Problems solved by technology

This method has certain limitations and hysteresis. During the loading process, since the detection equipment is at a fixed station, the center of mass cannot be detected in real time, which affects work efficiency and brings economic losses.
In addition, based on the dynamic weighing of running vehicles based on the ground, it is necessary to establish many monitoring stations along the main railway line, but there is a detection dead zone, and on-board detection cannot be realized; Therefore, the real-time detection of overloading and partial loading of heavy-duty freight trains is of great significance

Embodiment Construction

[0012] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0013] From figure 1 It can be seen that the weight transfer order of the freight train after loading cargo is that the car sits on the lower center plate 3 of the bogie, the center plate 3 transmits the force to the bolster 4, and the bolster 4 transmits the force to the side frame 2 through the spring 5 , the side frame 2 then transmits the force to the axle 6 through the bearing 1, and finally acts on the rail 7. Among them, the bolster 4 is an independent load-bearing component, and there is no possibility of missing force, so the on-board weighing can be realized by indirectly measuring the deformation information of the bolster.

[0014] After modeling and simulation analysis, the stress output at the upper surface between the center plate of the bolster and the side bearing is larger and the linearity is better, so the installation...

Abstract

The invention discloses an on-board weighing method for measuring a freight train based on a bolster. According to the method, an on-board weighing sensor is additionally arranged on the upper surfaceof the bolster in a bogie so as to be used for sensing a strain value generated by the variation in weight of the train body at the surface of the bolster, and the strain value is converted into a corresponding voltage or AD signal. The bottom of a compartment is provided with an on-board intelligent terminal which is used for collecting and processing data of various sensors in real time, and finally the accurate weight is obtained through calibration. The on-board weighing method overcomes defects of the traditional weighing equipment, has the advantages of high efficiency, high accuracy, easy installation and maintenance, low cost, easy function expansion and the like, and is completely suitable for real-time rapid detection for overloading and unbalanced loading of the freight train.

Description

technical field [0001] The invention relates to on-board weighing of freight trains. Background technique [0002] With the development of the economy, the railway transportation industry is advancing towards high speed, heavy load, intelligence and safety, and the railway transportation is also facing many problems in the development process. With the increase of train speed, freight safety is becoming more and more important in the process of railway transportation. The problem of overloading and unbalanced loading of freight trains is an important factor that causes derailment of vehicles and affects the safety of railway traffic. Investment in the field of application continues to increase. [0003] The traditional weighing method is to install track scales in a fixed position, and achieve weighing when the vehicle passes at a low speed or is stationary. This method has certain limitations and hysteresis. During the loading process, since the detection equipment is at...
