Description

Agricultural product logistics storage management device based on superposition and positioning of multiple spatial location information

technical field

The invention relates to the technical field of logistics storage management, in particular to an agricultural product logistics storage management device based on superposition and positioning of multiple spatial position information.

Background technique

Warehousing is an important part of modern logistics, plays a vital role in the logistics system, and is the focus of manufacturers' research and planning. Efficient and reasonable three-dimensional storage can help manufacturers speed up the flow of materials, reduce costs, ensure smooth production, and achieve effective control and management of resources. Automated three-dimensional warehouse (AS/RS) is composed of three-dimensional shelves, tracked roadway stacker, inbound and outbound pallet conveyor system, size detection barcode reading system, communication system, automatic control system, computer monitoring system, computer management system and others such as A complex automation system composed of auxiliary equipment such as wire and cable bridge distribution cabinets, pallets, adjustment platforms, and steel structure platforms. Use the first-class integrated logistics concept, adopt advanced control, bus, communication and information technology, and carry out warehouse entry and exit operations through the coordinated actions of the above equipment. The three-dimensional warehouse has become an indispensable warehousing technology for enterprise logistics and production management due to its high space utilization rate, strong in-out and out-of-warehouse capabilities, and the use of computers for control and management, which is conducive to the implementation of modern management by enterprises. enterprise's attention. At present, the technologies used for indoor positioning in logistics warehouses include WIFI, ZigBee, RFID, etc. Satellite navigation mainly uses GPS, combined with the location information recorded in RFID to manage the location in the database.

For example, the application number is 201410039885.6, which is named as an invention patent of a logistics warehouse management device based on the superposition and positioning of multiple spatial positions.

The invention uses Beidou satellite or GPS to locate the target goods or target points, and obtains their absolute coordinate values (longitude, latitude, altitude), which can be used as basic data for subsequent modeling and basic data for searching for goods. The second is the navigation function for personnel or machines. Wireless network nodes are deployed on each shelf in the warehouse according to certain rules. The wireless networks used include GPRS, ZIGBEE and WIFI, which will be automatically switched according to the strength of each wireless network signal. Always maintain the best navigation effect. When the planned route for the storage location of the goods or the optimal vacancy is generated, usually special warehouse staff or automatic storage and retrieval vehicles (equipment, etc.) will go to the corresponding target location according to the planned route to perform corresponding operations (pick up, release goods, etc.) , inspection, etc.). The wireless nodes deployed everywhere will monitor the arrival position of people (or equipment) in real time. If they deviate from the planned route, they will be reminded in time through wireless messages, prompting people (or equipment) to adjust their travel routes, and avoid getting lost or lost in the warehouse. The occurrence of detours makes the effect of route planning optimal and the plane space positioning model stored in the storage module mainly converts the absolute latitude and longitude in the satellite positioning data into the distance between the warehouse and the plane reference point, so as to further know The container it is in (indicated by the container number) and its horizontal position on the container (indicated by the pallet number). The model is established by the plane space positioning unit in the embedded system and performs data conversion in it. The process is as follows: first select the plane datum point, and according to the actual situation, the entrance of the warehouse can be set as the datum point; The longitude and latitude of the point, by calculating the difference between the longitude and the latitude of the target point and the reference point, and taking the square root of the square sum of the two differences, the distance from the target point to the reference point is obtained; then the edge of each container is calculated For point positioning, use the above method to calculate the distance between the edge point and the reference point. The distance between all the edge points of a container constitutes the plane positioning range of the container. If the target point falls within the scope of a certain container, the container number of the target point can be determined; according to the size of the pallet on a horizontal plane and the position of the reference point of the container, the level of the target point on the container can be obtained Location.
