Detailed Description
The invention will be further described with reference to specific embodiments, and advantages and features of the invention will become apparent from the description. These examples are merely exemplary and do not limit the scope of the invention in any way. It will be understood by those skilled in the art that various changes and substitutions of details and forms of the technical solution of the present invention may be made without departing from the spirit and scope of the present invention, but these changes and substitutions fall within the scope of the present invention.
The specific embodiment discloses a construction method of a valve state detection system in a high-altitude simulation test, which is shown in fig. 1, and comprises the following steps:
step 1, designing a plurality of working condition detection modules and a plurality of first display modules according to the working conditions of the high-altitude simulation test;
step 2, analyzing the compatibility and feasibility of the working condition detection module and the first display module, and screening a first combination module for detecting the working condition of the high-altitude simulation test;
step 3, designing a plurality of valve position state detection modules and a plurality of second display modules according to the valve position states of the valves under the test working conditions;
step 4, analyzing the compatibility and feasibility of the valve position state detection module and the second display module, and screening a second combination module for detecting the valve position state of each valve;
step 5, constructing a subsystem for detecting the test working condition and valve position states of all the valves based on the first combination module and the plurality of second combination modules;
and 6, repeating the steps 1 to 5, and constructing a submodule of each test working condition in the high-altitude simulation test to finish the construction of the valve state detection system.
By constructing a valve state detection system in the air simulation test, professional related operators simulating the high-altitude simulation environment check the different high-altitude simulation test working conditions and the full-closing state, the full-opening state and the regulating state between the full-closing state and the full-opening state related to each valve when the high-altitude simulation test is carried out, and adjust the valve positions of the valves which do not meet the test requirements until all the related valve states meet the test requirements. The function should have the characteristics of simplicity and easy operation, and is suitable for adopting a one-key or automatic operation mode.
In the specific embodiment, taking the air intake direct-exhaust air simulation working condition of the high-altitude cabin in the valve state detection system in the high-altitude simulation test as an example, the construction method of the air intake direct-exhaust air simulation working condition of the high-altitude cabin and the subsystem for detecting the valve position states of all the valves is described:
referring to fig. 2, in the simulation test of the atmospheric air intake in the high-altitude cabin, 7 valves are involved, wherein the valve states are a 2# valve, a 3# valve, a 6# valve and a 7# valve; the valve state is required to be fully open: a 1# valve, a 5# valve; the valve state is that a certain opening degree is required to be maintained: and the 4# valve is used for judging that the equipment state check is passed when the conditions are met, judging that the equipment state check is not passed when the conditions are not met, and giving a corresponding prompt.
First, the valve state detection system can select the upper computer interface development software CIMPLICITY, which has various configuration functions to edit the objects to be displayed, and the visual editing interface is simple and easy to understand and has extremely strong interactivity.
Secondly, designing a plurality of working condition detection modules and a plurality of first display modules according to the working conditions of the high-altitude simulation test; and designing a plurality of valve position state detection modules and a plurality of second display modules according to the valve position states of the valves under the test working conditions.
The module development of the valve state detection system is as follows: the working condition detection module and the valve position state detection module can adopt a manual triggering mode or an automatic triggering mode, and can also be understood as a one-key or automatic operation mode. The display modes of the first display module and the second display module can be text or graphic symbol modes, and the following three combinations can be initially selected according to the modes:
the first is a combination of one-key operation mode and text prompting mode: the method comprises the steps of using a Text Button object as a trigger tool of a one-key operation mode, compiling functional logic into Script sentences and executing the Script sentences by using a Script mode under the Events function, displaying a logic execution result in a character prompting mode, and displaying valve position states through an additional interface;
the second type is a combination of a one-key operation mode and a graphic symbol prompting mode: the method comprises the steps of compiling functional logic into Script statements and executing the Script statements by using a Text Button object as a trigger tool of a one-key operation mode and using a Script mode under the Events function of the Text Button object, displaying a logic execution result through a graphic state conforming to the conventional cognition, and displaying a valve position state through an additional interface;
the third mode is a combination of an automatic operation mode and a graphic symbol prompting mode: an Expression logic Expression executor under a Color Animation function built in a Graph object is used as a trigger tool of an automatic operation mode, the function logic is compiled into a logic discriminant and executed, and finally, a logic execution result is displayed through a Graph state conforming to conventional cognition and aided with necessary text prompt, and meanwhile, a valve position state is displayed through an additional interface.
Secondly, in order to check the check result conveniently, check the valve position state and adjust under the condition that the valve state check is not passed, the valve state detection system should have a succinct prompt interface, and the specific valve position state should be classified according to the test type and be displayed on another interface separately, therefore, compatibility and feasibility analysis need to be carried out on the combination of the detection modes and the display modes, and the best combination of the detection module and the display module is screened out. Namely, analyzing the compatibility and feasibility of the working condition detection module and the first display module, and screening a first combination module for detecting the working condition of the high-altitude simulation test; and analyzing the compatibility and feasibility of the valve position state detection module and the second display module, and screening a second combination module for detecting the valve position state of each valve.
Specifically, the three combinations are all feasible through analysis, the operation mode of the first combination is simpler, but the result prompt information is words, the whole readability is poor, and the text occupies larger space under the condition of limited interface space, so that the integration of functions is not facilitated; the second combination operates in the same way as the first combination, but the result prompt is changed to display the graphic state, so that the readability is high, and the disadvantage is that when an operator forgets to manually click to check, the result prompt may be in an error state; the result prompting mode of the third combination is the same as that of the second combination, but the operation mode is automatic, namely, the operation mode does not need active triggering of operators, is friendly to the operators and has strong compatibility, but the overall development workload of the combination is larger than that of the first combination.
And finally, selecting a manual trigger mode and a graphic display mode as display of the detection result of the working condition of the high-altitude simulation test and selecting an automatic trigger mode and a text display mode as display of the detection result of each valve state in a valve position state monitoring interface through compatibility and feasibility analysis. Designing a first combination module according to the display mode to be a manual triggering sub-module and a graphic display sub-module; the second combination module is an automatic triggering submodule and a text display submodule, and the construction of a subsystem for detecting the valve position state of each valve of the direct-exhaust atmospheric simulation working condition of the atmospheric air inlet of the high-altitude cabin is completed.
The method for constructing the valve state detection system in the high-altitude simulation test disclosed by the invention adopts an automatic mode to assist or completely replace manual operation, has higher stability than manual inspection, can effectively avoid the potential safety hazard problem caused by detection errors and missed inspection caused by human factors in the test process, and can shorten the time consumption of equipment inspection by using the method designed by the invention from 2-3 minutes to 10 seconds in the past, thereby greatly improving the test efficiency, saving the labor cost, having higher popularization value, and being capable of being popularized and applied on other high-altitude simulation test platforms, and promoting the development of an environment simulation system towards the automatic, intelligent and intelligent directions.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
