Design Of Pulsation Vacuum Sterilizer Equipment Control System With Remote Monitoring Function

Along with the people’s understanding to infectious disease transmission, the hospital sterilization equipments were required to enhance, at the same time,sterilizer monitoring and remote control system research is still in blank.This paper is based on the STC89C52single chip as core part, with saturation pressure steam sterilization medium, use of high temperature and high pressure and high temperature steam condensation latent heat release out to the medical device is completely effective sterilization, After setting the constant temperature time of PID control combined fuzzy control, method for the goods completely effective sterilization, formed a set temperature, pressure signal collecting, monitoring, control, display and printing as one of the Pulsating Vacuum Sterilizer Controlling system.In this paper, based on a large number of literature search and analysis, Introduces the status quo for the Pulsating Vacuum Sterilizer Controlling system, and geothermal-depth analysis of the Pulsating Vacuum Sterilizer Controlling system. structure and the type of information network and its applications in the real limitations and shortcomings. This paper introduces the design of temperature and pressure monitoring module and remote monitoring the temperature and pressure signal of the GPRS module, introduces the hardware aspects of safety performance and resistance to external interference factors of ability. The system of the sterilization containers and multiple monitoring stations vessel wall distributed monitoring, USES the current mature TCP/IP protocol, through the GPRS wireless network transmits the collected temperature, pressure data; Realize data from the client to the remote transmission of data centers, and the transmission of data to carry on the analysis judgment and then give feedback to the single chip makes the corresponding drive control. And establishes a fuzzy PID control model basing on the Pulsating Vacuum Sterilizer Controlling system. In the steam pressure deviation and cavity wall temperature deviation and deviation in the rate of change for inputs, output for control thyristor hige time variable, Established the input2D output one-dimensional fuzzy PID controller. Software design using fuzzy PID algorithm, able to fully control the sealing pressure within the container vapor formation, reduced working hours, achieved good sterilization effect. Position machine configuration software was used in the United States National Instrument Company which developed the Labview configuration software,.This software is a graphical programming language development environment and is also a standard data acquisition and instrument control software. It send the configuration information and control information to the terminal of Sterilizer Controlling System, and receives the breakdown warning information of pressure and temperature data.At the same time, the collection of data storage, query, statistics, reports and other functions.The control system has high degree of automation, control system reliability, friendly man-machine interface, can be real-time monitoring features, has a strong practical value.
