LVDS和M-LVDS電路實(shí)施指南

低電壓差分信號(hào)(LVDS)是一種高速點(diǎn)到點(diǎn)應(yīng)用通信標(biāo)準(zhǔn)。多點(diǎn)LVDS (M-LVDS)則是一種面向多點(diǎn)應(yīng)用的類(lèi)似標(biāo)準(zhǔn)。LVDS和M-LVDS均使用差分信號(hào)，通過(guò)這種雙線式通信方法，接收器將根據(jù)兩個(gè)互補(bǔ)電信號(hào)之間的電壓差檢測(cè)數(shù)據(jù)。這樣能夠極大地改善噪聲抗擾度，并將噪聲輻射降至最低。

基于GA與L-M優(yōu)化算法的變壓器故障診斷研究

利用MATLAB環(huán)境建立一個(gè)用于變壓器故障診斷的ＢＰ網(wǎng)絡(luò)模型。首先利用具有全局尋優(yōu)功能的遺傳算法對(duì)BP神經(jīng)網(wǎng)絡(luò)的初始權(quán)值和閾值進(jìn)行優(yōu)化，然后采用L-M（Levenberg-Marquardt）優(yōu)化算法對(duì)BP神經(jīng)網(wǎng)絡(luò)進(jìn)行訓(xùn)練，從而達(dá)到加快網(wǎng)絡(luò)訓(xùn)練速度，避免訓(xùn)練過(guò)程陷入局部極小點(diǎn)的目的。最后，詳細(xì)記錄網(wǎng)絡(luò)的實(shí)際輸出，并與期望輸出做對(duì)比研究，最終證實(shí)了此網(wǎng)絡(luò)達(dá)到了設(shè)計(jì)要求，可用于變壓器的故障診斷。

100-15V TO 12V DCDC 原理圖 PCB BOM表

高的工作電壓高達(dá)100V N雙N溝道MOSFET同步驅(qū)動(dòng) The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSFET. When in regulation, power is derived from the output for higher effi ciency.

電網(wǎng)現(xiàn)場(chǎng)作業(yè)管理系統(tǒng)的信息化設(shè)計(jì)

為了改變目前電網(wǎng)現(xiàn)場(chǎng)作業(yè)管理的變電巡檢、變電檢修試驗(yàn)、輸電線路巡檢檢修等管理系統(tǒng)各自獨(dú)立運(yùn)行，信息不能共享，功能、效率受限，建設(shè)和維護(hù)成本高的現(xiàn)狀，提出了采用B/S+C/S構(gòu)架模式，將各現(xiàn)場(chǎng)作業(yè)管理模塊和生產(chǎn)MIS（管理系統(tǒng)）集成為一體的現(xiàn)場(chǎng)作業(yè)管理系統(tǒng)的設(shè)計(jì)方案，做到各子系統(tǒng)和生產(chǎn)MIS軟硬資源共享，做到同一數(shù)據(jù)唯一入口、一處錄入多處使用。各子系統(tǒng)設(shè)備人員等基礎(chǔ)信息來(lái)源于生產(chǎn)管理系統(tǒng)，各子系統(tǒng)又是生產(chǎn)管理系統(tǒng)的作業(yè)數(shù)據(jù)、缺陷信息的重要來(lái)源。經(jīng)過(guò)研究試用成功和推廣應(yīng)用，目前該系統(tǒng)已在江西電網(wǎng)220 kV及以上變電站全面應(yīng)用。 Abstract: In order to improve the status that the substation field inspection system， substation equipments maintenance and testing system， power-line inspection and maintenance system are running independent with each other. They can?蒺t share the resource information which accordingly constrains their functions and efficiency， and their construction and maintenance costs are high. This paper introduces a field standardized work management system based on B/S+C/S mode， integrating all field work management systems based on MIS and share the equipments and employee?蒺s data of MIS，the field work data of the sub systems are the source information of MIS， by which the same single data resouce with one-time input can be utilized in multiple places. After the research and testing， this system is triumphantly using in all 220kV and above substations in Jiangxi grid.
