Medical Waste Incineration Furnace Computer Monitoring System Of Research And Development

The Medical Garbage Incinerator in HuZhou City is a demonstrative project, which is developed by the Institute of Thermal Power Engineering of Zhejiang University. To ensure the feasibility of medical garbage incinerator system, a steady and dependable monitoring and controlling system is very necessary. According to situations of the medical garbage incinerator, this paper does deeply research on the thermal monitoring-controlling system, while considering of advanced technology and experience domestically and abroad. The key points of this paper include the design of software and hardware of the system, and the realization of automatic control function.The monitoring-controlling system adopts a total distributed control system (DCS) constituted by a programmable logic controller (PLC), a computer (PC) and thermal power engineering signal sensors, senders, controllers, etc. This system can monitor thermal parameters and perform automatic control. The PLC is used to collect thermal parameters' data and achieve automatic control, while the PC is adopted to monitor the operation process and data process by communicating with PLC. This system enables the control system to be operated safely and reliably, and then brings many conveniences to the operator.This paper contents software development of PLC and PC. The software for PC is developed by King View to be effective and friendly to operators, which can realize many functions such as list-display of thermal parameters, process display, alarming, history querying, and automatic setting, etc. The software for PLC is programmed by STEP-7, which completes data transferring and auto-control functions. What's more, this control system uses intelligent PID controller to design all automatic control loops.Through this project, I hope to supply a good way for building a good small real-time thermal engineering monitoring-controlling system.
