Abstract
The present invention relates to a vehicle driving data recording method and a device, which can effectively monitor and save the data information of the controlled device and provide abundant and convenient operating data information for the vehicle electric-controlled system developing personnel. The technical solution of the invention is that the vehicle driving data recording method is characterized in that a master control chip reads the data information of a vehicle electric-controlled device and saves the data information in the storage unit.
Description
Technical field
The present invention relates to a kind of vehicle driving data recording method and device.
Background technology
Be accompanied by increasing of controlled vehicle-mounted electrical equipment, the controlled vehicle-mounted electrical system become become increasingly complex more and more various, it is difficult unusually that data analysis in the performance history also becomes, wherein the lasting down data of operation continuously of control panel nominal situation particularly are difficult to record, and this has brought great challenge for the fault analysis and the performance boost of control panel.
The vehicle-mounted drive recorder of present stage has following two kinds of forms usually:
1. unmanned driving road-condition recording unit
This equipment present stage is mainly utilized the running orbit of GPS technical notes vehicle, function singleness, the working condition of record controlled vehicle-mounted electrical equipment that can not be real-time.
2. the data recording equipment under the personnel operation situation is arranged
Under the situation that there are personnel involved, utilize multiple kinds, the working condition of the controlled vehicle-mounted electrical equipment under the record dynamic operation situation.But this data recording equipment is owing to personnel's restriction, the working condition of the record controlled vehicle-mounted electrical equipment that can not continue for a long time.The collection fund input of experimental data is huge, and the time is very long, has the working condition of many equipment not reflected really.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of vehicle driving data recording method and device, can effectively monitor the also data message of access controlled device, for the automobile electric control system developer provides abundant service data information easily.
The present invention is based on same inventive concept, have two independent technique schemes:
1, a kind of vehicle driving data recording method is characterized in that: the main control chip reads the data message of automobile electrically-controlled equipment, and data information memory is arrived storage unit.
The main control chip is connected with automobile electrically-controlled device talk by the CAN module, reads the data message of automobile electrically-controlled equipment based on the CCP agreement.
Can carry out online data based on the CCP agreement and refresh the control panel data variable that change will be read.
The main control chip is connected to the baud rate selector switch, can adjust the CAN transfer rate.
Storage unit adopts Flash Memory module.
The main control chip is connected to the external clock module, and this clock module is powered by rechargeable battery.
2, a kind of device of realizing aforementioned vehicle driving data recording method is characterized in that: the main control chip is connected with automobile electrically-controlled device talk through the CAN module, and the main control chip is circumscribed with storage unit.
The main control chip is connected to the baud rate selector switch.
The main control chip is connected to the external clock module, and this clock module is powered by rechargeable battery.
Storage unit adopts Flash Memory module.
The beneficial effect that the present invention has:
The present invention is specially adapted to the data recording of vehicle experimental development and vehicle trouble subsequent analysis, can overcome the vehicle bad working environment, under the situation of vehicle operating, can move automatically, whole duty need not artificial participation, storage data that can safe ready, data extract is convenient, has compatible preferably with respect to numerous control panels.
Data communication module of the present invention adopts the CAN communication, utilizes the high-strength noiseproof feature of CAN communication, can guarantee the transmission security of data: utilize the high transfer rate of CAN communication, guarantee the Large Volume Data transmission handling capacity of datalogger.
The present invention adopts jumbo Flash Memory as data storage cell, makes datalogger have better anti-vibration characteristic, guarantees the storage security of data.
The present invention can change the CAN transfer rate of main control chip by the baud rate selector switch, and the transfer rate of CAN can be changed from 0kbit/s to 500kbit/s, improves the hardware compatibility of datalogger.
The present invention adopt the CCP agreement as datalogger with the data communication agreement between the control panel.The data transmission carrier of CCP agreement itself is exactly the CAN communication, use the CCP agreement we can better utilization CAN communication numerous advantages.
Of the present invention also the support based on the online refresh function of CAN bus CCP protocol data, the life cycle of raising product can provide different data recording services at different control panel unit, improves the range of application of equipment, reduces the use cost of equipment.
The present invention can provide several data registering instrument data outputting communication interface, and the data of registering instrument collection can be carried out reading analysis by the product of ETAS and Vector company.
Description of drawings
Accompanying drawing is circuit theory diagrams of the present invention.
Embodiment
As shown in the figure, main control chip MCU is connected with automobile electrically-controlled equipment 2 communications through CAN module 1, the main control chip is circumscribed with storage unit 3, storage unit adopts jumbo FlashMemory module, be used for the storage defined data variable of DAQ in the control panel CCP agreement of surveying, just the datalogger information that will write down.
The main control chip is connected to baud rate selector switch (Dip Switch) 4, and this device is used for producing the digital input signals combination of various combination, and the modification to MCU CAN baud rate is provided.
The main control chip is connected to external clock module 5, and this clock module is by rechargeable battery 6 power supplies, and also not therefore power down of this clock module when datalogger cuts off the power supply is so module can provide a permanent clock coordinates.
Main control chip MCU reads the data message of automobile electrically-controlled equipment based on the CCP agreement, and the data information memory of control panel waits the subsequent extracted analysis of pending data to jumbo flash memory.Based on the CCP agreement, the present invention also can carry out online data and refresh, and at different control panels, the control panel data variable that change will be read also can carry out firmware upgrade to the performance and the function of driving data recording equipment simultaneously.
