Food is of paramount importance to the people, and food security is the cornerstone of national security. On November 17, 2021, the National Grain and Material Reserves Administration released the "Six Major Improvement Actions" for implementing the high-quality grain project during the 14th Five Year Plan period. By 2025, the new standard grain warehouse capacity will be increased by 20 million tons, and the annual increase in high-quality grain production will be over 10%, indicating the importance that the country attaches to grain.

Our country has been fighting against corruption and promoting integrity. In the field of grain purchase and sales, we have also investigated and dealt with a group of audacious and insatiable grain warehouse "rats". Most of the locks in grain depots are traditional mechanical locks, which not only have poor anti-theft performance, but also have keys that are easy to copy and are difficult to manage. Manually registering the opening and closing of lock records is not only prone to errors but can also be falsified, and is no longer a good choice nowadays.

The passive dual channel intelligent padlock is made of 316L stainless steel material, and the lock core adopts a dedicated keyhole design, AES digital encryption technology, and 360 ° idle technology to prevent technical opening. 9mm thick locking beam with strong resistance to damage. There is no power supply inside the lock, no maintenance required. Dual channel, dual system, ensuring that when one channel fails, the other channel can be unlocked.

The smart key management cabinet is used for the management of smart keys. Facial recognition automatically unlocks, matching corresponding smart keys and unlocking permissions based on facial recognition results. The smart key can set the unlocking duration and number of times, and after expiration, it will be restored to no permissions without the risk of being copied. All data will be uploaded to the lock management system in the form of logs, and there will be no legal modification or deletion, which can be viewed at any time.

The intelligent lock management system+passive dual channel intelligent padlock+intelligent key management cabinet can be used for grain monitoring warehouse doors, drug and equipment warehouse doors, grain warehouse gates, etc. The intelligent key and lock have a one to many relationship, and only a small number of keys are needed to manage all passive intelligent locks in the factory area, which is efficient and convenient. Urge the staff to take the daily inspection of the grain depot more seriously, and when faced with "air grain" and "revolving grain", they can also provide real and effective data as evidence.

This system digitizes lock management, simplifies the process of opening and closing locks and receiving and returning keys in grain depots, improves the safety of grain in grain depots, and the simple operation method allows staff to quickly get started.
