The Research On Dynamic Match Method For LNG Element And Testing System Design

Along with the use of Liquefied Petroleum Gas and gas in daily life, gas testing becomes more and more important. At present, LNG catalytic sensor was extensively used in the alarming system of coal mine gas testing and indoor nature gas testing. Gas sensor enterprises product thousands of components every day。But, a lot of operation of the testing equipment need handwork at present, the degree of automation is low, it can not complete such a large task. For increasing the quality and the reliability, and cutting down the cost of production, a set of dynamic match batch testing separation system with high precision in testing and fast in speed needs to be developed.Combine with the research of the project and the actual application, we introduced the influence of the compensating element on the output characteristic of the carrier catalytic element that takes LNG catalytic element and compensating element as the research object. We adopted the match method which based on clustering method of modern mathematics and designed the dynamic performance parameters testing system of LNG elements.The studies of the paper are as follows:1. Through the experiment and theory analyze, we adopted clustering method of modern mathematics and as the match method of element dynamic parameters.2. MSP430 MCU is the core equipment. We designed the match batch testing separation system of LNG element dynamic parameters which have a match according to the dynamic parameters for improving the stability and resisting disturb ability.3. We designed the MCU software according to the need of the testing system function. During designing the software, we fully considered the combine with the system hardware circuit. From the firmware program of MCU, we achieved the switch of many troops invariableness under the controlling of MCU. The MCU software adopted blocking design, such as key-press function; display function; data collection and disposing function; USART communication function.The system can provide whole testing information of LNG element and resolve practical problems during the matching of catalytic element and compensating element. It can save a lot of time, short the cycle of homologous soft system development and improved the efficiency. So the design of this system has assumed both theoretical significance and practical value.
