[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present invention. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods.

For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0037] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment and do not mean essential composition and / or sequence.

[0038] The serial numbers assigned to the components in this text, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present invention, unless otherwise specified, both include direct and indirect connection (coupling).

[0039] Reference Figures 1 - 3 , this application provides a barrier-free middle and long-distance running test end controller 1000, which is used to cooperate with a moving carrier carrying a signal receiving component 3000 to achieve the measurement of the time used for middle and long-distance running. It includes a housing 1100, a shielding cover 1300, a microwave motion sensor 1400, and a main control board assembly 1700. The housing 1100 has an installation cavity 1110, the shielding cover 1300 is arranged in the installation cavity 1110, the shielding cover 1300 includes a shielding cavity 1310, the shielding cavity 1310 has a preset reflection track, the microwave motion sensor 1400 is arranged in the shielding cavity 1310, and is used to transmit a beacon frame with a packet number at a specific frequency and with a specific power at a preset interval time. The beacon frame can be reflected and constrained along the reflection track and exit to a preset end area. The main control board assembly 1700 is electrically connected to the microwave motion sensor 1400 and is used to control and adjust the intensity of the beacon frame transmitted by the microwave motion sensor 1400.

[0040] Through the setting of the shielding cover 1300, the beacon frame with a packet number transmitted by the microwave motion sensor 1400 at a specific frequency and with a specific power at a preset interval time can be reflected and constrained, so that it can accurately exit to the preset end area, thereby improving the accuracy of the test results. By using the end controller 1000 to replace the traditional signal receiving box and signal receiving carpet, the device structure is simplified, the layout is made more convenient and fast, and compared with the scheme of setting a signal receiving carpet on the runway, the runway is made barrier-free, and the problem that the signal receiving carpet affects the test accuracy due to fixing problems is also avoided.

[0041] It should be further noted that the value of the preset interval time mentioned above is 10 ms. Of course, the preset interval time can also be set to other values according to the situation. According to this preset time interval, the microwave sensor 1400 emits beacon frames. The value range of the specific power mentioned above is -18 dBm to 0 dBm. In this interval, the larger the power, the larger the coverage area. The appropriate coverage range can be selected according to the on-site situation. Preferably, the specific power can be set to -18 dBm, -12 dBm, -6 dBm, 0 dBm. The intensity and range of the finally emitted beacon frame can be adjusted according to the selection of different specific powers. The value range of the specific frequency mentioned above is 2401 MHz to 2499 MHz, including 99 channels such as 2401 MHz, 2402 MHz, 2403 MHz... 2499 MHz for selection.

[0042] Further, the shielding cavity 1310 has an open end 1330 and a closed end 1320 which are oppositely arranged. The microwave mobile sensor 1400 is arranged on one side close to the closed end 1320. The reflection track extends tortuously from the closed end 1320 to the open end 1330. The beacon frame is reflected and constrained along the reflection track and exits from the open end 1330 to the end area. The beacon frame is emitted by the microwave mobile sensor 1400 in the shielding cavity 1310. After being reflected by the shielding cavity 1310, the open end 1330 cannot constrain or reflect the beacon frame. Thus, the beacon frame in the shielding cavity 1310 is emitted from the open end 1330, which is more concentrated than the beacon frame emitted by the microwave mobile sensor 1400. Thus, the concentration and constraint of the beacon frame are realized. The beacon frame emitted from the open end 1330 can be used as an end mark (invisible) after the adjustment of intensity and position, and can be recognized and received by the signal receiving component 3000.

[0043] Further, the beacon frame has a plurality of microwave signal beams. After being reflected and constrained by the reflection track, the plurality of microwave signal beams form a conical microwave signal beam. The radial dimension of the conical microwave signal beam gradually increases along the direction from the closed end 1320 to the open end 1330.

[0044] Further, the shielding cover 1300 includes an upper plate body 1340, a lower plate body 1350, a front plate body 1360, a rear plate body 1370, and a side plate body 1380. The upper plate body 1340, the lower plate body 1350, the front plate body 1360, the rear plate body 1370, and the side plate body 1380 enclose to form the shielding cavity 1310 having a closed end 1320 and an open end 1330. The microwave motion sensor 1400 is disposed close to the side plate body 1380. The beacon frame is reflected and constrained by the upper plate body 1340, the lower plate body 1350, the front plate body 1360, the rear plate body 1370, and the side plate body 1380, and exits from the open end 1330 to a preset end area.

[0045] When selecting the shielding material for the shielding cover 1300, based on the general equation of existing reflection loss:

[0046]

[0047] where μ r represents the magnetic permeability of the shielding material, and σ r represents the conductivity of the shielding material. It can be seen from the above formula that the higher the conductivity and the lower the magnetic permeability of the shielding material, the greater the reflection loss. The shielding cover 1300 is made of a material with high magnetic permeability, which can reduce the reflection loss, so that most of the beacon frames can exit from the open end 1330, improving the intensity. Based on the high magnetic permeability of iron, preferably, iron is used as the shielding material.

[0048] Further, the shielding material in the present application is a single-layer structure.

[0049] To improve the stability of the setting of each component, a protective cover 1500 is further included. The protective cover 1500 is disposed in the installation cavity 1110, and the main control board assembly 1700 and the shielding cover 1300 are disposed in the cavity of the protective cover 1500.

[0050] Further, a part of the protective cover 1500 corresponding to the open end 1330 is provided with an exit window 1510, so that the beacon frame exits from the exit window 1510 to the end area.

[0051] Further, it further includes a control panel assembly 1600 and a battery assembly 1800. The installation cavity 1110 has an installation opening 1120. At a position corresponding to the installation opening 1120, the protective cover 1500 has an opening. The control panel assembly 1600 and the battery assembly 1800 are arranged in the cavity of the protective cover 1500. The control panel assembly 1600 is arranged at the opening of the protective cover 1500. The control panel assembly 1600 includes a control panel unit that realizes display and / or input functions. The control panel assembly 1600 is electrically connected to the microwave motion sensor 1400 to trigger and control the operation of the microwave motion sensor 1400 or trigger and adjust the intensity of the beacon frame of the microwave motion sensor 1400. The battery assembly 1800 is electrically connected to the microwave motion sensor 1400 to supply power to the microwave motion sensor 1400.

[0052] In practical applications, the control panel unit is a touch screen. Through the touch screen, the intensity of the beacon frame signal can be adjusted, that is, by selecting preset gears, such as four gears of -18dBm, -12dBm, -6dBm, and 0dBm, to emit an appropriate signal intensity. The corresponding signal intensity can also be selected by operating buttons to add or subtract specific power values.

[0053] Of course, the control panel unit can also include a display screen and operation buttons. The intensity gear is selected through the operation buttons, and the display screen can display the currently selected signal information and / or alternative signal information.

[0054] Further, it further includes a cover body 1200. The cover body 1200 is movably or detachably connected to the housing 1100 to open or close the installation opening.

[0055] Further, when the barrier-free middle and long-distance running finish test device is in use, it is generally placed on both sides of the runway finish, such as in the inner or outer circle of the runway. Generally, its placement environment is not limited to indoors, but also includes outdoors. When placed outdoors, external environmental conditions are likely to cause the barrier-free middle and long-distance running finish test device to shift (such as being blown by the wind or being touched by people). The battery assembly 1800 generally has a certain weight. Placing it close to the bottom can improve the placement stability and it is not easy to be knocked down or blown down, resulting in its displacement and affecting the test accuracy.

[0056] In one embodiment, the battery assembly 1800 includes a power module 1820 and a fixing module 1810. The fixing module 1810 is used to fix the power module 1820 in the cavity of the protective cover 1500 to prevent the power module 1820 from moving during the movement of the barrier-free middle and long-distance running finish test device, thereby damaging the internal electronic components and causing equipment damage.

[0057] In one embodiment, a counterweight module 1900 is further provided in the cavity of the protective cover 1500. The counterweight module 1900 includes at least two counterweight units, namely a first counterweight unit 1910 and a second counterweight unit 1920. The counterweight units are evenly arranged in the cavity of the protective cover 1500 to adjust the weight and stability of the end point testing device. By providing the counterweight module 1900, the weight of the entire barrier-free middle and long-distance running end point testing device can be increased to ensure that it will not be blown down or knocked down.

[0058] Furthermore, in order to reduce the overall weight, other components including the housing 1100, the cover 1200, etc. can be made of plastic materials. Since the shielding cover 1300 is made of iron, a plurality of small holes can be provided thereon to reduce its weight, thereby reducing the weight of the entire device.

[0059] It should be further noted that setting the counterweight module 1900 to increase the weight and setting small holes on the shielding cover 1300 to reduce the weight are not contradictory. The main function of the counterweight module 1900 is to increase the weight and balance at the bottom of the end point controller 1000. Therefore, multiple counterweight units need to be evenly placed to avoid the risk of the entire device being top-heavy or having uncoordinated left and right weights, thus being prone to tipping over.

[0060] Based on the use environment of the barrier-free middle and long-distance running end point testing device, its internal electronic components are easily damaged by external rainwater. The cover 1200 and the housing 1100 need to be hermetically connected to achieve waterproof treatment. A sealing strip 11000 is provided on the cover 1200 and / or the housing 1100 to ensure a seal is formed between the cover 1200 and the housing 1100.

[0061] To further illustrate the application scenarios and environment of the barrier-free middle and long-distance running test end point controller 1000, refer to Figure 4 , this application also provides a barrier-free middle and long-distance running test system, including the above-mentioned barrier-free middle and long-distance running test end point controller 1000, a signal receiving component 3000, and a test host 2000. The signal component is configured to be carried by an athlete. The signal receiving component 3000 is used to receive the beacon frame with a packet number transmitted by the end point controller 1000. The test host 2000 is respectively signal-connected to the end point controller 1000 and the signal receiving component 3000. The test host 2000 is used to record the time when the signal receiving component 3000 receives the beacon frame and the time and / or number of times when the intensity of the received beacon frame is the strongest.

[0062] In practical applications, the test host 2000, the end point controller 1000, and the signal receiving component 3000 communicate point-to-point. To further reduce runway obstacles, the test host 2000, the end point controller 1000, and the signal receiving component 3000 communicate through a wireless communication module. For the wireless communication module applied thereto, in one embodiment, a 2.4G wireless communication module can be adopted.

[0063] In an actual running race, since the test host 2000 processes the information of the intensity and time of the signals received by the signal receiving component 3000, the test host 2000 is set around the end area. To avoid interference between the end point controller 1000 and the test host 2000, the test host 2000 and the end point controller 1000 are set on the inner and outer sides of the runway. The signal receiving component 3000 is worn on the athlete and can be carried in the form of a bracelet or a card.

[0064] Based on the functions of the signal receiving component 3000 and the test host 2000, in other embodiments, the signal receiving component 3000 can also be improved so that it not only has the ability to receive signals but also can process information, that is, the function of recording the time when the signal receiving component 3000 receives the beacon frame and the time and / or number of times when the intensity of the received beacon frame is the strongest is set on the signal receiving component 3000, and the test host 2000 is only used to summarize this information and analyze the performance of the athlete.

[0065] To further illustrate the usage method of the end point controller 1000 for the barrier-free middle and long-distance running test, the present application also provides a barrier-free middle and long-distance running test method, and its steps include:

[0066] The end point controller 1000 transmits a beacon frame with a packet number at a specific power at a specific frequency within a preset interval time;

[0067] Reflect and constrain the beacon frame and transmit the beacon frame to a preset end area;

[0068] The signal receiving component 3000 receives the beacon frame and records the time and intensity of the beacon frame signal;

[0069] The test host 2000 obtains the time corresponding to the strongest intensity of the beacon frame signal based on the time and intensity of the beacon frame signal;

[0070] The test host 2000 determines the test result of the person to be tested based on the time corresponding to the strongest intensity of the obtained beacon frame signal.

[0071] Further, the test host 2000 can perform tests in a single-group test mode and a multi-group test mode;

[0072] In the single-group test mode, the signal receiving component 3000 receives the beacon frame and records the time and intensity of the single-group beacon frame signal; the test host 2000 determines the test score of the person to be tested based on the time corresponding to the strongest intensity of the obtained beacon frame signal.

[0073] In the multi-group test mode, the signal receiving component 3000 receives the beacon frame, records the time and intensity of the multi-group beacon frame signals, and obtains the number of times when the intensity of the beacon frame signal is the strongest; the test host 2000 determines whether the person to be tested has completed the test based on the number of times when the intensity of the obtained beacon frame signal is the strongest; the test host 2000 determines the test score of the person to be tested based on the time corresponding to the strongest intensity of the last obtained beacon frame signal.

[0074] In Figure 4 In the case of the shown running route, the starting point (the solid line a is the starting line) and the ending point (the dashed line b is the ending line) are set in different places, and the end controller 1000 is set at the preset end area. The athlete starts running from the starting point. Before running, information is entered at the test host 2000, such as corresponding the athlete's name, number, etc. with the number of the signal receiving component 3000. One signal receiving component 3000 with a number corresponds to one athlete. The time when the signal receiving component 3000 receives the beacon frame can be used as the score of this athlete. Specifically, since the beacon frame presents a conical structure at the preset end area, such as Figure 4 the dashed area in and when the signal receiving component 3000 approaches and leaves the preset end area, the received signal has a process of changing from weak to strong and then from strong to weak. Therefore, selecting the moment when the signal is the strongest as the test score corresponding to the athlete can improve the accuracy of the test. At this time, the single-group test mode can be selected.

[0075] If the preset running route is on a circular track, the athlete may need to pass through the end area multiple times during a training test. Therefore, the multi-group test mode can be selected. Whether the athlete has completed the running route of the preset number of laps is determined by the number of times the athlete passes through the end area. The time when the athlete corresponding to the completed preset number of laps passes through the end area for the last time is the test score of this athlete.

[0076] Furthermore, if it is necessary to analyze the running situation of a certain athlete during the entire exercise process, such as comparing the running speed of each lap, it can also be obtained by comparing the time when passing through the end area in the previous lap and the time when passing through the end area in the next lap.

[0077] It should be further noted that the time when the above-mentioned athlete passes through the end area is based on the time corresponding to the strongest received signal.

[0078] Further, since there are generally multiple athletes participating in the exercise test simultaneously during the exercise test, the corresponding signal receiving components 3000 will have different numbers for different athletes. When an athlete receives the test, the signal receiving component 3000 (a wearable device with the signal receiving component 3000, such as a tag card, a bracelet, etc.) that he / she needs to carry is used to enter information at the test host 2000. When the athlete is being tested, the test host 2000 can record and analyze the results of the corresponding athlete according to the entered information.

[0079] Further, the above-mentioned single-group test mode and multi-group test mode can be switched manually. For example, two selection modules are preset on the test host 2000, one corresponding to the single-group test mode and the other to the multi-group test mode. During use, it can be selected according to the runway conditions. Of course, it can also be automatically switched by the test host 2000 based on the number of times the signal receiving component 3000 receives a signal (that is, the athlete enters the finish area). For example, when the test host 2000 detects that the signal receiving component 3000 has received a signal twice, it automatically switches to the multi-group test mode. When calculating the results, it is automatically calculated in the manner of the multi-group test mode, that is, the test host 2000 determines whether the tested person has completed the test based on the number of times the intensity of the obtained beacon frame signal is the strongest; the test host 2000 determines the test results of the tested person based on the time corresponding to when the intensity of the beacon frame signal is the strongest for the last time.

[0080] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention pertains, based on the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
