Wireless intelligent sorting system based on Internet of Things technology positioning

Abstract

The invention discloses a wireless intelligent sorting system based on Internet of Things technology positioning. The wireless intelligent sorting system comprises at least one main station, at least one sub-station and at least one intelligent sorting small vehicle. The small vehicle travels along a fixed track, the starting point and the end point of the fixed track are coincident, the main station and the sub-station are arranged next to the fixed track, RFID tags are arranged on the main station, the sub-station and the intelligent sorting small vehicle, a first RFID reader-writer is arranged on the intelligent sorting small vehicle, the intelligent sorting small vehicle is connected with the first RFID reader-writer, the main station is provided with a server, a second RFID reader-writer, a wireless receiver and a scanner, the server is connected with the wireless receiver and the scanner, the server, the second RFID reader-writer and the intelligent sorting small vehicle are in wireless connection through the wireless receiver, the sub-station which each object belongs to is preset in the server, the small vehicle reads RFID tag information of the sub-station when passing through the sub-station, whether the sub-station is a target sub-station or not is judged, and if the sub-station is the target sub-station, unloading is conducted. The wireless intelligent sorting system based on Internet of Things technology positioning is low in cost, high in flexibility, simple in logic and low in maintenance cost.

Description

technical field [0001] The invention relates to the technical field of warehousing and logistics, in particular to a wireless intelligent sorting system based on Internet of Things technology positioning. Background technique [0002] The work of warehousing and logistics is hard work, the turnover rate of employees is high, and the labor cost remains high. At present, the cost of automation equipment on the market is high, and small and medium warehousing or distribution warehouses cannot bear such a high cost. The number of small and medium warehousing without automation in the market accounts for at least 80% of the total, and they are also facing increasing labor costs. Therefore, in order to solve the problem of labor cost, there is an urgent need for an intelligent sorting system that can replace manpower at low cost. [0003] Disadvantages of automation of existing logistics storage sorting machines: [0004] 1) High cost: A cross-belt sorting line costs tens of mil...

AI Technical Summary

Problems solved by technology

[0004] 1) High cost: A cross-belt sorting line costs tens of millions for imports and millions for domestic production. The annual maintenance cost ranges from hundreds of thousands to hundreds of thousands, which is difficult for small and medium-sized logistics companies and warehouses to afford. ;

[0005] 2) Poor flexibility: The existing logistics sorting machine assembly line is planned according to the business form and mode. Once the plan is formed, it is difficult to change it, because the total number of sorting ports of the assembly line needs to be determined in advance. Once the sorting port is determined, it is very difficult to follow up It is difficult to increase and decrease, because it will be limited by site planning, and special areas need to be divided during construction. This area can no longer be used for other purposes, resulting in increased fixed costs;

[0006] 3) Complex logic: the existing sorter assembly line will consider many path judgments and task judgments, which complicates the logic of the assembly line, requires a lot of sensors for judging tasks, complicated wiring, and local failures will stop the entire automatic line from operating ;

[0007] 4) High maintenance cost: the existing automatic line needs to be maintained and repaired every year, which is costly and requires a huge support team to support and maintain
