Description

Technical Field

[0001] This invention relates to the field of height restriction detection technology, specifically to a collision alarm sensor device for railway height restriction frames. Background Technology

[0002] According to the "Rules for Repairing Railway Bridges and Tunnels," "For grade-separated bridges and culverts where motor vehicles pass under railway lines, if the clearance height under the bridge or culvert is less than 5 meters, height restriction protection frames should be installed in accordance with relevant regulations. Safety protection facilities should be installed on grade-separated bridges crossing railway lines in accordance with relevant regulations." Currently, height restriction protection mainly uses portal-type height restriction protection frames. This type of protection is a passive form of protection. Once oversized vehicles enter, it is easy to cause damage to the protection frames and collisions with oversized vehicles. This not only increases the maintenance costs of protection facilities significantly, but also, due to the untimely clearing of the protection frames, can easily cause secondary damage to people and vehicles. In serious cases, it can lead to damage to the bridge or culvert, affecting railway traffic safety.

[0003] To support the construction of a dynamic database and open intelligent monitoring platform for railway external environmental safety hazards, reduce unnecessary malfunctions, accidents, and losses, and ensure the safety and stability of railway operations, it is urgently necessary to build a railway bridge and culvert protection alarm device to improve the timeliness of problem detection, enhance management precision, and ensure the real-time status of managed objects. Summary of the Invention

[0004] The purpose of this invention is to provide a railway height restriction frame collision alarm sensor device that effectively improves the timeliness of problem detection, enhances management accuracy, and ensures the real-time status of managed objects.

[0006] Furthermore, a limiting member matching the shape of the power supply is fixedly connected inside the housing.

[0007] Furthermore, the housing includes a lower mounting frame and an upper cover, with a waterproof sealing strip between the lower mounting frame and the upper cover for waterproofing. The lower mounting frame and the upper cover together form an accommodating cavity for accommodating the power supply and control motherboard.

[0008] Furthermore, the lower mounting frame is fixedly connected to both sides with mounting ears for fixed connection with the carrier, the mounting ears are provided with mounting holes, and the bottom of the lower mounting frame is provided with screw holes for matching and fixed connection with the upper cover.

[0009] Furthermore, the communication unit includes a radio frequency transceiver circuit for near-field communication.

[0010] Furthermore, the detection unit includes a triaxial accelerometer circuit.

[0011] Furthermore, a power management circuit is electrically connected between the main control unit and the power supply.

[0012] A method for detecting collision alarm sensors on railway height restriction frames includes triggering a wake-up mechanism immediately when the detection unit detects a change in acceleration of a certain intensity, waking up the main control unit, communication unit, and power management unit to enter normal working state, transmitting data from the detection unit to the main control unit, processing the received data and generating alarm information through the main control unit, and transmitting the alarm information to the detection terminal through the communication unit.

[0019] Numerous details are explored in the following description to provide a more thorough explanation of embodiments of the invention; however, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details.

[0020] Please see Figure 1 and Figure 2 A collision alarm sensor device for railway height restriction frames includes a housing 3, within which a power supply 1 and a control motherboard 2 are disposed. The power supply 1 is used to supply power to the control motherboard 2. The control motherboard 2 includes a main control unit, a communication unit, and a detection unit. The main control unit is electrically connected to the communication unit and the detection unit, respectively.

[0021] Please see Figure 1 The housing 3 is fixedly connected with a limiting member 4 that matches the shape of the power supply 1.

[0022] Please see Figure 1 The housing 3 includes a lower mounting frame 31 and an upper cover 32. A waterproof sealing strip 5 for waterproofing is provided between the lower mounting frame 31 and the upper cover 32. The lower mounting frame 31 and the upper cover 32 together form an accommodating cavity for accommodating the power supply 1 and the control motherboard 2.

[0023] Please see Figure 1 The lower mounting frame 31 has mounting ears 6 fixedly connected to both sides for fixed connection with the carrier. The mounting ears 6 have mounting holes 7. The bottom of the lower mounting frame 31 has screw holes for fixed connection with the upper cover 32.

[0024] Please see Figure 2 The communication unit includes a radio frequency transceiver circuit for near-field communication.

[0025] Please see Figure 2 The detection unit includes a triaxial accelerometer circuit.

[0026] Please see Figure 2 The main control unit is electrically connected to the power supply 1 via a power management circuit.

[0027] A method for detecting collision alarm sensors on railway height restriction frames includes triggering a wake-up mechanism immediately when the detection unit detects a change in acceleration of a certain intensity, waking up the main control unit, communication unit, and power management unit to enter normal working state. The detection unit transmits data to the main control unit, which processes the received data and generates alarm information. The alarm information is then transmitted to the detection terminal via the communication unit.

[0028] Working principle: After the control motherboard 2 is connected to the power supply 1, it is fixedly installed in the inner cavity of the housing 3. A waterproof sealing ring is installed to provide waterproof and dustproof protection. The top cover 32 is fastened, and the power supply 1 is limited by the limiting component 4 to ensure that the power supply 1 maintains mechanical stability under impact conditions and prevents the battery pack from loosening due to collision, which would affect the normal operation of the device. The lower mounting frame 31 is fixedly connected to the top cover 32 by bolts passing through the screw holes at the bottom of the lower mounting frame 31, thereby sealing the top cover 32 and further enhancing the waterproof and dustproof function. Power Supply 1 provides power to the device. To effectively extend battery life, reduce battery replacement frequency, and improve the ease of use of the sensor device, a low-power wake-up program is implemented. When no collision event occurs, the sensor is in a low-power sleep state, minimizing the power consumption of each module to conserve battery power. When the detection unit detects a change in acceleration of a certain intensity, it immediately triggers the wake-up mechanism, waking up the main control unit, communication unit, and Power Supply 1 management unit, bringing them into normal operation. The detection unit transmits data to the main control unit, which processes the received data and generates alarm information, which is then transmitted to the detection terminal via the communication unit. Power Supply 1 provides stable power support for the normal operation of the device through its management circuit. The communication unit includes a 433MHz radio frequency transceiver circuit, possessing strong signal transmission capabilities. In open environments, its communication distance can reach 80 meters. This enables the sensor device to effectively communicate with receiving devices over a wide range, making it suitable for applications with high communication distance requirements. The detection unit includes a triaxial accelerometer circuit. The impact detection range of the triaxial accelerometer can be adjusted via software programming or external settings. The sensor's detection sensitivity to collisions of different intensities can be flexibly set according to the needs of actual application scenarios, enabling the sensor to better adapt to various complex working environments and application requirements. This invention effectively improves the timeliness of problem detection, enhances management accuracy, and ensures the real-time status of managed objects.
