Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a wireless door lock and a power consumption control method thereof. Background Art

[0002] Traditional mechanical locks cannot detect the lock state in time and can only rely on manual inspection to check the lock state. In the case of being damaged, traditional mechanical locks cannot be discovered in time, which is likely to cause property losses or pose threats to personal safety. Different from traditional mechanical locks, wireless door locks not only have a mechanical lock body and an anti-theft alarm function, but also can comprehensively and real-time monitor the lock state by combining communication and positioning technologies. Wireless door locks are applied to industries such as vehicle transportation, and can perform functions such as locking and unlocking, entering and leaving the warehouse, patrolling the warehouse, and automatically uploading records through various methods, realizing information monitoring of in-transit transportation and warehouse management integration, and optimizing the transportation and warehousing management mechanism to a higher level.

[0003] Wireless door locks have mechanical components and electronic components and require a storage battery to provide energy. Due to the limited internal space of wireless door locks, the volume of the storage battery is restricted, and only limited electric energy can be provided. At the same time, in order to resist lock demolition and prevent dust and water, wireless door locks generally adopt a sealed structure, and the electronic components and the storage battery are enclosed inside the wireless door lock body structure, and the built-in storage battery cannot be quickly replaced. If the electric energy is exhausted during the use of the wireless door lock, it will not be able to work normally, which will have a great impact on the detection of the entire wireless door lock information. Especially during long-distance vehicle transportation, the positioning information and door lock state information of the lock cannot be obtained, thus causing major safety hazards in cargo transportation.

[0004] Therefore, in the case of limited electric energy stored in the storage battery, how to effectively reduce the power consumption of the wireless door lock has become a key technical problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to provide a wireless door lock and a power consumption control method thereof, which can effectively reduce the power consumption of the wireless door lock and ensure accurate and safe operation while reducing the power consumption.

[0063] Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0064] As Figure 1 shown, a schematic diagram of the basic structure of a wireless door lock is given. Generally, the wireless door lock includes a U-shaped lock beam 1 and a lock body 2. As Figure 2 shown, the lock body 2 includes: a mechanical unlocking mechanism 21, an electronic unlocking mechanism 22, a control circuit module 23 and a storage battery 24. The storage battery 24 supplies power to the electronic unlocking mechanism 22 and the control circuit module 23. The control circuit module 23 is configured to Figure 1 communicate and connect with the external user terminal 3 and / or the remote monitoring platform 4 as

[0067] According to different application scenarios, the wireless communication unit 2303 can be a Cat.1 unit, or a Cat.4 unit, or an eMTC unit, or an NB-IoT unit, or a LoRa unit. The full name of the Cat.1 unit is LTE UE-Category1, which is a level of user equipment UE under the LTE network. According to the definition of 3GPP, the UE categories are divided into 15 levels from 1 to 15. Cat.1 can be called a "low-end version" of 4G terminal, with an uplink peak rate of 5 Mbit / s and a downlink peak rate of 10 Mbit / s. It belongs to the cellular Internet of Things and is a wide area network. The ultimate goal of Cat.1 is to serve the Internet of Things and achieve the purpose of low-power and low-cost LTE connection.

[0137] S707: The control unit notifies the remote monitoring platform through the established network connection that it will use the network connection of the APP on the user terminal to connect to the remote monitoring platform.

[0138] Connecting to the remote monitoring platform through the user terminal via Bluetooth can reduce the power consumption of the wireless door lock on the one hand, and on the other hand, it can also reduce traffic consumption and obtain better network connection quality.

[0141] S710: The control unit actively disconnects the connection with the remote monitoring platform through the Cat1 network and shuts down the Cat1 unit.

[0142] Closing the Cat1 unit in the stationary state can reduce the power consumption, and the network connection is achieved through Bluetooth connection.

[0146] S714: Repeat steps S712 and S713 at intervals of 200 ms to obtain the acceleration arrays gx1, gy1, gz1, gx2, gy2, gz2--------gxN, gyN, gzN.

[0147] S715: Calculate the change rate of the acceleration in the three directions according to f(g) = |dg / dt|, where f(g) represents the acceleration change rate, g is the acceleration, and t is the time.

[0148] S716: If the APP on the user terminal is in a connected state with the control module of the wireless door lock and the change rate of the acceleration is less than or equal to 2, enter S711. If the APP on the user terminal is not in a connected state with the control module of the wireless door lock and the change rate of the acceleration is less than or equal to 2, enter S702. If the APP on the user terminal is in a connected state with the control module of the wireless door lock and the change rate of the acceleration is greater than 2, enter S717.

[0151] S719: Send an instruction to the Cat1 unit to put the Cat1 unit into the PSM mode, turn off the Bluetooth unit, turn off the NFC unit, turn off the display screen, and put the wireless door lock into the motion state.

[0152] Embodiment 3: Motion state control stage

[0153] As Figure 8 shown, the motion state control stage includes the following steps:

[0154] S801: Set the reporting interval of the Beidou positioning unit to T1 = 60 s;

[0155] S802: The control module of the wireless door lock reports the positioning status to the remote monitoring platform every T1. The reported information includes: indicating that the wireless door lock is in the motion state and cannot receive platform messages. At this time, the wireless communication unit, such as Cat1, turns on the PSM mode of periodic reporting and can report the positioning information and motion state information to the remote monitoring platform, and the remote monitoring platform can accurately know the running status and location information of the vehicle where the wireless door lock is located.

[0156] S803: Read the acceleration values of the acceleration sensor in the x, y, and z directions 10 times continuously and take the average of the ten times;

[0157] S804: Eliminate the data in the 10 acceleration values that are greater than 1.5 times the average value and less than 0.5 times the average value, and take the average of the remaining data to obtain gx, gy, and gz;

[0158] S805: Repeat steps S803 and S804 at intervals of 200 ms to obtain the acceleration arrays gx1, gy1, gz1, gx2, gy2, gz2--------gxN, gyN, gzN.

[0159] S806: Calculate the change rate of the acceleration in the three directions according to f(g) = |dg / dt|, where f(g) represents the acceleration change rate, g is the acceleration, and t is the time.

[0160] S807: If the rate of change of acceleration is greater than 3, turn off the acceleration sensor unit, set the reporting interval of the Beidou positioning unit to T2=1s, set the Cat1 unit from PSM mode to real network sleep mode, and receive messages from the remote monitoring platform. Report a message to the platform every T2. The message indicates that the device is in motion and can respond normally to platform messages; otherwise, enter S802.

[0161] When the acceleration change rate becomes larger, a more drastic speed change may have occurred, indicating that the vehicle where the wireless door lock is located is not in a stable operating state and an abnormal situation may have occurred. In this case, abnormal alarm information can also be reported and the information reporting cycle can be reduced so that the remote monitoring platform can be informed and check the vehicle operation status in a timely manner.

[0162] S808: Analyze the positioning data of the Beidou positioning unit to obtain speed information, and calculate acceleration A based on the speed information.

[0163] S809: If the absolute value of the acceleration is within 1 and the positive and negative values ​​are evenly distributed, it is considered that the vehicle where the wireless door lock is located is in a stable running state, and the acceleration sensor unit is turned on to enter S802.

[0164] S810: If the acceleration is greater than 1, the vehicle is considered to be in an accelerating state and the process proceeds to S808.

[0165] S811: If the acceleration is continuously less than 0, the vehicle is considered to be in a deceleration state. If the speed is reduced to 0 and lasts for more than 5 minutes, the vehicle enters a stationary state. Otherwise, the process enters S802.

[0166] Embodiment 4: Using the wavelet KAN network model to determine the current state according to the speed and acceleration.

[0167] The structure of the wavelet KAN network is similar to the traditional multi-layer perceptron (MLP), but the weights are replaced by wavelet functions, and the nodes sum these wavelet functions. Choose appropriate wavelet basis functions, such as Daubechies, Symlets, etc. These wavelet basis functions can effectively capture the high-frequency and low-frequency components of the data. Use discrete wavelet transform (DWT) for multi-resolution analysis to avoid the repeated calculation problem of continuous wavelet transform (CWT).

[0168] Collect the acceleration and velocity data of the wireless door lock, which can reflect the motion state of the wireless door lock at different time points. Clean the collected data to remove noise and outliers to improve the data quality. Use wavelet transform to extract features of acceleration and velocity data to obtain features of different scales. Generate corresponding labels according to the actual motion state of the wireless door lock, such as "acceleration", "deceleration", "constant speed driving", "turning", "fault", etc. The data is divided into training set, validation set and test set.

[0169] During model training, the preprocessed data and labels are input into the Wavelet KAN network for training. During the training process, appropriate optimization algorithms (such as Adam, SGD, etc.) and loss functions (such as mean squared error, cross-entropy, etc.) are used to continuously adjust the model's parameters to minimize the error between the prediction results and the true labels. By adjusting the model's hyperparameters, such as learning rate, batch size, number of network layers, etc., the performance of the model is optimized. The trained model is validated using a validation set, and metrics such as accuracy, recall, F1 value, etc. of the model are evaluated to determine whether the performance of the model meets the requirements.

[0170] After training is completed, the model can be tested in a real scenario to observe the performance of the model in actual applications. Some test data can be collected, including the motion state data of wireless door locks in different scenarios, and these data are input into the model to check whether the prediction results of the model match the actual situation.

[0171] The trained model is deployed to the control system of the wireless door lock, such as in the control circuit module, to monitor the motion state of the wireless door lock in real time, and to issue a warning signal in a timely manner when an abnormal state is detected for real-time monitoring and warning, reminding the remote monitoring platform to take corresponding measures to improve security. And the motion state determined by the trained model can be used as an auxiliary reference for the wireless door lock states in Embodiments 1, 2, and 3 to enhance the accuracy of state judgment.

[0172] When collecting the acquired speed data, time series data is usually obtained through sensors (such as speedometers). The wavelet transform is used to decompose the speed data to extract features of different frequencies. Wavelet decomposition can capture the high-frequency and low-frequency components in the signal to help identify the noise and trends in the data. Threshold processing is performed on the high-frequency part (detail coefficients) after wavelet decomposition to remove noise, effectively retain the main features of the signal, and at the same time reduce the influence of noise. The denoised signal is recombined using the wavelet reconstruction algorithm to obtain clearer speed data, preserving the integrity and accuracy of the data. Key features of the reconstructed signal, such as mean, variance, main frequency, etc., are extracted for subsequent analysis and verification. The processed speed data is compared with the original data to verify the effects of denoising and feature extraction. The accuracy of the data can be evaluated by calculating error metrics (such as mean squared error).

[0173] By applying the present invention, the power consumption of the storage battery can be reduced while ensuring the normal operation of the wireless door lock by optimizing the opening and closing of various electronic units in the control circuit module. The control circuit module performs power consumption management on the wireless door lock in the stationary state and the moving state by controlling the opening and closing of the positioning unit, the wireless communication unit, the Bluetooth unit, and the acceleration detection unit. At the same time, by adjusting the reporting period of the positioning information obtained by the positioning unit, the power consumption and the accurate monitoring of the state of the wireless door lock can be taken into account.

Examples of the computer-readable recording medium include: read-only memory, random access memory, compact disc read-only memory, magnetic tape, floppy disk, optical data storage device, and carrier wave (such as data transmission through the Internet via a wired or wireless transmission path).

[0175] In addition, according to an exemplary embodiment of the present invention, a computing device may also be provided. The computing device includes a processor and a memory. The memory is used to store a computer program.
