Examples
The technical scheme provided by the invention is mainly used for energy-saving maintenance of the intelligent conference room. The intelligent conference room management system has the advantages that the indoor equipment operation state is dynamically adjusted through a series of modes such as equipment linkage rule configuration, automatic and manual operation mode switching, visual dynamic display and the like, and through cascade control and rule strategies, the problem of energy consumption waste in intelligent conference room management is solved to a certain extent, and the intelligent conference room management system is more energy-saving and more environment-friendly.
The mainstream intelligent conference room management is embodied in the intellectualization of the conference process, but the problems of environmental protection and the like are not considered, and some negative factors (poor human body feeling and the like caused by room temperature) which influence the states of participants in the conference process do not take countermeasures. Problems of manpower and energy waste often occur, such as:
1) intelligent conference rooms require special conference room administrators to maintain their on-off.
2) After the meeting room is finished, the meeting room is free of people, but the central air conditioner, the lamp and the large screen are still on, and if a manager of the meeting room is not in the meeting room, energy consumption is wasted for a long time;
3) the air conditioning temperature of the conference room is adjusted to be low or high, which causes discomfort to the participants. After manual adjustment, the indoor temperature can reach the comfortable degree of a human body within a period of time, so that the state of the participants cannot be adjusted, and the meeting efficiency is influenced. And too low or too high a temperature can result in a significant waste of energy usage.
4) Some meeting rooms with fresh air systems can always open the fresh air systems, and the fresh air systems can cause great energy waste when the fresh air systems are continuously opened when the concentration of carbon dioxide is relatively low.
The technical scheme of the invention can establish a set of energy-saving control method from the following aspects:
1) the intelligent air conditioner is additionally provided with an infrared camera (personnel counting function), an indoor and outdoor temperature sensor, an air quality sensor, an intelligent adjusting switch, an intelligent adjusting panel and an equipment communication strategy formed through linkage acquisition.
2) The temperature of different areas of the conference room is intelligently adjusted.
3) The fresh air quantity is increased and decreased through CO2 and automatic start and stop of particulate matter concentration.
4) The energy utilization strategy, automatic and manual switching and strategy abnormity alarm prompt are configured, and an automatic control closed-loop system is formed from the execution to the end of the conference.
5) A visual configuration management tool is provided, and remote configuration and control can be realized.
