Referring to fig. 1, the multilane system includes a plurality of road side units 10 and a plurality of wireless transmission modules 30, and the road side units 10 and the wireless transmission modules 30 are in one-to-one correspondence; the road side units 10 are all provided with a main control module 20, the wireless transmission module 30 is connected with the main control module 20 by adopting a universal or special interface, and the wireless transmission module 20 can be a single device or an integrated device constructed with the road side units 10; the wireless transmission module 20 can communicate with each other in 433M, wifi, bluetooth or 5G; the roadside unit 10 further includes a radio frequency module (not shown in the drawings) and a communication module (not shown in the drawings), both of which are controlled by the main control module 20, and are respectively used for performing information interaction with a vehicle-mounted unit (not shown in the drawings) and a charging system (not shown in the drawings), so as to complete the whole ETC charging process; in this embodiment, the master control modules 20 of the multiple roadside units 10 are respectively connected to the corresponding wireless transmission modules 30, and the wireless transmission modules 30 enable the multiple roadside units 10 to realize communication networking, so that the multiple roadside units 10 can complete data sharing and clock synchronization, and time is accurately calibrated by using clock synchronization, so that the multiple roadside units can transmit microwave signals at the same time, and thus the risk of occurrence of neighbor interference is reduced; on the other hand, through data sharing, after the road side unit 10 on one lane transacts the target vehicle, the main control module 20 shares the transaction information to the main control module 20 of the road side unit 10 on the other lane through the wireless transmission module 30, so that the road side unit 10 on the other lane can be prevented from transacting with the target vehicle again, and the problems of neighbor interference and secondary transaction are avoided.

In the present embodiment, a vehicle that completes a transaction with the roadside unit 10 is referred to as a target vehicle. Then, after the one-way side unit 10 completes the transaction with the target vehicle, the corresponding transaction information is generated, since the main control module 20 of each lane road side unit 10 is connected to the wireless transmission module 30, the main control module 20 can send the transaction information to the main control module 20 of the adjacent lane through the wireless transmission module 30, and after the main control module 20 of the other lane receives the transaction information, the transaction information can be sent to another main control module 20 of the adjacent lane again, so as to ensure that the transaction information of the target vehicle is synchronized to all the main control modules 20. It should be noted that other data may be shared among the plurality of main control modules 20 in the above manner.

When the vehicle continues to move forward, if the OBU information is read by the RSU2 due to neighbor interference, the CTRL2 can match the OBU information in the shared information queue, i.e., control the RSU2 not to transact with it, and not send the OBU information to the LTS2, which can prevent neighbor interference and secondary transaction problems.

To realize clock synchronization of multi-lane microwave signals, a controller of one lane needs to be selected as a reference device, CTRL2 is used as a reference, CTRL2 acquires its own clock information T1 every 1s, and transmits T1 to WTM1 and WTM3 through WTM2, WTM3 and WTM3 respectively give the acquired T3 to CTRL3 and CTRL3, and time consumption of data from CTRL3 to the next controller through each wireless module is defined as T3, so that CTRL3 and CTRL3 set their own clocks to T3 + T3, CTRL3 simultaneously transmits clocks T3 + T3 to WTM3 through WTM3, and similarly, CTRL3 sets their time to T3 + T3 2, and at this time, clocks of 4 controllers can be synchronized, and set T72 +10ms, T3 +3 + T3 +3 + T3 + CTRL3 + T3 +3 + send out data as data for immediate transaction, and then sends out data after receiving CTRL3 ms and CTRL3 data. So as to ensure that the microwave signals of all RSUs are sent out at the same time, thereby reducing the risk of adjacent interference.

Another optional embodiment is that, a multilane system with a wireless transmission module is applied in a high-speed portal system, please refer to fig. 3, which specifically includes: road side units RSU1, RSU2, RSU3, RSU4, RSU5, and RSU 6; roadside unit controllers CTRL1 and CTRL2 wireless transmission modules WTM1 and WTM 2; portal system software PTS1 and PTS 2; the vehicle-mounted unit CPC card.

When the vehicle runs from the driving direction 1, CTRL1 controls RSU1, RSU2 and RSU3 to identify a CPC card of the vehicle, after identification is completed, CPC card information is transmitted to WTM2 through WTM1, after WTM2 transmits the information to CTRL2, a shared information queue is formed in CTRL2, when the vehicle continues to run forwards, if the CPC card is read by RSU4, RSU5 or RSU6 again, CTRL2 compares the CPC card information with data in the shared information queue, if matching is successful, the CPC card identification is not continued, and therefore reverse identification can be prevented.

Similar to embodiment 2, CTRL1 and CTRL2 can be clocked through WTM1 and WTM2, thereby ensuring that the RSUs in both directions emit microwave signals at the same time and also reducing the probability of reverse sign.
