Description

Technical Field

[0001] The present invention relates to the field of working face monitoring, and in particular to a method for processing a display monitoring system interface under a QT high-load scenario. Background Art

[0002] The energy industry is the lifeline of our country's industrial development, and the coal industry plays an important role in our country's economic construction and development. However, the safety production situation in my country's coal industry is not optimistic. Major casualties have been reported frequently in the news, and mining accidents have occurred frequently, causing casualties and losses that have brought serious adverse effects to society. The issue of coal mine safety production has received more and more attention from society and the country. All of these have put forward higher requirements for the monitoring system of coal mine safety production services.

[0003] According to the analysis of existing underground comprehensive mining monitoring systems in China, the main hosts of display devices on the comprehensive mining surface of coal mines are mostly computers with general performance; and there are more than a dozen devices to be connected, receiving about 3,000 data per second. The amount of data is too large, and the interface displays a lot of content. When all are refreshed, the equipment monitoring interface will be stuck, and there is also a delay in the real-time interface data, which cannot meet the requirements of implementing data display. Therefore, it is impossible to play the role of helping workers on the working surface to monitor data in real time from the software. Most of the time, it still depends on the experience of on-site operators to determine the status of the equipment.

[0004] In addition, since the equipment on the fully-mechanized mining surface of a coal mine must meet the safety regulations for fully-mechanized mining surfaces of coal mines, high-performance computers cannot be operated on fully-mechanized mining surfaces of coal mines because they do not meet the intrinsic safety and explosion-proof requirements for mines.

[0005] In general, it is imperative to provide a monitoring system that not only meets the intrinsic safety and explosion-proof requirements of mining, but also enables smooth operation of the monitoring interface.

[0006] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0007] The purpose of the present invention is to provide a method for displaying a monitoring system interface in a high-load scenario based on QT in view of the deficiencies in the prior art.

[0008] In order to achieve the above object, the first aspect of the present invention provides a method for processing the interface of a display monitoring system based on a QT high-load scenario, which is applied to an interface display module of a fully mechanized mining face monitoring system, comprising the following steps: Step 1, create a cache, and after starting each monitoring interface, register the interface pointers of all components in the monitoring interface into the cache; Step 2, monitor the screen image on each display in real time to determine the target monitoring interface; wherein N monitoring interfaces are displayed through M displays, and each display only displays one monitoring interface at a time; Step 3, searching for a corresponding interface pointer in the cache based on the target monitoring interface, and calling a corresponding component according to the interface pointer; Step 4: When the component is called, a timed refresh mechanism is executed to refresh the data.

[0009] Further, when the monitoring interface is switched on the screen of the display, an interface switching instruction is received, wherein the interface switching instruction includes target monitoring interface information; Based on the target monitoring interface information, searching for a corresponding interface pointer in the cache, and calling a corresponding component according to the interface pointer; The moment the component is called, a single data refresh mechanism is triggered to refresh the data.

[0010] Furthermore, after the component refresh mechanism is started, it is determined whether the data value of the data point corresponding to the component has changed. If it has changed, it is refreshed; if it has not changed, it is not refreshed.

[0011] Furthermore, for a monitoring interface that is not displayed on the display, when its associated data changes, the data is acquired and updated in real time and saved in the local cache data.

[0012] In order to achieve the above-mentioned object, the second aspect of the present invention provides a device for processing a display monitoring system interface in a QT high-load scenario, comprising: A registration module is used to create a cache and, after starting each monitoring interface, register the interface pointers of all components in the monitoring interface into the cache; The monitoring module is used to monitor the screen images on each display in real time and determine the target monitoring interface; wherein N monitoring interfaces are displayed through M displays, and each display only displays one monitoring interface at a time; A component calling module, used to search for a corresponding interface pointer in the cache based on a target monitoring interface, and call a corresponding component according to the interface pointer; The refresh module is used to execute the timed refresh mechanism to refresh data when the component is called.

[0013] In order to achieve the above-mentioned object, the third aspect of the present invention provides a fully mechanized mining face monitoring system based on a QT high-load scenario, comprising: an equipment proxy module, an mqtt data publishing module, a data display module, a business processing module and a data storage module; The equipment proxy module is used to connect to various fully mechanized mining equipment on the fully mechanized mining working surface; The MQTT data publishing module is used to publish the data received by the device proxy module for interface display by the data display module, for analysis and processing by the business processing module, and for storage by the data storage module; The data display module is used for real-time display of data and query display of historical data; The business processing module is used to perform analysis and docking after data reporting; Wherein, the data display module includes the interface display processing device described in the second aspect.

[0014] In order to achieve the above-mentioned objective, the fourth aspect of the present invention provides a computer-readable storage medium, wherein the storage medium stores at least one executable instruction, and the executable instruction enables a processor to execute the steps of the method proposed in the first aspect.

[0015] In order to achieve the above-mentioned purpose, the fifth aspect of the present invention provides a computer device, including a processor, a communication interface, a memory and a communication bus, wherein the processor, the communication interface and the memory communicate with each other through the communication bus; the memory is used to store computer programs; the processor is used to execute the steps of the method proposed in the first aspect when executing the program stored in the memory.

[0016] The present invention has outstanding substantial features and significant progress compared with the prior art. Specifically, the present invention creates a cache, and after starting each monitoring interface, registers the interface pointers of all components in the monitoring interface into the cache; and monitors the screen image on each display in real time to determine the target monitoring interface, and then searches for the corresponding interface pointer in the cache based on the target monitoring interface, calls the corresponding component according to the interface pointer, and executes a timed refresh mechanism to refresh the data during the component being called; the above scheme allows the monitoring interface to be refreshed only when it is displayed on the display, thereby reducing resource waste; further, the component is refreshed once the moment it is called, so that the data in the cache is refreshed to the interface, thereby reducing the problem of data display at the moment of refreshing; further, after calling the component, the timed refresh mechanism is executed, which can reduce the instantaneous resource occupation of the computer CPU; in terms of component refresh mode, the method of refreshing when the data changes and not refreshing when the data does not change can achieve no waste of computer resources and reasonable use of computer resources.

[0021] Traditional fully mechanized mining face monitoring system Figure 1 As shown, it includes an equipment proxy module, an mqtt data publishing module, a data display module, a business processing module and a data storage module; among them, the equipment proxy module is responsible for connecting to the data of each device on the comprehensive mining working face, and accessing the monitoring system with the protocol of each device; the mqtt data publishing module is responsible for publishing the data accessed by the equipment proxy module, for the data display module to display the interface, for the business processing module to analyze and process, and for the data storage module to store; the data display module is responsible for the real-time display of data and the query and display of historical data; the business processing module is responsible for the analysis and connection after the data is reported.

[0022] In practice, the monitoring screens on the fully mechanized mining face include the coal machine screen, the three-machine pump control screen, the support screen, the power supply screen, and the automatic proportioning screen, but most fully mechanized mining faces only have three monitors to display these data. This results in the corresponding interface being refreshed in real time when the monitoring screen of some equipment is not displayed, resulting in a serious waste of resources for refreshing, especially for computers with low performance, which will cause freezing and unsmoothness after the meeting.

[0023] The present invention optimizes the interface management processing method after plug-in loading, and proposes a QT-based real-time adaptive refresh method for the interface, so as to realize a monitoring interface with no lag when there is too much data and high real-time performance of the interface data.

[0024] The technical solution of the present invention is further described in detail below through specific implementation methods.

[0025] Example 1 This embodiment provides a method for processing the display monitoring system interface under a QT high-load scenario, which is applied to the interface display module of the fully mechanized mining face monitoring system. Figure 2 As shown, the following steps are included: Step 1, create a cache, and after starting each monitoring interface, register the interface pointers of all components in the monitoring interface to the cache; in the specific implementation, the monitoring interface includes at least a coal machine display interface, a three-machine pump control display interface, a bracket display interface, a power supply display interface and an automatic proportioning display interface.

[0026] It is understandable that each monitoring interface may include layout components, separator components, button components, table item views, table item components, container components, input components, display components, etc. When starting a component, the corresponding component in the interface is registered in the cache from the overall UI library, and a component pointer is obtained for later calling.

[0027] Step 2: Monitor the screen image on each display in real time and determine the target monitoring interface.

[0028] The N monitoring interfaces are displayed through M displays, each display displays only one monitoring interface at the same time, and M is less than or equal to N.

[0029] That is, the number of displays is smaller than the interface types. For example, the number of monitoring interfaces is 5, while the number of displays is 3; therefore, the interfaces need to be displayed in turn.

[0030] During specific use, the interface polling order and polling interval can be pre-set; the interface switching can also be realized by manually clicking the interface switching button.

[0031] Step 3: search for a corresponding interface pointer in the cache based on the target monitoring interface, and call a corresponding component according to the interface pointer.

[0032] Step 4: When the component is called, a timed refresh mechanism is executed during the component calling process to refresh the data.

[0033] The above solution allows the monitoring interface to be refreshed only when it is displayed on the monitor, thereby reducing resource waste.

[0034] Furthermore, for monitoring interfaces that are not displayed on the monitor, when their associated data changes, the data is obtained and updated in real time and saved in the local cache data, so that when the subsequent monitoring interface is displayed, the real-time data can be refreshed to the interface in time.

[0035] In specific implementation, a time is randomly selected as a refresh interval for scheduled refresh, and the refresh interval is generally small, usually less than 1 second.

[0036] Further, in one embodiment, in order to reduce the information display lag problem caused by the interface not being refreshed at the instant when the component is called and having to wait until the scheduled refresh time to refresh, when the monitor interface is switched on the screen of the display, an interface switching instruction is received, and the interface switching instruction includes target monitor interface information; Based on the target monitoring interface information, searching for a corresponding interface pointer in the cache, and calling a corresponding component according to the interface pointer; The moment the component is called, a single data refresh mechanism is triggered to refresh the data.

[0037] The above solution refreshes the data in the cache to the interface through an active refresh at the moment of interface refresh, thereby reducing data display problems at the moment of refresh.

[0038] Furthermore, since there are multiple components on each monitoring interface, in order to reduce the instantaneous resource occupation caused by the simultaneous refresh of multiple components, in one embodiment, when multiple components are called at the same time, they are refreshed in a preset order, thereby reducing the resource occupation easily caused by the simultaneous refresh and reducing the screen display jams.

[0039] Specifically, the preset order can be set by the user in advance according to the importance and preference of the data.

[0040] Furthermore, after the component refresh mechanism is started, it is determined whether the data value of the data point corresponding to the component has changed. If it has changed, it is refreshed; if it has not changed, it is not refreshed, thereby avoiding waste of computer resources and making rational use of computer resources.
