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.

ABSTRACT”Magnetics sensors” are the key devices to establish intelligent electronics measurement and control systems for development of high level factory automations ( FA ). Various magnetics sensors having quick response, high sensitivity and robustness have been widely developed in these years using amorphous magnetic alloys, magnetoresistive ( MR ) elements, soft ferrites, and high temperature superconductors. These high-performance sensors are spreading in use in the fields of Power-Electronics ( Power Magnetics ), Mechatronics, Medical Electronics ( Medical Magnetics), Information Apparatus, Security Electronics ( Security Magnetics ) etc..Relations between new magnetic materials and high-performance sensors are summarized and a principle for constitution of these sensors is proposed.
