Esign And Implementation Of The Industrial Ethernet Data Collector

In recent years, the related technology obtained the vigorous development about the Internet of things, however, in the industrial field, there are a lot of equipment of control needs to communicate with network, reach to the control effect, at the same time, the development of Ethernet technology has been fully, it provides the basis for the development of embedded Ethernet technology and the wizard. In the field of industrial control, it is a lot of equipment is to receive, send data through Ethernet. In industrial environment, however, there are high voltage, high current, high temperature, and so on unfavorable factors in everywhere, these factors will affect the controller all time, it might damage the controller or increase the controller transfer probability of false information. Now, on the market the price of various data collector is very expensive, and technology is secret, and the general is very poor. in future, however, data collector will be more employ extensive, so this kind of phenomenon should not be appeared. As a result of the existence of these factors, we put forward the topic of this article that is a new kind of industrial Ethernet data collector design and implementation.Through long-term research, finally determined to have Cotex-M3kernel STM32F107series single chip microcomputer as industrial Ethernet data collector for processor, at the same time, choose a series of development and debugging tools to create a research and development platform, here we select Python, Keil, Modbus Salve, SecureCRT, such as development tool, and the real-time operating system RT-Thread and LwIP TCP/IP protocol stack and Modbus protocol Lib-Modbus as industrial Ethernet data collector software foundation. Through a combination of these software, we can write various peripheral device driver and application software, including read and write Flash drive, the TCP client application, a serial port application, eventually achieve industrial Ethernet data collector communicate with Ethernet.Through repeated testing, improving, testing, successfully tested industrial Ethernet data collector, such as collection, transmission and monitoring, and do the related function and performance debugging, in addition to reading and writing more keep register, data collection and transmission, and other basic functions. The downside is that in the design of the client display do not perfect, is rough. In the aspect of hardware circuit design, the protection of the whole circuit is not perfect, not able to do the test in some specific circumstances, when the data collector facing bad environment, the accuracy is unknown about data acquisition and transmission.
