low speed storage 中文意思是什麼
low speed storage
解釋
低速存儲器-
However, because of the low speed of program operation and the invalid blocks of flash memory, if we want to make it the storage medium of solid state recorder on the spacecraft, several problems need to be resolved : 1 ) how to improve the speed of program and erase operation of flash memory ; 2 ) how to map out and bypass the invalid blocks and effectively manage the mass memory space
但是由於flash的寫入（編程）速度慢、存在無效塊等問題，使要將其應用於星載大容量存儲器，亟待解決以下幾個問題： （ 1 ）如何有效地提高閃存的編程和擦除速度； （ 2 ）如何標識和旁路初始和使用過程中出現的無效塊，並有效地管理大容量數據存儲器。 -
In the flight experiment of aircraft, the mass data acquisition, storage and transfer is always one important part of system, especially for the measurement of parameters such as temperature and pressure of cockpit. in order to meet these needs, we design this simultaneous data acquisition system with multi - channel and large - capacity, which is based on single chip microprocessor and usb interface. it overcomes some shortcomings of traditional devices such as : big size, short work time, small memory capacity etc. it also has many advantages of high speed, low power dissipation, ease - of - use, ease to expand port, supporting plug - play, low - cost etc, so it will be used very widely
在飛機的飛行試驗中，海量數據的採集、存儲和傳輸一直是系統非常重要的一部分，尤其是對飛行員駕駛艙環境控制系統的溫度、壓力等參數的測量來說更是如此。本文根據課題實際需要，研製的基於單片機和usb介面的多通道、大容量、便攜式數據採集系統，克服了現有設備體積大、工作時間短、存儲容量小等缺點。同時，本系統還具有功耗低、速度快、使用方便靈活、易於擴展、支持即插即用、成本低廉等一系列優點，具有廣泛的應用前景。 -
At the same time, due to the drastic competition between the coast ports of china, how to reduce the cost of operation and explore new cargo for loading and discharging is the most important target, and the great need of chemical raw material give them the chance to build new berth and storage area for chemical operation to make the new improvement in economy. unfortunately due to the poor management and the low technology, the speed of the development is lower
同時目前國內各大港口均面臨著激烈的競爭，因此如何降低裝卸成本和開辟新的貨源成為港口生產的當務之急，而液化品需求量的快速增長為港口的發展提供了新的機遇，許多港口紛紛興建化工專用泊位或開辟化工裝卸作業區，以尋求新的經濟增長點，但由於技術和管理方面的原因，發展一直較為緩慢。 -
Now, the storage area network ( san ) is one of the mainstream storage technologies. the san has many outstanding characteristics : high speed, high availability, high expansibility, cross - platform sharing, remote virtual storage and low tco, etc. it provides a genuine solution for the concentrative storing and management of the vast data. the data storage system of most large enterprises uses the san
目前， san （ storageareanetwork ）是主流的存儲技術之一， san具有高速度、高可用性、高可擴展性、跨平臺、較低的總體擁有成本（ tco ） 、遠程虛擬存儲等特性，為海量數據的存儲和管理提供了一個真正的集中式存儲解決方案，大型企業的數據存儲系統大多是採用san技術。 -
For above purpose, we must synchronously and constantly acquire several signals, such as stator voltages, stator currents, rotor speed of asynchronous motor and so on, and synchronously save, dynamically display, fully analyze and process the acquired signals. apparently, the traditional measuring instruments ca n ' t satisfy these special requirements. if the digital storage oscilloscope is adopted to record data, it ca n ' t resolve two problems : the low storage capacity and the poor data analysis and process
為了達到上述目的，需要同步、長時間地採集異步電機端部電壓信號、電流信號、電機轉速等多路信號，並對採得的信號進行實時存儲、動態回放和分析處理，採用傳統測量儀器已經不能滿足這些要求，採用數字存儲示波器記錄數據，存在存儲深度不夠及數據分析處理的問題。
