Detailed Description
In order to more clearly explain the overall concept of the present application, the following detailed description is given by way of example in conjunction with the accompanying drawings.
The embodiment of the application discloses a real-time maintenance method of a shared automobile, which comprises the following steps as shown in fig. 1:
step 101, a server receives a fault maintenance request message from a terminal.
In the embodiment of the application, the fault maintenance request message comprises geographic position information of a target shared automobile corresponding to the terminal user, a vehicle model of the target shared automobile and first fault data of the target shared automobile; wherein the first failure data is failure data determined by an end user. For example, the user sends characters such as "vehicle damaged", "vehicle not flameout", "tire abnormal", "unable to start" to the server through the mobile phone, and sends corresponding photos to the server as the first fault data. In addition, the user may send the license plate number of the target shared automobile to the server, so that the server determines the geographic location information of the target shared automobile and the vehicle model of the target shared automobile.
And step 102, the server acquires second fault data of the target shared automobile through the vehicle-mounted diagnosis equipment of the target shared automobile.
In the embodiment of the application, the vehicle-mounted diagnostic equipment can enter an electronic control unit of an engine, a gearbox, an anti-lock System and the like to read fault codes and other related data, and automatically sends information such as identity codes, fault codes and positions of vehicles to a server by using a vehicle-mounted communication System, for example, a Global Positioning System (GPS) navigation System or a wireless communication mode.
The second fault data includes, but is not limited to: the vibration signal of each bearing in the vehicle power assembly, oil consumption parameters, throttle temperature parameters, air inlet pipe pressure parameters, air inlet temperature parameters, air inlet flow and one or more of coolant temperature. The vibration signal of each bearing is used for representing the wear degree of the bearing, because the bearing surface can be damaged to different degrees due to fatigue after long-time running, such as cracks and surface falling, and the damage of the bearing surface can cause the bearing vibration.
And 103, the server determines the fault type of the target shared automobile according to the first fault data and/or the second fault data in the fault maintenance request message.
Usually, the master control device on the shared automobile can prompt a certain part of the automobile to have a fault, but cannot indicate the fault reason, and needs to be comprehensively checked by a maintenance worker, so that the real-time maintenance efficiency of the shared automobile is reduced. In order to solve the above problem, in the embodiment of the present application, the server determines the fault type of the target shared automobile according to the first fault data and/or the second fault data, so that a serviceman can determine the fault cause according to the fault type.
As shown in step 102, the data type of the first failure data may be characters or pictures, and the data type of the second failure data may be vibration signals, failure codes, signals corresponding to other sensors, and the like. Therefore, the server cannot directly perform data processing using the first failure data and/or the second failure data, and a plurality of pieces of failure feature data need to be extracted from the first failure data and/or the second failure data.
In order to determine the fault type more accurately, fault feature data of multiple dimensions needs to be acquired. However, the difficulty of data processing is greatly increased by multiple dimensions, and therefore, in the embodiment of the present application, the dimensions need to be reduced by merging fault data sets to reduce the difficulty of data processing, and the specific steps are as follows:
firstly, each fault feature data is regarded as a fault data set, and the servers determine the Euclidean distance between a plurality of fault data sets pairwise, for example, if the fault data set A, B, C exists, the servers respectively determine the Euclidean distance between A and B, the Euclidean distance between B and C and the Euclidean distance between A and C. And merging the two fault data sets with the minimum Euclidean distance.
And the server repeatedly executes the step of determining the Euclidean distance and the step of combining the sets until the Euclidean distance between any two fault data sets reaches a preset threshold value. In the above loop process, only two fault data sets are merged in each loop process, and the euclidean distance between the two merged fault data sets is the minimum, so as to ensure the uniqueness of elements in the fault data sets. For example, there are four fault feature data sets, 1, 2, 3, 4, corresponding to four fault data sets a, b, c, d, respectively, and if the euclidean distance between the set a and the set b is the minimum and does not reach a preset threshold, three sets, e, c, d, are obtained after merging, where the elements in the set e are 1, 2. At this time, if the euclidean distance between the set c and the set e is the minimum and does not reach the preset threshold, two sets f and d are obtained after combination, wherein elements in the set f are 1, 2 and 3.
By the method, the corresponding relation between each fault characteristic data and the fault type is converted into the corresponding relation between the fault data set and the fault type, so that the data processing dimensionality is reduced. And finally, the server determines the fault type corresponding to each fault data set by using the fault characteristic data in each combined fault data set. For example, a training vector of the artificial neural network is constructed using the set of fault data such that the artificial neural network determines the type of fault from the set of fault data. After training is completed, when the artificial neural network inputs vectors corresponding to the received first fault data and/or second fault data, the artificial neural network automatically determines the fault type corresponding to the target shared automobile.
And step 104, the server determines a maintenance node corresponding to the target shared automobile according to one or more of the fault type of the target shared automobile, the geographical position information of the target shared automobile in the fault maintenance request message and the vehicle model of the target shared automobile in the fault maintenance request message.
In the embodiment of the present application, if only the geographical location information of the target sharing automobile is considered, the server may select a maintenance node closest to the target sharing automobile, where the maintenance node includes, but is not limited to: individuals, businesses, and 4S stores that specialize in providing vehicle repair services. In addition, the embodiment of the application also provides two other methods for determining the maintenance node:
in the first method, the server determines a preset area identifier corresponding to the target shared automobile according to the geographical location information of the target shared automobile, where the area identifier may be set by itself, for example, A, B, C district, or an identifier corresponding to an administrative area, for example, an identifier corresponding to each province, each city, each district and county.
And the server determines a maintenance node set consisting of a plurality of maintenance nodes in the area corresponding to the preset area identification according to the fault type of the target shared automobile and/or the vehicle model of the target shared automobile. The server determines a selection range of a service node in a specific area to reduce data processing amount, thereby improving vehicle maintenance efficiency. For example, the target shared automobile model is Beijing modern, if the search area is not limited, the server can search modern 4S stores nationwide, and if the search area is limited to Beijing, the server can only search the modern 4S stores nationwide, so that the workload of the server is greatly reduced.
The server respectively determines the geographical position information of each maintenance node in the maintenance node set, and then determines the maintenance node closest to the target shared automobile according to the geographical position information of the target shared automobile and the geographical position information of each maintenance node in the maintenance node set.
In contrast to the first method, the second method requires that the server also defines the region and determines the set of repair nodes according to the type of failure of the target shared automobile and/or the vehicle model of the target shared automobile. And then the server does not appoint the maintenance node according to the distance, but selects the maintenance node in a form of order grabbing. For example, there are A, B, C three repair nodes in the set of repair nodes, the server broadcasts repair orders to A, B, C three repair nodes, and if the A repair node receives the repair order and sends the order pickup data to the server first, the server selects the A repair node.
It can be understood that the first method focuses on saving the time for sending the target shared automobile to the maintenance node, and the second method focuses on letting the maintenance node select whether to take an order or not according to the busy situation of the own service, so as to reduce the waiting time of the shared automobile in the maintenance process. In practical application, the server can select the maintenance node by using the first method or the second method according to an actual scene, so that the maintenance efficiency is improved.
And 105, the server sends one or more of the fault type of the target shared automobile, the geographical position information of the target shared automobile and the vehicle model of the target shared automobile to a maintenance node.
In summary, the technical scheme provided by the embodiment of the application improves the maintenance efficiency from the aspects of fault diagnosis, maintenance node selection and the like.
In order to facilitate the maintenance node to quickly receive the target shared automobile, in the embodiment of the application, the server navigates the automobile taking route of the maintenance node. For example, after the server determines that the garage A is a maintenance node, the server determines the geographical position information of the garage A; determining route data from the garage A to the target shared automobile according to the geographical position information of the garage A and the geographical position information of the target shared automobile; and finally, the server sends the route data to the garage A.
Sometimes, the fault of the shared automobile is caused by a user, and in order to determine a responsible party, in the embodiment of the application, the server acquires a plurality of pieces of driving route data and driving time corresponding to each piece of driving route data from driving recording equipment on the target shared automobile, that is, acquires the driving track of the target shared automobile in each time period, and each time period can be divided by a parking time node; the server correspondingly stores the first fault data and/or the second fault data, the driving route data, the driving time and the driver identity information, namely the first fault data and/or the second fault data, the driving route data, the driving time and the driver identity information are bound to make a responsibility party clear; and the server sends the corresponding stored data to the corresponding terminal according to the driver information, receives the user signature data from the corresponding terminal, and enables the user to confirm the stored data so as to further clarify the responsible party.
In order to solve the above problem, in the embodiment of the present application, after the server receives vehicle maintenance completion information from the maintenance node, the server acquires state data of the target shared vehicle through a vehicle-mounted diagnostic device on the target shared vehicle; and the server determines a maintenance result of the target shared automobile according to the state data and the first fault data and/or the second fault data, and sends the maintenance result to the maintenance node. Therefore, the technical scheme provided by the embodiment of the application can realize the remote online detection of the maintenance result of the shared vehicle, so that the working efficiency of maintenance personnel is improved.
In the embodiment of the application, before the user uses the shared automobile, the server recommends the vehicle insurance and additional insurance, such as vehicle damage insurance and non-indemnity insurance, to the user. After the shared vehicle completes the repair, the server receives repair billing data from the repair node. At this time, the server determines whether the terminal user purchases the corresponding insurance; after determining that the user purchases the insurance transaction, the server calculates a repair fee for the target shared automobile based on the type of failure, the repair billing data, and the type of insurance.
