[0050] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0052] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. These should be regarded as exemplary and are only intended to illustrate the feasibility of implementing the technical solution of this application. However, it does not mean that the applicant has used or necessarily used the solution.

[0053] To facilitate understanding, the following will be combined with... Figure 1 The scenarios to which the embodiments of this application are applicable will be described.

[0054] Figure 1 This is a schematic diagram illustrating a scenario using a satellite communication device provided in an embodiment of this application. Please refer to [link / reference]. Figure 1 It includes N functional modules, which are the first functional module, the second functional module, and so on up to the Nth functional module, where N is an integer greater than or equal to 2. Each functional module is distributed and deployed in different physical locations according to its own needs. For example, when the functional module is an RF receiver module, the RF receiver module needs to be deployed close to the antenna to reduce signal attenuation.

[0055] A failure in any one of N functional modules can lead to a malfunction in satellite communication equipment. In related technologies, when a satellite communication device malfunctions, technicians need to travel to the physical locations corresponding to each functional module and inspect them one by one to identify the faulty module. However, manually traveling back and forth between these dispersed locations to inspect each functional module is time-consuming, resulting in low maintenance efficiency for satellite communication equipment.

[0056] This application provides a communication status detection device and a satellite communication device. The communication status detection device includes a control device, multiple fault detection devices corresponding to multiple functional modules of the satellite communication device, and a status indication device. The fault detection devices are connected to their respective functional modules, and the multiple fault detection devices are also connected to the control device. The control device is connected to the status indication device, which includes multiple areas corresponding to the multiple functional modules. Each area indicates the status of its corresponding functional module. In this method, the fault detection device collects the operating parameters of the corresponding functional module and generates a status detection code corresponding to that functional module based on the operating parameters and preset conditions. The control device drives the indicator lights in the corresponding areas of each functional module according to the status detection codes. This allows the status indication device to intuitively display the status of each functional module (e.g., normal, warning, or fault) through the indicator lights in the corresponding areas. Consequently, faulty modules can be directly identified through the status indication device, eliminating the need for manual inspection of each functional module's physical location, significantly improving the maintenance efficiency of the satellite communication device.

[0057] The data storage system shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; for the same or similar content, the description will not be repeated in different embodiments.

[0058] Figure 2 Schematic diagram of the communication status detection device provided in the embodiments of this application Figure 1 .like Figure 2 As shown, the communication status detection device 20 includes: a control device 21, a fault detection device group 22, and a status indication device 23.

[0059] The communication status detection device 20 is integrated into the satellite communication equipment 2.

[0060] The functional module group 10 of the satellite communication equipment 2 corresponds to the fault detection device group 22 and the status indication device 23.

[0061] Specifically, when the functional module group 10 includes N functional modules, the fault detection device group 22 includes N fault detection devices corresponding one-to-one with the N functional modules, and the status indication device 23 includes N regions corresponding one-to-one with the N functional modules. The N functional modules include a first functional module, a second functional module, and so on up to the Nth functional module; the N fault detection devices include a first fault detection device, a second fault detection device, and so on up to the Nth fault detection device; and the N regions include a first region, a second region, and so on up to the Nth region.

[0062] One functional module corresponds to one fault detection device and one area. For example, a first functional module corresponds to a first fault detection device and a first area.

[0063] Each fault detection device is connected to its corresponding functional module. For example, the first fault detection device is connected to its corresponding first functional module.

[0064] Multiple fault detection devices are also connected to the control device 21. Specifically, the first fault detection device, the second fault detection device, and the Nth fault detection device are connected to the control device via an I2C bus.

[0065] The control unit 21 includes an Advanced Reduced Instruction Set Computing (ARM) processor.

[0066] The control device 21 is also connected to the status indication device 23. Specifically, the first region, the second region to the Nth region are connected to the control device 21 through the Serial Peripheral Interface (SPI) bus.

[0067] The fault detection device is used to collect the operating parameters of the corresponding functional modules and generate the status detection code corresponding to the functional module based on the operating parameters and the preset conditions corresponding to the operating parameters.

[0068] The status detection code includes the code corresponding to the number of the functional module and the status code corresponding to the functional module.

[0069] When the status code corresponding to a functional module indicates a fault in the functional module, the status detection code also includes the code corresponding to the fault parameters. The fault parameters are the operating condition parameters of the functional module.

[0070] In some embodiments, a state detection code corresponding to the functional module is generated based on the operating parameters and the preset conditions corresponding to the operating parameters, including:

[0071] When the operating parameters meet the preset conditions, the status detection code corresponding to the functional module includes the code corresponding to the number of the functional module and the status code corresponding to the functional module. At this time, the status code corresponding to the functional module indicates that the functional module is normal.

[0072] When the operating parameters do not meet the preset conditions, the status detection code corresponding to the functional module includes the code corresponding to the functional module number, the status code corresponding to the functional module, and the code corresponding to the fault parameter. At this time, the status code corresponding to the functional module indicates that the functional module is faulty.

[0073] Each functional module is numbered and has a one-to-one correspondence with its functional module. The encoding corresponding to each functional module number can occupy 1 byte, meaning the encoding of each functional module number is an 8-bit binary code.

[0074] For example, when the status code corresponding to a functional module indicates that the functional module is normal, the status code corresponding to the functional module can be 1. At this time, the status code corresponding to the functional module can occupy 1 byte, that is, the status code corresponding to the functional module is an 8-bit binary code, occupying 8 bits in 1 byte, with the first bit being 1 and the rest being 0, for example, 10000000.

[0075] When the status code corresponding to a functional module indicates a functional module fault, the status code can be 0. In this case, the status code corresponding to the functional module and the code corresponding to the fault parameter can occupy 1 byte, that is, the status code corresponding to the functional module and the code corresponding to the fault parameter are 8-bit binary codes, with the first bit being 0 and the rest being the code corresponding to the fault parameter.

[0076] The control device 21 is used to acquire the status detection codes corresponding to each functional module and generate data codes based on the status detection codes corresponding to each functional module.

[0077] Optionally, the control device 21 periodically acquires the status detection codes corresponding to each functional module at a first preset time interval. The first preset time interval is, for example, 500ms.

[0078] Data encoding includes status codes corresponding to multiple functional modules and module information codes corresponding to functional modules that have experienced failures.

[0079] Status codes are used to indicate which of the multiple functional modules has failed.

[0080] The status codes corresponding to multiple functional modules include the status codes of each functional module, with each functional module's status code occupying 1 bit. For example, when the status code of a functional module is 1, it indicates that the functional module is in a normal state, and when the status code of a functional module is 0, it indicates that the functional module is in an abnormal state. Abnormal states include warning states and fault states.

[0081] The number of bytes occupied by the status codes corresponding to multiple functional modules can be adjusted according to the number of functional modules. The status codes corresponding to multiple functional modules can occupy 2 bytes.

[0082] The module information encoding corresponding to the malfunctioning functional module includes the encoding of the malfunctioning functional module number, the encoding of the fault type, and the encoding of the fault parameters. The module information encoding corresponding to the malfunctioning functional module can occupy 8 bytes, of which the encoding of the malfunctioning functional module number can occupy 1 byte, the encoding of the fault type can occupy 1 byte, the encoding of the fault parameters can occupy 4 bytes, and 2 bytes are reserved.

[0083] Data encoding may also include encoding corresponding to a fixed identifier, encoding corresponding to the identifier of a satellite communication device, encoding corresponding to the detection time of a control device, and encoding corresponding to a first check code.

[0084] The fixed identifier indicates the format of the data encoding. The encoding corresponding to the fixed identifier can occupy 2 bytes. The fixed identifier is used by the management device to quickly identify the format followed by the current data encoding, ensuring that the management device can correctly decode the data encoding according to the corresponding parsing rules, and avoiding parsing errors caused by unclear data encoding format.

[0085] Each satellite communication device has a unique identifier that corresponds to a specific satellite communication device. The identifier for a satellite communication device can occupy 4 bytes of encoding.

[0086] The detection time of the control device is the timestamp of the data encoding generated by the control device. The encoding corresponding to the detection time of the control device can occupy 4 bytes.

[0087] All encodings used in this application are binary codes. Hexadecimal codes will be converted to binary codes by default; the conversion method can be found in relevant technologies and will not be elaborated here.

[0088] The first checksum is used to verify the integrity and accuracy of the data encoding during transmission. The checksum occupies 2 bytes. For example, the first checksum is 0x1F8A.

[0089] In the embodiments of this application, the number of bytes occupied by the encoding can be adjusted according to the actual situation. For example, when the number of functional modules is 12, at least 12 bits are required, so the status encoding corresponding to multiple functional modules can occupy 2 bytes. When the number of functional modules is 20, at least 20 bits are required, so the status encoding corresponding to multiple functional modules can occupy 3 bytes.

[0090] Each area includes M indicator lights, where M is an integer greater than 0.

[0091] The control device 21 is also used to drive M indicator lights in the area corresponding to each functional module according to the status detection code corresponding to each functional module.

[0092] Specifically, the control device outputs a pulse width modulation (PWM) signal based on the status detection code corresponding to each functional module, driving M indicator lights in the area corresponding to each functional module.

[0093] The area is fan-shaped, and the indicator lights in the area include multiple colors and / or multiple brightness levels. These multiple colors and / or multiple brightness levels are associated with multiple states of the functional modules corresponding to the area.

[0094] M indicator lights can be evenly distributed within the area (e.g., arranged along the radius of a fan or along an arc). By superimposing the light from the M indicator lights, uniform brightness can be ensured throughout the area, avoiding blind spots and allowing the status of each functional module to be clearly observed from different angles.

[0095] The following examples, 1A, 1B, and 1C, illustrate the association between various states of functional modules corresponding to multiple colors and / or multiple brightness levels and regions.

[0096] Example 1A: Multiple colors are associated with multiple states of the functional modules corresponding to the areas:

[0097] When the state detection code corresponding to the functional module indicates different states of the functional module, the M indicator lights in the corresponding areas of each functional module will display different colors.

[0098] For example, when the status detection code corresponding to a functional module indicates that the functional module is normal, the M indicator lights in the area corresponding to each functional module are driven to turn green; when the status detection code corresponding to a functional module indicates that the functional module is faulty for less than 3 seconds, the M indicator lights in the area corresponding to each functional module are driven to turn yellow; when the status detection code corresponding to a functional module indicates that the functional module is faulty for more than 3 seconds, the M indicator lights in the area corresponding to each functional module are driven to turn red.

[0099] Example 1B: Multiple brightness levels are associated with multiple states of the functional modules corresponding to the regions:

[0100] When the state detection code corresponding to the functional module indicates different states of the functional module, it drives the M indicator lights in the area corresponding to each functional module to present different brightness levels.

[0101] For example, when the status detection code corresponding to a functional module indicates that the functional module is normal, the M indicator lights in the area corresponding to each functional module are driven to display 20% brightness; when the status detection code corresponding to a functional module indicates a fault for less than 3 seconds, the M indicator lights in the area corresponding to each functional module are driven to display 50% brightness; when the status detection code corresponding to a functional module indicates a fault for more than 3 seconds, the M indicator lights in the area corresponding to each functional module are driven to display 100% brightness.

[0102] Example 1C: Multiple colors and brightness levels are associated with multiple states of the functional modules corresponding to the regions.

[0103] When the state detection code corresponding to the functional module indicates different states of the functional module, it drives the M indicator lights in the corresponding areas of each functional module to display different colors and different brightness.

[0104] For example, when the status detection code corresponding to a functional module indicates that the functional module is normal, the M indicator lights in the area corresponding to each functional module are driven to turn green and have a brightness of 20%; when the status detection code corresponding to a functional module indicates a fault for less than 3 seconds, the M indicator lights in the area corresponding to each functional module are driven to turn yellow and have a brightness of 50%; when the status detection code corresponding to a functional module indicates a fault for more than 3 seconds, the M indicator lights in the area corresponding to each functional module are driven to turn red and have a brightness of 100%.

[0105] In this embodiment, the communication status detection device includes a control device, multiple fault detection devices corresponding to multiple functional modules of the satellite communication equipment, and a status indication device. The fault detection devices are connected to their respective functional modules, and the multiple fault detection devices are also connected to the control device. The control device is connected to the status indication device, which includes multiple areas corresponding to the multiple functional modules. These areas are used to indicate the status of the corresponding functional modules. Through this method, the status indication device can intuitively display the status (e.g., normal or faulty) of each functional module through its corresponding areas. This allows for direct identification of faulty modules without requiring manual inspection at the physical locations of each functional module, significantly improving the maintenance efficiency of the satellite communication equipment. Compared to the average locating time of faulty functional modules in related technologies (28.7 minutes), this embodiment reduces this average time to 47 seconds, an improvement of 97.3%, demonstrating a significant improvement in the maintenance efficiency of satellite communication equipment.

[0106] Furthermore, improving the efficiency of communication status detection devices can prevent satellite communication equipment from operating with faults, thereby enhancing the stability and service life of satellite communication equipment. Preventing satellite communication equipment from operating with faults can also improve the success rate of low-temperature startup of satellite communication equipment.
