Problems solved by technology

However, this method is a segmented table lookup that cannot obtain the optimal solution, and has disadvantages such as poor autonomy.
Moreover, neither of the above two methods can be applied to the battlefield environment to solve the problem of evaluating the health status of vehicles

Embodiment 1

[0076] This embodiment provides a path planning method under field conditions based on health status, such as figure 1 shown, including the following steps:

[0077] S001. Obtain the attribute value O of the vehicle i , i=1,2,...,n, constitute the attribute set O={O 1 ,O 2 ,...,O n}, and the attribute value O i Corresponding health ability factor value f i ;

[0078] S002. According to the attribute value O i and the health ability factor value f i , using a comprehensive weighted method to evaluate the health capacity status of the vehicle to obtain the health capacity evaluation grade;

[0079] Preferably, step S002 specifically includes the following steps:

[0080] S21. Obtaining the attribute set O of group p k , k=1,2,..., the importance relationship between any two elements in p;

[0081] Preferably, p groups of attribute sets O k The relationship between the importance of any two elements in can be given by experts in the field, can also be summarized by re...

Embodiment 2

[0149] This embodiment provides a path planning system under field conditions based on the health state, which can be used to implement the path planning method under the field conditions based on the state of health in the above-mentioned embodiment 1, such as Figure 6 shown, including:

[0150] Vehicle attribute value and health ability factor value acquisition unit 1, used to acquire the attribute value Oi of the vehicle, i=1,2,...,n, and form the attribute set O={O 1 ,O 2 ,...,O n}, and the attribute value O i Corresponding health ability factor value f i ;

[0151] A map acquisition unit 2, configured to acquire geographic information of the area to be routed;

[0152] Health ability evaluation unit 3, used for according to attribute value O i and the health ability factor value f i , using a comprehensive weighted method to evaluate the health capacity status of the vehicle to obtain the health capacity evaluation grade;

[0153] The route planning unit 4 is use...

Abstract

The invention discloses a path planning method and system under field conditions based on a health state, and relates to the technical field of artificial intelligence, including acquiring vehicle attribute values ​​and corresponding health ability factor values; The state is evaluated to obtain the health ability evaluation level; when the health ability evaluation level is above the preset evaluation level, the start point coordinates, end point coordinates, and the detour area boundary within a certain range around the straight line between the start point and the end point on the map are obtained and type; respectively expand each detour area boundary as a whole to the detour area safety distance corresponding to its type; each detour boundary on the straight line between the starting point and the end point is respectively expanded to a vehicle safety distance as a whole; Intelligently determine the detour route according to the safety distance of the detour area and the vehicle safety distance, and obtain the vehicle driving route. The invention improves task effectiveness and has the advantages of high autonomy, fast and flexible.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a method and system for path planning under field conditions based on health status. Background technique [0002] The battlefield environment is changing rapidly. Vehicles not only need to be paid attention to their health status at all times. The health status generally includes personnel status, equipment status, remaining fuel status, and material status. Obstacles that need to be bypassed in the driving path, such as prohibited areas, can be used to plan timely obstacle avoidance routes. Only when the above two conditions are satisfied, as a battlefield application, can the vehicle meet the needs of the battlefield after arriving at the destination, otherwise, the vehicle cannot meet the needs of the battlefield because the vehicle does not meet the health status, or the obstacle avoidance cannot meet the needs of the battlefield. Effective in real time and ...
