项目摘要

In the field of process control, the Information technology advances most in comparison with other field. However, there is seldom an electrical infrastructure necessary for the information technology, because the process equipment is used in the place with explosion hazard-ness. The purpose of this study is to propose the new electrical power generating system from the pneumatic power that actuates process instruments, and to develop this. The vibrator part of the proposed generating system consists only of piston and cylinder and generates the self-induced vibration. The coil is installed at the top of piston and the movement of the coil in magnetic field generates electricity. It is a very simple mechanism. The research was mainly carried out on efficiency and analysis, pressurized air bearing at the piston, rectifier circuits of the electricity energy of the generator. The outline of research is concretely shown in the following.1. The efficiency of the proposed generator was very low. However, when its parameters were changed adequately, the efficiency has the highest point for the parameter where it is over 10%.2. It is necessary to realize noncontact between the piston and cylinder in order to obtain the long life of the generator. Then pressurized air bearing being with the stepped shape is installed the generator. The performance is analyzed of the bearing and has sufficient for the generator.3. In proposed generator, rectifier circuits are also important problem because a process instruments needs DC power source. Rectifier circuits am made and electric power is supplied a process instruments the through it. The generator is able to drive the process equipment, though the fluctuation of electric power could not be followed.

在过程控制领域中，信息技术的发展是最快的。然而，由于工艺设备用于具有爆炸危险性的场所，信息技术所需的电气基础设施很少。本研究的目的是提出一种新的发电系统，从气动驱动过程仪表，并开发这一系统。该发电系统的振子部分仅由活塞和气缸组成，产生自激振动。线圈安装在活塞的顶部，线圈在磁场中的运动产生电流。这是一个非常简单的机制。主要对发电机的效率及分析、活塞压气轴承、发电机电能的整流电路进行了研究。具体研究内容如下：1.所提议的发电机的效率非常低。但当其参数适当改变时，效率在该参数下有一个最高点，在10%以上.为了延长发电机的使用寿命，必须实现活塞与气缸之间的非接触。然后将阶梯形的压缩空气轴承安装在发电机上。分析了该轴承的性能，并对发电机进行了充分的分析.在所提出的发电机中，整流电路也是重要的问题，因为过程仪表需要直流电源。整流电路通过整流电路向过程仪表供电，发电机可以驱动过程仪表，但不能跟踪电能的波动。
