【正文】 n 30%, the direct benefits of reduced installation costs, customers from booking to use lift cycle cost reduce the ladder and improve cash flow rate. B on the elevator using Bluetooth technology will make the elevator control system using a large amount of the latest and fastest puter, which will further improve the elevator machine reliability, fault rate is greatly reduced, the control precision is further increased, the result is the elevator more fortable, more accurate flat layer. C is a good solution to the elevator control and peripherals patible and contact. In particular can take the elevator and escalator induction to the building management system or intelligent management district system. The definition of PLC Programmable controller is a digital electronic puters operating system, specifically designed for applications in industrial environments designed. It adopts a kind of programmable memory, for its internal storage procedures, the implementation of logical, sequential control, timing, counting and arithmetic operations such as useroriented instructions, and through digital or analog input / output control various types of machinery or production process. Programmable controller and related peripherals, according to the easy and industrial control systems into a whole, easy to expand its function principle design. In short, the programmable controller is a puter, it is designed for industrial applications and the design and manufacture of puter. It has a rich input / output interface, and has strong driving ability. But the programmable controller products are not directed to a specific industry application, in practical application, its hardware according to actual need optional configuration, the software according to the control requirements for the design and preparation of. The characteristics of PLC: One, high reliability, strong antiinterference ability and high reliability is the key performance of electrical control equipment PLC due to the use of modern largescale integrated circuit technology, strict production process, the internal circuit adopts advanced anti interference technology, has very high reliability. Such as the Mitsubishi F series produced by PLC MTBF is high up to 300000 hours. Some use of redundant CPU PLC MTTF mean time to failure is longer. From the PLC machine circuit, the use of PLC control system, and the same scale relay systems, electrical wiring and switch contacts have been reduced to hundreds or even thousands of fault, also reduced greatly. In addition, PLC with hardware fault self testing function, failure can be timely warning information. In the application software, applications can also be incorporated into the peripheral device fault diagnosis program in the system, except PLC circuit and equipment were also obtained self diagnosis of fault protection. Thus, the entire system with high reliability is also not surprising. Two, matching plete, perfect function Applicability of PLC development today, has formed a large, small scale, in various series of products. Can be used for various scale industrial control occasions. In addition to the logic processing function, modern PLC mostly with plete data operation ability, can be used for various digital
