Below content of the present invention is further described:
At first need to set up guard's prediction scheme database, be used to preserve guard's prediction scheme of each fleet, main field comprises: guard duty numbering, date, fleet's departure time and time of arrival, the estimated average speed of a motor vehicle, variance thresholds, preceding guide-car's positioning equipment number, task executor and communication number, transit point etc.
By guard duty input window input guard duty route and corresponding information, parameter.Information such as mission number, date, fleet time of arrival, average speed, variance thresholds, preceding guide-car's positioning equipment number, executor and communication number thereof at first are set, then on electronic chart by the mode of the drawing broken line track route of guard duty that draws, system automatically with the location coordinate information recorded and stored of each transit point (broken line flex point) in database.System is according to route and average speed, time of arrival extrapolating fleet's departure time and data-in storehouse.
To generate a task process tables of data before the operation, be used to write down all guard dutys that current time is being carried out or do not begun as yet to carry out, main field comprises information such as mission number, preceding guide-car's positioning equipment number, task executor, task status, task process prompting.
Open the task process list window, the information that can show current task process data table, i.e. all current execution or still unenforced guard duty comprise information such as mission number, preceding guide-car's positioning equipment number, task executor, task status, task process prompting.It is movable at the same time to note having a plurality of guard dutys.
Task status comprises states such as " finishing ", " in carrying out ", " not beginning as yet ".The task process prompting is the prompting of making at the deviation between current actual advanced positions of this fleet and current planning advanced positions, when for example deviation does not surpass deviation prompting threshold values, points out this fleet " it is normal to advance "; When surpassing deviation prompting threshold values, point out this fleet " speed is slow excessively, and hysteresis d rice please quicken " or " excessive velocities, leading d rice please slow down ".
Go up the Vehicle positioning system of installing by guide-car before the fleet, the locating information of vehicle is sent it back command centre, native system can convert the latitude and longitude information of this vehicle location to the coordinate information on the electronic chart, shows the current actual advanced positions of this guard fleet then on electronic chart.For the fleet of schedule variance, show speed adjustment prompt window on its next door, and show corresponding speed adjustment information above deviation prompting threshold values.
Attention is for the guard fleet of time requirement strictness, its process deviation prompting threshold values should less (as 100 meters), and is not really strict for time requirement, can be big (as 500 meters, 1000 meters etc.).
Adjust the guard fleet of travelling speed for needs, task process information (being the command scheduling instruction) is when being prompted to the commanding, also will send to the guard duty executor immediately automatically by paging station or mobile phone short messages, every blank(ing) instruction sends cycle interval T (for example T=20) second transmission 1 time automatically, thereby has realized the automatic scheduling to guard duty.
The real time modifying of task process tables of data comprises the comparison of fleet's physical location and virtual location, is finished by the automatic command scheduling processing unit of guard duty.The automatic command scheduling processing unit of guard duty per second operation 1 time, its process flow diagram as shown in Figure 1.Its course of work is as follows:
At first search out the guard duty of all time of arrival greater than the current time (represent current do not finish as yet), read i bar task, whether the fleet's departure time according to this task judges less than the current time whether this task begins, be task status=" in carrying out " then, otherwise task status=" not beginning as yet "; For the guard duty of well afoot, calculate the virtual location P of this fleet according to circuit, departure time, the expectation speed of a motor vehicle of guard duty
iConvert the real-time vehicle locating information of this fleet to electronic chart coordinate G
i, then can calculate physical location G
iWith virtual location P
iBetween apart from d, d illustrates then that smaller or equal to variance thresholds fleet advances normally, process prompting=" it is normal to advance "; D illustrates then that greater than variance thresholds fleet's deviation of advancing is excessive, it adjusts the speed of a motor vehicle to need commander, at first need to judge still to be to lag behind in advance by the bias direction discriminant function, and, check the automatic transmitting counter t of dispatch command of this task then according to leading or the prompting of hysteresis generation process " excessive velocities; leading d rice please be slowed down " or " speed is slow excessively, hysteresis d rice; please quicken "
i, t

At first search out the guard duty of all concluding times greater than the current time (represent current do not finish as yet), read i bar task, whether the start time according to this task judges less than the current time whether this task begins, suppose current time 10:04, and this task start time 10:02, then task status=" in carrying out ".
For the guard duty of well afoot, calculate the virtual location P of this fleet of current time according to circuit, departure time, the expectation speed of a motor vehicle of guard duty
i=(1000,1200), the real-time vehicle locating information of this fleet converts the electronic chart coordinate to, can learn the current physical location G of fleet
i, suppose the current physical location G of fleet
i=(800,900) then can calculate physical location and virtual location P
iBetween apart from d=360 rice, d is greater than variance thresholds (200 meters), illustrates that then fleet's deviation of advancing is excessive, it adjusts speed of a motor vehicle to need commander, at first needs to judge still to be to lag behind in advance by the bias direction discriminant function.
Suppose last second virtual location Q
i=(980,1180), G so
i=(800,900) and P
