Generally, the downlink data transmission device of the power internet of things based on the data hopping transmission link can be a power internet of things system.
The following description will be given by taking an electric power internet of things system as an example of a main body of an electric power internet of things system for executing a data hopping transmission link-based electric power internet of things downlink data transmission method. Referring to fig. 1, the method for transmitting downlink data in the power internet of things based on the data hopping transmission link specifically includes:
s110, a data management node receives test signals sent by all intelligent electric meters in current electric meter grouping, corresponding signal quality parameters are determined based on the test signals, one intelligent electric meter is selected from the electric meter grouping as a main node based on the signal quality parameters, data jump transmission links of all the intelligent electric meters in the electric meter grouping are constructed corresponding to the main node, the data jump transmission links are sent to all the corresponding intelligent electric meters in the electric meter grouping, corresponding session keys are configured for the main node, and the data jump transmission links identify corresponding downlink data jump transmission objects of all the intelligent electric meters in the electric meter grouping and are used for jump-transmitting downlink data received by the main node to the corresponding intelligent electric meters.
The electric power internet of things downlink data transmission method based on the data hopping transmission link aims at determining signal quality of signal communication between each intelligent ammeter grouped by the ammeters and the data management node through signal testing, further selecting a main node of the ammeters grouped according to the signal quality, generating a corresponding downlink data hopping transmission link and issuing the corresponding downlink data hopping transmission link to each intelligent ammeter. Each intelligent electric meter selects a jump transmission object to jump-transmit the downlink data according to the downlink data jump transmission link, so that high-quality transmission of the downlink data is guaranteed, and system service operation is optimized.
Specifically, referring to fig. 2, in the embodiment of the present application, the data management node 11 is configured to issue downlink data of each smart meter 12, so as to implement relevant service processing and operation of the electric power internet of things system. In the electric power Internet of things system, the intelligent electric meter system comprises a plurality of intelligent electric meters 12 and a data management node 11, wherein each intelligent electric meter is distributed at each position in the communication range of an Internet of things gateway. When different intelligent electric meters perform data interaction with the data management node, the signal quality is different under the influence of signal multipath fading. In order to optimize the downlink data transmission effect and reduce the influence of signal attenuation, for part of smart meters with relatively poor signal communication quality with the data management node, other smart meters can be selected as communication relays, and the communication relays are used for skipping downlink data to corresponding smart meters, so that better downlink data transmission performance is guaranteed. Moreover, considering that the distribution position of the smart electric meter may be relatively far, long-distance jump transmission of downlink data may affect the data transmission quality. Therefore, according to the embodiment of the application, the intelligent electric meters are grouped according to different region positions, and the intelligent electric meters are divided into a plurality of electric meter groups. And then, signal testing of each intelligent electric meter is carried out on the basis of electric meter grouping of different region positions. Referring to fig. 2, each smart meter 12 sends a test signal to the data management node 11, performs a signal test, and determines a master node of a current meter group based on a signal test result.
The signal quality parameters corresponding to the intelligent electric meters are determined according to the test signals, and then the intelligent electric meter with the largest signal quality parameter can be selected from the electric meter groups as a main node based on the signal quality parameters. In particular, the signal quality parameter value of the test signal is determined by the corresponding signal received power, signal received strength, channel instantaneous quality value and/or interference signal strength. Wherein the channel instantaneous quality value represents the channel quality, channel matrix feedback, signal response, and/or interference information for the corresponding signal receiving antenna. And measuring the various types of parameters through the corresponding test signals and the antenna parameters. Further, in order to quantize the signal quality parameter, a calculation formula of the signal quality parameter is provided to quantize the signal quality of the test signal, and the calculation formula of the signal quality parameter is:
f＝ω1P+ω2d1+ω3h+ω4d2
where f is the signal quality parameter value, P is the signal received power, d1For signal received strength, h is the instantaneous quality value of the channel, d2For interfering signal strength, omega1，ω2，ω3And ω4The influence factors are determined according to actual tests and can be set according to the actual influence of each type of parameter on the signal quality parameter value. Based on the signal quality parameter calculation formula, the signal quality parameters of the test signals can be determined. It should be noted that, in practical applications, according to different signal quality evaluation criteria, a plurality of different manners may be selected to evaluate the signal quality parameters of each test signal, and a corresponding quantization formula is set accordingly. The above formula is only one calculation method for calculating the signal quality parameter in the embodiment of the present application, and various different measurement and calculation formulas may be selected according to actual measurement and calculation requirements, which is not described herein again.
And determining the signal quality parameters of the test signals of each intelligent ammeter based on the signal quality parameter calculation mode, and selecting the intelligent ammeter with the largest signal quality parameter as a main node of the current ammeter group based on the signal quality parameters. And further constructing a data jump transmission link corresponding to the main node, wherein the downlink data jump transmission object of each intelligent electric meter is selected according to the distance between each intelligent electric meter and the main node, and a corresponding data jump transmission link is constructed. And the main node is used as a starting point of the data jump transmission link and is used for receiving downlink data of the corresponding intelligent electric meter, which is issued by the data management node, and jumping and transmitting the downlink data to the corresponding intelligent electric meter according to the data jump transmission link. When a data jump transmission link is constructed, the data management node takes the rest intelligent electric meters in the electric meter group as subordinate nodes of the main node, and jump transmission objects of the intelligent electric meters are determined from near to far based on the distance between each subordinate node and the main node. It can be understood that if a node closest to a certain smart meter is a master node, the master node takes the smart meter as a skip transmission object; if the node closest to a certain intelligent electric meter is another intelligent electric meter and the other intelligent electric meter is closer to the main node, the other intelligent electric meter takes the intelligent electric meter as a jump transmission object. And each intelligent electric meter selects a jump transmission object according to the distance between the intelligent electric meter and the main node, and then the data jump transmission link is constructed. After the data jump transmission link is constructed, the data management node sends the data jump transmission link to each intelligent electric meter in the corresponding data jump transmission link so as to inform each intelligent electric meter in the current data jump transmission link to jump-transmit downlink data to the corresponding intelligent electric meter according to the jump transmission object indicated by the data jump transmission link. Based on the data hopping transmission link, when each intelligent electric meter performs downlink data hopping transmission, the hopping transmission object of the downlink data of each intelligent electric meter can be determined from the data hopping transmission link, and then the downlink data is hopped to the hopping transmission object, so that the downlink data of each intelligent electric meter is hopped step by step in the data hopping transmission link, and the downlink data can be hopped to the designated intelligent electric meter. The intelligent electric meter selects a downlink data skip transmission object nearby, downlink data are transmitted within a short communication distance, the influence of signal fading is reduced, the stability of data transmission is guaranteed, and the transmission quality of the downlink data is improved.
By referring to the above manner, the data jump transmission link of each electric meter group can be correspondingly constructed. In addition, the data management node further distributes session keys to the main nodes of each electricity meter group, the session keys obtained by each main node are different, and the security of downlink data transmission can be guaranteed by distributing the session keys to each main node.
In one embodiment, the data management node conducts signal testing of the electric meter grouping intelligent electric meters again every other testing period, and a new data jump transmission link is reconstructed based on a new signal testing result. Considering that the data transmission network is influenced by various factors, the data transmission quality of the data transmission network also changes in real time. In order to ensure the transmission quality of downlink data, it is necessary to ensure that good data transmission performance is maintained between the data management node and the master node in real time. Based on this, the embodiment of the application performs the periodic signal test of grouping each intelligent ammeter corresponding to the ammeter by setting the time period, and obtains the signal test result of each intelligent ammeter and the data management node by referring to the signal test mode of the data management node. Based on the new signal test results, it can be determined whether to perform a master node reselection. If the signal transmission quality of the original master node and the data management node is found to be optimal according to the signal test result, the master node does not need to be reselected, otherwise, the master node needs to be reselected. It can be understood that after the master node is determined again, a data hopping transmission link needs to be reconstructed corresponding to the distance between the new master node and each smart meter grouped currently for downlink data transmission, so that the stability of service transmission is guaranteed in real time.
In an embodiment, every other set session security management period, the data management node updates each session key to the corresponding master node. It can be understood that the difficulty of session key cracking can be increased by periodically updating the session key, and the situation that the downlink data is stolen and tampered because the session key is easily cracked is avoided. Therefore, the safety of downlink data transmission is improved, and the operation of the power internet of things is optimized.
And S120, allocating channel transmission resources for the corresponding main nodes based on the number of the intelligent electric meters grouped by the electric meters, and transmitting downlink data corresponding to the main nodes.
Further, after the construction of the data hopping transmission link of the electric meter packet is completed, the embodiment of the application further allocates the channel transmission resources corresponding to each master node. The channel transmission resource is used for the data management node to send downlink data to each main node. And setting bandwidth distribution weights corresponding to the intelligent electric meters according to the quantity of the intelligent electric meters grouped by the electric meters, and distributing channel transmission resources based on the bandwidth distribution weights. The electric meter groups with the large number of corresponding intelligent electric meters can distribute more channel transmission resources to the main node of the electric meter groups, and the electric meter groups with the small number of corresponding intelligent electric meters can distribute relatively less channel transmission resources to the main node of the electric meter groups. Through reasonable distribution of channel transmission resources, the situation that the electric meters with less network resource requirements occupy too much bandwidth in groups can be avoided, and the utilization rate of network resources is further improved.
In one embodiment, the downlink data volume of the electric meter group is counted based on the downlink data received by the main node in a set time period, and the channel transmission resource allocation weight of the main node is modified according to the downlink data volume. The data management node can determine the downlink data volume of each ammeter group by counting the downlink data issued to each main node within a set time period. The channel transmission resource distribution weight (namely, the bandwidth distribution weight) distributed before is modified according to the downlink data volume, so that the reasonable distribution of the channel transmission resource can be ensured in real time, and the utilization rate of the network resource is further improved.
S130, when the data management node transmits downlink data to the corresponding intelligent electric meters grouped by the electric meters, adding the identity identification of the corresponding intelligent electric meters in the downlink data, encrypting the downlink data by using the session key and transmitting the encrypted downlink data to the corresponding main nodes;
and S140, after receiving the downlink data, the corresponding master node decrypts the downlink data by using the session key, analyzes and obtains the identity of the downlink data, and hops the downlink data to the corresponding smart meter based on the corresponding data hopping link and the identity.
Referring to fig. 3, when the data management node 11 downloads the downlink data to one of the smart meters 12, the downlink data is transmitted to the master node corresponding to the meter group according to the meter group to which the smart meter 12 belongs. And when transmitting the downlink data, the session key is further used for encrypting the downlink data so as to ensure the security of downlink data transmission. In addition, in order to facilitate the downlink data to be jumped to, each smart meter corresponding to the data jump transmission link definitely jumpers the downlink data to which smart meter, the data management node adds the identity of the smart meter in the downlink data, so that each node in the data link definitely determines the receiving object of the downlink data.
Further, after the data management node sends the downlink data to the corresponding master node, the master node firstly decrypts the downlink data by using the session key issued by the data management node in advance, further analyzes and obtains the identity contained in the downlink data, and queries the data skip link according to the identity so as to determine to which skip object the current downlink data is skipped to. Similarly, after receiving the downlink data, the next node also queries the data skip transmission link based on the identity contained in the downlink data so as to skip the downlink data further to the corresponding skip transmission object, and so on until the downlink data is transmitted to the corresponding smart meter. It can be understood that the transmission quality of the downlink data can be ensured by uniformly receiving and skipping the downlink data by the master node, and the transmission quality of the downlink data can be further ensured by skipping the downlink data within the ammeter group step by step in a short distance, so that the operation processing of the system service is optimized.
In one embodiment, when the data management node detects that the corresponding master node fails, one smart meter is reselected from the meter grouping as a new master node based on the signal quality parameter, and the corresponding data hopping link is modified based on the new master node. It can be understood that when the original master node fails, an intelligent electric meter is selected from the electric meter group as the master node based on the previous signal test result again, and the data jump transmission link is further reconstructed based on the new master node by referring to the data link construction mode in the step S110, so that normal transmission of downlink data of the electric power internet of things system can be guaranteed, and the service operation effect of the electric power internet of things system is optimized.
In one embodiment, when the data management node detects that a new electric meter is accessed to the electric meter group, a superior jump transmission node of downlink data of the new electric meter is determined, and a corresponding data jump transmission link is modified. When the data management node detects that a new ammeter is accessed into a corresponding ammeter group, an intelligent ammeter is selected for the new ammeter as a superior jump transmission node of downlink data by referring to the data jump transmission link construction mode, and the downlink data of the new ammeter is jump transmitted to the new ammeter through the superior jump transmission node. And modifying the original data jump transmission link based on the selected superior jump transmission node, and adding the new electric meter to the corresponding position in the data jump transmission link. Similarly, the modified data hopping transmission link is not only sent to the new electric meter, but also to the intelligent electric meters grouped by the same electric meter, so that each intelligent electric meter can conveniently acquire the corresponding data hopping transmission relationship. It can be understood that the data hopping transmission link can adapt to each intelligent electric meter of the electric power internet of things system in real time by detecting the new access network of the intelligent electric meter and correspondingly modifying the data hopping transmission link, the data transmission quality of each intelligent electric meter is guaranteed, and the service operation of the internet of things system is optimized.
