Embodiment 1

[0075] Such as figure 1 As shown, this embodiment provides a remote upgrade method for an MCU in a communication device, the communication device includes a communication-connected MCU and a wireless communication module, and the remote upgrade method includes:

[0076] S101. The wireless communication module sends a query request to the cloud server;

[0077] S102. The wireless communication module downloads the MCU upgrade package from the cloud server when receiving the first feedback information sent by the cloud server according to the query request;

[0078] Wherein, the first feedback information is used to indicate that the cloud server stores MCU update information for upgrading the MCU;

[0079] S103, the wireless communication module sends an upgrade instruction to the MCU;

[0080] S104. The MCU analyzes the upgrade instruction and obtains an analysis result, and sends second feedback information to the wireless communication module when the analysis result satis...

Embodiment 2

[0085] Such as figure 2 As shown, the remote upgrade method of the MCU in the communication device of this embodiment is a further improvement on Embodiment 1, specifically:

[0086] Before step S101, it also includes:

[0087] S10101. The MCU sends a trigger instruction to the wireless communication module;

[0088] S10102. The MCU sends the version number information of the MCU to the wireless communication module;

[0089] Wherein, the execution order of steps S10101 and S10102 can be exchanged according to actual requirements.

[0090] Step S101 includes:

[0091] S1011. The wireless communication module sends a query request to the cloud server according to the trigger instruction, and sends the received version number information to the cloud server;

[0092] Step S102 includes:

[0093] S1021. The wireless communication module receives the first feedback message sent by the cloud server when the cloud server inquires and stores MCU update information according to ...

Embodiment 3

[0121] Such as image 3 As shown, this embodiment provides a communication device, including an MCU 1 and a wireless communication module 2 connected in communication.

[0122] The wireless communication module 2 is used to send a query request to the cloud server, and downloads the MCU upgrade package from the cloud server when receiving the first feedback information sent by the cloud server;

[0123] Wherein, the first feedback information is used to indicate that the cloud server stores MCU update information for upgrading the MCU;

[0124] The wireless communication module 2 is used to send an upgrade instruction to the MCU1;

[0125] MCU1 is also used to analyze the upgrade instruction and obtain the analysis result, and send the second feedback information to the wireless communication module when the analysis result meets the preset condition;

[0126] The wireless communication module 2 is also used to send the MCU upgrade package to the MCU1 according to the second...

Abstract

The invention discloses communication equipment and an MCU remote upgrading method thereof, the communication equipment comprises an MCU and a wireless communication module which are in communicationconnection, and the remote upgrading method comprises the following steps: the wireless communication module sends a query request to a cloud server, the MCU upgrade package is downloaded from the cloud server when first feedback information sent by the cloud server according to the query request is received; the wireless communication module sends an upgrading instruction to the MCU; the MCU analyzes the upgrading instruction and obtains an analysis result, and sends second feedback information to the wireless communication module when the analysis result meets a preset condition; the wireless communication module sends the MCU upgrade package to the MCU according to the second feedback information; and the MCU is upgraded according to the received MCU upgrade package. The MCU upgrade package is downloaded from the cloud server through the wireless communication module and transmitted to the MCU, remote online upgrade of the MCU is achieved, remote automatic upgrade of the MCU is achieved, and the MCU upgrade efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a remote upgrade method for communication equipment and its MCU. Background technique [0002] The Microcontroller Unit (MCU for short) is the core component of a communication device (such as an embedded communication device). The mainstream MCU internal program is upgraded through a personal computer (Personal Computer, referred to as PC) using a special burning tool. Therefore, once the MCU program needs to be upgraded, it is necessary to remove the MCU device from the embedded communication device, and then use the PC programming tool to upgrade the MCU; however, this upgrade method has problems such as cumbersome upgrade process and low upgrade efficiency. In addition, when the MCU cannot be removed from the embedded communication device, the MCU cannot be upgraded, so that the MCU must be returned to the factory for each upgrade, resulting in waste of time a...
