Description

Technical Field

[0001] The present application relates to the field of bridge pier safety warning, and in particular to a floating platform pontoon integrated bridge pier warning system and method. Background Art

[0002] With the development of water transport, the level of inland waterways has been improved. However, changes in restricted waters have led to changes in the navigation environment. Rivers and seas are directly connected, and ships are heading to the ocean. Traditional fixed pier warning devices have many shortcomings under water level changes and harsh environmental conditions.

[0003] Traditional fixed pier warning devices are usually fixed by driving piles underwater to fix their structures. They provide navigation information and warnings to ships mainly by means of lights and reflective strips. However, their fixed structure and reliance on photovoltaic power generation or external power sources make them vulnerable to damage under water level changes and harsh environmental conditions. They have high maintenance costs and insufficient power supply. In addition, the warning devices are fixed and difficult to move, and lack language to communicate with ships.

[0004] Patent CN114321808A has a possible similar scheme, including a guide rail, a navigation light and a float. The guide rail is extended along the height direction of the cliff. The float moves along the guide rail as the water level of the river rises and falls, and the navigation light is installed on the float. A mounting groove is provided on the float. The navigation light includes a lamp holder, a lamp body and a lampshade. The lamp holder is arranged in the mounting groove. A plurality of elastic members are evenly arranged circumferentially between the lamp holder and the inner side wall of the mounting groove. The lamp body is installed on the lamp holder. A shock-absorbing structure is provided between the lamp body and the lamp holder. A mounting cavity is provided in the lamp holder. A battery is provided in the mounting cavity. A solar panel is provided on the lamp holder. The solar panel is electrically connected to the battery, and the battery supplies power to the lamp body.

When the buoy 2 slides down to the lower end sensor 5, the control system determines that the water level is low at this time, and the control system sends a signal to the drive motor 15 to retract the anchor cable 6, so that the suspended platform body 1 drops to an appropriate position.

[0080] Four control rooms 17 are arranged in the main body of the suspended platform 1, and an anchor cable retracting and releasing mechanism is arranged in each control room 17.

[0085] A cross-shaped longitudinal rib plate 18 is arranged in the horizontal direction inside the main body 1 of the suspended platform, a ring plate 21 is arranged in the middle of the longitudinal rib plate 18, and a gravity pendulum power generation assembly is arranged inside the ring plate 21. Under the action of external forces such as wind, waves and currents, the swing of the gravity pendulum power generation assembly can consume part of the energy, thereby reducing the overall swing amplitude of the navigation mark, ensuring the stability of the navigation mark position, and providing accurate navigation information for ships.

[0086] A longitudinal rib plate 18 is provided inside the main body 1 of the suspended platform. A plurality of counterweight chambers 22 are provided between the longitudinal rib plate 18 and the inner side wall of the main body 1 of the suspended platform.

[0091] In one embodiment, the present application also provides a floating platform pontoon integrated bridge pier warning method, which is implemented by using the above-mentioned floating platform pontoon integrated bridge pier warning system. Figure 1 As shown, the floating platform pontoon integrated pier warning method includes:

[0092] Step 100: Acquire water level information data and target river channel information data. The information data includes: river channel information data and environmental information data; the river channel information data includes: image data and signal data; the environmental information data includes: visibility data and light data; the water level information data includes: water level amplitude.

[0093] Step 200: Perform ship recognition based on the image data to obtain a recognition result.

[0094] Step 300: If the identification result is that there is no vessel, the warning device is controlled to be turned off.

[0095] Step 400: If the identification result is that there is a ship, the visible distance of the ship is determined according to the signal data, and the warning device is controlled to be turned on or off according to the visible distance of the ship and the environmental information data.

[0096] Step 500: Determine whether to trigger the limit processing according to the water level information data.

[0097] If triggered, step 600 is executed: the motion state data of the floating platform body is determined according to the water level information data, and the anchor cable retracting mechanism is controlled to release or retract according to the motion state data.

[0098] In one embodiment, according to the visible distance of the ship and the environmental information data, controlling the turning on or off of the warning device specifically includes:

[0099] The visible distance of the ship is compared with a set value, and the driving state of the ship is determined according to the comparison result.

[0100] If the driving state is the departure state, the warning device is controlled to be turned off; if the driving state is the approaching state, the whistle is controlled to be turned on for sounding.

[0101] The on / off states of the fog lights and warning lights are controlled according to the environmental information data.

[0102] As an optional implementation method, controlling the on / off states of the fog lamp and the warning lamp according to the environmental information data specifically includes:

[0103] Determine whether the visibility data is within the set visibility range to obtain a first judgment result; if the first judgment result is no, control the fog lights to turn on; if the first judgment result is yes, control the fog lights to turn off, and determine whether the light data is within the set brightness range to obtain a second judgment result.

[0104] If the second judgment result is yes, the warning light is controlled to be turned off; if the second judgment result is no, the warning light is controlled to be turned on.

[0105] In one embodiment, judging whether to trigger the limit processing according to the water level information data specifically includes:

[0106] The water level information data is compared with the set water level value to obtain a comparison result; and whether to trigger the limit processing is determined according to the comparison result.

[0107] As an optional implementation, the motion state data of the suspended platform body is determined according to the water level information data, and the anchor cable retracting mechanism is controlled to release or retract according to the motion state data, specifically including:

[0108] If the water level information data is in a state of continuous rise, it is determined that the main body of the suspended platform is in an upward floating state. At this time, the anchor cable retracting and releasing mechanism is controlled to release.

[0109] If the water level information data is in a descending state, it is determined that the main body of the suspended platform is in a descending motion state. At this time, the anchor cable retracting and releasing mechanism is controlled to retract.

[0110] like Figure 2 As shown, in practical application, the technical concept of the present application can be as follows:

[0111] Step 1: Detect whether there are any ships passing through the target river channel through lidar, thermal imaging, image recognition, ultrasonic sensors, etc.

[0112] When the lidar, ultrasonic, and sensors detect that there is no ship passing, the system will automatically turn off the warning light and the whistle.

[0113] Step 2: When a ship passes by, use lidar, ultrasound, and sensors to detect whether the ship is approaching.

[0114] LiDAR, ultrasonic, and sensor detect whether a ship is approaching by emitting laser or ultrasonic signals and measuring the time and intensity of the signals reflected from the ship.

[0115] When the laser radar or ultrasonic sensor detects a short reflected signal with high intensity, reaching the set value, it is judged that the ship is approaching and has reached the visible distance of the ship. The set value can be adjusted according to the local terrain, climate, local standards and management departments.

[0116] When the laser radar or ultrasonic sensor detects that the reflected signal is long in duration and low in intensity, lower than the set value, it is judged that the ship is moving away, and the system will automatically turn off the warning light and the whistle.

[0117] The controller uses a control chip, such as a microcontroller unit MCU, which can be an STM32 series microcontroller, or an application-specific integrated circuit ASIC, for processing sensor data and sending control signals.

[0118] The controller makes corresponding judgments and control decisions based on the sensor data, that is, to make distance threshold judgments and signal strength analysis. For example, when the sensor detects that the reflected signal is short and strong, it determines that the ship is approaching and triggers the alarm and whistle mechanism.

[0119] When the controller determines that a ship is approaching, it sends a control signal to activate the whistle.

[0120] The whistle uses an electronic whistle device, which converts electrical signals into sound waves to produce whistle sounds.

[0121] Specifically, in actual applications, when it is determined that a ship is approaching, a controller such as a control chip sends a control signal through an I / O port to drive an electronic switch or relay of the whistle.

[0122] The control signal starts the whistle device through a driving circuit (such as MOSFET or relay driver), and the electronic whistle converts the electrical signal into sound waves to emit a set whistle sound.

[0123] Step 3: Use humidity sensors, air pressure sensors, visibility sensors and other devices to detect weather conditions and determine whether it is heavy rain, fog or other severe conditions.

[0124] When severe conditions exist, the control system determines whether to activate the fog light mode to turn on the fog lights based on the environmental condition detection results.

[0125] Step 4: When no adverse conditions exist, determine whether the light is dim.

[0126] When the light is dim, the warning light is turned on by detecting the current light condition through a photosensitive sensor (such as a photoresistor or a photodiode).

[0127] When the light is not dim (meets the standard), the warning light will go out regardless of whether there are ships passing by or not, and the warning sign will rely on its own reflection to provide warning.

[0128] Specifically, in practical applications, when an approaching ship is detected, the control of the warning light usually involves a series of electronic and mechanical systems.

[0129] The approach and distance of a vessel are detected using LiDAR and ultrasonic sensors. These sensors can accurately measure the distance between the vessel and the warning system and determine whether the warning lights need to be activated.

[0130] When the sensor detects that the ship is approaching and reaching the preset safety warning area, the control system will receive this signal.

[0131] The controller can be a microprocessor or programmable logic controller (PLC) based system that decides whether to activate the warning light based on the received signal and preset rules.

[0132] Once the control system decides to activate the warning light, it controls a relay or switch via an electrical signal, turning on the power to the warning light.

[0133] Warning lights usually consist of LEDs (light emitting diodes) or other high-brightness light sources to ensure that they can be clearly seen at night or in poor visibility conditions.

[0134] Use humidity sensors, air pressure sensors, visibility sensors, and more to detect weather conditions.

[0135] These sensors can measure parameters such as humidity, air pressure, visibility, etc. in the environment and transmit the data to the control system.

[0136] The controller determines whether the current environment is in severe conditions such as heavy rain or fog based on the received environmental data.

[0137] If adverse conditions are determined, the controller activates the fog lights or other appropriate warning devices.

[0138] Warning lights are lighting devices used on ships to send warning signals, usually used to mark dangerous areas, the edge of the channel or provide other important navigation information.

[0139] The color and flashing frequency of warning lights have specific meanings. For example, a red light usually means you need to turn right or watch out for hazards on the left, and a green light means you need to turn left or watch out for hazards on the right.

[0140] The warning light is provided by LED or other light sources. The control system controls the brightness of the LED by controlling the switch of the power supply or adjusting the current.

[0141] For warning lights that need to flash, the control system will control the flashing of the LED according to the preset flashing frequency and duration.

[0142] Fog lights are typically used to provide additional illumination and warning in low visibility conditions. When the controller detects adverse conditions such as heavy rain, fog, etc. through sensors, the fog lights will be activated.

[0143] The control method of fog lights is similar to that of warning lights, and the switch is also controlled by a controller.

[0144] Use a light-sensitive sensor (such as a photoresistor or photodiode) to detect the current light conditions.

[0145] The controller determines whether the light is dark based on the signal output by the photosensor. If the light is dark, the controller activates the warning light; if the light is not dark, the controller turns off the warning light.

[0146] The controller may contain a microprocessor chip, a PLC chip or other dedicated control chip to process sensor data, execute control algorithms and output control signals.

[0147] The control algorithm is a key part of the controller that decides how to control warning lights and other devices based on the sensor data it receives and the preset rules.

[0148] The control algorithm can be based on simple logical judgment, or it can adopt more complex algorithms such as fuzzy control, neural network, etc. to improve the intelligence and adaptability of the system.

[0149] In short, the control of ship warning lights involves many aspects, including sensor detection, control system judgment, electrical control, and environmental condition detection. Through reasonable system design and control algorithms, it can ensure that the warning lights can send warning signals in a timely and accurate manner when needed, thereby improving the safety of navigation.

[0150] like Figure 3 and Figure 5 As shown, in actual application, the control process of the anchor cable retracting and releasing mechanism can be as follows:

[0151] Step 1: Start detection by simultaneously using two ultrasonic sensors at the upper and lower ends of the sliding double columns to detect real-time data on current water level changes (depending on the height of the sliding double columns. If the height of the sliding double columns is 7 meters, the ultrasonic sensor will trigger the limit if the water level change exceeds 5 meters).

[0152] When the water level amplitude exceeds the specified value, it is considered that the water level amplitude has triggered the limit and enters the next step;

[0153] When the water level fluctuation does not exceed the specified value, it is considered that the water level fluctuation has not triggered the limit. At this time, there is no need to retract or release the anchor cable, and the buoy and warning equipment can automatically adjust by their own buoyancy and gravity.

[0154] Step 2: When it is considered that the water level fluctuation has reached the limit, the ultrasonic sensor starts detection.

[0155] When the ultrasonic sensor at the upper end of the sliding double columns detects that the water level continues to rise, it is judged that the warning buoy is floating up. At this time, the controller in the control room controls the motor to release the anchor cable.

[0156] When the ultrasonic sensor at the lower end of the sliding double column detects that the water level continues to drop, it is judged that the warning buoy is moving downward. At this time, the controller in the control room controls the motor to retract the anchor cable. At this point, the automatic retraction and release of the anchor cable is completed.

[0157] like Figure 4 As shown, photovoltaic panels (solar panels) absorb sunlight and convert it into electrical energy. Then, the electrical energy is stored in batteries to supply power when needed. The gravity pendulum and swing mechanism can consume part of the energy brought by external forces such as wind, waves and currents, thereby reducing the overall sway amplitude of the buoy and ensuring the stable operation of the system.

[0158] In addition to the main energy conversion and storage, the system also includes some auxiliary components, such as warning lights, sensors and control systems. The operation and energy consumption of these components are supported by the power provided by the battery. The warning lights are used to send warning signals when necessary, the sensors are responsible for collecting and transmitting various data, and the controller guides the operation of the entire system based on these data.

[0159] The system mentioned in this application can achieve autonomous power supply, that is, in the absence of an external power supply, the photovoltaic panels and batteries equipped by the vehicle can be used to provide power for various devices to ensure normal navigation and normal operation of various functions.
