Description

Technical Field

[0001] The utility model relates to the technical field of multi-channel radio frequency relay circuit testing, in particular to an automatic testing device for multi-channel radio frequency relay circuits. Background Technique

[0002] The relay circuit is a new common data exchange network communication protocol that emerged in 1992 and began to develop rapidly in 1994. Relay is an effective data transmission technology that can quickly and inexpensively transmit digital information in one-to-one or one-to-many applications. It can be used for voice and data communications, and can be used for both local area network (LAN) and wide area network (WAN) communications. Each frame relay user will get a dedicated line connected to the frame relay node. For end users, the frame relay network processes data transmission with other users through a channel that often changes and is invisible to users. In the use of relay circuits, a testing device is required for testing.

[0003] After retrieval, the patent with the publication number CN216490519U discloses an automatic testing device for an eight-channel radio frequency relay circuit, including a detection box. A groove is provided in the middle of the lower end of the detection box, and fixing rings are provided at the front and rear ends of the middle of the groove. A circuit board is provided in the middle of the inner side of the detection box, and two openings are equidistantly provided in the lower part of the inner side of the detection box. In this utility model, the power cable to be detected is passed through the fixing ring and the detection ring and fixed, and then the bottom of the detection box and the fixing plate are fixed by sequentially passing connecting bolts through the through holes and threaded holes. Finally, it is fixed to the telegraph pole body through a hoop, improving the accuracy of test data. At the same time, the current detector and voltage detector in the detection box automatically detect and test the line, and then the tested data is transmitted to the signal transmitter through the circuit board, and the test result is fed back to the terminal through the signal transmitter, eliminating the need for manual climbing tests and having high test efficiency.
