In this embodiment, the manifest updating unit is further configured to cancel the current service and update the end time of the piece of service data if the service is interrupted while waiting for executing the service.
Example 2: with reference to fig. 1 and 2, for a clearer illustration of the solution of the invention, based on example 1, we further describe the following:
queuing latency with respect to step (22) of the present invention: for a service, the queuing time of the service is provided by a corresponding service area, specifically, for example, the service is a charging service, the service area can be pre-installed with a public charging station queuing time estimation system, and the queuing time is estimated according to the number of current service vehicles, the waiting number, the service duration of the service vehicles and the like. For example, the service is a car washing service, the service area can be provided with a corresponding service queuing time estimation system in advance, and the queuing time of the service is output.
Regarding the service duration of step (22) of the present invention: for one service, the service duration can be preset, the owner inputs the setting according to the requirement, or the average duration of the service according to the specific content. For example, in the car washing service, the average duration of the service is set to 20 minutes, in the vehicle maintenance service, the average duration of the service is set to 30 minutes, and in the charging service, the charging duration can be calculated according to the remaining capacity of the vehicle.
Ordering of available services with respect to step (3) of the present invention: this ordering is prior art and one way is given here, but is not limited to this in practice.
The sorting mode is as follows: the available services selected by the vehicle owner are ordered first according to the sequence of the expected ending time, and then calibrated, for example:
(1) The owner selects 3 services in total: car washing service, overhaul service and charging service.
(2) The car washing service does not need queuing and has a service duration of 20 minutes, so the service end time=0+20 minutes=20 minutes is expected, the maintenance service needs queuing for 20 minutes and has a service duration of 30 minutes, the service end time=20 minutes+30 minutes=50 minutes is expected, the charging service does not need waiting, but the service duration is about 2 hours according to the residual capacity of the car.
(3) Sequencing: sequencing according to the sequence of the expected ending time to obtain the following sequence: car washing service, overhaul service and charging service.
(4) Calibration to get the start time and end time of each available service. The car washing service does not need to wait, the service time is 20 minutes, after the car washing service is finished, the queuing time of the maintenance service is just reached, the car washing service can be directly maintained, the total maintenance service needs 30 minutes, two services are completed for about 50 minutes, the charging service does not need to wait at present, the charging time is 2 hours, and three services are completed and are expected to be 2 hours and 50 minutes. At the current time T When (when) For example, we can get an initial service list as shown in table 1:
table 1: initial service list
In practice, vehicles cannot move instantaneously from one service area to another directly, and require time to dispatch. For example, when a first service is performed, a vehicle needs to be dispatched from a parking lot entrance to a service area of the service, and before the first service ends and a second service starts, a vehicle needs to be dispatched from a service area of the first service to a service area of the second service. Each time of scheduling has a starting time point, which is called scheduling time, each time of scheduling has a period of time, the values of the preset scheduling time periods T1 and T1 are set according to the size of a parking lot, for the convenience of statistics, a period of scheduling time period T1 is added before each service starts, and a more reasonable optimized service list can be obtained by combining with the table 1, and the optimized service list is shown in the table 2 on the assumption that the scheduling time is 10 minutes.
Table 2: optimizing a list of services
Regarding service confirmation in step (4):
assuming that the total time taken by step (3) is 200 minutes, howeverThe estimated parking time period T of the AVP vehicle Pre-preparation For 2 hours = 120 minutes, then total time consumption > T Pre-preparation Confirming by the vehicle owner that the available service is reduced or that the selected available service is determined via step (41);
if the owner does require these services, then a confirmation is made that the AVP vehicle is predicted to be parked for a period of time T Pre-preparation 200 minutes is reached, if the main service is reduced, then it is reduced as required, and if the charging service is reduced, then the total consumption becomes 70 minutes, less than T Pre-preparation The estimated parking time period T of the AVP vehicle Pre-preparation The time period was constant and was still 2 hours.
Suppose that the owner eventually reserves the available service as 2: car washing service and charging service. Assuming that the current time is 14:00 pm, we output the ranking mode P with the shortest time consumption and the total time consumption T corresponding to P Total (S) ；
1. Car washing service, scheduling time 14:00, starting time 14:10 and ending time 14:30;
2. charging service, scheduling time 14:30, start time 14:40, end time 16:40;
3. total time consuming: 2 hours and 40 minutes.
Since the total time is longer than the estimated parking time period T Pre-preparation 2 hours, so update T Pre-preparation For 2 hours 40 minutes.
Regarding step (5): storing the finally reserved available service ordering mode P in a to-be-serviced list, and table 3:
table 3: to-be-serviced inventory of AVP vehicles
The parking lot management end only needs to schedule the vehicles to the corresponding areas according to the to-be-serviced list. Assuming in step (4) that the owner does not select any available services, the list of to-be-serviced is empty.
Regarding step (6), the departure instruction sent by the vehicle owner to the vehicle-mounted system has the highest priority, if the departure instruction is received in the processing list to be serviced, the current service is completed, and otherwise, the current service is carried out according to the list to be serviced. This step consists mainly in updating the list of AVP vehicles to be serviced. Specific updating methods are given here in connection with table 3 and step (6).
Processing the first piece of service data as in steps (61) - (63):
scheduling vehicles from the entrances to the carwash service areas during 14:00-14:10;
waiting for the corresponding staff to provide the car washing service, and updating the ending time of the first piece of service data according to the time of completing the service. At this time, there may be three cases, completion in advance, completion on time, completion postponed. In any case, the corresponding end time of the service is updated, and the scheduling time, start time, and end time of each piece of service data are updated.
For example: and if the car washing service is finished 5 minutes in advance, updating the corresponding finishing time of the car washing service to be 14:25, and sequentially advancing the scheduling time, the starting time and the finishing time of the subsequent charging service by 5 minutes. And during the period 14:25-14:35, dispatching the vehicle from the carwash service area to the charging service area.
For another example, due to ingress congestion, the time for dispatching the vehicle from the ingress to the carwash service area is timed out, resulting in a delay of 5 minutes from the vehicle to the carwash service area, a delay of 5 minutes from the carwash service, and a final delay of 10 minutes from the end time of the carwash service, the end time of the updated carwash service is 14:40, and the dispatch time, start time, and end time of the subsequent charging service are sequentially delayed by 10 minutes. And during the period 14:40-14:50, dispatching the vehicle from the carwash service area to the charging service area.
For another example, at 16:00 the owner sends a departure instruction, at which time the car wash service is completed, charging service is being carried out, and the charging service is terminated immediately, and the vehicle is dispatched to the exit. If the car owner sends an departure instruction at 14:20, and car washing service is performed at the moment, and the service cannot be interrupted, waiting for car washing to finish, and dispatching the car to an outlet.
When the vehicle is being washed, or the vehicle is being charged, the service is cancelled immediately, and the cancelled time is taken as the end time of the service, and each piece of follow-up service data is updated.
Regarding step (7), mainly parking scheduling. The purpose is to make the vehicle move to the area closer to the exit when the vehicle possibly leaves the ground, so that the time for the vehicle owner to lift the vehicle is shorter and the speed is faster.
If the vehicle owner selects the service and still receives no departure instruction after the service is completed, calculating departure time difference delta T, or if the vehicle owner does not select any service, directly calculating departure time difference delta T according to the current time, judging whether the vehicle should stop in a long stop area or a departure area according to the departure time difference delta T, and executing corresponding scheduling.
The steps (6) and (7) are all the scheduling and dynamic correction of the AVP vehicle.
Example 3: with reference to fig. 1 to 3, we further perfect this solution on the basis of example 1 and example 2. The embodiment mainly adds linkage service of other AVP vehicles. In the intelligent scheduling method of AVP of the present invention, the step (6) further includes a step (64);
(64) The to-be-serviced list of other AVP vehicles waiting for the service is updated, including a scheduled time, a start time, and an end time for each piece of service data.
In the intelligent scheduling system of AVP of the present invention, the service processing unit further includes a subsequent vehicle updating unit for updating a to-be-serviced list of other AVP vehicles waiting for the service, including a scheduling time, a start time, and an end time of each service data.
