Description

Technology Field

[0001] The present invention relates to an entry blocking device capable of controlling vehicle entry in the event of an accident on a vehicle transport route such as a road or tunnel, and more specifically, to a vehicle entry blocking device designed for easy installation and maintenance. It is a modular type designed with a structure in which a horizontal truss member is easily seated on a vertical member when combined with it, thereby reducing time and manpower during construction to reduce costs and ensure worker safety. Background Technology

[0002] Generally, tunnels and underpasses are constructed in response to the terrain to minimize driving distances, increase speed, and ensure smooth traffic flow. For example, underpasses are built underground to penetrate urban roadways from below, while tunnels are typically constructed to pass through mountainous terrain.

[0003] In particular, in the event of a fire accident caused by a traffic accident, vehicle fire, or electrical short circuit inside a tunnel, there is not only a high risk of suffocation from flames or smoke, but there is also a concern that large-scale human and material damage may occur if drivers enter the tunnel without realizing the accident in time, as prompt evacuation operations may not be carried out.

[0004] Therefore, although emergency means such as fire extinguishers are provided inside the tunnel, firefighting operations are impossible because the interior is dark and narrow, and it is very difficult for fire trucks to enter, so a device is being developed to block entry into the tunnel in case of emergency.

[0005] Furthermore, recently, there have been accidents in urban underpasses caused by drivers entering them without realizing that water has risen due to natural disasters such as floods, highlighting the need for measures to prevent accidents in tunnels and underpasses.

[0007] However, existing entry barriers installed in tunnels or underpasses consist of vertical and horizontal members on both sides, which necessitates the inconvenience of blocking both sides of the road for installation. Furthermore, the weight and size of the members require heavy equipment such as cranes, resulting in high construction costs and time. In particular, since assembly is only possible when the distance and horizontal alignment between the vertical and horizontal truss members are precise, any errors require not only significant time, manpower, and equipment but also rework. Prior art literature

[0008] - Republic of Korea Registered Patent No. 10-927571 - Republic of Korea Patent Application No. 10-2012-0062550 - Republic of Korea Patent Application No. 10-2023-0049373 The problem to be solved

[0009] The objective of the present invention is to solve the aforementioned problems by providing a vehicle entry barrier that enables simple installation and reduces construction time and manpower by utilizing a lightweight structure and modular components. In particular, the invention aims to provide an entry barrier with improved construction convenience, designed to allow for free adjustment after installation regardless of the distance between vertical members or horizontal conditions, thereby minimizing the role of a crane and enhancing construction safety. means of solving the problem

[0010] As a means to achieve the purpose of the present invention described above, the invention comprises a horizontal member configured in a modular form so as to be easily assembled on-site, a rail bracket made of a high-strength lightweight alloy that can be installed using only small lifting equipment, and a barrier housing including a barrier designed to be foldable so as to be easily unfolded along a rail and immediately usable after installation. The modular horizontal member is characterized by including a quick-lock system that facilitates the connection between vertical and horizontal members through a system that allows the horizontal member to be placed on a vertical member regardless of the truss length, move freely left and right to take position, and then be fixed, thereby enabling fixing using a fixing bracket without separate welding. Effects of the invention

[0011] According to the present invention, a vehicle entry blocking device can be installed in a short time with minimal manpower without the complex construction procedures of the past. In particular, since construction can be performed without separate large equipment even in urban areas or sites with limited space, costs and time can be drastically reduced.

[0012] In addition, the free-moving mounting system resolves the difficulties of horizontal alignment and distance measurement. By performing fastening operations only after complete mounting, the risk of pinching, punctures, and falls during construction is significantly reduced, thereby enhancing installer safety and simplifying maintenance, which effectively ensures stable road safety over the long term.

FIG. 5 is a block diagram illustrating the system of the present invention. FIG. 6 is a flood measurement system among the monitoring means according to the present invention. Specific details for implementing the invention

[0014] Hereinafter, a vehicle entry blocking device according to the present invention and a road blocking method using the same will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, redundant descriptions are omitted. Regarding each word in the specification such as tunnel, underpass, and soundproof underpass, the term "underpass" has been used as a representative term to encompass all three meanings, and it is understood that the same can be used in various situations and forms for warning and blocking vehicles.

[0015] In this invention, although fires resulting from automobile accidents are common in tunnels and flooding is common in underpasses, the description will be provided without special distinction as these types of accidents can occur equally in both underpasses and urban underpasses.

[0017] A vehicle entry blocking device (10) according to one embodiment of the present invention comprises a vertical member (100) installed at the entrance of a tunnel or underpass, a modular horizontal member (200) for coupling with the vertical member (100), a rail bracket supported by the modular horizontal member (200) and moving along a rail section, a blocking screen device (300) connected to the rail bracket to block vehicle entry, a housing (500) for storing the blocking screen device, a warning means (650) including an electronic display, a warning light, a speaker, etc., a monitoring means (600) such as a speed detection sensor, a CCTV, a radar sensor, a lidar sensor, a fire detection sensor, a water level sensor for flood detection, etc., and a control unit (700) for controlling all of the devices.

[0019] In particular, as shown in FIG. 4, the modular horizontal member (200) of the present invention has a structure in which metal structures (201, 202) for mounting the horizontal member are formed on both sides of the horizontal member (200) and are mounted on the top of the modular vertical member (100), and then the horizontal member (200) and the vertical member (100) are stably connected and fixed using a bracket (203) for fixing the horizontal member, and the modular horizontal member (200) is further stably connected by the bracket (203) for fixing the horizontal member by butting against one or more metal structures (102) for mounting the vertical member and one or more brackets (101) for the vertical member attached to the vertical member (100).

[0020] In addition, the metal structure (102) for mounting the vertical member, which supports the lower end of the horizontal member (200), can be configured to protrude a certain length to both the left and right sides of the vertical member (100), as shown in FIGS. 3 and 4.

[0021] Additionally, the metal structure (202) for mounting the horizontal member is a component that forms a modular horizontal member (200) and is composed of one or more cylindrical pipes or polygonal metals according to the weight and shape of the horizontal member (200), and the metal structure (102) for mounting the vertical member is also a component that forms a modular vertical member (200) with a thickness formed as a polygonal metal structure according to the weight and shape of the horizontal member (200).

[0022] The technical details above are specifically explained below in comparison with existing inventions.

[0023] First, in the case of the existing invention, in order to construct the vehicle entry blocking device (10), the dimensions between the vertical members (100) must be accurately measured, and the distance of the horizontal members (200), which are trusses, must be accurately cut and manufactured according to the measured distance. In order to combine the horizontal members (200) and the vertical members (100), the flanges installed on the horizontal and vertical members are fastened using bolts, etc. If an error occurs when cutting the horizontal members, assembly cannot be done and a new one must be manufactured. Also, if the horizontal members are not level, bolt assembly is impossible, and work must be done using a crane, etc. until the level is accurately aligned, which has problems regarding the safety of the workers (hand pinching, crushing, falling, etc.) and the need for a lot of time.

[0024] However, in the case of the present invention described above, it can be installed regardless of the length of the horizontal member when seated on the vertical member (100), and can be easily fastened by using a fixing bracket (203) to bolt together according to free movement left and right after seating on the vertical member (100), thereby having the advantage of solving the problems of the existing invention, such as the long time and safety issues of the worker.

[0025] In the present invention, all components of the existing invention are attached to the modularized vertical member (100) and horizontal member (200) or can be attached after construction, so all functions required for blocking vehicle entry operate identically. Therefore, when utilizing the vehicle entry blocking device (10) with improved construction convenience, the road blocking time during construction of the vehicle entry blocking device (10) is very short, and construction can be performed by blocking only one side of the road, or road blocking may be unnecessary.

[0026] In addition, in the present invention, a housing (500) for storing a blocking screen device (300) is installed on a vertical member (100) installed on both sides of the road, so that the blocking screen unfolds from both sides toward the center, but the housing (500) can be installed only on one side of the vertical member (100) to block only a part of the roadway.

[0027] As with the prior invention described above, the warning means (650) installed on the horizontal member (200) and the vertical member (100) includes a guide display board (guide display), a blocking screen device (300) that moves along a rail formed on the horizontal member (200), a variable signal light, a warning light, a speaker, a lighting light, etc., and a monitoring means (600) composed of a plurality of image measuring devices and data measuring sensors such as measurement sensors, so as to be able to measure the situation inside and outside the tunnel and underpass. The analysis unit compares and analyzes image data received from the image measuring device, which includes various cameras fixed on one side inside the tunnel and underpass to monitor real-time video and transmit information, with various data received from the monitoring means (600); a judgment unit that determines whether entry and exit to the tunnel and underpass is possible based on the data analyzed by the analysis unit and determines whether accident situations in the underpass can be predicted by learning big data patterns; and the blocking screen device (300) according to the control of the control device as a result of the judgment of the judgment unit. Vehicle entry can be blocked by operating a warning means (650) including the warning means.

[0028] In particular, among the monitoring means (600), the water level measuring sensor for measuring the water level in the event of flooding may be equipped with a Doppler radar, a water level difference sensor, and an ultrasonic sensor for measuring the water level and flow velocity to check the amount of water flowing into the underpass (especially the underpass) in real time, and may capture the amount and speed of water flowing into the underpass in real time using a camera and record the process of change of the captured image.

[0029] In addition, the control unit (not shown) of the present invention is configured to operate through an auto mode (automatically instructed by the control center) and a manual mode (manual operation according to the field situation), and is responsible for the control of all various warning means (650) separately equipped together with the vehicle entry blocking device (10). The warning means (650) includes safety lighting equipment and warning devices installed inside and outside the tunnel or underpass, and detects sudden situations inside the tunnel or underpass using water level sensors for flood detection, speed sensors, and cameras including CCTV installed in sections within the underpass, thereby generating a sudden situation detection signal. It analyzes the section-specific measurement data received from the sensors and cameras to determine the priority of the sudden situation, and generates a danger signal or warning signal according to the priority, thereby enabling the driver to recognize the danger signal or warning signal using sight and hearing through the integrated control server, evacuation guidance information including the evacuation direction for each section. When a danger signal is received from the integrated control server (400), an entry blocking device for blocking vehicle entry into the underpass It is designed to operate and, in the event of an emergency, effectively provide not only a blocking function but also a warning function. The vehicle entry blocking device installed at the entrance of the underpass is installed on the upper part of the horizontal member (200) and serves as a warning means (650) to indicate the prohibition of entry of vehicles entering in the event of a disaster risk. In addition to visually blocking entry using warning text on the blocking screen device (300), the warning means (650) is designed to be identifiable even from a distance under strong sunlight by using the red, yellow, and blue colors of LEDs. Depending on normal traffic conditions, cases where vehicles inside the underpass are blocked and caution is required, and cases where entry is impossible due to fire or traffic accidents, the driver can easily recognize it from a distance. Furthermore, the dangerous situation can be indicated by sound using a warning sound, and various other methods are used to ensure that there is no situation where the driver fails to recognize it.

[0030] The above warning means (650) includes at least one of a surface light, a warning light, an underpass name display, a visual guidance light, and a speaker installed in the entry blocking device, and a fire extinguisher indicator light, a gobo light, a pictogram display, a speaker, and an electronic display installed inside the underpass, and is capable of emitting a preset color or displaying evacuation guidance information and generating a warning sound according to a danger signal or warning signal received from the integrated control server (400).

[0031] In addition, in the present invention, the underground road is monitored by various monitoring means (600), such as sensors and cameras installed in each section of a pre-divided tunnel or underground road, through which measurement data of each section of the underground road and speed data detecting the speed of a vehicle traveling in the underground road are detected, and a fire detection signal is generated when a fire occurs in the underground road and a water level detection sensor is detected when flooding occurs. Then, the monitoring means (600) detects an unexpected situation through the video data and speed data of each section of the underground road, the fire detection signal, and the water level signal, generates an unexpected situation detection signal, and transmits the video data and the unexpected situation detection signal to an integrated control server (400). When the integrated control server (400) recognizes one or more unexpected situations among fire, flooding, traffic accident, traffic congestion, falling objects, and slow vehicles according to each section using the video data and unexpected situation detection signal of each section of the underground road, the integrated control server (400) [recognizes] the unexpected situation recognized for each section of the underground road according to a pre-set Based on the criteria for determining the priority of sudden situations, the priority among the sudden situations in each section is determined, and the sudden situation with a high priority is extracted. The integrated control server (400) generates a red color as a danger signal when the sudden situation with a high priority is a fire, flood, traffic accident, etc., and generates a yellow signal when the sudden situation with a high priority is a traffic congestion, falling object, or slow vehicle, and transmits this to the warning means (650) installed in each section of the underpass and the vehicle entry blocking device (10) located at the entrance of the underpass. The warning means (650) emits a preset color according to the danger signal or various warning signals received from the integrated control server (400).When the vehicle entry blocking device receives the danger signal, the blocking screen device (300) is linked to automatically unfold, and the integrated control server (400) extracts the section where a high-priority sudden situation has occurred using pre-stored section-by-section location information of the underpass. Then, the integrated control server (400) extracts the evacuation direction according to the extracted section-by-section location of the underpass entrance, underpass exit, or emergency exit, and the driver is able to recognize the evacuation guidance information including the evacuation direction through the corresponding warning means (650) to enable evacuation. Furthermore, the integrated control server (400) recognizes the lanes through video data of the section between the underpass entrance and the section-by-section to calculate the number of vehicles in each lane, and the integrated control server (400) compares the calculated number of vehicles in each lane and utilizes the lane with the minimum number of vehicles as an entry route for emergency vehicles, etc., which occur within the underpass In addition to enabling integrated control of warning means such as underpass lighting and vehicle entry blocking means according to sudden situations, the reliability of warnings regarding sudden situations is improved to prevent driver confusion and to allow the driver to easily and quickly recognize the sudden situation, thereby enabling an early response to the sudden situation and preventing secondary accidents. The above-mentioned integrated control server (400) can transmit and receive all of the above information so that it can be recognized and instructed on the manager's mobile phone or the manager's monitor.

[0032] The above monitoring means (600) is installed in each section partitioned along the longitudinal direction of the underpass to monitor the interior of the underpass, and it is preferable to use a speed detection sensor, CCTV, radar sensor, lidar sensor, fire detection sensor, water level sensor for flood detection, or an incident detection system. At this time, the monitoring means (600) must store identification information including the installed location so that it can be identified from other monitoring means installed in each section.

[0033] In particular, for sensors capable of detecting water levels in the event of flooding in or inside an underpass, non-contact methods may utilize radar, ultrasound, light, or video such as CCTV, or contact-type floats or capacitive sensing sensors may be used individually or simultaneously.

[0034] In addition, for accurate system operation, stability can be ensured by operating the system when contact and non-contact sensors operate simultaneously or when at least two or more sensors operate.

[0035] FIG. 6 illustrates the water level measurement and measurement method of an underpass (underpass) flood measurement system according to one embodiment of the present invention.

[0036] Looking at the sequence of the measurement system, it may include a step of measuring the real-time video of the video measuring device above the underpass and the flow velocity and water level of the incoming water, a step of transmitting the measured real-time video and data to a control unit for analysis to determine whether flooding has occurred within the underpass, and a step of transmitting to a plurality of situation guidance (warning) devices, entry blocking devices, and an integrated control server (400) located outside the underpass via a communication device in the event of flooding to execute.

[0037] As shown in FIG. 6, the measurement of whether flooding has occurred was performed using an inspection processor that lights up a normal lamp when water level sensors 1, 2, and 3 each operate, a processor that determines the operation of a barrier outside the underpass as flood stage 1 when sensors 1 and 3 operate, either manually or under the control of a control server (400), and two self-standing float water level sensors and one ultrasonic sensor that immediately operate the barrier outside as flood stage 2 when sensors 1, 2, and 3 operate. A protective cover was installed to protect the measurement sensors and to prevent contamination and damage.

[0038] The two above-described self-standing float level sensors are designed so that as the liquid level rises, the float receives buoyancy and rises along with the liquid level, causing the proximity switch (Reed Switch) located inside the guide pipe at the control position to reach a fixed position. The contacts of the Reed Switch are switched on and off by the magnet inside the float, allowing for accurate detection of the boundary surface of the measured object. Each sensor is installed at a different location to prevent errors during measurement, and an ultrasonic sensor is additionally installed to enhance reliability.

[0039] In addition, the step of measuring the real-time video and the flow velocity and water level of the incoming water may further include the step of collecting the image change process by having the image measuring device installed in the underpass capture the amount and speed of the water flowing into the underpass in real time, and the step of measuring and collecting the flow velocity and water level of the water flowing into the underpass as waves by installing a Doppler radar in addition to the measurement sensor installed in the underpass to ensure reliability and minimize the influence of environmental changes.

[0040] Additionally, the step of determining whether flooding has occurred by the control unit (not shown) may include the step of collecting data measured in the underpass in the control unit, the step of receiving weather and heavy rainfall location data and data measured in a control unit in another region from the control server (400) and collecting them in the control unit, the step of equipping the control unit with a deep learning system or artificial intelligence (AI) to select flooding occurrence patterns and frequent flooding locations using the data collected in the control unit, and the step of notifying the integrated control server (400) via the communication device of the area where flooding is predicted to occur through the deep learning system in the control unit.

[0042] In addition, the vehicle entry blocking device with improved construction convenience according to the present invention can be similarly constructed or installed on a unidirectional vehicle entry blocking device having a vertical member (100) and a horizontal member (200) on one side rather than both sides, in cases where the road conditions or the road width is narrow.

[0044] The above-described unidirectional vehicle entry blocking device includes the same functions and auxiliary equipment as the general vehicle entry blocking device described above, which has vertical members (100) on both sides. However, depending on the characteristics of the unidirectional type, a separate hook can be installed on the upper part of the horizontal member (200) to prevent safety and sagging by using the vertical member (100) and one or more support lines (201). Since the unidirectional type often has entrances and exits simultaneously based on the central divider line depending on the underground road or the road of the underground road, it can be mainly used when an entry blocking device is to be installed only on the entrance side.

[0046] In addition, since corrosion of all metal structures used in the present invention, and especially the spring (221) used in the present invention, can cause problems when folding and unfolding the barrier due to changes in the elasticity of the spring caused by corrosion occurring in the metal material over time, the invention aims to maximize the lifespan by coating with a nano-inorganic material to ensure sufficient resistance to rust and corrosion.

[0048] FIG. 5 is a control circuit block diagram of the vehicle entry blocking device of the present invention. Referring to FIG. 5, a control unit (not shown) for driving the vehicle entry blocking device (10) of the present invention comprises: a user operation unit provided to support user operation related to the operation of warning means (650) and monitoring means (600), such as the aforementioned electronic display board, blocking screen device (300), and lighting; a power supply unit connected to each part to convert AC power supplied from the outside into DC power and supply necessary power, for example, 5[V] to 12[V], to the entire vehicle entry blocking device; an illuminance sensor that senses the current external illuminance; a comparison unit that compares a value set by the user operation unit with a value transmitted from the illuminance sensor and outputs a high-level (H) or low-level (L) logic value; a control signal that generates a corresponding control signal in response to the operation signal of the user operation unit, outputs a lighting control signal by combining the logic value transmitted from the comparison unit with an accident occurrence signal input according to the occurrence of an accident, and outputs an LED control signal for controlling the LED of the electronic display board in response to the accident occurrence signal. It is composed of a microprocessor that outputs a motor control signal for moving a blocking screen device (300) in response to an accident occurrence signal, an inverter circuit that generates and supplies AC power to light up a lighting light in response to the lighting control signal, a matrix driving circuit that generates a driving signal for driving each LED arranged in a matrix form in response to the LED control signal, a motor driving circuit that rotates a motor in forward / reverse direction in response to the motor control signal, and a memory that stores a program and driving data related to the matrix driving.

[0050] In addition, as an embodiment of the present invention regarding flooding inside an underpass, the water level measuring system among the monitoring means (600) comprises a plurality of situation guidance (warning) devices installed outside the underpass, an image measuring device fixed to the upper part inside the underpass to transmit real-time video of the underpass, a water level measuring sensor installed at the lower part inside the underpass to measure the flow velocity and water level of the flooded area, and can store and transmit information obtained from the image measuring device and the water level measuring sensor through the control of the control unit.

[0051] In addition, the control unit responsible for all control of the present invention is responsible for all control of various warning devices (650) separately equipped together with the vehicle entry blocking device, and the multiple warning devices (650) include safety lighting equipment including electronic display boards and warning devices installed inside and outside the underpass. Inside the underpass, among the monitoring means (600) installed by section, the control unit detects sudden situations inside the underpass from a water level measuring sensor for flood detection, a flow velocity sensor, and a video measuring device including a CCTV, and generates a sudden situation detection signal. It analyzes the measurement data received by section from the sensors and cameras to determine the priority of the sudden situation, and enables the driver to recognize a danger signal or a warning signal using sight and hearing according to the priority. By automatically blocking the entry of a vehicle immediately according to the priority or receiving a danger signal from the integrated control server (400) and operating an entry blocking device to block the entry of a vehicle, the control unit effectively adds a warning function as well as a blocking function in the event of an emergency.

[0052] In addition, the above control unit may include a device that analyzes and judges acquired information and communicates, and in order to prepare for the paralysis of the electrical / communication system in emergency situations such as fire or flooding and to configure multiple communication means, it establishes a wired / wireless communication network by configuring RF wireless communication using Zigbee, LoRa, etc. and incorporates an emergency power source so that an emergency control signal can be sent even if the main power is cut off.

[0053] Here, the analysis unit analyzes the camera's image and flow velocity and water level measurement data, stores the data, and can share information with the integrated control server (400) through a communication device.

[0054] The above judgment unit determines whether entry to the underpass is possible using data analyzed by the above analysis unit, and not only can it control multiple warning devices (650) and entry blocking devices located outside the underpass through a communication device, but also shares weather, flood, and various data with underpass entry blocking devices provided in other regions, judges the shared big data, and predicts flooding conditions to ensure reliability in controlling the underpass entry blocking devices.

[0055] The above communication device can utilize an intelligent system that can determine various accident situations, including flooding in an underpass, in a judgment unit and transmit them to an integrated control server (400) connected to the outside, and can communicate directly with national agencies such as the intelligent national disaster safety facility integrated management system or 112 (police station), 119 (fire station), etc., or communicate through the integrated control system (400).

[0056] The integrated control server (400) stores underground tunnel and underground tunnel status data including location information and status information for each underground tunnel or underground tunnel, and the stored status data is connected to the national disaster safety facility portal management system so that it can be viewed or communicated at any time in the national integrated portal management system in response to natural disasters, thereby enabling management in the national integrated portal management system at the time when a natural disaster is expected, and in the event of an accident, it can be immediately connected to relevant ministries, police stations, fire stations, etc., to enable emergency measures.

[0058] In addition, as the vehicle entry barrier may experience operational problems due to corrosion on all metal materials used over time, we aimed to maximize the durability of the device by coating it with nano-inorganic materials to ensure sufficient resistance to rust and corrosion.

[0059] The above-mentioned nano-inorganic coating can be used to prevent rust and corrosion of all metals used in the blocking device of the present invention, and the nano-inorganic material is,

[0060] It comprises at least one of sodium oxide (Na2O), potassium oxide (K2O), and lithium oxide (Li2O), which are alkali metal oxides (M2O) represented by the following chemical formulas; an inorganic acid compound; and water (H2O);
