Automatic watt hour meter

Abstract

The invention relates to an automatic watt-hour meter. The watt-hour meter is located in the elevator room. The watt-hour meter includes an electric energy measurement subsystem and a people counting subsystem in the elevator room. The electric energy measurement subsystem is used to detect and output the output of power frequency alternating current Electric energy, elevator room people counting subsystem is used to count the number of people passing by in the current elevator room where the watt-hour meter is located, and the number of people passing by each day is used as the data basis for elevator parking control. Through the present invention, while improving the measurement accuracy of the watt-hour meter, the equipment and space of the watt-hour meter can be fully utilized to flexibly formulate an elevator stop control strategy suitable for residents' travel.

Description

technical field [0001] The invention relates to the field of elevator management, in particular to an automatic watt-hour meter. Background technique [0002] In the prior art, there is no floor pedestrian counting device for counting the number of pedestrians carrying elevators on each floor, and such a floor pedestrian counting device needs to be placed in the elevator room of each floor, that is, placed on each floor In the public place waiting for the elevator, the equipment space provided in the elevator room on each floor is limited, and some necessary electronic equipment of the building has occupied some space in the elevator room. If the floor pedestrian counting equipment is a separate device The form design and placement of the building will occupy a large amount of public space, making the originally limited elevator room space more stretched, and bringing inconvenience to the travel and use of residents. [0003] At the same time, in the elevator room of each f...

[0002] In the prior art, there is no floor pedestrian counting device for counting the number of pedestrians carrying elevators on each floor, and such a floor pedestrian counting device needs to be placed in the elevator room of each floor, that is, placed on each floor In the public place waiting for the elevator, the equipment space provided in the elevator room on each floor is limited, and some necessary electronic equipment of the building has occupied some space in the elevator room. If the floor pedestrian counting equipment is a separate device The form design and placement of the building will occupy a large amount of public space, making the originally limited elevator room space even more stretched, and bringing inconvenience to the travel and use of residents

[0003] At the same time, in the elevator room of each floor, the watt-hour meter is a necessary electronic device for residents, but the measurement structure of the watt-hour meter in the prior art is too redundant, and the measurement of various parameters of the AC power supply line is not accurate enough. There is still room for optimization and improvement
