Description

The utility model relates to information-measuring systems and is intended to test the electrical and informational interaction of a rocket with a carrier equipment using a device that simulates the pre-flight function of a rocket.

A simulation device containing an inert rocket, a microprocessor, a memory unit, a data acquisition and processing module is known. This device imitates the pre-launch functions of the rocket in response to the data received from the aircraft (US Patent No. 5591031) and is intended to train the pilot and train loading and unloading teams. The disadvantage of this device is the impossibility of implementing with its help a reliable simulation due to the lack of verification of the reaction of the aircraft weapons control system to digital exchange errors and errors of one-time commands. This device also does not have an information display module.

A device is known for simulating the functioning of a control object during monitoring and debugging of control computing systems (RU, AS No. 1254492), which provides two-way exchange of information with a control object using, for example, an intersystem interface according to GOST 18977-79. This device comprises a matching unit, a comparison unit, a unit for setting a feature part of a monitored parameter, a unit for setting the type of simulated device malfunction, an indication unit for visualizing the monitored parameters (may include LEDs). Disadvantages of this

The device allows for the monitoring and debugging mode of a digital control system that runs on regular programs in real time. The disadvantages of this device is the inability to implement with it a completely reliable simulation associated with the lack of exchange of one-time commands, because at

this device does not have an input-output module for one-time commands and a module for setting errors of one-time commands.

Using this device, preflight testing of the launch equipment of the aircraft is carried out.

The disadvantages of this device are the inability to implement with its help a completely reliable simulation of the interaction of the rocket with the equipment of the carrier due to the lack of verification of the reaction of the launch equipment of the aircraft to digital errors and errors of one-time commands existing in real conditions.
