Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

In recent years, with the improvement of the quality of life of people, sports businesses are more and more popular with the public. On one hand, in order to better track the motion state of the athlete and the training safety, and perfect the compliance legitimacy aspects of sports meetings, running competitions and the like, the motion state needs to be monitored; on the other hand, people who love sports, especially the old and children, are prone to accidents such as collision and falling during sports, and if injury occurs during sports but no people are rescued, serious consequences which cannot be recovered can be caused due to the fact that timely rescue is not achieved. Therefore, monitoring of the exercise status is also particularly important for the general population.

That is, monitoring of the state of motion is critical to both professional athletes and amateur populations. In the current prior art, common monitoring modes of motion states mainly include manual monitoring and GPS monitoring.

The manual monitoring is that a manual mode is adopted, real-time monitoring is carried out on a sporter, the limitation of human resources and the vigor of a monitor is received, the problem of poor accuracy exists in the manual monitoring mode, and particularly, for large-scale competition and training, real monitoring on the motion state of each athlete is difficult to guarantee.

The GPS is a global positioning system, which is a satellite navigation positioning system, and by utilizing the system, a user can realize all-weather, continuous and real-time three-dimensional navigation positioning and speed measurement in a global range; in addition, with this system, the user can also perform high-precision time transfer and high-precision positioning. Currently, GPS positioning is a technology used for remote real-time positioning and monitoring of moving people, pets, vehicles, and equipment. GPS positioning is a positioning technology combining GPS technology, wireless communication technology (GSM/GPRS/CDMA), image processing technology, and Geographic Information System (GIS) technology.

The GPS technology is applied to the monitoring of the motion state, although the labor cost can be greatly reduced and the monitoring accuracy is improved, the GPS technology is mainly applied to outdoor motion scenes because the star searching can be completed only outdoors, and severe weather such as overcast and rainy weather can have great influence on the GPS, so that the monitoring accuracy is reduced, and the application range of the GPS technology in the motion state monitoring is further limited.

Therefore, a monitoring method capable of realizing a motion state with high accuracy is still relatively deficient. For example, the existing manual monitoring mode cannot provide safety guarantee and fair environment for behaviors such as falling and injuring during running, cheating and making a close route and the like. At present, the better race of marathon and the like is judged mainly by a GPS positioning mode, however, if the race encounters rainy weather or indoor environment, the defect of GPS positioning appears. Running or training fall injury at ordinary times, if peripheral when not having personnel to discover, can cause untimely treatment, bring loss and misery for the motion wounded.

On the other hand, the existing monitoring schemes for children, old people and vulnerable groups are mainly based on a manual management and monitoring mode, and in places such as kindergartens, nursing homes, hospitals and the like, due to the fact that the number of people is large, the number of workers and energy are limited, real-time monitoring cannot be conducted on all people, accidents are caused sometimes, and physical and mental benefits are damaged and property loss is caused due to the fact that people cannot be found timely.

In summary, the current method for monitoring motion state mainly has the following defects:

1. when people do running exercises or train injuries, people cannot timely inform work rescue in place; the rescue is not timely;

2. most of the existing monitoring work mainly depends on manual monitoring, real-time monitoring is not in place, and accidental discovery is not timely;

3. when an accident occurs, the alarm cannot be automatically given to remind workers to pay attention;

4. when the device approaches a dangerous area, related personnel cannot be specially reminded to take notice, and prevention cannot be done in advance;

in order to solve the above problems, in the embodiment of the present application, the UWB tag in the monitoring system may first detect the real-time motion parameter of the object to be monitored, which is set by binding, and once it is determined that the motion state is abnormal based on the real-time motion parameter, the alarm processing for the abnormal condition of the object to be monitored may be implemented through UWB communication between the UWB tag and the UWB base station, so that the accuracy of the motion state monitoring may be greatly improved, and the UWB tag may be widely applied to various scenes, thereby effectively improving the flexibility.

Before further detailed description of the embodiments of the present invention, terms and expressions mentioned in the embodiments of the present invention are explained, and the terms and expressions mentioned in the embodiments of the present invention are applied to the following explanations.

1. Ultra Wide Band (UWB) technology: a wireless carrier communication technology, it does not adopt the sine carrier, but utilize the narrow pulse transmission data of non-sine wave of nanosecond level, it has simple in construction of the system, transmit the low spectral density of the signal power, insensitive to the channel fading, capture the ability low, advantage such as being high of the positioning accuracy, UWB technology utilizes the extremely wide ultra wide baseband pulse of frequency spectrum to communicate, so also called the baseband communication technology, mainly used in the communication system of military radar, location and low capture rate/low detection rate.

2. Time Difference of Arrival (TDOA), TDOA location is a method of using Time Difference to perform location. By measuring the time of arrival of the signal at the monitoring station, the distance of the signal source can be determined. The location of the signal can be determined by the distance from the signal source to each monitoring station (taking the monitoring station as the center and the distance as the radius to make a circle). However, the absolute time is generally difficult to measure, and by comparing the absolute time difference of the arrival of the signal at each monitoring station, a hyperbola with the monitoring station as the focus and the distance difference as the major axis can be formed, and the intersection point of the hyperbola is the position of the signal.

3. Time of flight (TOF) technology is understood in a broad sense as a technology that further understands certain properties of ions or media by measuring the Time it takes for an object, particle, or wave to fly a certain distance in a fixed medium (both medium/distance/Time are known or measurable).

The TOF ranging method belongs to a two-way ranging technology, and mainly measures the distance between nodes by using the time of flight of a signal back and forth between two asynchronous transceivers (transmitters) (or reflected surfaces). The TOF ranging method has two key constraints: firstly, the sending device and the receiving device must be always synchronous; secondly, the length of the transmission time for the receiving device to provide the signal. In order to achieve clock synchronization, the TOF ranging method employs a clock offset to solve the clock synchronization problem. I is

4. Angle-of-Arrival ranging (AOA), a signal Angle-of-Arrival based positioning algorithm is a typical ranging based positioning algorithm, sensing the Arrival direction of a signal of a transmitting node through some hardware devices, calculating the relative orientation or Angle between a receiving node and an anchor node, and then calculating the position of an unknown node by triangulation or other methods. The positioning algorithm based on the signal angle of arrival (AOA) is a common self-positioning algorithm of the wireless sensor network node, and has low algorithm communication overhead and higher positioning accuracy.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

An embodiment of the present application provides a method for monitoring a motion state, where the method for monitoring a motion state may be applied to a monitoring system, where the monitoring system may include a UWB base station and a UWB tag, and the UWB tag is bound to an object to be monitored.

Fig. 1 is a schematic structural diagram of a monitoring system, and as shown in fig. 1, a monitoring system 10 may include a UWB base station 11 and a UWB tag 12, where at least one UWB base station 11 may be disposed in the monitoring system 10, and a position of each UWB base station 11 is fixed. Further, the monitoring system 10 may further include at least one UWB tag 12, and the at least one UWB tag may be bound to at least one object to be monitored, for example, if the object to be monitored is an old person, the UWB tag is integrated into a smart watch worn by the old person, so that the binding between the UWB tag and the object to be monitored may be implemented; if treat that the monitoring object is the long distance runner, then with the UWB label integration in the motion bracelet that this sportsman wore, alright in order to realize this UWB label and treat monitoring object's binding setting.

Further, in the embodiment of the present application, the monitoring system may further include a server, where the server may be configured to store the position information of the UWB tag acquired by the UWB base station, and may be further configured to perform subsequent processing on the position information of the UWB tag acquired by the UWB base station.

Fig. 2 is a schematic implementation flow diagram of a first implementation flow of a motion state monitoring method, as shown in fig. 2, in an embodiment of the present application, a method for performing motion state monitoring by a monitoring system may include the following steps:

step 101, the UWB tag obtains real-time motion parameters and judges whether abnormity exists according to the real-time motion parameters.

In the embodiment of the application, the UWB tag in the monitoring system may first acquire the real-time motion parameter, and then may determine whether the motion state of the object to be monitored is abnormal according to the real-time motion parameter.

It is to be understood that, in the embodiments of the present application, the UWB tag may be any terminal device integrated with the UWB module, and specifically, the UWB tag may not be limited to various types of terminal devices such as a notebook computer, a tablet computer, a desktop computer, a mobile device (for example, a mobile phone, a portable music player, a personal digital assistant, a dedicated messaging device, a portable game device, an in-vehicle device, and a wearable device).

Preferably, in the embodiment of the present application, in order to perform the monitoring of the motion state, the UWB tag may be a portable terminal device integrated with a UWB module, such as a smart watch, a smart bracelet, smart glasses, a mobile phone, and the like. Further, the UWB tag can also be installed as a module in an article worn by the object to be monitored, such as setting the UWB tag in a running shoe of a long distance runner, or setting the UWB tag in a wrist band of a badminton player, or setting the UWB tag in a crutch of an elderly person.

Further, in the embodiment of the present application, when the UWB tag detects real-time motion parameters of an object to be monitored, different sensors configured to acquire different parameters may be used to acquire the real-time motion parameters.

It should be noted that, in the embodiment of the present application, the real-time motion parameter acquired by the UWB tag in the monitoring system may include at least one of an acceleration parameter, a direction parameter, a gravity parameter, and an angular velocity parameter, that is, the UWB tag may acquire any one or more motion parameters of the object to be monitored through different sensors, and the application is not limited in particular.

For example, in the present application, when a UWB tag in a monitoring system acquires a real-time motion parameter, the UWB tag detects the acceleration parameter through an acceleration sensor; and/or, the UWB tag detects the direction parameter through a magnetic sensor; and/or, the UWB tag detects the gravity parameter through a gravity sensor; and/or the UWB tag detects the angular speed parameter through a gyroscope.

That is, in the embodiments of the present application, the UWB tag may be configured with at least one of a variety of different sensors, for example, the UWB tag may be configured with one or more of an acceleration sensor, a magnetic sensor, a gravity sensor, a gyroscope, and the like.

The action principle of the speed sensor is the same as that of a gravity sensor, the acceleration direction is determined through three dimensions, and the speed sensor is low in power consumption and low in precision. The method is applied to the terminal and can be used for counting steps and judging the direction of the terminal. The gravity sensor can be realized through a piezoelectric effect, can be used for switching the directions of a transverse screen and a straight screen, and can be used for applying data to a game through the induction of the horizontal direction to rotate the driving direction when being applied to a racing car game. The magnetic (field) sensor is used for measuring resistance change to determine magnetic field intensity, and can accurately judge by shaking the terminal when in use, and is mostly applied to compass and map navigation. Gyroscopes, which are capable of measuring angular velocity along one axis or several axes, are ideal technologies to supplement Micro-Electro-Mechanical systems (MEMS) accelerometers. The combination of the two sensors, namely the accelerometer and the gyroscope, can provide a more realistic user experience, an accurate navigation system and other functions for an end user. The functions of shaking and shaking in the terminal (for example, the terminal can be shaken to draw a lot), the motion sensing technology and the adjustment and detection of the visual angle of Virtual Reality (VR) are applied to the gyroscope.

Further, in the embodiment of the present application, when determining whether the motion state of the object to be monitored is abnormal, the UWB tag in the monitoring system may directly determine the motion state, or the server in the monitoring system may determine the motion state, and the present application is not particularly limited.

For example, in the present application, after acquiring the real-time motion parameter through the sensor, the UWB tag may directly determine whether the motion state of the object to be monitored is abnormal according to the real-time motion parameter.

For example, in the present application, after acquiring the real-time motion parameters through the sensor, the UWB tag may also synchronize the real-time motion parameters to a server in the monitoring system, and after acquiring the real-time motion parameters of the object to be monitored, the server may determine whether there is an abnormality according to the real-time motion parameters.

Fig. 3 is a schematic view of an implementation flow of the method for monitoring a motion state, as shown in fig. 3, in an embodiment of the present application, before the monitoring system determines whether there is an abnormality according to the real-time motion parameter, that is, before step 101, the method for monitoring a motion state by the monitoring system may further include the following steps:

105, setting a preset normal parameter range corresponding to the UWB tag; the preset normal parameter range is used for judging whether the object to be monitored falls or collides.

In the embodiment of the application, the monitoring system may first set the preset normal parameter range. Specifically, the preset normal range may be used to determine whether an abnormal motion condition such as a fall or a collision occurs to the object to be monitored. That is, if the real-time motion parameter detected by the UWB tag does not exceed the preset normal range, the monitoring system may consider that the object to be monitored does not have an abnormal motion condition of falling or impact; if the real-time motion parameters detected by the UWB tag exceed the preset normal range, the monitoring system can determine that the object to be monitored falls down or impacts abnormal motion conditions.

It can be understood that, in the present application, the preset normal parameter range may be a fixed and unchangeable motion parameter range, or may be a plurality of different motion parameter ranges set for different objects to be monitored. That is to say, for different objects to be monitored, the monitoring system sets the same preset normal parameter range, and may also set different preset normal parameter ranges, which is not specifically limited in this application.

For example, in the present application, when setting the preset normal parameter range, the monitoring system may set the preset normal parameter range for the UWB tag bound to badminton player a (a1, a2), may set the preset normal parameter range for the UWB tag bound to marathon player B (B1, B2), may set the preset normal parameter range for the UWB tag bound to pupil C (C1, C2), and may set the preset normal parameter range for the UWB tag bound to elder D (D1, D2).

It should be noted that, in the present application, different preset normal parameter ranges are set for different UWB tags, and different criteria of different scales can be used for different objects to be monitored, so that when determining whether a motion state is abnormal, a more accurate result can be obtained.

Further, in the present application, when the monitoring system determines whether there is an abnormality according to the real-time motion parameter, the monitoring system may compare the real-time motion parameter with a preset normal parameter range corresponding to the UWB tag, so as to determine whether there is an abnormality according to a comparison result. Specifically, if the comparison result is that the real-time motion parameter belongs to the preset normal parameter range, the monitoring system may determine that there is no abnormality in the motion state of the object to be monitored; if the comparison result is that the real-time motion parameter does not belong to the preset normal parameter range, the monitoring system can determine that the motion state of the object to be monitored is abnormal.

It should be noted that, in the embodiment of the present application, for different types of real-time motion parameters, different types of preset normal parameter ranges may be used, that is, the real-time motion parameters correspond to the types of the preset normal parameter ranges. For example, if the real-time motion parameter is an acceleration parameter, the preset normal parameter range is a numerical range corresponding to the acceleration; and if the real-time motion parameter is the gravity parameter, presetting the normal parameter range as a numerical range corresponding to the gravity.

Further, in the embodiment of the present application, if the real-time motion parameter includes a plurality of different motion parameters, correspondingly, the monitoring system needs to use a plurality of different preset normal parameter ranges to determine whether the motion state of the object to be monitored is abnormal, and when the plurality of different motion parameters all belong to the corresponding preset normal parameter ranges, it can be considered that the motion state of the object to be monitored is not abnormal; if any one of the plurality of different motion parameters does not belong to the corresponding preset normal parameter range, the abnormal motion state of the object to be monitored can be judged.

102, when judging that the abnormity exists, the UWB tag sends a first UWB signal to a UWB base station; wherein the first UWB signal carries an alarm request.

In the embodiment of the application, after the monitoring system judges whether an abnormality exists according to the real-time motion parameters, if the monitoring system judges that the motion state of the object to be monitored has the abnormality, the UWB tag in the monitoring system may send a first UWB signal to the UWB base station. Specifically, the first UWB signal carries an alarm request corresponding to an object to be monitored.

It is to be understood that, in the embodiment of the present application, the alarm request is used to notify the UWB base station of an abnormal state of the object to be monitored, so as to acquire the position information of the UWB tag using the UWB base station.

Note that, in the embodiment of the present application, the UWB tag and the UWB base station may be respectively provided with UWB modules, so that UWB communication may be established through the UWB modules to transmit and receive UWB signals.

UWB technology, among others, does not use a carrier wave, and transmits a data signal by transmitting nanosecond-level non-sinusoidal narrow pulses. The transmitter in a UWB system directly excites the antenna with small pulses without the up-conversion required by conventional transceivers, thereby eliminating the need for utility amplifiers and mixers. UWB systems allow the use of very inexpensive wideband transmitters. Meanwhile, at a receiving end, a receiver of the UWB system is different from a traditional receiver, and intermediate frequency processing is not needed, so that the UWB system structure is simpler to realize.

With UWB technology, it is easy to integrate positioning with communication, which is difficult to do with conventional radios. The UWB technology has extremely strong penetration capacity, can carry out accurate positioning indoors and underground, can only work within the visual range of GPS positioning satellites compared with the GPS, and can be applied to wider scenes. Unlike GPS, which provides an absolute geographic location, an ultra-wideband radio locator can give a relative location with a positioning accuracy of up to centimeter level.

And 103, determining the position information of the UWB tag by the UWB base station according to the first UWB signal.

In the embodiment of the present application, after receiving the first UWB signal transmitted by the UWB tag, the UWB base station may further determine the position information of the UWB tag from the first UWB signal.

It should be noted that, in the embodiment of the present application, the monitoring system includes at least one UWB base station, and therefore, a first UWB signal transmitted by the UWB tag may be received by all UWB base stations in the monitoring system, and then, one or more UWB base stations in all UWB base stations may perform positioning processing according to the first UWB signal, and finally determine the position information of the UWB tag.

It is understood that, in the present application, when positioning is performed by UWB technology, the commonly used positioning methods mainly include a plurality of algorithms such as TOF ranging positioning, TDOA positioning, AOA positioning, and the like, where TOF ranging positioning and TDOA positioning can be generally used separately, and AOA positioning is generally fusion positioning with TOF ranging positioning or TDOA positioning.

The TOF positioning is based on a ranging mode, the label and each base station needing positioning initiate ranging, and position calculation is carried out after ranging is completed. Wherein, in the zero-dimensional mode, only one base station is needed to measure the distance; in the one-dimensional mode, at least one base station is required to perform ranging; in the two-dimensional mode, at least three or more base stations are required to be subjected to ranging, and in the special mode, the ranging can be carried out with two base stations; in the three-dimensional mode, ranging with four base stations is required.

TDOA is based on time difference of arrival positioning, and a precise time synchronization function is required in the system. The time synchronization is performed through a wire, the wire time synchronization can be controlled within 0.1ns, the synchronization precision is very high, but all devices adopt a central network mode or a cascade mode due to the adoption of the wire, the complexity of network maintenance is increased, the complexity of construction is also increased, and the cost is increased. Moreover, a special wired time synchronizer is arranged in the system, so that the cost is high; the other method is to perform time synchronization wirelessly, the Wireless synchronization can generally reach 0.25ns, the accuracy is slightly less than that of wired time synchronization, but the system is relatively simpler, the positioning base station only needs to supply power, and the data return can be realized by a Wireless local area network (WiFi) mode, so that the cost is effectively reduced.

Specifically, after the UWB base station is time-synchronized, the UWB tag sends a broadcast message, and after the base station receives the broadcast message, the base station marks a timestamp of the received message, and sends the content to the calculation server, and the calculation server calculates timestamps of positioning messages of other base stations and calculates a position to be targeted.

AOA positioning generally calculates an arrival angle based on a phase difference, and is not generally used alone because AOA involves a problem of angular resolution, and the positioning accuracy is worse as the distance from a base station is farther in pure AOA positioning. Specifically, AOA can be used for positioning in coordination with TOF ranging, and in this mode, a single base station can complete positioning.

In the embodiment of the present application, when the monitoring system determines the position information of the UWB tag, the monitoring system may determine the position information of the UWB tag by using a plurality of UWB base stations in the monitoring system through cooperative processing, or may determine the position information of the UWB tag by using one UWB base station in the monitoring system through a combination of a plurality of positioning methods and using the received first UWB signal.

That is, in the present application, one or more UWB base stations in the monitoring system may further determine the location information of the UWB tag based on the first UWB signal by using one or more of time of flight TOF, time difference of arrival TDOA, and angle of arrival AOA.

And step 104, responding to the alarm request, generating a first alarm signal according to the position information, and sending the first alarm signal to complete the motion state monitoring of the object to be monitored.

In the embodiment of the application, after the UWB base station in the monitoring system determines the position information of the UWB tag according to the first UWB signal, the monitoring system may respond to an alarm request sent by the UWB tag, generate a first alarm signal according to the position information, and then may send the first alarm signal, so that monitoring of a corresponding motion state to be monitored may be completed.

Further, in the embodiment of the present application, when the first alarm signal is generated, the UWB base station in the monitoring system may directly perform the generation process, or the server in the monitoring system may perform the generation process, and the present application is not particularly limited.

For example, in the present application, after the UWB base station completes the determination of the position information of the UWB tag, the UWB base station may further generate the first alarm information according to the position information, so that the user may be notified of the position information of the object to be monitored where the abnormal condition exists by sending the first alarm information.

For example, in the present application, after the UWB tag is determined, the UWB base station may also synchronize the position information to a server in the monitoring system, and after the server acquires the position information of the object to be monitored, the server may further generate first alarm information according to the position information, so that the user may be notified of the position information of the object to be monitored, where the object to be monitored has an abnormal condition, through sending the first alarm information.

The embodiment of the application provides a method for monitoring a motion state, which is applied to a monitoring system, wherein the monitoring system comprises a UWB base station and a UWB tag, and the UWB tag is bound with an object to be monitored; the UWB tag acquires real-time motion parameters and judges whether abnormity exists according to the real-time motion parameters; when judging that the abnormity exists, the UWB tag sends a first UWB signal to the UWB base station; wherein the first UWB signal carries an alarm request; the UWB base station determines the position information of the UWB tag according to the first UWB signal; and responding to the alarm request, generating a first alarm signal according to the position information, and sending the first alarm signal to complete the motion state monitoring of the object to be monitored. That is to say, in the embodiment of this application, the UWB tag in the monitoring system can detect the real-time motion parameter of the object to be monitored that is bound and set up earlier, in case there is an abnormality based on the real-time motion parameter determination motion state, alright with UWB communication through between UWB tag and the UWB base station, realize the alarm processing to the abnormal condition of the object to be monitored to can improve the accuracy of motion state monitoring greatly, and can be applied to in multiple scenes widely, effectively promote the flexibility.

Further, in the present application, the preset posture condition may also be used to determine whether the posture is standard.
