Embodiment
For making the purpose, technical solutions and advantages of the present invention more outstanding, embodiment of the present invention are described in further detail below in conjunction with accompanying drawing.
Radio-frequency (RF) tag provided by the present invention as shown in Figure 1 and Figure 2, it includes label body 1, the housing of label body 1 is provided with relay indicating light 7 and charging indicator light 9, charging and data line interface 6, has mounting hole 2 simultaneously, switch jack 3; Be provided with power supply unit, controller unit, radio-frequency communication unit in the label body 1; Wherein controller unit comprises microprocessor, eeprom memory and Hall element; The radio-frequency communication unit comprises RFID chip, modulation circuit, demodulator circuit, amplifying circuit and antenna; Power supply unit links to each other with described radio-frequency communication unit respectively at described controller unit; With label body in the corresponding position 10 of Hall element dispose magnetic base plate 5;
For ease of power supply control, on-off plug 4 of configuration on each label body inserts on-off plug 4 in the switch jack 3 during use, to connect the power supply of label.Lose for fear of on-off plug 4, plug can be inserted in the idle jack 8 of label body when not using.Charging indicator light 9 is used for the indication of charged state, and relay indicating light 7 is used for the normal condition and the alarm condition of indicating label.Charging and data line interface 6 are used for radio-frequency (RF) tag is charged or the go forward side by side upgrading of rower label of link data line.
More particularly the inside of label body 1 constitutes as shown in Figure 2, and controller unit can select MCU processor, eeprom memory, LED indicator and Hall element (as AH3661) to constitute.The radio-frequency communication unit can select RFID chip, modulation circuit, demodulator circuit, amplifying circuit and PCB antenna to constitute (for raising the efficiency, the radio-frequency communication unit can adopt the integrated circuit (IC) chip that is made of RFID chip, modulation circuit, demodulator circuit, amplifying circuit); The radio-frequency communication unit links to each other with controller unit, mainly realize radiofrequency signal transmission, reception, modulate, separate and be in harmonious proportion processing such as amplification.Wherein controller unit can be gathered the data of Hall element, the data of Hall element just often, relay indicating light is shown in green; During the data exception of Hall element, relay indicating light is shown in red, and can send warning message by wireless radio frequency mode.Power supply unit can select rechargeable battery, on-off circuit and charging circuit to constitute, and power supply unit links to each other with the radio-frequency communication unit respectively at controller unit, for two unit provide required power supply.
The present invention provides a kind of simple and direct Hall element interface circuit (its as shown in Figure 3) at this, and the vdd pin of Hall element connects positive source, and the gnd pin connects power supply ground, and the out pin is received microprocessor and received positive source by pull-up resistor R1.For the clutter of filter out power, between positive source and ground, connect a capacitor C 0.When sensor surrounding magnetic field during greater than the detection threshold of sensor, the out pin is a low level signal; Otherwise when sensor surrounding magnetic field during less than the detection threshold of sensor, the out pin is a high level signal.By detection, know promptly whether working sensor is normal to the high-low level signal.
The interface circuit principle of the radio-frequency communication unit among the present invention can be controlled the power supply RFVDD of radio frequency part M1 as shown in Figure 4 by resistance R 10 and triode Q4.When control signal PWR_EN is low level, triode Q4 conducting, power vd D offers radio circuit M1 by Q4; When control signal PWR_EN was high level, triode Q4 ended, and power vd D disconnects.C7, L1 and C8 form filtering circuit, guarantee that power supply RFVDD's is stable.The CSN signal is used for the control of RFID chip operation, the transceiver mode of TRX_EN signal controlling RFID chip, and the IRQAM signal is used for the Data Receiving indication, and MOSI, MISO, SCK are data and clock line, finish the transmission of data jointly.
