In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
As described in the background, with the development of the internet of things technology in recent years, thousands of video devices have been installed and put into use all over the country, and there is a demand for using online status data of the devices in both the field of industrial monitoring and big data statistics. In the prior art, the online status of the device is usually reflected by uploading heartbeat data and uploading event data.
Generally, the online status data uploaded by the video device is usually limited to the functional design of the device itself and the format definition of the communication protocol, and the diversity of the devices results in the diversity of the communication protocols, which increases the difficulty of directly using the online status data of the device. In the content of the device status data, the content is single and the format is fixed in the prior art, so that the effect and the form of reflecting the online status of the device are not comprehensive. And if the online state data of the devices such as heartbeat and online and offline events are uploaded from the device side at the same time, great pressure and challenges exist in the aspects of the use and processing performance of network traffic when a large amount of devices are loaded.
In view of the above, the present application provides a video device status calculation output method based on stream calculation. As shown in fig. 1, in one embodiment, the method includes:
step S110, acquiring a device end heartbeat data stream generated based on the device end heartbeat data, and acquiring a timing detection activation data stream generated based on the timing detection activation data of the device;
specifically, in this embodiment, the generating process of the device side heartbeat data stream includes:
receiving heartbeat data sent by each device at regular time and processing and converting the heartbeat data into device-side heartbeat data (which is easy to understand that the heartbeat data needs to be processed and converted by adapting to the communication protocol definition adopted by the actual device), wherein the device-side heartbeat data comprises device identification information (or device id information) and occurrence time information of the heartbeat data;
based on the common knowledge in the art, the data stream (data stream) is a group of ordered data sequences, and here, the heartbeat data of each device end are sequenced according to the occurrence time, so that the heartbeat data stream of the device end is generated.
In order to implement the stream calculation processing in the subsequent step, the participation of the timing detection activation data stream is also required, in this embodiment, the generation process of the timing detection activation data stream includes:
a server management end (located on a server side opposite to the equipment side) generates timing detection activation data at regular time according to equipment identification information in an access equipment list, wherein the timing detection activation data comprises equipment identification information (equipment id information) and data generation time information;
and similarly, sequencing the timing detection activation data according to the data generation time to generate a timing detection activation data stream.
It should be further noted that the execution subject of the method in this embodiment is a device state calculation processing service on the server side.
Continuing to return to fig. 1, after the device end heartbeat data stream and the timing detection activation data stream are obtained and then used as input data streams, performing step S120, performing aggregation operation calculation of preset logic according to the device end heartbeat data stream and the timing detection activation data stream, generating a device state data stream, and issuing the device state data stream to a device state message queue;
wherein, the aggregation operation calculation comprises: and analyzing the data in the data stream, and aiming at any equipment,
and in a heartbeat interval time period, if equipment end heartbeat data exist in the equipment, generating and outputting online state data of the equipment, and if the equipment only exists timing detection activation data, generating and outputting offline state data of the equipment.
It is readily understood that the above description of the calculation of the aggregation operation is directed to a specific device, and in practical implementation, the above process includes a process of grouping the device identification information in the data and sorting the data in the group in ascending order of time, so as to implement the above-described data calculation operation for any device based on the security isolation feature between the data in the flow calculation process.
According to the technical scheme, the method and the device have the performance advantage when massive equipment is processed in an online state based on the characteristics of high throughput, low time delay and safe isolation between data of flow calculation. In the implementation of the technical scheme, the state of the equipment is determined and output based on a specific flow calculation processing operator, wherein network uploading of online and offline event data is not involved, and the saving of network flow is facilitated. In addition, in the implementation of the method, the format of the input data stream is unified by adapting the communication protocol definitions of the online states of various devices, and the difficulty brought to the use of the online state data of the devices by the diversity of the communication protocol definitions of the devices is reduced.
To facilitate understanding of the technical solutions of the present application, the technical solutions of the present application will be described below with reference to another embodiment.
As shown in fig. 2, this embodiment, similar to the previous embodiment, also includes:
acquiring a device side heartbeat data stream generated based on device side heartbeat data and acquiring a timing detection activation data stream generated based on timing detection activation data of a device;
and performing aggregation operation calculation of preset logic according to the device end heartbeat data stream and the timing detection activation data stream, generating a device state data stream (corresponding to "aggregated device state data stream" in fig. 2) and issuing the device state data stream to a device state message queue (corresponding to "output to device state message queue" in fig. 2).
In order to flexibly adapt to various service scene needs and meet different requirements of users, in this embodiment, as shown in fig. 2, the method further includes:
filtering the device status data stream according to the online status data and the offline status data, and outputting the online status data stream and the offline status data stream respectively (corresponding to "separating the online status data stream" and "separating the offline status data stream" in fig. 2, respectively);
and correspondingly publish the online state data stream and the offline state data stream to an online state message queue and an offline state message queue (corresponding to "output to online state data message queue" and "output to offline state data message queue" in fig. 2, respectively).
Further, in this embodiment, in the process of processing the device status data stream, if the data type of the adjacent data in the stream of the same device is changed from the offline status data to the online status data, the online event data of the device is generated, and if the data type of the adjacent data in the stream of the same device is changed from the online status data to the offline status data, the offline event data of the device is generated;
an output device online status event data stream (corresponding to "generate online status event data stream" in fig. 2) is generated based on each online event data and each offline event data, and posted to a device online status event message queue (corresponding to "output to line status event message queue" in fig. 2).
It should be noted that the online and offline event data are obtained based on calculation processing of heartbeat data from the device side, and compared with an online and offline change event directly uploaded by the device side, the online state judgment is more objective and the obtained data are more accurate. In addition, in practice, some devices cannot objectively report their off-line states in real time, and by adopting the implementation mode of the application, the devices can be judged, in other words, more comprehensive data can be obtained.
Further, in this embodiment, the method further includes:
filtering the device online state event data stream according to the online event data and the offline event data, and respectively and correspondingly outputting the online event data stream and the offline event data stream;
and correspondingly publishing the online event data stream and the offline event data stream to an online event message queue and an offline event message queue (corresponding to "output to online event message queue" and "output to offline event message queue" in fig. 2, respectively).
In this embodiment, as shown in fig. 2, the method further includes:
and sorting the equipment online state event data stream and the equipment state data stream according to the data time information, merging and outputting the data streams into an online state event and data mixed stream (corresponding to the 'aggregated online state event and data mixed stream' in fig. 2), and issuing the online state event and data mixed stream to an online state event and data mixed message queue (corresponding to the 'output to the online state event and data mixed message queue' in fig. 2).
It is easily understood that the data time information herein refers to the generation time of the state data and the generation time of the event data.
In this embodiment, a total of 7 different types of data streams, which are an online status data stream, an offline status data stream, an equipment status data stream, an online event data stream, an offline event data stream, an online status event data stream, and an online status event and data mixed stream, may be output to the corresponding message queues. The method and the device are used for selecting subscription according to needs in each relevant scene, and then directly participate in logic calculation in a service scene, so that the application scene is prevented from further processing the online state data of the equipment according to the service requirements, and the difficulty of using the online state data in most scenes and the coupling between services can be reduced.
And further, in practical application, comprehensive equipment online data form selection can be provided for various scenes. For example, if the device is continuously concerned about being online, the online status data flow message can be subscribed; if the offline condition of the equipment is continuously concerned, the offline state data stream message can be subscribed; if the continuous device online state is concerned, the device online state data stream message can be subscribed; if the online event is concerned, the online event data stream message can be subscribed; if the offline event is concerned, the offline event data stream message can be subscribed; if the online state change is concerned, the online state event information flow message can be subscribed; the mixed streaming messages of presence events and data can be subscribed to if event change and persistent data are of interest and higher accuracy.
In the technical scheme of the application, based on the comparison reference of different output data streams, when the device offline state can be further distinguished and definitely not receiving the device online data, the device offline state is not received due to data packet loss caused by problems such as network communication environment and the like, or the device is in the offline state at the moment, so that the more comprehensive device online state can be obtained in the technical scheme of the application.
In this embodiment, based on the specific configuration, these output data streams include device id, data stream type, data type, presence status, event type, time, etc., for example, the data stream type is used to distinguish 7 different forms of output data streams; the data types are divided into timing types and event types, and the timing data and the event data are distinguished; the online state is divided into online state and offline state, and the online state of the current data is distinguished; the event types are divided into an online type and an offline type, and the event state of the current data is distinguished.
