The invention will be further described by the description of embodiments with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a method for sharing television data according to a preferred embodiment of the present invention. The method comprises the following steps:
s10, obtaining shared data of the television, and generating a data index according to the shared data.
Specifically, the shared data is data which is issued by the television and shared to other televisions in the private chain of the television. That is, when shared data exists in the private television chain, a data index is generated according to the shared data so as to search the shared data according to the data index. The data index may be a hash value obtained by performing hash encryption on the shared data and a characteristic value of the shared data, which are used as the data index to be written into an intelligent television private chain of the distributed intelligent television according to a consensus mechanism. Furthermore, the private chain of televisions may include a plurality of distributed nodes, where each distributed node may be specifically configured with a plurality of televisions, or may be configured with a single television. Of course, each television can be added into the private television chain by applying, namely, the televisions are registered as distributed nodes in the private television chain, and after the televisions are successfully registered, the distributed nodes in the private television chain have functions of storing the private television chain, sharing data, submitting a shared data acquisition request and the like.
And S20, registering the data index in the private chain of the intelligent television according to a consensus mechanism based on the physical area and the time area, so that the intelligent televisions in the private chain of the intelligent television share the shared data.
Specifically, the consensus mechanism based on the geographic area and the time area calculates the contribution value of each geographic node according to the geographic area and the time area, and performs competition accounting in a manner of proving rights and interests by taking the contribution value as rights and interests, so that the shared data is accounted according to the consensus mechanism, so that the shared data is shared to other televisions in a private chain of televisions, and the shared data is shared. The accounting of the data index of the shared data according to the consensus mechanism is to determine a geographical node for accounting the data index of the shared data, and record the data index of the shared data in all intelligent televisions contained in a geographical group corresponding to the geographical node, so that each intelligent television in an intelligent television private chain can acquire the shared data through the intelligent televisions contained in the geographical group.
Meanwhile, in this embodiment, as shown in fig. 2, the data index is registered in the private tv chain according to a consensus mechanism based on a physical area and a time area, so that the televisions in the private tv chain share the shared data:
s21, grouping the intelligent televisions contained in the intelligent television private chain according to the geographic region to obtain a plurality of geographic groupings, and taking each geographic grouping as one geographic node of the intelligent television private chain;
s22, grouping the intelligent televisions contained in the private chain of the intelligent television according to the time region to obtain a plurality of time groups, and combining all the time groups obtained by division to obtain a time region chain, wherein each time group is a node of the time region chain;
s23, determining contribution values of all the geographic nodes according to the time area chain, and determining the geographic nodes corresponding to the data index by taking the contribution values as benefits and using a mode of proving the benefits;
and S24, recording the data index in each intelligent television contained in the geographic group corresponding to the geographic node, so that televisions in the private chain of the intelligent televisions share the shared data.
Specifically, in the step S21, the geographical area is a geographical location area, that is, the geographical location where the smart tv is located is taken as a division basis. Here, the administrative area of the geographical area is taken as the division basis. The administrative region may be saved as a unit, and the foreign region may be a state or a city. Of course, the administrative area may be determined according to the size of the blockchain, e.g., in units of countries, in units of streets, etc. Correspondingly, as shown in fig. 3, the grouping the smart televisions included in the private chain of the smart televisions according to the geographical areas to obtain a plurality of geographical groupings, and taking each geographical grouping as a geographical node of the private chain of the smart televisions specifically includes:
s211, acquiring the geographic position of each intelligent television contained in the private chain of the intelligent television, and determining the administrative region of each intelligent television according to the geographic position;
s212, grouping the intelligent televisions contained in the private intelligent television chains by taking the administrative areas as division basis so as to group the geographies, and taking each geography group as one geography node of the private intelligent television chains.
Specifically, the geographical grouping comprises at least one smart television, all the smart televisions contained in the geographical grouping jointly adopt one geographical node for accounting, all the smart televisions in the geographical node serve as open workers, and when the geographical node digs tokens, the geographical node distributes the tokens according to the online time and performance of the open workers of the smart televisions. That is, after the geographical node obtains the accounting right, the geographical node obtains the token corresponding to the accounting right, and distributes the token to each smart television according to the online time and performance of each smart television contained in the token. The performance is the performance of the intelligent television and can be obtained by calling a configuration table of the intelligent television. In addition, each geographical node is provided with a punishment mechanism, so long as the condition that the data omission problem of normal billing of the node is avoided in administrative areas to which the geographical node belongs under the condition of preset time is guaranteed, and only one machine is in normal operation. That is, the punishment mechanism of the consensus mechanism is that under the preset time condition of the geographic area, when a smart television is in a working state in the geographic node, the geographic node counts normally. Wherein the preset time condition is preset, for example, 6 a.m. to 12 a.m. and so on.
Further, in the step S22, the time zone is determined based on a time zone, for example, a zone in beijing time, a zone in washington time, and the like. That is, the time zone includes 24 zones, and accordingly, 24 time packets may be divided according to the time zone. Correspondingly, as shown in fig. 4, the grouping the smart televisions included in the private chain of the smart televisions according to the time region to obtain a plurality of time groups, and combining all the time groups obtained by the division to obtain the time region chain specifically includes:
s221, obtaining the geographic position of each intelligent television contained in the private chain of the intelligent television, and determining the time zone area of each intelligent television according to the geographic position;
s222, grouping all intelligent televisions contained in the private chain of the intelligent televisions by taking the time zone area as a division basis so as to enable a plurality of time groups, and combining all time groups obtained by division to obtain the time zone chain.
Specifically, the geographical location determines that a time zone area in which each smart television is located is a time zone in which the geographical location is obtained, and the time zone is set as the time zone area in which the smart television is located. For example, the geographical location of the smart tv is beijing, and the time zone corresponding to beijing is beijing time zone, and then the time zone area in which the smart tv is located is beijing time zone area. In addition, the time grouping is to divide the blocks according to the time zone and the time zone, so as to obtain the area of the same time zone of the intelligent televisions contained in each block. That is, dividing blocks by the time zone area can obtain 24 time groups.
Further, in the step S23, the contribution value of each geographical node is determined according to the contribution value of each smart tv included in each geographical node, and the contribution value is a workload proof of each geographical node. That is, the workload certification is taken as the equity of the equity certification, so that the billing right is determined in combination with the equity certification. Accordingly, as shown in fig. 5, the determining the contribution value of each geographical node according to the time domain chain, and performing the competitive accounting by using the contribution value as the benefit and the proof of the benefit specifically includes:
s231, calculating contribution values of all intelligent televisions according to the time region chain when the intelligent television private links receive the index data;
s232, determining contribution values of all the geographic nodes according to contribution values of all the intelligent televisions contained in the geographic groups corresponding to the geographic nodes, and determining the geographic nodes corresponding to the data indexes by taking the contribution values as benefits and using a mode of proving the benefits.
Specifically, the hash algorithm of the contribution value of each smart television is an effective online weighting value TW of an effective T-time area chain in which nodes in the time area chain of the contribution workload PW of the smart television are online simultaneously. The validity is valid for 1, invalid for 0, and the online weighting value is proportional to the number of simultaneous online nodes in the time-zone chain. I.e. the greater the number of simultaneous online nodes, the greater the weighting value.
