Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of telemetry equipment, and in particular relates to a missile telemetry system, which is suitable for missile telemetry requirements with time constraints on telemetry data acquisition, storage and / or transmission conditions. Background Art
[0002] During the missile development process, in order to analyze and study the working status of each system on the missile, it is necessary to obtain the key working parameters of each system on the missile; after the missile is successfully developed and mass-produced, it is also necessary to test the status of the product in batch inspection target tests, combat training target tests, and actual combat exercises. Especially when the missile has a flight failure, these data will help to locate the fault as soon as possible and eliminate potential fault hazards.
[0003] At present, missile weapon systems mainly obtain the working parameters of various systems of missiles through missile telemetry systems. In order to fully record the data on the missile, in general, the missile telemetry system starts working to obtain comprehensive and real-time data on the missile after power-on initialization. However, as the application scenarios of missile systems become more and more complex, the elements of combat exercise systems become more and more abundant, and the electromagnetic radiation constraints on various types of equipment become more and more, it is required that the missile telemetry system, especially the radiation sources such as missile-borne telemetry equipment, cannot be in the launch working state all the time, and need to work under the premise of meeting relevant constraints in specific application scenarios.
[0004] The current missile weapon system mainly adopts the method of installing recorders on the missile to solve the above problems. The on-missile recorders will not radiate information to the outside during the entire working process. However, due to the difficulties and problems of on-missile recorders such as heavy recovery tasks, low recovery probability, high instrument damage rate, and putting recovery personnel in a dangerous environment, their application is limited. Summary of the invention
[0005] 1. Technical issues to be resolved
[0006] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the prior art, how to provide a missile telemetry system suitable for telemetry data collection, storage and / or transmission conditions with time constraints.
[0007] Another object of the present invention is to provide a workflow suitable for a missile telemetry system where there are time constraints on telemetry data collection, storage and / or transmission conditions.
[0008] (II) Technical solution
[0009] In order to solve the above technical problems, the present invention provides a missile telemetry system, which comprises: missile-borne telemetry equipment, frequency setting equipment and telemetry ground station;

[0011] The frequency setting device is used to unify the wireless communication working frequency between the missile-borne telemetry equipment and the telemetry ground station;
[0012] The telemetry ground station is used to receive on-board data and decode and process the received on-board data.
[0013] The missile-borne telemetry equipment contains a storage module for storing missile-borne data.
[0014] Among them, the missile-borne telemetry equipment has a launch status control function, which can control the missile-borne telemetry equipment to be in a launch state or a silent state.
[0015] Among them, the missile-borne telemetry equipment can set a default operating frequency. In the event of an abnormal frequency setting, the missile-borne telemetry equipment sends data at the default frequency.
[0016] The missile-borne telemetry equipment is connected to the missile-borne module in a wired mode or a wireless mode or both modes at the same time, and the type of missile-borne data recorded and sent is digital data or analog data or both digital and analog data.
[0017] Among them, the frequency setting device is a non-essential device. When the operating frequency of the missile-borne telemetry equipment and the telemetry ground station adopts the default frequency and does not need to be set, the frequency setting device does not work.
[0018] Among them, the telemetry ground station can set a default working frequency. In the event of an abnormality in the process of determining the working frequency, the telemetry ground station can receive on-board data at the default frequency.
[0019] Wherein, the frequency setting device and the telemetry ground station are connected via wired or wireless means.
[0020] Among them, the frequency setting equipment and the telemetry ground station are used as an integrated device through integrated design.
[0021] The working steps of the missile telemetry system are as follows:
[0022] The missile telemetry system is initialized, and the missile-borne telemetry equipment, the frequency setting equipment and the telemetry ground station are respectively powered on and initialized;
[0023] After the initialization is completed, the missile-borne telemetry equipment and the frequency setting equipment enter the frequency setting communication state, and the frequency setting is completed through the frequency setting information interaction logic. During the process, the frequency setting equipment performs frequency allocation, and the missile-borne telemetry equipment determines the working frequency. After the frequency setting equipment confirms the working frequency, it sends the working frequency to the telemetry ground station. After the telemetry ground station receives the working frequency information, it determines the working frequency; when the above frequency setting communication process is abnormal, the missile-borne telemetry equipment and the telemetry ground station both work at the default frequency; when the missile telemetry system does not need to set the frequency, and the missile-borne telemetry equipment and the telemetry ground station both work at the default frequency, the above frequency setting process can be omitted;
[0024] After the missile-borne telemetry equipment is powered on and initialized, it starts to collect and store the missile-borne data according to the required data collection time. When the required data sending time window is reached, the missile-borne data is sent according to the time window and at the determined working frequency. At the same time, the telemetry ground station enters the working state of receiving the missile-borne data telemetry signal according to the determined working frequency after determining the working frequency. After receiving the missile-borne data, the data is decoded and processed.
[0025] Among them, the frequency setting information interaction logic must fully consider the correctness of the frequency setting, reasonably design the interaction logic and the redundancy of frequency confirmation, improve the reliability of frequency setting, and ensure that the working frequency determined by the missile-borne telemetry equipment is consistent with the working frequency confirmed by the frequency setting equipment under normal and various abnormal conditions.
[0026] Among them, the required data collection time needs to be considered according to the characteristics of the missile weapon system, and the design is based on constraints such as ensuring useful data recording, saving storage space, eliminating invalid data and improving data processing and analysis efficiency.
[0027] Among them, the required data sending time window needs to be considered according to the characteristics of the missile weapon system, and the operational scenario requirements and the electromagnetic radiation window of the weapon system are used as constraints during the design.
[0028] (III) Beneficial effects
[0029] Compared with the prior art, the technical effect of the present invention is that when there are time constraints on the telemetry data collection, storage and / or transmission conditions of the missile telemetry system, by controlling the system data collection time and transmission time, the missile telemetry system can complete the collection of all valid data within the necessary time, and complete the transmission and reception of the collected data within the allowed time window. Compared with the traditional telemetry system, the system can adapt to various usage scenarios by controlling the working state, and has a wider application space. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Example 1
[0053] The missile telemetry system of the present invention comprises: missile-borne telemetry equipment, frequency setting equipment and telemetry ground station, wherein:
[0054] The missile-borne telemetry equipment is connected to the missile onboard module and is used to record the data of the onboard module and can send the data to the outside through wireless communication;
[0055] The frequency setting equipment is used to unify the wireless communication working frequency between the missile-borne telemetry equipment and the telemetry ground station;
[0056] The telemetry ground station is used to receive data on the missile and decode and process the received data.
[0057] The missile telemetry system of the present invention has a missile-borne telemetry device comprising a storage module capable of storing missile-borne data and having a launch state control function, and capable of switching between a launch state and a silent state.
[0058] The missile telemetry system of the present invention can work at a default working frequency, the missile-borne telemetry equipment can send data at the default frequency, and the telemetry ground station can receive data at the default frequency. At this time, the frequency setting equipment can be used as a non-essential equipment.
[0059] A missile telemetry system workflow, the steps are as follows:
[0060] (1) The missile-borne telemetry equipment, frequency setting equipment and telemetry ground station are powered on and initialized;
[0061] (2) The missile-borne telemetry equipment and the frequency setting equipment enter the frequency setting communication state, and complete the frequency setting through the frequency setting information interaction logic. During the process, the frequency setting equipment allocates the frequency. After receiving the working frequency, the missile-borne telemetry equipment feedbacks to the frequency setting equipment. After the frequency setting equipment confirms the feedback working frequency, it sends the working frequency to the telemetry ground station. After receiving the working frequency information, the telemetry ground station feedbacks to the frequency setting equipment and determines the working frequency. When the above frequency setting communication process is abnormal, the missile-borne telemetry equipment and the telemetry ground station can work according to the default frequency. When the working frequency of the missile telemetry system is fixed, the above frequency setting process does not exist in the workflow.
[0062] (3) After the missile-borne telemetry equipment is powered on and initialized, it starts to collect and store the missile-borne data according to the required data collection time. When the required data transmission time window is reached, the missile-borne data is sent according to the time window and at the determined working frequency. At the same time, the telemetry ground station enters the working state of receiving the missile-borne data telemetry signal according to the determined working frequency after determining the working frequency. After receiving the missile-borne data, the data is decoded and processed.
[0063] Example 2
[0064] like Figure 1 The telemetry system shown is suitable for a missile with time constraints on telemetry data collection, storage and / or sending conditions. The telemetry system includes a missile-borne telemetry device, a frequency setting device and a telemetry ground station. The missile-borne telemetry device is connected to the missile module and is used to record the data of the missile module according to the required data collection time, and can send the data to the outside in the required time window through wireless communication. The frequency setting device is used to unify the wireless communication working frequency between the missile-borne telemetry device and the telemetry ground station. The telemetry ground station is used to receive the missile data, and decode and process the received data.
[0065] Example 3
[0066] The workflow of a helicopter-borne air-to-ground missile telemetry system is as follows: Figure 2 , the steps are as follows:
[0067] (1) Before the missile is launched, the frequency setting equipment and telemetry ground station are powered on and initialized. The missile-borne telemetry equipment is initialized after the missile enters the launch process and is powered on.
[0068] (2) After the missile-borne telemetry equipment is initialized, the default frequency is loaded and the communication state is entered after loading. In addition, when the missile-borne telemetry equipment is powered on for 5 seconds and the required data collection time is reached, the missile-borne data collection and storage begins.
[0069] (3) After the frequency setting device is initialized, it starts planning and setting the frequency according to the frequency range of the missile telemetry system and the current frequency occupancy. After the planning is completed, it enters the frequency setting communication state;
[0070] (4) After the telemetry ground station completes initialization, it loads the default frequency point. After loading, it enters the state of receiving the missile data according to the default frequency point, and enters the frequency point setting communication state at the same time;
[0071] (5) The frequency setting device periodically sends a frequency setting pairing command to the missile-borne telemetry device via wireless communication. After receiving the pairing command, the missile-borne telemetry device also sends a pairing response command to the frequency setting device via wireless communication to complete the pairing. After the pairing is completed, the frequency setting device periodically sends a planned frequency setting command to the missile-borne telemetry device. After receiving the frequency setting command, the missile-borne telemetry device determines the working frequency and sends a frequency setting response command to the frequency setting device. After receiving the frequency setting response command from the missile-borne telemetry device, the frequency setting device begins to periodically send the planned frequency setting command, i.e., the working frequency determined by the missile-borne telemetry device, to the telemetry ground station. After receiving the frequency setting command, the telemetry ground station immediately switches from the state of receiving missile-borne data at the default frequency to the state of receiving missile-borne data at the set frequency.
[0072] (6) 10 seconds after the missile-borne telemetry device is powered on, the required data transmission time window is reached. If the frequency setting process in step 5 has been successfully completed at this time, the missile-borne telemetry device starts to send missile-borne data at the set frequency, and the telemetry ground station receives the missile-borne data at the set frequency. If an abnormality occurs and step 5 is not completed at this time, the missile-borne telemetry device immediately exits the frequency setting communication state and starts to send missile-borne data at the default frequency, and the telemetry ground station receives the missile-borne data at the default frequency.
[0073] (7) After the missile flight is completed, the telemetry ground station decodes and processes the received on-board data as required for analysis by relevant personnel.
[0074] In some embodiments, the missile-borne telemetry equipment and the telemetry ground station operate at a determined default frequency, and the entire operation does not require the participation of frequency setting equipment. The missile telemetry system does not include frequency setting equipment.
[0075] It should be noted that the above-mentioned process operations can be applied in combination to different degrees. For the sake of simplicity, the implementation methods of various combinations are not described in detail. Technical personnel in this field can flexibly adjust the order of the above-mentioned operating steps according to actual needs, or flexibly combine the above-mentioned steps.
