According to reports, a few days ago the Municipal Education Bureau issued a document requesting all primary and secondary schools and kindergartens to install electronic eyes to implement full monitoring of all aspects of the canteen procurement and processing to prevent the occurrence of catering safety accidents. Although such a starting point is good, this approach still raises many questions. Electronic eyes are installed in all primary and secondary schools in the city. How much does it cost? No matter who comes out of this money, it will eventually be the taxpayer's money, not to mention how much it can play or a big question mark. Just a few years ago, when school bus safety accidents occurred frequently, the school bus was installed with electronic tracking and monitoring equipment. It also cost a lot of money, but what is the effect, how many school buses are still in normal use today, do all the Education Bureau know? If the Education Bureau has not fully understood it, or if the actual effect of this technical means is average, then such documents should not be hurriedly released, nor should such expensive technical projects be forced. Besides, in order to monitor in time and not to miss the clues, schools must also appoint a special person to be in front of the electronic screen, and they must not be careless for a moment, otherwise a little negligence, raw rice cooked mature rice, it is likely to cause facts, and still cause serious The consequences are equivalent to no effect. In fact, in recent years, in order to strengthen campus safety, various schools have set up so-called security offices, equipped with security personnel such as fire protection, network monitoring, and campus inspections. . The most fundamental problem is that the educational administration is used to issuing documents in case of accidents or relying on technological thinking to solve problems. However, past experience and lessons have repeatedly told us that such a solution to the symptoms and the root cause will not last for a while. For several years, when I looked back at the measures and methods that were introduced at the beginning, I discovered that the original decision was wrong. It not only failed to solve the problem, but also caused huge waste. After all, the electronic eye cannot replace the human eye. USB 3.0 is the future and the new generation in transmission tech, with the following advantages: Super speed – It`s 10 times faster than its predecessor and backward compatible with all USB 2.0 interfaces. It uses a 9-pin connector with 4 pins compatible with USB 2.0 and another 5 pins for bi-directional data transfer.
