Grain warehouse personnel positioning system

In grain storage and management, as a key facility, the safety and efficiency of grain warehouses directly affect the quality of grain and the operating costs of enterprises. The internal environment of the granary is complex, storing a large amount of grain, and personnel and vehicles are frequently active. In addition, there may be safety hazards such as harmful gases and dust. Therefore, efficient and accurate positioning management of personnel and vehicles in the granary is particularly important.

1. personnel securityThe personnel activity area and vehicle driving area in the granary are intertwined, which can easily lead to collisions between people and vehicles. The positioning and collision prevention of vehicles with nearby personnel during operation can significantly reduce such risks.

2. work efficiencyBy monitoring the positions of personnel and vehicles in real-time, the workflow can be optimized, waiting time and resource waste can be reduced, and overall work efficiency can be improved.

3. Management optimizationManagement personnel can quickly respond to emergencies based on real-time data, develop scientific and reasonable scheduling plans, and improve management level.

4. Collision warningTimely warning of potential collision risks during vehicle operation, avoiding accidents, and ensuring the safety of personnel and property.

As shown in the following figure,Grain warehouse personnel positioning systemIt is mainly composed of two parts: one is the indoor wireless positioning base station, which is used for indoor positioning of people and vehicles. The positioning data is transmitted to the positioning server through 4G positioning terminals for people and vehicles, and then solved. The second is the positioning terminal that personnel need to wear, and the vehicle needs to be equipped with a vehicle mounted integrated positioning collision avoidance terminal. The vehicle mounted terminal needs to be matched with an audible and visual alarm. People and vehicles use UWB for real-time distance measurement. When the collision avoidance distance is less than the set distance, people and vehicles will sound an alarm to achieve the collision avoidance function.

Grain warehouse personnel positioning systemSatellite positioning technology is used outdoors, high-precision UWB positioning technology is used indoors, and satellite positioning technology is used outdoors to achieve precise positioning of personnel in grain storage vehicles, and seamless switching between indoors and outdoors. In addition, the fusion of UWB technology is adopted to achieve collision warning function for people and vehicles. The characteristics of the solution are as follows.

1: The outdoor use of Beidou satellite positioning scheme does not require the deployment of additional equipment, and the satellite positioning accuracy can reach 1 meter;

2: Indoor use of UWB ultra wideband positioning technology, with a positioning accuracy of 10-30cm

3: It can achieve high-precision positioning both indoors and outdoors, while also providing collision warning for both people and vehicles.

4: Real time refresh of location, default refresh once per second.

The significance mainly includes the following aspects:

Improving safety: Grain warehouses are important places for the import and export of goods, with dense population and busy traffic, making them prone to collisions and traffic accidents. Through the positioning and collision prevention technology of grain warehouse personnel, the position and movement trajectory of personnel can be monitored in real time, and collisions and traffic accidents can be detected and prevented in a timely manner, improving the safety of grain warehouses.

Improving efficiency: The personnel positioning and collision avoidance system in the grain warehouse can monitor the position and movement trajectory of personnel in real time, effectively dispatch and manage personnel, and improve the operational efficiency of the grain warehouse.

Cost reduction: By using the grain warehouse personnel positioning collision avoidance system, the occurrence of personnel collisions and traffic accidents can be reduced, and the cost of accident handling and compensation can be lowered.
