Abstract
The utility model discloses a non-contact scanning radio-frequency module which is composed of the following components: a master control MCU, a UART communication interface, a radio frequency module, a radio frequency circuit and a power controller. The master control MCU is connected with the radio frequency module and the UART communication interface. The radio frequency module is connected with the power controller and the radio frequency circuit. The non-contact scanning radio-frequency module further has the following advantages: advanced designing mode, high product sensitivity, high power control accuracy within 0.5Db, and high scattering capability.
Description
Technical field
The utility model relates to the radio frequency identification equipment field, especially the radio-frequency module of RFID microwave read write line.
Background technology
RFID compares traditional recognition system to have and contains much information, and by communication rewritable data, confidentiality is fabulous, and adaptive capacity to environment is strong, longer service life.Along with development of technology, the RFID application enlarges day by day, has now related to the various aspects of daily life, and will become the basic technology that following information society is built.Second generation I.D., public transport etc. have all extensively adopted this technology at present, and supermarket such as Wal-Mart adopt electronic tag management commodity.Existing REID also is in the stage of a fast development in China, prospect is very wide, believe that the same each corner of coming into our daily life with other technology of REID makes our life more convenient along with technology is more and more ripe.
Summary of the invention
In order to realize simplified structure, improve stability, increase and read distance, the utility model proposes a kind of radio-frequency module of RFID microwave read write line.
The technical scheme that its technical matters that solves the utility model adopts is that this module is made up of main control MCU, UART communication interface, radio-frequency module, radio circuit, power controller, main control MCU is connected with radio-frequency module, UART communication interface, and radio-frequency module is connected with power controller, radio circuit.
Above-mentioned UART communication interface is RS232/RS485, TCP/IP.
The service band of above-mentioned module is 2.45GHz ISM wave band, and scattering power is strong.
The beneficial effects of the utility model are design advanced persons, and product is highly sensitive, and power control accurately can be controlled in 0.5Db, and scattering power is strong.
Description of drawings
Fig. 1 theory diagram of the present utility model;
1. main control MCU among the figure, 2. UART communication interface, 3. radio-frequency module, 4. radio circuit, 5. power controller.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
