基于CAN总线的臭氧发生器远程监控系统的研究与设计
|
摘要
由于臭氧在杀菌消毒方面的广泛应用,使得臭氧发生器行业得到了巨大的发展,但单台的臭氧发生器的产量仍然很低,所以自来水厂、污水厂一般为多台同时使用,但是至今为止,还没有成熟的多台臭氧发生器的远程监控网络系统,本论文就是在这样的背景下,研究使用CAN总线实现多台臭氧发生器的远程监控。
现在用的大型臭氧发生器本身为一个复杂的系统,且在运行过程中,具有多个模拟量和开关量参数,不具备挂入总线的能力。为了实现该监控系统,必须完成以下三个任务:臭氧发生器组入CAN网络的物理条件、实现CAN通信的协议条件和上位机监控的软件条件。本论文也主要围绕这三方面展开。
首先,根据臭氧发生器的特点,利用ARM7处理器LPC2129设计了含有CAN控制器和收发器的智能节点,该智能节点的主要功能为:数据采集、LCD显示、报警、与CAN网络通讯、控制发生器的运行状态等。利用该智能节点,把数据发送至CAN网络的同时,管理人员也可在现场查看发生器的实时运行参数信息。
其次,根据CAN2.0B规范,设计合适的CAN通信协议。根据传输内容不同,对标识符进行分配;在智能节点中对臭氧发生器的不同参数进行组合发送;主机用数据帧的不同的数据表达不同的命令要求;同时对LPC2129的接收滤波器进行设置,使其只接收广播帧和固定的某些报文。
最后,用MCGS组态软件设计了主机的监控软件,这里主要介绍了监控软件中的数据处理部分,包括了对接收的数据进行类型转换以及目标数据库的转存。从小容量的数据库转入大容量的数据库SQL Server 2000,并对目标数据库进行优化和维护,更能保障整个监控软件的后台数据库的正常运行。
以上三个方面相互结合,才构成完备的臭氧发生器的远程监控系统。
With the widely application of the ozone in the sterilization, the Ozonizer industry has a large development. But the output of single ozonizer is low, so the waterworks and the sewage farms always use several ozonizers at the same time. There is no case of the successfull control system of the ozonizers until now. In this background, the article researchs the control system by using the CAN bus.
The ozonizer is a complex system by itself which has many analog and digital parameters when running. And it does not have the capacity to hang up the CAN bus. So we have to meet three conditions if we want to realize the system. They are the physics condition to let the ozonizer connect with the CAN bus、the protocol condition to realize the CAN bus communication and the software condition. This text expands surrounding the three conditions.
Firstly, I design the smart node using the LPC2129 of ARM7 for the ozonizer connecting with the CAN bus. This smart node includes the CAN controller and the transceiver. The main ability of the node is data collection、LCD display、sound alarming、connecting with the CAN bus、controlling the state of the ozonizer. Using the node, the user can watch the running information in the field as while as the data was sent to the main node.
Secondly, design the protocol of the CAN communication according to the standards of CAN2.0B. Define the ID according to the sender; Send the combination of the different parameter in the smart nod; Use the different data to deliver the different order in the host computer. At the same time, set the acceptance filter of the LPC2129. Then it can only receive the broadcast frames and the special frames. In the end, design the control software of the host computer using the MCGS. There I mostly introduce the part of the data processing. The part includes the data transform and the changing of the aim database. Change the database from the little capacity to the big one SQL Server 2000、optimize and maintain the aim database. The database can run well and longer from this way.
To sum up, we can form a complete remote monitor and control system of the ozonizer with the mentioned above.
