Description

Technical Field

[0001] The utility model relates to the technical field of route monitoring, and in particular discloses a route sudden blocking accident monitoring and alarm device. Background Art

[0002] Highway and rail networks often cross mountains, canyons, and rivers, necessitating the construction of numerous bridges, high embankments, deep excavations, and other infrastructure. Bridge and embankment sections often experience bridge and roadbed collapses due to adverse weather conditions, quality defects, and other unforeseen circumstances. In excavated sections, route blockages due to slope collapses are also common. When sudden collapses and other blockages occur in highway and rail networks, if these blockages are not immediately detected and an alarm is not issued to oncoming vehicles, cars or trains can crash or collide, causing significant loss of life and property. Therefore, monitoring routes for blockages, issuing immediate alarms in the event of collapses or burials, and intercepting vehicles approaching the affected section are critical challenges that urgently need to be addressed.

[0003] Monitoring routes for blockages and immediately reporting them to the police currently faces the following challenges:

[0004] First, there's the economic feasibility of monitoring and alarming. While sudden route blockages can have extremely serious consequences, their overall probability is low, and using expensive equipment to monitor all routes is generally uneconomical. Therefore, a practical monitoring and alarm system must be low-cost and easy to implement.

[0005] Secondly, monitoring and reporting to the police requires a rapid response. A road blockage immediately threatens vehicle safety. On a busy highway, if an alert isn't issued immediately, dozens of vehicles could be lost within minutes. Therefore, the methods some technicians have proposed to infer road blockages based on digital information like navigation, big data, and lidar don't respond quickly enough.

[0006] Third, monitoring and alarms must be highly reliable. Traffic stoppages and control based on monitoring results impact the overall safety and smooth flow of the entire transportation network, so the monitoring methods and systems must be highly reliable. First, the monitoring device must be immune to external environmental influences, such as electromagnetic fields, light, heat, and water, to avoid false triggering. Second, the monitoring device itself must be highly reliable, capable of self-checking or regular inspections to ensure its integrity, and requiring minimal maintenance. Current video surveillance and electromagnetic wave monitoring technologies struggle to meet these requirements.

[0007] In summary, in the face of major traffic accidents and loss of life and property that may be caused by sudden route blockage, there is an urgent need to provide a monitoring device that is low-cost, easy to implement, fast-response, and highly reliable. Utility Model Content

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides a route sudden blockage accident monitoring and alarm device, comprising a unidirectional conducting parallel resistor array 10, a circuit monitoring module 20, and an alarm module 30. The unidirectional conducting parallel resistor array 10 comprises a pair of conductors 11 arranged to form a loop, a plurality of unidirectional conducting modules 12 connected in series to the conductors 11, and a plurality of resistor units 13 connected in parallel between the two conductors 11. The input end of the circuit monitoring module 20 is connected to the unidirectional conducting parallel resistor array 10, and the output end of the circuit monitoring module 20 is electrically connected to the alarm module 30. The circuit monitoring module 20 is configured to detect the circuit resistance of the unidirectional conducting parallel resistor array 10 and compare it with a preset resistance threshold. If the circuit resistance is greater than the preset resistance threshold, it indicates that the unidirectional conducting parallel resistor array has broken within a set range. The output end then outputs an intact or broken state, controlling the alarm module 30 to generate an alarm. In this embodiment, the circuit monitoring module 20 utilizes an existing functional module. The alarm module 30 may also utilize an existing functional module, such as an audible and optical alarm. The alarm module is a module that can issue audible, visual, or textual warnings based on the output of the detection module. This includes, but is not limited to, traffic lights installed on road studs, traffic lights on or above the road, or information boards. Specifically, the alarm module 30 of this embodiment utilizes an indicator light alarm module. If the circuit monitoring module 20 identifies that the circuit resistance of the unidirectional parallel resistor array 10 is greater than a preset resistance threshold, the indicator light alarm module is controlled to display a red light, indicating that the unidirectional parallel resistor array is broken within a set range, and outputs a broken status indication via the output terminal. If the circuit monitoring module 20 identifies that the circuit resistance of the unidirectional parallel resistor array 10 is less than or equal to the preset resistance threshold, the indicator light alarm module is controlled to display a green light, indicating that the unidirectional parallel resistor array is not broken within the set range, and outputs a healthy status indication via the output terminal.

[0033] Furthermore, in the above structure, see Figures 1 to 3The route sudden blockage accident monitoring and alarm device provided in this embodiment comprises multiple unidirectional conducting modules 12 distributed at equal intervals on a conductor 11. Multiple resistor units 13 are distributed at equal intervals between two conductors 11. The unidirectional conducting modules 12 and the resistor units 13 can be provided separately or integrated. For example, an integrated design of luminous road studs can be used on a highway, and the array spacing can be set according to different driving speeds and safe stopping distances. The unidirectional conducting modules 12 use diode electronic components or circuit modules with unidirectional energy conduction functions. The resistor units 13 use resistor electronic components with uniform resistance values ​​or circuit modules with stable resistance values. The alarm module 30 uses an audible and visual alarm module and / or a display alarm module. Preferably, the conductor 11 is a commonly used conductor in engineering and industrial fields. Specifically, the circuit monitoring module 20 includes a detection module and a power supply connected to the detection module. The detection module is electrically connected to the unidirectional conducting parallel resistor array 10 and is used to detect the circuit resistance of the unidirectional conducting parallel resistor array 10. The power supply is one or more of a solar module, a button battery, and a piezoelectric energy storage battery. The route blockage monitoring and alarm device provided in this embodiment can be embedded in a groove along the lane markings in the middle of the road to monitor for road collapse. To improve monitoring precision, multiple route blockage monitoring and alarm devices can be deployed across the road cross section.

[0034] like Figures 1 to 3 As shown, the route sudden blockage accident monitoring and alarm device provided in this embodiment has the following working principle:

[0035] Assume that the safe stopping distance is L, the array spacing is X, the number of parallel resistors within the safe stopping distance L is L / X, the resistance of the resistor unit is K, and the resistance of L / X resistor units in parallel is KX / L. The resistance threshold of the circuit monitoring module 20 is set to KX / L. Since the unidirectional conduction module 12 can only conduct in the direction of travel, each circuit monitoring module 20 can detect all parallel resistor units in the forward direction. When the circuit resistance detected by the circuit monitoring module 20 is less than or equal to KX / L, it indicates that the route within the safe stopping distance ahead is not blocked (all parallel resistor units are intact), and the alarm module 30 does not need to activate the alarm (e.g., display a green light or no display). When the circuit resistance detected by the circuit monitoring module 20 is greater than KX / L, it indicates that the route within the safe stopping distance ahead is blocked (fewer than L / X parallel resistor units), and the alarm module 30 activates the alarm (e.g., displays a red light).

[0036] Therefore, after installing the monitoring and alarm device for sudden route blockage accidents, if the route is not blocked, all alarm modules 30 will display green or no display. Once the line collapses and blocks, all alarm modules 30 within a safe stopping distance from the collapse block position will send out an alarm signal, such as displaying a red light.

[0037] Using the solution provided by this embodiment, the unidirectionally conductive parallel resistor array 10 can be continuously produced and extended unrestricted along a route, facilitating industrial mass production and deployment. The circuit monitoring module 20 and the alarm module 30 can be connected to any location on the unidirectionally conductive parallel resistor array 10 and can both monitor and alarm the route status within the safe stopping distance ahead in the direction of travel. This provides low cost, easy implementation, rapid response, and high reliability.

[0038] The implementation scheme of the route sudden blockage accident monitoring and alarm device provided in this embodiment is as follows:

[0039] First, use methods such as groove embedding or surface bonding to firmly connect the unidirectional conductive parallel resistor array to the line (roadbed, pavement, roadbed or rail) along the direction of the route. The length range includes the monitored section and extends to at least a safe stopping distance in the direction of oncoming vehicles (taking into account a certain margin factor, the same below).

[0040] Second, outside the safe stopping distance range of the monitored road section in the direction of oncoming vehicles, one or a group of circuit monitoring modules are connected to the unidirectional conducting parallel resistor array, and the circuit monitoring module is connected to the alarm module.

[0041] Third, after the monitoring alarm for sudden route blocking accidents is installed, the resistance of the unidirectional conducting parallel resistor array is continuously monitored.

[0042] Fourth, analysis and alarm. The resistance threshold is set to the resistance of the parallel resistors within the safe stopping distance ahead. If the detected resistance is less than the parallel resistance of all resistors within the safe stopping distance ahead, the route within the safe stopping distance ahead is intact. If the detected resistance is greater than the safe stopping distance ahead, the route within the safe stopping distance ahead is blocked. However, if the detected route ahead is blocked, an alarm message is output to the alarm module, triggering the alarm and instructing the vehicle to make an emergency stop.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Clearly, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, to the extent such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to encompass such changes and modifications.
