DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The automatic road transport device of the present invention, like other general road automatic transport devices, must include an automatic navigation system, except that the automatic navigation system of the present invention is disposed on a frame for carrying goods, the frame A power drive system for driving the frame movement is provided. Specifically, the frame is a frame that can adapt to the track of different models or different sizes of containers, and loads and fixes the vehicle or the cargo thereon, as shown in FIG. 1 , on the fixed position 5 on the frame 1 A vehicle 2 is placed, and at the rear of the frame is placed an engine 3 for driving the bottom wheel 6 and driven by petroleum, electric power, or various new energy sources, and a positioning device reader 4 is disposed at the bottom of the frame. 2 is a bottom view shown in FIG. 1. The split type frame shown in FIG. 3 carries a container, which is a split structure composed of two panels, and the length can be adjusted in the middle to adapt to different containers. The length is required to be connected between the panels by the communication cable 7. Figure 4 is a bottom plan view of the apparatus of Figure 3. A surrounding environment sensing device, a communication device, a positioning device, and a control device are installed on the frame. The positioning device reads the position information of the road surface, and also receives the satellite positioning information, and transmits the information to the control center, and the control device receives the control signal of the control center. And the environmental signal of the environmental sensing device controls the power drive system of the frame to realize automatic transportation and transport the vehicle or cargo to the designated destination. Specifically, the frame has a built-in panel, a locker, a wheel, a bumper bar, a battery or energy box storage area, a basic structure such as an engine (and a cable connector if AC power is used), and a positioning device is installed to sense the surrounding environment. Device, communication device, control device. The mounted panel may be an integrated structure, or may be a split structure to reduce weight and more conveniently adapt to different sizes of vehicles and cargo, and the split panels are connected by cables to transmit sensing information and control commands; the locker can lock the vehicle or Cargo; the anti-collision bar installed as a buffer device on the left and right sides can be made of spring or rubber elastic pad. The anti-collision bar can be protected from the aesthetic appearance of the vehicle, so that the energy absorption distance can be longer and safer. The battery or energy storage area is not limited by the size of the vehicle. Can do more, so that it has more reserve energy; the engine can also make more breakthroughs by breaking the volume limit of the vehicle; if the frame uses the cable laid along the road to obtain AC power as the driving energy, it needs a cable connector and Cables are connected. The positioning device is composed of an object mounted on the road containing position information and a reading device mounted on the frame; the surrounding environment sensing device can be various forms of radar, capable of sensing obstacles around the frame and other frames. Distance; The communication device is a wireless device for communication with other frames and communication with the total road control device; the control device is responsible for processing the data transmitted by various devices, and selecting the best trajectory and speed for the frame. And all driving-related actions related to the frame, such as emergency braking. The frame used for automatic transportation on the highway can be provided by the expressway operator. Because the frame is large, there is enough space to store batteries or new energy storage equipment, and a large engine can be installed to achieve more powerful power, faster travel speed and longer driving distance. At the same time, for the battery frame, the standard size battery can be used. In the energy supply center (similar to the current gas station), the energy can be supplemented by quickly changing the battery pack. In addition, there is also a possibility: By erecting cables along the road, the electric power is directly driven from the cable to drive the motor to drive, so that the power will be more powerful, the cost is lower, and the energy supply to the energy supply center is saved. Time loss. The positioning device used for automatic transportation on the expressway, because the road environment may have various obstacles, such as rain, snow, debris, etc., the object containing the position information may use the radio frequency identification chip. Radio frequency identification chip is installed on the road, and the frame can be driven by the chip reading device at the front end and the back end. The attitude, the position on the highway, the position of the line in the opposite lane, the driving speed, the maximum speed limit of the road section, etc. are accurately sensed, so that the driving trajectory is adjusted by the control device on the frame. For the frame used in the parking lot, it can be provided by the parking lot management. In terms of the object including the position information of the positioning device, since the parking environment is relatively simple - and there are fewer obstacles, in addition to the RFID chip, other objects including position information, such as a barcode or a QR code, may be used. To contain similar information contained in the above RFID chip, the above-mentioned functions can be realized by equipped with a bar code or a two-dimensional code reading device at the front end and the back end. The use of manned vehicles directly on the automated transport frame will likely fundamentally change the current state of the long-distance drive to the destination. The manned car will be fully transported on the frame for automatic transportation on the expressway. After leaving the expressway, the car can also be easily separated from the frame and continue to travel in the traditional manned mode. The use of the car on the automatic transport frame can also be used for automatic parking in the parking lot. When the car is parked at the entrance of the compound or at the entrance of the parking lot, the frame will automatically carry the car to the open parking lot or the corresponding parking space of the multi-storey car park for parking. When the car needs to be picked up, the frame can automatically The car is carried to the entrance of the compound or at the entrance of the parking lot. This equipment can also be used for the automatic transportation of goods. The container box or the cargo itself carrying the cargo is fixed on the automatic transport frame, and the automatic transportation can be carried out. At the destination or transfer station, depending on the actual situation, whether it is transferred to the traditional truck. This type of transportation will greatly reduce the consumption of human resources and greatly improve the automation of road transportation. Degree. For the case of installing an object having position information on the road surface, the preferred solution is to use a radio frequency identification chip, and each lane is arranged in the middle of the lane in the direction of the traffic flow, and each chip on a straight line perpendicular to the direction of the traffic flow is grouped into a group. The group chip comprises two or more chips, and the preferred solution is four or more chips per group. The information contained in the chip includes: chipset serial number, chip serial number, lane, maximum speed limit, and so on. Two left and right reading devices are mounted on the head and the tail of the frame. Under normal circumstances, as shown in Figure 5, during the normal driving of the frame to the left, the left reading device of the frame head will read the a3 chip, and the right reading device will read the a2 chip, the tail portion. The left reading device will read the e3 chip, and the right reading device will read the e2 chip; when the frame driving posture is shifted, cross reading will occur, as shown in Fig. 6, the frame When an offset occurs during the leftward driving, the left reading device of the head reads the a4 chip, the right reading device reads the a3 chip, and the left reading device reads the e2 chip. The right reading device reads the el chip. When the read data is fed back to the control device, the control device will recognize the degree of deviation of the driving posture, thereby controlling the frame to perform direction compensation and returning the frame to the normal driving posture. Similarly, the object containing the positional information may also be a barcode, a two-dimensional code, etc., and the same can be achieved by replacing the chip with the object and replacing the reading device mounted on the frame with the corresponding reading device. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes made by the contents of the present invention and the description of the invention are Modifications, still in the claims of the present invention Within the scope of coverage. In addition, the abstract sections and headings are only used to assist in the search of patent documents and are not intended to limit the scope of the invention.
