Integrated Alarm Signal Display Device of Satellite Communication System Transceiver

摘要

The present invention relates to an integrated alarm signal display device of a satellite communication system transmitting / receiving terminal capable of integrally displaying an operation state of each RF module, and generating and outputting first and second oscillation frequency signals required for modulation and demodulation of a transmission / reception signal. In addition, the local oscillation circuit outputs an alarm signal of a first level according to whether the first and second oscillation frequency signals exceed the frequency tolerance range, and the power level of the uplink signal that is finally amplified and transmitted by a signal having a predetermined power level. An RF transmission / reception circuit of a satellite communication system having a transmission power detector for detecting an error and outputting an alarm signal of a second level when an abnormality occurs, comprising: a potential inverter for inverting the level of an alarm signal applied from the local oscillation circuit; In accordance with the second level alarm signal output from the potentiometer and the transmission power detector, each of them is turned on and off to operate abnormal operation state of the configuration. A light-emitting display unit for visual display, an OR operation unit composed of a plurality of diodes for performing an OR operation on the output signal of the potential inverter and the output signal of the transmission power detector, and a predetermined switching control according to the level of the detection signal calculated by the OR operation unit. And a relay for driving the alarm sound output unit by being turned on and off in accordance with a switching control signal outputted from the alarm condition determination unit.
