Description

Technical Field

[0001] The present invention particularly relates to a transmitter antenna feed over-temperature protector. Background Art

[0002] In radio and television transmission stations, high-power antenna and feed systems are critical for ensuring safe broadcasting. Their primary function is to efficiently transmit the high-frequency signal output by the transmitter to the antenna, which then radiates it into the air. However, over long-term operation, antenna and feed systems are susceptible to various factors, leading to performance degradation or even failure. Common problems include loose connectors, aging components and seals, damaged feed tubes, and water immersion. These issues not only affect signal transmission quality but can also lead to increased reflected power, abnormal standing wave ratios, and even damage core components such as the transmitter's power amplifier tubes, resulting in prolonged broadcast suspensions and serious consequences.

[0003] Currently, while some devices can monitor some parameters of antenna feeder systems, these devices typically only monitor the overall status of the antenna feeder system and cannot accurately monitor temperature changes at each node in the antenna feeder system link. Furthermore, when these devices detect an anomaly, they often only issue simple alarm signals and are unable to implement appropriate protective measures based on the specific fault condition. Therefore, there is a lack of equipment that can monitor the temperature of each node in the antenna feeder system link in real time and take timely protective measures when abnormal temperature rises occur.

[0004] In recent years, with the advancement of fiber-optic sensing technology, distributed temperature sensing (DTS) systems have been increasingly adopted across various industrial sectors. These systems utilize optical fibers as sensors, acquiring temperature information by measuring changes in optical signals within the fibers. DTS systems offer advantages such as long measurement distances, high accuracy, fast response speeds, and strong resistance to electromagnetic interference, making them particularly suitable for high-power transmitters operating in complex electromagnetic environments. However, applying DTS systems to temperature monitoring in antenna feeder systems and enabling coordinated control with transmitters remains a technological gap. Summary of the Invention

[0036] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0037] Figure 1 It is a schematic diagram of a transmitter antenna feed over-temperature protector of the present invention. DETAILED DESCRIPTION

[0038] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0039] The transmitter antenna feed over-temperature protector of the present invention is composed of a distributed optical fiber temperature sensing system through temperature-sensitive optical fiber and detectors, which mainly monitors the temperature status of node areas such as the upper and lower half antenna power splitters, feeder lines, and feeder pipes on the high-power antenna feed line. Figure 1 As shown, a transmitter antenna feed over-temperature protector of the present application includes a main control unit, a switching power supply, a human-machine interface, a TCP / IP interface, an RS232 interface, a temperature-sensing optical fiber and a detector.

[0040] The temperature-sensing optical fiber is securely fastened along the transmitter antenna feeder cable, maintaining good contact with the antenna. A detector, connected to one end of the fiber, collects temperature data at each measurement point. The close attachment of the fiber ensures accurate and sensitive temperature measurement. Good contact reduces heat transfer delays, enabling the detector to collect temperature data from each measurement point promptly and accurately.

[0041] The human-machine interface includes but is not limited to LCD display, buttons, indicator lights and switches.

[0042] The main control unit connects to the switch and communicates with the detector via a TCP / IP interface, reading the temperature values at each measurement point in real time. It also communicates with the transmitter master control and sends control commands to shut down or reduce the transmission power based on the temperature rise. The main control unit also features a data calibration function to eliminate temperature deviations caused by factors such as transmission delays in the temperature-sensing optical fiber and measurement errors in the detector. It also uses a filtering algorithm to process temperature data to reduce noise interference and improve data stability. The main control unit stores the processed temperature data in real time on a local storage device, performs regular data backups, and uploads the data to a remote monitoring center via the network, enabling centralized data management and sharing.

[0043] The main control unit's data calibration and filtering algorithm effectively improve the accuracy and reliability of temperature data. Through real-time storage and data backup, the protector ensures data integrity, facilitating subsequent fault analysis and system maintenance. Data is uploaded to a remote monitoring center, allowing maintenance personnel to remotely monitor the antenna system's temperature status and promptly identify and address potential issues.

[0044] In the embodiments of this application, temperature-sensing optical fibers are densely distributed at key locations along the antenna feeder system, such as joints, bends, antenna power splitters, feeder lines, and feeder pipes, to improve temperature monitoring accuracy and sensitivity. For example, a 1-meter-long section of temperature-sensing optical fiber is placed on both sides of each joint, with temperature measurement points set every 0.5 meters. Around the antenna power splitter, temperature-sensing optical fibers are arranged at 0.2-meter intervals, forming a dense temperature measurement grid. A detector is connected to one end of the temperature-sensing optical fiber to collect temperature data at each measurement point. The detector features high-precision temperature measurement capabilities, with a resolution of 0.01°C and an accuracy of 0.1°C. It also measures ambient temperature and provides reference temperature data. The detector communicates with the main control unit via a network communication interface and protocol. The main control unit collects temperature data in real time at set intervals and, by combining OTDR (Optical Time Domain Reflectometry) technology with Raman scattering characteristics, accurately locates temperature anomalies. This dense distribution ensures precise monitoring of key areas of the antenna feeder system, enabling timely detection of localized temperature anomalies. The detector's high-precision measurement capability and ambient temperature measurement function enable the protector to accurately measure temperature changes and calculate temperature rise based on the ambient temperature, thereby more accurately judging temperature anomalies.

[0045] By injecting light pulses into the optical fiber and measuring the time delay of the reflected light, the OTDR can accurately determine the location of the breakpoint or loss point in the optical fiber. The Raman scattered light characteristic is a temperature measurement technology based on light scattering. By measuring the intensity change of the Raman scattered light in the optical fiber, the temperature distribution along the optical fiber can be obtained. In the present invention, the main control unit combines the OTDR technology and the Raman scattered light characteristic to achieve accurate monitoring of the temperature of each node in the antenna feeder system link. Specifically, the detector measures the reflection time of the light pulse in the optical fiber through the OTDR technology to determine the specific location of the temperature anomaly in the optical fiber. At the same time, the temperature distribution along the optical fiber is measured through the Raman scattered light characteristic to obtain the temperature value of each temperature measurement point. The main control unit conducts a comprehensive analysis of the data of the two technologies to accurately determine the location of the temperature anomaly, thereby achieving early warning and precise positioning of antenna feeder system failures.

[0046] OTDR technology provides precise location information for temperature anomalies, while Raman scattering provides detailed data on temperature distribution. The combination of these two technologies enables the protector to not only quickly locate faults but also accurately measure temperature changes, providing strong support for early warning and precise fault location.

[0047] In the implementation mode of the present application, the main control unit is connected to the switch and the transmitter main control via the TCP / IP interface for communication. It can set the multi-level alarm threshold of the temperature rise, trigger the corresponding alarm level according to different temperature rise conditions, and realize remote monitoring and control through RS232, TCP / IP and other interfaces. Specifically, when the main control unit triggers the pre-alarm, yellow alarm or red alarm, the alarm status is displayed through the panel indicator light, and can be sent to the remote monitoring device through the RS232 and TCP / IP interfaces to remind maintenance personnel to pay attention to the temperature status of the antenna feed system. The multi-level alarm mechanism enables the protector to take corresponding measures according to different temperature rise conditions, which not only avoids unnecessary equipment shutdowns due to false alarms, but also can take protective measures in time when a fault occurs. Through the panel indicator light and the alarm display of the remote monitoring device, maintenance personnel can promptly understand the temperature status of the antenna feed system and conduct troubleshooting and processing in a timely manner.

[0048] In an embodiment of the present application, when a yellow or red alarm is triggered, the main control unit sends a power reduction command or a transmission power shutdown command to the transmitter, requesting the transmitter to adjust its power output to reduce the temperature of the antenna system and prevent further deterioration of the fault. When a red alarm is triggered, the main control unit records detailed alarm information, including the alarm time, alarm level, and the location of the temperature anomaly point, to facilitate subsequent fault analysis and processing. This automatic control function enables the protector to take quick action when a fault occurs, reducing the impact of the fault on the equipment. Detailed alarm information records provide an important basis for subsequent fault analysis and processing, helping maintenance personnel quickly locate and resolve problems.

[0049] In the implementation of the present application, the main control unit is equipped with an intelligent early warning algorithm. By learning and analyzing historical temperature data, it automatically identifies the temperature change pattern of the antenna feed system under normal operating conditions, as well as the temperature anomaly characteristics before a fault occurs. When a temperature change similar to a known fault pattern is detected, an early warning signal is issued to achieve early warning of antenna feed system failure. By learning and analyzing historical data, the intelligent early warning algorithm can automatically identify normal and abnormal temperature change patterns, thereby issuing a warning signal in advance. The application of this algorithm improves the early warning capability of the protector, allowing maintenance personnel to take preventive measures before a fault occurs, reducing the probability of failure.

[0050] To further enhance system reliability and fault tolerance, the main control unit utilizes a redundant design strategy. The main control unit is equipped with a backup device. In the event of a primary device failure, the system automatically switches to the backup device, ensuring normal system operation. The communication link utilizes dual network interfaces or backup communication lines to prevent data transmission interruptions caused by a single communication link failure, which could impact early warning and control functions. The redundant design ensures that in the event of a primary device or communication link failure, the system automatically switches to the backup device or line, ensuring continuity of monitoring and control functions. This design enhances system reliability and fault tolerance, ensuring the safe operation of the antenna and feeder system.

[0051] In the implementation mode of the present application, the main control unit is integrated with other monitoring systems of the radio and television transmission station to achieve information sharing and collaborative work. The main control unit comprehensively analyzes the temperature monitoring data with the power monitoring of the transmitter, the standing wave ratio monitoring of the antenna system and other data to more comprehensively understand the operating status of the antenna system. The main control unit also has an integrated interface with other systems to achieve automatic diagnosis and processing of antenna system faults, thereby improving the automation level and operating efficiency of the station. System integration enables the main control unit to share data with other monitoring systems and achieve collaborative work. By comprehensively analyzing multiple monitoring data, the main control unit can have a more comprehensive understanding of the operating status of the antenna system, thereby more accurately determining the cause of the fault. This integration also improves the automation level of the station, reduces manual intervention, and improves operating efficiency.

[0052] In the embodiments of this application, the main control unit has remote control and intervention capabilities, enabling remote control and intervention of the protector via the network. These functions include adjusting alarm thresholds, controlling transmitter power output, and remotely resetting the protector. The main control unit also has an automatic notification function. When an alarm occurs, it automatically notifies maintenance personnel via text message, email, or other means, ensuring that the fault is promptly addressed. This remote control and intervention function allows maintenance personnel to operate remotely from the equipment, improving maintenance flexibility and efficiency. The automatic notification function ensures that maintenance personnel receive alarm information promptly and take timely action to address the fault.

[0053] In the implementation of the present application, the main control unit has a fault detection and processing function. When a yellow alarm or red alarm is triggered, maintenance personnel can quickly locate the fault point based on the temperature anomaly location information provided by the protector. The antenna feeder system's connectors, components, and feeder pipes are checked for looseness, aging, damage, water immersion, and other issues. The fault detection and processing function allows maintenance personnel to quickly locate the fault point based on the detailed information provided by the protector, allowing for timely inspection and repair. This function reduces troubleshooting time and improves maintenance efficiency.

[0054] The main control unit also features a fault analysis and logging function, recording the cause, handling process, and results of a fault in a maintenance log. It also automatically records detailed fault information, including the time of occurrence, location of the temperature anomaly, temperature rise, alarm level, and corrective action. This function provides maintenance personnel with detailed fault information, facilitating subsequent fault analysis and system improvements. This detailed record helps analyze lessons learned, optimize maintenance strategies, and improve system reliability.

[0055] In the implementation mode of the present application, the main control unit has the function of system optimization and improvement. By introducing intelligent early warning algorithms, redundant designs, and integration technologies with other systems, the accuracy and reliability of early warnings are improved, the reliability and fault tolerance of the system are improved, and the automation level and operating efficiency of the system are enhanced. The main control unit also has self-learning and adaptive functions. According to the actual operation of the antenna feed system, it automatically adjusts the alarm threshold and early warning strategy to adapt to different working environments and operating conditions. The system optimization and improvement function enables the protector to continuously adapt to the operating changes of the antenna feed system, improving the accuracy and reliability of early warning and protection. The self-learning and adaptive functions enable the protector to automatically adjust parameters according to the actual operating conditions, further improving the intelligence level of the system.

[0056] Through the above detailed technical solutions and implementation methods, the transmitter antenna feed over-temperature protector of the present invention can effectively monitor the temperature status of the antenna feed system, issue early warning signals in a timely manner, and take corresponding protection measures according to different fault conditions, effectively preventing damage to the transmitter and ensuring the safe broadcasting of radio and television.
