Audible and visual alarm with classified voices for mines

Abstract

The invention provides an audible and visual alarm with classified voices for mines. The alarm comprises a base, a lamp cover, a supporting member, a suspension ring, a wire outlet, a cover plate and a circuit device. The circuit device comprises a main circuit board, a horn and five light-emitting diode (LED) circuit boards. The horn and the five LED circuit boards are all electrically connected with the main circuit board. The circuit device performs flashing alarm and voice alarm simultaneously according to received alarm trigger signals. The circuit device is fixedly mounted on the base through the supporting member, and the lamp cover is fixedly connected with the base in a sealing mode. The suspension ring and the wire outlet are both mounted on the base. The cover plate is magnetically attracted on a base board of the base. Each of the LED circuit boards is provided with 4 to 12 high-brightness red LEDs and 4 to 12 of high-brightness green LEDs. According to the audible and visual alarm with classified voices for mines, the shatter and shock resistance is good, and the alarm light is 360-degree visible; the voice alarm voice quality is good, no noise exists, and alarm contents are convenient to edit; and the alarm trigger signals can be combined and arranged in a classified mode, and the voice alarm can be controlled remotely.

Description

technical field [0001] The invention relates to an alarm, in particular to an intrinsically safe voice, sound and light alarm for mines. Background technique [0002] The underground environment of coal mines is harsh. In order to ensure the personal safety of underground operators, a large number of sensors are installed to detect various environmental parameters such as gas, carbon monoxide, carbon dioxide, oxygen, temperature, etc. sensors etc. Various types of sensors for these safety environment monitoring and working condition parameter monitoring have different forms. Many sensors have sound and light alarm functions, but most of them are "beep" buzzer alarms and / or flashing indicator lights. The surrounding area of ​​the sensor plays a certain warning role, and the operator far away from the sensor cannot perceive it, and the early warning effect is not good. With the continuous improvement of coal mine safety production awareness and the continuous strengthening o...

AI Technical Summary

Problems solved by technology

[0003] At present, the sound and light alarms on the market are designed based on the recording and playback voice chip or the voice synthesis chip. Recording, often noisy, poor playback effect

Products using speech synthesis chips have no noise, but the sound quality is blunt, and the clarity is not high when encountering long sentences

Moreover, the voice alarm content of this type of alarm is single, and the centralized alarm of multi-point alarm sources cannot be realized.

Light alarm The ground generally adopts a mechanical rotating structure flashing alarm, and the underground design generally adopts the front and rear round LED lights, or the form of 2 LED lamp posts, the visual surface is narrow, and the light alarm effect is general
