Design of control system for steady state combustion fogger based on IEEE1451.4

In order to implement the automation and networking of the steady state combustion fogger,a smart transducer standard IEEE1451.4 was introduced in this paper to its control system of fogger for improving the degree of intelligence,and a systemic scheme of the intelligent control system with MMI and NCAP was put forward.By testing the relationship between temperature of the axis of nozzle mouth and burning time,as well as that between temperature of the axis of nozzle mouth and liquid flow,the appropriate delay time was obtained,based on which and the operating principles of the fogger the workflow of control system was designed.Furthermore,a "plugplay" thermocouple sensor was implemented by improving the traditional sensor through 1-wire digital interface and by the way of automatic calibration method.Therefore,the thermocouple sensor was capable of connecting with control system seamlessly.Finally,the performance test of the control system was discussed which showed that the control system based on IEEE1451 could perfectly finish the whole spray process with good spray effect.This paper provided an efficient technology approach for developing intelligent control system of steady state combustion fogger.
