Before describing the method for transmitting meteorological data based on low earth orbit satellite communication provided by the present application, the background related to the present application will be described first.
The low-orbit satellite communication-based meteorological data transmission method, the low-orbit satellite communication-based meteorological data transmission device and the computer-readable storage medium can be applied to a meteorological station terminal and are used for introducing low-orbit satellite communication into the meteorological station terminal, so that the meteorological data transmission work can be completed with low power consumption under the condition of not being limited by a ground communication network.
The execution subject of the low-earth-orbit-satellite-communication-based meteorological data transmission method can be a low-earth-orbit-satellite-communication-based meteorological data transmission device or a meteorological station terminal integrated with the low-earth-orbit-satellite-communication-based meteorological data transmission device. The transmission device of the meteorological data based on the low earth orbit satellite communication can be realized in a hardware or software mode, and the meteorological station terminal can be set in a device cluster mode.
Next, a method for transmitting meteorological data based on low earth orbit satellite communication provided by the present application will be described.
First, referring to fig. 1, fig. 1 shows a schematic flow chart of a method for transmitting meteorological data based on low earth orbit satellite communication according to the present application, where the method for transmitting meteorological data based on low earth orbit satellite communication according to the present application may specifically include the following steps:
s101, a weather station terminal acquires weather data through a configured weather sensor;
it can be understood that, this application is in the meteorological data acquisition link of terminal position in the meteorological work after having introduced low orbit satellite communication, because can communicate in a flexible way, conveniently to the day, consequently the equipment that carries out meteorological data acquisition work then can put away the fixed deployment position of original equipment, can deploy in the site environment according to meteorological data's collection demand in a flexible way, as a neotype meteorological station terminal configuration, has broken through the region and has used the restriction, has expanded the use scene.
The weather station terminal can be configured with corresponding weather sensors according to the preset weather data acquisition requirements, so that the original weather data can be acquired under the working control of the weather station terminal, and the data of subsequent weather work can be used.
As an example, the weather station terminal may comprise a weather sensor and a weather station control center, and the weather station control center may be understood as a control device, and may control the weather data acquisition operation of the weather sensor and perform the weather data transmission operation according to a control command written in advance, and may also control the weather data acquisition operation of the weather sensor and perform the weather data transmission operation according to the received control command.
In practice, the weather sensors and the weather station control center are configured independently, so that each weather sensor can be deployed in a specific environment in a wider range.
The control center of the weather station comprises a Micro Controller Unit (MCU), a power module, a low-orbit satellite communication module, a memory, even a positioning module (a positioning module of a type such as a GPS module) and other hardware structures, and is used for realizing the work of the weather station terminal except the weather data acquisition work of a weather sensor.
The meteorological station control center, which can also be called a meteorological station body, and the meteorological sensors outside the meteorological station control center are mutually independent.
Of course, in some application scenarios, the weather sensor may also be disposed on the weather station body.
As a practical implementation manner, in practical applications, the meteorological sensor may specifically include at least one of different types of meteorological sensors, such as a wind speed sensor, a wind direction sensor, a rainfall sensor, an air pressure sensor, a temperature and humidity sensor, and an illumination sensor.
For the connection between the weather sensor and the weather station body, besides the wired communication connection based on the data transmission line (for example, the wired communication mode based on the interfaces of RS485, I2C, RS232 and the like), the wireless communication connection can be preferably adopted.
Specifically, as another practical implementation manner, a wireless communication connection manner of different wireless communication connection manners such as bluetooth communication, Wi-Fi or LoRa may be adopted between the weather station terminal body and the weather sensor, so that the weather sensor is more conveniently deployed in space, and the condition that a wired communication line is inconvenient to be deployed in a specific field environment may be overcome.
In particular, as to the structural composition of the weather station terminal, the structural composition of the weather station terminal can be understood by referring to a structural schematic diagram of the weather station terminal shown in fig. 2.
Step S102, the weather station terminal stores weather data;
after the meteorological data is acquired by the meteorological sensor, the meteorological station terminal can locally store the meteorological data.
It can be understood that the weather station terminal does not transmit the weather data in the first time after acquiring the weather data, and the weather station terminal transmits the weather data under the condition of having the best low-orbit satellite communication quality in consideration of the requirement of reducing power consumption.
Therefore, in each waiting time period, the meteorological data is stored firstly, the data summarization effect is achieved, and the transmission work of the meteorological data is carried out when the time point with the best low-orbit satellite communication quality is reached.
And S103, when the weather station terminal detects that the low-orbit satellite is over the top, the weather station terminal transmits the weather data to the low-orbit satellite and instructs the low-orbit satellite to transmit the weather data to the data processing center through the low-orbit satellite communication system, so that the data processing center executes preset weather data processing work according to the weather data.
Specifically, the time point with the best communication quality of the low-orbit satellite is configured to be the time point when the low-orbit satellite passes through the top, that is, when the low-orbit satellite passes through the top of the terminal of the weather station, the condition with the best communication quality of the low-orbit satellite is achieved, and then the transmission work of the weather data can be carried out.
It is understood that the low orbit satellite corresponds to a low orbit satellite communication system, which completes the retransmission of relevant signals through the low orbit satellite on the day and the satellite ground station on the ground.
Therefore, the meteorological data can be transmitted to the ground satellite ground station from the low-orbit satellite communication module of the meteorological station terminal through the low-orbit satellite on the sky, and then transmitted to the data processing center preset in the meteorological work, and the data processing center completes the corresponding meteorological work.
It can be understood that low-orbit satellite communication can effectively reduce the communication energy consumption requirement compared with high-orbit satellite communication, and then can prolong the service life of a terminal in practical application, and is particularly suitable for meteorological environment monitoring scenes in areas without power or networks.
Further, referring to a scene schematic diagram of the low earth orbit satellite communication-based meteorological data transmission method shown in fig. 3, after meteorological data is processed by meteorological work, a data processing result can be sent to a user side, and effects of viewing meteorological workers, viewing meteorological forecasts by the public and the like are achieved.
As can be seen from the embodiment shown in fig. 1, for the transmission of meteorological data, the present application configures a low-orbit satellite communication module on a meteorological station terminal, so that after the meteorological data is collected and stored, when the low-orbit satellite is detected to pass the top, can transmit meteorological data to a low orbit satellite, and transmit the meteorological data to a data processing center through a low orbit satellite communication system, so that the data processing center executes preset meteorological data processing work according to the meteorological data, in the process, the weather station terminal can communicate with the weather station terminal to transmit the weather data, thereby avoiding the limitation of the ground communication network in the prior art, and secondly, the low-orbit satellite communication can bring lower energy consumption than the high-orbit satellite communication, so that the meteorological data transmission work can be completed with low power consumption under the condition of not being limited by a ground communication network, and the meteorological data acquisition work can be better completed.
Further, in practical application, different specific optimization schemes and adaptive schemes can be configured.
As another practical implementation manner, in order to further reduce the power consumption of the weather station terminal, a hibernation mechanism may be further introduced, so that the relevant devices of the weather station terminal may be in a hibernation state when not performing the preset operation, thereby greatly reducing the power consumption of the relevant devices.
For example, the weather station terminal may be configured with a first timer, which is configured to serve the weather sensor, so that the weather station terminal may specifically include, during the process of acquiring weather data by the weather sensor:
when the first timer reaches the preset data acquisition time point, the weather station terminal wakes up the weather sensor and acquires the weather data through the weather sensor.
It can be understood that in this application, meteorological sensor is in dormant state, not normal operating condition (not standard operating condition) when not awakening up, can not go to respond to meteorological data, so, can the power of greatly reduced meteorological sensor to meteorological station terminal asks for, effectively reduces the consumption at meteorological station terminal.
For example, the weather station terminal may be configured with a second timer configured to serve the low-orbit satellite communication module, so that the process of transmitting the weather data to the low-orbit satellite when the weather station terminal detects that the low-orbit satellite is over the top may specifically include:
when the second timer reaches a preset low-orbit satellite over-top time point, the weather station terminal wakes up the low-orbit satellite communication module and transmits weather data to the low-orbit satellite through the low-orbit satellite communication module.
It can be understood that in this application, the low earth orbit satellite communication module is in dormant state, not normal operating condition (not standard operating condition) when not awakening up, can not go to catch the satellite signal, so, the power of low earth orbit satellite communication module that can significantly reduce to weather station terminal asks for, effectively reduces the consumption at weather station terminal.
Further, for the sleep mechanism capable of effectively reducing the power consumption of the weather station terminal, the sleep mechanism can be understood by combining with a work flow diagram of the weather station terminal shown in fig. 4.
In addition, as another practical implementation manner, in the sleep mechanism of the low earth orbit satellite communication module, a verification mechanism can be further introduced before waking up, so as to ensure effective waking up to perform data transmission work.
Specifically, when the second timer reaches the time point when the preset low earth orbit satellite crosses the top, the weather station terminal wakes up the low earth orbit satellite communication module and transmits the weather data to the low earth orbit satellite through the low earth orbit satellite communication module, and the method can further include:
the method comprises the steps that a weather station terminal detects whether a register stores new weather data which are not transmitted in a transmission period;
if yes, triggering to wake up the low-orbit satellite communication module when the second timer reaches a preset low-orbit satellite over-top time point, and transmitting meteorological data to the low-orbit satellite through the low-orbit satellite communication module;
if not, the low-orbit satellite communication module is awakened when the second timer reaches a preset low-orbit satellite over-top time point without triggering, and the meteorological data is transmitted to the low-orbit satellite through the low-orbit satellite communication module.
It is easy to see that, in the present application, the weather station terminal can store the weather data in the register when locally storing the weather data.
In the time period from the last low-orbit satellite overhead time point to the new one-time low-orbit satellite overhead time point, if new meteorological data are not acquired, namely the new meteorological data which are not transmitted in the transmission period are not completed, data transmission work is not required, and the low-orbit satellite communication module is not awakened, so that the effect of reducing power consumption brought by a sleep mechanism can be further enhanced.
In addition, in the working process of storing the meteorological data (stored by a storage device such as a register) and transmitting the meteorological data (transmitted by a low-orbit satellite communication module), the meteorological data can be specifically executed by adopting a first-in first-out principle, so that the problem of data accumulation can be effectively avoided, the data acquired earlier can be processed first, and the orderliness and the processing efficiency of data processing are improved.
The above is the introduction of the method for transmitting meteorological data based on low earth orbit satellite communication provided by the present application, and the method for transmitting meteorological data based on low earth orbit satellite communication provided by the present application is convenient for better implementation.
