The invention is applied to an intelligent agricultural monitoring system, and the measurement objects are as follows: the intensity of the light.
Description
Technical Field
The invention relates to an illumination sensor capable of transmitting signals through a 220V power line. The technical field relates to a power line carrier communication and measuring instrument.
Background
The invention is mainly used for measuring illumination in intelligent agricultural production and can also be used in other fields.
The intelligent agricultural monitoring can involve a signal transmission method, and the method is related to the construction cost and the reliability of the system. At present, a wired transmission method for arranging data lines and a wireless transmission method in a Zigbee mode are used more. The Zigbee mode of wireless transmission is similar to the wireless communication of a femtocell, and the construction cost of the wireless communication mode is lower than that of the wired communication of a data line. However, stability and reliability are difficult to compare with wired communication, and particularly, in case of a disaster weather, the stability and reliability are often affected.
Power line carrier communication is a conventional technology. The application of the high-voltage power grid is mature on 35kV high-voltage and 10kV medium-voltage power grids. On a 380V/220V low-voltage power line, because the number of mounted electronic equipment is too large, network noise is too large, and the low-voltage power line is difficult to be used for signal transmission. Although the prior power line remote meter reading technology and the like are available, the effect is not ideal, so the method is not widely popularized.
The strong and weak current data conversion functional module has strong anti-interference capability. The method can better solve the problem of real-time signal transmission and reception in a high-noise environment internationally, and has stable signal transmission and no mutual interference. The invention saves the data line arrangement to a great extent. On the premise of ensuring reliability, the construction cost of the intelligent agricultural monitoring system is greatly reduced.
