Fig. 4 is a schematic diagram of an electronic toll collection method according to an embodiment of the present invention, and please refer to fig. 4, which is an exemplary illustration of a four-lane toll collection system, where a first lane corresponds to RSU1, toll software 1 and an interception device 1, a second lane corresponds to RSU2, toll software 2 and an interception device 2, a third lane corresponds to RSU3, toll software 3 and an interception device 3, and a fourth lane corresponds to RSU4, toll software 4 and an interception device 4, and 4 roadside units may be coplanar, non-coplanar, unidirectional, or anisotropic. Specifically, under the condition that 4 road side units are coplanar, the centralized control module controls the 4 road side units to simultaneously transmit BST data carrying lane marks by using the same parameters of channels, power and the like; under the condition that the 4 road side units are not coplanar, the centralized control module can control the 4 road side units to simultaneously send BST data carrying lane marks by using parameters such as different channels, different powers and the like according to the calculation of a specific use scene; in other embodiments, the centralized control module may control the 4 rsus to transmit BST data carrying lane markers using the same channel under the condition that the 4 rsus are not coplanar and in the same direction; when the 4 road side units are not coplanar and in different directions, the 4 road side units can be controlled by the centralized control module to use different channels to transmit BST data carrying lane marks.
Alternatively, the intercepting device in this embodiment may be a railing machine, a rod machine, a barrier gate, an electric retractable door, or other devices that can be used to intercept the passing of vehicles, which is not limited in this embodiment.
If the vehicle-mounted unit OBU2 enters the RSU2, the vehicle-mounted unit OBU2 replies reply data carrying the mark data corresponding to the lane mark, and because 4 road side units simultaneously transmit the data, the vehicle-mounted unit OBU2 can only receive the BST data carrying the lane mark issued by the road side unit corresponding to the road; if the RSU2 receives reply data replied by the on-board unit OBU2, the reply data is sent to the centralized control module, the centralized control module matches and judges the mark data in the reply data with the lane mark of the RSU2, the matching is successful, the lane where the on-board unit is located is determined to be the RSU2 lane, and the centralized control module guides the RSU2 to continue to conduct transaction with the on-board unit. The centralized control module controls the road side units to send data at the same time, and because the data are sent at the same time, the data received by the vehicle-mounted unit have the signal strength difference due to the distance, so that the vehicle-mounted unit preferentially receives the data of the strongest signal, namely the data sent by the road side unit of the lane, and the neighbor interference is reduced.
If the RSU1 receives reply data replied by the on-board unit OBU2, the reply data is sent to the centralized control module, the centralized control module judges that the mark data in the reply data is matched with the lane mark of the RSU1, the matching fails, the centralized control module determines that the mark data is successfully matched with the lane mark of the RSU2 according to the mark data in the reply data, then the centralized control module controls the transaction between the RSU2 and the on-board unit OBU2, and the RSU1, the RSU3 and the RSU4 can continue to simultaneously send BST data with lane marks and retrieve and awaken the on-board unit on a corresponding lane.
If the RSU1 and the RSU2 both receive reply data replied by the on-board unit OBU2 and upload the reply data to the centralized control module, the centralized control module determines that the on-board unit OBU2 and the RSU2 are successfully matched through matching, instructs the RSU2 to continue trading with the on-board unit OBU2, and instructs the RSU1, the RSU3 and the RSU4 to continue to transmit BST data carrying lane marks at the same time.
If 2 vehicle-mounted units OBU1 and OBU2 enter into transaction areas of RSU1 and RSU2 respectively, RSU1 and RSU2 send received reply data replied by the vehicle-mounted units to the centralized control module, the centralized control module determines lanes where the vehicle-mounted units OBU1 and OBU2 are located through matching, the corresponding road-side units are guided to conduct transactions, data interaction is conducted with the charging software, the charging software interacts data of different vehicle-mounted units with the centralized control module simultaneously according to vehicle-mounted unit information or other information, and the centralized control module is guided to control the RSU1 and the RSU2 to complete transactions with the OBU1 and the OBU2 respectively.
Optionally, in other embodiments, the centralized control module may also control the RSU1, the RSU2, the RSU3, and the RSU4 not to send data at the same time, when one or more of the road side units receive reply data replied by the on-board unit, send the reply data to the centralized control module, and the centralized control module performs joint positioning or other methods on the received information of the on-board unit to determine the position of the on-board unit, so as to determine the lane where the on-board unit is located. Specifically, the vehicle-mounted unit can be positioned by the positioning road side unit, the positioning road side unit can detect the position of the vehicle on the vehicle-mounted units of 1 or more lanes, and transmits the positioning information to the road side units of other lanes in a wireless or wired manner, and the positioning road side unit can be installed in the lanes or other positions of a toll station, such as a safety island and the like. And matching the lane mark data with the lane where the vehicle-mounted unit is located, if the matching is successful, guiding the corresponding road side unit and the vehicle-mounted unit to continuously finish the transaction, and continuously sending data for awakening the vehicle-mounted unit by other road side units and retrieving the vehicle-mounted unit.
Optionally, in other embodiments, the multiple rsus may be in communication connection with each other, and the mutual communication connection between the rsus may be used to implement clock synchronization and data sharing between the rsus, and through communication networking between the rsus, transaction information of different rsus may be synchronously shared and obtained, and the time may be accurately calibrated by using clock synchronization, so that data information may be synchronously transmitted at an accurate time. Specifically, the road side units send synchronization information at intervals with preset time length, so that the effect of time synchronization among the road side units is achieved, and the road side units synchronously send data information to the vehicle-mounted unit according to the preset time length. On one hand, the target vehicle is not interfered by the transaction information sent by the road side unit of the adjacent lane when receiving the transaction information, and the generation of adjacent interference is effectively reduced; on the other hand, through data sharing, the road side unit on one lane shares the verification information to other lanes after the target vehicle is traded, and the other lanes are prevented from trading with the target vehicle again, so that repeated charging is avoided.
In addition, in other embodiments, the number of the centralized control module and the charging software may be set to one, and one centralized control module is connected with one charging software and a plurality of road side units and is used for synchronously acquiring data of the plurality of road side units, implementing data sharing, and processing the acquired data, so that transaction information of the plurality of road side units and the vehicle-mounted unit can be shared to one centralized control module, and one centralized control module controls the plurality of road side units uniformly and controls the transaction information of the plurality of road side units to be transmitted to one charging software, so as to complete a transaction flow. Meanwhile, clock synchronization and information sharing of the road side unit can be achieved through unified control of the centralized control module, and therefore the problems of neighbor interference and repeated charging are avoided.
