Micro Vibration

As a typical inertial sensor, vibration micro-gyro is extensively studied. According to its working principle, drive control system is an important element for the gyro system. The role of drive control system is to keep the drive modal stability including stable vibration frequency and amplitude. The PLL method is usually used to realize the drive system. However, it has some shortcomings used to high Q vibration micro-gyro. In this paper, the problems of the PLL method are analyzed, and a PID & AGC control system is introduced. By simulating and measuring, it is indicated that this method is fit for driving high Q vibration micro-gyro.

As one of Linux development directions, embedded Linux has many achievements and mature products. Its stability, reliability and the high efficiency is being proved by the facts. Linux has a great potential in the embedded area, which is loved by many businesses, scientific research units. The embedded Linux opens the source code, provides technical support widely and has good extendibility, supports a lot of hardware. All these are the advantages of embedded Linux. Touch screen has been an important human-computer interaction device, for they are light, flexible and take up less space. Most mobile devices offer a touch screen which is used together with a pen in order to take the role of the mouse for application control. A kind of touch screen control system based on ARM and Linux is introduced in detail. Circuit diagram and touch screen working principle is given. In this paper, touch screen driver based on embedded Linux is designed, analyzed and transplanted. Finally, touch screen can be used normally after calibrating.

At this time the development and technological advances encourage the people to change the ordinary life style extra ordinary life style, sophisticated, modern, and still give priority to security that become relatively high. Therefore human is required in order to adapt twith the condition that exist at this time. One of them is the development in the robotics world. Because the benefits of robot is very important in helping the human job or replace the role of humans life, either in industry or in other sector that have a control system respectively. Therefore designed a robot arm control system using a communication device that is familiar and almost every people use it. That is a handphone. The working principle of that device a command or input from handphone then transmitted to electronic circuit that used bluetooth media. There is also bluetooth at the circuit that work to continue use data or command from handphone. On microcontroller using IC ATMEGA 16 and the programing language C. From the microcontroller has set the motor DC on robot arm. Which will be driveraccording with instruction that given by that handphone

The introduction of information and digital technologies that support and support all technological processes in the field is an urgent need for the development and implementation of such technology. An organisationally complex and financially intensive project is necessary because of the wide variety of economic entities that differ in the size of production, forms of ownership and socio-economic conditions of production. Automated information control system for mobile units agricultural enterprise provides those-Niko-economic performance, optimum capacity utilization through the use of timely and reliable information on technology. Machine and tractor aggregates are appertained as control objects with variable structure, which is explained by possibility of the system formation from tractor or field machines mobile units with various purposes: tillable, cultivatable, sowing, harvesting and etc. This MTA feature was determined creation of digital control systems of two groups of automatic control and management of the basic energy and operational parameters: tractors, machines and vehicles as part of MTA. To the first group are appertained the automatic control system of tractor motor component loading, motion speed, frictional sliding. To the second group – automatic regulation system of operating depth, seed rate, treatment of liquid combined fertilizers and crop protection agents, filling and driving of various MTA. Novelty of researches consists in methodology of the organization of the centralized control and management of various technological processes at carrying out field works.
