Abstract
The utility model discloses a vehicle remote diagnosis system, which is characterized by comprising a power unit, an OBD2 interface unit communicated with a vehicle electronic control unit, a GSM module remotely communicated with the outside, a GPS module, an input and output module and a MCU unit for controlling the units. The system carries out remote diagnosis and monitoring by a GSM communication network and an OBD2 of a vehicle and enables a maintenance point to know vehicle conditions accurately in time so as to eliminate potential safety hazard in time.
Description
Technical field
The utility model relates to a kind of automobile detection system, is specially the automobile remote diagnostic system.
Background technology
Automobile in use some unpredictable faults occur through regular meeting; the ECU of most failure message automotive interior can preserve it get off; there are the fault or the operational factor of few part directly to tell the driver in the mode of demonstration or pilot lamp; more fault or undesired is to need the car owner to arrive could understand after maintenance store overhauls by the specialized maintenance personnel.Can not in time understand, grasp the problem that automobile occurs, and handle timely, will bring great potential safety hazard to the user of vehicle, bring great inconvenience also for the maintenance follow-up service of manufacturer simultaneously.
The utility model content
The purpose of this utility model is, overcome the deficiencies in the prior art, propose a kind of automobile remote diagnostic system, the OBD2 by gsm communication network and automobile carries out remote diagnosis, monitoring, make maintenace point understand vehicle-state in time, accurately, potential safety hazard is in time solved.
The technical solution adopted in the utility model is as follows: the automobile remote diagnostic system, comprise power supply unit, with the OBD2 interface unit of vehicle electronic control unit communication, gsm module, GPS module, input/output module, the MCU unit of control each several part unit with extraneous telecommunication; The OBD2 interface is by circuit conversion, and an end is connected with the MCU unit, and the other end is connected with the OBD2 joint of automobile; IO interface is connected with the MCU unit; The GPS module is connected with the MCU unit by connecting interface; Gsm module is connected with the MCU unit through circuit conversion; Power supply unit is connected with Vehicular battery, and is connected power supply with each unit.
Concrete, described power supply unit is connected with filtering circuit and mu balanced circuit.
Concrete, described IO interface comprises signal gathering unit and signal output unit.
Concrete, described IO interface is connected with hummer with pilot lamp.
The beneficial effects of the utility model are, it can automatic failure message with vehicle pass to the maintenance service personnel whenever and wherever possible, the maintenance personal also can according to circumstances send specific instruction to this equipment simultaneously, the running status of enquiring vehicle, so that judge whether the operating position of vehicle is normal, save car owner's the maintenance time.
Description of drawings
Fig. 1 is the system architecture synoptic diagram of the utility model embodiment.
Embodiment
Referring to Fig. 1, the automobile remote diagnostic system is made of 6 parts:
Power supply unit 1: be responsible for to the total system power supply, the power supply of input is carried out filtering, voltage stabilizing after, output meets the voltage of each unit demand, has the backup battery function simultaneously.
OBD2 interface unit 2: be the passage that native system and automobile ECU (electronic control unit) carry out communication, this interface mainly is the various communication Physical layers at automobile, with different physical layer signals, converts the signal that can receive, discern with MCU to; The conversion of signals of also MCU being sent simultaneously becomes the form of Physical layer compatibility.
Gsm module 3: realize and extraneous remote communicating function the platform that automobile information that native system received and gps data is sent to appointment by cell phone network.
GPS module 4: receiving satellite signal sends to MCU with the latitude and longitude information that the vehicle of native system has been installed and handles.
Input/output module 5: gather some outer triggering signals, as button signal; Export some indicator signals, as pilot lamp, hummer.
MCU unit 6: mainly finish control, carry out communication, image data by OBD2 interface and automobile ECU to the each several part unit; Gather the signal of input block, and carry out control corresponding output; Receive the satellite information of GPS module; Carry out communication with gsm module, the data of each unit of collecting are sent to platform by gsm module, exchange with platform information.
Wherein, the OBD2 interface is by circuit conversion, and an end is connected with the MCU unit, and the other end is connected with the OBD2 joint of automobile; IO interface is connected with the MCU unit; The GPS module is connected with the MCU unit by connecting interface; Gsm module is connected with the MCU unit through circuit conversion; Power supply unit is connected with Vehicular battery, and is connected power supply with each unit.
If running in the process of moving, vehicle presses danger button in the time of can't starting or kidnap, the maintenance service personnel that system will be at once sends to appointment with the positional information and the running state information of vehicle.
Remote diagnosis system of the present utility model has following characteristics:
1, the OBD2 diagnose interface that utilizes automobile itself to have obtains running state information and the DTC information of vehicle.
2, by GSM mobile handset network and extraneous formation communication, in time will in time send to by the information that OBD2 obtains in maintenance personal's hand, for understanding, judge that travel condition of vehicle provides real time information.
3, when having especially severe accident or fault to take place, the GPS module in time, accurately provides the position at vehicle place, convenient rescue.
4, the maintenance personal can regularly long-rangely carry out data analysis, fault diagnosis to vehicle.
