Embodiment 1

[0071] figure 1 It is an exemplary flowchart of a method for controlling power consumption of a bus system provided by Embodiment 1 of the present invention. The bus system includes a bus control device and multiple nodes on the bus, and the multiple nodes are divided into two or more groups; the method is used for the bus control device.

[0072] see figure 1 As shown, the method may include:

[0073] S101. Send the initial setting information by broadcasting, so that each group starts to alternately enter the working state to become a working group or enter the dormant state to become a dormant group, wherein the initial setting information includes: each group sequentially becomes the sequence number of the working group, the working group The preset working hours and the number of said groups.

[0074] The basic idea of ​​this embodiment is: first divide all nodes on the bus into multiple groups, and these groups alternately enter the working state and the sleeping stat...

Embodiment 2

[0103] figure 2 It is an exemplary flowchart of a method for controlling power consumption of a bus system provided by Embodiment 2 of the present invention. The bus system includes a bus control device and multiple nodes on the bus, and the multiple nodes are divided into two or more groups; this embodiment corresponds to the previous embodiment, and this method is used for nodes.

[0104] see figure 2 As shown, the method may include:

[0105] S201. Receive the initial setting information sent by the bus control device, wherein the initial setting information includes: the sequence numbers in which each group becomes a working group, the preset working time of the working group, and the number of the groups.

[0106] S202. Obtain the time duration that the current node should be in the dormant state according to the initial setting information.

[0107] For example, in the example of "Group 1, Group 2, and Group 3" mentioned in the previous embodiment, the nodes in the ...

Embodiment 3

[0125] The present invention will be further described below in combination with specific scenarios.

[0126] image 3 It is an exemplary flow chart of a method for controlling power consumption of a bus system provided by Embodiment 3 of the present invention. This embodiment corresponds to the above-mentioned embodiments. In this embodiment, the bus system is specifically a 485 bus system, and the bus control device is specifically a host computer.

[0127] S301. The host computer groups the nodes in the bus system.

[0128] For example, the nodes can be divided into m groups, and each node has its own identification number, which is incremented by one according to the distance from the host computer from near to far. The grouping rules can be: Group 1 includes nodes with ID numbers 1, 1+m, 1+2m..., Group 2 includes nodes with ID numbers 2, 2+m, 2+2m..., Group 3 It includes nodes with identification numbers 3, 3+m, 3+2m..., and the mth group includes nodes with identific...

Abstract

The invention relates to the technical field of distributed communication systems, and provides a bus system power consumption control method and device. When the method is used for bus control equipment, the method comprises the steps that initial setting information is transmitted in a broadcasting mode so that all node groups are enabled to start entering the working state or the dormancy state alternately; and time synchronization information is periodically transmitted in the broadcasting mode so that the nodes in working groups are enabled to correct dormancy countdown of the nodes according to the received time synchronization information. All the groups are enabled to the switched between the working state and the dormancy state via the aforementioned time-sharing dormancy mechanism so as to ensure that only a part of nodes are in the working state at the same time and the rest nodes enter the dormancy state, and time synchronization with the bus control device is realized by receiving the time synchronization information of the bus control device. The cumulatively generated time errors on all the nodes are eliminated by a time synchronization mechanism so that time synchronization can be ensured and thus the beneficial effects that total power consumption of the system is reduced and communication quality is guaranteed can be achieved.

Description

technical field [0001] Embodiments of the present invention generally relate to the technical field of distributed communication systems, and in particular, relate to a method and device for controlling power consumption of a bus system. Background technique [0002] In a distributed communication system, such as a 485 bus system, there is often a contradiction between the number of nodes and the total power of the system: on the one hand, in order to realize the predetermined function, it is often necessary to distribute many nodes; Power usually has a rated value, that is, the sum of node power consumption will be limited, so the number of nodes should not be too large, otherwise it will cause the problem of excessive system load. [0003] In the existing technology, in order to overcome the above contradictions, one way is to increase the rated power of the system so that more nodes can be accommodated. However, in many practical application scenarios (for example, for sa...
