The Antenna Monitoring Unit is a device used to monitor the operating status and performance of antenna systems. Below is a detailed introduction to it:
Functions:
Power Monitoring: It can monitor the forward power and reflected power of the signals transmitted by the antenna.
Signal Strength Monitoring: It can monitor the Received Signal Strength Indicator (RSSI) level of the receiving channel to evaluate the quality of the signals received by the antenna.
Fault Localization: Some Antenna Monitoring Units are equipped with the fault localization function.
Environment and Status Monitoring: Some monitoring units can also monitor the environmental parameters and operating status of the antenna system.
Composition:
RF Signal Detection Module: It is used to receive the signals transmitted by the antenna and convert them into measurable electrical signals for subsequent processing, such as detecting the power of the signals.
Control Module: Modules like ARM modules, which usually include ADC (AnalogtoDigital Converter) and MCU (Microcontroller Unit), are responsible for collecting, processing and analyzing the data transmitted by the RF signal detection module, and can also control the operation of other modules.
Sensor Module: It may include a 6axis attitude angle sensor, etc. It is used to monitor the attitude information of the antenna, such as azimuth and elevation angle. It may also be equipped with environmental sensors to monitor environmental parameters like temperature and humidity.
Communication Module: Modules like WiFi communication modules and serial communication circuits are used to upload monitoring data to the control center or communicate with the upper computer, enabling operators to conduct remote monitoring and management.
Application Fields:
Communication Field: In mobile communication base stations, the Antenna Monitoring Unit can ensure the normal operation of the antenna, guarantee the stable transmission of signals, and improve communication quality.
Radio and Television Field: It is used to monitor the operating status of broadcast transmitting antennas and TV transmitting antennas, prevent signal interruption caused by antenna faults, and ensure the normal broadcast of programs.
Radar Field: Monitoring radar antennas helps ensure the accuracy and reliability of radar systems, detect antenna faults or performance changes in a timely manner, and ensure that radars can detect targets accurately.
