Owing to adopting technique scheme, the present invention's motorist driving efficiency practises guidance and examination scoring apparatus and the exercise of motorist driving efficiency is taught and the method for marking of taking an examination has following beneficial effect for realizing:

1. improved the reliability to examination vehicle physical location measurement data, to judge more quickly and accurately whether the vehicle body of examination vehicle has the situation of outlet:

1. the machine vision that apparatus of the present invention consist of multimedia video processor DSP and ccd video camera or global position system in conjunction with digitizing switch amount collector, to vehicle driver car steering technical ability, exercise is taught and examination scoring, is jointly to realize with the collaborative work of the software moving in built-in Linux operating system or windows CE operating system by the hardware of operation built-in Linux operating system or windows CE operating system; Therefore, reduced and assisted by the prestige of virus infraction, improved the stability of application system;

2. apparatus of the present invention are connected with long-range PC watch-dog by the wireless communication module being connected with RS-232 interface 208 or RS-485 interface 207 or Ethernet interface 204 interfaces, make remote monitoring person monitor at any time the examination process of examination vehicle and examinee's operational circumstances; Utilize vehicle physical displacement data, in conjunction with the vehicle speed signal of vehicle self, conclude more accurately actual travel speed and the direction of examination vehicle; Make the scoring of driver's driving efficiency judge comparatively fast with accurate;

3. utilize global position system A interface and global position system B interface, can access GPS of America global position system and Chinese big-dipper satellite positioning system simultaneously, realization backups each other or each other with reference to two kinds of mode of operations, when a set of global position system lost efficacy therein, can utilize the another set of global position system location of continuing; In the time that two cover global position systems are all normally worked, reference mutually, carries out error correction; Use relative coordinate system simultaneously, in conjunction with the measurement data of global position system, formulate the vertical projection curve data of vehicle body corner angle to surface level, can identify fast the whether phenomenon of outlet of vehicle body, therefore, greatly improve the reliability of examination vehicle physical location measurement data, to judge more accurately whether the vehicle body of examination vehicle has the situation of outlet, the scoring of driver's driving efficiency has been judged comparatively fast with accurate simultaneously.

2. improved the integrated level of mobile unit function, reduced client and bought and maintenance cost.

1. apparatus of the present invention are that a driving efficiency using for driving efficiency training vehicle and examination vehicle that can not rely on remote control center or host computer and work alone is assisted automatic scoring device; In the time having host computer or control center to intervene, this device just can be used for to the take an exam automatic scoring of process of driver; In the time not having host computer or control center to intervene, the school grade that requirement that can mock examination process is carried out driving efficiency to driver's learning process is marked, and improves student's learning efficiency, reduces instruction cost.When there is connected remote control center, host computer or network communication fault in exercise or examination process time, therefore ongoing exercise or examination process can not interrupt, and can be automatically in the time that communication recovers normal repay to host computer or control center the corresponding data having lacked.

2. make training or examination process that a monitoring PC of remote control center can more than two and two vehicle of integrated management, save human and material resources and expenses.

3. reduce upgrading, the improvement expenses in existing subject two and subject three examination equipment and place, can improve largely the service efficiency of place, vehicle and computer system.

4. to using place, vehicle and the computer system of this device, more convenient in system maintenance, faster.

3. the upgrading of apparatus function and aspect of performance is all more convenient, also can not cause the similar scoring apparatus of overlapping investment even if there is new Examination Rule to put into effect:

1. due to the Operation and management platform that has used the signal condition of operating system and unification, standard and interface between software and hardware as application software, therefore the upgrading of function and aspect of performance is all more convenient;

2. adopt the hardware and software platform that adapts to multiple interface between software and hardware simultaneously, reduce required sensor, signal wire and other additional firmware in retrofit process, reduce total repacking workload, reduce total repacking cost;

3. for different examination vehicles, work out the signaling interface form of unified standard, facilitate upgrading and other maintenance of software;

4. for different examination vehicles, adopt the special wire harness with unified interface standard, reduce the construction and maintenance cost of whole system;

5. replace place real-time recording data with real-time vehicle running track data accurately, can reduce the take an examination memory space of process data data of examinee, reduce the desirability of the performance of automatic Computer Examination Evaluating System to hardware.

4. reduce the requirement of mobile unit to power supply index and shutdown process, improved the stability of system software:

Apparatus of the present invention utilization adapts to the DC-DC supply convertor 215 of the wide voltage input of DC 8-36V that examination vehicle mains voltage variations is large, after examination vehicle starts, can power and charge to vehicle-mounted storage battery for subsequent use to mobile unit with the electric power of automobile current generator, thus the power-on time that extends vehicle-mounted storage battery for subsequent use; Secondly because apparatus of the present invention have been used the embedded OS being installed in nonvolatile memory, and the parameter of start-up course is fixed, dynamic data is independent and do not do abnormal shutdown and process, even if therefore frequent power-off shutdown can not cause the unstable of system and application software yet, from the appearance the result that, each start powers on is all the same.

Below, in conjunction with the accompanying drawings and embodiments the present invention's motorist driving efficiency exercise is taught and examination scoring apparatus and the exercise of motorist driving efficiency is taught and the technical characterictic of the method for examination scoring is further described for realizing.
