Monitoring method of elevator all-in-one machine, elevator all-in-one machine and monitoring system thereof

Abstract

The invention provides a monitoring method of an elevator all-in-one machine, the elevator all-in-one machine and a monitoring system thereof. The monitoring method of the elevator all-in-one machine comprises the steps that a communication module in the elevator all-in-one machine receives a monitoring request sent from remote monitoring equipment through a TTL interface; the monitoring request comprises a monitoring task and a monitoring period; a data collection module in the elevator all-in-one machine performs collection of monitoring data according to the monitoring task, and the communication module initiatively returns the monitoring data periodically to the remote monitoring equipment through the TTL interface according to the monitoring period. The traditional communication mode of a RS232 electrical level serial port adopted between a remote terminal (such as a computer) and an all-in-one machine is changed, the serial port communication of the TTL interface is used, various monitoring object data can be arranged in the remote monitoring equipment, which can not be limited by the rate of the transmission interface, the monitoring period is arranged in the monitoring task to trigger the elevator all-in-one machine to initiatively send collected monitoring data on time, and the monitoring precision and the monitoring data volume are improved.

Description

technical field [0001] The invention relates to the technical field of elevator monitoring, in particular to a monitoring method, device and system for an elevator integrated machine. Background technique [0002] The controller and variable frequency speed regulation driver used in the traditional elevator industry are all discrete, and the controller has a high failure rate. Terminal communication is used between the controller and the driver to achieve multi-speed operation, which leads to complex wiring and low control efficiency. , resulting in reduced stability and low operating efficiency of the elevator. Elevator integrated control technology refers to the integration of the elevator drive system and the elevator management system to achieve integration. With the promotion of the elevator integrated machine, due to its high integration, high reliability and low price, the proportion in the elevator market is also increasing. [0003] As the main tool for carrying p...

AI Technical Summary

Problems solved by technology

The elevator all-in-one machine is generally monitored by a hand-held operator. However, the hand-held operator can only view the data of the control part and the frequency converter separately, and the monitoring function is relatively limited; the monitoring accuracy of the hand-held operator is low, which makes it difficult to improve the accuracy of monitoring; The controller cannot record long-term data, so that the monitoring data is less; the operation of the hand-held operator is complicated, resulting in low real-time monitoring and monitoring efficiency

For example, when monitoring the instantaneous speed of an elevator, due to the limitation of display resolution, the speed value is not accurate enough, and related variables cannot be viewed at the same time, such as the relative timing relationship of the brake, resulting in unsatisfactory monitoring quality
