為了使本技術領域的人員更好地理解本說明書中的技術方案，下面將結合本說明書實施例中的圖式，對本說明書實施例中的技術方案進行清楚、完整地描述，顯然，所描述的實施例僅僅是本說明書中的一部分實施例，而不是全部的實施例。基於本說明書中的一個實施例或多個實施例，本發明所屬技術領域中具有通常知識者在沒有做出創造性勞動前提下所獲得的所有其他實施例，都應當屬於本說明書實施例保護的範圍。
本說明書提供的一種實施方案可以應用到計量設備/終端設備/伺服器的系統構架中。所述計量設備可以包括需要讀取自身資料的設備，如水錶、電錶或者燃氣表等。所述計量設備可以包括通訊模組，可以與終端設備透過藍牙或WiFi進行連接和資料傳輸，也可以與遠端的伺服器進行通訊連接，實現與所述伺服器的資料傳輸。所述終端設備可以包括通訊模組，可以與計量設備透過藍牙或WiFi進行連接和資料傳輸，也可以與遠端的伺服器進行通訊連接，實現與所述伺服器的資料傳輸。所述終端設備可以包括行動終端，如智慧型手機或平板電腦等。所述伺服器可以包括單台電腦設備，也可以包括多個伺服器組成的伺服器集群，或者分散式系統的伺服器結構。本說明書實施例中所述的伺服器、計量設備、終端設備包括從邏輯上劃分的不同資訊處理方。
如圖1所示，圖1是本說明書提供的一種資料讀取方法的一個場景示意圖。其中，水錶、電錶或者燃氣表等計量設備以及智慧型手機或平板電腦等終端設備包括藍牙模組，計量設備與終端設備之間可以透過藍牙進行連接和資料傳輸，且該計量設備處於從模式，用來廣播信標資訊。終端設備可以與遠端的伺服器進行通訊連接，從而實現與伺服器的資料傳輸。一些實施場景中，當需要獲取計量設備中的資料時，計量設備可以將自身的計量資料加密後透過藍牙的方式進行廣播，終端設備可以在預設距離範圍內且觸發了指定應用的匹配指令時，建立與計量設備的通訊連接，然後將接收到的信標資訊進行匯總後發送至伺服器，伺服器在接收到匯總資訊後，進行對應的驗證，驗證透過後記錄計量資料。這樣，無需抄表人員肉眼觀測或上門觀測，便可以獲取各個計量設備的計量資料，從而可以保證伺服器記錄的資料的真實性的同時，可以有效解決資料傳輸過程中被惡意篡改的問題，提高資料讀取的安全性。
下面以一個具體的應用場景為例對本說明書實施方案進行說明。具體地，圖2是本說明書提供的所述一種資料讀取方法實施例的流程示意圖。雖然本說明書提供了如下述實施例或圖式所示的方法操作步驟或裝置結構，但基於常規或者無需創造性的勞動在所述方法或裝置中可以包括更多或者部分功能合併後更少的操作步驟或模組單元。在邏輯性上不存在必要因果關係的步驟或結構中，這些步驟的執行順序或裝置的模組結構不限於本說明書實施例或圖式所示的執行順序或模組結構。所述的方法或模組結構的在實際中的裝置、伺服器或終端產品應用時，可以按照實施例或者圖式所示的方法或模組結構進行循序執行或者並存執行(例如並行處理器或者多執行緒處理的環境、甚至包括分散式處理、伺服器集群的實施環境)。
需要說明的是，下述計量設備/終端設備/伺服器交互的實施例描述並不對基於本說明書的其他可擴展到的應用場景中的技術方案構成限制。具體的一種實施例如圖2所示，本說明書提供的一種資料讀取方法的一種實施例中，所述方法可以包括：
S10：獲取計量設備上的計量資料，基於所述計量資料、識別標識以及第一時間戳產生第一加密資料，所述第一時間戳包括計量設備獲取所述計量資料時所對應的時間。
所述計量設備可以包括需要讀取自身資料的設備，如水錶、電錶或者燃氣表等。所述計量設備可以包括通訊模組，可以與終端設備透過藍牙或WiFi進行連接和資料傳輸，也可以與遠端的伺服器進行通訊連接，實現與所述伺服器的資料傳輸。所述計量資料包括所述計量設備上需要讀取的資料，如用水量、用電度數、所用燃氣量等。所述識別標識可以包括用來區分不同設備的標識(以下可以簡稱為“設備唯一標識”)、設備編號等。時間戳可以唯一標識某一刻的時間。所述第一時間戳可以包括計量設備獲取計量資料時所對應的時間。需要說明的是，同一設備的設備唯一標識可以保持不變，設備編號可以更改。
本說明書一個實施例中，所述計量設備可以包括廣播韌體、加密模組以及資料讀取模組。其中，所述資料讀取模組可以用來獲取計量設備當前資料(如，計量資料、時間戳等)。所述加密模組可以用來對所述資料模組讀取的資料進行加密處理。所述廣播韌體可以用來對所述加密模組處理後的資料進行廣播，所述廣播韌體可以是BLE (Bluetooth Low Energy，藍牙低能耗)廣播韌體或者WiFi韌體等。所述加密處理演算法可以包括一次性密碼(One-time Password，OTP)演算法、基於散列消息身分驗證碼(Hashed Message Authentication Code，HMAC)演算法加密的一次性密碼(HMAC-based One-Time Password，HOTP)演算法等。一些實施場景中，OTP、HOTP等演算法可以根據專門的演算法每隔一段時間產生一個與時間相關的、不可預測的亂數字組合，每個口令只能使用一次。一些實施場景中，OTP、HOTP可以包括時間視窗機制，透過OTP、HOTP進行加密後的資訊，在預設時間段內有效，超過預設時間段失效。
需要說明的是，一些實施場景中，計量資料可以透過計量設備包括的資料讀取模組獲取，還可以透過智能晶片獲取，也可以透過安裝有智能晶片的計量設備獲取，還可以透過其他方式獲取。本說明書實施例以及圖式中以計量設備獲取自身計量資料為例進行示意性說明，其它方式類似，對此不作贅述。
本說明書實施例中，為了安全有效地將計量設備的計量資料提供給上述伺服器，以便伺服器準確地記錄計量資料，並根據記錄的計量資料準確統計各戶業主家的用度情況，每個計量設備可以分別讀取自身的計量資料，然後根據自身的識別標識中包括的設備唯一標識、計量資料和讀取計量資料時所對應的時間，產生對應的加密資料。
一些實施場景中，所述計量設備可以為電錶。例如，在一個社區的某棟樓裡有多戶業主，每戶業主家分別對應一個電錶，該電錶包括BLE廣播韌體、OTP加密模組以及資料讀取模組。當工作人員需要獲取當前電錶資料時，工作人員可以在計量設備預設距離範圍內觸發行動終端上指定應用的匹配指令向電錶發送獲取當前電錶資料的請求，電錶收到該請求後，可以透過資料讀取模組獲取當前電錶讀數和對應時間，然後透過OTP加密模組將電錶讀數、電錶的唯一標識以及對應時間產生第一加密資料。由於在產生對應的第一加密資料時，所依據的電錶資料是直接讀取的，所以可以保證該電錶資料是真實的。
需要說明的是，由於所述信標資訊的識別標識中不僅可以包括用來區分不同設備的唯一標識，而且也可以包括設備編號。所以一些實施例中，為了防止傳輸資料被惡意篡改、保證傳輸資料的安全性，計量設備對獲取的資料進行加密處理時，可以使用識別標識中包括的設備的唯一標識。一些實施場景中，計量設備、終端設備、伺服器之間可以進行即時通訊，這樣，在計量設備獲取計量資料時，終端設備和伺服器可以獲取對應的時間並保存。需要說明的是，終端設備和伺服器獲取對應時間可以透過本領域人員知曉的任意一種方式，本說明書對此不作限定。
S12：所述計量設備發送信標資訊至終端設備，所述信標資訊包括所述計量資料、所述第一加密資料以及所述識別標識。
所述識別標識可以包括設備唯一標識、設備編號等。
本說明書一個實施例中，所述計量設備在產生各自對應的第一加密資料之後，可以透過自帶的藍牙或者WiFi網路將計量資料、加密資料以及識別標識廣播出去。
本說明書一個實施例中，所述計量設備發送信標資訊至終端設備可以包括：所述終端設備在計量設備預設距離範圍內和/或基於觸發終端上指定應用的匹配指令時，建立所述計量設備與所述終端設備的通訊連接；所述計量設備將所述信標資訊發送至所述終端設備。所述計量設備與所述終端設備建立通訊連接的條件可以包括終端設備在計量設備預設距離範圍內或觸發了終端設備上指定應用的匹配指令或終端設備在計量設備預設距離範圍內且觸發了終端上指定應用的匹配指令等。需要說明的是，建立通訊連接的條件還可以包括其他條件，本說明書對此不作限定。
例如一個實施場景中，抄表工作人員可以啟動所使用的智慧型手機上的計量應用程式(Application，app)，然後透過點擊該計量app上的“資料接收”控制項與計量設備建立通訊連接，從而可以接收計量設備廣播的資訊。另一個實施場景中，抄表工作人員可以在計量設備預設距離範圍內啟動所使用的智慧型手機上的計量app，然後點擊該計量app上的“資料接收”控制項與計量設備建立通訊連接，從而可以接收計量設備廣播的資訊。
一些實施例中，終端設備在接收到計量資料、加密資料以及識別標識後，可以對接收到的資訊進行匯總。例如，抄表工作人員啟動所使用的智慧型手機上的計量app，並點擊該計量app上的“資料接收”控制項與計量設備建立通訊連接並接收到各個計量設備廣播的資訊後，可以將接收到的資訊進行匯總。例如一些實施場景中，終端設備在接收到計量資料、加密資料以及識別標識後，可以按照時間區間進行匯總，也可以按照計量設備對應的位置資訊進行匯總，還可以按照數量進行匯總等。例如，終端設備在接收到計量資料、加密資料以及識別標識後，可以將屬於同一個社區的資訊進行匯總，也可以當接收到的資訊滿100個時匯總一次，還可以將一周內接收到的資訊進行匯總等。
需要說明的是，由於所述信標資訊的識別標識中不僅可以包括用來區分不同設備的唯一標識，而且也可以包括設備編號等。所以一些實施例中，為了防止傳輸資料被惡意篡改、保證傳輸資料的安全性，計量設備在進行廣播時，所述信標資訊中包括的識別標識是設備編號。此外，上述計量設備進行廣播的資訊包括計量資料、第一加密資料以及設備編號只是進行示例性說明，所述計量設備進行廣播的資訊還可以包括其他資訊，本說明書對此不做限定。
S20：所述終端設備將所述信標資訊發送至伺服器。
本說明書一個實施例中，計量設備發送信標資訊至終端設備後，所述終端設備可以將所述信標資訊進行匯總後發送至伺服器。一些實施例中，終端設備可以在達到預設的發送要求時，將所述信標資訊發送至伺服器。所述預設的發送要求可以包括終端設備接收到的信標資訊的數量達到預設數量，或者終端設備接收到一個向伺服器發送一個，或者終端設備對所有信標資訊校驗通過後才發送，或者是定時發送，如一個小時發一次等。
本說明書一個實施例中，所述終端設備可以為行動終端，對應地，所述將所述信標資訊發送至終端設備，所述終端設備將所述信標資訊發送至伺服器可以包括：所述行動終端在計量設備預設距離範圍內和/或基於觸發行動終端上指定應用的匹配指令時，建立所述計量設備與所述行動終端的通訊連接；所述計量設備將所述信標資訊發送至所述行動終端；所述行動終端在達到預設的發送要求時，將所述信標資訊發送至伺服器。
一些實施例中，當所述終端設備接收到的資訊包括計量資料、第一加密資料以及識別標識中的設備編號時，所述終端設備可以將接收到的資訊按照設備編號進行匯總後發送至伺服器。
本說明書提供的另一個實施例中，所述終端設備可以預先儲存上述各個計量設備的相關資訊，如識別標識，其中預先儲存的識別標識中的設備編號與設備唯一標識可以預先設置為相互關聯。所述終端設備在接收到所述信標資訊後，還可以包括：
S200：基於所述計量資料、識別標識以及接收到所述信標資訊時對應的第三時間戳產生第三加密資料；
S202：比較所述第三加密資料與所述第一加密資料，在比較結果符合記錄要求時記錄所述計量資料。
一些實施例中，所述信標資訊可以包括所述計量資料、所述第一加密資料以及所述識別標識。另一些實施例中，所述信標資訊中除了可以包括計量資料、第一加密資料以及識別標識外，還可以包括其他資訊，如第三加密資料。一些實施例中，符合記錄要求可以包括比較結果在預設誤差範圍內，或者比較結果相同，或者其它等。
為了提高資料傳輸的安全性，在一些實施例中，當所述終端設備接收到的資訊包括計量資料、第一加密資料以及識別標識中的設備編號時，所述終端設備可以在預先儲存的資訊中查找與所述設備編號對應的設備，並獲取該設備的唯一標識，透過加密方法對計量資料、設備的唯一標識以及接收到所述信標資訊時對應的第三時間戳進行加密，獲得第三加密資訊，然後終端設備將第三加密資料與第一加密資料進行比較，在比較結果符合記錄要求時，表明接收到的該計量設備的計量資料與產生第一加密資料時所依據的計量資料相同，從而可以表明接收到的該計量設備的計量資料是真實的，最後可以將計量資料、識別標識、第一加密資料發送至伺服器，從而提高資料傳輸的安全性。
另一些實施例中，當所述終端設備接收到的資訊包括計量資料、第一加密資料以及識別標識中的設備編號時，所述終端設備可以在預先儲存的資訊中查找與所述設備編號對應的設備，並獲取該設備的唯一標識，透過加密方法對計量資料、設備的唯一標識以及接收到所述信標資訊時對應的第三時間戳進行加密，獲得第三加密資訊，然後終端設備將第三加密資料與第一加密資料進行比較，在比較結果不符合記錄要求時，表明接收到的該計量設備的計量資料與產生第一加密資料時所依據的計量資料不相同，從而可以表明接收到的該計量設備的計量資料是不真實的，此時可以將不真實情況回饋至相關技術人員，以加強資料傳輸過程安全性。
在另一些實施例中，當所述終端設備接收到的資訊包括計量資料、第一加密資料以及識別標識中的設備編號時，所述終端設備可以在預先儲存的資訊中查找與所述設備編號對應的設備，並獲取該設備的唯一標識，透過加密方法對計量資料、設備的唯一標識以及接收到所述信標資訊時對應的第三時間戳進行加密，獲得第三加密資訊，然後將計量資料、識別標識、第一加密資料以及第三加密資料發送至伺服器，以便伺服器進行進一步的驗證，從而提高資料傳輸的安全性。
需要說明的是，一些實施例中，第三時間戳可以為終端設備接收到信標資訊時對應的時間。第三時間戳與產生第一加密資料時所用的第一時間戳可以在同一時間視窗或者預設的時間視窗期。例如，預先設置的時間視窗為60秒，產生第一加密資料時所用的時間為16時12分24秒，則第三時間戳可以在16時12分24秒到16時13分24秒之間。
需要說明的是，上述加密方法可以與計量設備採用的加密方法相同，也可以是與計量設備所採用的加密方法不同的方法，本說明書對此不作限定。
S30：所述伺服器基於所述識別標識、所述計量資料以及接收到所述信標資訊時對應的第二時間戳產生第二加密資料。
一些實施例中，所述第二時間戳與所述第一時間戳可以在同一時間視窗或預設的時間視窗內。
本說明書一個實施例中，所述伺服器可以預先儲存各個計量設備的識別標識。所述識別標識可以包括設備唯一標識、設備編號等。其中，設備編號與設備唯一標識可以預先相互關聯。第二時間戳可以包括伺服器接收到信標資訊時對應的時間。時間視窗可以表示一個預設時間段。所述第二時間戳與所述第一時間戳在同一時間視窗可以理解為：以第一時間戳為起始時間，起始時間與預設時間段之和為終止時間，第二時間戳可以在起始時間與終止時間之間。一些實施例中，所述第二時間戳與所述第一時間戳在同一時間視窗，可以防止資料被篡改。
本說明書一個實施例中，由於在資訊廣播和資料傳輸過程中，可能會存在計量資料被惡意虛構或篡改的情況，所以，伺服器在接收到信標信息之後，可以透過加密演算法對計量資料、識別標識中的設備唯一標識以及對應時間進行加密，獲得加密資料。
一些實施例中，由於所述伺服器接收到的識別標識中包括設備編號，所以為了保證資料的安全，可以獲得與設備編號對應的設備唯一標識。例如一些實施場景中，所述伺服器可以預先儲存各個計量設備的識別標識，且識別標識中包括的設備編號與設備唯一標識相互關聯，伺服器接收到的識別標識中包括設備編號時，可以根據所述信標資訊中包括的設備編號在伺服器中查找對應的設備唯一標識，然後透過加密演算法對計量資料、查找到的設備唯一標識以及對應時間進行加密，獲得第二加密資料。
另一些實施例中，為了保證資料的安全，伺服器在接收到所述信標資訊之後，可以先根據所述識別標識中的設備編號在伺服器中查找對應的設備唯一標識，然後將查找到的設備唯一標識與接收到的信標資訊中包括的設備唯一標識進行比較，若二者相同，再透過加密演算法對計量資料、識別標識中的設備唯一標識以及對應時間進行加密，獲得第二加密資料。一些實施例中，若查找到的設備唯一標識與接收到的信標資訊中包括的設備唯一標識不相同，則可以回饋至相關技術人員，以加強資料傳輸過程安全性。
需要說明的是，所述加密方法可以是計量設備採用的加密方法，也可以是與計量設備所採用的加密方法不同的方法，本說明書對此不作限定。
S32：所述伺服器比較所述第二加密資料與所述第一加密資料，在比較結果符合記錄要求時記錄所述計量資料。
一些實施例中，所述伺服器在產生第二加密資料後，會將其與之前接收到的加密資料進行比較，以確定所接收到的計量資料是否被篡改，從而提高資料傳輸的安全性。其中，符合記錄要求可以包括比較結果在預設誤差範圍內，或者比較結果相同，或者其它要求等。
本說明書一個實施例中，當伺服器接收到信標資訊並基於相關資訊產生第二加密資料後，可以將所述第二加密資料與接收到的信標資訊中包括的第一加密資料進行比較。若比較結果符合記錄要求，表明接收到的該計量設備的計量資料與產生第一加密資料時所依據的計量資料相同，從而可以表明接收到的該計量設備的計量資料是真實的，伺服器可以記錄該計量設備的計量資料。否則，表明接收到的計量設備的計量資料與產生第一加密資料時所依據的計量資料並不相同，從而可以表明接收到的該計量設備的計量資料可能在前期的資料傳輸過程中被惡意虛構或篡改了，是不真實的。
一些實施例中，當伺服器接收到計量資料、識別標識、第一加密資料以及第三加密資料時，可以將所述第二加密資料與接收到的第一加密資料、第三加密資料進行比較。當第二加密資料、第一加密資料、第三加密資料的比較結果符合記錄要求時，表明接收到的該計量設備的計量資料與產生第一加密資料時所依據的計量資料相同，從而可以表明接收到的該計量設備的計量資料是真實的，伺服器可以記錄該計量設備的計量資料。
需要說明的是，當出現接收到的該計量設備的計量資料可能在前期的資料傳輸過程中被惡意虛構或篡改的情況時，伺服器可以將該不真實的情況回饋至相關技術人員，以加強資料傳輸過程安全性。這樣，無需抄表人員肉眼觀測，便可以獲取各個計量設備的計量資料，還可以保證伺服器記錄的資料的真實性。
本說明書還提供另一種場景示例。例如，實際應用過程中，在一個社區的某棟樓裡有多戶業主，每戶業主家分別對應一個計量設備，在該棟樓可以設置一個智能總表。各個計量設備在讀取各自的計量資料並產生對應的第一加密資料之後可以透過藍牙的方式進行廣播，智能總表透過掃描並接收該計量設備廣播的資訊後可以進行匯總，然後透過與伺服器建立的通訊連接將匯總資訊發送至伺服器，伺服器透過對接收到的資訊進行驗證，從而可以獲得計量設備的真實資料。這樣，無需抄表人員肉眼觀測或上門觀測，便可以獲取各個計量設備的計量資料，保證伺服器記錄的資料的真實性。其中，計量設備以及智能總表可以包括藍牙模組和/或WiFi模組，計量設備與智能總表之間可以透過藍牙或者WiFi網路進行連接和資料傳輸，且計量設備處於從模式用來廣播資訊。此外，智能總表還可以包括遠端通訊模組，可以與遠端的伺服器進行通訊連接，實現與伺服器的資料傳輸。
本說明書實施例提供的一種資料讀取方法，計量設備可以將自身的計量資料加密後透過藍牙的方式進行廣播，伺服器在收到資訊後，基於對應的資訊進行加密，並將加密資料與接收到的加密資料進行比較。這樣，無需抄表人員肉眼觀測或上門觀測，便可以獲取各個計量設備的計量資料，從而可以保證伺服器記錄的資料的真實性的同時，可以有效解決資料傳輸過程中被惡意篡改的問題，提高資料讀取的安全性。

其中，計量設備可以包括藍牙模組、WiFi模組，且處於從模式用來廣播資訊。此外，計量設備還可以包括遠端通訊模組，可以與遠端的伺服器進行通訊連接，實現與伺服器的資料傳輸。
本說明書一個實施例中，各個計量設備在讀取各自的計量資料並產生對應的第一加密資料之後可以透過藍牙或者WiFi網路的方式進行廣播，伺服器掃描並接收該計量設備廣播的資訊後，可以透過對接收到的資訊進行驗證，從而獲得計量設備的真實資料。這樣，不僅無需抄表人員肉眼觀測或上門觀測，而且也無需終端設備進行對應的處理，便可以獲取各個計量設備的計量資料，保證伺服器記錄的資料的真實性，提高資料讀取的安全性。

對於計量設備一側，當使用者或工作人員觸發對應的指令時，計量設備可以基於該指令開始獲取對應的計量資料，並基於計量資料、識別標識以及時間戳產生第一加密資料，然後廣播對應資訊，以便伺服器基於接收到的資訊產生第二加密資料並進行比較，確定接收到的計量資料是否是所述計量設備獲得的真實資料，從而可以防止資料傳輸過程中被惡意篡改或虛構。
本說明書中上述方法的各個實施例均採用遞進的方式描述，各個實施例之間相同相似的部分互相參見即可，每個實施例重點說明的都是與其他實施例的不同之處。相關之處參見方法實施例的部分說明即可。

在20世紀90年代，對於一個技術的改進可以很明顯地區分是硬體上的改進(例如，對二極體、電晶體、開關等電路結構的改進)還是軟體上的改進(對於方法流程的改進)。然而，隨著技術的發展，當今的很多方法流程的改進已經可以視為硬體電路結構的直接改進。設計人員幾乎都透過將改進的方法流程程式設計到硬體電路中來得到對應的硬體電路結構。因此，不能說一個方法流程的改進就不能用硬體實體模組來實現。例如，可程式設計邏輯裝置(Programmable Logic Device, PLD)(例如現場可程式設計閘陣列(Field Programmable Gate Array，FPGA))就是這樣一種積體電路，其邏輯功能由使用者對裝置程式設計來確定。由設計人員自行程式設計來把一個數位系統“整合”在一片PLD上，而不需要請晶片製造廠商來設計和製作專用的積體電路晶片。而且，如今，取代手工地製作積體電路晶片，這種程式設計也多半改用“邏輯編譯器(logic compiler)”軟體來實現，它與程式開發撰寫時所用的軟體編譯器相類似，而要編譯之前的原始碼也得用特定的程式設計語言來撰寫，此稱之為硬體描述語言(Hardware Description Language，HDL)，而HDL也並非僅有一種，而是有許多種，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL (Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)與Verilog。本領域技術人員也應該清楚，只需要將方法流程用上述幾種硬體描述語言稍作邏輯程式設計並程式設計到積體電路中，就可以很容易得到實現該邏輯方法流程的硬體電路。
控制器可以按任何適當的方式實現，例如，控制器可以採取例如微處理器或處理器以及儲存可由該(微)處理器執行的電腦可讀程式碼(例如軟體或韌體)的電腦可讀媒體、邏輯閘、開關、特殊應用積體電路(Application Specific Integrated Circuit，ASIC)、可程式設計邏輯控制器和嵌入微控制器的形式，控制器的例子包括但不限於以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20 以及Silicone Labs C8051F320，記憶體控制器還可以被實現為記憶體的控制邏輯的一部分。本領域技術人員也知道，除了以純電腦可讀程式碼方式實現控制器以外，完全可以透過將方法步驟進行邏輯程式設計來使得控制器以邏輯閘、開關、特殊應用積體電路、可程式設計邏輯控制器和嵌入微控制器等的形式來實現相同功能。因此這種控制器可以被認為是一種硬體部件，而對其內包括的用於實現各種功能的裝置也可以視為硬體部件內的結構。或者甚至，可以將用於實現各種功能的裝置視為既可以是實現方法的軟體模組又可以是硬體部件內的結構。
上述實施例闡明的系統、裝置、模組或單元，具體可以由電腦晶片或實體實現，或者由具有某種功能的產品來實現。一種典型的實現設備為電腦。具體地，電腦例如可以為個人電腦、膝上型電腦、車載人機交互設備、蜂巢式電話、相機電話、智慧型電話、個人數位助理、媒體播放機、導航設備、電子郵件設備、遊戲控制台、平板電腦、穿戴式設備或者這些設備中的任何設備的組合。
雖然本說明書實施例提供了如實施例或流程圖所述的方法操作步驟，但基於習知或者無創造性的手段可以包括更多或者更少的操作步驟。實施例中列舉的步驟順序僅僅為眾多步驟執行順序中的一種方式，不代表唯一的執行順序。在實際中的裝置或終端產品執行時，可以按照實施例或者圖式所示的方法循序執行或者並存執行(例如並行處理器或者多執行緒處理的環境，甚至為分散式資料處理環境)。術語“包括”、“包含”或者其任何其他變體意在涵蓋非排他性的包含，從而使得包括一系列要素的過程、方法、產品或者設備不僅包括那些要素，而且還包括沒有明確列出的其他要素，或者是還包括為這種過程、方法、產品或者設備所固有的要素。在沒有更多限制的情況下，並不排除在包括所述要素的過程、方法、產品或者設備中還存在另外的相同或等同要素。
為了描述的方便，描述以上裝置時以功能分為各種模組分別描述。當然，在實施本說明書實施例時可以把各模組的功能在同一個或多個軟體和/或硬體中實現，也可以將實現同一功能的模組由多個子模組或子單元的組合實現等。以上所描述的裝置實施例僅僅是示意性的，例如，所述單元的劃分，僅僅為一種邏輯功能劃分，實際實現時可以有另外的劃分方式，例如多個單元或元件可以結合或者可以整合到另一個系統，或一些特徵可以忽略，或不執行。另一點，所顯示或討論的相互之間的耦合或直接耦合或通訊連接可以是透過一些介面，裝置或單元的間接耦合或通訊連接，可以是電性，機械或其它的形式。
本領域技術人員也知道，除了以純電腦可讀程式碼方式實現控制器以外，完全可以透過將方法步驟進行邏輯程式設計來使得控制器以邏輯閘、開關、專用積體電路、可程式設計邏輯控制器和嵌入微控制器等的形式來實現相同功能。因此這種控制器可以被認為是一種硬體部件，而對其內部包括的用於實現各種功能的裝置也可以視為硬體部件內的結構。或者甚至，可以將用於實現各種功能的裝置視為既可以是實現方法的軟體模組又可以是硬體部件內的結構。

It should be noted that the following embodiment descriptions of metering device/terminal device/server interaction do not limit the technical solutions in other applicable scenarios based on this specification. A specific embodiment is shown in FIG. 2. In an embodiment of a data reading method provided in this specification, the method may include: S10: Acquire the measurement data on the measurement device, based on the measurement data, the identification and the The first time stamp generates the first encrypted data, and the first time stamp includes the time corresponding to when the metering device acquires the metering data.

In the 1990s, an improvement in a technology could be clearly distinguished as a hardware improvement (for example, improvements to circuit structures such as diodes, transistors, switches, etc.) or software improvements (for methods and procedures) Improve).

For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is an integrated circuit whose logic function is determined by user programming of the device . A digital system is "integrated" on a PLD by the designer's own programming, without the need for a chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, instead of hand-making integrated circuit chips, this kind of programming is now mostly implemented using "logic compiler" software, which is similar to the software compiler used in programming, but requires The source code before compilation must also be written in a specific programming language, which is called Hardware Description Language (HDL). Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., The most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that a hardware circuit for implementing the logic method flow can be easily obtained by simply programming the method flow in the above-mentioned several hardware description languages and programming it into an integrated circuit. The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable code (eg software or firmware) storing computer readable program code (eg software or firmware) executable by the (micro)processor Forms of media, logic gates, switches, Application Specific Integrated Circuits (ASICs), programmable logic controllers and embedded microcontrollers, examples of controllers include but are not limited to the following microcontrollers: ARC 625D , Atmel AT91SAM, Microchip PIC18F26K20 and Silicon Labs C8051F320, the memory controller can also be implemented as part of the memory control logic. Those skilled in the art also know that, in addition to implementing the controller in the form of pure computer readable code, it is possible to make the controller use logic gates, switches, special application integrated circuits, programmable logic through logic programming of method steps. The same function can be realized in the form of a controller and an embedded microcontroller, etc. Therefore, the controller can be regarded as a hardware component, and the devices for realizing various functions included in the controller can also be regarded as a structure in the hardware component. Or even, the means for implementing various functions can be regarded as both a software module for implementing the method and a structure within a hardware component. The systems, devices, modules or units described in the above embodiments may be specifically implemented by computer chips or entities, or by products with certain functions. A typical implementation device is a computer. Specifically, the computer can be, for example, a personal computer, a laptop computer, a vehicle-mounted human-computer interaction device, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console , tablet, wearable, or any combination of these devices.

Without further limitation, it does not preclude the presence of additional identical or equivalent elements in a process, method, product or apparatus comprising the stated elements. For the convenience of description, when describing the above device, the functions are divided into various modules and described respectively. Of course, when implementing the embodiments of this specification, the functions of each module may be implemented in the same one or more software and/or hardware, or the modules that implement the same function may be composed of multiple sub-modules or combinations of sub-units. realization etc. The apparatus embodiments described above are only illustrative. For example, the division of the units is only a logical function division. In actual implementation, there may be other division methods. For example, multiple units or elements may be combined or integrated into Another system, or some features can be ignored, or not implemented. On the other hand, the shown or discussed mutual coupling or direct coupling or communication connection may be through some interfaces, indirect coupling or communication connection of devices or units, and may be electrical, mechanical or other forms. Those skilled in the art also know that, in addition to implementing the controller in the form of pure computer readable code, the controller can be controlled by logic gates, switches, dedicated integrated circuits, programmable logic control by logically programming the method steps. The same function can be realized in the form of a device and an embedded microcontroller. Therefore, the controller can be regarded as a hardware component, and the devices included therein for realizing various functions can also be regarded as a structure in the hardware component. Or even, the means for implementing various functions can be regarded as both a software module for implementing the method and a structure within a hardware component.
