All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Correspondingly, the object can be commodities (such as bread and yoghourt) placed in the intelligent refrigerator, the object can be clothes, bedding and the like placed in the intelligent washing machine, and the object can also be bowls and dishes placed in the intelligent dishwasher. It should be understood that the corresponding objects are different according to the different intelligent devices.
It is understood that fig. 1 illustrates an example in which the intelligent device is an intelligent washing machine and the object is clothes. In the prior art, a radio frequency identification RFID tag (such as a rectangular gray color block on a piece of clothing) is arranged on a piece of clothing, and data of the piece of clothing, such as material and quality of the piece of clothing, is stored in the RFID tag. The intelligent washing machine is provided with an RFID reader-writer, and the RFID reader-writer can identify RFID tags on clothes and read clothes data stored in the RFID tags in the process that a user puts the clothes into the intelligent washing machine. The intelligent washing machine can select a washing mode (washing program, washing time, detergent and the like) suitable for the clothes according to the data of the clothes to carry out intelligent washing.
However, in the data acquisition mode in the prior art, an RFID reader/writer needs to be arranged on each intelligent washing machine, so that the cost of the intelligent washing machine is increased, and the washing machine executes RFID tag identification and data acquisition, so that the data processing capacity of the washing machine is increased.
In order to solve the above technical problem, the present application provides a data processing method. The following first describes a system architecture to which the data processing method is applied, with reference to fig. 2. Fig. 2 is a first schematic diagram of a system architecture to which the data acquisition method provided in the present application is applicable. As shown in fig. 2, the system architecture includes: intelligent device, base station and server. The following description will take an intelligent device as an example of an intelligent washing machine.
Wherein, the clothes are provided with radio frequency identification RFID labels. When the intelligent washing machine detects the RFID tag of the clothes, the intelligent washing machine can send an excitation signal to the RFID tag of the clothes, wherein the excitation signal is used for instructing the RFID tag to transmit a radio frequency signal, and the radio frequency signal comprises the data of the clothes. Correspondingly, the base station within the coverage range of the radio frequency signal can detect the radio frequency signal emitted by the RFID label.
Optionally, the base station within the coverage area of the radio frequency signal may determine the target base station by using an existing interaction manner, that is, the base station with the strongest detected radio frequency signal strength. Illustratively, base station a in fig. 2 is the target base station.
After the target base station acquires the radio frequency signal, the server corresponding to the intelligent washing machine can send the data of the clothes indicated in the radio frequency signal to the server corresponding to the intelligent washing machine, so that the server stores the data of the clothes. Further, the server is opened with an interface or access address, which is pre-agreed. The intelligent washing machine may acquire data of the laundry by accessing the server.
According to the data acquisition method, the intelligent device enables the RFID tag to send the data of the object stored in the intelligent device to the base station in a mode of exciting the RFID tag, so that the data of the object can be stored in the server corresponding to the intelligent device, the intelligent device can acquire the data of the object in the server, and the purpose of reducing the data processing amount of the intelligent device is achieved.
The following describes the data processing method provided by the present application from the perspective of interaction between the smart device, the RFID tag provided on the object, the target base station, and the server. Fig. 3 is an interaction flow diagram of the data acquisition method provided by the present application. As shown in fig. 3, the data acquiring method provided in this embodiment may include:
s301, the intelligent device sends an excitation signal to the radio frequency identification RFID tag of the target object, the excitation signal indicates the RFID tag of the target object to emit a radio frequency signal, and the radio frequency signal comprises data of the target object and the identification of the intelligent device.
Correspondingly, the RFID tag of the target object receives the excitation signal from the intelligent device.

Optionally, the smart device in this embodiment may be started after receiving the start instruction. The starting instruction can be triggered by a user selecting a starting button on the intelligent device or by the user operating a terminal device bound with the intelligent device. In this embodiment, the starting mode of the intelligent device is not limited.
The target object in this embodiment may be an object within a preset range of the smart device. For example, if the intelligent device is an intelligent washing machine, the target object is clothes put into the intelligent washing machine, that is, the clothes within 1 meter around the intelligent washing machine can be taken as the target object.
The smart device in this embodiment may send an excitation signal to the RFID tag of the target object. Wherein the excitation signal instructs the RFID tag of the target object to emit a radio frequency signal, i.e. the radio frequency signal may be emitted after the RFID tag of the target object receives the excitation signal.
The radio frequency signal emitted by the RFID tag of the target object can include the data of the target object and the identification of the intelligent device. The RFID tag of the target object stores data of the target object, the excitation signal can include an identification of the intelligent device, and after the RFID tag of the target object receives the excitation signal, a radio frequency signal can be generated according to the data of the target object stored in the RFID tag and the identification of the intelligent device.
Fig. 4 is a schematic diagram of a system architecture applicable to the data acquisition method provided by the present application. In one possible implementation, as shown in FIG. 4, a smart device is provided with a processor and a tag activation module. The intelligent device receives the starting instruction, namely the processor in the intelligent device receives the starting instruction. After the processor receives the starting instruction, a control instruction can be sent to the tag excitation module, and the control instruction is used for instructing the tag excitation module to transmit an excitation signal to the RFID tag of the object within the preset range. The RFID tag of the object within the preset range is the RFID tag of the target object in this embodiment.
The tag excitation module in this embodiment may generate an excitation signal and transmit the excitation signal to the RFID tag of the target object. It should be noted that, the manner of generating the excitation signal by the tag excitation module in the present embodiment may refer to the related description in the prior art.
S302, the RFID label of the target object transmits a radio frequency signal.
In this embodiment, the RFID tag of the target object may transmit a radio frequency signal after receiving the excitation signal from the smart device. The radio frequency signal includes data of the target object and an identifier of the smart device, and the identifier of the smart device may be information capable of uniquely identifying the smart device, such as a production serial number and a model number of the smart device.
Optionally, the excitation signal sent by the smart device to the RFID tag of the target object may carry an identifier of the smart device. After the RFID tag of the target object receives the excitation signal, a radio frequency signal may be generated according to the identification of the smart device, the data of the target object, and a preset rule.
S303, the target base station detects a radio frequency signal from the RFID tag of the target object.
When the RFID tag of the target object transmits a radio frequency signal, the base stations in the coverage area of the radio frequency signal can detect the radio frequency signal. In this embodiment, the base station that detects the radio frequency signal may determine the target base station through an interaction manner in the prior art, where the target base station is: the base station with the strongest signal strength of the radio frequency signals in the base stations capable of detecting the radio frequency signals.
As shown in fig. 4, the base stations in this embodiment are all disposed with tag receiving modules. The target base station detects the radio frequency signal from the RFID tag of the target object, that is, the tag receiving module receives the radio frequency signal from the RFID tag of the target object. The tag receiving module may parse the received radio frequency signal to obtain the data of the target object and the identification of the smart device.
It should be understood that the preset rule of the radio frequency signal generated by the RFID tag in this embodiment may be predetermined, and corresponds to a manner in which the tag receiving module analyzes the radio frequency signal.
And S304, the target base station sends the data of the target object and the identification of the intelligent equipment to a server corresponding to the intelligent equipment according to the identification of the intelligent equipment.
Correspondingly, the server receives the data of the target object from the target base station and the identification of the intelligent device.
The base station in this embodiment stores a correspondence between the identifier of the smart device and the identifier of the server, as shown in the following table one:
watch 1
Identification of intelligent device Server
1 a
2 b
3 c
It should be understood that the above table is only an example, and the target base station in this embodiment may also determine the identifier of the server corresponding to the identifier of the smart device in other manners. It is contemplated that the identification of the smart device stored in the target base station may be an identification of a smart device registered within a cell corresponding to the target base station.
In this embodiment, after the target base station parses and acquires the identifier of the smart device corresponding to the radio frequency signal and the data of the target object, the identifier of the server corresponding to the identifier of the smart device may be determined according to the identifier of the smart device, and then the data of the target object and the identifier of the smart device are sent to the server corresponding to the smart device.
S305, the server stores the data of the target object and the identification of the intelligent device.
After the server corresponding to the intelligent device receives the data of the target object and the identifier of the intelligent device sent by the target base station, the data of the target object and the identifier of the intelligent device can be stored. The following table two shows that the server stores the data of the target object and the identifier of the intelligent device in a list manner.

S306, the intelligent device sends a data access request to the server, wherein the data access request comprises the identification of the intelligent device.
After sending the excitation signal to the RFID tag of the target object, the smart device may access a server corresponding to the smart device to obtain data of the target object. The server is provided with an interface or an access address, the intelligent device can send a data access request to the server according to the open interface or the access address, and the data access request indicates the server to return data of a target object corresponding to the identifier of the intelligent device, so that the server can return the data of the target object to the intelligent device when receiving the data access request.
The data access request in this embodiment includes the identifier of the smart device, and correspondingly, because the data of the target object corresponding to the identifiers of different smart devices may be stored in the smart device, when the server receives the data access request from the smart device, the server may obtain the data of the corresponding target object according to the identifier of the smart device in the data access request, and further send the data of the target object to the smart device.
Optionally, as shown in fig. 4, a communication module (e.g., a 5G module) is disposed in the smart device, and correspondingly, the target base station is a base station (e.g., a 5G base station) corresponding to the communication module. The intelligent device can send a data access request to the target base station through the 5G module, so that the target base station can forward the data access request to a server corresponding to the intelligent device.
In one possible implementation, the start instruction of the smart device is sent by the terminal device bound to the smart device. Optionally, a start control may be displayed on the terminal device, and the user may trigger the terminal device to send a start instruction to the intelligent device by selecting the start control.
After the terminal device sends the start instruction to the intelligent device, the terminal device can also access the server according to an open interface or an access address of the server, that is, the terminal device can send a data access request to the server, so that the server returns the data of the target object to the terminal device, and a user can view the data of the target object on the terminal device.
It should be understood that the identifier of the smart device bound to the terminal device may be included in the data access request sent by the terminal device to the server, so that the server sends the data of the target object corresponding to the identifier of the smart device to the terminal device.
S307, when the server receives a data access request from the intelligent device, the server sends the data of the target object to the intelligent device.
Correspondingly, the intelligent device receives data of the target object from the server.
In this embodiment, when the server receives a data access request from the intelligent device, the server may obtain data of a corresponding target object according to the identifier of the intelligent device in the data access request, and further send the data of the target object to the intelligent device.
In addition, the server may further store a plurality of target objects corresponding to the identifier of the smart device, so that the server returns accurate data of the target object requested by the smart device.
In a possible implementation manner, the data access request in this embodiment may further include: the moment the smart device sends an excitation signal to the RFID tag of the target object. And when the target base station sends the data of the target object corresponding to the identification of the intelligent equipment to the server, the time when the target base station detects the radio frequency signal corresponding to the identification of the intelligent equipment and the data of the target object is also sent. Correspondingly, when the server stores the data of the target object, the identifier of the intelligent device, the data of the target object and the moment when the target base station detects the radio frequency signal can be correspondingly stored.
Illustratively, the third table exemplarily shows that the server stores the identification of the smart device and the data of the target object corresponding to two different times (the time when the target base station detects the radio frequency signal):
watch III
Figure BDA0002231247320000111
As shown in the third table, the server stores the identifier of the smart device corresponding to the time when the different target base stations detect the radio frequency signal, and the data of the target object corresponding to the identifier of the smart device.
In combination with the above, the data access request may further include: the moment the smart device sends an excitation signal to the RFID tag of the target object. For example, the intelligent device is an intelligent washing machine, and when the intelligent washing machine washes clothes each time, the moment when the intelligent device sends an excitation signal to the RFID tag of the target object is always earlier than the moment when the target base station detects a radio frequency signal. Accordingly, the data of the target object requested by the smart device in the present embodiment is the data of the target object corresponding to the identification of the smart device after the time when the smart device transmits the excitation signal to the RFID tag of the target object.
Correspondingly, the data access request instructs the server to return the data of the target object corresponding to the identification of the smart device after the moment that the smart device transmits the excitation signal to the RFID tag of the target object.
Illustratively, if the time when the intelligent washing machine sends the excitation signal to the RFID tag of the target object is 11 hours, 10 months, 10 days and 59 minutes in 2019, correspondingly, the server stores the data of the target object corresponding to the identification of the intelligent device, which is sent when the target base station detects the radio frequency signal at the time of 2019 months, 10 days, 12 hours and 00 minutes.
Correspondingly, when the server receives the data access request sent by the intelligent device, the data of the target object which is stored after 9, 10, 11, 59 minutes in 2019 and corresponds to the intelligent device can be sent to the intelligent device.
In this embodiment, the data access request carries a time when the smart device sends an excitation signal to the RFID tag of the target object, and a time when the target base station further sends a radio frequency signal detected by the target base station when sending the identifier of the smart device and the data of the target object to the server, so that the server can return accurate data of the target object when receiving the data access request from the smart device.
In a possible implementation manner, if the smart device does not receive the data of the target object from the server within a preset time period after sending the data access request to the server, the smart device may send the excitation signal to the RFID tag of the target object again, and correspondingly, the steps in S301 to S306 may be further performed until the smart device receives the data of the target object from the server.
