Abstract:

According to the analysis on the traditional power quality pickup assembly,a power quality monitor and data storage system based on CAN bus is proposed.This system designs a fast data transmission platform which can transmit a tremendous amount of data reliably and realize efficiently data communication between the base station and host computer system.Meanwhile,the system can achieve large memory of data by externally enlarging the storage of hard drive with the U-disk read-write module.In addition,these modular circuits for data acquisition,phase-locked frequency multiplication and data communication are also given.The test results show that this system is feasible and all parameters satisfy the design requirements.
