[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See Figures 1-6 This utility model provides a technical solution: a flexibly deployable soccer shot detection device, including a main control MCU, which is connected to a left sensing area 3 and a right sensing area 4; the left sensing area 3 includes a transmission drive circuit and an infrared emitting tube, and the right sensing area 4 includes a receiving conditioning circuit and an infrared receiving tube; the transmission drive circuit is connected to the infrared emitting tube; the infrared detection line emitted by the infrared emitting tube illuminates the infrared receiving tube along the light path; the infrared receiving tube is connected to the receiving conditioning circuit; the infrared emitting tube and the infrared receiving tube are installed on the side of the soccer goal frame near the inside of the goal and at a preset distance from the soccer goal frame; the soccer goal frame is provided with an anti-torsion structure 7 for setting the deployment angle of the left sensing area 3 and the right sensing area 4.

[0028] In this embodiment, to adapt to different goals, the main control MCU records the position of the already obscured sensing area upon power-on. In subsequent tests, only the obscured sensing area at power-on is checked to determine if a ball has been shot. The infrared detection line is positioned 11cm (the radius of a standard size 5 soccer ball) from the goalpost's centerline, ensuring no missed detections and reducing false detections caused by the soccer ball hitting the goal frame and bouncing out. This distance is pre-set by the structural component (mounting sheet metal bracket 6) using straps, making installation simple.

[0029] The anti-torsional structure 7 ensures that the infrared emitting tube and infrared receiving tube do not undergo horizontal torsion (e.g., Figure 5 As shown, the deployment angle of the left and right sensing areas is set by the angle between the reinforcing rod at the rear of the goal and the fixed angle at the front. No alignment adjustment is required after installation.

[0030] In some embodiments, a bracket is installed between the left sensing area 3 and the right sensing area 4 and the football goal frame.

[0031] In some embodiments, the bracket is a sheet metal bracket 6.

[0032] In some embodiments, the preset distance is 11cm.

[0033] In some embodiments, multiple wide Velcro straps 8 are installed on the football goal frame to fix the left sensing area 3 and the right sensing area 4.

[0034] In this embodiment, as Figure 6As shown, three 5cm wide magic straps are tied to the goalpost, which can effectively reduce the impact and vibration of the football shot, improve the stability of the device, and make it reliable in strength while being very convenient to deploy and disassemble.

[0035] In some embodiments, the main control MCU is also connected to a buzzer.

[0036] In some embodiments, the main control MCU is also connected to a communication module.

[0037] In some embodiments, the communication module is a 433M wireless module.

[0038] In this embodiment, a wired connection is used between the infrared transmitter and receiver to improve scanning speed and stability. The device uses 433M wireless communication to interconnect with the system central unit, improving deployment flexibility.

[0039] In some embodiments, the main control MCU is also connected to a power supply module.

[0040] In some embodiments, the power supply module includes a power management module and an input power supply, wherein the input power supply is connected to the input terminal of the power management module, and the output terminal of the power management module is connected to the main control MCU.
