摘　　要：以智能处理器为核心,应用嵌入式技术设计并开发的电伴热智能控制器可以监测管道温度、回路电流和断路器状态,并根据工艺要求控制每条电伴热加热回路。同时,各控制器之间可以通过485总线或局域网连接成工业控制网络,使得每个智能控制器可控制多达320条加热回路,克服了以往电伴热控制器在扩展性及回路控制灵活性方面的不足。此外,该控制器通过对采集数据的分析,可以自诊断出运行故障及报警产生的原因。经试验测试表明:该电伴热智能控制器运行稳定,具有较好的系统扩展性和兼容性,并在回路控制的有效性上表现出较好的性能。An electric heat-tracing intelligent controller which use of intelligent processor and application of embedded tech- nology was designed and developed. The controller can monitor the pipeline temperature,loop current and the status of breaker, and can control every electric heating-circuit according to process requirements. Compared with other controller, the intelligent controller can control up to 320 circuits with multiple controllers through RS -485 industrial bus or local area network,and it overcome the deficiency both in expansibility and control flexibility aspects. A well functioned fault diagnosis and alert solution was applied to the intelligent controller. The results of experiments show that the electric heat-tracing intelligent controller has a good system scalability and compatibility. And it shows better performance in effectiveness of communication and heating-circuit control.
