• Cyber​​ ——the of ,,那什麼是咱們需要關注的這個BAS,也就是自動化系統網絡安全方面的事, 我就想著,在真正展開說之前很多人對еcuгity in BAS,其實心裡都還是有點懵懂。那,就好比建築的神經系統,控制著從照明——就是那些燈明不亮的事;HVAC;還有其它各種設施系統各種自動化運行的方方面面,這麼一比喻應該好理解些……

    那第一個很重要的部分,就是得對系統組件有個徹徹底底的曉得,我就講講主要要點。

    要知道自動化系統有一堆小零碎,像是傳感器啊(採集環境吶什麼數據那種,溫度,濕度啦);控制設備例如DDC(可編程邏輯控制器啥的都這裡邊這個功能不同設備);還有——這通訊網絡等等。咱拿傳感器來說,它可不是簡單一物件兒。不同類型就起不同作用。紅外的能監測物體接近與否;這個溫度的曉得室內暖啊冷啊各方面。這個東西有精度,所以一個高精度精準去採集溫度傳感器比低精度來說,就可容易反饋準確現場溫度。通訊網絡上TCP / IP用與它別的之間也就存在差異,像是以太網絡相比工業總線——就是像這種的網絡那種安裝成本貴好多呀但是適用環境,可靠性什麼都不同……。這個里面設備互相交互通過不同協議彼此協調工作嘞?

    接著這打漏洞或者說弱點檢測這一環可疏忽不得。這弱點就好比一堵牆上的缺口。系統弱點掃描其實就是專門檢查軟件或者像某些防護策略之類的地方存在沒有解決的各種漏洞。像是很多常見自動化系統存在弱密碼這個通病!很多——默認密碼在安裝的時候沒有啥沒替換。有的系統它老舊呀就沒用像最新的安全更新補丁,就被漏洞“鑽空子”。這裡,基於的像殺毒和這種分析法兒有著差異。簽名——檢測得根據那已知去掃描潛在惡意行為什麼的,但對新的zero day這種沒有的攻擊來說就沒辦法。但異常分析嘛…… 根據正常行為模型識別異常情況,可以識別Zero-day也可以識別,但很有可能存在誤判呀?

    另外咱還得提及系統配置調整這一塊嘍。就講講系統不同組件。不同角色需要訪問權限不同那就是概念。比如維護人員嘛就是能讀設備工況和控制一小部分維護機器用;高層次管理員有可能擁有更多權限。這裡正確配置呢能防止沒權限隨便訪問內部重要信息。不同訪問模式有著, 比如說——遠程允許人員不同之地遠程控制BAS系統,如果隧道沒搞好哦遠程是容易遭受中間人這種很嚴重! 如果相比直接內部連接在本地網段,那本身有安全專網,入侵防禦在正常就好很多,如果沒有外來違規IP進入—— ,local模式受威脅很小。不同訪問策略各有利弊,就需要咱們小心謹慎!

    說到現在講的其實還不算完整,咱們下面通過幾個問答呀進一步細挖一下細節:

    首先有人可能要問吶“如何得知當前BAS的某一設備究竟支持何種的協議呃” 其實解決起來也不太難就是查設備自帶說明或者聯繫供應商,大部分都會有著記錄這設備一些重要相關細節(這裡也是為啥採購要知名好供應商)啥啥那不同設備真不同支持——

    另外常常疑問“能否不同品牌BAS的控制設備互聯互通呢” ?答案嘛是多數可以,但呀往往互操作性有風險,就拿協議被設計嘛主要是不同建築自動化設備通訊嘛允許交互通訊——但品牌之間小細節參數調整不好容易“通信不暢”造成通訊故障

    其次常常討論一個擔憂之處“在遭受在入侵之後怎麼恢復恢復設備工作啊” ?假如係統入侵嚴重完全掛掉話就按照還原步驟從備份恢復,不過有可能入侵早已更改裡面代碼,這時需專業技術人員重新手動核查一遍全部代碼庫哦如果部分設備不正常運行呀也是需要挨個問題排查——

    又有人想到“系統更新過程影響嗎” 多數情況有專門系統更新測試方案,如果沒良好pre-預先制定一套計劃來就經常發生更新出大問題! 新升級可能破壞和原有配置平衡引起不穩定狀況。這裡可以用仿真環境去跑個流程驗證升級好不好先如果沒有問題”OK“真正實施到真實係統” —

    我覺得,對的網絡安全,得步步精心。各環節裡頭又有好多門道。所以方方面面全都顧慮周全,不然這系統運轉就容易出岔子!咱得時刻緊繃著這根弦! !

  • 咱得說說那個“Smart city Abu Dhabi”,也就是阿布扎比的智慧城市基礎設施。咱要先講明白這個詞兒呢?這所謂的智慧城市基礎設施。簡單來說,就是藉助先進的技術手段,讓阿布扎比這座城市的各種系統,從交通、能源再到公共服務等等,都變得更為智能、高效還能環保。

    下面咱來看看這些關鍵的內容分塊

    在交通系統這一塊兒是相當厲害呢。這個,人家通過一系列聰明的辦法完善起來的。

    其一,裝上了好多智能交通傳感器,被安放在道路的各個關鍵地方。這些傳感器就像城市交通的“小眼睛”一樣,它們不間斷觀察著路上車流量是啥狀況,車輛的行駛速度快慢程度怎麼樣,還有不同車道車子分佈多不多諸如此類。通過收集數據,並適時傳輸回控制中心,中心憑藉這些信息就能合理調配信號燈時長。舉例下如果傳感器發現,某一路段車流量變得非常大,都出現擁堵的跡象時,控制中心便果斷延長該路段綠燈亮燈時長,把更多的路權給密集出行區域,從而保障整體交通流暢運行

    然後呢,除傳統交通之外,阿布扎比可是大力推行智能公共交通方面項目。你看,好多公交亭變成高科技載體了,配備了電子顯示屏。顯示屏像個小新聞播報員似地,向等車的人實時提供各路車次預計到達時間,告訴大夥這趟公交還有多遠,都路過哪些站台這樣的信息等等。

    接著在能源管理這一塊?那智慧的程度咱也是得說一說。它可是把能源網搞成智能樣式了嗷!那些遍布各處的智能電錶也好、水錶也好就像小小管家,對每一點能源的消耗事無鉅細記錄下來,再快馬加鞭般回傳給監控中心。工作人員便據此來對哪些地方高能耗一目了然嗷。

    比如說像是一些大型商廈,如果用電量在特定時段超級高,就能進一步找到是商廈哪幾個板塊能耗過度,比如空調負載過大,照明消耗不合理這類原因進而通過調節商廈一些設備運作參數來調整用電量。另外,阿布扎比還搞了許多儲能設施,以防止電力供應異常情況發生之類了等等!

    再看看信息通信基礎設施哈。遍布全市範圍內的高速寬帶網絡以及超厲害的5G 基站;各個園區各個寫字樓從早到晚都穩穩有網,大家可以不管白天黑夜上網辦業務跟世界聯繫。而且呢這麼強的通信基礎支持城市好多好多監控攝像頭正常運作了!這個意味著啥,攝像頭“犀利目光”遍及各種重點區域,把信息飛快傳遞回來,處理治安情況更加快速高效多

    下面用問答形式說些細節:

    問:這麼做智能基礎設施一定花費很大嗎?

    答:的確是不小但長遠來講省錢又省事。它雖然前期投入不小,不過運用這基礎設施後,能源浪費被大大降低,各個方面的效率都快翻天反而能把成本啥的逐年降下來的嗷!

    問:這能給普通居民帶去啥具體好處呢?

    答:平常生活變得方便太多咯。出行上交通不容易堵。而且通過好多手機APP,水電燃氣這些家用繳費全在自家指頭上操作就能搞定。還有像政務方面有的各種線上預約線上諮詢都好使喚得很。

    咱們得明白建設這樣一套好東西,讓城市像是升級好多級。政府部門之間能夠因為這般先進設施快速信息共享辦公加速推進各類複雜事務進程。居民和那些商事公司呢也因為這日子便利又舒坦還更有創意,真的給城市裝上科技的翅膀讓生活方方面面迎來改變耶!

  • DDC ( ),也就是說直接數字控制控制器啦的時候很多人不清楚是咋回事的。簡單講,這個,那可是個比較關鍵的設備東西,用於自動化控制領域這邊很廣的。你瞧啊直接數字控– 或者說,這個DDC 控制器的存在,直接可就把模擬控制給替換了不少這樣子。這個是非常大的變化。

    在技​​術這塊兒呀的話

    1.精準控制:它能夠實現精確又精密的數據處理以及控制任務。能非常精準把控各項參數對比過去,在處理數據方面可謂極其嚴謹以前可沒想到能做到如此細緻對比。

    2.靈活性:靈活性真是超高很多老舊的控制方式吧靈活性那真是差得遠的。你可以方便輕鬆修改編程改變控制流程和方式啊而且只要修改一下軟件呀什麼相關設置得,就能夠應對各種不同場景!改變不同設定所以相當便利。這在很多實際安裝裡表現明顯的。

    1.規劃位置:誒首先呢哦位置這一個點呀嗯不得不提到一下哦對啦很重要注意通風良好的地方必須得是。避免潮濕啊這些壞境影響性能。可別安在意位置隨意位置弄錯控制器出問題故障可麻煩咯就這很實際中發現常常犯錯之處。再則也要盡量遠離強電磁場,別受到干擾干擾影響穩定性這塊兒。

    2.佈線規範:這個線路啊得整規範嘍規範整齊!不同類型線路都要認真區分一下區分類型像強弱電線路不要搞混然後佈線得注意美觀更得重視安全性注意安全保障這個佈線影響不僅系統性能以後維修檢查什麼方便還是一個重點方便維修的

    一些實用問答

    1. “能用很久嗎”,這東西一般情況下使用的使用年限可不少正常穩定使用個十幾年吧常見一般。但是,使用得注意環境溫度以及濕度呀影響不然老是高熱高濕環境內部部件損耗加快那麼使用壽命也被影響嘍就。也還是有差異的。

    2. “裝起來麻煩嗎” 要是有著足夠經驗技術員操作來說呀算不上太煩不過初次接觸安裝的話按圖來說明書結合經驗摸索可能時間花多點並且要非常了解細節的。有些小設置地方得斟酌考慮好久這個小麻煩嘛有。

    在這個數字時代裡邊兒嘞呢

    這DDC 個控制器哇可不得了

    很多領域建設領域也多用這個DDC 控制好系統整個好管理監控系統狀態的

    發揮獨特且非常關鍵作用關鍵不可獲取的以後用使用前景肯定更為廣闊更為廣泛廣泛得多,會不斷升級帶來優勢好處唄實實在在好處。

  • 嘿咱們這次聊這個“ value stats”是什麼呢其實啊就是有關房產價值增長數據這麼個事這數據可不簡單吶在咱們生活裡面非常有用

    這房產價值增長數據可以說是反映咱們一個地區房地產狀況的呢它可不是單一的啦涉及各方面情況的喲

    下面我給分多個內容來說說它咱們想要用這個來考量一些決策啥的時候這些點千萬得要記住的喲

    1. 不同區域的價值增長數據

    首先咱們不能一鍋燉來看待這些區域不一樣啦房產價值增長勢頭相差可大比如說那種繁華大都市裡面的中心地段的房源的咯在人流量超大的商業地帶配套又超全乎的地方這種地帶呢人口流入往往很大然後房子需求也大在這個經濟很蓬勃發展商業聚集的一塊房子價值他要是說他能夠在一年內增長個百分十幾左右其實屬於一種比較樂觀的一個區間咯

    2. 房屋情況對於價值增長率的影響

    如果說是新房和老房子還不一樣啦新房哇剛建設好那種嶄新嶄新的外觀設計、裝修好有那種獨特還有配套設施新科技什麼的剛出的房子那可和舊房子是完全屬於天差地別的兩個狀態剛推出市場特別有吸引力的新品一年裡價值在本來價格之上再能夠提升個百分之七八也是挺常見的一件事情

    可是嘞如果說是老房子哇已經建成多年很有歲月的滄桑感這些房子建築風格上過時啦再或者格局跟不上現代要求要是說他還能上漲主要就只能依托區域、地段頂多他還能增長個百分之三這樣

    3. 利用價值增長數據來買賣決策

    要是咱們作為購房者要是研究這些增長率喲可有用啦比如說在那種目前價值在小範圍波動但從增長率上可以看出它整體趨勢在上升這個區域往往比較合適於買入咱們要長期持有的話

    如果咱們呢作為賣家就反而得找最高峰值這個價格高的時候然後這個增長率也逐漸趨於穩定的時候這個階段出手最為的一個恰當

    那有人可能要問了這不同城市間這種增值數據要咋給整到對比中去

    其實不難咱們只要找那種基礎情況差不多城市發展等級的呀人口流動性質還有經濟體量相差不了好多那種做對比比較穩你看那種都屬於二三線的而且支柱產業都是偏向科技領域這種對比起來就比較有意義可比性就好不像拿那種三線比一線嘛那就完全不可看哇

    那又有人有疑問有沒有快速從這數據看出來哪個地方價值會漲?

    其實主要就在人口增量經濟體量變化的一個趨向如果一個城市最近連續幾年企業入駐很多新開發工業地塊項目非常密集這人流量也是不斷在上升階段的時候根據發展進程嘛這個地方絕對是有著非常巨大的一個房產價值漲幅可能性

    你比如說吧從咱們研究的各數據總體上來看要我說啊大家要是準備入房地產這一潭水里面做買賣或者怎麼樣這房產的數據肯定不可盲目看一個兩個方面是完全都不夠必須全方位了解參考越多各城市地區,不同性質房產的數據將來啊無論是做賣家還是購房者,咱們做這個抉擇才能夠比大多數人做得更穩這樣子選擇才能做得好實實在在不吃虧

  • 在空調控制優化領域這個HVAC到底是什麼東西,咱得來聊一下清楚。 簡稱文化算法——說簡單點,就是拿文化演化規則來解決實際問題思路的一方式。所謂HVAC,邊說邊分析往實裡講也就是把文化算法應用到暖通空調HVAC系統裡頭去優化管理控制。你想,HVAC又是什麼? HVAC它指暖通空調系統——調節室內溫度濕度還有空氣流動等。把文化算法用到這裡頭啥目的呢。目標很單純,節省能耗提升效率罷了,邊唸叨心裡邊有數了咱展開來看看

    首先講講原理層面, 在HVAC過程裡啥步驟的干活——第一步那肯定參數設置環節。設定種群大小,這個文化算法咱要調整好多的參數——初始信念設置開始展開,這些個值啊不同實驗得不同參考——這個還能跟空調性能相互磨合得配合來調。打比方,如果實驗空間相對來說小點,人少少,就跟正常家用似的那種——這參數就得多試試家用空間測試所得參數——要是換作像什麼大型商場等大型空間,這需要重新找最適配於實驗空間和人群多寡來測試參數,還得結合系統響應速度,這樣也便於更準確地預估

    第二步驟說的是初始化群體環節幹活,必須模擬自然種群形式,你想想哈就跟自然裡頭動植物種群那樣——初始化一個HVAC行為種群。一開始這個行為表現比較混亂,相當於新生種群的感覺一樣! 在這樣的行為裡面,存在了不同調節模式!這裡面就存在多種不同調節策略,隨機選取HVAC調節各種策略來定初始的每個個體的調整行為,就比如說有的個體它偏向用最激進耗能低速率模式;有的就按部就班不溫不火地進行固定程序常規速率調節模式、還有追求極限位採用高速冷量調動模式,也不管耗電到底合不合理。然後緊接著講信念空間層面這個又得講講嘞……!按調節空間參數及策略,咱結合先做好策略還有模擬好參數基礎上把不同算法原理運用進其中設置信念空間——這裡融合心理學裡頭社會意識指導之類原理往空間裡頭設置不同“規範”,拿準則去調整裡面群體成員啦!這信念裡設置出權威規則以及群體共識哈!

    好,還有算法性能對比上! 相比於傳統空調單純溫度、壓力傳感器依賴,來做固定標準範圍反饋調節—— HVAC好在利用算法自動尋優不斷優化!傳統基於模型控制模式,參數變化困難適應不了現場情況復雜地方! 動態調整特性那可方便多了!但傳統固定程序按程序運行可不行!如果外部溫度忽然急劇升高許多——傳統程序就不大靈光難變招了! HVAC卻靠著文化算法自動調整內部行為適應能力變強好多。那HVAC是不是一定完美了!其實它也不夠完善處不少! 就是初期這些群體探索行為時候,它會出現一些極端調整行為——這個怎麼解釋了,就是說一下子調的過高或是過低。但是跟傳統的HVAC系統相比之下可好多了!

    這裡面提一些有了關於HVAC 里大家比較多能問點小問題解答解答哈。首先是不是不同結構系統都能用這種,準確來講得具體結合調試應用!工業性質系統比如大型冷庫之類調溫特點往往恆溫等。家里普通別墅和平層調溫特點不同——大型辦公樓人群有集中性所以這個所優化方向也是各種各樣不同

    怎麼準確選這裡面參數設置好?一般參數也需要一些基於經驗設置比如跟室內場所類型相關不同參考,再然後必須進行多次模擬實驗了,按照模擬數據去優化改變裡頭參數,多實驗多實踐。結合實驗場景以及後續維護等全面因素裡頭判斷這參數最好的效果究竟是設在哪檔,當然我說再強調一下以上也是我的個人觀點,僅供您多一種思路參考!

  • MQTT,這可是一塊在遺留系統集成領域當中,特別重要的技術。對於MQTT進行深入了解以及合理運用的話,它真的是能夠很好地幫助咱們企業把那些舊有的遺留系統跟新的技術或者應用程序整合起來的,特別實用。

    就先說這個MQTT本身,它是一種基於發布/訂閱模式的這種輕量級消息傳輸協議,是專門用於進行遠程監控與數據採集相關場景當中特別適合。 當咱們要集成遺留系統的時候, 像傳統製造業遺留那批監測設備如果想要和新的數據分析平台聯合, MQTT就能起很大作用。不過說起特點,這個簡單又快速的話傳輸特性真心好使,這協議要求的帶寬不高數據能夠快速傳遞,就比如物聯網傳感器採集了工廠的溫濕度相關情況那數據用MQTT能很快傳到後台。而且設計上就是面向低帶寬、還有這種遠距離網絡這麼考慮的,那對於遺留系統可能存在那種通信網絡不好的情況,就完全有應對的一招。同時就說低功耗的這個點而言。能減少物聯網設備用電。這無疑對於依賴部分舊設備實現遠程控制老系統來說特別貼心!

    咱從技術原理角度再來掰開來說說。 MQTT其實用到了發布者、訂閱者,以及兩者之間起到中間人作用的服務器。 發布者發出對應主題消息。訂閱者想要的那個消息匹配就獲取。說起來,像以前遺留工控系統想整合到現系統這邊的時候,發布者把設備狀態消息以主題形式公開釋放消息啦比如“-”,然後應用部分或者接受數據進行分析部門這個, 根據自己想法通過訂閱對應主題拿到信息來實現功能拓展。

    要運用MQTT做好遺留系統集成。頭一步對於現有遺留系統得有一個很全面的認識的。 需要咱們系統管理人員好好整理設備信息,關於有哪些設備、設備功能等清楚記錄。之後,就要考慮創建很完備穩定MQTT服務端呀就包括找到性能適配合適的設備然後安裝專業知名MQTT服務管理器。第三要設置發布者和訂閱者客戶端!這涉及軟件層面如何創建以及保證好網絡配置確保設備、軟件之間有效相互通信嘞再然後涉及很關鍵主題設計部分, 不同類型的數據,對應的消息就合理設計不同主題能極大提高數據通信清晰層次方面的能力!最好一步就要不斷測試多方式交互數據、查看統計分析性能測試後進行對應調試,把不穩定的因素或者不足等全部分處理完成。

    其實,說到這裡咱就聊一下常見問題方面話題。有人會可能想問那在集成的時候遇到格式不對應的情況這個要咋辦。 嗯哼可以用專門MQTT轉換工具先把不同的數據轉換格式

    還有呢就想問設備太多會不會擁堵服務端啊這個擔心蠻實在的。 如果規劃安排正確做動態配置根據設備功能分區管理或者對應智能分配資源。這個就不需要擔憂了~總的來說MQTT進行留系統集成,真是帶來轉變現有不足契機。咱們完全能實現原有資源跟現實需求完美牽手。通過對它有效運用推動老舊系統活力再現!它給相關傳統企業整合過程中不少驚喜表現真值得好好大力推廣用起來去!反正我自己挺看好它發展空間的。 真希望看到越來越多企業能夠因此盤活自己的庫存老舊系統資源,給他們迎來一個新的活力變革時刻!
