Specific embodiment
Below in conjunction with schematic diagram to the maritime personal alarm and search and rescue system of the invention based on Beidou RDSS technology
It is described in more detail, which show the preferred embodiment of the present invention, it should be appreciated that those skilled in the art can modify
Invention described herein, and still realize advantageous effects of the invention.Therefore, following description should be understood as ability
Field technique personnel's is widely known, and is not intended as limitation of the present invention.
As shown in Figure 1, a kind of maritime personal alarm based on Beidou RDSS technology, including structure division and circuit portion
Point；Structure division is waterproof case, and circuit part is enclosed in the waterproof case；Circuit part includes Beidou RDSS module 5, electricity
Stream management module, electronic switch 3, MCU1, battery pack 2 and touching water induction device 4；
Battery pack 2 is electrically connected electronic switch 3 and MCU1；Battery pack 2 is powered to MCU1 and current management block；The letter of MCU1
Number input terminal connection touching water induction device 4；The signal output end of MCU1 connects current management block；The signal output end and electricity of MCU1
Electronic switch 3 is set between stream management module；MCU1 is received and feedback signal is to Beidou RDSS module 5；5 electricity of Beidou RDSS module
Connect the output end of current management block；Beidou RDSS module 5 and PERCOM peripheral communication.When touching 4 signal communication MCU1 of water induction device,
MCU1 signal communication electronic switch 3.Further, Beidou RDSS module 5 passes through receiving antenna 14 and transmitting antenna 13 and rescue
Base station communication.The alarm is not necessarily to power switch, can work when guaranteeing overboard in danger, realize the automatic alarm of real meaning,
It could work after being also switched on rather than general alarm terminal.Specifically, passing through the alarm when the alarm falls into the water
On touching water sensor detect the alarm be overboard state after, automatically turn on internal alarm circuit, the alarm is by low
Power-consumption standby state enters alarm condition.In the present embodiment, touching water sensor, which is used exclusively for perception detection alarm terminal, is
No water-immersed electronic device either a pair of electrodes.For this for electrode, after being immersed in the water, since water has one
Fixed electric conductivity will lead to this to being equivalent to an access resistance between electrode in this way, to formed between electrode at this
Pressure difference simultaneously generates electric current, triggers warning circuit.
In the present embodiment, which has the advantages that low-power consumption: current management block includes storage capacitor 6, power amplifier

In order to realize long-term standby mode, which is in low-power consumption mode state.Under low-power consumption mode, electronic switch 3 by
Low-power consumption MCU1 control disconnects the power supply that 9 circuits are driven to storage capacitor 6, base band power module 8, LED, Beidou RDSS module 5
To power off off position.After key 11, which has key 11 to press or touch water induction device 4, senses touching water, MCU1 is just by low-power consumption
State is transferred to normal operating conditions, then completes corresponding function operation.Through detecting, the work electricity of MCU1 in dormant state work
Stream is only 6.8uA.
In the present embodiment, which can export the function of high current moment.Specifically, battery pack 2 passes through electronic cutting
Not instead of directly amplifier power supply module 7 is not powered after closing 3, centre have passed through storage capacitor 6, the technology effect of this design
Fruit is the peak power output that 5 instantaneous transmission signal of Beidou RDSS module can be improved.If the not capacitor, Beidou RDSS module
5 peak power output is < 5dBW, and can increase to 10dBW output power after having storage capacitor 6.This is because the storage
The supply current that Beidou RDSS module 5 instantaneously works can be enhanced in energy capacitor 6, and is directly powered by battery and be difficult to realize above-mentioned mesh
's.Therefore, the present invention in Beidou RDSS module 5 emit signal have the advantages that in short-term, it is superpower.The alarm falls into the water
Afterwards, water transmission loss or the influence that other sundries stop be can reduce.Further, storage capacitor 6 is electrolytic capacitor, electrolysis
The model EGPA500ELL182MU40S of capacitor.
In addition, alarm can be continuously tracked in the alarm.Due to after man overboard may with the flowing of dampening dirty bit
Set, in order to balance be repeated several times alarm can gradually the electricity of consumption alarm terminal, search and rescue difficulty it is larger, search and rescue the time it is longer
In the case of, if the frequency of repetition of alarms is excessive, by problem depleted quickly, MCU1 can be set the electric energy of alarm terminal
Be set to: repetition of alarms is once to be alarmed for every 1 minute within overboard 1 hour, is every after the overboard time is greater than 1 hour
It carries out once within 15 minutes, and repetition of alarms updates the current location information and temporal information of alarm terminal every time.
It in the present embodiment, further comprise alarm drive circuit and warning lamp；Alarm drive circuit is electrically connected warning lamp；
Start-up circuit of alarming is electrically connected electronic switch 3.Wherein, alarm drive circuit is LED driving 9, and warning lamp is LED light 10, and LED drives
Dynamic 9 pairs of LED light 10 driving power supply.
It in the present embodiment, further comprise key 11 and working station indicator 12；Key 11 and working status indication
Lamp 12 is connect with MCU1 signal respectively, i.e. MCU1 receives the input signal from key 11, and control working station indicator 12 connects
The output signal from MCU1 is received to indicate different working conditions.Further, key 11 includes self-test key 11 and power supply
Electric power detection key 11.
It in the present embodiment, further comprise LDO；The input terminal and output end of LDO is electrically connected 2 He of battery pack
MCU1, i.e. battery pack 2 are powered by low-power consumption LDO (low pressure difference linear voltage regulator) Xiang Suoshu low-power consumption MCU1.
As shown in Fig. 2, the present embodiment also proposed it is a kind of using the maritime personal alarm based on Beidou RDSS technology
Search and rescue system, further include central station 15, search and rescue monitoring center 18, rescue center 16 and information distribution center 17；Search and rescue monitoring
Center 18, rescue center 16 and information distribution center 17 are connect with 15 signal of central station；Central station 15 and Beidou RDSS module 5 are logical
Letter.The alarm at least can be within the scope of China and surrounding countries using Beidou RDSS module 5, and realization is not limited by geographical location
Any region alarm of system；And rescue is issued from helping a variety of rescue center 16 of the central station 15 near the alarm position
Request, is sued and laboured by these rescue strength tissues, then can be improved the timeliness of rescue.
To sum up, the maritime personal alarm and search and rescue system provided in an embodiment of the present invention based on Beidou RDSS technology
