Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as figure 1 As shown, the elevator energy-saving methods include:

[0031] S1. Monitor the input and output status of the I / O port of the elevator main control board;

[0032] The main control board of the elevator monitors the input and output status of the I / O port, and if there is no input or output at the input or output port within a preset time, step S2 is executed. The preset time may be 10-20 minutes, which is not limited in the present invention, and those skilled in the art may set the preset time according to actual conditions.

[0033] S2, outputting a sleep signal;

Abstract

The invention provides an elevator energy-saving method and system. The method for elevator energy saving includes: monitoring the input and output status of the I / O port of the elevator main control board; outputting a sleep signal when there is no input or output at the I / O port of the elevator main control board within a preset time. The elevator energy-saving system includes: an elevator main control board, a circuit path switch unit; the elevator main control board includes: a monitoring unit and a dormancy signal output unit; the monitoring unit: used to monitor the input and output state of the I / O port; The signal output unit is used to output a dormancy signal when there is no input or output at the I / O port within a preset time; the circuit path switch unit: disconnects the circuit path after receiving the dormancy signal. The elevator energy saving method and system provided by the present invention can realize energy saving in the idle state of the elevator.

Description

technical field [0001] The invention relates to the field of automation, in particular to an elevator energy-saving method and system. Background technique [0002] With the development of the city, there are more and more high-rise buildings that need to use elevators. With the increase in the use of elevators, the energy consumption of elevators has also become a concern. In the survey and statistics of electricity consumption in hotels, office buildings and other buildings, it is found that the electricity consumption of elevators accounts for 17% to 25% of the total electricity consumption, second only to the electricity consumption of air conditioners, and higher than the electricity consumption of lighting and water supply. , becoming one of the largest energy consumers. Therefore, environmentally friendly and energy-saving elevators have become the development trend and common goal of the elevator industry. [0003] In the prior art, parallel connection, group cont...
