Elevator running performance real-time monitoring system

Abstract

The invention discloses an elevator running performance real-time monitoring system. The system comprises an elevator running controller and a host computer which are communicated with each other through a serial port by using the optimal baud rate, wherein the host computer transmits a monitoring variable address and a data request to the elevator running controller according to a monitoring option which is set by a user, receives an acquired packet which is transmitted back by the elevator running controller, unpacks and displays the unpacked packet on a human-computer interaction interface in the form of a curved line; and the elevator running controller acquires data in the address set by the host computer at regular time, stores the data in a buffer region, performs corresponding processing according to the condition of the acquired data stored in the buffer region after receiving the data request transmitted by the host computer, and packs and transmits the data which is acquired at the earliest stage in N periods to the host computer. The elevator running performance can be continuously monitored in real time without a special relay device, so the fault diagnosis and analysis efficiency is improved, the cost is reduced, the system is convenient to use, and the reliability of communication is improved.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to a system for real-time monitoring of elevator running performance. Background technique [0002] In the stage of elevator development or on-site installation and commissioning, when it is necessary to diagnose the cause due to poor elevator performance, it is necessary to continuously monitor the elevator’s operating performance in real time and display it in an intuitive way, so as to facilitate diagnosis and analysis of the cause. At present, the method adopted by the general-purpose frequency converter is to first collect the data identifying the elevator’s operating performance and store it in the memory of the frequency converter; when the data collection of the fixed-period number is completed, it is sent to the host computer through the serial port at one time; The host computer displays the collected data on the man-machine interface in the form of a curve. Although this ...
