RFID development environment, what software and hardware are needed, for small and medium sized comp

1. RFID printer: RFID electronic tags need to be printed with RFID printers, and there are many RFID printer brands on the market, such as Zebra, Kecheng, etc.

2. RFID inventory machine: when you need to take inventory of fixed assets, you need to use RFID inventory machine to take stock of enterprise assets.

3. RFID reader: also known as "RFID reader", that is, wireless radio frequency identification, which automatically identifies the target object and obtains relevant data through the radio frequency identification signal, can identify high-speed moving objects and can identify multiple RFID tags at the same time, which is fast and convenient to operate. There are fixed and handheld RFID readers, and handheld RFID readers can be divided into low-frequency handheld RFID readers, high-frequency handheld RFID readers, ultra-high frequency handheld RFID readers, active handheld RFID readers, etc.

In addition to RFID devices, RFID management systems include:

1. RFID electronic tag: RFID electronic tag records the exclusive Hu Mu wide item Xinnai Xiangxi, which is used to paste or fix on the item, if it is used for metal material assets, it is necessary to select anti-metal material RFID electronic tag. If the asset has the characteristics of erosion, high temperature, etc., be sure to choose a label that meets the requirements to prevent detachment, embrittlement, magnetic induction, etc.

2. RFID fixed asset management software: RFID fixed asset management software is also indispensable for the whole system, which is used to manage, record and count the information.

In the specific application process of RFID system, the composition of RFID system will be different according to different application goals and application environment, but from the working principle of RFID system, the system is generally composed of signal transmitter, signal receiver, and transmitting and receiving antenna.

1) Signal transmitterIn the RFID system, the signal transmitter will exist in different forms for different application purposes, and the typical form is tag. The label is equivalent to the barcode symbol in the barcode technology, which is used to store the information that needs to be identified and transmitted, in addition, unlike the barcode, the label must be able to automatically or under the old and indiscriminate use of external forces, and the stored information is actively emitted. The tag is generally a low-current integrated circuit with a coil, antenna, memory and control system.

2) Signal receiverIn the RFID system, the signal receiver is generally called a reader. Depending on the type of tag supported, and the functionality completed, the level of complexity of the reader varies significantly. The basic function of the reader is to provide a way to transfer data to the tag.

In addition, the reader provides sophisticated signal status control, parity error checking, and correction functions. In addition to storing the information that needs to be transmitted, the label must also contain certain additional information, such as error verification information. Identifying data and additional information are organized together in a certain structure and sent outward in a specific order.

The reader controls the sending of the data stream through the additional information it receives. Once the information that arrives at the reader has been correctly received and interpreted, the reader decides through a specific algorithm whether the transmitter needs to resend the signal sent once, or knows that the transmitter has stopped transmitting, which is it"Command Response Protocol"。With this protocol, it is possible to effectively prevent multiple labels from being read in a very short time and in a small space"The problem of deception"of the generation.

3) The antenna is a transmitter and receiver device for transmitting data between the tag and the reader. In practical applications, in addition to the system power, the shape and relative position of the antenna will also affect the transmission and reception of data, and professionals are required to design and install the antenna of the system.
