Description

[0002] As the combination part of railway and road traffic, the management safety of railway crossings is related to the safety of traffic pedestrians and also needs to take into account the operation safety of railway locomotives.

[0003] The existing protection method for railway crossings adopts vehicle identification, pole dropping, and alarm. After manually identifying that the vehicle has passed, the crossing staff remotely control or manually raise the pole to release the passing vehicles and pedestrians. This method requires arranging a large number of protection personnel to manually determine whether the vehicle has passed, consuming human resources and having low efficiency.

[0004] To solve the above technical problems, those skilled in the art have proposed an automatic crossing protection method, where the vehicle approaching automatically alarms and drops the pole, and after the vehicle has completely passed, the pole is automatically lifted to release the vehicle and pedestrians. Therefore, there is no need to deploy full-time personnel for each crossing to ensure the safety of pedestrians and vehicles. However, although this automated system can effectively prevent vehicle passage, there is a problem of insufficient protection for pedestrians. Due to the lack of manual monitoring, some pedestrians may climb over the railing or crawl under the railing, and children are also likely to bypass the railing, making the protection effect for pedestrians unsatisfactory.

[0028] The following will describe the embodiments of the present invention in detail with reference to the drawings. It should be clear that the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] AsFigure 1-8 As shown, in some illustrative embodiments, a railway crossing protection device is provided, including: a locomotive detection device 1, an electric barrier machine 2, an outdoor crossing cabinet 3, a control host 4, a crossing signal machine 5, a laser sensor 6, and a monitoring camera 7.

[0030] The locomotive detection device 1 includes: a magnetoelectric inductor 101 and a proximity controller, which are used to collect locomotive running position and locomotive running direction data. The magnetoelectric inductor 101 can adopt an existing passive inductor that can realize train axle counting and vehicle number identification, and is installed on the railway rail 8 using a special installation bracket. Different railway rails use different installation card seats. Since the on-site vehicle speed is relatively low, the adopted sensor must be able to identify vehicle speeds of 0 - 120 KM.

[0031] The distance L between the magnetoelectric inductor 101 and the railway crossing is L = VT, where V is the average train speed and T is the approach time. Generally, the value of T should be 45 seconds or more.

[0032] The magnetoelectric inductor 101 is connected to the data signal input terminal of the proximity controller. Specifically, the data signal input terminal of the proximity controller includes an IN - port and an IN + port. The IN - port is connected to the signal negative terminal of the magnetoelectric inductor 101, and the IN + port is connected to the signal positive terminal of the magnetoelectric inductor 101. The magnetoelectric inductor 101 sends the data it collects to the proximity controller, and the proximity controller is used to obtain the data of the magnetoelectric inductor and send corresponding electronic instructions to the control host 4 based on the locomotive running position signal and the locomotive running direction signal, thereby uploading the locomotive position information and the traveling direction to the control system.

[0033] The electric barrier machine 2 is set at the level crossing of the railway and the road, and is used to receive the control instruction sent by the control host 4 and perform the corresponding actions of lifting and lowering the pole. When the pole is lifted, it allows passage, and when the pole is lowered, it closes the road. Specifically, the electric barrier machine 2 includes: a drive machine 201 and a railing connected to the drive machine 201.

[0034] The drive machine 201 is used to provide power for the lifting and lowering of the railing. The drive machine 201 includes: a chassis, a movement mechanism, and a control system; the movement mechanism is composed of a drive motor, a speed change mechanism, and a crank - connecting rod mechanism, and the power of the drive motor is 500W; the control system is composed of a control main board and a remote controller.

[0035] The railing is composed of two arm rods 202 and a number of blocking members 203 arranged on the arm rods 202.

[0036] A reinforcing cross - beam 204 is arranged between the two arm rods 202, and the two arm rods 202 gradually approach and are connected at the rod ends, forming an A - shaped structure with the reinforcing cross - beam 204, which can effectively disperse and bear the wind force, reduce the influence of the wind on the structure, and thus improve the wind resistance of the structure.

[0037] The boom 202 is made of aluminum alloy and has a black and white reflective film on its surface, which can prompt pedestrians and passing vehicles at night.

[0038] The length of the boom 202 is 10 meters.

[0039] A connection slot 2021 is opened at the bottom of the boom 202. The connection slot 2021 is used to accommodate the blocking member 203. When the electric barrier 2 receives a raising instruction, the drive machine 201 starts and drives the boom 202 to rotate around the bottom axis. When the boom 202 is lifted to be perpendicular to the ground, the blocking member 203 is completely located within the connection slot 2021. At this time, the railing is in the raised state, allowing vehicles and pedestrians to pass. When the electric barrier 2 receives a lowering instruction, the drive machine 201 drives the boom 202 to rotate in the reverse direction, and the boom 202 gradually flattens. During the process of the boom 202 falling, the blocking member 203 rotates out of the connection slot 2021 due to its own gravity until the boom 202 is parallel to the ground. When the boom 202 is parallel to the ground, the blocking member 203 is perpendicular to the ground, closing the space below the railing to complete the blocking action.

[0040] The blocking member 203 can effectively cover the space below the boom 202, forming a continuous blocking surface to prevent anyone from passing through from below, thereby effectively preventing pedestrians and children from attempting to crawl or bend down to pass through the railing. Moreover, when the boom 202 is lowered, the blocking member 203 automatically swings out to quickly close the space below the boom 202. When the boom 202 is lifted, the blocking member 203 automatically retracts into the connection slot 2021, reducing the space occupied by the railing in the raised state.

[0041] The blocking member 203 includes: a support rod 2031 and a U-shaped frame 2032. The support rod 2031 is arranged on the arc part of the U-shaped frame 2032. The open end of the U-shaped frame 2032 is hinged within the connection slot 2021, enabling the blocking member 203 to swing on the boom 202. The design of the U-shaped frame 2032 is used to accommodate the support rod 2031 of the blocking member adjacent to this end. That is, when all the blocking members 203 are fully retracted into the connection slot 2021, the support rod 2031 of this end will be embedded in the U-shaped frame 2032 of the blocking member adjacent to this end, enabling the blocking member 203 to occupy the least space within the connection slot 2021.

[0042] This nested design minimizes the space occupied by the blocking member 203 in the connection slot 2021, making it possible to configure more blocking members 203 on the arm 202. Due to the effective utilization of space, more blocking members 203 can be configured on the arm 202. In this way, when the railing is lowered, it can be ensured that there are enough blocking members 203 to enclose the space below the arm 202, improving the blocking effect. Moreover, the structure is simple, without complex mechanical components, does not require an additional control system to operate, and will not cause the equipment to be overweight, having the advantages of stable structure and high reliability.

[0043] A power motor 11, a rack 12, a driving rod 13 and a number of limiting members are further provided in the connection slot 2021.

[0044] The power output end of the power motor 11 is connected to the rack 12 through a gear transmission mechanism. Therefore, the rack 12 can move along the connection slot 2021 under the drive of the power motor 11. The rack 12 is connected to the driving rod 13. Therefore, the rack 12 can further drive the driving rod 13 to move. In actual arrangement, a slide rail can be configured for the driving rod 13 to achieve guiding. The limiting members include a first connecting rod 14 and a second connecting rod 15 which are hinged. The first connecting rod 14 is hinged to the groove wall of the connection slot 2021, and the second connecting rod 15 is hinged to the driving rod 13.

[0045] After the arm 202 falls, the power motor 11 is started, and the rack 12 is driven to move along the connection slot 2021 through the gear transmission mechanism. The movement of the rack 12 drives the driving rod 13 connected thereto to move. The movement of the driving rod 13 is transmitted through the second connecting rod 15, and then drives the first connecting rod 14 to swing. When the first connecting rod 14 fits with the blocking member 203, limiting is achieved to prevent the blocking member 203 from being pushed open artificially, ensuring the safety of the intersection. Before the arm 202 is lifted, the power motor 11 rotates reversely to pull the rack 12 back to its original position. As the rack 12 retracts, the driving rod 13 also moves accordingly. The linkage of the first connecting rod 14 and the second connecting rod 15 causes the first connecting rod 14 to no longer restrict the retraction of the blocking member 203, allowing the blocking member 203 to automatically retract into the connection slot 2021 under the action of gravity.

[0046] The control host 4 is used to receive signals, process information and issue instructions. The locomotive detection device 1 and the laser sensor 6 are connected to the input port of the control host 4 through cables, and the electric railing machine 2 and the crossing signal machine 5 are connected to the output port of the control host 4 through cables.

[0047] The outdoor cabinet 3 at the level crossing is installed outside the railway level crossing and adopts an outdoor double-layer constant temperature cabinet with dimensions of 1500mm×800mm×600mm. The top is made of 2mm thick galvanized sheet with spray painting, and the bottom is made of 3mm galvanized sheet with spray painting. It has the functions of heat insulation, dust prevention and moisture protection, ensuring normal use at high and low temperatures from -40 to +85°C, with strong sealing and simple maintenance.

[0048] A partition 301 is arranged inside the outdoor cabinet 3 at the level crossing to divide the interior of the outdoor cabinet 3 at the level crossing into an upper space 302 and a lower space 303. The control host 4 is arranged in the upper space 302, and buttons, switches, relays, circuit breakers, transformers, and terminal blocks are arranged in the lower space 303. Through the arrangement of the partition 301, the internal space of the cabinet is effectively utilized. The upper space 302 is used to place the control host 4, and the lower space 303 is used to install electrical components, making the layout more reasonable. Moreover, the electrical components in the lower space 303 are centrally arranged, facilitating the quick positioning and replacement of faulty components by maintenance and repair personnel.

[0049] An alarm button and a reset button are arranged on the control host 4. The alarm button is a momentary double-contact button. When the equipment fails or the level crossing signal machine 5 needs to be debugged, this button can be pressed to start the outdoor audible and visual alarm, and pressing this button again can cancel the alarm, making the control host 4 in the automatic state. The reset button is a self-resetting button, which is used to manually eliminate false alarms caused by various reasons. An up approaching indicator light and a down approaching indicator light are arranged on the control host 4. When the train runs to the position of the corresponding magneto-electric inductor 101, the indicator light lights up to indicate the running direction of the train. The sensor access board, control output board, and signal feedback board of the control host 4 all adopt a modular structure, and the number of main boards can be increased or decreased according to the actual situation at the use site. That is, whether it is a single-track level crossing or a complex level crossing with more than a dozen lines, the internal circuit board can be simply assembled in a modular way to meet the functional requirements.

[0050] A thermostat 304 is also arranged inside the outdoor cabinet 3 at the level crossing. The thermostat 304 includes: a temperature sensor, a heat dissipation device, a heating device, and a micro-control unit; the temperature sensor is connected to the signal input end of the micro-control unit, and the heat dissipation device and the heating device are connected to the control output end of the micro-control unit. When the temperature inside the cabinet is higher than -20 - 55°C, automatic heat dissipation or heating is started. The temperature sensor continuously monitors the temperature change inside the cabinet and converts it into an electrical signal and sends it to the micro-control unit. The micro-control unit is used to process the signal of the temperature sensor and control the heat dissipation device and the heating device according to a preset program. The heat dissipation device can be a fan, which is used to reduce the temperature when the temperature inside the cabinet is too high; the heating device can be a heater or a heating rod, which is used to provide heat when the temperature inside the cabinet is too low.

[0051] The level crossing signal machine 5 is installed at the level crossing of the railway and the road. The level crossing signal machine 5 consists of a frame body 501, and a signal lamp 502, a buzzer 503, a voice player 504 and a warning sign 505 installed on the frame body 501. When a train approaches and passes through the level crossing, it provides simultaneous audible, visual and voice alarms. The buzzer 503 is used to give a sound warning. When a train approaches, the buzzer 503 will emit a loud alarm sound to remind pedestrians and drivers to pay attention to safety. The voice player 504 can play pre-recorded voice warnings, such as "The train is about to pass, please stop and wait", etc., to enhance the warning effect.

[0052] The laser sensor 6 is installed near the level crossing. When a train stays at the railway level crossing, the opposed beam signal of the laser sensor 6 is blocked. When the train passes through the railway level crossing, the laser opposed beam is connected. At this time, it can be determined that the train has passed through the level crossing, and the electric barrier machine 2 can act and the railing can be lifted.

[0053] Monitoring cameras 7 are installed on both sides of the level crossing and are transmitted to the centralized monitoring center of the level crossing through the network to automatically determine whether a vehicle has passed. If there is a train in the specified area, it is judged that the vehicle has not passed. If there is no train in the specified area, it is judged that the train has passed. Together with the laser sensor 6, it forms a double-insurance control system.

[0054] The overall logical function is realized as follows:

[0055] The level crossing signal machine 5 is normally in the white light state. When a train passes through the magneto-electric inductor going up or down, it will automatically alarm, change from white / yellow light to red light and start the voice broadcast function to inform passing vehicles and pedestrians. 10 seconds after the alarm (the time is adjustable), the electric barrier machine 2 performs the action of lowering the pole, and the level crossing is closed. After the train passes, the level crossing stops alarming, the signal lamp switches from red light to white light, and the electric barrier machine 2 performs the raising action. The laser sensors 6 located on both sides of the level crossing are used to detect whether there is a stop at the level crossing. If there is a train staying at the level crossing, the level crossing signal machine 5 is in the alarm state and the electric barrier machine 2 is in the closed state. When there is no train, the electric barrier machine 2 automatically rises and the alarm stops automatically to ensure the safety of the level crossing. The monitoring camera 7 identifies the passing situation of railway passenger and freight cars in the specified area of the level crossing. When there is a vehicle in the area, the railing drops. When there are no passenger or freight cars, it forms a dual control with the laser sensor and the railing rises. The monitoring camera 7 transmits the video information to the centralized management center of the level crossing through the network. The center operator can observe the passing situation of vehicles at the level crossing in real time through the video and can manually control the raising and lowering of the railing in special circumstances.

[0056] It can realize automatic alarm and lowering of the pole when a vehicle approaches. After the vehicle has completely passed, it automatically raises the pole to release the vehicle and personnel. The operators in the centralized management center can also remotely control the raising and lowering of the pole according to the actual situation of the level crossing through the video system and can leave video information for later review.

[0057] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
