Detailed Description
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a charging facility data transmission dynamic control method and system, which are used for solving the technical problem of poor transmission processing capability caused by the fact that an existing data processing system distributes and processes data in a fixed message queue mode under the condition of high concurrency of mass data.
Referring to fig. 1 and fig. 3, a first embodiment of the present application provides a method for dynamically controlling data transmission of a charging facility, including:
and step 100, receiving a remote signaling and telemetry data message sent by the charging pile equipment, and sending the remote signaling and telemetry data message to a message queue for caching.
It should be noted that, each message queue of this embodiment is used as a transmission "bridge" between the data acquisition node and the background monitoring system, and in the transmission process, by monitoring the buffer message amount of the message queue, when it is detected that the buffer message amount in the message queue is greater than a preset first message amount threshold and the out-of-limit accumulated time exceeds a preset first time threshold, it is indicated that the processing capability of the message queue is insufficient, and then, it is necessary to determine the message queues with insufficient processing capability, that is, the first target message queue, and acquire the attribute parameter of the first target message queue, where the attribute parameter of this embodiment may include: queue data length, data throughput rate, and other queue basic attributes.
And step 102, establishing an extended message queue according to the attribute parameters, and improving the data distribution throughput rate, wherein the attribute parameters of the extended message queue are consistent with the target message queue.
It should be noted that, according to the attribute parameter of the first target message queue, an extended message queue whose attribute parameter is consistent with that of the target message queue is established, so that data distribution is performed through cooperation between the extended message queue and the original message queue, so as to improve the overall data throughput of the message queue and accelerate the efficiency of data transmission.
According to the control method, the number of the message queues is controlled according to the message storage amount of the message queues for data distribution and transmission, the number of the message queues is dynamically expanded under the condition of mass data concurrency, the data transmission capability is enhanced, and the technical problem that the transmission processing capability is poor due to the fact that the existing data processing system adopts a fixed message queue mode to distribute and process data under the condition of high mass data concurrency is solved.
The above is a detailed description of a first embodiment of a charging facility data transmission dynamic control method provided by the present application, and the following is a detailed description of a second embodiment of a charging facility data transmission dynamic control method provided by the present application.
Referring to fig. 2, a second embodiment of the present application provides a dynamic control method for data transmission of a charging facility based on the first embodiment of the present application, which specifically includes:
It should be noted that, before the extended message queue is established, the first target message queue determined in step 101 may be classified according to the queue type parameter in the attribute parameter, so as to obtain a first message queue type set, where it is understood that the number of the first message queue type sets is related to the number of the first target message queue determined in step 101, if the first target message queue has only one object, which is equivalent to only one type of queue, the number of the first message queue type sets is also 1, and if the first target message queue has two objects, that is, if the first target message queue includes one or two types of queues, the number of the first message queue type sets is 1 or 2.
And 1022, determining the upper limit value of the queue number corresponding to each first message queue type set according to the corresponding relationship between the preset queue type parameter and the upper limit value of the queue number.
It should be noted that, according to the preset corresponding relationship between the queue type parameter and the upper limit of the queue number, the upper limit of the queue number corresponding to each first message queue type set is determined. The message queue type of this embodiment sets an upper limit value of the queue number, which is used to limit the number of the message queues corresponding to each message queue type to be not greater than the upper limit value, and the upper limit value may be set by a user, which is not described herein.
And 1023, quantitatively establishing a plurality of extended message queues according to the attribute parameters and the queue number upper limit value corresponding to each message queue type set, so that the number of the message queues of the same type is not greater than the queue number upper limit value.
It should be noted that, after the upper limit of the number of queues corresponding to each set of message queue types is determined, the number of the extended message queues is determined according to the difference between the number of message queues corresponding to each set of message queue types and the upper limit of the number of queues, so that the number of message queues of the same type added with the number of the extended message queues is not greater than the upper limit of the number of queues of the queue type.
And then establishing an extended message queue with the attribute parameters consistent with the target message queue according to the attribute parameters of the first target message queue.
Further, after step 102 of the first embodiment of the present application, the method further includes:
and 103, when the message buffer amount in the message queue and/or the expanded message queue is detected to be zero and the idle accumulated time exceeds a preset second time threshold, determining a second target message queue. The second target message queue is a message queue and/or an extended message queue, the message buffer amount is zero, and the idle accumulated time exceeds a preset second time threshold;
and step 104, destroying the second target message queue.
It should be noted that, after the transmission capability is enhanced by establishing the extended message queue, after a message peak time period elapses, the message volume is greatly reduced, and at this time, the system resources are occupied by excessive message queues, which increases the system load, and at this time, the occupied system resources can be released by determining the idle second target message queues and destroying the message queues.
Further, step 104 of this embodiment specifically includes:
And 1043, quantitatively destroying the second target message queues according to the lower limit value of the queue number corresponding to each message queue type set, so that the number of the message queues of the same type is not less than the lower limit value of the queue number.
It should be noted that, as in the first target message queue, this embodiment may further include, in addition to having the upper limit value of the queue number: and the lower limit value of the queue number is used for ensuring that each type of message queue at least keeps a certain number and ensuring the integrity of the message queue type.
In this embodiment, by monitoring the operation conditions of the message queue, including the number of queues, the queue length, the queue throughput, and associating the data of specific data characteristics with the corresponding relationship between the queues, the data queue with high importance has control measures such as redundancy and backup. The queue is a first-in first-out linear table, and the data enqueued and dequeued by the independent queues have the same data characteristics. When the queue control service monitors that the queue length of a certain type of data queue exceeds a specified threshold value and lasts for a certain time, the current data processing capacity is judged to be insufficient, new queue management needs to be applied to participate in data distribution, and after the application is successful, the data type and the queue are registered, so that the data processing service can provide calling for a distribution processing module and the data processing service. When the queue control service monitors that the idle of a certain type of data queue exceeds a specified threshold value, the queue is recycled and destroyed, resources are released, and the system overhead is reduced.
Further, this embodiment may further include, before step 101:
1001, performing data analysis according to the received remote signaling and telemetry data message to obtain a data type of the remote signaling and telemetry data message;
It should be noted that, after receiving the remote signaling telemetry data message collected from the entity device, according to the communication protocol analysis, according to the data type of the remote signaling telemetry data message, in combination with the preset corresponding relationship between the data type and the queue type parameter, the remote signaling telemetry data message is distributed to the specific type of message queue, i.e., the third target message queue, so as to implement the data distribution processing.
Further, before step 1002, the method may further include:
And step 1004, transferring the remote signaling telemetry data message to an abnormal data cache library.
It should be noted that, in this embodiment, an abnormal data buffer library is further provided, when the data amount is very large, which causes the data buffered in the message queue to reach the maximum message amount threshold and the total amount of the third target message queue to be smaller than the upper limit of the queue number, and the extended message queue cannot be established, in order to prevent the telecommand telemetry data message that is not stored in the message queue from being lost when the received data is refreshed, the telecommand telemetry data message may be sent to the abnormal data buffer library of this embodiment for buffering, so that the problem of data jam after accumulation is solved, and the integrity of the acquired data is ensured.
The above is a detailed description of the second embodiment of the charging facility data transmission dynamic control method provided by the present application, and the following is a detailed description of the first embodiment of the charging facility data transmission dynamic control method provided by the present application.
Referring to fig. 3, a third embodiment of the present application provides a charging facility data transmission dynamic control system, which includes a message receiving module, a queue control module, and a message queue transmission module;
the message queue transmission module comprises a plurality of message queues;
the message receiving module is specifically used for receiving a remote signaling and telemetry data message sent by the charging pile equipment and sending the remote signaling and telemetry data message to a message queue for caching;
the queue control module is specifically configured to, when it is detected that the amount of the buffered messages in the message queue is greater than a preset first message amount threshold and the out-of-limit accumulation time exceeds a preset first time threshold, acquire an attribute parameter of a first target message queue, where the first target message queue is a message queue in which the amount of the buffered messages in the message queue exceeds the preset message amount threshold and the out-of-limit accumulation time exceeds the first time threshold, and establish an extended message queue for data transmission according to the attribute parameter, where the attribute parameter of the extended message queue is consistent with the target message queue.
Further, the queue control module is further configured to:
and when the message buffer amount in the message queue and/or the expanded message queue is detected to be zero and the idle accumulated time exceeds a preset second time threshold, determining a second target message queue, wherein the second target message queue is a message queue and/or an expanded message queue, the message buffer amount is zero, the idle accumulated time exceeds the message queue with the preset second time threshold, and destroying the second target message queue.
It should be noted that the queue control module, the message queue module, and the independent message queue of this embodiment constitute a data distribution model. The queue control module monitors the running condition of the message queue module, and comprises the number of message queues, the length of the message queues, the throughput rate of the message queues, and the corresponding relation between data related to specific data characteristics and the message queues. The message queue is a first-in first-out linear table, and the data enqueued and dequeued by the independent message queue has the same data characteristic. When the queue control module monitors that the length of distributed data in a certain type of data message queue exceeds a specified warning threshold value and lasts for a certain time threshold value, the processing capacity of the current certain type of data pipe section is judged to be insufficient, new management needs to be applied to participate in data distribution, after the data is successfully applied, the data type and the message queue are registered, the data processing module can provide calling for the distribution processing module and data processing service, the maximum and minimum message queue number can be configured for each type of data message queue independently, the maximum message queue number is the maximum number for processing certain type of data message queues, and the application cannot be continued after the capacity expansion reaches the maximum number. If the data length in the single message queue exceeds the specified rejection threshold value, the rejection strategy is started, the message queue stops receiving the data, and the distribution processing module distributes the data rejected to the abnormal data cache bank for processing. When the queue control module monitors that the time when the length of a certain type of data message queue is zero exceeds a specified idle threshold value, the message queue is recycled and destroyed, resources are released, and the system overhead is reduced until the idle message queue of a certain data type is not destroyed after the minimum number of the message queues is reached. The message queue module realizes the operations of creating, destroying, maintaining the state of the message queue, pushing the data in the message queue, reading the data in the message queue and the like, each data type can correspond to a plurality of message queues to realize the load balance of data distribution, the message queue number and the throughput can be self-adapted along with the concurrent transmission of the data acquisition service by dynamically adjusting the message queue of the message queue module, the flexibility and the processing timeliness of the system are enhanced, and the message queue distribution efficiency can be preferentially ensured for the service data with high real-time requirement.
Further, still include: and the distribution processing module is used for carrying out data analysis according to the received remote signaling and remote measuring data message to obtain the data type of the remote signaling and remote measuring data message, and distributing the remote signaling and remote measuring data message to a corresponding third target message queue according to the preset corresponding relation between the data type and the queue type parameter.

Further, still include: and the transfer judging module is used for judging whether the cache message amount in the third target message queue is smaller than a preset maximum message amount threshold value or not, judging whether the total amount of the third target message queue is smaller than an upper limit of the queue amount or not, and transferring the remote signaling and remote measuring data message to the abnormal data cache library if the total amount of the third target message queue is not smaller than the upper limit of the queue amount.
It should be noted that the abnormal data cache library of this embodiment may obtain the current queue blocking data and the abnormal data, and process the queue blocking data by using various means such as real-time library caching, database persistence, and the like, so as to meet the requirement of data integrity.
More specifically, the data node cluster shown in fig. 3 is a data uploading node set formed by a large number of charging facilities, and is a source for collecting system data, the charging facilities establish communication after registering with the traffic monitoring service, and are connected with each other in a long Socket protocol, and the charging facilities upload remote signaling, remote measuring, and service data communication messages periodically or in a burst manner. The flow monitoring module is used for managing the flow of the charging facility and the safety of the data uploading, and a monitoring algorithm of the flow monitoring module is based on updating and detecting the message frequency and counting the delivery data flow value of the equipment in a fixed time window according to a certain time interval. When the interaction frequency detection exceeds the threshold or the flow exceeds the threshold, the flow monitoring service judges that the equipment is abnormal, the connection with the equipment is actively disconnected, the equipment is listed in a temporary blacklist, the charging facility limits the equipment to send message data within a certain period until the blacklist is removed, and the disturbance of the abnormal movement of the charging equipment to the system is avoided.
