Description

Technical Field

[0001] The utility model relates to the field of interconnection and communication, and more specifically to a portable front-address command device. Background Art

[0002] In field rescues, geological explorations, and military operations, the usual configuration is a set of walkie-talkies to solve communication problems among on-site members; and a satellite phone is configured for the team leader to maintain contact with the back-end command center. The problems brought by this are that the communication between the command center and the on-site team needs to be relayed manually by the team leader, which is not only inefficient but also prone to problems.

[0003] Currently, in the field of instant communication and command, in order to ensure stability and reduce the possibility of functional failures, conventional military or civilian devices often have relatively single functions and can only achieve point-to-point or point-to-group intercom communication. When more complex functions need to be completed, a single device alone cannot meet the requirements. At the same time, in case of an emergency, these devices may also become unusable due to power failure. Summary of the Invention
