Natural gas vehicle gas wireless monitoring controller based on CC2530 and control method thereof

Abstract

The invention discloses a natural gas vehicle gas wireless monitoring controller based on CC2530 and a control method thereof. The natural gas vehicle gas wireless monitoring controller comprises a gas wireless control valve node, a wireless coordinator node and N wireless monitoring nodes, wherein N is at least 1; every wireless monitoring node of the N wireless monitoring nodes comprises a gas sensor, an ADC (Analog to Digital Converter) module, a microprocessor and a wireless communication module; the gas wireless control valve node comprises a microprocessor, a wireless communication module and a gas control valve; the wireless coordinator node comprises a coordinator master control unit, an LCD (Liquid Crystal Display), a data storage, a sound and light alarm module and a wireless communication module; and the LCD, the data storage, the sound and light alarm module and the wireless communication module are connected with the coordinator master control unit respectively. According to the natural gas vehicle gas wireless monitoring controller based on the CC2530 and the control method thereof, detection and monitoring need to be performed on a plurality of vehicle sensitive points which are easy to cause gas leakage according to actual situations of a natural gas vehicle, so that real-time detection, early warning and control on natural gas concentration inside the natural gas vehicle can be achieved.

Description

technical field [0001] The invention relates to a gas monitoring system, in particular to a CC2530-based wireless gas monitoring controller for natural gas vehicles and a control method thereof. Background technique [0002] With the rapid development of my country's national economy, the sharp increase in car ownership, and the severe situation of oil resources and environmental protection, the development of natural gas vehicles has become an important way to solve energy and environmental problems. However, during the promotion of natural gas vehicles, people are worried about the safety of natural gas vehicles, especially CNG (Compressed natural gas: compressed natural gas) vehicles. This is a misunderstanding. Of course, natural gas is a colorless, odorless, explosive gas, and it is difficult to detect when a leak occurs. But the explosion of natural gas is conditional, precursory and predictable. A small amount of gas leakage will form a low concentration in the air...

AI Technical Summary

Problems solved by technology

However, if there is a lack of monitoring, a large amount of gas leaks or slowly accumulates, a relatively high concentration of flammable gas will be formed in the air. Once it reaches a certain level, there will be a danger of fire and explosion when encountering open flames or sparks
