Description

Technical Field

[0001] This utility model belongs to the field of rail transit signal detection technology, specifically relating to a portable vehicle-mounted signal positioning tester. Background Technology

[0002] Ground transponders are key equipment in rail transit signaling systems, belonging to the category of signal transceivers. They are primarily installed in the middle of subway or railway tracks, communicating wirelessly with the train via electromagnetic induction to transmit data such as track parameters and speed limits to onboard equipment. Applications include train positioning and safety control. This device is activated by an onboard antenna, using magnetic field coupling to acquire energy and transmit pre-stored data, ensuring train operation safety. Therefore, regular testing is crucial. Existing signal detection devices include an extension rod with the transponder fixed at one end. Traditional testing methods require two people: one observing the signal on the train, and the other scanning the beacon under the train by waving the extension rod. This method suffers from low efficiency, low accuracy, and high labor costs. Summary of the Invention
