[Abstract]:The hardware and software configuration of the mainstream products in the field of computer monitoring and control, which is mature in the market at present, is adopted. On the new cement dry process production line, the configuration software and wireless sensor technology are combined. The energy consumption reduction monitoring system is designed. On the basis of not affecting the automatic production control system of the enterprise, the signal can be obtained by using the original on-line instrument of the production line through wireless communication. Through wireless network transmission to configuration software monitoring screen display real-time data to realize the new dry process cement production line energy consumption and emissions real-time online monitoring. This paper mainly studies the characteristics of wireless sensor networks with ZigBee as the core, explains the main advantages of use, and is familiar with the production characteristics and processes of cement plants. Considering the adaptability of the system to the complex and harsh environment of cement production, the system has the ability of anti-interference and anti-multipath interference, and improves the reliability of communication. Through the direct sequence spread spectrum technology, DSS, CSMA-CA mechanism and confirmation mechanism, To ensure the stability of wireless signal transmission, CC2530 is chosen as the main chip in the system hardware. Based on the structure and function of CC2530, according to the field signal type of cement plant, the 4-20mA signal of analogue quantity is focused on, and the output interface with the field instrument is given to collect the signal separately. The interface form of Ethernet is given by RS232 serial port. In order to improve the usage time of chip, provide external power supply hardware form and consider its expansibility, it can realize 15-24VDC wide DC power access. The main source code and code program are given briefly. The main work flow of each node of wireless network. The real-time on-line monitoring adopts Kingview 6.5 software, combined with the equipment and technology of cement production line, the basic monitoring picture is given, and the real-time monitoring of the field data is established, and the overvalued alarm is given. Report and other basic functions, in order to improve security, set system permissions.
