摘　　要：针对现代工业环境中监控系统精度不足、监控范围受限、响应机制差等问题,本文以工业环境中常见的热气机为主要对象,基于PIC18F6722单片机作为逻辑控制算法核心,设计了一种针对热气机加热端管壁温度以及燃烧室压力的监控系统,详细阐述了该监控系统的整体设计思路,细致分析了其硬件设计、控制机制以及软件设计,同时利用PC机作为该系统的上位机,贴合相关运维管理人员的作业需求设计了人性化的人机交互界面。结果表明,该系统对热气机加热端管壁的温度控制精度能维持在±5℃内,针对热气机燃烧室的压力可将其控制在2.8±0.025 MPa内。此外,应用该系统后,还能将既有排气阀的有效使用时间延长至6倍以上。Considering the issues of insufficient accuracy,limited monitoring range,and poor response mechanism in modern industrial environments,this paper focuses on common hot gas engines in industrial environments.Based on the PIC18F6722 microcontroller as the logic control algorithm core,a monitoring system is designed for the wall temperature and combustion chamber pressure at the heating end of the hot gas engine.After elaborating on the overall design concept of the monitoring system,the hardware design,control mechanism,and software design were analyzed in detail.At the same time,a PC was used as the upper computer of the system,and a humanized human-machine interaction interface was designed to meet the operational needs of relevant maintenance and management personnel.The results show that the temperature control accuracy of the heating end tube wall of the hot gas engine can be maintained within±5℃,and the pressure of the combustion chamber of the hot gas engine can be controlled within 2.8±0.025 MPa.In addition,after applying this system,the effective use time of the existing exhaust valve can be extended to more than 6 times.
