Intellectualized water meter carrying out,not only may solve traditional water meter each month to copy the trouble which the table,the charge brings and the dispute which because the charge question brings,also may technically for save the water used,the reasonable water used creates the condition.
The present paper mainly introduced uses the ARM nucleus widely take at present as the foundation intelligent water meter design,elaborated in detail based on the ARM data acquisition,processing and the memory process as well as carries on the data transmission through the TCP/IP agreement and the main engine the process.The paper first has made the comparison to the commonly used sensor,elaborated this design choice does the reed pipes to take the sensor the reason.But after introduced systematically take ARM as the core intelligent water meter control system hardware architecture and the software realization.
Hardware architecture mainly involves to the processor,the memory and the network connection design.The software part mainly includes the data acquisition,processing,the demonstration as well as the TCP/IP network protocol realization.
The present paper designs the intelligent water meter which completes to have the function practical,the measurement accurate,the correspondence reliable merit.His promoted use will enhance the water used management the automated level,conforms to the establishment which the country will propose to save society's spirit.
Key word:ARM; TCP/IP agreement; Intelligent water meter; Data acquisition
自动化专业就业数据分析:
自动化专业的毕业生可以在通信公司、工厂企业、铁路、民航、海关、工矿企业及政府部门从事与自动化相关的工作,如自动化设计师,主要从事自动化系统的设计和开发工作;自动化工程师,主要是根据客户需要编写自动化控制项目方案书、组织自动化施工,并负责项目的技术指导工作,想要达到工程师的程度,除了能熟练的编写PLC程序、VBA程序,对SQL数据库、现场的工业常规仪表熟悉之外,必须有负责大型项目设计、管理、施工的经验。另外还需要在国家核心期刊上发表过学术论文,或是被同行公认的有较高学术价值的译文。另外,因为许多行业都与自动化专业挂钩,因此学习自动化专业转行相对较容易,可以转行到计算机、通信、电了工程领域谋发展。
自动化的渊源可以一直追溯到2000多年以前,我国汉朝时期的指南车是最早的自动化设备。而真正意义上自动装置的出现,公认是在18世纪前后(大约在1788年左右)蒸汽机的诞生。所谓自动化,即机器或各种各样的装置,在无人干预的情况下按规定的程序或指令自动进行操作或控制,并按要求完成相应的工作任务的过程,其目标是“稳、准、快”。采用自动化技术不仅可以把人从繁重的体力劳动、部分脑力劳动以及恶劣、危险的工作环境中解放出来,而且还能扩展人的器官功能,极大地提高劳动生产率。
