Entrance guard device

Abstract

The invention discloses an entrance guard device, which comprises an information reading module, a temperature and humidity sensing module, a processing module and a power supply control module, wherein the information reading module is used for reading identity information of an incomer, and integrating the identity information and the entering time and place information of the incomer to form entrance allowing information; the temperature and humidity sensing module is used for sensing the temperature and humidity information of located environment of the entrance guard device; the processing module is used for receiving the entrance allowing information sent by the information reading module, confirming the entrance allowing condition of the incomer so as to control the off-on state of an electric lock module of the entrance guard device, and receiving the temperature and humidity information in real time; when the temperature and humidity information is greater than the preset threshold, the alarm of the entrance guard device is triggered; the power supply control module is used for controlling the power supply module of the entrance guard device to output various different voltages so as to respectively supply electricity to modules with different voltage requirements. By using the entrance guard device, the problem of the environment temperature and humidity influence can be solved; meanwhile, when the voltage is too high, the high-pressure protection can be given; when the power supply generates reverse power supply, the reverse power supply protection can be protected; the system can still normally operate and work.

Description

technical field [0001] The invention relates to the field of security monitoring, in particular to an access control device. Background technique [0002] The currently used access control system does not yet have the conditions to monitor its own temperature and humidity. If the operating environment of the equipment is relatively harsh, the performance of the equipment will often be affected, resulting in some unknown failures in the system. Moreover, when the power supply is reversed or unstable, the existing access controllers cannot provide sufficient protection, which can easily cause system components to be damaged. And because the current access control system products do not have the high voltage protection function. Assume that during the installation or maintenance of the card reader of the access control system, the technician’s operation makes the interface of the card reader mistakenly touch other high-voltage contacts or other mistakes lead to wrong wiring a...
