3000W online control switch PCBA

The intelligent plug-in control system based on single-chip microcomputer, this design adopts Cortex-M3Single-chip microcomputer as the control core, the system has the functions of voltage and current detection, over-current protection, multi-channel timing on-off control, automatic saving of power-off timing time, etc.The system is divided into three interfaces: main interface, timing interface and query interface.in the remotePConline andAPPSend relevant instructions, control the opening and closing of the socket, check the current equipment operation status, etc., if the equipment is abnormal, start the insurance user mode and send relevant alarm signs,This design has the functions of saving energy, eliminating potential safety hazards, and prolonging the life of household appliances, which brings great convenience to life..
PCBAdivided into 2 parts
systematiccontrol,hardwareand softwareThe system is mainly composed of the main controller module, the electric energy metering module,Flash storage module,(Internet Server API)ISAPI,Composition of relay control module.Through the single chip microcomputer for data processing, timing control,Flash storage module control, electric energy acquisition and overcurrent protection. In order to realize the energy consumption monitoring of electric equipment, the electric energy data is detected through the electric energy metering module. Overcurrent protection function, and display the power data through the LCD liquid crystal display. The RTC clock module mainly provides accurate time for the system. The Flash storage unit is mainly used to storeStore the timing time and the running state before power failure, so as to realize the function of saving data after power failure and restoring the power-on state.

When the equipment is running, the full load is3000W power, more than 3000W start protection mode, stop operation. At the same time send relevant reports to ensure equipment safety.
