Example one
Please refer to fig. 1, which is a flowchart illustrating a method for controlling an electronic lock according to a first embodiment of the present invention, and for convenience of description, only a portion related to the first embodiment of the present invention is shown. The unlocking function includes but is not limited to touch password unlocking, radio frequency card swiping unlocking, human body biological information unlocking (such as fingerprint unlocking, face unlocking, iris unlocking and the like), and data communication unlocking (such as bluetooth unlocking, NFC unlocking and the like), and in order to achieve the above function requirements, the electronic lock needs to correspondingly design a corresponding circuit module in a circuit board specifically used by the electronic lock to achieve a corresponding function.
In this embodiment, referring to fig. 7 and 8, an element arrangement area 200 for intensively arranging elements is provided on one side of the circuit board, and an avoidance area 300 for avoiding elements is provided on the other side of the circuit board; the circuit board is centrally provided with various components on a first end surface of the component arrangement area 200; the circuit board is provided with a radio frequency coil 310 and a plurality of touch keys 320 arranged in an array on a second end surface of the avoiding area 300, each touch key 320 is diffracted inside and outside the radio frequency coil 310, and the second end surface is opposite to the first end surface.
At this time, in order to integrally set the independently set touch pad and the control main board, when the problems of high cost caused by the adoption of a double-layer circuit board and product failure caused by poor contact of a connector of the conventional electronic lock are solved, the components are intensively arranged in the component arrangement area 200, the touch keys 320 and the radio frequency coil 310 are respectively arranged in the avoidance area on the opposite side of the components, and at this time, because the touch keys 320 are diffracted inside and outside the radio frequency coil 310, the touch module using the touch keys 320 and the radio frequency module using the radio frequency coil 310 are arranged in the intersection area, so that when the electronic lock is used and works, the radio frequency power emitted by the radio frequency coil in the radio frequency module wakes up the touch module to work, and the touch module and the radio frequency module generate interference with each other The problem of interference.
The electronic lock work control method comprises the following steps:
step S10, when the controller enters the sleep mode, timing is started, and the controller is awakened after the preset sleep time;
in the embodiment of the present invention, the method for controlling the operation of the electronic lock is applied to an electronic lock, and is particularly applied to an MCU controller in the electronic lock, wherein the controller is electrically connected to each peripheral module in a circuit board to implement communication and control with each peripheral module circuit, and the peripheral module circuit includes, but is not limited to, a touch module, a radio frequency module, a fingerprint identification module, an iris identification module, a face identification module, a bluetooth module, an NFC module, a WIFI module, a ZIgBee module, a FLASH memory module, a eeprom memory module, and an encryption and decryption module. In the present embodiment, the touch module and the radio frequency module are mainly used, and the unreferenced portion of each of the other peripheral module circuits can be implemented by referring to the prior art, which is not limited herein.
The controller is provided with a sleep mode and a working mode, and when the controller is awakened to the working mode in the sleep mode or is dormant to the sleep mode in the working mode, the controller is clocked by an RTC real-time clock built in the controller. When the controller of the electronic lock enters the sleep mode, the controller utilizes the RTC to carry out timing, and when the timing reaches the preset sleep time, the controller is awakened, so that the controller is awakened from the sleep mode to the working mode, and at the moment, as the controller is in the sleep mode and the working mode at intervals, the standby power consumption of the electronic lock can be correspondingly reduced. The preset sleep time may be set to 0.5S, 1S or other times according to actual use requirements, which is not limited herein.
Step S20, when the controller is in the wake-up state, the radio frequency module is started, and whether the radio frequency module acquires the IC card information is detected within the started first preset wake-up time;
in the embodiment of the present invention, when the detection rf module acquires the IC card information within the first preset wake-up time, step S30 is executed; otherwise, step S40 is executed.
When the controller is in the sleep mode and sleeps for a preset sleep time at regular time, the controller wakes up to the working mode, at the moment, the controller controls to start the radio frequency module in the working mode, at the moment, the radio frequency module starts to work, the radio frequency module sends a radio frequency signal with a certain frequency through the transmitting antenna, when the IC card enters a working area of the transmitting antenna, induction current is generated, and the IC card obtains energy and is activated; the IC card sends out information such as self coding and the like through a built-in sending antenna of the card; the system receiving antenna receives a carrier signal sent from the IC card, the carrier signal is sent to the radio frequency module through the antenna regulator, the radio frequency module demodulates and decodes the received signal, and the like, so that the radio frequency module can detect the information of the IC card, at the moment, the controller detects whether the information of the IC card is obtained or not according to the received information transmitted by the radio frequency module, wherein the starting time of the radio frequency module is a first preset awakening time timed by RTC (real time clock), namely when the controller is awakened to a working mode, the controller immediately controls the radio frequency module to be started, and when the radio frequency module is started, the controller utilizes the RTC to time the first preset awakening time, when the IC card information is obtained within the first preset awakening time range, namely when the radio frequency module detects that a user swipes the card, the system executing step S30; otherwise, when the IC card information is not acquired until the first preset wakeup time, it executes step S40.
Step S30, according to the comparison between the IC card data read by the radio frequency module and each target IC card data stored in the electronic lock in advance, determining whether to unlock;
in the embodiment of the invention, when the radio frequency module acquires the IC card information within a first preset wake-up time range, the controller enters the electronic lock system, namely the controller compares the IC card data read by the radio frequency module currently with each target IC card data stored in a storage module in the electronic lock in advance, and when the comparison is successful, the electronic lock is controlled to unlock; otherwise, prompting that the card swiping fails and continuing to perform the card reading operation, namely, the radio frequency module continues to work, the controller still utilizes the RTC to perform timing at the moment, and when the IC card information is read again in a set timing range, the operation flow is performed according to the above steps; when the IC card information is not acquired until the first preset wake-up time, step S40 is executed.
If the number of times of continuous failure of comparison between the read IC card data and each target IC card data stored in the electronic lock by the controller is greater than the preset card swiping warning number of times, the controller controls to close the radio frequency module so as to stop detecting the card swiping operation of a user, meanwhile, the controller collects video image information of the user who swipes the card mistakenly at present through the image collection module, uploads the card swiping record and the video image information to a cloud or a user terminal using the electronic lock through data communication modules such as a WIFI module and the like so as to perform safety prompt on the user using the electronic lock, and meanwhile, the controller performs alarm through alarm modules such as a buzzer.
Step S40, turn off the rf module and switch on the touch module.
In the embodiment of the present invention, when the controller still does not acquire the IC card information after the controller times to the first preset wake-up time, the controller controls to turn off the radio frequency module and switch on the touch module, so as to detect whether the touch unlocking operation of the user exists through the touch module.
Step S50, detecting whether the touch module acquires a touch signal of the user within the second preset wake-up time.
In the embodiment of the present invention, when the touch module is detected to acquire the touch signal of the user within the second preset wake-up time, step S60 is executed; otherwise, step S70 is executed.
The touch keys corresponding to the touch module can be capacitive touch keys, inductive touch keys, infrared touch keys and the like, various signals generated when a user touches the touch keys are converted into touch signals, and if a human body approaches the capacitive touch keys with a specific key value, current generated by the human body is coupled to a static capacitor, so that the pressed capacitance value is maximized, and the converted capacitance value can transmit and convert the signals, so that the capacitance signals are converted into specific touch signals. The corresponding resistance-type touch key presses the resistor through a human body to cause the size of the resistor to change, and the change of the resistor causes the whole circuit signal to change, so that touch is realized. The corresponding infrared touch keys utilize the influence of light on current, each infrared touch key can generate light, and when a human body shades infrared light, the infrared light can control the current, so that touch is realized.
After the controller controls switching to start the touch module, the touch module starts working and detects whether a touch signal of a user is collected, wherein the starting time of the touch module is a second preset awakening time timed by the RTC, and when the touch module is used actually, the first preset awakening time and the second preset awakening time can be set to be the same or different, and are set according to actual use requirements without specific limitation.
And step S60, determining whether to unlock according to the comparison between each touch key value read by the touch module currently and sequentially and a target password value stored in the electronic lock in advance.
In the embodiment of the invention, when the touch module acquires the touch signal within the second preset wake-up time range, the controller enters the electronic lock system, that is, the controller controls the electronic lock to unlock when the comparison is successful according to the comparison between each touch key value read by the touch module currently and sequentially and the target password value stored in the electronic lock in advance; otherwise, prompting that the password is wrong and continuing the password touch operation, namely, the touch module continues to work, the controller still utilizes the RTC to carry out timing at the moment, and when the input touch key value is read again in the set range, the operation flow is carried out according to the above steps; when the input touch information is not read at the second preset wake-up time, step S70 is executed.
If the number of times of continuous failure of the comparison between each sequentially read touch key value and the target password value prestored in the electronic lock is greater than the preset touch warning number of times, the controller controls to close the touch module so as to stop detecting the touch password operation of the user, and simultaneously, the image acquisition module acquires video image information, the data communication module uploads safety prompt information, and the alarm module performs operations such as safety alarm.
Step S70, the touch module is turned off, and the sleep mode is entered.
In the embodiment of the present invention, when the touch module still does not acquire the touch signal after the timing reaches the second preset wake-up time, the controller controls to turn off the touch module and enters the sleep mode, and at this time, the step S10 is skipped to continue to execute the steps, so that the steps S10 to S70 are cyclically executed when the electronic lock is in operation.
It should be noted that, in other embodiments of the present invention, the controller may further start the touch module when waking up to the working mode after presetting the sleep time in the sleep mode, turn off the touch module and switch to start the radio frequency module when no touch information is detected within the second preset wake-up time, and enter into the sleep mode when no IC card information is detected within the first preset wake-up time. It can be understood that the sequence of the module circuits, which are required to be started at the first time when the controller is awakened, is set according to the actual use requirement, and is not specifically limited herein.
In this embodiment, the radio frequency module and the touch module are started by polling switching, and whether the radio frequency module or the touch module responds to the unlocking operation of the user is detected and judged, if so, the lock system is entered and whether the unlocking operation is performed is correspondingly determined, and if not, the lock system enters the sleep mode, so that the starting time of the radio frequency module and the starting time of the touch module are different, and interference between the radio frequency module and the touch module is avoided.
Example two
Please refer to fig. 2, which is a schematic flow chart of a method for controlling an electronic lock according to a second embodiment of the present invention, and for convenience of description, only the relevant portions of the embodiment of the present invention are shown, wherein the second embodiment of the present invention is substantially the same as the first embodiment, and for a brief description, reference may be made to corresponding contents in the first embodiment of the present invention, except that in the present embodiment, step S30 specifically includes:
step S31, when the IC card is read, the obtained ID information of the IC card is compared with each ID information prestored in the electronic lock;
in the embodiment of the present invention, the IC Card is an Integrated Circuit Card, also called an Integrated Circuit Card, and includes an ID identification area and a plurality of sectors. Wherein each sector is provided with a password checking area and a data storage area. ID information is stored in the ID identification area, password verification data is stored in the password verification area, and password data is stored in the data storage area.
When a user clings the IC card to the sensing area of the electronic lock or places the IC card near the sensing area of the electronic lock, the electronic lock reads the IC card. The sensing area of the electronic lock refers to the working area of a transmitting antenna in the radio frequency module, wherein each IC card is provided with one piece of ID information, the ID information of each IC card is different, when the electronic lock reads the IC card for the first time, the electronic lock can acquire the ID information of the IC card and store the ID information into a storage module of the electronic lock, and when the electronic lock reads the IC card through the radio frequency module, the electronic lock can acquire the ID information stored in an ID identification area in the IC card and then compares the ID information with each piece of ID information pre-stored by the electronic lock.
Step S32, when the ID information of the IC card is the same as one of the target ID information prestored in the electronic lock, the target password information corresponding to the target ID information is sent to the IC card, so that the IC card verifies the received target password information and the written password information;
in the embodiment of the invention, when the storage module in the electronic lock records the information of each IC card in advance, the storage module stores the ID information of each IC card and the password information corresponding to each IC card, at the moment, after the radio frequency module of the electronic lock acquires the ID information of any IC card, the electronic lock compares the ID information of the IC card with the ID information of each IC card stored in advance, when the comparison result is the same as one of the target ID information stored in advance, the electronic lock sends the target password information corresponding to the target ID information stored in advance to the IC card, and the IC card correspondingly verifies the target password information and the password data in the data storage area.
When the comparison result is different from the pre-stored ID information, namely the currently read IC card is not recorded in the electronic lock, the electronic lock prompts that the card swiping fails and continues to perform the card reading operation.
Step S33, determining whether to unlock according to the return value sent when the IC card is checked;
in the embodiment of the present invention, the step of determining whether to perform the unlocking operation according to the received return value sent when the IC card is verified specifically includes:
when a success value sent when the IC card is successfully verified is received, determining to carry out unlocking operation;
and (II) when the success value is not received, determining not to carry out unlocking operation, and correspondingly prompting that the card swiping fails.
When the IC card detects that the target password information sent by the electronic lock is the same as the password data of the data storage area of the IC card, the IC card sends a success value with successful verification to the electronic lock, the electronic lock correspondingly unlocks according to the received success value sent by the IC card, when the IC card verification is unsuccessful, the electronic lock does not send the success value or send a failure value with failed verification to the electronic lock, and when the electronic lock does not receive the success value or receives the failure value sent when the IC card verification fails, the electronic lock correspondingly prompts card swiping failure.
The target password information sent by the electronic lock is verified with the password data stored by the electronic lock through the IC card, so that the safety problem caused by unlocking operation when other people directly copy the ID information of the IC card is avoided, the difficulty of embezzlement of the copied IC card is increased through verification of the ID information of the IC card and the corresponding password information, and the use safety performance of the IC card and the electronic lock is improved.

step S51, when the touch signals are collected, sequentially reading touch key values corresponding to the currently collected touch signals;
in the embodiment of the present invention, in the circuit board described with reference to fig. 7, a plurality of touch keys arranged in an array are adopted, each of the touch keys corresponds to a touch key value, for example, touch key values such as ' 0 ' - ' 9 ' and ' # ', ' and the like, the touch key values are set according to actual use requirements, and no specific limitation is imposed on the touch key values, at this time, when a touch signal is acquired within the second preset wake-up time that is turned on, the touch key values input by the user are correspondingly read in sequence, for example, when the user presses the ' 7 ' touch key, the controller determines that the corresponding touch key value is ' 7 ' according to the corresponding determination of the touch signal.
Step S52, when the confirmation instruction of each sequentially input touch key value is acquired, determining the current unlocking password value according to each sequentially read touch key value;
in the embodiment of the present invention, the confirmation instruction may be triggered by a target touch key value, for example, when a user inputs a ' # ' touch key, the controller determines that the current user password input is completed according to the input ' # ' touch key value, and at this time, the controller determines the current unlocking password value according to each touch key value previously input by the user, for example, when the user sequentially inputs ' 012345#, the controller sequentially reads the acquired touch key values ' 012345 ', and when the ' # ' touch key value input by the current user is acquired, the controller determines that the current unlocking password value is ' 012345 ' according to each touch key value sequentially read.
It can be understood that, in other embodiments of the present invention, the confirmation instruction may also be determined according to the interval time of the adjacent input touch key values, for example, when the controller detects the touch information input by the user, the RTC is reused for timing each time the controller acquires the touch key value input by the user, when the controller does not acquire the touch information again within the target time timed by the last touch key value, the corresponding determination is that the password input is completed, and at this time, the current unlocking password value is determined according to each of the sequentially read touch key values, thereby avoiding the problem that the radio frequency module cannot be used and cannot perform the unlocking operation because the electronic lock is always in the state of acquiring the touch key values after entering the lock system but does not acquire the touch key values for a long time.
It should be noted that the number of bits of the unlocking password value is determined according to the actually set password of the user, and may be 6 bits, 8 bits or other numbers of bits, which is not limited herein.
And step S53, determining whether to unlock according to the comparison between the current unlocking password value and the target password value prestored in the electronic lock.
In the embodiment of the present invention, the step of determining whether to perform the unlocking operation according to the comparison between the current unlocking password value and the target password value pre-stored in the electronic lock specifically includes:
when the current unlocking password value is judged to be the same as the target password value, the unlocking operation is determined;
when the current unlocking password value is judged to be different from the target password value, determining that the unlocking operation is not carried out, correspondingly prompting that the password is wrong, and obtaining the unlocking password value input by the user again;
and (III) when the number of times that the unlocking password value is different from the target password value is judged to be larger than the preset number of times, closing the touch module in the target time period, and sending out a prompt alarm.
In the embodiment of the invention, the current unlocking password value input by the user is compared with the target password value prestored in the electronic lock, and when the comparison result is the same, namely the user inputs the password correctly, the electronic lock controls to unlock; when the comparison results are different, namely the user inputs the password wrongly, the electronic lock does not perform unlocking operation and prompts that the password is wrong, the user can input the password again, and when the controller detects that the number of times of the unlocking password mistake input by the user is greater than the preset number of times, the touch module is closed in the target time period, and the operation mode is used for performing safety alarm in sequence.
