Railway external environment safety monitoring and early warning device

Abstract

This patent discloses a railway external environment safety monitoring and early warning device, including a lifting mechanism. A stop bar is fixedly installed at the flipping end of the lifting mechanism. The stop bar is hollow inside. A laser ranging sensor is fixedly installed at the front end of the outer wall of the stop bar, and an audible and visual alarm is fixedly installed at the top of the outer wall of the stop bar. The wiring of the laser ranging sensor and the audible and visual alarm is located inside the stop bar. This patent, through the combination of laser ranging sensor, microcontroller, and audible and visual alarm, can detect the distance between the stop bar and surrounding targets in real time. When the distance is less than a preset safety threshold (i.e., the target enters the danger zone), the microcontroller immediately triggers the audible and visual alarm, actively reminding pedestrians and vehicles to stay away through sound and light. This upgrades from "passive obstruction" to "active early warning," solving the core safety loophole of "no warning when approaching a danger zone."

Description

Technical Field

[0001] This patent relates to the field of safety monitoring technology, specifically a railway external environment safety monitoring and early warning device. Background Technology

[0002] Existing guardrails at rural railway crossings only provide basic physical obstruction of the crossing. They cannot detect the distance between pedestrians and vehicles and the guardrails (and the railway tracks behind them). Even if pedestrians and vehicles are close to the guardrails (already in the danger zone near the tracks), the guardrails do not provide any warning. This can easily lead to collisions with trains due to people and vehicles "unconsciously approaching". The existing guardrails do not clearly mark the "safety boundary", and pedestrians and vehicles may mistakenly stop in dangerous areas (e.g., although they have not crossed the guardrails, they are too close to the tracks) because they "don't know how far is safe". Therefore, we propose a railway external environment safety monitoring and early warning device. Utility Model Content

[0003] The purpose of this patent is to provide a railway external environment safety monitoring and early warning device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this patent provides the following technical solution: a railway external environment safety monitoring and early warning device, including a lifting mechanism, a stop bar fixedly installed at the flipping end of the lifting mechanism, the stop bar being hollow inside, a laser ranging sensor fixedly installed at the front end of the outer side wall of the stop bar, and an audible and visual alarm fixedly installed at the top of the outer side wall of the stop bar, with the wiring of the laser ranging sensor and the audible and visual alarm located inside the stop bar;

[0005] A control box is fixedly installed on the top left side of the lifting bar machine. A microcontroller and a battery are fixedly installed inside the control box. A solar panel is fixedly installed on the top outside of the control box. A flexible hose is fixedly installed on the right side of the control box. The other end of the flexible hose is embedded in the top side wall of the stop bar. The two ends of the flexible hose are respectively connected to the inside of the control box and the inside of the stop bar.

[0006] The wiring of the laser rangefinder and the audible and visual alarm passes through the inside of the baffle and the flexible tube and is electrically connected to the microcontroller. The solar panel, the battery and the microcontroller are electrically connected in sequence.

[0007] Preferably, a projection light is fixedly installed on the front end of the outer side wall of the stop bar, and the projection light is electrically connected to the microcontroller.

[0008] Preferably, the hose includes a horizontal tube and a vertical tube, and the ends of the horizontal tube and the vertical tube are fixedly connected to each other.

[0009] Preferably, both the horizontal and vertical tubes include an inner layer, a reinforcing layer is fixedly installed on the outside of the inner layer, and an outer layer is fixedly installed on the outside of the reinforcing layer.

[0010] Preferably, a rope is fixedly installed on the bottom of the outer side wall of the stop bar. There are multiple ropes, which are arranged from left to right on the bottom of the outer side wall of the stop bar, and spikes are fixedly connected to the ropes.

[0011] Preferably, it also includes a support rod, the bottom end of which is fixedly mounted with a base, the base being fixed to the ground, and the top end of the support rod having a rectangular groove, the right side of which is located within the rectangular groove.

[0012] Compared with existing technologies, the beneficial effects of this patent are as follows: This patent, through the combination of a laser rangefinder sensor, a microcontroller, and an audible and visual alarm, can detect the distance between the barrier and surrounding targets in real time. When the distance is less than a preset safety threshold (i.e., the target enters the danger zone), the microcontroller immediately triggers the audible and visual alarm, actively reminding pedestrians and vehicles to stay away through sound and light. This upgrades from "passive obstruction" to "active warning," solving the core safety vulnerability of "no warning when approaching a danger zone." By setting a projection light at the front end of the barrier, with the projection direction facing the ground and able to project words such as "safe position," the "safe distance" is directly visualized on the ground. People and vehicles only need to observe the ground projection markings to clearly understand "not to exceed this position," solving the problem of "vague safety range and difficulty in judgment by personnel," and avoiding dangers caused by cognitive biases.

[0018] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a railway external environment safety monitoring and early warning device, including a lifting mechanism 1, a stop bar 2 fixedly installed at the flipping end of the lifting mechanism 1, the inside of the stop bar 2 is hollow, a laser ranging sensor 3 is fixedly installed at the front end of the outer side wall of the stop bar 2, and an audible and visual alarm 4 is fixedly installed at the top of the outer side wall of the stop bar 2, and the lines of the laser ranging sensor 3 and the audible and visual alarm 4 are located inside the stop bar 2.

[0020] Barrier lifting machine: Refer to the GW7060 high-speed barrier lifting machine. The working power supply is AC220V±20%, 50Hz±5Hz. The fastest running speed can reach 0.6 seconds. The noise is ≤65dB. The working environment temperature is -40°~+70°. The protection level is IP65.

[0021] Laser rangefinder: A short-range, high-precision laser rangefinder can be selected, such as a model with a measurement range of 0.1-5 meters and an accuracy of ±1mm. The specific model can be selected according to actual needs.

[0022] Audible and visual alarm: SZSW2731-CT Solar-powered audible and visual alarm: Powered by solar energy, LED light source, 2000mAh rated battery capacity, 2*0.4W rated power, 5V solar panel input voltage, red light source color, wavelength 620-630nm, color temperature 900K, visibility distance 800-1000M, protection level IP67.

[0023] In some towns and villages, guardrails are installed at railway crossings to block the passage of trains and prevent pedestrians and vehicles from crossing. However, the guardrails are not very effective, and pedestrians or vehicles can easily get close to them, which can lead to them being too close to the railway tracks and potentially causing accidents.

[0024] This device uses a laser rangefinder 3 to measure the distance between the barrier 2 and the vehicle. When the distance is too close, an audible and visual alarm 4 will be activated to remind pedestrians and vehicles to quickly move away to a safe distance and avoid danger.

[0025] A control box 5 is fixedly installed on the top left side of the lifting machine 1. A microcontroller 6 and a battery 7 are fixedly installed inside the control box 5. A solar panel 8 is fixedly installed on the top outside of the control box 5. A flexible hose 9 is fixedly installed on the right side of the control box 5. The other end of the flexible hose 9 is embedded in the top side wall of the stop bar 2. The two ends of the flexible hose 9 are connected to the inside of the control box 5 and the inside of the stop bar 2, respectively.

[0026] Microcontrollers: Consider using microcontrollers based on the ARM architecture, such as the STM32 series. The specific model can be determined based on the requirements of the number of sensor interfaces, processing power and power consumption. For example, the STM32F103 series has rich peripheral interfaces and can meet the data acquisition and processing needs of multiple sensors.

[0027] Battery: A 12V lead-acid battery or lithium battery with a capacity of 2000mAh-5000mAh can be selected. The specific capacity can be determined according to the power consumption and working time requirements of the device.

[0028] Solar panels: 5W-10W solar panels can be selected, such as the 5W shell-type glass solar panel with model SSE176173MG, which has a peak power of 5W, working voltage of 5.5V, maximum working current of 900mA, conversion efficiency of ≥21%, and waterproof rating of IP65.

[0029] The wiring of the laser rangefinder 3 and the audible and visual alarm 4 passes through the inside of the baffle 2 and the hose 9 and is electrically connected to the microcontroller 6. The solar panel 8, the battery 7 and the microcontroller 6 are electrically connected in sequence.

[0030] Specifically, a projection lamp 10 is fixedly installed on the front end of the outer side wall of the stop bar 2, and the projection lamp 10 is electrically connected to the microcontroller 6.

[0031] Projector: HGLED-TG-004 series outdoor waterproof projector can be selected. The power can be selected according to actual needs, such as 50W or 100W. The input voltage is AC100-277V 50Hz, the luminous efficacy is 110-140Lm / W, the color rendering index is ≥80Ra, the color temperature is 3000k-6500k, and the protection level meets the requirements for outdoor use.

[0032] The spotlight projects towards the ground, projecting warnings such as "safe location." The projected area on the ground indicates a safe distance, reminding people and vehicles not to exceed the projected area.

[0033] Specifically, the hose 9 includes a horizontal tube 11 and a vertical tube 12, with the ends of the horizontal tube 11 and the vertical tube 12 being fixedly connected to each other.

[0034] Specifically, both the horizontal tube 11 and the vertical tube 12 include an inner layer 13, a reinforcing layer 14 is fixedly installed on the outside of the inner layer 13, and an outer layer 15 is fixedly installed on the outside of the reinforcing layer 14.

[0035] The material of the reinforcing layer 14 allows the hose to bend to accommodate the movement and flipping of the stop lever 2, while preventing the hose from collapsing and thus avoiding damage to the internal wiring.

[0036] Hose: Metal corrugated hoses or PVC hoses with reinforcing layers can be selected. For example, the inner layer is an insulating material, the reinforcing layer is a stainless steel wire or fiber braided layer, and the outer layer is a wear-resistant PVC material. The specific model can be determined according to the requirements of inner diameter, length and bending radius.

[0037] Specifically, a rope 16 is fixedly installed on the bottom of the outer side wall of the stop bar 2. There are multiple ropes 16, which are arranged from left to right on the bottom of the outer side wall of the stop bar 2. Spikes 17 are fixedly connected to the ropes 16.

[0038] The spike 17 is designed to deter children from crawling under the barrier 2.

[0039] Specifically, it also includes a support rod 18, with a base fixedly installed at the bottom of the support rod 18, the base being fixed to the ground, and a rectangular groove at the top of the support rod 18, with the right side of the stop bar 2 located within the rectangular groove.

[0040] Working principle: When a train is about to appear at the level crossing, the staff can control the lifting machine 1 to place the guardrail 2 horizontally. The laser range sensor 3 continuously emits a laser beam and receives the reflected signal. Based on the round-trip time of the signal, the distance between the vehicle or pedestrian and the guardrail is calculated and transmitted to the microcontroller 6. The microcontroller 6 analyzes the received distance data in real time and compares it with a preset safety threshold. When the distance is less than the safety threshold, the microcontroller 6 immediately triggers the audible and visual alarm 4 to issue an alarm signal, reminding personnel to quickly evacuate the position of the guardrail 2.

[0041] The data processing unit analyzes the received distance data in real time and compares it with a pre-set safety threshold. When the distance is less than the safety threshold, the data processing unit immediately triggers an audible and visual alarm device, issuing an alarm signal.

[0042] The power supply system monitors the charging status of the solar panels and the battery charge in real time to ensure a stable power supply for the system in various environments.
