Problems solved by technology

Since the external system interface in the server establishes a channel connection with the external system only when the server is the main server, after the server performs master / standby switchover, the external system interface in the new master server needs to re-establish a channel connection with the external system. may result in the loss of collected data
In addition, these automated monitoring systems generally establish channel connections with multiple external systems. When the channel connection between the primary server and external system A fails, and the channel connection between the standby server and external system B also fails, no matter how the servers are switched back to Inability to fully capture data from all external systems

Embodiment 1

[0037] This embodiment describes a redundant method, such as figure 1 As shown, the method includes:

[0038] Step 11, the first channel redundancy management module located in the first server establishes a channel with the external system through the external system interface in the server;

[0039] Step 12, judging that the channel established with the external system is the main channel, then using the main channel to collect data of the external system;

[0040] Step 13, judging that the channel established with the external system is a backup channel, then maintaining the connection of the backup channel.

[0041] In order to prevent data loss caused by re-establishing the connection between the external system interface and the external system during redundancy switchover, the external system interfaces on the two servers establish channel connections with the external system at the same time. A group of channels (including active channels and backup channels) constit...

Embodiment 2

[0062] This embodiment describes a redundancy management device that implements the method in Embodiment 1 above. The description in Embodiment 1 is also applicable to this embodiment. The redundancy management device is located at the first server, such as image 3 As shown, the device includes: a connection establishment unit 31, a data collection unit 32 and a connection maintenance unit 33, wherein:

[0063] The connection establishment unit 31 is configured to establish a channel with the external system through the external system interface in the first server;

[0064] The data collection unit 32 is configured to use the main channel to collect data of the external system when the channel established by the connection establishment unit and the external system is the main channel;

[0065] The connection maintaining unit 33 is configured to maintain the connection of the backup channel when the channel established by the connection establishing unit and the external sys...

Abstract

The invention discloses a redundancy method, a redundancy management apparatus, a server and a computer readable storage medium. The data loss or collection incompleteness caused in server switching is avoided. The redundancy method comprises the steps that a first channel redundancy management module located in a first server establishes a channel with an external system through an external system interface in the server, and if the channel established with the external system is judged to be a main channel, data of the external system is collected by utilizing the main channel; and if the channel established with the external system is judged to be a standby channel, connection of the standby channel is kept. The problem of influence of channel faults on connection of other channels is solved; the structure of the external system interface in the system becomes simple and easy to understand; and the maintainability, expandability and reusability of the system are improved.

Description

technical field [0001] The invention relates to rail transit automation technology, in particular to a redundancy method, a redundancy management device, a server and a computer-readable storage medium. Background technique [0002] In the field of rail transit, there are Integrated Supervisory and Control System (ISCS for short), Power Supervisory Control And Data Acquisitionsystem (PSCADA), Environment and Equipment Monitoring System (Building Automatic System, BAS), Train Automatic Monitoring System (Automatic Train Supervision, ATS) and other very important automation systems. They have a common feature, they all need to connect to some external systems, and monitor and control the real-time status of the equipment in these external systems, so the timeliness of data is highly required. These automation systems are distributed structures, composed of monitoring workstations and servers. The server is the core of the whole system, and the business processing service is ...
