针对市场上煤炭燃点测定仪测量精度低,试验过程可视化效果不好等缺陷,设计了一种新型煤炭燃点测定仪。系统利用ModBus传输协议和CRC16位校验技术实现了上位机与下位机的通信。上位机采用温度数字过滤程序,同时结合下位机采用冒泡排序法,滤除了温度突变值,解决了温度探头可能有较大突变而带来的误差问题,保证了燃点测定的精确可靠,本系统界面设计友好,可视化效果佳且操作更为方便。
In view of the defects of low measuring precision and poor visualization effect of the coal ignition detector on the market, a new type of coal ignition detector is designed. The system uses ModBus transmission protocol and CRC16 bit verification technology to realize the communication between upper computer and lower computer. The upper computer uses the temperature digital filter program, combined with the lower position machine uses the bubble sort method, filters out the sudden change of temperature, solves the temperature probe may have a greater mutation error brought about to ensure the ignition point determination is accurate and reliable, the system Friendly interface design, good visualization and more convenient operation.
