摘要
针对常规风机过滤器单元(FFU)群控系统存在布线复杂、成本和故障率高、抗干扰能力差、工作不稳定、维护困难等缺点,提出了一种新的基于无线和电力线载波通信(PLC)技术的新型FFU群控系统。该系统通过PLC技术,将同一车间供电线路上的各个测控单元汇集到无线数据收发控制节点,再利用无线通信网络与监控管理中心进行组网。详细介绍了系统的组成及软硬件实现,并进行了试验运行测试和工程应用。试验结果表明,该群控系统有效地解决了常规群控系统组网布线难、可扩展性差和可靠性低等问题,具有较高的应用价值。
Aiming at the shortcomings of existing conventional group control system of the fan filtering unit （ FFU ）, for instance, complex wiring, high cost and failure rate, poor anti-interference capability, instabihty of operation, and hard to maintain, etc, on the basis of wireless and PLC technology, a new type of group control system for FFU is proposed. In this system, PLC technology is used to converge all the measurement and control units on the common power line in the same workshop into the wireless data transceiver control nodes, and then the wireless communication network and monitoring management center are adopted to accomplish networking. The composition of the system and the implementation of hardware and software are introduced in detail, the experimental nmning test and engineering application are carried out. The results of the application show that this group control system selves the problems existing in conventional systems, and it possesses higher applicative values.
