Ropeway carriage speed control method

Abstract

The invention discloses a ropeway carriage speed control method. The method comprises an acceleration control process and a deceleration control process, wherein the acceleration control process comprises the steps of acquiring initial design speed, operation design speed and acceleration time, and controlling acceleration of a ropeway carriage, thereby completing the ropeway carriage acceleration control process; the deceleration control process comprises the steps of acquiring initial design speed, operation design speed, deceleration time and design distance, computing the deceleration distance of the ropeway carriage, and controlling deceleration of the ropeway carriage, thereby completing the ropeway carriage deceleration process. The ropeway carriage speed control method has the advantages that stable acceleration and deceleration of a ropeway carriage can be guaranteed, and impact, vibration and noise of linear acceleration and deceleration are avoided; deceleration points of a carriage can be computed, a sensor is omitted, and thus the cost is lowered; the method can be directly applied to a traditional ropeway control system, and no extra hardware investment is added; all control is performed by soft ware, and the defects of high fault rate and imprecise control of a traditional control method are avoided.

Description

technical field [0001] The invention specifically relates to a speed control method of a cableway carriage. Background technique [0002] Because of its wide application range, the cableway has been widely used in mountainous areas, tourist attractions and other places. Reciprocating cableway is a common form of cableway. It has strong adaptability to natural terrain, especially places with large spans and deep grooves. At the same time, passengers are not affected by climate conditions in the compartment, with strong climbing ability and high running speed. Strong carrying capacity and easy maintenance. Therefore, it has been widely used in tourist places. Reciprocating cableways generally have two steel cables, one is the load cable and the other is the traction cable. The carriage runs on the load-bearing cable, the traction cable is fixedly connected with the carriage, and the traction motor pulls the carriage through the traction cable to perform reciprocating motion...

AI Technical Summary

Problems solved by technology

In the speed control of the cableway car, once the speed of the car is not well controlled, the car will stop running before it enters the station, and the passengers cannot get off safely, or there will be a problem that the speed of the car has not been reduced to stop when it reaches the parking space. As a result, the occurrence of "rushing station" accidents

[0004] At present, the traditional speed setting is achieved through analog components: when analog components are used for speed setting, it is extremely difficult for analog components to realize complex given curves. Even if the speed control of complex curves is realized, It will also lead to extremely complex implementation of analog components; at the same time, the use of hardware circuits composed of complex analog components will significantly reduce hardware reliability and increase the possibility of system failure
