As a medium for daily storage of goods, racks are often used as transfer stations or long-term storage for industrial products, food and beverages. There are many types of racks, including pallet racks, shelf racks, drive-in racks, cantilever racks, gravity racks, mobile racks, etc.
Every year, there are countless accidents caused by hidden dangers in warehouses. Among them, accidents caused by inferior shelf equipment or non-standard design or use have caused many companies and personnel to pay a heavy price. So how to prevent safety accidents caused by the collapse of storage shelves?
Today, through the cases and solutions of Yili smart shelves, we will let you know the specific application of Zhinuo NB-IOT wireless tilt sensors in the smart shelf safety monitoring system:
As early as August 2018, a batch of NB-IOT wireless tilt sensors had been successfully installed in one of the warehouses of Yili smart shelves. In the subsequent period, several warehouses were installed. After nearly half a year of operation and use, Yili also gave this shelf tilt monitoring system a high evaluation and full affirmation.
The main problems solved in this solution (problems faced by most shelf users):
1. Daily inspections rely on visual observation of shelf safety status, and abnormal shelf status cannot be discovered in time
2. There is no device to measure the inclination of the warehouse shelves, and it cannot be discovered in time when the shelves are aged and tilted
3. The shelves are frequently stored and retrieved, and the status is aged, and they can no longer meet the initial safety standards
4. When the forklift collides with the shelf, the shelf tilt cannot be discovered in time, posing a safety hazard
5. The initial deviation of the shelf position is tilted, and the deviation is further increased due to long-term load, which exceeds the range allowed by the safety standards and cannot be discovered by daily visual inspection
Solution:
The NB-IOT-based IoT tilt sensor (model ZCT330E-SWP-N) developed and produced by Zhinuo Technology for Yili Group can be fixed on the shelves at four corners to monitor the angle changes of the shelves in all directions. The local deformation and tilt that cannot be observed by the naked eye can be displayed in real time with data. On the one hand, it can timely discover and replace shelves with quality problems that have been deformed; on the other hand, it can realize shelf safety management, and timely alarm can be issued for overturned shelves and handled on the spot.
The wireless tilt sensor developed by Zhinuo Technology provides 24-hour all-weather safety and anti-dumping monitoring. Through the mobile APP terminal, you can view the tilt status of the shelf in real time. When the shelf alarms more than 1.2 degrees, the mobile phone will sound an alarm. The client software independently developed by Zhinuo Technology is powerful. In addition to automatic alarm, it can also display the specific location (longitude, latitude). The software background can view historical data and refine the data changes to 5-10 minutes.
The IoT inclination sensor based on NB-IOT developed by Zhinuo Technology is not only used in manhole covers, smart light poles, billboards and other fields, but has also started a new journey in the field of smart shelves. This will be the choice of smart security and smart warehouse owners.
