This standard replaces GB / T 19056-2003 "vehicle traveling data recorder". Compared with GB / T 19056-2003, except for editorial modification, the main technical changes are as follows:

——Revised the introduction (see introduction, introduction of 2003 Edition);

——Revised scope (see Chapter 1, Chapter 1 of 2003 Edition);

——The definitions of vehicle traveling data recorder and continuous driving time are modified (see 3.1 and 3.5, 2003 version 3.1 and 3.3);

——The definitions of vehicle characteristic coefficient, upload and download are deleted (see 3.2, 3.5 and 3.6 of 2003 Edition);

——The definitions of pulse coefficient, driving start time, driving end time, continuous driving start time, continuous driving end time, overtime driving, the last two calendar days, positioning module, positioning accuracy and location information are added (see 3.2, 3.3, 3.4, 3.6, 3.7, 3.8, 3.10, 3.11, 3.12, 3.13);

——The general requirements are modified, and the requirements of integrated structure and front panel size are proposed (see 4.1 of 2003 Edition);

——The electrical components are modified and the performance requirements for connecting wires, connectors, fuses and other electrical components are put forward (see 4.2 of 2003 Edition);

——The function requirements are modified, the driving recording function and positioning function are added, and the safety warning function is added in the driving recording function (see 4.4.1, 4.4.2,;

——The data recording function is modified, including the requirements of driving speed record, position information record, installation parameter record, log record, etc., and the requirements of accident doubtful point record, driver identity record and mileage record are modified (see 2003 version of

4. 4. 3、 4. 4. 5) ;

——The data communication function is modified, the requirements of driver identification communication are added, and the requirements of data communication interface, RS232 serial communication and USB communication are modified (see, 4.4.8 of 2003 version);

——The display function is modified, and unified requirements for display, display contents and operation keys are put forward (see, 4.4.6 of 2003 Edition);

——The function of printing output is modified, and the mode and format of printing data are modified (see, 4.4.7 of 2003 Edition);

——In addition, performance requirements are added, including driving recording performance and positioning performance. The time recording error and speed in the original standard are recorded

Recording error and mileage recording error are included in the requirements of driving record performance (see 4.4.3, 4.4.4 and 5.5.3 of the 2003 Edition);

——The requirements for charts in data analysis software are modified (see 4.6, 4.5 of 2003 Edition);

——The temperature index of low temperature test in climate and environment adaptability test was modified (see 5.8.3 in 5.12.3 of 2003 Edition);

——The ESD immunity is modified (see 4.12, 5.12, 4.11 and 5.16 of 2003 Edition);

——The Radiated Immunity of radio frequency electromagnetic field (4.12 and 5.17 of 2003 Edition) is deleted;

——The transient immunity is increased (see 4.13, 5.13);

——Revised inspection rules (see Chapter 6, Chapter 6 of 2003 Edition);

——Installation position and wiring requirements are added (see 7.3 and 7.4);

——Revised appendix a-rs232 serial data communication protocol (see Appendix A, Appendix A of 2003 Edition);

——Appendix B - USB data storage format (see Appendix B) is added;

——Appendix C - data storage format of driver identification IC card is added (see Appendix C);

——Revised Appendix D - accident suspect data curve (see Appendix D, Appendix B of 2003 Edition);

——The references were revised (see references, 2003 Edition).
