Monitoring And Control On Evaluation System Of Anti-vegetation Smoke Interference For Detector Equipment

In the process of modernization of national defense,the chemical detector equipment must be evaluated before use.The evaluation system of is used to evaluate the chemical detector equipment performance of Anti-vegetation smoke gas interference.As many manual operations are used on the original equipment,the amount of smoke and concentrations of dilution vegetation smoke are not controlled effectively,there is a big error in the process of chemical detector equipment evaluated.In order to improve efficiency and accuracy of evaluation system of Anti-vegetation smoke interference,the evaluation control system of Anti-vegetation smoke interference is designed based on modern industrial control technology.First,the principle of wood smoke and gas distribution is introduced,and then the whole design plan of automation control is proposed based on technological process,the control system of hardware selection and software design are completed.Asked to choose Siemens300 PLC controller is choose as the core of the control system based on the performance of the system,the method of selection and use of the module of PLC is specified.The choice of actuator is completed,servo control systems and analog signal processing are described.The evaluation control system of Anti-vegetation smoke interference software includes two parts of the PLC program and computer monitoring program,the software is developed with LAD and SCL language.The software system is modularized and each functional module is a subprogram.The function of the system is implemented while the main program calls the subprograms.The communication program of the PLC and smart instrument is described.The Siemens 300 series PLC special programming software Step7 which has a friendly interactive interface to write programs and online debugging easy is used to programming.The generic configuration software INSPEC is used as the design platform of PC monitoring program which is used to operate the system and collect data.The monitoring program includes the main interface,the interface of manually adjust,the interface of real-time data display,the interface of historical data show and the interface of database user.SQL2005 database software is installed in the PC,The key real-time data is stored in the database by designing script with INSPEC.The debugging work of evaluation system of Anti-vegetation smoke has been finished,the system is stable and reliable to meet the demands of the evaluation work of anti-vegetation smoke interference.
