Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of volleyball monitoring, and in particular relates to an intelligent auxiliary monitoring device for volleyball. Background Art
[0002] Volleyball is a popular ball sport, and the volleyball pass assessment is a test item used to evaluate the basic skills of volleyball players. Passing is a basic action in volleyball and an important part of passing in team games.
[0003] There are many ways to assess the ball-passing, such as two-person ball-passing or single-person ball-passing. For single-person ball-passing, the ball-passing against the wall is often used. During the assessment, a suitable venue for ball-passing against the wall is selected, such as a volleyball court or the wall of a gymnasium, and a suitable target area is marked on the wall. The athlete stands at a suitable distance from the wall and prepares to perform the wall-passing. An assessment administrator or coach stands opposite the athlete with the ball and serves the ball to the athlete with his hand or a serve. The athlete uses both hands to pass the ball against the wall. The goal of the pass is to accurately pass the ball into the marked area. The athlete can control the landing point of the ball by adjusting the strength and direction of the pass.
[0004] During the assessment process, the number of passes made by athletes and the number of successful passes are manually counted by the assessment administrator, which can easily lead to errors in the counting of the number of passes. At the same time, the accuracy of judging whether the pass is successful is low, which in turn leads to inaccurate scores for the assessors. Secondly, the efficiency of manual counting is also relatively low. Utility Model Content

For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0036] Among them, the assessment timing module is electrically connected to the main control module 1 for timing the assessment time; the biometric recognition module 2 is electrically connected to the main control module 1 for collecting the user's identity information and sending the identity information to the main control module 1; the volleyball sensing module is electrically connected to the main control module 1 for collecting the user's ball-passing signal in real time and sending the user's ball-passing signal to the main control module 1. The main control module 1 receives the ball-passing signal and counts the number of times the user passes the ball within the assessment time.
[0037] In this embodiment, the volleyball sensing module is arranged in the assessment area, and the biometric information of the person to be assessed is pre-stored in the biometric module 2; the biometric module 2 of this embodiment can be a fingerprint recognition module, an iris recognition module or an AI camera; the biometric module 2 of this embodiment preferably uses an AI camera, and the facial information of each person to be assessed is stored on the AI camera; the main control module 1 can use a microcontroller such as a single-chip microcomputer of the STM32 series.
[0038] During the assessment process, when the assessor enters the assessment area, the AI camera can identify the assessor's identity information from a distance, and then the assessment timing module starts timing the assessment time, prompting the assessor
[0039] After the assessment begins, the assessee starts to pass the ball, and the volleyball sensing module can collect the assessee's pass signal, that is, when the assessee passes the ball against the wall once, the volleyball sensing module can detect a pass signal and send the pass signal to the main control module 1. After the assessment time is reached, the collection is stopped; the main control module 1 counts the number of times the assessee passes the ball based on the received pass signals.
[0040] The monitoring device of this embodiment identifies the identity information of the examinee through the biometric module 2, and then performs the pass, which can avoid the problem of mismatch between the pass assessment result and the person; and in the assessment process, the volleyball sensing module automatically senses the pass signal of the examinee, and then the main control module 1 counts the number of passes, which can avoid manual counting errors and has a high accuracy rate; automatic statistics throughout the process can improve the efficiency of the assessment; secondly, the assessment timing module automatically generates the assessment time, and the volleyball sensing module only collects the pass signal within the assessment time, which can further improve the accuracy of the assessment result.
[0041] As a further optimization of this embodiment, Figure 2 As shown, the volleyball sensing module includes: a frame 3 and a detection sensor;
[0042] The detection sensor includes at least two groups of infrared detection units, each group of infrared detection units includes: an infrared transmitter 4 and an infrared receiver 5, the infrared transmitter 4 and the infrared receiver 5 are respectively detachably connected to two opposite arms of the frame 3, and the frame 3 is a volleyball sensing area; the infrared transmitter 4 and the infrared receiver 5 are both electrically connected to the main control module 1.
[0043] In this embodiment, the frame 3 can be arranged in any area, such as on the wall of a gymnasium, on the wall of a volleyball court, etc. The infrared transmitter 4 and the infrared receiver 5 of each group of infrared detection units are respectively arranged on the left and right sides of the frame 3, or on the upper and lower sides of the frame 3; when the examiner blocks the ball, the volleyball is blocked in the volleyball sensing area, and the infrared light emitted by the infrared transmitter 4 is blocked by the volleyball, which can be used as a ball blocking signal; the infrared transmitter 4 of this embodiment emits a laser, and the infrared receiver 5 receives the laser. The infrared receiver 5 is essentially a photoresistor; when the laser is irradiated on the photoresistor, the photoresistor is subjected to strong light and its resistance decreases; when the volleyball hits the wall, it blocks the laser, and the resistance of the receiver increases. By changing the resistance of the receiver, it can be determined whether the volleyball hits the effective area of the wall, thereby counting.
[0044] In this embodiment, eight groups of infrared detection units are preferably arranged on the frame 3. After the volleyball contacts the wall, in order to make the volleyball necessarily block the infrared light emitted by one group of infrared detection units, the spacing between two adjacent groups of infrared detection units is smaller than the radius of the volleyball. For example, the diameter of a volleyball is usually 21 cm, and the spacing between two adjacent groups of infrared detection units is set to 8 cm, or even lower. However, the lower the spacing, the more infrared detection units are required, and the higher the cost; in actual applications, the number of infrared detection units can be determined based on multiple tests.

[0048] The assessment end indicator light 8 is electrically connected to the main control module 1 and is used to light up when the assessment ends to remind the user that the assessment is over.
[0049] In this embodiment, the assessment start indicator light 7 uses a green LED light, and the assessment end indicator light 8 uses a red LED light. When the green LED light is on, the timing starts; the assessment time is 40s, and after 40s, the red LED light is on and the timing ends.
[0050] As a further optimization of this embodiment, Figure 3 As shown, the device also includes: an Internet of Things module 9, a display module 10 and a buzzer 11.
[0051] Among them, the Internet of Things module 9 is electrically connected to the main control module 1, and the Internet of Things module 9 is used to communicate with the remote Internet of Things platform. The assessment information corresponding to each assessor (identity information and corresponding assessment pass times) is uploaded to the remote Internet of Things platform through the Internet of Things module 9 and stored on the remote Internet of Things platform; the invigilator can use a computer or mobile phone to log in to the Internet of Things platform to view the assessment information of each assessor.
