Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and in particular to a dynamic concurrent acquisition method, system, equipment and medium for a power line carrier concentrator. Background Art

[0002] In the field of electricity information collection, a typical collection scheme is to install an electricity information collection concentrator at the location of the distribution transformer to manage the smart energy meters of all users under the distribution transformer and collect the electricity information of each user. For a long time in the past, PLC communication technology has been widely used in the downlink communication of the electricity information collection concentrator (i.e., the communication between the concentrator and each smart energy meter), and has played a great economic benefit. Therefore, in the future, PLC communication technology will still be one of the main communication methods in the field of electricity information collection. However, in the minds of electricity information collection terminal manufacturers, PLC communication technology is a low-speed communication technology that is not enough to support the concentrator to communicate with multiple smart energy meters at the same time. Therefore, the traditional design is that the concentrator communicates with the smart energy meters it manages one by one to complete the electricity information collection. The communication process with each smart energy meter is a "one question and one answer" method.

[0003] In fact, there is a certain response time between the smart energy meter receiving the "inquiry message" from the concentrator and sending the "response message", such as Figure 1 As shown in the figure, while the concentrator is waiting for the "response message", the collection task inside the concentrator is idle, and the communication medium of the PLC is also idle, so the time resources during this period are wasted. This seriously restricts the collection efficiency of the concentrator and the scale of network management. Summary of the invention

[0004] In view of this, the present invention provides a dynamic concurrent collection method, system, device and medium for a power carrier concentrator, which dynamically senses the optimal concurrent number in different environments or at different times so that the concentrator can maintain the best collection effect and efficiency when working in various environments.

[0005] The present invention discloses a dynamic concurrent acquisition method for a power line carrier concentrator, which comprises:

[0006] A power consumption information collection concentrator is installed at the distribution transformer location to manage the smart energy meters of all users under the distribution transformer and collect the power consumption information of each user; the concentrator communicates with multiple smart energy meters at the same time; the concentrator sends an inquiry message to the smart energy meter, and the time required for the smart energy meter to receive the inquiry message and feed back a response message to the concentrator is taken as the response time; the concentrator sends the inquiry message to other smart energy meters at the same time within the response time.

[0007] Furthermore, the concentrator sends an inquiry message to each smart energy meter. After receiving the inquiry message, the smart energy meter prepares data, that is, feeds back the power consumption information of the user corresponding to the smart energy meter to the concentrator.

[0008] Furthermore, a sliding method is used to dynamically calculate the concurrent number of inquiry messages sent by the concentrator to the smart electric energy meter.

[0009] Furthermore, the slip period is defined as t, and the number of concurrent update periods is defined as n, then the concurrent update period is:

[0010] T=t*n

[0011] That is, after each slip cycle t time, a concurrent value C is updated according to the communication situation in the previous T time.

[0012] Furthermore, the concurrency value C is calculated:

[0013] Assume that within a sliding window time T, the total number of query messages sent by the concentrator is m, and the time it takes for each query message to be successfully sent is d. m The time from the sending of each inquiry message to the receiving of the response message fed back by the smart energy meter is r m , then the concurrency value corresponding to the sliding window time is:

[0014]

[0015] The present invention also discloses a dynamic concurrent acquisition system for a power carrier concentrator, which implements any of the above-mentioned dynamic concurrent acquisition methods for a power carrier concentrator, and comprises:

[0016] A response module, used for the concentrator to send an inquiry message to the smart energy meter, and the time required for the smart energy meter to feed back a response message from receiving the inquiry message to the concentrator is used as the response time;

[0017] The sending module is used for the concentrator to send inquiry messages to other smart energy meters simultaneously within the response time.

[0018] The present invention also discloses a dynamic concurrent acquisition device of a power line carrier concentrator, which comprises:

[0019] Memory for storing computer programs;

[0020] A processor is used to implement the dynamic concurrent acquisition method of the power carrier concentrator described in any one of the above items when executing the computer program.

[0021] The present invention also discloses a readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the dynamic concurrent acquisition method of the power carrier concentrator described in any one of the above items is implemented.

[0022] Due to the adoption of the above technical scheme, the present invention has the following advantages: it is mainly aimed at the power consumption information collection concentrator whose downlink communication mode is PLC, and focuses on improving the data collection efficiency of the concentrator by introducing a concurrent communication mechanism. It dynamically senses the optimal concurrent number in different environments or at different times so that the concentrator can maintain the best collection effect and efficiency when working in various environments.

[0027] The present invention is further described in conjunction with the accompanying drawings and embodiments, and the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field should fall within the scope of protection of the embodiments of the present invention.

[0028] The present invention proposes a concurrent collection method for sending "inquiry messages" to one or more other smart energy meters while waiting for the first smart energy meter to reply to the "response message", and the number of concurrent messages can be dynamically adjusted according to changes in communication quality, communication delay, and meter response time. Figure 2 As shown (taking the concurrent number of 3 as an example).

[0029] The present invention provides an embodiment of a dynamic concurrent acquisition method of a power line carrier concentrator, which comprises:

[0030] A power consumption information collection concentrator is installed at the distribution transformer location to manage the smart energy meters of all users under the distribution transformer and collect the power consumption information of each user; the concentrator communicates with multiple smart energy meters at the same time; the concentrator sends an inquiry message to the smart energy meter, and the time required for the smart energy meter to receive the inquiry message and feed back a response message to the concentrator is taken as the response time; the concentrator sends the inquiry message to other smart energy meters at the same time within the response time.

[0031] In one embodiment, the concentrator sends an inquiry message to each smart energy meter. After receiving the inquiry message, the smart energy meter prepares data, that is, feeds back the power consumption information of the user corresponding to the smart energy meter to the concentrator.

[0032] In actual situations, the following factors are uncertain: the time it takes for an inquiry message to be sent from the concentrator to the meter varies with the quality of the communication link and the length of the communication path; the time it takes for an inquiry message to be sent from the concentrator to the meter may also vary at different times; the meter's response delay varies with the meter type or manufacturer; because of these uncertainties, it is difficult to set a concurrency value that can achieve optimal efficiency when integrated with any meter at any time.

[0033] In view of this, in one embodiment, the present invention adopts a sliding method to dynamically calculate the concurrent number of inquiry messages sent by the concentrator to the smart electric energy meter.

[0034] In one embodiment, the slip period is defined as t, and the number of concurrent update periods is defined as n. Then, the concurrent update period is:

[0035] T=t*n

[0036] That is, after each slip cycle t time, a concurrent value C is updated according to the communication situation in the previous T time, such as Figure 3 shown.

[0037] In one embodiment, the concurrency value C is calculated:

[0038] Assume that within a sliding window time T, the total number of query messages sent by the concentrator is m, and the time it takes for each query message to be successfully sent is d. m The time from the sending of each inquiry message to the receiving of the response message fed back by the smart energy meter is r m , then the concurrency value corresponding to the sliding window time is:

[0039]

[0040] The present invention also provides an embodiment of a dynamic concurrent acquisition system for a power carrier concentrator, which implements the dynamic concurrent acquisition method for a power carrier concentrator described in the above embodiment, and includes:

[0041] A response module, used for the concentrator to send an inquiry message to the smart energy meter, and the time required for the smart energy meter to feed back a response message from receiving the inquiry message to the concentrator is used as the response time;

[0042] The sending module is used for the concentrator to send inquiry messages to other smart energy meters simultaneously within the response time.

[0043] The present invention also provides an embodiment of a dynamic concurrent acquisition device of a power line carrier concentrator, which includes:

[0044] Memory for storing computer programs;

[0045] The processor is used to implement the dynamic concurrent data collection method of the power carrier concentrator described in the above embodiment when executing the computer program.

[0046] The present invention also provides an embodiment of a readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the dynamic concurrent acquisition method of the power carrier concentrator described in the embodiment is implemented.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents.
