The first isolation transformer 21 is connected to the power supply line of the PAPI lamp. Specifically, the first-lamp monitor 2 is connected to the secondary circuit of the main power supply circuit through the secondary side of the first isolation transformer 21, and the primary side of the first isolation transformer 21 is connected to the main power line of the main power supply circuit. Each status monitor 1 is used to collect the angle value of the PAPI lamp light and the current of each light source in the PAPI lamp; the first-lamp monitor 2 is used to receive signals from the status monitor 1 and supply power to the status monitor 1.

[0052] The PAPI lamp system monitoring host computer 4 is connected to the second individual lamp monitor 3. The second individual lamp monitor 3 is connected to the second isolation transformer 31 to form a second circuit. The second isolation transformer 31 is connected to the power supply line of the PAPI lamp. Specifically, the second individual lamp monitor 3 is connected to the secondary circuit of the main power supply circuit through the secondary side of the second isolation transformer 31, and the primary side of the second isolation transformer 31 is connected to the main power line of the main power supply circuit. The second individual lamp monitor 3 receives signals from all the first individual lamp monitors 2 and transmits these signals to the PAPI lamp system monitoring host computer 4. The PAPI lamp system monitoring host computer 4 receives and displays the status signals of each PAPI lamp and issues an alarm signal when a PAPI lamp malfunctions.

[0053] Furthermore, each group of PAPI lights has three light sources, and each status monitor is equipped with three switchable current transformers and one angle sensor. Each switchable current transformer collects the current of each light source in a group of PAPI lights. The angle sensor is used to collect the installation angle value of the group of lights in real time for real-time angle monitoring. The angle sensor needs to be calibrated during installation to ensure consistency with the flight calibration angle of the PAPI lights.

[0054] Each status monitor 1 is connected to a first single-lamp monitor 2. The first single-lamp monitor 2 is a power line modem. The power line modem is connected to a first isolation transformer 21, which is used to receive the signal of the corresponding connected status monitor 1 and power the status monitor 1. When the first single-lamp monitor 2 is installed, it can be connected to the secondary circuit of the main power supply circuit through the secondary side of the first isolation transformer to realize the power supply of the status monitor 1 and the power line carrier coupling to the primary circuit, and to transmit PAPI lamp status data (real-time light source status and angle value).

[0055] The second lamp monitor 3 receives signals from all the first lamp monitors 2 and transmits them to the PAPI lamp system monitoring host computer 4. The second lamp monitor 3 is a power line modem connected to the secondary circuit of the main power supply circuit via the secondary side of the second isolation transformer 31.

The second single-lamp monitor 3 is used to receive the current data of the light source collected by the first single-lamp monitor 2 and transmit the data to the PAPI lamp system monitoring host computer 4. When no current is detected in the light source of the PAPI lamp, or when the measured angle value deviates from the set range and the data is abnormal, an alarm signal is issued.

[0056] The PAPI light system monitoring host computer 4 also periodically sends query commands for each group of PAPI lights to the second single-lamp monitor 3, converting the query commands into power line carrier signals and coupling them into the primary loop. The first single-lamp monitor 2 converts the power line carrier signals into digital signals and parses them. Upon receiving the query command, the first single-lamp monitor 2 converts the real-time light source status and angle data obtained from the status monitor 1 into power line carrier signals and couples them into the primary loop, then sends them back to the second single-lamp monitor 3. The second single-lamp monitor 3 parses the received PAPI light status data information and forwards it to the PAPI light system monitoring host computer 4 for display and alarm.

[0057] To ensure the normal operation of the lighting circuit, a PAPI lamp constant current dimmer 5 can be added to the PAPI lamp circuit to maintain a constant current value in the lighting circuit, ensuring normal airport operation and flight safety. The PAPI lamp status monitoring device provided by this invention is completely independent of existing PAPI lamp systems and can be used to monitor the status of different types of PAPI lamps.

[0058] In this embodiment, the isolation transformers (such as the first isolation transformer 21 and the second isolation transformer 31) in the PAPI lamp status monitoring device provide electrical isolation in each circuit. This allows data communication between low-voltage monitoring devices, such as status monitors, and high-voltage power supply lines without directly transmitting power surges or interference to the monitoring devices. This isolation protection prevents power fluctuations on the power lines from affecting data transmission, ensuring the safety of the monitoring equipment and the stability of the data. Each circuit in this status monitoring device can operate independently. The first circuit includes a status monitor, a first individual lamp monitor, and a first isolation transformer; the second circuit includes a PAPI lamp system monitoring host computer, a second individual lamp monitor, and a second isolation transformer. This structure allows each circuit to independently transmit and receive data, avoiding interference and impact on the entire system due to power fluctuations.

[0059] During installation, the status monitor is mounted at the tail of each group of PAPI lights. Each status monitor is equipped with three switchable current transformers and one angle sensor. The current transformers collect the current flowing through each light source in the PAPI lights, and the angle sensor is calibrated to match the flight angle of the PAPI lights, collecting angle values ​​in real time for real-time angle monitoring. The first individual light monitor is installed close to each group of PAPI lights, using an isolation transformer to power the corresponding status monitor. The first individual light monitor is installed in the circuit of the PAPI light it monitors. The second single-lamp monitoring device is located in the loop preceding all signals transmitted from the first single-lamp monitors. The front end of the second single-lamp monitoring device is connected to the PAPI lamp monitoring host computer. Communication between the PAPI lamp monitoring host computer and the second single-lamp monitoring device can be achieved via a 485 serial port. The PAPI lamp monitoring host computer is located in the lighting station, enabling real-time monitoring of the PAPI lamp system. When the PAPI lamp light source or angle is abnormal, the host computer will issue an alarm message, improving the timely detection of PAPI lamp failures to a certain extent. Its real-time capability enhances the runway's safe operation capability.
