step S1, obtaining a start instruction, where the start instruction is sent by the main control module in response to a preset operation.
Install intelligent lock on the intelligence door of this embodiment, be provided with the lock system that is used for controlling intelligent lock on the intelligence lock, the lock system includes host system and communication module, host system and communication module connect. In specific application, the communication module is a wifi module, and the wifi module is electrically connected with the main control module.
And when the main control module receives a preset operation, sending a starting instruction to the communication module according to the preset operation. Specifically, the preset operation may be a digital unlocking operation that a user directly inputs to a door lock, or an unlocking operation through a non-contact NFC technology, or an unlocking operation that a door card is used to unlock the door lock, and the like, and when the main control module receives the preset operation, a start instruction is sent to the communication module, where the start instruction is used to start the communication module and to turn on a power supply for the communication module.
Further, as shown in fig. 2, the master control module monitors whether the door lock is operated, the master control module is provided with a door lock master control CPU, the door lock master control CPU is respectively connected with the communication module and the flash memory module, and is further connected with at least one of the fingerprint module, the card detection module and the key input module, and the preset operation is an unlocking operation as an example: the door lock master control CPU monitors the modules connected with the door lock master control CPU, judges whether unlocking operation exists in the key input module or not, or judges whether received fingerprint patterns exist in the fingerprint module or not, or judges whether intelligent card information is input in the card detection module or not, and judges that the door lock is operated if information input operation exists in the modules.
Furthermore, the preset operation can be other operations on the door lock besides the unlocking operation, for example, whether the intelligent door lock is prized or not, whether the intelligent door is alarmed or not, or other abnormal conditions occur on the door lock, and if the intelligent door lock operates in any condition, the main control module sends a starting instruction to the communication module.
And step S2, responding to the starting instruction, switching from a power-off state to a power-on state, and connecting with the monitoring terminal.
When receiving the start instruction, then host system is the communication module circular telegram, starts communication module, contain battery module in the lock, battery module is the host system power supply, be provided with the battery unit in the host system, the battery unit is used for supplying power to communication module, the battery unit is connected with a switch circuit, opening and closing of host system control switch circuit, work as when switch circuit opens, battery unit and communication module disconnection, communication module are in the outage state, work as when switch circuit closes, the battery unit is the communication module power supply, communication module is in the access circuit state.
And step S3, if the preset condition is met, switching from the power-on state to the power-off state.
When the communication module is powered on and meets the preset conditions, the power-on state of the communication module is switched to the power-off state, and the purpose of energy conservation is achieved. The preset condition may be that when the power-on time of the communication module exceeds the preset time, the communication module is controlled to be powered off, or when a power-off application signal sent by the communication module is received, the main control module controls the communication module to be powered off, or when the main control module monitors that the communication module transmits data to be transmitted to the monitoring terminal, the communication module is controlled to be powered off.
The data to be transmitted by the communication module is specifically data information received by the communication module from the main control module, the data information is corresponding to the preset operation, and after the main control module receives the preset operation, the data information corresponding to the preset operation is acquired and sent to the communication module.
When the communication module sends out the data information acquired from the main control module, the information of finishing data information sending can be automatically reported to the main control module, and when the main control module receives the reported information, the switch circuit is controlled to cut off the power of the communication module, so that the door lock is restored to the low power consumption state. Further, the data information may further include: unlocking password information corresponding to the unlocking operation.
Specifically, after the communication module sends the data information to the monitoring terminal, a signal indicating that the data information is successfully sent can be automatically reported to the main control module, and the main control module controls the switch circuit to power off the communication module. The master control module can also monitor the state of the communication module, and when the communication module is monitored to finish sending data information, the master control module automatically performs power-off operation on the communication module.
The data information corresponding to the preset operation is sent to the communication module through a serial port after being acquired by the door lock main control CPU from the fingerprint module, the card detection module and/or the key input module which are connected with the door lock main control CPU, and the data information is sent out after being acquired by the communication module.
The data information contains unlocking passwords, unlocking fingerprints, unlocking card IDs and other data information corresponding to unlocking operations, so that the communication module sends the data information to the monitoring terminal, a user can acquire the data information from the monitoring terminal by using the mobile terminal, the state information of the current door lock is obtained according to the acquired data information, and whether the door lock is abnormally unlocked or not is judged.
In another embodiment, if the communication module does not report the information that the data information is successfully sent to the main control module, the main control module may automatically time the power-on time after the communication module is started, and control the communication module to power off when the power-on time of the communication module exceeds a preset time. The preset time can be set as the time length of the unlocking operation of the user, and is generally set within 10 minutes.
Because the work flow of the communication module in the conventional intelligent door lock system is mainly as follows: electrifying- > connecting the router- > logging in the monitoring terminal- > monitoring serial port data. When the door lock is operated, for example, the door lock is unlocked or the lock is picked by someone, the communication module receives the serial port data, reports the serial port data to the monitoring terminal, and then the communication module is in a waiting state to wait for the arrival of the serial port data next time.
The method disclosed by the embodiment has the characteristic of low power consumption that the communication module is not in a always-on state, whether the communication module is powered on is determined by the main control module according to whether door lock operation is monitored, such as unlocking, prying a door by someone and the like, and if the communication module is powered on, the communication module is controlled to supply power
In one embodiment, the communication module is controlled as follows: when the master control module detects that someone opens the door or prizes the door, the master control module supplies power to the communication module and sends data information corresponding to door lock operation to the communication module through the serial port, the communication module is connected with a preset router immediately after being powered on, logs in the monitoring terminal, reports the received serial port data of the master control of the door lock to the monitoring terminal, and immediately informs the master control of the door lock of powering off the communication module after reporting. If the main control module does not receive the report information sent by the communication module within the preset time, the power of the communication module is automatically controlled to be cut off, for example: the door lock can directly power off the communication module within 15 seconds after the power supply is opened.
In order to better control the door lock, before the step of obtaining the starting instruction, the communication module further comprises:
and calculating an encryption factor through a preset encryption algorithm according to the MAC address and the equipment identification of the monitoring terminal and sending the encryption factor to the monitoring terminal and the main control module.
Specifically, when a user firstly connects a network with the door lock, at the moment, the communication module obtains an encryption factor through an encryption algorithm according to the mac address and the equipment identification of the communication module, the encryption factor is generated through information based on the mac address and the equipment identification of each communication module, so that the encryption factor of each door lock can be guaranteed to be different, and after the encryption factor is generated by the communication module, the encryption factor is sent to the main control module through serial port communication and sent to the monitoring terminal through communication.
The distribution network refers to that when a user adds a door lock to an application program installed on a monitoring terminal or a mobile terminal and used for door lock management, a random number is fixed and unchanged after being selected, when the user re-distributes the network, or when the door lock is added to the application program installed on the monitoring terminal or the mobile terminal again, the random number is regenerated, and when the user is replaced, an encryption factor is updated.
In one embodiment, the preset operation is an unlocking operation; after the step of responding to the starting instruction, switching from a power-off state to a power-on state and connecting with the monitoring terminal, the method further comprises the following steps:
receiving first data sent by a main control module, and sending the first data to the monitoring terminal, wherein the first data is a door lock state code sent by the main control module in response to the unlocking operation. The door lock state code corresponds to the opening and closing state of the door lock, and the opening and closing state of the door lock is determined by the main control module according to the received first temporary password and the second temporary password generated by the main control module.
The door lock state code represents the current state of the door lock, such as: when the door lock state code is 00, the current door lock is in a closed state, when the door lock state code is 01, the current door lock is in an unlocked state, the communication module sends the door lock state code to the monitoring terminal, the monitoring terminal can display the state of the current door lock according to the received door lock state code, and a user can know the use condition of the door lock by checking the door lock state displayed in the monitoring terminal.
Specifically, when the preset operation is the unlocking operation, the unlocking operation sent by the user is specifically the operation of inputting a first temporary password for unlocking, the main control module receives the first temporary password input by the user through the input module, compares the received first temporary password with a second temporary password generated by the main control module, judges whether the first temporary password is consistent with the second temporary password, controls the door lock to unlock if the first temporary password is consistent with the second temporary password, and does not execute the unlocking operation if the first temporary password is inconsistent with the second temporary password. The first data are door lock state codes sent to the communication module after the main control module judges that the first temporary password is the same as the second temporary password and performs unlocking operation or judges that the first temporary password is different from the second temporary password and does not perform unlocking operation, the communication module sends the door lock state codes to the monitoring terminal, and then a user can check the state of the current door lock by logging in the monitoring terminal.
Here, it should be noted that: and when the first temporary password is a temporary password generated by the monitoring terminal and is used within a set time, namely the first temporary password is the same as the second temporary password, executing unlocking operation.
Specifically, in order to achieve smooth unlocking, when the communication module is connected with the monitoring terminal, the real-time timestamp is acquired from the monitoring terminal, and the real-time timestamp is sent to the main control module, so that the main control module calibrates the local timestamp according to the real-time timestamp.
When the communication module is connected with the monitoring terminal at each time, the real-time timestamp is obtained from the monitoring terminal and is sent to the main control module, and the main control module calibrates the local timestamp on the system according to the real-time timestamp transmitted by the communication module. In this embodiment, the real-time timestamp is a time point when the communication module is connected to the monitoring terminal, but the setting of the timestamp is not limited in this embodiment, and the timestamp may be a time set manually on the monitoring terminal or a time set according to a time rule.
And after the main control module calibrates the local timestamp, a second temporary password is generated according to the encryption factor obtained from the communication module and a preset encryption algorithm.
And the monitoring terminal calculates a real-time temporary password by using a preset encryption algorithm at preset time intervals according to the received encryption factor, the real-time timestamp and the preset number, and updates the temporary unlocking password by using the real-time temporary password.
In order to realize that the unlocking password input into the intelligent door lock by a user is consistent with the first temporary password and the second temporary password generated in the main control module, the monitoring terminal calculates the obtained temporary unlocking password through a preset encryption algorithm at intervals of preset time according to the received encryption factor, the real-time timestamp and preset numbers, and after receiving a password checking instruction, the monitoring terminal sends the temporary unlocking password to the client. And the main control module generates a second temporary password according to the local timestamp, the encryption factor which is sent by the communication module and stored locally and a preset encryption algorithm. The user uses the temporary unlocking password obtained from the monitoring terminal to carry out unlocking operation, at the moment, the first temporary password input by the user is the temporary unlocking password obtained from the monitoring terminal, and as the encryption factors and the encryption algorithm used by the temporary unlocking password and the second temporary password obtained by the user are the same, the main control module compares the temporary unlocking password and the second temporary password to be the same, so as to control unlocking.
After the main control module receives the real-time timestamp sent by the communication module each time, the timestamp received before is updated, and the most accurate real-time timestamp is used for calculating the second temporary password when the temporary password is calculated each time.
Furthermore, the master control module also times the continuous operation time after the communication module is started, and controls the communication module to be powered off after the starting time of the communication module lasts for the preset time.
In another embodiment, the step of starting a communication module of the door lock and sending data information corresponding to the door lock operation through the communication module when the door lock operation is monitored includes:
and controlling the communication module to be electrified, and controlling the communication module to send the data information to a monitoring terminal, so that a user terminal obtains the data information from the monitoring terminal and displays the data information.
Before the communication module of the door lock is started, the switch circuit is controlled to supply power to the communication module, and after the monitoring terminal receives data information sent by the communication module, the user terminal obtains the data information from the monitoring terminal and displays the data information on the user terminal so that a user can check the state information of the door lock in time.
The control process of the present embodiment regarding the low power consumption of the door lock will be further described with reference to fig. 3.
When the master control module (which can also be a door lock master control circuit) can detect unlocking operations such as unlocking with a key, fingerprint unlocking, intelligent card unlocking and the like, and conditions such as lock picking or alarming of a door lock occur, communication between a serial port of the master control module and the communication module is established, data information corresponding to the unlocking operation is sent to the communication module, the communication module transmits the data information of the operation to the server end through the wireless network, the server end transmits the information to the app end, a user is informed of the real-time condition of the intelligent door lock, and meanwhile, after the communication module finishes sending the data information, the master control module controls the communication module to be powered off, so that the door lock enters a low power consumption state again.
The control method for unlocking based on the timestamp in this embodiment is further explained with reference to fig. 4. When the method is specifically implemented, the unlocking of relatives and friends of the user by using the temporary password can be realized.
Firstly, when the intelligent door lock is accessed to a network for the first time and is in communication connection with a monitoring terminal, a communication module of the intelligent door lock automatically generates an encryption factor according to a mac address of the network where the intelligent door lock is located and a random number added to the equipment ID of the communication module or a main control module by using a preset encryption algorithm, and the communication module sends the generated encryption factor to the main control module.
Meanwhile, the communication module uploads the encryption factors to the cloud server, and the cloud server can ensure that the encryption factors obtained in the main control module and the cloud monitoring terminal are the same due to the fact that the encryption algorithm, the mac address and the equipment ID used in the steps are the same, but the encryption factors of each door lock are different due to the fact that the mac address of each door lock is different and the equipment ID is different, the encryption factors are sent to a door lock main control program through a serial port, and the encryption factors are reported to the cloud server.
Communication module is when awakening up at every turn, acquires the real-time timestamp of high in the clouds server, and this real-time timestamp is used for the door lock master control to generate interim password used, and host system keeps the timestamp update at local after acquireing real-time timestamp to when communication module was awaken up at every turn, the timestamp is updated in step.
When the cloud server generates an unlocking password according to an encryption factor sent by the communication module and a real-time timestamp and according to a preset encryption algorithm, the unlocking password is sent to the user terminal after being generated, the user sends the unlocking password displayed in the user terminal to friends and relatives, the friends and relatives of the user carry out key input on the door lock for the unlocking password, the door lock carries out matching verification on the unlocking password and a temporary password generated according to the own encryption factor and timestamp when detecting the input unlocking password, and if the unlocking password is consistent, the unlocking password is effective and can be successfully unlocked.
For example: time stamping: 201910221658, encryption factor: dhaajls, in a cloud monitoring terminal: according to the real-time timestamp 201910221658 and the encryption factor dhaajls, a six-digit number 892455 is obtained through a two-party agreed algorithm, and the algorithm can be set to change the obtained number every few minutes. Such as one set for a 10 minute change. Such as: between 20: 50 and 17:00 on month 10/2019, ten minutes, the 892455 produced was fixed, and the door lock end: the temporary password 892455 is calculated according to 201910221658+ dhaajls, and the door can be opened when the password is consistent with the password taken by the user.
Above, app generates the process of interim password to the user use interim password, need not pass through the network, communicates through communication module, has realized communication module when not supplying power, also can realize passing through app by the owner of lock and temporarily generate the password in order to supply relatives and friends to use temporarily, has reached the interim password function under the low-power consumption communication module mode.
