Abstract:Aiming at the characteristic of multiple models, large quantity, long maintenance cycle, difficult detection and maintenance in the testing and maintenance process of a large phased array radar, a portable power detection and maintenance system was designed to solve these problems. The system is composed of an FPGA core board, a data acquisition board and an ePC-k70-lite-L integrated module. According trouble clearing experience of maintenance, analyzing the collected data of fault diagnosis software , fast detection and maintenance of multiple kinds of power supply failure are supported . The system can realize online control, parameter reading and assignment of 13 power supplies of three types of a certain type of radar, and can realize online monitoring of up to 7 groups of power parameters at the same time. The test time is shortened from 5 minutes to less than 10 seconds, and the power detection accuracy rate is Up to 99%, without relying on external power supply, work continuously for more than 5 hours. Since the system has been put into use for 4 years, it has been stable in operation and easy to operate and maintain. It has tested and repaired various types of power supplies for more than 800 times, which has greatly improved the equipment's independent support capability and maintenance efficiency, and improved the success rate of equipment mission execution.
