Immersion sensor detects signal, is sent to control unit, and control unit starts above-mentioned alarm flow.In order to avoid at wave and
False alarm under the environment such as sleety weather, is also provided with depth transducer and delay circuit, reaches certain depth terminal is overboard
And after certain time, just can send alarm signal to control unit, startup alarm flow.The overboard degree of depth and persistent period
Can independently be set by user as required, when both are zero, it is achieved meet water and i.e. report to the police.
In order to extend the service life of this terminal and save the energy consumption of this terminal, this terminal also includes timing circuit, fixed
Time circuit be connected with control unit, continue after being used for controlling positioning and communicating device dormancy a period of time to search and rescue center send terminal
Positional information.This timing circuit so that control unit after receiving the feedback signal at search and rescue center by positioning and communicating
Device is in the dormancy of a period of time, after dormancy time passes, controls device and continues to control positioning and communicating device to search and rescue
Center sends alarm signal.When not receiving the feedback signal from the center of search and rescue, control unit sends the frequency of alarm signal
Rate is higher, and after receiving feedback signal, automatically reduces the frequency sending alarm signal, significantly reduce terminal energy
Consumption, extends time of fire alarming.When in time rescuing personnel and leave initial position because of a variety of causes, owing to terminal may proceed to send out to search and rescue center
Send positional information, the position of real-time tracking personnel to be rescued, such as rescue at sea, increase and search and rescue probability.Wherein dormancy time is permissible
Manually set by timing circuit.This terminal split type in the present embodiment, falls into water at the power control tying up to waist
Time middle, the positioning and communicating device being placed on head will not be affected by, it is ensured that the reliability of terminal.
Additionally, control unit includes microcontroller and perimeter interface circuit, wherein RNSS unit can be selected for UM220, RDSS
Device can be selected for CP0558, and microcontroller can be selected for ARM microprocessor.The present embodiment terminal uses chip-scale deviceization design,
There is volume advantage little, low in energy consumption, lightweight.Certainly, in terminal, each unit can also use the core of other suitable types
Sheet, does not do any restriction at this.
The present embodiment field emergency based on navigation system searches and rescues terminal, and after receiving alarm signal, power supply controls dress
Putting interior power module and start positioning and communicating device, then positioning and communicating device receives the B1 about terminal from navigation system
Frequency signal, then produces the current location information of terminal, by control unit control by RNSS unit in positioning and communicating device
Send to RDSS unit, received by navigation system via RDSS unit, be then forwarded to search and rescue center, when search and rescue center receives
After warning message, sending feedback signal, feedback signal is sent to positioning and communicating device by navigation system, and then by control unit
Processing, this terminal utilizes navigation system so that in desert, remote mountains, that the unfrequented place such as off-lying sea does not exist communication is blind
District, it is ensured that communicate smooth and easy, it is achieved search and rescue the advantage that scope is wide, the time is short, improve search efficiency；Warning message sends to searching and rescuing
