式に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a system for switching between working and standby microwave transmitters, and particularly to a microwave transmitter for microwave communication lines in which a standby transmitter is in an operating state. Concerning a method for switching between active and standby transmitters.

ケとる構成となっていた。Conventionally, the working/standby switching system for microwave transmitters on this crosspiece has been to switch between one working transmitter (hereinafter referred to as the working unit) and one standby transmitter (hereinafter referred to as the pre-gRiso). 1 to 1
Is it an N-to-1 configuration with N working machines and 1 spare machine? The standby unit had a transmission output level almost the same as that of the active unit, and was configured to use a so-called hot standby switching system in which it stood by in an operating state.

ない。The above-mentioned method for switching between the working and standby microwave transmitters in the conventional microwave transmitter is a hot standby system in which the standby unit has almost the same transmission output level as the working unit. Since the configuration is such that when the current machine is in normal condition, there is a spare +! Although A does not substantially contribute to the operation of the communication circuit, it continues to be generated due to the transmitter output being equivalent to that of the active unit, and the power consumed by this standby unit is the same as that of the active unit when it is operating normally. There was a problem that most of the time when I was working, I wasted energy.〇Is this the problem? Therefore, one method that has been used in the past is the so-called cold standby switching method, in which the power to the standby unit is turned off while the active unit is operating normally, and the power to the standby unit is turned on when the active unit fails. However, it is hardly used in communication lines that require uninterrupted switching, such as microwave communication.

の少ない値となっている。In addition, due to the recent development of device technology, the reliability of micro liquid flow equipment has improved as mentioned above, and in the hot-spring switching system, the frequency of switching between the working and standby equipment is as low as once every 1 to 2 years. It has become.

なかった。The transmission output level should be set to about 30 to 40 dB higher than the transmission output required in a steady state where phasing does not occur, and the transmission 1N output of the standby unit should be maintained at the same level as the active unit. was not economical due to its nature as a spare machine.

By providing a method for switching between working and standby microwave transmitters, which can reduce power consumption without loss and increase cost by 1 kHz, the solution is to solve all the problems. The working/standby switching method of the microwave transmitter of the present invention is as follows:
Equipped with a working transmitter that transmits at a predetermined transmission output level and a standby transmitter that stands by in an operating state. In the working/standby microwave transmitter switching system, the standby transmitter is configured to have a lower transmission output level than the working transmitter.

In order to transmit to both the working and backup routes, the working transmitter 4 is split into two by the signal splitter 2 and transmits at a predetermined transmission output level n1.
The signal from this working transmitter 4 is inputted to the standby transmitter 3 which has a small transmission output level and is in operation. The switch 5 selects the normal transmission output of the active transmitter 4 or the standby transmitter 3 and sends it to the output terminal 6 depending on the transmission state of the transmitter 4 or the standby transmitter 3. When both the standby transmitter 3 and the working transmitter 4 are in normal operation, the configuration is such that the entire transmission output is sent to the output end 6 of the working transmitter 4, which has a higher transmission output level.
