随着城市绿化事业的发展,绿化浇水要求节约、自动化.文章针对现有绿化水炮装置的不足,研制了一款通过图像实时遥控,实现浇灌喷洒均匀的新型视觉遥控自动全方位洒水车绿化水炮装置,能够改善工人工作环境、安全可靠、工作效率高.

As people pay more attention to environmental protection and energy saving, a kind of environmental protection and energy saving self-propelled trolley without electric drive is designed. The trolley is based on the law of conservation of energy, without any other power, driven by gravitational potential energy of its heavy farmer. Through the design of mechanical mechanism, the trajectory of "8" shape is realized, and the shape of trajectory can be adjusted. The distance of walking depends on the exhaustion of gravitational potential energy. No electric drive self-propelled dolly has the advantages of simple working environment, energy saving and environmental protection. It has a good application prospect in both student competition and children's toys.

The domestic and foreign existing methods and techniques for class roll call are analyzed. Aiming at the existing problems, this paper designs a combination of Bluetooth and gravity detection of class roll call mobile phone management system. The basic working principle of the management system is analyzed. Its structure, functions and procedures are analyzed and designed. The system's technical architecture and the corresponding steps are given. And through the actual class proves the practicability of the system. Under the actual background, the method of accurate call by mobile phone is studied. Multifunctional class roll call management system for mobile phone has real-time transmission, accurate data. It avoids the students watching the phone in class.

随着中国的经济腾飞,私家车不再是财富的象征,而步入普通人家,然而车辆保护不当问题的日益严重,本文针对现有车罩的不足,研制出一款一种可移动、可收缩、多层下放设计的保护装置,使用龙门框架结构[1]、配合常用的STM32[2]、步进电机和Wi-Fi模块组建而成的、使用了手机APP等多种控制方式以及拥有不同模块化配置以满足不同人群需求的"罩动车不动"车辆智能保护罩.
