Active security entrance guard control method and control system

Abstract

The invention relates to the field of security and particularly relates to an active security entrance guard control method and an active security entrance guard control system. The control system comprises a detection module, an alarming device and a relay connected with the detection module and the alarming device, wherein the detection module comprises a radar and a judgment device connected with the radar and is connected with a power supply; the radar is used for detecting an outdoor condition within a detection range in real time; the judgment device can instantly perform logic judgment if someone or something stands in the detection range; the judgment device can send an electric signal to the input end of the relay if a judgment result is not gate; the relay is used for closing and switching on a circuit to supply power to the alarming device after receiving the electric signal sent by the detection module; the alarming device is used for sounding an alarm after a power supply is switched on. The system can actively detect the outdoor condition, make a judgment on a person having some attempts or a functional object, actively sound the alarm to inform persons in a room and implement monitoring on the outdoor environment, so that the security level is increased; the alarming accuracy is high; the control system is difficult to crack and is low in cost.

Description

technical field [0001] The invention relates to the security field, in particular to an active security access control method and control system. Background technique [0002] When it comes to security, most people's first impression is the cameras, alarms, anti-theft devices and other similar equipment seen in some public places. It has been widely used in public commercial space security system, including video surveillance, burglar alarm, access control intercom and other subsystems. But it is also difficult for people to combine this high-tech lockset with the lives of ordinary people. Now, with the continuous improvement of people's security awareness, the trend of household security has gradually emerged. Not only will it continue to develop in commercial use in China, but it will also have a broader prospect in civilian use. Therefore, there is a great market space for the development of active security access control system. [0003] However, the existing security...

Problems solved by technology

[0003] However, the existing security technologies such as sensors, detectors, radars, cameras, alarm devices, etc., are all configured at the level of passive security. Outdoor visitors need to trigger the notification sound through the doorbell, and indoors only Passively inform the outdoor situation, unable to make active judgments, and will only send out an alarm after abnormal actions occur, and cannot guard against people or functional objects with certain intentions

And using simple sensor detection and alarm, the rate of false alarm is high

And the required cost of existing anti-access control system in the prior art is generally on the high side
