Control method and control system of compact shelving system

Abstract

The invention discloses a control method and a control system of a compact shelving system which is easy to implement, has a simple structure and is safe and reliable. The method comprises the following steps: detecting current change (sudden change) according to the change of the current of a driving motor when a compact shelving is extruded at a normal operation state; analyzing and detecting through a safety protection unit; and controlling to whether execute an emergency stop operation of the compact shelving or not by the safety protection unit. The control system comprises a safety protection unit and a current detector; and the safety protection unit is used for analyzing and detecting; and the safety protection unit is used for controlling whether the emergency stop operation of the compact shelving is carried out or not. The control system comprises the safety protection unit and a current detector; and the safety protection unit is used for analyzing and detecting a current signal which is output by the current detector, is extruded when the compact shelving is operated or interfere the driving motor to suddenly change.

Description

technical field [0001] The invention relates to a control method of a compact shelf system and a control system thereof. Background technique [0002] As an important part of the modern centralized storage management system of files, the compact shelf is an important part of the modern centralized storage management system. With the continuous development of automatic control technology, the automation control degree and concentration of the intelligent compact shelf are getting higher and higher, and the composition is becoming more and more complex. The storage management The function is getting stronger and stronger. This puts forward higher requirements for the safety and reliability of the compact rack system. Due to the imperfect and unreasonable control and detection means, methods and structures of the existing intelligent compact racks, their safety is still insufficient. If the infrared human body sensor is installed at the entrance and exit of the shelf, the real...

This puts forward higher requirements for the safety and reliability of the compact rack system. Due to the imperfect and unreasonable control and detection means, methods and structures of the existing intelligent compact racks, their safety is still insufficient. If the infrared human body sensor is installed at the entrance and exit of the shelf, the realization of its safety function is realized through the memory of the number of people entering and exiting through the controller. When entering at the same time or failing to meet the above necessary conditions due to special reasons, or when there is a problem with the detection device that plays a key role, safety problems may arise

[0003] In particular, most of the existing smart rack control systems use a lot of detection elements or devices in order to pursue powerful, omnipotent, all-round, so-called perfect, and humanized control, but because these detection devices In terms of signal detection and comprehensive processing, the reliability of the detection signal, as well as the selection and application of detection parameters are not scientific and rational enough, which makes the reliability, stability, safety, operability and operation of the entire control system Efficiency is affected to varying degrees, and even wrong judgments and wrong actions occur, leading to system safety accidents
