A system and method for precise command and dispatch of large-scale security tasks

Abstract

The invention discloses a large-scale guard duty accurate command and dispatching system and a large-scale guard duty accurate command and dispatching method, and belongs to the technical field of intelligent transportation application. Road information conditions are imitated when guard tasks are executed, before the guard tasks are executed, a leader automobile with a vehicle position detection unit runs along a route which needs walking actually for one time, position information confirmed by the vehicle position detection unit in real time serves as a standard position, data correction of an electronic map is not needed, the position information confirmed by the vehicle position detection unit is directly used as vehicle actual position information in a task executing process, when the distance caused by the fact that a vehicle deviates the standard position is too large, the vehicle adjusts a vehicle speed, the imitated standard position is based on evidence, and accuracy is greatly improved.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic command and control, in particular to a system and method for precise command and dispatch of large-scale guard tasks. Background technique [0002] With the rapid development of society, when major cities undertake large-scale international conferences and large-scale events, they often encounter the situation that multiple security convoys depart from different stations and arrive at the same venue at the same time. How to ensure that each guard convoy can arrive at the destination within the specified time and at the specified time interval, and minimize the impact on normal traffic is the goal pursued by the commanders of the guard task convoy. [0003] The existing patent document CN 1581242A discloses an automatic command and dispatch system and operation method for large-scale guard missions. Manually draw the guard route on the electronic map in the form of broken lines, and th...

AI Technical Summary

Problems solved by technology

[0004] (1) In the above technical solution, it is necessary to manually draw the guard mission route on the electronic map in the form of a broken line, store the estimated average speed as the plan information, and obtain the time for the vehicle to pass through each point according to the estimated average speed, so the plan information is all It is estimated, and the command and dispatch based on the estimated plan information cannot guarantee the accuracy

[0005] (2) In the above technical solution, when performing guard tasks, the virtual position stored in the process data table is artificially calculated based on the route, departure time and estimated vehicle speed, which cannot fully meet the actual operation needs of the fleet

[0006] (3) When performing large-scale security tasks, the team needs to arrive at the destination accurately to the second and the time interval between the team and the team is also accurate to the second. According to the above-mentioned technical scheme, the distance between the current position of the team and the estimated virtual position exceeds When the threshold is reached, command it to adjust the vehicle speed. In the actual driving process, the driving speed is different according to different road conditions, and the driving time for the same distance is not necessarily the same. Therefore, the above command and dispatch scheme cannot guarantee the accuracy of the command and dispatch. Accurate to the second

[0007] (4) Using the above-mentioned technical scheme to perform tasks, the security personnel cannot timely obtain the information on whether the guard convoy has arrived at the specified position in accordance with the specified time and is accurate to the second during the process of performing the task, especially at the specified time. When you do not reach the specified position within the time limit, you need to rely on the continuous notification from the commander to know how you need to adjust the speed of the vehicle, and you cannot actively adjust the speed of the vehicle in time to achieve the goal of accuracy to the second

Since there is a certain deviation between the longitude and latitude of the vehicle's driving position on the actual road and the longitude and latitude processed by the road matching algorithm, the data processed by the road matching algorithm is used as the basis for judging whether the vehicle is driving normally, which will cause the actual position data of the vehicle to There is always a certain deviation from the benchmark data, which cannot ensure that the leading vehicle completes the task accurately to the second
