Abstract

The invention discloses an elevator-waiting people recognizing device based on an infrared sensor and an elevator scheduling method based on people recognition, relates to the technical field of elevator control, and solves the problems of difficult industrial application, high economic cost and poor feasibility of the existing elevator-waiting people recognizing device, and low operation efficiency and high energy consumption of the existing elevator scheduling method. Human body detecting units of the device are used for detecting elevator-waiting people by an infrared sensing principle, and a detection result is sent to an elevator group control scheduling module through a data acquiring end microprocessor, a controller LAN (local area network) bus and a control end microprocessor. The elevator scheduling method comprises the steps that whether people stand at an elevator entrance is detected by the human body detecting units, the detection results of all the human body detecting units positioned on the same floor are analyzed by the data acquiring end microprocessor, a people quantity level signal of the floor is acquired and sent to the elevator group control scheduling module, and an optimum elevator scheduling scheme is output by the elevator group control scheduling module to schedule elevators. The device and the method disclosed by the invention are suitable for the elevator field.

Description

technical field [0001] The invention relates to the technical field of elevator control. Background technique [0002] Elevator group control system refers to a system in which three or more elevators form a whole for unified dispatching. Although the group control system greatly improves the efficiency and saves a lot of energy consumption, due to the lack of data on the number of people waiting for the elevator, the elevator group control host can only obtain the elevator service requirements of each floor according to the call signal. The elevator group control system has dynamic characteristics such as multi-objective, non-linearity and uncertainty. The traditional elevator group control technology has low operating efficiency and is prone to the phenomenon of elevators getting together, causing customers to take a long time and wait for a long time. Excessive start and stop times will result in energy waste, reduced elevator efficiency and reduced elevator service life...
