Description
Technical Field
[0001] The utility model relates to the field of pitching scoring devices, in particular to a projection device capable of detecting hollow-shot balls. Background Art
[0002] Generally speaking, the judgment of hollow goals on shooting machines in the gaming industry has always troubled people. Now, people usually do not make judgments, which reduces the fun of the game and the accuracy level of the shooting cannot be reflected. It is impossible to distinguish between hollow goals that are more difficult to achieve and rebound goals that are easier to achieve. As a result, the technical gap between various goals cannot be reflected in the score. There is only a single indicator of the number of goals scored, which limits the possibility of showing the results after the goal is scored. Furthermore, it is impossible to attract users with good skills to play, which reduces the appeal.
[0003] Therefore, a ball pitching result detection device is needed that can effectively distinguish whether a ball pitched into the frame is a hollow ball that directly penetrates. Utility Model Content
[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a pitching result detection device which can effectively distinguish whether a ball pitched into a frame is a hollow ball that directly penetrates through it.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] A projection device capable of detecting hollow balls includes a base, a drop-in frame is arranged on the base, and a ball sensor arranged facing the drop-in frame is also arranged on the base; a vibration sensor for sensing whether the drop-in frame is vibrating is also arranged on the drop-in frame / base; the base is also provided with a judgment module, and the judgment module is connected to the ball sensor and the vibration sensor signal.
[0007] By adopting the above technical solution, the goal sensor is responsible for sensing whether a ball passes through the input frame, that is, whether a goal is scored. The vibration sensor set on the input frame / base is responsible for sensing whether the input frame and base and other structures such as the backboard are moved by the ball. The judgment module outputs the result after analyzing the signal of the goal sensor and the signal of the vibration sensor. If there is no signal from the goal sensor, there is no goal; if there is a signal from the goal sensor and the vibration sensor, it is judged as a non-hollow goal; if there is a signal from the goal sensor and no signal from the vibration sensor, it is judged as a hollow goal.
[0008] As an improved solution, the vibration sensor includes a balance bar connected to the input frame / base, and the balance bar is transmission-connected to the input frame / base. The vibration sensor also includes a ranging infrared sensor arranged facing the balance bar, and the ranging infrared sensor is signal-connected to the judgment module.
[0009] By adopting the above technical solution, as long as the shot frame, the base and other structures such as the backboard are hit by the ball, the balance bar will be driven to swing, and the balance bar will have the effect of amplifying the vibration amplitude for easy detection. The ranging infrared sensor detects the vibration of the balance bar and sends a signal to the judgment module, so that the judgment module determines that it is a non-hollow goal.
[0010] As an improved solution, the balance pole is hinged on a balance bracket, the balance bracket is fixedly connected to the input frame / base, the balance pole can swing on the balance bracket, and the ranging infrared sensor is arranged facing the swinging direction of the balance pole.
[0011] By adopting the above technical solution, the upper part of the balance bar is hinged to the balance bracket, and the lower part of the balance bar swings freely. When the input frame / base connected to the upper part by the balance bracket is impacted and vibrated, the lower part of the balance bar swings, increasing the vibration amplitude. The greater the distance from the hinge point of the balance bar to the lower part, the more obvious the amplification of the vibration amplitude.
[0012] As an improved solution, the ball sensor is a diffuse reflection type photoelectric switch, and the diffuse reflection type photoelectric switch is arranged perpendicular to the ball outlet path of the input frame.
[0013] By adopting the above technical solution, it can be ensured that a signal is sent out to judge a goal only when the ball passes through the ball outlet path, and the reliability is high.
[0014] As an improved solution, a shock-absorbing damping member is provided at the bottom of the base, and the base is connected to the wall / support frame via the shock-absorbing damping member.
[0015] By adopting the above technical solution and using shock-absorbing damping parts, the vibration sensor can be prevented from being disturbed by the wall / basketball stand on which the base is installed or other external vibrations, thereby avoiding the situation where hollow goals are misjudged as non-hollow goals, thereby improving the accuracy and reliability of detection.
[0016] As an improved solution, a first distance measuring sensor for detecting the distance of the shooter relative to the shooting frame is provided on the base, and the first distance measuring sensor is connected to the judgment module signal.
[0017] By adopting the above technical solution, the distance between the pitcher and the pitching box can be detected, so that a new data of the pitching distance can be introduced when scoring or recording, thereby further subdividing the scoring criteria and improving the display effect of the results.
[0018] As an improved solution, a second distance measuring sensor for detecting the shooting action of the shooter is provided on the base, and the second distance measuring sensor is connected to the judgment module signal.
[0019] Specifically, the second distance measuring sensor is arranged facing an area with a higher detection height than that of the first distance measuring sensor.
[0020] By adopting the above technical solution, when there are multiple pitchers in the pitching field, it is possible to measure which pitcher has raised his hand to pitch based on the signal of the second ranging sensor. For the judgment module, the pitcher whose second ranging sensor is at the same distance as the first ranging sensor is selected for judgment and scoring.
[0021] As an improved solution, it also includes a solar panel and a battery, and the battery is electrically connected to the solar panel and the judgment module respectively.
[0022] By adopting the above technical solution, the basketball stand set up in the open air venue can be charged by solar energy and use batteries to store electrical energy, so it can work without the need to pull and clamp additional wires. On the one hand, it saves the cost of site circuit construction, and on the other hand, it avoids the safety risk of wire damage and leakage in extreme windy and rainy weather.
[0023] As an improved solution, a sleep module and a sound receiving sensor are provided on the base, and the sleep module is respectively connected to the sound receiving sensor and the judgment module by signals.
[0024] By adopting the above technical solution, by sensing the surrounding volume, it is possible to set the device to sleep when the surrounding volume is continuously below a certain range, stop operating in the quiet night, and save power. On the other hand, it is also possible to set the device to sleep when the surrounding volume is above a certain range, and stop operating in extreme windy and rainy weather or when there is a large construction site nearby, etc., where the noise is too loud and covers the score broadcast, to save power.
[0025] As an improved solution, a speaker and / or a light emitting element is provided on the base, and the speaker and / or the light emitting element is signal-connected to the judgment module.
[0026] By adopting the above technical solution, the pitching results and scores can be broadcasted and announced in real time through the light-emitting board / scoreboard / display screen.
[0027] Compared with the prior art, the beneficial effects of the utility model are:
[0028] The goal sensor is responsible for sensing whether the ball has passed through the input frame, that is, whether a goal has been scored. The vibration sensor set on the input frame / base is responsible for sensing whether the input frame and base and other structures such as the backboard are moved by the ball. The judgment module outputs the result after analyzing the signal of the goal sensor and the signal of the vibration sensor. If there is no signal from the goal sensor, there is no goal; if there is a signal from the goal sensor and the vibration sensor, it is judged as a non-hollow goal; if there is a signal from the goal sensor and no signal from the vibration sensor, it is judged as a hollow goal.
