Embodiment 2

[0036] Such as figure 2 Shown: the switching value acquisition module is used to collect the switching value signal of the vehicle electrical circuit, such as the switching value of the train direction relay, the main control relay, the door switch relay, and the switch of the train brake relay. The switching value acquisition module can collect multi-channel switching value signals, input 24V DC voltage, set when the input range is 18 ~ 24VDC, the system considers it to be high level, and the monitored equipment is in the working state of power, when the collection is lower than 18VDC When , the system considers it to be low level, and the monitored equipment is in the state of no power work stop. In order to avoid electrical characteristics and harsh working environment and affect the control circuit of the vehicle itself, the acquisition module uses a photocoupler TLP521 to realize an electrical-optical-electrical conversion of the signal, which plays the role of input / out...

Abstract

The invention discloses a railway vehicle online monitoring system. The system comprises a vehicle electrical schematic diagram module for dividing vehicle electrical schematic diagram data into different section diagrams through detection points, a database module for storing the section diagrams in sequence according to the numbers of the section diagrams, a railway vehicle information acquisition module for acquiring data information of the vehicle detection points and uploading the data information to the database module, a data processing and analyzing module for calling the data information to be compared with corresponding preset values and outputting comparison results, and a large-screen display control module for calling the section diagrams and displaying the section diagrams inreal time according to the numbers of the section diagrams through a circuit diagram real-time display module, wherein at least one detection point is arranged on each section diagram. According to the design, maintenance personnel can know the occurrence of a fault and a circuit state after the fault occurs in first time; and rapid response and rapid disposal are realized.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to an online monitoring system for rail vehicles. Background technique [0002] At present, rail transit vehicles use train communication network control technology to realize the operation control and fault diagnosis of rail transit vehicle equipment. Vehicle fault information can only be queried and analyzed by manually downloading data after the train is out of service. If a train breaks down during operation, the driver reports to the line controller through the on-board station, and the line control then notifies the inspection and adjustment. The inspection and adjustment will analyze and judge according to the fault phenomenon or fault code fed back by the driver, and take corresponding measures. Its disadvantages are: the information is fed back through the driver's expression, there will be errors in the accuracy of the information (poor accuracy) and the infor...
