Technical Field
The invention relates to the technical field of communication, in particular to an iridium satellite and radio dual-mode communication mode for an ARGO buoy/glider.
Background
In recent years, iridium communication has been widely used in ocean monitoring and detecting platforms due to its significant characteristics of long communication distance, wide coverage area, high system reliability, low data error rate, etc. However, iridium communication also has the disadvantages of high data communication cost, incapability of being used for indoor test and the like. There are two ways for iridium data transmission: the difference between dial-up communication and SBD communication lies in real-time performance, Iridium dial-up communication is real-time data transmission, Iridium SBD communication is that data is stored in an Iridium gateway firstly, and a shore station actively goes to the gateway to inquire and read the data. The iridium dialing communication has the advantages that the data transmission rate is high, the real-time performance is good, the influence of satellite signal fluctuation is large, and a communication link is easy to break when the signal is unstable, so that the communication efficiency is reduced; the iridium SBD communication is less influenced by satellite signal fluctuation, can carry out data transmission when the signal is poor, and has the defect of poor real-time performance.
Radio communication is widely used in short-distance communication because of its advantages of stability, reliability, high speed, low delay and low communication cost, but it has the disadvantages of short communication distance and low communication security.
In the actual research and development process of the ARGO buoy/glider, near-distance debugging and long-time sailing test in the open sea are generally needed, so that an iridium communication and a radio communication are combined to form a dual-mode communication mode, the defects of the two communication modes can be overcome, and the flexibility degree of the system is increased. In addition, according to the strength of satellite signals in a working environment, the size of transmitted data volume and the real-time requirement, two communication modes of iridium dialing + radio and iridium SBD + radio can be adopted, and the actual communication requirement is met.

The iridium and radio dual-mode communication mode for the ARGO buoy/glider is characterized in that two working modes of radio and iridium can be freely switched according to different working requirements.
Preferably, the two working modes of radio and iridium are freely switched, and the shore station freely selects a radio data transmission station communication mode or an iridium communication mode.

Preferably, the iridium and radio dual-mode communication mode for the ARGO buoy/glider comprises a data packet loss retransmission mechanism, and a unified data retransmission mechanism is adopted after data packet loss is caused by communication signal intensity fluctuation.
Preferably, the data retransmission mechanism is characterized in that after the all-in-one machine detects a data packet loss retransmission instruction, the data transmission mode is restarted, and the data packet is continuously requested from the central control system until all the data of the shore station are completely received.
Preferably, the iridium dial communication can automatically acquire the positioning information again and establish the communication link when the iridium dial communication link is disconnected, and the transmission is continued at the disconnected position of the data packet link.

Detailed Description
The following detailed description of specific embodiments of the invention will assist those skilled in the art in further understanding the invention, but is not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The hardware environment for implementing the invention comprises a hardware core control chip adopting STM32F 429. The control circuit uses a DTC143ZETL digital triode and an IRFHM9331 TRBF field effect transistor as a switch, and determines whether the radio data transmission module and the iridium module work or not by controlling the level through a GPIO port, so that the dual-mode control of radio data transmission radio station communication and iridium communication is realized. The communication level adopts RS232 standard, the level of the inner circuit of the singlechip is TTL level, and the level conversion circuit adopts MAX3232 chip as the level conversion chip.
The invention develops an iridium and radio dual-mode communication mode for an ARGO buoy/glider, wherein the iridium communication mode is iridium dialing or iridium SBD communication. Fig. 1 is a flow chart of iridium star dial-up communication/SBD communication and radio data transmission station dual-mode communication, and relates to a carrier center control system (central control system for short), a carrier communication positioning integrated machine (integrated machine for short), and a shore station system (shore station for short). And when the carrier central control system wakes up the all-in-one machine, the all-in-one machine respectively supplies power to the radio and the iridium module. And after the shore station determines to use a certain communication mode, the all-in-one machine automatically detects, confirms to connect the corresponding communication module and closes the other communication module.
Fig. 2 details the data transmission flow among the central control system, the all-in-one machine and the shore station. After the ARGO buoy/glider floats out of the water surface and meets the communication requirement, the central control system wakes up the integrated machine. And when the shore station determines to adopt a certain communication mode, the all-in-one machine automatically sends positioning information to the shore station and waits for the positioning information feedback of the shore station. And after receiving the positioning information feedback, transmitting the feedback to the central control system. The central control system sends the key information once every 2s, and the all-in-one machine sends the key information to the shore station until receiving the feedback of the shore station and sends the feedback to the central control system. And the central control system sends a data packet to the all-in-one machine after receiving the feedback, and the all-in-one machine automatically transmits the data until receiving the end packet. If the shore station system detects that data are lost, a data retransmission instruction is sent, the all-in-one machine conducts transparent transmission on the instruction, and the central control system conducts retransmission on the lost data. And after all the data are received, the shore station gives a control instruction to the carrier, and the all-in-one machine transmits the instruction. After all instructions are issued, the shore station issues a diving instruction to the carrier, and the central control system gives an all-in-one machine dormancy instruction to reduce power consumption. And the all-in-one machine completes one cycle of communication and waits for the next awakening of the central control system.
