Mechanical properties of MEMS materials is one of MEMS important basic theory research, including hardness, elastic modulus, yield strength, tensile strength, fatigue strength and other performance indicators. For the acquisition and processing of weak signal can meet the system, this paper designs a measurement and control system which has a common set of software and hardware of high speed, high accuracy, high reliability in one. This tester is mainly composed of four parts: precision positioning subsystem, specimen clamping subsystem, load/displacement measurement subsystem and measuring and controlling subsystem, which provides a solid foundation in higher positioning accuracy of measuring MEMS materials and benefits more for further research.

This paper will give a solution of measurement and control system based on FPGA embedded system for the Plastic Material Dynamic High-speed Tensile Machine (PMDHTM) with 1-100s-1strain rate range. Using sub-modules design of Nios II soft-wore and SOPC to build measurement and control system. The state machine algorithm and servo drive device are applied to accomplish precise state control of the linear shaft motor. Collecting the stress data online and non-contacting strain measurement is adopted. The test result can well meet the linear motor control response demand below the 5Hz frequency. Compared with other control based on SCM, DSP and so on, it supplies an innovation way for the PMDHTM control.

In order to meet the high speed, high precision, high reliability of the packaging machine, a novel control system is provided. In the hardware, the main circuits consisted of main processor module, memory module, temperature measurement and control module, input signal detection module, material split packing module, output driver module, human-machine interface module, system monitor module, power module and JTAG debug module, etc. In the software, the multi-tasking operating system μC/OS-Ⅱ and the graphical user interface μC/GUI were successfully transplanted into LPC2478. Then an experimental platform was established. And many control tasks, including automatic measurement, making bags, loading, transferring, pumping vacuum, sealing and data display, were automatically and continuously executed on the platform. Finally the results show: the machine can package 30 packets (5 g per packet) in a minute; the packaging errors ≤ 0.2 g; the packaging qualified rates ≥ 93%. In conclusion, the system performance is good.

Based on the problem of complex wiring, low anti-interference capacity and high cost in wired measurement and control system, we developed and designed a cable parameters acquisition and control system based on ZigBee technology. The system was composed of upper PC, a coordinator node and five data collection nodes, presents the hardware circuit and software design method of the coordinator node based on CC2530, and developed the PC management software based on LabVIEW. By the measurement that five data collection nodes are distributed in the indoor, the actual results show that the system is stable, and high reliability.

A network measurement and control system based on STM32 is designed for the control of greenhouse temperature, humidity, carbon dioxide concentration, etc. ModbusRTU serial bus is used for managing the greenhouse environment instrumentation network and signal acquisition. The remote control of greenhouse is achieved by LWIP Ethernet and Modbus/TCP communication protocol, and the network control of multispan greenhouse is realized by them. MCGS(Monitorand Control Generated System) is used for the design of human machine interaction. The control system can reach producing requirements, high reliability, easy to operate and maintain.
