Connected system for outdoor groups

Abstract

The present invention is an interconnection system for outdoor activity groups. The interconnection system includes a plurality of interconnection devices. The interconnection devices can be used by each member of the outdoor activity group. Each interconnection device does not need external Internet or communication The device can use the RF signal transmission module to receive and transmit data packets with local identifiers, local location information and other interconnected device location information in the public open frequency band, so that each interconnected device has the functions of active transmission and relay transmission , so that each member of the outdoor activity group can be used as a relay station to extend the communication distance of the whole group without limit, and overcome the problem of losing contact between members because they are too far away to receive signals. It is especially suitable for use in Group activities such as outdoor mountaineering, expedition or motorcade can effectively improve the safety of outdoor activities.

Description

technical field [0001] The present invention is an interconnection system for outdoor activity groups. The interconnection system includes multiple interconnection devices. The technical content aims to use RF signals in the public open frequency band to transmit and relay transmission without the need for external Internet or communication devices. The data packet contains the positioning information of the local machine and each interconnected device, so that each member of the outdoor activity group can be used as a relay station to extend the communication distance of the entire group without limit. Background technique [0002] In recent years, with the popularity of outdoor leisure, exploration, and tourism, coupled with the development of the Internet and social networking sites, enthusiasts who love outdoor activities often organize outdoor activity groups with a large number of members, such as mountaineering teams, expedition teams, bicycle teams, and motorcycle tea...

AI Technical Summary

Problems solved by technology

[0009] Although the above method can more closely grasp the status of each member, the equipment cost, equipment weight and power demand required by the communication device in this topology network are relatively high, which is not conducive to activities such as mountaineering where the team is arranged roughly in a straight line one by one.

In addition, according to the existing technology, the wireless communication modules (such as WIFI or Bluetooth) required to form an independent topological network have the longest interconnection distance of only a few hundred meters, which is not suitable for communication between members. Mountaineering teams or convoys with long activity distances that may be as long as tens of kilometers

[0010] In fact, traditional walkie-talkies that use RF signals in public open frequency bands to broadcast have a transmission distance that is much longer than the transmission distance between the above-mentioned communication devices, and do not need the Internet to transmit information. However, its disadvantage is still that the distance is not far enough, and it is impossible to locate members
