Wireless control system of automated guided vehicle

Abstract

The invention provides a wireless control system of an automated guided vehicle, comprising a battery, a control module, a motor controller, a first motor, a second motor, a third motor, a signal processor and a mechanical device, wherein the first motor and the second motor are used for driving the mechanical device to move, and the third motor is an automatic loading motor. The system further comprises a wireless control module, wherein the wireless control module is in communication connection with the control module so as to wirelessly control the automated guided vehicle to move, the battery is sequentially connected with the control module and the motors, the motor controller is further connected with the signal processor after being connected with the first motor, the second motor and the third motor, and the control module is a binuclear controller and comprises an ADSP (Advanced Digital Signal Processor) circuit and an FPGA (Field-Programmable Gate Array) circuit.

Description

technical field The present invention relates to the technical field of automated guided vehicles (AGV, Automated Guided Vehicle), and in particular to a wireless control system for automated guided vehicles. Background technique 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. Compared with walking, crawling or other non-wheeled mobile robots, AGV has the advantages ...

AI Technical Summary

Problems solved by technology

(1) After the trolley arrives at the station, due to the preset dwell time of the trolley program, due to the influence of other surrounding factors, the loading and unloading of the goods may not be completed. The dwell time of this station has been reached, and the trolley begins to complete the function of going to the next station, resulting in incomplete specified action

(2) If there are people at each station, the stop function is manually operated. On the one hand, the degree of automation is greatly reduced. On the other hand, human factors sometimes interfere with the normal operation of the car. stop by signal

(3) A series of measures such as various pressure sensors and photoelectric sensors will be used on the higher-level AGV car to ensure the loading and unloading function of the car, which will undoubtedly increase the complexity and control difficulty of the whole car

(4) In places where there are cross tracks, two or even more AGV cars may collide, causing the tracks of all cars to be blocked and unable to complete specified actions. Under such conditions, it is necessary to artificially restart the AGV , the degree of automation is greatly reduced

(5) Before the trolley leaves the station, its movement stations are generally set up, or it walks from station to station. If you want to change the new station mode after arriving at a certain station, you have to go to the site to intervene artificially. Meet the requirements of AGV trolleys with high automation requirements

(6) When the AGV car enters the uninhabited area, its walking speed is generally determined by the setting of the previous station and cannot be modified, which is not conducive to acceleration and deceleration under complex working conditions

(7) Since the AGV is walking, the confirmation of the site is determined according to the reflection device on the ground, there must be a problem with the reading of the site, and the function of the site after the car will be completely wrong

Since it is very difficult for a single DSP system to handle multi-motor synchronous linkage, if the above problems are required again, a single DSP resource will not be able to meet the requirements
