Problems solved by technology

On the 380V / 220V low-voltage power line, it is difficult to be used for signal transmission due to too many electronic devices and too much network noise.
Although there are technologies such as power line remote meter reading, the effect is not ideal, so it has not been widely promoted

Abstract

The invention relates to an air humidity sensor based on power line carrier communication, which is composed of a sensor (1), a carrier measurement port module (2) and a direct-current stabilized power supply (3), and signals of the carrier communication sensor can be transmitted through a 220V low-voltage power line. The problem that signals are difficult to transmit due to the fact that too muchelectronic equipment is carried on a 220V low-voltage power line to generate high noise is solved, signal lines do not need to be rearranged, and engineering construction cost is reduced to a large extent on the premise that reliability is guaranteed. The method is applied to an intelligent agricultural monitoring system, and the measured object is air humidity.

Description

technical field [0001] The invention is an air humidity sensor capable of transmitting signals through a 220V power line. The technical field relates to power line carrier communication and measuring instruments. Background technique [0002] The invention is mainly used for the measurement of air humidity in intelligent agricultural production, and can also be used in other fields. [0003] Smart agricultural monitoring will definitely involve the signal transmission method, which is related to the construction cost and reliability of the system. At present, the wired transmission method of arranging data lines and the wireless transmission method of Zigbee mode are widely used. The wireless transmission in Zigbee mode is a kind of wireless communication similar to a miniature base station. The construction cost of this wireless communication method is lower than the wired communication of data lines. However, the stability and reliability are difficult to compare with w...
