Monitoring and controlling system based on optical communication

Abstract

The invention relates to a monitoring and controlling system based on optical communication. The monitoring and controlling system comprises a sensor, a central control unit, an optical signal transmission unit and a terminal control unit, wherein the sensor is used for detecting measurand and transmitting corresponding information of the measurand to the central control unit; the central control unit is used for transmitting a control instruction to the optical signal transmission unit according to the information of the measurand; the optical signal transmission unit is used for transmitting out the control instruction in a form of an optical signal; the terminal control unit is used for receiving the optical signal and controlling terminal equipment according to the optical signal. According to the monitoring and controlling system based on optical communication disclosed by the invention, the detection control on the measurand is realized, so that a spectrum resource does not need to be applied for, no electromagnetic interferences exists, and the resource utilization efficiency can be improved. The monitoring and controlling system can be used for monitoring and controlling the measurand such as temperatures, humidity, illumination intensity, pH (Potential of Hydrogen) values, pressure, flows, liquid levels, differential pressure and ultrasonic waves.

Description

Technical field [0001] The invention relates to a monitoring and control system, in particular to a monitoring and control system based on optical communication. Background technique [0002] In warehouse management, manufacturing, breeding and nursing, meteorological observation, scientific research, and daily life, requirements for temperature, humidity, and light intensity are common. For example, in the management of archives, there are usually the following requirements: Archives (including film library) The temperature of the tape library should be controlled at 14~24℃, the daily change range of the warehouse with equipment should not exceed ±2℃; the relative humidity should be controlled at 45%~60%, and the daily change range of the warehouse with equipment should not exceed ±5% . With the rapid development of science and technology and the improvement of people's overall environmental awareness, people will also demand a balance between the comfort of the living environm...

Problems solved by technology

[0003] Although temperature regulators and humidity regulators are widely used in various fields, however, because the existing monitoring system cannot timely adjust the temperature and humidity regulators according to the environment, a lot of energy is wasted, especially in industrial and agricultural production. Waste of energy and waste of labor

For example, in our daily life, the air conditioner is still on after the temperature reaches the set temperature. Although the energy consumption is reduced, there is still wasted energy. The same problem exists in the humidifier.
