Problems solved by technology
The commonly used judging equipment for cable continuity in the prior art is mainly to detect after a wired loop is formed by an external cable, so that a very long transmission line needs to be connected during the judging process, especially for a cable with a long distance between both ends. The cables to be tested often require a large number of transfer cables, which is not only costly but also the entire test process is very heavy, and it is difficult to meet the requirements of automation, miniaturization and non-disassembly testing
In addition, the traditional method not only increases the cost of human resources in the testing process but also is inefficient, and cannot meet the needs of cable test automation

Embodiment Construction
[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] Through the application of the wireless transmission technology, the present invention develops a cable on-off judging device carrying a wireless radio frequency module. The main function of this multi-core cable on-off determination device is to receive the current test wiring information sent by the cable on-off detection device through the wireless radio frequency module, and then perform level scanning on all interfaces of the cable to be tested to analyze whether each port receives The excitation level sent by the detection device is compared with the previously obtained current test wiring information for judgment, and then the judgment result is sent to the on-off detection device that provides the excitation signal at the other end of the cable until all tests are completed. Through the application of wireless transmission techn...

The invention relates to a multi-core cable on-off determining device based on wireless transmission technology and a method thereof. The determining device comprises a housing assembly. A circuit board assembly is fixedly arranged in the housing assembly. The circuit board assembly is connected with a power interface through the switch. The circuit board assembly is further connected with an indicating lamp, an antenna and a switching connector. The switching connector is used for connecting with a to-be-tested cable. The antenna is used for receiving wiring information, which is transmittedby the testing device at the other end of the to-be-tested cable, of a current excited tested wire core of the tested cable, and transmits an on-off determining result of the to-be-tested able to thetesting device. The circuit board assembly is used for making the antenna receive wiring information of the to-be-tested cable, tests the levels of all wire cores of the to-be-tested cable, performs comparison with the received tested wire core information, and further determines the on-off condition of the wire core. The device and the method improve determining accuracy and automation degree andfurthermore reduce human resource cost in a testing process.
Description
technical field [0001] The invention relates to the technical field of cable testing instruments, in particular to a multi-core cable on-off judging device and method based on wireless transmission technology. Background technique [0002] At present, various products such as airplanes and automobiles require a large number of transmission lines to ensure the normal operation of the system, and the reliability of transmission lines is crucial to the safety of the entire system. The commonly used judging equipment for cable continuity in the prior art is mainly to detect after a wired loop is formed by an external cable, so that a very long transmission line needs to be connected during the judging process, especially for a cable with a long distance between both ends. The cables to be tested often require a large number of transfer cables, which is not only costly but also the entire test process is very heavy, and it is difficult to meet the requirements of automation, mini...
