The system processing unit is a DSP; and the man-machine interaction unit comprises a 4G Android system intelligent module, a liquid crystal screen and keys.

Description

technical field [0001] The invention relates to track testing equipment, in particular to a handheld track circuit intelligent testing terminal. Background technique [0002] With the rapid development of my country's railway industry, the country has higher and higher requirements for the safety of rail transit and the high-efficiency detection of track circuits. At present, the track circuit testing products on the market have single functions, maintenance personnel need to carry multiple testing equipment for maintenance operations at the same time, and different equipment cannot share data, and maintenance personnel need to manually sort out data afterwards to analyze fault data, often missing the first Time to troubleshoot for a while. In the past, the track circuit testing equipment needed to manually report the fault information when the circuit fault was detected, which not only increased the workload of the staff to record the fault information, but also delayed th...
