Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present invention and the descriptions thereof are for illustrating the present invention only and are not to be construed as limiting the present invention.
Example 1
As shown in fig. 1-2, the automatic switching device for system architecture and wiring relation of the present invention includes a signal generating device, a router, a connection switching box and a mating cable, wherein the signal generating device sends command information to any one or more connection switching boxes through the router, the connection switching box includes a network interface, a level processing unit, and an interface circuit, the router is connected with all network interfaces, the level processing unit analyzes the level signal after the command information is sent to the interface circuit, and the interface circuit is connected with a device to be tested and a device to be tested simulator through the mating cable.

Taking the tuning control function of a communication navigation monitoring system (CNS system) as an example:
architecture 1: TCP is directly connected with a radio station;
architecture 2: TCP connects to RDIU, RDIU connects to radio station;
architecture 3: the display control system is connected with the RDIU, and the RDIU is connected with the radio station.
If automatic switching is not possible, when different system architectures are verified, a large number of connection relations need to be changed according to the currently verified architecture, which is time-consuming and labor-consuming.
According to the connection mode of the device, when the architecture 1 is needed, the signal generating device controls the connection switching box 2 to select the connection of one end of the TCP, so that the TCP is interconnected with the radio station equipment; when the architecture 2 is needed to be realized, the signal generating device controls the connection switching box 1, selects the connection of one end of the TCP, realizes the interconnection of the TCP and the RDIU, controls the connection switching box 2, selects the connection of one end of the RDIU, and realizes the interconnection of the RDIU and the radio station equipment; when the framework 3 is needed to be realized, the connection switching box 1 is controlled through the signal generating device, one end of the display control system is selected to be connected, the interconnection of the display control system and the RDIU is realized, the connection switching box 2 is controlled, one end of the RDIU is selected to be connected, and the interconnection of the RDIU and the radio station equipment is realized.
Example 2 differs from example 1 in that:
the device comprises two connection switching boxes, wherein the connection switching box 1 is connected with a device A and a device simulator A; the connection switching box 2 connects the device B and the device emulator B. The driving circuit is controlled by the control signal of the command analysis module, and the interface circuit is controlled by the switching circuit, so that the following four connection relations can be realized: device A-device B, device simulator A-device B, device A-device simulator B, device simulator A-device simulator B. In the practical application process, as shown in fig. 2, not only all channels of the whole device are switched, but also a certain channel may be switched, for example: device C may be controlled by commands to connect to device a, but some of the channels (e.g., channel 80) may use the corresponding channel in device B.
Example 3 differs from example 1 in that:
also exemplified is a communication navigation monitoring CNS system:
the radio station apparatus includes: VHF station, HF station, DME station, ADF station, ILS station, VOR station, the same corresponding simulators comprising: VHF simulator, HF simulator, DME simulator, ADF simulator, ILS simulator, VOR simulator.
In the conventional method, the cable connector of the VHF radio and the cable connector of the VHF emulator are made into the same specification, and when the cable connector needs to be switched, the current cable needs to be disconnected first and then the cable needing to be switched needs to be connected, which is time-consuming and labor-consuming. According to the connection mode of the device, when the VHF radio station is required to be connected to the avionic system, the signal generating device controls the connecting line switching box 1 to select one end of the VHF radio station, so that the VHF radio station is connected with the avionic system. Similarly, when the VHF simulator is required to be connected to the avionic system, the signal generating device controls the connecting line switching box 1, and one end of the VHF simulator is selected to realize connection of the VHF simulator and the avionic system.
Compared with the traditional method, the three embodiments are practical, the design of the device and the experimenters can quickly realize the automatic switching of the system architecture and the wiring relation according to the current requirements, and the resource waste caused by the traditional changing mode is effectively avoided.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the invention, and is not meant to limit the scope of the invention, but to limit the invention to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the invention are intended to be included within the scope of the invention.
