Electricity degree metering mechanism used for electric charge shareing for building elevator

Abstract

The invention discloses an electricity metering device and method for apportioning electricity charges for building elevators. The device includes a total electricity meter and a public electricity meter installed on the elevator power supply line, wherein the public electricity meter passes through a current transformer The contacts of the first relay and the second relay sense electricity from the elevator power supply line. The public watt-hour meter is installed after the elevator master watt-hour meter and before the power and lighting circuit breaker. The first relay, the second relay and the elevator control circuit The brake contactor or running contactor of the elevator is connected and controlled, and the counter is connected and controlled with the brake contactor or running contactor of the elevator control circuit. Through the electricity metering of the elevator in different working conditions by the device, considering the equal use of elevator times and public electricity charges by all building owners, combined with mathematical methods, a more scientific, reasonable and basically acceptable elevator electricity sharing fee can be obtained.

Description

technical field [0001] The invention belongs to a metering device for electricity consumption and a method for apportioning electricity charges, in particular to an electricity metering device and method for apportioning electricity charges for building elevators. Background technique [0002] In property management, whether the electricity fee for using elevators should be apportioned according to the height of the floor, and how to define the standard of apportionment according to the height of the floor has become a major problem in the real estate sales and property management industries. If there is no sufficient scientific basis for apportionment of electricity charges for elevator use according to the floor level, the apportionment will become the source of opinions of the owners, which will also affect the development of real estate sales and property management. Although there are currently some elevators that use electricity fee sharing methods, none of them can pe...

Problems solved by technology

If there is no sufficient scientific basis for apportionment of the electricity fee for elevator use according to the height of the floor, the apportionment will become the source of opinions of the owners, which will also affect the development of real estate sales and property management.

Although there are currently some elevators that use electricity fee sharing methods, none of them can perfectly solve the existing problems. For example, there are problems of "free riding" and "no one pays for the elevator standby electricity fee" when taking an elevator with an IC card, and some property companies The "one price for several floors" regional method of apportioning elevator electricity bills cannot win the trust of the public.
