【摘要】：ZigBee是一種新興的短距離無線通訊技術，是隨著工業(yè)自動化對于無線通信和數據傳輸的需求而產生的，是一組基于IEEE802.15.4無線標準研制開發(fā)的有關組網、安全和應用軟件方面的通信技術。它的網絡具有省電、可靠、成本低、容量大、安全等諸多優(yōu)勢。目前ZigBee的使用范圍非常廣，可以應用在消費電子品、家居與樓宇自動化、工業(yè)控制、醫(yī)療設備等各種領域。Modbus協議是應用在工業(yè)控制系統中最廣泛的一種通信協議標準，是全球第一個真正用于工業(yè)現場的總線協議。此協議支持傳統的RS-232、RS-422、RS-485和以太網設備。許多工業(yè)設備包括PLC、DCS、智能儀表等都在使用Modbus協議作為它們之間的通訊標準。有了它，不同廠商生產的控制設備可以連成工業(yè)網絡，進行集中控制。 針對傳統人工采集數據費時費力和有線監(jiān)控布線復雜的情況，為了提高工農業(yè)管理的網絡化和智能化水平，降低生產過程中的工作量，又針對ZigBee網絡和Modbus協議的特點，課題設計了一個基于ZigBee無線通訊技術和Modbus協議相結合的無線遠程監(jiān)控系統，首先讓傳感器采集現場數據并發(fā)送給ZigBee模塊。然后，ZigBee模塊之間形成強大的ZigBee網絡，數據就通過ZigBee網絡傳送給ZigBee網絡的協調器上。最后，協調器利用WIFI網通過Modbus協議的形式把數據傳送到PC機上。 上位機采用力控組態(tài)軟件進行界面控制，可以更直接、簡單地查看現場的情況。該設計適應了工業(yè)控制領域的數字化、智能化、網絡化的發(fā)展。
[Abstract]:ZigBee is a new short-range wireless communication technology, which is produced with the demand of industrial automation for wireless communication and data transmission. It is a group of related network based on IEEE802.15.4 wireless standard. Communication technology in security and application software. Its network has power saving, reliable, low cost, large capacity, security and many other advantages. At present, ZigBee is widely used in many fields, such as consumer electronics, home and building automation, industrial control, medical equipment, etc. It is the most widely used communication protocol standard in industrial control system. Is the world's first real industrial field bus protocol. This protocol supports traditional RS-232 RS-422 RS-485 and Ethernet devices. Many industrial equipment, including the Modbus, smart instruments, and so on, are using the Modbus protocol as their communication standard. With it, different manufacturers of control equipment can be linked to the industrial network, centralized control. In order to improve the networked and intelligent level of industrial and agricultural management and reduce the workload in production process, aiming at the characteristics of ZigBee network and Modbus protocol, the traditional manual data collection is time-consuming and laborious. A wireless remote monitoring system based on ZigBee wireless communication technology and Modbus protocol is designed. Firstly, the sensor can collect the field data and send it to the ZigBee module. Then a powerful ZigBee network is formed between the ZigBee modules, and the data is transmitted to the coordinator of the ZigBee network via the ZigBee network. Finally, the coordinator uses WIFI network to transmit data to PC through Modbus protocol. The upper computer uses the force control configuration software to control the interface and can view the situation more directly and simply. The design adapts to the development of digitization, intelligence and networking in the field of industrial control.
