Safe elevator open-loop control machine

Abstract

The invention discloses a safe elevator open-loop control machine. The safe elevator open-loop control machine comprises an elevator driving motor, an elevator frequency converter, an elevator controller, an emergency power supply system and a fire-fighting monitoring system, wherein the elevator frequency converter is electrically connected with the elevator driving motor; a signal output end ofthe elevator controller is connected with a signal input end of the elevator frequency converter; a signal output end of the fire-fighting monitoring system is connected with a signal input end of theelevator controller; the fire-fighting monitoring system comprises a temperature sensor, a smoke sensor and an air quality monitor; the emergency power supply system comprises a power switch contactor and an emergency power supply; the emergency power supply is electrically connected with the power switch contactor; and a signal output end of the power switch contactor is connected with a signalinput end of the elevator frequency converter.

Description

Technical field [0001] The invention relates to an elevator control integrated machine, in particular to a safety elevator open loop control machine. Background technique [0002] With the increasing number of high-rise buildings in modern cities and the increasing utilization of space, people are increasingly dependent on elevators in high-rise buildings. [0003] However, because the current elevator control system is unscientific and unreasonable to control the elevator, the elevator control system and the drive system are basically separated, mainly based on the arrival instructions of each floor in the elevator and the upward or downward instructions of each floor. Carrying out simple logic calculations, there is no actual load data of the elevator in the elevator control system. The more people who need to take the elevator, the lower the working efficiency of the elevator, and it is difficult to meet people's needs, and the elevator will suddenly get stuck when the power fai...

Problems solved by technology

[0003] However, due to the unscientific and unreasonable control of the elevator by the current elevator control system, and because the elevator control system and the drive system are basically separated, it is mainly based on the arrival instructions of each floor in the elevator and the uplink or downlink instructions of each floor. Carrying out simple logic calculations, the elevator control system does not have the actual load data of the elevator. The more people need to take the elevator, the lower the efficiency of the elevator, which is difficult to meet people's needs, and the elevator will suddenly get stuck when the power is off. As a result, people stay in the elevator for a long time, causing suffocation and life-threatening
