Broadcast transmitter switching device and switching method thereof

Abstract

The invention discloses a broadcast transmitter switching device and a switching method thereof. The switching device comprises a mechanical carrier and a control unit, the mechanical carrier comprises a cabinet body, a resistor body framework and a fan support are arranged on the lower portion in the cabinet body, a first resistor body and a second resistor body are arranged on the resistor body framework, a first fan and a second fan are arranged on the fan support, a first partition plate is arranged on the upper portion of the resistor body framework, and an external interface board is arranged on the first partition plate. The upper part of the cabinet body is provided with a second separator plate, the upper part of the second separator plate is provided with a coaxial converter, the lower part of the second separator plate is provided with an emergency support, the cabinet body is provided with a front door and a rear door, a front door panel is provided with a switch, an indicating lamp and a high-frequency power meter, and an external interface board and the emergency support are arranged at the inner side of the rear door. The method can be effectively applied to switching of broadcast transmitters, stable and efficient switching among the host, the standby, the transmitting antenna and the dummy load can be realized, and the method is stable and reliable in performance, wide in market prospect and convenient to popularize and use.

Description

technical field

[0001] The invention belongs to the technical field of broadcast transmission, and in particular relates to a broadcast transmitter switching device and a switching method thereof. Background technique

[0002] According to the layout of the national radio and television policy, all cities above the prefecture-level city in my country should build medium-wave broadcasting transmitting stations, plus the number of relay stations exceeds a thousand. Medium wave broadcast transmitters are basically selected with a power level of 10kW. In order to ensure uninterrupted broadcasting, the broadcast transmitter is configured with one main machine and one standby machine. The main and standby machines share a dummy load and a pair of antennas. Switching between the host, standby, antenna, and dummy load has poor stability, reliability, and degree of automation. Remote computer programming control and unattended cannot be realized yet. The number of feeder pipes and el...
