The temperature sensor 180J is used to detect temperature. In some embodiments, the mobile terminal 100 executes a temperature processing strategy using the temperature detected by the temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the mobile terminal 100 performs a reduction in performance of a processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, the mobile terminal 100 heats the battery 142 when the temperature is below another threshold to avoid an abnormal shutdown of the mobile terminal 100 due to low temperature. In other embodiments, when the temperature is lower than a further threshold, the mobile terminal 100 performs boosting on the output voltage of the battery 142 to avoid abnormal shutdown due to low temperature.

The touch sensor 180K is also referred to as a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen".

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for determining an authority based on UWB according to an embodiment of the present application, and the method is applied to a mobile terminal including an ultra-wideband UWB module, and as shown in fig. 4, the method for determining an authority based on UWB includes the following operations.

S410, acquiring identity information of a target object, wherein the target object carries the mobile terminal.

Before the target object enters a certain area, the identity information of the target object required by the area can be acquired from a user information database which is stored in advance. If the database does not contain the identity information of the target object, the mobile terminal can request the target user to enter the identity information of the target user and store the identity information in the database. The identity information may include basic information of the user. The basic information may include: name, gender, identification number, age, contact number, address, etc., and for different scene areas, the identity information may further include the user's specific information, which may include: height, school number, job number, etc., for example, for a campus, the identity information may further include a user school number or a user number, and whether the user is a school member or not may be determined by identifying the user school number or the user number; for an office building area, the identity information can also comprise a user work number, and whether the user is an employee of the company, the level of the employee and the like can be determined through the work number; for parking lots, the identity information may also include the user's license plate number from which it may be determined whether the user is temporarily parked or permanently parked, and so on.

And S420, generating first authority information based on the identity information.

Wherein different places have different requirements on the user, for example, playgrounds have requirements on the age and height of the user; dormitory buildings have requirements on the sex of users; the school library has requirements on the number of multiple users or the number of the users. Therefore, for the requirement of the target area on the user, the special information entering the target area is acquired from the identity information of the target object, and the first authority information of the target object is generated based on the special information and the basic information.

S430, determining the position of the target object based on the UWB module.

Wherein the position of the target object can be measured by the UWB module, and the UWB module can periodically measure the position of the target object.

Optionally, the step S430 of determining the position of the target object based on the UWB module may include the following steps:

s31, the determining the position of the target object based on the UWB module comprises:

s32, receiving setting signals sent by K signal transceiver devices to obtain K setting signals, wherein the K signal transceiver devices are located in the target area, and K is a positive integer greater than 3;

s33, determining the flight time of each set signal to obtain K flight times;

and S34, determining the position of the target object based on the K flight durations.

The mobile terminal may include K signal transceiver devices in an area, where each signal transceiver device includes a UWB module. The ith signal transceiver device of the K signal transceiver devices may be used as a master transceiver device, the other K-1 signal transceiver devices may be used as slave transceiver devices, the master transceiver device periodically broadcasts a setting signal through a UWB module, and the setting signal may include device identification information for transmitting the setting signal and transmission time information for transmitting the setting signal. And after receiving a setting signal from the slave transceiver device, adding the device identification information of the slave transceiver device and the transmission time of the setting signal transmitted by the slave transceiver device into the setting signal, and broadcasting the setting signal after a preset time period.

And recording the receiving time of the setting signals sent by the K signal receiving and sending devices in the mobile terminal. The mobile terminal may calculate a flight time of the setting signal based on the receiving time of the setting signal and the sending time in the setting signal, and may know the signal transceiver device sending the setting signal based on the device identification information in the setting signal. The mobile terminal may determine the position of the target object based on the time of flight during which the signal transceiving equipment transmits the setting signal.

Optionally, determining the position of the target object based on the K flight durations may include:

establishing W distance difference equations based on the K flight durations, wherein W is a positive integer larger than 1 and smaller than K;

drawing W hyperbolas based on the W distance difference equations;

and determining the intersection point of the W hyperbolas as the position of the target object.

Wherein the distance difference equation is d_i,j＝(|t_j-t_i|+T_i*c_ij) C, the t_jSetting the flight time length of the signal from the jth signal transceiver device to the mobile terminal, t_iFor the flight time of the setting signal from the ith signal transceiver device to the mobile terminal, T_iA time difference for the mobile terminal to continuously receive the setting signal from the ith signal transceiver device, c_ijA ratio of a time difference between the setting signal being sent by the ith signal transceiver device and the setting signal being received from the jth signal transceiver device to a period of the setting signal being sent by the ith signal transceiver device, where c is a speed of light, j is a positive integer less than or equal to K, and j is not equal to i, and i is a positive integer less than or equal to K.

Furthermore, the positions of the K signal transceiver devices are fixed, the main transceiver device can send the setting signal according to a preset period, and the ith signal transceiver device is used for receiving the setting signalThe time difference between the transmission of the setting signal by one signal transmitting and receiving device and the reception of the setting signal from the jth signal transmitting and receiving device can be expressed as: the time difference is 2 × the flight time from the ith signal transceiver device to the jth signal transceiver device + the preset time, and the flight time from the ith signal transceiver device to the jth signal transceiver device may be measured in advance, so that the time difference c is obtained by subtracting the preset time from the flight time of the ith signal transceiver device to the jth signal transceiver device_ijMay be pre-measured.

Specifically, after the UWB module receives setting signals broadcasted by K signal transceiver devices, the mobile terminal calculates a flight time length of each setting signal to obtain K flight time lengths, and uses the ith signal transceiver device as a main transceiver device, calculates a difference between a receiving time of receiving the setting signal sent by the main transceiver device this time and a receiving time of receiving the setting signal sent by the main transceiver device in a previous cycle, and uses the difference as a time difference of continuously receiving the setting signal from the ith signal transceiver device, i.e., T_i. And then establishing W distance difference equations based on the K flight durations, and determining the intersection points of the W distance difference equations as the positions of the target object, wherein W is a positive integer smaller than K.

For example, as shown in fig. 5A, the signal transceiver 1 broadcasts the setting signal periodically according to T, and after receiving the setting signal, the signal transceiver 2 and the signal transceiver 3 retransmit the setting signal to the UWB module and the signal transceiver 1 in the mobile terminal. After the mobile terminal receives the setting signals sent by the signal transceiver device 1, the signal transceiver device 2 and the signal transceiver device 3, the mobile terminal takes the signal transceiver device 1 as a main transceiver device and takes the signal transceiver device 2 and the signal transceiver device 3 as auxiliary transceiver devices. The mobile terminal calculates the set signal according to the receiving time and the sending time of the set signal, and the flight time t to the mobile terminal sent by the signal transceiver 1, the signal transceiver 2 and the signal transceiver 3₁、t₂And t₃(ii) a According to again according to t₁、t₂And t₃The equation for the distance difference is as follows:

wherein d is₁₂For the difference in distance from the mobile terminal to the signal transceiving equipment 1 and from the mobile terminal to the signal transceiving equipment 2, d₁₃For the difference in distance from the mobile terminal to the signal transmission/reception device 1 and from the mobile terminal to the signal transmission/reception device 3, c₁₂For transmitting a setting signal to the signal transceiver device 1 measured in advance to receive a time difference T of the setting signal transmitted by the signal transceiver device 2₂Ratio to T, c₁₃For transmitting a setting signal to the signal transceiver device 1 measured in advance to receive a time difference T of the setting signal transmitted by the signal transceiver device 3₃Ratio to T, T₁The period of sending the setting signal for the mobile terminal to continuously receive the signal receiving apparatus 1, c is the speed of light.

Further, since the locus hyperbola of the moving point in which the distance difference from the two fixed points is constant can be obtained from d₁₂And d₁₃Determines the location of the mobile terminal. Specifically, the intersection of two hyperbolic equations may be taken as the position of the target object, as shown in fig. 5B.

S440, when the distance between the position of the target object and the target area is smaller than or equal to a first threshold, generating authorization indication information based on the first authority information, wherein the authorization indication information is used for indicating whether the target object is allowed to enter the target area.

The UWB module can periodically measure the position of a target object, and when the distance between the position of the target object and the boundary of a target area or the distance between the position of the target object and a gate access of the target area is smaller than or equal to a first threshold value, the first authority information is compared with the target authority information to generate authorization indication information, and the target authority information is authority information or an authority range required by entering the target area. If the first permission information meets the target permission information, the authorization indication information can be authorization pass; if the first permission information does not satisfy the target permission information, the authorization indication information may be that authorization does not pass.

For example, assuming that different places can be organized into different groups in a campus, the pass or the reject prompt can be performed according to different authentications, so that the authority identification can be performed at each place in the whole campus. Such as: a, entering a teaching building by the same school, and giving a passing right if the teaching building has the right; entering a doorway of a library, and refusing to enter the library if the entrance does not have the authority; when entering another dormitory building where no person is located, the user can confirm whether to pass according to the authority. As shown in fig. 6A, each Group is formed by a plurality of signal transceiver devices (e.g., UWB anchors) in a certain scene in a campus to form a small local area network (assumed to be Group 1), when a target object is a certain distance away from the range of Group1, the mobile terminal generates authorization indication information of the target object, and when the authorization indication information is successful, the target object may enter Group1, and in the whole process, the user only needs to approach to the coverage of Group 1.

In a possible embodiment, the method further comprises: when the first permission information comprises target permission information, entering the target area based on the authorization indication information; and sending a first message to a target device, wherein the first message is used for indicating the target object to enter the target area, and the target device is a reminding device in the target area.

The target device may be an electronic device for managing a target area, and the electronic device may be a mobile phone, a tablet computer, a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart home, and the like. The terminal device may also be a handheld device with a wireless communication function, a vehicle-mounted device, a wearable device, a computer device or other processing device connected to a wireless modem, a terminal device in a future 5G Network, or a terminal device in a Public Land Mobile Network (PLMN) for future evolution, and the like, which is not limited in this embodiment of the present application.

Specifically, when the first permission information includes the target permission information, the authorization indication information indicates that authorization is passed, and the target object can directly enter the target area. When the target object enters the target area, the mobile terminal may send a first message to the target device to indicate that the target object has entered the target area, where the first message may include at least one of authorization indication information, name, contact phone, identification number, school number, job number, and the like of the target object. The information included in the first message may also be different according to different regional scenarios, for example, when the target region is a dormitory building, the first message may include the name and/or school number of the target object; when the target area is an office building, the first message may include the name and/or job number of the target object.

For example, in practical applications, a plurality of dormitory buildings are usually present in a campus, and the check-in rate of rooms in the campus and whether students are in the dormitory need to be manually counted, which is very inefficient. By using the method provided by the embodiment of the application, when the target object enters the dormitory, the first message is sent to the dormitory management platform, and the first message may include the name and/or the school number of the target object. As shown in fig. 6B, the dormitory management platform can automatically count the occupancy rate of a certain building by receiving the first message sent by the target object carrying the mobile terminal. Meanwhile, whether all students live in a dormitory according to the specified sleeping can be counted, and intelligent management is achieved.

In one possible embodiment, the target area is a first area;

the method further comprises the following steps: and when the first permission information does not comprise target permission information and the target object enters the target area, sending a second message to target equipment, wherein the second message is used for giving an alarm to the target equipment and comprises the position of the target object and the identity information.

Wherein the first area may be represented as an area with access, such as a library, a dormitory building, an airport, an office building, a premium district, and the like. When the target area is an area with an access control and people without authority are prohibited from entering, if the target object does not have the authority to enter, namely the authorization indication information of the target object is not authorized to pass and the target object still enters the target area, the mobile terminal can send a second message to a platform or equipment for managing the target area to alarm, so that the safety of the target area can be ensured. And the second message can comprise the position of the target object and the identity information, and the manager can quickly lock the target object by acquiring the information, so that intelligent management is achieved.

In one possible embodiment, the target area is a second area;

the method further comprises the following steps: and when the first authority information does not comprise target authority information and the target object enters the target area, sending a first message to target equipment, wherein the first message is used for indicating the target object to enter the target area to the target equipment.

Wherein the second area is an area without access control, such as a teaching building, a mall, a park, an open stadium, a school playground, and the like. If the authorization indication information of the target object is that authorization is not passed, the target object has no authority to enter, but the target object still enters the target area, the mobile terminal may send a first message to a platform or a device for managing the target area to indicate that the target object has entered the target area. At least one of the authorization indication information, name, contact phone number, identification number, school number, job number, etc. of the target object can be included in the first message. The information included in the first message may also be different according to different regional scenarios. For example, when the target area is a teaching building, the first message may include authorization indication information, name and/or school number of the target object; when the target area is a park, the name and phone number of the target object may be included in the first message.

For example, as shown in fig. 6C, in a classroom, when each student enters a classroom, each student may send a first message to a target area, where the first message may include authorization indication information and a name of a target object, and after receiving the third message, the target device may display the third message according to the authorization indication information and the name, so that a teacher may accurately know the class arrival rate of the students and distinguish the situation of card punching by comparing the actual number of people with the number of people who punch a card.

In a possible embodiment, the method further comprises: and sending a third message to the target device, wherein the third message is used for requesting the permission to enter the target area, the first message comprises the identity information and time information, and the time information comprises the entering time and the leaving time.

In practical applications, there are some scenes in which the target object may need to enter the target area but has no authority, for example, a maintenance person performs an office building, a dormitory building, a library, a new person enters a company for work, and the like. In this scenario, the target object may apply for a temporary permission to enter the target area by sending a third message to a management platform or device that manages the target area through the mobile terminal, where the third message may include identity information of the target object, a reason for entering the target area, time, and departure time, and after the administrator checks the third message, the administrator may issue the temporary permission to the target object.

In a possible embodiment, the method further comprises: when the target object enters the target area, generating a motion track based on the position of the target object in a preset period; and sending the motion trail to the target equipment.

After the target object enters the target area, the motion trail of the target object can be monitored. Specifically, after the target object enters the target area, the position of the target object can be measured in real time through the UWB module, then a motion track is generated according to the measured position in a preset period, and the motion track is sent to the target device, so that a manager can monitor the motion track of the target object in real time.

For example, in a campus, a non-school person needs to enter the campus to handle things, and after the non-school person obtains temporary authority, in order to ensure whether the behavior is normal, the non-school person needs to monitor the behavior. Then the non-school person can be allowed to carry the mobile terminal when entering the campus area. Thus, the movement track of the non-proof personnel can be monitored. As shown in fig. 6D, the UWB module measures the position of the target object in real time, generates a motion trajectory according to the measured position, and transmits the motion trajectory, and a manager can monitor the motion trajectory according to the target object. Further, when the non-school personnel approach certain unauthorized places, a reminding notice can be given through the mobile terminal, and after the non-school personnel enter an unauthorized scene, a second message is sent to the target device to give an alarm.
