Multi-cascade OTA upgrading device and method for industrial equipment

Abstract

The invention discloses an industrial equipment multi-cascade OTA upgrading device, which is characterized by comprising a communication gateway for network communication, a cloud platform for storing an upgrading program, a slave computer, a host computer for monitoring the firmware version and cascade state of the slave computer, cascade equipment, a controller, a heat energy online platform and an Internet of Things platform, the communication gateway is connected with the host through a wireless network, and the cascade device is connected with the Internet of Things platform through the communication gateway; the OTA upgrading of the multi-split equipment is supported, and the applicability is wide; bootLoader files are supported, and all the files can be downloaded on the cloud platform and downloaded to the corresponding sub-devices through the communication gateway; multi-version firmware uploading and operation recording are supported; various master control ICs are compatible, and the compatibility is wide; and all upgrading is remotely operated, so that the maintenance cost can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of energy monitoring, and in particular relates to a device and method for multi-cascade OTA upgrading of industrial equipment. Background technique [0002] OTA is over the air download technology. It is a necessary function of many embedded products, which can solve problems such as system updates, product function iterations, bug fixes, and security protection. Most energy equipment products do not have OTA functions, and existing gateways cannot meet the upgrade requirements of most equipment, especially in the case of multi-device cascading in the field of energy monitoring, there is no suitable solution. [0003] There are still the following problems in the existing technology: in energy transformation, the original equipment does not have the ability to upgrade, and some manufacturers can only update new functions or correct bugs by updating the firmware on site; it is cumbersome to implement OTA, and even so...

Problems solved by technology

Most energy equipment products do not have OTA functions, and the existing gateways cannot meet the upgrade requirements of most equipment, especially in the case of multi-device cascading in the field of energy monitoring, there is no suitable solution

[0003] There are still the following problems in the existing technology: in energy transformation, the original equipment does not have the ability to upgrade, and some manufacturers can only update new functions or correct bugs by updating the firmware on site; it is cumbersome to implement OTA, and even some product developers no longer maintain it iteratively , even more impossible to achieve; there are many energy controller main control chip manufacturers, it is troublesome to connect them one by one, and it is a waste of manpower; among multi-energy devices, many devices are in the form of networking, and the upgrade service is relatively complicated; currently there is no level 2 for devices or a general solution for multi-level upgrades
