Background
The safety problem of the hypersonic high-temperature wind tunnel is outstanding, the wind tunnel test relates to various dangerous media such as inflammable, explosive, strong oxidation, deep cooling and the like, equipment is in high-pressure, strong vibration, high-temperature and cold-heat exchange environment, and the dangerous factors are numerous. The time and economic cost of wind tunnel testing is high: before a wind tunnel test, the time consumption of the inspection and preparation processes of hundreds of devices of nearly 10 systems of a hypersonic high-temperature wind tunnel is averagely 4-8 hours; the caliber of the hypersonic high-temperature wind tunnel reaches 3 meters, the flow rate is hundreds of kilograms per second, and the consumption cost of one-time dynamic combustion reaches more than ten-thousand yuan. The wind tunnel test flow is complex, and related field devices of a plurality of systems such as fuel, liquid oxygen, liquid nitrogen, high-pressure air, nitrogen, vacuum, cooling water, model feeding, measurement and the like are required to be accurately cooperated by a wind tunnel control program, so that the wind tunnel control program can act and respond according to time sequence and interlocking conditions strictly, and the safety of each system of the hypersonic-speed high-temperature wind tunnel and the effective test result are ensured.
During the wind tunnel test process, corresponding adjustment and optimization are always carried out according to different test state parameters and actual working conditions of equipment. Because the wind tunnel system equipment has a strong coupling relation of time sequence and interlocking, any change in the wind tunnel test flow can affect a plurality of related steps, and the wind tunnel control program has to carry out corresponding design change one by one, so that the workload is huge.
Adjustment of wind tunnel test procedures and changes to wind tunnel control programs introduce multiple risk factors: firstly, because the test responsible person considers the changes, changes of some relevant links are omitted in the wind tunnel test flow; secondly, a software engineer cannot accurately understand the wind tunnel test flow, and the time sequence and logic cannot completely meet the test requirements; and thirdly, the control program code has bug errors and cannot be smoothly executed according to the expected design requirements. These risks are particularly acute during the device and test commissioning phases. For a hypersonic high-temperature wind tunnel, if the risk factors exist, once the actual operation is started, the payment cost is very high: if the data is not valid, manpower and material resources are wasted; accidents such as damage, explosion, combustion and the like of wind tunnel equipment occur.
Meanwhile, as the field equipment of the hypersonic high-temperature wind tunnel is frequently operated under a high-load condition, abrasion or aging inevitably occurs, so that the dynamic characteristics of the field equipment can be changed to different degrees, the time sequence requirement of the previous test flow cannot be met, even faults occur, and the safety of the wind tunnel equipment and personnel is seriously influenced.
In order to eliminate the risk factors to the maximum extent, the wind tunnel operating regulations require that necessary correctness and feasibility tests be carried out after each flow adjustment and control program change; moreover, after the performance of a certain device is detected to be changed obviously or maintenance is carried out due to a fault, the device is required to perform actual action in the verification process of the wind tunnel test flow, and the device is confirmed to be in a good state and can participate in the test.

Example 1
The embodiment is an application example of a hypersonic high-temperature wind tunnel. The specific situation is as follows: the newly modified test flow requires that the air throttle valve is opened when T is 0 seconds; opening the air main valve when T is 1 second; and when the T is 3 seconds, carrying out valve position interpretation, if the main valve is completely opened and the opening of the regulating valve is more than 60%, switching to a liquid oxygen filling process, and otherwise, switching to an emergency stop operation process. Meanwhile, since the main valve is maintained due to wear, it is necessary to actually check the operation state of the main valve. The main valve is set to be 'real operation', other equipment is set to be 'simulation', no medium flows in the wind tunnel when the test process is executed, the system is safe, and the actual condition of the main valve is also confirmed while the test process is verified. According to the data given by the valve manufacturer, the full-open time of the throttle valve is 4 seconds, the valve position is linearly increased along with the time, and the estimated open time is 1.9 seconds after the main valve is maintained. The wind tunnel control program is in the actual operation state, the main valve is in the closed state, and the throttle valve entity opening degree is 0%. The simulation process of the test flow comprises the following steps:
a. the operator sets the main valve as 'real operation' on the upper computer interface, and all the other devices are selected as 'simulation' mode;
b. the operator set the throttle full open time to 4 seconds;
c. setting a wind tunnel control program to execute mixed simulation by an operator;
except the main valve, the control modules of the throttle valve and other field devices receive a simulation instruction, and output signals of the actual input and output interfaces are latched firstly; then, the connection between the program control intermediate interface and the actual input/output interface is disconnected, and then the connection between the program control intermediate interface and the simulation submodule is connected, namely the connection is shown by a dotted line in fig. 1;
when T is equal to 0, the wind tunnel control program sets an opening command signal of an intermediate interface of the throttle valve control module to be 1, the throttle valve simulation submodule detects the opening command and determines to open the valve, and according to a set value, the opening indication signal of the throttle valve is linearly increased by 100% from 0% in the following 4 seconds;
when T is 1, the wind tunnel control program sets the opening command signal of the intermediate interface of the main valve control module to 1, and since the main valve does not receive the "emulation" command, the main valve program controls the intermediate interface to remain connected with the actual input/output interface, as shown by the solid line in fig. 1, the opening signal of the actual output interface is set to 1 at this time, the main valve is driven to perform the opening action, and the main valve is actually opened after 1.95 seconds;
when T is 3, the wind tunnel control program carries out valve position interpretation, the simulation opening degree of the throttle valve is 75%, the main valve is opened in place, the interlocking condition is met, and the process is switched to a liquid oxygen filling process;
d. the wind tunnel control program continues to execute subsequent processes, and an operator observes simulation conditions of other field devices and execution results of the test processes on an upper computer interface in real time until all the processes are simulated and executed for 10 seconds;
e. the method comprises the steps that an operator switches a wind tunnel control system back to an actual operation mode, except for a main valve, other field device control modules write back corresponding variables of a program control intermediate interface by using output signals of a device actual input and output interface latched before simulation, wherein a valve opening command signal of a throttle valve intermediate interface is set to be 0, a valve closing command signal is set to be 1, connection of the program control intermediate interface and the actual input and output interface is restored, the opening degree indication of the throttle valve intermediate interface is 0%, and interface signals are consistent with the states of field devices and are the states before simulation; the main valve still maintains the opened state in the process of flow verification, the main valve program controls the opening command and the opening position of the intermediate interface to be 1, the actual output interface opening signal and the opening position feedback are 1, and the actual output interface opening signal and the opening position feedback are consistent with the actual state of the main valve;
f. the wind tunnel control program is set to be in a real operation mode on an upper computer interface by an operator, enters a real operation state, and operates field equipment such as a main valve, a throttle valve and the like to complete corresponding actions.
In the embodiment, the hybrid simulation is selected on the upper computer interface, the simulation and the actual operation hybrid execution of the wind tunnel equipment are realized during the verification of the test flow, the test flow runs for 10 seconds, the detection on the correctness and the feasibility of the flow is finished, the actual action condition of the main valve after maintenance is basically in accordance with the expectation, and the test requirement can be met.
