Description

Technical Field

[0001] The invention relates to an aircraft windshield water vapor intrusion detection device and a detection method thereof. Background Art

[0002] The aircraft windshield is one of the important components to ensure the operation of the aircraft. It is mainly composed of outer tempered glass, middle interlayer and inner tempered glass. The middle interlayer is integrated with a circuit system for heating, deicing, anti-fogging and information feedback.

[0003] Due to the large temperature difference between high altitude and ground, moisture intrusion into the interlayer can easily condense, causing failures in the heating, de-icing, and anti-fogging circuits. Failures can cause arcing in the circuits, leading to localized overheating and, in severe cases, cracking of the windshield. Therefore, an effective method is urgently needed to promptly detect moisture intrusion on the windshield to ensure flight safety. Summary of the Invention

[0004] One of the purposes of the present invention is to provide an aircraft windshield water vapor intrusion detection device, which can quickly and efficiently detect whether the middle interlayer of the aircraft windshield is invaded by water vapor to ensure flight safety.

[0008] A second sensor is provided on the inner surface of the windshield and is used to monitor the humidity inside the windshield in the cab;

[0009] The controller includes a control module, an alarm module and a communication module. The control module is connected to the first sensor and the second sensor, and is used to calculate the difference between the humidity detection value of the first sensor and the humidity detection value of the second sensor, and compare the difference with a preset threshold of the control module. If the difference is greater than or equal to the preset threshold, an alarm is issued through the alarm module.

At the same time, historical data on windshield humidity can be obtained and used as data support for fault diagnosis.

[0013] The alarm module of the present invention adopts a sound alarm and a light alarm, and can quickly notify relevant personnel of the alarm information through the synchronous sound and light alarm.

[0014] A second object of the present invention is to provide a detection method using the aircraft windshield water vapor intrusion detection device, comprising the following steps:

[0017] S3. After a preset delay, repeat steps S1 and S2, and monitor in real time whether the middle layer of the windshield is invaded by water vapor in this cycle.

[0018] The present invention transmits the humidity detection value of the first sensor, the humidity detection value of the second sensor and the difference to the monitor through the communication module.

[0019] When the difference is greater than or equal to a preset threshold, the communication module of the present invention sends an alarm message to the crew and ground staff via SMS or email, so as to facilitate timely response and take necessary measures to ensure flight safety.

[0025] Explanation of reference numerals: 1 - first sensor, 2 - second sensor, 3 - controller, 4 - sound alarm, 5 - light alarm, 6 - communication module connection port. DETAILED DESCRIPTION

[0026] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can better understand and implement the technical solution of the present invention.

[0027] like Figure 1 As shown, an aircraft windshield water vapor intrusion detection device includes:

[0028] The first sensor 1 is provided at a connection port connected to the windshield interlayer. This connection port is an existing connection port for the heating, deicing, anti-fogging, and information feedback circuit system in the interlayer. Since it is connected to the space in the windshield interlayer, this connection port can be used to monitor the humidity in the windshield interlayer.

[0029] The second sensor 2 is provided on the inner surface of the windshield and is used to monitor the humidity inside the windshield in the cab;

[0030] The controller 3 includes a control module, an alarm module and a communication module. The control module is connected to the first sensor 1 and the second sensor 2, and is used to calculate the difference between the humidity detection value of the first sensor and the humidity detection value of the second sensor, and compare the difference with the preset threshold of the control module. If the difference is greater than or equal to the preset threshold, an alarm is issued through the alarm module. The communication module is used to transmit the humidity detection value of the first sensor, the humidity detection value of the second sensor, the difference and the alarm status of the alarm module to the monitor.

[0031] In one embodiment, the controller 3 is connected to the aircraft's data bus or flight control system, and the aircraft windshield moisture intrusion device is integrated with the aircraft system. By real-time monitoring and recording of windshield humidity data, data can be obtained in a timely manner for fault diagnosis, facilitating earlier discovery and resolution of windshield moisture intrusion problems. At the same time, historical data on windshield humidity can be obtained and used as data support for fault diagnosis.

[0032] See also Figure 1 The alarm module adopts a sound alarm 4 and a light alarm 5, and can quickly notify relevant personnel of the alarm information through sound and light synchronous alarm.

[0033] In one embodiment, the control module utilizes a microcontroller chip connected to a power supply. This microcontroller chip has pins for connecting to the first sensor 1, the second sensor 2, the sound alarm 4, and the light alarm 5. The chip is pre-programmed to collect sensor data, calculate the difference in humidity detection values, and compare the difference with a preset threshold. The control module can control the output level of the pins connected to the sound alarm 4 and the light alarm 5 through a digital lighting function. A high level triggers the alarm, while a low level disables the alarm. The controller 3 is provided with a communication module connector 6 for external data transmission.

[0034] like Figure 2 As shown, the detection method using the above-mentioned aircraft windshield water vapor intrusion detection device includes the following steps:

[0035] S1. The control module collects the humidity detection value of the first sensor and the humidity detection value of the second sensor at the same time, and calculates the difference between the humidity detection value of the first sensor and the humidity detection value of the second sensor;

[0036] S2. Comparing the difference with a preset threshold of the control module. If the difference is greater than or equal to the preset threshold, it is determined that moisture has invaded the middle layer of the windshield and an alarm is generated by the alarm module. If the difference is less than the preset threshold, the alarm module is deactivated. The preset threshold is an adjustable empirical threshold set based on the aircraft model and weather conditions. Using an adjustable preset threshold allows for humidity detection on various types of windshields.

[0037] S3. After a preset delay, repeat steps S1 and S2, and monitor in real time whether the middle layer of the windshield is invaded by water vapor in this cycle.

[0038] During the detection process, the humidity detection value of the first sensor, the humidity detection value of the second sensor, and the difference value may be transmitted to the monitor through the communication module.

[0039] When the difference is greater than or equal to a preset threshold, the communication module sends an alarm message to the crew and ground staff via SMS or email, so that they can respond in time and take necessary measures to ensure flight safety.

[0040] The present invention can also be further expanded, for example, by adding data reporting and remote access capabilities, storing test results and generating detailed data reports. Furthermore, remote access to the system via the internet or a data link allows for convenient viewing of historical windshield humidity data and monitoring of real-time test status. Alternatively, the windshield moisture intrusion detection device can be integrated with other aircraft systems, such as the flight control system and aircraft health monitoring system, to achieve more comprehensive aircraft status monitoring and fault diagnosis.

[0041] The above embodiments are only preferred embodiments of the present invention, but they cannot be used as limitations of the invention. Any modifications and improvements based on the concept of the present invention should fall within the scope of protection of the present invention. The specific scope of protection shall be subject to the claims.
