Before introducing the method for transmitting meteorological data based on low-orbit satellite communication provided by this application, the background content involved in this application is first introduced.

The method, device and computer-readable storage medium for transmitting meteorological data based on low-orbit satellite communication provided by the present application can be applied to the terminal of a weather station, and used to introduce low-orbit satellite communication for the terminal of a weather station, so as to be free from ground communication. In the case of network constraints, the transmission of weather data can be completed with low power consumption.

In the method for transmitting meteorological data based on low-orbit satellite communication mentioned in this application, the execution subject may be a transmission device for meteorological data based on low-orbit satellite communication, or a device that integrates the transmission device for meteorological data based on low-orbit satellite communication. Weather station terminal. Wherein, the transmission device of meteorological data based on low-orbit satellite communication can be implemented by means of hardware or software, and the terminal of the meteorological station can be set by means of equipment clusters.

Next, the method for transmitting meteorological data based on low-orbit satellite communication provided by the present application will be introduced.

First, referring to FIG. 1, FIG. 1 shows a schematic flow chart of a method for transmitting meteorological data based on low-orbit satellite communication of the present application. The method for transmitting meteorological data based on low-orbit satellite communication provided by the present application may specifically include the following step:

Step S101, the meteorological station terminal collects meteorological data through the configured meteorological sensor;

It can be understood that after the low-orbit satellite communication is introduced for the meteorological data collection link at the end of the meteorological work in this application, since the communication can be flexibly and conveniently carried out to the sky, the equipment for performing the meteorological data collection work can get rid of the original The fixed deployment position of the equipment can be flexibly deployed in the field environment according to the collection requirements of meteorological data. As a new type of weather station terminal configuration, it breaks through the geographical use restrictions and expands the use scenarios.

The meteorological station terminal can be configured with corresponding meteorological sensors according to the preset meteorological data collection requirements, so that under the working control of the meteorological station terminal, the original meteorological data can be collected for subsequent meteorological work data. use.

As an example, the weather station terminal can include a weather sensor and a weather station control center. The weather station control center can be understood as a control device, which can control the meteorological data collection and execution of the weather sensor according to the pre-written control instructions. Meteorological data transmission work, in addition, it can also control the meteorological data collection work of the meteorological sensor and execute the meteorological data transmission work according to the received control instructions.

In practical applications, the weather sensors and the weather station control center are configured to be independent of each other, so that each weather sensor can be deployed in a specific environment on a larger scale.

The weather station control center includes hardware structures such as a Microcontroller Unit (MCU), a power module, a low-orbit satellite communication module, a memory, and even a positioning module (positioning module such as a GPS module) for the realization of a weather station terminal. It is used for work other than meteorological data collection of meteorological sensors.

The weather station control center, also known as the weather station body, is independently set up from the weather sensors outside the body.

Of course, in some application scenarios, the weather sensor can also be arranged on the weather station body.

As a practical implementation, in practical applications, the meteorological sensor may specifically include at least one of different types of meteorological sensors, such as wind speed sensor, wind direction sensor, rain sensor, air pressure sensor, temperature and humidity sensor, and light sensor.

For the connection between the weather sensor and the weather station body, in addition to the wired communication connection based on the data transmission line (for example, the wired communication method based on RS485, I2C, RS232 and other interfaces), preferably wireless communication connection can also be used.

Specifically, as another practical implementation method, a wireless communication connection method such as Bluetooth communication, Wi-Fi or LoRa and other different wireless communication connection methods can be used between the weather station terminal body and the weather sensor. It is more convenient to deploy meteorological sensors in space, and it can also overcome the inconvenient layout of wired communication lines in the specific environment of the site.

Specifically, the structural composition of the weather station terminal can also be understood with reference to a schematic structural diagram of the weather station terminal of the present application shown in FIG. 2 .

Step S102, the weather station terminal stores the weather data;

After the weather data is obtained through the weather sensor, the weather station terminal can store it locally first.

It can be understood that after the meteorological station terminal obtains the meteorological data, it is not sent out immediately. Considering the need to reduce power consumption, the meteorological data transmission work is carried out under the condition of the best low-orbit satellite communication quality. of.

Therefore, in each waiting time period, the meteorological data is stored first, which also has the effect of data aggregation, and the transmission of the meteorological data is carried out until the time point with the best low-orbit satellite communication quality is reached.

Step S103, when the meteorological station terminal detects that the low-orbit satellite is over the top, it transmits the meteorological data to the low-orbit satellite, and instructs the low-orbit satellite to forward the meteorological data to the data processing center through the low-orbit satellite communication system, so that the data processing center is based on the meteorological data. The data performs preset meteorological data processing work.

Specifically, this application configures the time point with the best low-orbit satellite communication quality as the time point when the low-orbit satellite passes overhead, that is to say, when the low-orbit satellite passes over the terminal of the weather station, the best low-orbit satellite communication quality is achieved. If the quality of orbit satellite communication is satisfied, the transmission of meteorological data can be carried out at this time.

It can be understood that a low-orbit satellite corresponds to a low-orbit satellite communication system, which completes the forwarding of relevant signals through a low-orbit satellite in the sky and a satellite ground station on the ground.

In this way, the meteorological data can be forwarded from the low-orbit satellite communication module at the terminal of the meteorological station to the satellite ground station on the ground through the low-orbit satellite in the sky, and then forwarded to the data processing center preset in the meteorological work. Complete the corresponding meteorological work.

It can be understood that compared with high-orbit satellite communication, low-orbit satellite communication can effectively reduce the demand for communication energy consumption, and thus prolong the service life of the terminal in practical applications, especially suitable for meteorological environment monitoring scenarios in areas without electricity and power grids.

Further, referring to a schematic diagram of a scenario of a method for transmitting meteorological data of the present application based on low-orbit satellite communication shown in FIG. 3 , after the meteorological data is processed by the meteorological work, the data processing result can be sent to the user side, To achieve the effect of meteorological staff viewing, public viewing of weather forecasts and other effects.

It can be seen from the embodiment shown in FIG. 1 that, for the transmission of meteorological data, the present application is equipped with a low-orbit satellite communication module on the terminal of the meteorological station, so that after the meteorological data is collected and stored, the low-orbit satellite is detected. When passing the top, the meteorological data can be transmitted to the low-orbit satellite, and the meteorological data can be forwarded to the data processing center through the low-orbit satellite communication system, so that the data processing center can perform the preset meteorological data processing work according to the meteorological data. The terminal of the meteorological station can communicate with the sky and transmit the meteorological data, which avoids the limitation of the ground communication network in the prior art. Secondly, the low-orbit satellite communication can bring lower energy consumption than the high-orbit satellite communication, so that the The transmission of meteorological data can be completed with low power consumption without being restricted by the ground communication network, and the collection of meteorological data can be better completed.

Further, in practical applications, different specific optimization schemes and adaptability schemes may also be configured.

As another practical implementation method, in order to further reduce the power consumption of the weather station terminal, a sleep mechanism can also be introduced, so that the related equipment of the weather station terminal can be in a sleep state when not performing preset work, greatly reducing the power consumption of the weather station terminal. Reduce power consumption of related equipment.

Exemplarily, the weather station terminal may be configured with a first timer, and the first timer is set to serve the weather sensor. Therefore, in the process of collecting the weather data by the weather station terminal, the weather station terminal may specifically include:

When the first timer reaches the preset data collection time point, the weather station terminal wakes up the weather sensor, and collects weather data through the weather sensor.

It can be understood that in this application, the weather sensor is in a dormant state and is not in a normal working state (not a standard working state) when it is not awakened, and will not sense weather data. Power request, effectively reduce the power consumption of the weather station terminal.

Exemplarily, the weather station terminal may also be configured with a second timer, and the second timer is configured to serve the low-orbit satellite communication module. Therefore, when the weather station terminal detects that the low-orbit satellite is over-the-top, In the process of transmitting meteorological data to low-orbit satellites, it can include:

When the second timer reaches the preset low-orbit satellite passing time point, the weather station terminal wakes up the low-orbit satellite communication module, and transmits the weather data to the low-orbit satellite through the low-orbit satellite communication module.

It can be understood that in this application, the low-orbit satellite communication module is in a dormant state and is not in a normal working state (not a standard working state) when it is not awakened, and will not capture satellite signals. In this way, it can greatly reduce the number of low-orbit satellites. The communication module asks for the power supply of the weather station terminal, which effectively reduces the power consumption of the weather station terminal.

Further, the above-mentioned sleep mechanism that can effectively reduce the power consumption of the weather station terminal can also be understood in conjunction with a schematic diagram of a workflow of the weather station terminal of the present application shown in FIG. 4 .

In addition, in the sleep mechanism of the low-orbit satellite communication module, as another practical implementation method, a verification mechanism can be introduced before waking up to ensure effective waking up to perform data transmission work.

Specifically, when the second timer reaches the preset low-orbit satellite passing time point, the weather station terminal wakes up the low-orbit satellite communication module, and transmits the meteorological data to the low-orbit satellite through the low-orbit satellite communication module. Also includes:

The weather station terminal detects whether the register stores new weather data that has not yet been transmitted in this transmission cycle;

If so, trigger when the second timer reaches the preset low-orbit satellite crossing time point, wake up the low-orbit satellite communication module, and transmit the weather data to the low-orbit satellite through the low-orbit satellite communication module;

If not, it will not be triggered. When the second timer reaches the preset low-orbit satellite overtop time point, wake up the low-orbit satellite communication module, and transmit the weather data to the low-orbit satellite through the low-orbit satellite communication module.

It is easy to see that, in the present application, when the weather station terminal locally stores the weather data, it can be stored in a register.

In the time period between the last low-orbit satellite over-the-top time point and the new low-orbit satellite over-the-top time point, if no new meteorological data is collected, that is, the new data that has not yet been transmitted in this transmission cycle. For meteorological data, there is no need to perform data transmission work and do not wake up the low-orbit satellite communication module, which can further enhance the power consumption reduction effect brought by the sleep mechanism.

In addition, for the storage of the above meteorological data (stored by storage devices such as registers) and the transmission of meteorological data (transmitted by the low-orbit satellite communication module), the first-in-first-out principle can also be used. The problem of data accumulation can be effectively avoided, and the data obtained earlier can be processed first, improving the organization and efficiency of data processing.

The above is the introduction of the method for transmitting meteorological data based on low-orbit satellite communication provided by this application. In order to facilitate better implementation of the method for transmitting meteorological data based on low-orbit satellite communication provided by this application, this application also provides from the perspective of functional modules.
