Non-identification safety sensing system and method

The technical field of the present invention relates to a non-identification safety detection system and method, and in particular, by using a ToF (time of flight) sensor detection method to protect personal privacy by non-identification and to detect safety in a dangerous state or an emergency state. It relates to a non-identifying safety detection system and method.

In a system for detecting safety in a dangerous or emergency state, a surveillance camera is widely used. The surveillance camera is installed on a normal pole and takes pictures in real time. It performs the function of recording the crime video so that it can be helpful by checking the recorded video or used to find the criminal later.

These surveillance cameras generally use closed circuit television (CCTV) cameras, but high-performance IP cameras are also used. In particular, in a reality where safety blind spots are increasing due to increasing female drivers and large parking lots in buildings, parking lots in apartments and buildings are being pointed out as new crime scenes. Accordingly, emergency bells and CCTV cameras are installed in safety blind spots to prevent crime in parking lots of apartments and building buildings. Each connected to the operation server of the management room or disaster prevention room through, and the operation server provided in the management room or disaster prevention room also consists of a large rack having a signal distributor, and is configured in the form of having a video storage device and a monitoring device.

This system has a separate operating server with a signal distributor, and emergency bells, speakers, and CCTV cameras installed on site are installed through separate piping and wiring. The process is complicated, and there is a disadvantage in that a lot of cost is required along with an increase in construction time accordingly.

Korean Registered Patent No. 10-1832446 (registered on February 20, 2018) discloses an emergency bell-CCTV integrated system that implements a two-way call function in an emergency bell through a single network, which is installed in a safety blind spot in a parking lot in a building. And, in case of an emergency, it is driven according to the execution of the user's manipulation to generate and transmit a preset emergency bell signal, and an emergency bell device having a two-way call function; A camera unit installed in a safety blind spot of a parking lot in a building, monitoring and photographing the surrounding area, and automatically connected to receive an emergency bell signal generated by an emergency bell device; A camera unit connected to the emergency bell device and a network connection unit connected to a single network; And connected to the network connection unit, detects the emergency bell signal generated by the emergency bell device, controls the emergency warning in response to the detected emergency bell signal, and at the same time performs a two-way call with the emergency bell device requesting an emergency call Including the NVR (Network Video Recorder) management unit provided in the management room or disaster prevention room, but the emergency bell device uses the CCTV line of the camera unit without the need for separate piping or wiring. It is fixedly installed in the shape of an enclosure in the safety blind spot, and the camera unit consists of an IP camera with an audio board connected to the emergency bell device, but the emergency bell device and IP camera are 1: 1, or the emergency bell device and IP It is characterized in that the camera is implemented as an event monitoring device in a 1:N combination. According to the disclosed technology, an emergency bell device equipped with a two-way call function is connected to the audio board of the camera unit to receive an emergency bell signal, and the camera unit and the NVR management unit are connected to a single network through a network connection unit, so that an emergency situation Two-way communication is possible along with a request for help through an emergency call in the event of an emergency. Accidents are prevented in advance through prompt and accurate response to risk factors in the safety blind spot that occur frequently, thereby relieving user anxiety and living a safe life. Space and crime can be prevented in advance.

Korean Patent Publication No. 10-2014-0088004 (published on July 9, 2014) detects changes in physical values such as shock even when there is no separate manipulation of children and dementia patients in dangerous situations such as crimes or acute diseases, Since it determines whether or not there is a dangerous situation, it is possible to more quickly and efficiently communicate the dangerous situation to the guardian or public institution, and this dangerous situation is transmitted to the guardian through the portable terminal of the guardian or the terminal of the public institution so that an effective response can be made. If you use the application installed on these guardian terminals, two-way communication is possible to inform a person in danger of appropriate countermeasures, or to continuously communicate about dangerous situations in an automatic notification method to help solve problems. A two-way safety control service system based on the same and a control service method using the same are disclosed. According to the disclosed technology, it is connected to a wired/wireless communication network, has a sensor unit that generates owner status information according to the movement of the owner, determines the level of risk based on the owner status information, and automatically sends an emergency signal set according to the level of risk to the wired/wireless communication network. A portable device that transmits to the outside through; A control server for receiving and storing an emergency signal through a wired/wireless communication network and transmitting notification information set according to the emergency signal to the outside through a wired/wireless communication network; and a guardian terminal for receiving and outputting notification information through a wired/wireless communication network and transmitting a remote control signal to a portable device through a control server.

In the conventional technology as described above, in the case of the CCTV method, the administrator judges whether or not there is an abnormality through several monitor screens in the central control room, or the recording is played back and tracked after a crime or accident, and the safety detection is measured. In the case of general building management, hospital facilities, production sites, and industrial facilities such as farms and warehouse facilities, it is a very important management point. In particular, in the case of motion detection data, the management level Unlike other CCTV installation areas, it is recognized as important in blind spots where crimes or accidents often occur. However, because CCTV is a recording method, it is difficult to manage safety in blind spots in buildings such as elderly care/medical institutions, institutions for the disabled, toilets, and changing rooms. There is a downside to being in an impossible situation.

In the conventional technology as described above, in the case of intelligent CCTVs currently on the market, information on objects interacting with human motions, postures, and positions is grasped in real time, such as wandering, intrusion, fighting, arson, falling, abandonment, etc. can detect abnormal behavior, but as a video storage device, there is no choice but to install and operate it only in public places used by an unspecified number of people in accordance with Article 25, Paragraph 1 of the Personal Information Protection Act, eliminating blind spots, which are prohibited areas for filming. There was a limit to In addition, in the conventional technology as described above, in order to detect states such as falling, fainting, and neglect for a specific place, each separate installation system must be built and assembled, so each necessary detection device and communication system must be installed separately. As a result, not only the management system becomes complicated, but also has the disadvantage of requiring a large installation space and increasing maintenance costs accordingly.
