Problems solved by technology

[0002] Household elevators mainly refer to some privately installed vertical elevators for home use. Since home elevators are considered private elevators, generally home elevators are not guarded 24 hours a day. People cannot be detected in time, and due to privacy protection and low cost considerations for private areas, active personnel detection equipment (such as infrared cameras or surveillance cameras, etc.) is generally not installed in home elevators, which leads to the daily use of home elevator On the one hand, there are hidden dangers that people are trapped and cannot be discovered by the outside world in time
[0003] That is to say, there is a lack of a low-cost elevator personnel detection method suitable for home elevator scenarios in the prior art

Embodiment Construction

[0096] The embodiment of the present application provides an elevator personnel detection method and a related device, which can quickly determine whether there is a person in the elevator bridge car at low cost and is applicable to the scene of a home elevator.

[0097] It should be noted that the brake opening current in the embodiment of the present application refers to the current of the home elevator when the brake motor starts to operate after the bridge door is closed. The research shows that home elevators often have a small load, low running speed, and small operating current of the brake motor. Therefore, once there is a load change in the bridge compartment of the home elevator, it is responsible for providing the uplink power and downlink for the bridge compartment of the home elevator. The opening current of the power brake motor will change significantly. The embodiment of the present application mainly compares the current opening current of the opening current...

Abstract

The embodiment of the invention discloses an elevator personnel detection method and a related device. Whether people exist in an elevator car or not can be rapidly determined in a low-cost and home elevator scene. The elevator personnel detection method provided by the embodiment of the invention comprises the following steps of: recording a breaking current when a home elevator is in a no-load state; when the home elevator is closed and runs, obtaining a current breaking current of the home elevator; judging whether the current breaking current is within a preset range of the breaking current or not; if the current breaking current is within the preset range of the breaking current, determining that no person exists in the elevator car of the home elevator; and if the current breaking current is not within the preset range of the breaking current, determining that people exist in the elevator car of the home elevator.
