為使本發明實施例的目的、技術方案和優點更加清楚，下面將結合本發明實施例中的圖式，對本發明實施例中的技術方案進行清楚、完整地描述，顯然，所描述的實施例是本發明一部分實施例，而不是全部的實施例。基於本發明中的實施例，本領域普通技術人員在沒有作出創造性勞動前提下所獲得的所有其他實施例，都屬於本發明保護的範圍。
在本發明實施例中使用的術語是僅僅出於描述特定實施例的目的，而非旨在限制本發明。在本發明實施例和所附申請專利範圍中所使用的單數形式的“一種”、“所述”和“該”也旨在包括多數形式，除非上下文清楚地表示其他含義，“多種”一般包含至少兩種，但是不排除包含至少一種的情況。
應當理解，本文中使用的術語“和/或”僅僅是一種描述關聯對象的關聯關係，表示可以存在三種關係，例如，A和/或B，可以表示：單獨存在A，同時存在A和B，單獨存在B這三種情況。另外，本文中字符“/”，一般表示前後關聯對象是一種“或”的關係。
取決於語境，如在此所使用的詞語“如果”、“若”可以被解釋成為“在……時”或“當……時”或“回應於確定”或“回應於識別”。類似地，取決於語境，短語“如果確定”或“如果識別(陳述的條件或事件)”可以被解釋成為“當確定時”或“回應於確定”或“當識別(陳述的條件或事件)時”或“回應於識別(陳述的條件或事件)”。
還需要說明的是，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商品或者系統不僅包括那些要素，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商品或者系統所固有的要素。在沒有更多限制的情況下，由語句“包括一個……”限定的要素，並不排除在包括所述要素的商品或者系統中還存在另外的相同要素。
本案實施例可以應用於物聯網設備中，透過對物聯網設備中系統資源的佔用情況進行分析，以提供能夠正常升級的條件，使得升級能夠及時完成，並及時恢復主應用程式的運行，從而避免出現下載升級導致的運行系統不穩定問題。
現有技術中，物聯網設備的硬體資源、記憶體資源可能是一定的，且不夠大。在物聯網設備至少一個應用程式運行的過程中，可以針對物聯網設備中的程式進行升級，例如，應用程式的普通升級、版本的升級或者韌體升級等等。在升級過程中，為了確保物聯網設備與升級父親端之間的網路連接的安全性以及可靠性，通常需要物聯網設備與升級伺服端透過安全的HTTPS(Hypertext transfer protocol Secure，超文件傳輸安全協定)下載待升級程式，也即是安裝包。但是，由於HTTPS的下載升級過程中，需要增加證書交換以及交換處理(hand shaking)驗證的過程，對系統記憶體資源的消耗更大。因此，資源受限的物聯網設備往往無法使用HTTPS進行下載升級。並且，在一些資源受限的物聯網設備中如果同時進行應用程式的運行以及升級任務的下載時，由於資源受限，還容易出現物聯網設備的操作系統不穩定的技術問題。為了解決上述技術問題，發明人提出了本案的技術方案。
本案實施例中，針對資源受限的物聯網設備，可以在至少一個應用程式運行的過程中，檢測設備管理伺服端發送的升級觸發訊息，回應於該升級觸發訊息，可以基於至少一個應用程式的資源佔用，關閉至少部分應用程式，以使得物聯網設備系統中的資源能夠執行升級任務。從升級伺服端下載待升級程式之後，可以運行該待升級程式，完成物聯網設備的升級任務，之後，可以重新運行至少一個應用程式。此時，物聯網設備完成升級任務，且在升級結束之後重新運行至少一個應用程式，以使物聯網設備的系統恢復到穩定狀態，從而可以解決升級任務與主應用程式同時運行時導致的系統不穩定的技術問題。
下面將結合圖式對本案實施例進行詳細描述。
如圖1所示，為本案實施例提供的一種物聯網設備的程式升級方法的一個實施例的流程圖，所述方法可以包括以下幾個步驟：
101：在至少一個應用程式的運行過程中，檢測設備管理伺服端發送的升級觸發訊息。
本案實施例可以應用於物聯網設備中，所述物聯網設備可以指資源受限的電子設備，具體可以指記憶體資源小於設定的記憶體臨限值的電子設備。
物聯網設備在正常運行時，需要多個程式的支援，例如可以包括：引導程式(Bootloader)、OS(operating system、操作系統)、定時程式以及網路連接程式等，對於某些特定功能的物聯網設備，例如，影像感測器、聲音感測器等，還可以包括具有針對使用者提供某些特定功能的應用程式，例如，展示影像的應用程式、為使用者輸出聲音的應用程式等。
設備管理伺服端可以用於提供計算服務的設備，例如可以是個人電腦、超級電腦、筆記型電腦等設備構成，還可以是雲端伺服器構成，本案實施例對所述設備管理伺服端的具體類型不作出過多限定。
設備管理伺服端是指用於對物聯網設備進行管理的伺服端，通常可以對物聯網設備的服務請求進行回應，並進行處理，還可以對物聯網設備中的應用程式進行管理控制。在一些實施例中，當物聯網設備中的使用者應用程式進行版本更新或者升級時，設備管理伺服端可以由第三方伺服器構成，該第三方伺服器具體可以指開發該使用者應用程式的開發者為這個使用者應用程式設定的存取伺服器。
設備管理伺服端判斷物聯網設備存在升級需求時，可以發送升級觸發訊息至物聯網設備。所述升級觸發訊息中可以包括待升級程式的程式名稱以及下載位址等資訊，透過升級觸發訊息可以確定下載位址，從而從升級伺服端下載待升級程式。
所述至少一個應用程式可以指所述物聯網設備中的主應用(MAIN APP Task)模組，主應用模組是指針對使用者制定的具有特定應用目的的軟體模組，透過主應用模組主要為使用者可以在物聯網設備上使用的程式，不包括物聯網設備的操作系統、網路模組等。
102：回應於所述升級觸發訊息，基於所述至少一個應用程式的資源佔用，關閉至少部分應用程式。
物聯網設備中的至少一個應用程式在運行過程中會消耗該物聯網設備的資源，其中，可以包括硬體資源或記憶體資源。由於物聯網設備的資源較小，如果至少一個應用程式的資源佔用較大，導致物聯網設備的剩餘資源較少，不能夠及時進行升級，或者升級程式與至少一個應用程式的運行存在資源爭奪現象。例如，假設物聯網設備的記憶體資源為100K，而至少一個應用程式佔用的資源為60K，剩餘資源為40K，但是若升級任務需要60K的記憶體資源，由於剩餘資源不夠，不能完成升級，若升級任務需要38K的記憶體資源，在至少一個應用程式以及升級任務同時進行升級時需要使用98K的記憶體資源，可以進行任務升級，但是由於記憶體資源消耗過多，容易出現資源使用衝突，資源爭搶等現象，導致物聯網設備出現不穩定現象。
在回應升級觸發訊息之後，可以開始啓動升級。此時可以基於至少一個應用程式的資源佔用，關閉至少部分應用程式，透過至少部分應用程式的關閉，可以使得物聯網設備中的部分資源被解除佔用，提高了可應用資源的供應量，物聯網設備即可以在關閉了至少部分應用程式的基礎上進行升級。
103：從升級伺服端下載待升級程式。
可選地，所述回應升級觸發訊息中可以包括待升級程式的下載位址，可以基於待升級程式的下載位址，從伺服端下載待升級程式。
可選地，所述回應升級觸發訊息中可以包括待升級程式的下載提示資訊，物聯網設備可以根據回應升級觸發訊息中的下載提示資訊，確定待升級程式的下載位址，從而基於下載位址，從升級伺服端下載待升級程式。
在一些實施例中，所述從升級伺服端下載待升級程式具體可以是：基於下載位址，向所述下載位址對應的升級伺服端發送下載請求，基於所述下載請求建立與所述升級伺服端的交換處理連接，連接完成，根據已建立的交換處理連接，與所述升級伺服端交換證書之後，可以從升級伺服端下載待升級程式。
104：運行所述待升級程式，完成所述物聯網設備的升級任務。
物聯網設備在下載待升級程式之後，可以啓動該待升級程式，以完成所述物聯網設備的升級任務。
105：重新運行所述至少一個應用程式。
所述重新運行所述至少一個應用程式可以包括重新啓動被關閉的至少部分應用程式，以重新運行至少一個應用程式。
本案實施例中，透過針對資源受限的物聯網設備，可以在至少一個應用程式運行的過程中，檢測設備管理伺服端發送的升級觸發訊息，回應於該升級觸發訊息，可以基於至少一個應用程式的資源佔用，關閉至少部分應用程式，以使得物聯網設備系統中的資源能夠執行升級任務。從升級伺服端下載待升級程式之後，可以運行該待升級程式，完成物聯網設備的升級任務，之後，可以重新運行至少一個應用程式。此時，物聯網設備完成升級任務，且在升級結束之後重新運行至少一個應用程式，以使物聯網設備的系統恢復到穩定狀態，從而可以解決升級任務與主應用程式同時運行時導致的系統不穩定的技術問題。
為了解決下載任務與至少一個應用程式同時運行產生的資源衝突問題，可以關閉所有應用程式，增加系統中的可利用資源，從而確保程式升級能夠正常完成。作為一個實施例，所述回應於所述升級觸發訊息，基於所述至少一個應用程式的資源佔用，關閉至少部分應用程式可以包括：
回應於所述升級觸發訊息，基於所述至少一個應用程式的資源佔用，關閉所有應用程式。
為了確保下載的安全性，所述從升級伺服端下載待升級程式可以包括：
基於超文件傳輸安全協定，從升級伺服端下載待升級程式。
所述超文件傳輸安全協定由於需要資源較多，在未關閉至少部分應用程式時，不可以使用或者受資源限制影響而使用效果不佳，本案中透過關閉至少部分應用程式可以使得超文件傳輸安全協定得以使用，以提高下載的安全性，從而提高升級任務的安全性。
如圖2所示，為本案實施例提供的一種物聯網設備的程式升級方法的又一個實施例的流程圖，所述方法可以包括以下幾個步驟：
201：在至少一個應用程式的運行過程中，檢測設備管理伺服端發送的升級觸發訊息。
本案實施例中的部分步驟的處理過程與圖1所示的實施例中的部分內容相同，在此不再贅述。
202：回應於所述升級觸發訊息，基於所述至少一個應用程式的資源佔用，關閉所有應用程式。
203：切換所述物聯網設備至下載模式，以從升級伺服端下載待升級程式。
作為一種可能的實現方式，可以透過執行模式指令，以切換物聯網設備至下載模式，從升級伺服端下載待升級程式。
切換物聯網設備至下載模式時，需要物聯網設備不處於升級模式。因此，所述切換所述物聯網設備至下載模式時，還可以包括：設定升級標誌位為第一標誌，重啓所述物聯網設備，檢測所述升級標誌位為第一標誌時，確定物聯網設備切換至下載模式，以從升級伺服端下載待升級程式。
204：檢測所述待升級程式下載完成時，切換所述物聯網設備至升級模式。
檢測所述待升級程式完成具體可以是檢測所述待升級程式接收到所述升級伺服端發送的結束指令，即可以確定所述待升級程式下載完成。
切換所述物聯網設備至升級模式具體可以包括：檢測所述待升級程式下載完成時，設定升級標誌位為第二標誌，重啓物聯網設備，並檢測所述升級標誌位為第二標誌時，確定物聯網設備切換至升級模式。
在檢測所述待升級程式下載完成時，切換所述物聯網設備至升級模式具體可以包括在檢測所述待升級程式下載完成時，清除所述下載模式，並切換所述物聯網設備至升級模式。
205：檢測所述物聯網設備處於升級模式時，運行所述待升級程式，完成所述物聯網設備的升級任務。
所述物聯網處理升級模式時，也即檢測到升級標誌位為第二標誌時，可以運行待升級程式，完成所述物聯網設備的升級任務。
升級標誌位可以指用於標識升級模式的變量，透過升級標誌位的設定可以判斷當前是否可以對物聯網設備的程式進行升級。例如，所述升級標誌位可以透過表示為整型變量flag(標誌)，為flag設定的第一標誌具體可以指flag等於0；為flag設定的第二標誌具體可以指flag等於1。在升級標誌位為第一標誌時，未處於升級狀態，不執行物聯網設備的待升級程式。在升級標誌位為第二標誌時，執行對物聯網設備的升級程式，完成對物聯網設備的升級。
206：重新運行所述至少一個應用程式。
本案實施例中，透過設定下載模式，以使得物聯網設備可以明確當前運行環境，從而根據當前運行環境，下載待升級程式，下載成功之後可以切換所述物聯網設備至升級模式，檢測所述物聯網設備處於升級模式時，可以運行待升級程式，完成所述物聯網設備的升級任務。在這一過程中，透過模式的作用可以明確執行的內容，以提高升級效率。

設定所述物聯網設備為下載模式並重啓所述物聯網設備，以切換所述物聯網設備至下載模式。
檢測升級標誌位為第一標誌時，從升級伺服端下載待升級程式。
物聯網設備中下載模式的開啓之後，可以透過重啓的方式，使物聯網設備由正常運行模式切換至下載模式，重啓之後，處於下載模式的物聯網設備即可以開始下載待升級程式。在下載模式下，升級標誌位為第一標誌時，可以從升級伺服端下載待升級程式。由於採用重啓的方式，物聯網設備中的應用程式關閉，將應用程式與下載過程進行了隔離，以確保下載效率。
由於物聯網設備的至少一個應用程式中按照啓動順序的先後順序排列，具體可以包括：啓動程式、操作系統、網路模組、使用者應用程式等。不同的應用程式具備不同的功能。而啓動程式是為了將至少一個應用程式與升級任務完全隔離以執行，可以啓動階段將升級任務與至少一個應用程式在物聯網設備進行隔離。
作為一種可能的實現方式，所述檢測升級標誌位為第一標誌時，從升級伺服端下載待升級程式可以包括：
在所述物聯網設備的引導程式啓動時，檢測所述升級標誌位為第一標誌時，從升級伺服端下載待升級程式。
本案實施例中，在物聯網設備啓動引導程式之後，即可以開始進行待升級程式的下載，以使得物聯網設備能夠在引導程式啓動其他程式不啓動的情況下即可以開始進行待升級程式的下載，以實現升級任務與使用者應用、操作系統等程式的隔離，在升級結束之後，再啓動物聯網設備的至少一個應用程式即可，從而確保應用程式的正常運行，以避免出現因下載任務以及使用者應用同時執行產生資源爭奪而導致系統運行不穩定、升級任務不穩定的問題。

本案實施例中的部分步驟的處理過程與圖1~圖2中所示的實施例中的部分內容相同，在此不再贅述。
本案實施例中，物聯網設備的升級整體分為了三個階段，第一階段，在物聯網設備至少一個應用程式正常運行的過程中，可以檢測到設備管理伺服端發送的升級觸發訊息，此時物聯網設備可以回應於該升級觸發訊息，基於至少一個應用程式的資源佔用，關閉所有應用程式，進而可以將物聯網設備設定為下載模式，並重新啓動，此時，即可以切換物聯網設備至下載模式，進行待升級程式的下載。在物聯網設備重啓之後，引導程式先啓動，啓動結束時，物聯網設備即可以開始進入啓動階段，透過對升級標誌位的檢測可以在確定升級標誌位為第一標誌時，啓動物聯網設備的操作系統單元，並在操作系統啓動完畢時，建立物聯網設備與升級伺服端的連接，從而完成下載環境的搭建。在下載過程中，可以啓動監控任務，在從升級伺服端下載待升級程式時，利用監控任務監控待升級程式的下載過程，從而可以在檢測待升級程式下載完成時，清除下載模式，並設定升級標誌位為第二標誌。此時待升級程式經過模式切換、重啓設備、搭載下載環境之後完成待升級程式的下載工作。第二階段，在將升級標誌位設定為第二標誌之後，即完成待升級程式的下載工作，可以開始執行待升級程式的安裝工作，此時，可以重啓物聯網設備，並在所述物聯網設備的引導程式啓動之後，檢測升級標誌位。當檢測到升級標誌位為第二標誌時，說明此時物聯網設備已切換至升級模式，在升級模式下，即可以開始運行待升級程式，完成物聯網設備的升級任務，此時即完成待升級程式的安裝工作。第三階段，物聯網設備在安裝待升級程式之後，可以設定升級標誌位為第一標誌，將其切換為正常的工作模式，此時，重啓所述物聯網設備，即可以重新運行至少一個應用程式，完成整個物聯網設備的升級。在這一升級過程中，由於物聯網設備的下載過程以及安裝過程均未有應用程式參與運行，可以使得物聯網設備能夠單獨處理待升級程式的下載以及安裝，之後再正常運行至少一個應用程式，避免出現應用程式的運行與下載以及安裝過程出現資源衝突，提高了系統的穩定性。
為了便於理解，以所述物聯網設備為智慧音箱為例對本案實施例進行詳細說明。圖4中的智慧音箱M1可以與設備管理伺服端M2建立通信連接，還可以與升級伺服端M3建立通信連接。所述智慧音箱M1可以在正常工作過程中可以正常運行至少一個應用程式。設備管理伺服端M2可以發送401升級觸發訊息至智慧音箱M1。在至少一個應用程式的運行過程中，智慧音箱M1可以檢測402設備管理伺服端M2發送的升級觸發訊息。
智慧音箱M1可以回應於該升級觸發訊息，基於所述至少一個應用程式的資源佔用，關閉所有應用程式403。之後，智慧音箱可以設定所述物聯網設備為下載模式404，之後可以運行405重啓指令(Reboot)。重啓指令運行之後，引導程式(Bootloader)即開始啓動406。智慧音箱判斷407升級標誌位(Upgrade Flag)是第一標誌時，啓動408操作系統單元，建立409網路連接。網路連接成功(Network Ready)之後，檢測410處於下載模式時，啓動411監控任務(Monitor Task)，從所述升級伺服端M3下載412待升級程式並利用所述監控任務監控所述待升級程式的下載過程。檢測所述待升級程式下載完成時，清除所述下載模式並設定升級標誌位為第二標誌413。
之後，智慧音箱M1可以運行重啓指令405，在執行引導程式啓動406後，檢測407所述升級標誌位為第二標誌時，確認切換至升級模式，從而在升級模式下，運行414所述待升級程式，完成所述物聯網設備的升級任務。升級成功之後，可以清除升級標誌位，也即將升級標誌位設定為第一標誌415。
之後，智慧音箱M1可以重啓所述物聯網設備405，執行406啓動引導程式；執行407檢測所述升級標誌位為第一標誌時，以及執行步驟408啓動操作系統並409建立網路連接；410檢測未處於下載模式時，啓動所述至少一個應用程式417。

502：回應於所述升級觸發訊息，如果所述至少一個應用程式的資源佔用大於相對應的佔用臨限值，關閉至少部分應用程式。

利用所述目標資源以及所述物聯網設備的總資源，確定所述佔用臨限值。
可選地，所述利用所述目標資源以及所述物聯網設備的總資源，確定所述佔用臨限值可以包括：計算所述目標資源與所述物聯網設備的總資源的比值，獲得升級任務的佔用比例，計算整數1與升級任務的佔用比例的差，獲得所述佔用臨限值。所述回應於所述升級觸發訊息，如果所述至少一個應用程式的資源佔用大於相對應佔用臨限值，關閉至少部分應用程式包括：回應於所述升級觸發訊息，如果所述至少一個應用程式的資源佔用與物聯網設備的總資源的比例大於相對應的佔用臨限值，關閉至少部分應用程式。
在某些實施例中，所述回應於所述升級觸發訊息，如果所述至少一個應用程式的資源佔用大於相對應的佔用臨限值，關閉至少部分應用程式可以包括：回應於所述升級觸發訊息，如果所述至少一個應用程式的資源佔用大於相對應的佔用臨限值，基於所述佔用臨限值，重新確定所述至少一個應用程式的可佔用資源；關閉至少部分應用程式，以使得至少一個應用程式中的剩餘應用程式佔用的資源小於所述可佔用資源。
503：從升級伺服端下載待升級程式。
504：運行所述待升級程式，完成所述物聯網設備的升級任務。

本案實施例中，在至少一個應用程式運行過程中，可以檢測設備管理伺服端發送的升級觸發訊息。之後，可以回應於所述升級觸發訊息，如果所述至少一個應用程式的資源佔用大於佔用臨限值，可以關閉至少部分應用程式。透過關閉至少部分應用程式可以將物聯網設備中的部分被佔用的資源解除佔用，從而可以使物聯網設備的資源可以完成待升級程式且不影響剩餘部分的應用程式的穩定運行。
如圖6所示，為本案實施例提供的一種物聯網設備的程式升級方法的又一個實施例的流程圖，所述方法可以包括以下幾個步驟：
601：在至少一個應用程式的運行過程中，檢測設備管理伺服端發送的升級觸發訊息。
602：確定與所述升級觸發訊息對應升級任務的升級類型。
其中，所述升級類型包括全量升級或增量升級。

在某些實施例中，可以對至少一個應用程式分別設定各自的運行級別，在關閉至少部分應用程式時，可以按照每個應用程式的運行級別，按照從低到高的順序關閉對應的應用程式，直至物聯網設備的剩餘資源滿足升級任務的資源需求。例如，第一應用程式的運行級別為一級，第二應用程式的運行級別為二級，一級應用程式的運行級別大於二級應用程式，可以按照二級應用程式運行級別低於一級應用程式運行級別的關閉規則，先關閉第二應用程式，如果物聯網設備中的剩餘資源滿足升級任務的資源需求不再關閉第一應用程式，即可以開始執行下載任務；如果物聯網設備中的剩餘資源不滿足升級任務的資源需求，需要關閉第一應用程式，直至物聯網設備中的剩餘資源滿足升級任務的資源需求。

可選地，所述利用所述目標資源以及所述物聯網設備的總資源，確定所述佔用臨限值可以包括：計算所述目標資源與所述物聯網設備的總資源的比值，獲得升級任務的佔用比例，計算整數1與升級任務的佔用比例的差，獲得所述佔用臨限值。

It should be understood that the term "and/or" used herein is only an association relationship describing associated objects, indicating that there can be three relationships, for example, A and/or B can mean: A alone exists, and A and B exist at the same time. There are three cases of B alone. In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.
Depending on the context, the words "if" and "if" as used herein can be interpreted as "when" or "when" or "in response to certainty" or "in response to recognition". Similarly, depending on the context, the phrase "if determined" or "if recognized (statement or event)" can be interpreted as "when determined" or "in response to determination" or "when recognized (statement or event)" Event)" or "response to identification (statement or event)".
It should also be noted that the terms "include", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a commodity or system that includes a series of elements not only includes those elements, but also includes those elements that are not explicitly listed. Other elements of, or also include elements inherent to this kind of commodity or system. If there are no more restrictions, the element defined by the sentence "including a..." does not exclude the existence of other identical elements in the commodity or system that includes the element.
The embodiments of this case can be applied to IoT devices. By analyzing the occupancy of system resources in the IoT devices, the conditions for normal upgrades can be provided, so that the upgrade can be completed in time, and the operation of the main application can be restored in time, thereby avoiding The running system is unstable due to download and upgrade.
In the prior art, the hardware resources and memory resources of the Internet of Things device may be fixed and not large enough. During the running of at least one application of the IoT device, the program in the IoT device can be upgraded, for example, a general upgrade of an application, a version upgrade or a firmware upgrade, etc. During the upgrade process, in order to ensure the security and reliability of the network connection between the IoT device and the upgraded father, it is usually necessary for the IoT device and the upgrade server to pass the secure HTTPS (Hypertext transfer protocol Secure). Protocol) Download the program to be upgraded, that is, the installation package. However, since the HTTPS download and upgrade process needs to increase the process of certificate exchange and hand shaking (hand shaking) verification, the consumption of system memory resources is greater. Therefore, resource-constrained IoT devices are often unable to download and upgrade using HTTPS. Moreover, in some resource-constrained IoT devices, if the application program is run and the upgrade task is downloaded at the same time, due to the limited resources, the technical problem of the instability of the operating system of the IoT device is prone to occur. In order to solve the above technical problems, the inventor proposed the technical solution of this case.
In the embodiment of this case, for the resource-constrained IoT device, the upgrade trigger message sent by the device management server can be detected during the running of at least one application, and the response to the upgrade trigger message can be based on the at least one application. Resource occupation, close at least part of the application, so that the resources in the IoT device system can perform the upgrade task. After downloading the program to be upgraded from the upgrade server, the program to be upgraded can be run to complete the upgrade task of the IoT device, and then at least one application can be re-run. At this point, the IoT device completes the upgrade task, and reruns at least one application after the upgrade is completed to restore the system of the IoT device to a stable state, which can solve the system failure caused by the upgrade task and the main application running at the same time. Stable technical issues.
The embodiments of this case will be described in detail below in conjunction with the drawings.
As shown in FIG. 1, a flowchart of an embodiment of a program upgrade method for an Internet of Things device provided in this embodiment of the present application, the method may include the following steps:
101: During the running of at least one application, detect the upgrade trigger message sent by the device management server.
The embodiments of this case can be applied to Internet of Things devices. The Internet of Things devices can refer to electronic devices with limited resources, and specifically can refer to electronic devices with memory resources less than a set memory threshold.
When the Internet of Things devices are running normally, they need the support of multiple programs, such as bootloader, OS (operating system, operating system), timing program, and network connection program, etc., for some specific functions of the object Networked devices, for example, image sensors, sound sensors, etc., may also include applications that provide certain functions for users, for example, applications that display images, applications that output sounds to users, and so on.
The device management server can be used to provide computing services. For example, it can be composed of devices such as personal computers, supercomputers, and notebook computers, or it can be composed of cloud servers. Make too many restrictions.
The device management server refers to the server used to manage the Internet of Things devices. It can usually respond to and process service requests from the Internet of Things devices, and can also manage and control the applications in the Internet of Things devices. In some embodiments, when the user application in the Internet of Things device is version updated or upgraded, the device management server may be constituted by a third-party server, and the third-party server may specifically refer to the developer of the user application. The access server set by the developer for this user application.
When the device management server determines that there is an upgrade requirement for the IoT device, it can send an upgrade trigger message to the IoT device. The upgrade trigger message may include information such as the program name and download address of the program to be upgraded, and the download address can be determined through the upgrade trigger message, so that the program to be upgraded can be downloaded from the upgrade server.

At least one application in the Internet of Things device consumes resources of the Internet of Things device during the running process, which may include hardware resources or memory resources. Due to the small resources of the IoT device, if at least one application has a large resource occupancy, the remaining resources of the IoT device are small, and the upgrade cannot be performed in time, or there is a resource contention between the upgrade program and the operation of at least one application. . For example, suppose that the memory resource of the IoT device is 100K, and the resource occupied by at least one application is 60K, and the remaining resource is 40K. However, if the upgrade task requires 60K memory resources, the upgrade cannot be completed because the remaining resources are insufficient. The upgrade task requires 38K of memory resources. When at least one application and the upgrade task are upgraded at the same time, 98K of memory resources are required. Task upgrades can be performed. However, due to excessive memory resource consumption, resource conflicts and resource contention are prone to occur. Phenomena such as grabbing have led to instability of IoT devices.
After responding to the upgrade trigger message, you can start the upgrade. At this time, based on the resource occupation of at least one application, at least part of the application can be closed. By closing at least part of the application, part of the resources in the IoT device can be unoccupied, and the supply of applicable resources can be increased.

As an embodiment, in response to the upgrade trigger message, shutting down at least part of the application based on the resource occupation of the at least one application may include:
In response to the upgrade trigger message, all applications are closed based on the resource occupation of the at least one application.
In order to ensure the security of the download, the downloading of the program to be upgraded from the upgrade server may include:
Based on the hyper-file transfer security protocol, download the program to be upgraded from the upgrade server.
The hyper-file transfer security protocol requires more resources, and cannot be used when at least part of the application is not closed or is affected by resource restrictions and has poor use effect. In this case, closing at least part of the application can make hyper-file transfer secure The agreement can be used to improve the security of the download, thereby improving the security of the upgrade task.
