Processing Circuit

A kind of multiple parameter data acquisition system was designed based on single-chip microcomputer which can realized the data acquisition of temperature and DC motor speed. The data acquisition system consists of sensor, signal processing circuit, single-chip microcomputer and LED digital tube. The speed signal is acquired by photoelectric sensor, put into the Single-chip microcomputer processed after processed by signal processing circuit, and displayed the value in the digital tubes. The temperature signal is acquired by digital sensor, and the Single-chip microcomputer can read the data directly. Through two independent keyboards, the test system realized the data acquisition and data switch displaying of the multiple parameters.

Set Up

To improve the reliability and integration of relay protection devices in power, the system on chip design for multi-principle of relay protection on FPGA is proposed. The data acquisition, digital signal processing, hardware protection algorithm, FPGA and MCU process scheduling, MCU and peripheral devices communication are designed, the hardware compilation model is set up by QuartusII on FPGA, and the simulation and experimental verification are performed. The results show that the proposed system can improve the speed of hardware protection and reduce the volume of the device, and has reconstruction on architecture.
