Control method for realizing long-distance position detection by combination of encoder and limit

Abstract

The invention provides a control method for realizing long-distance position detection by combination of an encoder and limit. The control method comprises the steps of: 1, fixing an armature used for triggering the limit combination to transmit signal on the pathway of a moving vehicle, wherein the limit combination is installed on a vehicle body for determining the position of a vehicle interval; forming serial codes when the mechanical limit is orderly triggered, converting the codes to be decimal, wherein number at the tens position is used for distinguishing sets or control system range, and the number at the unit position is used for distinguishing position function or specific location of the interval; 2, amending the encoder data by the limit combination; and 3, implementing vehicle control by adopting a limit combination encoding mode (figure 1) and limit encoding definition comparison (figure 2). The mechanical limit combination encoding is applicable to identifying co-orbit multipoint orientation parking positions, and the combination of mechanical limit and the encoder is applicable to long-distance real-time position measurement and disposition.

Description

Technical field [0001] The invention involves the automatic avoidance control technology of steelmaking cross -building vehicles, realizing the accurate deceleration of the vehicle, accurately setting up parking, and automatic collection of its data to transmit it to the central control system. Background technique [0002] At present, the method adopted in the steelmaking crossing car system is: (1) Limit positioning control can only send positioning signals to the corresponding buses on the corresponding point, and the location of the trolley running or stopping between limited positions cannot be recognized and cannot be recognized.Related information of the vehicle; (2) The laser rangefinder has a car reflective board and the ground fixed laser laser transmitting station for measurement. Due to the fierce shaking of the trolley in the fast -running, laser laser cannot be effectively reflected by the reflective board, and the data is often lost; (3 3 (3 3 (3 (3) The single -co...

Problems solved by technology

[0002] At present, the methods adopted in the steelmaking traverse trolley system are: (1) The limit positioning control can only send a positioning signal to the trolley at the corresponding point, and cannot recognize or recognize the position of the trolley running or stopping between the limit positions Vehicle-related information; (2) The laser rangefinder has a vehicle-mounted reflector and a ground-mounted laser transmitting station for measurement. Due to the severe shaking of the fast-moving trolley, the laser cannot be effectively reflected by the reflector, and the data is often lost; (3 ) A single encoder cannot achieve long-distance measurement. In order to prevent vehicle collisions, vehicles with the same purpose avoid and wait at the limit position. The waiting distance is long, causing the continuous casting machine to be forced to reduce the production speed
