The Knowledge Structure Required for Repairing Simulators
Entering the world of simulators, before you lies a cluster of technological peaks. I can assert that no one can completely conquer them. You may take a look at the knowledge required:
1. Digital Circuit Knowledge: Lottery machine motherboards generally use 51 series microcontroller technology, while token pusher machine motherboards are much more complex with many manufacturer-specific chips. In addition, there are signal detection boards, motor drive boards, solenoid drive boards, operation control boards, digital tube drive boards. Racing and gun machines also have analog-to-digital conversion, digital-to-analog conversion, and photoelectric conversion.
2. Analog Circuit Knowledge: Switching power supplies, low and high resolution scanning, rear projection display, LCD display. Some scans, like the first three, are bus-type.
3. Sensor Knowledge: Beer barrels use Hall elements, Drum King and Jazz Drums have vibration sensors!
4. Computer Knowledge: Many racing and music machines use computer hosts, mostly Linux systems, with various encryption technologies employed.
5. Electro-Mechanical Knowledge: Most simulators have various mechanical transmission devices. For example, racing steering wheels and vibration feedback devices, token pushers' coin channels and push plates. Almost all lottery machines have mechanical components. There are various motors: AC motors, DC motors (these AC/DC motors usually have gear reduction devices). Large gift machines and mining vehicles also use stepper motors.
Isn't every single one of these something that takes a lifetime to learn? I think we only have a few strategies:
First, focus on on-site maintenance, try to learn a little bit in all areas. Be able to understand the mechanical and circuit structures of various machines, accurately determine the location of faults, and perform board-level repairs. Leave deeper chip-level repairs to others.
Second, conduct in-depth research in one area, mastering advanced technology for several types of machines. This would be chip-level.
Third, master a core technology and become a development-oriented talent.
