Description

An intrusion perceptive system from the outside of building}

The present invention relates to a system for detecting outside intrusion of a building, and more particularly, when an external intruder is detected in a room formed in an apartment, an officetel, or a building, a video camera is operated to predetermine indoor video and audio data. It can be recorded on a computer installed at a location, and the recorded video and audio signals can be reproduced with clear image quality at any time, thereby making it possible to identify the intruder's identity and accurately identify the site in the event of a theft accident by an external intruder, which is very useful for the arrest of an intruder. The present invention relates to an external intrusion detection system for buildings.

In general, apartments that are single-family or multi-family homes are equipped with a home automation system that includes security functions, gas leak detection, and fire detection for each household to automatically connect to the guard or police station according to each detection status. .

In particular, in case of the security function, when the external intruder is detected, the alarm sound is generated and the intrusion signal is automatically transmitted to the guard room or the police station. As needed, the security function in the home automation system has not only the criminal's arrest but the function of preventing the invasion by notifying the intruder to the outside.

In addition, an officetel or an office in a building has a security system that provides services to a separate security specialist. However, when an external intrusion is detected, an alarm signal is generated and an intrusion signal is automatically transmitted to the security firm. When security guards are dispatched from the service company, the minimum time is required, so the arrest rate of criminals is very low, and thus only serves to prevent outside intrusion.

Therefore, in the case of forming a security system by selecting a security function of the home automation system or a separate security service provider as described above, if the valuable property is already stolen by an external intruder, the identity of the intruder is confirmed unless there is a witness. It is difficult to obtain evidence, so the possibility of arrest is virtually very slim, and there is a problem that the reliability is lowered.

In addition, CCTV is installed on the outside of a apartment or a building, parking lot, etc., and the video surveillance system records and plays the video and audio signals received through the CCTV. It requires a lot of tapes to store the data for a certain period of time, so excessive operating costs are required. To reduce such operating costs, it is not possible to obtain clear picture quality by reusing tapes that have passed a certain period of time. Despite the fact that it is recorded, there is a problem that cannot be identified.

The present invention is to install a human body sensor and a video camera at a predetermined position in the room formed in the building, such as apartments, officetels, buildings to solve the above problems, and when the external intruder is detected to operate the video camera automatically The video and audio signals of the indoors, which are shot by the video camera, are converted into digital signals and stored in a recording medium of a computer installed at a predetermined place for a certain period of time. As it is stored for a certain period of time, video and audio signals recorded through a computer can be reproduced with clear image quality at any time, so that in the event of a theft accident by an external intruder, it is possible to identify the intruder's identity and accurately identify the site, which is very useful for arresting an intruder. In addition to maintenance and repair costs And it is possible to minimize the operating costs so that you can create a complete security system to technical problems.

The external intrusion detection system of the building of the present invention is installed at a predetermined position in the room to detect a human body of an external intruder and outputs a predetermined signal, and is installed at a predetermined position in the room to capture an image and an audio signal in the room. And a control unit for automatically receiving and outputting a video camera, and automatically turning on and off the video camera according to the presence or absence of a detection signal from the human body sensor, and outputting a video and audio signal received from the video camera. A data storage computer capable of recording and reproducing video and audio signals transmitted from the plurality of intrusion detection units and storing the recorded data primarily for a predetermined period of time, and being stored in the data storage computer for a predetermined period of time.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to FIGS. 1 to 6.

1 is a conceptual diagram of an external intrusion detection system of a building according to the present invention, each generation (office) formed in a building such as an apartment, an officetel, a building, etc. Intrusion detection units 10a to 10b for transmitting video and audio signals are provided, and the intrusion detection units 10a to 10n are gathered together to form one device array 20a to 20n.

In addition, data storage computers 30a to 30n capable of receiving, recording, storing and reproducing video and audio signals transmitted from the intrusion detecting units 10a to 10n of the device arrays 20a to 20n for a certain period of time are connected. In addition, the plurality of data storage computers 30a to 30n are connected to the server 40 for receiving the data of which the storage period is completed and storing the secondary again for a predetermined period.

That is, by detecting the external intruder from each household (office), the video and audio signals are first stored in the data storage computers 30a to 30n for a certain period of time, and then transmitted to the server 40 to be stored for a second period of time. It is possible to maximize the data retention period.

In addition, the probability that all generations connected to one data storage computer 30a can go out at the same time is difficult. Moreover, even when all generations go out at the same time, an external intruder invades all generations at the same time. When the intrusion detection unit 10a to 10n of the operation is very rare, the data storage computers 30a to 30n can use a hard disk (about 30GB) of a home personal computer generally used, and the server ( The data stored in 40 may also be automatically deleted after a certain period of time, thereby eliminating the need for a large capacity, thereby enabling the installation of the system of the present invention at low cost.

Figure 2 is a block diagram of the intrusion detection unit 10a in the external intrusion detection system of a building according to the present invention, is installed at a predetermined position that is easy to invade the entrance of the room or the outside and detects a human body to detect a predetermined signal. A human body sensor 12a (12b) for output, a video camera (11a) (11b) is installed at a predetermined position in the room to shoot and receive the video and audio signals of the room and the human body sensor 12a The video cameras 11a and 11b are automatically turned on and off in accordance with the presence or absence of a detection signal from 12b, and an interrupt signal is transmitted to the data storage computer 30a to be received from the video cameras 11a and 11b. And a control unit 13 for transmitting the video and audio signals to the data storage computers 30a to 30n.

3 is a block diagram of the control unit 13 in the external intrusion detection system of a building according to the present invention, which converts the video and audio signals output from the video cameras 11a and 11b into digital signals and outputs them. D converter 21, a buffer 22 that buffers the output data of the A / D converter 21 and transmits the data to the data storage computers 30a to 30n, and the outputs of the human body sensors 12a and 12b. Depending on whether or not the video camera (11a) (11b) is automatically turned on and off, the microprocessor 24 for controlling the entire system by driving the buffer 22, and the data is exchanged with the microprocessor 24 Rom 26 in which a unique number for each generation is stored and a program for controlling the system is embedded, and a power button 23a connected to one side of the microprocessor 24 to supply power to the system, for driving the system. Detect button 23b at system stop Is composed of a release button (23c) is set to the operating unit 23 and the output side of the microprocessor 24, the lamp corresponding to the operation of each button (23a ~ 23c) of the operation unit 23 And an MPU drive 25 including an oscillation circuit for driving the microprocessor 24 and the display unit 27 that lights up to display an operation state.

4 is an operation flowchart of the sensing unit of the control unit 13 in the external intrusion detection system of the building according to the present invention, Figure 5 is the operation of the data storage computer 10a in the external intrusion detection system of the building according to the present invention. It is a flow chart.

3 and 4, the operation process of the external intrusion detection system of the building will be described. First, when the power button 23a of the operation unit 23 shown in FIG. 3 is operated, power is supplied to the microprocessor 24. After initializing the system (step 101), the power lamp 27a of the display unit 27 is turned on to indicate that it is in the standby state.

In this state, when the monitoring button 27b of the operation unit 23 is operated to switch to the monitoring system immediately before going out, the microprocessor 24 recognizes this (step 102) to detect the detection lamp 27b of the display unit 27. At the same time, the signal output from the human body detection sensors 12a and 12b installed at the entrance or invasion is read at regular intervals (step 103).

At this time, when an external intruder is generated, the human body is detected by the human body sensors 12a and 12b to transmit a human body detection signal to the microprocessor 24 of the control unit 13, and the microprocessor 24 detects the human body. When it is determined that the signal is received (step 104), the video cameras 11a and 11b are operated (step 105) and the buffer 22 is enabled to transmit an interrupt signal to the data storage computer 30a. .

Accordingly, the video signal and the audio signal, which are analog signals output from the video cameras 11a and 11b, are converted to digital data as they are transmitted to the A / D converter 21, and the data storage computer 30a is transferred through the buffer 22. The microprocessor 24 reads the unique number designated for each generation stored in the ROM 26 and transmits the data to the data storage computer 30a through the buffer 22 (step 106). do.

That is, the data storage computer 30a simultaneously receives the unique number designated for each generation and the video and audio data transmitted from the video cameras 11a and 11b.

On the other hand, the microprocessor 24 continuously reads the output signal from the human body sensors 12a and 12b at regular intervals (step 107), and if the human body signal is continuously received in this process, It maintains the state and receives data output from the video cameras 11a and 11b. If the intruder's body is not detected, the data is received by transmitting an interrupt release signal to the data storage computer 30a (step 108). At the same time, the video cameras 11a and 11b are stopped and the standby state is switched (step 110).

FIG. 5 is a flowchart illustrating the operation of the data storage computer 30 in the external intrusion detection system of a building according to the present invention, and it is determined that an interrupt signal is applied from the microprocessor 24 of the intrusion detection unit 10a (step 202). When the unique number received through the buffer 22 is analyzed and stored in the memory, the video and audio signals converted into digital signals are recorded on the hard disk (step 204). In contrast, when the interrupt release signal is received ( Step 206) recording of the signal output from the buffer 22 is stopped (step 206).

In addition, the data storage computer 30a checks the storage time of the data recorded on the hard disk and transmits the stored data to the server 40 when the predetermined time (about 3 days) has elapsed (step 207). At the same time, the information recorded on the hard disk is deleted (step 208) to secure a space for recording the received information at all times.

On the other hand, the server 40 that receives data from the plurality of data storage computers (30a ~ 30n) is a program that stores the data for a certain period of time (about 3 days) and automatically deletes after a certain period of time is built in approximately The information is kept for six days.

The data storage computers 30a to 30n and the server 40 are stored in the ROM 26 to be reproduced by the reproducing software and input the unique number of each generation received through the buffer 22. The video and audio data received from the installed intrusion detection units 10a to 10n are reproduced and displayed on the monitor. Since this process is pure software, detailed description is omitted.

In the present invention, as a device for outputting indoor video and audio signals, it is described as a video camera 11a (11b) for convenience. The number of installations per generation of video cameras per generation is not limited. In addition, the intrusion detection unit (10a ~ 10n) can be used more effectively when embedded in the home automation installed for each generation.

As described above, the present invention installs a human body sensor and a video camera at a predetermined position in a room formed in a building such as an apartment, an officetel, or a building, and automatically operates the video camera when an external intruder is detected. Converts video and audio signals of indoors that are captured by video cameras into digital signals and stores them in a recording medium of a computer installed in a certain place for a certain period of time, but after a certain period of time, they are transferred to a server with a large capacity of recording medium By keeping it for a long time, it is possible to play back the recorded video and audio signal with clear image quality at any time, so it is very useful for the detection of intruder by identifying the intruder's identity and accurately identifying the site in case of theft accident by an external intruder. In addition, operating costs such as maintenance and repair costs I can not digest is that you can create a complete security system.
