Fig. 1 is a schematic structural diagram of an embodiment of a terrestrial satellite device according to the present application, and referring to fig. 1, a terrestrial satellite device 10 includes a communication module 11, which communicates with a satellite, and includes at least one interrupt pin 111, for example, 4 interrupt pins 111a-111d, wherein one interrupt pin, for example, the interrupt pin 111a, of the at least one interrupt pin 111 is configured to represent a transit state during satellite communication and a communication state of the communication module 11.
It is understood that, of the 4 interrupt pins 111a-111d, one of the three interrupt pins except the interrupt pin 111a may be configured to characterize a transit state during satellite communication and a communication state of the communication module 11, for example, the interrupt pin 111b may be configured to characterize a transit state during satellite communication and a communication state of the communication module 11, or the interrupt pin 111c may be configured to characterize a transit state during satellite communication and a communication state of the communication module 11, or the interrupt pin 111d may be configured to characterize a transit state during satellite communication and a communication state of the communication module 11, which is not particularly limited, and the interrupt pin 111a is taken as an example for the following description.
The terrestrial satellite device 10 includes a communication module 11, and the communication module 11 is configured to communicate with a satellite to implement data transceiving between the terrestrial satellite device 10 and the satellite. The communication mode between the communication module 11 and the satellite may be half-duplex communication or full-duplex communication.
A transit state is understood to mean a state in which the satellite passes over the ground satellite device 10, i.e. the satellite enters the coverage area of the ground satellite device 10 until the satellite moves out of the coverage area. When the satellite passes by, the communication module 11 can establish connection with the satellite, and at this time, the communication module 11 is in a communication state, and the communication module 11 and the satellite can transmit and receive data to and from each other; after the satellite passes by the border, the communication module 11 is disconnected from the satellite, the communication module 11 ends the communication state, and data is not transmitted and received between the communication module 11 and the satellite.
The transit state includes a first transit state and a second transit state, the first transit state represents that the satellite transit starts, that is, the satellite enters the coverage area of the ground satellite device 10, and the second transit state represents that the satellite transit ends, that is, the satellite moves out of the coverage area of the ground satellite device 10. The communication state of the communication module 11 includes a transmitting state and a receiving state, after the satellite enters the coverage area of the terrestrial satellite device 10, the communication module 11 establishes a connection with the satellite, and the communication module 11 is in the communication state including the transmitting state and the receiving state. When the communication module 11 is in the transmission state, the communication module 11 can transmit data to the satellite; when the communication module 11 is in the receiving state, the communication module 11 can receive data transmitted from a satellite.
The interrupt pin 111a of the communication module 11 is configured to characterize a transit state at the time of satellite communication and a communication state of the communication module 11. That is, the interrupt pin 111a can represent not only the transit state during satellite communication but also the communication state of the communication module 11.
It should be noted that, in the embodiment of fig. 1, although the communication module 11 is shown to include 4 interrupt pins 111a to 111d, the application is not limited thereto, and the communication module 11 may also include one interrupt pin 111, or another number of interrupt pins 111, for example, 2, 3, 5, or another number that can be implemented, which is not specifically limited.
According to the scheme, the communication module 11 is arranged to communicate with the satellite, wherein the communication module 11 comprises at least one interrupt pin 111, and one interrupt pin 111a is configured to represent the transit state during satellite communication and the communication state of the communication module 11, so that the use number of the interrupt pins 111 can be reduced, the cost is reduced, and the software processing efficiency can be improved.
As mentioned above, one interrupt pin 111a of the communication module 11 is configured to characterize the transit state during the satellite communication and the communication state of the communication module 11, and in an embodiment of the present application, one interrupt pin 111a is triggered to be an interrupt, so that within one interrupt, one interrupt pin 111a is configured to be a preset level rule to characterize the transit state during the satellite communication and the communication state of the communication module 11.
The interrupt pin 111a in the communication module 11 is triggered to be an interrupt, that is, the interrupt pin 111a receives a control instruction, for example, an interrupt signal triggered by a high level or a low level, and further triggers generation of an interrupt. Thus, within this interrupt, the interrupt pin 111a is configured to preset level rules, that is, the transit state at the time of satellite communication and the communication state of the communication module 11 are characterized by the preset level rules.
It can be understood that the interrupt pin 111a of the communication module 11 is triggered to be interrupted, and after the interruption is started, the transit state during satellite communication and the communication state of the communication module 11 are represented by a preset level rule. For example, the level rule may include a transition between a high level and a low level, and in one interrupt, the interrupt pin 111a is configured to be a transition between a high level and a low level, so as to characterize the transit state during satellite communication and the communication state of the communication module 11, that is, the first transit state of the satellite, the second transit state of the satellite, the transmission state of the communication module 11 and the reception state of the communication module 11 are characterized by a transition between a high level and a low level. The specific level rule may be set according to an actual use situation, and is not particularly limited. And when the satellite transit is finished, namely the transit state of the satellite is the second transit state, ending the interruption.
As mentioned above, the interrupt pin 111a is configured to preset level rules to characterize the transit state during the satellite communication and the communication state of the communication module 11, in an embodiment of the present application, one interrupt pin 111a is configured to be at a first level within a first time period to characterize the transit state during the satellite communication; one interrupt pin 111a is configured to be at a first level or a second level for a second period of time, representing the communication state of the communication module 11; wherein the first period is different from the second period, and the first level is different from the second level.
The interrupt pin 111a of the communication module 11 is configured to a first level for a first period of time for characterizing a transit state during satellite communication, and the interrupt pin 111a is configured to a first level for a second period of time or directly configured to a second level for characterizing a communication state of the communication module 11.
That is, the preset level rule includes a first level in the first time period, a second level, and a first level in the second time period, and further represents the transit state during satellite communication and the communication state of the communication module 11 through the transition of the first level in the first time period, the first level in the second time period, and the second level.
The first time period is different from the second time period, and both the first time period and the second time period can be set according to actual use requirements, and are not particularly limited. The first level is different from the second level, and the first level and the second level may be set to a high level or a low level, respectively, for example, the first level is a high level, and the second level is a low level; or the first level is a low level, and the second level is a high level, which may be set according to actual use requirements, and is not specifically limited.
It can be understood that the interrupt pin 111a is a first level in a first time period to represent a transit state during satellite communication, and the interrupt pin 111a is a first level or a second level in a second time period to represent a communication state of the communication module 11, and further, by determining that the interrupt pin 111a is the first level in the first time period or the first level or the second level in the second time period, the transit state of the satellite and the communication state of the communication module 11 are represented by one interrupt pin 111 a.
For example, the first level is high, the second level is low, and the interrupt pin 111a is high for a first period of time, indicating that the satellite is in a transit state. The interrupt pin 111a is at a high level or a low level in a second time period, which indicates that the communication module 11 is in a communication state, wherein the interrupt pin 111a is at a high level in the second time period, which indicates that the communication module 11 is in a transmission state, and the interrupt pin 111a is at a low level, which indicates that the communication module 11 is in a reception state; alternatively, the interrupt pin 111a is at a high level in the second time period, which indicates that the communication module 11 is in the receiving state, and the interrupt pin 111a is at a low level, which indicates that the communication module 11 is in the transmitting state.
In an embodiment of the present application, the first time period is less than the second time period by a preset time.
The first time period is smaller than the preset time of the second time period, and the specific time can be set according to actual use requirements without specific limitation. It can be understood that the duration of the first time period may be much shorter than the duration of the second time period, and the specific durations of the first time period and the second time period may be set according to actual use requirements, and are not particularly limited.
Assuming that the first time period is 0.1 ms and the second time period is 1 s, taking the above-mentioned first level as high level and the second level as low level as an example for explanation, the interrupt pin 111a in the communication module 11 gives high level within 0.1 s, and it can be understood that the interrupt pin 111a gives instantaneous high level, which represents a transit state of the satellite during communication; the interrupt pin 111a gives a high level or directly gives a low level within 1 second, indicating that the communication module 11 is in a communication state.
As described above, the communication state includes the transmission state and the reception state, the interrupt pin 111a is configured to be at the first level or the second level in the second time period to represent the communication state of the communication module 11, and in an embodiment of the present application, one interrupt pin 111a is configured to be at the first level in the second time period to represent the transmission state; one interrupt pin 111a is configured to a second level to characterize the receiving state.
It can be understood that, in the communication process between the communication module 11 and the satellite, when the communication module 11 is in the transmitting state, the communication module can transmit data to the satellite, and when the communication module 11 is in the receiving state, the communication module can receive data transmitted by the satellite. The interrupt pin 111a in the communication module 11 is configured to be at the first level in the second time period, so as to characterize the transmission state of the communication module 11; the interrupt pin 111a is configured to a second level for characterizing a receiving state.
When the interrupt pin 111a is configured to the second level, the duration of the second level may be the second time period, that is, the interrupt pin 111a is configured to the second level of the second time period, or the duration of the second level may also be other time periods.
The first level is different from the second level to distinguish the transmitting state and the receiving state of the communication module 11, the first level may be a high level or a low level, and the second level may be a low level or a high level. For example, the interrupt pin 111a of the communication module 11 is configured to be at a high level in the second period of time to represent the transmission state of the communication module 11, and the interrupt pin 111a is configured to be at a low level to represent the reception state of the communication module 11. Alternatively, the interrupt pin 111a of the communication module 11 is configured to be at a low level in the second time period to represent the transmission state of the communication module 11, and the interrupt pin 111a is configured to be at a high level to represent the reception state of the communication module 11.
Taking the above-mentioned first level as a high level and the second level as a low level as an example, the interrupt pin 111a is a high level in a first time period, which indicates a transit state of the satellite during communication, and the communication module 11 establishes a connection with the satellite; the interrupt pin 111a is at a low level, which indicates that the communication module 11 is in a receiving state, and at this time, the communication module 11 can receive data transmitted from a satellite; the interrupt pin 111a is at a high level in the second time period, which indicates that the communication module 11 is in a transmitting state, and at this time, the communication module 11 can transmit data to the satellite, so that the transit state of the satellite and the transmitting state and the receiving state of the communication module 11 are represented by one interrupt pin 111 a.
As described above, the interrupt pin 111a is configured to the first level for the second period of time to represent the transmission state and configured to the second level to represent the reception state. In an embodiment of the present application, in one interrupt, one interrupt pin 111a is spaced to a second level and a first level for a second period of time to characterize the receive state and transmit state spacing.
That is, during the interruption, the communication module 11 is half-duplex communication, i.e. the communication module 11 and the satellite can transmit data in both directions, but one channel can only transmit data in one direction at the same time. In one interrupt, one interrupt pin 111a of the communication module 11 is configured to be spaced to the second level and the first level in the second time period to characterize the receiving state and the transmitting state interval of the communication module 11, i.e. the communication module 11 is not in the transmitting state and the receiving state at the same time.
Next, referring to fig. 2, fig. 2 is a schematic diagram of level changes of the interrupt pin according to an embodiment of the present application, and the above-mentioned first level is a high level and the second level is a low level, where the high level is denoted by 1, the low level is denoted by 0, the horizontal axis t represents time, and the positive direction of the horizontal axis represents a time sequence direction. t11 represents a first time period, t22 represents a second time period, t21 represents a time period for providing the second level, and the time duration of t21 may be equal to the time duration of t22, or any other achievable time duration, and may be set according to an actual use requirement, and is not particularly limited.
The interrupt pin 111a of the communication module 11 is set to a high level in t11, which indicates that the satellite is in a first transit state of transit states, that is, the satellite enters a coverage area of the terrestrial satellite device 10, the satellite establishes a connection with the communication module 11, and the communication module 11 is in a communication state. Next, the interrupt pin 111a gives a high level in t22, indicating that the communication module 11 is in a transmission state, and the communication module 11 can transmit data to the satellite; next, the interrupt pin 111a again gives a low level in t21, which indicates that the communication module 11 is in a receiving state, and the communication module 11 can receive data transmitted by the satellite; next, the interrupt pin 111a gives a high level again in t22, which indicates that the communication module 11 is in a transmission state and the communication module 11 can transmit data to the satellite; next, the interrupt pin 111a again gives a low level in t21, which indicates that the communication module 11 is in a receiving state, and at this time, the communication module 11 can receive data transmitted from the satellite; that is, the sending state and the receiving state of the communication module 11 occur at intervals, but do not occur at the same time, so as to indicate that the communication module 11 is in half-duplex communication; next, the interrupt pin 111a gives a high level in t11, which indicates that the satellite is in the second transit state of the transit states, that is, the satellite moves out of the coverage area of the terrestrial satellite device 10, the satellite is disconnected from the communication module 11, and the communication state of the communication module 11 is ended.
In one embodiment of the present application, one interrupt pin 111a is configured to a first level for a first period of time to also characterize triggering of one interrupt.
The interrupt pin 111a of the communication module 11 is configured to a first level for a first period of time and is also used to characterize the triggering of an interrupt. It will be appreciated that the interrupt pin 111a is configured to a first level for a first period of time, indicative of both a transit condition during satellite communications and triggering an interrupt. For example, the interrupt pin 111a of the communication module 11 is at a high level for a first period of time, which indicates that an interrupt is triggered and also indicates a transit state during satellite communication.
As described above, the interrupt pin 111a is configured to a first level for a first period of time to also characterize triggering an interrupt. In an embodiment of the present application, the transit states include a first transit state and a second transit state, the first transit state represents a satellite transit start, the second transit state represents a satellite transit end, and a time interval between the first transit state and the second transit state is a duration of an interrupt.
It can be understood that the interrupt pin 111a provides the first level in the first time period to indicate the first transit state of the satellite transit state, and further indicates that an interrupt is triggered, and the interrupt pin 111a provides the first level in the first time period to indicate the second transit state of the satellite transit state, and further indicates that the interrupt is ended, so that the time interval between the first transit state and the second transit state is the duration of the interrupt, that is, the duration of the satellite transit is the same as the duration of the interrupt.
Referring to fig. 2 again, taking the first level as a high level and the second level as a low level as an example for explanation, the interrupt pin 111a of the communication module 11 gives a high level in t11 to indicate that an interrupt is triggered, that is, to indicate the start of the interrupt, and also to indicate that the satellite is in a first transit state of a transit state, that is, the satellite enters the coverage area of the terrestrial satellite device 10, the satellite establishes a connection with the communication module 11, and the communication module 11 is in a communication state. Next, the interrupt pin 111a gives a high level in t22, indicating that the communication module 11 is in the transmission state; next, the interrupt pin 111a gives a low level again in t21, indicating that the communication module 11 is in the receiving state; next, the interrupt pin 111a gives a high level again in t22, indicating that the communication module 11 is in the transmission state; next, the interrupt pin 111a gives a low level again in t21, indicating that the communication module 11 is in the receiving state; next, the interrupt pin 111a presents a high level in t11, indicating the end of the interrupt, and also indicating that the satellite is in a second transit state of the transit states, i.e. the satellite moves out of the coverage area of the terrestrial satellite device 10, the satellite is disconnected from the communication module 11, and the duration of the satellite transit is equal to the duration of the interrupt.
Referring to fig. 3, fig. 3 is a flowchart illustrating an embodiment of a satellite transit monitoring method according to the present application, and it should be noted that the method is not limited to the flowchart shown in fig. 3 if substantially the same result is obtained. The method for monitoring the satellite transit is applied to the ground satellite equipment in the embodiment, and comprises the following steps:
s1, receiving a query instruction;
and S2, responding to the query instruction, querying the transit state during satellite communication from one interrupt pin, and querying the communication state of the communication module from one interrupt pin after preset time.
It can be understood that, receiving an inquiry command, in response to the inquiry command, inquiring a transit state of the satellite during communication from an interrupt pin 111, for example, the interrupt pin 111a, in the communication module 11 to determine whether the satellite is in the transit state, and inquiring a communication state of the communication module 11 from the interrupt pin 111a after a preset time to determine whether the communication module 11 is in the communication state or in a receiving state or a sending state of the communication state, where the preset time may be set according to an actual use requirement, and is not particularly limited.
For example, the preset time is 1 second, after receiving the query instruction, the interrupt pin 111a of the communication module 11 further triggers to generate an interrupt through an interrupt signal triggered by a high level or a low level, queries the transit state of the satellite from the interrupt pin 111a, configures the interrupt pin 111a to represent the transit state of the satellite through a preset level rule, and further queries to obtain the transit start state or the transit end state of the satellite by analyzing the level given by the interrupt pin 111 a. If the satellite is in the transit starting state, after 1 second, the communication state of the communication module 11 is queried from the interrupt pin 111a, the interrupt pin 111a is configured to represent the communication state of the communication module 11 through a preset level rule, and then the communication module 11 in the transmitting state or the receiving state can be queried and obtained by analyzing the level given by the interrupt pin 111 a. By setting an interrupt pin 111a and distinguishing the transit state during satellite communication and the communication state of the communication module through logic judgment, the cost can be reduced, and the software processing efficiency can be improved.
As described above, in response to the query instruction, the transit state at the time of satellite communication is queried from the interrupt pin 111a, and the communication state of the communication module is queried from the interrupt pin 111a after a preset time. In one embodiment of the present application, the polling command includes an interrupt triggered by a first level or a second level.
The first level and the second level may be set to a high level or a low level, for example, the first level is set to a high level, and the second level is set to a low level; alternatively, the first level is set to a low level and the second level is set to a high level, wherein the polling command comprises an interrupt triggered by the first level or the second level.
Taking the first level as the high level, the first level triggers the interrupt, and the preset time is 1 second as an example, after receiving the query instruction, an interrupt pin 111a of the communication module 11 triggers an interrupt by giving an interrupt signal triggered by the instant high level, and further, queries the transit state of the satellite from the interrupt pin 111 a. If the satellite is in the transit-start state, it is queried from the interrupt pin 111a that the communication module 11 is in the transmission state or the reception state after 1 second.
