Description

Technical Field

[0001] The present invention relates to the field of autonomous driving technology, and in particular to an AVP coil laying system and method for a PRT vehicle. Background Art

[0002] With the rapid development and increasing maturity of intelligent technology, autonomous driving, new energy and other technologies, rail transit is facing unprecedented challenges and development opportunities. In addition to the maglev, monorail, skyrail, tram and other technologies that have attracted much attention, PRT is also actively developing as a new mode of transportation. It is currently mainly used between the remote parking lot and the terminal building of the airport. PRT can effectively realize the mode of car waiting for people, so that passengers with long-term parking needs can park their vehicles in the remote parking lot to reduce parking fees, and then go to the platform to take the PRT unmanned car from the remote parking lot to the terminal building for boarding.

[0003] The PRT unmanned vehicle belongs to the category of unmanned vehicles. In order to ensure the safety of the vehicle, the AVP (Automatic Vehicle Protection) system was put into operation. The system can fully and effectively ensure the safety of multiple PRT vehicles on the line at the same time.

[0004] Since the PRT vehicle travels on a dedicated road, the AVP coil is laid in the drainage ditch in the middle of the dedicated road. The laying of the AVP coil has certain requirements relative to the height of the vehicle running surface. During the laying process, the height is determined by manual measurement. The installation process is cumbersome and the installation accuracy is slightly low. The laying accuracy of the AVP coil will affect the running speed of the vehicle, causing tremendous pressure in debugging and subsequent operations. Summary of the invention

[0033] Embodiment 1:

[0034] Reference Figure 1-Figure 4 As shown, an embodiment of the present invention provides an AVP coil laying system for a PRT trolley, which is applied to the running road of the PRT trolley to lay and install the AVP coil conductor. The system includes: a plurality of AVP coil installation rails and AVP installation cross supports, wherein:

[0035] The AVP coil installation track is set on both sides of the drainage ditch in the PRT trolley running road. The top of the AVP coil installation track is provided with an installation wire trough, which is used to accommodate the laying of the AVP coil; the AVP installation cross support is clamped with the installation wire trough for the horizontal laying of the AVP coil.

[0036] Furthermore, the system also includes: a cover plate, which is located above the drainage ditch and is laid on the AVP coil installation track through the AVP installation cross support, and is flush with the vehicle walking surface of the PRT trolley.

[0037] Combine the following Figure 1-Figure 4 As shown, the above components are introduced in detail:

[0038] As a preferred implementation of this embodiment, see Figure 1As shown, there are curbstones on both sides of the PRT car-only road, and a drainage ditch in the middle of the road. The AVP coil laying system of the present invention is arranged in the drainage ditch, and a fiberglass cover plate is covered on top of the drainage ditch. The thickness of the cover plate is preferably fixed at 10 mm. The AVP coil is laid in the installation wire trough at the top of the AVP coil installation track. The depth of the installation wire trough is less than 15 mm. The wire trough ensures that the maximum installation height of the AVP coil is 15 mm from the running surface (that is, the height of the AVP coil is fixed at a distance of less than 15 mm from the vehicle running surface). The depth of the drainage ditch along the entire line is certain. A special AVP coil installation track with a fixed height is used here, and a special AVP installation cross support is installed between the left and right wiring installation tracks to fix the AVP coil installation track. In this way, the two special wiring tracks are exempted from the process of drilling and installation, which increases work efficiency and can better locate the height of the AVP coil.

[0039] As a preferred implementation of this embodiment, see Figure 2 As shown, the specially made AVP coil mounting rail is preferably 3 meters long and made of PVC. The specially made AVP mounting cross supports are made of polyamide fiber (nylon). Five AVP mounting cross supports are arranged on each AVP coil mounting rail to increase support and facilitate the crossing of the AVP coil nodes. The position of the AVP mounting cross supports can be shifted or increased or decreased according to the nodes of the coil. In the embodiment of the present invention, the AVP mounting supports can not only effectively support the AVP coil mounting rails, but also meet the requirements for the crossing of the AVP coil nodes.

[0040] As a preferred implementation of this embodiment, see Figure 3 The figure shows a cross-sectional view of the specially designed installation track for the AVP coil. The coil is installed in the track groove, which can effectively ensure the height of the coil from the ground and also speed up work efficiency at the construction level.

[0041] As a preferred implementation of this embodiment, see Figure 4 The following are the layout requirements for the AVP coil: the maximum depth of the AVP coil is 15 mm, the maximum distance between the straight section curbstone and the AVP coil is 665 mm, the minimum width of the straight section AVP coil is 400 mm, and the length range of the AVP coil is 0-25 m. The AVP coil is a closed loop, and each AVP coil is iteratively arranged. A preamplifier is connected at the closed position of each coil ( Figure 4 The small and medium squares represent preamplifiers. The 1m here means that the AVP coil is a rectangular closed coil; when the wires are arranged in a rectangle, the maximum distance from the closed position of the wires to the preamplifier is 1m), and the amplifier is connected to the electrical control box through a feeder.

[0042] As a preferred implementation of this embodiment, see Figure 5 As shown, it is a structural schematic diagram of one end of the AVP installation cross support. The AVP installation cross support has a wire threading groove for the horizontal laying of the AVP coil, which can make the AVP coil be laid along the AVP coil installation track and the AVP installation cross support to form multiple closed rectangles.

[0043] Through the description of the above implementation, those skilled in the art can know that an embodiment of the present invention provides an AVP coil laying system for a PRT trolley, which is applied to the operating road of the PRT trolley to lay and install AVP coil conductors. The system includes: multiple AVP coil installation rails and AVP installation cross supports, and also includes a cover plate; the system is suitable for the special road surface of the PRT trolley, and provides an installation routing rail in view of the particularity of the AVP coil. Installing the AVP coil through this laying system can not only speed up the installation progress and improve work efficiency; it also helps to improve the laying accuracy of the AVP coil, and makes the maintenance of the AVP system more convenient, so that the AVP system has higher reliability; at the same time, the system also has the advantages of simple and reasonable structure and low cost.

[0044] Embodiment 2:

[0045] Reference Figure 6 As shown, an embodiment of the present invention also provides a method for laying an AVP coil of a PRT vehicle, the method comprising:
