Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent remote sensing satellites, and in particular to a fault diagnosis and processing method and device for a Beidou short message system. BACKGROUND

[0002] Forests are the largest, most complex and most diverse ecological systems on land, and their safety directly affects the ecological balance of nature. However, in recent years, forest fires have occurred frequently, and due to their suddenness, destructiveness and difficulty in disposal and rescue, forest fires not only cause huge economic losses and environmental impact, but also threaten the lives of animals, plants and even humans.

[0003] In order to effectively detect ground fires and crown fires in forest fires, a fire point detection system can be carried on a land ecosystem carbon monitoring satellite (CM-1). Generally, the fire point detection system is composed of a controller, a fire point detection sensor and a Beidou short message system. Among them, the controller calculates the longitude and latitude position information of the fire point according to the orbit, attitude and fire point position vector of the CM-1 satellite, and returns it to the fire point detection sensor. The fire point detection sensor timely sends the fire point information to the Beidou GEO satellite through the driving of the Beidou short message system, and the Beidou GEO satellite transmits the fire point information to the ground terminal, guiding the emergency management departments such as forest fire fighting to timely dispose. As can be seen, the stable operation of the Beidou short message system is the key to ensure the effective transmission of fire point information. Once the Beidou short message system fails, the fire transmission will fail, causing serious consequences.

[0004] Therefore, there is an urgent need for a fault diagnosis and processing method and device for a Beidou short message system to solve the above technical problems. SUMMARY

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] As previously mentioned, the stable operation of the BeiDou short message system is crucial for ensuring the effective transmission of fire information. However, related technologies do not address how to promptly detect faults in the BeiDou short message system during operation, posing a risk of fire transmission failure. Based on this, the inventors propose a fault diagnosis and handling method and apparatus for the BeiDou short message system, which can promptly detect and handle faults in the BeiDou short message system, improving its reliability.

[0042] The specific implementation of the above concept is described below.

[0043] Please refer to Figure 1 This invention provides a fault diagnosis and handling method for the BeiDou short message system, applied to the host computer of a fire detection system mounted on a satellite. The fire detection system includes a fire detector and a BeiDou short message system. The fire detector is electrically connected to the BeiDou short message system, which is used to communicate with external GEO satellites. The method includes:

[0044] Step 100, every preset period, the first state and the second state of the Beidou short message system are acquired, and the first state and the second state are determined by the first instruction and the second instruction sent by the fire point detector based on the Beidou short message system; wherein the first instruction includes the beam state of the GEO satellite, and the second instruction is determined based on the preset instruction sent by the fire point detector to the Beidou short message system.

[0045] Step 102, based on the duration of the acquired first state and second state, whether the Beidou short message system is faulty and the fault type of the corresponding fault are determined.

[0046] Step 104, if yes, the corresponding processing measures are determined based on the fault type of the fault.

[0047] In the embodiment of the application, first, every preset period, the first state and the second state of the Beidou short message system are acquired, and whether the Beidou short message system is running well in each preset period is determined through the first state and the second state. Then, whether the Beidou short message system is faulty and the fault type of the corresponding fault are determined according to the duration of the first state and the second state (that is, according to the length of the continuous poor running time of the Beidou short message system in multiple preset periods), that is, if the continuous poor running time exceeds the preset value, the system is determined to be faulty and the corresponding fault type is determined, otherwise, the system is determined to be normal. Finally, the corresponding processing measures are determined according to different fault types to quickly solve the problem. As can be seen, the method provided by the application can timely discover and handle the fault of the Beidou short message system, and improve the reliability of the Beidou short message system.

[0048] It should be noted that the upper computer can be separately provided for the fire point detection system, or can share the upper computer of the satellite with the satellite carrying the fire point detection system, as long as there is corresponding computing power.

[0049] The execution mode of each step is described below. Figure 1

[0050] First, for step 100, every preset period, the first state and the second state of the Beidou short message system are acquired, and the first state and the second state are determined by the first instruction and the second instruction sent by the fire point detector based on the Beidou short message system; wherein the first instruction includes the beam state of the GEO satellite, and the second instruction is determined based on the preset instruction sent by the fire point detector to the Beidou short message system.

[0051] The first instruction and the second instruction are introduced below.

[0052] ​For the first instruction, the first instruction is a self-check instruction, which is used to represent whether the Beidou short message system is in normal communication with the Beidou GEO satellite. In operation, the fire point detector transmits the fire information to the GEO satellite through the Beidou short message system, so as to transmit the fire information to the ground terminal device by using the GEO satellite. At the same time, the GEO satellite can also transmit its beam state to the fire point detector through the Beidou short message system, so as to determine whether the GEO satellite correctly receives the fire information. As can be seen, the abnormality of the first instruction will directly lead to the failure of information transmission. In some embodiments, the first instruction is a periodic instruction, and the periodic sending frequency can be 1HZ, etc.

[0053] In some embodiments, the instruction format of the first instruction can be as shown in Table 1:

[0054] Table 1: First instruction format table

[0055]

[0056]

[0057] For the second instruction, the second instruction is a feedback information instruction, that is, a non-periodic instruction sent by the Beidou short message system to the fire point detector after receiving the preset instruction sent by the fire point detector. The second instruction is used to represent whether the Beidou short message system itself has an abnormality.

[0058] In some embodiments, the instruction format of the second instruction can be as shown in Table 2:

[0059] Table 2: Second instruction format table

[0060]

[0061]

[0062] The determination method of the first state and the second state will be described in detail below.

[0063] In some embodiments, the first state includes a first healthy state and a first fault state;

[0064] The first state is determined by the following method:

[0065] If the fire point detector does not receive the first instruction sent by the Beidou short message system within the first preset time, and / or the first instruction sent by the Beidou short message system received by the fire point detector within the first preset time all has a checksum error, it is determined that the first state is the first fault state; otherwise, it is determined that the first state is the first healthy state.

[0066] As before, the first instruction is a periodic instruction, such as a periodic sending frequency can be 1HZ, at this time, the first preset time can be 3 seconds, that is, if the fire point detector does not receive the first instruction for more than 3 seconds, or although the first instruction is received within 3 seconds, but the checksum of the instruction is wrong, it can be considered that the communication between the Beidou short message system and the GEO satellite fails. Of course, the first preset time can also be selected as other values, which are not limited in the present application. In addition, the first state can be stored in the telemetry package of the upper computer, and the upper computer can obtain the first state of the Beidou short message system through the telemetry package. In addition, when the first state is determined to be the first fault state, the first state in the telemetry package can be set to 1 (abnormal), and vice versa, the first state in the telemetry package can be set to 0 (normal).

[0067] In some embodiments, the second state includes a second healthy state and a second fault state;

[0068] The second state is determined by the following way:

[0069] S1, in response to the fire point detector sending a preset instruction to the Beidou short message system, if the fire point detector does not receive the second instruction sent by the Beidou short message system for more than a second preset time, it is determined that the second state is a second fault state;

[0070] S2, in response to the fire point detector receiving the second instruction within the second preset time, it is determined whether the checksum of the second instruction is correct, if not, it is determined that the second state is a second fault state and the second instruction checksum error, otherwise, step S3 is executed;

[0071] S3, it is determined whether the second instruction is executed successfully, if not, it is determined that the second state is a second fault state, otherwise, it is determined that the second state is a second healthy state.

[0072] In this step, the second preset time can be 1 second, that is, when the fire point detector sends a preset instruction to the Beidou short message system, if the fire point detector does not receive the second instruction sent by the Beidou short message system for more than 1 second, it is determined that the second state is a second fault state. Of course, the second preset time can also be selected as other values, which are not limited in the present application. In addition, the second state can also be stored in the telemetry package of the upper computer, and the upper computer can obtain the second state of the Beidou short message system through the telemetry package. In addition, when the second state is determined to be the second fault state, the second state in the telemetry package can be set to 1 (abnormal), and vice versa, the second state in the telemetry package can be set to 0 (normal). In addition, when the checksum of the second instruction is wrong, the "instruction checksum" of the second state in the telemetry package can be set to 1 (i.e. checksum error), and vice versa, the "instruction checksum" of the second state in the telemetry package can be set to 0 (i.e. checksum correct).

[0073] It should be noted that the user can set the content of the second instruction according to actual needs, as shown in Table 2, and the code for setting the instruction execution status in W11 is Y / N, wherein Y represents successful execution of the instruction, corresponding to character 0x59; N represents failed execution of the instruction, corresponding to character 0x4E. Then, when the character of the W11 bit in the sent second instruction is 0x59, it is determined that the instruction is successfully executed, and otherwise, it is determined that the instruction is not successfully executed. The determination methods of other instruction items are the same as above, and will not be described here.

[0074] In some embodiments, the reason for unsuccessful execution of the second instruction includes frequency setting error and inhibition type indication error; when it is determined that the second instruction is not successfully executed, the fire point detector is further configured to execute:

[0075] determine whether the frequency setting is correct, if not, determine that the frequency setting is incorrect, and otherwise, determine that the frequency setting is correct; and

[0076] determine whether the inhibition type indication is correct, if not, determine that the inhibition type indication is incorrect, and otherwise, determine that the inhibition type indication is correct.

[0077] In this embodiment, as shown in Table 2, when W13 is 0x59, it indicates that the frequency setting is correct, and when it is 0x4E, it indicates that the frequency setting is abnormal. The inhibition type indication includes: 0-transmission inhibition release, 1-received system inhibition instruction, transmission inhibited, 4-beam error or loss of lock, transmission inhibited, 5-input instruction checksum error, and 6-input instruction parameter error. In this embodiment, only when the inhibition type indication is “0-transmission inhibition release”, it is determined that the inhibition type indication is correct, otherwise it is determined that the inhibition type indication is incorrect. Of course, the user can also determine the judgment standard according to the actual situation, and the present application is not limited thereto. In addition, 1) when the frequency setting of the second instruction is incorrect, the “frequency setting” of the second state in the telemetry packet can be set to 1 (i.e. frequency setting error), and otherwise, the “frequency setting” of the second state in the telemetry packet is set to 0 (i.e. frequency setting is correct). 2) When the inhibition type indication of the second instruction is incorrect, the “inhibition type indication” of the second state in the telemetry packet can be set to 1 (i.e. inhibition type indication error), and otherwise, the “inhibition type indication” of the second state in the telemetry packet is set to 0 (i.e. inhibition type indication is correct).

[0078] Next, for step 102, based on the duration of the first state and the second state obtained, it is determined whether the Beidou short message system is faulty and the fault type of the corresponding fault, including:

[0079] determine whether the duration of the first fault state exceeds the third preset time, if yes, determine that the Beidou short message system is faulty and the fault type is the first instruction communication abnormality;

[0080] determining whether the duration of the second fault state exceeds the fourth preset time, if yes, determining that the Beidou short message system is faulty and the fault type is the second instruction communication abnormality;

[0081] if the duration of the first fault state does not exceed the third preset time and the duration of the second fault state does not exceed the fourth preset time, determining that the Beidou short message system is not faulty.

[0082] In this step, 1) since the first instruction abnormality directly leads to the failure of fire point data output, which has a greater impact on the system, the third preset time can be 5 seconds. That is, if the Beidou short message system is in the first fault state for 5 seconds continuously in multiple preset periods, it is determined that the Beidou short message system is faulty and the fault type is the first instruction communication abnormality. If the first state of the Beidou short message system in multiple preset periods is continuously in the first healthy state or alternately in the first healthy state and the first fault state, it can be determined that the Beidou short message system is not faulty. 2) Compared with the first instruction, the second instruction fault has a smaller impact on the system, so the Beidou short message system can be allowed to have occasional instructions not executed, so the fourth preset time can be 10 seconds. That is, if the Beidou short message system is in the second fault state for 10 seconds continuously in multiple preset periods, it is determined that the Beidou short message system is faulty and the fault type is the second instruction communication abnormality. If the second state of the Beidou short message system in multiple preset periods is continuously in the second healthy state or alternately in the second healthy state and the second fault state, it can be determined that the Beidou short message system is not faulty. Of course, the third preset time and the fourth preset time can be set by the user according to the requirements of the system, and the present application does not make specific limitations.

[0083] Finally, for step 104, the corresponding processing measures are determined based on the fault type of the fault, including:

[0084] if the fault type of the fault is the first instruction communication abnormality, an instruction to power off the Beidou short message system is sent, and after receiving the fault removal instruction sent by the Beidou short message system, an instruction to power on the Beidou short message system is sent; and

[0085] if the fault type of the fault is the second instruction communication abnormality, an instruction to power off the Beidou short message system is sent, and an instruction to power on the Beidou short message system is sent after a preset time interval.

[0086] In this step, the upper computer sends different instructions for different fault types. If the first instruction is abnormal, the instruction is sent to the Beidou short message system to power off. After power off, the user can analyze the fault cause of the Beidou short message system and handle the fault. After the fault is eliminated, the fault release instruction is sent to the upper computer. After receiving the instruction, the upper computer sends the instruction to the Beidou short message system to power on, and the system resumes operation. If the second instruction is abnormal, the instruction is also sent to the Beidou short message system to power off. Usually, this fault can be solved by restarting the Beidou short message system. Therefore, the instruction to power on the Beidou short message system can be sent after a preset time interval (such as 2 seconds), and the system resumes operation.

[0087] As shown in Figure 2 , Figure 3 , the embodiment of the application provides a fault diagnosis and processing device of a Beidou short message system.

[0098] S2, in response to the fire point detector receiving the second instruction within the second preset time, it is determined whether the checksum of the second instruction is correct, if not, it is determined that the second state is the second fault state and the second instruction checksum error, otherwise, step S3 is executed.

[0099] S3, it is determined whether the second instruction is executed successfully, if not, it is determined that the second state is the second fault state, otherwise, it is determined that the second state is the second healthy state.
