Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio wave receiving system for receiving and processing radio waves, and more particularly to a system in which the number of receivers that can be handled by one console can be freely set.

[0002]

2. Description of the Related Art In a conventional radio wave receiving system, as shown in FIG. 5, a receiver is controlled by a console.
In FIG. 5, reference numerals 71 to 7N are receivers, and dedicated consoles 81 to 8N are connected to the receivers 71 to 7N, respectively. These receivers 71 to 7N
Converts a received signal into an intermediate frequency by a frequency converter (not shown), and then converts the received signal to a BPF (band-pass filter) not shown.
To extract a necessary frequency spectrum component, and demodulate the modulation component by a demodulation processing circuit (not shown). The frequency spectrum component data and the demodulated data are supplied to the corresponding consoles 81 to 8N. The consoles 81 to 8N execute a receiving process based on the input data. Note that the receivers 71 to 7N receive different targets.

However, in this type of system, the receiver 7
Since the consoles 1 to 7N and the consoles 81 to 8N are connected one-to-one, the number of signals that can be received and processed by the consoles 81 to 8N is limited.

On the other hand, as another example of this type of radio wave receiving system, there is a system as shown in FIG. This figure 6
Is provided with dedicated consoles (1) 101 to 10N having dedicated functions for a certain purpose and dedicated consoles (2) 121 to 12M having dedicated functions for another purpose. These dedicated consoles (1) 101-10N
The receivers 91 to 9N and the receivers 111 to 11M are also connected to the dedicated consoles (2) 121 to 12M on a one-to-one basis. Dedicated console (2) 121-12M
Perform processing of signals received by the receivers 111 to 11M, respectively.
10 to 10N process the signals received by the receivers 91 to 9N, respectively.

However, this type of system has dedicated hardware for each purpose and has a predetermined function. Furthermore, exclusive console (1) 101-1
Since the processing method and functions of the 0N and the dedicated consoles (2) 121 to 12M are significantly different from each other, it is impossible to substitute a normal console when one of the consoles fails. And for this,
It becomes difficult to flexibly deal with various operation situations.

As another example of the radio wave receiving system, as shown in FIG. 7, a wide band receiver 131 for receiving a wide band signal and a narrow band receiver 14 for receiving a narrow band signal are used.
1,142. Among them, the broadband receiver 131 and the narrowband receiver 141 are connected to the console 151,
Narrowband receiver 142 is connected to console 152.

[0007] In this type of system, the number of receivers is determined according to the operational purpose at the time of system development. For this reason, when a situation other than the operation purpose considered at the time of system development occurs, the wideband receiver 131 and the narrowband receiver 141 cannot be used according to the situation other than the purpose, respectively. It will not work efficiently.

[0008]

As described above, in the conventional radio wave receiving system, the console has a dedicated receiver and one
Because of the one-to-one connection, there is a problem that the number of signals that can be received by one console is limited. Further, since the console is divided into dedicated consoles having dedicated functions for each purpose depending on the hardware, the functions that can be received as a system are determined in advance, which makes the system unsuitable for dealing with various operation situations. Furthermore, there are a wideband receiver that receives a wideband signal and a narrowband receiver that receives a narrowband signal, and the number of each receiver is set according to the operational purpose at the time of system development, so it was taken into consideration during system development. If a situation other than operational purposes occurs, the system will not work efficiently.

By assigning functions to the processing devices, one signal processing device can easily handle the entire system without the need for a dedicated signal processing device. Can also contribute. Therefore, a flexible, low-cost, and highly reliable radio wave receiving system that is not restricted by the hardware configuration can be constructed.

[0015] In the above configuration, the plurality of receiving apparatuses are each responsible for a unit receiving band obtained by dividing the entire receivable band into a plurality, and the signal processing apparatus is connected to the desired band of the plurality of receiving apparatuses by the connecting means. And receiving processing of an arbitrary band by connecting to one or more receiving devices in charge and selectively combining the received signals.

According to this configuration, wideband reception is realized by synthesizing reception signals from a plurality of receivers each of which divides the entire receivable band into a plurality of unit reception bands,
When wideband reception is not required, a plurality of receivers are divided and used, so that it is not necessary to separately install a dedicated narrowband receiver and wideband receiver as a whole system, and one signal processing is performed. The device can realize narrowband reception and wideband reception according to the operation purpose and operation status,
Arbitrary received signals can be obtained from these bands. Therefore, it is possible to realize a flexible, low-cost and highly reliable radio wave receiving system which is not restricted by the hardware configuration.

Further, in the above configuration, the signal processing apparatus is characterized in that the signal processing apparatus selectively performs reception processing on the combined output of the received signals of the plurality of receiving apparatuses and the received output of the single receiving apparatus.

According to this configuration, the wideband receiving capability and the narrowband receiving capability can be varied by one signal processing device.
By selectively switching between wideband reception processing and narrowband reception processing according to the operation purpose and operation status, it is possible to contribute to speeding up the reception processing.

In the above configuration, each of the plurality of receiving apparatuses has a filter set to a predetermined pass band. With this configuration, the signal processing device receives a reception signal of an arbitrary band from the wideband reception signal and performs reception of an arbitrary reception signal in the case of wideband reception in a state where a plurality of reception devices that cover a narrow band are connected. It is possible to obtain.
