Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] According to the background technology, in the test part of the LEU cable detection box, the connecting cables (the length of the cable is between 200m and 4500m) need to be connected for a certain distance during the test, which takes up a lot of space, and is heavy and inconvenient to transfer. In some places where testing is required, and in some test environments there is a large demand for labor, how to quickly detect the test results of the LEU cab...

Abstract

The invention provides a test device and a test system. The test device comprises a communication module used for receiving a first instruction sent by a host computer, a simulation signal output module used for generating a first simulation signal according to the first instruction and sending the first simulation signal to a detection box, and a load and state switching module used for generating the simulation load network according to the first instruction, wherein a first feedback signal is generated by the detection box according to the first simulation signal, after the first simulationsignal is received by the detection box, a first detection signal is generated by the detection box, the first detection signal is further sent to the load and state switching module for detecting the simulation load network, a second feedback signal is generated by the detection box according to the detection result, and the work state of the detection box is detected by the host computer according to the first feedback signal and the second feedback signal. The test device is advantaged in that the work environment of the detection box in the actual application can be simulated, the test result of the detection box can be rapidly detected through simulation signal interaction, and test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of testing LEU cable detection boxes, and more specifically relates to a testing device and a testing system. Background technique [0002] In the transponder system, it is necessary for the LEU cable detection box to detect the cable fault between the surface electronic unit (LEU) and the transponder, wherein the LEU cable detection box is connected between the LEU and the transponder. [0003] The LEU cable detection box has two parts: debugging and testing before leaving the factory. Among them, the debugging part is to start the debugging steps of the LEU cable detection box after confirming that the connection status of each device is normal. Manually input the parameters of the LEU cable detection box on the host computer through the serial port assistant, and send them to the LEU cable detection box device through the serial port. After the writing is completed, the upper computer reads back the wri...
