下面將參照附圖更詳細地描述本揭露的優選實施方式。雖然附圖中顯示了本揭露的優選實施方式，然而應該理解，可以以各種形式實現本揭露而不應被這裡闡述的實施方式所限制。相反，提供這些實施方式是為了使本揭露更加透徹和完整，並且能夠將本揭露的範圍完整地傳達給本領域的技術人員。
圖1示出了物聯網設備與伺服器間的通信流程圖。
本揭露述及的物聯網設備100可以是但不限於PDA (Personal Digital Assistant，個人數位助理)智慧終端機、車輛(如無人汽車)、感測器、智慧家居設備(如可以包括但不限於智慧音箱、掃地機器人、智慧燈泡、智慧開關、智慧門鎖)等。其中PDA智慧終端機可以是但不限於快件跟蹤掃描記錄儀，用於實現零售開單、列印小票、盤點、資料上傳和日結等一種或多種功能的移動POS機。
物聯網(Internet of Things，簡稱IoT)，即“萬物相連的網際網路”是網際網路基礎上的延伸和擴充的網路，將各種資訊感測設備與網際網路結合起來而形成的一個巨大網路，實現在任何時間、任何地點，人、機、物的互聯互通。物聯網設備100可以通過物聯網與伺服器通信，也可以通過物聯網與其他物聯網設備連接。
如圖1所示，物聯網設備100可以利用OTA(Over-the-Air Technology，空中下載技術)進行遠端升級。例如，物聯網設備100可以通過網路從伺服器200獲取更新檔，以實現物聯網設備100的遠端升級。其中網路可以是但不限於無線通訊網路、網際網路、私域網、區域網路、都會區網路、廣域網路或是蜂巢式資料網路等。
在物聯網設備100利用OTA進行遠端升級的過程中，不可避免地會出現因升級檔錯誤或其他原因導致升級失敗的情況發生。
為了使得系統升級失敗時，物聯網設備100能夠自動回滾到之前的版本，不影響設備的正常使用，本揭露提出了一種支援升級失敗自動回滾到之前版本的系統升級方案。本揭露主要是設置引導載入程式，基於引導載入程式引導系統升級並提供升級失敗情況下的應對處理。本揭露述及的引導載入程式可以視為設備加電後運行的第一段軟體代碼，其中引導載入程式可以實現為一種韌體，例如可以是Bootloader韌體。
物聯網設備上電啟動後，可以首先啟動引導載入程式，由引導載入程式執行本揭露的系統升級方法，實現系統升級及升級失敗情況下的應對處理。
圖2示出了物聯網設備的儲存區佈局結構示意圖。
如圖2所示，物聯網設備的儲存區可以劃分為第一區、第二區、第三區以及第四區。其中這裡述及的劃分不代表執行實際的劃分動作，而可以是指邏輯上的劃分。
第一區用於儲存引導載入程式，引導載入程式用於執行本揭露的系統升級方法，引導啟動整個系統。
第二區用於儲存第一系統，第三區用於儲存第二系統，其中第二系統為待升級的新系統，第一系統的版本低於第二系統，第一系統可以視為舊系統。第一系統可以是指升級新系統前設備運行過的系統，第二區可以儲存一個或多個版本低於第二系統的舊系統。
第四區用於儲存升級標識、升級次數等升級參數。其中，第四區定義的參數設計為引導載入程式和系統程式進行共用的資料橋樑，可以相互配合完成對系統啟動失敗的自動判斷。
作為示例，在新系統成功啟動後，可以將第二區中的舊系統替換為新系統，並清空第三區，以等待新的升級系統的到來。
另外在新系統成功啟動後，也可以在不刪除第二區中儲存的舊系統的情況下，將新系統添加到第二區，由此第二區中可以儲存多個設備運行過的系統。
圖3示出了根據本揭露一實施例的物聯網設備中的系統升級方法的示意性流程圖。
如圖3所示，物聯網設備上電啟動後，首先啟動引導載入程式，在引導載入程式的引導作用下，實現整個系統升級方法的執行。
在步驟S110，可以由引導載入程式設置計時器，也即初始化計時器。
計時器用於計時，並回應於計時超過預定臨限值(為了便於分區，可以稱為第二預定臨限值)觸發本揭露的系統升級方法的執行(也即觸發引導載入程式的重啟)，或者觸發第一系統的啟動。其中計時器可以實現為一種硬體模組，如可以實現為硬體看門狗。
在本實施例中，第一系統可以是升級前運行的系統，如可以是第二系統的上一個版本的系統。另外第一系統也可以是從第二系統之前多個版本的系統中選擇的一個版本的系統，也即第一系統可以是從第二區儲存的多個舊系統中選擇的一個系統。
在步驟S120，檢查是否存在升級標識。
升級標識用於表徵物聯網設備當前是否存在升級需求，升級標識可以是回應於接收到伺服器下發的升級檔或升級指令而產生的識別字。關於升級標識的具體表示形式，本揭露不再贅述。
在不存在升級標識的情況下，表明物聯網設備當前無需升級，可以執行步驟S190，啟動第一系統。作為示例，在執行步驟S190時，可以啟動升級前運行的系統，也可以根據統計得到的各個版本的系統穩定性，從第二系統之前多個版本的系統中選擇穩定性較好的版本的系統進行啟動。
在存在升級標識的情況下，表明物聯網設備當前存在升級需求，可以執行步驟S130，判斷升級次數是否超過預定臨限值N(為了便於分區，可以稱為第一預定臨限值)。此處述及的升級次數是指嘗試啟動待升級的新系統的次數，也即失敗次數。第一預定臨限值的大小可以根據實際情況設定。
如上文結合圖1所述，第四區用於儲存升級標識、升級次數等參數，因此在執行步驟S120、步驟S130時，均可以從第四區獲取升級標識、升級次數，實現升級標識的尋找、升級次數的判斷等操作。
在判定升級次數超過第一預定臨限值的情況下，表明失敗次數過多，無法升級成功，此時可以執行步驟S190，啟動第一系統。
在判定升級次數不超過第一預定臨限值的情況下，可以執行步驟S140、步驟S150，將升級次數加1並嘗試啟動新系統。
在執行完步驟S150後，可以判斷是否成功啟動。
在第二系統能夠正常運行的情況下可以認為啟動成功，也即升級成功。在第二系統啟動過程中出錯(如拋出錯誤)或者啟動耗時(也即升級耗時)超過第三預定臨限值的情況下，可以認為啟動失敗。
在未成功啟動新系統的情況下，可以執行步驟S195，使計時器超時，進而觸發引導載入程式的重新開機。可選地，在未成功啟動的情況下，也可以通過執行步驟S195使計時器超時，觸發第一系統的啟動。
在成功啟動新系統的情況下，可以執行步驟S170，迴圈執行如下操作：在計時器的計時超過第二預定臨限值之前，重置計時。通過迴圈對計時器的計時清零，可以避免在新系統能夠正常運行的情況下，因計時器超時而重啟引導載入程式或回滾到第一系統。其中，在計時器是看門狗的情況下，步驟S170也即對看門狗進行自動餵狗。可選地，步驟S170可以由成功啟動後的新系統執行。
在本揭露中，可以在計時器的配合下實現系統升級失敗情況下本揭露的系統升級方法(也即引導載入程式)的重啟。可選地計時器還可以用於在第二系統的啟動耗時超過第二預定臨限值的情況下，自動回滾到第一系統。
另外在成功啟動的情況下，還可以執行步驟S180，清除升級標識及/或升級次數。由此，在執行完步驟S180後，成功啟動後的新系統就可以作為當前運行系統運行，此後在物聯網設備需要再次升級的情況下，當前運行的系統可以作為第一系統，待升級的新系統可以作為新的第二系統，再次執行圖3所示的流程，實現系統升級。
綜上，本揭露可以在引導載入程式的作用下初始化計時器，並引導啟動新系統，在成功啟動新系統後，可以迴圈重置計時器的計時，避免系統重啟。而在新系統啟動失敗時，可以由計時器觸發系統重啟，重新在引導載入程式的作用下執行本揭露的升級方法，在失敗次數(也即升級次數)超過第一預定臨限值時，自動回滾到舊系統。
本揭露還提出了另一種物聯網設備中的系統升級方法，包括：設置引導載入程式，引導載入程式被配置為：執行上文結合圖3所示的系統升級方法。
本揭露還提出了另一種物聯網設備中的系統升級方法，包括：回應於系統升級請求，嘗試啟動第二系統；在第二系統啟動失敗或者第二系統啟動失敗次數超過第一預定臨限值的情況下，啟動第一系統。關於第一系統、第二系統可以參見上文相關描述，此處不再贅述。系統升級請求也即物聯網設備的系統升級需求，可以通過檢查是否存在升級標識的方式判斷是否存在系統升級需求，關於升級標識可以參見上文相關描述，此處也不再贅述。
在第二系統啟動失敗的情況下，可以將失敗次數(也即上文述及的啟動次數)加1，然後再次嘗試啟動第二系統，如此在失敗次數超過第一預定臨限值時，不再嘗試啟動第二系統，而是啟動第一系統。
在本實施例中，可以在第二系統超過第三預定臨限值未啟動成功的情況下，判定第二系統啟動失敗。也即本揭露可以根據第二系統啟動耗時來觸發重新升級或回滾到第一系統。
作為示例，可以通過設置計時器，來實現系統第二系統啟動失敗或者第二系統啟動失敗次數超過預定臨限值時，自動回滾到第一系統。例如，計時器可以被設置為，回應於計時超過第二預定臨限值，觸發第一系統的啟動，引導載入程式可以在啟動第二系統失敗或者失敗次數超過第一預定臨限值時，使計時器超時，以回滾到第一系統。
以物聯網設備為快件跟蹤掃描記錄儀、移動POS機為例，上文述及的第一系統/第二系統可以是指即時作業系統(RTOS)。RTOS是指當外界事件或資料產生時，能夠接受並以足夠快的速度予以處理，其處理的結果又能在規定的時間之內來控制生產過程或對處理系統作出快速回應，並控制所有即時任務協調一致運行的作業系統。
至此，就本揭露的物聯網設備中的系統升級方法做了詳細說明。本揭露還可以實現為一種針對物聯網設備中的其他非系統程式的升級的程式升級方法。也即上文述及的第一系統/第二系統也可以替換為運行在物聯網設備中的第一程式/第二程式。

Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the disclosure more thorough and complete, and to fully convey the scope of the disclosure to those skilled in the art.
Figure 1 shows a flow chart of communication between IoT devices and servers.
The IoT device 100 mentioned in this disclosure can be, but is not limited to, a PDA (Personal Digital Assistant, personal digital assistant) smart terminal, a vehicle (such as an unmanned car), a sensor, a smart home device (such as, but not limited to, smart Speakers, sweeping robots, smart bulbs, smart switches, smart door locks, etc. Among them, the PDA smart terminal can be, but is not limited to, a shipment tracking and scanning recorder, a mobile POS machine used to implement one or more functions such as retail billing, printing of small receipts, inventory, data uploading, and daily settlement.
Internet of Things (Internet of Things, referred to as IoT), that is, the "Internet of Things Connected" is an extension and expansion network based on the Internet, which is formed by combining various information sensing devices with the Internet. The huge network realizes the interconnection of people, machines and things at any time and any place. The Internet of Things device 100 may communicate with a server through the Internet of Things, and may also be connected with other Internet of Things devices through the Internet of Things.
As shown in FIG. 1, the Internet of Things device 100 can use OTA (Over-the-Air Technology, over-the-air technology) for remote upgrade. For example, the Internet of Things device 100 may obtain an update file from the server 200 through the network, so as to realize the remote upgrade of the Internet of Things device 100. The network can be, but is not limited to, a wireless communication network, the Internet, a private area network, a local area network, a metropolitan area network, a wide area network, or a cellular data network.
In the process of remote upgrade of the Internet of Things device 100 using OTA, it is inevitable that the upgrade will fail due to an upgrade file error or other reasons.
In order to enable the IoT device 100 to automatically roll back to the previous version when the system upgrade fails, without affecting the normal use of the device, this disclosure proposes a system upgrade solution that supports the automatic rollback of the upgrade failure to the previous version. This disclosure is mainly to set up a boot loader, based on the boot loader to guide the system upgrade and provide response processing in the case of an upgrade failure. The boot loader mentioned in this disclosure can be regarded as the first piece of software code that runs after the device is powered on, and the boot loader can be implemented as a kind of firmware, such as a bootloader firmware.
After the Internet of Things device is powered on and started, the boot loader can be started first, and the boot loader executes the disclosed system upgrade method to realize the system upgrade and the handling in case of failure of the upgrade.
Figure 2 shows a schematic diagram of the layout structure of the storage area of the Internet of Things device.
As shown in Figure 2, the storage area of the IoT device can be divided into a first area, a second area, a third area, and a fourth area. The division mentioned here does not represent the execution of the actual division action, but may refer to the logical division.
The first area is used to store the boot loader, and the boot loader is used to execute the disclosed system upgrade method to boot the entire system.
The second area is used to store the first system, and the third area is used to store the second system. The second system is a new system to be upgraded. The version of the first system is lower than that of the second system. The first system can be regarded as the old system. . The first system can refer to the system where the equipment has been running before the new system is upgraded, and the second area can store one or more old systems whose versions are lower than the second system.
The fourth area is used to store upgrade parameters such as upgrade identification and upgrade times. Among them, the parameters defined in the fourth area are designed as a data bridge shared by the boot loader and the system program, which can cooperate with each other to complete the automatic judgment of the system startup failure.
As an example, after the new system is successfully started, the old system in the second zone can be replaced with the new system, and the third zone can be cleared to wait for the arrival of the new upgraded system.
In addition, after the new system is successfully started, the new system can also be added to the second area without deleting the old system stored in the second area, so that the second area can store systems that have been run by multiple devices.
Fig. 3 shows a schematic flowchart of a system upgrade method in an Internet of Things device according to an embodiment of the present disclosure.
As shown in Figure 3, after the Internet of Things device is powered on, the boot loader is first started, and under the guidance of the boot loader, the implementation of the entire system upgrade method is realized.
In step S110, the timer can be set by the boot loader, that is, the timer is initialized.
The timer is used for timing, and in response to the timing exceeding a predetermined threshold (for ease of partitioning, it may be referred to as the second predetermined threshold) triggers the execution of the system upgrade method of the present disclosure (that is, triggers the restart of the boot loader), Or trigger the activation of the first system. The timer can be implemented as a hardware module, such as a hardware watchdog.
In this embodiment, the first system may be a system running before the upgrade, for example, it may be a system of the previous version of the second system. In addition, the first system may also be a system of a version selected from multiple versions of systems before the second system, that is, the first system may be a system selected from a plurality of old systems stored in the second area.
In step S120, it is checked whether there is an upgrade identifier.
The upgrade identifier is used to characterize whether there is a current upgrade requirement for the Internet of Things device, and the upgrade identifier may be an identifier generated in response to receiving an upgrade file or an upgrade instruction issued by the server. Regarding the specific representation form of the upgrade logo, this disclosure will not repeat it.
In the case that there is no upgrade identifier, it indicates that the IoT device does not currently need to be upgraded, and step S190 may be executed to start the first system. As an example, when step S190 is performed, the system that was running before the upgrade can be started, or the system with better stability can be selected from the systems of multiple versions before the second system according to the system stability of each version obtained by statistics. Start up.
If there is an upgrade identifier, it indicates that the IoT device currently has upgrade requirements, and step S130 can be executed to determine whether the number of upgrades exceeds a predetermined threshold N (for ease of partitioning, it may be referred to as a first predetermined threshold). The number of upgrades mentioned here refers to the number of attempts to start the new system to be upgraded, that is, the number of failures. The size of the first predetermined threshold can be set according to actual conditions.
As described above in conjunction with Figure 1, the fourth area is used to store parameters such as the upgrade identifier and the number of upgrades. Therefore, when step S120 and step S130 are performed, the upgrade identifier and the number of upgrades can be obtained from the fourth area to realize the search for the upgrade identifier. , Judging the number of upgrades and other operations.
In the case where it is determined that the number of upgrades exceeds the first predetermined threshold, it indicates that the number of failures is too many and the upgrade cannot be successful. In this case, step S190 may be executed to start the first system.
In the case where it is determined that the number of upgrades does not exceed the first predetermined threshold, step S140 and step S150 can be executed to increase the number of upgrades by 1 and try to start the new system.
After step S150 is executed, it can be judged whether the startup is successful.
In the case that the second system can run normally, it can be considered that the startup is successful, that is, the upgrade is successful. In the case that an error occurs during the startup of the second system (for example, an error is thrown) or the startup time (that is, the upgrade time) exceeds the third predetermined threshold, the startup may be regarded as a failure.
In the case that the new system is not successfully started, step S195 can be executed to cause the timer to time out, thereby triggering the reboot of the boot loader. Optionally, in the case of unsuccessful startup, the timer can also be timed out by executing step S195 to trigger the startup of the first system.
In the case that the new system is successfully started, step S170 may be executed, and the following operations are performed in a loop: reset the timing before the timing of the timer exceeds the second predetermined threshold. By resetting the timer's timing through the loop, it can avoid restarting the boot loader or rolling back to the first system due to the timer's timeout when the new system can run normally. Wherein, when the timer is a watchdog, step S170 is to automatically feed the watchdog. Optionally, step S170 may be executed by the new system after successful startup.
In the present disclosure, the system upgrade method (that is, the boot loader) of the present disclosure can be restarted when the system upgrade fails with the cooperation of a timer. Optionally, the timer can also be used to automatically roll back to the first system in the case that the startup time of the second system exceeds the second predetermined threshold.
In addition, in the case of successful startup, step S180 may also be executed to clear the upgrade identifier and/or the number of upgrades. Therefore, after performing step S180, the new system after successful startup can be run as the current running system. After that, if the IoT device needs to be upgraded again, the currently running system can be used as the first system, and the new system to be upgraded The system can be used as a new second system, and the process shown in Figure 3 is executed again to achieve system upgrades.
In summary, this disclosure can initialize the timer under the action of the boot loader and boot the new system. After the new system is successfully started, the timer can be reset in a loop to avoid system restart. When the new system fails to start, the system restart can be triggered by a timer, and the upgrade method of this disclosure is executed again under the action of the boot loader. When the number of failures (that is, the number of upgrades) exceeds the first predetermined threshold, Automatically roll back to the old system.
This disclosure also proposes another system upgrade method in the Internet of Things device, which includes: setting a boot loader, and the boot loader is configured to execute the system upgrade method shown in FIG. 3 above.
This disclosure also proposes another system upgrade method in IoT devices, including: responding to a system upgrade request, attempting to start the second system; when the second system fails to start or the number of times the second system fails to start exceeds a first predetermined threshold In the case, start the first system. For the first system and the second system, please refer to the relevant description above, which will not be repeated here. The system upgrade request is the system upgrade requirement of the IoT device. It can be judged whether there is a system upgrade requirement by checking whether there is an upgrade identifier. For the upgrade identifier, please refer to the relevant description above, which will not be repeated here.
In the case that the second system fails to start, the number of failures (that is, the number of startups mentioned above) can be increased by 1, and then try to start the second system again, so that when the number of failures exceeds the first predetermined threshold, no Try to start the second system again, but start the first system.
In this embodiment, it may be determined that the second system has failed to start when the second system exceeds the third predetermined threshold and fails to start successfully. That is, the present disclosure can trigger a re-upgrade or rollback to the first system according to the time it takes for the second system to start.
As an example, a timer can be set to implement automatic rollback to the first system when the second system fails to start or the number of times the second system fails to start exceeds a predetermined threshold. For example, the timer may be set to trigger the activation of the first system in response to the timing exceeding the second predetermined threshold. The bootloader may fail to activate the second system or the number of failures exceeds the first predetermined threshold, Time out the timer to roll back to the first system.
Taking IoT devices as express tracking and scanning recorders and mobile POS machines as examples, the first system/second system mentioned above may refer to a real-time operating system (RTOS). RTOS means that when external events or data are generated, they can be accepted and processed quickly enough, and the results of the processing can control the production process or respond quickly to the processing system within the specified time, and control all real-time An operating system where tasks are coordinated.
So far, the system upgrade method in the Internet of Things device disclosed in this disclosure has been described in detail. The disclosure can also be implemented as a program upgrade method for upgrading other non-system programs in the Internet of Things device. That is, the first system/second system mentioned above can also be replaced with the first program/second program running in the IoT device.
