Description

TECHNICAL FIELD [0001] The present invention relates to a system and method for analyzing chip loss in an artificial turf field,

The present invention relates to a system for identifying a chip (filler) loss in an artificial turf field and a system for analyzing a user's activity in a turf field.

Generally, unlike natural grass, artificial turf does not need maintenance such as growing grass or pesticide, and it can be used semi-permanently. It also has advantages in terms of construction cost, and it is widely used in stadiums and school playgrounds . In recent years, artificial turf having superior texture and quality as well as natural grass has been popularized according to the development of technology, and the preference is increasing in various places regardless of workability.

Artificial turf is constructed in the form of grass filled with filler to provide elasticity to model lawn. Various elastic chips are used as filler. Conventionally, artificial chips such as rubber and waste tires have been mainly used as fillers, but in recent years, fillers made of eco-friendly natural materials such as yellow clay and rice husk have been popular.

In the artificial turf pitch, the filler chip provides similar resilience to the natural turf, thereby protecting the user's body by minimizing the amount of parts that the user can get on the ankles and ligaments during the exercise in the field . Therefore, when the filler chip is not uniformly distributed throughout the ground as in the initial construction, and a large amount is lost due to the influence of the user during the activity or the wind and rain, the possibility of user's body accident during the exercise is increased. For this reason, the administrator of the artificial turf ground periodically determines whether chips are lost or not, and takes measures (chip replenishment) related thereto. Conventionally, since it is necessary to discriminate the chip loss by human eyes, unnecessary management costs and time There was a problem that it increased greatly. Therefore, there is a need for a new method that can solve the inconvenience of visually discriminating whether or not the amount of filling material chips is lost in artificial turf pitches.

In addition, as the importance and awareness of the recent healthy life have greatly increased, people tend to check daily information on activity amount, activity time, and activity range according to their activities and use statistical information on them. In the past, statistical and systematic exercise management, which was applied only in terms of fitness management such as occupational athletes, has recently been extended to living athletes, clubs, and the general public for reasons of health. However, according to the related art, for the activity analysis or the like, the sensor is directly attached to the body of the user, and the activity amount is measured by a method of forcing the motion according to the specific sequence, or, even in a more generalized manner, (Heart rate, body temperature, exercise time, etc.) based on the measured exercise amount (or calorie consumption) was a way to check.

1 is a schematic view illustrating a chip loss chamber discrimination system according to a first embodiment of the present invention. Here, FIG. 2 is a block diagram of an embodied chip sensor device applicable to the chip loss chamber discrimination system of FIG. 1, and FIG. 3 is a block diagram of a field management server applicable to the chip loss chamber discrimination system of FIG. FIG. 4 is a reference diagram for explaining the embedding method of the buried chip sensor device, and FIG. 5 is a reference diagram for explaining the chip sensing method in the buried chip sensor device.

1 (A), a chip loss chamber discrimination system according to the first embodiment of the present invention includes a premises management server 100, a plurality of buried type chip sensor devices (not shown) communicatively connected to the premises management server 100 50-1, 50-2, ..., 50-n, hereinafter collectively referred to as reference numeral 50).

Here, the plurality of embedding type chip sensor devices 50 may be embedded at a predetermined position in the synthetic turf field to obtain sensing information for discriminating chip loss in the artificial turf field. Referring to FIG. 1 (B), the embedding type chip sensor device 50 is embodied in every artificial turf ground in a predetermined position. In this case, the position of the embedded chip sensor device 50 to be embedded and the number of the embedded chip sensor device 50 can be variously changed in consideration of system implementation design method, sensing accuracy, convenience of embedding (construction) A person skilled in the art (hereinafter referred to as a person skilled in the art) can easily understand it.

That is, FIG. 1B illustrates a case where a landing position is set in a grid form on the basis of an area in which players are mainly active by exemplifying a soccer field in which artificial turf is applied. However, If you do, you can set the landing position to match the defensive position of each player. In FIG. 1B, the embedded chip sensor devices 50 are shown as being embedded one by one in accordance with the main activity area of players, for convenience of illustration. However, (50) may be buried.

1 (A), a plurality of embedding type chip sensor devices 50 are communicatively connected to the ball court management server 100 via an intermediate communication interface device (refer to the interfacing unit of FIG. 1 (A)), It is also apparent that the flush-type chip sensor device 50 and the park management server 100 can be directly communicated with each other. At this time, the communication connection method (or the communication connection method via the interfacing unit) between the flush-type chip sensor device 50 and the field management server 100 does not depend on the wired connection method or the wireless connection method. For example, the plurality of embedded chip sensor devices 50 and the premises management server 100 may be directly connected to each other through wireless communication, and in the case of taking an intermediate mode, the interfacing unit and the premises management server 100 may perform wireless communication connection And the interfacing unit and the embedded chip sensor device 50 may be wired in a buried state.

2, the buried chip sensor device 50 according to an embodiment of the present invention includes a communication module 51, a sensor module 53, a drive motor unit 55, a control module 57, (59). 3, the premises management server 100 according to an embodiment of the present invention includes a communication interface unit 110, a ball game management DB 130, a ball game management controller 150, a chip loss amount determination unit 170, and a ball state determination unit 190. The block diagrams of FIG. 2 and FIG. 3 are merely examples, and some components may be omitted or some components may be added depending on whether the additional functional elements are added or not according to the system implementation design scheme. In addition, in the block diagrams of FIGS. 2 and 3, each constituent element is merely divided into functions according to functions of the invention, and two or more constituent elements may be integrated into one, As shown in FIG. This is also true for the block diagrams in the other drawings attached hereto. Hereinafter, functions and roles of the respective components in FIG. 2 and FIG. 3 will be described in turn.

2, the communication module 51 of the buried type chip sensor device 50 is configured to communicate with the communication interface unit 110 of the ballpost management server 100 in the direct communication method, A signal transmission / reception for chip loss determination is performed in relation to the interfacing unit. For example, the communication module 51 of the buried chip sensor device 50 receives the chip sensing start signal transmitted from the ball game management server 100 and transmits it to the control module 57, And transmits the sensed chip sensing information to the ballpost management server 100 under the control of the control module 57. [

The control module 57 of the embedded chip sensor device 50 also controls the overall function and operation of the embedded chip sensor device 50. For example, when the chip sensing start signal (that is, a command signal to start the sensing operation for chip loss determination) is received from the ball game management server 100 by the communication module 51, So that the chip sensing operation through the signal line 53 is started. The details of the chip sensing operation and the chip sensing method through the sensor module 53 will be described later with reference to FIGS. 4 and 5. The control module 57 transmits the chip sensing information obtained by the sensor module 53 to the ballpost management server 100 through the communication module 51. In the case where the chip sensing is performed in the sensor module 53 according to the chip sensing start signal, .

The power supply 59 of the buried chip sensor device 50 also serves to supply power to each component in the sensor device 50. In this case, the power supply unit 59 may include a charging circuit (not shown) that can load a self-power source (battery) and charge the power from a wired connection, or may include a power distribution circuit, And may be implemented to receive power.

The sensor module 53 and the drive motor unit 55 of the buried chip sensor device 50 will be described with reference to FIGS. 4 and 5. FIG.

The buried chip sensor device 50 is embedded within an artificial turf installation (see reference numerals 10, 20, 30, 40, and 22 in FIG. 4) as shown in FIG. 4, the artificial turf installation generally comprises a base layer 10, a synthetic turf mat 20, a turf model artificial turf pile 22, a support layer for fixed support of the artificial turf pile 22, (30), and a filler layer (40) filling and distributing an elastic filler chip on the support layer (30). At this time, the buried chip sensor device 50 can be buried in the lower part of the filling layer 40 filled with the filler chip in the artificial grass installation. 4 shows a case where the embedding material is buried in the supporting layer 30 under the filling layer 40. However, the embedding installation position may be variously changed according to the layer construction and / or the construction method of the artificial turf construction Of course.

At this time, the sensor module 53 may be fixedly installed at a predetermined position in the inner space of the probe 58, as shown in FIG. The probe 58 is housed in the probe housing case 58A in the embedded chip sensor housing 50. When the chip sensing start signal is received from the ball court management server 100, The driving force of the driving motor unit 55 by the driving motor unit 55 can be moved in the upward direction to be inserted into the filling layer 40.

The probe 58 has a height corresponding to the original thickness of the filling layer 40 (that is, the thickness of the filling layer at the time of initial application) so that the chip sensing through the sensor module 53 installed in the internal space can be accurately performed. ). ≪ / RTI > In this case, it is preferable that the mounting position of the sensor module 53 inside the probe 58 is disposed at the upper end of the probe 58 as much as possible (see FIG. 5 (A)). It should be appreciated that the probe 58 may have a length greater than the thickness of the fill layer 40 to the extent that the probe 58 does not have a length (height) less than the thickness of the fill layer 40, It is needless to say that the mounting position of the sensor module 53 and the detection signal to be output from the sensor module 53 can cover various ranges of the original thickness of the filling layer 40. [ Hereinafter, for convenience and concentration of explanation, description will be made with reference to the drawing shown in Fig.

5A, the sensor module 53 outputs a detection signal step by step according to a predetermined time interval (i.e., a specific height interval) in accordance with the ascending movement of the probe 58, (Receiving) the reflected signal reflected by the filler chip. As the sensor module 53, an ultrasonic transmission / reception module, an optical transmission / reception module, etc. may be utilized.

The chip sensing information sensed by the sensor module 53 is transmitted to the ballpost management server 100 through the communication module 51 under the control of the control module 57. [ At this time, as a transmission method of chip sensing information, there are a cyclic transmission scheme or an aperiodic transmission scheme (i.e., a scheme of transmitting information only when a predetermined event is generated, for example, only when sensing information judged as chip loss is acquired, Or the like) may be used.

When the chip sensing information acquired by the sensor module 53 is received, the ball game management server 100 transmits the chip sensing signal to the filling layer 40 based on the chip sensing signal according to the acupuncturing operation stepwise performed at the pre- And the chip loss amount can be calculated on the basis of the layer thickness information of the layered layer 40 converted.

The layer thickness conversion method and the chip loss amount calculation method can be performed in the following manner. That is, if the time of flight interval during which the reflection signal returns from the sensor module 53 is within a predetermined reference time, it can be confirmed that the filler chip is filled at the corresponding height (refer to FIG. 5 (Refer to H in FIG. 5). On the other hand, if the time interval during which the reflected signal returns is longer than the reference time (refer to the reflection signal reception case by the upper sensor module in FIG. 5B) (See the Loss position in FIG. 5). In this case, it is possible to calculate the layer thickness of the filling layer 40 and to calculate the chip loss amount, which can be performed by the chip loss amount discrimination unit 170 under the control of the ball game management controller 150 in the ball game management server 100 .

5A, only one sensor module 53 is installed in the upper internal space of the probe 58, and a detection signal is sent out stepwise at intervals of a predetermined time period from the sensor module 53 It is needless to say that other modifications are possible. For example, referring to FIG. 5B, a case where a plurality of sensor modules 53 are installed (refer to 53A and 53B) at a predetermined interval in the length (height) direction in the internal space of the probe 58 Respectively. 5B, when the probe 58 is completely moved up into the filling layer 40, the sensor modules 53A and 53B are operated simultaneously (at the same time), and the respective chip sensing signals (That is, a reflected signal). In this case, the chip loss amount can be determined only by a single sensing result.

Although the method of determining chip loss is mainly described above, the pitch management server 100 according to the embodiment of the present invention may also have a function of determining the ground state according to the surface temperature and water condition of the artificial turf pitch (See the ballpark state determination unit 190 in Fig. 3). For example, in the case where a temperature sensor (not shown), a moisture sensor (not shown), and the like are installed in the above-described flip chip sensor device 50 (for example, inside the probe 58) It is also possible to measure the temperature, the water content, and the like. In this case, the ball game management controller 150 of the ball game management server 100 stores information on the optimal temperature, water condition, chip filling state, etc., to be provided by the artificial turf pitches in the ball game management database 130, And the sensed values to generate guide information, alarm information, and the like for proper field management and provide the generated information to the manager.

FIG. 7 is a view for explaining a method of installing the signal collecting apparatus in the user activity analyzing system of FIG. 6, and FIG. 8 is a view illustrating an example of an operation analyzing server applicable to the user activity analyzing system of FIG. And FIG. 9 is a reference diagram for the user activity area (range) analyzed in the user activity analysis system of FIG.

6, a user activity analysis system according to an embodiment of the present invention includes an activity analysis server 200, a plurality of signal collection devices 70-1 , 70-2,..., 70-n, hereinafter collectively referred to as reference numeral 70). Here, the plurality of signal collecting apparatuses 70 may be an access point (AP), a repeater, and other radio signal transmitting and receiving apparatus such as RF.

At this time, the plurality of signal collecting apparatuses 70 collects the activity of the user located in a predetermined activity area (in this example, the stadium is exemplified hereafter) (in this example, Motion, and so on). To this end, the plurality of signal collecting apparatuses 70 are designed and installed so as to have wireless signal coverage covering the predetermined activity area so as to collect user activity related information within a predetermined activity area. Referring to FIG. 7, a total of four signal collecting devices 70 are dispersedly disposed at predetermined positions outside the soccer field. However, FIG. 7 is merely an example, and the installation position and the number of the installation can be variously modified. However, the number of the signal collecting apparatus 70 to be installed is determined based on the user's position (which is measured based on a signal sent from the wearable apparatus (see reference numeral 70 in FIG. 6 and FIG. 7) to be worn by the user) according to the triangulation method It is required that the minimum number of identifiable values be satisfied.

To this end, the plurality of signal collecting apparatuses 70 respectively measure reception sensitivity of a transmission signal transmitted from the wearable device 90 worn by the user, and transmit information about the measured signal reception sensitivity to the activity analysis server 200). Here, the user wearable wearable device 90 may be various, such as a wrist band type device, a hair band type device, a wear-and-fel-one-body type / attachment type device, and the like. At this time, the signal transmission interval of the transmission signal transmitted from the wearable device 90 may be fixed at a predetermined time period interval, but the time interval period may be shortened in proportion to the user's activity amount. For example, when at least one of the inertial sensor, the acceleration sensor, the angular velocity sensor, the gyro sensor, and the motion sensor is mounted on the wearable device 90, at least one of the user's activity amount and the activity speed is pre- A method of changing a signal transmission interval to be transmitted to the plurality of signal collecting apparatuses to shorter than a predetermined reference interval may be used. According to this method, if there is little user activity, adaptive control such as lengthening the signal transmission interval and shortening the signal transmission interval when the user's activity is increased can be performed, and the accuracy of the user's activity measurement can be improved The problem of battery consumption of the wearable device 90 can be solved.

8, the activity analysis server 200 includes a communication interface unit 210, an activity amount analysis unit 230, a user management DB 250, a location determination module 270, and a visualization processing unit 290 Can be implemented.

The communication interface unit 210 receives the signal reception sensitivity information measured from each of the plurality of signal collection apparatuses 70. Accordingly, the position determination module 270 determines the user position using the triangulation technique based on the signal reception sensitivity information about the same user received from each of the plurality of signal collection devices 70, The position change can be tracked in real time.

The activity amount analyzing unit 230 can calculate the activity range, activity frequency and activity time of the user based on the user location tracking result obtained by the position determination module 270. An example of this is shown in Fig. Referring to FIG. 9, a specific user wearing a wearable device at 90-k shows an example of a region of activity (ROA) played in a soccer field, and a dark gray activity Scope is the range of activities that have been intensively active when considering the frequency of activity by location.

6 to 8, the activity analysis server 200 in the activity analysis system according to the embodiment of the present invention tracks a user's activity position change in real time using a triangulation method, The amount of activity of the user can be analyzed. At this time, the analyzed information related to the activity amount can be accumulated and statistically made into a DB and managed as a DB (refer to the user management DB in FIG. 8). Also, the activity analyzing unit 230 of the activity analysis server 200 may calculate the activity rate of the user (for example, at each specific time point in the soccer game) , The cumulative activity distance, the amount of exercise (e.g., calorie consumption) associated therewith, and the like. Information on the individual activity range, the activity frequency per location, the activity time, the activity rate, and the amount of exercise calculated in this way is visualized (see the visualization processing unit 290 in FIG. 8) or statistically processed and transmitted to the communication device It is possible.

10 is a schematic view of a chip loss chamber discrimination system according to a second embodiment of the present invention.

10, the chip loss determination system according to the second embodiment of the present invention includes a premises management server 100B, an activity analysis server 200 communicatively connected to the premises management server 100B in a wired or wireless manner, , And a weather information management server (300).

In the chip loss determination system according to the second embodiment of the present invention, the basic configuration of the premises management server 100B is essentially different from the basic configuration of the premises management server 100 of the chip loss case determination system according to the above- It is not. However, in the chip loss determination system of the second embodiment, the chip loss determination is not performed based on the sensing information directly obtained from the embedded type chip sensor device 50 embedded in the artificial turf installation constructed in the artificial turf field, There is a difference between using indirect information to indirectly predict loss rate and chip loss.

Thus, in the chip loss determination system of the second embodiment, the premises management server 100B includes a component called the statistical table DB 130B, and the chip loss amount determination method in the chip loss amount determination unit 170B is the first Which is different from the embodiment. Therefore, the description that will be duplicated in the first embodiment will be omitted below, and the characteristic contents in the second embodiment will be mainly described.

In one example, the chip loss amount determination unit 170B of the ballpost management server 100B determines the amount of activity analysis information (for example, the activity analysis information) transmitted from the activity analysis server 200 as shown in Figs. 6 to 9, The activity frequency, and the activity time in the artificial turf field), the activity analysis information is converted into the activity intensity according to the position in the artificial turf field, and the activity intensity according to the position in the converted field The chip loss amount can be calculated based on a statistical reference table (stored in the statistical table DB 130B) that matches the loss amount of the filling chips.

For example, referring to FIG. 9, the fact that the activity intensity in the dark gray region is higher than the activity intensity in the light gray region implies that statistically, the amount of chip loss in the dark gray region can be increased indirectly It can be said that it shows. Therefore, the chip loss amount determination unit 170B of the second embodiment employs a method of statistically predicting the amount of chip loss based on the activity intensity for each activity position.

According to another example, the chip loss amount determination unit 170B of the ballpost management server 100B receives the precipitation information, the wind direction information, the wind direction information, and the wind direction information about the area where the artificial turf pitch is located from the connected weather information management server 300, (Which can also be stored in the statistical table DB 130B) that collects at least one of the weather information and the wind velocity information and matches the amount of fluid loss of the filled chip by weather information according to the collected weather information To calculate the chip loss amount. For example, considering wind direction and wind velocity information, it is possible to predict a certain amount of chip loss at a wind velocity above a certain speed and to predict a direction in which direction the chip will flow depending on the wind direction. Here, the weather information management server 300 may be a meteorological information server, but may be a specific external server (for example, a broadcasting station, an Internet portal server, etc.) that collects the primary weather information from the weather agency server and processes it as secondary weather information ).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims And changes may be made without departing from the spirit and scope of the invention.
