Measurement And 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.

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.

The Coordinator

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.

In the domestic certification bodies the automation degree of the definitive test of the accessories products left much to be improved, as for safety of the transformer conforming to the international standard of IEC61558-1, the traditional manual testing method barely meets the requirements of sampling rate, and has caused a lot of technical deficiencies including inadmissible deviation in the calculation and post-processing of the related experimental data, lengthy work-time of staff, and low test efficiency. In this paper, concerning the type test of various electronic and power transformers, a set of intelligent automatic measurement and control system of the temperature rise test is presented, consisting of software packages with modularized designing and an original hardware apparatus with built-in control modules. Therefore this system is capable of performing a series of operations without human intervention, such as controlling of the related testing equipment, data analysis, real-time monitoring, timing acquisition and data processing of corresponding algorithms, auto-save of test configuration and generating original record of the test. Thus, the idea of ‘Full automation with only one simple configuration’ has truly been realized. The experimental results show that compared with the traditional testing method, the application of this system minimized uncertainty caused by human factors in the testing process and improve precision of data analysis, and also ensured the reproducibility, consistency and traceability of the test results effectively.
