Controlling device of VCR for a surveillance camera recording

The present invention relates to a control apparatus of a video cassette recorder for recording a surveillance camera, and more particularly, a video cassette recorder for recording a surveillance camera capable of controlling the recording to a general video cassette recorder only when a surveillance situation occurs in the surrounding environment. It is about the control of the.

In general, surveillance systems using surveillance cameras are installed in banks, factories, large stores, offices, etc. to monitor theft or other possible accidents or to identify major intersections and traffic conditions.

The surveillance system installed and used in this way is a monitor that outputs the image taken from the camera and a separate VCR that can record and play back the recorded image, or more recently, a hard disk of a computer or a separate hard disk. Will record using

In the case of the surveillance system, the surveillance camera continues to operate regardless of whether a motion occurs in the surveillance region, and the continuous operation of the surveillance camera is continuously recorded and stored in a separate VCR or hard disk.

Therefore, in the case of a VCR or a hard disk with limited recording and storage capacity, an inefficient case may occur in which the recording cannot be performed due to the limited recording amount or storage amount when actual movement occurs due to the continuous monitoring operation. There is an uneconomical problem that requires a large amount of recording tapes and hard disks.

In addition, in the case of the surveillance system, there is a problem that the lifespan of the system is shortened by the degradation of the surveillance and recording device such as the imaging device of the surveillance camera and the head of the VCR according to the continuous surveillance operation.

Recently, the surveillance system has a sensing means for detecting the movement of the surrounding environment around the surveillance camera is installed to reduce the consumption of the recording tape and hard disk by operating the surveillance camera to shoot and record when the movement occurs by the sensing means. One has been developed to help.

However, in the surveillance system used as described above, it also causes the deterioration of the device due to the continuous surveillance operation, and in the case of the VCR, which is a recording device for recording the image taken from the surveillance camera, it is usually used in general household Since a VCR that can be dedicated to a surveillance system is used instead of a VCR to be used, there is a problem that a VCR that can be used in a general household cannot be replaced in the event of a degradation as described above. All of the devices are connected by wire, which causes troublesome installation.

Therefore, the object of the present invention is to remotely operate the home VCR by the microcomputer when the motion is detected in the environment in which the surveillance camera is installed, but to record and stop only for a predetermined time, to prevent unnecessary recording to replace the VCR tape It is intended to keep the monitoring state for a long time by extending the.

In addition, another object of the present invention is to store the remote control signal of the home VCR when the movement of the surrounding environment occurs so that the recording of the VCR by the remote control signal of the stored VCR, without modifying or changing the home VCR Since it can be used as a monitoring VCR, there is no need to provide a separate monitoring VCR, to provide convenience and economy in use.

In order to achieve the above object, the present invention provides a power supply unit for supplying operating power to the entire system; An input unit for inputting a remote control signal corresponding to a recording time and a VCR operation according to a user's use selection; A detection unit for detecting whether a situation requiring surveillance recording in the surrounding environment has occurred; Limiting unit for limiting the monitoring operation according to any particular time zone or the surrounding monitoring environment desired by the user; A microcomputer for recording a signal input from the input unit and outputting a stop operation signal by a predetermined program; A light emitting unit converting the electrical signal output from the microcomputer into an infrared signal and outputting the infrared signal; A display unit which displays an operating state of the micom and an operating state of the device; Surveillance camera unit for receiving the operating power from the power supply unit for photographing the surrounding environment; And a video cassette recorder which records and outputs a video signal photographed from the surveillance camera while receiving and driving a signal output from the light emitting unit.

Therefore, according to the present invention, when the motion state of the surrounding environment is detected by recording the video signal recorded by applying the operation signal to the surveillance camera operation and the VCR by the control signal of the microcomputer, the input is recorded only during the arbitrarily set time, unnecessary recording By limiting the recording time of the VCR, the recording time of the VCR is not only reduced, thus reducing unnecessary waste caused by frequent replacement of the VCR tape, and also reducing the operating time of the surveillance camera and the VCR, thereby extending the life of the surveillance camera and the VCR.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a detailed block diagram of a control device of a video cassette recorder for recording a surveillance camera of the present invention, and FIG. 2 is a flowchart of a control device of a video cassette recorder for recording a surveillance camera according to the present invention, which supplies operating power to the entire system. A power supply 101; An input unit 102 for inputting a remote control signal for recording time and power, recording, and stopping operation according to a surrounding monitoring situation; A detection unit 103 for detecting whether a situation requiring surveillance recording in a surrounding environment occurs; Limiting unit 104 for limiting the monitoring operation and stop arbitrarily in accordance with any particular time zone or the state of the surrounding monitoring environment desired by the user; A microcomputer 105 for storing a signal input from the input unit 102 and outputting power, recording, and stop signals during a recording operation by a preset program; A light emitting unit 106 for converting the signal output from the microcomputer 105 into an infrared signal and outputting the infrared signal; A display unit 107 for displaying an operation state of the microcomputer 105 and an operation state of the device; Surveillance camera unit 108 for receiving the operating power from the power source 101 to photograph the surrounding environment; A light receiving unit 201 receiving an infrared signal of power, recording, and stop output from the light emitting unit 107; The VCR 200 is configured to record an image signal photographed from the surveillance camera 105 by the signal received by the light receiver 201.

The input unit 102 includes a semi-fixed resistor or switch for setting a recording time; The light receiving unit receives an infrared remote control signal of the VCR 200.

The detection unit 103 is a sensor installed around the camera installation site and detects a movement state of the surrounding environment, and includes an infrared motion sensor or an ultrasonic sensor, and a door switch.

The limiting unit 104 is configured as a photosensitive switch or a timer that prevents unnecessary recording by blocking the input of the signal to the microcomputer by limiting the monitoring time according to a specific time zone or the surrounding monitoring environment.

The microcomputer 105 mounts an EEPROM internally or externally, and stores power, recording, and stop signals, which are randomly set programs and remote control signals of the VCR 200, to be repeatedly written for future VCR operations. In addition, when a situation occurrence signal required for recording is input from the sensing unit, a command signal is sent to the power supply unit to supply power to the surveillance camera unit, and the remote control signals stored in the EEPROM are set in accordance with the setting contents of the program or the input setting unit. After the VCR 200 is turned on at a time interval and the VCR 200 is turned on to perform recording, the VCR 200 is turned off to be in a standby state or the power of the surveillance camera is cut off to maintain the standby state.

The display unit 106 displays an operation setting, a power supply, a recording, a stop, and a standby state, which are operating states of the microcomputer 105.

The light emitting unit 107 is composed of an infrared element for outputting a remote control signal of a VCR controlled and output by a program stored in the microcomputer 105 as a predetermined infrared signal.

The surveillance camera unit 108 is configured to photograph the surrounding environment while driving by receiving power from the power supply unit 101, and record the photographed signal directly on the VCR 200.

According to the present invention configured as described above, first, a predetermined driving voltage is generated from a power supply voltage input through the power supply unit 101 to supply driving power to the microcomputer 105, the monitoring camera unit 108, and each unit.

Subsequently, the user inputs an infrared remote control signal of the remote controller for powering, recording, and stopping the VCR 200 through a light receiving unit provided in the input unit 102, and sets a recording time by operating a semi-fixed resistor or a switch. In addition, the user sets a specific time zone or a necessary monitoring time for which no recording is necessary according to the surrounding environment and monitoring conditions by using a timer or a dimming switch of the limiting unit 104, so that the monitoring operation is not performed during this set time. The time limit or the operating time zone is stored in the EEPROM via the microcomputer 105 (step 300).

At this time, the microcomputer 105 displays the set state of the monitoring mode set by the input unit 102 through the display unit 106.

When the mode for the monitoring operation is completed in the microcomputer 105 as described above, the microcomputer 105 determines whether the monitoring time set by the input unit 102 has been reached by a predetermined program (step 301). At this time, if the monitoring time has not reached, the microcomputer 105 maintains the standby state.

On the other hand, when the monitoring time is reached, the microcomputer 105 detects a situation requiring recording of the surrounding environment through the infrared motion sensor or the ultrasonic sensor of the detector 103 and the door switch (step 302). At this time, if the monitoring situation for the surrounding environment is not detected by the sensing unit 103, the standby state is maintained.

However, when the monitoring situation is detected through the detection unit 103, the microcomputer 106 supplies the driving power to the surveillance camera unit 108 through the power supply unit 101 to cause the surveillance camera unit 108 to operate. In addition to photographing the current movement of the surrounding environment, the microcomputer 106 controls the light emitting unit 107 to control power and recording, which is a remote control signal of the VCR 200 set by the input unit 102 and stored in the EEPROM. The signal is converted into an infrared signal and output to the light receiving unit 201 of the VCR 200. The VCR 200 turns on the VCR 200 by power and recording signals received through the light receiving unit 201. Then, recording is performed so that the video signal captured by the surveillance camera unit 105 is directly recorded on the VCR 200 (steps 303 and 304).

At this time, the time recorded in the VCR 200 is recorded by the semi-fixed resistor or the switch of the input unit 102 for a predetermined time, and then it is determined whether the set recording time is completed (step 305).

Accordingly, if the recording time is not completed, the recording is continued. On the other hand, if the recording time is completed, the microcomputer 105 emits light by the remote control signal of the remote controller set by the input unit 102. Outputs a stop signal and a power signal to the light receiving unit 201 of the VCR 200 to maintain the recording and stopping of the VCR 200, and to control the power supply 101 to the surveillance camera 108. The power is cut off to keep the surveillance camera 108 in the standby state (step 306).

In the state of maintaining the standby state as described above, the microcomputer 105 determines whether the preset monitoring time is completed by the input unit 102 (step 307). In step 105, the sensing unit 103 detects a monitoring situation and performs recording several times during the set recording time. On the other hand, when the monitoring time is completed, the microcomputer 105 detects the detecting unit 103. Ignoring the change in the surveillance situation from the to maintain the VCR 200 and the surveillance camera 108 in the standby state.

As described above, the present invention controls the surveillance camera and the VCR by the infrared remote control signal which is set when the surveillance situation occurs while the surveillance time and the recording time of the monitored situation are set according to the surrounding surveillance environment. By recording during the set monitoring time and recording time, unnecessary monitoring operation is restricted, which prolongs the recording usage time of the VCR tape, thereby extending the tape replacement time, and monitoring by the monitoring time and recording time limit. This prevents deterioration of cameras and VCRs, thus enabling the longevity of surveillance systems.

In addition, the present invention can be recorded by using the VCR used in the general home as the recording operation of the VCR by the infrared remote control signal of the remote controller that is input to the EEPROM provided in the microcomputer during the monitoring operation can be recorded as it is, It will provide the effect to prevent the economic loss of VCR provision.
