为了给人们的生活提供方便,珍惜能源,节约用电,以STC89C52单片机为主控芯片,设计了节能饮水机控制系统。通过两个DS18B20温度探头将热水水温和温水水温实时送入STC89C52单片机,并采用液晶显示器LCD1602显示当前热水和温水水温,以及温水水温的设定值上限和下限。当热水烧好后,通过继电器自动控制加热器关闭并语音提醒人们热水可以饮用。当温水准备好后,通过继电器自动关闭温水池和热水池之间的电磁阀,以及温水池的进水电磁阀,并语音提醒人们温水可以饮用,避免了热水反复加热,温水水温数据误差在0.3℃以内,可以满足不同使用者对温水水温的需求。该饮水机节能,使用安全方便,成本低,可以随时为人们提供热水、温水、凉水,而且具有温水水温设置等功能。 相似文献

ContextWhile the ISD process and in particular Requirement Elicitation has been defined as a collaborative social interaction, visualisations fail to accurately capture the multifaceted nature of the social process. Instead, ISD visualisations focus on presenting a more mechanical/technical perspective, ultimately restricting an opportunity to better analyse the process.ObjectiveWith particular focus on Requirements Elicitation this study utilises the narrative network technique to visualise the ISD process as a live routine with the aim to detail the ideal and actual aspects of ISD. The ideal aspect consists of the abstract, generalised understandings of the human actors regarding enacting a routine. Being a live routine, the reality is that adjustments/variations are a common occurrence and need to be taken into account. Enabling the opportunity to identify patterns of action within the routine, the study also incorporates organisational mindfulness to provide further social analysis of these patterns of action.MethodIn light of the lack of theoretical maturity around the viewing of an ISD process as a ‘live routine’, this exploratory research sought to build theory using a single instrumental case study spanning over 3 years (several ISD projects) and a variety of methods (e.g. workshop, experiment).ResultsVisualising the ISD process as a live routine it was possible to identify a number of patterns of action. These patterns were triangulated against the organisational mindfulness analysis of the case data to highlight underlying mindless behaviours. A rule was then implemented (experimentally) during the first iteration of a new ISD project and notable improvements in the ISD process were observed. Furthermore, the knock on organisational impact of the experimental implementation of the rule is also examined.ConclusionFrom a practitioner perspective the study provides an alternative method for analysing the ISD process of an organisation and highlights the benefits of observing the ISD process as a live routine. From an academic perspective, contributions are made to both the ISD and Organisational body of knowledge. 相似文献
