每個電子密碼鎖都能獨立完成門狀態(tài)和鎖狀態(tài)的監(jiān)控、識別卡是否有效、實時監(jiān)控刷卡 動作、控制電子密碼鎖和報警器、讀取鍵盤信息等一系列的操作。電子密碼鎖系統(tǒng)的硬件部 分主要包括射頻基站MFRC530、鍵盤輸入模塊、LCD 液晶顯示、監(jiān)測控制模塊、RS485 通 信接口、時鐘DS1305、信息存儲單元及蜂鳴器報警。電路的硬件框圖如圖2所示：
圖2 電子密碼鎖系統(tǒng)組成
（1）系統(tǒng)采用單片機STC89C58RD+作為控制芯片，它是電子密碼鎖系統(tǒng)的控制核心， 用來控制并協(xié)調(diào)處理電子密碼鎖系統(tǒng)的數(shù)據(jù)信息。STC89C58RD+內(nèi)置32K 的Flash 存儲器 和1280 字節(jié)RAM，具有3 個16 位計數(shù)器和一個標準的串行通信口，并具有P4 口、加密 性強、超強的抗干擾性、超低功耗、在線系統(tǒng)可編程和可遠程升級等優(yōu)點。
（2）射頻基站模塊采用了飛利浦公司的MFRC530 芯片，MFRC530 是與射頻卡實現(xiàn)無 線通信的核心模塊。它根據(jù)寄存器的設(shè)定對發(fā)送緩沖區(qū)中的數(shù)據(jù)進行調(diào)制得到發(fā)送的信號， 通過由TX1，TX2 腳驅(qū)動的天線以電磁波的形式發(fā)出去，非接觸式IC 卡采用RF 場的負載 調(diào)制進行響應。天線拾取非接觸式IC 卡的響應信號經(jīng)過天線匹配電路送到RX 腳，MFRC530 內(nèi)部接收緩沖器對信號進行檢測和解調(diào)并根據(jù)寄存器的設(shè)定進行處理。處理后的數(shù)據(jù)發(fā)送到 數(shù)據(jù)總線待MCU 讀取。MCU 與MFRC530 采用SPI 總線方式進行通訊，可實現(xiàn)與非接 觸式IC 卡數(shù)據(jù)的無線傳輸。
（3）信息存儲單元主要用來存儲用戶的交互信息，并防止出現(xiàn)網(wǎng)絡故障時，影響電子 密碼鎖的正常使用，從而實現(xiàn)電子密碼鎖的隔離性。存儲單元的用戶信息和服務器數(shù)據(jù)庫信 息要求一致。信息存儲單元采用Ramtrom 公司生產(chǎn)的一種鐵電存貯器（FRAM） FM38081，存 儲容量為32k×8bits 的新型FRAM，具有高速讀寫、超低功耗和無限次讀寫等特性，特別適 合那些對數(shù)據(jù)采集、寫入時間要求很高的場合。由于MCU 不具有IIC 總線接口，F(xiàn)M38081 與外部接口需要采用工業(yè)標準IIC 總線，因此本系統(tǒng)采用P2.3 和P2.4 口線來模擬IIC 總線。
（4）系統(tǒng)在刷卡時需要記錄刷卡的時間，通過采用美國DALLAS 公司推出的低功耗串 行通信接口專用芯片DS1305 來提供一個準確可靠的時鐘。DS1305 支持通過SPI 串行數(shù)據(jù) 端口或標準的三線接口進行時間的校正和數(shù)據(jù)的讀取，可進行單字節(jié)的連讀字節(jié)束發(fā)方式的 訪問。在本系統(tǒng)中，采用SERMODE 接地、使用三線串行方式與單片機進行數(shù)據(jù)通信：SCLK 作為時鐘輸入，SDA 作為串行數(shù)據(jù)輸入和輸出，RST 作為通訊允許信號。
（5）檢測控制模塊主要是實時監(jiān)測門、鎖狀態(tài)和通訊的狀態(tài)，并執(zhí)行控制器的各種控 制信息，如執(zhí)行、執(zhí)行報警等；LCD 液晶顯示部分選用以ST7920 為控制器的128×64 帶漢字庫的液晶模塊，用以顯示時間日期及各種狀態(tài)信息，作為人機交互的界面；鍵盤輸入 模塊采用4*4 鍵盤輸入，主要為MCU 提供用戶的輸入信息；蜂鳴器報警部分則為電子密碼 鎖的錯誤狀態(tài)發(fā)出報警的聲音。
