Embodiment 1

[0039] Aiming at the AGV control system in the prior art and the corresponding control method, this solution provides a control system for handling automatic guided transport vehicles, including tracks, automatic guided transport vehicles and control systems. The track is provided with Positioning card, a number of branch tracks are set in the track to form different trajectory modes, the control system automatically guides the transport vehicle through wireless connection, and obtains the position of the automatic guided transport vehicle through the positioning card. This solution can provide several kinds of orbits for AGV to work, set different orbits for different requirements, and set different trajectory modes. The console includes screens that display real-time AGV and track status, as well as manual buttons. It is convenient to monitor and control the AGV.

[0040] The control system includes a PLC system, wherein real-time wireless data exchange is performed through...

Embodiment 2

[0046] The control method of the automatic guided transport vehicle control system, the steps are as follows:

[0047] A. Several automatic guided transport vehicles are connected to the control system through the wireless system, and different equipment numbers are set for different automatic guided transport vehicles and control systems;

[0048] B. The automatic guided transport vehicle moves through the track and its own control program, and the control system monitors and controls different automatic guided transport vehicles through different equipment numbers;

[0049] C, and locate the position through the positioning card, and select the corresponding track to run;

[0050] D. When multiple automatic guided transport vehicles are running, other cars are prohibited from entering the track of the existing automatic guided transport vehicles or the required cars are allowed to enter according to the needs. According to the needs, some tracks are set so that multiple cars...

Embodiment 3

[0053] For the realization of the track selection of a single AGV, the method of card positioning is adopted now, and two positioning cards need to be placed, among which the positioning card 2 is located at the intersection of the tracks that need to be changed, and the positioning card 1 is located 10cm in front of the positioning card 2. After passing through positioning card 1 and positioning card 2 in turn, the input flag position 1 of the role of positioning card 1, three conditions are connected in series in the PLC ladder diagram, which are respectively the flag position of positioning card 1, the track change flag position of the host computer, and Positioning card 2 corresponds to 8 io bits. If the three conditions are met, the subroutine can be entered for lane change operation, the car will change lanes by itself and exit the subroutine, and the upper computer will issue a command to change the lane flag position 1, and then enter the lane change execution.

Abstract

The invention discloses a control system and a control method for carrying an automated guided vehicle (AGV), which belongs to the field of electromechanical integration and is based on mutual communication between single AGVs with PLC as a main control module and the overall scheduling. The control system connects a variable to the PLC and changes the corresponding variable through wireless communication so as to realize the function of AGV real-time control. At the same time, the AGVs feed back the data in real time, including the specific positions of the AGVs and signal communication in a control area. The control system realizes traffic control of multiple AGVs, and memory variables of a host computer are used for real-time assignment to each control area marker, so as to control each AGV in real time. For each AGV, there are both automatic and manual operating modes, where there are real-time orbital transformation and speed selection functions in the automatic state. The control system and the control method of the invention can be widely used in intelligent warehouse transportation and factory transportation occasions with high efficiency, great convenience and high speed.

Description

technical field [0001] The invention relates to the field of mechatronics, and more specifically, relates to a control system and control method for handling automatic guided transport vehicles. Background technique [0002] The manufacturing industry in the 21st century will enter a new stage, and agile manufacturing will become the dominant mode of enterprises. Whether it can seize market opportunities and develop new products will be the main means for enterprises to win the competition. To reduce the dependence of production cost on production batches, it is necessary to develop agile manufacturing equipment. The programmable, reconfigurable, and fast response capabilities of heavy manufacturing equipment enable low-volume production to achieve efficiencies close to medium- and high-volume production. Since the robot has the characteristics of autonomous planning, programmable, coordinated operations, and sensor-based control, it will become an important part of reorga...
