Abstract
Description
Technical Field
[0001] This invention relates to the field of roadbed settlement early warning technology, and more specifically, to a contact alarm-type intelligent early warning system for widened roadbed settlement. Background Technology
[0002] With the continuous development of the transportation industry and the ongoing improvement and optimization of existing networks, some existing roads can no longer meet the demands of transportation and need to be widened and expanded. However, due to differences in the mechanical properties of new and old roadbeds, roadbed settlement under traffic loads, especially non-uniform settlement, leads to numerous road disasters. Timely settlement early warning is crucial for disaster prevention. Previously, the identification of roadbed and pavement disasters was mostly done through regular inspections. By the time pavement damage or observable settlement deformation appeared, the disaster was already quite serious. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a contact alarm-based intelligent early warning system for settlement of widened roadbeds.
[0004] Firstly, a contact alarm-type intelligent early warning system for settlement of widened roadbed is provided, including: a contact alarm, a signal receiver, and an intelligent early warning system;
[0005] The contact alarm is installed at the joint between the existing road and the widened road, and emits an alarm signal when the relative deformation between the widened road and the existing road exceeds a preset warning value; the signal receiver is used to receive the alarm signal and send the alarm signal to the intelligent early warning system; the intelligent early warning system is used to receive and identify the alarm signal and form a database.
[0006] Preferably, the contact alarm includes a power supply section and a signal transmitting section. The power supply section is installed on the side closer to the original road, and the signal transmitting section is installed on the side closer to the widened road. The power supply section and the signal transmitting section are welded together.
[0007] The power supply section includes a passive connector, and the signal transmitting section includes an active connector. When there is no settlement or the settlement deformation is less than a preset value, the passive connector and the active connector are not in contact, and the internal circuit of the contact alarm is in an open circuit state. When the settlement deformation reaches the preset value, the passive connector and the active connector are in contact, the internal circuit of the contact alarm is connected, and the signal transmitting section sends an alarm signal.
[0008] Preferably, the passive joint consists of two rigid resistance wires with different resistivities; when the settlement deformation reaches a preset value, the active joint contacts the passive joint, generating a continuous signal; when the settlement type is non-uniform settlement and the settlement deformation reaches the preset value, both rigid resistance wires of the passive joint contact the active joint, generating a larger continuous signal; when the road surface vibrates, the passive joint and the active joint separate automatically after contact, generating a discontinuous current signal; when the road surface is damaged, causing rainwater to infiltrate, a short-circuit current signal is generated.
[0009] Preferably, the power supply section further includes a battery and a power supply section housing, and the signal transmitting section further includes a signal transmitter and a signal transmitting section housing.
[0010] Preferably, the signal receiver is a mobile portable receiver or a fixed receiving tower.
[0011] Secondly, a contact alarm-based intelligent early warning method for settlement of widened roadbeds is provided, executed by any of the contact alarm-based intelligent early warning systems for settlement of widened roadbeds described in the first aspect, including:
[0012] Step 1: When the roadbed deforms, the touch alarm sends an alarm signal containing information about the roadbed deformation to the signal receiver.
[0013] Step 2: The signal receiver receives the alarm signal and sends the alarm signal to the intelligent early warning system;
[0014] Step 3: The intelligent early warning system receives the alarm signal and, based on the initial database, identifies the characteristics of the alarm signal, determines the type of roadbed disaster, and formulates a processing plan that matches the type of roadbed disaster; the characteristics of the alarm signal include signal duration, signal frequency, and signal waveform;
[0015] Step 4: The intelligent early warning system notifies relevant personnel to take action.
[0016] As an alternative, it also includes: Step 5, after the disaster is handled, relevant personnel will feed back the actual disaster situation and the handling plan to the intelligent early warning system to correct and improve the existing database;
[0017] Step 6: The intelligent early warning system continuously attempts to establish a connection between early warning signals, disaster conditions, and corresponding response plans through machine learning methods, ultimately achieving accurate identification of road disasters based on early warning signals.
[0018] Preferably, in step 3, the types of roadbed disasters include: overall roadbed settlement, non-uniform roadbed settlement, road surface vibration, and road surface damage; the alarm signals corresponding to overall roadbed settlement and non-uniform roadbed settlement are continuous signals of different currents, the alarm signal corresponding to road surface vibration is a discontinuous current signal, and the alarm signal corresponding to road surface damage is a short-circuit current signal.
[0019] Thirdly, a method for installing a contact alarm as described in any of the first aspects is provided, including:
[0020] Step 1: After the surface layer of the widened road is poured, grooves are cut at the joint between the original road and the widened road to install the power supply part of the contact alarm.
[0021] Step 2: Fix the power supply part to one side of the slot using structural adhesive, and then connect the signal transmitting part to the power supply part 11 and place it on the other side of the slot;
[0022] Step 3: Adjust the distance between the active and passive connectors to ensure no contact between the connectors and an appropriate warning distance;
[0023] Step 4: Repair the grooved section of the road surface to make it smooth.
[0024] The beneficial effects of this invention are:
[0025] 1. The contact alarm of the present invention has a simple structure and is easy to install. When the relative deformation of the new and old road surfaces exceeds the preset warning value, it can promptly issue an alarm signal.
[0026] 2. The signal receiver of the present invention can be adjusted according to the scale of the project, and can be selected from small mobile receivers to large fixed receiving stations.
[0027] 3. The intelligent early warning system of this invention can predict the type of disaster by the length and frequency of the alarm signal and formulate handling measures. After the disaster is handled, machine learning by comparing the predicted information with the actual situation can further improve the intelligence level of the early warning system.

Detailed Implementation
[0032] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that those skilled in the art can make several modifications to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
[0033] Example 1:
[0034] Embodiment 1 of this application provides a contact alarm-type intelligent early warning system for roadbed settlement after widening. By providing timely early warning of road settlement and deformation after widening, and timely feedback and accurate identification of the early warning signal, it is possible to address road defects in their early stages.
[0035] Specifically, this contact alarm-based intelligent early warning system for widening roadbed settlement, such as... Figure 1 As shown, it includes: a contact alarm 1, a signal receiver 2, and a smart early warning system 3;
[0036] The contact alarm 1 is installed at the joint between the original road and the widened road, and emits an alarm signal when the relative deformation between the widened road and the original road exceeds a preset warning value; the signal receiver 2 is used to receive the alarm signal and send the alarm signal to the intelligent early warning system 3; the intelligent early warning system 3 is used to receive and identify the alarm signal and form a database.
[0037] Specifically, the contact alarm 1 includes a power supply section 11 and a signal transmitting section 12. The power supply section 11 is installed on the side closer to the original road, and the signal transmitting section 12 is installed on the side closer to the widened road. This design enables the system to accurately monitor road settlement and deformation, improving the system's reliability and accuracy. Furthermore, the power supply section 11 and the signal transmitting section 12 are welded together, ensuring a stable connection and preventing false alarms or missed alarms due to loose connections.
[0038] The power supply section 11 includes a passive connector 112, and the signal transmitting section 12 includes an active connector 122. When there is no settlement or the settlement deformation is less than a preset value, the passive connector 112 and the active connector 122 are not in contact, and the internal circuit of the contact alarm 1 is in an open circuit state. When the settlement deformation reaches the preset value, the passive connector 112 and the active connector 122 make contact, the internal circuit of the contact alarm 1 is connected, and the signal transmitting section 12 sends an alarm signal. The preset value can be adjusted according to actual needs. Users can set a suitable preset value for settlement deformation according to specific road conditions and usage requirements to achieve personalized early warning functions.
[0039] This application embodiment can also send different types of alarm signals according to the settlement type, improving the system's flexibility and practicality. For example, the passive connector 112 consists of two rigid resistance wires with different resistivities; when the settlement type is non-uniform settlement and the settlement deformation reaches a preset value, the first rigid resistance wire of the passive connector 112 contacts the active connector 122, generating a first continuous signal; when the settlement type is overall settlement and the settlement deformation reaches a preset value, the second rigid resistance wire of the passive connector 112 contacts the active connector 122, generating a second continuous signal; the resistances connected in the above two cases are different, therefore the magnitudes of the collected continuous current signals differ, which can qualitatively identify the disaster mode.
[0040] Furthermore, the rapid passage of large trucks may cause road vibrations, leading to the spontaneous separation of the passive connector 112 and the active connector 122 after contact, resulting in a discontinuous current signal. Additionally, road surface damage causing rainwater infiltration can generate a short-circuit current signal. Therefore, the signals collected by this device are not limited to current magnitude but also include duration, waveform, and frequency. These electrical signals contain a large amount of road surface deformation information, and signal identification requires subsequent intelligent recognition methods.
[0041] In addition, the power supply section 11 includes a battery 111 and a power supply section housing 113, and the signal transmitting section 12 includes a signal transmitter 121 and a signal transmitting section housing 123. The battery 111, as the energy source of the power supply section 11, provides a stable power supply to the entire system, ensuring its normal operation. The power supply section housing 113 protects the battery 111 from damage or failure due to external environmental influences. Simultaneously, the power supply section housing 113 also provides waterproofing and dustproofing, improving the system's reliability and stability. The signal transmitter 121, as the core component of the signal transmitting section 12, transmits alarm signals, enabling remote monitoring and early warning functions. The protection provided by the signal transmitting section housing 123 effectively prevents the signal transmitter 121 from external interference or damage, ensuring the quality and stability of signal transmission.
[0042] The signal receiver 2 can be a mobile portable receiver 21, a fixed receiving tower 22, or other forms of electronic devices and satellite equipment with receiving chips. This design allows the system to adjust the signal reception method according to the scale of the project.
[0043] Example 2:
[0044] Building upon Example 1, Example 2 of this application provides a contact alarm-based intelligent early warning method for settlement of widened roadbeds. By monitoring the relative displacement between the new and old road surfaces, it provides timely warnings of potential excessive settlement deformation after widening. Then, an intelligent recognition system analyzes the warning signals and provides appropriate response plans. Finally, the system's recommended plan is adjusted according to the site conditions, and the adjustment information is fed back to the intelligent recognition system. Through machine learning, the accuracy of the early warning system is further improved.
[0045] Specifically, such as Figure 3 As shown, it includes:
[0046] Step 1: When the roadbed deforms, the touch alarm 1 sends an alarm signal containing roadbed deformation information to the signal receiver 2.
[0047] Step 2: Signal receiver 2 receives the alarm signal and sends the alarm signal to the intelligent early warning system 3.
[0048] Step 3: The intelligent early warning system 3 receives the alarm signal and, based on the initial database, identifies the characteristics of the alarm signal, determines the type of roadbed disaster, and forms a processing plan matching the type of roadbed disaster. The characteristics of the alarm signal include signal duration, signal frequency, and signal waveform. The types of roadbed disasters include: overall roadbed settlement, non-uniform roadbed settlement, road surface vibration, and road surface damage. The alarm signals corresponding to overall roadbed settlement and non-uniform roadbed settlement are continuous signals of different currents, the alarm signal corresponding to road surface vibration is a discontinuous current signal, and the alarm signal corresponding to road surface damage is a short-circuit current signal.
[0049] Step 4: The intelligent early warning system notifies relevant personnel to take action.
[0050] Step 5: After the disaster is handled, relevant personnel will report the actual disaster situation and the handling plan to the intelligent early warning system 3 to correct and improve the existing database;
[0051] Step 6: The intelligent early warning system 3 continuously attempts to establish a connection between early warning signals, disaster conditions, and corresponding response plans through machine learning methods, ultimately achieving accurate identification of road disasters based on early warning signals. Specifically, the method provided in this embodiment corresponds to the method of the system provided in Embodiment 1. Therefore, the parts in this embodiment that are the same as or similar to those in Embodiment 1 can be referred to each other and will not be repeated in this application.
[0052] Example 3:
[0053] Based on Example 1, Example 3 of this application provides an installation method for a contact alarm, including:
[0054] Step 1: After the surface layer of the widened road is poured, grooves are cut at the joint between the original road and the widened road, and the power supply part 11 of the contact alarm 1 is installed.
[0055] Step 2: Fix the power supply part 11 to one side of the slot using structural adhesive, and then connect the signal transmitting part 12 to the power supply part 11 and place it on the other side of the slot;
[0056] Step 3: Adjust the distance between the active connector 122 and the passive connector 112 so that there is no contact between the connectors and the warning distance is appropriate;
[0057] Step 4: Repair the grooved section of the road surface to make it smooth.
[0058] Specifically, the method provided in this embodiment is the installation method corresponding to the contact alarm provided in Embodiment 1. Therefore, the parts in this embodiment that are the same as or similar to those in Embodiment 1 can be referred to each other, and will not be repeated in this application.
