FIG. 2 is a schematic diagram of system connection of the system of embodiment 1.
Detailed Description
The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention. In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
Embodiment 1, referring to fig. 1, an efficient elevator operation control method includes:
and step S100, acquiring the load capacity of the elevator car.
And S200, when the load capacity is larger than or equal to the load capacity threshold value, acquiring an outdoor temperature value of the building where the elevator is located.
And step S300, shooting a temperature distribution diagram in the elevator car.
And S400, calculating the proportion of the area of the region with the temperature being more than or equal to the threshold temperature in the temperature distribution diagram to the area of the whole temperature distribution diagram to obtain a proportion value.
The threshold temperature satisfies a temperature mathematical model, which is:
where T is represented as a threshold temperature and T is represented as an outdoor temperature value.
And S500, judging whether the proportional value is more than or equal to 80%.
And step S600, when the proportional value is more than or equal to 80%, the elevator car does not respond to the request signal on the floor.
Wherein the load threshold is equal to 85% of the maximum load of the elevator car.
Because the load capacity of the elevator car reflects the congestion degree of the elevator car, the load capacity of the elevator car is measured and compared with a load capacity threshold value, and when the load capacity is larger than or equal to the load capacity threshold value, the situation that the congestion degree exists in the elevator car is indicated. However, since the passenger sizes are different, the degree of congestion of the elevator car cannot be accurately known even when the load capacity is obtained, and therefore, it is necessary to take a picture of the temperature profile in the elevator car and further determine the degree of congestion in the elevator car from the temperature profile.
Because the ambient temperature in the elevator car is different from the outdoor temperature value of the building where the elevator is located to a certain extent, the outdoor temperature value of the building where the elevator is located needs to be obtained, the outdoor temperature value is used as a reference factor, and since a human body can change according to the outdoor temperature value, when the proportion of the area with the temperature being greater than or equal to the threshold temperature in the temperature distribution diagram occupying the whole area of the temperature distribution diagram needs to be considered. When the outdoor temperature value is lower, people often wear more clothes, and due to heat insulation of the clothes, when the elevator is crowded, the temperature value in the elevator car is not very high, so that the threshold temperature needs to be reduced, and through testing, when the outdoor temperature value is less than or equal to 15 ℃, the threshold temperature is most suitable for being 20 ℃. When the outdoor temperature value is high, people often wear fewer clothes, therefore, when the elevator is crowded, the temperature value in the elevator car is high, therefore, the threshold temperature needs to be increased, through testing, when the outdoor temperature value is between 15 ℃ and 30 ℃, the temperature threshold is selected to be most suitable at 25 ℃, and when the outdoor temperature value is above 30 ℃, the temperature threshold is selected to be most suitable at 28 ℃.
The proportion of the area of the region with the temperature being larger than or equal to the threshold temperature in the temperature distribution diagram occupying the area of the whole temperature distribution diagram is calculated to obtain a proportion value, the crowdedness in the elevator car can be reflected through the proportion value, whether the proportion value is larger than or equal to 80% is judged, when the proportion value is larger than or equal to 80%, the situation that the elevator car is crowded enough is indicated, at the moment, the elevator car is not suitable for responding to a request signal on a floor, the elevator car only responds to the request signal of the existing passenger in the elevator car requesting to stop the floor, and therefore the situation that the passenger can not stop on the floor any more is avoided.
