【摘要】：ZigBee是一种新兴的短距离无线通讯技术，是随着工业自动化对于无线通信和数据传输的需求而产生的，是一组基于IEEE802.15.4无线标准研制开发的有关组网、安全和应用软件方面的通信技术。它的网络具有省电、可靠、成本低、容量大、安全等诸多优势。目前ZigBee的使用范围非常广，可以应用在消费电子品、家居与楼宇自动化、工业控制、医疗设备等各种领域。Modbus协议是应用在工业控制系统中最广泛的一种通信协议标准，是全球第一个真正用于工业现场的总线协议。此协议支持传统的RS-232、RS-422、RS-485和以太网设备。许多工业设备包括PLC、DCS、智能仪表等都在使用Modbus协议作为它们之间的通讯标准。有了它，不同厂商生产的控制设备可以连成工业网络，进行集中控制。针对传统人工采集数据费时费力和有线监控布线复杂的情况，为了提高工农业管理的网络化和智能化水平，降低生产过程中的工作量，又针对ZigBee网络和Modbus协议的特点，课题设计了一个基于ZigBee无线通讯技术和Modbus协议相结合的无线远程监控系统，首先让传感器采集现场数据并发送给ZigBee模块。然后，ZigBee模块之间形成强大的ZigBee网络，数据就通过ZigBee网络传送给ZigBee网络的协调器上。最后，协调器利用WIFI网通过Modbus协议的形式把数据传送到PC机上。上位机采用力控组态软件进行界面控制，可以更直接、简单地查看现场的情况。该设计适应了工业控制领域的数字化、智能化、网络化的发展。
[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.
