Alas, have you ever seen a kind of glowing dance floor when you watch short videos? It is a cool floor tiles screen that will change patterns according to the rhythm when people step on it. Now even wedding companies are starting to play this, but novices want to learn this craft, and nine out of ten will be cheated - some spend 30,000 yuan to sign up for training classes, but they all teach old techniques from five years ago; some go to factories to be apprentices, and they don’t have the chance to touch core technologies by twisting screws all day long. Today I broke the tricks here and said, "I will definitely save you from detours for three years."

1. All serious skills are in the workshop

Last year, I met a young man who was having a wedding and spent 28,000 yuan to sign up for a master class. After graduation, I found out that I was learning the straight screen installation set.​​For real floor tile screen technology, you must master these hard-core knowledge points​​：

1. ​​Waterproof structure disassembly​: You have to know how to spray the nanocoat under the 6mm tempered glass, and how to design the angle of water splashing during rainy performances
2. ​Pressure sensing calibration​: The grading of the force of a person stepping on must be divided into at least 16 levels, otherwise the special effects will not keep up with the rhythm when dancing.
3. ​​Heat dissipation air duct design​: The stupidest case I have ever seen, the apprentice installed the cooling hole upwards, but it turned out that it was raining and it was soaking three screens.

It is recommended to directly find an internship company with an automation workshop. It is more effective than watching 100-hour online courses. 60% of the installation problems in the industry are actually because they do not understand the structural principles thoroughly.

2. Don't be fooled by these training institutions

Last month, I accompanied my friend to listen to the training class, and the teacher was still teaching the parameters of the P10 floor tiling screen - who is using such rough pixels these days!​​Selecting a training institution requires three practical indicators​​：

• ​Device update speed​: Still using the direct pass of the 2018 control system
• ​​Fault simulation training​: Can you get access to real cases, such as screen repair caused by signal interference
• ​Industry connection resources​: Can you join the installation team and project after graduation? Just having a certificate but not doing it is equivalent to waste paper

There is a ruthless trick: I ask to disassemble and assemble the box by myself when listening. Only institutions that can complete module replacement within ten minutes are reliable, and those who only want to view PPTs to block them as soon as possible.

3. Three essential tools for self-study party

I met a township electrician and used these three tools to chew the floor tiles and screen technology:

1. ​Second-hand control card​: A fish has a 500-yuan reception card, and I swiped the firmware myself to complete the signal debugging
2. ​3D simulation software​: You can practice splicing without using a real screen, and you can also simulate extreme scenes such as rainy days/high temperatures
3. ​Industry Technology White Paper​: The latest version of "LED Floor Tile Screen System Integration Specification" contains more than 30 practical parameters

This guy is now receiving wedding installation orders, and the fee per square meter is 200 yuan higher than that of a professional. To put it bluntly, this industry recognizes craftsmanship but not diplomas. It is the real ability to solve emergencies on the spot.

4. The unspoken rules that veteran drivers won't tell you

Once when I was drinking with the installation team, he revealed an inside story in the industry: In fact, 35% of floor tiles and screen failures are caused by improper debugging and are not hardware problems at all.​​Practical skills that these schools do not teach​​：

• Before paving, use a laser level to tap the grid line. The error exceeds 2mm will affect the touch accuracy.
• The splicing seams should be left with "living mouths". Areas with large temperature differences should be buried with telescopic aluminum strips.
• Play solid color dynamic pictures first during debugging, which is the easiest way to discover the attenuation problem of lamp beads
• The most ruthless one is here - use the electronic scale bought in the supermarket to measure the load bearing uniformity of each screen

Another trick: using the "Rhythm Lightsaber" game as a test program, it can simultaneously check the touch response speed and image delay, which is ten times more reliable than the manufacturer's own detection program.

Some training classes now boast about teaching "holographic floor tiling screen technology", which is actually adding layers of acrylic boards to ordinary screens. True cutting-edge technologies such as pressure-light-shadow linkage algorithms and AI action prediction and compensation have to go to companies with R&D centers to steal their skills. The most outrageous case I have ever seen, someone spent 50,000 yuan to learn the "meta-cosmic floor tiles screen", but found that it was an ordinary interactive program installed.

Don’t be superstitious about certificates when studying in this industry. Those who have swung wrenches on the construction site are more popular than those who get higher scores in the exam. Next time you go to the consultation and training, and ask directly: "Can I disassemble and assemble the repaired parts with faults?" - Those who dare to let you do it are the real ability. Remember, the floor tile screen technology is updated faster than that of mobile phones. The arc splicing technology learned last year may have been eliminated by flexible modules this year. Maintaining hands-on habits is better than any training.
