As shown in figure 4, untethered alarm float working principle of the invention is as follows:
(1) carrying platform state information updating state
After buoy is installed in place, buoy circuit is connected by watertight connector 7 with carrying platform master control system cable, master control
System cable is made of power supply line and RS485 communication line.At this point, buoy circuit provides power supply by carrying platform.
Carrying platform master control system every 1 minute (can software setting, not only guaranteed that state updated in real time, but also will not refresh
Make the reduction of buoy circuit lifetime more) buoy circuit to is sent carrying platform status information by RS485 interface, receive information
Afterwards, itself storage system is written in status information by buoy circuit, and sends the notice carrying platform master control of " having been written into " status information
System.If master control system does not receive " having been written into " response in 60s (can software setting), carrying platform master control system will be sent out
It alarms out.
(2) Beidou positions and transmits state
After carrying platform accident, master control system controls release device and buoy is released into water, at this point, buoy circuit touching water is opened
Conducting is closed, power input is converted to buoy battery 6 and powered by power management module 503, and starts Beidou positioning calling module
507, it is established immediately with the communication channel (searching star) of big-dipper satellite, obtains Beidou positioning position information, and by this and carrying platform
Status information etc. compiles short message form (RDSS service) by big-dipper satellite uplink communication links, at regular intervals before having an accident
It sends frequency and is sent to commanding in the rear center.
(3) circuit self-destruction
After commanding in the rear center obtains the crash alarm information short message of buoy transmission, there are two types of self-destruction sides for buoy circuit
Formula.The first is command centre to buoy transmission " self-destruction " instruction, and buoy circuit completes self-destruction；When alarming one is setting buoy
Between thresholding, once thresholding reaches, buoy is automatically performed self-destruction.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, it is not used to
The limitation present invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should all include
