Intelligent elevator control system

Abstract

The invention discloses an intelligent elevator control system, which is used for detecting elevator failures and comprises an elevator master controller and an elevator safe circuit, wherein the elevator safe circuit comprises a safe switch unit and a gate lock switch unit connected in series; the elevator safe circuit also comprises a plurality of safety monitoring points which access to a plurality of serial communication circuit boards; each serial communication circuit board is also provided with a communication address which can be identified by the control system; the elevator safe circuit exchanges data with the elevator master controller by a serial communication way to send working statuses in real time. By adopting the way, the invention provides the intelligent elevator control system, thereby intellectualizing the failure detection of the elevator safe circuit, capable of quickly detecting failure points of the elevator, prolonging the failure-free running time of the elevator and improving the maintenance precision and the working efficiency of the elevator safe circuit.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an intelligent elevator control system, which can be applied to vertical running elevators and inclined running elevators. Background technique [0002] In recent years, the rapid growth of my country's economic construction has brought unprecedented opportunities for the elevator industry. With the rapid development of the industry, my country's elevator products have accounted for more than 50% of the world's share. Statistics from the Elevator Industry Association show that my country's elevator industry is developing rapidly. At present, the growth rate of elevator demand exceeds 15%, and the space is huge. The number of elevators registered in my country is growing at a rate of more than 20% per year. As early as a few years ago, my country has become the country with the largest number of elevators in the world. Currently, China is using The number of elevators has exceeded 1.6 mill...

Problems solved by technology

However, since there are many types of these switches that make up the elevator safety circuit, and the installation locations are distributed in the elevator machine room, the elevator shaft, and the bottom pit of the elevator shaft, this circuit design can only play the role of electrical safety protection for the elevator. When the circuit breaks down and the elevator stops protectively, this kind of circuit design cannot help to quickly find the fault point. It can only judge the safety circuit or door lock circuit fault generally through the safety contactor or door lock contactor, and cannot Very clear indication of which switch has failed

Therefore, finding elevator electrical faults is a very professional job, which requires maintenance personnel to have considerable professional training and work experience
