Problems solved by technology

[0005] All nodes in the network are in the working state, but some nodes in the network may not need to work, which causes unnecessary fuel consumption
For example, when the car needs to be charged, all the nodes on the car are awakened, and only the node responsible for charging needs to work, while other nodes such as the node responsible for the air conditioner do not need to work, and the node responsible for the air conditioner also enters the working state, so cause unnecessary fuel consumption

Embodiment 1

[0053] The embodiment of the present invention provides a method for waking up a node, see figure 1 , where the method includes:

[0054] Step 101: In the dormant state, receive the first network management message sent by the first node in the network, the first network management message carries the wake-up identifier and the group where the first node is located;

[0055] Step 102: Determine according to the wake-up identifier that the first network management message is used to wake up the second node;

[0056] Step 103: Obtain the stored group where the second node is located;

[0057] Step 104: judging whether the group where the first node is located is the same as the group where the second node is located;

[0058] Step 105: If they are the same, determine that the first node and the second node are in the same group, and wake up the second node.

[0059] Preferably, after waking up the second node, it also includes:

[0060] receiving a second network management ...

Embodiment 2

[0075] The embodiment of the present invention provides a method for waking up a node, see figure 2 , where the method includes:

[0076] Step 201: Group the nodes in the network according to the functional requirements of electronic appliances;

[0077] Specifically, under the KL30 (normal fire) condition, the nodes in the network are grouped according to the functional requirements of electronic appliances and the function of each node in the network.

[0078] Among them, nodes in the same group have the same function, and a node can belong to multiple groups at the same time.

[0079] The executor of the embodiment of the present invention can be the second node, and the second node can be any node in the network, that is, this step can be to group the nodes in the network according to the functional requirements of electronic appliances to obtain the node where the second node is located. grouping.

[0080] For example, nodes in the network include TBOX, BMS, VCU, CLM,...

Embodiment 3

[0134] An embodiment of the present invention provides a device for waking up a node, see image 3 , where the device includes:

[0135] The first receiving module 301 is configured to receive a first network management message sent by a first node in the network in a dormant state, where the first network management message carries a wake-up identifier and a group where the first node is located;

[0136] The first determining module 302 is configured to determine according to the wake-up identifier that the first network management message is used to wake up the second node;

[0137] An acquisition module 303, configured to acquire the stored group where the second node is located;

[0138] The first judging module 304 is configured to judge whether the group where the first node is located is the same as the group where the second node is located;

[0139] A wake-up module 305, configured to, if they are the same, determine that the first node and the second node are in t...

Abstract

The invention discloses a method and device for node rousing and belongs to the field of electric networks. The method comprises the steps that in a dormant state, a first webmaster message sent by a first node in a network is received, and the first webmaster message carries a rousing mark and a group where the first node is placed; according to the rousing mark, the first webmaster message is determined and is used for rousing a second node; a stored group where the second node is placed is obtained; whether the groups where the first node and the second node are placed are the same is judged; and if yes, the fact that the first node and the second node are in the same group is determined, and the second node is roused. The device comprises a first receiving module, a first determining module, an obtaining module, a first judging module and a rousing module. Only nodes in the same group are roused, and accordingly unnecessary fuel consumption is lowered.

Description

technical field [0001] The invention relates to the field of electrical networks, in particular to a method and device for waking up a node. Background technique [0002] With the improvement of people's living standards and quality of life, cars have become the main tool for people to travel; the network of cars includes multiple nodes, and each node plays a different role. When the node does not need to work, the node enters the dormant state; when the node enters the working state, it needs to wake up the node. [0003] The prior art provides a method for waking up a node, which can be as follows: when the node is about to enter the working state, the micro control unit of the car sends a wake-up request to all nodes in the network; all nodes in the network receive the micro control unit When a wake-up request is sent, it enters the working state. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problem...
