Analysis of the electromechanical integration principle of the shooting machine in the arcade
1、 Coin Identification System: Electromagnetic Induction and Signal Comparison
The coin insertion system of the shooting machine uses electromagnetic induction technology to achieve coin identification. When a coin passes through the coin slot, the built-in oscillating wire package will produce resonant frequency changes due to differences in coin material and size. The voltage signal generated by coil induction is sent to an operational amplifier (such as the 4558 chip mentioned in the document) for amplification and comparison. After matching with the preset "standard coin" parameters (weight, diameter, material, etc.), the CPU will trigger the unlock signal.
During this process, the photodetector synchronously monitors the movement trajectory of the coin to prevent foreign object interference; The electromagnetic channel switch briefly opens after successful verification, allowing coins to enter the coin storage box. If the coins do not match, the mechanical lock will remain locked to ensure the safety of the equipment.
2、 Game startup mechanism: Control logic of electromechanical linkage
After successful coin insertion, the CPU sends a startup command to the main control board, triggering the following chain reaction:
Electromagnetic lock release: Unlock the shooting machine start switch and activate the timing module
Power system energized: Basketball lifting device begins to cycle and supply balls
Display system initialization: LED screen starts countdown and resets score
It is worth noting that some high-end models have adopted gallium nitride power technology, whose high-efficiency conversion characteristics can reduce the power consumption of electromagnetic locks and motors, and extend the continuous operation time of equipment.
3、 Shooting detection technology: photoelectric sensing and dynamic capture
The core detection system of the shooting machine includes dual feedback:
Infrared array detection: Multiple sets of infrared sensors are arranged on the inner wall of the basketball hoop, and the counting signal is triggered when the basketball passes by and blocks the light beam
Pressure sensing assistance (advanced model): A micro switch is installed at the bottom of the basket to double verify the basket entry action and prevent misjudgment
The detection signal is transmitted to the main control board after analog-to-digital conversion, and the CPU processes the data in real time and drives the following feedback:
Points display: 7-segment digital tube or LED screen dynamically updates scores
Sound and light interaction: customized sound effects through JBL, combined with flashing lights to enhance immersion
Reward mechanism: Continuous hits trigger special animations, and some models are linked to coin vending machines to distribute physical prizes
4、 Technological Evolution Trends
The current new shooting machine is showing three major upgrade directions:
Energy efficiency optimization: using three color laser projection instead of traditional backlight screen, reducing power consumption by 40%
Interactive upgrade: Integrated IMAX Enhanced certified immersive audio and video system
Intelligent Expansion: Remote Maintenance and Data Collection through IoT Modules
This article combines the principles of mechanics and entertainment needs to reveal how shooting machines can transform simple shooting movements into fun interactive experiences through precise technological integration. With the development of laser projection and intelligent sensing technology, future gaming devices will create more disruptive entertainment scenes
