Description

Technical Field

[0001] The present invention relates to the technical field of meteorological information transmission systems, and in particular to a glacier meteorological information transmission system based on Beidou satellites. Background Art

[0002] Meteorological monitoring can obtain meteorological information in the atmosphere in real time, such as temperature, humidity, air pressure, wind speed, etc., so as to make accurate forecasts for future weather. This has important guiding significance for people's daily life, travel, agricultural production and commercial activities. Long-term series of meteorological data can be obtained. By analyzing these data, we can understand the laws and trends of climate change and provide important scientific basis for climate change research. Glaciers, as important carriers of global freshwater reserves, are crucial to maintaining water resources in many regions. By monitoring glacier meteorology, we can better understand and predict glacier changes, thus providing important data support for global water resources management.

[0003] In the existing technology, unmanned monitoring stations are generally used to collect glacier meteorological data, and the collected meteorological data are transmitted to meteorological centers and other places through satellite communication technology. Meteorological monitoring equipment often needs to collect multiple data of various meteorological types, and the data volume is generally large. When communicating through satellite, the bandwidth occupied is high and the time is long. It is easy to be interfered, which increases the possibility of data transmission failure. After failure, retransmission is required, which leads to higher data usage costs. Since the glacier coverage area is generally large, multiple unmanned monitoring stations are usually required to carry out meteorological collection work. Therefore, it is often necessary to equip multiple satellite communication equipment to transmit data separately, increase the number of satellite communications, and increase the possibility of transmission failure. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a glacier meteorological information transmission system based on Beidou satellite, which is used to solve the technical problem that when transmitting meteorological data via satellite in the existing scheme, the large amount of meteorological data may easily lead to transmission failure.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] It includes a meteorological collection module, a cluster communication module, a glacier communication module, a satellite communication module, a ground communication module and a control module, among which:

[0007] A meteorological collection module includes a plurality of meteorological collection devices, each of which has a unique code. The plurality of meteorological collection devices are distributed at various locations on the glacier at a certain distance, and are used to collect meteorological data at locations where the devices are located. The meteorological data includes multiple categories, and the collected meteorological data and unique codes are packaged to obtain a meteorological data packet;

[0008] The cluster communication module is used to establish a communication connection between the meteorological collection module and the glacier communication module, and send the meteorological data packet to the glacier communication module;

[0009] The glacier communication module includes a processing unit, a temporary storage unit and a transceiver unit. The processing unit is used to process the received meteorological data packet into a transmission data packet. The temporary storage unit is used to store the transmission data packet. The transceiver unit is used to control the antenna, establish communication interaction with the satellite communication module, send the transmission data packet to the communication satellite and receive the feedback packet.

[0010] The satellite communication module obtains the transmission data packet sent by the glacier communication module, and forwards the received transmission data packet to the ground communication module, receives the feedback packet sent by the ground communication module, and forwards the received feedback packet to the glacier communication module;

[0011] The ground communication module establishes communication interaction with the satellite communication module, is used to receive data sent by the satellite communication module and parse it to obtain meteorological data, and send a feedback package to the satellite communication module;

[0012] The control module is used to adjust the working parameters of the meteorological collection module, the cluster communication module and the glacier communication module.

[0013] The meteorological data collected by multiple meteorological collection modules are transmitted to the glacier communication module for unified transmission, which reduces the frequency of satellite communications, thereby reducing the number of satellite communications and reducing the possibility of transmission failure.

[0014] Furthermore, the meteorological collection equipment includes a variety of sensors and storage units. The meteorological collection equipment collects meteorological data of corresponding categories through sensors. The categories of meteorological data include temperature, humidity, wind speed and air pressure. The collection module uses sensors to collect meteorological data, and the storage unit is used to temporarily store meteorological data packets; the meteorological data includes an identification field, a data set, a unique code and a collection period. The identification field corresponds one-to-one to the meteorological data type, and the data set corresponds one-to-one to the identification field. The data set is a set of data collected by the sensor over a period of time.

[0015] Furthermore, the processing of the meteorological data packet into a sending data packet includes the following steps: after receiving the meteorological data packet, extracting the data set therein as the original data set; streamlining the original data set; and merging the data after streamlining all the data sets to obtain a sending data packet.

[0016] Furthermore, the streamlining of the original data set includes:

[0017] The deviation degree PX of the data in the original data set is calculated. The calculation formula of the deviation degree PX is expressed as:

[0018]

[0019] Where A i represents the i-th data in the original data set, n represents the total number of data in the original data set, and a represents the average value of the data in the data set;

[0020] Determine the relationship between the deviation degree PX and the preset deviation threshold M,

[0021] If PX≤M, delete all data in the original data set and insert a data value a to complete the simplification of the original data set;

[0022] If PX>M, perform exception processing on the original data set, retain the maximum and minimum values ​​in the original data set after exception processing, delete other values ​​in the original data set, and complete the processing of the original data set.

[0023] Furthermore, the calculation formula of the abnormality is expressed as: Where YC i Represents the abnormality of the i-th data in the data set, where A i Represents the i-th data in the data set, A i±1 Represents any adjacent data of the i-th data in the data set;

[0024] The abnormal processing of the original data set includes:

[0025] S1, read the maximum and minimum values ​​in the original data set;

[0026] S2, calculate the digits of the maximum and minimum values ​​in the original data set;

[0027] S3. According to the number of digits where the maximum and minimum values ​​are located, use the abnormality calculation formula to calculate the abnormality YC of the two values ​​respectively. i ;

[0028] S4. If YC exists i > N, then delete the i-th data in the original data set and perform exception processing again, where N is the preset exception threshold. If there is no YC i >N, the exception processing of the data set is completed.

[0029] The meteorological data is pre-processed through the processing unit, which greatly reduces the amount of data while ensuring the reliability and effectiveness of the processed data, thereby reducing the demand for satellite communication bandwidth and the time required to transmit and receive data, reducing communication costs while reducing the risk of interference and improving the reliability of information transmission.

[0030] Furthermore, the cluster communication module includes a radio terminal, which is arranged on the meteorological collection device and the glacier communication module. The radio terminal is used to establish a communication connection between the meteorological collection module and the glacier communication module. The cluster communication module sends the meteorological data packet stored in the storage unit of the meteorological collection module to the glacier communication module, and the meteorological data packet is deleted from the storage unit after successful sending.

[0031] Furthermore, the Glacier communication module starts the antenna to establish communication interaction with the satellite communication module, and sends the sending data packet in the temporary storage unit to the satellite communication module. The satellite communication module forwards the sending data packet to the ground communication module. After the ground receiving module receives the sending data packet, it sends a feedback packet to the satellite communication module. The satellite communication module forwards the feedback packet to the Glacier communication module. The Glacier communication module performs corresponding operations according to the feedback packet.

[0032] Furthermore, the working parameters of the meteorological collection module include a collection period and a collection frequency, the working parameters of the cluster communication module include a broadcast period, and the working parameters of the glacier communication module include a communication period. The collection period does not overlap with the broadcast period, and the broadcast period does not overlap with the communication period.

[0033] By setting up the control module, the working hours of the meteorological collection module, cluster communication module and glacier communication module are controlled, so that the staff can control the work of each module according to work needs. At the same time, the time-divided work of each module can effectively balance the energy consumption of the equipment system and improve the reliability of the system.

[0034] Furthermore, the feedback package includes receiving information and control information, the receiving information includes receiving success or receiving failure, and the control information is empty data or working parameter data, wherein the receiving information is automatically generated by a data verification method and the control information is manually input, and the Glacier communication module performs corresponding operations according to the feedback package, including: when the receiving information is receiving failure, sending the sending data packet again and waiting for the feedback packet; when the receiving information is receiving success, deleting the sending data packet in the temporary storage unit, turning off the antenna and checking the control information, and no operation is performed when the control information is empty data; when the control information is a working data parameter, transmitting the control information to the control module.

[0035] Furthermore, when the control module receives the working data parameters, it adjusts the working parameters of the meteorological collection module, the cluster communication module and the glacier communication module according to the working data parameters during the most recent broadcast period, and the control module controls the adjusted working parameters to take effect after the end of this broadcast period.

[0036] The present invention provides a glacier meteorological information transmission system based on Beidou satellites. It has the following beneficial effects:

[0037] 1. By setting up a cluster communication system, the meteorological data collected by multiple meteorological collection modules are transmitted to the glacier communication module for unified transmission, which reduces the frequency of satellite communications, thereby reducing the number of satellite communications and the possibility of transmission failure. At the same time, the meteorological data is pre-processed through the processing unit, which greatly reduces the amount of data while ensuring the reliability and effectiveness of the processed data, thereby reducing the demand for satellite communication bandwidth and the time required to transmit and receive data, reducing communication costs while reducing the risk of interference and improving the reliability of information transmission.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1

[0045] Please refer to Figure 1-4 The present invention provides a glacier meteorological information transmission system based on Beidou satellite, a control module, including a meteorological collection module, a cluster communication module, a glacier communication module, a satellite communication module and a ground communication module, wherein:

[0046] The control module is used to adjust the working parameters of the meteorological collection module, the cluster communication module and the glacier communication module.

[0047] The meteorological collection module includes multiple meteorological collection devices, each of which has a unique code. The multiple meteorological collection devices are distributed at various locations on the glacier at a certain distance and are used to collect meteorological data at the locations where the devices are located. The meteorological data contains multiple categories, and the collected meteorological data and unique codes are packaged to obtain a meteorological data packet;

[0048] The cluster communication module is used to establish a communication connection between the meteorological collection module and the glacier communication module, and send the meteorological data packet to the glacier communication module;

[0049] The glacier communication module includes a processing unit, a temporary storage unit and a transceiver unit. The processing unit is used to process the received meteorological data packet into a transmission data packet. The temporary storage unit is used to store the transmission data packet. The transceiver unit is used to control the antenna, establish communication interaction with the satellite communication module, send the transmission data packet to the communication satellite and receive the feedback packet.

[0050] The satellite communication module obtains the transmission data packet sent by the glacier communication module, and forwards the received transmission data packet to the ground communication module, receives the feedback packet sent by the ground communication module, and forwards the received feedback packet to the glacier communication module;

[0051] The ground communication module establishes communication interaction with the satellite communication module, is used to receive data sent by the satellite communication module and parse it to obtain meteorological data, and send a feedback package to the satellite communication module;

[0052] Meteorological data collection equipment includes a variety of sensors and storage units. Meteorological data collection equipment collects meteorological data of corresponding categories through sensors. The categories of meteorological data include temperature, humidity, wind speed and air pressure. The collection module uses sensors to collect meteorological data, and the storage unit is used to temporarily store meteorological data packets; meteorological data includes identification fields, data sets, unique codes and collection time periods. The identification fields correspond one-to-one to the meteorological data types, and the data sets correspond one-to-one to the identification fields. The data set is a collection of data collected by the sensor over a period of time.

[0053] Since the glacier area is generally large, multiple collection devices are needed to be distributed at different locations on the glacier to collect meteorological data. Each device has a corresponding number, and the number can be used to determine the collection location corresponding to the meteorological data.

[0054] The meteorological data packet processing is a sending data packet, which includes the following steps: after receiving the meteorological data packet, extracting the data set therein as the original data set; streamlining the original data set; and merging the data after streamlining all the data sets to obtain the sending data packet.

[0055] The streamlining of the original data set includes:

[0056] Calculate the deviation degree PX of the data in the original data set. The calculation formula of the deviation degree PX is expressed as:

[0057]

[0058] Where A i represents the i-th data in the original data set, n represents the total number of data in the original data set, and a represents the average value of the data in the data set;

[0059] Determine the relationship between the deviation degree PX and the preset deviation threshold M,

[0060] If PX≤M, delete all data in the original data set and insert a data value a to complete the processing of the original data set;

[0061] If PX>M, perform exception processing on the original data set, retain the maximum and minimum values ​​in the original data set after exception processing, delete other values ​​in the original data set, and complete the processing of the original data set.

[0062] The calculation formula of abnormality is expressed as: Where YC i Represents the abnormality of the i-th data in the data set, where A i Represents the i-th data in the data set, A i±1 Represents any adjacent data of the i-th data in the data set;

[0063] Exception processing of the original data set includes:

[0064] S1, read the maximum and minimum values ​​in the original data set;

[0065] S2, calculate the digits of the maximum and minimum values ​​in the original data set;

[0066] S3. According to the number of digits where the maximum and minimum values ​​are located, use the abnormality calculation formula to calculate the abnormality YC of the two values ​​respectively. i ;

[0067] S4. If YC exists i > N, then delete the i-th data in the original data set and perform exception processing again, where N is the preset exception threshold. If there is no YC i >N, the exception processing of the data set is completed.

[0068] The cluster communication module includes a radio terminal, which is set on the meteorological collection equipment and the glacier communication module. The radio terminal is used to establish a communication connection between the meteorological collection module and the glacier communication module. The cluster communication module sends the meteorological data packet stored in the storage unit of the meteorological collection module to the glacier communication module. The meteorological data packet is deleted from the storage unit after successful sending.

[0069] The Glacier communication module starts the antenna to establish communication interaction with the satellite communication module, and sends the sending data packet in the temporary storage unit to the satellite communication module. The satellite communication module forwards the sending data packet to the ground communication module. After receiving the sending data packet, the ground receiving module sends a feedback packet to the satellite communication module. The satellite communication module forwards the feedback packet to the Glacier communication module. The Glacier communication module performs corresponding operations according to the feedback packet.

[0070] The meteorological data collected by multiple acquisition modules are sent to the Glacier communication module for processing and then sent. There is no need to configure a satellite communication device for each acquisition device, which effectively reduces the cost of system use. At the same time, the centralized transmission of meteorological data reduces the difficulty of receiving meteorological data, and there is no need to wait for reception one by one, which improves the work efficiency of receiving meteorological data. At the same time, the Glacier communication module processes the meteorological data and uses the formula

[0071]

[0072] Calculate the deviation degree in the original data set. The deviation degree represents the degree of deviation of each data in the data set relative to the average value of the data set. When the calculated deviation degree is less than the preset deviation threshold, it means that the meteorological data has not changed much during this period of time. Therefore, only the average value of the data in the data set is needed to more accurately represent the data, which ensures data reliability while greatly reducing the amount of data.

[0073] When the calculated deviation value is greater than the preset deviation threshold, it means that the meteorological data has changed significantly. The degree of abnormality shows the degree of change between the data and the adjacent data. If the degree of change is higher than a certain value, it means that the data has suddenly changed significantly. The data is very likely to be abnormal data. The abnormality of the maximum and minimum values ​​in the data is calculated and compared with the preset abnormality threshold. The abnormal values ​​are deleted and the maximum and minimum values ​​in the data set are retained. After eliminating the interference of abnormal data, only the maximum and minimum values ​​are retained, which effectively reflects the changes in meteorological data while reducing the amount of data. In this embodiment, the deviation threshold and the abnormality threshold can be set based on the experience of the staff. By streamlining the meteorological data, the processed data is guaranteed to be reliable and effective while greatly reducing the amount of data, thereby reducing the demand for satellite communication bandwidth and the time required to transmit and receive data, reducing the cost of satellite communication while reducing the risk of interference and improving the reliability of information transmission.

[0074] Embodiment 2

[0075] Based on the above-mentioned embodiment 1, the working parameters of the meteorological collection module include the collection period and the collection frequency, the working parameters of the cluster communication module include the broadcast period, and the working parameters of the glacier communication module include the communication period. The collection period does not overlap with the broadcast period, and the broadcast period does not overlap with the communication period.

[0076] Each module works within a set corresponding time period. In this embodiment, each time period can be set by the staff according to work needs. At the same time, the time period operation of each module can effectively balance the energy consumption of the equipment system and improve the reliability of the system.

[0077] The feedback package includes receiving information and control information. The receiving information includes receiving success or receiving failure, and the control information is empty data or working parameter data. The receiving information is automatically generated by the data verification method and the control information is manually input. The Glacier communication module performs corresponding operations according to the feedback package, including: when the receiving information is receiving failure, sending the sending data packet again and waiting for the feedback packet; when the receiving information is receiving success, deleting the sending data packet in the temporary storage unit, turning off the antenna and checking the control information. When the control information is empty data, no operation is performed; when the control information is working data parameters, the control information is transmitted to the control module.

[0078] When the control module receives the working data parameters, it adjusts the working parameters of the meteorological collection module, the cluster communication module and the glacier communication module according to the working data parameters during the most recent broadcast period. The adjusted working parameters of the control module take effect after the end of this broadcast period.

[0079] In the present embodiment, the method for judging whether information reception is successful or failed may be existing technologies such as the parity check method. Through the feedback package, when data transmission fails, the message can be immediately transmitted to the Glacier communication module, so that the Glacier communication module can resend the data to ensure that the meteorological data can be transmitted correctly. At the same time, the system's operating parameters can be adjusted instantly according to needs through control information, thereby improving the practicality of the system.
