Power protection device for building space wireless anti-theft fire fighting communication host

Abstract

The invention discloses a power protection device for a building space wireless anti-theft fire fighting communication host. A main power detection module is connected with a main power supply and consists of a step-down circuit and a voltage detection circuit; the step-down circuit reduces the voltage of the main power supply for supplying power to a reference voltage value; the voltage detection circuit can detect the reference voltage value and output a detection signal when the reference voltage value is less than a default value; a micro-processing unit receives the detection signal output by the main power detection module, analyzes the detection signal and then is switched to a standby power supply for power supply and generate a control signal; and a mobile communication module can receive the control signal output by the micro-processing unit and transmit a mobile telephone short message to notify related personnel to know about the current power supply state so as to maintain the normal operation of the entire system.

Description

Technical field: [0001] The invention relates to a power supply protection device for a wireless anti-theft fire-fighting communication host in building space, especially a device that can switch to a backup power supply when the normal power supply of the anti-theft fire-fighting host for security is abnormal, and notify relevant personnel with a mobile phone text message A power protection device that generates a warning action at the same time. Background technique: [0002] With the complexity of the social environment, various public security problems emerge in endlessly, among which theft is the most common and serious problem for ordinary people's safety and property loss. Therefore, anti-theft hosts with various detection functions are widely used in families and factories. Or in other spaces to be protected, the common small anti-theft host can cooperate with various detection components (such as: magnetic reed switch, body temperature and ultrasonic sensor) to sens...

Problems solved by technology

[0003] Yet above-mentioned simple and small-sized anti-theft host computer is in actual application, except that there are many inapplicable occasions or lack (as: in the detached house that does not have adjacent building, the frightening effect that this alarm sound produces is limited; Or management The on-duty personnel in the room temporarily leave the sleeping position or delay the response due to negligence), and because the anti-theft host and its related components all use a single power supply (and general commercial power) power supply system, unless an uninterruptible power supply is additionally configured device (UPS) to provide a backup power supply when the external power supply (mains) is abnormal (power outage or man-made damage), otherwise, the anti-theft system as a whole will be difficult to maintain normal operation due to lack of power supply, let alone play its due role Anti-theft or security features, this is a serious lack of applications
