Optical communication wake-up-based optical fiber network sensor, optical communication wake-up-based optical fiber network sensor monitoring system and monitoring method thereof

Abstract

The present invention discloses an optical communication wake-up-based optical fiber network sensor, an optical communication wake-up-based optical fiber network sensor monitoring system and a monitoring method thereof. The optical communication wake-up-based optical fiber network sensor comprises a power supply module, a continuous working module and a discontinuous working module. The power supply module supplies power to the continuous working module and the discontinuous working module simultaneously, and the continuous working module is used to detect an optical fiber reception signal and a sensor monitoring signal. When any one of the two signals is triggered, the discontinuous working module is turned on, and is turned off after the data acquisition and transmission, thereby entering a power-saving mode. The optical communication wake-up-based optical fiber network sensor, the optical communication wake-up-based optical fiber network sensor monitoring system and the monitoring method thereof can be applied to the severe application environments, and are long in communication distance, high in reliability and small in power consumption.

Description

technical field [0001] The invention belongs to the field of sensor measurement and monitoring, and in particular relates to an optical fiber network sensor based on optical communication wakeup, an optical fiber network sensor monitoring system and a monitoring method thereof. Background technique [0002] In recent years, the Internet of Things industry has developed rapidly, and sensors have already penetrated into a wide range of fields such as industrial production, smart home, space development, marine exploration, environmental protection, resource investigation, medical diagnosis, bioengineering, and even cultural relic protection. It can be seen that the sensor technology of the Internet of Things plays a very important role in developing the economy and promoting social progress. [0003] At present, IoT sensors can be classified into wireless sensors and wired sensors according to the communication method: [0004] Wireless sensors can easily build a wireless net...

AI Technical Summary

Problems solved by technology

Wireless sensors generally have the following two problems: 1) When the wireless sensor wakes up from sleep, it takes a certain amount of time to re-network, establish a connection, and consume power; 2) In some strong electromagnetic interference or strong shielding environments, the wireless connection It is more difficult, and the reliability of data transmission is poor. At this time, the sensor will consume more power to retransmit. Failure to retransmit will result in data loss.

The disadvantage of wired sensors lies in the transmission distance and reliability of communication. The transmission distance of electrical signals is short, and in some strong electromagnetic interference environments, communication will become unreliable and the communication distance will also be shortened.
