Elevator floor position learning system

Abstract

The invention discloses an elevator floor position learning system. According to the system, floor information is pre-stored in a control cabinet; after the control cabinet is powered on, a service floor position table is generated and stored according to the pre-stored floor information, and a generated instruction is sent to a function safety device; the generated instruction comprises the service floor position table; the function safety device stores the service floor position table in the generated instruction and feeds back a floor position synchronization completion instruction to the control cabinet; the control cabinet sends a check instruction to the function safety device after receiving the floor position synchronization completion instruction, and the check instruction comprises a check code; after receiving the check instruction, the function safety device checks a current service floor position table stored by the function safety device according to the check code, and if the check is passed, a check success instruction is sent to the control cabinet; if the control cabinet receives the check success instruction, an elevator is allowed to enter a high-speed automaticoperation mode. According to the elevator floor position learning system, the elevator floor position learning operation time can be saved, and the elevator floor position learning efficiency is improved.

Description

technical field [0001] The invention relates to elevator control technology, in particular to an elevator floor position learning system. Background technique [0002] When the elevator is equipped with an absolute position sensor, there is no concept of a shaft switch, but a functional safety device is added, which also needs to record the floor position, and only has the concept of a service floor, so its floor position table is called a service floor position table. The elevator control cabinet not only has a service floor location table, but also an elevator floor location table, which contains the location information of all floors (service floors and non-service floors). The functional safety device and the service floor position table of the control cabinet need to be checked each other. When the verification is passed, it means that the floor position has been learned and the elevator can run automatically at high speed. [0003] During commissioning, the floor posi...

Problems solved by technology

It is relatively difficult to accurately stop the elevator at the leveling position through the maintenance operation, which may require repeated operations many times to finally stop accurately. For elevator debugging, the debugging efficiency is not high
