In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The fault analysis data processing method of the vehicle-mounted terminal can be applied to the application environment shown in fig. 1. The vehicle-mounted terminal is provided with a port, the port is used for realizing interaction between the vehicle-mounted terminal and the data transmission equipment, and the data transmission equipment can be connected to a data transmission network and is in a networking state. If the vehicle-mounted terminal has a fault, the fault analysis platform can be used for carrying out fault analysis. In the case that the vehicle-mounted terminal can be connected to the data transmission network and is in a networking state, the vehicle-mounted terminal can transmit the fault analysis data to the fault analysis platform via the data transmission network. When the vehicle-mounted terminal cannot be connected to the data transmission network and is in the non-networking state, the vehicle-mounted terminal can send the fault analysis data to the data transmission equipment through a preset port; the data transmission equipment is connected to a data transmission network, enters a networking state, and transmits fault analysis data to the fault analysis platform through the data transmission network; and after receiving the fault analysis data, the fault analysis platform analyzes the fault of the vehicle-mounted terminal to determine a fault point of the vehicle-mounted terminal.
In one embodiment, as shown in fig. 2, a method for processing fault analysis data of a vehicle-mounted terminal is provided, which is described by taking the method applied to the vehicle-mounted terminal in fig. 1 as an example, and includes the following steps:
step S201, if the vehicle-mounted terminal to be subjected to fault analysis is in a non-networking state, determining a port which is reserved in the vehicle-mounted terminal and aims at data transmission equipment;
step S202, sending fault analysis data to the data transmission equipment in the networking state through the port, so that the data transmission equipment sends the fault analysis data to the fault analysis platform in the networking state to perform fault analysis on the vehicle-mounted terminal.
Wherein the networking is to connect to a data transmission network for the fault analysis platform; the networking state is that the device is connected to the data transmission network; the networking state refers to the capacity of equipment (such as a vehicle-mounted terminal, data transmission equipment, a fault analysis platform and the like) to be connected to the data transmission network; the non-networkable state refers to a device not having the capability to connect to the data transmission network described above. The fault analysis data may include real-time operating voltage data of the in-vehicle terminal, communication data between the in-vehicle terminal and the vehicle, and the like.
If the traffic owned by the in-vehicle terminal for using the data transmission network is insufficient or the networking unit of the in-vehicle terminal has a circuit failure, the in-vehicle terminal does not have the capability of connecting to the data transmission network and is in a non-networking state. Under the condition that the vehicle-mounted terminal is in a non-networking state, if the vehicle-mounted terminal breaks down, the fault analysis data cannot be sent to the fault analysis platform through the data transmission network to carry out fault point analysis on the vehicle-mounted terminal. At this time, since the data transmission device has the capability of being connected to the data transmission network and is in a network-connectable state, after the wired connection between the vehicle-mounted terminal and the data transmission device can be realized in a port plugging mode, the vehicle-mounted terminal sends the fault analysis data to the data transmission device through the reserved port; after receiving the fault analysis data, the data transmission equipment sends the fault analysis data to a fault analysis platform through a data transmission network; and the fault analysis platform analyzes fault points of the vehicle-mounted terminal based on the fault analysis data.
In the fault analysis data processing method of the vehicle-mounted terminal, if the vehicle-mounted terminal cannot be connected to a data transmission network and is in a non-networking state, fault analysis data can be sent to the fault analysis platform through a port reserved in the vehicle-mounted terminal and data transmission equipment in the networking state, so that the fault analysis platform can analyze faults of the vehicle-mounted terminal, an owner does not need to send the vehicle-mounted terminal back, remote fault analysis aiming at the non-networking vehicle-mounted terminal is realized, and the fault analysis efficiency of the vehicle-mounted terminal is improved; in addition, according to the method, the ports are reserved in the vehicle-mounted terminals and the data transmission equipment is used for carrying out networking transmission, so that remote fault analysis on the vehicle-mounted terminals which cannot be networked is realized, meanwhile, other vehicle-mounted terminals with the reserved ports can also carry out networking transmission on fault analysis data through the data transmission equipment, one data transmission equipment is used for a plurality of vehicle-mounted terminals, and the production cost is reduced.
In some embodiments, the port reserved in the vehicle-mounted terminal may include a plurality of pins, and each pin may be used to implement different functions, such as supplying power to the data transmission device, performing working voltage acquisition on the data transmission device, performing serial communication (transmitting data and receiving data) with the data transmission device, and the like, so that the pin may be regarded as a sub-port having different functions; the sub-port for sending data to the data transmission device and the sub-port for receiving data from the data transmission device may be referred to as a serial port, the sub-port for supplying power to the data transmission device may be referred to as a voltage supply sub-port, and the sub-port for collecting operating voltage for the data transmission device may be referred to as a voltage collection sub-port.
In an embodiment, when the vehicle-mounted terminal executes the step S202, the following steps may be specifically executed: and sending communication data to the data transmission equipment in the networking state through the data sending sub-port of the port. The communication data is communication data between the vehicle-mounted terminal and a vehicle where the vehicle-mounted terminal is located; and the communication data is used for the fault analysis platform to determine whether the communication firmware of the vehicle-mounted terminal is matched with the communication firmware of the vehicle.
That is to say, if the vehicle-mounted terminal to be subjected to fault analysis is in a non-networking state, the vehicle-mounted terminal can send communication data to the data transmission equipment through the data sending sub-port, wherein the communication data is communication data between the vehicle-mounted terminal and a vehicle where the vehicle-mounted terminal is located; the data transmission equipment sends the communication data to a fault analysis platform through a data transmission network; the fault analysis platform analyzes whether the communication firmware of the vehicle-mounted terminal is matched with the communication firmware of the vehicle or not based on the communication data; if the communication protocols are not matched, the communication protocols between the vehicle-mounted terminal and the vehicle are not matched, the communication between the vehicle-mounted terminal and the vehicle is problematic, and the communication between the vehicle-mounted terminal and the vehicle belongs to a fault point of the vehicle-mounted terminal.
Further, in the case that the communication firmware characterizing the vehicle-mounted terminal based on the fault analysis result of the communication data does not match the communication firmware of the vehicle in which the vehicle-mounted terminal is located, the vehicle-mounted terminal may further perform the following steps: acquiring communication firmware provided by the fault analysis platform through a data receiving sub-port of the port and the data transmission equipment; the communication firmware provided by the fault analysis platform is matched with the communication firmware of the vehicle where the vehicle-mounted terminal is located; therefore, the vehicle-mounted terminal can communicate with the vehicle where the vehicle-mounted terminal is located by using the communication firmware provided by the fault analysis platform.
In the above embodiment, after the fault analysis platform acquires the communication data of the vehicle-mounted terminal through the data transmission device, it may analyze whether the communication between the vehicle-mounted terminal and the vehicle has a problem that the communication protocol is not matched; if the communication firmware is matched with the communication firmware of the vehicle, the fault analysis platform can send the communication firmware matched with the communication firmware of the vehicle to the vehicle-mounted terminal through the data transmission equipment and the corresponding serial port, so that the vehicle-mounted terminal and the vehicle can normally communicate based on the matched communication protocol.
In an embodiment, when the vehicle-mounted terminal executes the step S202, the following steps may be further specifically executed: and sending the available traffic data to the data transmission equipment in the networking state through the data sending sub-port of the port. The available flow data is used for the fault analysis platform to determine whether the non-networking state of the vehicle-mounted terminal is caused by insufficient available flow.
That is, the vehicle-mounted terminal can also send available flow data to the data transmission device via the serial port; after the fault analysis platform acquires the available flow data through the data transmission equipment, the fault analysis platform can analyze the available flow of the vehicle-mounted terminal to determine whether the non-networking state of the vehicle-mounted terminal is caused by insufficient available flow.
If the fault analysis platform determines that the non-networking state of the vehicle-mounted terminal is caused by insufficient available flow, the fault analysis platform can supplement the available flow of the vehicle-mounted terminal through a network operator so as to enable the vehicle-mounted terminal to be in the networking state, and other fault points can be analyzed conveniently.
In addition, if the fault analysis platform determines that the networking function of the vehicle-mounted terminal is stopped by the network operator based on the available flow data, the fault analysis platform can also activate the vehicle-mounted terminal through the network operator so that the vehicle-mounted terminal is in a networking state, and other fault points can be analyzed conveniently.
In one embodiment, when executing step S202, the vehicle-mounted terminal may further execute the following steps: transmitting real-time working voltage data to the data transmission equipment in a networking state through a voltage acquisition sub-port of the port; and the real-time working voltage data is used for the fault analysis platform to determine whether a circuit of the vehicle-mounted terminal has a fault.
That is, when the vehicle-mounted terminal cannot be networked normally and the fault analysis platform cannot read the real-time working voltage of the vehicle-mounted terminal normally, the fault analysis platform can acquire the real-time working voltage data of the vehicle-mounted terminal through the data transmission device and the voltage acquisition sub-port; after the fault analysis platform determines that the real-time working voltage data are abnormal working voltage data, the circuit of the vehicle-mounted terminal can be judged to be abnormal. Further, the fault analysis platform can also remind the vehicle owner to send the vehicle-mounted terminal to a worker for circuit maintenance of the vehicle-mounted terminal.
In one embodiment, the vehicle-mounted terminal may further perform the following steps: providing a vehicle voltage to the data transfer device via a voltage providing sub-port of the port to cause the data transfer device to enter the networking state from an unconnected state based on the vehicle voltage; wherein the vehicle voltage is a voltage of a vehicle in which the in-vehicle terminal is located.
In the above embodiment, the sub-port is provided by the reserved voltage, so that the data transmission device can normally enter a networking state to transmit the fault analysis data.
In one embodiment, the installation position and the working state indicator lamp of the vehicle-mounted terminal on the vehicle are placed within the shooting range of the camera of the data transmission device; and the image shot by the shooting device in the shooting range is used for the fault analysis platform to determine whether the installation position of the vehicle-mounted terminal meets the standard installation position or not, or the fault analysis platform carries out fault analysis on the vehicle-mounted terminal according to the lighting mode of the working state indicator lamp.
Exemplarily, a camera of the data transmission device can perform video monitoring on the installation position of the vehicle-mounted terminal and the lighting mode of the working state indicator lamp; the fault analysis platform determines that the vehicle-mounted terminal is not installed properly through the video collected by the camera, and then the vehicle owner can be reminded to install the vehicle-mounted terminal according to the standard installation position; in addition, the fault analysis platform analyzes a lighting mode of the working state indicator lamp through a video acquired by the camera, and if the brightness mode is inconsistent with a preset lighting mode, the fault corresponding to the preset lighting mode is determined to exist in the vehicle-mounted terminal; for example, if the preset lighting pattern is a lighting pattern for GPS positioning, if the lighting pattern for the operation status indicator lamp does not coincide with the lighting pattern for GPS positioning, it is determined that the GPS of the in-vehicle terminal has a problem. The preset lighting mode can also be a lighting mode of bus communication, network communication, GPS positioning, a gravity acceleration sensor and the like.
In an embodiment, when the vehicle-mounted terminal executes the step S202, the following steps may be specifically executed: acquiring a first function definition file aiming at the port; the first function definition file corresponds to a function of transmitting fault analysis data through a port; sending failure analysis data to the data transfer device in a network-enabled state via a port that configures the first function definition file.
The vehicle-mounted terminal can interact with the data transmission equipment by using the port to analyze the fault, and at the moment, the port can be considered to have the function of transmitting fault analysis data; the vehicle-mounted terminal can also perform communication interaction with the vehicle by using the port so as to monitor the vehicle, and at the moment, the port can be considered to have the function of transmitting vehicle communication data. The functions provided by the ports can be set by developers through function definition files.
In the implementation, if the vehicle-mounted terminal is in the non-networking state, it indicates that the port should be used for interacting with the data transmission device at this time to implement remote fault analysis; at this time, the vehicle-mounted terminal configures a first function definition file corresponding to the corresponding fault analysis function for the port, so that each pin of the defined port is respectively used for supplying power to the data transmission device, collecting working voltage for the data transmission device, performing serial communication (sending data and receiving data) with the data transmission device, and the like. The vehicle-mounted terminal configures a target function definition file for the port, and interacts with data transmission equipment through the port, such as power supply, working voltage acquisition and serial communication for the data transmission equipment, so as to realize fault analysis.
Further, the vehicle-mounted terminal can also execute the following steps: if the vehicle-mounted terminal enters the networking state from the non-networking state, acquiring a second function definition file aiming at the port; the port corresponding to the second function definition file has the function of transmitting vehicle communication data; and communicating with the vehicle where the vehicle-mounted terminal is located through the port configured with the second function definition file.
That is to say, after the vehicle-mounted terminal recovers from the networking unavailable state to the networking available state, the vehicle-mounted terminal can communicate with the vehicle by using the port, so that vehicle monitoring of the vehicle speed, the vehicle oil consumption and the like is realized. At this time, the in-vehicle terminal may configure a second function definition file of a function of communicating with the vehicle for the port, and communicate with the vehicle via the port to perform vehicle state monitoring.
Therefore, under the condition that the networking unit of the vehicle-mounted terminal is normal (the vehicle-mounted terminal is in a networking state), at the moment, other function definitions can be carried out on the reserved port, the multifunctional multiplexing of the port is realized, and the production cost of the vehicle-mounted terminal is reduced.
In order to better understand the method, an application example of the fault analysis data processing method of the vehicle-mounted terminal is explained in detail below.
When the vehicle-mounted terminal with the fault is in the state of being incapable of being networked, the fault analysis data of the vehicle-mounted terminal cannot be uploaded to the fault analysis platform through the network. Aiming at the situation, the application example can realize remote fault point analysis and online maintenance of the non-network-connected vehicle-mounted terminal so as to meet the requirements of accurate positioning and field maintenance of the fault point of the fault vehicle-mounted terminal and reduce the time for the fault vehicle-mounted terminal to be shipped back and forth.
The application example mainly comprises the following functions:
firstly, a fault detection maintenance board (equivalent to data transmission equipment) is added for secondary networking on the basis of primary networking of the vehicle-mounted terminal, so that the problem judgment when the vehicle-mounted terminal cannot be normally networked is effectively solved;
relevant technicians do not need to judge problems on site, and relevant problem points can be effectively positioned only through background data of the fault detection maintenance board;
when the problem vehicle-mounted terminal can update the firmware in a fault detection and maintenance board serial port debugging mode, the sending time of the problem vehicle-mounted terminal can be effectively saved, and the maintenance efficiency of the vehicle-mounted terminal is improved;
and fourthly, adding a camera to carry out video monitoring on the vehicle-mounted terminal with the problem.
Specifically, as shown in fig. 3, the present application example may include the following:
(1) a debugging port (the port comprises a plurality of pins which respectively correspond to vehicle voltage, a GND (voltage grounding point), a serial port and vehicle terminal main voltage) is reserved in the debugging and developing process of the vehicle terminal, wherein the pin of the vehicle voltage and the pin of the GND are used for supplying power to a fault detection maintenance board, the serial port is used for data communication and firmware upgrade of the maintenance board and the vehicle terminal, and the vehicle terminal main voltage is used for carrying out ADC voltage sampling (namely acquisition of working voltage) on the fault detection maintenance board; as shown in fig. 3, if there are a plurality of main voltages of the vehicle-mounted terminal, voltage collection may be performed through different pins respectively;
(2) the fault detection maintenance board has a networking function, and can send serial port communication data with the vehicle-mounted terminal to the fault analysis platform for fault analysis and judge a fault point of the vehicle-mounted terminal;
(3) when the vehicle-mounted terminal cannot be normally networked and the fault analysis platform cannot read data of the vehicle-mounted terminal through a data transmission network, the vehicle-mounted terminal reserves a debugging port to be accessed to a fault detection maintenance board; the fault analysis platform judges whether the ADC voltage sampling value is normal or not from the data of the fault detection maintenance board, if the voltage is abnormal, the fault analysis platform can judge that a hardware circuit of the vehicle-mounted terminal is in fault, and at the moment, an owner is reminded to send the vehicle-mounted terminal back to a worker for maintenance; if the fault analysis platform finds that the SIM card (Subscriber Identity Module) of the vehicle-mounted terminal is stopped or has no flow through serial port communication, the fault analysis platform can reactivate or supplement the SIM card flow through a network operator, and the vehicle-mounted terminal can be reset for reuse after the operation is finished;
(4) when the vehicle-mounted terminal and the vehicle cannot normally carry out bus communication, related data acquisition can be carried out through a serial port of the fault detection maintenance board, network data are uploaded to a background to carry out data analysis and firmware processing, then the network data are issued to the fault detection maintenance board, and firmware debugging and updating are carried out through the serial port and the vehicle-mounted terminal;
(5) the camera in the fault detection maintenance board can carry out video monitoring on the installation and lighting conditions of the vehicle-mounted terminal, and when the vehicle-mounted terminal is found to be improperly assembled, a vehicle owner can be informed of timely changing at the first time; meanwhile, the corresponding bad points of the vehicle-mounted terminal can be judged according to the lighting condition of the vehicle-mounted terminal, and the lighting modes corresponding to bus disconnection, network disconnection, GPS non-positioning, g-sensor (gravity acceleration sensor) abnormity and the like are inconsistent.
The application example can realize the secondary networking of the vehicle-mounted terminal, and can judge the problem of the vehicle-mounted terminal through background data uploaded by the fault detection maintenance board under the condition that the original vehicle-mounted terminal cannot be normally networked; firmware upgrading can be carried out on the vehicle-mounted terminal through serial port communication between the fault detection maintenance board and the vehicle-mounted terminal; in addition, the camera is added to carry out video monitoring on the fault vehicle-mounted terminal, so that telephone communication between workers and a vehicle owner is avoided, and the problem judgment time of the vehicle-mounted terminal is effectively saved.
