遙測桅英語怎麼說及英文翻譯
㈠ 英文縮寫的全文或中文翻譯
TDM:時分復用和復用器
(TDM:Time Division Multiplex and Multiplexer)TDM:時分復用和復用器
(TDM:Time Division Multiplex and Multiplexer)
時分復用是指一種通過不同信道或時隙中的交叉位脈沖,同時在同一個通信媒體上傳輸多個數字化數據、語音和視頻信號等的技術。電信中基本採用的信道帶寬為 DS0,其信道寬為 64 kbps。
電話網路(PSTN)基於 TDM 技術,通常又稱為 TDM 訪問網路。電話交換通過一些格式支持 TDM:DS0、T1/E1 TDM 以及 BRI TDM。E1 TDM 支持2.048 Mbps通信鏈路,將它劃分為32個時隙,每間隔為64 kbps 。T1 TDM 支持1.544 Mbps 通信鏈路,將它劃分為24個時隙,每間隔為64 kbps,其中 8 kbps 信道用於同步操作和維護過程。E1 和 T1 TDM 最初應用於電話公司的數字化語音傳輸,與後來出現的其它類型數據沒有什麼不同。E1 和 T1 TDM 目前也應用於廣域網鏈路。BRI TDM 是通過交換機基本速率介面(BRI,支持基本速率 ISDN,並可用作一個或多個靜態 PPP 鏈路的數據信道)提供。基本速率介面具有2個64 kbps 時隙。TDMA 也應用於移動無線通信的信元網路。
時分復用器是一種利用 TDM 技術的設備,主要用於將多個低速率數據流結合為單個高速率數據流。來自多個不同源的數據被分解為各個部分(位或位組),並且這些部分以規定的次序進行傳輸。這樣每個輸入數據流即成為輸出數據流中的一個「時間片段」。必須維持好傳輸順序,從而輸入數據流才可以在目的端進行重組。特別值得注意的是,相同設備通過相同 TDM 技術原理卻可以執行相反過程,即:將高速率數據流分解為多個低速率數據流,該過程稱為解除復用技術。因此,在同一個箱子中同時存在時分復用器和解復用器(Demultiplexer)是常見的。
CDMA即code-division multiple access的縮寫,譯為「碼分多址分組數據傳輸技術」,被稱為第2.5代移動通信技術。目前採用這一技術的市場主要在美國、日本、韓國等,全球用戶達9500萬。CDMA手機具有話音清晰、不易掉話、發射功率低和保密性強等特點,發射功率只有GSM手機發射功率的1/60,被稱為「綠色手機」。更為重要的是,基於寬頻技術的CDMA使得移動通信中視頻應用成為可能。
DTE就是我們數據終端設備,我們的ADSL MODEM,一台PC都可以說是一台DTE,他們通信有一個時鍾來保持同步,這個時鍾由DCT來提供。
WDM(Win32 Driver Model),即Win32驅動程序模型,是Microsoft力推的全新驅動程序模式,旨在通過提供一種靈活的方式來簡化驅動程序的開發。在實現對新硬體的支持上,減少並降低了所必須開發的驅動程序的數量和復雜性。除了通用的平台服務和擴展外,WDM還實現了一個模塊化的、分層次的微型驅動程序結構。WDM驅動的主要特點是可以讓不支持多音頻流的音效卡支持多音頻流,不使用音頻線直接聽音樂CD等。
HDLC:High Level Data Link Control protocol,高級數據鏈路控制協議是基於的一種數據鏈路層協議,促進傳送到下一層的數據在傳輸過程中能夠准確地被接收(也就是差錯釋放中沒有任何損失並且序列正確)。HDLC 的另一個重要功能是流量控制,換句話說,一旦接收端收到數據,便能立即進行傳輸。

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.
