Program overview
Traditional warehouse logistics management systems usually use bar code labels or manual documents to support the management of their own logistics links. The detailed process includes: printing orders, picking, merging baskets, picking, scanning inspection, scanning packages, Sorting, moving parcels, order delivery, as well as allocating sorting, allocating parcels, moving allocating boxes, allocating and delivering, returning to the factory packaging, returning to the factory and other processes, warehouse logistics industry inbound and outbound, quantity inventory, often consumes inventory Managers spend a lot of time using the active label technology of Xiaowang Technology to make everything automated, which is convenient and fast and prevents errors.
The intelligent logistics management system launched by Xiaonet Technology, the warehouse management plan is composed ofelectronic label, Receiver, cloud platform.
Warehouse management
Install a receiver (WGT2408Z-R) at the entrance of the door. When new items are put into the warehouse, install an RF tag on each item. Passing through the door, the receiver reads the ID number of the RF tag (the ID number of each tag is not Same) as the inbound record, the second time the receiver reads the same ID number as the outbound record.
Inventory count (online status report)
The tag sends data every 3 seconds. The receiver receives the data and sends it to the PC gateway. The PC gateway records the ID number of each item, counts the number through the ID number, and displays it on the computer through the host computer software.
System indicators
Maximum number of tags: 2000;
The farthest acceptance range of the label: 100 meters;
The maximum transmission distance between the receivers: 4.5 kilometers @5dbi antenna, 6 blocks through the wall;
Label battery life: 3 years;
Core technologies
Cellsnet wireless routing protocol
Cellsnet is an intelligent routing protocol for ZigBee wireless network that Guangzhou Xiaowang Technology began to develop in 2009 and formally applied for a national patent in 2011. It is a network protocol designed based on the network characteristics of street lamp systems. It belongs to the Mesh network technology in wireless sensor networks. Compared with traditional routing protocols, Cellsnet has a number of excellent technical parameters:
Peer-to-peer network: all nodes have the same function, good redundancy, and convenient installation and construction;
Easy to use: automatic routing, users do not need to care about the network structure and operation process, directly send data;
Fast communication speed: “Distributed calculation TQ balanced routing algorithm” is adopted, and the routing time is short;
Fast transmission speed: the first level routing and forwarding time is <15ms;
Large network capacity: Supports up to 65535 nodes.
The wireless peer-to-peer network technology belongs to the “Xiaowang Think Tank” technical innovation point number P001 project: Cellsnet sensor network networking protocol stack.
Note: “Xiaowang Think Tank” is a plan for Xiaowang’s electronic technology, management, and process technology innovation points. The technological innovation points that have been achieved are as follows:
P001: Cellsnet sensor network networking protocol stack;
P002: 2.4Ghz extended frequency band;
P003: User experience;
P004: Multi-level voice communication;
P005: Dual antenna technology;
P006: Low power consumption (sleep strategy, fast sleep and wake-up, power adaptive adjustment);
P007: Indoor positioning technology;
P008: Basic research on ZigBee IC
P009: ZigBee Pro protocol stack
Others belong to the company’s internal pre-research projects and are inconvenient to disclose;
A complete product chain provides support for the solution
Xiaowang Technology has been specializing in IoT technology since the beginning of 2009, from radio frequency design to wireless networking protocol, and from the needs of customers from all walks of life across the country, it has developed a variety of wireless technology products to meet the needs of industry applications. Show. And use these products to provide customers with solutions such as smart lighting, automatic meter reading, wireless indoor positioning, and warehousing logistics management.
Low-power technology
Low power consumption technology is a research technology of “Xiaowang Think Tank” (No. P006: Low power consumption (sleep strategy, fast sleep and wake up, power adaptive adjustment) According to research findings, the factors that affect the power consumption of electronic tags are not the intuitive working current (or working power consumption), but the sleep current and burst work cycle, because most of the time the electronic tags are in a sleep state, Xiaonet Electronics has achieved 3μA sleep current and 1.16ms burst duty cycle.
