Embodiment 1

[0037] According to the actual deployment of the transmission line network, it is abstracted into a chain wireless network. For details, see figure 1 , a number of sensors are distributed in a chain on the side of the base station. Assuming that the initial state of each sensor is exactly the same, the randomly generated data needs to be sent to the base station. Since the sensors in the chain wireless sensor network are distributed linearly, the sensors with a long distance have to establish links with the base station in a multi-hop manner. Assuming that sensor n needs to transmit data to base station BS, it needs to send the data packet to sensor n+1, sensor n+1 forwards the data packet to sensor n+2, and successively transmits the data packet to base station BS in multiple hops. This simple straight line In the transmission mode, the data generated by sensor n must be forwarded by all other sensors closer to the base station BS before finally reaching the base station, whi...

Embodiment 2

[0073] This embodiment discloses a transmission line sensor network, including a communication master station, a monitoring tower, and a monitoring center; an optical fiber access point is set up on the communication master station, a camera and a sensor are arranged on the monitoring tower, and a connection is established between the sensors The sensor network is formed, and the sensor network is used to communicate with the communication master station, and the communication master station transmits the collected information to the background monitoring center through the power optical cable. The monitoring towers of this embodiment are distributed in a chain on the side of the main communication station. The sensors of this embodiment include a number of sensors for monitoring the arc swing, sag, ice thickness of the transmission line, and the temperature and humidity, wind direction and wind speed of the transmission line environment. sensor.

Abstract

The invention discloses a data transmission method based on a transmission line sensor network and a sensor network thereof, including S10: establishing a connection between sensors based on a communication handshake protocol between sensors, and constructing a sensor network; S20: The sensor network is used to transmit the status information of the transmission line acquired by each sensor to the base station; S30: the base station transmits the status information of the transmission line to the data center.

Description

technical field [0001] The invention relates to the field of wireless mobile communication, in particular to a data transmission method based on a transmission line sensor network and the sensor network. Background technique [0002] Transmission lines have been in a complex operating environment for a long time. Remote monitoring of transmission lines is an important means to grasp the operation status of transmission lines. It can realize the observability of the operation environment of transmission equipment, the monitoring of the whole production process, and the warning of risks. Diagnosis provides technical support. [0003] At present, the online monitoring sensor network of transmission lines is mainly composed of communication master stations, wireless self-organizing master stations, ordinary monitoring towers, and monitoring centers. The communication master station is equipped with optical fiber access points, while only cameras and wireless sensor nodes are in...
