Car data, reference is chosen 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：One kind is manual time-keeping, and another is simple infrared sensor time set.The former can not be reduced
The error artificially brought, the latter is only suitable for dash, and the workload of personnel is added 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 of prior art is present and defect, are when the utility model offer one kind is based on automotive performance tester
Grating sensor control terminal in system.The utility model allows test result even to reduce the error that artificial origin brings
Games results are true, fair, just, triggered using grating sensor control terminal for timing, timing is given by trigger signal
System.
The utility model is adopted the technical scheme that：A kind of grating sensor tested based on automotive performance in timekeeping system
Control terminal, it is characterised in that：The terminal includes the grating sensor unit being made up of grating sensor；Connect by receiving end signal
The control unit that mouth and control module are constituted；The wireless transmission unit being made up of data radio station；By battery and charging module group
Into power subsystem and AC power supplies interface；Wherein AC power supplies interface is connected with charging module, and charging module is connected with battery,
Battery is connected with grating sensor, control module and data radio station respectively, grating sensor by receiving end signal interface with
Control module is connected, and control module is connected with data radio station.
Produced by the utility model is with beneficial effect：The design has that time delay is small, accuracy of timekeeping is high, transmission range
Remote the advantages of, it is adapted to the competition field of Various Complex landform.Simultaneously the design also have small volume, it is simple in construction, the spy such as be easily installed
Point, can meet outdoor application demand.
Brief description of the drawings
Fig. 1 is grating sensor setting principle schematic diagram in the utility model embodiment；
Fig. 2 is the utility model grating sensor control terminal structured flowchart.
Embodiment
The utility model is described further below in conjunction with drawings and examples：
As shown in Fig. 2 control terminal includes the grating sensor unit being made up of grating sensor；Connect by receiving end signal
The control unit that mouth and control module are constituted；The wireless transmission unit being made up of data radio station；By battery and charging module group
Into power subsystem and AC power supplies interface；Wherein AC power supplies interface is connected with charging module, and charging module is connected with battery,
Battery is connected with grating sensor, control module and data radio station respectively, grating sensor by receiving end signal interface with
Control module is connected, and control module is connected with data radio station.
As shown in figure 1, grating sensor unit includes transmitting terminal A and receiving terminal B, transmitting terminal A and receiving terminal B set 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
Gate sensor uses the PZ-G51N model sensors of KEYENCE companies, and transmitting terminal part A is furnished with electricity by lithium battery power supply
Display, when not enough power supply, can be charged, receiving terminal part B is powered by control cabinet, and signal is carried out in switching value form
Output., it is necessary to be proofreaded to transmitting terminal A and receiving terminal B gratings after device power, if receiving terminal B gratings all brighten, card
Bright transmitting terminal A has been aligned with receiving terminal B.When running car to grating sensor, receiving terminal B grating sensors go out.
Control unit, wireless transmission unit, power subsystem are concentrated in control cabinet.Control module is using NXP companies
LPC2114 chip controls, output interface is 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, 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
System just thinks there is timing trigger signal when blocking three groups of gratings, 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 signal is sent to by data radio station and is by control cabinet
System rear end reception device.Transmitting terminal grating is arranged in racing track side during match, and it is another that receiving terminal grating is arranged in racing track with control cabinet
Side.
