Gateway power supply circuit, gateway integration device and gateway power supply method for elevator

Abstract

The embodiment of the invention provides a gateway power supply circuit of an elevator, a gateway integration device and a gateway power supply method. The gateway power supply circuit comprises a main control board power supply circuit, a current-limiting charging circuit, a switching circuit, a gateway and an energy storage capacitor, wherein the main control board power supply circuit is connected with the energy storage capacitor through the current-limiting charging circuit and the switching circuit, and the switching circuit is used for switching the main control board power supply circuit to charge the energy storage capacitor through the current-limiting charging circuit or directly charge the energy storage capacitor; and the energy storage capacitor is connected with the gatewayand supplies power to the gateway through a discharging process. According to the gateway power supply circuit, through a simple circuit design, when the elevator is powered off, enough current is provided for the gateway to send the power-off early warning information.

Description

Technical field[0001]The present invention relates to the field of elevator control technology, and more particularly to a gateway power supply circuit, a gateway integrated device, and a gateway power supply method for an elevator.Background technique[0002]Elevators include car elevators and step escalators, automatic sidewalks, and more. In the field of elevator control, a large number of elevator installation Internet of elevators have been used to monitor the purpose of monitoring and rescue. The Internet of Things has become a trend in the field of elevator.[0003]However, there are many kinds of electrical products in the field of elevator, the best way is not to move the original equipment, add an additional network gateway to achieve relevant functions. However, there is a very painful point of the electricity and energy storage of the plug-in gateway. Since the gateway transmits the signal, a very large instantaneous current is required, directly from the main control board,...
