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。

This paper proposed a new QoS control method of voice service. On one hand, it uses adaptive transmission strategy, such as AMC, power control, sub-carrier allocation and antenna selection, to realize the reliable transmission in physical layer. On the other hand, it adopts ARQ and RRM in the data link layer to control the time delay and jitter of voice services.

本文提出的语音业务QoS的控制方法，一方面通过物理层的自适应传输策略，如调制编码方式、功率控制、子载波分配和天线选择等相关技术来实现物理层的可靠传输；另一方面，通过链路层的ARQ技术和无线资源管理策略来控制语音业务的时延及时延抖动。
