Problems solved by technology
When it is necessary to obtain user information, it is also necessary to insert the electronic information card into the jack, which is troublesome
In addition, the power supply part of the traditional exhibition information service system uses many components, the circuit structure is complicated, the hardware cost is high, and it is inconvenient to maintain
In addition, because the power supply part of the traditional exhibition information service system lacks corresponding circuit protection functions, such as the lack of signal interference prevention functions, the safety and reliability of the circuit are poor

The invention discloses a convention and exhibition information service system, comprising a convention and exhibition host, a card issuing terminal, an RFID tag, an exhibition information collector and an exhibition stand display; wherein the information of all convention and exhibition users is stored in the convention and exhibition host; the card issuing terminal is connected with the convention and exhibition host; the card issuing terminal is in wireless connection with the RFID tag, the exhibition information collector and the exhibition stand display are installed on each exhibition stand, the exhibition information collector comprises an RFID reader-writer, a single-chip microcomputer, a touch screen and a power supply module, a plurality of virtual function keys are arranged on the touch screen, and a two-dimensional code scanning area is arranged on the exhibition stand display. The power supply module comprises a voltage input end, a voltage output end, a first resistor, afirst diode, a second resistor, a first capacitor, a first triode, a second triode, a third triode, a second capacitor, a third capacitor and a second diode. The system is simple in circuit structureand lower in cost, is convenient to maintain and is higher in circuit safety and reliability.
Description
technical field [0001] The invention relates to the field of exhibition services, in particular to an exhibition information service system. Background technique [0002] Nowadays, many exhibitions are held every year all over the country. Manufacturers will display their products at the exhibitions, and customers from all over the country will also go to the exhibitions to find the products they need. Some existing exhibition information collection systems store the exhibition information of each booth through the electronic information card, read the exhibition information in the electronic information card through the exhibition information collector, and display the exhibition information through the booth display, which is convenient for people to watch and avoids the use of publicity If people find out which booth's exhibit information is what they need, they can scan the QR code on the booth display to obtain all the exhibit information of the booth, avoiding the use ...
