Intelligent electric energy meter for detecting elevator door and window states

Abstract

The invention relates to an intelligent electric energy meter for detecting elevator door and window states. The meter comprises electric energy detection equipment, elevator door and window state detection equipment and main control equipment, the electric energy detection equipment is used for detecting and outputting electric energy output by a three-phase electric power circuit, the elevator door and window state detection equipment is used for detecting the elevator door and window opening and closing states, and the main control equipment is connected with the electric energy detection equipment and the elevator door and window state detection equipment respectively. According to the intelligent electric energy meter for detecting the elevator door and window states, the staircase door and window opening and closing states can be detected by the electric energy meter, and accordingly the intelligent degree of the electric energy meter is improved.

Description

[0001] This invention is a divisional application of a patent with the application number 2016101824703, the application date is March 28, 2016, and the invention name is "Intelligent energy meter for detecting the state of doors and windows in elevator rooms". technical field [0002] The invention relates to the field of electric energy meters, in particular to an intelligent electric energy meter for detecting the state of doors and windows in elevator rooms. Background technique [0003] Elevator rooms, which are widely used in industrial and civil buildings, are built because of the actual needs of life, as a hub connecting up and down traffic. Most of the places where elevators are needed have elevator rooms, which provide the residents on the floor with the space they need to wait for the elevator. But in a few cases, it will not be built. There are open stairwells, closed stairwells and smoke-proof stairwells in the elevator room. [0004] Although the residents in...

Problems solved by technology

[0004] Although the residents in the elevator room stay for a relatively short time, their safety and thermal insulation cannot be ignored. A key factor affecting their safety and thermal insulation is the opening and closing of the doors and windows in the elevator room. Therefore, it is necessary to build in the elevator room. A set of door and window opening and closing state detection equipment, in order to notify the remote property management center to send an alarm in time when it detects that the door and window opening and closing state is not suitable, so as to remind the remote property management center to immediately arrange personnel to go to the corresponding elevator room Perform door and window opening and closing state change operation

[0005] However, the original public space in the elevator room is limited, and some necessary public facilities and residential facilities are installed in it, such as electric energy meters. If additional control equipment is placed in each elevator room, it will easily lead to equipment congestion in the elevator room It is unbearable, and it also causes inconvenience to the residents who come and go

At the same time, the existing electric energy meters in the elevator have redundant structures and poor performance, and there is still room for further optimization
