surrounding sensing object.

Thanks to technological advancements in various electronic fields, such as sensor technology, image processing technology, and signal processing technology, technologies related to unmanned security systems are also being updated day by day.

In such an unmanned security system, various types of sensors are used to detect the movement of a sensing object such as an object, a person, or an animal.

Among them, motion sensors that detect the movement of an object are typically infrared sensors, ultrasonic sensors, and microwave sensors.

An infrared sensor is a sensor that detects heat radiated from the surroundings and converts electricity into a signal. Therefore, it can be referred to as a kind of transducer, and uses a principle of detecting a change in an object caused by an increase in the temperature of the material by infrared rays incident from a subject.

It is applied in various forms in everyday life such as intrusion alarm, automatic door, toilet bowl for men, lighting, and object detector in the rear of a car.

In the case of an infrared sensor, the sensitivity is the best when the object with the temperature difference is close to the sensor moves, but once the object is close enough to warm the ambient temperature, the sensitivity drops sharply. Therefore, in the case of summer, because the ambient temperature is similar to the human body, more malfunctions than in winter. In addition, the use of shields that move slowly or prevent heat can reduce sensitivity. Umbrella can also be used to neutralize infrared sensors.

An ultrasonic sensor is a sensor that calculates the presence and distance of an object by transmitting an ultrasonic pulse, which is a single frequency having a band of 40 to 250 KHz, which cannot be heard by the human ear, and then detecting an ultrasonic signal of the same frequency reflected on the object. In the case of an ultrasonic sensor, it detects a relatively long distance, and the sensing distance can be adjusted. It can be detected regardless of the material and color, but the sensor is slow and affected by the environment such as temperature and dust.

Microwave sensors are sensors that can compensate for the problems of infrared and ultrasonic sensors. The operating principle of the microwave sensor is that the frequency of the signal changes in proportion to the speed of the object due to the Doppler effect when the microwave signal is reflected by a moving object. The frequency of the signal reflected from a moving object with a constant period remains the same, but the phase changes over time.

The advantages of the microwave sensor are good straightness, long sensing distance and fast response. In particular, there is no malfunction due to heat and there is no significant effect on the surrounding environment such as dust and noise. It reacts precisely even at night when there is no light, and it also penetrates the walls except metallic. Because of these advantages, the system development using small radar is actively progressed when it is utilized in many application fields.

In terms of sensitivity, the infrared sensor is a passive type that senses heat from an object that emits heat, so the sensitivity is determined at the receiver.However, ultrasonic sensors and microwave sensors are sensitive not only to the sensitivity of the receiver but also to the higher transmit power of the transmitter. Therefore, when the performance of the sensing means is improved, the ultrasonic sensor and the microwave sensor become as sensitive as they are.

In terms of structure, the structure of the infrared sensor, which is dedicated to reception, is relatively simple, so that a low-cost product can be realized. However, the infrared sensor for detecting the temperature difference between the surrounding temperature and the moving object has a problem that a lot of errors may occur depending on the surrounding environment. Ultrasonic sensor as a sensing means with more improved performance has a problem in that it is not suitable for application to the consumer market at an economical price due to its complicated structure.

The present invention has been made to solve the above-described problems, and an object thereof is to provide an intelligent security device that can detect a sensing object more precisely and efficiently by using various sensors.

The illuminance sensor 113 is used to control the light emitting device according to the illuminance of the surrounding environment, and may be implemented using an LED or an IR-LED to improve the low illuminance sensitivity of the photographing unit 110.

The image sensor 114 photographs a subject. In detail, the image sensor 114 converts and outputs an optical image input through an external lens into an electrical signal, and photographs a subject under the control of the image sensor controller 116 and transmits the image to the storage 120.

The image sensor 114 may be implemented as any one of a CCD image sensor and a CMOS image sensor. Among them, CMOS image sensor has simpler driving method than CCD image sensor used in most CCTVs, and it is possible to integrate the module in one chip, so that the module can be miniaturized and the manufacturing cost can be lowered. .

The light emitting unit 115 may be implemented as an LED or an infrared LED, and outputs an LED or an infrared LED light source to the outside. In addition, the light emitting unit 115 receives various sensed signals of the Mosen detection sensor 111 and drives the light source of the LED light or the infrared LED used at night based on the value of the illumination sensor 113. .

The image sensor controller 116 controls the driving of the image sensor 114 and outputs an image acquired through the image sensor 114 to the storage unit 120.

In addition, the image sensor controller 116 may select which of LED lighting and infrared LED lighting is applied.

The storage unit 120 stores the image output from the photographing unit 110. In detail, the storage unit 120 may be implemented as at least one of a DVR, an NVR, and a server storing an analog or digital image.

As an example, the security device 100 may be a CCTV that can monitor the surroundings.

In addition, the security device 100 may build-in the module of the motion detection sensor 111 in the image capturing unit 110, and accordingly, the manufacturing cost may be significantly reduced with the miniaturization and weight reduction. .

According to an embodiment of the present invention, when the presence or absence of a subject is detected by the motion detection sensor 111, the image captured by the image sensor 114 is stored in the DVR, and a still picture and a text message are sent to the mobile phone of the control agent. The system can send alerts using the two-way voice transmission and reception function, if necessary, to detect external sensing objects quickly, accurately and smartly.

2 is a diagram illustrating a security device according to another embodiment of the present invention. Referring to FIG. 2, the security apparatus 1000 includes a sensing object sensing unit 200, an image capturing unit 300, a driving unit 350, an audio recording unit 400, a user input unit 500, and a time information receiving unit 600. , A communication unit 700, a storage unit 800, and a control unit 900.

The sensing object sensing unit 200 senses an environment around the security device 1000.

The sensing object sensing unit 200 includes at least one of an infrared sensor 210, an ultrasonic sensor 220, and a microwave sensor 230.

The sensing object sensing unit 200 may correspond to the motion detection sensor 111 of FIG. 1.

For example, when the sensing unit 200 includes all of the infrared sensor 210, the ultrasonic sensor 220, and the microwave sensor 230, some of all sensors may selectively operate. Alternatively, all or some of each sensor may operate sequentially to compensate for the shortcomings of each sensor. Accordingly, the security device 1000 may monitor the surrounding environment more efficiently, precisely, and smartly.

As another example, the security device 1000 may sense the sensing object using only the microwave sensor 230. This eliminates errors caused by temperature and humidity during motion detection, extends the detection distance and widens the viewing angle to perform motion detection in a wide range of areas, and transmits through obstacles such as walls within the detection distance. Motion can be detected.

The temperature sensor 240 detects the ambient temperature. The security device 1000 may control a signal applied from the infrared sensor 210 to the controller 900 according to the ambient temperature detected by the temperature sensor 240.

As an example, if the ambient temperature is 30 degrees Celsius, there is little difference in the temperature of the surrounding facilities and the temperature of the person may cause a situation that the operation of the infrared sensor is not efficient. Therefore, in this case, the control unit 900 may block a signal applied from the infrared sensor 210 to the control unit 900 under control, or may turn on / off the operation of the infrared sensor 210 itself.

Here, the preset temperature such as 30 degrees is preferably set in advance at the time of product launch, but may be arbitrarily set by the user through the user input unit 500.

The illuminance sensor 250 measures the brightness of the surroundings.

As an example, when the night is dark and the surroundings are dark, the visual signal input through the image capturing unit 300 may be useless, and the controller 900 may be controlled from the illumination sensor 250 under the control of the controller 250. By cutting off the signal applied to) or by turning off the operation of the illumination sensor 250 itself, power consumption can be reduced.

The image capturing unit 300 captures an image of the surrounding environment.

As an example, the image capturing unit 300 may capture an image at 3:00 in the form of a still image, and capture an image after 1 second in the form of a still image, and store each image in the storage unit 800. Through this, the image capturing unit 300 may detect the sensing object by comparing the current image with the previous image (or the current image and the future image).

The image capturing unit 300 may divide each still image into a plurality of regions and perform the above-described comparison operation for each region to accurately detect the sensing object.

Meanwhile, various known image analysis methods may be used to precisely detect the sensing object in the image capturing unit 300.

The driver 350 controls the movement of the image capturing unit 300. In more detail, the driving unit 350 may move the image capturing unit 300 up, down, left, or right, or rotate in one direction or a plurality of directions, and according to the movement pattern stored in the storage unit 800, the image capturing unit 300 may be moved. You can move it. The driver 350 may be electrically or mechanically implemented using a motor, an actuator, or the like.

The voice recorder 400 may receive and record the voice or sound measured in the vicinity. Accordingly, when it is determined that a voice of a predetermined level or more is received, the controller 900 may control the driver 350 to move the image capturing unit 300 to a location where the voice is received.

The user input unit 500 may input various setting information of the user. To this end, the user input unit 500 may include various types of operation buttons, operation keys, and the like. Furthermore, the user input unit 500 may include an LCD window having a touch screen function.

The time information receiver 600 receives current time information. As an example, the time information receiver 600 may receive current time information from the outside through the communication unit. As another example, the time information receiver 600 may be implemented as a GPS receiver. In this case, the time information receiver 600 may receive current time information from an external GPS.

The communication unit 700 may communicate with an external server (not shown) or an AP (not shown). Accordingly, information such as an alarm message can be transmitted to an external server (not shown). Alternatively, the communication unit 700 may be implemented to enable remote control of an external server (not shown) through the control unit 900 by receiving a remote control signal through an external server (not shown) and transmitting the signal to the control unit 900. have.

The communication unit 700 is preferably implemented to enable wireless communication such as a 3G communication network, a WiFi communication network, a Wibro communication network, and a local area communication network, but may also be implemented to enable wired communication using a LAN or the like.

The storage unit 800 may include a sensed signal of the sensing unit 200, ambient temperature information of the temperature sensor 240, ambient brightness information of the illuminance sensor 250, image information captured by the image capturing unit 300, Received by the voice information received from the voice recorder 400, various setting information of the user input 500, an alarm message to be transmitted from the control unit 900 to an external server (not shown), image, video information, time information receiving unit 600 Various signals or information, such as current time information.

The controller 900 blocks a signal input from the infrared sensor 210 when the sensed ambient temperature is greater than or equal to a preset threshold, and detects the signal using the signals input from the ultrasonic sensor 220 and the microwave sensor 230, respectively. Identify the water.

The controller 900 identifies the sensing object by analyzing the image photographed by the image capturing unit 300.

The controller 900 classifies the image photographed by the image capturing unit 300 into a plurality of regions, and identifies the sensing object by comparing the previous time image and the current time image for each divided region.

If it is determined that the preset condition is satisfied according to the sensing object identification, the controller 900 controls the communication unit 700 to generate an alert message and transmit the alert message to an external server (not shown). In this case, the preset condition is satisfied when it is determined that the sensing object is detected by both the ultrasonic sensor 220 and the microwave sensor 230.

Therefore, when one of the ultrasonic sensor 200 and the microwave sensor 230 determines that the sensing object is not detected, since the alarm message is not transmitted to an external server (not shown), the sensing efficiency of the sensing object may be improved. It can be higher.

On the other hand, when it is determined that the sensing object is detected, it means that the signal applied from each sensor is significantly changed compared to the normal operation signal, and the sensing object is detected when the change is more than the preset value May be set. In addition, as a result of analyzing the image in the image capturing unit 300, it may be determined that the sensing object is detected when the difference in the pixel value of the specific region is significantly changed between the current image and the previous image.

The controller 900 blocks a signal input from the image capturing unit 300 when the measured ambient brightness is equal to or less than a preset value.

The controller 900 moves the image capturing unit 300 to the first position when the first time set according to the user command of the user input unit 500 arrives, and removes the image capturing unit 300 when the second time arrives. The driving unit 350 is controlled to move to the two positions.

As an example, when the security device 1000 monitors each of the two garages, the homeowner's work time is generally between 5 am and 6 am, and the homeowner's work time is generally between 8 am and 9 am. If the time, the controller 900 controls the driving unit 350 so that the image photographing unit 300 faces the garage door of house A when 5 am arrives, and the image photographing unit 300 is B when 8 am arrives. The driving unit 350 may be controlled to face the garage door of the house. Accordingly, the security device 1000 may increase user convenience.

The controller 900 controls the driving unit 350 to move the image capturing unit 300 in a direction in which the surrounding voice is uttered when the surrounding voice of the voice recording unit 400 is equal to or greater than a preset threshold.

The control unit 900 generates an alarm message and transmits an alarm message to an external server (not shown) when it is determined in the user input unit 500 that the first color set according to a user command is greater than or equal to a preset range of the plurality of areas. Control 700.

As an example, when the red ratio is 20% or more of the still images among the images captured by the user input unit 500, when the alarm message is set to output an alarm message, the person wearing the red top and the bottom is the image taking unit 300. When confirmed through), the control unit 900 may control the communication unit 700 to transmit an alert message to an external server (not shown).

Security device 1000 according to another embodiment of the present invention includes an infrared sensor 210, an ultrasonic sensor 220, and a microwave sensor 230, the sensing object sensing unit 200 for sensing a sensing object, Movement of the temperature sensor 240 for sensing the ambient temperature, the illuminance sensor 250 for measuring the ambient brightness, the user input unit 500 for receiving a user command, the time information receiver 600 for receiving current time information, and the image capturing unit Input unit from the driving unit 350 for controlling, the voice recording unit 400 for receiving and storing the surrounding voice, the communication unit 700 for communicating with an external server, the image capturing unit 300 for photographing the sensing object, and the sensing object sensing unit And a controller 900 for identifying the sensing object based on the detected signal, and when it is determined that a predetermined condition is satisfied according to the sensing object identification, the controller 900 generates an alarm message to an external server (not shown). Communicate to Send Alert Messages The controller 700 controls the unit 700 and the predetermined condition is satisfied when it is determined that the sensing object is detected by both the ultrasonic sensor 220 and the microwave sensor 230.

The security device 1000 according to another embodiment of the present invention differs only from the security device 1000 according to an embodiment of the present invention, and its operation principle is the same. Description of the description will be omitted.

On the other hand, the security device 1000, in order to implement an intelligent unmanned surveillance CCTV system in the future, it is possible to stably increase the detection recognition rate in a poor environment and is compatible with interlocked systems such as a camera controller such as a storage device, camera pan / tilt, zoom in / zoom out, etc. It can be designed to work well.

3 is a diagram illustrating a microwave sensor according to an exemplary embodiment. Referring to FIG. 3, the microwave sensor 230 includes an oscillator 231, a transmitting antenna 232, a receiving antenna 233, a mixer 234, an amplifier 235, and an output terminal 236.

The oscillator 231 generates a high frequency signal and may be implemented as an oscillator. In addition, the oscillator 231 may include an amplifier for amplifying the generated high frequency signal.

The transmit antenna 232 radiates the generated high frequency signal or the amplified high frequency signal to the outside.

The receiving antenna 233 receives the reflected wave reflected on the surrounding sensing object. The frequency of the reflected wave is generally smaller than the emitted frequency.

The mixer 234 synthesizes the emitted high frequency signal and the signal reflected by the sensing object.

The amplifier 235 generates a converted signal by converting from the frequency synthesized in the mixer 234 to the frequency of the intermediate band IF, and amplifies the generated converted signal.

The output terminal 236 outputs the amplified converted signal.

Specifically, the transmission frequency of the oscillator 231 propagates in the air through the transmission antenna 232, and the radio wave is reflected from the moving object and received by the reception antenna 233. The reception frequency is input to the mixer 234 and mixed with the fine transmission frequency introduced into the mixer 234 to detect the subject's detection frequency (IF = Ft-Fr) by the difference between the transmission frequency Ft and the reception frequency Fr. Is detected. The IF frequency increases when the subject approaches the sensor, and the IF frequency decreases when the subject moves away from the sensor. This principle is the Doppler effect, which is used as a signal to amplify this detection frequency to drive the built-in sensor relay, and generate a sensor detection signal with the relay switch ON / OFF.

The microwave sensor 230 has an average detection range of 20 meters and a wider detection range than a general sensor, and is not influenced by natural factors such as light or ambient temperature. Therefore, the microwave sensor 230 can realize a miniaturization and a light weight with a simple circuit configuration while maintaining improved performance, so that the cost-performance ratio is good.

In addition, since the microwave sensor 230 has a long sensing distance and a wide sensing angle, there is no malfunction in temperature, humidity, and noise. In addition, the microwave sensor 230 is an X-BAND electromagnetic wave sensor, the motion detection is delicate, may penetrate the wall except for metallicity. Accordingly, the microwave sensor 230 transmits a signal to the alarm device when the subject is present for crime prevention for intrusion monitoring, power saving management of parking lot lights, automatic door access detection device, automatic ON / OFF of apartment entrance or basement lights, and automatic escalator operation. It is actively used in various fields such as SYSTEM.
