Ventilation control device and system for cinema

Abstract

The invention provides a ventilation control device and system for a cinema, and relates to the technical field of electrical equipment. The ventilation control device for the cinema comprises a central processor, ventilation devices and weight sensors arranged on seats respectively. When the ventilation control device for the cinema is in use, the weight sensors detect weight values generated when people sit on the seats, generate occupancy signals according to the weight values and send the occupancy signals to the central processor; the central process calculates the percent of the occupancy signals to the total number of the seats, compares the percent with a preset threshold range, controls the ventilation device at a first height position to be switched on when the percent is largerthan the upper limit of the threshold range, controls the ventilation device at a second height position to be switched on when the percent is within the threshold range, and controls the ventilationdevice at a third height position to be switched on when the percent is smaller than the lower limit of the threshold range. In this way, the purpose of switching on different ventilation devices according to different occupancy rates is achieved, and the ventilation control device for the cinema is convenient to use and saves energy.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a ventilation control device and system for theaters. Background technique [0002] With the development of science and technology and the improvement of people's living standards, various leisure activities are gradually enriched. In their spare time, people can plant flowers and raise fish, do sports, play video games, watch movies and so on. Among them, especially the rapid development of film-related technologies in recent years, people can enjoy various forms of movies under 3D, 4D, IMAX, water curtain, and dome scenes, thereby meeting people's appreciation needs. [0003] However, movies under the above-mentioned 3D, 4D, IMAX, water curtain, and dome scenes are usually played in movie theaters. The reason is that the realization of the above-mentioned special movie needs to be realized by means of many other devices (for example, water sprayer, shaking instru...

AI Technical Summary

Problems solved by technology

Although the construction of movie theaters has also increased in recent years, due to the relationship between movie release schedules and people's working hours, the attendance rate of movie theaters is very unstable

Sometimes the movie theaters are full during the release of a movie with a good reputation; sometimes the attendance rate is very low during the release of some movies

Regardless of the attendance rate, the same lighting, ventilation and other equipment will be used in the cinema hall of the cinema, which will not only cause a great waste of resources when the attendance rate is insufficient; audiovisual interference

[0004] To sum up, at present, there is no effective solution to the problem that cinemas cannot adjust the size of ventilation according to the actual occupancy rate
