specific Embodiment approach 1

[0033] Specific implementation mode one: combine figure 1 Describe the present embodiment, the automatic speed regulation system of the railway vehicle based on the genetic algorithm of the present embodiment, it comprises weighing equipment 1, the first speed measuring equipment 2, control box 3, weighing computer 4, control computer 5, drive power supply 6 And deceleration device 7; the first speed measuring device 2 is made up of N first speed measuring sensors, and deceleration device 7 is made up of N decelerating devices, wherein N is a positive integer, and N is the number of strands;

[0034] The weighing device 1 is used to obtain the total weight signal of the vehicle, and send the total weight signal to the control box 3; the vehicle includes a plurality of compartments connected together;

[0035] The first speed measuring device 2 is used to obtain the speed signal before the speed regulation of the vehicle, and send the speed signal to the control box 3;

[003...

specific Embodiment approach 2

[0042] Specific implementation mode two: combination figure 2 To illustrate this embodiment, the difference from Embodiment 1 is that the automatic speed regulation system for railway vehicles based on genetic algorithm in this embodiment also includes a second speed measuring device 8, and the second speed measuring device 8 is composed of N second speed sensor, and the deceleration device 7 is composed of a plurality of on-site hydraulic deceleration jacks;

[0043] The second speed measuring device 8 is used to obtain a speed signal after speed regulation of the vehicle, and send the speed signal after speed regulation to the control box 3;

[0044] The control box 3 is also used for analog-to-digital conversion of the received speed signal after speed regulation, and sends the converted speed signal after speed regulation to the weighing computer 4; it is also used for on-site hydraulic deceleration The number of jacks to be started is sent to the control computer 5; it ...

specific Embodiment approach 3

[0049] Specific implementation mode three: combination figure 2 Describe this embodiment, and embodiment one or two are different, the automatic speed regulation system of the railway vehicle based on genetic algorithm of this embodiment, it also includes manual console 9;

[0050] The manual console 9 is used to output a manual control signal to the control computer 5 through manual manual control;

[0051] The control computer 5 is also used to output the control driving quantity V to the control box 3 according to the received manual control signal.

[0052] In this embodiment, the manual console 9 outputs a manual control signal to the control box 3, and then the control box 3 outputs a power drive signal to the drive power supply 6, and then the drive power supply 6 controls the operation of the speed reduction device 7 according to the received power drive signal, thereby Realized the manual speed control of the vehicle.

Abstract

The invention discloses an automatic speed regulation system of railway vehicles based on a genetic algorithm and a speed regulation method thereof, relating to the filed of rail way automatic speed regulation, and solving the problems of poor and inaccurate regulation results when railway automatic speed regulation equipment and a method which are constructed by applying the 'accuranvy control' theory. The automatic speed regulation system comprises weight measurement equipment, first speed measurement equipment, a control box, a weight measurement computer, a control computer, a drive power and a reduction gear. When a vehicle humps down from a hump, the weight measurement computer calculates out the weight of each coach and the number of the coaches through the weight measurement equipment and the first speed measurement equipment, the information is transmitted to the control computer, and then the control computer combines the speed measured by the speed measurement equipment on the basis of the information, controls the speed regulation equipment through the drive power, and the wheels of the vehicle is braked by the speed regulation equipment, thus achieving the purpose of regulating the speed of the vehicle. The invention can be applied to the field of railway vehicle speed regulation.

Description

technical field [0001] The invention relates to an automatic speed regulation system and a speed regulation method of a railway vehicle. Background technique [0002] The railway is the main artery of the national economy, and the automatic speed regulation system of railway vehicles is one of the important means to realize the automation of railway marshalling yards. It mainly solves the problem of speed regulation when dismantling working vehicles in the railway freight hump marshalling yard, especially the small and medium marshalling yard. Since the 1990s, the system has achieved good speed regulation results in many places. The system has a very high degree of automation and completely replaces outdated manual operations such as iron shoes and hand brakes. At the same time, it greatly improves the efficiency of freight transportation, thereby improving economic and social benefits. [0003] The process of rolling and releasing the humped vehicle is a dynamic process w...
