Detailed ways

In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

In some industries with high requirements for public services and confidentiality, such as banking, social security, confidential units and other working environments, employees are required to lock the screen when they leave their seats, but in actual work life there are always people who forget to hit the keyboard shortcut (WIN+L ) to lock the screen, so it is easy to cause computer data to be stolen and destroyed, resulting in the disclosure of personal or company privacy and confidentiality. In addition, it is necessary to enter a complex password to unlock the screen after returning to the workstation, which increases the complexity of the operation and reduces the work efficiency.

At present, there are some automatic screen lock and unlock technologies that can automatically lock the screen when there is no user in front of the computer. For example, an automatic screen locking and unlocking technology is to install an identification device on an office seat to realize the method and device for automatically locking and unlocking a computer. For example, a weight detector is installed on the office seat. When the weight of the object on the seat is less than a certain threshold, it can be considered that the user has left the seat, and the screen of the computer is locked. When the weight of the object on the seat is detected to be greater than a certain threshold, it can be considered that the user is in the In front of the computer, unlock the computer's screen. For another example, an automatic screen locking and unlocking technology is to install a proximity sensing module on a computer to detect when a person leaves and approaches to lock and unlock the computer screen. For another example, an automatic screen locking and unlocking technology is to connect an NFC card reader through a computer to obtain the NFC terminal ID and terminal unique identification number information, and to realize screen unlocking and screen locking after successful matching.

The inventor found in the research that the current automatic screen locking and unlocking technology is not perfect due to the existence of some defects. Specifically, by setting the weight detector on the seat to automatically lock and unlock the screen, the judgment error is large, and the sensitivity and security are low. It is easy for people of the same weight to unlock the computer screen. At the same time, the patent must be matched with a specific The seat can only be used. If the temporary seat is replaced, the screen cannot be unlocked/locked, which not only does not improve the user experience, but affects the normal function. Through the automatic locking and unlocking method of the proximity sensor module, the identity of the person cannot be identified, and the screen lock and unlock operation will be performed when any person approaches or leaves. This method can only solve the tedious steps of frequently unlocking/locking the screen, but without any security , it is easy to cause the leakage of key computer information. The method of automatically locking and unlocking the screen by connecting the NFC card reader to the computer requires the user to use the NFC terminal to operate at close range to realize the function. Similar to the original shortcut button function, it does not essentially solve the problem that the user forgets to lock the screen when he leaves. pain points.

Therefore, in order to improve the above-mentioned defects, the embodiments of the present application provide a screen control method and device, so that when a user is in a certain area of an electronic device, the electronic device automatically unlocks the screen and when the user leaves, the electronic device automatically unlocks .

Before introducing the embodiments of the present application, the technical terms involved in the embodiments of the present application are described first.

Ultra-wideband wireless communication technology (UWB), is a carrier-free communication technology, UWB does not use a carrier, but uses a short (nanosecond) energy pulse sequence, and the pulse is extended by orthogonal frequency division modulation or direct sequencing to A frequency range, so it occupies a large spectrum range. The main features of UWB are high transmission rate, large space capacity, low cost, and low power consumption. Contradictory technical means. UWB can be used to locate objects. The main advantages of UWB positioning are: low power consumption, insensitivity to channel fading (such as multipath, non-line-of-sight channels, etc.) It produces interference, has strong penetration (can locate in an environment that penetrates a brick wall), and has high positioning accuracy and positioning accuracy. UWB positioning is a real-time positioning technology, which can continuously report the current position data, which is very real-time. Furthermore, UWB positioning has ultra-high precision, and the positioning error is less than 10cm.

The time of flight (TOF) ranging method calculates the distance by measuring the flight time of the UWB signal to and from the two devices. Different from the Bluetooth and WIFI positioning methods, the location information obtained by UWB is not calculated based on the signal strength (RSSI), but is calculated by the precise wireless signal transmission time, reception time, and algorithm. Specifically, according to the mathematical relationship, the distance from a point to a known point is a constant, then this point must be on a circle with the known point as the center and the constant as the radius. It is assumed that the distance between two devices needs to be measured, and the two devices are the first device and the second device respectively. The first device first sends a ranging request to the second device, and the second device receives the ranging request for processing, and returns confirmation information to the first device after processing for a short period of time, and records the time interval between UWB signal transmission and reception, for example , the time interval between the first device sending a signal and receiving the response is recorded as T _TOT , and the time interval between the second device receiving the data packet and sending the response is recorded as T _TAT . Then the one-way flight time T _TOF of the signal in the air can be calculated as: T _TOF =(T _TOF -T _TAT )/2.

Angle of Arrival (AOA) positioning is generally based on the phase difference to calculate the angle of arrival. As shown in Figure 1, a transmitter B cooperates with two receivers A, and the signal arrival angle through the two receivers is The relative position of the transmitter can be determined in a two-dimensional plane. First, look at a receiver. The transmitter continues to send broadcast signals. The waveform received by the receiver's antenna array must be out of sync. The parameter obtained by the mathematical operation, the distance d between the other two receiving antennas is known. Through mathematical calculation, the relative angle between the planes where the transmitter and the two receivers are located in Fig. 1 can be calculated from the phase difference φ and the antenna distance d. As shown in Figure 2, A is two receivers, B is a transmitter, and the included angle between the plane where the two receivers A are located and the transmitter B is θ, specifically, θ can be the distance between the two receivers The angle between the middle position of and transmitter B, D is the distance between the middle position between the two receivers and transmitter B. θ ₁ is the angle between one receiver A and transmitter B, and θ ₂ is the angle between the other receiver A and transmitter B.

The calculation method of θ is as follows:

为上述相位差，d为两个接收机A之间的距离。in,

is the above-mentioned phase difference, and d is the distance between the two receivers A.

The system management unit is used to realize the comparison between the collection of the device identification and the preset identification in the library, and transmit the comparison result to the MCU for processing, as one of the judgment signals for unlocking the screen. The security processing unit implements user identity management, user account registration and cancellation processing, identity authentication processing, and the like. The algorithm management unit is used to realize secret key generation, operation, storage, data encryption and decryption, data signature, verification, etc. through general algorithm or national secret algorithm.

The MCU mainly has three functions: (1) Control the pairing of the UWB module with other devices, and store the pairing password for subsequent device pairing and comparison. The comparison result is used as one of the conditions for unlocking/locking the screen. (2) The device identification carrying the user equipment is transmitted to the security unit, and the security unit determines whether the device identification matches the preset identification in the identity database, and returns the judgment result to the MCU, and the judgment result is used as whether to release/lock The second condition of the screen. (3) Calculate the relative position of the user equipment relative to the electronic equipment through a preset algorithm, and send the relative position information back to the host, which is the third condition for whether to release/lock the screen.

The processor 110 (ie, the host) is used for receiving the judgment signal sent by the MCU, processing the signal, and controlling the unlocking/locking of the screen. When the pairing is successful, the identity information matches and the location information meets the threshold requirements at the same time, the host control screen is automatically unlocked. When any of the conditions cannot be met, the host controls the screen to automatically lock the screen, and continues to scan external paging at fixed time intervals, repeating the above judgment process.
