[Abstract]:Since joining the WTO, the country's demand for coal has been increasing. Driven by interests, the phenomenon of super-capacity production is common in the coal mine industry. Ultra-capacity production not only brings a series of safety problems, but also brings about tax evasion in coal enterprises. Based on the application project of the remote coal production and marketing monitoring system of a city coal administration in Shandong province, this paper designs the embedded Ethernet measurement and control terminal, which is needed for the project. The terminal can obtain the coal mine production and sales in real time and upload it to the management center of coal bureau, so that the management department can monitor the occurrence of super-capacity production from the source. Firstly, the application requirements of Ethernet measurement and control terminal are analyzed, and STM32F107 microcontroller is selected as the embedded master chip, LwIP as the embedded TCP/IP protocol stack, and FreeRTOS as the real-time operating system of the project. Then the specific hardware and software design is carried out. The hardware design part includes: low-voltage power supply system, main control circuit, communication interface, anti-interference circuit and so on. Firstly, the software platform is built, including FreeRTOS real-time operating system migration, Ethernet communication driver migration, RTC driver design, etc. Then, according to the requirements of the project, the production and marketing data acquisition is realized on the operating system platform. Ethernet communication, data U disk reading and writing, human-computer interaction and abnormal alarm tasks. Then, through the measurement and control terminal test, further verify the feasibility of the design. At the same time, the Ethernet communication task, the weight data selection algorithm and the coal carrier transportation direction discrimination algorithm are improved according to the actual operation on the spot. Finally, the embedded Ethernet measurement and control terminal is summarized and prospected. As a typical application of Internet of things-related technology, this paper applies embedded Ethernet technology to coal mine production and sales monitoring field, which can make the obtained production and marketing information more real-time, accurate and comprehensive, in line with the development requirements of the information age. It has certain research significance.
