摘要：Internet of Things of course build a very good blueprint, but the current global situation to the development of things facing many problems, such as the Internet of Things, you must first memory bank to embed electronic tags on all items, and need to install a number of read equipment and a huge amount of information processing system, which will inevitably lead to a lot of capital investment. The items attached storage will lead to the rise in cost of goods, cost has not yet dropped to the popularity of the premise, the development of the Internet of Things will be limited.

er、faster and cooler. More faster means faster response speed; colder refers to the power of a single device. But smaller is not without limits.
3 .Middleware technology
3.1 Middleware Profile
Middleware is one of the basic software categories; belong to the scope of reusable software. As the name suggests, the middleware is in the middle of the operating system software with the user's application software.
Middleware in the above operating system, network and database application software lower the overall effect is in the top of the application software to run the development environment to help users with flexible, efficient development and integration of complex applications. IDC expressed in a number of middleware definition more widely accepted: middleware is an independent system software, or services program, distributed application software with this software to share resources between the different technologies, in the middle in client-server operating systems, management of computing resources and network communications.
RFID middleware is to achieve data transmission between the RFID hardware and application systems, filters, an intermediate data format conversion program, a variety of data read by the RFID reader, through the middleware extraction, decryption, filtering, format conversion, import management information systems, program interface for the operator to browse, select, modify, query and response through the application of the system. Middleware technology also reduces the difficulty of application development, developers do not need to directly face the underlying architecture, and make calls through the middleware.
RFID middleware is a message-oriented middleware; information is passed to one or more program modules in the form of a message from a program module. The messages can be asynchronously transmitted; the sender does not have to wait for a response. RFID middleware on the basis of the existing enterprise application middleware development, with its own application features to further expand and deepen the enterprise application middleware in the enterprise. Its main features are:
(1) Independence. RFID middleware independence between the RFID reader and back-end application does not depend on an RFID system and application systems, and can connect with more than one RFID reader and multiple back-end application in order to reduce architecture and its complexity.
(2) Data Streams. It is the most important part of the RFID middleware, its main task is the entity object format into the information environment of virtual objects, and data processing is the most important RFID functionality. RFID middleware with data collection, filtering, integration and transmission characteristics, so that the correct object information transmitted to the enterprise back-end application systems.
(3) The processing flow. RFID middleware is a messaging middleware function is to provide a sequence of message flow, data flow design and management capabilities. The need to maintain the data transmission path, data routing and data distribution rules in the system. Data security in data transmission, including the consistency of the data to ensure that the data received by the recipient and sender. But also to ensure the security of data transmission.
