Abstract

The invention provides a CPCI bus board card. The board card comprises an MCU and a first measuring unit. The first measuring unit comprises a high-voltage recovery module, a leakage current recoverymodule, a high-voltage generator module and a leakage current balance bridge module. The high-voltage generator module is used for generating a voltage with a set value and applying the voltage to a coil of the tested electromagnetic valve. The high-voltage recovery module is used for collecting the voltage of the shell of the tested electromagnetic valve and sending the collected first data to the MCU. The leakage current balance bridge module is used for collecting leakage current of a shell of the tested electromagnetic valve, converting the leakage current into voltage to obtain second data and sending the second data to the leakage current recovery module. The leakage current recovery module is used for sending the second data to the MCU. The MCU is used for determining the insulationcharacteristic of the tested electromagnetic valve according to the first data and the second data. The modules are designed in an independent floating mode. According to the CPCI bus board card provided by the embodiment of the invention, the measurement precision, reliability and anti-interference capability of the board card are improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a compact peripheral interconnection bus board. Background technique [0002] With the advancement of science and technology, test equipment began to develop in the direction of miniaturization and specialization. Compact Peripheral Component Interconnect (CPCI for short) bus products have the advantages of fast speed, small size, high test accuracy, modularization, etc., and are recognized as one of the most promising buses. CPCI bus is widely used in aerospace testing and industrial automation testing and other fields. Solenoid valves are the basic components in aerospace equipment, and the ground test equipment should be able to quickly, accurately and highly reliably test and measure the basic characteristics of the solenoid valves of the single machine under test. The existing compact peripheral interconnection bus boards used for testing the basic charac...
