Single bridge driving skill training and test scoring device and scoring method

Abstract

A unilateral bridge driving skill training and test scoring device, including satellite positioning and navigation system terminal receiver core modules A, B, embedded multimedia digital signal processor core module, data acquisition and equipment driver interface base plate four major parts; The core modules A and B all adopt the Beidou second generation+GPS dual-star four-frequency GNSS core module, and the core module A is connected with the antenna T1 for measuring the direction of the connection line from the position of the antenna T2 to the position of the antenna T1; the core module B and the The antenna T2 is connected to measure the coordinate value of the location of the antenna T2; the core module of the embedded multimedia digital signal processor is responsible for the processing of media signal data such as audio and video; the data acquisition and device driver interface board is provided with multiple interfaces, It is used to connect with external equipment; the device is an instrument suitable for the evaluation of driving skills in the training and examination process of the "passing a single-side bridge" project without fixed site facilities.

Description

technical field [0001] The invention relates to a testing device and scoring method for field driving skills of motor vehicle drivers, in particular to a driving skill training and testing scoring device and scoring method for unilateral bridges. Background technique [0002] The Ministry of Public Security's "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" has a test item called "passing the one-sided bridge"; Place (see Figure 1 of the attached drawing of this application specification, that is: the new standard "GA1029-2012 Motor Vehicle Driver Examination Site and Facilities Setting Specifications" currently being implemented Figure 9 ); in the place where the project of "passing a one-sided bridge" is located, in the past, in order to monitor whether the vehicle has "on the bridge" or "off the bridge", the following three methods are usually used: [0003] 1. Adopt the airflow boundary identification method: bury the airflow pipe under the ro...

AI Technical Summary

Problems solved by technology

[0006] These three methods have shortcomings. The first two methods have to wait for the road surface to harden before burying the relevant components. Therefore, the site construction is difficult, the construction period is long, the construction cost is high, and the maintenance is difficult and the maintenance cost is high;

[0007] The above latter method cannot know whether the vehicle should be on or off the bridge, and the position recognition device must be added to know which wheels should be on the bridge still under the bridge
