Embodiment 1

[0188]Embodiment 1: Figure 13-1 shows a vehicle communication device. Microcontroller 1 and wireless transceiver 2 use a CC1010 single-chip radio frequency transceiver chip embedded with a microprocessor. Antenna circuit 3 uses two μPD5710TK antenna selection switches. Dual directional antennas that control the 90° directional angle. The driving positioner 4 uses a direction sensor: Honeywell two-axis magnetic sensor HMC1052L, which is a high-performance magnetoresistive sensor designed with a single component. The advantages of this design are Magneto-resistive chip, which can sense the magnetic field below 0.1 milligauss, each axis of the magneto-resistive sensor is configured as a 4-element Wheatstone bridge, which can convert the magnetic field into a differential output voltage, and the X-axis and Y-axis signals pass through The amplifier is input to the two input terminals AD0 and AD1 of the microprocessor for A / D conversion, and the driving direction parameters are obtai...

Embodiment 2

[0190] Example 2: Figure 14-1 shows the vehicle communication device. 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. The program controls the fixed transmission power to achieve fixed distance transmission; the driving positioner 4 adopts the HMR3100 compass module, and the driving position parameters are input through the UART interface. -Highway type / area code input key, C-driving lane / bit number input key, D-brake / password confirmation, E-fault / password modification, F-overtaking / vehicle number, G-parking / monitoring, H-fault / automatic Check, L reversing / car number, M-meeting / pause. The road type and 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 frequency hopping code can be used ...

Embodiment 3

[0192] Embodiment 3: Figure 15 shows the vehicle communication device, microcontroller 1 adopts AT90S8515, wireless transceiver 2 adopts AT86RF211, antenna circuit 3 adopts two μPD5710TK antenna selection switches to control dual directional antennas, fixed-distance transmitting circuit 5 adopts digital Potentiometer AD8402 adjusts the transmission power combined with the program control transmission power. The distance discrimination circuit 7 adopts the control register setting, measures the digital indication value of RSSI, and reads -105 ~ -40dB from the 29th ~ 24th bits of the status register (STAUS) Dynamic range, to achieve distance discrimination, with a 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. According to the speci...

Description

(1) Technical field [0001] The present invention relates to a radio transmission device and system, to an early warning device for vehicle driving and parking safety and a method for generating a contact signal, in particular to a device for state information transmission between vehicles and direct communication between vehicle drivers and the device and The communication of roadside devices, and the method by which they communicate with each other and generate signals, falls under the category of IST intelligent transportation systems. (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 driving. The limitations and shortco...
