Description

Description of the Related Art [0002] Moving Compact Image Recording Control Method (Moving Type Compact Image Recording Unit and Control Method)

The present invention relates to a portable compact image recording control method, which enables a video recording apparatus to record an image in real time, and can output real-time image data through a monitor. Particularly, The power is supplied to the monitor only when it is necessary to perform the power saving operation, thereby eliminating waste of power.

Generally, a DVR (Digital Video Recorder), which is an abbreviation of a digital video recorder, captures a video signal inputted through a surveillance camera, converts the captured video signal into a high-quality digital video signal, stores it on a storage medium such as a hard disk or an optical disk The recorded video can be easily searched or played back by each time, date, as well as each camera and event, and it is easy to backup and edit. When a plurality of surveillance cameras are used, images input from respective surveillance cameras are displayed on one monitor screen A digital video storage device capable of semi-permanently using the recorded video, which is capable of performing a multiplexer function that can be divided and monitored, and is widely used in a large discount store, a parking lot, a financial institution, .

Recently, a lot of vehicles have been installed in buses, subways, patrol cars, and other vehicles in order to secure evidence for accidents such as traffic accidents and human accidents. Also, crimes are frequently occurred along with the speed of development of society. The demand for the installation of DVR is increasing as security equipment to do this.

In order to install the DVR in a limited space such as a car or a home, it is necessary to expand the DVR to be installed in the existing equipment such as a personal computer, the environmental factor such as the size of the DVR, vibration or impact, Maintenance, etc., should be considered. To reflect this, the following devices have been proposed and commercialized.

6 is a control block diagram of the present invention,

The portable compact recording apparatus 10 according to the present invention comprises a body 11 and a lid 12 and is coupled through a hinge 13 and receives an external camera image from the body 11 And a liquid crystal display 14 for displaying a photographed image in real time is mounted on the front surface of the lid 12. [

A recording device for recording real-time photographed contents is inserted in the front of the device, and the recording device is encrypted so that only a person having a special key can view it.

In addition, the photographed image is only output in real time, and when the cover 12 is covered, the image is not outputted to the outside, so that the power can be saved.

In addition, according to the present invention, the cover 12 is opened and the liquid crystal display is operated in a standby state. When it is determined that an operator or a person appears in the portable compact recording apparatus 10, power is supplied to the liquid crystal When the cover 12 is unfolded, a real-time image is output immediately.

Accordingly, the operator or the observer may cause an illusion that the liquid crystal display 14 is always on, and the reason for this is that the person reads the coming-in and only operates the liquid crystal display 14 This is because we stand by.

That is, when an animal or a child emerges, the liquid crystal display 14 is not powered, and the liquid crystal display 14 is standby when an adult of a certain size or weight appears.

To this end, the present invention comprises a control unit 200 for installing various sensor modules 100 capable of discriminating the appearance of a person in the portable compact recording apparatus 10 and outputting a control signal according to the sensing result of the sensor module 100, .

In addition, the present invention is characterized by a horizontal support unit 20 for supporting the compact recording apparatus 10 in a horizontal state, a vertical support unit 30 installed at the rear of the compact recording apparatus, and an upper support unit 40 And the sensor module is installed in front of the upper support portion 40 and the horizontal support portion 20. [

The sensor module 100 is composed of a weight sensor 110, an infrared sensor 120 and an ultrasonic sensor 130. The weight sensor 110 is installed in a carpet type and installed on the front of the portable compact recording apparatus. .

That is, the weight sensor 110 may be composed of a plurality of sensors disposed on the floor of the access road of the portable compact recording apparatus. The weight sensor 110 senses the bottom pressure of the access road to detect presence or absence of a person, .

The weight sensor 110 may be installed at a predetermined depth on the floor of the entrance area of the entrance of the portable compact recording apparatus where weight measurement is required, and the weight sensor may be installed directly on the installation groove.

The weight sensor 110 measures the weight of an object using a piezoelectric element that generates a voltage difference according to the pressure of the object. Of course, when a strain gauge is attached to a metal elastic body in place of the weight sensor, and when a load is applied to the elastic body, a load cell that outputs an electrical signal proportional to a magnitude of a load applied according to a change in resistance value of the strain gauge, A sensor can be used.

The infrared sensor 120 senses infrared light information of an object. There are quantum and thermal (thermal) types on the detection system. The quantum type senses light as a quantum by using the effects of photoconductive and photovoltaic power. Materials such as InSb and HgCdTe are used.

In other words, the infrared sensor 120 is configured to be output when it detects infrared rays. The infrared rays emitted from a human body or an animal body have a wavelength of about 10 um. When the infrared sensor 120 detects the wavelength, It is designed to react, so it can distinguish between living and non-living.

The ultrasonic sensor 130 measures the key from the bottom surface to discriminate between an animal and an adult. When the key is large, it senses that an adult exists. When the key is small, the ultrasonic sensor senses that there is an animal.

The controller 200 determines whether a person is present in the entrance of the recording apparatus according to the measured value of the sensor module 100. When it is determined that the person enters the entrance of the recording apparatus, the controller 200 applies power to the liquid crystal display Let the liquid crystal turn on.

Specifically, the control unit 200 determines a weight value when a person or an animal approaches the entryway of the recording apparatus, compares the weight value with a predetermined value, and when the comparison result measured value is less than the first set value, (Less than about 6 kg) is measured by the sensor module 100, it is determined that there is no person and power is not applied to the liquid crystal display.

On the other hand, when the weight value is used, it is difficult to distinguish between children and animals.

That is, in the case of a child with a small weight, there is not much difference between the animal and the animal. In this case, when the child stands, the animal is assumed to exist and the power is not applied to the liquid crystal display device.

In order to solve this problem, in the present invention, a key is measured using an ultrasonic sensor, and based on this, a child and an animal are separated from each other.

In this state, the transmitting and receiving ultrasonic sensor 130 periodically transmits the ultrasonic signal by the control unit 200 and the ultrasonic signal transmission driving unit 131, and the ultrasonic signal receiving and amplifying unit 132 transmits the ultrasonic signal to the predetermined object The controller 200 receives the ultrasound signals reflected by the ultrasound signals reflected by the viewer and inputs the ultrasound signals to the controller 200. The controller 200 calculates the distances between the liquid crystal display and the human being according to the well- .

As is well known, the frequency of the ultrasonic signal transmitted and received through the ultrasonic sensor 130 is 40 kHz, which is achieved by the ultrasonic signal transmission driver 131.

L = (T * V) / 2

L: Distance to the object (m)

T: Time until the ultrasonic signal is transmitted and the ultrasonic signal is received V: Sound velocity (m / s),

V = 331.5 + 0.6 * t

t: Celsius temperature

As a result, the present invention determines whether to apply power to the liquid crystal display by using three sensors, and applies power to the liquid crystal display only in a necessary situation.

That is, since the power of the liquid crystal display is turned on only when it is necessary to display the contents recorded in real time, the power can be saved as much as possible and used for a long time.

In addition, the present invention can be installed only by a person having a special key, not by a person who can view the recording apparatus, and can fulfill the supplementary function faithfully.

In addition, when the human body is sensed, the cover may be automatically opened to display the liquid crystal display. For this reason, if it is determined that the person is close to the compact recording apparatus 10 as a result of the operation of the sensor module 100, The rotation shaft 13b rotates, and the hinge structure 13c rotates in accordance with the rotation of the rotation shaft. The motor is fixed to the fixing means 13d so that the body is kept stationary without moving.

Accordingly, when the motor 13a is driven, only the rotating shaft 13b is rotated. In accordance with the rotation of the rotating shaft 13b, the hinge structure rotates, and the hinge structure 13c is engaged, Direction or counterclockwise to cause the compact imaging device 10 to close or open.
