In order to improve the level of automation about the traditional small henhouses, a set of remote environment control system of telligent network henhouse is designed by combing ARM and ZIGBEE network technology with traditional henhouse construction in this paper. This system took the S3C2440 of ARM9 microprocessor as the core,and Linux system as development platform to realize data collection and transmission through the ZIGBEE wireless sensor network, so that culturists can remote control and monitor the facilities and indicators in the henhouse simply through broadband network, the labor intensity is greatly reduced and the working efficiency is raised

This essay puts forward a multifunctional numerical control system, which is on the basis of ARM9 core microprocessor. It takes Samsung S3C2440A microprocessor as its operation core, in the pattern of dual-CPU, in order to automatically operate the processing. The control center plays the part of inputting the digital control program, keyboard inputting, LCD displaying, the explanation of the programs, crude interpolations and so on, with CPU as the assisting apparatus to realize fine interpolation. To expand the human interface and communication module, and fix an 8-inched multicolor display screen, in order to realize the human interface and communicate. The hardware platform is modularized, which makes the maintenance and upgrading of the system much easier. This system is low in power consumption and cost, which can realize many operations such as digital operation, combing shining metal and machine together, probing and so on; as a result, it is promising.

This paper introduces a design of detection instrument according to the principle of photoacoustic spectroscopy based on the ARM to test trace gases in transformer insulating oil. This detection instrument makes embedded ARM9 as its center. On the principle of photoacoustic spectroscopy, using microcontroller, lock-in amplifier to achieve the detection of trace gases in the transformer insulating oil. The article presents the hardware design method of the instrument, and validated by experiment. The instrument has the features of simple structure, easily operate, real-time online testing and so on. It has important significance for the maintenance of the transformer.
