Referring to fig. 1, an NFC-based internet of things access control provided by an embodiment of the present invention is used for unlocking an intelligent door lock, and is often applied to hotels, homes, or office places. The internet of things entrance guard comprises a central processing unit 1, a battery 2, an I/O interface 3, a clock 4, a counter 5 and an NFC chip 6. The central processing unit 1 is connected with the intelligent door lock 7 through a controller 10; the battery 2 is electrically connected with the central processing unit 1 and used for supplying power to the entrance guard; the I/O interface 3 is electrically connected with the central processing unit 1 and used for input or output, so that man-machine interaction can be carried out, the use scene of the access control can be selected, the sleep awakening period of the NFC chip 6 can be set, and the like; the clock 4 is electrically connected with the central processing unit 1 and used for recording time; the counter 5 is electrically connected with the central processing unit 1 and is used for counting the opening times of the access control; the NFC chip 6 is electrically connected with the central processing unit 1 and used for carrying out data interaction with an unlocking source, opening the entrance guard under the successful data interaction and entering a dormancy awakening state under the failure of data interaction, wherein the dormancy awakening period of the NFC chip 6 is different under different use scenes.
Referring to fig. 2, the working principle of the NFC chip 6 is shown, specifically, the NFC chip 6 performs a cyclic operation according to a sleep wakeup period (e.g., 500ms or 1s) that is set to be completed, where one sleep wakeup period includes an emission state and a sleep state. Referring to fig. 3, taking 500ms as an example of a sleep-wakeup period for explanation, in the sleep-wakeup period of 500ms, the NFC chip 6 is in a sleep state in the previous 490ms, and at this time, the NFC chip 6 does not operate and consumes no or little electric energy of the battery 2; the NFC chip 6 is in a transmitting state in the last 10ms, at the moment, the NFC chip 6 transmits a 52 card searching instruction to search an unlocking source for data interaction, after the data interaction is successful, the entrance guard is opened, and after the data interaction is failed, the NFC chip enters a sleeping state of the next sleeping awakening period again to circulate.
It can be understood that, when the sleep wakeup period is different, the time lengths of the emission state and the sleep state are also different, in this embodiment, the time length of the emission state of the NFC chip 6 is always 10ms, and the time length of the sleep state changes with the change of the sleep wakeup period. For example: when the sleep wakeup period is 1s, the sleep state is 990ms, and the emission state is 10 ms; when the sleep wakeup period is 2s, the sleep state is 1990ms, and the emission state is 10 ms; when the sleep wakeup period is 3s, the sleep state is 2990ms, and the emission state is 10 ms. Of course, in other embodiments, the duration of the transmitting state and the sleep state may also be set according to needs, for example: when the sleep wakeup period is 1s, the sleep state may be 980ms and the transmit state is 20 ms.
In the above embodiment, the unlocking source includes at least a mobile phone and an unlocking card, for example: and an NFC chip is arranged in the mobile phone and used for data interaction with an NFC chip 6 of the entrance guard.

The power detection device 8 is electrically connected to the battery 2 through the central processing unit 1 for detecting the remaining power of the battery 2, and the remaining power of the battery 2 can be displayed through the I/O interface 3 (for example, data display is performed through a display screen). When the electric quantity detection device 8 detects that the residual electric quantity of the battery 2 is lower than a set value (for example, 5%), the central processing unit 1 transmits an alarm signal to the alarm device 9, the alarm device 9 is electrically connected with the central processing unit 1 and is used for receiving the alarm signal transmitted by the central processing unit 1 and executing an alarm program, so that an alarm prompt is given to a user, the alarm prompt can be in a sound prompt mode, an indicator light prompt mode and the like, and the alarm prompt is preferably an indicator light prompt mode in consideration of the fact that the sound prompt may affect daily life or work.
When the door control device is used specifically, after the door control device is electrified and initialized, a use scene (such as a family scene or an office scene) can be selected through the I/O interface 3, and then the sleep awakening period of the NFC chip 6 can be set in different modes according to different use scenes, so that the purposes of increasing the sleep time of the NFC chip 6 and reducing the power consumption are achieved in a software control mode. Meanwhile, when the entrance guard is out of power or the residual capacity of the battery 2 is too low, the alarm device 9 can warn to prompt the user to replace the battery 2 in time.
The method for setting the NFC-based internet of things access control in the present invention is described in detail below with reference to fig. 4:
referring to fig. 4, a setting method for an NFC-based internet of things access control provided in an embodiment of the present invention specifically includes the following steps:
s1: and E, electrifying and initializing the entrance guard of the Internet of things.
Specifically speaking, when thing networking entrance guard need use, with thing networking entrance guard power-on initialization, at this moment, show that thing networking entrance guard can begin to use, it can be first use, also can be the secondary usage after changing battery 2.
S2: the use scenario is selected through the I/O interface 3 to set different NFC sleep wakeup periods according to different use scenarios.
Specifically, after the internet of things access control is powered on and initialized, a use scene can be selected through the I/O interface 3, for example: input 1 represents a home scene, input 2 represents a public entertainment or office scene, and when entering different use scenes, the setting of the NFC sleep-wakeup period can be carried out in different modes.
The method specifically comprises the following steps of S21-S22:
s21: and when the use scene is a first scene, setting a sleep wakeup period of the NFC in a first mode.
Specifically, in this embodiment, the first scenario is a home scenario, and setting the sleep/wake-up period of NFC in the first manner specifically includes steps S211 to S212:
s211: initializing a clock 4 and a counter 5, wherein after each power-on initialization, a sleep wakeup period of NFC is a system default period (for example: 500ms), that is: after power-on initialization, the NFC chip 6 can circularly work by taking 500ms as a sleep wakeup period, and the default period of the system can be set according to needs;
s212: counting the opening times of the entrance guard in one day by a counter 5, wherein the counter is increased by one every time the entrance guard is opened, the counter is reset every morning at 24:00, and counting is started again;
s213: and the NFC dormancy awakening period of the new day is automatically matched according to the access control opening times of the previous day.
Specifically, when the opening times of the access control in one day per hour is smaller than X, corresponding to the hour, the sleep-wakeup period of the NFC is set to be a first duration (for example, 500 ms);
when the opening times of the access control in one day per hour is more than or equal to X and less than Y, setting the sleep and wake-up period of the NFC to be a second time length (for example, 1s) corresponding to the hour;
the opening times of the access control in one day per hour are more than or equal to Y and less than Z (when the time is longer than the hour, the sleep and wake-up period of the NFC is set to be a third time length (for example: 2 s);
when the opening times of the access control in one day per hour is more than or equal to Z, corresponding to the hour, setting the sleep and wake-up period of the NFC to be a fourth time (for example, 3 s); wherein X < Y < Z, and X, Y, Z are all positive integers (e.g., X ═ 2, Y ═ 5, and Z ═ 10);
when the fact that the entrance guard is not opened is retrieved for three consecutive days, the entrance guard is set to be in the leaving mode, the NFC function is forbidden, when the entrance guard is used again, the entrance guard needs to be opened by inputting a password through the I/O interface 3, so that the entrance guard enters the normal mode again, and the dormancy awakening period of the NFC is automatically matched according to the entrance guard opening times of the previous day.
Thus, the sleep wakeup period setting of the NFC chip 6 is completed in the first scenario.
Meanwhile, when the door lock is not powered or the battery 2 needs to be replaced, the process re-enters the step S1 to perform the power-on initialization operation.
S22: and when the use scene is a second scene, setting the sleep wakeup period of the NFC in a second mode.
Specifically, in this embodiment, the second scenario is a public entertainment or office scenario, and the setting of the sleep wakeup period of NFC in the second manner specifically includes steps S221 to S223:
s221: initializing a clock 4 and a counter 5;
s222: under the voice prompt, the sleep time interval is manually set through an I/O interface 3;
specifically, after the clock 4 and the counter 5 are initialized, a sleep period setting stage is entered, in which a user can set a sleep period through the I/O interface 3 according to his/her own needs under a voice prompt. For example: after hearing the 'dripping', the sleep starting time is set to be 10:00 in the morning, and after hearing the 'dripping', the sleep ending time is set to be 5:00 in the afternoon, so that the sleep time period set manually at this time is 10:00 in the morning and 5:00 in the afternoon. It can be understood that the setting manner of the sleep period described in this embodiment is only one of the simpler implementation manners, and in other embodiments, other manners of setting may be performed through the I/O interface as long as the same effect can be achieved.
Similarly, other times of day may be set by the same method, for example: setting 5:00 pm-10:00 pm as the second sleep period, setting 10:00 pm-5:00 am as the third sleep period, and setting 5:00 am-10:00 am as the fourth sleep period.
Thus, different NFC sleep wakeup cycles can be set at different sleep periods to reduce power consumption of the NFC chip 6.
S223: and aiming at different sleep periods, automatically matching the sleep and wake-up period of the NFC through the system, or manually and automatically setting the sleep and wake-up period of the NFC through an I/O interface.
The sleep wakeup period for automatically matching the NFC through the system specifically includes:
automatically detecting the opening times of the entrance guard in different dormancy periods through a counter 5, wherein the number of the opening times of the entrance guard is increased by one every time the entrance guard is opened, the counter is reset every morning at 24:00, and counting is restarted;
and the NFC dormancy awakening period of the new day is automatically matched according to the access control opening times of the previous day.
And in each sleep period, counting the opening times of the entrance guard in each hour by taking the hour as a unit, and taking the counted opening times as the sleep and wake-up cycle setting standard of the hour. Specifically, the setting process may refer to a sleep/wake cycle setting process in a home scenario, which is not described herein again.
Setting the sleep wakeup period of the NFC by a manual method specifically includes:
after entering the sleep wakeup period setting phase of NFC, under the voice prompt, the timing is started through the I/O interface, for example: the timing is started after hearing the sound of the 'drop' and the starting time t is recorded1；
When the expected time length is passed, the timing is ended through the I/O interface, and the ending time t is recorded2(ii) a Wherein the end time t2And a start time t1The time length between the first and second periods is the manually set NFC sleep wakeup period. When the expectation comesThe length is the waiting time that the user can bear, the longer the waiting time is, the longer the dormancy awakening period is, and otherwise, the shorter the dormancy awakening period is. Therefore, the sleep and wake-up period which meets the use requirement of the user can be set according to the self condition of the user.
And when the door control is not opened after retrieval for two consecutive days, setting the door control to be in an off-line mode, forbidding the NFC function, inputting a password through the I/O interface 3 to open the door control when the door control is used again so as to enter a normal mode again, and automatically matching the dormancy awakening period of the NFC according to the default time period of the system. At this point, manual setting of the NFC sleep wakeup period may be performed again.
And therefore, the sleep and wake-up cycle setting of the NFC chip 6 is completed in the second scene.
Meanwhile, when the door lock is not powered or the battery 2 needs to be replaced, the process re-enters the step S1 to perform the power-on initialization operation.
It can be understood that, in another embodiment, in the first scenario, the sleep/wake-up period of the NFC chip 6 may also be set in a second manner (i.e., a manual setting manner), and the specific process may refer to the setting process in the second scenario, which is not described herein again.
In summary, according to the NFC-based internet of things access control and the setting method thereof provided by the invention, a use scene (for example, a home scene or an office scene) is selected through the I/O interface, and then, the sleep wakeup period of the NFC chip can be set in different manners according to different use scenes, so that the purpose of increasing the sleep time of the NFC chip is achieved through a software control manner, and therefore, on the premise of not affecting normal use, power consumption is reduced, the use time of a battery in the access control can be prolonged, the replacement frequency of the battery is reduced, and the maintenance cost is saved.
The NFC-based internet of things access control and the setting method thereof provided by the present invention are explained in detail above.
