Claims

1. A PRT-based vehicle scheduling method, comprising:

2. The PRT-based vehicle dispatching method according to claim 1, wherein the extracting train information corresponding to the station according to the station ID comprises:

3. The PRT-based vehicle scheduling method of claim 2, wherein the train information further comprises: train position data;

4. The PRT-based vehicle scheduling method of claim 3, further comprising:

the response station unit sends out a second empty vehicle dispatching request based on the in-station passenger state, wherein the second empty vehicle dispatching request comprises: station ID and number of vehicle positions to be dispatched; the number of the parking spaces to be dispatched is larger than the number of the vacant parking spaces in the station;

extracting train information corresponding to the station according to the station ID, traversing the train information, calculating the number of trains with dispatching states of currently going to the station, calculating the difference value m between the number of the train to be dispatched and the number of the trains, and dispatching m dispatching states of empty trains with the current going to a parking lot and/or stopped in the parking lot to the station based on the train information.

5. The PRT-based vehicle dispatching method of any of claims 1-4, further comprising:

6. The PRT-based vehicle scheduling method of claim 5, wherein the performing of the parking space scheduling based on the passenger carrying status of the train that is currently about to enter the station and the passenger carrying status of the train that is currently stopped at the station comprises:

when the passenger carrying state of the train which is about to enter the station is passenger carrying, judging whether a no-load train exists or not based on the passenger carrying state of the train which is stopped at the station, if so, acquiring parking lot information, dispatching the no-load train to a target parking lot based on the parking lot information, and dispatching the train which is about to enter the station to a parking space corresponding to the no-load train; if not, waiting for allocating parking spaces for the train which is about to enter the station at present in the station waiting area;

7. An electronic device, comprising a processor, a network interface, and a memory, the processor, the network interface, and the memory being interconnected, wherein the memory is configured to store a computer program comprising program instructions, the processor being configured to invoke the program instructions to perform the PRT-based vehicle scheduling method of any one of claims 1-6.

8. A PRT-based vehicle dispatch system, comprising:

the electronic device is used for responding to the first empty vehicle dispatching request and extracting train information corresponding to the station according to the station ID, and the train information comprises: a scheduling state; traversing the train information, calculating the number of trains of which the dispatching state is currently going to the station, judging whether the number of the trains exceeds the number of the vacant stations of the station, and if so, stopping the vacant train dispatching; if not, calculating the difference value n between the number of the vacant trains at the station and the number of the trains, and scheduling n empty trains which are currently going to the storage yard and/or stopped at the storage yard to the station in a scheduling state.

9. The PRT-based vehicle dispatching system of claim 8, wherein the station unit is further configured to monitor the status of passengers in the station, and when it is monitored that more than a number of passengers are waiting in the station, send a second empty dispatch request to the electronic device, the second dispatch request comprising: station ID and number of vehicle positions to be dispatched; the number of the parking spaces to be scheduled is larger than the number of the vacant parking spaces in the station;

10. The PRT-based vehicle dispatch system of claim 8 or 9, wherein the system further comprises: the parking lot unit is used for storing the parking lot,

the station unit is further configured to monitor a train close to a station range, and when the train which is about to enter the station at present is monitored, send an inbound scheduling request to the electronic device, where the inbound scheduling request includes: station ID;

the electronic device is further configured to obtain train information of a train that is about to enter a station currently based on the inbound dispatching request, where the train information includes: scheduling state, passenger carrying state; judging whether the dispatching state is that the station is moving to, if not, stopping the station entering dispatching;
