Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a block diagram illustrating a 5G communication edge computing device for power control and collection service according to an embodiment of the present invention. In fig. 1, the computing device may include a first communication module 01, a second communication module 11, a first service data encryption module 02, a second service data encryption module 12, a wireless signal probe module 03, a first service data edge calculation module 04, a second service data edge calculation module 14, and a service port switching module 05.
In fig. 1, the first communication module 01 and the second communication module 11 may be configured to receive external power distribution network state acquisition-type service information, and send the processed service information to a control center of a distribution network monitoring end. The first service data encryption and decryption module 02 and the second service data encryption and decryption module 12 are respectively connected with the first communication module 01 and the second communication module 11, and are used for encrypting and decrypting service information for communicating with the control center. The wireless signal probe module 05 can be connected with the first communication module 01 and the second communication module 11, and is used for acquiring the current effective bandwidth of information transmission of the first communication module 01 and the second communication module 11. The first service data edge calculation module 04 and the second service data edge calculation module 14 may be connected to the first communication module 01 and the second communication module 11, respectively, for processing service information. The service port switching module 05 may be connected to the wireless signal probe module 03, the first communication module 01, the second communication module 11, the first service data encryption and decryption module 02, the second service data encryption and decryption module 12, the first service data edge calculation module 03, and the second service data edge calculation module 13, and is configured to dynamically allocate a calculation amount of current service information.
In the computing apparatus shown in fig. 1, in order to split the service information into a plurality of sub-sequences, so that a processing task can be dynamically allocated to the current states of the first communication module 01, the second communication module 11, the first service data edge calculation module 04, and the second service data edge calculation module 14 during operation, the first service data encryption/decryption module 02 and the second service data encryption/decryption module 12 may perform a decryption operation on the received service information, and assign a time sequence to the decrypted service information, so as to obtain a service information time sequence of the service information with respect to the time length.
Since the service port switching module 05 is connected to the first service data encryption and decryption module 02 and the second service data encryption and decryption module 12, after receiving the two service information time sequence sequences, the service port switching module 05 may first perform a time sequence alignment operation on the service information time sequence sequences transmitted by the first service data encryption and decryption module 02 and the second service data encryption and decryption module 12 to obtain a complete service information time sequence.
The first service data edge calculation module 04 and the second service data edge calculation module 14 may both be configured to process the service information timing sequence. However, in the actual process of processing, due to the difference between the devices used by the first service data edge calculation module 04 and the second service data edge calculation module 14, and in the process of calculation, due to factors such as heat dissipation, the current calculation frequencies of the first service data edge calculation module 04 and the second service data edge calculation module 14 may be different. At this time, in order to utilize the computing resources of the first service data edge computing module 04 and the second service data edge computing module 14 most efficiently, the service port switching module 05 may first obtain the current computing frequency of the first service data edge computing module 04 and the second service data edge computing module 14; then calculating the distribution factors of the first service data edge calculation module 04 and the second service data edge calculation module 14 according to formula (1) and formula (2),
wherein, γ 1 、γ 2 Distribution factors, CPU, of the first service data edge calculation module 04 and the second service data edge calculation module 14, respectively 1 And a CPU 2 The current calculation frequencies of the first service data edge calculation module 04 and the second service data edge calculation module 14, respectively.
After calculating the distribution factors of the first service data edge calculation module 04 and the second service data edge calculation module 14, the service port switching module 05 may be configured to divide the complete service information time sequence into a plurality of subsequences; reading the subsequences in sequence according to the time sequence; and finally, selecting the first service data edge calculation module 04 and the second service data edge calculation module 14 according to the distribution factor so as to process the subsequences.
The first communication module 01 and the second communication module 11 receive external service information, and on the other hand, need to transmit processed service information to the outside. However, due to the positions of the first communication module 01 and the second communication module 11, the interference of different signal sources, the fluctuation characteristics of networks of different systems, and other factors, when the computing device actually works, the uploading speeds of the first communication module 01 and the second communication module 11 may have a relatively obvious difference. In this embodiment, therefore, the service port switching module 02 may be configured to calculate the integrated bandwidth weights of the first communication module 01 and the second communication module 11 according to the formula (3) and the formula (4),
wherein ξ 1 、ξ 2 The integrated bandwidth weights, δ, of the first communication module 01 and the second communication module 11, respectively x For correction factors related to the priorities of the first communication module 01 and the second communication module 11, trans 01 、Trans 11 Current effective bandwidth, epsilon, of the first communication module 01 and the second communication module 11, respectively 01 、ε 11 Weight factors, trans, for the current effective bandwidth of the first communication module 01 and the second communication module 11, respectively 02 、Trans 12 Theoretical bandwidths, ε, of the first communication module 01 and the second communication module 11, respectively 02 、ε 12 A weighting factor of the theoretical bandwidth of the first communication module 01 and the second communication module 11.
After calculating the comprehensive bandwidth weights of the first communication module 01 and the second communication module 11, the service port switching module 05 may be first configured to read the subsequence of the processed service information time sequence according to a time sequence; and then, distributing the subsequences according to the comprehensive bandwidth weight to control the first communication module 01 and the second communication module 11 to send the processed service information time sequence to the outside.
In addition, in order to ensure that the computing device can acquire the environmental conditions of the distribution network equipment site in real time, so as to complete the integration calculation of the service data (i.e. data integration operation), as shown in fig. 2, the computing device may further include a service data acquisition module 06. The service data acquisition module 06 may be connected to the first service data edge calculation module 04 and the second service data edge calculation module 14, and is configured to be externally connected to sensors on a plurality of distribution network devices to receive data acquired by the sensors.
In another aspect, the invention further provides a 5G communication edge computing system for power control and collection service, where the computing system includes sensors disposed on a plurality of distribution network devices on the site and a computing device as described in any one of the above.
Through the technical scheme, the 5G communication edge computing device and the system for the power control and acquisition service, which are provided by the invention, dynamically allocate the service information time sequence of the service information by arranging the first communication module and the second communication module and adopting the service port switching module. Compared with a simple port switching mode in the prior art, the current network of two communication modules can be utilized to the maximum extent. In addition, the computing device and the computing system have higher data processing efficiency due to the fact that processing tasks are dynamically distributed between the first service data encryption and decryption module and the second service data encryption and decryption module aiming at the service information time sequence.
