The invention relates to a cable wireless testing system which comprises an upper control unit and a lower testing unit; the lower testing unit comprises a lower computer the core of which is formed by embedded SOC micro process, as well as a switch control unit, a D / A control unit, an A / D collecting unit, a head end switch control unit, and an AC high voltage, DC high voltage and constant current source generating unit respectively connected with the lower computer. The upper computer and the lower computer are connected by a wireless transmit-receive communication unit; the head end switch control unit and a tail end processor unit are connected by the wireless transmit-receive communication unit; the lower computer gives out a command to the head end switch control unit and receives the processing signal of the tail end processor by the wireless transmit-receive communication unit. When the cable wireless testing system tests different cables and wiring harnesses, only the corresponding adaptive cables needs to be substituted; and the testing applications are broader.
Description
technical field [0001] The invention relates to a cable testing system, in particular to a cable wireless testing system. Background technique [0002] At present, in the modern high-tech environment, the control equipment system with powerful functions, precise control and reliable operation is composed of a large number of electronic components connected by dense cables and wire harnesses. The correctness and reliability of these cables and wire harness connections play an important role in ensuring the reliable operation of the control equipment system. High-speed, accurate, and automatic testing of various electrical indicators of various complex cables and wiring harnesses is a must for manufacturers of control equipment and repair departments at all levels, production, machine debugging, factory inspection, maintenance, overhaul, and processes. An important link is missing. [0003] However, according to statistics, many units such as manufacturers and repair departm...
