This paper presents a washing machine controller based on field programmable gate array (hereinafter referred to as FPGA). This washing machine controller not only has stable performance, strong anti-interference ability and simple structure, but also occupies less hardware resources. It can satisfy the control requirements of different types of washing machines by configuring system parameters,

Wide-area oxygen sensor can accurately describe the exhaust concentration state, which is more advantageous than traditional oxygen sensor. Based on the principle of wide-area oxygen sensor, the controller of wide-area oxygen sensor is designed from hardware and software. The relationship between the output voltage and the excess air coefficient was established by calibrating the controller.

Programmable Logic Controller is short for Programmable Logic Controller in Chinese. With the rapid development of information technology and hardware performance of programmable logic controller in recent years, the requirement of real-time communication between upper equipment and PLC has been constantly improved. Besides the continuous improvement of hardware configuration performance of PLC, what communication mode

Vehicle air conditioner controllers mostly use traditional physical and mechanical keys.
