Embodiment Construction

[0026] This embodiment can be used for automatic control of a human body spray cooling system. In areas that need to be equipped with spray cooling, such as traffic police pavement duty boxes, outdoor operation sites, etc., this embodiment can be used for automatic control of the spray system.

[0027] This embodiment includes the following steps:

[0028] Step 1: Obtain the environmental parameters of the current large area. The large area is a city or an urban area in a city, and the environmental parameters include temperature parameters, air humidity, wind speed parameters and thermal radiation intensity, which are obtained from the current weather conditions through a network module connected to the Internet.

[0029] Step 2: Calculate and analyze the environmental parameters of the large area to obtain the thermal comfort index of the human body in the current large area, and then determine whether the thermal comfort index of the human body exceeds the preset threshold....

Abstract

The invention discloses a method for automatically controlling outdoor mist cooling based on outdoor environment human thermal sensation. The method comprises the following steps that firstly, environment parameters of a current large area are acquired; secondly, the environment parameters of the large area are calculated and analyzed, the human thermal comfort indexes of the current large area are obtained, then whether the human thermal comfort indexes exceed a preset threshold value or not is judged, if yes, the third step is executed, and otherwise operation returns to the first step; thirdly, a sensor is utilized for acquiring environment parameters of a current small area, the human thermal comfort indexes of the current small area are obtained through calculation and analysis, thenwhether the human thermal comfort indexes exceed a preset threshold value or not is judged, if yes, the fourth step is executed, and otherwise a spraying system is stopped and operation returns to thefirst step; and fourthly, the spraying system is started, and operation returns to the first step for cyclic execution. The method has the technical effects that under the principle of guaranteeing human comfort, the unnecessary running time of the spraying system can be reduced, and therefore the effect of saving energy is achieved.

Description

technical field [0001] The invention relates to a method for automatically controlling outdoor spray cooling based on human thermal sensation in outdoor environment. Background technique [0002] At present, there are still many physical and special tasks that need to be carried out outdoors, but in hot weather, the human body is easy to feel uncomfortable, and it will also lead to many problems such as decreased work efficiency. When it is inconvenient to install high power consumption devices such as air conditioners and electric fans, there are also examples of using spray devices to cool the human body. However, most of the existing outdoor spray cooling devices have the problems of ignoring the user experience and unreasonable energy consumption, that is, the spray start and stop cannot be adjusted and controlled according to the current environmental state, and must be manually turned on and off, and these two aspects are exactly This reflects its significant shortcom...
