specific Embodiment approach 1

[0025] The specific embodiment one, electric vehicle remote communication method under heterogeneous network, it comprises the following steps:

[0026] Step 1. Store the wireless network layout of each community and the historical data of the signal strength of various wireless networks in the control center, and list them in order from strong to weak;

[0027] Step 2. Within a time period, divide all monitored electric vehicles into N clusters with a radius of rb; N is a positive integer; each monitored electric vehicle is recorded as a node AP;

[0028] Each cluster includes several node APs, and a node AP only belongs to one cluster, which is recorded as a cluster member;

[0029] A cluster head is jointly recommended by all cluster members in a cluster, and all cluster members can communicate with the cluster head;

[0030] All cluster heads can communicate with the control center, and cluster members cannot communicate with the control center;

[0031] Step 3, within t...

specific Embodiment approach 2

[0038] Embodiment 2. This embodiment is a further limitation of the electric vehicle remote communication method under the heterogeneous network described in Embodiment 1. If a node AP is located within the radius of multiple clusters at the same time, the cluster members will randomly join any of them. a cluster.

specific Embodiment approach 3

[0039] Embodiment 3. This embodiment is a further limitation of the electric vehicle remote communication method under the heterogeneous network described in Embodiment 2. If the cluster head of a cluster exits a cluster, all remaining cluster members of the cluster will be re-elected A cluster head, which reports the information that it is elected as the cluster head to the control center.

Abstract

The invention provides an electric automobile remote communication method under a heterogeneous network, relates to the electric automobile remote communication technology under the heterogeneous network, and is to solve the problem of poor communication reliability in the remote communication process of an electric automobile and a control center. The method is characterized in that wireless network signals of different cells are listed according to historical data; and when the electric automobile passing by a cell has a communication demand, the control center assigns a signal-strongest network according to the historical data to enable the electric automobile to realize wireless communication. The method enables the number of electric automobiles connected to the control center to be reduced through the cluster technology to improve processing speed of the control center; communication reliability is greatly improved; and the method is suitable for occasions of remote communication of the electric automobiles.

Description

technical field [0001] The invention relates to the electric vehicle remote communication technology under the heterogeneous network. Background technique [0002] At present, electric vehicles can be used in a large area. At present, electric vehicles can be equipped with communication terminals as needed to realize remote and real-time communication with the control center. However, since electric vehicles will always be in operation, the reliability of communication is still low due to differences in signal conditions. Contents of the invention [0003] The invention aims to solve the problem of poor communication reliability in the long-distance communication process between an electric vehicle and a control center, thereby providing a long-distance communication method for an electric vehicle under a heterogeneous network. [0004] A remote communication method for an electric vehicle under a heterogeneous network, comprising the following steps: [0005] Step 1. St...
