[0019] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments and the accompanying drawings, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.
[0020] Example 1: See Figure 1 The purpose of this embodiment is to provide a command and dispatch method for sudden urban management events.
[0021] S1. Determine whether the received urban management event is a risk event.
[0022] The urban management incidents currently handled by the applicant mainly come from the collection and reporting of collectors, WeChat applet reports, collection vehicles, video surveillance systems, etc. After the applicant receives the reported case information through the smart urban management platform, if it is an ordinary incident, the case will be sent to the corresponding department for disposal. If the reported case is a sudden risk event, emergency handling is required.
[0023] When receiving a city management event, the present invention first determines whether the event is a risk event.
[0024] Specifically, it is determined whether the event type exists in the risk event database. The risk event database stores information such as the event type of risk events, all risk levels included in each event, and the materials and quantities required for emergency response for each risk level of each event.
[0025] S2. If yes, conduct a risk assessment on the event and obtain the corresponding risk level.
[0026] When an event is a risk event, a risk assessment is conducted on the event to obtain the corresponding risk level of the event. The greater the risk of the event and the more likely it is to cause a huge impact, the higher the risk level.
[0027] The risk level of the present invention is divided into four levels, namely general risk, greater risk, major risk and extremely large risk. For different risk events, different risk levels also correspond to different emergency material needs. Therefore, by determining the risk level of the event, targeted material dispatch measures can be taken.
[0028] The risk level can be manually determined based on information such as the incident situation, the location of the incident, and the environment surrounding the incident.
[0029] It can also be determined automatically. First, Get the risk value P of the event; S is the intensity value of the event. Different event types use different intensity value representation methods. For example, for a water pipe rupture event, the size of the leak is used as the event intensity; R represents the impact value of the event, where - Respectively represent the impact of the event on human life, economy, infrastructure, ecological environment and social environment, - The values are all between 0 and 5. After the risk value is obtained, the risk level of the event is determined according to the risk values corresponding to the different risk levels of the corresponding event type.
[0030] S3. Obtain the materials needed for emergency response based on the type of incident and the corresponding risk level.
[0031] According to the event type and the corresponding risk level, the types and quantities of materials required for emergency response are obtained from the risk event database. For example, in the case of ground collapse, emergency response requires materials such as cordons, warning fences, and reflective cones. Different risk levels require different types and quantities of materials.
[0032] S4. Obtain the vehicle dispatch strategy based on the current location of the dispatchable vehicle and the storage location of the materials required for emergency handling.
[0033] This step obtains material-related information from the material database and vehicle-related information from the vehicle database. The material database stores information such as the name of the emergency material, the storage point of the material, the storage quantity of each storage point, and the volume weight of a single material; the vehicle database stores information such as the vehicle type, the rated cargo volume weight of the vehicle, the idle state of the vehicle, and the current location of the vehicle.
[0034] First, the inventory quantity, storage location, weight, volume and other information of the materials needed for emergency response are obtained from the materials database. The required materials are expressed as , Indicates information related to the sth material. The storage points involved in these s types of materials are represented as , represents the wth storage point, Then, the rated cargo weight, rated cargo volume, and current location of idle vehicles that can carry and transport the required emergency supplies are obtained from the vehicle database; the obtained vehicles are represented as , represents the vth vehicle, .
[0035] The scheduling model is then used to schedule vehicles. The scheduling model takes the shortest vehicle distance as the objective function, and the objective function is expressed as , where L is the total distance traveled by all vehicles, i is the depot number, j is the vehicle number, Indicates vehicle Is it in the warehouse? Loading materials, the corresponding values are 1 and 0 respectively; Indicates vehicle Go to the warehouse The distance to load supplies and transport them to the location of the incident. , where function d is used to obtain the distance between two locations, dest represents the location where the event occurred, that is, Indicates vehicle Current location and storage point The length of the distance between Indicates the warehouse point The method of obtaining the distance between two locations is a conventional technique and will not be described in detail.
[0036] The scheduling model has the following constraints: , , Indicates vehicle From the library The materials loaded The number of Indicates materials The required quantity, Indicates vehicle Is it in the warehouse? Loading materials, the corresponding values are 1 and 0 respectively, Indicates vehicle Is the cargo loaded? , the corresponding values are 1 and 0. This constraint means that the quantity of a certain material transported by all vehicles should be consistent with the required quantity.
[0037] , , , Indicates vehicle From the library The materials loaded The number of Indicates the warehouse point China Materials This constraint means that the quantity of a certain material loaded by all vehicles from a certain storage point cannot exceed the inventory quantity of the corresponding material in the storage point.
[0038] , This constraint means that each vehicle only goes to one warehouse to transport materials (the cumulative result is 1), or the vehicle is not called, that is, the vehicle does not go to any warehouse (the cumulative result is 0).
[0039] , ,in Indicates vehicle Rated cargo weight, Indicates vehicle Rated cargo volume, Indicates materials The unit weight, Indicates materials The unit volume, Indicates materials This constraint means that the dispatched vehicles should be able to carry the materials to be transported.
[0040] Finally, according to the required materials S, the storage points W involved and the dispatchable vehicles V, the dispatch model is solved to obtain the vehicle dispatch strategy.
[0041] The vehicle dispatch strategy includes the dispatched vehicles, the depots to which each vehicle goes, the materials loaded by each vehicle at the depot, and the quantity loaded.
[0042] S5. Dispatch vehicles to transport materials according to the vehicle dispatch strategy.

[0044] The risk assessment module is used to determine whether the received city management event is a risk event, and to obtain the risk level of the risk event. In combination with embodiment 1, the obtaining module is used to execute steps S1-S2.
[0045] The material acquisition module is used to acquire materials required for emergency treatment according to the event type and the corresponding risk level. In combination with Example 1, the correction module is used to execute step S3.
[0046] The dispatch module is used to obtain the vehicle dispatch strategy according to the current location of the dispatchable vehicle and the storage location of the materials required for emergency treatment, and to dispatch the vehicle to transport the materials according to the vehicle dispatch strategy. In combination with Example 1, the pre-processing module is used to execute steps S4-S5.
