Detailed Description
The utility model is further explained below with reference to the drawings.
As shown in fig. 1, the vehicle-mounted radio frequency positioning system of the utility model comprises a radio frequency signal transmitting device 1, a radio frequency signal reading device 2 and a processing host 3, wherein the radio frequency signal transmitting device 1 is fixed on two sides of a vehicle running path, the radio frequency signal reading device 2 and the processing host 3 are arranged in a vehicle, the radio frequency signal transmitting device 1 and the radio frequency signal reading device 2 communicate through radio frequency signals, and the radio frequency signal reading device 2 and the processing host 3 are connected through a serial communication wire.
In order to ensure that the radio frequency signal transmitting device 1 and the radio frequency signal reading device 2 can accurately sense and identify, and reduce identification errors, the radio frequency signal transmitting device 1 is arranged on two sides of a road, the ground on two sides of a straight road section is respectively arranged on the ground on two sides of the road at intervals of 10-15 m, and the road surface on two sides of a curve road section is respectively arranged on the road surface on two sides of the road at intervals of 4-5 m. The radio frequency signal reading devices 2 are arranged on the left side and the right side of the vehicle body.
The processing host 3 comprises a radio frequency signal transmitting device address module 3a, a calculating and positioning module 3b, a timing module 3c and an analysis and processing module 3d. The radio frequency signal transmitting device address module 3a, the calculating and positioning module 3b and the timing module 3c are all in signal connection with the analysis processing module 3d.
In order to facilitate the accurate positioning of the vehicle body position by the calculation positioning module 3b and reduce the operation amount, the address code of each radio frequency signal transmitting device 1 is unique, and the installation sequence on the road is consistent with the storage coding sequence in the radio frequency signal transmitting device address module 3 a.
When the vehicle runs near the radio frequency signal transmitting device 1, the radio frequency signal reading device 2 reads the address information radio frequency signal transmitted by the radio frequency signal transmitting device 1, and uploads the address information radio frequency signal to the analysis processing module 3d, and the analysis processing module 3d calls the address information pre-stored in the radio frequency signal transmitting device address module 3a to compare with the received address information to know the current theoretical position of the vehicle; the timing module 3c has the functions of accumulated timing and data storage, and the timing module 3c starts timing when the vehicle leaves the last radio frequency signal transmitting device 1 and stops timing when the vehicle reaches the next radio frequency signal transmitting device 1; the calculation and positioning module 3b can know the current actual position of the vehicle according to the accumulated time and the running speed of the vehicle recorded by the timing module 3c, and the analysis and processing module 3d judges whether the vehicle has longitudinal offset by comparing the current theoretical position of the vehicle with the current actual position of the vehicle.
Once the vehicle is laterally offset (as shown in fig. 2) during running, the vehicle scans the left radio frequency signal transmitting device and then scans the right radio frequency signal transmitting device, the timing module 3c records the time of receiving the left and right radio frequency signals, the calculation positioning module 3b can calculate the distance and the distance difference between the vehicle and the left and right radio frequency signal transmitting devices 1 according to the time, and the analysis processing module 3d can judge whether the vehicle is laterally offset according to the distance difference.
Once the longitudinal offset and/or the transverse offset of the vehicle exceed the allowable error range, the analysis processing module 3d gives an alarm to the vehicle-mounted computer, and the vehicle-mounted computer reminds a control room monitoring personnel to correct the vehicle through wireless network communication, so that the next accurate positioning is ensured.
The above-mentioned rf signal transmitting apparatus 1, rf signal reading apparatus 2 and processing modules in the processing host 3 are equivalent to those in the prior art for realizing the same functions or functions.
