In conventional portable microwave transmitters,
Input signal switching is performed when the high frequency section is operated as a single high frequency section.
The method was to switch the intermediate frequency input sent from the transmission control section to the signal input to the high frequency section.
For this reason, the state in which the transmission control section and the high frequency section are connected is not practical due to operational and quality aspects of the transmitted signal. In the present invention, when the input switching operation is performed in the transmission control section, this switching information is transmitted to the high frequency section, and the input signal to the high frequency section is transmitted,
Based on the switching information, the input signal is switched to the high frequency section, and the control section cuts off or attenuates the input signal from the control section so that the input signal to the control section is not sent to the high frequency section. This is how it was done. According to the present invention, it is possible to switch the inputs of the transmission control section and the transmission high frequency section with good operability and without deteriorating the quality of the transmitted signal, and the operating range of the device is expanded.

FIG. 2 is a block diagram showing the overall configuration of the prior art. In the figure, the input signal of the control section is the modulator
(A) It is modulated by 5 and becomes an intermediate frequency signal. On the other hand, control signals such as channel switching are converted into serial signals by a parallel-to-serial converter 3, modulated by a modulator (B) 4 together with other communication intercom signals, and frequency-multiplexed into the aforementioned intermediate frequency signal by a mixer 6. be done. An intermediate frequency signal, a modulated wave, and a power source for the high frequency section (not shown) are supplied to the high frequency section via the coaxial cable 7.

より中間周波信号は所定のチヤンネルのマイクロ
波帯電波として、パラボラアンテナより放射され
る。 In the high frequency section, a separator 8 separates an intermediate frequency signal and a modulated wave, and the intermediate frequency signal is supplied to a modulator (C) 13 via a switch 11. On the other hand, the modulated wave is demodulated by a demodulator 9 to obtain a control signal serially converted to the communication intercom signal. The serially converted control signal is further converted into the original control signal in the serial/parallel converter 10 to control the local oscillator 14. As a result, the intermediate frequency signal is radiated from the parabolic antenna as a microwave radio wave of a predetermined channel.

換える。 If you want to send out the signal input to the high frequency section, manually operate the switch 11 to cut off the intermediate frequency signal supplied from the control section via the separator 8, and send it to the modulator ( A) Switch to the 12 side.
変調器(A)１２は高周波部に供給されている入力
信号を変調するもので、制御部から送り込まれて
いた中間周波信号に相当する信号となる。 The modulator (A) 12 modulates the input signal supplied to the high frequency section, and becomes a signal corresponding to the intermediate frequency signal sent from the control section.
本来、この切換え機能は、高周波部のみ単体で
運用するために設けられているものである。この
ため、制御部と高周波部が同軸ケーブルで接続さ
れたまゝの状態で入力信号を高周波部に切換えて
も、制御部からの中間周波信号の漏れ込みがある
ため、ビート現象が発生して実用に供給すること
ができない。 Originally, this switching function was provided to operate only the high frequency section alone. Therefore, even if the input signal is switched to the high frequency section while the control section and the high frequency section are still connected by a coaxial cable, the intermediate frequency signal leaks from the control section, resulting in a beat phenomenon that is not practical. cannot be supplied.

との入力信号の切換えを行うことが困難である。
As mentioned above, in the conventional technology, it is not practical to switch the input signal on the high-frequency section side when the control section and the high-frequency section are connected, and there are also constraints on the arrangement of the two devices (microwave line-of-sight transmission). Therefore, the control section is installed in a low place and the high frequency section is installed in a high place, and during operation, an operator is usually on standby on the control section side, and the high frequency section is unmanned.) Therefore, in reality, the control section and high frequency section are It is difficult to switch the input signal to and from the

ケーブル７をとりはずさなければならなかつた。 Therefore, in order to send out a signal directly input to the high frequency section, it is necessary to manually switch the switch 11 in the high frequency section and disconnect the cable 7 from the control section.

In order to achieve the above object, the present invention obtains an input switching control signal using a switch provided on the control section side, and transmits this switching control signal from the control section to the high frequency section using the same means as other control signals. However, the input signal switching means in the high frequency section is driven.

るようにする。 Furthermore, when switching to a high frequency section input signal, the intermediate frequency signal is cut off or attenuated on the control section side so as not to be influenced by the intermediate frequency signal from the control section.
At the same time, like the conventional function, the high frequency section is also provided with the function of manually switching between the intermediate frequency signal and the high frequency section input signal, considering the standalone operation of only the high frequency section.

As a result, switching between the input signals of the control section and the high frequency section can be performed at any time on the control section side where the operator is waiting.

合、同様な手順を経て切換器１１′は制御部から
送出される中間周波信号に切換わる。 This operation will be explained below. Now, when it is desired to switch the input signal to the high frequency section side, the control signal selected by the input changeover switch 1 drives the switch 2 to cut off the intermediate frequency signal of the control section. On the other hand, the input switching signal is converted into a serial control signal by the parallel to serial converter 3 at the same time as the channel switching signal. Furthermore, this serial control signal is modulated by a modulator 4 together with the intercom signal. The modulated serial control signal and intercom signal, ie, the control communication signal, are transmitted to the high frequency section via a coaxial cable 7 via a mixer 6. (If the input signal to the control unit is selected, the modulated serial control signal is mixed with the intermediate frequency signal from the modulator (A) 5 by the mixer 6, frequency-multiplexed, and transmitted. ) The received control communication signal is demodulated into a demodulator serial control signal and an intercom signal via a separator 8.
The demodulated serial control signal is decoded by the serial/parallel converter 10, and the input switching signal, which is one of its control outputs, operates so that the switch 11' switches to the high frequency part input signal. When switching to the control section input, the switch 11' switches to the intermediate frequency signal sent from the control section through a similar procedure.
