Embodiment Construction

[0024] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0025] A kind of low power consumption wireless smoke alarm device of this embodiment, its working principle is as follows figure 1 shown. The smoke alarm sends the data of smoke information and telemetry information to the micro-power wireless module through serial communication, encrypts and compresses it through the micro-power wireless module, and then decrypts and decompresses it through the micro-power wireless receiving module, and sends the data to the smoke sensor on the PC side Software or receiving host for analysis and display.

[0026] A low-power wireless smoke alarm device of this embodiment, its structural block diagram is as follows figure 2 As shown, it includes a micro-control unit, a data acquisition module, a power supply module, a switching value control circu...

Abstract

The present invention discloses a low-power-consumption wireless smoke alarm device and belongs to the sensing, detection and safety alarm technical field. The low-power-consumption wireless smoke alarm device comprises a micro control unit, a smoke sensor, a data acquisition module, an alarm circuit, a switching quantity control circuit, a micro power wireless module and a power source module; the micro control unit is connected with the data acquisition module, the power source module, the switching quantity control circuit, the alarm circuit and the micro power wireless module; and the dataacquisition module is connected with the smoke sensor. According to the low-power-consumption wireless smoke alarm device, the micro control unit which adopts a Cortex M3 architecture is used to perform control, and therefore, a low power consumption mode and an A / D conversion function can be realized; an ion type MQ-2 smoke sensor module is adopted as the smoke sensor, and therefore, high sensitivity is realized, and early warning can be realized more quickly; and the wireless analysis and warning of the device are realized through the micro power wireless module, and therefore, data are more sensitive than data obtained through a manual mode, and reaction time is decreased, and the debugging efficiency of the warning is improved, and safety is enhanced.

Description

technical field [0001] The invention relates to the technical field of sensing and detection safety alarms, in particular to a low-power wireless smoke alarm device. Background technique [0002] The smoke alarm device realizes fire prevention by monitoring the concentration of smoke, and its technical indicators determine the rapidity and stability of the alarm device. [0003] Traditional smoke alarm devices are all wired data transmission, the data transmission rate is slow and unstable, the circuit is complex, and the power consumption is large. A wired smoke alarm device generally consists of a detection unit, an alarm unit, a display unit and an alarm control unit. With the development of science and technology, the number of household appliances is increasing day by day, and the wiring is becoming more and more complicated. The wired smoke alarm device may not alarm in time. If the alarm line is burned first, the smoke alarm device will be useless. Therefore, wirele...
