Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
Referring to fig. 1, a first flowchart of a file calling method according to the disclosure is shown, where the method is applied to an electronic device including an NFC chip. As shown in fig. 1, the file calling method may include:
step 101: when the NFC matching device is identified, detecting whether a specified configuration file exists in a first saving path; if yes, go to step 102; if not, go to step 103;
the NFC equipment is identified, and when a user approaches a bus or subway card swiping machine, an NFC signal on the card swiping gate can be identified by the NFC chip in an induction mode. Typically, the identification distance of NFC signals is less than 20 centimeters.
The specified configuration file can be an NFC configuration file which is acquired from a cloud and corresponds to a card-opening city of a built-in bus card according to the card-opening city of the built-in bus card in the mobile phone by an electronic wallet APP in the mobile phone. The NFC configuration file is correspondingly set according to the specification standard of the card swiping gate in each traffic line in the card opening city. When the electronic wallet APP is applied to a public transport card opened by a user, the corresponding configuration file can be immediately obtained from the cloud, and the configuration file is stored to a fixed path of a mobile phone system, namely, a first storage path to become a designated configuration file.
Step 102: calling the specified configuration file;
and when the user swipes the card in the card-opening city by NFC, the appointed configuration file in the first saving path can be called. Because the specified configuration file is set according to the specification standard of the card swiping gate in each traffic line in the card opening city, when the specified configuration file is called and loaded to the NFC system, the software parameters corresponding to the NFC chip in the mobile phone and the NFC chip in the card swiping gate can be successfully matched, and the mobile phone card swiping or recharging is ensured to be successful.
Step 103: and calling a default configuration file under the second saving path.
In some cases, the wallet APP may not download the specified configuration file from the cloud in time, or download and store the configuration file to the first storage path, and delete the configuration file for other reasons, and at this time, the first storage path is empty, and the system may call the default configuration file in the second storage path to ensure that the NFC chip can be normally used. The default configuration file is an NFC default configuration file when the mobile phone leaves a factory. The NFC default configuration file is not applicable to all model parameters of the card gate.
In this embodiment, when the NFC matching device is identified, the file calling method first detects whether a specified configuration file exists in the first saving path, and if so, calls the specified configuration file, and if not, calls the default configuration file in the second saving path. The method has the advantages that the binding relationship between the NFC configuration file and the electronic equipment system is eliminated, and under the condition that the NFC configuration file specified by the current city exists in the electronic equipment, the specified NFC configuration file can be called according to the requirements of upper-layer application when the electronic equipment performs an NFC action, so that the user can successfully perform NFC card swiping/recharging, and the use experience of the user is improved.
On the basis of the foregoing embodiment disclosed in the present invention, fig. 2 is a second flowchart of a file calling method disclosed in the embodiment of the present invention, and referring to fig. 2, the file calling method may include:
step 201: receiving a designated configuration file which is sent by a target application, downloaded from a cloud end and matched with the position information and the equipment information of the electronic equipment, and storing the configuration file in a first storage path;
in this embodiment, the mobile phone system may first receive and store the designated configuration file sent by the target application. The target application may be, but is not limited to, an electronic wallet APP application. The file calling method of the embodiment is suitable for the first time that a user opens a city traffic card or other scenes needing to download and store the specified configuration file. After a user opens a traffic card of a current city, the wallet APP sends card opening information containing a city name and mobile phone equipment information to the cloud end, requests to download an NFC configuration file corresponding to the city name and the equipment model, and sends the NFC configuration file to the mobile phone system after the NFC configuration file is downloaded successfully, so that the corresponding NFC configuration file is stored as an appointed configuration file under the first storage path by the mobile phone system. The mobile phone device information may include model parameter information of the NFC chip.
Step 202: when the NFC matching device is identified, detecting whether a specified configuration file exists in a first saving path; if yes, go to step 203: if not, go to step 204:
step 203: calling the specified configuration file;
step 204: and calling a default configuration file under the second saving path.
In this embodiment, under the condition that the user opens the urban traffic card for the first time or needs to download and store the specified configuration file, the target application downloads the specified configuration file corresponding to the urban information and the electronic device information from the cloud and sends the configuration file to the mobile phone system for storage, so that when the user subsequently swipes/recharges at the gate, the electronic device system can call the specified configuration file and load the configuration file to the NFC system, and the successful swiping/recharging is ensured.
It should be noted that, in practical applications, a user may arrive from one city to another city due to traveling. The electronic wallet APP can determine this by GPS information. In this case, the wallet APP may download NFC configuration information corresponding to the new city from the cloud, and send a prompt to the mobile phone system, so that the mobile phone system deletes the original specified configuration file stored in the first storage path. Specifically, on the basis of the file calling method disclosed in the above embodiment, the file calling method may further include the following steps: when the position information of the electronic equipment is switched from a first city to a second city, deleting the specified configuration file under the first saving path; and receiving a designated configuration file which is sent by a target application, downloaded from a cloud and matched with the second city, and storing the configuration file in the first saving path. The above steps may be performed at any time after step 201.
In another embodiment, the NFC configuration file stored in the cloud is also updated. In specific application, the wallet APP application may periodically or periodically detect whether the NFC configuration file in the cloud is updated, and if so, the latest NFC configuration file needs to be downloaded and transmitted to the mobile phone system for storage. Specifically, on the basis of the file calling method disclosed in the above embodiment, the file calling method may further include the following steps: when the target application detects that the designated configuration file matched with the position information of the electronic equipment is updated, deleting the designated configuration file under the first saving path; and receiving and storing the updated designated configuration file sent by the target application to the first saving path. The above steps may be performed at any time after step 201.
Further, fig. 3 discloses a third flowchart of a file invoking method, which is applied to an electronic device including an NFC chip. As shown in fig. 3, the file calling method may include:
step 301: receiving a designated configuration file which is sent by a target application, downloaded from a cloud end and matched with the position information and the equipment information of the electronic equipment, and storing the configuration file in a first storage path;
step 302: when the NFC matching device is identified, detecting whether a specified configuration file exists in a first saving path; if yes, go to step 303; if not, go to step 304:
step 303: calling the specified configuration file; step 305 is entered;
step 304: calling a default configuration file under a second saving path; step 305 is entered;
step 305: judging whether the system is upgrading the NFC firmware; if yes, go to step 306;
step 306: deleting the specified configuration file stored under the first saving path.
And when the NFC firmware is upgraded, the software parameters of the NFC firmware are correspondingly changed, and at the moment, the corresponding parameters in the NFC configuration file also need to be adaptively adjusted, so that the NFC chip can be successfully swiped when a subsequent user performs an NFC action.
And when the NFC firmware is upgraded, the specified configuration file stored in the first saving path is not updated, and at the moment, the specified configuration file in the first saving path needs to be deleted, so that a card swiping error caused by the fact that the specified configuration file is not updated when a user performs an NFC action after the NFC firmware is upgraded is avoided.
When the determination result in step 305 is negative, no operation is performed. The execution of step 305 and step 306 is not necessarily after step 303 or step 304, which may be implemented at any time after step 301.
In this embodiment, the file calling method may automatically delete the specified configuration file stored in the first saving path when the NFC firmware is upgraded, so as to avoid an error in NFC card swiping caused by loading an original specified configuration file on an NFC chip due to the NFC firmware upgrade.
The method is described in detail in the embodiments disclosed above, and the method of the present invention can be implemented by various types of apparatuses, so that the present invention also discloses an apparatus, and the following detailed description will be given of specific embodiments.

Typically, the identification distance of NFC signals is less than 20 centimeters.
A file detection module 402, configured to detect whether a specified configuration file exists in a first storage path when the NFC matching device is identified by the device identification module;
the specified configuration file can be an NFC configuration file which is acquired from a cloud and corresponds to a card-opening city of a built-in bus card according to the card-opening city of the built-in bus card in the mobile phone by an electronic wallet APP in the mobile phone. The NFC configuration file is correspondingly set according to the specification standard of the card swiping gate in each traffic line in the card opening city.

Because the specified configuration file is set according to the specification standard of the card swiping gate in each traffic line in the card opening city, when the specified configuration file is called and loaded to the NFC system, the software parameters corresponding to the NFC chip in the mobile phone and the NFC chip in the card swiping gate can be successfully matched, and the mobile phone card swiping or recharging is ensured to be successful.
