RFID handheld terminal working principle and applicable fields
RFID handheld terminal, also called industrial PDA, it is a combination of hardware with special function, with comfortable appearance and industrial design, which is used in kinds of mobile field. RFID handheld terminals could collect data with RFID technology.
RFID handheld terminals contain three frequency range, they are LF, HF and UHF. LF handheld terminals collect data with short distance of RFID electronic label, such as timecard and canteen meal card. HF handheld terminals collect information with several centimeters of RFID electronic label, such as credit card and identification card. UHF handheld terminals could scan information with meters distance of RFID electronic label, most used in warehouse and fixed assets management.
RFID handheld terminals launch the electromagnetic wave in special area, and the region size depends on the size of antenna and working frequency. RFID labels are inserted LC series-resonant circuit, with the same frequency to handheld terminals. LC series-resonant circuit of RFID label will be resonated and make electric charge in capacitor, when the label passes the region area with the affects of electromagnetic wave. The other side of capacitor, electronic pump move the electric charge into another capacitor. If the amount of electric charge reach to 2V, the capacitor will be the battery of other electric pumps, and launch the data of label to handheld terminals. RFID handheld terminals get the data of label, they will error checking and decide the availability of the data. At last, handheld terminals send the data to internet by wifi or RS232、RS422、RS485.
RFID handheld terminals could be applicated to kinds industrial fields.
Firstly, traceability system. Food and medicine company required to build the quality safety electronic supervision system. With the usage of RFID, Auto-ID and sensor, the company could build the quality traceability service system, supply the service of quality and safety warranty.
Secondly, manufacturer. Manufacturers are involved in producing, purchasing, warehousing and transportation, they need to build the management and information service system with the usage of RFID handheld terminals. With the integration of the third logistics part, manufacturers could collect data by RFID handheld terminals, and trace the status of products, to improve the productivity.
Thirdly, warehousing. Workers of warehousing management could collect the data by RFID handheld terminals, and send the information to internet system. The usage of RFID handheld terminals could reduce the mistake of data, ensure the accuracy and timeliness, improve the productiveness of warehousing.
