[0022] The utility model provides a buoy radiation monitoring system based on BeiDou-3, such as Figure 1-4 As shown, it includes multiple data collection devices, satellites and ground data transfer centers.

[0023] Among them, multiple data acquisition devices are dispersedly arranged in the detection sea area, and are used to perform radiation detection on the seawater in the detection sea area to obtain seawater radiation detection data, and upload the seawater radiation detection data to the ground data transfer center via satellite, so that the ground data transfer center forwards the seawater radiation detection data to the data processing center, and realizes remote monitoring of the seawater radiation in the detection sea area. Specifically, by arranging multiple data acquisition devices in the embodiment in the surrounding sea area of ​​the nuclear power plant, it is possible to detect the seawater radiation in the sea area around the nuclear power plant, timely detect the operating status of the nuclear power plant, and ensure the normal operation of the nuclear power plant and the safety of personnel.

[0024] Preferably, each data acquisition device includes a microcontroller chip, a positioning module, a detection sensor device, a satellite communication module and a power module. The power module is used to provide power supply for the entire data acquisition device. Since the data acquisition device is located in the ocean, it needs to be equipped with a separate power supply to ensure independent power supply.

[0025] The positioning module is used to locate the data acquisition device and obtain the location information of the data acquisition device. Normally, the detection area is relatively wide, so this embodiment sets a positioning module in the data acquisition device to locate the data acquisition device in real time while collecting data.

[0026] The detection sensor device is used to perform radiation detection on the seawater at the location of the data acquisition device to obtain seawater radiation detection data. Specifically, the type of the detection sensor device can be set according to actual needs.

[0027] The microcontroller chip is connected to the satellite communication through the satellite communication module, and then connected to the ground data transfer center. The utility model uses satellites to achieve data transmission and ensures the timeliness of data. Specifically, the satellite in this embodiment is BeiDou-3. The utility model uses the BeiDou network to achieve data transmission, which is not limited by network cables, and can achieve radiation detection in a larger range of sea areas, while ensuring the timeliness and accuracy of data transmission.

[0029] More preferably, since there is a certain distance between the slave device and the master device, in order to avoid the stability of data transmission between the slave device and the master device, the data acquisition device as the slave device in the utility model can be directly connected to the data acquisition device as the master device through communication, or can be indirectly connected to the data acquisition device as the master device through other data acquisition devices as slave devices. When sending seawater radiation detection data to the master device, the data acquisition device of each slave device can select a slave device that is closer to itself to forward the seawater radiation detection data. In addition, when the master device is abnormal, when the data analysis center determines that the master device is abnormal, it can send a configuration instruction to any data acquisition device in the slave device through a satellite to configure it as a master device, thereby ensuring the stable operation of the data acquisition device under normal working conditions. The utility model can send the seawater radiation detection data collected by the data acquisition device in a set area to the data analysis center through a satellite through the master and slave devices, thereby realizing the detection and analysis of seawater radiation in a set area.

[0031] The first-level boss 2 is hollow inside and is used to install the microcontroller chip, positioning module, satellite communication module and power module of the corresponding data acquisition device. The utility model sets the data acquisition device as a circular shell, so that the data acquisition device can be ensured to float on the sea level. More preferably, a floating assembly 5 is symmetrically arranged around the circular platform 1, and the floating assembly 5 can ensure the buoyancy and stability of the circular platform 1 on the sea level.

[0032] Preferably, a fixed bracket is provided on the top of the secondary boss 3, and a mounting platform 6 is provided on the top of the fixed bracket, and an indicator light 61 and a solar panel 62 are installed on the mounting platform 6.

At the same time, the power conversion module is electrically connected to the battery, the power management module, and the micro-control chip, which is used to convert the electric energy of the battery into the power supply of the micro-control chip.

[0034] The power management module is also used to convert the electric energy of the solar panel 62 into the power supply of the microcontroller chip. That is, part of the electric energy generated by the solar panel 62 is stored in the battery for backup, and the other part can be used by the microcontroller chip. When there is no sun or the solar power supply is insufficient, the battery power supply can be activated in time.
