Description

Technical Field

[0001] This invention relates to a generalized simulation and training platform for launch and testing processes, belonging to the field of overall electrical design of launch vehicles. Background Technology

[0002] Currently, the primary training method for launch vehicle test and launch personnel is "training through competition," meaning training is conducted during actual missions. However, this method carries the risk of operational errors damaging real equipment, thus affecting the progress of test and launch missions. To avoid this problem, China has also begun designing training systems for conventional launch vehicles, but these are primarily focused on single-machine training and cannot meet the training requirements for the coordinated operation of the entire rocket system; furthermore, the operational complexity and timing requirements of conventional launch vehicles are far lower than those of cryogenic launch vehicles.

[0003] Currently, various launch sites are updating and deploying universal ground-based telemetry, tracking, and command systems, and there is an urgent need to propose a universal simulation and training platform for the telemetry, tracking, and launch process of cryogenic launch vehicles that is compatible with it. Summary of the Invention

[0004] The technical problem solved by this invention is to overcome the shortcomings of the existing technology and propose a generalized test and launch process simulation training platform to realize the construction of training equipment consistent with real test operations, improve the basic quality of personnel, and support the ability to build a more technically advanced test and launch team.

[0005] The technical solution of this invention is:

[0006] A general-purpose test and launch process simulation and training platform, comprising a test and launch control front-end and a test and launch control back-end;

[0007] The measurement and control front end includes a control system front end equivalent, a measurement system front end equivalent, a power measurement and control system front end equivalent, and a front end overall control network system equipment located on the ground, as well as an arrow body equivalent and an arrow-to-ground detachment cable located on the arrow. Among them, the control system front end equivalent, the measurement system front end equivalent, and the power measurement and control system front end equivalent are connected to the front end overall control network system equipment via network cables, and are connected to the arrow-on-arrow equivalent via detachment cables.

[0008] The launch and control backend includes a ground-based control system backend, a measurement system backend, a power control system backend, a backend central control network system equipment, and a process control module deployed on the backend central control network system equipment. This ensures that the test operations and status responses of each equivalent device at the launch and control frontend are consistent with the actual situation, simulating the status of the launch and control equipment during each test phase, launch process, and flight phase, and simulating various fault conditions during the launch and test of the carrier rocket.

[0009] Furthermore, in the measurement, launch, and control front end:

[0010] The front-end equivalent device of the control system interacts with the back-end of the control system through the front-end central control network system equipment to complete the control test of the rocket body equivalent device, and perform emergency launch, power supply voltage adjustment and leakage check.

[0011] The front-end equivalent of the measurement system interacts and communicates with the back-end of the measurement system through the front-end central control network system equipment, and sends and receives on-rocket telemetry and external safety data, and simulates liquid level data.

[0012] The front-end equivalent of the power measurement and control system interacts with the back-end of the power measurement and control system through the front-end central control network system equipment to complete the control of the on-rocket solenoid valve, the acquisition of on-rocket pressure and temperature parameters, and the adjustment of power supply voltage and leakage current detection.

[0013] The on-rocket equivalent unit simulates the on-rocket parameters of the control system, measurement system, and power system, as well as the status of each controlled object. It interacts with the front-end equivalent units of the control system, measurement system, and power measurement and control system through real disconnect cables. Furthermore, the on-rocket equivalent unit has takeoff contacts and disconnect cables, which can simulate the launch and test process.

[0014] The front-end central control network system equipment includes servers and switches, and enables network communication between the control system front-end equivalent, the measurement system front-end equivalent, and the power measurement and control system front-end equivalent via network cables, and sends the data of each equivalent to the back-end central control network system equipment.

[0015] Furthermore, the equivalent units of the front-end measurement and control system are identical to the real product only in appearance and response. That is, the equivalent units are equipped with buttons, switches, knobs, and digital tubes for status and parameter display and analog status adjustment. They are implemented through an integrated general-purpose board that includes button function, indicator light function, digital tube function, and analog quantity acquisition function. The business functions of the front-end equivalent units are implemented through the logic control module deployed at the back end of the measurement and control system, including logic judgment and control command sending.

[0016] Furthermore, the backend master control network system equipment interacts with the frontend master control network system equipment, and the backend master control network system equipment includes a server and a master control network command and control module deployed on the server;

[0017] Based on the test process, the central control network command and control module connects to the backend of the network control system, the backend of the measurement system, and the backend of the power measurement and control system, and sends test process commands to each system backend to complete the centralized management and information communication functions of the test process, achieve the function of sharing system test processes and information, and realize the integrated testing and control of the launch vehicle ground network.

[0018] Furthermore, the logic control module serves as the central hub of the test and launch process simulation platform, controlling the logic display and control of all equivalents at the front end of the test and launch control system, and participating in the interaction between the front-end equivalents of the control system, measurement system, and power test and control system and their corresponding back-ends; the logic control module includes an interaction simulation module, a parsing and forwarding module, an equipment logic control module, and an equipment management module;

[0019] The interactive simulation module interacts with the measurement system backend, power measurement system backend, and control system backend based on the data received by the central control network command and control module, sending status information and data to each backend; it interacts with the on-rocket equivalent, sending status information data to the on-rocket equivalent and receiving control data from the on-rocket equivalent; it receives control data from the process control module; and it interacts with each front-end equivalent, distributing control commands to each equivalent for hardware indication and display, and collecting and storing the status data of each equivalent.

[0020] The parsing and forwarding module parses the received data, processes and encapsulates it according to the type of information, and sends it to the measurement system backend, power measurement system backend, and control system backend according to the requirements of the information source and destination.

[0021] The equipment logic control module is the logic hub of each front-end equivalent unit. Based on the current stage of the testing and transmission process, the status of the front-end and back-end equipment, and the key data of the front-end and back-end, it drives each front-end equivalent unit to send data according to logic in real time. Based on the operation of each equivalent unit and software module, it judges the correctness of its operation logic in the current state. If it is correct, it controls the corresponding equivalent unit to execute the operation response or send the correct data to the back-end. If it is wrong, it feeds back the abnormal status to the corresponding equivalent unit or the back-end.

[0022] The equipment management module monitors the online status of the front-end equivalent device in real time.

[0023] Furthermore, the process control module is the driving module for the test process. It interacts with the logic control module, sending the test process information, i.e. the current process step, to the logic control module for logic control, and receiving feedback from the logic control module on the completion status of the current process step. When the process control module receives the completion status of the current process step, it sends the next process step to the logic control module to drive the overall test process.

[0024] The process control module has the ability to pre-set fault modes. When a fault mode troubleshooting training is required, the corresponding fault code information is entered into the process control module, and the process control module will run the process steps containing the troubleshooting steps. The fault code is sent to the logic control module before the test starts. The logic control module then uses the logic judgment and information sending containing the fault mode to drive the entire troubleshooting process training.

[0025] Furthermore, the backend of the control system includes a backend control console for each position in the command and control hall and a simulation computer. The simulation computer is equipped with a main control module, a virtual display module, and a data processing module.

[0026] The main control module is the core of the measurement and control system, enabling automated control and data interpretation. It controls the back-end control console and the main control module to complete the execution of the control system's measurement and launch process. The simulation computer virtual display module and data processing module receive and interpret data from the front-end equivalent unit of the control system through the front-end central control network system equipment. If an anomaly occurs, it immediately alerts the system and pauses the process. The main control module forwards command commands, feedback commands, and control data through the data processing module, and interacts with the back-end of the measurement system and the back-end of the power measurement and control system through the back-end central control network system equipment.

[0027] The virtual display module receives and displays power information, rocket data, bus leakage test information, and equipment self-test information from the front-end control network system equipment.

[0028] The data processing module forwards the process control instructions between the main control module and the central control network command and control module, and transfers the control system test status information of the main control module to the central control network command and control module as required; at the same time, it displays the test process information and test data information of the main control module; the data processing module also interprets the received timing data, inertial navigation system data, battery voltage, servo mechanism curve, and thrust adjustment simulation parameters of the on-board equivalent device, and generates an interpretation report.

[0029] Furthermore, the measurement system backend includes a measurement system backend equivalent, a measurement system command and control module, a real-time monitoring module, a data processing module, a data storage module, a data interpretation module, and a measurement parameter binding module; the measurement system backend equivalent receives measurement system data sent by the measurement system frontend equivalent and sends the data to the measurement system command and control module, the data processing module, the data storage module, and the data interpretation module;

[0030] The measurement system command and control module is the core of the measurement system for command and control. It sends control commands to the front-end equivalent unit, the back-end equivalent unit, and the on-rocket equivalent unit of the measurement system, and simulates the power-on and power-off control of each equivalent unit.

[0031] The data processing module processes the test data of the front-end equivalent of the measurement system in real time, and stores and sends the processing results to the command and control module of the central control network in real time;

[0032] The data storage module stores measurement data in real time;

[0033] The data interpretation module interprets the voltage and current data processed by the data processing module in real time and immediately alerts the user if any abnormality occurs.

[0034] Furthermore, the backend of the power measurement system includes a power command and control module, a power measurement and control module, and a measurement and control module;

[0035] The power control module is the core of the power measurement and control system, which simulates the power-on and power-off of the front-end equivalent unit of the power measurement and control system and controls the on-board solenoid valves of the on-board equivalent unit. It sends the power-on and power-off commands and the on-board solenoid valve control commands to the on-board equivalent unit through the front-end and back-end central control network system equipment, and forwards the control commands to the back-end of the control system and the back-end of the measurement system.

[0036] The power measurement and control module collects and monitors various state parameters of the front-end equivalent of the power measurement and control system, the opening and closing status of the solenoid valves simulated by the on-rocket equivalent, and the parameters of the on-rocket power system. Abnormal parameters will be immediately alerted.

[0037] The measurement and control module collects and monitors the status parameters of the front-end equivalent and back-end of the measurement system, collects and monitors the status parameters of the on-rocket equipment of the measurement system simulated by the on-rocket equivalent, and transmits them to the back-end of the measurement system.

[0038] Furthermore, the interface design between the various modules in the measurement, launch, and control backend is as follows:

[0039] The data interface design for the logic control module to send data to the front-end equivalent of the control system, the front-end equivalent of the measurement system, the front-end equivalent of the power measurement and control system, and the on-rocket equivalent is as follows: TCP / IP communication is adopted, the interface command is sent in the form of data packets, and the data elements include table number, code, data type, data body, whether it is out of tolerance, and data length. The interface type is interface call.

[0040] The data interface sent from the backend of the control system, the backend of the measurement system, and the backend of the power measurement and control system to the logic control module is designed as follows: TCP / IP communication is used, the interface commands are sent in the form of data packets, and the data elements include table number, code, data type, data body, whether it is out of tolerance, and data length. The interface type is interface call.

[0041] The data interface sent from the process control module to the logic control module is designed to use TCP / IP communication. Interface commands are sent in the form of data packets. Data elements include packet header, message length, message version, message host, message content encoding, time, message type, message sequence number, reserved fields, and packet tail. The interface type is real-time data transmission.

[0042] The advantages of this invention compared to the prior art are:

[0043] This invention, through a logic control module and a process control module, drives each front-end equivalent unit to send data according to logic in real time based on the current stage of the test and launch process, the status of front-end and back-end equipment, and key front-end and back-end data. It also judges the correctness of the operational logic of each equivalent unit and software module in the current state based on their operation, thus realistically reproducing all logical judgments and equipment responses in the test and launch process. These modules simulate all stages of the cryogenic launch vehicle test and launch process, the correct operational logic of each system, and the logical relationships of the test data of each system. They also support troubleshooting simulation exercises under fault conditions, solving the core logic control problem of the current lack of a cryogenic launch vehicle test and launch process simulation exercise platform. This achieves the challenge of full-process simulation test and launch exercises for cryogenic launch vehicles and troubleshooting operations under fault conditions. Attached Figure Description

[0049] This invention proposes a generalized test and launch process simulation platform, including a test and launch control front-end and a test and launch control back-end, such as... Figure 1 As shown, it includes ground-based control system equipment, measurement system equipment, power system equipment, power measurement and control system equipment, and overall control network system equipment; and on-rocket equivalents, arrow-to-ground detachment cables, and several software testing modules. The ground-based equipment simulates the operational functions and status responses of each system, while the on-rocket equipment simulates the functions and interfaces of the on-rocket electrical system equipment, enabling interaction with the ground equipment.

[0050] I. Measurement and Control Front End

[0051] This includes ground-based equivalent units for the control system front end, measurement system front end, power measurement and control system front end, and the overall control network system; and on-rocket equivalent units for the rocket body and the rocket-to-ground detachment cable. The ground-based equipment simulates the test operation functions and status responses of each system, while the on-rocket equivalent unit simulates the functions and interfaces of the on-rocket electrical system equipment, enabling interaction with the ground-based equipment. Specifically:

[0052] The front-end equivalent of the control system simulates the power supply of the rocket-ground equipment, simulates the rocket-ground, and interacts with the back-end of the control system through the front-end central control network system to complete the control and testing of the rocket-mounted equipment; it supports emergency launch and testing functions, power supply voltage adjustment, and leakage current detection.

[0053] The front-end equivalent of the measurement system simulates the rocket and ground, and interacts and communicates with the back-end of the measurement system through the front-end central control network system; it supports on-rocket telemetry, external data transmission and reception, and simulates liquid level data transmission.

[0054] The front-end equivalent of the power measurement and control system simulates the power supply of the rocket and ground equipment. It simulates the rocket and ground and interacts with the back-end of the power measurement and control system through the front-end central control network system to complete the control of the rocket's solenoid valves and the acquisition of parameters such as rocket pressure / temperature; it also supports power supply voltage adjustment and leakage detection.

[0055] The onboard equivalent unit simulates the onboard parameters of the control system, measurement system, and propulsion system, as well as the states of each controlled object. It interacts with the front-end equivalent units of the control system, measurement system, and propulsion control system via a real release cable. Furthermore, the equivalent unit includes takeoff contacts and a release cable, simulating the launch and test process.

[0056] The front-end equipment of the central control network system includes servers and switches. It enables network communication between the front-end equivalents of the control system, measurement system, and power measurement and control system via network cables, and sends the data of the equivalents to the back-end equipment of the central control network system.

[0057] The aforementioned front-end equivalents only need to match the appearance and response of the actual product. That is, the equivalents include devices such as buttons, switches, knobs, and digital displays for status and parameter display and analog status adjustment, implemented through integrated general-purpose boards that include button functions, indicator light functions, digital display functions, and analog quantity acquisition functions. The front-end equivalents' business functions are implemented through a logic control module deployed in the back-end computer, including logic judgment and control command sending.

[0058] II. Measurement and Control Backend

[0059] This includes the ground-based control system backend, measurement system backend, power measurement and control system backend, overall control network system equipment and command and control software, logic control modules, and process control modules. This ensures that the test operations and state responses of each equivalent unit are consistent with reality, simulating the state of the launch and control equipment during each test phase, launch process, and flight phase, and mimicking various fault conditions during the launch vehicle's test and launch. The control system backend, measurement system backend, and power measurement and control system backend share the same basic logic as the actual control system, measurement system, and power measurement and control system.

[0060] 1. Control system backend

[0061] The back end of the control system consists of the control consoles and simulation computers used by various positions in the command and control hall. The control system software is deployed on the simulation computers, and the control system software includes a main control module, a virtual display module, and a data processing module.

[0062] The main control module is the core of the measurement and control system, enabling automated control and data interpretation. The control backend control console and the main control module execute the control system's measurement and launch process. The simulation computer virtual display module and data processing module receive and interpret data from the control system's front end via the central control network, immediately alerting and pausing the process in case of anomalies. The control system also forwards command commands, feedback orders, and control system data through the data processing module, interacting with the measurement system's backend and the power measurement and control system's backend via the central control network.

[0063] The virtual display module can receive and display front-end power information, rocket data, bus leakage test information, and equipment self-test information via the central control network. Furthermore, the virtual display module is equipped with virtual buttons, allowing the test and launch operations to be completed when the main control panel buttons fail.

[0064] The data processing module is responsible for forwarding process control commands between the main control module and the central control network command and control module, transferring the control system test status information and data from the main control module to the central control network command and control module as required. Simultaneously, it displays the test process information and test data from the main control module. The data processing module can also interpret the received simulation parameters from various tests, such as timing data of the onboard equivalent, inertial navigation system data, battery voltage, servo mechanism curves, and thrust adjustment, and generate interpretation reports.

[0065] 2. Measurement system backend

[0066] The measurement system backend includes a measurement system backend equivalent, a computer, and measurement system command and control modules, real-time monitoring modules, data processing modules, data storage modules, data interpretation modules, and measurement parameter binding modules deployed on the computer. The measurement system backend equivalent mainly receives measurement system data sent by the measurement system frontend equivalent through the central control network, processes the data, and then sends it to the measurement system computer and other systems through the central control network.

[0067] The measurement system command and control module is the core of the measurement system for command and control. It can send control commands through the central control network to the front-end equivalent unit, the back-end equivalent unit, and the on-rocket equivalent unit of the measurement system, and simulate the power-on and power-off control of the above-mentioned equipment.

[0068] The data processing module can process the test data received by the measurement system front-end equivalent unit from the back-end equivalent unit in real time, and store and send the processing results to the main control network and other systems in real time.

[0069] The data storage module stores measurement data in real time.

[0070] The data interpretation module interprets key data such as voltage and current processed by the data processing module in real time and immediately alerts the user if any abnormality occurs.

[0071] The real-time monitoring module monitors the data processed by the data processing module in real time.

[0072] 3. Power Measurement and Control System Backend

[0073] The backend of the power measurement system includes a computer and a power command and control module, a power measurement and control module, and a measurement and control module deployed on the computer.

[0074] The power control module is the core of the power measurement and control system, which simulates the power-on and power-off of the front-end equivalent unit of the power measurement and control system and controls the on-board solenoid valves. It sends the power-on and power-off commands and the on-board solenoid valve control commands to the on-board equivalent unit through the central control network. At the same time, it forwards the control commands to the main control module of the control system and the measurement system control module through the central control network.

[0075] The power measurement and control module collects and monitors various status parameters of the front-end equivalent of the power measurement and control system, the opening and closing status of the solenoid valves simulated by the on-rocket equivalent, and the parameters of the on-rocket power system through the central control network. Abnormal parameters will be immediately alerted.

[0076] The measurement and control module collects and monitors the status parameters of the front-end and back-end equivalents of the measurement system through the central control network, collects and monitors the status parameters of the on-rocket equipment of the measurement system simulated by the on-rocket equivalent, and transmits them to the real-time monitoring module of the measurement system. Abnormal parameters will be immediately alerted.

[0077] 4. Central Control Network System

[0078] The central control network system mainly includes a server and a central control network command and control module deployed on a computer.

[0079] The central control network command and control module, based on the test procedures, connects to the backends of various subsystems, sends test procedure commands to each system, and completes centralized management and information communication functions for the test procedures. This achieves system test procedure and information sharing, realizing integrated testing and control of the launch vehicle's ground network. The central control network command and control module can also display the status of devices currently connected to the central control network, indicating whether the devices are online or offline.

[0080] 5. Logic Control Module

[0081] The logic control module is deployed on the server of the overall control network system. As the central hub of the test and deployment process simulation platform, it controls the logic display and control of all front-end equivalents and participates in the interaction between the front-end equivalents and the back-end of each system. The logic control module consists of an interaction simulation module, a parsing and forwarding module, a device logic control module, and a device management module.

[0082] The interactive simulation module can interact with the measurement system backend, power measurement system backend, central control network command and control module, and control system backend based on the data received by the central control network command and control module, sending the aforementioned status information and data to each backend; it can also interact with the on-board equivalent, sending the status information data required by the on-board equivalent to the on-board equivalent and receiving control data from the on-board equivalent; it can interact with the logic control module, receiving control data from the process control module; and it can interact with each front-end equivalent, distributing control commands to each equivalent for hardware indication and display (e.g., light on / off, instrument values, etc.), and collecting and storing the status data of each equivalent (e.g., switch on / off, connector switching on the equipment, etc.).

[0083] The parsing and forwarding module parses the received data, analyzes the source, destination, and type of information, processes and encapsulates the information according to its type, and sends it to the corresponding system's software module according to the requirements of the source and destination.

[0084] The equipment logic control module is the logic hub of each front-end equivalent unit. It can drive each front-end equivalent unit to send data according to logic in real time based on the current stage of the testing process, the status of the front-end and back-end equipment, and key data from both sides. It judges the correctness of the operational logic of each equivalent unit and software module in the current state. If correct, it controls the corresponding equivalent unit to execute the operation response or sends the correct data to the back-end software module; if incorrect, it feeds back the abnormal status to the corresponding equivalent unit or back-end software module. The information on the current stage of the testing process comes from the process step information of the process control module. After determining that all the logic of a process step is satisfied, the logic control module feeds back the completion status of the current process step to the process control module. The logic control module controls the front-end equivalent units by controlling the equipment status of each equivalent unit through control commands, such as changing the value of the pressure gauge on the equivalent unit, turning the lights on and off, and changing the simulated equivalent unit status display data such as voltage, current, speed, and frequency. For example, during the test, the main control module of the control system sends an "ignition" signal to the on-board equivalent. The equipment logic control module determines whether it has received a "strong blow-off" signal from the power measurement and control system or a "permitted ignition" signal. Only after receiving all of the above signals will it send an "ignition" signal to the on-board equivalent. Otherwise, it sends an error message to the main control module of the control system to remind that the ignition conditions are not met.

[0085] The equipment management module manages the front-end equivalent data and status, and monitors the online status of the equivalent unit equipment in real time. If the equivalent unit equipment goes offline, the corresponding status is fed back to the control and command software of the central control network system.

[0086] 6. Process Control Module

[0087] The process control module is deployed on the server of the central control network system. As the driver module for the test process, it drives the device logic control module and various system main control / command and control modules to perform tests according to the currently selected test item and the preset test process steps. The process control module mainly interacts with the logic control module, sending the test process information, i.e., the current process step, to the logic control module for logic control, and receiving feedback from the logic control module indicating the completion status of the current process step. Once the process control module receives the completion status of the current process step, it sends the next process step to the logic control module to drive the overall test process.

[0088] The process control module also has the ability to pre-set fault modes. When training for troubleshooting a specific fault mode is required, the corresponding fault code can be entered into the process control module, which will then execute the process steps containing the troubleshooting procedures. This fault code is sent to the logic control module before the test begins. The logic control module then uses logic judgment and information transmission containing the fault mode to drive the entire troubleshooting process training. For example, entering the fault code "Power Startup Abnormality" will include a "Power Switching" hardware operation in the process steps.

[0089] III. Measurement and Control Interface Design

[0105] In summary, the test and launch control process simulation training platform proposed in this invention supports training requirements for single-person, multi-person collaboration, and the entire process. It supports subsystem testing, overall inspection testing, and simulated launch, covering test items and operational content for cryogenic liquid propellant launch sites. The personnel in the test and launch positions are consistent with the actual positions, including 01 commander, system commander, back-end operator, and front-end operator.

[0106] The command and control hall is a computer cluster simulating a real command and control hall.
