Brief description
A kind of installation of vehicle electron identifying read-write equipment with double antenna that Fig. 1 provides for this utility model one embodiment
Schematic diagram.
A kind of composition of vehicle electron identifying read-write equipment with double antenna that Fig. 2 provides for this utility model one embodiment
Structure chart.
Specific embodiment
As shown in figure 1, this gives the utility model proposes a kind of vehicle electron identifying with double antenna read
The installation example of write device, described vehicle electron identifying read-write equipment is by first antenna module (1), the second Anneta module (2), car
Detection module (3), control module (4) composition.Antenna assembly is arranged on one-lane surface by L bar, high apart from ground
Degree 5.5m-7m；First antenna module installation direction and 70 ° -75 ° of ground angle, antenna main lobe covers the first read-write region
(5)；Second Anneta module installation direction and 40 ° -45 ° of ground angle, antenna main lobe covers the second read-write region (6)；First
Read-write zone length 30m；Second read-write zone length 20m；Sail into read-write region speed less demanding in 150km/h, reading
The write device bit error rate 10-5Under the conditions of it is ensured that more than 5 times can be read and write.As shown in Fig. 2 control module controls first antenna module
Vehicle electron identifying in first read-write region is written and read, the car according to vehicle detection module detection after reading and writing unsuccessfully
Travel speed, the transmission power of setting the second Anneta module, control the second Anneta module and vehicle electron identifying to complete to read and write.
Described vehicle detection module, first antenna module, the second Anneta module are communicated by serial ports or network interface with control module.
Below the working method of the present embodiment is described, first antenna module is to the vapour entering in the first read-write region
Car electronic mark is written and read, and vehicle detection module carries out high-velocity scanning along vehicle heading to read-write region simultaneously, according to
The position of vehicle and driving speed information in scanning frame data acquisition scan region.Control module receives the first read-write region read-write
After the signal of failure, according to the Vehicle Speed information of vehicle detection module detection, the transmitting work(of setting the second Anneta module
Rate, and control the vehicle electron identifying in second Anneta module read-write the second read-write region.When vehicle detection module detects car
After sailing out of the second read-write region, the transmission power that control module is closed the second Anneta module or reduced the second Anneta module.
