Abstract

The invention discloses a bus protection device sampling board automatic detection system and a detection method thereof. The system comprises a power supply board, a CPU board, a detection board, a sampling board, a backboard and a display screen, wherein the power supply board provides working voltage for other board cards in the system; the CPU board communicates with the detection board, the sampling board and the display screen to control the detection process of the whole system; the detection board is communicated with the CPU board and the sampling board, generates direct current and alternating current output quantities, receives an output signal of the sampling board and judges a detection result; the sampling board communicates with the CPU board and the detection board, collects analog quantity, converts the analog quantity into digital quantity and outputs the digital quantity; the backboard provides electrical connection for other board cards in the detection system; and the display screen communicates with the CPU board and is responsible for completing man-machine interaction in the detection process.

Description

technical field [0001] The invention relates to an automatic detection system and a detection method for a sampling board of a bus protection device in the field of relay protection. Background technique [0002] The busbar protection device is a kind of relay protection equipment used in substations to protect the safe operation of the busbar in the substation, so the reliability of the busbar protection device is very important. The protection function of the busbar protection device is based on the analog data collected by the sampling board, so it is necessary to develop a sampling board detection system to ensure that the function of the sampling board meets the standards of relay protection and power industry. [0003] The existing sampling board testing devices and methods generally adopt the serial port communication mode, and the data transmission efficiency is low; and the existing testing method has a complex structure and includes steps such as setting parameters...
