| Abstract: | As a reducing agent,CO gas is widely used in industrial metallurgy and other scenes. In industrial production,atmospheric monitoring and poisoning early warning,the detection of CO is essential. TDLAS technology can efficiently and accurately detect specific gas concentration. CO detection based on TDLAS has apparent advantages over other traditional detection methods. In this design,LPC55S69 is used as the central control,and VCSEL is used as the core light source to realize CO gas detection of TDLAS. As the detection environment becomes complex,the method’s limitations based on field detection become larger. The design also designs the wireless encryption transmission mode of the detection data according to the needs. LPC55S69 adopts a 128-bit AES-ECB algorithm to encrypt data and upload data to PC through Wi-Fi( ESP8266). After decryption,the PC can get the gas information to be measured. Use remote data encryption transmission technology by this method dramatically broadens the application range of TDLAS CO gas detection. Besides,it also made the transmission more secure. |
