In order to more clearly describe the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can also be obtained from these drawings without creative efforts, and obtain other implementations.

In order to keep the drawings concise, the drawings only schematically show the parts related to the present invention, and they do not represent its actual structure as a product. In addition, in order to make the drawings concise and easy to understand, only one of the components having the same structure or function in some drawings is schematically drawn, or only one of them is marked. As used herein, "one" not only means "only one", but also "more than one".

In one embodiment of the present invention, as shown in Figure 1, an information reminder method includes:

Step S100 determines whether the current NFC device is a target NFC device according to the user's NFC card swiping information.

Specifically, the user's NFC card swiping information refers to the card swiping information obtained by the user's mobile terminal when the user successfully uses his mobile terminal to swipe the NFC device.

The user's mobile terminal is a mobile terminal with an NFC function, including a wearable device such as an NFC mobile phone, an NFC watch/band, and the like. Such mobile terminals can be used as NFC simulated cards, such as simulating access control cards, transportation cards, bank cards and other cards, so that users do not need to carry multiple cards with them.

NFC devices, compared to NFC analog cards, are used to exchange information with NFC analog cards to realize functions such as identity recognition and contactless payment, such as NFC card readers on buses, NFC card readers in community access control devices, etc. .

The target NFC device refers to the access control device of the target area with NFC function. The target area can be preset. For example, assuming that the target area is cell A, the corresponding target NFC device is the access control device of cell A. It can obtain the user identity information of the access control card or access control analog card, and judge whether the user has the right to pass according to the user identity information. And when the user has the right to pass, it will be released.

Every time the user performs a successful NFC card swiping operation using the mobile terminal, a card swiping message will be generated on the mobile terminal side. Optionally, the card swiping information includes the card swiping location and the type of the NFC analog card used. When the swiping position is located in the target area and the NFC analog card type used is an access control card, the current NFC device is the target NFC device.

For example, it is assumed that the target NFC device is an access control device of cell A. When the user uses the mobile terminal to simulate swiping the bus card to get on the bus, a piece of card swiping information is obtained; according to the card swiping information, it can be known that the transportation card is used, so the current NFC device is not the target NFC device. When the user goes home and swipes the card successfully before entering and exiting the access control device in cell A, another card swiping information is obtained; according to the card swiping information, it can be seen that the access control analog card is used, and the swiping position is located in cell A, so it can be confirmed that the current NFC device is the target NFC device.

In step S200, when the current NFC device is the target NFC device, corresponding reminder information is generated according to the user's travel direction, and the reminder information is sent to the associated terminal of the user.

Specifically, the user's associated terminal refers to other terminals bound to the user's mobile terminal. For example, the user is a child, and the mobile terminal used by the child's mother or father or his guardian is the child's associated terminal. Usually, the associated terminal is set on the child's mobile terminal, so that the guardian can know the safety situation of the child outside in real time.

The user's travel direction means that the user leaves the target area or enters the target area. The target NFC device is the access control device in the target area. Therefore, when the user swipes the card in front of the target NFC device, the corresponding reminder information can be accurately generated and sent to the user's associated terminal in time according to the direction of travel. The reminder information can also include the time when the event occurred. Compared with the traditional method of generating information reminders according to changes in user positioning information, this method can generate and send reminder information more accurately.

Optionally, obtain the location information recorded by the user before reaching the target NFC device; and determine the passing direction of the user according to the recorded location information and the location information of the target NFC device. When both the recorded location information and the location information of the target NFC device are located in the target area, it is determined that the user's passing direction is to leave the target area. When the recorded location information is not located in the target area, it is determined that the user's passing direction is entering the target area.

According to the positioning function of the mobile terminal, such as positioning means such as GPS or wireless base station, the position information recorded by the user before reaching the target NFC device can be obtained.

One implementation is to acquire and record the location information of the user at a specific time. For example, the specific time is set to 6:00 am and 1:00 pm, and the location information of the child at 6:00 am and 1:00 pm is obtained and recorded according to the positioning function of the mobile terminal. Specifically, the location information of two time points can be recorded separately, and the user's traffic direction can be judged by selecting the location information closest to the current time point and comparing it with the target NFC device; Update the location information. By limiting the update of the recorded location information at a specific time, the number of updates can be reduced, the computational load of the mobile terminal can be reduced, and it is beneficial to save power of the terminal.

Further optionally, when the user's mobile terminal detects the WIFI at the user's home, the recorded location information is the home address. This method is more accurate than traditional GPS or base station positioning.

Taking a child going to school as an example, the current location of the user is obtained at 6:00 in the morning. When the home WIFI signal is detected, it means that the child is at home, and the location information is recorded in the watch as the home address. The home address can be preset in the watch. The child leaves the house, comes to the gate of the community, and leaves the community by brushing the access control of the community. At this time, the watch obtains a piece of NFC card swiping information. According to the swiping position and the type of NFC analog card used, it can be known that the current NFC device is the target NFC device, that is, the access control device of the community.

According to the location information recorded in the watch and the location information of the target NFC device, it is determined that the child is leaving the cell, and accordingly, a reminder message for leaving the cell is generated and sent to the parent's mobile phone.

The user's location information is updated at 1:00 noon. Usually the child is at school at this time, so the location information is updated to the school address. When the child goes home from school, swipes the card on the bus, the watch obtains another NFC card swipe information, but according to the type of NFC analog card used, it can be seen that the NFC device just swiped is not the target NFC device, so no reminder message will be generated.

The child came to the gate of the community and swiped the gate of the community to enter the community. At this time, the watch obtains another piece of NFC card swiping information. According to the swiping position and the type of NFC analog card used, it can be known that the current NFC device is the target NFC device, that is, the access control device of the community.

According to the location information (= school) recorded in the watch and the location information (= cell) of the target NFC device, it is determined that the child is entering the cell, and accordingly, a reminder message for entering the cell is generated and sent to the parent's mobile phone.

In this embodiment, according to the user's NFC card swiping information, combined with the positioning function of the mobile terminal, the event of the user entering and leaving the target area can be accurately identified, thereby providing information reminders for the user's guardian more accurately.

In another embodiment of the present invention, as shown in Figure 2, an information reminder method includes:

Step S110 acquires the NFC card swiping information of the user in a preset time period, where the NFC card swiping information includes the swiping position and the used NFC analog card type.

Specifically, the user's NFC card swiping information refers to the card swiping information obtained by the user's mobile terminal when the user successfully uses his mobile terminal to swipe the NFC device.

The user's mobile terminal is a mobile terminal with an NFC function, including a wearable device such as an NFC mobile phone, an NFC watch/band, and the like. Such mobile terminals can be used as NFC simulated cards, such as simulated access control cards, transportation cards, bank cards and other cards.

NFC devices, compared to NFC analog cards, are used to exchange information with NFC analog cards to realize functions such as identity recognition and contactless payment, such as NFC card readers on buses, NFC card readers in community access control devices, etc. .

Every time the user performs a successful NFC card swiping operation using the mobile terminal, a card swiping message will be generated on the mobile terminal side. The card swiping information includes the card swiping location and the type of NFC analog card used.

The preset time period can be set according to needs, such as the time when the child's safety is at certain risk, such as the time to go to school and the time to go home after school. For example, children usually leave the community to go to school around 7:00 am from Monday to Friday, enter the community around 5:00 pm, and rest at home on Saturdays and Sundays. According to the time pattern, a preset time period is set on the user terminal , such as 6-8 in the morning from Monday to Friday, and 4-6 in the afternoon. By limiting the monitoring of NFC card swiping information only for a preset time period, it not only reduces the computing load of the terminal, saves the power of the user terminal, but also reduces unnecessary message reminders (for example, children are supervised on Saturdays and Sundays, and there is no need to remind them when entering and leaving the community. , redundant message reminders are also a distraction to parents).

Step S120 judges whether the swiping position of the NFC card swiping information is located in the target area, and whether the type of the NFC simulated card used is an access control card;

Step S130 When the swiping position of the NFC card swiping information is located in the target area, and the used NFC analog card type is an access control card, the current NFC device is a target NFC device; the target NFC device is an access control device in the target area.

Specifically, the target NFC device refers to an access control device in a target area with an NFC function. The target area can be preset. For example, assuming that the target area is cell A, the corresponding target NFC device is the access control device of cell A. It can obtain the user identity information of the access control card or access control analog card, and judge whether the user has the right to pass according to the user identity information. And when the user has the right to pass, it will be released.

When the swiping position is located in the target area and the NFC analog card type used is an access control card, the current NFC device is the target NFC device.

For example, it is assumed that the target NFC device is an access control device of cell A. When the user uses the mobile terminal to simulate swiping the bus card to get on the bus, a piece of card swiping information is obtained; according to the card swiping information, it can be known that the transportation card is used, so the current NFC device is not the target NFC device. When the user goes home and swipes the card successfully before entering and exiting the access control device in cell A, another card swiping information is obtained; according to the card swiping information, it can be seen that the access control analog card is used, and the swiping position is located in cell A, so it can be confirmed that the current NFC device is the target NFC device.

Step S210 obtains the location information recorded by the user before reaching the target NFC device;

Step S220 determines the passing direction of the user according to the recorded location information and the location information of the target NFC device.

Specifically, according to the positioning function of the mobile terminal, such as positioning means such as GPS or wireless base station, the position information recorded by the user before reaching the target NFC device can be obtained.

In an implementation manner, the location information of the user at a specific time is acquired and recorded, and the specific time can be correspondingly set according to a preset time period. For example, the preset time periods are 6-8 o'clock and 4-6 pm, and the corresponding specific times can be set to 5 am and 1 pm respectively, and the location information of the child at 5 am and pm can be obtained according to the positioning function of the mobile terminal. 1 point location information and record. Specifically, the location information of two time points can be recorded separately, and the user's traffic direction can be judged by selecting the location information closest to the current time point and comparing it with the target NFC device; Update the location information.

Further optionally, when the user's mobile terminal detects the WIFI at the user's home, the recorded location information is the home address. This method is more accurate than traditional GPS or base station positioning.

When both the recorded location information and the location information of the target NFC device are located in the target area, it is determined that the user's passing direction is to leave the target area. When the recorded location information is not located in the target area, it is determined that the user's passing direction is entering the target area.

In step S230, when the current NFC device is the target NFC device, corresponding reminder information is generated according to the user's travel direction, and the reminder information is sent to the associated terminal of the user.

Specifically, the user's associated terminal refers to other terminals bound to the user's mobile terminal. For example, the user is a child, and the mobile terminal used by the child's mother or father or his guardian is the child's associated terminal. Usually, the associated terminal is set on the child's mobile terminal, so that the guardian can know the safety situation of the child outside in real time.

The user's travel direction means that the user leaves the target area or enters the target area. The target NFC device is the access control device in the target area. Therefore, when the user swipes the card in front of the target NFC device, the corresponding reminder information can be accurately generated and sent to the user's associated terminal in time according to the direction of travel. The reminder information can also include the time when the event occurred. Compared with the traditional method of generating information reminders according to changes in user positioning information, this method can generate and send reminder information more accurately.

In this embodiment, by generating reminder information according to the user's NFC card swiping information in a preset time period, not only can information reminders be accurately provided for the user's guardian, but also the calculation amount of the terminal can be reduced, and the power of the user terminal can be saved.

In one embodiment of the present invention, as shown in FIG. 3 , an information reminder device 10 includes:

The device identification module 100 is configured to determine whether the current NFC device is a target NFC device according to the user's NFC card swiping information.

Specifically, the user's NFC card swiping information refers to the card swiping information obtained by the user's mobile terminal when the user successfully uses his mobile terminal to swipe the NFC device.

The user's mobile terminal is a mobile terminal with an NFC function, including a wearable device such as an NFC mobile phone, an NFC watch/band, and the like.

The target NFC device refers to the access control device of the target area with NFC function. The target area can be preset. For example, assuming that the target area is cell A, the corresponding target NFC device is the access control device of cell A. It can obtain the user identity information of the access control card or access control analog card, and judge whether the user has the right to pass according to the user identity information. And when the user has the right to pass, it will be released.

Every time the user performs a successful NFC card swiping operation using the mobile terminal, a card swiping message will be generated on the mobile terminal side. Optionally, the card swiping information includes the card swiping location and the type of the NFC analog card used. When the swiping position is located in the target area and the NFC analog card type used is an access control card, the current NFC device is the target NFC device.

For example, it is assumed that the target NFC device is an access control device of cell A. When the user uses the mobile terminal to simulate swiping the bus card to get on the bus, a piece of card swiping information is obtained; according to the card swiping information, it can be known that the transportation card is used, so the current NFC device is not the target NFC device. When the user goes home and swipes the card successfully before entering and exiting the access control device in cell A, another card swiping information is obtained; according to the card swiping information, it can be seen that the access control analog card is used, and the swiping position is located in cell A, so it can be confirmed that the current NFC device is the target NFC device.

The information generating and sending module 300 is configured to generate corresponding reminder information according to the user's traffic direction when the current NFC device is the target NFC device, and send the reminder information to the associated terminal of the user.

Specifically, the user's associated terminal refers to other terminals bound to the user's mobile terminal. For example, the user is a child, and the mobile terminal used by the child's mother or father or his guardian is the child's associated terminal. Usually, the associated terminal is set on the child's mobile terminal, so that the guardian can know the safety situation of the child outside in real time.

The user's travel direction means that the user leaves the target area or enters the target area. The target NFC device is the access control device in the target area. Therefore, when the user swipes the card in front of the target NFC device, the corresponding reminder information can be accurately generated and sent to the user's associated terminal in time according to the direction of travel. The reminder information can also include the time when the event occurred. Compared with the traditional method of generating information reminders according to changes in user positioning information, this method can generate and send reminder information more accurately.

Optionally, obtain the location information recorded by the user before reaching the target NFC device; and determine the passing direction of the user according to the recorded location information and the location information of the target NFC device. When both the recorded location information and the location information of the target NFC device are located in the target area, it is determined that the user's passing direction is to leave the target area. When the recorded location information is not located in the target area, it is determined that the user's passing direction is entering the target area.

According to the positioning function of the mobile terminal, such as positioning means such as GPS or wireless base station, the position information recorded by the user before reaching the target NFC device can be obtained.

One implementation is to acquire and record the location information of the user at a specific time. For example, the specific time is set to 6:00 am and 1:00 pm, and the location information of the child at 6:00 am and 1:00 pm is obtained and recorded according to the positioning function of the mobile terminal. Specifically, the location information of two time points can be recorded separately, and the user's traffic direction can be judged by selecting the location information closest to the current time point and comparing it with the target NFC device; Update the location information.

Further optionally, when the user's mobile terminal detects the WIFI at the user's home, the recorded location information is the home address. This method is more accurate than traditional GPS or base station positioning.

Taking a child going to school as an example, the current location of the user is obtained at 6 am. When a home WIFI signal is detected, it means that the child is at home, and the location information is recorded in the watch as the home address. The home address can be preset in the watch. The child leaves the house, comes to the gate of the community, and leaves the community by brushing the access control of the community. At this time, the watch obtains a piece of NFC card swiping information. According to the swiping position and the type of NFC analog card used, it can be known that the current NFC device is the target NFC device, that is, the access control device of the community.

According to the location information recorded in the watch and the location information of the target NFC device, it is determined that the child is leaving the cell, and accordingly, a reminder message for leaving the cell is generated and sent to the parent's mobile phone.

The user's location information is updated at 1:00 noon. Usually the child is at school at this time, so the location information is updated to the school address. When the child goes home from school, swipes the card on the bus, the watch obtains another NFC card swipe information, but according to the type of NFC analog card used, it can be seen that the NFC device just swiped is not the target NFC device, so no reminder message will be generated.

When both the recorded location information and the location information of the target NFC device are located in the target area, it is determined that the user's passing direction is to leave the target area. When the recorded location information is not located in the target area, it is determined that the user's passing direction is entering the target area.

The information generating and sending module 300 is configured to generate corresponding reminder information according to the user's traffic direction when the current NFC device is the target NFC device, and send the reminder information to the associated terminal of the user.

Specifically, the user's associated terminal refers to other terminals bound to the user's mobile terminal. For example, the user is a child, and the mobile terminal used by the child's mother or father or his guardian is the child's associated terminal. Usually, the associated terminal is set on the child's mobile terminal, so that the guardian can know the safety situation of the child outside in real time.

The user's travel direction means that the user leaves the target area or enters the target area. The target NFC device is the access control device in the target area. Therefore, when the user swipes the card in front of the target NFC device, the corresponding reminder information can be accurately generated and sent to the user's associated terminal in time according to the direction of travel. The reminder information can also include the time when the event occurred. Compared with the traditional method of generating information reminders according to changes in user positioning information, this method can generate and send reminder information more accurately.

In this embodiment, by generating reminder information according to the user's NFC card swiping information in a preset time period, not only can information reminders be accurately provided for the user's guardian, but also the calculation amount of the terminal can be reduced, and the power of the user terminal can be saved.

In an embodiment of the present invention, as shown in FIG. 5 , a mobile terminal 20 includes the information reminding apparatus 10 described in the foregoing embodiments.

In this embodiment, the information reminder device 10 accurately identifies the event of the user entering and leaving the target area according to the user's NFC card swiping information, so that the mobile terminal 20 can accurately provide information reminders for the user's guardian.

It should be noted that the above embodiments can be freely combined as required. The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. It should be regarded as the protection scope of the present invention.
