Abstract

Disclosed is a reaction testing instrument for the motor vehicle driver, which is composed of a single-board computer, a control board, a visual stimulus display screen, control buttons and a result output displayer. Because the reaction testing instrument adopts a microcomputer as the control centre, the test procedure and the test result can be output automatically; meanwhile, the reaction testing instrument fully associates the environment and the operation characteristics of the driver and has two manual control buttons and a foot-switch for giving answers to the various stochastic stimulus signals, and the human intervention is reduced. The utility model has the advantages of convenient operation and high accuracy.

Description

Reaction testing instrument

This utility model is a kind of electronic tester that detects automobile driver to the sharp degree in response time, and it also can be as the tester of other vocational adjustment inspections.

Response time is meant the time distance between reacting appears in stimulation, and the response time of testing is long more, represents that irritant reaction is blunt more to external world.Show from the statistics of vehicle accident, the driver make a strategic decision error be cause vehicle accident instead inferior to second reason of perception error.And the decision-making error has two aspects, the one, and decision error has promptly been taked the operation that should not take; The 2nd, the overlong time of decision-making has lost the opportunity of taking proper operation.So the decision-making capability of assess driver, for reducing vehicle accident, guarantee driving safety is significant.Testing response time is divided into simple reaction and selective response is tested two kinds.The simple reaction test presents single stimulation, requires tested personnel to make single reaction, and the selective response test then presents multiple stimulation, requires tested personnel to make different reactions to different stimulated.These two kinds of thorn conditions that can produce the reaction test instrument detect tested personnel to stimulating response time that produces and the ability that makes decisions.Known this class reaction test instrument is subjected to manual intervention bigger, operates also cumbersome.

This utility model has designed a kind of tester that is used for test machine motor-car time of driver's reaction, and this tester adopts microcomputer (single board computer) as control centre, in order to the processing and the output of control test process and test result.Fully combine the characteristics of motor-driven vehicle going environment and driver behavior in the tester design, guarantee that test is credible.

The component placement structure of this utility model tester as shown in Figure 1 and Figure 2.In the drawings: 1, tested button (two); 2, stimulate display aperture, 3, test result output; 4, print selector switch; 5, test selector switch; 6, reset button; 7, start button; 8, on and off switch; 9, tested foot switch; 10, panel; 11, visual stimulus generating means; 12, mains transformer.

The structure of tester such as block diagram 3 are among Fig. 3: A, microcomputer (single board computer); B, control panel; C, visual stimulus display screen; D, main examination control button; E, tested button; F, Output Display Unit as a result; G, power supply. Be that the utility model tester is by microcomputer (single board computer) A, control panel B, visual stimulus display screen C, main examination control button D, tested button E and as a result several parts of display F form. Microcomputer (single board computer) A is the control centre of tester, and the processing by control panel B is input to microcomputer A with the instruction of control button D, E, and resulting result is exported automatically by display F as a result. Specifically, tester microcomputer (single board computer) can be selected various 8 single board computers.

Panel B is a critical elements of the present utility model, its schematic diagram such as Fig. 4.A is 8 single board computers in Fig. 4, and K1 is the tested button 1 of left hand; K2 is the tested button 1 of the right hand; K3 is tested foot switch 9;K4 start button 7; K5 is test selector switch 5; K6 is a test/exercise switch; K7 is a reset button 6; R1～9 are resistance, and BG1-6 is an audion; F1-3 is a not gate; E1, E2 are positive source; L1-3 is a display lamp.The effect of panel B is: 1, press the instruction of microcomputer, make display screen present some visual stimulus.2, will lead examination by press button, the test of setting and the selection of exercise, the instruction of the selection of selective response and simple reaction and test beginning is transferred to microcomputer A.3, the information transmission that tested use button is replied is given microcomputer.

Visual stimulus display screen C is the visual stimulus generating means, and it is by the light of different colours (red, yellow, green), three-colour light-emitting pipe or the simple different graphic of being made up of solid color or different colours luminous tube.According to the instruction of test selector switch 5, microcomputer is controlled at visual stimulus display screen C and goes up the different stimulus signal of appearance, and tested personnel can be watched by the stimulation display aperture 2 on the tester panel, and these random stimulus signals are differentiated and decision-making for tested personnel.

The main examination control knob D of tester comprises test selector switch 5, reset button 6, andstart button 7 several shift knobs, main examiner person handles these buttons and sends instruction to microcomputer.

The tested control knob E of tester is made up of two manual tested buttons and a foot switch 9.Tester of the present utility model has designed two tested buttons 1 and 1 foot switch 9, and purpose is to make tested personnel simulate the natural environment of driving locomotive, and promptly both hands are handled a tested button respectively, with foot switch 9, the stimulation that occurs are reacted respectively.Display F can be by printout as a result, and charactron shows or display lamp is finished.Adopt printout to show test results in this utility model,test result exports 3 among Fig. 1, gets final product the test result of output print.

Embodiment

The microcomputer of reaction test instrument (single board computer) A can adopt TP801 single board computer, visual stimulus generating means to adopt the light of three kinds of more convenient different colours to form, and test result is exported with printer prints.The structure of the structure of tester such as Fig. 1, Fig. 2, panel such as panel schematic diagram are shown in Figure 4.

Characteristics of the present utility model are: 1, different colours light stimulates and to be presented in the same demonstration hole 2, thereby can avoid causing tested personnel only to be reacted in the position because the different stimulated position of appearing is different, strict test controlled condition. 2, tested replying adopts both hands by switch and floor push simultaneously, reflected the driver behavior characteristics. 3, owing to adopt microcomputer control, realization test process and test result are exported automatically, have reduced manual intervention, have made things convenient for operation, have improved testing precision.
