On September 10, Chongqing Chuanyi Automation Co., Ltd. undertook the acceptance of the "863" project, "Online Detection Technology and Instruments for Process Industry-oriented Sewage Discharge", which passed the acceptance of the Ministry of Science and Technology and achieved a series of results.

One is to master the design and manufacture of sensors and instruments, and the modular design series technology, and proposed a modular multi-layer structure gas-related receiver design method, which improves the infrared gas detection sensitivity and gas selectivity; the second is to propose automatic correction of laser line broadening and The temperature and pressure compensation method improves the measurement accuracy of the measured gas pressure and temperature change environment; the third is to propose a multi-optical path, high-speed sampling and double division digital filtering detection method for space-time separation, which improves the sensitivity and stability of ultraviolet gas detection The fourth is to propose a high-speed integration and flow rate fluctuation compensation algorithm, high-temperature catalytic combustion and automatic electronic condensation method, which realizes TOC detection of large-volume injection, low detection limit and high repeatability; fifth is to optimize precision polishing, aluminum alloy gold plating, Manufacturing processes such as metal adhesive sealing and high vacuum interference gas analysis convection emissions have improved the stability of key components. Sixth, BO2000-GXH intelligent modular infrared gas analyzer and other 8 series of products have been developed. The technical parameters of the products have passed the national legal Institutional testing, achieved sales revenue of 102 million, and more than 36 engineering applications.
