【摘要】 在化学学科及其他学科的实验中,水浴锅是一种常用的制作材料的设备。水浴锅主要用于实验室中蒸馏,干燥,浓缩,及温渍化学药品或生物制品,也可用于恒温加热和其它温度试验,是生物、遗传、病毒、水产、环保、医药、卫生、化验室、分析室、教育科研的必备工具。可以说,在全世界范围内的所有高校以及研究所的每一个实验室,都存在水浴锅,并且使用频率较高。然而,水浴锅的安全问题是一个比较重要的问题。使用水浴锅时必须加入去离子水,以防止水浴锅内产生水垢。加水不可以加太多以防止水量溢出。工作完毕之后要将温控旋钮旋转到最小值处。其中,最为关键的一条就是要防止水浴锅干烧。由于水浴锅的温度通常比较高(60℃-80℃),水蒸发的非常快,当水浴的时间较长时,水浴锅的水很容易就下降到加热丝以下,此时会导致加热丝裸露在空气中,造成干烧,容易使水浴锅损坏,情况严重的甚至会引起火灾。本文基于对水浴锅寿命的延长以及实验室安全考虑,制作了一个水浴锅自动加水系统以及基于Android系统的手机APP。本文基于51单片机为GPU,通过蓝牙串口模块与手机通信,将实时水位信息传到手机APP中。通过测距系统测量水浴锅中的水位信息,当水位较低时,通过51单片机控制水泵的开关,将水箱中的水加入到水浴锅中,保证水浴锅的寿命以及实验室的安全。更多还原

【Abstract】 Water bath is a common device for making materials in experiments of chemistry and other subjects.Water bath is mainly used in laboratory distillation for drying,concentration,and temperature-sensitive chemicals or biological products.It can also be used for constant temperature heating and other temperature tests.It is a necessary tool in biological,genetic,viral,aquatic,environmental,medical,health,and laboratory,analysis room for education and research.It is said that water bath has a high using frequency in all the universities and laboratories in the world.However,the safety of water bath is an important problem.Deionized water must be added when using the water bath to prevent scale formation.Adding too much water is not suitable because of overflowing.When an experiment is finished,we must turn the temperature knob to the minimum value.Moreover,the most important one is to prevent the water bath from drying without water.Since the temperature of the water bath is usually high(60 °C-80 °C),water in the bath will evaporate quickly.When the water bath is working for a long time,the water in the water bath will easily drop to the heating wire,which will cause the heating wire to be exposed in the air.Dry burning for a long time will cause the water bath broken.The most danger situation may be fire even.This paper based on the extension of the life of the water bath and the safety of the laboratory,produced a water bath automatic adding water system and a mobile phone APP.This system drops MCS-51 as the GPU,communicates with the mobile phone through the Bluetooth module,and transmits the real-time water level information to the mobile phone APP.The water level information in the water bath is measured by the distance measuring system.When the water level is lower than heating wire,the water pump will begin to work in the controll of the MCS-51.The water in the water tank will be added to the water bath to ensure the life of the water bath and the safety of the laboratory.更多还原
