Referring to fig. 1, the present embodiment provides a method for eliminating mutual interference between a touch panel and NFC, the method is applied to an intelligent door lock system, referring to fig. 2, the intelligent door lock system includes a touch panel 100 for sensing a finger touch signal, touch buttons 200 respectively disposed on the touch panel 100, an NFC card reader 300 for reading NFC card information, and a master MCU400, the master MCU400 is respectively connected to the touch panel 100, the touch buttons 200, and the NFC card reader 300, the method includes steps S10 and S20, which are described in detail below,
in step S10, the current sleep time of the intelligent door lock system is obtained, and when the current sleep time reaches the set sleep time, the main control MCU400 turns off the NFC card reader 300 to scan the NFC card information, turns on the touch panel 100 to scan the touch signal, and the intelligent door lock system enters the low power sleep state.
In step S20, when the finger or the NFC card approaches the touch panel 100, the touch key 200 preferentially triggers and wakes up the MCU400, and the MCU400 starts the time-sharing scanning of the NFC card reader 300 and the touch panel 100.
It should be noted that, in order to solve the problem that the NFC and the touch panel operate simultaneously and cause interference with each other, although the conventional technology adopts a method of scanning the NFC and the touch panel in a time-sharing manner, the method only solves the problem that the NFC and the touch panel interfere with each other before the smart door lock system enters the sleep state through the control of the main control MCU400, and the static power consumption is large; after the door lock system enters the low power consumption sleep state, the main control MCU400 also enters the low power consumption sleep state, and the interference problem cannot be solved at this time.
The method for eliminating mutual interference between the touch panel and the NFC can realize complete interference avoidance of the NFC and the touch in a dormant state of the intelligent door lock system, and the method is mainly applied to the intelligent door lock system, where the intelligent door lock system includes the touch panel 100, the NFC card reader 300, and the master MCU400, where the touch panel 100 can be used to sense a finger touch signal, for example, a user can input an unlocking password through the touch panel 100, and when the input unlocking password is the unlocking password set by the intelligent door lock system, the master MCU400 controls the electronic lock in the intelligent door lock system to complete unlocking, specifically, referring to fig. 3, the touch panel 100 can be provided with a plurality of keys, and when the unlocking password is only a pure digital password, the plurality of keys include 0 to 9 number keys, a delete key (corresponding to a key in the figure), and a confirm key (corresponding to a # key in the figure), when the unlocking password is a combined password of numbers and letters, the plurality of keys can also comprise twenty-six letter keys from a to z, and the corresponding setting can be specifically carried out according to the actual requirement, and the embodiment is not limited; the NFC card reader 300 reads the NFC card information, and when the read card information is card information authorized by the door lock system, the main control MCU400 controls the electronic lock in the intelligent door lock system to complete unlocking, specifically, the NFC card reader 300 may be disposed at a center of the touch panel 100.
The intelligent door lock system further includes a touch key 200, wherein the touch key 200 can be disposed around a plurality of keys of the touch panel 100, and the sensitivity setting is very high. According to the intelligent door lock system provided above, the method for eliminating mutual interference between the touch panel and the NFC provided in this embodiment is as follows: when the intelligent door lock system enters a dormant state, the NFC card reader 300 is completely closed to scan NFC card information, and only the touch panel 100 is opened to scan a touch signal; when a finger or an NFC card approaches the touch panel 100, the master MCU400 is awakened in time through the high-sensitivity touch key 200, the NFC card reader 300 and the touch panel 100 are immediately turned on through the master MCU400 for time-sharing scanning, that is, in one cycle, the NFC card reader 300 is turned off for scanning when the touch panel 100 scans, and then the NFC card reader 300 is turned on for scanning and the touch panel 100 is turned off for scanning.
Compare in the conventional art, this application before intelligent lock system gets into low-power consumption dormant state, the configuration NFC closes, only let the touch-control scanning, after whole intelligent lock system gets into low-power consumption dormant state, when pointing or NFC card is close to touch panel 100, touch button 200 is triggered earlier and awakens up entire system, open NFC and touch-control timesharing scanning immediately, thereby can effectively solve often because the problem that entire system was awaken up to NFC and touch-control mutual interference mistake after intelligent lock system is in dormant state, also can reduce the dormancy consumption simultaneously.
In one embodiment, when the distance between the finger or the NFC card and the touch panel 100 is 2.5cm to 3.5cm, the touch key 200 preferentially triggers the wakeup master MCU 400.
Specifically, when the distance between the finger or the NFC card and the touch panel 100 is 3cm, the touch key 200 preferentially triggers the wakeup main control MCU 400.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
