Device for rescuing people in faulted elevator

Abstract

The invention provides a device for rescuing people in a faulted elevator, and aims to rescue passengers in the faulted elevator without the aid of professional elevator technicians. Moreover, the device is simple to operate, and the rescuing time is quite short. When the elevator fails or stops due to power failure and the passengers are trapped in the car of the elevator, related personnel onlyneed to operate an operator, then the device for rescuing people in the faulted elevator drives the elevator, and the passengers are rescued automatically. In the whole process from operation on the operator to escaping of the passengers, the device has the corresponding prompts, and thus, reminding and appeasing effects can be achieved.

Description

technical field

[0001] The invention relates to an elevator failure release device for releasing passengers trapped in the elevator car after an elevator failure or power failure. Background technique

[0002] For the current elevator failure, it is completely dependent on elevator professional and technical personnel to rescue passengers trapped in the elevator car. However, there are too many uncertainties in this process. For example: time delay caused by traffic, the ability level of elevator professional technicians, there is no elevator professional technician nearby to rescue, and passengers’ need for help cannot be effectively conveyed, etc. This greatly affects the rescue of passengers, and even serious consequences may occur. Contents of the invention

[0003] The purpose of the present invention is to make the passengers get out of trouble, without the need for elevator professional technicians to rescue them. Moreover, the operation is simple, and the escape...

Examples

Embodiment Construction

[0030] The manipulator of the release device is placed in the elevator car, and it is connected with the main controller through the accompanying cable. The manipulator includes a power switch, two buttons, a digital tube, and a buzzer;

[0031] Passengers in the elevator can realize the following functions by operating the two buttons of the manipulator: power on the manipulator, request to start, request to short circuit, and request to confirm. The manipulator has corresponding sound and digital display;

[0032] The power supply of the elevator driven by the release device is provided by the battery and the external alternating current;

[0033] The way for the release device to obtain the car door zone signal is to collect the original door zone sensor signal of the elevator.

[0034] The microprocessor of this release device adopts TMS320LF2407, which generates a three-phase voltage vector modulation signal to the motor drive circuit to drive the elevator traction moto...
