Embodiment 2

[0059] This embodiment provides a platform door monitoring method based on a subscription-publishing model, such as figure 2 Shown, this method comprises steps:

[0060] Receive the first preset subject to be monitored issued by the monitored device inside the platform door and the subscribed first preset subject to be set;

[0061] Receive the second preset required monitoring topic issued by the external system of the platform door and the subscribed second preset required setting topic;

[0062] Receive the preset monitoring topic subscribed by the remote monitoring client and the preset management instruction topic issued;

[0063] Monitor and maintain the platform door according to the topics received and published and subscribed by the monitored equipment inside the platform door, the external system of the platform door, and the remote monitoring client respectively.

[0064] Specifically, the monitored equipment of the platform door, the external system of the platf...

Abstract

The invention provides a platform door monitoring system based on a subscription and release model and relates to the technical field of rail transit platform door monitoring. The method is used for solving the problems that at present, rail transit platform door monitoring interfaces all adopt customized communication protocols; the expansibility is poor, remote monitoring and maintenance are not supported; a platform door monitoring system of the system comprises a theme tree management module, a communication management module, a subscription management module, a Qos management module, an authority management module and a data recording module. The system is used for carrying out network transmission on data by taking data subscription and publishing as a communication model, monitored equipment in a platform door, an external system of the platform door and a remote monitoring client, and the data subscription and publishing adopt an MQTT protocol to subscribe and publish the data. The system is provided with the message middleware and a perfect hierarchical classification theme tree, has high expandability, and meets the expansion requirements of monitored equipment in the platform door, an external system of the platform door and a remote monitoring client.

Description

technical field [0001] The invention relates to the technical field of rail transit platform door monitoring, in particular to a platform door monitoring system and method based on a subscription-publishing model. Background technique [0002] In recent years, the platform doors of rail transit often break down, causing inconvenience to passengers and even affecting the safety of passengers. Therefore, the monitoring of platform doors is very important, and the monitoring of platform doors includes the monitoring of various monitoring components inside the platform doors. And including the monitoring of external systems. [0003] However, the existing typical rail transit platform door monitoring system, the internal monitoring network of the platform door system, and the communication interface between the platform door system and external systems all use customized communication protocols, which have poor scalability and do not support remote monitoring and maintenance. ...
