一种防触电安全预警操割工具的研发及应用

为解决一线工作人员在正常运维和应急抢修工作中携带工具品类多,整体重,护管难,工具形状固定、功能单一,操作使用传统工具误碰带电体易发生人身触电的生产事故的问题,研发出一种可以提醒、照明、传递信号且易操作、砍伐和切割的成套多功能工具。实操结果表明,该多功能工具可以通过握持绝缘杆保持操作安全距离,通过采集电信号,发出声光预警提醒操作人员注意危险点识别;可以通过更换工具刀头变成不同种类多功能工具使用来提高工作效益,降低操作难度。实践证明,该多功能工具不仅具有传统工具的使用和操作功能,且携带方便、智能、整体轻,使用时能确保操作人员不被电伤及。

Adaptive Optimal Control of a Heavy Lathe Operation

To create control laws of the cutting process on the heavy lathe, the temperature-force model of optimization of cutting conditions for turning was selected. The models to manage the process of cutting on heavy lathe in real time were created. It was found that the optimization of the cutting process must be carried out according to the criteria： productivity, cost and tool life. The hardware structure of the adaptive control system for heavy lathe was developed and its dynamic performance was investigated. The system provides function of the cutting speed of adaptive control and the possibility of compensation of linear, nonlinear and temperature-related inaccuracies. Research results were implemented in the prototype of adaptive control system for heavy lathe and the integral complex of optimal control of an adaptive technological system.

我国研制成功纳米微操作机器人

一台能够在纳米尺度上操作的机器人系统样机前不久由中科院沈阳自动化所研制成功．并通过了国家“863”自动化领域智能机器人专家组的验收。这意味着能进入人类细胞内部工作的纳米机器人距离我们已经不太遥远了。
