Abstract

The invention relates to the technical field of data transmission, in particular to a data transmission method, device and equipment and a power utilization system.The method comprises the steps that when a controller is in a screensaver state, data are not sent in a unified mode any more, but a data sending node of a first function module is determined according to a preset sending period; and determining a node in the second function module when the data is updated as a data sending node of the second function module so as to complete data sending according to the data sending node. A user can set the first function module and the second function module according to the importance degree of the modules, and data in the second function module is sent only when being updated, so that the data of all the function modules are prevented from being frequently sent in a bus, the power consumption of the controller is reduced, and the communication pressure of the bus is relieved.

Description

Technical field [0001] The present invention relates to the field of data transmission, and more particularly to a transmission method, apparatus, device, and electrical system of data. Background technique [0002] Large electrical systems typically include controllers and multiple controlled work devices, controls between controllers, and work devices typically transmitted over communication bus. During the work, there is a lot of data to convey on the bus, but there is a part of the necessary data, not only increase the communication pressure of the bus, but also increase the controller power consumption. For example, the current data transmission mode of the current large central air conditioner is as follows: Whether it is frequent in operation or operation, hundreds of data will be sent on the bus according to the prescribed cycle; the data is immediately on the bus. Send; single system mode is still transmitted according to the multi-system mode data volume loop. Moreover,...
