Multi-cell storage cabinet system

Abstract

The invention relates to a multi-grid storage cabinet system which comprises an upper computer, a plurality of control panels and a plurality of groups of grids corresponding to the control panels respectively, each group of grids comprises a plurality of grids, the control panels are connected with the upper computer through CAN buses, and the control process of the upper computer on the grids comprises the following following steps: S1, a control instruction is generated; s2, a digital CAN ID is generated, and a first character string is obtained; s3, a sequence number of the target cell in the digital form relative to the control panel is generated to obtain a second character string; s4, a third character string is obtained according to an operation command character string; s5, the first character string, the second character string and the third character string are connected in series to obtain a message, and the message is sent through a CAN bus; and S6, each control board passes through the message on the CAN bus and receives the message corresponding to the CADID to execute the message. Compared with the prior art, the system has the advantages of low failure probability and the like.

Description

technical field [0001] The invention relates to a locker system, in particular to a multi-compartment locker system. Background technique [0002] At present, the slot numbers of most multi-compartment multi-function lockers use a combination of letters and numbers as the unique identification mark, such as "A01" and "A02" for the A cabinet, "B30" for the B cabinet, and "B30" for the C cabinet. "C25" and so on, in order to operate each compartment, such as opening the door, turning on the lights, etc., an additional control panel is required. One control panel controls several compartments, and the entire locker needs several control panels to control together. If the host computer program wants to locate and operate a certain slot, for example, to open the door of A01, it needs to first communicate with the main control board controlling A01, and then tell the control board to open the door of A01 through commands. [0003] There are many options for the communication inte...

Problems solved by technology

[0003] There are many options for the communication interface between the upper computer and the main control board. The commonly used one is the RS485 serial port. Compared with other serial busses, such as RS232, TTL, and RS485, because they are differential signals, they are relatively strong in anti-interference and can be networked. Each node can set its own address, but in the actual use process, it is found that it still has the following defects: In the large-scale networked storage cabinet system, it is easy to control multiple slots at the same time. When the ports are controlled at the same time, because there will be data sending and receiving, it is easy to generate data conflicts, which will cause data loss and garbled characters, resulting in invalid control commands

In the existing technology, the large-scale dining cabinet system is generally divided into sub-modules, and each sub-module is partitioned and defined. At this time, if the user accidentally selects the wrong operation panel, the items cannot be taken out normally.

Or there are existing technologies that directly cancel the operation panel and use cloud services to identify partitions, but this method has poor user experience and has high requirements for the mobile communication network environment
