Embodiment
Analyze by the signal type that launch vehicle measurement is sent, its signal type generally can be divided into two classes: signal when a class is long, be used for realizing distributing function, as " battery is heated ", " battery activated " etc., need to keep for a long time until test end once this type of signal is connected.Another kind of is momentary signal, is used for realizing controlling function, and as " reset ", " turning electricity " etc., this type of signal mainly provides DC pulse information, does not need to keep for a long time completing corresponding function.Parts simulator needs equivalent flight control system, correctly receives the above signal that launch vehicle measurement sends, and provides clear and definite test result for tester's interpretation.
The utility model is achieved from signal indicating circuit and external interface two aspects.
1) adopt the mode of pilot lamp and current-limiting resistance, distribution signal and control signal that launch vehicle measurement is sent show, using the light on and off of pilot lamp as judge that whether normally launch vehicle measurement signal sends function foundation.According to the type of launch vehicle measurement transmitted signal, instruction and instantaneous instruction two classes when functions of indicator light is set to length.
When long, instruction is mainly used in distribution signal to show, before this type of signal finishes to this test after launch vehicle measurement sends, in continuing on-state.
Instantaneous instruction is for showing the Instantaneous Control signal such as " reset ", " turning electricity ".Because the duration of momentary signal is generally shorter, the light on and off of short time pilot lamp are made troubles to tester's observation, and careless slightly just can causing fails to judge or judge by accident.Therefore, the utility model the similar pilot lamp of signal Presentation Function, is also provided with the pilot lamp with self-retaining function, except being provided with for momentary signal when long after momentary signal is connected in short-term and disconnected, self-sustaining pilot lamp can keep momentary signal, is convenient to tester and observes.
