Embodiment 1

[0032] Embodiment 1 provides a train fault recording device. Such as figure 1 As shown, the train fault recording device 100 includes a DEVICENET data collector 101 , a DEVICENET board 102 and a CPU (Central Processing Unit, central processing unit) board 103 .

[0033] Wherein, DEVICENET data collector 101 is used for collecting the real-time monitoring data of train, and this real-time monitoring data is sent to DEVICENET board card 102; DEVICENET board card 102 is used for receiving the real-time monitoring data that DEVICENET data collector 101 sends and sends to CPU board The card 103 sends real-time monitoring data; the CPU board 103 includes an Ethernet port 104 for receiving and storing the real-time monitoring data, and calling the real-time monitoring data and sending the real-time monitoring data to the client through the Ethernet port 104 .

[0034] Specifically, the real-time monitoring data is mainly the train operation status collected in real time, such as the...

Embodiment 2

[0040] The second embodiment further explains in detail the CPU board in the train fault recording device of the first embodiment, and other structures are consistent with the above-mentioned embodiment, and will not be repeated here.

[0041] Such as figure 2 As shown, the CPU board 103 in the train fault recording device 100 of this embodiment also includes a 32-bit microprocessor 301 and a memory 302 .

[0042]Specifically, the 32-bit microprocessor 301 is used to receive real-time monitoring data and process the real-time monitoring data, and send the processed real-time monitoring data to the memory 302; the memory 302 is used to receive and store the data sent by the 32-bit microprocessor 301 The processed real-time monitoring data.

[0043] In this way, when the user needs to read the stored historical real-time monitoring data from the memory 302 , it can be directly read from the memory 302 through the Ethernet port 104 . The faulty train can be analyzed through th...

Embodiment 3

[0046] The third embodiment provides a train failure recording method, such as image 3 As shown, it is a schematic flow chart of the train fault recording method in the third embodiment. The train failure recording method can be executed by the train failure recording device of Embodiment 1 and Embodiment 2.

[0047] Step 301, the DEVICENET data collector collects real-time monitoring data of the train, and sends the real-time monitoring data to the DEVICENET board.

[0048] Step 302, the DEVICENET board receives the real-time monitoring data sent by the DEVICENET data collector and sends the real-time monitoring data to the CPU board.

[0049] Step 303, the CPU board receives and stores real-time monitoring data.

[0050] Step 304, the CPU board retrieves the real-time monitoring data and sends the real-time monitoring data to the client through the Ethernet port on the CPU board.

[0051] According to the train fault recording method of the present embodiment 3, the real...

Abstract

The invention discloses a train fault recording device and a method. The train fault recording device comprises a DEVICENET data acquisition unit, a DEVICENET board card and a central processing unit (CPU) board card. The DEVICENET data acquisition unit is used for collecting real-time monitoring data of a train and transmitting the real-time monitoring data to the DEVICENET board card. The DEVICENET board card is used for receiving the real-time monitoring data sent by the DEVICENET data acquisition unit and sending the real-time monitoring data to the CPU board card. The CPU board card comprises an Ethernet port and is used for receiving and storing the real-time monitoring data, taking the real-time monitoring data and sending the real-time monitoring data to a user side through the Ethernet port when users needs the real-time monitoring data. According to the train fault recording device and the method, the users can analyze the traveling conditions of the train according to the real-time monitoring data stored on the CPU board card to prevent a fault from happening again, so the reliability and safety of train operation can be enhanced.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicle communication, in particular to a train fault recording device and method. Background technique [0002] In recent years, with the rapid development of the railway industry, fieldbus has become more and more widely used due to its advantages of high reliability, low cost and low failure rate. [0003] In the prior art, the bus commonly used by rail transit vehicles is based on DEVICENET for communication. The DEVICENET bus has the advantages of openness, low price, reliability and high efficiency, and is especially suitable for the bottom-level control of industrial sites with high real-time requirements. With the increasingly complex structure and equipment of trains and the continuous improvement of speed, the reliability of train operation is required to be high. [0004] But in the prior art, when the train breaks down, it can only be judged by experience, which will waste a lot...
