Table 1 shows that the PLB we designed has more functions and higher
performance.
Conclusion: This letter improves the Personal Location
Beacon(PLB), designs and implements a prototype personal maritime
emergency radio beacon. The personal beacon used for at sea. Firstly,
the beacon automatically or manually activates the Beidou transmitter
and COSPAS transmitter to send distress signals not only to the global
rescue center, but also to send distress information to the Beidou
rescue organization, which alleviates the problem of insufficient COSPAS
satellite resources and increases the probability of rescue. Secondly,
the human vital signs information is added to upload, so that the search
and rescue organization can understand at any time. Thirdly, it
increases the BeiDou short message return information circuit, which
notifies the personal beacon to stop transmission when the information
of the marine accident is confirmed, saving battery power and extending
the working time of the personal beacon, which also increases the rescue
chance of the people in distress. Therefore, the design of the beacon
has more functions and higher performance, and has certain practical
significance in marine rescue.
