Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
In the invention, the NFC is developed by combining a wireless interconnection technology on the basis of a non-contact Radio Frequency Identification (RFID) technology, and provides a very safe and rapid communication mode for various electronic products which are more and more popular in daily life. The "near field" in the NFC chinese name refers to radio waves in the vicinity of an electromagnetic field. Since radio waves are actually electromagnetic waves, it follows maxwell's equations, and electric and magnetic fields alternately perform energy conversion all the time when propagating from a transmitting antenna to a receiving antenna and enhance each other when performing the conversion, for example, radio signals used by our mobile phone propagate by using this principle, which is called far-field communication. Within 10 wavelengths of electromagnetic waves, the electric field and the magnetic field are independent from each other, the electric field has little meaning, but the magnetic field can be used for short-distance communication, which is called near field communication.
Example one
In order to solve the technical problems in the prior art, an embodiment of the present invention provides a data interaction apparatus.
Fig. 1 is a schematic structural diagram of an embodiment of a data interaction device of the present invention, and as shown in fig. 1, the data interaction device of this embodiment may include an interaction module 10, a control module 11, and a positioning module 12. Wherein the positioning module 12 is disposed on the interactive module 10 and is located at one side of the interactive area of the interactive module 10, so that a positioning detection area can be formed at one side of the interactive area of the interactive module 10. The control module 11 is electrically connected with the positioning module 12. The interactive module 10 may comprise a plurality of interactive units, each interactive unit being adapted to interact data with the interactive object within an interactive area. The interactive object may include an NFC interactive object such as an NFC card or tag.
When the NFC interactive object needs to perform data interaction with the interactive module 10, the positioning module 12 can detect that the NFC interactive object enters a positioning detection area, generate a positioning feedback signal of the NFC interactive object, send the positioning feedback signal of the NFC interactive object to the control module 11, after receiving the positioning feedback signal of the NFC interactive object, the control module 11 can analyze, calculate, and the like the positioning feedback signal of the NFC interactive object to obtain positioning information of the NFC interactive object, then, according to the positioning information of the NFC interactive object, determine a target interactive unit corresponding to the positioning information, and control the target interactive unit to enter an interactive state, so that the target interactive unit performs data interaction with the NFC interactive object in a corresponding interaction area. Therefore, no matter how many NFC interactive objects exist in the interactive area of the interactive module, the data interaction with each NFC interactive object can be realized quickly, and the omission of the NFC interactive objects is prevented.
In some embodiments, the positioning module 12 includes a plurality of infrared transmitters 121 and infrared receivers 122 disposed in one-to-one correspondence with each infrared transmitter 121; the infrared transmitter 121 is configured to transmit an infrared signal to the infrared receiver 122; the infrared receiver 122 is configured to receive an infrared signal emitted by the corresponding infrared emitter 121, generate a positioning feedback signal of the NFC interactive object when the NFC interactive object is located in the positioning detection area, and send the positioning feedback signal of the NFC interactive object to the control module 11.
Specifically, fig. 2 is a schematic diagram of an appearance structure of the data interaction device of the present invention, as shown in fig. 2, the appearance of the data interaction device may be a rectangular parallelepiped, fig. 2 may be a top view of the data interaction device, and the infrared emitters 121 may be disposed on two adjacent sides around the interaction module 10 of the data interaction device, and the infrared receivers 122 are disposed on the other two sides, respectively. The directions of emission of the infrared emitters 121 arranged on two adjacent sides are perpendicular to each other. Like this, the top of interactive module 10 can form an infrared ray net, and when the mutual object of NFC was close to the data module and carries out data interaction, then can shelter from the infrared ray in the infrared ray net, and infrared receiver 122 corresponding with sheltering from the region then generates the location feedback signal of the mutual object of NFC to send the location feedback signal of the mutual object of NFC for control module 11. The NFC interactive object may specifically be an NFC card.
In some embodiments, the control module monitors the state of each infrared receiver 122, when the infrared receiver 122 receives an infrared signal, it indicates that the signal of the infrared receiver 122 is not blocked, and when the infrared receiver 122 does not receive the infrared signal, it indicates that the signal of the infrared receiver 122 is blocked, and then the control module determines that an NFC interactive object exists in the receiving direction corresponding to the infrared receiver 122. Through signals in two mutually perpendicular directions, the position of the NFC interactive object can be accurately positioned, and therefore positioning information is obtained.
It should be noted that the present embodiment is not limited to the infrared positioning technology, and other positioning technologies may also be used, which are not illustrated herein.
In some embodiments, as shown in fig. 1, the interactive module 10 includes an analog switching device 102 and a first data interaction device 103 as an example; the technical scheme of the present invention is described by taking the example that each interaction unit includes one first antenna 101, so that one first data interaction device 103 can drive a plurality of first antennas 101, and one first data interaction device 103 does not need to be configured for each first antenna 101, thereby reducing the cost. The data interaction interface of the analog switch device 102 and the data interaction interface of the control module 11 are respectively electrically connected with the first data interaction device 103; each switch port of the analog switch device 102 is electrically connected with one first antenna 101 correspondingly; the switch switching input interface of the analog switching device 102 is electrically connected to the switch switching output interface of the control module 11.
Specifically, under the control of the control module 11, the switch switching input interface of the analog switch device 102 is communicated with the switch port of the first antenna 101 corresponding to the target interaction unit, so that the first data interaction device 103 is communicated with the first antenna 101 corresponding to the target interaction unit, and thus, the first data interaction device 103 can drive the first antenna 101 corresponding to the target interaction unit to enter an interaction state under the control of the control module 11, and thus, is not affected by the states of other first antennas 101 any more, and does not need to wait for polling to turn on the first antenna 101 corresponding to the target interaction unit, so that data interaction can be performed with the NFC interaction object quickly.
Fig. 3 is a schematic circuit diagram of the first data interaction device 103 in fig. 1, wherein the first data interaction device 103 may include a driving chip (not shown), an electromagnetic compatibility filter 1031, a matcher 1032, a voltage divider 1033, and a damping resistor 1034. The electromagnetic compatibility filter 1031 is electrically connected with the driver chip, the matcher 1032 is electrically connected with the electromagnetic compatibility filter 1031, the voltage divider 1033 is electrically connected with the matcher 1032, the driver chip and a data interaction interface of the analog switch device 102, and the damping resistor 1034 is electrically connected with the matcher 1032. Wherein the driving chip may include an NFC chip.
In some embodiments, the driver chip is configured to send a driving signal to a target antenna corresponding to the target interaction unit, so that the target antenna corresponding to the target interaction unit enters an interaction state, and thus, data interaction may be performed with the NFC interaction object, for example, related information stored in the NFC interaction object is read.
In some embodiments, the emc filter 1031 may adopt a single-stage low-pass filter structure, and is composed of a series inductor and a parallel capacitor, and the purpose of the emc filter 1031 is to filter a target harmonic in the driving signal to obtain a filtered driving signal.
In some embodiments, the matcher 1032 may be configured by a series capacitor and a parallel capacitor, and the purpose of the matcher 1032 is to match the filtered driving signal to obtain a desired impedance value of the target antenna.
In some embodiments, since the voltage on the antenna may be high, a voltage divider 1033 is needed in the receiving path at the antenna end to limit the signal strength returning to the driving chip for control, the voltage divider 1033 is connected to the antenna through the analog switch device 102, and the voltage divider 1033 may be composed of two capacitors.
In some embodiments, damping resistor 1034 is used to control the ratio of the antenna's inductive reactance to its equivalent loss resistance (Q value). For example, the Q value is lowered to avoid excessive high frequency resonance/gain.
In some embodiments, the analog switch device 102 may be selected according to actual requirements, for example, when the number of antennas is small, the analog switch device 102 may include only one multi-channel analog switch. When the number of the antennas is less, at least 2 multi-channel analog switches can be adopted for reducing the cost, and the multi-channel analog switches are connected in a cascading mode.
Specifically, the technical solution of the present invention is explained by taking an example that the analog switch device 102 includes 2 multi-channel analog switches. Fig. 4 is a schematic circuit diagram of a first-stage analog switching device of the analog switching device 102 of fig. 1, and fig. 5 is a schematic circuit diagram of a second-stage analog switching device of the analog switching device 102 of fig. 1. The first-stage analog switch device has 6 channels, the second-stage analog switch device has 12 channels, and after the two analog switch devices 102 are cascaded, the first-stage analog switch device can have 72 channels.
As shown IN FIGS. 4 and 5, the signals (named RFC-IN IN the figure) sent by the driver chip are firstly divided into 6 parts (named RFC-OUT 1-6 respectively) IN the 6-channel analog switch, and each channel is divided into 72 channels by the 2-stage 12-channel switch. The 72 channels are controlled and selected by the switch control signal. The switch control signals are composed of 3 (SP 6-V1-V3 in the figure) of 1-level analog switch control signals and 4 (SP 12-V1-V4 in the figure) of 2-level analog switch control signals, the switch of each channel is controlled, and the aim of only opening one antenna at the same time is achieved through the switch control signals.
It should be noted that other pin numbers (such as LS, RF2, GND1, etc.) in fig. 4 and 5 may refer to the model of the selected analog switching device 102 or, they are not described one by one here.
In the data interaction device of this embodiment, the positioning module 12 is disposed at one side of the interaction area of the interaction module 10 to form a positioning detection area at one side of the interaction area, when the interaction object is located in the positioning detection area, the positioning module 12 generates a positioning feedback signal of the interaction object, the control module 11 determines the positioning information of the interaction object according to the positioning feedback signal, and further determines the target interaction unit corresponding to the positioning information of the interaction object according to the positioning information of the interaction object, and then controls the target interaction unit to enter the interaction state, so that the target interaction unit performs data interaction with the interaction object in the corresponding interaction area, thereby avoiding the phenomenon that the target interaction unit cannot enter the interaction state due to the influence of other interaction units, and only the target interaction unit is in the working state, so that the overall energy consumption is low, therefore, high-efficiency interaction with the NCF interaction object is realized under the condition of low power consumption.

When the NFC interacting object needs to perform data interaction with the interacting module 10, the positioning module 12 can detect that the NFC interacting object enters a positioning detection area, and generates a positioning feedback signal of the NFC interactive object, and sends the positioning feedback signal of the NFC interactive object to the control module 11, after receiving the positioning feedback signal of the NFC interactive object, the control module 11, the positioning feedback signal of the NFC interactive object can be analyzed, calculated and the like to obtain the positioning information of the NFC interactive object, then, according to the positioning information of the NFC interaction object, a target interaction unit corresponding to the positioning information can be determined, and controls the second data interaction device 105 corresponding to the target interaction unit to drive the second antenna 104 corresponding to the target interaction unit to enter an interaction state, so that the second antenna 104 corresponding to the target interaction unit performs data interaction with the NFC interaction object in the corresponding interaction region. In this way, only the second data interaction device 105 and the second antenna 104 corresponding to the target interaction unit are in the working state, and the overall energy consumption is low, so that the high-efficiency interaction with the NCF interaction object is realized under the condition of low power consumption.
