The PID controller adjusts the deviation of the whole control system according to the principle of PID control, so that the actual value of the controlled variable is consistent with the predetermined value of the process requirements. Different control laws are applicable to different production processes, and the corresponding control laws must be reasonably selected,

Metro environment and equipment monitoring system can effectively monitor and control the mechanical and electrical equipment of the station, such as ventilation and air conditioning system, water supply and drainage system, vertical elevator and escalator, low voltage distribution lighting and so on. 　　The Digital input-output interface of the controller in the environment and equipment monitoring

Nowadays, in the situation of the gradual development of smart grid, the state has put forward stricter requirements for the economy and safety and reliability of power production, transmission and distribution. Distribution network is the terminal of the whole transmission system, which connects many power users. It is also the key to restrict the performance

Raymond mill is an important grinding equipment. It is very important to design and improve it scientifically and effectively, so that it can feed automatically, which is conducive to improving production accuracy and efficiency, and also conducive to saving resources. This paper designs a controller of Raymond mill automatic feeder based on STM32 single chip

In today’s energy shortage, the application of new energy technology has attracted much attention. Solar street lamp system directly uses solar energy as energy, which is not constrained by the city power grid, easy to install and does not consume conventional energy. 　　It is especially suitable for the urban-rural junction where transportation and ordinary power

Dayang Street Lamp is widely recognized for its advantages of no cable laying and no conventional energy consumption. However, there are still some problems in solar street lamp, which lead to high cost and unstable reliability. For example, batteries often need to be replaced in less than a year. This not only increases the cost
