Measurement And Control System Of Air Compressor Based On PLC Configuration Control

The research background herein puts forth effort on the research and development production of the refrigeration compressor,with the constant innovation of the refrigeration compressor technology,trade this national efficiency standard adjustment in production system,new product research and develop,number of runs quality testing release,try,control,standard machine customer give kind terms of question influence,in addition the restricting relatedly of environmental protection technology,thereupon have higher requirements to its product test's craft,technical force,efficiency.For realize products accuracy of function test,count,produce performance of compressor of air conditioner based on that PLC configuration controls observe and control the system while being adhoc,commonly called as the calorimeter.Designing and making it in the course in the whole apparatus,consider PLC function is abundant,performance is steady,dependability is high,have the characteristics of abominable environments such as high temperature,impact and vibration which meet the industrial scene etc.Therefore in industrial production control and management,more than nearly 80%of the work can be finished by PLC.Can replace the control device of the relay and finish the order to control and control with the procedure at the same time,regulate PID return circuit,can form the high-speed data gathering and analyticl system too,position control and pace of making the ring control.It is ocular for touch-sensitive screen to reveal,with PLC being communication simple and reliable,PLC + system of observing and controlling that touch-sensitive screen makes up,the development environment is simple and convenient,measure the precision high,with strong anti-interference ability,totally adapt to meeting and observing and controlling the demand the complicated factory environment online.This system has offered a swift and effective method for testing development and application of the apparatus.The performance of compressor of air conditioner based on that PLC configuration controls observes and controls the system,set out from solving the practical problem.In alreadying the platform that will the environmental refrigeration operating mode of the national standard will take place soon put up and build up,urged by PLC configuration control system the hardware of unit happen to all industrial and mining.Have created information and gathered the passway,carried the long-range software to gather the information process system,mean the function that the course of whole product test has possessed science,observed in real time,obtained the test result fast.Make refrigeration trade develop with high efficiency,high-levelly and march toward the new step.In sum,the research engaged in this direction has very great application prospect and practice meaning.This thesis,through the second refrigerant law is mainly examined,the cold matchmaker's flow meter law complements and examines the way to analyze,put up particular hardware platform and software platform construct,test system realize to make cold compressor performance perfect to measure,it measures precision to limit to 5%.Research of thesis this with realize not merely turning thermodynamics operating mode into electricity count way analyzed to examine quote get refrigeration successful application of system,use the intellectual software of the data analysis to study the system of huge and complicated refrigeration to introduce from laboratory to the category of the integrative type at the same time,have reflected that gathers and operates melting,high-efficient direction development trend intelligently and briefly in data,test the design of platform and realize a new reference method of offering in order to make cold compressor too.
