Problems solved by technology

This method has the following disadvantages: the equipment cannot be used universally, and each launch vehicle model is equipped with a dedicated equivalent device; each development of the measurement, launch and control system equipment requires the development of a new corresponding launch vehicle equivalent device, which costs a lot The human cost and financial cost will affect the equipment development process
The previous dedicated mode for equivalent devices has been unable to meet the high efficiency requirements of ground equipment self-inspection testing
[0005] Chinese patent application publication number CN103869808, published on June 18, 2014, titled "Launch Vehicle Equivalent System Based on Distributed Technology", discloses a launch vehicle equivalent system based on distributed technology. The technical solution adopts distributed PLC technology, which greatly reduces the number of long cables and reduces the input of manpower and material resources, but the disadvantage is that it is not universal and cannot meet the test task requirements of different types of launch vehicles

Embodiment 1

[0046] see figure 1 , a launch vehicle equivalent device system, the equivalent device simulates the electrical interface between the launch vehicle and the rocket ground measurement and launch control system 5, including the equivalent device PLC master station 2 and several distributed combinations 3; the equivalent device PLC and the distributed Combinations 3 are connected by bus, and the distributed combination 3 is networked and controlled; each distributed combination 3 is respectively connected to the electrical interface corresponding to the rocket ground measurement and launch control system 5, and the distributed combinations 3 are connected sequentially through the bus, and the distributed Combination 3 includes general-purpose distributed combination (not marked in the figure) and special-purpose distributed combination (not marked in the figure); the general-purpose distributed combination corresponds to the test requirements of various types of launch vehicles; t...

Embodiment 2

[0052] Such as image 3 As shown, in this embodiment, on the basis of Embodiment 1, the level III control equivalent combination 6 is replaced by the level II control equivalent combination 11, and the push force equivalent combination 12 is added to the non-intelligent expansion combination 4, and the rest are the same as Embodiment 1 is the same or similar and will not be repeated here. Among them, the level II control equivalent combination 11 is a dedicated intelligent distributed combination, the pushing equivalent combination 12 is a special non-intelligent expansion combination, and the pushing equivalent combination 12 is connected to the level II control equivalent combination 11 through a signal transfer cable. connected.

[0053] The push force equivalent combination 12 is a model-specific system in this example. As a non-intelligent expansion combination 4, it can be added or removed according to task requirements, and the complexity of distributed PLC module netw...

Abstract

The invention discloses an equivalent device system of a launch vehicle, wherein the equivalent device simulates the electrical interface of the launch vehicle and a vehicle ground test and control system. The system comprises an equivalent device PLC master station and a plurality of distributed combinations, wherein the distributed combination comprises a universal distributed combination and aspecial distributed combination. The universal distributed combination corresponds to the testing requirements of the launch vehicles of multiple models, and the special type distributed combination corresponds to the special testing requirement of the launch vehicle of a single model. The equivalent device system of a launch vehicle can meet the testing task requirements of the launch vehicles ofdifferent models, so that the cost is reduced.

Description

technical field [0001] The invention belongs to the field of aerospace measurement and control equipment design, in particular to a carrier rocket equivalent system. Background technique [0002] The equivalent device simulates the electrical interface between the launch vehicle and the ground measurement, launch and control system, completes the self-inspection test of the ground measurement, launch and control system, and ensures that the ground measurement, launch and control system works normally before docking with the rocket, including the coordination of software and hardware. ,reliability. [0003] In the past, launch vehicle equivalents were highly specialized test equipment, and different equivalents were developed according to the mission requirements of different types of rockets. This method has the following disadvantages: the equipment cannot be used universally, and each launch vehicle model is equipped with a dedicated equivalent device; each development of...
