  • 智能電表和智能電網手冊

    Abstract: Investment in smart meters and smart grid end equipment continues to grow worldwide as countriestry to make their electric delivery systems more efficient. However, as critical as the electric deliveryinfrastructure is, it is normally not secured and thus subject to attack. This article describes the concept oflife-cycle security—the idea that EMbedded equipment in the smart grid must have security designed into theentire life of the product, even back to the contract manufacturer. We also talk about how life-cycle securityapplies to EMbedded equipment in the smart grid. Potential threats are discussed, as are potential solutionsto mitigate the risks posed by those threats.

  • PICmicro中檔單片機系列參考手冊(中文資料)

    Microchip 公司是 The EMbedded Control Solutions Company® (嵌入式控制系統解決方案公 司) ,其產品主要滿足嵌入式控制市場的需求。我們是以下產品的領先供應商: • 8 位通用單片機(PICmicro® 單片機) • 專用和標準的非易失性存儲器件 • 安防器件 (KEELOQ®) • 專用標準產品 欲獲得您所感興趣的產品列表,請申請一份Microchip產品線目錄。該文獻可從各地的Microchip 銷售辦事處獲得,或者直接從Microchip的網站上下載。 以往,8位單片機的用戶只選擇傳統的MCU類型,即ROM器件,用于生產。Microchip率先改變 了這種傳統觀念,向人們展示了 OTP(一次性編程)器件比 ROM 器件在其壽命周期內具有更低 的產品成本。 Microchip具備EPROM技術優勢, 從而使EPROM成為PICmicro 單片機程序存儲器的不二選擇。 Microchip 盡可能地縮小了EPROM 和ROM 存儲器技術之間的成本差距,并使顧客從中受益。其 他MCU供應商無法作到這一點,這從他們的 EPROM 和 ROM 版本之間的價格差異便可以看出。 Microchip的8位單片機市場份額的增長證明了PICmicro® 單片機能夠滿足大多數人的需要。 這也 使 PICmicro 單片機架構成為了當今通用市場上應用最廣泛的三大體系之一。Microchip 的低成本 OTP解決方案所帶來的效益是這一增長的助推劑。用戶能夠從以下各方面受益:  • 快速的產品上市時間 • 允許生產過程中對產品進行代碼修改 • 無需掩膜產品所需的一次性工程費用(NRE) • 能夠輕松為產品進行連續編號 • 無需額外增加硬件即可存儲校準數據 • 可最大限度地增加PICmicro® 單片機的庫存 • 由于在開發和生產中使用同一器件,從而降低了風險 Microchip 的 8 位 PICmicro單片機具備很好的性價比,可成為任何傳統的 8 位應用和某些 4 位應 用(低檔系列)、專用邏輯的替代品以及低端DSP應用(高檔系列)的選擇。這些特點及其良好的 性價比使PICmicro單片機在大多數應用場合極具吸引力。

Based on the digital signal, the MCU PIC16C71 drived the valve by a DC motor to adjust the water temperature through adjusting the proportion of hot water and cold water.The circuit diagram of controller was given,the principle,the component parameters and the accuracy of measuring temperatures were also dissertated in detail. It was found by experiment and analysis that thermal breakdown of thermistor caused by high power could be solved by selecting thermistor and fixed resistance with high impedance value.
