Embodiment Construction

[0011] see figure 1 , an energy-saving elevator shown in the figure includes an elevator car and an elevator car driving system, the elevator car driving system includes an MCU control unit 100 and a frequency converter 200, and it also includes a human body arranged inside the elevator car The detection sensor 300 and the elevator car level detection sensor 400 arranged on the elevator car and the elevator leveling switch state detection module 500 arranged in the elevator car drive system.

[0012] The human body detection sensor 300 is used to detect whether there is a passenger in the elevator car. If there is a passenger in the elevator car, the human body detection sensor 200 sends the first elevator in running state signal to the MCU control unit 100. If there is no passenger in the elevator car, then the human body detection sensor 200 sends The first elevator is in an idle state signal to the MCU control unit 100 .

[0013] The elevator car level detection sensor 400...

Abstract

The invention discloses an energy-saving elevator. An elevator car and an elevator car drive system are included. The elevator car drive system comprises an MCU control unit and a frequency converter.The energy-saving elevator further comprises a human body detection sensor arranged in the elevator car and an elevator car horizontal height detection sensor arranged on the elevator car. The MCU interior control unit is in control connection with a lighting contactor and a fan contactor in the elevator car for connecting or disconnecting of electric power transmitting from a public power grid to lighting equipment and fan equipment in the elevator car. A contactor at the front end of the frequency converter is connected with the lighting contactor and the fan contactor in the elevator car and used for connecting or disconnecting electric power transmitting from the public power grid to the frequency converter. The contactor at the front end of the frequency converter is set to be conducted when the lighting contactor and the fan contactor in the elevator car are conducted at the same time, and the contactor at the front end of the frequency converter is set to be disconnected when the lighting contactor and the fan contactor in the elevator car are disconnected at the same time. The energy-saving elevator is good in energy saving effect.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an energy-saving elevator. Background technique [0002] With the increase of urbanization rate and economic development, there are more and more high-rise buildings. As an important means of transportation in buildings, elevators have been widely used in people's lives. It works around the clock to send users to their designated floors. The frequency of user use varies greatly and is uncertain at different time periods. Elevators consume a lot of electricity and are one of the largest energy-consuming equipment in high-rise buildings. According to the estimate of China Elevator Association, the average power consumption of each elevator in my country is about 40kWh per day, accounting for about 5% of the energy consumption of the entire building. When users use it, lighting and ventilation in the elevator car are essential. With the development of the economy, human beings'...
