Elevator group control algorithm

Abstract

The invention relates to the technical field of elevator control systems, and discloses an elevator group control algorithm. The elevator group control algorithm comprises the following steps of firstly, setting three elevators to be normal; secondly, if only one up-down call-out signal or only one up-direction call-out signal or only one down-direction call-out signal exists in the three elevators, using the high elevator to respond to the down-direction call-out signal; thirdly, when the number of the up-down call-out signals in the three elevators is larger than or equal to 2, or the number of the up-direction call-out signals or the number of the down-direction call-out signals is larger than or equal to 2, comparing the total number of stopping times of the up-direction elevator with the total number of stopping times of the down-direction elevator; fourthly, setting the two elevators to operate normally and one elevator to break down, and carrying out algorithm verification; fifthly, setting one elevator to be normal and two elevators to break down, and carrying out algorithm verification; and sixthly, setting the three elevators to be faulty, and carrying out algorithm verification. According to the elevator group control algorithm provided by the invention, the situation of multiple times of same-floor overload entering or wrong elevator taking instruction inputting is solved through an elevator overload protection and wrong instruction elimination program block, the user requirements of high-rise buildings are better met, and the effect of improving the economic benefit is achieved.

Description

technical field [0001] The invention relates to the technical field of elevator control systems, in particular to an elevator group control control algorithm. Background technique [0002] Elevator control system refers to the elevator control system has gone through a process from simple to complex. The drag systems used for elevators mainly include: single and double-speed AC motor drive systems, AC motor stator voltage regulation and speed regulation drive systems, DC generator-motor thyristor excitation drive systems, thyristor direct power supply systems , VVVF variable frequency variable voltage speed regulation system. [0003] Among the elevator control systems currently on the market, timely responses are made according to the needs of passengers, and it can realize automatic elevator stop, door opening and closing, overweight reminder, floor indication, safety protection such as upper and lower limits, interlocking of landing doors, etc. And it can respond reason...

Problems solved by technology

[0003] Among the existing elevator control systems on the market, timely responses are made according to the needs of passengers, and automatic elevator stop, door opening and closing, overweight prompts, floor indications, and safety protections such as upper and lower limits and interlocking of landing doors can be realized. And it can respond reasonably according to different needs, but when the floor is high, the elevator is easy to be overloaded, and when there are many people entering the elevator, the user is easy to input wrong elevator instructions, resulting in low elevator operation efficiency
