Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
The embodiment of the invention provides a network car booking method based on a data link, and as shown in fig. 1, a system architecture based on the method comprises a network car booking platform, a plurality of data link nodes, a network car booking and a client, wherein the network car booking platform is communicated through the internet. The plurality of data link nodes form a consensus network, each data link node has a jurisdiction area, and the jurisdiction areas are divided according to urban areas. And the data link node is responsible for the network car booking service in the corresponding jurisdiction area. One jurisdiction may correspond to only one data link node or to a plurality of data link nodes.
After a driver registers own vehicle as a network appointment vehicle on a network appointment platform through a user terminal such as a mobile phone or a PAD (Portable Android Device), the network appointment platform sends access addresses of all data link nodes in a current consensus network and area information of corresponding jurisdiction areas to the network appointment vehicle. In the network car booking travel process, the network car booking can obtain the positioning information of the network car booking travel process, the current jurisdiction area of the network car booking travel process can be determined according to the positioning information of the network car booking travel process, and then the data link node for processing the network car booking service corresponding to the network car booking travel process is determined.
The client of the network appointment is installed on a passenger terminal such as a mobile phone or a PAD of a passenger, and when the passenger logs in the network appointment platform through the client for the first time, the network appointment platform sends the access address of each data link node and the corresponding regional information of the jurisdiction area to the client. The client stores the corresponding relation between the access address of each data link node and the area information. And then, after the data link nodes in the consensus network change, when the client logs in the network appointment platform, the network appointment platform sends the changed access addresses of the data link nodes and the corresponding area information to the client, and the client updates the locally stored access addresses of the data link nodes and the corresponding area information.
When a passenger contracts on the internet, the passenger inputs origin information and destination information in an interface of a client, the client acquires the origin information, the destination information and a contact mode of the passenger, determines a jurisdiction area to which the origin information belongs according to the origin information and locally stored area information, acquires an access address of a data link node corresponding to the jurisdiction area, and sends a contract request to the data link node corresponding to the jurisdiction area according to the access address, wherein the contract request carries the origin information, the destination information and the contact mode of the passenger. Then, as shown in fig. 2, the data link node implements the network car-booking service of the passenger according to the following operations of step 101 and step 103, which specifically includes:
step 101: and the data link node receives a car booking request sent by the client, wherein the car booking request carries origin information and destination information, and the origin information is positioned in a jurisdiction area corresponding to the data link node.
Step 102: and the data link node selects one network appointment vehicle from the network appointment vehicles currently in the own jurisdiction area according to the appointment request.
When the data link node receives a car appointment request sent by a passenger, the data link node firstly locates all network appointment cars currently in the jurisdiction area of the data link node. Specifically, the data link node broadcasts a positioning query instruction, the positioning query instruction is used for indicating the network appointment car receiving the instruction to return the relevant information of the vehicle, and the radiation range of the positioning query instruction is the jurisdiction area of the data link node. The vehicle related information comprises driver identity information, driver contact information, vehicle identification, vehicle model, vehicle color, vehicle positioning information, vehicle state information and the like, and the vehicle identification can be a license plate number, and the vehicle state information can be in a busy state or an idle state. And after receiving the positioning query instruction, the network appointment vehicle currently located in the jurisdiction area of the data link point sends the vehicle related information of the network appointment vehicle to the data link node.
And the data link points analyze the vehicle related information of each network appointment vehicle and identify the vehicle state information of each network appointment vehicle, so that the network appointment vehicle in an idle state in all the network appointment vehicles is determined. And the data link point selects one network appointment vehicle from the network appointment vehicles in the idle state according to the appointment request.
In the embodiment of the invention, the data link point can randomly select one network appointment vehicle from the network appointment vehicles in the idle state, and can also select one network appointment vehicle with the optimal route from the network appointment vehicles in the idle state.
Specifically, when a network appointment is selected, the data link nodes respectively determine the nearest route between each network appointment vehicle in the idle state and the origin information. Specifically, for each network appointment vehicle in the idle state, the data link nodes acquire vehicle positioning information from vehicle related information of the network appointment vehicle, and determine a nearest route from the current position of the network appointment vehicle to a passenger-specified origin according to the vehicle positioning information, origin information included in the appointment request and a road map of a jurisdiction corresponding to the data link nodes. In the embodiment of the present invention, the closest route may be a route with the shortest travel among all routes from the network appointment to the starting place, or may be a route with the least time consumption among all routes.
And after the data link points determine the corresponding nearest route of each network appointment vehicle in the idle state, selecting the network appointment vehicle with the shortest time consumption in the nearest route from the network appointment vehicles in the idle state. When the nearest route is the route with the shortest travel, the data link nodes firstly estimate the time consumption duration of the nearest route corresponding to each network car appointment, and then select the network car appointment with the shortest time consumption duration from each network car appointment. And when the nearest route is the route which consumes the least time, directly selecting the network appointment vehicle which consumes the shortest time from the network appointment vehicles.
Step 103: and the data link node sends a task assignment message to the selected network appointment vehicle, wherein the task assignment message comprises the origin information and the destination information.
And after selecting one network appointment vehicle, the data link node sends a task assignment message to the selected network appointment vehicle, wherein the task assignment message comprises the origin information and the destination information. And after receiving the task assignment message, the network appointment vehicle plans an optimal route from the current position of the network appointment vehicle to the position indicated by the origin information, wherein the optimal route is the route which consumes the least time in all routes from the current position of the network appointment vehicle to the origin. And after the optimal route of the network appointment planning place is planned, the network appointment planning place goes to the origin appointed by the passenger according to the optimal route. The task assignment message also comprises a contact way of the passenger, and when the net appointment vehicle arrives near the starting place, the driver can contact the passenger according to the contact way of the passenger so that the passenger can find the net appointment vehicle and get on the vehicle as soon as possible. The passengers get on the back network and plan an optimal route from the starting place to the destination, and depart to the destination according to the optimal route.
And after the network appointment vehicle reaches the position indicated by the destination information, the network appointment vehicle generates a bill according to the mileage of the current journey and the driving time, and sends the bill to the client corresponding to the passenger. The passenger checks the account and submits a payment request after confirmation. After receiving a payment request submitted by a user, a client sends fare transaction information to a data link node, wherein the fare transaction information comprises mileage of a current trip, running time, fare number, passenger account information, driver account information and the like.
And the data link point receives the fare transaction information uploaded by the client, verifies the fare transaction information through an intelligent contract and completes fare transaction operation when the fare transaction information passes the verification. When the intelligent contract verifies the fare transaction information, the data link node deducts the fare amount from the passenger account and adds the fare amount to the driver account.
And after the fare transaction operation is finished, the data link points generate data blocks according to the vehicle related information, the car booking request and the fare transaction information of the network car booking. The data link node adds the data block to the data chain stored in the data link node. The data link nodes store the vehicle related information, the fare transaction information, the origin information, the destination information, the passenger contact information and the like carried in the car booking request in the data link, the data in the data link cannot be falsified, the authenticity is strong, the data are accumulated for subsequent data analysis of the network car booking service, and the data can also be used as evidence when disputes occur between a driver and passengers.
And the data link node broadcasts the data block to other data link nodes in the consensus network for storage. After other data link nodes receive the data block, the data block is added to the respective stored data chain. Therefore, each data link node in the consensus network is ensured to store the data block, and even if a single data link node fails or data is lost, the data block can be acquired from other data link nodes in the consensus network, so that the data security is high.
Alternatively, the data link node may not send the data block to each other data link node in the consensus network, but only send the data block to other data link nodes corresponding to the jurisdiction region of the data link node for storage. In the embodiment of the present invention, one jurisdiction may correspond to a plurality of data link nodes, that is, a network car booking service in one jurisdiction may be jointly responsible for by a plurality of data link nodes. And when each other data link point corresponding to the jurisdiction region receives the data block, adding the data block into the respective stored data chain. Therefore, each data link node corresponding to the jurisdiction region stores the data block, so that even if a certain data link point corresponding to the jurisdiction region fails or data is lost, the data block can be acquired from other data link nodes, and the data security is high.
In the embodiment of the present invention, when a network car booking service in one jurisdiction is set to be in charge of a plurality of data link nodes, after the data link nodes receive a car booking request in step 101, the data link nodes first determine whether the current load of the data link nodes reaches a preset threshold, and if not, step 102 is executed to select a network car booking from the network car booking currently in the jurisdiction. In the embodiment of the present invention, the current load of the data link node is the number of car booking requests currently processed by the data link node, and the preset threshold may be 10 or 15, etc.
And when the data link node judges that the current load of the data link node reaches a preset threshold value, the taxi appointment request is broadcasted to other data link nodes corresponding to the jurisdiction area of the data link node, so that the data link node with the current load smaller than the preset threshold value in the other data link nodes processes the taxi appointment request.
When other data link points receive the car booking request, the current load of the other data link points is judged whether to reach the preset threshold value or not, and if so, the car booking request is discarded. If not, the process is executed from step 102 to process the car-appointment request.
In order to avoid that no data link node processes the car booking request or multiple data link nodes simultaneously exist to process the car booking request, in the embodiment of the invention, other data link nodes also return the judgment result to the data link node after judging whether the current load of the other data link nodes reaches the preset threshold value, and if the judgment result received by the data link node shows that the current loads of the other data link nodes all reach the preset threshold value, the data link node is responsible for processing the car booking request. And if the judgment result received by the data link node shows that the current load of one data link node is smaller than the preset threshold value in other data link nodes, the data link node with the current load smaller than the preset threshold value is responsible for processing the taxi appointment request. And if the judgment result received by the data link node shows that the current loads of a plurality of data link nodes in other data link nodes are smaller than the preset threshold value, the data link node randomly indicates one of the plurality of data link nodes with the current loads smaller than the preset threshold value to process the taxi appointment request.
