Laser distance measurement is used as positioning technology in self-propelled trolley suspension co

Intelligent bicycle trolley is designed with PLC or intelligent module, through the pre-designed control programme, it can automatically adjust the running speed and running route in real time during the execution of operation tasks.

As an important logistics conveying system, the self-propelled trolley suspension conveying system is widely used in automobile manufacturing, construction machinery and other industries because of its space-saving, flexible, safe and reliable work and intelligent control system. In the production mode of assembly line operation, the performance of the self-propelled trolley suspension conveying control system is directly related to the production efficiency of the enterprise. 

Self-propelled trolley suspension conveying system usually includes a circular track, the upper piece of workstation of the translating turnout workpiece, the lower maintenance self-propelled trolley, which is generally composed of the frame drive device, vehicle controller and other devices, vehicle controller and other devices, vehicle controller and other devices, vehicle controller and other devices, vehicle controller and other devices, vehicle controller and other components. 

According to the functional requirements of the self-propelled trolley suspension conveyor system, the design of its track According to the functional requirements of the self-propelled trolley suspension conveyor system, the design of its track line, turnout diversion, together, the number of the upper workstation, the lower workstation, the number of maintenance placements, as well as each point of the action requirements, the time and the number of self-propelled trolleys. 

According to the travelling speed, the bicycle can be divided into single-speed bicycle and variable-speed bicycle. 

The speed of single-speed bicycle is usually 15m/min, and the speed of variable-speed bicycle is usually 15-30m/min. The design of bicycle speed is determined according to the production beat, conveying distance, the number of workstations and other factors, and the variable-speed bicycle is usually designed with a speed controller to achieve frequency conversion speed regulation. According to the control mode of the bicycle, it can be divided into two types: intelligent type and common type. Intelligent bicycle trolley is designed with PLC or intelligent module, through the pre-designed control programme, it can automatically adjust the running speed and running route in real time during the execution of operation tasks. 

Ordinary type self-propelled trolley is only designed with executive electrics, not with separate PLC or intelligent module, the travelling and lifting device action of the trolley is controlled by the central controller and the centralised two places of the workstation operation box. Tail accumulation and release device is designed to improve the efficiency of transport, bicycle car can be accumulated in any point of the line to transport goods, bicycle car in a station to stop does not hinder the flow of other bicycles and the flow of the order of the bicycle car, when a bicycle car stops, the subsequent bicycle car will be accumulated in the back of it. The tail accumulation device acts as a stopper. 

Laser distance measurement as a positioning technique in the suspension and conveyor system of a self-propelled vehicle 

Laser distance measurement is used for positioning. The laser distance measurement device transmits a very fine laser beam to a reflector plate, and the distance measurement device calculates the distance based on the time difference of the signals reflected back from the reflector plate. Communication modes are bus mode, RS422 mode and so on. 

Laser distance measurement and positioning technology used in the bicycle trolley suspension conveyor system, need to be installed in a specific location (such as the upper workstation, the lower workstation, switch switch) reflective plate, each bicycle trolley installed laser range finder, laser range finder and the trolley PLC controller is connected to the measured distance signal into the controller and the pre-determined distance compared to the controller if the difference value reaches the permissible range, the controller outputs If the difference is within the permissible range, the controller outputs a switch signal to control the motor action of the self-propelled trolley, so that the self-propelled trolley stops or starts at a predetermined position. 

According to the "Global and China Self-propelled Trolley Suspension Conveyor System Industry In-depth Research Report 2021" issued by Xinsiye Industry Research Centre, the major competitors in the China Self-propelled Trolley Suspension Conveyor System market in 2021 are Mitutoyo Intelligence, Siemens, Durr, and Daifuku Corporation of Japan, among others.
