Embodiment 1

[0044] In order to solve the problem of low detection efficiency and waste of human resources in the prior art, which usually manually checks the health status of rail trains, this embodiment provides an operation data collection and transmission system for rail trains. Please refer to figure 1 As shown, it includes a gateway 11 and a plurality of sensor nodes 12 arranged on rail trains, and each sensor node 12 includes: a controller 120, a sensor 121, a wireless transmission module 122, a rechargeable energy storage element 123, and a vibration energy harvester 124 and battery 125, wherein:

[0045] The vibration energy collector 124 is used to convert the mechanical energy generated by the vibration of the wheel axle into electrical energy and transmit it to the rechargeable energy storage element 123 for storage; the controller 120 is used to detect that the voltage of the rechargeable energy storage element 123 is greater than the preset voltage threshold When the recharge...

Embodiment 2

[0062] Based on the rail train running data collection and transmission system provided in the above embodiment, this embodiment provides a collection and transmission method, please refer to Figure 5 shown, including:

[0063] S2: The controller of each sensor node controls the corresponding sensor node to enter a sleep state.

[0064] S4: wake up each sensor node after the preset first wake-up time period arrives.

[0065] The first wake-up time period may be 0.5 hour, of course, may also be 20 minutes, 1 hour, etc. Specifically, the sensor node may be woken up through an RTC alarm event.

[0066]S6: the controller of each sensor node collects the voltage of each rechargeable energy storage element.

[0067] S8: Judging whether the voltage of the rechargeable energy storage element is greater than the preset voltage threshold, if yes, go to S10, otherwise go to S2.

[0068] S10: Determine whether the rail train is running, if so, go to S12, otherwise go to S2.

Abstract

The invention discloses an operation data acquisition and transmission system and method for a rail train, and belongs to the technical field of rail train operation control. Operation data of the rail train is automatically acquired through a plurality of sensor nodes arranged on the rail train and transmitted to a gateway, and no manual participation is required in the whole process, thereby reducing the human resource input for monitoring the operation condition of the rail train; a controller can control corresponding sensor nodes to enter a sleep state when the rail train is in a non-operating state or when the voltage of a rechargeable energy storage element is detected to be less than or equal to a preset voltage threshold, thereby reducing the power consumption of the sensor nodes;in addition, the sensor nodes can also enter the sleep state after completing the transmission of one time of the operation data together, so that the energy-saving mode provides energy guarantee formonitoring the operation condition of the rail train, prolongs the service life of the sensor nodes, and effectively reduces the maintenance cost of the rail train.

Description

technical field [0001] The invention relates to the technical field of rail train operation control, more specifically, to a rail train operation data collection and transmission system and a data collection and transmission method. Background technique [0002] The high-speed trains currently used in my country are generally 8 carriages or 16 carriages, which are widely used in passenger transportation scenarios. Compared with freight trains with hundreds of carriages, high-speed trains are considered short-car scenarios and are used in daily railway transportation scenarios. Also more extensive. With the vigorous development of my country's rail transit industry, the safety of rail transit vehicles has become more and more important. Since health monitoring is an important guarantee for the safe operation of trains, it is necessary to take corresponding measures to realize the fault detection of core components of trains. The traditional low-efficiency manual periodic ins...
