| Abstract: | Boiler control system at Chengbei-B platform is a complex logical control system, which is controlled by a program controller drove by a step-motor and composed by general purpose relays, timing relays, temperature switches, pressure switches, limit switches and some other protection elements. Since it has been used for more than fifteen years, the system usually appeared some faults such as could not start up normally, automatically stop without any fault report, the program control system based on industrial computer and the logic is realized by internal programming language. The reliability and diagnosis of the PLC system are improved effectively. After the boiler control system is improved by means of a PLC system, the faults are solved absolutely. . |
