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

The control method of CNC valve spool end grinder is introduced in this paper. The grinding method of valve spool end face was studied. The methods of dressing wheel with diamond pen and automatic compensation for dressing are studied. The display, thermostatic element control and management of valve spool end grinding are numerically controlled by

Actuator controller has an important application in robot control technology. Its performance is directly related to the normal operation of multi-actuator system. In order to solve the contradiction between multi-output and high precision of servo controller designed with control chip, a new servo controller is designed. The hardware adopts high performance STC15F2K60S2 single chip computer,

LM555 is a widely used analog-digital hybrid (i.e. bipolar) integrated circuit. Based on the LM555 control circuit, this paper studies the timing and control integrated circuit. LM555 timer constitutes a multi-resonant oscillator. In the control circuit, the duty cycle of output waveform is regulated by the potentiometer, and the start-stop time of load operation is

Programmable controller is essential in industrial control, so PLC course is a very important professional course. This course requires logical thinking, and we know that PLC has many programming methods, such as instruction list, ladder diagram and sequential function diagram. Because everyone has different thinking modes, the implementation of each project is also different. 　　Today,

In this paper, the author visited DEVI (Denver, the world’s largest supplier of heating equipment and control parts) in Denmark in March 2003 to investigate the intelligent control manufacturing technology of floor radiant heating system, and combined with the customer feedback of the intelligent heating system temperature controller installed and used in Shanghai area for

Biomass stove is an energy-saving stove with biomass as fuel. It is a multi-variable input and output control system with pure lag and time-varying thermal inertia. Aiming at the problems of low combustion efficiency of biomass and large emission of harmful gases, a hybrid controller combining PID control and fuzzy control is designed by using

At the “2018 China Semiconductor Market Annual Conference and IC China Summit”, three local memory or memory controller manufacturers that have mass-produced chips introduced the relevant market technology trends and product strategies.These three enterprises are: Beijing Zhaoyi Innovation, Shanghai Hualan Microelectronics and Beijing Yixin Technology.Mr. Su Zhiqiang, Director of Strategic Marketing Department of Beijing Zhaoyi
