The shape of the booth can be customized as required, and it can be spliced with the traditional booth flexibly and conveniently, thereby expanding the function of the traditional booth. the

The utility model is characterized in that it contains a booth 1, a physical exhibit 2, a radio frequency identification and a micro-control unit 3, wherein:

Stand 1, with a horizontal stand board,

Physical exhibits 2, more than one, with a radio frequency tag code on the bottom, and a physical exhibit number on the upper surface, placed on the upper surface of the booth 1,

The radio frequency identification and micro control unit 3 is located in the hollow booth board, and contains the radio frequency identification chip RFID Reader and the microprocessor chip ATMEGA8:

The RX end of the radio frequency identification chip RFID Reader is connected to the PD1 pin of the microprocessor chip ATMEGA8 through a resistor, and the TX end is connected to the PD0 pin of the microprocessor chip ATMEGA8 through another resistor. The chip RFID Reader reads the code of the radio frequency tag at the bottom of each physical exhibit 2 in real time, and inputs it into the microprocessor chip ATMEGA8,

The microprocessor chip ATMEGA8 is preset with a mapping table that identifies the number of the physical exhibit 3 and the corresponding radio frequency tag code, and a mapping table corresponding to the radio frequency tag code of the physical exhibit 3 and the image number of the physical exhibit, and puts the The image numbers of physical exhibits are output to an external computer. the

The microprocessor chip ATMEGA8 is connected in series with an expansion board chip FT232RL for connecting multiple radio frequency identification chips RFID Reader. the

Described radio frequency identification and the micro-control unit 3 are also provided with the serial number input key of the physical exhibit 2 that links to each other with each input end of described microprocessor chip ATMEGA8, and this serial number input key corresponds to described microprocessor chip ATMEGA8. Each digital key of the device chip ATMEGA8. the

The beneficial effect of the utility model is that the overall structure is simple, safe and easy to use, and strong in stability, and can be structurally spliced with various traditional booths, and is suitable for interactive display of various physical exhibits, that is, the traditional exhibition display of physical exhibits is retained It is customary and makes full use of the multimedia display method. When different physical exhibits are placed on the booth, the accurate identity information can be immediately transmitted to the computer connected to the booth for further processing. The real-time interaction is good and the scalability is strong, which greatly enriches the Exhibition display and education teaching mode of museums, science and technology museums and educational institutions. the

Detailed ways

The technical solution adopted by the utility model to solve the technical problem is: to package one or a group of RFID radio frequency identification card readers in the booth, and the surface of the booth for placing objects is made of wood or any non-metallic material, and the shape can be different. There are many kinds, which can be spliced with various traditional booths. The utility model is connected to a computer through a micro control unit (MCU) through a hardware interface (such as USB or RS232 serial port), and is powered by an independent power supply, or can be powered from an external computer through a USB interface. The booth also provides a variety of ultra-thin RFID passive tags and a set of tag identification programs running in the micro-control unit. You only need to attach the tag to the bottom of any physical exhibit 2, and the built-in micro-control unit can identify the placed on the booth. The identity information of the object on the surface, including the radio frequency tag code and the corresponding physical exhibit image number, the identity information can be transmitted to the external computer in real time through the hardware interface for further processing by the external computer, for example, according to different objects The identity information scrolls and plays different multimedia demonstration contents, which can also be selectively displayed by the audience through the radio frequency tag code input key of the physical exhibit 2 for the audience to choose and use on the microprocessor in the radio frequency identification and micro control unit 3 . the

In Figure 1, the booth embedded with RFID sensors is connected to the computer through a hardware interface, and the physical exhibits are any common physical exhibits or objects with passive tags. the
