[0004] However, there are some specific scenarios. For example, white tiles or other highly reflective materials are pasted on the wall about 2 meters in front of the transport vehicle. Due to the strong reflective material, the obstacle sensing area of the transport vehicle will be forcibly enlarged, and then an obstacle alarm will be sent when there is no obstacle
Another example: when the space at the corner is small, although there are no obstacles on the guiding path of the transport vehicle, the transport vehicle can pass through normally, but because the wall at the corner will enter the obstacle sensing area, it will also cause the obstacle alarm to fail. parking
[0005] In the prior art, the obstacle sensor on the transport vehicle is affected by the environment, resulting in an obstacle alarm when there is no obstacle on the guiding path of the transport vehicle, causing the transport vehicle to stop running. No effective solution has been proposed so far. solution

Embodiment 1
[0031] According to an embodiment of the present invention, an embodiment of a control system of a transport vehicle is provided, figure 2 is a schematic diagram of a control system of a transport vehicle according to an embodiment of the present invention, such as figure 2 As shown, the system includes:
[0032] The barrier-off control card 10 set at the first preset position on the guide path, wherein the barrier-off control card carries a barrier-off command, and the barrier-off command is used to control the transport vehicle to turn off the obstacle detection function:
[0033] The transport vehicle 20 running according to the guiding path; wherein, when the transport vehicle moves to the first preset position, the barrier closing control card controls the transport vehicle to close barriers.
[0034] Specifically, the above-mentioned guiding path may be an electromagnetic track, and the transport vehicle runs along the guiding path. The above-mentioned barrier-off co...
Embodiment 2
[0052] According to an embodiment of the present invention, an embodiment of a control system of a transport vehicle is provided. It should be noted that the steps shown in the flowcharts of the drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.
[0053] Figure 6 is a flowchart of a control method of a transport vehicle according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:
[0054] Step S61, detecting the position of the transportation vehicle on the guiding path.
[0055] Step S63, when the transport vehicle is at a first preset position on the guiding path, issue a barrier closing command to the transport vehicle, wherein the barrier closing command is used to control the transport vehi...
Embodiment 3
[0103] According to an embodiment of the present invention, a storage medium is provided, which is characterized in that the storage medium includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to perform the transportation described in Embodiment 1 car control method.

Abstract
The invention discloses a control system and method of a transport vehicle. The control system includes an obstacle closing control card arranged on the first preset position on a navigation path anda transport vehicle following the navigation path, wherein the obstacle closing control card carries obstacle closing commands which are used for controlling the transport vehicle to turn off the obstacle detection function, and when the transport vehicle runs to the first preset position, the obstacle closing control card controls the transport vehicle to close obstacles. According to the controlsystem and method of the transport vehicle, the technical problems that in the prior art, an obstacle alarm is generated under the condition of no obstacles on the navigation paths of the transport vehicles due to the fact that obstacle sensors on the transport vehicles are affected by the environment, and consequently the transport vehicles stop running are solved.
Description
technical field [0001] The present invention relates to the field of transport vehicle control, in particular to a control system and method for transport vehicles. Background technique [0002] AGV (Automated Guided Vehicle) is a transport vehicle equipped with automatic guidance devices such as electromagnetic or photoelectric, capable of driving along a prescribed guiding path, and has safety protection and various transplanting functions. There is no need for a driver in industrial applications. Usually, the computer controls its travel path and behavior, or uses electromagnetic rails to set up its travel path. The electromagnetic rails are pasted on the floor, and the truck travels according to the electromagnetic rails. [0003] During the operation of the transport vehicle, but the on-site working environment is relatively harsh, forklifts often pass by, causing damage to the function card, so there may be obstacles on its driving path, so the transport vehicle is equ...
