Vehicle automatic guiding control system

Abstract

The invention provides a vehicle automatic guiding control system which comprises a battery, a control module, a motor controller, a first motor, a second motor, a signal processor and a mechanical device. The control module sends a control signal to the motor controller, and the motor controller controls the first motor and the second motor to work respectively, so as to drive the mechanical device to move. After being synthesized through a signal processor, the driving signals of the first motor and the second motor control the movement of the mechanical device. The control module is a dual-core controller which comprises an ADSP (Advanced Signal Processing) circuit and an FPGA (Field Programmable Gate Array) circuit, wherein the ADSP circuit achieves the functions of human-computer interface, route planning, data storing, input and output control and online output; with the FPGA circuit, a multi-axis servo system transmits a multi-axis control signal to the motor controller; and the ADSP circuit and the FPGA circuit are connected for communicating, and exchanging and transferring data in real time.

Description

technical field [0001] The present invention relates to the technical field of automated guided vehicles (AGV, Automated Guided Vehicle), and in particular to an automated guided vehicle control system. Background technique [0002] Automated Guided Vehicle (AGV for short), refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, with safety protection and various transfer functions, in industrial applications It does not require a driver and uses a rechargeable battery as its power source. Generally, the computer can be used to control its travel route and behavior, or the electromagnetic track can be used to set up its travel route. The electromagnetic track is pasted on the floor, and the unmanned van moves and moves according to the information brought by the electromagnetic track. [0003] Compared with walking, crawling or other non-wheeled mobile robots, AGV has the ...

AI Technical Summary

Problems solved by technology

[0007] (1) Since the above motion control system is based on the motion control of "microprocessor + motion control chip", this type of motion controller is easy to develop and has high reliability, but due to the use of a dedicated motion control chip, it cannot be extended. , and it is impossible to implement various advanced motion control algorithms

[0008] (2) It is difficult to develop programs based on DSP, and requires developers to have high knowledge of C language or assembly language, and secondary development is difficult

[0009] (3) A single-chip DSP is difficult to meet the requirements of a multi-signal processing system. If a new processor is added to meet the requirements of AGV's rapidity and stability, it also needs to deal with issues such as synchronization and communication between the two processors. system development time

[0010] (4) Due to the interference of unstable factors in the surrounding environment, the single DSP controller often appears abnormal, causing loss of control and poor anti-interference ability
