Problems solved by technology

[0002] The action of the existing fire alarm is generally to make a sound to remind the user whether there are parameters exceeding the standard in the environment, or to start a corresponding device such as an exhaust fan to replace the toxic and explosive gas in the field environment; but there is no such thing as yet. It can trigger the method or device of the protection alarm itself;

Embodiment Construction

[0011] The structure of alarm device of the present invention

[0012] figure 1 The schematic structure 100 of the alarm of the present invention is shown, wherein the permanent magnetic adsorption base 102 is fixed on the wall 101 by mechanical fixing methods such as screws and slots or adhesion, and the alarm is connected to the permanent magnet through the metal part 103 of the back shell. The magnetic force generated by the adsorption base 102 is indirectly fixed on the wall 101 by the friction force generated further; an alarm circuit board 110 is installed in the alarm, and a microprocessor 111 and a temperature sensor are integrated on the alarm circuit board 110 112; wherein the microprocessor 111 coordinates the temperature sensor 112 to collect the temperature. When the fire spreads, because the temperature at the top of the room rises to a higher dangerous temperature faster, this temperature may cause the alarm to fail to work normally; The temperature sensor 112 ...

Abstract

According to the feature that fire spreads along a ceiling, a device and a method of prolonging the working efficiency of an alarm at a fire site are provided. When a sensor detects temperature at a higher position in a room exceeds the standard and working of the sensor is improper, the sensor generates a repulsive force through an electromagnet back shell part, the sensor then falls to a position with lower temperature, and thus, the working efficiency of the sensor at the fire site can be prolonged.

Description

technical field [0001] The present invention relates to the field of automatic control, in particular to a device and method for detecting an action. When it is detected that the position of the device is too high and it is not suitable for the normal operation of the device, the control device falls off from a high place and falls to a place with a relatively low temperature. The bottom plate, thereby prolonging the working life of the device at the fire scene. Background technique [0002] The action of the existing fire alarm is generally to make a sound to remind the user whether there are parameters exceeding the standard in the environment, or to start a corresponding device such as an exhaust fan to replace the toxic and explosive gas in the field environment; but there is no such thing as yet. It can trigger the method or device of the protection alarm itself; Contents of the invention [0003] The invention includes a permanent magnetic adsorption base for absorb...
