Abstract

The invention relates to a wireless isolation serial communication interface test system having voltage detection, and belongs to the technical field of an electrical communication interface test. The test system includes a data processing and displaying terminal, a test connector, and a wireless communication assembly connecting the data processing and displaying terminal and the test connector. The test connector is formed by a probe, a signal conditioning circuit, an AD sampling circuit, a local measuring algorithm, a serial port communication interface circuit, a anti-over-current driving circuit, a relay, and a data transceiver and test protocol. The over-voltage and over-current are avoided by employing the voltage detection. The wireless isolation realizes the separation of the test connector and terminals for signal detection and communication connection. The volume of the test connector decreases. The demand of the terminal electrical properties is reduced, and the on-site operation is convenient.

Description

technical field

[0001] The invention relates to a wireless isolation serial communication interface testing system with voltage detection, which belongs to the technical field of electrical communication interface testing. Background technique

[0002] Electrical testing tools are necessary devices for the research and development of electrical equipment, as well as related product production testing and on-site repair and maintenance. There are a large number of communication interfaces between electrical equipment components, and testing tools for electrical equipment communication interfaces are also very important. Serial communication interfaces such as CAN bus or 485 bus interface have only two signal lines because of their small number, so they are widely used in electrical equipment and become an important channel for equipment function testing and inspection. However, the installation locations of the equipment are different, and the on-site detection lines often h...
