Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise, and "a plurality" typically includes at least two.
The words "if", as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.
Under general conditions, electronic devices (such as smart phones, entrance guard card readers, attendance machines, bus card readers and the like) supporting NFC can recover NFC through a self fault-tolerant mechanism when the NFC function of the electronic devices is halted. However, in an actual operation process, there still exists a device supporting NFC, and the NFC function cannot be recovered after the NFC function crashes, and at this time, a user or an operator needs to restart the entire NFC electronic device, so that the entire NFC electronic device is restarted, and the NFC function is recovered.
For example, in a smart phone supporting NFC, generally, when the NFC of the smart phone is halted, an NFC application can restart the NFC according to a preset fault tolerance mechanism, so that the NFC application is recovered. However, the situation that the mobile phone cannot be recovered after the crash occurs, and at this time, the user needs to restart the smart phone to recover the NFC application of the smart phone, so that very poor experience is brought to the user.
To this end, the embodiment of the present application provides an electronic device supporting NFC.
As shown in fig. 1, the electronic device includes an NFC module and a device processor, wherein:
the NFC module includes: NFC chip, NFC antenna.
And an NFC reset pin is preset on the device processor and is connected with the NFC chip.
As shown in fig. 2, the electronic device according to the embodiment of the present application further includes an NFC service apparatus.
The NFC service device according to an embodiment of the present application is applied to an electronic device supporting NFC, and includes: the system comprises an upper service layer and a bottom service layer which is in interactive connection with the upper service layer.
Specifically, the NFC service device may be understood as a software architecture for providing NFC service in the electronic device according to the embodiment of the present application, where the software architecture is divided into three layers, where the first layer is an application layer, and may be understood as an APP application layer, including a system service application, an error handling and fault monitoring application, a sensor application, an executor application, a configuration and management application, an online upgrade application, and other peripheral applications; the second layer is a service layer, that is, the upper service layer in the embodiment of the present application, and includes a system function module, a memory function module, an input/output function module, a communication function module, and the like; the third layer is a driver layer, that is, the bottom service layer in the embodiment of the present application, and is a driver set including and supporting hardware; the application layer, the service layer and the driver layer are in interactive connection, and the application layer realizes the control of the driver layer on hardware by calling the service layer.
The bottom layer service layer is in communication connection with the NFC chip; preferably, the bottom layer service layer is specifically configured to be connected to the NFC chip by an IIC communication protocol.
The bottom layer service layer is used for receiving proximity information transmitted by an NFC chip protocol, the proximity information is generated when external equipment approaches the electronic equipment, and the external equipment supports NFC.
Specifically, as shown in fig. 3, when the external device supporting NFC approaches the electronic device according to the embodiment of the present application, that is, when the external device supporting NFC approaches the NFC antenna of the electronic device, the NFC chip generates proximity information and transmits the proximity information to the bottom service layer, that is, the driver layer, through the IIC communication protocol. The bottom service layer further sends proximity information to the upper service layer to inform the upper service layer that external equipment supporting NFC approaches.
And the upper service layer is used for driving the bottom service layer to acquire the equipment information of the external equipment from the NFC chip when receiving the proximity information transmitted by the bottom service layer. The device information may be card number, ID number, etc.
Specifically, for example, when a bus card (external device supporting NFC) approaches a bus card swiping machine (electronic device in this embodiment), an NFC chip sends proximity information to a bottom service layer, the bottom service layer transmits the proximity information to an upper service layer, and the upper service layer drives the bottom service layer to obtain device information such as a card number of the bus card and payment authorization control information from the NFC chip after receiving the proximity information.
The electronic device of the embodiment of the application supports the NFC function, and the NFC is a short-range communication technology and has certain distance limitation, namely a radio frequency distance. If the distance is too large, the electronic device of the embodiment of the application cannot read the external device signal. However, when the distance between the external device and the electronic device is just in the rf distance range, the electronic device may or may not read the external device signal, that is, in a critical state. At this moment, internal disorder is easily caused to the NFC chip in the electronic device according to the embodiment of the present application, and then the phenomenon of jamming is caused. At this time, the NFC function can be recovered only by restarting the entire electronic device, and the use experience is very poor.
For example, the electronic device of the embodiment of the application is an attendance machine, and the attendance machine is integrated with an NFC function, a camera shooting function, a fingerprint inputting function, a temperature measuring function, and the like. Taking the radio frequency distance of the attendance machine as 5CM as an example, the attendance card (external equipment supporting NFC) cannot be read when the distance from the attendance machine exceeds 5 CM. In the daily use scene of attendance machine, especially the rush hour of checking card on duty, the attendance machine frequently operates and uses, and in frequent operation process, the distance of attendance card and attendance machine frequently changes about the radio frequency distance, also is in above-mentioned critical state, causes inside NFC chip to take place inside disorder easily, and then leads to NFC function card to die, and this card dies the problem and can not resume through NFC's self fault-tolerant mechanism, need restart whole attendance machine and just can make NFC function resume. However, as described above, the attendance machine integrates other functional services besides the NFC function, and the entire attendance machine is restarted due to the dead NFC function, which brings great inconvenience to the user and causes poor user experience.
Therefore, the bottom layer service layer in the embodiment of the present application is further configured to detect a communication state between the NFC chip and the bottom layer service layer in real time.
The upper service layer is also used for pulling up the NFC reset pin when a communication abnormal event occurs so as to reset the NFC chip and restart the NFC service device. And the NFC reset pin is pulled up by the upper service layer, so that the NFC chip is subjected to hardware reset. By restarting the NFC service device, the NFC software in the electronic equipment is reset, and then the recovery of the NFC service of the electronic equipment is realized.
Specifically, the bottom service layer is configured to detect a communication state with the NFC chip in real time by determining whether the storage information of the NFC chip is received within a preset time range.
The communication abnormal event comprises the following steps: in a preset time range, the bottom layer service layer does not receive the storage information of the NFC chip; or within a preset time range, the storage information of the NFC chip received by the bottom layer service layer is discontinuous.
The stored information includes proximity information generated when an external device approaches the electronic device and/or device information of the external device, the external device supporting NFC.
And the bottom service layer is also used for forcibly returning successful communication state information to the upper service layer before the upper service layer restarts the NFC service device, wherein the successful communication state information is used for representing the successful communication between the bottom service layer and the NFC chip, so that the upper service layer can continue to operate.
The bottom service layer is further used for continuously carrying out communication connection with the NFC chip when the upper service layer restarts the NFC service device on the electronic equipment.
The embodiment of the application also provides a jam recovery method, which is applied to the electronic equipment of the invention,
the NFC service device is configured on the electronic equipment and comprises an upper service layer and a bottom service layer which is interactively connected with the upper service layer; the bottom layer service layer is in communication connection with the NFC chip;
the method comprises the following steps:
the bottom service layer detects the communication state between the NFC chip and the NFC chip in real time;
and if the communication abnormal event occurs, the upper service layer pulls up the NFC reset pin so as to reset the NFC chip and restart the NFC service device.
The communication state between the bottom service layer real-time detection and the NFC chip is specifically as follows:
and the bottom service layer judges whether the storage information of the NFC chip is received within a preset time range so as to detect the communication state between the NFC chip and the bottom service layer.
The communication abnormal event comprises the following steps: in a preset time range, the bottom layer service layer does not receive the storage information of the NFC chip; or within a preset time range, the storage information of the NFC chip received by the bottom layer service layer is discontinuous.
The stored information includes proximity information generated when an external device approaches the electronic device and/or device information of the external device, the external device supporting NFC.
Before the upper service layer restarts the NFC service device on the electronic device, the method further includes:
and the bottom service layer forcibly returns successful communication state information to the upper service layer, wherein the successful communication state information is used for representing that the bottom service layer is successfully communicated with the NFC chip, so that the upper service layer can continuously operate.
When the upper service layer restarts the NFC service device on the electronic device, the method further includes: and the bottom service layer is continuously in communication connection with the NFC chip.
