It is the embedded system structure overhead control platform of core that controller adopts with the STM32 single-chip microcomputer, is responsible for the running of control alternating current generator; The collection of data, demonstration and storage.The controller interface is made up of with display pressure button, pulling force button, zoom button, home key, zero clearing button, reset key, rising button, decline button.Button can be controlled just commentaries on classics, the counter-rotating of motor; The selection of pulling force, pressure; The convergent-divergent of data zero clearing and pressure curve etc.Display is divided into the TFT screen and shows that following computing machine demonstration two parts: TFT to shield can show pressure curve in real time, and computing machine can carry out calculating such as maximum pressure value, shearing acting when showing pressure curve in real time.
Spring motor is made up of transmission gear, speed regulator, clockwork spring, non-return mechanism and handwheel.
Outstanding advantage of the present utility model is:
The first, for manually--the automatic dual-purpose formula, can under the condition of the field unregulated power energy, use, solved the problem that can not test when lacking electric power.
The second, the ARM Cortex-M3 that adopts the advanced person is that the STM32 processor of kernel is made master controller, has improved the performance of whole instrument.
The 3rd, can obtain pressure curve, solved because of the simple weakness of intuitive difference when showing maximal value
The 4th, can carry out the calculating of maximal value and acting, data analysis capabilities strengthens.
The 5th, the whole instrument volume is little, is easy to carry about with one, and is easy to use.
