Abstract
The present invention relates to a communication and control method for motor vehicles in the process of running, namely that license plates of motor vehicles are used as address codes which are inputted by keyboards in an address coding mode. The method realizes the communication and control between motor vehicles in the process of running through the transmission processing and the receiving processing of various signals and provides a good management method for the safe driving of motor vehicles and the control of special motor vehicles.
Description
A kind ofly in running, realize the method for communication and control about motor vehicles, signal transmission before and after being mainly used between driving vehicle and special vehicle (as police car) and crossing, the moving control in sentry post to vehicle.
Under the relatively more crowded situation of present traffic reason, to overtake other vehicles by force and the accident that gets into an accident constantly takes place, crossing, sentry post and police car require to stop and the rejector is also unrare, use the present invention to address the above problem.
The objective of the invention is to adopt mode with geocoding, the address code of the license plate number of each car as this car, adopt the method for wireless serial communication on this basis, all vehicles all can adopt the same frequency that transmits and receives, one car is launched other vehicles all can receive signal, the address code of address part in the signal processing system taking-up signal and own car is not relatively made invalidation if do not conform to then, then carries out control corresponding and operation demonstration when conforming to.
The present invention realizes in the following manner: be by transmitting and receiving communication and the control device that two parts constitute in the indoor installation of motor vehicle driving, with the trade mark of car as address code, when the communication that needs between car and the car, can be with the license plate number of required vehicle as address code, incoming traffic and control device, the address code that the other side receives behind the signal with own car compares, do not make invalidation if do not conform to, then carry out control corresponding and operation demonstration when conforming to, signal sends vehicle behind the signal that receives the backspace of the other side's vehicle, can carry out, thereby be implemented in communication and control in the vehicle operating process.
The present invention also can realize in the following manner: described communication and control device transmit and receive part by the serial port of computer, the higher-order of oscillation, modulation, amplify and the frequency-selecting amplification, demodulation, several parts of shaping pulse constitute, the keyboard of radiating portion adopts 4 * 5 matrix keyboards, have ten numerical keys and seven operating keys, take 9 I/O lines, wherein seven operating keys are respectively: (1) request of overtaking other vehicles, (2) permission of overtaking other vehicles, (3) request is stopped, (4) the special vehicle request is stopped, (5) order is stopped, and (6) force parking, and (7) scanning OPADD is forced parking.
Accompanying drawing 1 is an imagination schematic diagram of the present invention.
Accompanying drawing 2 is imagination schematic diagrams of the present invention.
Accompanying drawing 3 is imagination circuit diagrams of the present invention, below with reference to accompanying drawing the inventive method is done further narration:
The inventive method is to adopt the MCS-51 chip microcontroller as embodiment.Coding adopts binary number, and the position that tie point is linked to each other is decided to be " 0 ", and the position that does not connect is decided to be " 1 ", otherwise also can.For example the trade mark of certain vehicle is 3124, corresponding binary number is 00110000110100, then should with tie point first and second, four, seven, eight, nine, ten, 13,14 couple together, otherwise then tie point the 3rd, five, six, 11,12 should be coupled together.
Keyboard adopts 4 * 5 matrix keyboards, has ten numerical keys and seven operating keys, takies 9 I/O lines, and wherein seven operating keys are respectively: (1) request of overtaking other vehicles; (2) permission (answer that main front truck is made the back car) of overtaking other vehicles; (3) request stop situations such as () preceding vehicle missing packages; (4) the special vehicle request is overtaken other vehicles; (5) order is stopped; (6) force parking; (7) the scanning OPADD is forced parking (this situation will force all vehicle parkings, be applicable to mainly that the vehicle license plate number of being chased is unclear or just not have the situation of car plate at all).When being provided with on vehicle and crossing, sentry post, decide as required by these seven operating keys.
Control signal mainly is the demonstration to seven operating key indications, and every kind of signal all is aided with sound equipment when showing.Various signals can be distinguished by direction, the color of arrow lamp indication.Forcing stop sign then is by relay control ignition systems for vehicles, makes its parking.
Transmitting and receiving part is made up of several parts such as serial port, the higher-order of oscillation, modulation, amplification and the frequency-selecting amplification of computer, demodulation, shaping pulses respectively.Geocoding control signal by keyboard output is delivered to modulator by serial port in machine processing back as calculated, modulation is launched after amplifying, because of all vehicles all adopt the same frequency that transmits and receives, so the signal that the vehicle in coverage sends is all sent into computer by receiving unit.
Illustrate working condition: when needs are overtaken other vehicles, on numerical key, press desired license plate number, press " request of the overtaking other vehicles " key in the operating key simultaneously, at this moment, receive the vehicle that conforms to the address code of own car and promptly be carved with the arrow lamp that green makes progress and represent, simultaneously with sound equipment; Overtake other vehicles as agreeing, press " permission of overtaking other vehicles " operating key and give the person of overtaking other vehicles with indication; Other request is same, and whole communication process finishes.
Adopt method of the present invention, the back vehicle can propose required request to preceding vehicle, and the front car can send corresponding signal according to actual conditions; In addition, can realize the priority of special vehicle, as emissions such as police car, the fire fighting truck signal of overtaking other vehicles especially, other vehicle receives that this signal must give way in principle; And the control signal of forcing parking also can be sent in police car and crossing, sentry post, and corresponding vehicle is received behind this signal can play certain positive role with automatic cut-out point ignition system for controlling special situation.
In addition, the present invention can also adopt the device shown in the accompanying drawing 3 to realize, in accompanying drawing three, serial launching code and serial received decoding are finished by ED5026 and ED5027 respectively, 12D, 12E, the 12F that also can adopt Xiaoshan transistor J to produce finishes serial and sends and receive, and its operation principle is the same.
Claims (2)
1, the method of communication and control in a kind of motor vehicle running, it is characterized in that, be by transmitting and receiving communication and the control device that two parts constitute in the indoor installation of motor vehicle driving, with the trade mark of car as address code, when the communication that needs between car and the car, can be with the license plate number of required vehicle as address code, incoming traffic and control device, the address code that the other side receives behind the signal with own car compares, if do not conform to and do not make invalidation, then carry out control corresponding when conforming to and operation shows, signal sends vehicle after receiving the signal that the other side's vehicle returns, can carry out, thereby be implemented in communication and control in the vehicle operating process.
