Hundreds of millions of electric meters across the country have entered the IoT communication to complete the massive collection of relevant electricity consumption information data. The most basic IoT communication is the data transmission communication between two user nodes, one sending and the other receiving. From a macro perspective, there are hundreds of millions of nodes communicating at any time.

[0003] According to the communication principle, in general, the stronger the signal, the more stable the reception. Naturally, if the signal exceeds the receiving threshold too much, the signal energy will be wasted. Therefore, for the communication between a huge number of nodes at every moment, it is possible to save energy by reasonably controlling the signal transmission power and reducing the energy consumption of the communication unit. In addition, IoT communication usually uses the same frequency resources for adjacent networks. Controlling the transmission power of the network can also effectively suppress the co-frequency interference to neighboring networks. In order to enhance the highly reliable transmission of communication in existing dual-mode communications, such as control or alarm data information, some nodes sometimes need to send simultaneously in both wireless and carrier communication modes.

[0020] In order to illustrate the technical solution of the present invention, a specific embodiment is used below for description, and only the parts related to the embodiment of the present invention are shown.

[0021] Embodiment 1: like Figure 1 As shown, the present invention provides a method for automatic control of transmission power applied to dual-mode communication, which is applied to the sender, and includes: S11, setting a plurality of transmission power levels, with a power level difference being set between two adjacent transmission power levels; S12, sending a data frame to the receiver according to the initial transmission power level, so that the receiver can interpret the data frame, determine whether the node of the receiver is the target address of the data frame, and if so, record the source address of the data frame, determine the reception signal quality mark according to the reception signal quality of the data frame and the reception control threshold value, and send a receipt data frame including the reception signal quality mark to the sender; S13, receiving and interpreting the receipt data frame, and adjusting the initial transmission power level of the next data frame sent to the receiver according to the received signal quality mark. Specifically, the sender can set multiple transmission power levels according to demand, and the setting of the transmission power level can be selected as level 1, level 2, level 3, level 4 and level 5. There is a power level difference between each two adjacent transmission power levels. The power level difference can be set according to the statistical analysis results of the communication system transmission and reception, and can be selected as 3 fourth level second level. Among the multiple transmission power levels that have been set, one is determined as the initial transmission power level. The initial transmission power level of the sender can be selected as level 3. When the sender sends a data frame to the receiver for the first time, it is sent according to the set initial transmission power level. The data frame sent by the sender includes information such as the source address, the destination address, and the current transmission power level. The sender records basic data information such as the transmission power level and the destination address while sending the data frame. The sender sends the data frame to the receiver for the receiver to interpret the data frame, determine the received signal quality mark and return it to the sender. After receiving the receipt data frame, the sender interprets it and automatically controls the initial transmission power level of the next data frame according to the received signal quality mark in the receipt data frame, so that the sender can transmit the next data frame to the receiver according to the initial transmission power level after control adjustment. The sender's subsequent initial transmission power level is based on the adjusted record, and after each transmission, the initial transmission power level is adjusted and recorded according to the received signal quality mark in the receipt data frame, so as to send the next data frame.

[0022] The present invention determines the signal quality of the data frame sent by the sender through the receiver, and then transmits the signal quality information of the data frame back to the sender, so that the sender adjusts and controls the initial transmission power level of the next data frame according to the signal quality of the previous communication, reasonably controls the signal transmission power, reduces the operating energy consumption of the communication, and saves energy. In addition, controlling the transmission power of the network can also effectively suppress the co-channel interference effect on the neighboring network.

[0023] As an optional implementation manner, adjusting the transmission power level of the next data frame sent to the receiving party according to the received signal quality flag includes: When the received signal quality mark is the first level, the initial transmission power level is adjusted upward by one level, an intermediate transmission power level for sending the next data frame to the receiving party is obtained, and the intermediate transmission power level is recorded; When the received signal quality mark is the second level or the third level, maintaining and recording the transmission power level of the next data frame sent to the receiving party; When the received signal quality mark is the fourth level, the initial transmission power level is adjusted downward by one level, the intermediate transmission power level for sending the next frame of data to the receiving party is obtained, and the intermediate transmission power level is recorded. Specifically, after the receiving party receives the receipt data frame, the initial transmission power level for sending the next frame of data is adjusted according to the received signal quality flag contained in the receipt data frame. The rule for adjusting the initial transmission power level for sending the next frame of data is as follows: When the received signal quality mark is the first level, it means that the signal quality of the data frame of the previous frame is weak, and the current initial transmission power level needs to be adjusted upward by one level as the initial transmission power level for sending the next frame of data to the receiving party. When the received signal quality mark is the second level or the third level, it means that the signal quality of the data frame of the previous frame is normal, and the current initial transmission power level needs to be maintained and recorded as the initial transmission power level for sending the next frame of data to the receiving party. When the received signal quality mark is the fourth level, it means that the signal quality of the data frame of the previous frame is strong, and the current initial transmission power level needs to be adjusted downward by one level as the initial transmission power level for sending the next frame of data to the receiving party.

[0024] As an optional implementation, the method further includes: if the received signal quality mark is the second level or the third level, determining that the transmission power level corresponding to the current data frame sent by the sender is the target transmission power level. Specifically, if the received signal quality mark is the second level or the third level, it means that the current communication is stable, and the transmission power level corresponding to the current data frame sent by the sender is determined to be the target transmission power level, and the sender transmits the data frame according to the target transmission power level. If the received signal quality mark is not the second level or the third level, it means that the current communication is unstable, and the receiver continues to record the current received signal quality mark, so that the sender can control and adjust the transmission power level according to the current received signal quality mark until the communication is stable.

[0025] As an optional implementation, the method further includes: if the receipt data frame is not received within the preset time, the transmission power level of the data frame is adjusted upward by one level on the basis of the initial transmission power level, and retransmitted. Specifically, if the sender does not receive the receipt data frame within the preset time, the sender adjusts the initial transmission power level upward by one level, and then retransmits the data frame to the receiver according to the adjusted transmission power level, so as to improve the communication quality of the next transmission. The preset time is the normal waiting time for receiving the receipt frame, and can be adaptively set according to the time requirements.

[0026] As an optional implementation, the method further includes: In dual-mode communication, according to the transmission power level of the wireless communication mode and the transmission power level of the power line broadband carrier communication mode, respectively determine the proportion of the transmission power level of the wireless communication mode and the transmission power level of the power line broadband carrier communication mode to the transmission power limit of the sender; Determine whether the sum of the ratio of the transmission power level of the wireless communication mode to the transmission power limit of the sender and the ratio of the transmission power level of the power line broadband carrier communication mode to the transmission power limit of the sender is lower than a threshold; If yes, data frames are sent simultaneously based on dual-mode communication; If not, data frames are sent separately based on dual-mode communication in different time periods. Specifically, in dual-mode communication, when there is a concurrent demand, the transmission power level of the wireless communication mode and the transmission power level of the power line broadband carrier communication mode can be converted into the proportion of the transmission power limit of the node according to the transmission power level of the wireless communication mode of the node and the transmission power level of the power line broadband carrier communication mode. If the sum of the proportion of the transmission power level of the wireless communication mode to the transmission power limit of the sender and the proportion of the transmission power level of the power line broadband carrier communication mode to the transmission power limit of the sender is lower than the threshold, that is, lower than 1, data frames are sent simultaneously based on the dual-mode communication mode. If the sum of the proportion of the transmission power level of the wireless communication mode to the transmission power limit of the sender and the proportion of the transmission power level of the power line broadband carrier communication mode to the transmission power limit of the sender is higher than the threshold, that is, higher than 1, data frames are sent separately in different time periods. In this case, it is generally recommended that the power line broadband carrier communication mode be sent first. This method can ensure the quality of data transmission and reduce operating energy consumption.

[0027] More specifically, the method of this embodiment can be applied to an Internet of Things communication system, and it is only necessary to process each node according to the above-mentioned sender and receiver operation procedures. The method of this embodiment is also applicable to wireless communication mode transmission power control or power line broadband carrier communication transmission power control. The only difference is that the initial value of the transmission power level, the receiving performance evaluation threshold value and the power level difference or the receiving performance level difference may be different. The actual communication effects of the two communication modes can be statistically analyzed and calculated.

[0028] Embodiment 2: like Figure 2 As shown, a method for automatic control of transmission power applied to dual-mode communication is applied to a receiving side, comprising: S21, setting a receiving control threshold value and a plurality of receiving performance levels, wherein a receiving performance level difference is set between two adjacent receiving performance levels; S22, receiving and interpreting the data frame sent by the sender according to the set initial transmission power level, and determining whether the receiving node is the target address of the data frame; S23, if yes, then record the source address of the data frame, determine the received signal quality mark according to the received signal quality of the data frame and the receiving control threshold value, and send a receipt data frame including the received signal quality mark to the sender, so that the sender can receive and interpret the receipt data frame, and adjust the initial transmission power level of the next frame of data frame sent to the receiver according to the received signal quality mark. Specifically, the receiver can set multiple receiving performance levels according to demand, and the receiving performance levels can be selected as the first level, the second level, the third level and the fourth level. There is a receiving performance level difference between each two adjacent receiving performance levels, and the receiving performance level difference can be selected as 3 fourth level second level. According to the communication rate, the transmission performance of the communication unit and the statistical analysis of the actual signal reception situation, determine the appropriate receiving control threshold value, such as -90 fourth level second level m. The receiver receives and interprets the data frame sent by the sender, and determines whether this node is the target address of the data frame. If this node is the target address of the data frame, the source address of the data frame is recorded, and the received signal quality mark is determined according to the received signal quality of the data frame and the receiving control threshold value, and a receipt data frame is sent to the sender, so that the sender can control and adjust the initial transmission power level of the next data frame according to the receipt data frame. If this node is not the target address of the data frame, the receiver does not further process the received data frame. Each time the receiver receives a data frame, it determines whether the receiver's node is the target address of the data frame. If so, the source address of the data frame is recorded, and the received signal quality mark is determined according to the received signal quality of each received data frame and the receiving control threshold value, and the determined received signal quality mark is sent back to the sender so that the sender can control the transmission power level according to the receipt data frame, improve the accuracy of power analysis, and reduce operating energy consumption.

[0029] As an optional implementation, the receiving performance level includes a first level, a second level, a third level and a fourth level, wherein the first level indicates that the quality of the received signal is less than the minimum value of the receiving threshold range, the second level and the third level both indicate that the quality of the received signal is within the receiving threshold range, and the fourth level indicates that the quality of the received signal is greater than the maximum value of the receiving threshold range. Specifically, the receiving threshold range is a range of values ​​from a value less than the receiving control threshold value by a receiving performance level difference to a value greater than the receiving control threshold value by a receiving performance level difference, that is, the minimum value of the receiving threshold range is a value less than the receiving control threshold value by a receiving performance level difference, and the maximum value of the receiving threshold range is a value greater than the receiving control threshold value by a receiving performance level difference. If the quality of the received signal is less than the minimum value of the receiving threshold range, it means that the receiving performance is weak, if the quality of the received signal is within the receiving threshold range, it means that the receiving performance is normal, and if the quality of the received signal is greater than the maximum value of the receiving threshold range, it means that the receiving performance is strong. The receiving party stipulates that when the received signal quality of the received data frame is greater than the receiving control threshold value and is less than one receiving performance level difference, the received signal quality is within the receiving threshold range, and the receiving performance level of the received data frame is recorded as the third level; when the received signal quality of the received data frame is greater than the receiving control threshold value and exceeds one receiving performance level difference, the received signal quality is greater than the maximum value of the receiving threshold range, and the receiving performance level of the received data frame is recorded as the fourth level; when the received signal quality of the received data frame is less than the receiving control threshold value and is less than one receiving performance level difference, the received signal quality is within the receiving threshold range, and the receiving performance level of the received data frame is recorded as the second level; when the received signal quality of the received data frame is less than the receiving control threshold value and exceeds one receiving performance level difference, the received signal quality is less than the minimum value of the receiving threshold range, and the receiving performance level of the received data frame is recorded as the first level.

[0030] As an optional implementation manner, determining a received signal quality mark according to a received signal quality of a data frame and a receiving control threshold value includes: Comparing the received signal quality with the receiving control threshold value; When the received signal quality is less than the receiving control threshold value and the difference between the received signal quality and the receiving control threshold value is at or above a receiving performance level difference value, the received signal quality is marked as the first level; When the received signal quality is less than the receiving control threshold value and the difference between the received signal quality and the receiving control threshold value is less than a receiving performance level difference value, marking the received signal quality as the second level; When the received signal quality is greater than the receiving control threshold value and the difference between the received signal quality and the receiving control threshold value is less than a receiving performance level difference value, marking the received signal quality as the third level; When the received signal quality is greater than the receiving control threshold value and the difference between the received signal quality and the receiving control threshold value is at or above a receiving performance level difference, the received signal quality is marked as the fourth level. Specifically, when the receiving party's node is the target address of the data frame, the receiving party determines and records the received signal quality mark according to the received signal quality of the data frame and the receiving control threshold value set by the receiving party. The determined rule is as follows: the received signal quality of the received data frame is less than the receiving control threshold value and the difference between the received signal quality and the receiving control threshold value is below a receiving performance level difference, and the received signal quality mark is recorded as the first level. The received signal quality of the received data frame is less than the receiving control threshold value and the difference between the received signal quality and the receiving control threshold value is below a receiving performance level difference, and the received signal quality mark is recorded as the second level. The received signal quality of the received data frame is greater than the receiving control threshold value and the difference between the received signal quality and the receiving control threshold value is below a receiving performance level difference, and the received signal quality mark is recorded as the third level. If the reception signal quality of the received data frame is greater than the reception control threshold value and the difference between the reception signal quality and the reception control threshold value is at or above one reception performance level difference value, the reception signal quality mark is recorded as the fourth level.

[0031] Embodiment three: like Figure 3 As shown, a device for automatic control of transmission power of dual-mode communication includes: The sender is used to send a data frame to the receiver according to the initial transmission power level, so that the receiver can interpret the data frame, determine whether the node of the receiver is the target address of the data frame, and if so, record the source address of the data frame, determine the reception signal quality mark according to the reception signal quality of the data frame and the reception control threshold value, and send a receipt data frame including the reception signal quality mark to the sender; receive and interpret the receipt data frame, and adjust the initial transmission power level of the next data frame sent to the receiver according to the reception signal quality mark. The receiver is used to receive and interpret the data frame sent by the sender according to the set initial transmission power level, determine whether the node of the receiver is the target address of the data frame; if so, record the source address of the data frame, determine the reception signal quality mark according to the reception signal quality of the data frame and the reception control threshold value, and send a receipt data frame including the reception signal quality mark to the sender, so that the sender can receive and interpret the receipt data frame, and adjust the initial transmission power level of the next data frame sent to the receiver according to the reception signal quality mark.

[0032] Specifically, the sender and the receiver are connected in communication, and the communication mode is dual-mode communication, namely, wireless communication mode and power line broadband carrier communication mode. The sender is a node, and the receiver is a node or multiple nodes. The method of the present application can be used for automatic control of transmission power between one node and another node, or for automatic control of transmission power between one node and multiple nodes. The data signal transmitted between one node and another node must include a determined source address of the sender and a destination address of the receiver, which can ensure that the communication is clear and single. In the communication between one node and multiple nodes, it is only necessary for the sender to establish a record list of initial transmission power levels for multiple target addresses, and send data frames to the receiver according to the set initial transmission power levels for different target addresses, so that the receiver can interpret the data frames and determine whether the receiver's node is the target address of the data frame. If so, the source address of the data frame is recorded, and the reception signal quality mark is determined according to the reception signal quality of the data frame and the reception control threshold value, and a receipt data frame including the reception signal quality mark is sent to the sender; so that the sender can receive and interpret the receipt data frame, adjust the initial transmission power level of the next data frame sent to the receiver according to the reception signal quality mark, and set the initial transmission power level for different target addresses according to the record list of initial transmission power levels of multiple target addresses.

[0033] As an optional implementation, the sender includes a sending unit and a sending analysis and processing unit, and the receiver includes a receiving unit and a receiving analysis and processing unit. The sending unit is used to send a data frame to the receiver according to the initial sending power level. The sending analysis and processing unit is used to receive and interpret the receipt data frame, and adjust the initial sending power level of the next data frame sent to the receiver according to the received signal quality mark. The receiving unit is used to receive and interpret the data frame sent by the sender according to the set initial sending power level, determine whether the node of the receiver is the target address of the data frame, and if so, record the source address of the data frame. The receiving analysis and processing unit is used to determine the received signal quality mark according to the received signal quality of the data frame and the receiving control threshold value, and send a receipt data frame including the received signal quality mark to the sender, so that the sender receives and interprets the receipt data frame, and adjusts the initial sending power level of the next data frame sent to the receiver according to the received signal quality mark. Specifically, the sending unit is connected to the sending analysis and processing unit in communication, the sending unit is connected to the receiving unit in communication, and the receiving single end is connected to the receiving analysis and processing unit in communication. The sending unit sends a data frame to the receiving unit. After the receiving unit determines that the node is the target address of the data frame, it sends the data frame to the receiving analysis and processing unit, which determines the received signal quality mark and then sends the data analyzed by the receiving analysis and processing unit back to the sending unit. After the sending unit receives the receipt data frame, it transmits it to the sending analysis and processing unit, which interprets the receipt data frame to control the sending power level.
