具体实施方式detailed description

下面将参照附图更详细地描述本公开的优选实施方式。虽然附图中显示了本公开的优选实施方式，然而应该理解，可以以各种形式实现本公开而不应被这里阐述的实施方式所限制。相反，提供这些实施方式是为了使本公开更加透彻和完整，并且能够将本公开的范围完整地传达给本领域的技术人员。Hereinafter, preferred embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. 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 present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

本公开述及的物联网设备100可以是但不限于PDA(Personal Digital Assistant，个人数字助理)智能终端、车辆(如无人汽车)、传感器、智能家居设备(如可以包括但不限于智能音箱、扫地机器人、智能灯泡、智能开关、智能门锁)等。其中PDA智能终端可以是但不限于快件跟踪扫描记录仪，用于实现零售开单、打印小票、盘点、数据上传和日结等一种或多种功能的移动POS机。The IoT device 100 mentioned in the present 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 scan 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.

物联网(Internet of Things，简称IoT)，即“万物相连的互联网”是互联网基础上的延伸和扩展的网络，将各种信息传感设备与互联网结合起来而形成的一个巨大网络，实现在任何时间、任何地点，人、机、物的互联互通。物联网设备100可以通过物联网与服务器通信，也可以通过物联网与其他物联网设备连接。The Internet of Things (IoT), that is, the "Internet of Everything" is an extended and expanded network based on the Internet. It is a huge network formed by combining various information sensing devices with the Internet. Time, any place, the interconnection of people, machines and things. 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.

如图1所示，物联网设备100可以利用OTA(Over-the-Air Technology，空中下载技术)进行远程升级。例如，物联网设备100可以通过网络从服务器200获取更新文件，以实现物联网设备100的远程升级。其中网络可以是但不限于无线通信网络、因特网、私域网、局域网、城域网、广域网或是蜂窝数据网络等。As shown in FIG. 1, the IoT device 100 can be upgraded remotely by using OTA (Over-the-Air Technology). 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.

在物联网设备100利用OTA进行远程升级的过程中，不可避免地会出现因升级文件错误或其他原因导致升级失败的情况发生。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.

为了使得***升级失败时，物联网设备100能够自动回滚到之前的版本，不影响设备的正常使用，本公开提出了一种支持升级失败自动回滚到之前版本的***升级方案。本公开主要是设置引导加载程序，基于引导加载程序引导***升级并提供升级失败情况下的应对处理。本公开述及的引导加载程序可以视为设备加电后运行的第一段软件代码，其中引导加载程序可以实现为一种固件，例如可以是Bootloader固件。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, the present disclosure proposes a system upgrade solution that supports automatic rollback to the previous version after the upgrade fails. The present disclosure mainly sets up a boot loader, guides the system upgrade based on the boot loader, and provides response processing in the case of an upgrade failure. The boot loader mentioned in the present 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, for example, it can be Bootloader firmware.

物联网设备上电启动后，可以首先启动引导加载程序，由引导加载程序执行本公开的***升级方法，实现***升级及升级失败情况下的应对处理。After the Internet of Things device is powered on and started, the boot loader can be started first, and the boot loader executes the system upgrade method of the present disclosure, so as to realize the system upgrade and the handling processing in the case of failure of the upgrade.

如图2所示，物联网设备的存储区可以划分为第一区、第二区、第三区以及第四区。其中这里述及的划分不代表执行实际的划分动作，而可以是指逻辑上的划分。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.

第一区用于存储引导加载程序，引导加载程序用于执行本公开的***升级方法，引导启动整个***。The first area is used to store a boot loader, and the boot loader is used to execute the system upgrade method of the present disclosure to boot the entire system.

第二区用于存储第一***，第三区用于存储第二***，其中第二***为待升级的新***，第一***的版本低于第二***，第一***可以视为旧***。第一***可以是指升级新***前设备运行过的***，第二区可以存储一个或多个版本低于第二***的旧***。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 may refer to the system where the device has been running before the new system is upgraded, and the second area may store one or more old systems whose versions are lower than the second system.

第四区用于存储升级标识、升级次数等升级参数。其中，第四区定义的参数设计为引导加载程序和***程序进行共享的数据桥梁，可以相互配合完成对***启动失败的自动判断。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 for the boot loader and the system program to share, and can cooperate with each other to complete the automatic judgment of the system startup failure.

作为示例，在新***成功启动后，可以将第二区中的旧***替换为新***，并清空第三区，以等待新的升级***的到来。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.

另外在新***成功启动后，也可以在不删除第二区中存储的旧***的情况下，将新***添加到第二区，由此第二区中可以存储多个设备运行过的***。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.

如图3所示，物联网设备上电启动后，首先启动引导加载程序，在引导加载程序的引导作用下，实现整个***升级方法的执行。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.

在步骤S110，可以由引导加载程序设置定时器，也即初始化定时器。In step S110, the boot loader can set the timer, that is, initialize the timer.

定时器用于计时，并响应于计时超过预定阈值(为了便于分区，可以称为第二预定阈值)触发本公开的***升级方法的执行(也即触发引导加载程序的重启)，或者触发第一***的启动。其中定时器可以实现为一种硬件模块，如可以实现为硬件看门狗。The timer is used for timing, and triggers the execution of the system upgrade method of the present disclosure (that is, triggers the restart of the boot loader) in response to the timing exceeding a predetermined threshold (for ease of partitioning, it may be referred to as the second predetermined threshold), or triggers the first system Start. The timer can be implemented as a hardware module, such as a hardware watchdog.

在本实施例中，第一***可以是升级前运行的***，如可以是第二***的上一个版本的***。另外第一***也可以是从第二***之前多个版本的***中选择的一个版本的***，也即第一***可以是从第二区存储的多个旧***中选择的一个***。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.

在步骤S120，检查是否存在升级标识。In step S120, it is checked whether there is an upgrade identifier.

升级标识用于表征物联网设备当前是否存在升级需求，升级标识可以是响应于接收到服务器下发的升级文件或升级指令而生成的标识符。关于升级标识的具体表示形式，本公开不再赘述。The upgrade identifier is used to characterize whether the IoT device currently has an upgrade requirement, 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 identifier, this disclosure will not repeat it.

在不存在升级标识的情况下，表明物联网设备当前无需升级，可以执行步骤S190，启动第一***。作为示例，在执行步骤S190时，可以启动升级前运行的***，也可以根据统计得到的各个版本的***稳定性，从第二***之前多个版本的***中选择稳定性较好的版本的***进行启动。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.

在存在升级标识的情况下，表明物联网设备当前存在升级需求，可以执行步骤S130，判断升级次数是否超过预定阈值N(为了便于分区，可以称为第一预定阈值)。此处述及的升级次数是指尝试启动待升级的新***的次数，也即失败次数。第一预定阈值的大小可以根据实际情况设定。If there is an upgrade identifier, it indicates that the IoT device currently has upgrade requirements, and step S130 may 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.

如上文结合图1所述，第四区用于存储升级标识、升级次数等参数，因此在执行步骤S120、步骤S130时，均可以从第四区获取升级标识、升级次数，实现升级标识的查找、升级次数的判断等操作。As described above in conjunction with Figure 1, the fourth area is used to store upgrade identification, upgrade times and other parameters. Therefore, when step S120 and step S130 are executed, the upgrade identification and upgrade times can be obtained from the fourth area to realize the search for the upgrade identification. , Judging the number of upgrades and other operations.

在判定升级次数超过第一预定阈值的情况下，表明失败次数过多，无法升级成功，此时可以执行步骤S190，启动第一***。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.

在判定升级次数不超过第一预定阈值的情况下，可以执行步骤S140、步骤S150，将升级次数加1并尝试启动新***。In the case where it is determined that the number of upgrades does not exceed the first predetermined threshold, step S140 and step S150 may be executed to increase the number of upgrades by 1 and try to start the new system.

在执行完步骤S150后，可以执行步骤S160判断是否成功启动。After step S150 is executed, step S160 can be executed to determine whether the startup is successful.

在第二***能够正常运行的情况下可以认为启动成功，也即升级成功。在第二***启动过程中出错(如抛出错误)或者启动耗时(也即升级耗时)超过第三预定阈值的情况下，可以认为启动失败。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.

在未成功启动新***的情况下，可以执行步骤S195，使定时器超时，进而触发引导加载程序的重新启动。可选地，在未成功启动的情况下，也可以通过执行步骤S195使定时器超时，触发第一***的启动。In the case that the new system is not successfully started, step S195 may be executed to cause the timer to time out, thereby triggering the restart 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.

在成功启动新***的情况下，可以执行步骤S170，循环执行如下操作：在定时器的计时超过第二预定阈值之前，重置计时。通过循环对定时器的计时清零，可以避免在新***能够正常运行的情况下，因定时器超时而重启引导加载程序或回滚到第一***。其中，在定时器是看门狗的情况下，步骤S170也即对看门狗进行自动喂狗。可选地，步骤S170可以由成功启动后的新***执行。In the case that the new system is successfully started, step S170 may be executed to cyclically perform the following operations: reset the timing before the timing of the timer exceeds the second predetermined threshold. By cyclically clearing the timer to zero, it is possible to avoid restarting the boot loader or rolling back to the first system due to the timer 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.

在本公开中，可以在定时器的配合下实现***升级失败情况下本公开的***升级方法(也即引导加载程序)的重启。可选地定时器还可以用于在第二***的启动耗时超过第二预定阈值的情况下，自动回滚到第一***。In the present disclosure, the system upgrade method (that is, the boot loader) of the present disclosure can be restarted in the event that the system upgrade fails with the cooperation of the timer. Optionally, the timer may 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.

另外在成功启动的情况下，还可以执行步骤S180，清除升级标识和/或升级次数。由此，在执行完步骤S180后，成功启动后的新***就可以作为当前运行***运行，此后在物联网设备需要再次升级的情况下，当前运行的***可以作为第一***，待升级的新***可以作为新的第二***，再次执行图3所示的流程，实现***升级。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 used as the current operating system. After that, if the IoT device needs to be upgraded again, the currently operating 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.

综上，本公开可以在引导加载程序的作用下初始化定时器，并引导启动新***，在成功启动新***后，可以循环重置定时器的计时，避免***重启。而在新***启动失败时，可以由定时器触发***重启，重新在引导加载程序的作用下执行本公开的升级方法，在失败次数(也即升级次数)超过第一预定阈值时，自动回滚到旧***。In summary, the present 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 cyclically 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 the present disclosure is executed again under the action of the boot loader, and when the number of failures (that is, the number of upgrades) exceeds the first predetermined threshold, it automatically rolls back To the old system.

在本实施例中，可以在第二***超过第三预定阈值未启动成功的情况下，判定第二***启动失败。也即本公开可以根据第二***启动耗时来触发重新升级或回滚到第一***。In this embodiment, it may be determined that the second system fails 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.

作为示例，可以通过设置定时器，来实现***第二***启动失败或者第二***启动失败次数超过预定阈值时，自动回滚到第一***。例如，定时器可以被设置为，响应于计时超过第二预定阈值，触发第一***的启动，引导加载程序可以在启动第二***失败或者失败次数超过第一预定阈值时，使定时器超时，以回滚到第一***。As an example, a timer can be set to realize that the system automatically rolls back 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 start of the first system in response to the timing exceeding the second predetermined threshold, and the bootloader may time out the timer when the second system fails to start or the number of failures exceeds the first predetermined threshold, To roll back to the first system.

以物联网设备为快件跟踪扫描记录仪、移动POS机为例，上文述及的第一***/第二***可以是指实时操作***(RTOS)。RTOS是指当外界事件或数据产生时，能够接受并以足够快的速度予以处理，其处理的结果又能在规定的时间之内来控制生产过程或对处理***作出快速响应，并控制所有实时任务协调一致运行的操作***。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).
