However, the existing navigation system is usually a navigation system for a route, and usually guides a user to finish a navigation task after arriving at a destination, but for rural tourism, the navigation is often not satisfactory for the user. For tourists, they need, often, not only path navigation, but also end node navigation for destinations, for example: the tourists need to travel to a certain country, and after arriving at the country through the navigation system, the navigation system has no subsequent terminal service, and the tourists often need to guide the tourists to move to the correct direction by the outside because of arriving at a strange environment, and the existing navigation system is unwilling to develop the terminal navigation service aiming at the destination, and the reasons are summarized as the following points:

It should be noted that: in the embodiment, the newly-built map needs to be verified by a trusted certification authority, so that the safety of the data of the whole system is ensured.
As a further solution, the user updates the map of rural travel nodes in the network of service nodes by:
b1 user logs on account through front application program;
b2, verifying the account attribute, and if the account attribute is a service node user or a double-node user, carrying out the next step; if the account attribute is an application node, the existing map of the country tourism node cannot be updated;

b13, the whole network broadcasting is completed, and the update of the map of the country tourist nodes is completed.
It should be noted that: the concept of "user self-maintenance" proposed by the present embodiment includes two aspects: 1. the intelligent terminal equipment of each user provides a system carrier, and the normal operation of the whole system is ensured. 2. The map is drawn, newly built and updated by the user, namely, the local user can draw the map of the local or nearby tourist attractions of the country in a targeted manner, so that the problem that the existing navigation system cannot reach the terminal navigation due to overhigh maintenance cost is solved.
As a further solution, the service node network is further provided with a consensus reward mechanism, and achieves the whole network consensus through a network protocol; the consensus reward mechanism comprises an application node charging mechanism, a credible authentication mechanism reward mechanism, a map new reward mechanism and a map updating reward mechanism.
Specifically, the application node charging mechanism is used for charging service fees for each application node and storing the fees to the consensus ledger; the credible certification authority reward mechanism is used for paying maintenance cost to the credible certification authority and automatically transferring accounts to the credible certification authority at regular intervals through a common account book; the map new construction reward mechanism is used for providing reward for a service node of a new construction map, and if the application node uses the new construction map, service fees for the application node are automatically transferred to a wallet system of the service node according to a new reward proportion; the map updating reward mechanism is used for providing rewards for service nodes for updating the map, and if the application nodes use the updated map, service fees for the application nodes are automatically transferred to a wallet system of the service nodes according to the updated reward proportion.
It should be noted that: in the embodiment, the fee is collected and rewarded with each service node through the consensus rewarding mechanism, so that the enthusiasm of each service node is promoted, and the normal operation of the system is ensured.
As a further solution, the consensus reward mechanism further comprises a block-out reward mechanism, and the block-out reward mechanism adopts a dynamic balancing strategy and is performed through the following steps:
c1, each service node calculates the block probability, and the block probability formula is:
Figure BDA0003532102210000111
wherein j represents a service node number; qj represents the network response factor of the service node number j; m is the total number of the maps of the village tourism nodes stored by the service node number j; i is the number of a map of the tourist nodes in the village; ki represents the network request number of the application node to the i-number country tourism node map; ni represents the number of the service node j storing the number i of the country travel node maps, and ni is 1 by default; ni stores the number of the village tourism node map i for the whole network service node;
c2, each service node adjusts the map storage strategy of the village travel nodes, and takes out the storage strategy with the highest block probability to selectively store the village travel nodes;
c3 requesting the required map of tourist nodes in village by each application node;
c4 service node network according to application node request country tourism node map to screen service node, to obtain stored corresponding country tourism node map block list;
c5, carrying out probability random block output according to the block output probability of each service node in the block output list to obtain a block output service node;
c6 provides the application node with the corresponding country tourism node map;
c7, after the terminal positioning navigation is completed, the application node pays the service fee;
the C8 consensus award mechanism automatically transfers the application node payment service fee to the wallet system of the block-out service node according to the block-out award proportion.
It should be noted that: the embodiment achieves the purpose of adjusting the storage balance of the whole network by adopting a block-out reward mechanism of a dynamic balance strategy. As people know that some country tourist nodes are more vigorous, a plurality of service nodes are needed to store maps, and a plurality of tourist nodes are few, so that the tourists do not need to spend a large amount of storage resources and only need to store the maps by part of the service nodes. In addition, some scenic spots already have a plurality of service nodes for map storage, and some newly-built nodes only have a few service nodes for storage, so that dynamic balancing is required. Therefore, in the present embodiment, the whole dynamic equalization process is implemented by calculating the block probability through each node, and it is sought that the block probability is as high as possible, so that the dynamic adjustment part is biased to be stored, for example: scenic spots with abundant people but few storage nodes, new scenic spots with few storage nodes, and nodes with high request amount and less storage amount.
The network response factor refers to a comprehensive index formed by response time, delay, packet loss rate, and the like of the service node, and may be determined according to an actual situation, and therefore, details are not described herein.
As a further solution, the block node manages the map of rural travel nodes by:
d1, if there is map file through the new step of country tourism node map, save the map file to the existing block memory area, and use as the existing map file;
d2 if there is map file through the new update step of the node map of the country tourism, replace the existing map file, the original map file is preserved to the historical block memory area, upgrade the map file and preserve to the existing block memory area, and upgrade the record table of the modification;
d3 if the current map file can not be used normally, backtracking the map file in the history block storage area, and replacing it, and updating the modification record table.
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
