Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The satellite ground test is an important and key step in the satellite development process, and can simulate the working state of a satellite during in-orbit operation and test the functions and the performances of each system component of the satellite. The satellite ground test interface (referred to as satellite ground test interface for short) is an important way for transmitting data outwards during satellite ground test, and the current working state of the satellite can be known in real time through the data.
At present, data transmitted by a satellite ground test interface is generally transmitted in a wired communication mode such as serial port communication RS422\232 \485. The method for transmitting data through a serial port communication RS422\232 \485cable by a satellite ground detection port has the following defects: firstly, when the satellite ground test port data is subjected to cable transmission, cables need to be arranged in a test field in advance, manpower and material resources are consumed, meanwhile, the requirements on hard conditions such as the environment and the space of the test field are high, the use occasions have certain limitations, and the upgrading expansibility of the test cables and equipment is not strong. And secondly, in a serial port communication wired transmission mode, when the satellite performs solar wing driving mechanism testing and solar cell array illumination testing, the test cables are wound and pulled by the overturning, hanging and sun wing spreading of the satellite, so that the test work is inconvenient to spread. Third, the wired communication transmission distance and transmission rate of serial communication are limited. Under a relatively long communication distance, the transmission rate of the serial port communication wired transmission mode is relatively low. For example, the length of the RS-422 balanced twisted pair is inversely proportional to its transmission rate, the maximum transmission distance of the RS-422 balanced twisted pair is about 1200 meters, and the maximum transmission rate is 10Mb/s. The RS-422 balanced twisted pair can achieve higher transmission rates only at relatively short communication distances. When the transmission rate is below 100kb/s, the maximum transmission distance of 1200 m is possible with the RS-422 balanced twisted pair. Thus, the maximum transmission rate achievable over a twisted pair of wires, typically 100 meters in length, is only 1Mb/s. Fourthly, the farther the distance between serial communication is, the test cost is increased violently by the serial communication extension cable, the test equipment convenience is poor, the problem of movement is limited, meanwhile, the networking capability of serial wired communication is poor, and the networking process is complex. And fifthly, the external environment is judged manually, and different transparent transmission modes are selected according to the external environment, so that the accuracy of selecting the satellite transparent transmission mode is greatly influenced, and the effect of transparent transmission of the satellite ground survey port data is influenced.
In summary, when the data is transparently transmitted through the satellite ground measurement port, different transparent transmission modes are not convenient to select according to different environments, so that the data transparent transmission effect of the satellite ground measurement port is influenced.
In order to solve the technical problems, the present application provides a method, a system, a device and a medium for wireless transparent transmission of satellite ground test port data, and before introducing a specific technical scheme of the present application, a hardware operating environment related to the scheme of the embodiment of the present application is introduced first.

Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may include a Display (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a WIreless interface (e.g., a WIreless-FIdelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the communication device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a data storage module, a network communication module, a user interface module, and an electronic program.
In the communication apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the communication device of the present invention may be disposed in the communication device, and the communication device invokes the satellite ground socket data wireless transparent transmission device stored in the memory 1005 through the processor 1001, and executes the satellite ground socket data wireless transparent transmission method provided in the embodiment of the present invention.
Referring to fig. 2, based on the hardware environment of the foregoing embodiment, an embodiment of the present application provides a wireless transparent transmission method for satellite ground test port data, where the method is applied to a wireless transparent transmission system for satellite ground test port data, where the system includes multiple wireless transparent transmission modules, and the system is used to connect the satellite ground test port module and a satellite ground device; the multiple wireless transparent transmission modules at least comprise a first wireless transparent transmission module and a second wireless transparent transmission module with different performances; the method comprises the following steps:
s10: when the satellite ground test port module and the satellite ground equipment meet a first preset environment condition, the first wireless transparent transmission module is selected, so that the satellite ground test port module and the satellite ground equipment can conduct wireless transparent transmission through the first wireless transparent transmission module.
In the specific implementation process, the satellite ground test module is used for receiving data information sent by a satellite, and the satellite ground detection equipment is used for receiving signals transmitted by the wireless transparent transmission module. The wireless transparent transmission technology is a data transmission technology, the wireless transparent transmission is wireless transparent transmission, the transparent transmission is that in the data transmission process, the length and the content of data of a sender and a receiver are completely consistent, the data do not need to be processed, the transparent transmission is equivalent to a data line or a serial port line, the wireless transparent transmission method is suitable for most standard or non-standard user protocols, and the application range is very wide. LoRa is a low-power consumption local area network wireless standard, and the LoRa technology is characterized in that the distance of transmission is longer than that of other wireless modes under the same power consumption condition, the low power consumption and long distance unification is realized, and the distance is enlarged by 3-5 times than that of the traditional wireless radio frequency communication under the same power consumption condition. Besides the advantage of sensitivity, the LoRa can realize long-distance transmission, and the factor is the super-strong anti-interference capability. LoRa has 20dB of noise and still can communicate the interference killing feature.
A wireless transparent transmission module is also used, as shown in fig. 3, and fig. 3 is a schematic diagram of the wireless transparent transmission module provided in the embodiment of the present application. The wireless transparent transmission module consists of a wireless module, a wireless antenna end and a serial RS422 communication end. The wireless transparent double-transmission module can also carry out networking through configuration parameters, namely one wireless module transmits and a plurality of wireless modules receive, compared with wired communication, the technical method of wireless transparent transmission can enable satellite ground port testing data transmission to be more convenient, transmission distance breaks through the traditional serial port communication distance, and receiving equipment is more convenient and more mobile.
In one embodiment, the first wireless transparent module is an SX1280PA module; the first preset environmental condition includes: the distance between the satellite ground port measuring module and the satellite ground detection equipment is less than 2km, or a frequency signal existing in a test environment between the satellite ground port measuring module and the satellite ground detection equipment is 400-600 MHZ, or the amount of data to be transmitted between the satellite ground port measuring module and the satellite ground detection equipment is larger than a first preset value, for example, the first preset value can be set to be 1000M. Specifically, when the satellite ground test port module and the satellite ground test equipment meet any one of the first preset environmental conditions, the first wireless transparent transmission module is selected, so that the satellite ground test port module and the satellite ground test equipment perform wireless transparent transmission through the first wireless transparent transmission module. Namely, when data detection is carried out on the satellite ground detection port, automatic detection is carried out on the external environment, and if the distance between the detected satellite ground detection port module and the satellite ground detection equipment is less than 2km and/or the frequency signal existing in the test environment between the satellite ground detection port module and the satellite ground detection equipment is 400-600 MHZ and/or the data volume to be transmitted between the satellite ground detection port module and the satellite ground detection equipment is larger than a first preset value, the software system automatically selects a first wireless transparent transmission module, namely an SX1280PA module. More specifically, when a satellite is tested in a closed space such as an assembly room, the SX1280PA module can be automatically selected to be started to obtain a higher transmission rate when the test satellite is closer to a ground inspection device (less than 2 km), channel conflicts and wireless signal crosstalk problems can also exist when a plurality of wireless devices exist in a satellite ground test environment, although the SX1278/SX1280PA module has better anti-interference capability, the SX1280PA module can be influenced in a complex electromagnetic environment, and the SX1280PA module can be automatically selected to transmit data when a large number of low-frequency signals (the frequency signals are 400-600 MHZ) exist in the test environment.
S11: and when the satellite ground measuring port module and the satellite ground equipment meet a second preset environment condition, selecting the second wireless transparent transmission module so that the satellite ground measuring port module and the satellite ground equipment can perform wireless transparent transmission through the second wireless transparent transmission module.
In a specific implementation process, the second wireless transparent transmission module is an SX1278 module, and the second preset environmental condition includes: the distance between the satellite ground port measuring module and the satellite ground equipment is greater than or equal to 2km, or the frequency signal existing in the testing environment between the satellite ground port measuring module and the satellite ground equipment is 2.4-2.5 GHz, or the data quantity to be transmitted between the satellite ground port measuring module and the satellite ground equipment is smaller than a second preset value, and the second preset value is smaller than the first preset value.
Specifically, when the satellite ground test port module and the satellite ground equipment meet any one of the second preset environmental conditions, the second wireless transparent transmission module is selected, so that the satellite ground test port module and the satellite ground equipment perform wireless transparent transmission through the second wireless transparent transmission module. The method comprises the steps that when data detection is carried out on a satellite ground detection port, automatic detection is carried out on the external environment, if the distance between a satellite ground detection port module and satellite ground detection equipment is detected to be larger than or equal to 2km, and/or frequency signals existing in the test environment between the satellite ground detection port module and the satellite ground detection equipment are detected to be 2.4-2.5 GHZ, and/or the quantity of data to be transmitted between the satellite ground detection port module and the satellite ground detection equipment is smaller than a second preset value. The software system automatically selects the first wireless pass-through module, the SX1278 module. More specifically, the satellite can select to start an SX1278 module to support remote testing when the distance between a transmitting field or a testing point and ground detection equipment is far (more than or equal to 2 km), the wireless transparent transmission communication distance can reach 3km under the condition of no interference around clear weather, and can reach 6km under the condition of primary relay communication, and secondary relay communication is supported; the satellite ground test environment has the problems of channel conflict and wireless signal crosstalk when a plurality of wireless devices exist, and although the SX1278/SX1280PA module has good anti-interference capability, the SX1278/SX1280PA module can be influenced under a complex electromagnetic environment. When more high-frequency signals (the frequency signals are 2.4-2.5 GHZ), the SX1278 module can be selected to transmit data, so that the problem that the signals are interfered can be avoided; during satellite ground test, if the influence of the signal on the wireless signal is large when the weather condition is transmitted outdoors, the high-frequency signal attenuation of the SX1280PA module is more severe in thunderstorm days or when the weather is more cloudy, the signal attenuation of the SX1278 module is weaker, and the transmission effect of the SX1278 module for transmitting data is more ideal than that of the SX1280PA module, so that the SX1278 module can be selected to transmit the signal under the condition that the weather condition is not ideal.
In summary, when data is required to be transmitted through the satellite ground test port, if a first preset environmental condition is met between the satellite ground test port module and the satellite ground equipment, the first wireless transmission module is selected to enable the satellite ground test port module and the satellite ground equipment to perform wireless transmission; and if the second preset environment condition is met between the satellite ground test port module and the satellite ground detection equipment, selecting the second wireless transparent transmission module to enable the satellite ground test port module and the satellite ground detection equipment to perform wireless transparent transmission. Namely, the method is based on a wireless transparent transmission system comprising a plurality of wireless transparent transmission modules, when the external environments (namely preset environmental conditions) of the satellite ground test port data transparent transmission are different, the corresponding wireless transparent transmission module can be automatically selected according to different external environments to perform the wireless transparent transmission on the satellite ground test port data, and the external environments do not need to be judged artificially and then the corresponding wireless transparent transmission module is selected. Therefore, compared with the manual selection of the wireless transparent transmission module, the method can more accurately and efficiently select the corresponding wireless transparent transmission module, so that the satellite ground test port data transparent transmission effect can be greatly improved. Meanwhile, wireless transparent transmission is carried out between the satellite ground port measuring module and the satellite ground equipment through the wireless transparent transmission module, so that compared with the prior art, the transparent transmission distance through wired transparent transmission is longer, and the data transparent transmission speed is higher under a long distance. Therefore, the limitation on the distance of the satellite ground test serial port communication is smaller, the influence on the satellite ground test port data transmission is smaller, and the state of the target satellite can be known in real time conveniently.
In order to more accurately select the first wireless transparent transmission module and the second wireless transparent transmission module, in some embodiments, before the step of performing wireless transparent transmission between the satellite ground test port module and the satellite ground equipment through the first wireless transparent transmission module, when the satellite ground test port module and the satellite ground equipment meet a first preset environmental condition, the method further includes:
acquiring a propagation attenuation data value of the first wireless transparent transmission module and a propagation attenuation data value of the second wireless transparent transmission module based on the built test environment, physical model and radio wave propagation attenuation model;
when the propagation attenuation data value of the first wireless transparent transmission module is smaller than that of the second wireless transparent transmission module, selecting the first wireless transparent transmission module to enable the satellite ground detection port module and the satellite ground detection equipment to perform wireless transparent transmission through the first wireless transparent transmission module; and when the propagation attenuation data value of the first wireless transparent transmission module is greater than that of the second wireless transparent transmission module, selecting the second wireless transparent transmission module to enable the satellite ground detection port module and the satellite ground detection equipment to perform wireless transparent transmission through the second wireless transparent transmission module.
In this embodiment, if the only first wireless transparent transmission module or the only second wireless transparent transmission module can be selected according to the external environment or the related preset condition, the selection may be performed according to the above manner. However, in the actual selection process, it is found that some external environments or preset conditions can meet the requirements of both the first wireless transparent transmission module and the second wireless transparent transmission module, that is, at this time, both the first wireless transparent transmission module and the second wireless transparent transmission module can be selected. In this case, it is necessary to select the most ideal wireless transparent transmission module more finely according to the propagation attenuation data values of the first wireless transparent transmission module and the second wireless transparent transmission module.
Specifically, the propagation attenuation data value of the first wireless transparent transmission module and the propagation attenuation data value of the second wireless transparent transmission module are calculated in advance based on the built test environment, the physical model and the radio wave propagation attenuation model. The propagation attenuation data value of the first wireless transparent transmission module and the propagation attenuation data value of the second wireless transparent transmission module can be calculated more efficiently through a physical model and a radio wave propagation attenuation model which are constructed in advance. Specifically, the physical model is obtained by the following relational expression:
Pt-Pr+Gt+Gr=20㏒(4Πfd/c)+Lc+Lo
where Pt denotes transmission power of the transmitter, pr denotes sensitivity of the receiver, gt denotes transmission antenna gain, gr denotes reception antenna gain, f denotes carrier frequency, d denotes distance between the antenna receiving the signal and the antenna transmitting the signal, c denotes light speed, lc denotes feeder insertion loss of the transmission antenna, and Lo denotes air propagation loss due to the environment.
The radio wave propagation attenuation model is obtained by the following relational expression:
Lo= 32.44 + 20㏒d+ 20㏒f
the distance between the antenna for receiving the signal and the antenna for transmitting the signal is km, and the carrier frequency is MHZ.
As shown in table 1, the air propagation loss of the common wireless transparent transmission module due to the environment is shown.
TABLE 1 airborne propagation loss of wireless transparent transmission module due to environment
According to the table 1, the air propagation loss caused by the environment to the wireless transparent transmission module can be obtained more efficiently, and under the condition that the propagation attenuation data value of the first wireless transparent transmission module and the propagation attenuation data value of the second wireless transparent transmission module are obtained. If the propagation attenuation data value of the first wireless transparent transmission module is smaller than that of the second wireless transparent transmission module, selecting the first wireless transparent transmission module, and enabling the satellite ground test port module and the satellite ground equipment to conduct wireless transparent transmission through the first wireless transparent transmission module; and if the propagation attenuation data value of the first wireless transparent transmission module is greater than that of the second wireless transparent transmission module, selecting the second wireless transparent transmission module, and enabling the satellite ground port measuring module and the satellite ground equipment to perform wireless transparent transmission through the second wireless transparent transmission module. Therefore, more accurate and more appropriate wireless transparent transmission module can be selected to be applied to detection of satellite ground measurement port data, and therefore the effect and efficiency of satellite ground measurement port data transparent transmission can be further improved.
The first wireless transparent transmission module and the second wireless transparent transmission module selected according to the method have the following specific applications:
the application one is as follows: the conventional wired mode of the satellite ground port data RS422 communication is changed into a wireless transparent transmission mode.
Specifically, as shown in fig. 4, two selected first wireless transparent transmission modules or second wireless transparent transmission modules are used. And two first wireless transparent transmission modules or two second wireless transparent transmission modules are connected wirelessly, one wireless transparent transmission module is arranged at a satellite ground detection port, one wireless transparent transmission module is arranged at a satellite ground detection device end, the satellite ground detection port and the satellite ground detection device are connected to the wireless transparent transmission module through RS422 in a wired mode, the wireless transparent transmission module converts RS422 serial port communication signals into wireless signals and sends the wireless signals through a wireless transparent transmission module antenna, and the other wireless transparent transmission module antenna receives the wireless signals again, converts the wireless signals into wired signals through the other wireless transparent transmission module and transmits the wired signals to the satellite ground detection device. Data are transmitted between the two infinite transparent transmission modules in a wireless communication mode, so that the purpose of wireless communication between the satellite ground measuring port and the satellite ground measuring equipment is achieved. When satellite ground test is carried out, if serial port communication RS422 is used for wired data transmission, a test cable needs to be arranged in advance, and a test site needs to have enough space; if the test environment is changed by the test satellite, the test cable needs to be changed, so that the whole test process becomes complicated, and the test is inconvenient to rapidly expand. If the technical scheme of wireless transparent transmission is adopted at the satellite ground test port, planning and arrangement of a test cable is not needed in the early stage of test; when the test environment and the test items of the test satellite change, the layout of the test cable is not required to be changed, the equipment universality is better, and the problems of poor convenience, limited movement and the like of test equipment are solved. The satellite ground survey mouthful data transmission mode changes from wired transmission into wireless transmission among this application promptly, can avoid arranging the demand of cable in advance, and wireless passthrough is lower to the place environment requirement simultaneously, and it is more convenient to test the use.
The application II comprises the following steps: the satellite ground test port data wireless transparent transmission method is applied to the solar wing driving mechanism test and the solar cell array illumination test of the satellite.
Specifically, as shown in fig. 5, the wireless transparent transmission module is fixed on the complete satellite, and the wireless transparent transmission module and the complete satellite are connected through a short-distance RS422 in a wired manner; the satellite and the wireless transparent transmission module are hung on the test tool as a whole, and data are transmitted through the wireless transparent transmission module. During testing: the satellite sends data to the wireless transparent transmission module through the ground detection port, and the wireless transparent transmission module converts the RS422 data into wireless signals to be sent out through the antenna; and the wireless transparent transmission module antenna at the satellite ground equipment end receives the wireless data and converts the wireless data into RS422 serial port data to be sent to the satellite ground equipment. And (3) testing process: a satellite integral rotation action test, a satellite integral turning action test, a satellite sailboard unfolding test and the like; by adopting the wireless transparent transmission method, the problems of mutual interference of cables, cable winding, cable pulling and the like are solved, the application is safer and more convenient, and the test development is facilitated. When the satellite is used for testing the solar wing driving mechanism and the solar cell array illumination test on the ground, the satellite needs to be suspended and rotated so as to facilitate the unfolding of the solar wing. The method for serial port communication wired data transmission can cause test cables to be mutually wound when the satellite is in rotation test, and can also damage the satellite structure to bring unnecessary trouble to the test. If the wireless transparent transmission technology in the application is adopted to transmit data, the whole wireless transparent transmission module positioned at the satellite ground test interface can move synchronously along with the satellite, so that the mutual winding of test cables is avoided.
The application is as follows: the method for wirelessly transmitting the satellite ground test port data is applied to testing in a long-distance scene or a scene with different heights (satellite launching field testing).
Specifically, serial communication wired transmission is used in satellite ground test, and serial communication RS422 wired transmission data is generally used. However, the transmission distance and the transmission rate of serial port communication are limited, for example, the length of the RS-422 balanced twisted pair is inversely proportional to its transmission rate, and the maximum transmission distance of the RS-422 balanced twisted pair is about 1200 meters. And the communication distance of the satellite ground port measurement data can reach 3km by adopting a wireless transparent transmission method under the condition of no interference around, and can reach 6km under the condition of primary relay communication. The test cable is extended to cause a surge in test cost due to the long distance of the serial communication cable transmission. In addition, serial ports wired communication need connect more cable when carrying out the network deployment, and the process is loaded down with trivial details and inefficiency, and wireless passing module only need carry out the network deployment through configuration parameter, and a wireless passing module sends promptly, and a plurality of wireless passing modules receive, and the operation is convenient high-efficient than wired network deployment mode.
As shown in fig. 6, the device under test satellite and the wireless transparent transmission module are in the environment of space one (for example, when testing in a distant test room or a launching field rocket fairing), and the device under test satellite is in the environment of space two; and transmitting the satellite ground detection port data to satellite ground detection equipment in the second space in a wireless transparent transmission mode (note that because the signal is poor after the wireless signal is shielded, transparent transmission windows are preferably reserved in the wireless transparent transmission of all the two rooms or the antenna of the wireless transparent transmission module is placed outside the windows). When testing in the satellite launching field, the satellite is located the rocket radome fairing and has certain difference in height with test ground, if use wired communication transmission data, the cable of use must be long enough, and the cable of overlength can influence the test, and it is also inconvenient to use. If data are transmitted in a wireless transparent transmission mode and in a wireless test environment, a test cable is not needed, the test distance is longer, the cable cost is saved, and the use is more convenient.
According to the method, the satellite ground test port data are transmitted in a wireless mode, the problem that cables need to be arranged in advance in a test field in a complex and labor-consuming mode is solved, the adaptability to the hard conditions such as the environment and the space of the test field is high, the universality is high, and the use is convenient. When the satellite carries out the test of solar wing actuating mechanism and solar cell array illumination experiment, when overturning, rotatory, hanging in midair the operation to the satellite, solved the problem that the test cable twined, was dragged, makes things convenient for the expansion of test work. The communication distance of the satellite ground test port data wireless transparent transmission mode is longer than the serial port wired transmission distance, the data transmission rate is higher under a long distance, the networking between the wireless transparent transmission modules is more convenient and faster than the serial port wired communication, and the testing is more convenient, faster and more flexible when the space test is far away or the satellite tests in a launching field rocket fairing. The technical scheme of wireless transparent transmission solves the problems that the testing cost is increased violently, the convenience of testing equipment is poor and the movement is limited due to wired communication extension cables. The wireless transparent transmission has strong expansibility, after a test environment is established, new equipment is often added due to the needs of the system or the change of the test, if a serial port wired transmission mode is adopted, rewiring is needed, the construction is complicated, the original communication line is possibly damaged, and if a special wireless data transmission mode is established by the wireless transparent transmission equipment, the expansion of the system can be realized only by connecting the newly added equipment with the test equipment. Compared with the traditional wireless transparent transmission technology, the wireless transparent transmission double-module (SX 1278/SX1280PA module) is wider in application range, not only can be used for long-distance low-rate communication, but also can be used for medium-distance long-distance high-rate communication, and meanwhile, compared with the traditional wireless transparent transmission technology, the double-module using the LoRa technology is higher in anti-jamming capability. By adopting the free space propagation model formula, the test environment can be evaluated more accurately and rapidly to select the corresponding wireless module, so that the test efficiency can be improved, and the test result is more accurate.
