A position judging device, system and method for a silo group unloading trolley

Abstract

The invention discloses a position judgment device of a discharging car on cluster bins, comprising position switches, an inductive head and a signal processing unit; wherein, the position switches are arranged on the running track of the discharging car and are corresponding to the edge positions at both sides of each bin; the inductive head is installed on the discharging car and is used for triggering the position switches in sequence when the discharging car moves along the running track; the position switch is used for sending switch actuating signals to the signal processing unit when being triggered; the signal processing unit is used for judging the position and move status of the discharging car according to the received switch actuating signals. The invention also provides a position judgment system and a position judgment method of the discharging car on cluster bins. By adopting the embodiment of the invention, the position information and move status of the discharging car on the cluster bins can be obtained accurately and comprehensively.

Description

technical field [0001] The invention relates to the field of control, in particular to a position judging device, system and method for a bin group unloading trolley. Background technique [0002] The existing silo is loaded through the upper charging point. Since the charging point is fixed, the material will form a conical stockpile in the silo, and the volume of the silo cannot be fully utilized. [0003] Especially for large-scale silos, fixed loading points cannot meet the utilization rate of large-scale silos, so existing large-scale silos generally use mobile unloading trolleys for loading. [0004] Such as figure 1 As shown, the existing large-scale silo group loading system includes: silo group 10 , unloading trolley 20 , and feeder 30 . The silo group 10 is composed of silos 11 , 12 , 13 . . . silos N (N is a positive integer) and other silos connected in sequence. The unloading trolley 20 fetches materials from the raw material silo, moves along the running tra...

AI Technical Summary

Problems solved by technology

[0008] However, the existing system for judging the position of the unloading trolley has many disadvantages

For example, the existing system cannot comprehensively detect the location information of the unloading trolley. The unloading trolley 20 must be within the detection range of the sensor switch for the sensor switch to work; at the same time, the existing system cannot obtain the current location of the unloading trolley 20 exercise state
