With the development of electron and computer, automatic meter reading system has a possibility to be put into reality. Especially for the well-to-do uptown, the Construct Department of China has demanded to realize integrate management of kilowatt-hour meter step by step, gradually to realize automatic meter reading , measuring and charging with computer.

随着电子和计算机技术的发展，实现多用户能耗仪表的自动抄录已经成为可能，特别是建设部提出了小康型住宅小区的规划要求，并逐步实行能耗仪表出户的统一管理，实现微机自动检测、计量和收费。

Summary This design mission is a design that independence complete to the standard bore plank the boiler water supply discharge measures, completing to design the manual, the bore knothole design is an accuracy to measures the most important parts in inside in gauge, direct influence in quality in its function whole gauge even can use the sex.

摘要本次设计任务是独立完成对标准孔板的设计，完成设计说明书，孔板的设计是测量仪表中最为重要的部件，其性能品质直接影响整个仪表的精度甚至可用性。

In the process of realizing the remote control of electromotor meter, it probes into the realization of the GPRS wireless collector emphatically which is on the kernel ground. It adopts the means of area-centralizing control to manage the electromotor meters affiliated by it. It communicates with the central control station by GPRS Modem and transmits the commands and data to the instrument by wireless, which makes the collection and transmission of the field data come true. In the process of realizing the remote control of voltage transformer meter, according to the actual requirement, it adopted the chips and modules that are different from the front means to design and realize the GPRS wireless communicating controller corresponding with the devices. It also introduces the mixed—mode Communication integrating the GSM with GPRS to settle the problem that too many GPRS terminals connecting with the central control station synchronously will affect the performance of the central control station.As a whole system, the central control station is the kernel of the digital oil field.

在油田电机表远程控制方案实现中，着重介绍了处于核心地位的GPRS无线集中器的实现，它采用区域集中控制的方式管理下属的石油电机表，与主控站采用GPRS Modem进行通信，与仪表则采用无线电方式进行命令和数掘的传输，实现了现场数据采集传输；在配电变压器表远程控制方案实现中，根据应用需要，采用与前一个方案完全不同的硬件芯片和模块，设计实现了与仪表设备——对应的GPRS无线通信控制器，并针对同时挂接在主控站上的GPRS终端太多会对主控站性能产生一定的影响这个问题，引入了GSM和GPRS相结合的混合通信模式。

Replanting the embedded real-time OS into the intelligent apparatuses make the function more flexible and the development of software more regular, and realize program modularized and shorten the development time.

在智能仪表中移植嵌入式实时操作系统使得仪表的功能更加灵活，并且使软件开发变得规范、容易测试，有利于实现模块化编程和缩短开发周期。

Their main frame, along with forks, wheels and everything under the panels, is painted matt black. Colored paint is limited to panels, leg shields, headset, horn casting and the front mudguard.

车身，前叉，车轮及仪表板下的所有部件喷涂亚光黑漆，光漆的喷施仅限于仪表板，脚防护板，碗组，前鼻与前挡泥板。

Although not a precision instrument, the ohmmeter is a useful device for rapid measurement of resistance.

欧姆计是一种很有用的仪表，可以用来迅速地测量电阻，尽管它不是一种精密仪表。

The intelligent instrument with a singlechip of 89C51 and a chip 8155 realize the oscular minimum hardware design technique for keyboard/display and printers .
