(Prior art) Conventionally, when installing multiple different types of radio equipment such as IIF, VIIF, and UHF, as well as their data terminal equipment, navigation equipment, etc., in a limited space of a moving object such as an aircraft, ship, automobile, or other vehicle, Is it possible to remotely control each radio device and navigation device by operating the controller of each device installed in a location where the pilot or pilot can operate it? 11 I was doing it.

For example, aircraft have a unique physical shape, and the controls for each device are installed in the pilot's cockpit seat.
The main body was installed in the equipment room at the rear of the aircraft and was controlled remotely using each controller.

FIG. 1 is a block diagram showing an example of the configuration of equipment systems of various conventional radio devices. In the figure, 1 to 4 are each IIP
, VIIP, UIIP, and a plurality of different types of radio equipment in the SHF band, each of which is equipped with controllers 11 to 14, and a pilot or operator controls and monitors the various radio equipment using each controller.

Data terminal devices 5 to 8 and controllers 15 to 18, which are used in addition to each radio, operate in the same way as the radio, and these are operated by the 19 operation controller IC5 (Inter
microphone 20° speaker 21. It is connected to the headset 22 and forms a communication system with other mobile stations and fixed stations.

In this way, in the past, control equipment corresponding to each new or expanded wireless communication device was installed in a limited location on a moving body and operated remotely, but the physical space in which the equipment is installed is There are many restrictions on the equipment and the installation locations can vary, resulting in a large number of cotton wires.Furthermore, each device has its own operation items and procedures, making it easy for errors to occur.

Furthermore, even if an attempt was made to install other equipment in order to improve the system at a later date, there was not enough space for the equipment, which was inconvenient in terms of system expandability. Furthermore, when changing the conditions after the power is turned on to start system operation or during operation, it takes time to set various conditions by operating switches corresponding to each device each time, resulting in a lack of speed. Also, due to the equipment configuration, it was not possible to perform a self-diagnosis of the entire system.

(Objective of the Invention) The object of the present invention is to solve the problems described above when installing and operating a plurality of different types of communication devices in a mobile body such as an aircraft or a car that has little equipment space, and to An object of the present invention is to provide a radio device integration device that can integrate a plurality of different types of radio devices installed on the device and perform initial settings and operation control operations.

(Structure and operation of the invention) The radio device integration device of the present invention connects a plurality of disparate radio devices installed in a moving body with little equipment space and data terminals respectively corresponding to the disparate plurality of radio devices. A first interface unit including an interface circuit necessary for remotely controlling and monitoring a plurality of different types of wireless devices; the first interface unit; and a microphone.

It is connected to a control bus line that passes digital control signals between the second interface, which is provided with an interface circuit for speakers, etc., and other systems, and is connected to a control bus line that passes digital control signals. a plurality of wireless integrated controllers, which can be connected to an audio bus line for passing analog audio signals, provided between the first interface unit and the second interface unit, and the plurality of wireless integrated controllers A device characterized by having a plurality of operation controllers connected in parallel to each of the controllers for extracting frequently operated items in parallel from among the operation items of the wireless integrated controller and performing control operations. It is.

The present invention will be explained in detail below with reference to the drawings.

For example, in an aircraft, one unit is for the pilot and the other unit is for the co-pilot.

Furthermore, considering the resilience of the entire system, even if the 25.26 system should fail during operation, the 27.28 system can be used in place of it in a working/standby relationship. That is, it is natural to think in this way when all devices of one moving body are collectively controlled and monitored like this system.

Operation control system (ICS) The operation control system of 29 and 31 is

This shows data communication (DATA2) for ECCM such as 1). Out of these four items, the underlined DATAI mode in item 3 indicates that it is currently set, and this is indicated by 5ECUR in item 2.
When you want to change to E VOICE, turn on switch 72 to set 5ECIIRE VOICE in item 2 and display an underline, and at the same time change to DA in item 3.
The underline of TA 1 disappears.

In this way, if the setting conditions to be selected for the VIIF radio are selected from the display items in Figures 6 and 7, the NE
By turning on the XT switch 75, the screen returns to the first selection menu screen (FIG. 4). Thereafter, the same setting operation is repeated for devices in other frequency bands.

If you want to perform a system test for each frequency band, select the device for the desired frequency band on the screen shown in Figure 5, and then turn on the (TEST) switch in the switch section shown in Figure 8. The test result is displayed next to the selected frequency band in FIG. 5 as either OK or NG. If NG is displayed, turn on the (TEST) switch again to display detailed data on which part is specifically NG. In this way, each device also has a self-diagnosis function.

Furthermore, since multiple devices of different types can be controlled with a single controller, there is more physical space available, and future system expandability can be expected.

Therefore, it is particularly effective when aircraft, ships, automobiles, etc. are equipped with a plurality of different types of radio equipment and perform complicated operations.
