Description

Technical Field

[0001] This application relates to the technical field of airport construction auxiliary equipment, and in particular to a portable protective light fence for airports. Background Technology

[0002] As a crucial hub for air transport, the safe operation of airports is increasingly important. During subsequent equipment maintenance and construction work involving either shutdown or non-shutdown operations, the entry of personnel and vehicles needs to be controlled for safety reasons. Currently, this is achieved through manual installation of safety barriers. Given the limited time available for entry, the time required for installing these barriers significantly reduces actual maintenance and construction time, increasing equipment maintenance costs. Utility Model Content

[0003] To address the problem that airports rely on manually installing protective barriers to control personnel and vehicles during maintenance, which significantly reduces maintenance and usage time, this application provides a portable protective light barrier for airports.

[0004] This application provides a portable protective light barrier for airports, which adopts the following technical solution:

[0005] A portable protective light fence for airports includes a lamp housing, which houses a laser emitting module, a control module, a warning module, and a power supply module. The lamp housing has a light projection port at the laser emitting end of the laser emitting module.

[0006] The laser emitting module is electrically connected to the control module and is used to project a linear laser beam to form a visual warning zone.

[0007] The warning module is electrically connected to the control module. The warning module includes an infrared sensing device and an alarm. The infrared sensing device is installed on the laser emitting module and the signal detection end of the infrared sensing device faces the light projection port. The infrared sensing device is used to detect whether there is a person or object in the visual warning zone to form a corresponding detection signal and to feed back the detection signal to the control module in real time.

[0008] The control module is used to generate an alarm signal when the detection signal changes, and drive the alarm to sound an alarm. The alarm is installed on the outer wall of the lamp housing.

[0009] The power supply module is electrically connected to the control module, the laser emitting module, and the warning module, respectively, and is used to supply power to the control module, the laser emitting module, and the warning module.

[0010] By adopting the above technical solutions, visual warning tape can effectively replace traditional protective barriers, enabling rapid deployment and removal, thereby significantly improving airport maintenance and construction efficiency and reducing labor costs. Infrared sensing equipment monitors people and objects within the visual warning tape in real time, ensuring the safety of the construction area. Simultaneously, the timely alarm function of the alarm system can quickly alert relevant personnel to take measures to avoid potential safety hazards. This improves the safety management level of airport construction sites, reduces the time wasted on manually deploying protective barriers, and provides more efficient protection for airport operations.

[0011] Preferably, it also includes a remote control module, which includes a signal receiver embedded in the lamp housing and a wireless signal module fixedly installed in the lamp housing. The wireless signal module is electrically connected to the signal receiver and is also electrically connected to the control module.

[0012] By adopting the above technical solution, the addition of the remote control module enables operators to remotely control the light barrier via wireless signals. This allows them to start, stop, or adjust parameters without being physically present on-site, significantly improving the ease and flexibility of equipment use. The combined use of the signal receiver and wireless signal module ensures accurate reception and transmission of remote commands, enhancing the equipment's intelligence level and providing strong support for safety management at the airport construction site.

[0013] Preferably, an anti-tipping module is also fixedly installed inside the lamp housing. The anti-tipping module is electrically connected to the control module and is used to generate a power-off control signal and transmit it to the control module when the lamp housing tilts. The control module disconnects the power supply to the laser emitting module according to the power-off control signal.

[0014] By adopting the above technical solution, the anti-tipping module can promptly generate a power-off control signal when the lamp housing tilts. The control module then quickly cuts off the power supply to the laser emitting module based on this signal. When the lamp body tilts and collapses in all directions, the internal switch of the tilt protection module is triggered, thereby cutting off the circuit. This is primarily used to prevent the equipment from continuing to emit light while tilted or leaning, thus avoiding impact on pedestrians and aircraft and causing laser pollution. Simultaneously, the tilt-off power-off mechanism eliminates potential circuitry hazards, enhancing safety.

[0015] Preferably, a mounting groove is provided on the side wall of the bottom plate of the lamp housing, and a flexible structure is fixedly installed in the mounting groove. The flexible structure includes a mounting block and at least two flexible tabs. One side of each flexible tab is fixedly connected to the side wall of the mounting groove, and the other side of each flexible tab is fixedly connected to the mounting block. A mounting hole is provided on the mounting block.

[0016] By adopting the above technical solution, a flexible structure is installed at the bottom of the lamp housing, and the entire grating is fixedly installed through the mounting block of the flexible structure. When the grating is subjected to external impact, the flexible piece breaks, thereby preventing the grating from damaging the aircraft.

[0017] Preferably, a fault detection module connected between the power supply module and the laser emitting module is also fixedly installed inside the lamp housing, which is used to detect the current value of the laser emitting module and feed it back to the control module in real time;

[0018] The fault detection module is also electrically connected to the control module, which is further used to generate a warning signal when the current value is greater than a preset current threshold and drive the alarm to sound an alarm.

[0019] By adopting the above technical solution, the fault detection module can monitor the current value of the laser emitting module drive circuit in real time. When the current of the laser emitting module drive circuit is too large, it indicates that the laser emitting module is not working properly. The alarm will then be triggered to alert the staff, preventing the laser emitting module from being damaged due to overcurrent. This improves the stability and safety of the equipment. At the same time, the timely alarm function helps to quickly locate and handle faults, reducing maintenance costs.

[0020] Preferably, a support frame is also fixedly installed inside the lamp housing, the power module is fixedly installed on the support frame, and a limit baffle is fixedly installed on the support frame at the location of the power module.

[0021] By adopting the above technical solution, the power module is fixedly installed inside the lamp housing by the support frame, which can effectively improve the installation stability of the power module and prevent the power module from loosening or being damaged due to vibration or movement of the lamp housing. At the same time, the setting of the limit baffle further limits and protects the power module, preventing it from shifting or falling off the support frame, thereby ensuring the stable operation and safety of the entire light fence.

[0022] Preferably, a communication module electrically connected to the control module is also fixedly installed inside the lamp housing for communicating with the airport remote monitoring center to transmit the warning signal and / or the alert signal to the airport remote monitoring center.

[0023] By adopting the above technical solution, the communication module enables real-time communication between the portable optical fencing and the airport's remote monitoring center. When an abnormal situation occurs within the restricted area, warning signals or alerts generated by a malfunction in the laser emission module can be promptly transmitted to the airport's remote monitoring center, facilitating rapid response and handling by management personnel and improving the safety management level of the airport construction site.

[0024] Preferably, a solar panel is fixedly installed on the outer wall of the housing, and the solar panel is connected to the power module.

[0025] By adopting the above technical solution, the installation of solar panels can effectively utilize the solar energy resources in the airport environment, providing additional power to the power module. This not only reduces reliance on traditional power sources but also lowers the energy consumption cost of the equipment, improving the environmental performance and endurance of portable optical fencing for airports. Specifically, the connection between the solar panels and the power module ensures stable operation of the equipment even during long-term operation or when far from a power supply, enhancing the equipment's portability and adaptability.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. A visual warning zone is formed by projecting a linear laser beam through a laser emitting module, replacing the traditional manually arranged physical guardrails. This significantly shortens the setup time of the warning zone, improves the efficiency of construction and maintenance work, and reduces equipment maintenance costs.

[0028] 2. By using infrared sensing equipment to detect in real time whether there are people or objects within the visual warning zone, and by promptly issuing an alarm, intelligent monitoring of the construction area is achieved, effectively improving the safety of the construction site;

[0029] 3. The power supply module provides stable power to each functional module, ensuring the normal operation of laser emission, signal detection and alarm functions, thereby guaranteeing the reliability and continuity of the entire system. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0036] This application discloses a portable protective light fence for airports.

[0037] Reference Figure 1 and Figure 2 A portable protective light barrier for airports includes a lamp housing 1. The lamp housing 1 houses a laser emitting module 3, a control module 2, a warning module 4, a power supply module 5, a remote control module 6, an anti-tipping module 7, a fault detection module 9, and a communication module 10. The power supply module 5 is electrically connected to the laser emitting module 3, control module 2, warning module 4, remote control module 6, anti-tipping module 7, fault detection module 9, and communication module 10 to supply power to each module and ensure their normal operation. The input terminal of the communication module is electrically connected to the output terminal of the control module 2, and the output terminal of the communication module is electrically connected to the input terminal of the control module 2. The control module 2 communicates with the airport remote monitoring center through the communication module to transmit information about the light barrier to the airport remote monitoring center for real-time monitoring of the status of each light barrier.

[0038] Reference Figure 2 The power module 5 is fixedly installed in the lamp housing 1. In order to ensure the stability of the power module 5 in the lamp housing 1, a support frame 51 is fixedly installed in the lamp housing 1. The power module 5 is fixedly installed on the support frame 51, and a limit baffle 52 is fixedly installed on the support frame 51 at the position of the power module 5. The limit baffle 52 limits the position of the power module 5 and ensures that the power module 5 will not shake in the lamp housing 1.

[0039] Reference Figure 2The laser emitting module 3 is fixedly installed inside the lamp housing 1. A projection port 11 is provided at the emitting end of the laser emitting module 3. The laser emitting module 3 projects a linear laser beam through the projection port 11 to form a visual warning strip. The input end of the laser emitting module 3 is electrically connected to the output end of the control module 2, so that the working state of the laser emitting module 3 can be controlled by the control module 2. In this embodiment, to ensure that the visual warning strip projected by the laser emitting module 3 is easily detected, the laser emitting module 3 can be installed on the top of the lamp housing 1, and the corresponding projection port 11 is located on the top of the lamp housing 1. The laser emitting module 3 can use a green laser such as CNI Laser MGL-III-532 or Laserglow GL-200, a red laser such as Thorlabs LP650-SF15, or a multi-line laser such as Laser Components LG3-650.

[0040] Reference Figure 2 The warning module 4 includes an infrared sensor 41 and an alarm 42. The infrared sensor 41 is detachably and fixedly installed on the laser emitting module 3, and the signal detection end of the infrared sensor 41 is installed facing the projection port 11. That is, the infrared sensor 41 can perform real-time detection within the detection range through the projection port 11 to determine whether a person or object has entered the detection range of the infrared sensor 41. In this embodiment, the infrared sensor 41 is used to monitor whether a person or object has entered the visual warning line projected by the laser emitting module 3. That is, the infrared sensor 41 does not necessarily have to be installed on the laser emitting module 3. It is only necessary for the signal detection end of the infrared sensor 41 to be installed in the same direction as the emitting end of the laser emitting module 3. The alarm 42 is fixedly installed on the outer wall of the lamp housing 1 so that it can be easily detected when a warning signal is generated.

[0041] Reference Figure 2The input terminal of the infrared sensing device 41 is electrically connected to the output terminal of the control module 2, so that the working state of the infrared sensing device 41 can be controlled by the control module 2. The output terminal of the infrared sensing device 41 is electrically connected to the input terminal of the control module 2, so that the detection signal generated by the infrared sensing device 41 in real time detection within the visual warning zone can be transmitted to the control module 2 in real time. The input terminal of the alarm 42 is electrically connected to the output terminal of the control module 2, so that the working state of the alarm 42 can be controlled by the control module 2. When the controller receives a change in the detection signal of the infrared sensing device 41, it controls the alarm 42 to sound an alarm to remind the on-site personnel. Infrared sensing device 41 is used to detect whether any person or object has entered the visual warning zone projected by laser emitting module 3. When no person or object or other external object enters the visual warning zone, the detection signal of infrared sensing device 41 can be a continuous low-frequency signal. When a person or object enters, infrared sensing device 41 generates a high-frequency signal, and vice versa. That is, when a person or object enters the visual warning zone, the detection signal of infrared sensing device 41 will change. After receiving the detection signal, control module 2 generates an alarm signal and controls alarm device 42 to sound an alarm. On-site personnel can immediately notice the alarm signal and take corresponding measures to ensure airport safety. At the same time, control module 2 will also send the alarm signal to the airport remote monitoring center through the communication module so that the airport remote monitoring center can understand the situation within the visual warning zone in real time and adjust or change airport operations based on the alarm signal.

[0042] In this embodiment of the application, the alarm 42 can be an LED light, a buzzer, or an alarm 42 formed by combining an LED light and a buzzer, etc.

[0043] Reference Figure 3The remote control module 6 includes a signal receiver 61 embedded in the lamp housing 1 and a wireless signal module 62 fixedly installed inside the lamp housing 1. The input end of the wireless signal module 62 is electrically connected to the output end of the signal receiver 61 to transmit the start or stop control commands sent by the field worker to the light fence via a mobile terminal to the wireless signal module 62. The output end of the wireless signal module 62 is electrically connected to the output end of the control module 2 to transmit the start or stop control commands to the wireless signal module 62. The input end of the wireless signal module 62 is electrically connected to the input end of the control module 2 to control the working status of the wireless signal module 62 through the control module 2. The field worker can establish a communication connection with the light fence through the signal receiver 61 using a mobile terminal or tablet computer, and thus control the opening or closing of the light fence through the mobile terminal or tablet computer. In this embodiment, the signal receiver 61 can be an antenna. The antenna receives the radio frequency signal emitted by the mobile terminal or tablet computer and transmits the received signal to the wireless signal module 62 through the radio frequency cable. The wireless signal module 62 identifies and decodes the received signal and then converts it into an electrical signal, so that the control module 2 can quickly identify the electrical signal to control the grating.

[0044] Reference Figure 3 An anti-tipping module 7 is fixedly installed inside the lamp housing 1 to monitor the state of the light barrier in real time and determine whether the light barrier has tipped over. The input terminal of the anti-tipping module 7 is electrically connected to the output terminal of the control module 2, so that the control module 2 can control the working state of the anti-tipping module 7. The output terminal of the anti-tipping module 7 is electrically connected to the input terminal of the control module 2, so as to transmit the monitoring signal of whether the light barrier has tipped over to the control module 2. In this embodiment, the anti-tipping module 7 can be a gravity anti-tipping switch, which uses gravity sensing to detect the tilt or tipping of the light barrier. When the light barrier tipps over under the impact of external force, the gravity anti-tipping switch triggers the generation of a power-off control signal, which is transmitted to the control module 2. The control module 2 disconnects the power supply to the laser emitting module 3 to prevent the laser emitting module 3 from still emitting light when the light barrier is tilted or tipped over, affecting pedestrians and aircraft and causing laser pollution. At the same time, the tilt power-off solves the potential circuit hazards and is safer.

[0045] Reference Figure 3The fault detection module 9 is fixedly installed inside the lamp housing 1 and connected between the power supply module 5 and the laser emitting module 3. The fault detection module 9 detects the current value of the laser emitting module 3 and sends the detected current value to the control module 2 in real time. After receiving the current value detected by the fault detection module 9, the control module 2 compares the current value with a preset current threshold. When the current value exceeds the preset current threshold, it indicates that the laser emitting module 3 is not working properly. The control module 2 generates a warning signal and drives the alarm 42 to sound an alarm to alert on-site personnel. Simultaneously, the control module 2 stores the fault information in the storage module for subsequent troubleshooting and analysis. Furthermore, the control module 2 also sends the fault information to the remote monitoring center via the communication module, allowing airport supervisors to promptly understand the fault situation, respond quickly, and perform repairs to ensure the normal operation of the light barrier. During the alarm process, the alarm 42 emits a clear audible and visual signal to attract the attention of on-site personnel, ensuring they can promptly detect and handle the fault.

[0046] Reference Figure 4 The lamp housing 1 has a mounting groove on its bottom plate sidewall. A flexible structure 8 is fixedly installed in the mounting groove. The flexible structure 8 includes a mounting block 82 and at least two flexible tabs 81. One side of each flexible tab 81 is fixedly connected to the sidewall of the mounting groove, and the other end is fixedly connected to the mounting block 82, thus securing the mounting block 82 in the mounting groove. The mounting block 82 has a through-hole 821, allowing for the fixed installation of the light barrier. When the light barrier is subjected to impact, the flexible tabs 81 are prone to breakage, causing the light barrier to tip over and preventing damage to the aircraft.

[0047] Reference Figure 1 A solar panel 12 is fixedly installed on the outer wall of the lamp housing 1. The output end of the solar panel 12 is electrically connected to the input end of the power module 5. When the solar panel 12 is exposed to sunlight, it generates electrical energy, which is stored in the power module 5. In this embodiment, the power module 5 is also provided with a charging interface, and a charging data cable is fixedly installed at the charging interface. The power module 5 is charged by plugging the charging data cable into the power source. At the same time, in order to ensure that the electrical energy connected to the solar panel 12 and the charging data cable is compatible with the power module 5, an electric drive module is also fixedly installed inside the lamp housing 1. The input end of the electric drive module is electrically connected to the output end of the solar panel 12 and the output end of the charging interface, and the output end of the electric drive module is electrically connected to the input end of the power module 5, so as to realize the conversion of electrical energy and ensure that the power module 5 can be charged and discharged.

[0048] The implementation principle of this application embodiment is as follows:

[0049] When a light barrier is needed for protection, pins, rivets, and other parts are used to fix the light barrier in place through the mounting holes 821. Then, all personnel entering the protected area of ​​the light barrier can send an activation command to the light barrier via a mobile terminal or laptop. After receiving the activation command, the signal receiver 61 transmits it to the wireless signal module 62. The wireless signal module 62 processes the activation command by performing data format conversion and other processing before sending it to the control module 2. The control module 2 activates the various modules inside the lamp housing 1 according to the activation command. The laser emitting module 3 emits a linear laser, which forms a visual warning zone in the air through the projection port 11. Simultaneously, the infrared sensing device 41 monitors the area within the visual warning zone, detecting in real time whether any person or object has entered the protected area. When a person or object enters the protected area, the infrared sensing device 41... When the output signal changes, the controller activates the alarm 42 to issue an alarm and sends the alarm signal to the airport remote control center via the communication module 10. Simultaneously, the fault detection module 9 monitors the current value of the laser emitting module 3 in real time and transmits the detected current value to the control module 2. The control module 2 compares the current value with a preset current threshold. When the current value exceeds the preset current threshold, a warning signal is generated, and the alarm 42 is activated to issue an alarm and send the warning signal to the airport remote control center via the communication module 10. The anti-tipping module 7 monitors in real time whether the light barrier is tilted or tipped over. When tilting or tipping is detected, a power-off control command is generated. Upon receiving the power-off control command, the control module 2 disconnects the power supply to the laser emitting module 3 to prevent the light barrier from continuing to project visual warning tape and affecting the aircraft even when tilted or tipped over.

[0050] During the use of the grating, when subjected to external impact, the easy-break piece 81 breaks, causing the grating to detach from the mounting block 82 and tilt at the installation position to avoid damage to the aircraft. At the same time as the grating tilts due to the impact, the anti-tilting module 7 detects that the grating is tilting, and at this time the control module 2 controls the disconnection of the power supply to the laser emitting module 3.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
