本发明涉及设备升级技术领域，尤其涉及一种远程升级系统。The present invention relates to the field of device upgrade technologies, and in particular, to a remote upgrade system.
目前，嵌入式设备由于具有低成本和高可靠性的特点，被广泛应用在网络通信、工业控制和安防系统等领域。嵌入式设备通常是一种面向特定应用而设计开发的设备，可包括一用于终端设备正常运行时所用到的操作系统以及应用程序的业务应用模块，该业务应用模块可实现终端设备的业务功能以及升级功能，其中，升级功能是指可在互联网上下载新的业务应用模块并烧写新的业务应用模块覆盖原来的业务应用模块的功能。在实际应用中，嵌入式设备需要升级更新业务应用模块，从而达到功能增强或者修正功能缺陷的目的。At present, embedded devices are widely used in network communication, industrial control and security systems due to their low cost and high reliability. An embedded device is usually a device designed and developed for a specific application, and may include a service application module for an operating system and an application used when the terminal device is in normal operation, and the service application module may implement a service function of the terminal device. And an upgrade function, wherein the upgrade function refers to a function of downloading a new business application module on the Internet and burning a new business application module to cover the original business application module. In practical applications, the embedded device needs to upgrade and update the business application module to achieve the purpose of enhancing functions or correcting functional defects.
在实现远程升级功能的过程中，可能遇到升级异常的情况，例如
在自动升级时若产生掉电或者用户晚上睡前断电，会导致终端设备升级失败，这时业务应用模块就会不完整或者被破坏，使得嵌入式设备无法正常运行。且在升级过程中由于系统暂停工作，在用户不知情的状况下网络中止使用，会影响用户的使用。现有技术中，一般采用业务应用模块冗余双备份的容错方法，即在设备中设置两个业务应用模块，当主用的业务应用模块损坏，则由备用的业务应用模块替代运行，以保证设备正常可用。但是在设备中保存两个业务应用模块，会使得储存空间成倍的增加，增加了设备的成本。In the process of implementing the remote upgrade function, you may encounter an upgrade exception, such as
If the power is lost during the automatic upgrade or the user loses power before going to bed at night, the upgrade of the terminal device will fail. At this time, the service application module will be incomplete or damaged, and the embedded device will not operate normally. In the upgrade process, due to the suspension of the system, the network will be suspended without the user's knowledge, which will affect the user's use. In the prior art, a fault-tolerant method for redundant dual backup of a service application module is generally adopted, that is, two service application modules are set in the device. When the service application module of the primary service is damaged, the standby service application module is replaced by the operation to ensure the device. Normally available. However, saving two business application modules in the device will double the storage space and increase the cost of the device.

在本实施例中，电解电容是储能电容，用于对负载放电，当输入电压降低时，通过电解电容对负载放电，降低输入电压骤降引起电源欠压导致的系统不稳现象。当12V直流电源断电后12V电压会慢慢掉电影响供电电压，直到供电电压有趋势降到低于5V，由于USB接口输入5V直流电源使得第二二极管D2快速导通，当第二二极管D2的导通时，第一二极管D1进入反向截止状态，防止USB接口输入5V直流电源漏电；第二二极管D2导通后，对电解电容充电，使供电电压维持5V，终端设备仍能正常工作，达到在升级过程中不会因断电而受影响的目的。In this embodiment, the electrolytic capacitor is a storage capacitor for discharging the load. When the input voltage is lowered, the capacitor is discharged through the electrolytic capacitor to reduce the instability of the system caused by the undervoltage of the power supply caused by the sudden drop of the input voltage. When the 12V DC power supply is cut off, the 12V voltage will gradually lose power and affect the power supply voltage until the power supply voltage has a tendency to drop below 5V. Because the USB interface inputs 5V DC power, the second diode D2 turns on quickly, when the second When the diode D2 is turned on, the first diode D1 enters a reverse-off state to prevent the USB interface from inputting a 5V DC power supply leakage; after the second diode D2 is turned on, the electrolytic capacitor is charged to maintain the power supply voltage at 5V. The terminal equipment can still work normally, and it will not be affected by power failure during the upgrade process.
