Embodiment 1

[0020] Such as Figure 1-3 As shown, a device for automatically switching system architecture and wiring relationships in the present invention includes a signal generating device, a router, a connection switching box and supporting cables, and the signal generating device sends command information to any one or more connections through the router. A line switch box, the line switch box includes a network interface, a level processing unit, and an interface circuit, the router is connected to all network interfaces, and the level processing unit analyzes the command information and sends the processed level signal to the interface circuit, The interface circuit connects the device under test and the device emulator under test through a matched supporting cable. The level processing unit includes a data collection module, the data collection module collects the command information forwarded by the router, and sends it to the command parsing module for analysis, and the command ...

Embodiment 2

[0027] Embodiment 2 differs from Embodiment 1 in that:

[0028] It includes two connection switching boxes, the connection switching box 1 connects the device A and the device emulator A; the connection switching box 2 connects the device B and the device emulator B. The drive circuit is controlled by the control signal of the command analysis module, and the following four connection relationships can be realized by switching the circuit to control the interface circuit: device A—device B, device emulator A—device B, device A—device emulator B , Device emulator A - device emulator B. In practical applications, such as figure 2 As shown, it is not only the switching of all channels of the entire device, but also switching of a certain channel. For example, the connection between device C and device A can be controlled by command, but one of the channels (such as: channel80), using the device Corresponding channel in B.

Embodiment 3

[0029] Embodiment 3 differs from Embodiment 1 in that:

[0030] Also take the communication navigation monitoring CNS system as an example:

[0031] Radio equipment includes: VHF radio, HF radio, DME radio, ADF radio, ILS radio, VOR radio, and the corresponding emulators include: VHF emulator, HF emulator, DME emulator, ADF emulator, ILS emulator, VOR Emulator.

[0032] In the traditional way, the cable connectors of the VHF radio station and the cable connectors of the VHF emulator are made to the exact same specifications. When switching is required, it is generally necessary to disconnect the current cable first, and then connect the Cables are time-consuming and labor-intensive.

[0033] From the connection method of this device, it can be concluded that when the VHF radio station needs to be connected to the avionics system, the connection switching box 1 is controlled by the signal generating device, and one end of the VHF radio station is selected to realize the conne...

Abstract

The invention discloses an automatic system structure and wiring relation switching device. The automatic system structure and wiring relation switching device comprises a signal generation device, arouter, wiring switching boxes and auxiliary cables; and the signal generation device is connected with the multiple wiring switching boxes through the router, each wiring switching box comprises an interface circuit, a switching circuit, a driving circuit, a command parsing module, a data collection module and a network interface, the router is connected with the network interfaces of all the wiring switchers, and the interface circuits of the wiring switching boxes are connected with to-be-tested equipment and to-be-tested equipment emulators through the matched auxiliary cables. The signalgeneration device sends command information to the router, and the router forwards the commands to the corresponding wiring switching boxes. The wiring switching boxes are switched on through the network interfaces, the data collection module collects the command sent by the routers and sends the commands to the command parsing module for parsing, and the command parsing module receives the commands and converts the commands into control signals for connected channels.

Description

technical field [0001] The invention relates to an automatic switching device, in particular to an automatic switching device for system architecture and wiring relationship. Background technique [0002] In the design stage of avionics systems, multiple avionics system architectures are often chosen to be analyzed, and integration tests are conducted in the laboratory to verify the pros and cons of different system architectures, and to find an avionics system that meets customer requirements and business models architecture for further development. When verifying the function of the same architecture, it is often necessary to switch between the device emulator and the real airborne device, and access the system to verify the function and locate the fault location. [0003] The problems in the existing technology are as follows: when verifying different architecture solutions, it is necessary to manually change the connection relationship in the system, which is time-consu...
