The specification may use the word "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments as per the application.
The embodiment of the application provides a data display method, which can be applied to electronic equipment such as a terminal and a server, and can specifically run in a dock or be deployed in a pod of k8s, as shown in fig. 1, and the method in the embodiment comprises the following steps:
Step S101, acquiring data packets of all equipment objects in real time based on an Internet of things platform, storing all the data packets into a preset target message queue, and deleting all historical data packets acquired at the last acquisition moment, wherein the data packets contain a plurality of point location data of the equipment objects;
in the specific implementation process, the IOT acquires real-time point location data of a distributed control system (namely a DCS system) through a data acquisition gateway, and then packetizes the point location data according to point location identifiers corresponding to the point location data and equipment identifiers of the equipment objects to which the point location data belong to obtain data packets corresponding to the equipment objects, so that the data packets can be pushed to a target message queue for storage, wherein the target message queue can be a Kafka message queue. The point location identifier may be a point location address (point location ID) or a point location name, etc., and the device identifier may also be a device address (device ID) or a device name, etc.
In this step, while storing the data packet in the Kafka target message queue, the historical data packet in the Kafka target message queue may be deleted, that is, the Kafka target message queue may store only the data packet at the current time.
In a specific implementation process, in order to backup the data packet, each historical data packet, an acquisition time corresponding to each historical data packet, and an equipment object corresponding to each historical data packet may be stored in a predetermined database in an associated manner, and then the historical data packet is deleted from the Kafka message queue.
Step S102, a target thread corresponding to each terminal device is configured to a configuration diagram queue corresponding to a target point position set in the corresponding terminal device in response to the target point position set which is sent by each terminal device and is to be subjected to data display and contains a plurality of target point position identifiers;
in the step, the target point location is the monitoring point location to be subjected to data display. That is, the terminal device or the client that needs to display the point location data may send the point location identifier of the monitoring point location/target point location to be displayed and the device identifier of the device object to which the monitoring point location/target point location to be displayed belongs to the middle server, so that the middle server may configure a corresponding target thread for the terminal device, and configure the target thread with the configuration diagram queue of the terminal. The point location identifier may be a point location address (point location ID) or a point location name, etc., and the device identifier may also be a device address (device ID) or a device name, etc.
In the implementation process, the plurality of terminal devices can simultaneously send the point location sets to be subjected to data display, and the middle platform service can simultaneously configure corresponding target threads for the terminal devices and configure the target threads to configuration diagram queues corresponding to the point location sets in the corresponding terminal devices, so that a foundation is laid for configuration diagram display of point location data of the plurality of subsequent terminal devices simultaneously.
Step S103, based on the target point location set sent by each terminal device, acquiring target data packets corresponding to the target point location set from the target message queue in real time, and forwarding each target data packet to a configuration diagram queue of a corresponding terminal device based on each target thread, so as to display each target point location data in the target data packet based on the configuration diagram queue.
In the implementation process, the middle station service can specifically acquire a plurality of point location data corresponding to each target point location set from the message queue according to each point location identifier in the target point location set, so as to construct and acquire a target data packet, that is, the plurality of target point location data contained in the target data packet corresponds to each target point location identifier in the target point location set one by one. After the target data packet is obtained, the target data packet can be sent to a configuration diagram queue of the corresponding terminal equipment through the target thread so as to display the data of each target point position in the target data packet, thereby completing the real-time display of the data.
According to the data display method, the data packets of the equipment objects are obtained in real time, then the data packets are stored in the message queue, the data packets in the message queue are updated in real time, therefore, the message queue only stores the data packets at the current obtaining time, the corresponding target data packets can be directly obtained from the message queue in the follow-up process, and are forwarded to the terminal equipment through the corresponding target route, and therefore the problems of low reading speed and easiness in error caused by reading the data packets at the current obtaining time from a mass database containing a plurality of obtaining times are solved, the data display is more accurate and reliable, and the data can be forwarded to a plurality of terminals at the same time, so that multi-mode display of the data is achieved.
Based on the foregoing embodiment, a further embodiment of the present application provides a data display method, in this embodiment, a specific acquiring process of a middle platform service when acquiring a data packet of each device object in real time based on an internet of things platform is as follows: acquiring point location data of each monitoring point location of each equipment object in real time based on an Internet of things platform; and based on the point location data, the point location identification of each monitoring point location and the equipment identification of the equipment object to which each monitoring point location belongs, packetizing the point location data to obtain a data packet which corresponds to each equipment object and contains a plurality of point location data. The point location identifier may be a point location address (point location ID) or a point location name, etc., and the device identifier may also be a device address (device ID) or a device name, etc. The internet of things platform can acquire real-time point location data of a distributed control system (namely a DCS system) through a data acquisition gateway, namely, point location data of all monitoring points of all equipment objects are acquired, and then the point location data of all the monitoring points are subjected to sub-packaging processing according to the point location address of each monitoring point and the equipment object to which the monitoring point location belongs, so that a data packet which corresponds to each equipment object and contains a plurality of point location data is acquired.
For example, there are a total of 3 device objects, device a, device B, and device C, respectively. Wherein, there are 2 monitoring points in equipment A, do respectively: point 1 and point 2. The equipment B has 2 monitoring points, which are respectively: point 3 and point 4. The device C has 3 monitoring points, which are respectively: point 5, point 6, and point 7. Therefore, the point data of the point 1, the point 2, the point 3, the point 4, the point 5, the point 6 and the point 7 can be obtained based on the internet of things platform at each obtaining time/collecting time, namely, the point data of each monitoring point is obtained in real time, and then the obtained 7 point data are subjected to the packetizing treatment according to the point address of the 7 points and the equipment address of the equipment object to which the 7 points belong, so that the point data 1' of the point 1 and the point data 2' of the point 2 are combined into a data packet corresponding to the equipment A, the point data 3' of the point 3 and the point data 4' of the point 4 are combined into a data packet corresponding to the equipment B, and the point data 5', the point data 6' of the point 5 and the point data 7' corresponding to the point 6 are combined into a data packet corresponding to the equipment C. In the implementation process of this embodiment, the acquisition time or the acquisition time may be set according to actual needs, for example, set to every second, every 2 seconds, etc.
Based on the above embodiment, another embodiment of the present application provides a data display method, in this embodiment, before configuring a target thread corresponding to the terminal device to a configuration diagram queue of the terminal device, a communication channel may be established in advance with the terminal device, and then a corresponding target thread is allocated to the communication channel, so as to lay a foundation for forwarding a data packet based on the target thread. The specific thread allocation process comprises the following steps: responding to a communication connection establishment request of the terminal equipment to establish a communication channel with the terminal equipment; and allocating a corresponding target thread for the communication channel based on each thread in the thread pool so as to configure the corresponding target thread for the terminal equipment. That is, the front-end (terminal device) configuration software may request to the intermediate service to establish a WebSocket connection handshake, that is, establish a long connection communication channel, and then the intermediate service may allocate a new thread from the WebSocket client thread pool to the long connection, so as to configure a corresponding target thread for the front-end (terminal device).
In this embodiment, in order to ensure that thread allocation is more reasonable and accurate, the same thread is prevented from being allocated to a plurality of communication channels at the same time, and when thread allocation is performed, threads can be allocated to the communication channels from the spare threads in the thread pool. That is, after the middle service establishes a communication channel with the terminal device, it may determine whether there are free threads in the thread pool; when the free threads exist, distributing corresponding target threads for the communication channels based on the free threads; when no free threads exist, creating a plurality of new threads based on the number of threads in the thread pool, so as to allocate corresponding target threads for the communication channel based on each new thread. By adopting the thread allocation scheme, the thread allocation can be more reasonable and accurate.
In this embodiment, before obtaining, in real time, a target data packet of each target device object from the target message queue, a middle station service may establish a communication connection with the target message queue in advance, so as to obtain, in real time, a target data packet corresponding to the target point location set from the target message queue by using the communication connection and based on a target point location set sent by each terminal device. In this embodiment, the middle platform service may use a multithreading technology to establish a communication connection with the target message queue Kafka, that is, subscribe to Kafak, so as to provide a guarantee for subsequent real-time acquisition of the data packet from the Kafka message queue.
In this embodiment, after the middle station service establishes a communication connection with the target message queue Kafka, the target data packet corresponding to the target point location set may be acquired from the target message queue in real time. Specifically, the acquisition process of the target data packet is as follows: the middle platform service determines a target equipment object to which each point mark in a target point position set belongs based on the target point position set sent by each terminal equipment; and then acquiring point location data corresponding to each point location identifier from the data packet corresponding to each target equipment object in real time, and merging the point location data to obtain a target data packet corresponding to the target point location set. After the target data packets are obtained, each target data packet can be forwarded to the configuration diagram queue of the corresponding terminal device based on each target thread.
That is, the middle station service unpacks the data packet corresponding to each target device object according to the target device object corresponding to each point bit identifier in the target set to obtain a point location data set corresponding to each target device, then filters the unpacked point location data set to obtain target point location data corresponding to the point location identifier, and finally aggregates and merges the target point location data to obtain the target data packet corresponding to the target point location set. For example, a certain device object a has a monitoring point 1 and a monitoring point 2, and a device object B has a monitoring point 3 and a monitoring point 4. The terminal equipment only needs to display the point position data of the monitoring point position 1 and the point position data of the monitoring point position 4. The terminal equipment combines the point location address of the monitoring point location 1 and the point location address of the monitoring point location 4 into a target point location set, and then sends the target point location set to the middle station service. When the middle station service obtains the data packet a of the equipment object A and the data packet B of the equipment object B from the Kafka message queue, unpacking processing can be respectively carried out on the two data packets to obtain a data set a 'and a data set B', and then the target point location data 1 'is obtained from the data set a' according to the point location identification of the monitoring point location 1. Similarly, the target point location data 4 'is obtained from the data set b' according to the point location identification of the monitoring point location 4. And then merging the target point location data 1 'and the target point location data 4', thereby obtaining a target data packet corresponding to the target set. The method lays a foundation for the subsequent terminal equipment to display the point position data of the monitoring point position 1 and the point position data of the monitoring point position 4 in a targeted manner.
In this embodiment, after a long connection is established between the middle server and the terminal device, the middle server may also receive a graph cutting request sent by the terminal device, where the graph cutting request includes a current point location set; the current point location set comprises point location identifiers of a plurality of different monitoring points; reconfiguring a target thread corresponding to the terminal equipment to a current configuration diagram queue corresponding to the current point location set in the terminal equipment; and acquiring a target data packet corresponding to the current point position set from the target message queue in real time based on the current point position set in the graph cutting request, and forwarding the target data packet to a current configuration graph queue of corresponding terminal equipment based on a target thread, so that the current configuration graph queue displays each point bit data in the target data packet.
After the terminal device sends the point location set including the target point locations for the first time, that is, the middle platform service pushes the target thread corresponding to the terminal device into the configuration diagram service topic of the corresponding ID (that is, the point location address) according to the point location set ID, thereby the middle platform service can push the real-time service data obtained from the message queue in seconds, that is, push the configuration diagram service of the corresponding device through the target thread, and display of the point location data is achieved. After the terminal equipment sends the point location address set again, the middle station service recognizes the point location address set as a graph cutting request, so that the middle station service can reenter a target thread corresponding to the terminal equipment into a new topic according to the point location set ID in the request, namely, the target thread is pushed to a configuration graph service topic with the point location address in the graph cutting request, and then data is pushed in the new topic in the next second, so that real-time switching among different configuration graph services is realized.
In the implementation process, in order to ensure that point location data display is performed on each configuration service graph of each terminal device stably and reliably, long connections in each configuration service topic queue can be scanned every second, and whether data suspension, graph cutting or data reissuing are needed or not is judged, and corresponding operations are executed. When the long connection state of the middle platform service and the terminal equipment is normal, the middle platform service can forward the target data packet to the configuration diagram queue topic of the corresponding terminal equipment in real time by utilizing the target thread.
In the application, the terminal equipment can receive the selection operation of the user for the point location identifiers to generate the corresponding configuration diagram queue topic based on the point location identifiers, and meanwhile, the terminal equipment also generates a point location set ID for the point location set formed by the point location identifiers, and the point location set ID is used as the identifier of the configuration diagram queue. That is, each terminal device may generate a configuration map queue topic based on the user's interaction.
