Description

Technical Field

[0001] The utility model belongs to the technical field of wireless communication obstacle detection, and in particular relates to a split obstacle detection device used for non-stop flight construction at an airport. Background Art

[0002] During the operation, construction, and expansion of the airport, night operations often occur. In some of the airport's internal activity areas, there are many operating units, many operating points, and relatively scattered personnel during the operation. During night operations, inappropriate area markers are placed in the activity and non-activity areas, and vehicles and machinery frequently shuttle between runways, taxiways, and connecting roads. The nighttime airport lights cause certain interference to drivers, which can easily cause unclear vision during driving. Only low beam lights can be used when driving in the airport. The reflected light from items such as reflective vests and reflective stickers is too close, and obstacles can only be seen clearly when the vehicle is very close. There are safety hazards when vehicles are driving at night.

[0003] Due to the particularity of non-stop construction at the airport, in order to ensure the safety of vehicles and personnel, temporary structures such as inappropriate area markers, and prevent collisions during night driving, a safe and reliable obstacle detection device is urgently needed. Utility Model Content

[0004] The utility model aims to solve the problem of nighttime construction at an airport without stopping flights and provides a split obstacle detection device for the construction at an airport without stopping flights.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A split obstacle detection device for non-stop construction at an airport comprises a transmitter and a receiver arranged in a control area for construction operations; wherein the transmitter is provided with a Bluetooth module I; the receiver is provided with a Bluetooth module II and an alarm module II; the Bluetooth module I is wirelessly connected to the Bluetooth module II; there are a plurality of receivers, which are respectively installed on objects (obstacles and unsuitable area signs, etc.) in the control area and on personnel entering the control area for operations; the alarm module II of the receiver installed on the object in the control area is composed of a four-sided light source capable of controlling each side of the light source individually and a buzzer; the alarm module II of the receiver installed on the personnel entering the control area for operations is composed of a low-frequency flashing light source and a buzzer.

[0007] In the present invention, the transmitter is installed on the vehicle entering the control area. It detects the receiver within a certain range and establishes a connection through Bluetooth communication. After the receiver establishes a connection with the transmitter, the alarm module II of the receiver can emit a light signal as an alarm signal to remind the driver of the vehicle to avoid it. The Bluetooth communication method is a communication method that is close-range networking and does not go through an outsourced network. It can eliminate the risk of information leakage and meet the requirements of communication security in the airport area. At the same time, according to the characteristics of the location where the receiver is installed, the present invention uses different types of alarm modules II. In view of the specific requirements of the airport for lighting, the alarm module II of the receiver installed on the object uses a four-sided light source module that can control each light source individually. After the alarm module II is fixedly installed, the light-emitting surface facing the aircraft side or the special scene side is controlled not to emit light. That is, the receiver placed at obstacles or inappropriate area markers has four-sided light sources. If it is placed at the junction of the closed area and the open area, the side facing the open area is set not to emit light. If it is placed at the turning point of the paddock road, the collapsed place, etc., it can be set to emit light on all four sides. The specific use of the light can be controlled according to the actual situation on site. The light state of the light source can be controlled by the MCU or by external buttons.

[0008] As a further description of the present invention, the receiver also includes a power supply II, a power management module and an MCU II; the MCU II is connected to the power supply II through the power management module; the Bluetooth module II and the alarm module II are respectively connected to the MCU II.

[0009] MCUⅡ is connected to power supply Ⅱ through power management module, which can realize efficient use of electric energy. When the receiver is not connected to the transmitter, it is in power saving mode and alarm module Ⅱ does not work. When the connection is established, MCUⅡ issues instructions to provide working power for alarm module Ⅱ and send out corresponding optical signals.

[0010] As a further description of the present invention, the power source II is a rechargeable power source.

[0011] As a further description of the present utility model, the transmitter also includes a power supply I, an MCU I, an AD conversion module, a speed sensor, a display and an alarm module I; the power supply I, the Bluetooth module I, the AD conversion module, the display and the alarm module I are respectively connected to the MCU I; the AD conversion module is also connected to the speed sensor.

[0012] The display is used to display the number and distribution of receivers detected by the transmitter, the distance between the transmitter and the receiver, the receiver number, the receiver power and status information, the current speed information of the vehicle where the transmitter is located, warning information, etc.

[0013] The warning module I is used to send a warning signal to the vehicle driver.

[0014] Speed ​​sensor, used to measure the current moving speed of the transmitter.

[0015] After Bluetooth module I and Bluetooth module II establish connection, the distance between the transmitter and the receiver can be measured.

[0016] As a further illustration of the present invention, the alarm module I uses a volume-controllable buzzer. The volume and frequency of the alarm module I are controlled by MCU I according to the distance between the transmitter and the receiver. The closer the distance between the transmitter and the receiver, the louder and more urgent the alarm sound emitted by the alarm module I.

[0017] The working principle of this utility model:

[0018] The transmitter is installed in the vehicle entering the control area. The transmitter continuously scans the receivers within the range through the Bluetooth module I. When the receiver is scanned within the range, a connection is established. The transmitter can establish connections with multiple receivers. When the upper limit of the connection is reached, the Bluetooth module I continues to scan the remaining receivers within the range, and reflects the IDs of the connected and scanned but unconnected receivers to MCU I. MCU I timely counts and records, and finally reflects the number of receivers scanned by the Bluetooth module I in real time, the distance between the transmitter and the receiver, the receiver ID, the receiver power, the status and other information on the display. Since there is an upper limit on the number of receivers connected to the transmitter, and each receiver can only be connected to one transmitter at a time, in order to ensure that the transmitter does not excessively occupy the receiver resources, when the transmitter and the receiver are connected, MCU I starts timing. If there is no distance change between the transmitter and the receiver within 10 seconds or a custom time, the Bluetooth is disconnected to ensure that the receiver can be discovered and connected by other transmitters. The transmitter will record the ID of the receiver that is automatically disconnected due to timeout in the database. After the transmitter's Bluetooth module I is connected to other receivers, the ID of the last receiver that was disconnected due to timeout will be reset in the database. At this time, the transmitter can establish a connection with this receiver through Bluetooth module I (Explanation: There are two situations at this time. Situation 1: The transmitter is in the state where the number of connected devices has reached the upper limit. After one of the receivers is disconnected, there are other receivers around. In this case, the transmitter connects to other receivers and the ID of the last receiver that was disconnected due to timeout is reset; Situation 2: The transmitter is in the state where the number of connected devices has reached the upper limit, but there are no other receivers around or the transmitter is not at the upper limit of the number of connected devices. In this case, the transmitter will not reset the ID of the last receiver that was disconnected due to timeout until it connects to the next receiver. In both cases, a new receiver needs to be connected to reset the ID of the last receiver that was disconnected due to timeout). The connected Bluetooth can be automatically disconnected after exceeding the Bluetooth connection range and enter the search state waiting for connection again.

[0019] After the receiver enters the scanning range of the transmitter, the Bluetooth module II of the receiver establishes a connection with the Bluetooth module I of the transmitter. At the same time, the MCU II of the receiver controls the alarm module II to emit sound and light signals to remind the vehicle driver.

[0020] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0021] 1. As the construction work at the airport is often carried out at night without stopping flights, the lighting in the airport runway, taxiway and other areas is dim, and the vehicle driving regulations do not allow the use of high beam lights. The utility model directly connects the transmitter with the receiver to remind the drivers, construction workers, obstacles and other safety information in the field; it improves the life safety of the construction workers and drivers in the field, and installs the receiver on the markers in the unsuitable areas at night to prevent the vehicle from colliding with objects, reducing the hidden danger of FOD in the open areas of the airport such as the runway and taxiway.

[0022] 2. The detection device of the utility model has a simple structure, low manufacturing cost, and direct end-to-end communication without going through the Internet, so the data security is better.

[0023] 3. The monitoring data of the utility model is convenient for monitoring each receiving end, and can also provide timely reminders for replacement when the power is insufficient or the equipment fails, thereby ensuring the normal operation of the equipment.

[0024] 4. The detection device of the utility model can be used not only for the construction of airports without stopping flights at night, but also for highway construction, house construction and other works with a lot of night construction and a certain confidentiality.

[0028] The utility model is further described below in conjunction with the accompanying drawings. Example

[0029] A split obstacle detection device for non-stop construction at an airport comprises a transmitter and a receiver arranged in a control area for construction operations; wherein the transmitter is provided with a Bluetooth module I; the receiver is provided with a Bluetooth module II and an alarm module II; the Bluetooth module I is wirelessly connected to the Bluetooth module II; there are a plurality of receivers, which are respectively installed on objects (obstacles and unsuitable area signs, etc.) in the control area and on personnel entering the control area for operations; the alarm module II of the receiver installed on the object in the control area is composed of a four-sided light source capable of controlling each side of the light source individually and a buzzer; the alarm module II of the receiver installed on the personnel entering the control area for operations is composed of a low-frequency flashing light source and a buzzer.

[0030] As further illustrated in this embodiment, Figure 2 As shown, the receiver also includes a power supply II, a power management module and an MCU II; the MCU II is connected to the power supply II through the power management module; the Bluetooth module II and the alarm module II are respectively connected to the MCU II.

[0031] Further description: the power supply II is a rechargeable power supply.

[0032] As further illustrated in this embodiment, Figure 1 As shown, the transmitter also includes a power supply I, MCU I, an AD conversion module, a speed sensor, a display and an alarm module I; the power supply I, Bluetooth module I, AD conversion module, display, and alarm module I are respectively connected to MCU I; the AD conversion module is also connected to the speed sensor.

[0033] To further explain, the alarm module I uses a buzzer with controllable volume.

[0034] In actual use, the transmitter is installed on the vehicle entering the control area. During the movement of the vehicle, the speed sensor displays the speed information on the display after being processed by MCUⅠ. The transmitter continuously traverses the receivers within the range through Bluetooth moduleⅠ. When the receiver is searched within the Bluetooth range, it establishes a connection with the receiver. At this time, the transmitter: the display will display the distance information, speed information, connected receiver ID, number of receivers within the transmitter range, and receiver power information, accompanied by a sound warning. The receiver's alarm moduleⅡ is activated after the Bluetooth connection, and the light source automatically lights up. The warning module II of the receiver installed at obstacles such as markers in the unsuitable area is an acoustic and light warning module, in which the light source is a four-sided controllable light source, and the four sides have independent external switches. The four-sided controllable light source can be set to be controlled by the MCU or by an external switch according to actual needs. For example, to prevent the light from interfering with the aircraft, the light of the aircraft facing the open area can be turned off during non-stop construction; the warning module II of the receiver worn by the construction personnel is an acoustic and light warning module, and the light source is a low-power stroboscopic light source. The battery is connected to the power management module to increase the service life. The sound of the acoustic and light warning module changes with the distance between the transmitter and the receiver.

[0035] There are two ways to disconnect Bluetooth (such as Figure 3 As shown in the figure): One is natural disconnection. When the distance between the transmitter and the receiver exceeds the signal transmission distance, the Bluetooth connection is automatically disconnected and prepares for the next connection. In this form of disconnection, the receiver ID will not be recorded, and the next time it can be directly connected within the Bluetooth connection range; the other is when the MCU determines that the distance between the transmitter and the receiver has not changed within the specified time, the Bluetooth is automatically disconnected and prepares for the next connection to improve the connection efficiency. At the same time, in this case, it is assumed that the transmitter has observed the existence of the receiver. The transmitter records the receiver ID and will not connect to it for a short time until the transmitter is connected to another group of receivers and the default ID library in the transmitter is reset. Only then can the transmitter connect to the receiver.

[0036] Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation of the present invention. For ordinary technicians in the relevant technical field, other different forms of changes or modifications can be made based on the above description; it is not necessary and impossible to list all the implementation methods here; and the obvious changes or modifications derived from them are still within the scope of protection of the present invention.
