Description
Technical Field
The invention relates to a lockpin movement measurement type RFID recording lock for a logistics circulation box, which consists of lockpins for the logistics circulation box, a lockpin axial displacement measuring device and an RFID module. The RFID recording lock for the logistics turnover box has the obvious characteristics of recording the occurrence time and duration of opening and closing the turnover box by measuring the movement of the lock pin besides the functions of common RFID sensing and information. The RFID integrated with the new function of unpacking record can form an RFID record lock logistics turnover box, is applied to various processes of standardization and universality of logistics storage inside an enterprise, long distance and short distance outside the city of the enterprise, an e-commerce distribution center and an express company, the express company and an express delivery person, and has the advantages of high safety, high integration, low power consumption and the like, and belongs to the field of transport packaging products and logistics conveying equipment.
Background
Containers change the world, customers need 'door to door' freight transportation services, containers provide a solid foundation for seamless connection of sea, land and air combined transportation, and containers are the foundation of modern logistics. The container transportation accounts for over 60 percent and 20 percent respectively in international and domestic trades in China. Although a large amount of energy is consumed in the transportation process of the container with the dead weight of several tons, the transportation cost is reduced due to the advantages of loading, unloading and transportation efficiency, safety, storage performance, standardization and the like of the container.
The transport package, also called as external package, mainly uses corrugated paper box, and is mainly aimed at reducing damage to product in the course of transport and circulation as far as possible, ensuring product safety, convenient for transport, storage, transportation and loading and unloading and quickening cross-over point test. Transport packaging is not an internal package (e.g., carton, plastic bag, glass bottle, plastic bottle, etc.) that affects the quality performance of the product and the packaging decoration. The use amount of massive small-size corrugated cases and buffer materials (shock insulation bubble films and buffer air bags) which are packaged after electronic commerce distribution is increased sharply, and the problem of secondary transportation and packaging which is newly generated along with an electronic commerce mode is that the transportation and packaging mode is changed greatly.
At present, the turnover box inside or outside an enterprise is a combination of an integral plastic surface and a plastic shell. With the development of personalized customization of market-sold products and small-batch production of the products, the turnover box with the informatization function is needed for reducing the consumption of corrugated cartons and realizing the rapid logistics of goods from manufacturers, e-commerce to consumers. In various major electronic commerce in China, some companies only pack small articles into plastic turnover boxes according to destinations after small corrugated boxes and plastic packaging bags are packed, so that the transport, loading and unloading are facilitated, but the turnover boxes are not provided with RFID electronic tags. Other e-commerce companies and express companies pack the goods, which are wrapped, into snakeskin bags according to destinations.
The patent application (patent name: combined rubber-plastic corrugated board and RFID turnover box made of the same, application number: CN201610644802.5) proposes that the RFID module is adopted to control the electronic lock coil of the logistics turnover box, thereby realizing the requirements of safety and authenticity of opening and closing of the box cover. But increased the electronic lock, commodity circulation turnover case cost increases, and effective volume of carrying cargo reduces, and electron device's power consumption especially increases, the reliability reduces.
The locking is for unlocking, and the locking action is only one means, not a low-cost means. The anti-counterfeiting and anti-theft functions of the carton sealing tape show that the opening behavior can be found even if the sealing tape is removed after being heated and is adhered again. Therefore, for non-valuables, such as commercial and super goods, the safety and authenticity of goods in the logistics circulation box can be guaranteed only by fully ensuring that the opening behavior of the logistics circulation box is found and traced in the storage and transportation processes to form the control function.
