Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] refer to Figure 1 to Figure 5 , a data transmission method of transmission line wireless communication based on an automatic power increase retransmission mechanism, the data transmission method includes the following steps:

[0040] 1) Initial parameter setting:

[0041] Set up a sensor S 1 every T c The data is collected once every minute and uploaded to the central node 1, and each sensor 2 adopts the working method of taking turns in turn;

[0042] Suppose the distance between any two towers is d g m, using a wireless communication module with adjustable transmission power, its maximum power P max At least a radius of 2.5d can be covered g The range of meters; that is to say, a sensor 2 can communicate with up to 5 adjacent central nodes at the same time;

[0043] The communication between the central node 1 and the sensor 2 is carried out through a co...

Abstract

A data transmission method for electric transmission line wireless communication based on an automatic power increasing retransmission mechanism comprises the following steps that firstly, initial parameters are set, sensors are set to collect data one time every other Tc minutes and upload the data to a central node, and the sensors take turns to work circularly; a power increasing coefficient alpha1, a power increasing coefficient alpha 2 and a power increasing coefficient alpha 3 are set, wherein 0<alpha1<alpha 2< alpha 3<1, and the sensor transmitting power maximum value is Pmax; secondly, the communication establishing process of the sensor S1 and the central node comprises the steps that 2.1, when the S1 uploads the data to the central node, the automatic power increasing retransmission mechanism is adopted; 2.2, the communication establishing processes of the sensor S2, the sensor S3,...and the sensor Sn and the central node is like the establishing process of the first step. According to the data transmission method, the reliability can be improved, and the fluency can be enhanced.

Description

technical field [0001] The invention relates to a data transmission method for transmission line wireless communication. Background technique [0002] The data transmission system architecture of transmission line wireless communication is divided into three parts: sensor, central node, and background. [0003] In practical applications, the arrangement of utility poles and towers is generally linear. Sensors are placed on each transmission line of each tower, and a central node is also placed on the tower. The distance between the two towers is generally between 100 and 200 meters. Without loss of generality, suppose the distance between any two towers is d g meters; then five consecutive towers A, B, C, D, E are respectively separated by d g ,Such as figure 1 As shown, the distance between towers d g It is 200m. In this patent, a wireless communication module with adjustable transmission power is adopted, and its maximum power P max At least a radius of 2.5d can be...
