Description

Technical Field

[0001] This utility model relates to the field of railway safety management, and in particular to an intelligent safety assistance device for railway level crossings. Background Technology

[0002] The level crossing is located outside the maintenance depot, and high-speed trains may use it for passage or parking on a daily basis. Current safety measures rely primarily on manual operation. When the station duty officer receives a train passage plan, they immediately notify the high-speed train dispatcher. The dispatcher then instructs the overhead contact line workers to go to the level crossing for safety measures and, via walkie-talkie, instructs the security booth staff to close the main gate to ensure on-site safety.

[0003] Furthermore, the high density of people and frequent passage of large vehicles at level crossings significantly increases the difficulty of safety precautions. One side of the level crossing is equipped with a controllable sliding gate, operated by security personnel at the guard post, which effectively manages and controls the flow of people and vehicles. However, the other side relies on manual control, which is clearly insufficient. In situations of high pedestrian density and frequent large vehicle traffic, this can easily lead to operational errors or untimely protection, increasing safety risks. For example, if some large vehicle drivers disobey instructions and force their way across the level crossing, it could cause a major accident.

[0004] Based on on-site surveys and analysis, the existing safety protection measures for level crossings have obvious shortcomings, mainly reflected in untimely information transmission, inadequate personnel observation, and limited protective measures. These problems are particularly prominent in complex environments with dense crowds and frequent vehicle traffic, seriously affecting the safety of level crossings. Summary of the Invention

[0005] The purpose of this utility model is to provide a smart safety protection device for railway level crossings, so as to solve the pain points of existing level crossing safety protection measures mentioned in the background art, thereby eliminating safety risks and improving the level of standardized labor safety management in EMU depots.

[0006] The present invention adopts the following technical solution:

[0007] A smart safety protection device for railway level crossings includes an installation base. A telescopic gate assembly is installed on the top of the installation base. The telescopic gate assembly includes several gate bodies, which are fixedly connected to the top of the installation base and are symmetrically distributed on the top of the installation base. Gate jambs are fixedly connected to both sides of each gate body. Two gate jambs are fixedly connected to the top of the installation base and are symmetrically distributed on both sides of each gate body. A hinge is fixedly connected to one side of each gate jamb, and the gate jambs are movably connected to the gate bodies via the hinges. A motor is fixedly connected to the bottom of one side of each gate jamb. An active crank is fixedly connected to the bottom of the motor. A rocker arm is fixedly connected to the other end of the active crank. A connecting rod is fixedly connected to one side of the rocker arm, and a connecting piece is fixedly connected to one side of the connecting rod. The connecting piece is fixedly connected to the bottom of the gate body.

[0008] Preferably, a security guard arrival button is fixedly connected to the top of the mounting base. This project integrates a telescopic gate, a folding gate, an alarm, an alarm light, a security guard arrival electrical control system, and a dispatch console, realizing intelligent and automated security protection at the crossing. It can automatically control the opening and closing of the gate according to different security states, and can monitor the arrival status of security guards and grid workers in real time when the crossing is armed, ensuring the safety and real-time response capability of the crossing area.

[0009] Preferably, the security guard positioning buttons are located on opposite sides of the gate, and the security guard positioning buttons and the network security guard positioning buttons are symmetrically distributed. The auxiliary defense device adopts LoRa wireless communication technology, which realizes efficient signal transmission between various actuators. The LoRa transmission module connects the dispatch console with the telescopic gate, folding gate, alarm lights, and network security electrical control system, ensuring the stability and real-time performance of data transmission between devices, reducing the dependence on wired transmission, enhancing the system's flexibility and anti-interference ability, and providing an efficient and reliable solution for the safety management of level crossings.

[0010] Preferably, the security guard arrival buttons are located on opposite sides of the gate, and the security guard arrival buttons and the security guard arrival buttons are symmetrically distributed. The auxiliary defense device is designed with strict hierarchical management of control permissions. When the crossing is armed, the dispatcher has the highest control authority, while the remote control functions of the security guard and the security guard are locked, preventing gate control operations. This avoids misoperation or unauthorized intervention. Their respective control rights are restored after the crossing is dearmed. In addition, the device is equipped with an emergency backup remote control channel to ensure that the gate can be quickly controlled to open and close in case of system abnormality. This creates a safety redundancy configuration, improves the reliability and security of the system, and provides multi-level control protection for the safety management of level crossings.

[0011] Preferably, a support frame is fixedly connected to the top of the mounting base, and a touch screen is fixedly connected to the top of the support frame. To ensure the effective transmission of safety information, the auxiliary defense device combines visual (level crossing side warning lights, dispatch control console breathing lights) and audible and visual (level crossing side siren) alarm methods, which can promptly warn employees in different states. During the defense process at the level crossing, the warning lights will reflect the current status in real time. Through the switching of red and green warning lights and the sounding of the siren, employees can intuitively understand the vehicle crossing status at the level crossing, thereby improving the response speed and accuracy of on-site operations.

[0012] More preferably, a connecting bracket is fixedly connected to the top of the mounting base, and an alarm light is fixedly connected to the top of the connecting bracket.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, the project integrates a telescopic gate, a folding gate, an alarm, an alarm light, a power control system for security personnel and guards, and a dispatch console, realizing the intelligent and automated security protection of the crossing. It can automatically control the opening and closing of the gate according to different security states, and can monitor the arrival of security personnel and guards in real time when the crossing is armed, ensuring the safety and real-time response capability of the crossing area.

[0015] 2. In this utility model, the auxiliary defense device adopts LoRa wireless communication technology, which realizes efficient signal transmission between various execution elements. The LoRa transmission module connects the dispatch console with the telescopic gate, folding gate, alarm lights, and the network security electrical control system, ensuring the stability and real-time performance of data transmission between devices, reducing the dependence on wired transmission, enhancing the system's flexibility and anti-interference ability, and providing an efficient and reliable solution for the safety management of level crossings.

[0016] 3. In this utility model, the auxiliary defense device is designed with strict hierarchical management of control authority. When the crossing is armed, the dispatcher has the highest control authority, while the remote control functions of the network engineer and security guard are locked, preventing them from performing gate control operations. This avoids misoperation or unauthorized intervention. Their respective control rights are restored after the crossing is dearmed. In addition, the device is also equipped with an emergency backup remote control channel to ensure that the gate can be quickly controlled to open and close in case of system abnormality. This creates a safety redundancy configuration, improves the reliability and safety of the system, and provides multi-level control protection for the safety management of level crossings.

[0017] 4. In this utility model, in order to ensure the effective transmission of safety information, the auxiliary defense device combines visual (level crossing side warning light, dispatch control console breathing light) and audible and visual (level crossing side siren) alarm methods, which can promptly issue warnings to employees in different states. During the defense process at the level crossing, the warning light will reflect the current status in real time. Through the switching of red and green warning lights and the sounding of the siren, it is ensured that employees can intuitively understand the vehicle crossing status at the level crossing, thereby improving the response speed and accuracy of on-site operations.

The jamb 803 is movably connected to the door body 801 through the hinge 802. A motor 804 is fixedly connected to the bottom of one side of the jamb 803. An active crank 805 is fixedly connected to the bottom of the motor 804. A rocker arm 806 is fixedly connected to the other end of the active crank 805. A connecting rod 807 is fixedly connected to one side of the rocker arm 806. A connecting piece 808 is fixedly connected to one side of the connecting rod 807. The connecting piece 808 is fixedly connected to the bottom of the door body 801.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a security positioning button 2 and a security guard positioning button 3 are fixedly connected to the top of the mounting base 1. The security positioning buttons 2 are located on opposite sides of the door 801, and the security positioning buttons 2 and the security guard positioning buttons 3 are symmetrically distributed.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support frame 4 is fixedly connected to the top of the mounting base 1, a touch screen 5 is fixedly connected to the top of the support frame 4, a connecting bracket 6 is fixedly connected to the top of the mounting base 1, and an alarm light 7 is fixedly connected to the top of the connecting bracket 6.

[0030] The method of use and advantages of this utility model: The intelligent safety assistance device for railway level crossings operates as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the intelligent security coordination device consists of a telescopic gate, a folding gate, a network worker arrival control box, a security guard arrival control box, a security guard arrival status button box, an alarm, an alarm light 7, and a dispatch control console. The components communicate via a LoRa wireless transmission scheme. When each actuator receives a corresponding signal, it automatically performs the corresponding action, such as sounding the alarm, turning the alarm light 7 red, and closing the gate. In the armed state at the crossing, the touchscreen 5 on the dispatch control console will display the arrival status of the network worker and security guard in real time. When the network worker and security guard press the arrival button, the control console receives the wireless signal and the touchscreen... The corresponding arrival status indicator light on screen 5 will turn green, thus providing feedback to the dispatcher on the arrival status of the network worker and security guard. At this time, the alarm's buzzer function will be deactivated, and the retractable gate and folding gate will close simultaneously. This solution effectively solves four key technical problems by realizing three-way linkage control among dispatchers, security guards, and network workers, and integrating visual and audio-visual auxiliary functions. These problems include untimely dispatcher notification response, insufficient visibility for train drivers, untimely communication of level crossing closure information, and limited protective measures. This improves the level crossing safety management level and ensures the personal safety of trains and pedestrians.
