Description
Technical field
The utility model relates to automobile technical field, particularly a kind of OBD (On-BoardDiagnostic, onboard diagnostic system) device.
Background technology
Along with the rise of car networking concepts, orthodox car there is increasing electronic machine, how quick obtaining fault data, diagnosis and prediction fault are the practical problemss that each equipment manufacturer will face, prior art obtains all kinds of diagnostic data from vehicle OBD, by SD (SecureDigitalMemoryCard, safe digital card) card local preserve or depot after sale service technician adopt cable data connection mode to be connected with vehicle-mounted OBD interface by dedicated diagnostic device, thus acquisition diagnostic data.The weak point of this method is, must derive diagnostic data by professional and technical personnel scene, Operation & use is all inconvenient, and data acquisition is delayed, and cannot carry out trouble diagnosing in real time.
Utility model content
The technical problems to be solved in the utility model is that OBD device data acquisition in prior art is inconvenient, the defect of poor real in order to overcome, provide a kind of operation and easy to use, data acquisition timely and can carry out the OBD device of trouble diagnosing in real time.
The utility model solves above-mentioned technical matters by following technical proposals:
A kind of OBD device, be characterized in, comprise central process unit, OBD module, 4G (forth generation vehicular telephone mobile communication standard) communication module, 4G antenna, SIM (user identification module) card, GPS (global positioning system) module and GLONASS (GLONASS satellite navigation system) module; Described OBD module and described 4G communication module are electrically connected with described central process unit respectively; Described 4G antenna, described SIM, described GPS module and described GLONASS module are electrically connected with described 4G communication module respectively.
In this programme, what the diagnostic data that OBD module can obtain by 4G communication module was real-time is transferred to background server, completes fault diagnosis functions in time.
Preferably, described OBD device also comprises the architecture module of the current location information for obtaining described OBD device from nearest base station, and described architecture module is electrically connected with described 4G communication module.
In this programme, described architecture module is used for obtaining the current location information of described OBD device from nearest base station, thus determines the position that is provided with residing for the vehicle of OBD device.
Preferably, described OBD device is connected with described central process unit by OBD interface circuit.
Preferably, described OBD device also comprises Wi-Fi (Wireless-Fidelity, Wireless Fidelity) module and Wi-Fi antenna, and described 4G communication module and described Wi-Fi antenna are electrically connected with described Wi-Fi module respectively.
In this programme, 4G communication module can the Wi-Fi function of enable Wi-Fi module by AT (Hayes Modem commands collection) order, thus realizes passenger on car and connect Wi-Fi Hotspot and surf the Net.
Preferably, described 4G communication module and described Wi-Fi module are connected by SPI (SerialPeripheralInterface, Serial Peripheral Interface (SPI)).
Preferably, described 4G communication module and described central process unit are connected by USB (UniversalSerialBus, USB) interface.
Preferably, described 4G communication module is connected by serial ports with described central process unit.
Positive progressive effect of the present utility model is: the utility model have employed 4G communication module, and what the diagnostic data that OBD module can be obtained was real-time is transferred to background server, completes diagnosis function in time; By the position residing for architecture module determination vehicle; Can be surfed the Net by enable Wi-Fi functional realiey Wi-Fi by Wi-Fi module.OBD device provided by the utility model operation and easy to use, data acquisition timely and can carry out trouble diagnosing in real time.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model one preferred embodiment OBD device.
Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As shown in Figure 1, a kind of OBD device, comprises central process unit 1, OBD module 3,4G communication module 2,4G antenna 4, SIM 8, GPS module 5, GLONASS module 6 and architecture module 7.OBD module 3 is connected with central process unit 1 by OBD interface circuit 9, and 4G communication module 2 is connected with central process unit 1 by USB interface.4G antenna 4, SIM 8, GPS module 5, GLONASS module 6 and architecture module 7 are electrically connected with 4G communication module 2 respectively.Wherein, architecture module 7 for obtaining the location information at the current place of OBD device from nearest base station.OBD device also comprises Wi-Fi module 10 and Wi-Fi antenna 11, Wi-Fi antenna 11 is electrically connected with Wi-Fi module 10, and 4G communication module 2 is connected by SPI with Wi-Fi module 10.
In the present embodiment, when vehicle enter tunnel etc. cannot search GPS and GLONASS satellite-signal time, architecture module 7 can be used to position, thus can Real-time Obtaining vehicle position information.In addition, this 4G communication module 2 also connects Wi-Fi module 10 by SPI, by the enable Wi-Fi function of AT order, thus makes passenger on car can connect Wi-Fi Hotspot to surf the Net.Diagnostic process is carried out in real-time being sent on background server by 4G communication module 2 of the diagnostic data that OBD module 3 can obtain by central process unit 1, and the position location information that simultaneously also 4G communication module 2 can be got and temporal information etc. are sent on background server.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
