One - wire bus is a new technique based on cdma and std. it has simple structure, low cost, direct control via computer or microprocessor and simple program. the new type of one - wire digital sensor, which is integrated with thermometer, a / d, controller, rom, ram, can communicate with server computer through 1 wire and without any other accessories, moreover, 64 sensors can share one single line which makes system structure concise and easy
新型的單總線數字傳感器集成了溫度檢測、 a d轉換、控制器、 rom 、 ram 、單線雙向數據傳送等功能於一體，只需要1根數據線，無需其他輔助器件即可實現傳感器與主機間的數據通訊，而且多達64個數字傳感器可以共用該數據線，使系統間的連接非常簡潔，適應于低成本的多點測試、集中控制系統。 -
In this thesis, assembler language was applied to program to realize dsp algorithm controller, which can perform such main computing as data collecting, self - adaptable distortion current detecting based on linear nerve cell, capacity voltage controlling in the side of direct current based on fuzzy control, pwm pulse width computing based on unsymmetrical rule sampling, etc. quick control speed ( one work period is 50 s ) and high accurateness feature largely in the controller
本文採用匯編語言編程實現了dsp演算法控制器，它完成了數據採集、基於線性神經元的自適應畸變電流檢測、基於模糊控制的直流側電容電壓控制、基於非對稱規則采樣的pwm脈寬計算等主要演算法的運算。該控制器具有控制速度快（一個工作周期為50 ） ，精度高等特點。 -
In vse, an index that is used by the system control and service programs to locate one or more sequential blocks of program information that are stored on direct access storage
在虛擬擴充存儲系統（ vse ）中，系統控製程序和系統服務程序使用的一種索引，用於對存儲在直接存取存儲器上的一個或多個順序的程序信息塊進行定位。 -
Pipelining and parallel technology, accompanying with fast fifo as cache memory, instead of direct program operation, are adopted in the scheme and increase the transmitting speed dramatically ; fpga ( field programmable gate array ) is applied to realize the complex control logic of the system and makes it integrative, flexible and fast ; 386ex based embedded system, along with vxworks real - time operating system is introduced to substitute the microcontroller based system to simplify the hardware design and enhance the overall performance of ssr, and will make the system more easier to be applied to the projects in the future
該設計方案採用了流水線和并行技術，配以快速fifo緩存的方式取代了直接對flash進行編程的方式，極大地提高了閃存晶元存儲數據的速率；採用fpga技術實現系統的主要控制邏輯，集成度高、靈活性好、速度快；採用基於386ex的嵌入式系統及基於vxworks的嵌入式實時操作系統，取代單片機系統及其編程，提高了系統的整體性能，減輕了硬體設計的負擔，且使系統研發的延續性好。 -
An index that is used by a control program to locate one or more blocks of data that are stored in separate areas of a data set in direct access storage
由控製程序使用的一種索引，用來對一個或多個數據塊進行定位，這些數據塊存儲在直接存取存儲器中數據集的分離區域中。
