　　Many manufacturers who make revolving doors see that some peers have made quick access doors, and the market is objective, so they follow suit and squeeze into the quick access door product market like dumplings. But they don't know that the difference between the two is quite big.

　　In comparison, the technical requirements of the revolving door are relatively simple, while the technical requirements of the quick pass door are much more complex than those of the revolving door (some people will certainly object to this view because the standards for the technical requirements of the products are different).

　　The similarities between the revolving door and the quick access door technology are: both operate because the pedestrian triggers the starting condition; Stop when running to a certain position; Moreover, it is necessary to realize the protection of pedestrians; Both need to deal with the logical relationship between the position sensor and the protection sensor signal.

　　However, there are great differences between them, which depend on the different functional requirements of users. The function of revolving door is to realize people's access unconditionally and isolate the internal and external environment; The function of speed gate is to realize people's passage conditionally (there are requirements for authorization, number of people passing, running direction and passing direction). The technology of unconditionally realizing people's passing through the revolving door has several characteristics: A. large running space; B. no specific requirements for the number of people passing; C. no requirements for the running direction and passing direction; d. There is no need to count the number of people entering and leaving. The control algorithm required by these characteristics is relatively simple and is used to control the rotation The gate program only needs hundreds of bytes.

　　The technical requirements are greatly improved due to the conditional access of the quick access door: A. small operation space; b. There are specific requirements for the number of people passing (one card and one person); C. requirements for the running direction and passing direction (the running direction must be consistent with the allowable passing direction); d. It is necessary to accurately count the number of people in and out. Because of these characteristics, the logic algorithm of the speed gate is much more complex than that of the rotary gate. The code used to control the speed gate is hundreds or even thousands of times of the program capacity of the rotary gate.

　　At present, in terms of quick access door technology, the military shield door industry is still at the forefront of the industry. It has made a major breakthrough in dealing with arm swing and anti tail follow-up technology, and the design is more humanized, which is the characteristic of the quick access door of the military shield door industry.
