It should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as broad guidance for those skilled in the art and not as a limitation to the present invention.

[0026] In the following paragraphs, the present invention will be described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present invention will be clearer according to the following description. It should be noted that the drawings are all in very simplified forms and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the objectives of the embodiments of the present invention.

[0027] As Figure 1 shown, an embodiment of the present invention provides a liquid launch vehicle test run measurement and control platform adaptable to multi-task scenarios, including an execution device digital configuration channel, a sensor perception system, a sub-scenario logic automatic control system, an online editing and downloading system for a timing instruction set, a high-precision timing instruction combination execution system, a measurement parameter digital configuration channel, a platform management measurement parameter adaptive display system, a platform management adaptive control system, and a valve and pyrotechnic control system.

[0028] In the above embodiments, the sensor sensing system is used to collect relevant parameter information during the operation of the execution device, and the valve and pyrotechnic control system is used to execute the control actions during the test run. They are all basic measurement and control function facilities of the test stand.

[0029] Specifically, the relevant parameter information collected by the sensor sensing system includes at least one of temperature, pressure, and vibration. It mainly selects sensors for the extreme environment during the engine test run. The sensors available for selection mainly include pressure sensors and pulsating pressure sensors suitable for low-temperature liquid pipeline environments, vibration sensors for low-temperature metal planes, and temperature sensors for high-temperature environments. The distributed sensor network aggregates information in a wired or wireless manner according to a secure communication protocol for the backend display software or the main control software to implement closed-loop control strategies or test command decisions.

[0030] The valve and pyrotechnic control system includes the on-off control and opening adjustment of the low-temperature liquid pipeline, the on-off control and throttling control of the high-pressure gas pipeline, and the ignition, shutdown, automatic shutdown, and emergency shutdown control of the engine.

[0031] Furthermore, the parallel and series relays used in the valve and pyrotechnic control system reduce the probability of false alarms and missed alarms, and a current acquisition circuit is set up to evaluate the working state of the execution device.

[0032] In the above embodiments, the digital configuration channel for measurement parameters is used for the digital configuration of measurement parameters. The sensor configuration file uniquely represents the specific requirements for parameter measurement in a single test run, that is, it is used to define the configured measurement parameters and measurement channels according to the user's usage situation; the digital configuration channel for the execution device is used for the digital configuration of the control channel. The control channel configuration file uniquely represents the specific requirements for control parameters in a single test run, that is, it defines the configured control parameters and control channels according to the actual situation of the user. These configuration processes are the specific modeling and digital processes of the user's distributed measurement and control requirements. Based on these configuration files, the measurement and control requirements for the user's specific test run can be supported and completed.

[0033] Specifically, the custom configuration range of the digital configuration channel for measurement parameters includes: configuring the name, KB value, channel, threshold, etc. of the sensor. The custom configuration range of the digital configuration channel for the execution device includes configuring the name and channel of the execution device.

[0034] In the above embodiments, the sub-scenario logic automatic control system synthesizes the information collected by the sensor perception system and performs closed-loop control on the execution device according to the preset logic; the high-precision timing instruction combination execution system receives the timing instruction combination edited and downloaded by the timing instruction set online editing and downloading system, and controls the execution device to operate in accordance with the precise clock sequence. The specific control logic is as follows: receiving the ignition instruction from the backend as the time baseline of the timing instruction, and outputting the timing instruction signal with a precise time length according to the precise time interval requirement. These two functions are high-order requirements in the measurement and control of the engine hot test run, which can ensure the accuracy, instantaneity, and stability of the control process.

[0035] Specifically, the sub-scenario logic automatic control system supports user-defined sub-scenario control logics, including the control logic settings for normal / auto / emergency shutdown scenarios, the control logic settings for gas supply along the way points, and the control logic settings for liquid supply along the way points. The implementation of the closed-loop control strategy can achieve instant response of specific scenarios according to the preset logic, ensuring the stability and reliability of the intervention. The high-precision timing instruction combination execution system can automatically and accurately implement the test run control according to the user settings. The accurate relative time instruction set is the key link in the control of the carrier rocket engine hot test run, which plays a crucial role in performance analysis and technical improvement.

[0036] In the above embodiments, the platform management measurement parameter adaptive display system is used to display and update the measurement parameter information of the sensor perception system according to the configuration information of the measurement parameter digital configuration channel. The displayed parameter information mainly includes parameter name, threshold range, value, change curve, and parameter envelope; the platform management adaptive control system automatically updates the control interface according to the configuration information of the execution device digital configuration channel, provides control operation interaction and control result display to the user, that is, automatically realizes the update of control parameters, feedback, etc., provides control interaction operation buttons to the user, and displays the control result; the platform management timing instruction set online editing and downloading system is used for the user to edit and download the timing instruction combination online through the backend main control software, and binds the adapted timing instruction logic group for each specific test run process for the user. The implementation of these three functions is based on the configuration file, relying on the powerful logic processing ability of the platform to model the specific test run process and instantly form the measurement and control ability.

[0037] Specifically, the above-mentioned configuration file is completed according to the distribution status of the sensors and execution devices before the test run starts.

[0038] It should be noted that after the file configuration is completed, file verification before the test run is also required. The specific operations are as follows: First, run the software, test the frame format channel and the control channel, and observe whether the display interface and the control interface are consistent with the basic configuration information; then, perform simulated input on the sub-scenario preset logic automatic control system and observe whether the control output is consistent with the expectation; finally, use an oscilloscope to observe whether the output of the timing instruction set edited and downloaded online is consistent with the set result in terms of order and time interval. After the above verification work, the test run can be executed.

[0039] In summary, the test run measurement and control platform for liquid launch vehicles adaptable to multi-task scenarios provided by the present invention has at least the following advantages compared with the prior art:

[0040] By configuring the basic sensor perception system and the valve and pyrotechnic control system, a measurement and control unit with comprehensive functions is established; through the powerful logic processing function of the platform combined with the configuration file, it can intelligently form the measurement and control capabilities and the interactive operation display interface according to the actual distributed measurement and control requirements of users; the platform can meet the high-level requirements of customers, including but not limited to: being able to implement a closed-loop control strategy according to the preset scenario, being able to edit and download the timing control instruction set online, and being able to accurately control the implementation of the timing instruction set according to the unified time standard; through the realization of the above functions, customers only need to complete the configuration file according to the actual scenario, and can use the processing power of the measurement and control platform to complete complex and strict measurement and control implementation strategies.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
