解釋
調整訪問控制-
It adopts the xbrothers professional security and facility control system which includes : the real - time monitoring and controlling for the electric power supply system ; the air conditioning control system ; the ups control system ; the leaking control system ; the fire alarm system ; the video surveillance system and ; the access control system. the system provides the fire monitoring and turn to emergency status when fire detects. the system alarms for the abnormal of the important field through adjusting dynamic detecting sensors, according to the demands in the video marking field
在該監控系統中，如果檢測到消防報警信號，系統會自動聯動門禁系統打開對于重要區域的視頻劃定動態檢測報警區域，根據機房內不同的環境情況，通過調節動態檢測靈敏度，來實現移動報警系統採用模塊化結構設計，可以方便的進行系統擴充，在本項目最初實施的過程中只安裝了一套指紋加刷卡的門禁系統，在使用的過程中，根據清算中心的要求，需要對機房內的另四道門加門禁系統，則監控系統在不影響原有系統正常運行的情況下，進行系統的平滑升級，最大化的保障系統的安全與用戶的投資。 -
Simulation is operated with ns2 under linux, and the simulation results show that, the presented algorithm is simpler and more practical, while it can improve the fairness index of ad hoc network to a large extent compared with the ieee802. 11 binary exponential backoff ( beb ) algorithm. it can make better use of the wireless channel by dynamically adjusting its backoff timer according to the network ' s contest situation. in addition, service differentiation can be achieved among flows with different qos requirements and thus the qos for medium access control in ad hoc network is improved
通過在linux系統下利用networksimulator （ ns2 ）模擬工具對演算法進行計算機模擬分析，結果表明，與ieee802 . 11標準採用的二進制指數退避（ beb ）演算法相比，該文所提演算法更簡單、高效，它能在很大程度上提高adhoc網路通道接入的公平性，並能動態地提供服務區分，保障對多媒體等多種實時業務的傳輸需求，同時，演算法可以根據網路當前具體的競爭激烈情況，動態調整退避時間值，從而提高通道的利用率。
