Detailed Description
The objects, technical solutions and advantages of the present invention will become more apparent by the following detailed description of the present invention with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the invention. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present invention.
Example 1
An embodiment of the present invention provides an optimized communication method for dual-mode fusion of a power line carrier and wireless, as shown in fig. 1. Transmitting data information by optimizing networking to a first dual-mode communication unit and a second dual-mode communication unit through power line carrier communication or wireless communication, the method comprising:
S101, sending an acquisition task and acquiring received signal strength data RSSI and signal to noise ratio data SNR of power line carrier communication and wireless communication,
S102, evaluating the communication performance to be networked through the signal-to-noise ratio data and the received signal strength data,
S103, establishing connection between the first dual-mode communication unit and the second dual-mode communication unit through a network with better communication performance, and
S104 transmitting data information over the established connection,
In one embodiment, the performance of the to-be-networked communication is assessed by the formula (1):
Wherein m represents a first dual-mode communication unit, and n represents a second dual-mode communication unit; representing an evaluation value of network-to-be-networked communication performance between the first and second dual-mode communication units; /(I) Representing the received signal strength between the first and second dual-mode communication units at time t; /(I)Representing the signal to noise ratio between the first and second dual mode communication units at time t; /(I)Is a weight coefficient; where x=p or r, p represents power line carrier communication, r represents wireless communication,
When evaluating the communication performance of the power line carrier to be accessed to the network, the signal to noise ratio is more focusedFor example 0.4 or 0.3.
When evaluating the performance of wireless communication to be entered into the network, the received signal strength is more focusedFor example 0.5 or 0.6.
The RSSI represents the received signal strength (RECEIVED SIGNAL STRENGTH Indicator), which is an Indicator for measuring the received signal strength. Generally in dBm, a larger value indicates a stronger signal strength. The RSSI does not take into account the influence of signal quality, but reflects only the strength of the signal.
SNR stands for Signal-to-Noise Ratio (SNR), which is an indicator of the Ratio between Signal and Noise. Usually expressed in dB, a larger value indicates a better signal quality. The higher the SNR, the higher the ratio of useful information in the signal to noise, and the better the communication quality.
By comprehensively evaluating the quality of the network to be accessed by using the RSSI and the SNR, more objective and more accurate evaluation results can be obtained in some cases. There is a certain correlation between these two metrics. In most cases, the stronger the received signal strength, the better the SNR will generally be, so RSSI alone may also be used to evaluate the network quality to be entered, as demonstrated by some embodiments of the present invention, such as example two below. However, the RSSI considers only the signal strength, but ignores the influence of noise, interference, and other factors, so that the RSSI may not fully reflect the quality of the signal in some cases.
Further, in the method of the present embodiment, the performance of the communication to be networked between the concentrator and the electricity meter is reevaluated every time within 30 minutes (for example, every time of 20 minutes, 15 minutes, 10 minutes, 5 minutes, 1 minute, 30 seconds, 20 seconds, 10 seconds, etc., but not limited thereto).
Example two
The invention provides an application of the power line carrier and wireless dual-mode fusion optimization communication method between specific communication nodes. As shown in fig. 2, the optimization method is based on a first node 100 and a second node 200, the second node 100 comprising a first processing unit 110 and a first dual-mode communication unit 120, the second node 200 comprising a second processing unit 210 and a second dual-mode communication unit 220; the first dual mode communication unit 120 includes a networking control module 121, and the networking control module 121 enables the first dual mode communication unit 120 and the second dual mode communication unit 220 to transmit user power consumption data information through power line carrier communication (PLC) or wireless communication (RF) by optimizing networking.
The optimization method comprises the following steps: the first processing unit 110 transmits an acquisition task to the second node 200 and acquires Received Signal Strength (RSSI) data and signal-to-noise ratio (SNR) data of dual mode communications (power line carrier communications and wireless communications such as PLC and RF); the networking control module 121 evaluates the communication performance of the network to be accessed (i.e., the power line carrier network and the wireless network) through the SNR data and the RSSI data; the connection between the first dual-mode communication unit 120 and the second dual-mode communication unit 220 is established through a network with better communication performance, and data information in the second node 200 is adopted, wherein the second processing unit 210 is used for collecting metering and data processing of the information so as to obtain specific data information to be uploaded.
Example III
The embodiment provides an optimized communication method for fusion of a power line carrier and a wireless dual mode, which further comprises, based on the optimized method of the embodiment: judging the current network working environment according to the detected current network communication condition within the first set time, and switching the current network to be wireless communication if the current network is power line carrier communication and the packet loss rate is higher than a first set threshold value; and if the current network is wireless communication and the packet loss rate is higher than a second set threshold value, switching the current network to be power line carrier communication. The first set time is not more than 10 minutes (e.g., 8 minutes, 6 minutes, 5 minutes, 3 minutes, 2 minutes, 1 minute, 30 seconds, 20 seconds, 10 seconds, etc., but is not limited thereto). Preferably, the first set threshold for power line carrier communication is smaller than the second set threshold for wireless communication.
Example IV
The invention provides a method for selecting a communication network with better communication performance to establish a connection example between dual-mode communication units by adopting an adaptive network selection algorithm to compare RSSI values of wireless communication and power line carrier communication in three stages.
As shown in fig. 3, the comparing RSSI values of wireless communication and power line carrier communication in three stages includes:
The first stage: firstly judging the RSSI value of wireless communication, selecting a wireless communication mode to transmit data if the RSSI value is larger than or equal to-70 dBm, otherwise judging the RSSI value of power line carrier communication, selecting the power line carrier communication mode to transmit data if the RSSI value is larger than or equal to 16dBm, and entering a second stage to select if the RSSI value is smaller than 16 dBm;
And a second stage: firstly judging the RSSI value of wireless communication, selecting a wireless communication mode to transmit data if the RSSI value is greater than or equal to-80 dBm, otherwise judging the RSSI value of power line carrier communication, selecting the power line carrier communication mode to transmit data if the RSSI value is greater than or equal to 12dBm, and entering a third stage to select if the RSSI value is less than 12 dBm;
