Embodiment Construction

[0023] Such as figure 1 As shown, the overall structural composition of the present invention is described. The structure includes sensors, signal processors, data receivers, and host computer monitoring servers; among them, the host computer monitoring server is connected to several data receivers by wire, each data receiver communicates wirelessly with several signal processors, and the signal processor Wired to the sensor.

[0024] One or more sensors on each monitoring device collects the vibration signal of the device in real time, which is processed and packaged by the signal processor on the device and then sent infinitely. After being received by the signal receiver, it is uploaded to the monitoring server of the host computer, which is convenient for the staff Check the working condition of wind power equipment.

[0025] Such as figure 2 Shown is the block diagram of the signal processor and receiver.

[0026] The signal processor includes: signal processing core...

Abstract

The invention discloses a long-distance sensing network node oriented to offshore wind power system state monitoring and a method. The node includes signal processors and signal receivers. The signal processors collect the equipment operational condition key data acquired by a sensor installed at a key position of offshore wind power main equipment to perform FPGA processing. The data are then loaded to a 2.4GHz frequency channel. After amplification by a power amplification module and a high-power antenna, and ultra long-distance transmission, processed data signals can reach the signal receivers placed onshore. The signal receivers transmit the received signals to an upper computer, so that monitoring personnel can monitor the equipment working state. With no need for building of a base station and other large infrastructure construction, ultra long-distance data transmission can be realized. The node and the method provided in the invention can be used by the monitoring personnel of wind power systems, so that they can find and eliminate faults as early as possible, and the workload of inspection tour personnel can be greatly reduced.

Description

technical field [0001] The invention relates to a long-distance data transmission technology, in particular to a long-distance sensor network node and method for state monitoring of an offshore wind power system. Background technique [0002] The wind power generation equipment in the offshore wind power system has been in harsh environments such as humidity, low temperature, strong wind, and sun exposure at sea for a long time. These harsh conditions always test the normal operation of the equipment, which has an important impact on the normal power generation of the wind power system. [0003] Given that its harsh environment is not suitable for manual work, an automated detection solution is needed to detect the status of wind power equipment. [0004] At the same time, there are many state parameters of each device. If collected in real time, the amount of data collected by the sensor is very large, which brings great difficulties to wireless transmission. [0005] Ther...
