Abstract

The invention discloses a safety protection device for a driver to take a card at a station ramp and a working method for the safety protection device. Vehicle current position coordinates are compared with locating information of a wristwatch to obtain relative location of the wristwatch and a vehicle cab; and if the wristwatch is out of a control cabin, a brake system is started, the vehicle is kept to be in a braking state when a driver enters and exits a housing estate and the station ramp, and extends out a vehicle window to take the card, thereby effectively preventing the vehicle from losing control due to the fact that the driver presses on a pedal or loosens the brake by mistake.

Step 4, vehicle GPS gathers the position coordinate of Current vehicle, and the locating information of current vehicle position coordinate and watch contrasts by CPU treater, draws the relative position of watch and vehicle cab;
Step 5, CPU treater judges that watch is when vehicle cab outside, controls brake system start by CAN; CPU treater judges that watch is when vehicular drive chamber interior, controls brake system and closes, normal vehicle operation by CAN.
In described step one, when CPU treater identify vehicle motor rotating speed be zero or vehicle be normal speed travel time, CPU treater to micro controller system photos and sending messages, makes micro controller system cut out GPS locating module on watch by automobile wireless feedway.
Compared with prior art, the present invention is by contrasting the locating information of current vehicle position coordinate and watch, draw the relative position of watch and vehicle cab, if watch is outside driving compartment, then start brake system, step on brake when steerman turnover community, toll station's bayonet socket when leaning out vehicle window card taking, vehicle can be made to keep braking, effectively avoid because steerman steps on wrong pedal or releasing of brake and cause to lose control of one's vehicle.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present invention;
Fig. 2 is System Control Figure of the present invention;
Fig. 3 is that apparatus of the present invention open field of application schematic diagram.
[detailed description of the invention]
Below in conjunction with accompanying drawing, the present invention will be further described.
See Fig. 1 and Fig. 2, a kind of steerman is at the safety guard of station bayonet socket card taking, comprise watch and control unit, watch comprises GPS locating module 2, GPS locating module 2 connects micro controller system 3, micro controller system 3 connects wrist-watch radio receiving transmitting module 4, control unit comprises CPU treater 7, CPU treater 7 connects vehicle GPS 6 and automobile wireless transceiver module 5, CPU treater 7 can connect transmitting set tachogen and wheel speed sensors by CAN, and control brake system 8, CPU treater 7 by CAN conv connection CAN;
Wherein, CAN conv adopts CAN485 intelligent CAN conv, GPS locating module 2 adopts WTD-012X personal GPS steady arm, micro controller system 3 adopts STM32F101R6 micro controller system, CPU treater 7 adopts model to be the ARM9 treater of S3C2410, and wrist-watch radio receiving transmitting module 4 and automobile wireless transceiver module 5 all adopt nRF2401 single-chip wireless transceiver.
Steerman, in a method of work for the safety guard of station bayonet socket card taking, comprises the following steps:
Step one, CPU treater 7 gathers engine speed by CAN and running velocity contrasts, and obtains the running state of vehicle this moment;
When CPU treater 7 identify vehicle motor rotating speed be zero or vehicle be normal speed travel time, CPU treater 7 gives micro controller system 3 photos and sending messages by automobile wireless feedway 5, makes micro controller system 3 close GPS locating module 2 on watch;
Step 2, CPU treater 7 is transmitted by automobile wireless transceiver module 5, makes the wrist-watch radio receiving transmitting module in watch receive signal, is opened by micro controller system 3 control GPS locating module 2;
Step 3, GPS locating module 2 obtains the locating information of watch, and controls wrist-watch radio receiving transmitting module 4 by micro controller system 3 locating information is sent to CPU treater 7;
Step 4, vehicle GPS 6 gathers the position coordinate of Current vehicle, and the locating information of current vehicle position coordinate and watch contrasts by CPU treater 7, draws the relative position of watch and vehicle cab;
Step 5, CPU treater 7 judges that watch is when vehicle cab outside, controls brake system 8 start by CAN; CPU treater 7 judges that watch is when vehicular drive chamber interior, controls brake system 8 and closes, normal vehicle operation by CAN.
See Fig. 3, CPU treater 7 unlocking vehicle GPS6 obtains the coordinate position (a of vehicle, b), pre-enter the leading dimensions of operator's compartment: the length of operator's compartment is the distance g of steering wheel centre point to back of seat, the width of operator's compartment is the distance h of two front-wheels, in conjunction with the coordinate range calculating operator's compartment that vehicle coordinate position (a, b) just can be real-time, be respectively ( a + h 2 , b + g 2 ) , ( a + h 2 , b - g 2 ) , ( a - h 2 , b - g 2 ) .
The peripheral scope that hand stretches out by setting steerman is ( a - h 2 - 1.2 , b + g 2 + 0.8 ) , ( a + h 2 + 1.2 , b + g 2 + 0.8 ) , ( a + h 2 + 1.2 , b - g 2 - 0.8 ) , ( a - h 2 - 1.2 , b - g 2 - 0.8 ) , Unit is rice.
If the coordinate position of wrist-watch is within operator's compartment coordinate range, then think that the hand of steerman is in operator's compartment, so be not for further processing; If the coordinate position of wrist-watch is in outside the peripheral scope that hand stretches out by steerman, then think that steerman leaves vehicle.This situation not in limit of consideration interior, so be not for further processing.
If the coordinate position of wrist-watch is between these two scopes, dash area shown in Fig. 3, just think that at this moment steerman, when passing in and out community, toll station's bayonet socket, is just stretching out one's hand card taking.
During installation, first GPS is installed, STM32 series monolithic and radio receiving transmitting module, idle place's installation GPS locating module 2 in dial plate in steerman wrist-watch, adopt fine thread that a slice STM32 series monolithic 3 is installed again on wrist-watch GPS locating module 2 side, the wrist-watch radio receiving transmitting module 4 of wrist-watch is installed on STM32 series monolithic 3 side again, vehicle GPS 6 adopts microgroove bolt to be fixedly mounted on vehicle roof free time place, automobile wireless transceiver module 5 adopts microgroove bolt to be fixedly mounted on the indoor idle place of vehicular drive, CPU treater 7 is encapsulated in can, Signal transmissions is carried out by wire and the external world, CPU treater 7 installation site is positioned at idle place below hood of vehicle.
