Detailed Description
The embodiment of the application provides a method and a system for realizing the alarm service of the industrial system, and solves the technical problems that the industrial control system is easy to attack, the alarm service is difficult and the like.
The technical scheme in the embodiment of the application has the following general idea: the alarm data of the IO point in the industrial control system is provided to the client by the server, so that remote alarm at the client is realized, and the safety and the real-time performance of the industrial system are effectively guaranteed; and the request of the alarm data is in a paging request mode, namely when the client requests the alarm data from the server every time, the number of the alarms to be acquired needs to be transmitted and the alarm data of the current page needs to be acquired, but when the server returns the alarm data, only the first page of alarm data is returned, and the rest data is returned according to whether the client turns pages or not, so that the transmission quantity of the returned data every time is reduced, and the smooth transmission is ensured.
Example one
The embodiment provides a method for realizing industrial system alarm service, which comprises the following steps:
as shown in fig. 1, the real-time alarm data processing flow is as follows: the client sends a request for acquiring real-time alarm data, and the server responds to the request after receiving the request, namely acquiring the real-time alarm data of an IO point in the industrial control system from the database according to the input parameters and returning the real-time alarm data to the called client;
as shown in fig. 2, the historical alarm data processing flow is as follows: after a client provides a historical alarm condition setting interface to receive current query condition information set by a user, namely after the current query condition is set by the user, clicking 'determination', submitting the current query condition information to a server, judging the condition validity by the server, sending a current query condition information object to a historical alarm list in an EventBus Post mode after the judgment is passed, clearing current historical alarm cache data by the historical alarm list, and requesting a historical alarm record under the current query condition from the server; and the server side acquires historical alarm data of IO points in the industrial control system from the database according to the received request, returns the historical alarm data to the called client side, and fills the historical alarm data into the historical alarm list by the client side for display.
The data volume of the alarm is possibly larger, so that paging operation needs to be carried out on the alarm information, and the client requests the server for real-time alarm data or historical alarm data every time, and simultaneously transmits the number of alarms to be acquired, paging parameters and the current data of the page to be acquired.
The returned data may be in a fixed format, such as sequentially including: sequence number \ alarm time \ alarm IO point \ alarm parameter.
In the historical alarm data processing flow, when the historical alarm list requests the historical alarm records under the current query condition from the server, only the historical alarm record of the first page is requested; when the historical alarm list of the client is turned, searching whether historical alarm data of the page exists in a cache or not, if so, directly reading and displaying the historical alarm data, and not sending a historical alarm data request to a server; otherwise, requesting the historical alarm data of the page from the server, and caching the historical alarm data of the page after the request is returned. Therefore, the data volume returned by the server side every time can be greatly reduced, and the real-time performance of the data can be ensured.
As shown in fig. 3, when the client enters the history alarm list interface, a history alarm data request is performed by default, the time interval of the request is 1 hour before the current time, similarly, when the server receives the request of the client, the server still returns the history alarm information of the first page in the time interval 1 hour before the current time to the client, and meanwhile, the history alarm list interface automatically checks whether the current page has the alarm information of the time interval, if yes, the history alarm list interface displays the current page, and if not, the history alarm list interface does not display the current page.
As shown in fig. 4, the historical alarm data is turned by using buttons "previous page", "next page", and clicking a page number to input a page number, when the client turns a page, it is first determined whether the historical alarm data of the target page exists, if so, the historical alarm data of the target page is requested from the server, and if not, the process is ended.
As shown in fig. 5, the current query condition information refers to a historical alarm time period, and the condition validity judgment refers to judging whether the historical alarm time period set by the user is appropriate, that is, when the client enters the historical alarm list interface, the client enters the historical alarm condition setting interface, and when the historical alarm time period queried by the user is set, the client judges whether the set time period is appropriate. If the time interval is changed and the changed time interval is proper, the historical alarm data of the first page in the changed time interval acquired by the server are returned to the historical alarm list interface.

as shown in fig. 2, in the historical alarm data processing flow, after providing a historical alarm condition setting interface by the client to receive current query condition information set by a user, the client performs condition validity judgment, and after the judgment is passed, sends a current query condition information object to a historical alarm list in an EventBus Post manner, and clears current historical alarm cache data by the historical alarm list and requests the server for a historical alarm record under the current query condition; and the server side acquires historical alarm data of IO points in the industrial control system from a database according to the received request, returns the historical alarm data to the called client side, and fills the historical alarm data into the historical alarm list by the client side for display.
The data volume of the alarm is possibly larger, so that paging operation needs to be carried out on the alarm information, and the client requests the server for real-time alarm data or historical alarm data every time, and simultaneously transmits the number of alarms to be acquired, paging parameters and the current data of the page to be acquired.
The returned data may be in a fixed format, such as sequentially including: sequence number \ alarm time \ alarm IO point \ alarm parameter.
In the historical alarm data processing flow, when the historical alarm list requests the historical alarm records under the current query condition from the server, only the historical alarm record of the first page is requested; when the historical alarm list of the client is turned, searching whether historical alarm data of the page exists in a cache or not, if so, directly reading and displaying the historical alarm data, and not sending a historical alarm data request to a server; otherwise, requesting the historical alarm data of the page from the server, and caching the historical alarm data of the page after the request is returned. Therefore, the data volume returned by the server side every time can be greatly reduced, and the real-time performance of the data can be ensured.
As shown in fig. 3, when the client enters the history alarm list interface, a history alarm data request is performed by default, the time interval of the request is 1 hour before the current time, similarly, when the server receives the request of the client, the server still returns the history alarm information of the first page in the time interval 1 hour before the current time to the client, and meanwhile, the history alarm list interface automatically checks whether the current page has the alarm information of the time interval, if yes, the history alarm list interface displays the current page, and if not, the history alarm list interface does not display the current page.
As shown in fig. 4, the historical alarm data is turned by using buttons "previous page", "next page", and clicking a page number to input a page number, when the client turns a page, it is first determined whether the historical alarm data of the target page exists, if so, the historical alarm data of the target page is requested from the server, and if not, the process is ended.
As shown in fig. 5, the current query condition information refers to a historical alarm time period, and the condition validity judgment refers to judging whether the historical alarm time period set by the user is appropriate, that is, when the client enters the historical alarm list interface, the client enters the historical alarm condition setting interface, and when the historical alarm time period queried by the user is set, the client judges whether the set time period is appropriate. If the time interval is changed and the changed time interval is proper, the historical alarm data of the first page in the changed time interval acquired by the server are returned to the historical alarm list interface.
