At present, there are two kinds of multimedia safety toolboxes for construction site employees on the market.
One is a big box based on Wuhan Bosheng, which contains hardware such as keyboard and answering machine. Generally, a set is about 4w-5w.
There is also a relatively new multimedia safety training mat, represented by Nanjing bronze building clothes, which is a combination of software and hardware. There are all kinds of training courseware in it. The exam is mainly a code scanning exam, and everyone doesn't need to use hardware such as an answering machine, so the size that can be made is very small, only the size of a notepad, generally about 2 W.
