Specific implementation mode

A kind of data interactive method of this specification embodiment offer, device and equipment.

In order to make those skilled in the art more fully understand the technical solution in this specification, below in conjunction with this explanation Attached drawing in book embodiment is clearly and completely described the technical solution in this specification embodiment, it is clear that described Embodiment be only this specification a part of the embodiment, instead of all the embodiments.The embodiment of base in this manual, The every other embodiment that those of ordinary skill in the art are obtained without creative efforts, should all belong to The range of this specification protection.

Embodiment one

As shown in Figure 1, this specification embodiment provides a kind of data interactive method, the executive agent of this method can be eventually End equipment, wherein the terminal device can such as personal computer equipment, can also such as mobile phone, tablet computer mobile terminal Equipment, the terminal device can be the terminal device that user uses.This method can be used for establishing terminal device and target terminal Between wireless connection, and when terminal device is close to target terminal, the wireless connection based on foundation carries out data interaction etc. In reason.This method can specifically include following steps：

In step s 102, the distance between target terminal is obtained.

Wherein, target terminal can be the terminal for needing to carry out data interaction with the terminal device of user, be handed over by data Scheduled processing or operation mutually may be implemented, for example, as shown in Fig. 2, target terminal can be the lock in subway or bus stop Machine, alternatively, can also be the POS on mass transportation facilities, alternatively, can also be building, library, enterprise campus or small Channel management equipment or traction equipment etc. in the access control systems such as area or ticketing system.

In force, currently, the scene of data interaction is very more, especially in current mobile payment field, graphic code (such as bar code or Quick Response Code) scanning, the anti-scheme of sweeping occupy most of scene, but the experience effect of above-mentioned scene depends on The camera quality of terminal device.In addition, under above-mentioned scene, a scanned side can not know the position being presently in.Example Such as, barcode scanning equipment (i.e. target terminal) cost on mass transportation facilities is not high, if the camera of the terminal device of user Recognition effect is bad, then is frequently necessary to the direction that user adjusts terminal device repeatedly, so that target terminal can correctly identify end The graphic code that end equipment is shown.In another example when taking subway, user needs the Quick Response Code by being shown in terminal device to ride, The Quick Response Code that can then show terminal device is placed on the two-dimensional code scanning window of gate (i.e. target terminal) offer, so that mesh Mark terminal opens channel, and user, which can enter in subway station, to ride.If user rides at the stations A, stands in B and scan two dimension Code it is outbound, then due to take subway when, the wireless signal of terminal device is generally poor, in this way, terminal device is likely to always In off-line state, in addition, target terminal is not real-time online, in this way, which subway can know is currently The gate stood scans the Quick Response Code of the terminal device of the user, to cannot achieve fare calculation.

In addition, further including the data interaction scene of other manner, such as carried out by the function of the NFC module of terminal device close Distance touching payment, since NFC (Near Field Communication, close range wireless communication) module is that near-field communication is special With component, therefore, the user experience that data interaction is carried out by NFC module is relatively stablized.But the terminal for having NFC function is set Standby quantity is simultaneously few, and the popularity rate of NFC is not high in terminal device, currently, only about 30% terminal device has NFC Module, and the permission of the not yet open NFC module of some terminal device, in addition, carrying out data interaction by NFC module There is also one-way communications, and the problem of can not write back.

In addition, in practical applications, further including the data interaction scene of other manner, such as passing through the bluetooth mould of terminal device The function of block carries out the data interaction of short distance, and still, distance of the bluetooth module between detecting distinct device and foundation are wireless There are problem in the speed of connection, that is, the range accuracy detected is relatively low, and it is slower to be wirelessly connected speed.

In practical applications, can according to signal strength (Received Signal Strength Indication, RSSI) judge the distance between the terminal device of target terminal and user, RSSI intensity is bigger illustrates target terminal and user The distance between terminal device it is closer, when RSSI intensity is more than preset intensity threshold, illustrates target terminal and use The distance between the terminal device at family is close enough, at this point, beginning setting up between target terminal and the terminal device of user Bluetooth connection simultaneously transmits the data for needing interaction.But the numerical value of RSSI intensity obtained above and inaccurate, in practical application In, user is likely located at the position of distance objective terminal 20cm, and the RSSI intensity at the position is whole more than target is close to instead RSSI intensity at the position at end.In another example taking mass transportation facilities, when close to swiping card equipment, for the 2 of front and back queuing A user can not judge that the bluetooth signal intensity of the terminal device of which user is stronger, if there are one user is complete in 2 users It at swiping the card, then can not judge which user completes the above-mentioned data exchange process swiped the card, or even can cause and mistake Terminal device has carried out data interaction, therefore, not can determine that RSSI intensity is just centainly sentenced more than preset intensity threshold User is determined close to target terminal.Moreover, the bluetooth of terminal device and the bluetooth of swiping card equipment establish connection and are also required to certain time, To reduce data interaction efficiency.

In addition, can also include the data interactive mode that bluetooth is combined with magnetic field, specifically, mesh in practical applications Bluetooth holotype can be in integrated electromagnets and bluetooth module, the bluetooth module of the terminal device of user by marking terminal, and target is whole End uses bluetooth subordinate mode, and broadcasts Bluetooth signal outward, meanwhile, the electromagnetic module in target terminal generates the progress of its field strength Periodically variable magnetic field.When user opens a terminal the related application of equipment, the magnetometer of terminal device does not stop to detect External magnetic field changes, and until having detected periodically variable magnetic field, then illustrates user close to target terminal, at this point, terminal Equipment begins setting up bluetooth connection with target terminal, and then, the bluetooth connection based on foundation carries out data interaction.But pass through During aforesaid way carries out data interaction, the bluetooth of terminal device and the bluetooth of target terminal are established connection and are also required to centainly Time, to reduce data interaction efficiency.

In addition, can also include the data interactive mode that Quick Response Code is combined with bluetooth in practical applications, specifically, The terminal device two-dimensional code display of user, wherein the Bluetooth information containing present terminal equipment, the Quick Response Code quilt in terminal device After gate (i.e. target terminal) scanning, gate obtains the Bluetooth address of terminal device from Quick Response Code, is set with terminal to establish Bluetooth connection between standby, then, the bluetooth connection based on foundation carry out data interaction.Likewise, carrying out through the above way During data interaction, the bluetooth of terminal device and the bluetooth of target terminal establish connection and are also required to certain time, to meeting Reduce data interaction efficiency.

In order to solve the problems, such as exist during carrying out data interaction above by aforesaid way, this specification embodiment A kind of scheme that data interaction is more efficient is provided, the following contents is can specifically include：

As shown in Fig. 2, wireless communication module (i.e. bluetooth module), the wireless communication module can be provided in target terminal It can be used for broadcasting or emit wireless signal, and transmission data etc..According to the difference of the wireless signal of broadcast or transmitting, channel radio Interrogating module can be different, for example, wireless communication module can be bluetooth module, infrared-ray communication module, Wi-Fi module or UWB (Ultra-Wideband, ultra wide band) module etc., this specification embodiment does not limit this.In order to better illustrate this programme Specific implementation process, and the communication module in view of being generally configured in terminal device, with wireless communication module in the present embodiment For bluetooth module, the case where for other wireless communication modules, it is referred to following related contents and executes, it is no longer superfluous herein It states.In addition, the wireless communication module of target terminal could be provided as subordinate mode.

Wireless communication module (i.e. bluetooth module) can also be provided in terminal device, and the wireless communication module can be with It is set as holotype, at this point, the wireless communication module in terminal device may search for the wireless signal of surrounding, and and target terminal Establish connection etc..In addition, can be provided with apart from detection module, such as range sensor in terminal device.

When user needs to carry out data interaction with target terminal (when specifically needing the gate by subway station such as user, Or user need swipe the card take mass transportation facilities when etc.), target terminal can outward be emitted wirelessly by wireless communication module Signal, wherein with the propagation of wireless signal, the intensity of wireless signal can be more and more weaker.Meanwhile target terminal can also start Range sensor, the distance between the terminal device of detection and user.The terminal device of user can also open wireless telecommunications mould Block, and the wireless signal of surrounding is searched for, furthermore, it is also possible to start apart from the distance between detection module detection and target terminal Deng.

When user moves closer to target terminal, the terminal device of user can enter the wireless signal of target terminal transmitting Coverage area in, at this point, the wireless communication module of terminal device can search the wireless signal of target terminal transmitting, and can be with Determine that (wireless signal strength can be the intensity of preset wireless signal, preset nothing for the intensity of the wireless signal Line signal may include a variety of, specifically may be set according to actual conditions, specific such as Bluetooth signal, infrared signal or Wi-Fi Signal etc.).In addition, terminal device after searching the wireless signal of target terminal, can be examined at a distance from the target terminal It surveys module to be communicated, determines the distance between terminal device and target terminal.For example, moving closer to target terminal in user When, the terminal device of user can search the Bluetooth signal of target terminal transmitting, and terminal device can measure the bluetooth received The intensity of signal, and the distance between target terminal is determined by range sensor.

As shown in Fig. 2, by above-mentioned processing, the distance between target terminal can be obtained, it can be by the distance of acquisition It is compared with preset first distance threshold (may be set according to actual conditions, such as 1 meter or 5 meters specific), if The distance between terminal device and target terminal reach the first distance threshold, then show user close to target terminal.Meanwhile If by above-mentioned processing, determine that the wireless signal strength that the terminal device of user receives (can more than predetermined signal strength threshold value To be set according to actual conditions, different signal strength thresholds can be arranged, in this specification in different wireless communication modules In another embodiment, different wireless communication modules can also be arranged identical signal strength threshold, this specification is implemented Example does not limit this), then show user close to target terminal, it is contemplated that terminal device wirelessly connects with target terminal foundation It connects and needs the regular hour, therefore, can begin setting up user's when wireless signal strength is more than predetermined signal strength threshold value Wireless connection between terminal device and target terminal, meanwhile, the processing of following step S104 can also be performed in terminal device, i.e., Establishing the process being wirelessly connected can be performed simultaneously with the processing of following step S104, in another embodiment of this specification In, the process for establishing wireless connection can also be to be executed before the processing of following step S104, that is, set up wireless connection Later, the processing etc. of following step S104 is executed, this specification embodiment does not limit this.

In step S104, when above-mentioned distance reaches second distance threshold value, and have been established wireless between target terminal When connection, the wireless connection based on foundation carries out data interaction with target terminal, which is to reach the in above-mentioned distance It is begun setting up before two distance thresholds.

Wherein, second distance threshold value may be set according to actual conditions, such as 0.2 meter or 0.5 meter specific.Above-mentioned first away from Second distance threshold value can be more than from threshold value, for example, the first distance threshold can be 1 meter, second distance threshold value can be 0.2 meter Deng.Data interaction can be the data interaction under the data exchange process under several scenes, such as payment scene mentioned above, Or data interaction under authentication scene or the data interaction etc. between terminal device under data exchange scene.

In force, as shown in Fig. 2, when user continues close to target terminal, the terminal that range sensor detects is set It is standby smaller and smaller with the distance between target terminal, when the distance between terminal device and target terminal reach second distance threshold value When, at this point, the wireless connection established between terminal device and target terminal should have been completed, then, terminal device can be with base Data interaction is carried out with target terminal in the wireless connection of foundation, for example, terminal device sends user's to the gate of subway station Account information after gate verifies account information, can record website or the outbound website by bus of user, and can open gate and permit Family allowable passes through, and can subsequently carry out the processing such as account settlement.
