The invention will be further explained by the description of the embodiments with reference to the drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a television data sharing method according to a preferred embodiment of the present invention. The method comprises the following steps:
and S10, acquiring the shared data of the television, and generating a data index according to the shared data.
Specifically, the shared data is data that is distributed by the television and is shared to other televisions in the private chain of the television. That is to say, when shared data exists in the television private chain, a data index is generated according to the shared data, so that the shared data can be conveniently searched according to the data index. The data index may be a hash value obtained by hash-encrypting the shared data and a characteristic value of the shared data, and the hash value and the characteristic value are used as the data index and written into an intelligent television private chain of the distributed intelligent television according to a consensus mechanism. In addition, the television private chain may include a plurality of distributed nodes, where each distributed node may specifically be configured by a plurality of televisions, or may be configured by a single television. Certainly, each television can be added into the television private chain by applying for, that is, the television is registered to become a distributed node in the television private chain, and after the registration is successful, the distributed node in the television private chain has the functions of storing the television private chain, sharing data, submitting a shared data acquisition request and the like.
And S20, registering the data index in the smart television private chain according to a consensus mechanism based on the physical region and the time region, so that the smart televisions in the smart television private chain share the shared data.
Specifically, the geographic area and time area based consensus mechanism calculates contribution values of the determined geographic nodes according to the geographic area and the time area, and performs competitive accounting in a way of proving rights and interests by using the contribution values as rights and interests, so as to account the shared data according to the consensus mechanism, so as to share the position of the shared data with other televisions in a television private chain, and further enable sharing of the shared data. The step of keeping accounts for the data indexes of the shared data according to the consensus mechanism is to determine the geographic node for keeping accounts for the data indexes of the shared data according to the consensus mechanism, and record the data indexes of the shared data in all the intelligent televisions included in the geographic group corresponding to the geographic node, so that each intelligent television in the private chain of the intelligent televisions can acquire the shared data through the intelligent televisions included in the geographic group.
Meanwhile, in this embodiment, as shown in fig. 2, the data index is registered in the television private chain according to a consensus mechanism based on a physical region and a time region, so that the televisions in the television private chain share the shared data:
s21, grouping the smart televisions included in the smart television private chain according to geographical areas to obtain a plurality of geographical groups, and taking each geographical group as a geographical node of the smart television private chain;
s22, grouping the smart televisions included in the smart television private chain according to time regions 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 the geographic nodes according to the time region chain, taking the contribution values as rights and benefits, and determining the geographic nodes corresponding to the data index in a rights and benefits proving mode;
and S24, recording the data index in each intelligent television contained in the geographical group corresponding to the geographical node, so that the televisions in the private chain of the intelligent televisions share the shared data.
Specifically, in the step S21, the geographic area is a geographic location area, that is, the geographic location where the smart television is located serves as a dividing basis. The administrative region of the geographic region is used as the basis for the division. The administrative region may be province as a unit, and for foreign regions, state or city may be a unit. Of course, the administrative region may be determined according to the size of the block chain, for example, in units of countries, streets, and the like. Correspondingly, as shown in fig. 3, the grouping the smart televisions included in the smart television private chain according to geographic areas to obtain a plurality of geographic groups, and the using each geographic group as a geographic node of the smart television private chain specifically includes:
s211, acquiring the geographical 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 geographical position;
and S212, grouping the intelligent televisions included in the intelligent television private chain by taking the administrative region as a division basis so as to perform geographic grouping, and taking each geographic grouping as a geographic node of the intelligent television private chain.
Specifically, the geographical group comprises at least one intelligent television, all the intelligent televisions in the geographical group adopt one geographical node for billing, all the intelligent televisions in the geographical node are used as absenteeism, and when the geographical node digs the token, the geographical node distributes the token according to the online time and performance of the absenteeism of the intelligent televisions. That is, after the accounting right is obtained for each local administrative node, the geographic 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 included 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 geographic node is configured with a punishment mechanism, and as long as a machine is normally operated in an administrative region to which the geographic node belongs under the condition of preset time in the administrative region, the normal accounting of the node is ensured without data omission. That is to say, the punishment mechanism of the consensus mechanism is that the geographic node normally accounts when a smart television exists in the geographic node and is in a working state under the condition of preset time in the geographic region. Wherein the preset time condition is preset, for example, 6 am to 12 pm.
Further, in the step S22, the time zone is determined according to 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 groups can be divided according to the time zone. Correspondingly, as shown in fig. 4, the grouping the smart televisions included in the smart television private chain according to the time regions 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, acquiring the geographical 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 geographical position;
s222, grouping the intelligent televisions included in the intelligent television private chain by taking the time zone area as a dividing basis so as to group a plurality of time, and combining all the time groups obtained by dividing to obtain a time zone chain.
Specifically, the geographical location determines a time zone area where each smart television is located as a time zone corresponding to the acquired geographical location, and sets the time zone as the time zone area where the smart television is located. For example, the geographic location of the smart television is beijing, the time zone corresponding to beijing is a beijing time zone, and then the time zone area where the smart television is located is a beijing time zone area. In addition, the time grouping is divided into blocks according to the time zone, and the intelligent televisions contained in each block are located in the same time zone area. That is, dividing blocks by the time zone area can result in 24 time groupings.
Further, in the step S23, the contribution value of each geographic node is obtained according to the contribution value of each smart television included in each geographic node, and the contribution value is a workload certification of each geographic node. That is, the proof of the workload is taken as the right of the proof of the right, and the proof of the workload is combined with the proof of the right to determine the billing right. Correspondingly, as shown in fig. 5, the determining the contribution value of each geographic node according to the time domain chain, and performing competitive accounting in a manner of proving a right to the right by using the contribution value as the right to:
s231, when the private link of the intelligent television receives the index data, calculating the contribution value of each intelligent television according to the time region chain;
s232, determining the contribution values of all the geographic nodes according to the contribution values of all the intelligent televisions contained in the geographic groups corresponding to the geographic nodes, taking the contribution values as rights and determining the geographic nodes corresponding to the data indexes in a rights and interests proving mode.
Specifically, the hash algorithm of the contribution values of the smart televisions is the validity P of the enabled televisions, the contribution workload PW of the smart televisions, the validity T of the nodes in the time region chain, and the valid online weighted value TW of the time region chain. The validity is that 1 is effectively taken, 0 is inefficiently taken, and the online weighting value is in direct proportion to the number of simultaneous online nodes in the time domain chain. I.e. the greater the number of simultaneous online nodes, the greater the weighting value.
Based on the above method for sharing television data, the present invention further provides a computer-readable storage medium, where the computer-readable storage medium has one or more programs, and the one or more programs are executable by one or more processors to implement the steps of the method for sharing television data according to the above embodiment.
