Intelligent compact shelf control system and control method

Abstract

The invention provides an intelligent compact shelf control system and control method. The system comprises an archive management computer, a user terminal and a plurality of compact shelf units respectively arranged in rooms. Each room is provided with a compact shelf unit; each compact shelf unit comprises an information repeater and a plurality of compact shelf zones; each compact shelf zone comprises a main column control unit and a plurality of mobile column control units; the main column control units communicate with the mobile column control units through a CAN bus; the main column control units in the same room are connected with the information repeater in the room where the main column control units are located through the CAN; the information repeater in each room is connected with a communication network; and the archive management computer and the user terminal are also independently accessed into the communication network. The communication network and a CAN bus technology are utilized for optimizing the topology structure of the intelligent compact shelf control system so that the system parallel work capability and remote control capability are improved, and the complexity of system wiring is reduced.

Description

technical field [0001] The invention belongs to the technical field of dense rack control, and in particular relates to an intelligent dense rack control system and a control method. Background technique [0002] The compact rack is a device widely used in banks, archives, libraries and other enterprises and institutions for storing archives. At present, the widely used compact racks are manual compact racks. The operating load of this kind of compact racks is proportional to the number of racks in each group of compact racks. Especially for compact racks with a large number of columns, the handle has a large workload, The operation of the compact shelf is time-consuming and laborious, and the file data access speed is low. [0003] Therefore, in order to facilitate operation, there has been an intelligent compact shelf in the prior art. The intelligent compact shelf associates the mobile operation of the compact shelf with the file management computer by adding additional ...

However, in the prior art, RS-232 / RS-422 communication is used between the file management computer and the main row control unit. Since RS-232 / RS-422 is point-to-point communication, the file management computer and the main row control unit need to Direct connection has the following disadvantages: (1) the layout of the file management computer and the compact shelf has brought limitations, and the file management computer cannot be freely arranged; (2) especially when the compact shelf is divided into several areas and arranged in different rooms , For example: Arrange the compact shelves in 3 rooms, each room is composed of 3 compact shelf areas, each of which is composed of a column of main row control units and a number of mobile control units, in order to realize file management computer-to-many For the control of multiple areas in one room, the common solution is: the file management computer is connected to the main column control unit of the compact racks in each area through multiple independent RS232 / 422 interfaces, so as to realize the unified management of all the compact racks by one file management computer

Therefore, the file management computer uses multiple RS232 / 422 interfaces to independently control the block of the compact shelf. Due to the limited number of computer serial ports, the number of the block of the compact shelf is limited, and the scalability of the system is restricted; independent wiring of each compact shelf block, resulting in complicated system wiring

(3) The compact shelf can only be connected to one file management computer, and any file entry and exit operations must be realized through this file management computer, which reduces the efficiency of file entry and exit management

This method is centralized management, the user terminal cannot directly operate the compact shelf, and the file management computer is the core of the entire system. Therefore, once the file management computer fails, the entire compact shelf control system will not be able to work normally.
