Problems solved by technology

However, as the scale of the system continues to expand, the number of tasks that the main server needs to handle continues to increase, the processing pressure becomes greater, and failures are more likely to occur. As a result, the number of switching between the main server and the standby server increases, resulting in a decrease in system stability. Areas of Reliability Requirements

Embodiment 1

[0059] Take the application scenario where the operator station requests the control station to report data periodically as an example for illustration. The specific process is as follows: figure 2 Shown:

[0060] Step 201: The server group obtains periodic data upload management information from the RT server through a pre-configured RT server interface. The management information includes the length of the periodic table and the detailed information of the periodic report data.

[0061] The operator station interface can realize the function of reading / writing data directly from the operator. In this embodiment, the function realized by the operator station is the function of reading data, and the following parameters must be configured for the server group to realize the reading function:

[0062] parameter name use Types of Description RequestBuf Request parameter enter Point, station number, point name, item name, item value type, item length ReplyBuf Response parameters...

Embodiment 2

[0085] Take the application scenario where the operator station requests to modify the configuration information of the control station as an example, the specific process is as follows: image 3 Shown:

[0086] Step 301: The operator station sends a request message that carries management information of multiple control stations within the management range of the server group by the operator station.

[0087] Step 302: The server group sends the request message to multiple control stations within the management range.

[0088] In step 301 and step 302, the operator station sends the modification request to the server group, so as to modify the configuration information of multiple control stations within the management scope of the server group, which is similar to the configuration of one control station in the prior art. Compared with the information modification method, modifying multiple control station configuration information at a time improves the working efficiency of the s...

Embodiment 3

[0094] Take the application scenario of the operator station subscribing to the control station as an example. The specific process is as follows: Figure 4 Shown:

[0095] Step 401: The server group receives a subscription request from the operator station to subscribe data to the control station through the operator station interface.

[0096] Step 402: The server group determines whether the control station periodically sends the subscribed data; if so, execute step 403; otherwise, execute step 404.

[0097] Step 403: The server group obtains the subscribed data from the response message collected locally, and after step 403 is executed, step 406 is executed.

[0098] Step 404: The server group sends a request message including information about subscribing to the control station to the control station, and after step 404 is executed, step 405 is executed.

[0099] Step 405: The server group obtains the subscribed data from the response message sent by the control station, and after ...

Abstract

The invention discloses a data acquisition system and a device thereof, belonging to the technical field of communication. The invention solves the problem of poor system stability due to frequent switching of an active / standby server in a data acquisition system in the prior art. The data acquisition system comprises at least two data acquisition servers, wherein at least two data acquisition servers form at least two server groups which are both under operation condition and acquire data from a control station in the management scope. The technical scheme of the invention can be applied to the communication system with high requirement for reliability.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a data acquisition system and equipment thereof. Background technique [0002] In the existing large-scale data acquisition system, in order to ensure that the system can still work normally when some servers fail, the system adopts fault tolerance technology. The fault-tolerant technology can be implemented in the following manner: two servers with the same function are deployed in the system, the primary server and the standby server respectively. When it is detected that the main server cannot work normally, a main-standby switch is performed, the standby server is switched to a new main server, and the system continues to run. However, as the scale of the system continues to expand, the tasks that the primary server needs to handle continue to increase, the processing pressure becomes greater, and it is more prone to failures. As a result, the number of switching between the ...
