Computer monitoring and testing of automatic control system

摘要

A computer system tests and monitors a pneumatic control system designed to automatically control steam boilers. Transducers are provided which measure the pneumatic pressures in the pneumatic control system as well as some of the parameters in the boiler system itself. These transducers convert the sensed values to digital values and can be read by a computer every tenth of a second. The computer operates and is controlled by a touch sensitive display and is programmed to provide directions on the screen to lead an operator through each of the series of the series of test steps necessary to evaluate the various components of the pneumatic control system. In addition, the system continuously monitors the various parameters of the system and through control of the touch sensitive display, the operator can have displayed to him the various parameters of the system. In addition, the system is operable to continuously monitor the sensed parameters of the system to determine whether any of the sensed parameters values are outside of specification values and to indicate to the operator which parameters are at fault. In addition, the operator through the system of the invention can select and be lead through a flex test for the boiler. In this test, all of the parameters are read at one tenth of a second intervals and can be compared in a statistical analysis against a mathematical model to obtain a figure of merit for the operation of the major components of the pneumatic control system.
