Problems solved by technology

[0003] However, the existing technology has almost no anti-sabotage measures for the alarm itself. If criminals attempt to destroy the alarm device first and then perform other illegal acts, the original alarm device will not work, and relevant personnel cannot be notified to take timely measures. so as not to achieve the purpose of warning

Abstract

The invention discloses an alarm device capable of preventing man-made sabotage, which includes an alarm body and a controller, an alarm cover is arranged outside the alarm body, the alarm cover is connected with a controller, and the controller It includes an input rectifying circuit, a monostable trigger circuit, a sound simulation circuit and a power amplifier circuit connected in sequence; the material of the alarm cover is a touch metal sheet. In the present invention, an alarm cover and a controller connected with the alarm cover are provided for the alarm. Once damage or disassembly occurs, an alarm will be issued in advance to prevent damage or disassembly of the alarm itself.

Description

technical field [0001] The invention relates to an alarm device, in particular to an alarm device capable of preventing man-made damage. Background technique [0002] An alarm is a product that reminds or warns us that we should take certain actions in the form of sound, light, air pressure, etc. in order to prevent or prevent the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. , with the advancement of science and technology, mechanical alarms are more and more replaced by advanced electronic alarms, which are often used in the fields of system failure, safety precautions, transportation, medical rescue, emergency relief, induction detection, etc., and social production Inseparable, such as door magnetic sensors and gas sensor alarms and so on. Household thieves intruded mainly through doors and windows, and the proportion of door burglars was greater than that of window burglars. A door magnetic sensor is installed on the door o...
