Abstract

The invention discloses a rubber wheel guide rail electric vehicle control method based on super capacitor power supply and a pantograph-catenary dual-power supply system, and relates to the field of control of rubber wheel guide rail electric vehicles. According to the control method, a software algorithm and hardware signal collection are used for completing automatic pantograph rising and falling and charging and discharging of the rail tramcar in and out of the station, and according to parameters such as a detection leading mark signal, a pantograph net voltage signal, a pantograph rising signal, a pantograph falling signal, a brake maintaining signal and a vehicle speed signal, charging or discharging is judged through software; automatic charging and discharging of the guide rail electric vehicle in a station entering-and-leaving process are realized; in the whole working process, high-voltage electricity does not need to be switched in the whole process of the charging pile, a guide mark system is arranged at a certain distance from a platform, and the working process is divided into five stages according to the charging and discharging process and the arrival state of the rubber wheel guide rail electric car. On the premise of guaranteeing effective charging of the vehicle, the stop time of the vehicle on the platform can be shortened, the cruising ability of the vehicle and the experience of passengers can be improved, the pressure of a driver is relieved, and safety is guaranteed.

Description

technical field

[0001] The invention relates to the control field of rubber-tyred guide rail cars, in particular to a control method for rubber-tyred guide rail cars based on a supercapacitor power supply and a pantograph-catenary dual power supply system. Background technique

[0002] With the development of society, the problems of traffic congestion and environmental pollution in urban areas are becoming more and more serious. The subway has become the best choice for urban rail transit. However, due to the long construction period, high cost, and great influence of the geological environment, the rubber-tyred guide rail tram with a short construction period, shared road rights, and strong climbing ability has become an urban rail transit. A better choice. At present, most of the rubber-tyred guide rail cars use DC750V power supply, resulting in high construction costs and electromagnetic pollution, and has certain limitations; some rubber-tyred guide rail cars use tracti...
