Device suitable for limited space environment gas detection and communication

Abstract

The invention dislcoses a device suitable for limited space environment gas detection and communication. A detection unit (A), a control unit (B) and a communication unit (C) are connected in sequence; the detection unit (A) is formed by connecting a camera module (1) and a gas sensor module (2) in parallel; in the control unit (B), an SPI communication module (3), an AD conversion module (4) anda 485 communication module (5) are connected in parallel and then are connected with an input end of a microprocessor circuit (6) in series, and a UART-to-AP interface circuit (7) and a UART-to-GPRS interface circuit (8) are connected in parallel and then are connected with an output end of the microprocessor circuit (6) in series; the communication unit (C) is formed by connecting an AP module (9) and a GPRS module (10) in parallel; a power supply unit (D) consists of multiple isolated power circuits. The device has the advantages of simple structure, simple maintenance, low cost, universality, versatility and data communication function; two wireless communication modes are provided, short-distance and long-distance wireless data transmission can be realized, and a user can select for use according to specific needs.

Description

Technical field [0001] The invention belongs to the field of electronic detection technology, and specifically relates to a device for detecting and communicating with the safety of gas in a limited space environment. It not only realizes the detection of the environment in the limited space, but also transmits data signals to the control through wireless communication. Display terminal. Background technique [0002] For a long time, people’s safety awareness of limited space operations has been relatively weak, leading to frequent occurrence of safety accidents in limited space operations. For this reason, the State Administration of Work Safety has strengthened the safety management of limited space operations to ensure the safety and health of personnel entering the limited space. To prevent and control the occurrence of production safety accidents such as poisoning, suffocation, fire, explosion, etc., a procedural system of "ventilation first, detection, and operation later" ...
