Abstract

PURPOSE:To miniaturize the transmitter by using a detection signal of a returned wave in the transmitter installed mainly in a skyscraper so as to change over an active transmission system into a standby transmission system thereby preventing a line disconnection due to a window wiping gondola. CONSTITUTION:A transmission signal inputted to a transmission input terminal 1 is branched and inputted to the 1st transmitter 3 and the 2nd transmitter 4. When a window wiping gondola descends in from face of the 1st transmission antenna 7, a radio wave irradiated from the antenna 7 is reflected, then a reflection detector 5 detects the returned wave from the antenna 7. The controller 6 applies control by using the detection signal to stop the transmission of the 1st transmitter 3 and to start the transmission of the 2nd transmitter 4.

In recent years, with the advanced development of devices, wireless communication equipment in the millimeter wave band has become increasingly integrated into ICs, making them smaller and lighter. In addition, because antennas in this band are becoming smaller, the antenna and radio equipment have been integrated into a single unit, making it easier to install indoors, even though the antenna, tower, and radio station building used to be installed. Therefore, the wireless transmitter is usually installed next to a window in order to have a line of sight to the other station.

In the conventional wireless transmitter described above, when a window cleaning gondola comes down from the roof of a building and comes to rest in front of the transmitting antenna, the time it takes to stay stationary for this window cleaning is relatively short, but it can be used at high speeds. On a line that transmits data day and night, the transmitted waves no longer reach the other party, resulting in a line break. In particular, the users of the building and the wireless transmitter are often different, so if there are many companies in one building, it is not possible to control the movement of the window cleaning gondola according to the specific company. There were some problems, such as not being able to get there.

Next, the operation of the wireless transmitter with the above configuration will be explained. First, the transmission signal input to the transmission input terminal 1 is split by the distributor 2, and then sent to the first transmitter 3 and the second transmitter 4.
Enter. If the window cleaning gondola is not coming down in front of the first transmitting antenna T, the reflected wave detector 5
Since there is no return wave from the transmitting antenna T, no detection signal is output. Therefore, the controller 6 does not output the full control signal, so the first transmitter 3 is in the operating state, and the second transmitter 4! ri becomes inactive. Therefore, after converting the transmission signal inputted into the first transmitter into the required frequency and power, the signal is transmitted from the first transmitting antenna T via the reflected wave detector 5. Next, when the window cleaning gondola descends in front of the first transmitting antenna 7, the radio waves emitted from the first transmitting antenna 7 are reflected by the window cleaning gondola. Therefore, the reflected wave detector 5 detects the return wave from the first transmitting antenna 7 and outputs a detection signal. Therefore, the controller 6 performs a control operation based on the input of this detection signal, and stops the transmitting operation of the first transmitter 3 and starts the transmitting operation of the second transmitter 4. therefore,
After converting the transmission signal input to the second transmitter 4 into the required frequency and power, the transmission signal is transmitted to the second transmitting antenna 8.
It can be sent from.
