Description

一种基于数字孪生的应急警力调度方法及系统An emergency police dispatching method and system based on digital twins 技术领域Technical field
本发明属于公共安全管理技术领域，具体涉及一种基于数字孪生的应急警力调度方法及系统。The invention belongs to the technical field of public safety management, and specifically relates to an emergency police dispatching method and system based on digital twins.
背景技术Background technique
警力由警员、警械、警车等组成的，是维护社会稳定和可持续发展、关乎国家长治久安和人民安居乐业的重要力量。然而随着经济社会的不断高速发展，公安机关的警力布置难以饱和式的覆盖社会的每一个角落，特别是在突发事件发生时，通常难以保证警力的正常高效配置。因此，利用智能化数字化手段，对于应急警力进行调度配置，并优化验证能够保证配置、资金耗费以及社会效益的最优，对于构建高效社会治理，助力社会安全稳定有着积极的作用。The police force consists of police officers, police equipment, police cars, etc. It is an important force in maintaining social stability and sustainable development, and is related to the country's long-term peace and security and the people's livelihood and contentment. However, with the continuous rapid development of the economy and society, it is difficult for the police deployment of public security organs to cover every corner of society in a saturated manner. Especially when emergencies occur, it is often difficult to ensure the normal and efficient deployment of police forces. Therefore, using intelligent digital means to dispatch and configure emergency police forces, and optimizing and verifying them can ensure optimal allocation, capital consumption, and social benefits, and play a positive role in building efficient social governance and promoting social security and stability.
现有的警力配置方法，大多是针对现有的警力配置，考虑不同的影响因素进行多权重的模糊评价。即使是考虑了多元数据，也仅仅是一个优化求解方案，在下达之前缺少预验证环节，缺少对调度方案的可靠性判断。Most of the existing police allocation methods are based on the existing police allocation and carry out multi-weighted fuzzy evaluation considering different influencing factors. Even if multivariate data is taken into account, it is only an optimization solution, lacking a pre-verification link before it is issued, and a lack of reliability judgment on the scheduling plan.
对于警力的配置，要以事故或事件本身的特点为出发点，以现场处警的警力高效紧饱和为核心，囊括影响警力配置的身体特征、物理定位、警械配置、通信条件、警车状态、组队情况、警情变化以及交通天气等关键信息。因此，在这种多元约束下的优化策略问题中，需要实现平衡求解问题的最优化结果。此外，对于警力配置一个重要要求就是可靠性，一旦指令下发，警力就处于执行状态，调度指令对于事件的处理、警员安全以及人民生命财产安全都具有决定性的影响。因此，在下达前，利用数字孪生构建的数字空间进行模拟验证，同时结合实时信息迭代调度方案，保障处警的可靠性是非常必要的。 For the deployment of police force, the starting point should be the characteristics of the accident or event itself, with the efficiency and saturation of the police force at the scene as the core, including physical characteristics, physical positioning, police equipment configuration, communication conditions, police car status, and team formation that affect the deployment of police force. situation, changes in police situation, traffic weather and other key information. Therefore, in this optimization strategy problem under multiple constraints, it is necessary to achieve the optimal result of the balanced solution problem. In addition, an important requirement for police force deployment is reliability. Once an order is issued, the police force is in execution state. Scheduling instructions have a decisive impact on incident handling, police safety, and the safety of people's lives and property. Therefore, before dispatching, it is very necessary to use the digital space constructed by digital twins to conduct simulation verification, and at the same time combine iterative dispatching plans with real-time information to ensure the reliability of police dispatch.
