Wireless induction cable unit and rotating code device combined location detection system

Abstract

Disclosed is a position detection system which combines a wireless induction cable device and a rotary encoder, comprising a wireless induction cable position detection device, a CPU and a rotary encoder, the CPU receives the information of a first address output by the induction cable position detection device and calculates the vehicle speed according to the first address information. When the vehicle speed is high or medium, the CPU calculates the running position of the vehicle according to the first address information, and when the vehicle speed is low, the CPU reads the value of the rotary encoder of a driven wheel and calculates the information of a second address according to the value, and the CPU calculates the running position of the vehicle according to the first address information and the second address information. The position detection system is applicable to the dynamic position detection for running objects having high detection accuracy demand in bad circumstances, in particular to running position detection for four types of vehicles in the coking industry.

Description

technical field [0001] The invention relates to a detection system for the running positions of four types of vehicles (coke pushing vehicles, coke guiding vehicles, coal vehicles and electric vehicles) in the coking industry. Background technique [0002] Due to the operating characteristics of the four major types of vehicles in the coking industry (coke pushing vehicles, coke guiding vehicles, coal vehicles, and trams), it is necessary to detect their operating positions. In the prior art, a wireless induction cable position detection device and a rotary encoder position detection device are usually used for position detection. [0003] The wireless induction cable position detection device is an absolute position detection device, which is mainly composed of an address code generator, a power amplifier, an impedance matcher, an induction code cable, two induction antennas, an address code receiver, and a central processing unit. The address coding and analysis are reali...

AI Technical Summary

Problems solved by technology

Although the resolution is high, the counting of the rotary encoder may be inaccurate due to the slippage of the driven wheel

In general use, the overshoot problem during travel cannot be overcome, so it is also unable to meet the special control occasions that have higher requirements for detection resolution.
