【Abstract】 The early zirconia products are analyzed and summarized,and targeted improvements and upgrades are made. A new type of high-performance oxygen transmitter is designed and developed by using intelligent and modular methods. The hardware adopts a high-performance microprocessor system,and the system is composed of extended digital potentiometer,watchdog,RS485 communication and other modules. The software adopts the algorithm of automatic timing restart,weighted filtering and queue filtering,and the combination of redundant fault tolerance,digital communication and other technologies. The design gives full play to the data processing capacity of 32-bit CPU and the performance of external equipment,and adopts the method of combining hardware and software,which greatly improves the reliability,ease of use and intelligent level of the equipment.更多还原
