Abstract：Finding a central fishing ground is a matter of great concern in fishery production. Beidou ocean buoy can provide effective support for rapid fishing ground search. This research was based on Beidou satellite short message communication. Using object-oriented method to design terminal software, the data receiving and control for ocean buoy was realized. The sensor data decomposition package was used as a multi-frame method to solve the problem of limited data volume of Beidou short message. The terminal software received data through hash table management. Queues were used to manage messages and commands sent back. Multi thread was used to manage multiple buoys. The terminal software on buoy data receiving and control had passed five groups of data receiving and transmitting tests. The success rate of single frame data receiving and transmitting was 94.6%. The success rate of multi frame data receiving and transmitting was 90.5%. All 74 control commands were sent successfully. The buoy has the characteristics of miniaturization, low cost and long-term uninterrupted operation. It can be applied to data collection services such as fishery resources exploration and marine environment monitoring.
