Description

Technical Field

[0001] The present invention belongs to the field of space launch test, and in particular relates to a method and device for generating and processing multi-target T0 information of a space launch site. Background Art

[0002] With the continuous development of my country's space launch test technology, the density of test tasks is getting higher and higher. New test modes such as multi-task parallelism and single-task multi-launch aircraft continuous firing have emerged. Space launch sites need to process T0 information of multiple targets concurrently and form T0 information of multiple targets at the same time. The T0 equipment of space launch sites is designed based on single-target launch tasks. The T0 equipment itself cannot effectively distinguish targets. To generate multi-target T0 information, multiple T0 equipment must cooperate with each other to achieve it. The same T0 equipment may undertake the T0 information triggering task of multiple targets. At the same time, each target must consider the backup of T0 equipment to ensure the reliability of T0 information triggering. This greatly increases the complexity of T0 information generation and processing. It is necessary to realize the reliable generation of multi-target T0 information by single-target T0 generation equipment, and it is necessary to design a general and reasonable processing model in real-time data processing to adapt to the T0 information processing requirements under different test modes.

[0003] T0 devices cannot effectively distinguish targets in their output information, and multi-target T0 information generated by a single T0 device can only be distinguished by the T0 generation sequence. Multiple T0 devices can generate T0 information for different targets, or they can generate T0 information for the same target in backup. Comprehensive analysis of the use of T0 devices in current single-target and multi-target space launch missions shows that there are traditionally two main T0 information triggering modes: (1) Sequential T0 information trigger mode. A single T0 device generates all target T0 information in sequence, and each T0 device backs up each other. In this mode, all target takeoff signal lines are connected to the T0 device, and each target takes off in the agreed order, triggering the T0 device to form each target T0 information. The T0 devices back up each other, such as Figure 1 shown.

[0004] This mode is easy to implement and T0 information judgment is relatively easy; however, at present, after the T0 device at the space launch site triggers T0, it is generally necessary to keep sending T0 information for more than 10 seconds to ensure that T0 is reliably judged, and a certain amount of time must be left for the T0 device to recover. Therefore, this mode is not suitable for the test mode of short-term continuous launch of multiple targets. It can only be used in missions with long launch intervals to ensure the status recovery of the T0 device between the takeoffs of each target and the effective judgment of the target T0 information.

[0005] (2) Single T0 information trigger mode. A single T0 device generates a target T0 information, and multiple T0 devices jointly generate all target T0 information. In this mode, one T0 device or several T0 devices form a target T0 information, and multiple T0 devices form a backup, such as Figure 2 shown.

[0006] In this mode, the judgment of T0 information is easy to achieve, but more T0 equipment is required. Currently, there are only a few sets of T0 equipment in the space launch site. Therefore, this mode has a large limit on the number of aircraft launched continuously and is only suitable for the situation of continuous launch of a small number of aircraft. The specific situation depends on the number of T0 equipment in the space launch site. At the same time, when T0 equipment is limited, the lack of effective backup of each target T0 equipment will reduce the reliability of the test mission, making the triggering of T0 information a weak link in the test mission.

[0007] Since the relationship between the T0 device and the target is fixed in the traditional T0 information trigger mode, the traditional T0 information processing method does not need to adapt to the T0 device failure situation, nor does it consider the adjustment of the target T0 information. The processing method is simple and only meets the single-target T0 information processing needs. Summary of the invention

[0008] The technical problem to be solved by the present invention is to improve the reliability of T0 information generation of each target and reduce the complexity of T0 information processing under the conditions of limited T0 equipment and continuous or simultaneous launch of multiple targets. A method and device for generating and processing T0 information of multiple targets at a space launch site are proposed.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is: A method for generating T0 information of multiple targets in a space launch site, wherein a single T0 device sequentially triggers the T0 information of a part of the targets, and multiple T0 devices jointly and mutually back up to trigger the T0 information of all the targets; the joint and mutual back up means that the T0 information of one target is triggered by two or more T0 devices, and the T0 information triggered by the two or more T0 devices backs up each other; When the T0 device triggers the T0 information, each T0 device triggers the T0 information at intervals, and multiple joint and mutually backed-up T0 devices configured for each target use the earliest T0 information as the T0 information of the corresponding target according to the timing relationship.

[0010] The present invention also provides a multi-target T0 information processing device for a space launch site, which pre-sets a two-dimensional corresponding relationship matrix of target devices between each T0 device and the target corresponding to the T0 information sequentially triggered by each T0 device, and includes the following modules: T0 information receiving module: used to receive T0 information triggered by each T0 device; T0 information distribution module: used to determine which T0 device the T0 information comes from according to the source identifier in the T0 information and transmit it to the corresponding T0 device T0 information judgment processing module; T0 information judgment processing module: used to enable each T0 device to store the received T0 information in the T0 information queue of the corresponding T0 device in chronological order. Each T0 device corresponds to a T0 information judgment processing module and a T0 information queue; Target device timing correspondence module: used to find the two-dimensional correspondence matrix of the target device and obtain the correspondence of <target, T0 device, T0 timing>. The T0 timing is the time series value when the T0 device stores the received T0 information in the T0 information queue in chronological order; T0 timing acquisition module: used to obtain the T0 device sequence that triggers the T0 information of the current target to be taken off according to the two-dimensional correspondence matrix of the target device, and use the target device timing correspondence module to obtain the T0 timing of the T0 information of the current target to be taken off in the T0 information queue of each T0 device in the T0 device sequence; Multi-target T0 information formation module: used to obtain the T0 timing in the T0 information queue of each T0 device in the T0 device sequence that triggers the T0 information of the current target to take off according to the T0 timing acquisition module, take the T0 information with the earliest timing as the T0 information of the current target to take off, and put the T0 information of the target into the multi-target T0 queue.

[0011] Furthermore, the T0 information judgment processing module also includes a T0 information validity judgment module, which is used to judge the validity of the T0 information before storing the received T0 information in the T0 information queue of the corresponding T0 device. Only valid T0 information is stored in the T0 information queue of the corresponding T0 device.

[0012] Furthermore, the method for judging the validity of T0 information is: use the M-to-N principle, where M>N, N>M / 2, M refers to the number of data frames of T0 information. If the received T0 information has M frames of data and N frames are consistent, then the T0 information is judged to be valid.

[0013] The present invention also provides a space launch site multi-target T0 information processing method, using a space launch site multi-target T0 information processing device, including the following steps: Step 1: The T0 information receiving module receives the T0 information triggered by each T0 device; Step 2: The T0 information distribution module determines which T0 device the T0 information comes from based on the source identifier in the T0 information and transmits it to the T0 information judgment processing module of the corresponding T0 device; Step 3: Each T0 device stores the received T0 information in the T0 information queue of the corresponding T0 device in chronological order; Step 4: Find the two-dimensional correspondence matrix of the target device, and obtain the correspondence of <target, T0 device, T0 timing> according to the T0 timing in the T0 information queue. The T0 timing refers to the time series value of receiving T0 information in time sequence and stored in the T0 information queue corresponding to the T0 device; Step 5: Obtain the T0 device sequence that triggers the T0 information of the current target to be taken off according to the two-dimensional correspondence matrix of the target device, and obtain the T0 timing of the T0 information of the current target to be taken off in the T0 information queue of each T0 device in the T0 device sequence according to step 4; Step 6: According to the T0 timing acquisition module, obtain the T0 timing in the T0 information queue of each T0 device in the T0 device sequence that triggers the T0 information of the current target to take off, take the T0 information with the earliest timing as the T0 information of the current target to take off, and put the T0 information of the target into the multi-target T0 queue.

[0014] Furthermore, in step 3, before storing the received T0 information in the T0 information queue of the corresponding T0 device, the validity of the T0 information needs to be judged, and only valid T0 information is stored in the T0 information queue of the corresponding T0 device.

[0015] Furthermore, the method for judging the validity of T0 information is: use the M-to-N principle, where M>N, N>M / 2, M refers to the number of data frames of T0 information. If the received T0 information has M frames of data and N frames are consistent, then the T0 information is judged to be valid.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects: The present invention provides a method and device for generating and processing multi-target T0 information at a space launch site. Through the multi-target T0 information generating method, a single T0 device sequentially triggers the T0 information of some targets, and multiple T0 devices jointly trigger the T0 information of all targets in a backup manner, so that one T0 device triggers the T0 information of multiple targets, and the T0 information of one target can be triggered by more than two T0 devices, thus achieving backup and solving the reliability problem. At the same time, considering the T0 information sending time and device recovery time of the T0 device, when the T0 device triggers the T0 information, each T0 device triggers the T0 information at intervals, ensuring the normal triggering and continuous triggering of the T0 information. By pre-establishing the correspondence between the T0 device and the multiple targets,<G、T> A two-dimensional description model is proposed, and a multi-target T0 information processing method based on the model is given. According to the two dimensions of target T0 device processing and T0 information timing judgment, the complexity of multi-target T0 information processing is reduced, which not only meets the T0 information processing requirements of traditional T0 information generation methods, but also adapts to the T0 information processing requirements of multi-target T0 information generation methods.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1 Figure 3 A schematic diagram of a method for generating T0 information of multiple targets in a space launch site according to the present invention is shown, in which a single T0 device sequentially triggers the T0 information of some targets for continuous shooting, and multiple T0 devices jointly and mutually back up to trigger the T0 information of all targets; the joint and mutual backup means that the T0 information of one target is triggered by two or more T0 devices, and the T0 information triggered by these two or more T0 devices backs up each other; When the T0 device triggers the T0 information, each T0 device triggers the T0 information at intervals, and multiple joint and mutually backed-up T0 devices configured for each target use the earliest T0 information as the T0 information of the corresponding target according to the timing relationship.

[0020] In view of the need for reliable triggering of multi-target T0 information, this embodiment provides a method for generating multi-target T0 information, namely, a mixed T0 information triggering mode. This triggering mode enables a single T0 device to sequentially trigger the T0 information of some targets, and multiple T0 devices jointly trigger the T0 information of all targets. In this mode, one T0 device can trigger the T0 information of multiple targets, and the T0 information of one target can be triggered by two or more T0 devices. Considering the T0 information sending time and device recovery time of the T0 device, each T0 device triggers the T0 information at intervals. While ensuring the normal triggering of the T0 information, the backup of the T0 device is taken into account. In this mode, the T0 information is triggered as follows: Figure 3If there are 4 sets of T0 equipment at the space launch site, it can ensure the continuous firing mission of multiple aircraft at a certain interval, and each target has two sets of T0 equipment to trigger T0 information, which can effectively ensure the reliability of T0 information triggering. Figure 3 The description is a mixed T0 information trigger mode under 4 sets of T0 devices. If the interval between continuous firing is short or some aircraft are firing at the same time, more T0 devices are required to cooperate with each other to complete the T0 information trigger task. The mixed T0 information trigger mode of this embodiment not only meets the traditional single-target T0 information triggering requirements, but also adapts to the new multi-target T0 information triggering requirements.

[0021] According to a comprehensive analysis of the sequential T0 information trigger mode, the single T0 information trigger mode and the hybrid T0 information trigger mode of the present application, in a multi-target continuous shooting task, no matter which T0 information trigger mode is used, for each T0 device, it can be regarded as sequentially triggering the T0 information of one or more targets, and the order will not be disordered; for multiple T0 devices, there will be a backup relationship between them, that is, the T0 information of a target may be triggered by multiple T0 devices. According to the T0 information processing principle, the T0 information with the earliest timing is used as the T0 information of the corresponding target. Therefore, the correspondence between the T0 device and the multi-target T0 information can be regarded as a two-dimensional matrix. One dimension of the matrix is ​​used to identify the T0 device (T0 Generator), represented by G; the other dimension is used to identify the target (Target) corresponding to the T0 information sequentially triggered by each T0 device, represented by T. The correspondence between the T0 device and the target can be expressed by<G、T> The two-dimensional matrix is ​​described as shown in the following table.

[0022]

[0023] Slave device target two-dimensional relationship correspondence matrix<G、T> The rows can be used to determine which targets a T0 device triggers T0 information in sequence, and the columns can be used to determine which T0 devices trigger each target T0 information. Therefore, the two-dimensional relationship between the device and the target corresponds to the matrix<G、T> The corresponding relationship among <target, T0 device, T0 timing> can be obtained.

[0024] Embodiment 2 The present invention also provides a multi-target T0 information processing device for a space launch site, which pre-sets a two-dimensional corresponding relationship matrix of target devices between each T0 device and the target corresponding to the T0 information sequentially triggered by each T0 device, and includes the following modules: T0 information receiving module: used to receive T0 information triggered by each T0 device. T0 information frames are generally stored in the cache queue after being received.

[0025] T0 information distribution module: used to determine which T0 device the T0 information comes from based on the source identifier in the T0 information and pass it to the T0 information judgment processing module of the corresponding T0 device. The T0 information contains a source identifier, which can tell which T0 device the T0 information comes from, and then the T0 information from the T0 device is redistributed to the T0 information judgment processing module of the corresponding T0 device.

[0026] T0 information judgment processing module: used to enable each T0 device to store the received T0 information in the T0 information queue of the corresponding T0 device in chronological order, and each T0 device corresponds to a T0 information judgment processing module and a T0 information queue. In this embodiment, the T0 information judgment processing module also includes a T0 information validity judgment module, which is used to judge the validity of the T0 information before storing the received T0 information in the T0 information queue of the corresponding T0 device. Only valid T0 information is stored in the T0 information queue of the corresponding T0 device. The method for judging the validity of T0 information is: use the principle of M judging N, where M>N, N>M / 2, M refers to the number of data frames of T0 information, if the received T0 information has M frames of data, and N frames of data are consistent, then the T0 information is judged to be valid.

[0027] Target device timing correspondence module: used to find the two-dimensional correspondence matrix of the target device and obtain the correspondence of <target, T0 device, T0 timing>. The T0 timing is the time series value when the T0 device stores the received T0 information in the T0 information queue in chronological order.

[0028] T0 timing acquisition module: used to obtain the T0 device sequence that triggers the T0 information of the current target to be taken off according to the two-dimensional correspondence matrix of the target device, and use the target device timing correspondence module to obtain the T0 timing of the T0 information of the current target to be taken off in the T0 information queue of each T0 device in the T0 device sequence. In this embodiment, Figure 5 As shown in the figure, assuming that the current target to be taken off is target 1, then<G,T> It can be seen from the corresponding matrix that the T0 device sequence corresponding to target 1 is device 1, device 2 and device M, so the T0 timing of the T0 information is found from the T0 information queues of device 1, device 2 and device M respectively.

[0029] Multi-target T0 information formation module: Use the target device timing correspondence module to obtain the T0 timing of the T0 information of the current target to be taken off in the T0 information queue of each T0 device in the T0 device sequence. If the T0 information of the corresponding T0 timing of multiple T0 devices corresponding to the same target are all valid, the T0 information with the earlier T0 timing is determined to form the T0 information of the target, and the T0 information of the target is placed in the multi-target T0 queue.

[0030] Embodiment 3 The second embodiment mainly processes the multi-target T0 information generated by the first embodiment, thereby realizing the launch mission for multiple targets.

[0031] Figure 4 A method for processing multi-target T0 information of a space launch site is shown. A multi-target T0 information processing device of a space launch site is used. When processing the multi-target T0 information, the method includes the following steps: Step 1: The T0 information receiving module receives the T0 information triggered by each T0 device.

[0032] Step 2: The T0 information distribution module determines which T0 device the T0 information comes from based on the source identifier in the T0 information and transmits it to the T0 information judgment processing module of the corresponding T0 device.

[0033] Step 3: Each T0 device stores the received T0 information in the T0 information queue of the corresponding T0 device in chronological order. In this embodiment, before storing the received T0 information in the T0 information queue of the corresponding T0 device, the validity of the T0 information needs to be judged, and only valid T0 information is stored in the T0 information queue of the corresponding T0 device.

[0034] In this embodiment, the method for determining the validity of T0 information is: use the M-to-N principle, where M>N, N>M / 2, and M refers to the number of data frames of T0 information. If the received T0 information has M frames of data and N frames of data are consistent, then the T0 information is determined to be valid.

[0035] In this embodiment, in the T0 information queue of each T0 device, valid T0 information is stored in the queue position of the corresponding time sequence according to the time sequence order.

[0036] Step 4: Find the two-dimensional correspondence matrix of the target device, and obtain the correspondence of <target, T0 device, T0 timing> according to the T0 timing in the T0 information queue. The T0 timing refers to the time series value that receives the T0 information in chronological order and stores it in the T0 information queue corresponding to the T0 device.

[0037] Step 5: Obtain the T0 device sequence that triggers the T0 information of the current target to be taken off according to the two-dimensional correspondence matrix of the target device, and obtain the T0 timing of the T0 information of the current target to be taken off in the T0 information queue of each T0 device in the T0 device sequence according to step 4; Step 6: According to the T0 timing acquisition module, obtain the T0 timing in the T0 information queue of each T0 device in the T0 device sequence that triggers the T0 information of the current target to take off, take the T0 information with the earliest timing as the T0 information of the current target to take off, and put the T0 information of the target into the multi-target T0 queue.

[0038] like Figure 6 The two-dimensional schematic diagram of the multi-target T0 information processing model shown divides the entire processing process into two dimensions: processing of target T0 devices and timing decision processing of T0 information of T0 devices. First, T0 information is assigned to the T0 information decision processing module of each T0 device for timing T0 decision processing, and then target T0 information processing is performed, that is, the two dimensions are performed sequentially.

[0039] Experimental verification 1. Implementation of multi-target T0 information processing In order to facilitate the implementation of the program, an object-oriented programming method is adopted, which is divided into two categories: target T0 device processing and T0 device T0 information judgment processing, which correspond to the two dimensions of target T0 device processing and T0 information timing judgment processing of the T0 device itself. After the T0 information judgment processing class of the T0 device itself completes the T0 information judgment based on the timing, it forms a T0 information judgment result queue and provides an interface for the target T0 device processing class to call; the target T0 device processing class completes the formation and processing of multi-target T0 information. At the same time, for the convenience of implementation, the T0 information allocation function is also completed by the target T0 device processing class.<G、T> The matrix is ​​described by a two-dimensional matrix and implemented by a variable of the target T0 device processing class.

[0040] During the launch process, the launch of several targets in the continuous firing mission may be temporarily canceled. Therefore, the judgment processing class of the T0 information of the T0 device itself needs to provide the function of temporarily canceling the T0 information judgment of a certain timing; at the same time, it needs to provide the function of restoring the T0 information judgment of the timing, and put the T0 back into the timing judgment queue to cope with the situation of re-launching after the aircraft fails.

[0041] In order to deal with the situation where the aircraft takeoff signal line is connected incorrectly or the takeoff of one aircraft affects the T0 signal triggering of other aircraft, the T0 device processing class needs to form a T0 list of all received T0 information and be able to switch between targets. It not only provides an interface to the outside world, but also can assign any T0 information in the list to a certain target, and has the ability to reset the T0 information of any target. This function can be achieved by operating the multi-target T0 queue. The collaborative relationship between objects is as follows Figure 7 As shown, the objects of the T0DeviceManager class and the T0Generator class cooperate with each other to complete the data processing functions of the two dimensions of multi-target T0 information processing.

[0042] 2. Multi-target T0 information processing test verification Simulation software is used to generate multi-target T0 information, and the correctness, real-time performance and reliability of the processing model are tested and verified. The simulation of T0 information can be regarded as the reverse process of T0 information processing.

[0043] During the T0 information simulation process, according to the triggering relationship between the T0 device and each target T0, each T0 device simulator is triggered in turn to simulate the T0 information, and sent to the T0 device simulator T0 information cache queue, and sent to the T0 information processing device through the network. The correctness of the T0 information processing is observed from the multi-target T0 queue generated by the multi-target T0 information processing module, and time stakes are inserted at the front and back ends of the program codes of key processing modules such as T0 information judgment processing and multi-target T0 information formation to obtain the T0 information processing delay.

[0044] During the test, the focus was on testing the delays in two dimensions of T0 information processing, namely the T0Generator class and the fun_Process_T0() function of the T0DeviceManager class. To ensure the accuracy of the delay test, each processing module was tested 1 million times in a loop to obtain the average delay value. The test results are shown in the table below.

[0045] Latency test results

[0046] The multi-target T0 formation process includes the sequential T0 processing of multiple T0 devices, so the target T0 formation delay can be regarded as the delay of the entire T0 information processing process. From the delay test result table, it can be seen that the T0 processing time is very short, the method is highly real-time, and meets the requirements of real-time data processing.

[0047] The triggering and processing of multi-target T0 information is the key to the space launch site's successful response to new test tasks such as multi-task parallelism and single-task multi-launch vehicle continuous firing. It is necessary to design a flexible, universal, concise and efficient processing model to realize multi-target T0 information processing at the space launch site. The present invention analyzes the T0 information triggering process and the current status of T0 equipment at the space launch site, and proposes a new multi-target T0 information triggering mode based on the traditional T0 information triggering mode. It also analyzes the T0 information processing requirements of the three modes and proposes a new and reliable multi-target T0 information processing method, and establishes the corresponding relationship between T0 equipment and multiple targets.<G、T> A two-dimensional description model is proposed, and a multi-target T0 information processing model based on the model is given. The model is divided into two dimensions: target T0 device processing and T0 information timing judgment, which effectively reduces the complexity of multi-target T0 information processing and improves the reliability of processing. The T0 information generation and processing method has been successfully applied in the multi-target real-time data processing system of the space launch site, and the effectiveness of the method has been verified through simulation and space launch site continuous launch missions.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.

The T0 timing refers to the time series value of receiving T0 information in time sequence and stored in the T0 information queue corresponding to the T0 device; Step 5: Obtain the T0 device sequence that triggers the T0 information of the current target to be taken off according to the two-dimensional correspondence matrix of the target device, and obtain the T0 timing of the T0 information of the current target to be taken off in the T0 information queue of each T0 device in the T0 device sequence according to step 4; Step 6: According to the T0 timing acquisition module, obtain the T0 timing in the T0 information queue of each T0 device in the T0 device sequence that triggers the T0 information of the current target to take off, take the T0 information with the earliest timing as the T0 information of the current target to take off, and put the T0 information of the target into the multi-target T0 queue.

6. A method for processing multi-target T0 information of a space launch site according to claim 5, characterized in that: In step 3, before storing the received T0 information in the T0 information queue of the corresponding T0 device, the validity of the T0 information needs to be judged, and only valid T0 information is stored in the T0 information queue of the corresponding T0 device.

7. A method for processing multi-target T0 information of a space launch site according to claim 6, characterized in that: The method for judging the validity of T0 information is: use the M-to-N principle, where M>N, N>M / 2, and M refers to the number of data frames of T0 information. If the received T0 information has M frames of data and N frames are consistent, then the T0 information is judged to be valid.
