The constrained input that described user interface carries out user is mutual, comprises button, keyboard, LED, screen and sound prompting device.
The described Big Dipper/GPS module carries out the positional information of this field communication terminal of timing acquisition, and shows according to user instruction.
The positional information that the Big Dipper/GPS module obtains by described storage module and the positional information come alternately from other field communication terminals, carry out analyzing stored according to unified form, and be presented on screen according to the instruction of microprocessor.
Compared with prior art, the present invention has the following advantages:
1, compared with the scheme of integrated satellite communication terminal, the volume of terminal can be reduced, alleviate the weight of terminal, effectively can reduce power consumption, add battery standby time, search and rescue team member can be made like this to carry and more search and rescue equipment, add the search and rescue time.
2, compared with simple GPS intercom, each terminal not only can obtain oneself positional information, can also obtain the positional information of neighbouring terminal, and communication command vehicle can obtain the positional information analyzing and processing of all terminals and display in time.
3, compared with common wireless communications or principal and subordinate's intercom mode, the actual problem solving terminal location information transfer of data, so just can expand the coverage of search and rescue system greatly.
4, communication command vehicle can search and rescue the distribution situation of team member according to scene, deployment and the self-position of strength are searched and rescued in timely adjustment, and effective location tracking is carried out to search and rescue team member, reduce the possibility of searching and rescuing team member and meeting accident, because communication command vehicle adopts mobile unit, transmitting power can be adjusted to expand the coverage area, to the unidirectional transmission dependent instruction of each terminal, so just can improve field greatly and comprehensively search and rescue ability.
