Background technology
At present, all can test through testing performance index before automobile dispatches from the factory, in order to test automotive performance, react most true
Car data, choose reference for what consumer provided most worthy, if also having emerged in large numbers the big event of dry type.It is common at present
Timing means have two kinds：A kind of is manual time-keeping, and another kind of is simple infrared sensor time set.The former cannot be reduced
The error artificially brought, the latter are only suitable for dash, and the workload of personnel is increased during marathon, it is impossible to accomplish be
The automation mechanized operation on system backstage.
The content of the invention
In view of the problem and defect of prior art presence, present invention offer is a kind of to be tested in timekeeping system based on automotive performance
Grating sensor control terminal.The present invention allows test result even games results to reduce the error that artificial origin brings
Truly, it is fair, just, triggered for timing using grating sensor control terminal, timekeeping system is given by trigger.
The present invention is adopted the technical scheme that：A kind of grating sensor control tested in timekeeping system based on automotive performance
Terminal, it is characterised in that：The terminal includes the grating sensor unit being made up of grating sensor；By receiving end signal interface and
The control unit of control module composition；The wireless transmission unit being made up of data radio station；It is made up of accumulator and charging module
Power subsystem and AC power supplies interface；Wherein AC power supplies interface is connected with charging module, and charging module is connected with accumulator, electric power storage
Pond is connected with grating sensor, control module and data radio station respectively, and grating sensor is by receiving end signal interface and control
Module connects, and control module is connected with data radio station.
Produced by the present invention with beneficial effect it is：The design has that time delay is little, accuracy of timekeeping is high, long transmission distance etc.
Advantage, is adapted to the competition field of Various Complex landform.The features such as the design also has small volume, simple structure, is easily installed simultaneously, can
Meet outdoor application demand.
Description of the drawings
Fig. 1 is grating sensor setting principle schematic diagram in the embodiment of the present invention；
Fig. 2 is grating sensor control terminal structured flowchart of the present invention.
Specific embodiment
Below in conjunction with drawings and Examples, the present invention will be further described：
As shown in Fig. 2 control terminal includes the grating sensor unit being made up of grating sensor；By receiving end signal interface and
The control unit of control module composition；The wireless transmission unit being made up of data radio station；It is made up of accumulator and charging module
Power subsystem and AC power supplies interface；Wherein AC power supplies interface is connected with charging module, and charging module is connected with accumulator, electric power storage
Pond is connected with grating sensor, control module and data radio station respectively, and grating sensor is by receiving end signal interface and control
Module connects, and control module is connected with data radio station.
As shown in figure 1, grating sensor unit includes that transmitting terminal A and receiving terminal B, transmitting terminal A and receiving terminal B arrange three altogether
Group grating sensor；The grating sensor of transmitting terminal part A is respectively grating sensor A1, grating sensor A2 and grating sensing
Device A3；The grating sensor of receiving terminal part B is respectively grating sensor B1, grating sensor B2 and grating sensor B3.Light
PZ-G51N model sensor of the gate sensor using KEYENCE companies, transmitting terminal part A is by lithium battery power supply, and is furnished with electricity
Display, when not enough power supply, can be charged, and receiving terminal part B is powered by control chamber, carries out signal with switching value form
Output.After device power, need to proofread transmitting terminal A and receiving terminal B gratings, if receiving terminal B gratings all brighten, card
Bright transmitting terminal A is aligned with receiving terminal B.When running car is to grating sensor, receiving terminal B grating sensors go out.
Control unit, wireless transmission unit, power subsystem are concentrated in control chamber.Control module is using NXP companies
LPC2114 chip controls, output interface are RS232 modes.Wireless transport module contains Science and Technology Ltd. using Shenzhen China
WD889 wireless digital broadcasting stations, transmission power 5W, interface rate 9600bps, aerial speed 2400bps.When receiving terminal grating sensing
When device is blocked, control module is judged, if thinking this signal effectively, sends the data to data radio station, and data radio station leads to
Cross antenna and transmit data to timing rear end.Power module provides 12V voltages by lead-acid accumulator, is judged by electric-quantity display device
The state of battery electric quantity, when battery electric quantity is not enough, is charged using external AC-220V power supplys.
Sensor section is made up of transmitting terminal and receiving terminal, and altogether containing three groups to penetrating grating sensor, automobile only has simultaneously
When blocking three groups of gratings, system just thinks there is timing trigger, can so avoid because of small size object（As slungshot, fallen leaves,
Butterfly etc.）The false triggering caused through one group of grating.When vehicle stops grating, on-off model output is had.
After the useful signal that grating is transmitted is received, corresponding trigger is sent to and is by data radio station by control chamber
System rear end reception device.During match, transmitting terminal grating is arranged in racing track side, and it is another that receiving terminal grating is arranged in racing track with control chamber
Side.
