When the material level of the storage bin is too low, the production system is broken, the normal production on the site can be influenced, and irretrievable loss is caused to enterprises in serious cases, so that the monitoring of the material level of the storage bin is particularly important. The existing stock bin device is fed from the top and is sealed all around, so that the internal material quantity cannot be directly observed, and the existing stock bin device is not favorable for visual observation of workers due to poor operation site environment and more dust. At present, the material level is mostly detected by adopting a material level meter, but the material level meter is a more precise instrument, so that the price is higher, and the popularization is inconvenient; on the other hand, the monitoring of the material level by the material level meter is not completely and accurately influenced by the field environment, false alarm occurs frequently, and the actual production cannot be directly influenced by the fact that an operator can accurately acquire material level information in actual production.

The feed bin monitoring that uses at present mostly is the inside charge level indicator that sets up of feed bin, and connection control system monitors. However, this system is extremely complex and expensive, and the level indicator is a relatively delicate instrument, which is vulnerable.
