I. Product Overview This product can effectively record the driver's speeding and fatigue driving and other illegal driving behavior, and thus the quality of work of the Division for effective monitoring of driving personnel, reduce traffic accidents, improve vehicle operating level. Therefore, the use of this product and supporting platform, can improve the company's overall management level and efficiency, reduce operating costs, improve economic efficiency and competitiveness of enterprises; objective and comprehensive vehicle traffic accident record of the various states and drivers The operation behavior, traffic accident analysis provides scientific basis to protect the legitimate interests of the parties to the accident, the traffic police to facilitate law enforcement and government regulation. Second, the main function of a display function (1) real-time display function does not operate in the case of tachograph display IC card code, current speed, real-time clock (vehicle traveling data recorder can provide YORK date and clock, in years , month, day, hour, minute, second, week display and record) (2) display and recording speed alarm when the vehicle speed exceeds a preset speed limit value, see the current speed alarm value and can be viewed in a continuous process of moving speeding total time. Vehicle traveling data recorder will be the first time issued a "tick, tick ..." sound the alarm to alert the driver to slow down. Drive recorder will record the driver code, driver's license number, speeding time to total time. (3) Display with recording drive recorder supports the display and recording of data, including: real-time clock, the driver code and the corresponding motor vehicle driver's license number, the accumulated mileage recent 360h within the sensor coefficient, driving speed within recent 360h, vehicle VIN number, license plate number, license plate classification, accident doubtful data, last two days of accumulated mileage, driving speed last two days, the fatigue driving record, speeding, records and other information. (4) Display driver fatigue and driver's record when the same four hours of continuous driving, driving recorder will display the words, please stop to rest 20 minutes, otherwise the recorder starts recording fatigue driving time and other information, the case of continuous driving over four hours when Under every five minutes once the alarm to remind the rest stop, if not stop, until the alarm once every five minutes. (5) display vehicle information and driver records management vehicle traveling data recorder with display and record the identity of the driver function, the driver needs before each drive, insert IC identity card to confirm their identity. (6) parameter query and set cars drive recorder supports a variety of ways to query and set parameters such as vehicle parameter query, IC card information query, the query speed record recently, recently fatigue driving records check, terminal settings, sensor coefficient setting the standard school When settings. Three, USB feature to download updates font, upgrades, downloads doubt accident data. Fourth, the print function to display the contents include: license plate number, license plate classification, the driver code, driver's license number, the print time, stop time, stop time from 15 minutes from the front to push the average speed of vehicles per minute (once per minute per hour were recorded 15 times) fatigue driving time (the last four consecutive fatigue driving record) five, power protection tachograph have power protection, power failure can save the data. Six technical parameters Working voltage terminal: DC9V ~ 36V Working current: <200mA (DC12V) Maximum current: maximum operating current terminal when printing <2000 mA Operating temperature: -20 ~ +70 ℃ Operating Humidity: 20 ~ 95% Dimensions: 158mmX97mmX55mm seven, adjusting parameter values ??1) If you do not speed, it can only require bright screen, it would only need to take three lines, positive and negative, and ACC (ACC and positive then together). 2) If the speed required to print out the words, but also take a speed pulse line (blue line), received the car speed pulse line. 3) transfer coefficient method: new features coefficient = [recorder existing feature coefficient * speed displayed on the recorder] / (number of car dashboard = 450 (logger system default) = auto run when the logger velocity values ??(such as 70km / h) = car ran several times when the value of the car on the dashboard (such as 80km / h) on the display according to the above formula and the value of new features have come out, = 450 * 70/80 = 393.75 (rounded 394), last modified logger system settings menu first seven of the pulse factor in item 5 in a 394. then again you're driving a car under test, for example, to 60km / h speed, run Look on the speed of the drive recorder is not also 60km / h, then tune successful, print out the speed of the correct speed, if not match, you will go by the above method to debug! know that the two values ??match up speed , generally about three times! (instructions say coefficients of 3.7 on the fourth page, above the equation, there is a menu for each tenth page description)
