Description

Intelligent work or material rest control system that high compatibility was easily maintained Technical Field The invention relates to the technical field of industrial automation and intelligent storage, in particular to an intelligent material rack control system for storage and sorting of materials in a warehouse and a production line and a core hardware implementation scheme thereof. Background In modern warehouse logistics and intelligent manufacturing, the intellectualization of the material rack is a key for improving material management efficiency and reducing manual errors. Traditional work or material rest relies on manual identification and record, and inefficiency and easily makeing mistakes. Although some existing intelligent material racks realize the basic lighting indication function, the core hardware system of the intelligent material racks has obvious defects, and the intelligent material racks mainly show the following aspects: The hardware configuration and maintenance are complicated, and a signal acquisition board (or IO board) usually depends on a physical dial switch to set an address. This approach is prone to communication failure due to dialing errors and poor switch contact. When the board card is replaced or newly added, manual dialing setting is needed, the operation is inconvenient, the implementation in a dense material rack is difficult, and the maintenance cost is high. The detection reliability is poor, the material detection mostly adopts a simple photoelectric switch, only can carry out high-low level judgment, is easily interfered by factors such as ambient light (especially natural light) change, light reflection, dust and the like, and has high false alarm and missing report rate. The lack of a compensation mechanism for the performance attenuation (such as infrared light source aging) of the sensor reduces the detection precision after long-term use. The system has low integration level and expansibility, single function and usually only has the function of lighting. If the functions of voice prompt, multicolor alarm, linkage with a novel picking label (such as a lamp-shooting button label) and the like are required to be added, an external independent module is required, and the system is complex, the wiring is disordered and the compatibility is poor. The network has weak adaptability, the communication mode is single, only wired or single wireless connection is usually supported, the network cannot adapt to dynamic scenes such as moving skip cars and the like, and the network has insufficient stability in complex industrial wireless environments. The operation and maintenance mode is backward, firmware upgrading and parameter calibration are required to be carried out through a local USB flash disk or a connecting wire, remote batch operation cannot be realized, and the equipment maintenance and function iteration efficiency is low. Therefore, the development of the intelligent material rack core hardware system with high compatibility, high reliability, easy maintenance and rich functions has important practical significance.
