Embodiment 1
[0046] Such as figure 1 As shown, the EMU running part safety monitoring method of the present invention comprises the following steps:
[0047] First, in step S110, the state parameters of each component of the running part of the EMU are detected and collected. In this embodiment, the vibration, pressure, temperature, noise and other types of sensors installed in different parts of the bogie, wheelset, axle box, car body, etc. are used to collect the vibration and pressure of the components of the running part of the EMU. , temperature, noise data, and convert the obtained signal into the form of electrical signal or optical signal. Of course, it is also possible to detect only one or several state parameters among vibration, pressure, temperature and noise according to the specific detection purpose.
[0048] Next, in step S120, conditioning is performed on the collected state parameters, so as to convert the state parameter signals into digital signals that can be used i...
Embodiment 2
[0060] Correspondingly, as figure 2 As shown, the present invention also provides a safety monitoring device for the running part of an EMU, which is used to implement the above safety monitoring method. In this example,
[0061] The device includes: a collection module 10 , a conditioning module 20 , a preprocessing module 30 , a failure analysis module 40 , an output module 50 , a storage module 60 and a power supply 70 . in:
[0062] The acquisition module 10 is used to detect and collect the state parameters of each component of the running part of the EMU. In this embodiment, the state parameters include at least one of vibration, pressure, temperature, and noise.
[0063] The conditioning module 20, which is connected to the acquisition module 10, is used to condition the collected state parameters, so as to convert the state parameters into digital signals that can be used for corresponding calculation models; in this embodiment, the conditioning module 20 It may in...

Abstract
The invention discloses a method and device for safety monitoring of the running part of a train set. The method comprises: detecting and collecting state parameters of parts of the running part of a train set. The state parameters include at least one of vibration, pressure, temperature and noise; Adjust the collected state parameters to convert the state parameters into digital signals that can be used in the corresponding calculation model; substitute the digital signal into the corresponding calculation model for preprocessing calculation to generate calculation results; perform fault synthesis based on digital signals and calculation results Analyze and obtain the fault diagnosis results of the train; output calculation results and fault diagnosis results. Through the comprehensive safety monitoring of the running part of the EMU, the present invention can detect hidden troubles and abnormal trends that affect the driving safety in advance, and timely perform pre-alarms, effectively ensuring the running safety of high-speed trains and reducing running risks.
Description
technical field [0001] The invention belongs to rail transitsafety monitoring technology, and in particular relates to a safety monitoring method and device applicable to the running part of a high-speed train multiple unit. Background technique [0002] With the continuous development of high-speed rail construction, train operation safety monitoring has become an important technology to ensure the safe operation of high-speed rail. At present, there are many kinds of train detection equipment equipped with various types of EMUs in China, and the functions are single. Due to the use of different technology platforms, data sharing and intercommunication cannot be realized. disadvantages. [0003] Therefore, there is an urgent need for a new method and device for safety monitoring of running parts of EMUs that can solve the above problems. Contents of the invention [0004] In view of the above problems, the present invention proposes a safety monitoring method and devic...
