a plurality of traffic cones 4 are placed at positions, corresponding to the third marking lines 13, on the side edges of the road, and the number of the traffic cones 4 is placed according to actual needs;
the traffic cone 4 comprises a cone body 41, a near field communication unit arranged at the top of the cone body 41, a first control unit 43 arranged in the cone body 41, a battery pack 44 for supplying power, a magnetic sensor 45 arranged at the bottom of the cone body 41 and a displacement mechanism for driving the traffic cone 4 to move; the near field communication unit is used for checking the distance between the adjacent traffic cones 4, and the magnetic sensor 45, the displacement mechanism and the near field communication unit are connected with the first control unit 43;
the road traffic management system further comprises a remote server for issuing control instructions to the first control unit 43. The first control unit 43 is communicatively connected to a remote server via a communication module.
Specifically, in this embodiment, the remote server establishes a rectangular coordinate system with the intersection point of the first marking 11 and the third marking 13 as the origin, the direction parallel to the first marking 11 as the transverse direction and the direction parallel to the third marking 13 as the longitudinal direction, and establishes the rectangular coordinate system by using the marking on the road, so that the established rectangular coordinate system is closer to the traffic cone 4 in use scene, and the control is simpler.

The RFID tag 421 is preferably an active RFID tag 421, which is transmitted over a longer distance to ensure communication between adjacent traffic cones 4. The RFID tags 421 and the RFID readers 422 are alternately distributed in turn along the circumferential direction, so that when the traffic cone is placed in different directions, information communication between adjacent traffic cones 4 can still be maintained. In this embodiment, the first control unit 43 can determine the distance between the first control unit and the adjacent traffic cone 4 according to the received second radio frequency signal, and determine whether to control the displacement mechanism to work according to the determination result. Specifically, the first control unit 43 of the traffic cone 4 controls the RFID reader 422 to transmit a first radio frequency signal to one of the adjacent traffic cones 4, after the RFID tags 421 of the adjacent traffic cones 4 sense the first radio frequency signal, and reversely scatter a second radio frequency signal according to the first radio frequency signal, the RFID reader 422 of the traffic cone 4 receives the second radio frequency signal backscattered by the adjacent traffic cone 4, and feeds back the second radio frequency signal to the first control unit 43, and the first control unit 43 determines the actual distance D between the two according to the received second radio frequency, at this time, the first control units 43 of the other traffic cones 4 control the respective RFID tags 421 and RFID reader 422 to be in an inactive state so as not to generate interference; because the intensity of the first radio frequency signal is attenuated along with the propagation distance, the energy obtained after the RFID tag 421 receives the first radio frequency signal is proportional to the intensity of the first radio frequency signal, and because the intensity of the second radio frequency signal is proportional to the energy input by the RFID tag 421, the RFID reader 422 can obtain the actual distance D between the adjacent traffic cones 4 according to the second radio frequency signal after receiving the second radio frequency signal, and if the actual distance D exceeds the error range, the first control unit 43 controls the traffic cones 4 to move and adjust until the actual distance D is within the error range.
In this embodiment, when the magnetic sensor 45 corresponds to the first marking 11, the second marking 12 or the third marking 13 in the process of placing the traffic cone 4, the magnetic sensor 45 generates an induction signal and sends the induction signal to the first control unit 43, and the first control unit 43 determines the current position of the traffic cone 4 according to the induction signal; since the magnetic field intensities generated by the first, second and third markings 11, 12, 13 are different, the traffic cone 4 can be determined at the first, second or third markings 11, 12, 13 by the magnetic field intensity sensed by the magnetic sensor 45.
In the actual traffic management process, as shown in fig. 6, the positions of the traffic cones 4 corresponding to the third marking 13 are placed in the area outside the first marking 11, and a charging station for charging the traffic cones 4 can be set in the area, so as to provide continuous charging requirements for the traffic cones 4;
when an external traffic control center needs to split traffic at the intersection, the external traffic control center sends traffic splitting requirements to a remote server, the remote server determines splitting areas according to the traffic splitting requirements, determines the number of traffic cones 4 and the coordinate information of the traffic cones 4 according to the splitting areas, and marks the traffic cones 4 according to the required number;
the remote server sends a first control instruction to the first control unit 43 of each traffic cone 4, where the first control instruction includes the number of traffic cones 4, the number of labels and the coordinate information of the placement of the traffic cones 4, and if the number of traffic cones 4 is 7, the first control instruction is sequentially labeled as a traffic cone 1, the coordinates are (X1, Y1), a traffic cone 2, the coordinates are (X2, Y2), a traffic cone 3, the coordinates are (X3, Y3), a traffic cone 4, the coordinates are (X4, Y4), a traffic cone 5, the coordinates are (X5, Y5), a traffic cone 6, a traffic cone 7, and the coordinates are (X7, Y7); the first control unit 43 controls the displacement mechanism to work according to the first control instruction; the displacement mechanism of the traffic cone No. 1 drives the traffic cone No. 1 to move along the third marking 13, the magnetic sensor 45 of the traffic cone No. 1 continuously senses the magnetic field with the magnetic field strength of B3 generated by the third marking 13 and feeds back the magnetic field to the first control unit 43, until the traffic cone No. 1 moves along the third marking 13 to the first marking 11, the magnetic sensor 45 of the traffic cone No. 1 senses the magnetic field with the magnetic field strength of B1, at the moment, the traffic cone No. 1 is positioned on the origin of a rectangular coordinate system, and the first control unit 43 of the traffic cone No. 2 and the traffic cone No. 3 … … respectively controls the displacement mechanism to work and move towards the center of a road until the traffic cone No. 2 and the traffic cone No. 3 … … move to the first marking 11, and the magnetic sensors 45 of the traffic cone No. 2 and the traffic cone No. 3 and the traffic cone No. … … sense the magnetic field with the magnetic field strength of B1, at the moment, the traffic cone No. 1, the traffic cone No. 2 and the traffic cone No. 3 and the traffic cone No. … … are positioned on the first marking 11;
at this time, if the initial position of the split area does not coincide with the origin of the rectangular coordinate system, the transverse coordinate value X of the initial position of the split area is calculated Starting up The moving distance of the traffic cone No. 1, the traffic cone No. 2, the traffic cone No. 3 and the traffic cone No. … … and the traffic cone along the first marking 11 is X Starting up Is a distance of (2); if the initial position of the diversion area coincides with the origin of the rectangular coordinate system, the traffic cones 4 do not move by the distance X Starting up Is X Starting up Is 0;
then, the first control units 43 of the traffic cones 1, 2 and 3, … … and … … respectively control the displacement mechanisms to move along the first marking 11, so that the traffic cones 1, 2 and … … respectively move to the corresponding transverse coordinate value positions, and the transverse distance between the adjacent traffic cones 4 is D, that is, the traffic cones 4 are scattered with the traffic cone 1 as a fixed point, as shown in fig. 6; at this time, the first control unit 43 of the traffic cone No. 1 controls the RFID reader 422 to emit a first radio frequency signal to the RFID tag 421 of the traffic cone No. 2, the RFID tag 421 of the remaining traffic cones 4 and the RFID reader 422 do not work, the RFID tag 421 of the traffic cone No. 2 reversely emits a second radio frequency signal to the RFID reader 422 of the traffic cone No. 1 according to the first radio frequency signal after sensing the first radio frequency signal, the first control unit 43 of the traffic cone No. 1 judges the actual distance D1 between the traffic cone No. 1 and the traffic cone No. 2 according to the received second radio frequency signal, at this time, if D1 exceeds the error range, the first control unit 43 of the traffic cone No. 2 controls the displacement mechanism to move along the first marking 11 until the actual distance D between the traffic cone No. 1 and the traffic cone No. 2 is within the error range;
then the near field communication unit between the traffic cone No. 2 and the traffic cone No. 3 is matched to judge the actual distance D2 between the traffic cone No. 2 and the traffic cone No. 3, and then the adjustment is carried out according to the error range adjustment mode, so that the adjustment is sequentially iterated to the traffic cone No. 7, and the effect of verifying the transverse coordinate value of each traffic cone 4 is achieved;
in the process that each traffic cone 4 moves along the first marking 11, the magnetic sensor 45 of each traffic cone 4 detects the magnitude of the magnetic field intensity B1 generated by the first marking 11 in real time, when the traffic cone 4 deflects in the moving process, the detected magnetic field intensity B1 is reduced, at the moment, the first control unit 43 controls the displacement mechanism to correct the travelling direction, so that the detected magnetic field intensity B1 is kept within an error range, the traffic cone 4 is always positioned above the first marking 11, and the error generated by the deflection when the traffic cone 4 moves transversely is reduced;
after the lateral adjustment of each traffic cone 4 is completed, as shown in fig. 6, the traffic cone No. 1 is held at the coordinate value (X Starting up 0), the traffic cone No. 2 and the traffic cone No. 3 and the traffic cone No. … … move toward the road center (i.e., along the longitudinal direction) until the respective magnetic sensors 45 detect the magnetic field with the magnetic field strength of B2, the traffic cone No. 2 and the traffic cone No. 3 and the traffic cone No. … … read the magnetic field strength of B2n of the current position respectively, and at this time, the current magnetic field strength of B2n is compared with the magnetic field strength of B2m of the respective corresponding first target position, the coordinate value of which is (X Starting up When n is an integer greater than 1, and when B2n is greater than B2m, the current position is deviated from the first target position in a direction away from the origin, and the first control unit 43 controls the displacement mechanism to move along the second reticle 12 in the direction of the origin until the magnetic field strength detected by the magnetic sensor 45 is B2m, the first target position is obtained; if B2n is smaller than B2m, the current position deviates from the first target position in a direction approaching the origin, at this time, the first control unit 43 controls the displacement mechanism to move along the second marking 12 in a direction away from the origin until the magnetic field strength detected by the magnetic sensor 45 is B2m, which is the first target position, and if b2n=b2m, the current position coincides with the first target position; since the magnetic field strength B2 of the second reticle 12 is linearly changed, the gain factor of B2 is a, and the correction factor is: k=a (B2 m-B2 n)/d, and then each traffic cone 4 calculates the intersection based on the longitudinal coordinate value Ym of the placement positionIf the value of d1 is smaller than 0, it means that the placement position of the traffic cone 4 is located on the side of the second marker line 12 close to the first marker line 11, and the traffic cone 4 moves K (Ym-d) along the second marker line 12 from the first target position as a start point and in the opposite direction of the deviation to reach the second target position, and the coordinate value of the second target position is (X Starting up When D1 is greater than 0, the traffic cone 4 is positioned on the side of the second marker 12 away from the first marker 11, and the traffic cone 4 moves K (Ym-D) along the second marker 12 from the first target position in the opposite direction of the deviation to reach the second target position, and the coordinate value of the second target position is (X) Starting up A + (n-1) D-K (Ym-D, D), if D1 is equal to 0, the current position of the traffic cone 4 is the placement position; then the traffic cone No. 2 and the traffic cone No. … … and the traffic cone No. 7 move from the second target position to the placement position; thus, the offset of the traffic cone 4 to the placement position is calculated in advance to compensate the offset of the traffic cone 4 generated in the subsequent movement so as to reach the predetermined placement position.
