Abstract

Logistics is a very important link in the supply chain of flow of goods, has an important role in the economy, and storage is the key link in modern logistics. In the process of warehouse management activities will produce large amounts of storage information. This information is often associated with the warehouse orders, cargo warehousing, cargo management and the occurrence of outbound goods, general with frequent data operation and data volume and complex information content. Efficient and reasonable storage can carry on the effective control and management to the goods. How to reduce inventory investment, strengthen the inventory control and supervision, improve the distribution of space, personnel and equipment and shorten inbound and outbound process and inspection time is the key to reduce costs and improve their competitiveness. Information technology has become the important pillar of storage technology, the combination of automatic warehousing and information acquisition decision system, and the use of wireless radio frequency technique makes the storage in the direction of the intelligent development. IOT (Internet of things) pointed out the direction for the development of intelligent warehouse system is put forward, it is linked to the Internet, the goods that all items can be remote sensing and control. Therefore, research content intelligent storage system is of great significance. 1 The Internet of things

Internet of things was proposed in 1999, is the concept of Internet of things is the network connection objects, its definition is: through the radio frequency identification RFID (radio frequency identification), infrared sensors, global positioning system (GPS) and information sensing equipment such as the laser scanner, according to the contract agreement, connect the item with the Internet for information exchange and communication, in order to realize intelligent identification, location, tracking and monitoring and management of a network. Discussing the Internet of things, often referred to the concept of M2M, M2M can explain become people to people, people to the machine, machine to machine.

1.1 Internet network system

The Internet of things has been in logistics, warehousing, guard against counterfeit products, intelligent building, street lamp management, smart meters and urban water network infrastructure and health care and other fields. But as a result of the present stage of research and application of the Internet of things is still in its infancy, so no unified standard for the Internet of things, and to further study the architecture of Internet of things, you must first research the Internet of things has been build application systems and application examples. At present, the Internet of things has not been widely accepted by a system structure, also does not have a unified technical standards and protocols, is the most representative IOT architecture is Europe and the United States supports the electronic product code of EPC (electronic product code) Global Internet architecture and Japan's Ubiquitous ID (UID) Internet system. IOT perception layer includes sensors, data acquisition equipment and data before access to the gateway of the sensor network and intelligent terminal. The network layer is established on the basis of the existing mobile communication network and the Internet, through a variety of devices connected to the mobile communication network and Internet access, it also includes information storage, query and network management functions. Internet of things application layer using after analysis and processing of sensory data, to provide users with specific services. 1.2 Based on EPC system of Internet of things

At present, the Internet of things I OT application are mostly based on radio frequency identification RFID electronic product code of the EPC network. RFID is a non-contact automatic identification technology, its working principle is: the use of radio frequency electromagnetic wave, the reader and classified tracking mobile objects between the RFID tag is attached to) on (item, through space coupling (alternating magnetic field or electromagnetic field) no contact information, and through the passed the identification information to achieve. EPC IOT system main components include: EPC labels, EPC is a worldwide, the standard definition of product digital identification, storage in the tag. RFID reader, it is a kind of using RFID technology to read information stored in electronic tag and passed to the logistics warehouse management information system of device. The EPC middleware, this is a set of program modules with special properties or services, users can customize according to certain application requirements and integration in the EPC middleware different features, one of the most important part is the

application layer event the ALE (application layer events), it is used for processing the application layer related events. Information service (EPC as-is), EPC - IS including two functions, one IS to store the information of the EPC middleware processing, 2 it IS to query the relevant information. Object name service ONS (objects name service), similar to the domain name server, the information can be used to point to a store of EPC middleware information - IS the server. 2 Intelligent logistics warehousing system

Intelligent logistics warehousing system should not only be able to put in storage management, warehouse management, mobile library, inventory management, allocating and return management and reporting analysis, but also to monitor the position offset in the goods and the surround environment of temperature, humidity, video monitoring and fire alarm on warehouse, etc. Intelligent logistics warehousing system includes both hardware and software. Software part mainly for the warehouse management system, it shall, in accordance with the business requirement of the logistics, warehousing, information, resources, behavior, manage and allocate goods and staff, etc, to make them effective operation reasonably, and make the whole system and the Internet relative to meet. Hardware part mainly supports warehouse management system of a variety of hardware equipment and a variety of tools, etc. Intelligent logistics warehousing system of information release of the goods in to the Internet of things. Over the Internet, information query, order the goods, whether goods can be easy to move goods or remote operation and monitoring. The goods in intelligent storage system processing steps are as follows. Put in storage process, the first use of RFID electronic tag for inbound identity verification, and to transfer the information of the goods to the data center to register the goods, and distribution route to calculate the shelves positions, and then send a forklift on instruction, tracking and locating the goods, to ensure that the goods to the correct positions. Inventory management, inventory goods for internal operation process, mainly including guidance and in place of goods inspection, the goods number automatic identification and automatic calibration, distribution, the reservoir is correct, returns, processing, transfer processing, packaging, handling and disposal, and other functions. Outbound process, first brought the people to the warehouse for outbound application information system, intelligent warehouse management system according to the priority of goods information and positions, and then sent a forklift scheduling command, forklift truck reach positions to check the goods after the information is correct, began to transport goods. Each unit operation, between the

reader information the goods will be sent back to the data management center in a timely manner, when, and to determine the operation of each link is accurate and correct. 3 The research of intelligent warehouse system structure 3.1 WSN based on EPC and feasibility analysis

Wireless sensor network (WSN (wireless sensor network is composed of a large number of tiny sensor nodes deployed in monitoring area, through wireless communication mode to form a multiple hops self-organizing network system, its purpose is collaboration to perceive, collection and processing network coverage area perceived object information, and sent to management center. At present, the research of Internet of things has not been thorough, the connotation of Internet of things technology is the lack of professional research, some professional or non-professional reporting usually put the wireless sensor network (WSN and IOT confused, often called the Internet of sensor network in our country, but it is not the same as the wireless sensor network. Look from the network architecture and protocol, IOT and WSN is completely different. Look from the target feature, IOT is known objects detection and networking, and WSN is to detect the unknown things or its parameter information. But there are inseparable, RFID technology is one of the core technology of the Internet of things, the RFID module in the Internet of things can or combined with WSN complementary integrated sensor technology, so as to get goods in the logistics process of environmental parameters such as temperature and humidity, it can also through the WSN data transmission of the RFID reader, weaken the WSN sensor function; And in some extension of the WSN applications, the RFID protocols may also be a one of the wireless communication protocol, or detect known objects properties. At present, the existing intelligent warehouse management system based on EPC and logistics warehouse management system based on WSN demonstration case, but real to attain the request of \For intelligent warehouse management system based on EPC, like forklift and handheld devices such as portable reader, set up special wireless transmission network. For the warehouse management system based on WSN, due to the node cost is higher than the EPC tags, and node hasn't really realize miniaturization volume, making it not like the label on the surface, the movement has a great influence on items. Intelligent storage system based on EPC can be combined and WSN, combined with the system after the use of WSN for EPC. 3.2 Intelligent logistics warehousing system research design
