Problems solved by technology

[0010] Chinese Patent Publication No. CN5008214, the application titled "Vehicle Signal Series Remote Control Method and Alarm Braking Anti-collision System", adopts "the front and rear vehicles sequentially transmit signals in series, and successively receive, alarm, display and brake". Although the direct communication between vehicles has passed by, there are advantages and some problems. Among them, "the regulation of the driving direction of the vehicle: the driving direction of each expressway is divided into uplink and downlink. For example, the Shanghai-Nanjing Expressway It is stipulated that the direction of Shanghai is up, and the direction of Nanjing is down. When the vehicle is going up, the driver should switch on the power supply of the uplink circuit, and when the vehicle is going down, the driver should switch on the power supply of the downlink circuit. The method of driving direction lacks universal applicability. First of all, naming highways with the abbreviations of starting and ending places does not conform to international practice and cannot be used abroad; From now on, it will be gradually transitioned according to international practice, and will be named in the form of numbers, such as the Shanghai-Nanjing Expressway, numbered A11. Secondly, there are a large number of roads that are not named according to the starting and ending locations, such as the outer ring road, the third ring road of the ring expressway, and the national highway 312 , Zhongshan Road, Bayi Avenue, etc., how to determine the up and down? Not to mention that there are ordinary roads that are not familiar with or can’t even call out the road names. The method of setting the driving direction by the driver has great potential safety hazards. Hand miscellaneous is also inevitable to make mistakes, in case one vehicle sets the wrong direction, it will cause a road-wide disaster to the communication of all oncoming vehicles.
They are only limited to anti-theft alarms, and cannot be used to prevent hijacking and robbing cars. In particular, they have not realized one machine with multiple functions, which can be used to prevent car theft and carjacking, and can be used for driving safety, providing drivers with double insurance for life and property.

Embodiment 1

[0193] Example 1: Figure 13-1 The vehicle communication device is shown, the microcontroller 1 and the wireless transceiver 2 adopt CC1010 single-chip radio frequency transceiver chip with embedded microprocessor, and the antenna circuit 3 adopts two μPD5710TK antenna selection switches to control the dual orientation of the 90° directional angle Antenna, driving positioner 4 adopts direction sensor: Honeywell two-axis magnetic sensor HMC1052L, it is a high-performance magnetoresistive sensor designed with a single component, the advantage of this design is the magnetoresistive chip, it can sense For magnetic fields below 0.1 milligauss, each axis magnetoresistive sensor is configured as a 4-element Wheatstone bridge, which can convert the magnetic field into a differential output voltage. The X-axis and Y-axis signals pass through the amplifier and input to the two microprocessors. The two input terminals AD0 and AD1 carry out A / D conversion, obtain the driving direction par...

Embodiment 2

[0195] Example 2: Figure 14-1 The vehicle communication device is shown, the microcontroller 1 uses Atmega161, the wireless transceiver 2 uses nRF905, and the antenna circuit 3 uses a μPD5710TK antenna selection switch to control an omnidirectional antenna and a directional antenna. Distance transmission; driving positioner 4 adopts HMR3100 compass module, input driving position parameters through UART interface, keyboard number keys 0~9, double function key comparison table: A-driving / parking switch, B-highway type / area code input key, C-driving lane / position number input key, D-brake / password confirmation, E-fault / password modification, F-overtaking / vehicle number, G-parking / monitoring, H-fault / self-inspection, L reversing / vehicle number, M-meeting / pause. The type of road and the driving lane can be input through the keyboard, so that the microprocessor 1 can synthesize a complete communication code. The working frequency of nRF905 can be programmed, and the communication c...

Embodiment 3

[0197] Example 3: Figure 15 The vehicle communication device is shown, microcontroller 1 uses AT90S8515, wireless transceiver 2 uses AT86RF211, antenna circuit 3 uses two μPD5710TK antenna selection switches to control dual directional antennas, fixed-distance transmission circuit 5 uses digital potentiometer AD8402 to adjust the transmission power Combining with the program to control the transmission power, the distance discrimination circuit 7 adopts the control register setting, measures the digital indication value of RSSI, and reads the -105~-40dB dynamic range from the 29th to 24th bits of the status register (STAUS) to realize the distance discrimination , has a very good safety distance warning function, without the cost. AT86RF211 can program the transmitting and receiving frequency. The special control direction setting switch is composed of CS3075 self-locking Hall switch and red and green light-emitting diodes LED2 and LED3 for detecting the switch state. Accordi...

Description

(1) Technical field [0001] The present invention relates to a radio transmission device and system, to an early warning device and a communication method for vehicle driving and parking safety, and in particular to a device for state information transmission between vehicles and direct communication between drivers of vehicles and the connection between the device and road The communication between the side communication device and the roadside communication system, as well as their communication methods, belong to the category of IST intelligent transportation system. (2) Background technology [0002] Direct communication between vehicles is not an unfamiliar problem. The traditional car horn and light signal system, which is still in use so far, is the simplest direct communication between cars. Communication, with simple structure and low cost, is suitable for occasions with low vehicle speed, simple roads and low traffic volume, and plays an important role in safe drivi...
