| Abstract: | Elevating fire engine,as the major high-end equipment for high-rise building fire rescue,has potentials for high security and high reliability.According to EU’s mechanical and electrical safety standard ISO13849-1,its safety performance rating is specified at the highest level.Through introduction of redundancy safety design in the input,output,communication and operation of the entire electrical control system of the fire engine and design of a redundancy safety control system based on safety PLC,we realize intelligent self-diagnosis of faults and quick response within the system,which,compared with the conventional electrical control system, features a much improved t safety and reliability. |
