遥测桅英语怎么说及英文翻译
㈠ 英文缩写的全文或中文翻译
TDM:时分复用和复用器
(TDM:Time Division Multiplex and Multiplexer)TDM:时分复用和复用器
(TDM:Time Division Multiplex and Multiplexer)
时分复用是指一种通过不同信道或时隙中的交叉位脉冲,同时在同一个通信媒体上传输多个数字化数据、语音和视频信号等的技术。电信中基本采用的信道带宽为 DS0,其信道宽为 64 kbps。
电话网络(PSTN)基于 TDM 技术,通常又称为 TDM 访问网络。电话交换通过一些格式支持 TDM:DS0、T1/E1 TDM 以及 BRI TDM。E1 TDM 支持2.048 Mbps通信链路,将它划分为32个时隙,每间隔为64 kbps 。T1 TDM 支持1.544 Mbps 通信链路,将它划分为24个时隙,每间隔为64 kbps,其中 8 kbps 信道用于同步操作和维护过程。E1 和 T1 TDM 最初应用于电话公司的数字化语音传输,与后来出现的其它类型数据没有什么不同。E1 和 T1 TDM 目前也应用于广域网链路。BRI TDM 是通过交换机基本速率接口(BRI,支持基本速率 ISDN,并可用作一个或多个静态 PPP 链路的数据信道)提供。基本速率接口具有2个64 kbps 时隙。TDMA 也应用于移动无线通信的信元网络。
时分复用器是一种利用 TDM 技术的设备,主要用于将多个低速率数据流结合为单个高速率数据流。来自多个不同源的数据被分解为各个部分(位或位组),并且这些部分以规定的次序进行传输。这样每个输入数据流即成为输出数据流中的一个“时间片段”。必须维持好传输顺序,从而输入数据流才可以在目的端进行重组。特别值得注意的是,相同设备通过相同 TDM 技术原理却可以执行相反过程,即:将高速率数据流分解为多个低速率数据流,该过程称为解除复用技术。因此,在同一个箱子中同时存在时分复用器和解复用器(Demultiplexer)是常见的。
CDMA即code-division multiple access的缩写,译为“码分多址分组数据传输技术”,被称为第2.5代移动通信技术。目前采用这一技术的市场主要在美国、日本、韩国等,全球用户达9500万。CDMA手机具有话音清晰、不易掉话、发射功率低和保密性强等特点,发射功率只有GSM手机发射功率的1/60,被称为“绿色手机”。更为重要的是,基于宽带技术的CDMA使得移动通信中视频应用成为可能。
DTE就是我们数据终端设备,我们的ADSL MODEM,一台PC都可以说是一台DTE,他们通信有一个时钟来保持同步,这个时钟由DCT来提供。
WDM(Win32 Driver Model),即Win32驱动程序模型,是Microsoft力推的全新驱动程序模式,旨在通过提供一种灵活的方式来简化驱动程序的开发。在实现对新硬件的支持上,减少并降低了所必须开发的驱动程序的数量和复杂性。除了通用的平台服务和扩展外,WDM还实现了一个模块化的、分层次的微型驱动程序结构。WDM驱动的主要特点是可以让不支持多音频流的声卡支持多音频流,不使用音频线直接听音乐CD等。
HDLC:High Level Data Link Control protocol,高级数据链路控制协议是基于的一种数据链路层协议,促进传送到下一层的数据在传输过程中能够准确地被接收(也就是差错释放中没有任何损失并且序列正确)。HDLC 的另一个重要功能是流量控制,换句话说,一旦接收端收到数据,便能立即进行传输。

Infrared receiver circuit
Design uses a high-performance infrared receiver - telefunken
Root TFMS5380. Telefunken developed micro-receiver TFMS5380 is the highest in the recent market performance of the infrared receiver. The same components have been installed on the receiving diode and preamplifier. TFMS5380 characteristics: (1) a single receiver and a combination of pre-amplifier. (2) ultra-sensitivity and transmission distance. (3) built-in PCM frequency filter. (4) without the need for external components. (5) special light and electric field interference shielding. (6) TTL and CMOS compatible for operation control of the microprocessor. (7) optional frequency from 30KHZ to 56KHZ. (8) low power consumption. (9) ISO9000 accreditation.
TFMS5380 applicable to data transmission, television sets, video recorders, music centers, and satellite receivers, etc.. TFMS5380 and constitute the internal block diagram of the receiving circuit. Shown in figure 3.
The request was receiving circuit to receive the infrared light wavelength of about 950μ, the pulse width molation signal is not less than 600μs. TFMS5380 the application circuit is very simple. Experiments show, TFMS5380 good performance, fully meet the needs of data transmission.

3. Software Design
The system software design includes hand-held meter reading devices and host software from the software side of watt-hour meters in two parts. During the design of hand-held meter reading devices accept single-chip microcomputer to send characters with the way the characters are inquiries, send communications read before the state register, send inquiries to maintain any register empty, receive communications read before the state register, a data query End has closed. Watt-hour meter single-chip approach using interrupted, that is, the address frame received after the application for the serial port interrupt, interrupt response, the interrupt service routine to enter.
Handheld meter reading software design:
In infrared communication, the handheld meter reading device as a host is the initiator of communication, the sending and receiving are active, and its specific work process: continuously scan the keyboard, if found to have the command key pressed, then call Send subroutine to send the corresponding command, sending soon start receiving end subroutine to receive return information watt-hour meter, and then docking received follow-up information processing. Hand-held meter reading devices, including communication program initialization subroutine and serial communication program, the process shown in Figure 4.
Subroutine to initialize SP-INIA, mainly on communications baud rate and mode settings, the program source code is as follows:
SP_INIA: MOV TMOD, # 20H; select Timer T1 mode 2, timer mode
MOV TH1, # 0E8H; preset time constant
MOV TL1, # 0E8H
CLR ET1; prohibited from time to time interrupted
SETB TR1; start timer
MOV PCON, # 80H; SMOD = 1
MOV SCON, # 0D8H; manner 3, SM2 = 0, REN = 1, TB8 = 1
SETB EA; open total interruption
SETB ES; open serial port interrupt
RET
Serial communication program meter reading slightly;
Watt-hour meter software design: watt-hour meter as a client from the machine, its software programs, including the main program and interrupt service routine, flow chart shown in Figure 5;
4. Concluding remarks
This article describes the application of watt-hour meter IR meter reading system in single-chip serial communication interface with the hardware circuit is simple, low-cost and easy programming, communications and high reliability. Use of hand-held meter reading devices can be easily completed the of the watt-hour meter and calibration work has greatly enhanced the efficiency of meter reading and meter reading accuracy and to eliminate the estimated high and the of the issue of misuse. In this paper, the communication protocol can be more than one single-chip transmit data securely, to achieve the communication of both non-contact transmission of data, can also be used for other remote control, remote sensing of single-chip applications.
