Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, the safety positioning network based on mutual detection and mutual trust of nodes includes a plurality of positioning nodes (i.e., ground nodes in the graph) and at least one mobile node, where the positioning nodes and the mobile node both have a distance measurement capability, an information transmission capability, and a position calculation capability, and a distance measurement module, an information transmission module, and a position calculation module are correspondingly arranged, and the specific principle refers to the prior art.
Any positioning node can be detected by at least one adjacent positioning node, the positioning node with the mutual detection condition periodically measures distance information between the positioning node and the adjacent positioning node and caches the measurement information, and when the positioning node receives a ranging communication request of the mobile node, the latest periodic measurement result is fed back to the mobile node.
The periodicity determination takes into account the following factors:
1) Since the confidence detection ranging communication also occupies the communication channel, the ranging communication used for confidence detection per unit time cannot exceed: total ranging capability- (number of mobile nodes x number of fixed nodes (local range));
2) Dividing the distance measurement communication number of the confidence detection of the total unit by the number of the confidence detection in the local range, and calculating the distance measurement communication number into integral time which is the minimum value of the period;
3) The maximum value of the period is an empirical value determined empirically.

The mobile node is provided with a confidence detection module for carrying out confidence detection on the positioning node, the mobile node carries out confidence detection on the positioning node, and the mobile node uses the node to participate in position calculation and carries out position updating only after the positioning node passes the confidence detection.
The confidence detection comprises the following contents:
a) Verifying the identity information of the ground nodes according to the prefabricated electronic map, wherein only the nodes recorded in the prefabricated electronic map are legal nodes;
b) Checking the positions among the positioning nodes according to the prefabricated electronic map, and acquiring the node only when other ground nodes detect the position of the node and the acquired distance interval is consistent with the record of the prefabricated electronic map;
c) Setting a confidence interval for a currently measured distance value by using a historical memory position and a mobile displacement of the mobile node and combining with the information of the prefabricated electronic map, judging that the distance measurement is abnormal if the measured distance exceeds the confidence interval, and not collecting the node when the position is calculated.
It is to be understood that the confidence measure may include other things based on the above.
