Technical Field

The invention belongs to the technical field of trolley buses, and particularly relates to an automatic branching control method and device for a trolley bus.

Background

The trolley bus has the advantage of zero emission and is widely applied to various big cities.

When the trolley bus route is divided into two routes by one route, the number of wire net contact wires is changed from 2 to 4, so that the wire dividers are installed on the wire net. Typically, an electrodynamic splitter is most commonly used.

The wire-separating action principle of the electric wire separator is as follows: when the electric car needs to be separated into lines, a driver needs to step on an accelerator pedal in advance, the line net passes through current, the relay of the line separator is electrified to act, and the guide tongue of the line separator is pulled to change into a line separating state. After the wire-dividing operation, it is pulled back to the straight state by the return spring. On the contrary, when the electric car passes through the straight line, the driver only needs to keep the car sliding, so that the electric car passes through the deconcentrator by means of inertia, and when the relay is not electrified, the deconcentrator tongue guide device is in a straight-line state.

In practical application, the traditional trolley bus adopts a 'open-word car swinging' operation mode: when the trolley pole of the trolley bus runs through the deconcentrator, the trolley pole is stepped on the electric door, namely, the trolley door is stepped on, and when the trolley pole runs through the deconcentrator with electricity, the deconcentrator guide tongue can be pulled, and the vehicle is ready to turn. Due to the structural limitation of the deconcentrator, the current trolley bus generally requires that the speed of the trolley bus is not more than 10km/h when the trolley bus passes through the deconcentrator, needs to run a small section at a low speed, and then needs to rapidly start when the trolley bus is separated from the deconcentrator. The phenomenon is a common phenomenon of opening characters of the electric car, the sudden brake is violent, the requirement on a driver is high, rich experience is required, the comfort of passengers is poor, and the risk of branching failure is high.

In part of special markets, branching control buttons are customized on the trolley bus to operate, the branching buttons are pressed before the position of the branching device, the speed of the vehicle is controlled to drive through the position of the branching device, however, the mode only simplifies the operation requirements of an accelerator pedal, the requirements on the operation experience of a driver are not improved, the riding comfort during branching is still poor, and the branching success rate cannot be guaranteed. Especially, with the popularization of the double-source trolley bus with huge adaptability advantage, due to the decoupling of the wire network power supply and the vehicle power, the change of the depth of an accelerator pedal and the current of the wire network can have larger difference, so that more uncertain states exist in the existing wire-separating operation mode, the failure rate of wire separation is high when a new trolley is on the wire, and further the off-grid and pole dropping are caused, even the collector head is damaged, and the operation effect and the customer experience of the trolley bus are influenced.

Moreover, when the branching of the trolley bus is needed, a driver does not need to step on an electric door, and only needs to control the vehicle speed to the branching speed through an accelerator pedal or a brake pedal, so that the working intensity of the driver is reduced, and the requirement on the experience of the driver is low; the riding comfort is improved, and the client experience of the trolley bus is guaranteed.

Detailed Description

The method of the invention is applied to a trolley bus as shown in figure 1.

As shown in figure 1, the high-voltage power circuit comprises a current collector, the current collector is connected with a network contact wire and outputs the current collector to a power conversion module (DC/DC module), the output of the power conversion module is connected with a high-voltage power distribution part, the high-voltage power distribution part is simultaneously connected with power batteries, a driving motor controller and other electric equipment, and the driving motor controller is connected with a driving motor in a control mode so as to drive the trackless trolley to run.

In order to implement the method of the present invention, a signal loop is added in fig. 1, the signal loop includes a position determination module for obtaining a distance between a current position of the trolley bus and the deconcentrator, the position determination module is connected with a vehicle controller, and the vehicle controller is respectively connected with a power supply transformation module and a driving motor controller.

The position judging module can adopt positioning modules such as a GPS (global positioning system), a BDNS (brain-based data system) and the like, and the position of the wire divider needs to be calibrated at the moment. When the trolley bus is positioned, the positioning accuracy of the positioning method needs to be higher than 5m, wherein the foundation enhanced positioning system is preferably used for enabling the positioning accuracy to be higher than 1 m.

Of course, the RFID tag positioning technology may also be used, and in this case, the RFID tag needs to be arranged near the splitter, and the receiver needs to be arranged near the trolley bus. In order to ensure the stability of the positioning signals, a multi-point label is arranged near the deconcentrator to assist in judgment so as to improve the accuracy of position identification.

In addition, an image recognition technology can also be adopted, in this case, a striking graphic mark is generally required to be arranged at the position of the deconcentrator, a high-precision day and night camera and an image processor are arranged on the top of the trolley bus, and the camera is used for shooting images to recognize and judge whether the deconcentrator is within a set deconcentration distance.

Besides the three methods and techniques described above, other methods and techniques known in the art may be used, as long as the distance between the trolley bus and the line distributor can be detected.

The working process is as follows:

in the running process of the trolley bus, whether a zero-power pedal is pressed down is judged:

if the zero-power pedal is stepped on, the vehicle can directly slide through.

If the zero-power pedal is not stepped on, the position judgment module collects the relative position of the deconcentrator and the trolley bus, and sends the distance information between the trolley bus and the deconcentrator to the vehicle control unit, and the vehicle control unit judges the distance information:

if the distance between the vehicle power battery and the driving motor is judged to be smaller than the set branching distance, the working states of the vehicle power battery, the driving motor controller and the like are judged, if the vehicle power battery and the driving motor controller work normally, the condition of carrying out wire network charging is met, the whole vehicle controller sends an instruction to the power conversion module, the power conversion module starts to work, the power is adjusted until the branching current of the branching device is met, the relay of the branching device is electrified to act, the guide tongue of the branching device is pulled to change the branching state, the wire network electricity is converted into the electricity for the whole vehicle, and the electricity is supplied to.

At the moment, the driver can complete the automatic branching function only by controlling the vehicle speed to the branching vehicle speed through the accelerator pedal or the brake pedal, and the driver does not need to fiercely reduce or fiercely accelerate, so that the working strength of the driver is reduced, and the comfort is improved. And when the branching device is not needed, the sliding and passing can be realized only by stepping on a zero-power pedal, so that the operation is convenient.

In addition, the method can also be applied to trackless trolleybuses with other electrical configurations. For example, the integrated configuration of the high-voltage power distribution and the driving motor controller forms an integrated controller, so that the connection form of a high-voltage system can be simplified, the integration level of the system is improved, and connection points are reduced; or the power conversion module is directly connected with the power battery system.
