Detection device used by monitoring and recording plug-ins

Abstract

The invention provides a detection device used by monitoring and recording plug-ins, which comprises multiple monitoring and recording plug-ins and a cabinet, wherein each monitoring and recording plug-in is provided with a plug connector; the cabinet comprises multiple cases, multiple socket connectors and a power supply module; each case can accommodate one part of the multiple monitoring and recording plug-ins; the multiple socket connectors are corresponding to each monitoring and recording plug-in; and the power supply module is used for providing power for the multiple monitoring and recording plug-ins to meet simultaneous detection on the multiple monitoring and recording plug-ins.

Description

technical field [0001] The invention relates to the field of train operation monitoring, in particular to a detection device used for monitoring and recording plug-ins. Background technique [0002] LKJ2000 train operation monitoring device is an important guarantee for the safe operation of railway locomotives. The LKJ2000 train operation monitoring device adopts MC68332 32-bit computer microprocessor technology, dual-computer hot standby redundancy technology and digital signal processing technology to ensure the safety control of railway locomotives. The monitoring and recording plug-in is the core of the LKJ2000 train operation monitoring device, and the normal operation of the monitoring and recording plug-in is the decisive factor to ensure the normal operation of the LKJ2000 train operation monitoring device. [0003] The monitoring and recording plug-in is responsible for monitoring whether the railway locomotive is running safely, and completing the recording and s...

Problems solved by technology

[0008] 3. The detection items in the detection plan do not cover all functions of the product. Currently, only the detection of the internal chip function, communication function and part of the output signal of the monitoring and recording plug-in is carried out, and the detection of the TPU channel signal is lacking;

[0009] 4. The detection of the QSPI synchronous communication function is not comprehensive. During the detection, the master-slave relationship switching can only be realized by exchanging the positions of the tested and accompanying monitoring and recording plug-ins;

[0010] 5. It is impossible to judge whether the monitoring and recording plug-in is reset during the detection process, and there is no reset status indicator
