Abstract:Aiming at the problem that the solenoid valve performance test equipment is not convenient to carry,a portable solenoid valve performance test system based on microcontroller unit(MCU) and Android mobile phone terminal was designed.In the system,the Android smart phone was used as data processing center,STC15W408AS microcontroller was used as main control chip,combined with 511 series pressure sensor,CC2540 bluetooth module and other devices and control software,the functions of solenoid valve status data collection,real-time display,performance test and data sharing were achieved.The results show that the mobile APP developed with the help of Android Studio fully embodies the advantages of human-computer interaction;the system has the advantages of simple structure,convenient use,reliable test accuracy,meets the national solenoid valve performance test standard,and can be effectively used in the field rapid test of solenoid valve.
