Firstly, the main control modes for controlling the input parameters are classified as follows:
the above 8 kinds of control input parameters can be used as single input of the intelligent energy-saving system, and can also be used as input by combining multiple kinds at will.
Second, thing networking main control unit module

And a second module: and the scene database module is used for recording the configuration data of each scene of the scene.
And a third module: and the background service program module is responsible for executing an energy-saving scheme by three algorithm engines (a rule engine, a Fuzzy engine and an AI engine), namely controlling according to input parameters and combining scene configuration data.
A rule engine for setting control parameters by using the precise values of the parameters

the classroom is equipped with the following internet of things devices: the intelligent energy-saving system comprises a lighting lamp, an air conditioner, fresh air, an electric curtain, a fan, an electronic blackboard, a human body sensor, an environment light sensor and an environment sensor (a temperature sensor, a humidity sensor, a PM2.5 sensor, a PM10 sensor, a formaldehyde sensor, a TVOC sensor and a carbon dioxide sensor), wherein the human body sensor, the environment light sensor and the environment sensor are used as control input parameters of the intelligent energy-saving system; electrical equipment such as lighting lamps, air conditioners, fresh air, electric curtains, fans, electronic blackboards and the like are used as controlled equipment of the intelligent energy-saving system. The intelligent energy-saving system is deployed on a third-party cloud server (or an IDC machine room of a school).
School logistics personnel can log in the intelligent energy-saving system through a PC computer to configure an energy-saving scheme client, and set an energy-saving scheme policy as follows (meanwhile, the policy can be applied to a plurality of schools or classroom areas):
the weights of three variables (E: energy saving variable, P: user preference variable, W: work performance variable) of the AI engine reward function are set, Ww is 50%, We is 30%, and Wp is 20%.
Before class: human body induction and temperature sensor are combined. Keeping the light off, turning on the air conditioner 15 minutes in advance according to the ambient temperature, and turning on the light if people are detected to arrive at the classroom.
In class: human body sensor, environment light perception sensor, environment sensor and teaching scene's combination detects someone through human body sensor, and environment light perception sensor detects indoor illuminance and is bright on the right side, and wisdom economizer system can reduce the illuminance automatically, and environment light perception sensor detects indoor illuminance and is dark on the right side, and wisdom economizer system can be automatic with the illuminance increasement, and the prerequisite of reducing and increaseing is the illuminance that still guarantees national standard regulation's scene of giving lessons requirement. And the on-off and running states of the air conditioner, the fresh air and the fan are dynamically controlled according to environmental parameters such as temperature, PM2.5, carbon dioxide concentration and the like.
Rest in the break: human body induction, ambient light sensation and temperature sensors are combined, the electronic blackboard, fresh air and other equipment are closed, and if no one exists, the light, air conditioner and other equipment are also closed; if a person is detected, the light is adjusted to relatively low brightness according to the ambient light, and the air conditioner temperature is slightly higher (summer)/lower (winter) than the normal setting by 2 degrees according to the ambient temperature, so that the energy-saving purpose is achieved.
After school is placed: turning off all the devices, starting human body induction and ambient light induction, and turning on a lamp and adjusting the light to relatively low brightness if people are detected and the ambient light is dark; if no person is detected for 15 seconds, the light is turned off.
Human body sensor, temperature sensor and teaching scene's combination, for example under the scene of meeting room, detect someone through human body sensor and be in the meeting, temperature sensor detects indoor temperature on the high side, and wisdom economizer system can be automatic with the air conditioner temperature reduction and after the meeting, can the self-closing air conditioner when human body sensor detects nobody.
A combination of user preferences and instructional scenarios. After someone has controlled equipment state through wall switch or intelligent terminal, user's operation can cover wisdom economizer system automatically, for example the light of classroom lamp is shaded, and after the manual accent of student, wisdom economizer system can filter the light luminance under the current scene automatically, resumes until next classroom scene again. At the same time, the user experience (WpP) in the machine learning algorithm reward function is enhanced. In other words, if similar user operations occur multiple times in the teaching scenario, the algorithm model is more inclined to automatically adopt similar operations when detecting approximate input parameters after being repeatedly strengthened.
Human sensor, environment light perception sensor and teaching scene's combination, for example when summer sunshine is stronger, the peer of leaning on the window receives the influence of sunshine, detects someone through human sensor, and when environment light perception sensor detected indoor illuminance very strong, wisdom economizer system can self-closing (window) curtain.
Various combinations of input parameters and device controls are possible, and these are merely examples of preferred embodiments and are not all described in one row.
The background service program of the intelligent energy-saving system can dynamically execute the strategy of the energy-saving scheme to realize energy saving. With the increase of data volume and the accumulation of long-term use of the system, the system can autonomously learn an optimization model, so that more optimal configuration of energy conservation is achieved, and the system is more efficient and comfortable.
The above embodiments are only typical embodiments of the patent, and are also applicable to indoor energy saving in other industries (such as hotels, offices, shopping malls, etc.).
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
