Detailed Description
The principles and features of the present invention are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
As shown in fig. 1-4, a novel broadcast transmitter switching system comprises four radio frequency U-shaped coaxial connectors, namely a radio frequency U-shaped coaxial connector 1, a radio frequency U-shaped coaxial connector 2, a radio frequency U-shaped coaxial connector 3, a radio frequency U-shaped coaxial connector 4, a coaxial switch 5 and a mounting panel 6; the four radio frequency U-shaped coaxial connectors are arranged on the same plane, the coaxial switch faces backwards, and the four ports of the coaxial switch are arranged opposite to the ports of the radio frequency U-shaped coaxial connectors. The four ports of the coaxial switch are respectively connected with the lower ports of the radio frequency U-shaped coaxial connector I1, the radio frequency U-shaped coaxial connector II 2 and the radio frequency U-shaped coaxial connector III 3 and the upper port of the radio frequency U-shaped coaxial connector IV 4. The radio frequency source A7 is connected with the upper port 11 of the radio frequency U-shaped coaxial connector I1, the radio frequency source B8 is connected with the upper port 11 of the radio frequency U-shaped coaxial connector III 3, the antenna 9 is connected with the upper port 11 of the radio frequency U-shaped coaxial connector II 2, and the dummy load 10 is connected with the lower port 12 of the radio frequency U-shaped coaxial connector IV 4. The distance between the upper opening 11 of the first radio frequency U-shaped coaxial connector 1 and the upper opening 11 of the second radio frequency U-shaped coaxial connector 2 is equal to the distance between the upper opening and the lower opening of each radio frequency U-shaped coaxial connector. The distance between the upper opening 11 of the third radio frequency U-shaped coaxial connector 3 and the upper opening 11 of the second radio frequency U-shaped coaxial connector 2 is equal to the distance between the upper opening and the lower opening of the third radio frequency U-shaped coaxial connector.
In one specific embodiment, the radio frequency U-shaped coaxial connector is made of brass, aluminum or polytetrafluoroethylene materials;
in another embodiment, the coaxial switch 5 is made of brass, aluminum or polytetrafluoroethylene.
The specific working process comprises the following steps:
when the coaxial switch 5 can work normally, the communication between the radio frequency source and the antenna 9 or the communication between the radio frequency source and the dummy load 10 can be switched by only controlling the rotation of the coaxial switch 5.
As shown in fig. 5, when the coaxial switch 5 fails and cannot be used normally, if the radio frequency source A7 is required to be communicated with the antenna 9, the radio frequency U-shaped coaxial connector 1 and the radio frequency U-shaped coaxial connector 2 are removed from the mounting panel 6, and the upper port and the lower port of the radio frequency U-shaped coaxial connector are respectively connected with the upper ports of the radio frequency U-shaped coaxial connector 1 and the radio frequency U-shaped coaxial connector 2 by using any one of the removed radio frequency U-shaped coaxial connectors, so that the radio frequency source A7 and the antenna 9 can be communicated by skipping the coaxial switch 5; if the radio frequency source B8 is required to be connected with the antenna 9, the radio frequency U-shaped coaxial connector III 3 and the radio frequency U-shaped coaxial connector II 2 are taken down from the mounting panel 6, any one of the taken down radio frequency U-shaped coaxial connectors is used, the upper port and the lower port of the radio frequency U-shaped coaxial connector are respectively connected with the upper port 11 of the radio frequency U-shaped coaxial connector III 3 and the upper port 11 of the radio frequency U-shaped coaxial connector II 2, and the coaxial switch 5 can be skipped to communicate the radio frequency source B8 with the antenna 9. The coaxial switch can be maintained or replaced under the condition that normal broadcasting is not affected.
Through the technical scheme, when the coaxial switch can work normally, the transmitter and the antenna or the connection between the transmitter and the dummy load can be switched by only controlling the rotation of the coaxial switch. When the coaxial switch cannot work normally, the normal operation of the broadcasting system can be ensured only by changing the installation position of the radio frequency U-shaped coaxial connector, and the coaxial switch can be maintained or replaced under the condition that normal broadcasting is not affected.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
