Abstract

The invention provides a multi-connected machine group system unit upgrading system, method and device, and the system comprises a multi-connected machine group system; the data service center used for providing an indoor and outdoor unit upgrading program package; and DTU connected with the data service center, connected to a CAN bus of the multi-connected machine group system, and used for acquiring an indoor and outdoor machine upgrading program package from the data service center and distributing the indoor and outdoor machine upgrading program package to the multi-connected machine groupsystem through the CAN bus to carry out indoor and outdoor machine synchronous upgrading. By means of the mode, the technical problem that an existing multi-connected machine group system is low in upgrading efficiency is solved, and the technical effect of simply and efficiently upgrading the multi-connected machine group system is achieved.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a system, method and device for unit upgrade of a multi-connected group system. Background technique [0002] With the continuous development of multi-connection group system technology, there are already some multi-connection group system technologies based on CAN+ bus, that is, the project includes multiple systems, and a single system can include 4 external units and hundreds of internal units. The theoretical application of multi-connected air-conditioning group system units usually does not exceed 16 systems, that is, 64 external units and about 3,200 internal units. For such a large number of cluster system units, how to upgrade the program of the multi-connected cluster system with high efficiency, low cost and high reliability is an urgent problem to be solved. [0003] At present, most of the upgrades for multi-connected single-system units are based on a loca...
