| Abstract: | A trailable force tester was proposed and designed to detect the magnitude and variation of trailable force for hydraulic switch machine.The hardware platform and software platform of this tester were established through the LPC2214 chip of ARM7 micro controller and the ｜ìC/OS-II real-time Operating System.The real-time changes of trailable force could be displayed in the form of both digit and curve through LCD.Besides,the test data could be stored and transferred to PC through RS232 or USB port,then the data could be analyzed and the results could be printed out.According to the practical application,this tester could completely fulfill the design requirements,and had many advantages such as good stability,high precision and strong anti-interference performance. |
