[0029] Figure 2 A schematic diagram of a partial beam yard electronic map provided in an embodiment of the present application. DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides an auxiliary driving system for a tire-type transporter, which realizes semi-automatic transportation of the tire-type transporter 12. The operator is no longer required to participate in the operation throughout the entire process (hooking, lifting, transporting, lowering, and unhooking) but only needs to hook and unhook, thereby reducing the workload of the operator, greatly releasing the operator's energy, and improving the transfer efficiency and safety performance.

[0032] like Figure 1 As shown, in a first aspect, the present application discloses an assisted driving system for a tire-type transporter, and the assisted driving system includes a map positioning unit and a driving deviation correction unit.

[0033] Map positioning unit is used to store the electronic map of the beam yard Figure 1 , beam field electronic ground Figure 1 It is converted in advance based on the design layout of the beam yard and the data from on-site survey.

[0034] Map positioning unit in beam yard electronic map Figure 1In the method, a plurality of theoretical planning routes from the demoulding pedestal to the beam storage pedestal 11 are preset, that is, the theoretical planning routes from the starting point to the destination. Specifically, the demoulding pedestal refers to the position where the beam pieces are cast and formed, and the beam storage pedestal 11 refers to the position where the beam pieces are stored.

[0035] The map positioning unit also marks the operation switching point 13 in each planned route to facilitate subsequent driving to the operation switching point 13 to switch between straight driving and lateral driving.

[0036] Specifically, the beam field electronically Figure 1 , the theoretical planned route and the operation switching point 13 are all pre-stored in the map positioning unit.

[0037] The map positioning unit is also used to obtain the electronic location of the tire transporter 12 in the beam yard. Figure 1 The real-time position in the front-to-back direction.

[0038] The driving deviation correction unit selects the nearest theoretically planned route according to the demoulding pedestal and the beam storage pedestal 11, that is, selects the optimal driving route according to the departure and destination. After selecting the optimal driving route, the wheeled transporter 12 is controlled to drive along the theoretically planned route. Figure 1 The real-time position in the left and right directions of the vehicle is corrected in real time based on the offset between the real-time position in the left and right directions of the vehicle and the center line of the selected theoretical planned route. Specifically, the wheeled transporter 12 is always guided to travel along the middle of the theoretical planned route to ensure driving safety.

[0039] The assisted driving system of the present application includes a map positioning unit and a driving deviation correction unit. Figure 1 The theoretical planning route is pre-stored in the map positioning unit, and then during the actual driving, the map positioning unit obtains the electronic map of the tire transporter 12 in the beam yard. Figure 1 The real-time front and rear positions of the tire transporter 12 are obtained by the driving correction unit. Figure 1 The left and right real-time positions are known. When deviation occurs in the left and right directions, real-time deviation correction is performed to always guide the tire-type transporter 12 to travel along the middle of the theoretically planned route. The assisted driving system of the present application can automatically move between the demoulding base (departure point) and the beam storage base 11 (destination), and perform automatic left and right deviation correction to achieve semi-automatic safe and reliable transportation of beam pieces, thereby reducing the workload of operating workers and improving the efficiency of beam piece transportation.

[0040] like Figure 2 As shown, in one embodiment, the map positioning unit is also used to mark the operation switching point 13 in each theoretically planned route, and the driving correction unit is also used to control the tire-type transporter 12 to switch between straight and horizontal operation at the operation switching point 13. Figure 1It includes several roads that intersect vertically and horizontally, and the operation switching point 13 is located at the intersection. Figure 1 It is not an open map, but a pre-set criss-cross map.

[0041] The tire transporter 12 is provided with a plurality of telescopic legs, and the driving correction unit is also used for controlling the telescopic legs of the tire transporter 12 to extend to the lowest position against the ground at the operation switching point 13, so as to facilitate the tires to slightly leave the ground and rotate; all tires of the tire transporter 12 rotate to switch between the front and rear straight-moving state and the left and right horizontal state.

[0042] Specifically, when the map positioning unit detects that the wheeled transporter 12 is on the beam field electronic map, the map positioning unit detects that the wheeled transporter 12 is on the beam field electronic map. Figure 1 When the real-time position in the front-to-back direction reaches the operation switching point 13, the driving correction unit controls the telescopic legs to extend to the lowest position against the ground, so that the tires can slightly leave the ground and rotate. After the steering is completed, the signal is fed back to the driving correction unit. After receiving the command, the driving correction unit controls the telescopic legs to retract, and the tire transporter 12 continues to move until it reaches the end point and stops.

[0043] The assisted driving system of this application is based on a special vertical and horizontal staggered beam field electronic map. Figure 1 At the operation switching point 13, i.e. the intersection, the front and rear straight-line mode and the left and right horizontal mode are switched. On the basis of automatic driving of front and rear positioning and left and right positioning, automatic steering control is performed to achieve flexible driving in the entire map and improve the transportation efficiency of the beam pieces.

[0044] In one embodiment, the map positioning unit includes a GPS (Global Positioning System) fixed base station pre-deployed in the beam yard area, and a vehicle-mounted GPS antenna and a data processing board card arranged in the center of the tire transporter 12.

[0045] Specifically, the vehicle-mounted GPS antenna is arranged in the center of the tire transporter 12, and the vehicle-mounted GPS antenna is arranged in the upper and lower positions of the center of the horizontal frame of the tire transporter 12 through an auxiliary connection structure. The data processing board arranged in the tire transporter 12 is used to obtain real-time location data, store and process the real-time location data.

[0046] The GPS fixed base station, satellite and vehicle-mounted GPS antenna locate the front and rear real-time positions of the tire transporter 12 through differential positioning technology.

[0047] Specifically, the differential positioning system uses carrier phase difference to perform positioning, which has high positioning accuracy.

[0048] The assisted driving system of the present application performs real-time forward and backward positioning with high positioning accuracy through a GPS fixed base station, a vehicle-mounted GPS antenna and a data processing board.

[0049] Preferably, the positioning accuracy can reach 50 mm.

[0050] In one embodiment, the tire transporter 12 includes a first drive mechanism and a second drive mechanism. The first drive mechanism and the second drive mechanism are two completely independent drive mechanisms. Therefore, during continuous movement, there may be a situation where the left and right directions along the forward direction are offset, resulting in a problem of poor effect.

[0051] In order to solve the above problem, the driving deviation correction unit includes a data processor and two vehicle-mounted GPS antennas respectively arranged at the left and right center points of the first driving mechanism and the second driving mechanism.

[0052] Two vehicle-mounted GPS antennas obtain the left and right real-time positions of the two drive structures in real time. The data processor calculates the left and right real-time deviations between the left and right center points of the two drive structures and the center line of the theoretical planned route, and controls the two drive mechanisms to perform real-time deviation correction.

[0053] Specifically, when the left-right center point of the first drive mechanism is located at the center line of the theoretically planned route, the two wheels of the first drive mechanism are just symmetrical about the center line of the theoretically planned route, indicating that the left-right real-time deviation of the first drive mechanism is zero. Similarly, when the left-right center point of the second drive mechanism is located at the center line of the theoretically planned route, the two wheels of the second drive mechanism are just symmetrical about the center line of the theoretically planned route, indicating that the left-right real-time deviation of the second drive mechanism is zero. If the left-right real-time deviation of any drive mechanism is not zero, real-time adjustments are made to ensure that the tire transporter 12 always travels along the center line and ensures the driving safety performance of the tire transporter 12.

[0054] Specifically, when the left and right real-time deviation of any driving mechanism is not zero, the data processor of the driving correction unit adjusts the speed of the driving mechanism or slightly swings the wheels of the driving mechanism to make the tire transporter 12 travel along the center of the road.

[0055] In one embodiment, the data processing board includes a GNSS (Global Navigation Satellite System) module and a drawing module; the GNSS module is used to convert the design layout of the beam yard into a preliminary electronic map in advance; the drawing module is used to correct the preliminary electronic map according to the on-site survey data of the beam yard to obtain the electronic map of the beam yard. Figure 1 First obtain a preliminary electronic map, and then modify it according to the on-site survey data of the beam yard, so that the electronic map of the beam yard can be obtained more efficiently. Figure 1 .

[0056] In one embodiment, the assisted driving system further includes a laser measurement unit and a hanging unit.

[0057] The laser measurement system is used to identify the type of beam pieces on the beam storage pedestal 11 or the demoulding pedestal. Specifically, by identifying the type of beam piece, the various dimensions of the beam piece are known, among which the height dimension is mainly the dimension.

[0058] The hoisting unit is used to control the tire-type transporter 12 at the beam storage pedestal 11 or the demoulding pedestal according to the type of beam piece, and control the initial lifting height and the final lifting height of the hook, so as to facilitate hanging and transportation.

[0059] Specifically, the hanging or unhooking on the beam storage pedestal 11 or the demoulding pedestal is completed with the assistance of operating staff.

[0060] The assisted driving system of the present application is provided with a laser measurement unit and a hoisting unit, which facilitates efficient hanging and unhooking, greatly saves the hoisting time, and improves the transportation efficiency of the beam pieces.

[0061] In one embodiment, the auxiliary driving system further includes a video detection unit, which is used to obtain real-time video of the tire transporter 12 and feed it back to a remote display screen, thereby enabling an operator to remotely view the real-time working status of the tire transporter 12.

[0062] In one embodiment, the assisted driving system further includes an edge contact alarm unit. When the tire transporter 12 comes into contact with an external obstacle, the edge contact alarm unit controls the tire transporter 12 to stop and issues an alarm, thereby greatly improving the safety performance of the tire transporter 12 during operation.

[0063] In the second aspect, the present application discloses an embodiment of a beam yard central control system, which includes a control center and a plurality of wheeled transporters 12 with the above-mentioned auxiliary driving system. The control center remotely and simultaneously dispatches all the wheeled transporters 12 to the beam yard electronically. Figure 1 The transporting work of multiple tire transporters 12 is carried out simultaneously.

[0064] The beam yard central control system of the present application can remotely dispatch all wheeled transporters 12 to the beam yard electronically. Figure 1 During operation, multiple tire transporters 12 can be used simultaneously to transport beam pieces, which greatly improves the efficiency of beam piece transfer and saves the time and energy of operators.

[0065] In a third aspect, the present application further discloses an assisted driving method based on the above assisted driving system, comprising the following steps:

[0066] Based on the demoulding base where the tire transporter 12 is located, the beam field is electronically Figure 1 The position (i.e., the starting position) is determined, and the beam storage pedestal 11 to be reached (i.e., the end position) is selected. The driving correction unit selects the nearest theoretical planning route based on the demoulding pedestal and the beam storage pedestal 11.

[0067] The driving correction unit controls the wheeled transporter 12 to travel along the theoretically planned route; during the driving process, the wheeled transporter 12 is obtained in the beam yard electronic map. Figure 1 The left and right real-time positions are measured, and real-time correction is performed based on the offset between the left and right real-time positions and the road centerline of the selected theoretical planned route.

[0068] In one embodiment, the beam field is electronically Figure 1 It includes several roads that intersect vertically and horizontally, and the operation switching point 13 is located at the intersection. Figure 1 It is not an open map, but a pre-set criss-cross map.

[0069] The tire transporter 12 is provided with a plurality of telescopic legs, and the driving correction unit is also used for controlling the telescopic legs of the tire transporter 12 to extend to the lowest position against the ground at the operation switching point 13, so as to facilitate the tires to slightly leave the ground and rotate; all tires of the tire transporter 12 rotate to switch between the front and rear straight-moving state and the left and right horizontal state.
