[0015] Example

[0016] Such as figure 1 As shown, the wireless natural gas detector of the present invention is mainly composed of a microcontroller, a gas sensor, a power supply, a display, an alarm, a storage and a wireless receiving circuit connected to the microcontroller, and A connected to the gas sensor. / D conversion chip, and a wireless transmitting circuit connected with the A / D conversion chip; the wireless transmitting circuit is connected with the wireless receiving circuit through a wireless network.

[0017] Among them, the gas sensor adopts the MD61 type natural gas sensor produced by Shanghai Meisi Electronic Technology Co., Ltd., which has high sensitivity, long life and low cost. The A / D conversion chip is used to convert the analog signal output by the gas sensor into a digital electrical signal, and the ADC0809 type A / D conversion chip is preferred. The EOC pin of the ADC0809 type A / D conversion chip and the output terminal of the gas sensor The ALE pin is co...

Abstract

The invention discloses a wireless natural gas detector. The wireless natural gas detector is characterized by mainly comprising a microcontroller, a gas sensor, a power supply, a display, an alarm, a storage, a wireless receiving circuit, an A/D (analog to digital) conversion chip and a wireless transmitting circuit, wherein the power supply, the display, the alarm, the storage and the wireless receiving circuit are connected with the microcontroller, the A/D conversion chip is connected with the gas sensor, and the wireless transmitting circuit is connected with the A/D conversion chip; the wireless transmitting circuit is connected with the wireless receiving circuit through a wireless network. Signals are transmitted through the wireless network, detection personnel can detect whether natural gas leakage happens or not without presenting in the detection site, and accordingly a safety guarantee is provided for the detection personnel. The signals are transmitted through the wireless transmitting circuit and can be processed by the same to be more stable in the process of long-distance transmission, so that the distance of signal transmission is longer.

Description

technical field [0001] The invention relates to a detector, in particular to a wireless natural gas detector. Background technique [0002] As natural gas becomes more and more popular, people pay more and more attention to the safety of natural gas use. Nowadays, people usually use portable natural gas detectors to detect whether natural gas leaks. However, natural gas itself has the characteristics of rapid diffusion and easy explosion. , the leakage point will expand rapidly, and a large area of ​​disaster risk area will be formed in a very short period of time at the accident site. When people use traditional portable natural gas detectors to detect natural gas leakage, if the detection personnel cannot Evacuation will easily lead to poisoning of on-site inspection personnel. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the traditional natural gas detector can only be used at the detection site and bring perso...
