Abstract: A monitoring system for controlling self-testing of a traction elevator includes a self-testing process module in communication with a three-phase AC back-up battery power supply. The self-testing process module includes a processor configured to initiate and control a series of steps for performing measurements of the three-phase AC back-up battery power supply, including measurements of the battery supply during a simulated emergency situation (“rescue/evacuation”). The processor is programmed to initiate testing on a defined schedule and transmit test results to a maintenance system (including remotely-located systems) on a routine basis. The monitoring system also includes a display unit providing visual information regarding the status of self-testing processes and their results and a communications unit for transmitting test results to a remote maintenance controller.

Abstract: An emergency power supply for a traction elevator system utilizes a microprocessor-based control arrangement with pulse-width modulator technology to create an efficient, cost-effective back-up power system for a traction elevator. The microprocessor-based control arrangement is used to sense a phase irregularity in the power supply. Upon sensing the phase irregularity, the microprocessor-based control arrangement disconnects the elevator system from the main power source and then generates a control signal to initiate the supply of back-up power. Once the elevator electrical system has been stabilized, the elevator control system will sense that recovery has occurred and will then provide an appropriate speed and direction command to the traction motor drive system.

The microprocessor-based control arrangement is used to sense a power loss, or any type of irregularity in the power supply.

Abstract: A back-up power system for a traction elevator includes a power sensing device to sense a power loss or irregularity of the normal control power. An inverter timing system is connected to the power loss sensing device. The inverter timing system receives a power sensing signal from the power sensing device. A back-up power generating system communicates with the inverter timing system and generates an output to provide back-up power to the elevator system.
