Referring to fig. 1 to 3, fig. 1 to 3 show a specific structure of the induction device for the intelligent interactive court according to the present utility model, which comprises a housing 1, a film pressure sensor 2, a controller 3 and an interactive module. Wherein, the upper surface of the shell 1 is provided with a datum point, and the upper surface of the shell 1 is recessed downwards from the edge towards the datum point to form a slope structure; the upper surface of the shell 1 is provided with at least one groove 11, and the film pressure sensor 2 is arranged at the bottom of the groove 11; the controller 3 is connected with the film pressure sensor 2 and the interaction module respectively through a wired (such as a data transmission line 4 in fig. 3) or wireless mode, and the controller 3 is used for acquiring sensing signals acquired by the film pressure sensor 2 and driving the interaction module according to the sensing signals.

In the practical application process, a user can throw a target sphere into the shell 1 at the periphery of the shell 1, the target sphere rolls along the upper surface of the concave part of the shell 1, and the target sphere can fall into one of the grooves 11 on the rolling path during rolling, so that the film pressure sensor 2 is triggered to collect sensing signals; at this time, the film pressure sensor 2 transmits the collected sensing signal to the controller 3, and after the controller 3 receives the sensing signal, the position of the sensing signal can be confirmed, and the corresponding interaction module is driven to interact.

The following details of the housing 1, the film pressure sensor 2, the controller 3, and the interaction module are described in detail below:

1. shell 1

The utility model designs the upper surface of the shell 1 into a concave structure with high edges and low middle, and can lead the target sphere to roll along the concave upper surface of the shell 1 towards the direction of the datum point after falling into the shell 1, thereby leading the target sphere to fall into different grooves 11. In the utility model, the datum point can be designed at the center of the upper surface of the shell 1, and the upper surface of the shell 1 is downwards recessed from the edge towards the datum point to form a cambered surface or conical surface structure, so that when a user puts a target ball into the shell 1 at the periphery of the shell 1, the user is in a high position, and the ball throwing operation is convenient. Preferably, the outer contour of the housing 1 can be designed into a circular structure, and when the datum point is designed at the center of the circular structure, the distance between the outer edge point of the housing 1 and the datum point is the same everywhere, so that the interaction safety and fairness can be effectively ensured.

Preferably, the groove 11 is an annular groove, and the datum point is located at the central position of the annular groove, so that the target team can be effectively guaranteed to enter the shell 1 at each position and fall into the groove 11, and the interaction effect is guaranteed.

In order to ensure that the target ball can fall into the recess 11 effectively, the angle α between the line between any point in the upper surface of the housing 1 and the reference point and the horizontal plane is 10 ° to 30 ° (see fig. 2). It should be noted that, too low an included angle can make the target sphere unable to overcome friction to slide freely, too large an included angle can reduce the contact area of the interaction area, and the possibility of crossing the groove 11 can also exist when the initial speed of the target sphere is too high, therefore, through the accurate limitation of the included angle, a height difference can be provided for the interaction area, so that the target sphere can fall onto the upper surface of the shell 1 conveniently and then roll down into the groove 11 freely by utilizing the height difference.

Correspondingly, the size of the shell 1 can be designed according to the actual area of the court, wherein the shell 1 comprises at least two mutually spliced sub-shells, and an interaction area can be formed by mutually splicing a plurality of sub-shells, so that the production difficulty of the single shell 1 is reduced, and the production cost is further reduced. Preferably, the sub-housing may be a fan-shaped structure or a ring-shaped structure (see fig. 4); for example, the interaction area can be spliced into a circular shape through a plurality of fan-shaped structures with the same size; for another example, the annular structures with different diameters can be spliced into a circular interaction area.

More preferably, the upper surface of the shell 1 is provided with a barrier 12 to divide the shell 1 into at least two sub-areas, so that the target sphere can be ensured to slide in each area, the partition interaction of different users can be realized, the interaction is not influenced, and the independence is stronger. Meanwhile, the isolation can be arranged at the splicing part of the sub-shells, so that the partition is convenient to detach or combine.

Further, a recovery channel 13 (see fig. 2) is further provided at the bottom of the housing 1, and the recovery channel 13 is communicated with the bottom of the groove 11, so that after hitting the film pressure sensor 2, the target ball falling into the groove 11 can reach the ball collecting place along the recovery channel 13, so as to realize rapid recovery of the target ball.

Preferably, the housing 1 may be manufactured by splicing an injection molded polymer material (e.g., engineering plastics such as nylon, ABS plastic, polycarbonate, polyoxymethylene, modified polyphenylene oxide, and thermoplastic polyester) or by engineering cement plastic construction, but is not limited thereto.

2. Film pressure sensor 2

The cost of the film pressure sensor 2 is far lower than that of sensing devices such as a frequency-emitting sensor, an infrared sensor, a laser sensor, an image recognition sensor and the like; meanwhile, the film pressure sensor 2 has the advantages of convenience in structural design, high customizable degree, simplicity in logic devices and the like.

According to the utility model, the film pressure sensors 2 are distributed at the bottom of the groove 11, and when a target sphere falls into the film pressure sensors 2 along the groove 11, the film pressure sensors 2 are subjected to the pressure of the target sphere, so that sensing signals are acquired once. Therefore, the utility model not only solves the problem of collecting the target ball, but also effectively reduces the use area of the film pressure sensor 2, is more convenient for personalized customization, can effectively reduce the cost of the whole device, also realizes the laying of a large-size court, has simple structure and is more convenient for later maintenance.

1. comprising a substrate, an electrode layer and a pressure-sensitive layer (see fig. 5);

2. comprising a substrate, an electrode layer, a pressure-sensitive layer, and a protective layer (see fig. 6);

3. including a substrate, an electrode layer, a pressure-sensitive layer, an electrode layer, and a substrate (see fig. 7);

wherein, the substrate can be made of PU, PE, PET, PI, nylon fiber and other flexible materials, the electrode layer can be made of silver paste, copper paste, conductive cloth and the like, the pressure sensing layer can be made of pressure sensing ink or conductive sponge, and the protective layer can be made of insulating ink, PU film, PE film, PET film or PI film, but the utility model is not limited thereto.

3. Controller 3

After receiving the sensing signal collected by the film pressure sensor 2, the controller 3 can perform logic judgment to provide a switching command for the matched interaction system.

4. Interactive module

It should be noted that, the interaction module includes a lamplight interaction sub-module, a sound interaction sub-module, a counting module and a track recording module, but the interaction module is not limited thereto, so long as the interaction effect can be achieved; wherein, the effects of lighting, lighting out, flashing and the like of the light can be realized through the light interaction submodule, the on-off effect of the sound can be realized through the sound interaction submodule, the number of the arrival times of the target sphere is recorded through the counting module, and the moving track of the target sphere is recorded through the track recording module, so that the flexibility is high.

Further, the interaction module may be disposed at different positions of the housing 1. For example, the indicator lights in the lamplight mutual sub-module can be arranged in the groove 11 and correspond to the positions of the film pressure sensors 2 one by one, when the target sphere falls into the position A of the groove 11, the film pressure sensors 2 in the position A collect sensing signals and send the sensing signals to the controller 3, and meanwhile the controller 3 drives the indicator lights in the position A to be lighted so as to prompt the position of the target sphere.

The utility model is described in further detail below in connection with specific examples:

example 1:

the utility model is applied to golf courses, interesting football courses, tennis courses and the like; the diameter of the interaction area is 22 meters, the shell 1 is made of engineering plastics (such as nylon, ABS plastic, polycarbonate, polyoxymethylene, modified polyphenyl ether and thermoplastic polyester) or engineering cement, the shell 1 is formed by splicing 3 fan-shaped sub-shells, and an included angle between a connecting line between any point in the upper surface of the shell 1 and a datum point and a horizontal plane is 10-30 degrees; the distance between the center points of the annular grooves 11 is 6-7 m, and the groove width of the annular grooves 11 is 30-100 cm.

When the target ball falls into the interaction area, the target ball rolls on the slope to enter the annular groove 11, the target ball passes through the annular groove 11 and contacts with the film pressure sensor 2, and the film pressure sensor 2 senses the pressure and then sends the sensing signal to the controller 3 for logic processing so as to provide switching signals (such as switching of lamplight, switching of sound, hit frequency display and the like) for the corresponding interaction module, so that the interaction effect of the equipment is improved.

Example 2:

the utility model is applied to a solid ball training field; wherein the diameter of the interaction area is 20 meters, and the shell 1 is made of compression-resistant engineering plastic or cement; the included angle between the connecting line between any point in the upper surface of the shell 1 and the reference point and the horizontal plane is 5-30 degrees. In the interaction area, 3 annular grooves 11 are arranged, the distance between the center points of the annular grooves 11 is 6-7 m, and the groove width of the annular grooves 11 is 50-100 cm.

When the lead ball falls into the interaction area, the lead ball rolls on the slope to enter the annular groove 11, the lead ball passes through the annular groove 11 and contacts with the film pressure sensor 2, the film pressure sensor 2 senses the pressure and then sends an induction signal to the controller 3 for logic processing so as to provide a switching signal for the corresponding interaction module, and the distance of the lead ball can be estimated or qualified.

Comparative example 1:

and a large-area film pressure sensor 2 is adopted for paving a large-size horizontal interaction area.

Because the height difference does not exist, the target sphere cannot roll down freely to the target position for collection; meanwhile, the large-area film pressure sensor 2 is high in laying cost, and the logic relationship of the controller 3 is complex; in view of the above, comparative example 1 requires higher cost and technical complexity.

Comparative example 2:

for a large-size horizontal interaction area, a level sensor such as laser, infrared, pattern recognition and the like is adopted to detect whether the sphere exists or not. The material level sensor is arranged in each corner of the large-size interaction area to realize full coverage of the sensing range, and whether the ball exists or not is identified through the material level sensor, so that a switching signal is provided, and the switching of the interaction module is controlled.

However, the level sensor required in comparative example 2 has problems that the cost is higher than that of the film pressure sensor 2, the matching is complicated, and the ball impact cannot be resisted.

Comparative example 3:

for the sensing device with height drop, the film pressure sensor 2 in the embodiments 1 and 2 is converted into a level sensor such as laser, infrared, pattern recognition and the like to detect whether a sphere exists or not; after the ball rolls down the slope into the annular duct, the level sensor recognizes the ball and provides a switching signal to the interaction module.

However, since a single level sensor cannot perform global detection on a large annular area, a plurality of level sensors need to be installed, and the cost is far higher than that of the film pressure sensor 2.

From the above, the utility model is suitable for large-size courts, and the area for paving the sensor can be effectively reduced by designing the slope of the sensing device and the structure of the annular groove 11, and the ball collection is realized; meanwhile, the film pressure sensor 2 is adopted at the bottom of the groove 11, so that signal acquisition can be realized, impact from a sphere can be resisted, and compared with sensors such as laser, infrared, pattern recognition and the like, the sensor has the advantages of good durability, low cost, simplicity in installation and simplicity in algorithm logic.

Correspondingly, the utility model further provides an induction system for the intelligent interactive court, which comprises at least one induction device.

It should be noted that, can set up independent induction system to a plurality of different interaction regions respectively to can effectively reduce sensor area of laying and cost, the flexibility is strong.

While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the utility model, such changes and modifications are also intended to be within the scope of the utility model.
