Description

Technical Field

[0001] The present application relates to the technical field of alarms, and in particular to an acoustic and optical alarm with a wireless communication function. Background Art

[0002] In related technologies, in the equipment of explosion-proof detectors, most are connected to alarm control equipment in a wired manner, which results in complex engineering construction and high costs. Using a wireless method for communication is simpler, more convenient, and has lower costs in engineering construction. However, when an explosion-proof detector realizes wireless communication, since its housing structure is made of metal, which plays a shielding role for communication, it is necessary to redesigned the housing structure to lead out the antenna; this will cause damage or modification to the housing, or redesigned the structure; on the one hand, it is rather troublesome, and on the other hand, it increases potential safety hazards.

The single-chip microcomputer receives the wireless signals sent by external wireless devices, converts them into a wired method to communicate with the buzzer, and the single-chip microcomputer controls a light-emitting indicator of a certain color to conduct according to the pre-burned program. For example, when alarming, the red light-emitting indicator conducts and flashes, and controls the buzzer to sound; the single-chip microcomputer converts the alarm information of the buzzer obtained through the wired method into wireless communication and sends it out; since it communicates with external wireless communication devices through wireless communication, the number of connection interfaces is reduced, thus reducing potential safety hazards.

One end of the ventilation hole communicates with the outside, and the other end communicates with the cavity. The axis of the ventilation hole is arranged at an acute angle to the axis of the transparent plastic cover.

[0015] By adopting the above technical solution, the components inside the transparent plastic cover can be cooled, and since the ventilation holes are inclined, the entry of dust and the like into the transparent plastic cover can also be reduced.

[0016] Optionally, the sound and light alarm further includes:

[0017] A bracket, fixedly connected to the base;

[0018] A rotating rod, rotatably connected to the bracket;

[0023] A threaded sleeve, fixedly connected to the bracket, and the rotating rod coaxially passes through the threaded sleeve;
