Description

Technical Field

[0001] The utility model belongs to the technical field of bridge and road safety monitoring and early warning, and mainly relates to a bridge collapse and circuit breaker monitoring and early warning system. Background Art

[0002] A bridge is a structure used by railways, roads, canals, pipelines, and other structures to cross rivers, valleys, or other transportation routes. As a key component of the transportation network, the safe operation of bridges is crucial to protecting people's lives and property and socioeconomic development. During use, bridges are subjected to repeated loads and erosion by the natural environment, which can cause material fatigue damage. This can gradually reduce the safety performance of the bridge and even cause collapse in severe cases. Therefore, the requirements for its safety monitoring and emergency warning systems are also increasing. Conventional bridge monitoring mainly uses sensors to monitor the bridge's status, and obtains the real-time safe operation status of the bridge based on the data sent back by the sensors, or uses visual recognition methods to detect cracks and collapse of the bridge. Both sensor solutions and video AI monitoring solutions require stable power and network support to achieve continuous real-time data collection.

[0003] Application No. 201010162873.4 discloses a method and device for post-bridge collapse traffic alarms. The device includes a power supply, a current-limiting resistor, a warning light, a horn, and a monitoring wire installed beneath the bridge. The monitoring wire, power supply, and current-limiting resistor are connected in series, while the warning light and horn are connected in parallel to the monitoring wire. This device has a simple structure, is easy to implement, and has low maintenance costs. It can prevent vehicles from continuing to move forward after a bridge collapse, which could lead to significant casualties and injuries to vehicles and personnel. It is suitable for all post-bridge collapse traffic alarms. However, when this alarm method and device are used, power and network outages are often associated with road and bridge collapses. This can cause the sensor monitoring device and monitoring solution to function improperly, meaning that an immediate response is impossible in an emergency. Furthermore, even if an abnormality can be detected, timely and effective communication of the warning information to relevant personnel and vehicles to avoid or minimize damage caused by secondary accidents remains a technical challenge. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge collapse and circuit breaker monitoring and early warning system to solve the problem in the above-mentioned background technology that when existing roads and bridges collapse, the sensor monitoring device and monitoring cannot operate normally and cannot provide real-time early warning based on the predicted bridge collapse risk.

[0005] The utility model adopts the following technical solutions: a bridge collapse and circuit breaker monitoring and early warning system, including a UPS power module, a data acquisition and processing module and an early warning module; the UPS power module includes a solar panel, a lithium battery and a UPS power supply, and the solar panel and the lithium battery provide power for the UPS power module; the data acquisition and processing module includes a host computer, an optical terminal A-end transmitter, an optical terminal B-end receiver and a relay; the host computer and the optical terminal A-end transmitter, the optical terminal B-end receiver and the relay are all connected to each other through a serial line; the optical terminal A-end transmitter and the optical terminal B-end receiver are connected through an optical fiber; the early warning module includes two early warning contents: lithium battery power warning and road connection and disconnection warning, and the warning position is divided into local warning and remote display terminal warning, and the remote display terminal warning includes remote monitoring large screen warning and remote mobile phone warning.

[0006] The early warning system is set up as a dual-loop design, with two loops set up in each direction of the bridge. The loop cables should be arranged along the length of the bridge and extend a certain distance beyond the bridge deck. Backups should be set up for all key components to ensure that changes can be detected in time when the bridge collapses.

[0007] The host computer is equipped with an Internet of Things card to forward low-battery warning information to a remote display terminal, including real-time monitoring of the large screen and remote mobile phone warnings.

[0008] The local warning includes a high-decibel voice warning, which is a road scene warning. The warning content is a road accessibility warning, which is used to remind vehicles to pay attention to timely avoid risks.

[0009] The remote monitoring large-screen warning includes voice warning and screen display; the remote mobile phone warning includes pop-up notification and voice warning.

[0010] The data acquisition and processing module and the early warning module are connected to the UPS power module lithium battery load through cables.

[0011] The lithium battery mainly provides power for the host computer, the transmitting end of the optical terminal A, the receiving end of the optical terminal B and the local early warning system.

[0012] The lithium battery power warning is that the lithium battery controller is connected to the host computer through the 485 serial port, and the host computer continuously polls the lithium battery power status through the COM5 serial port.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) This bridge collapse monitoring system is simple. When a road bridge collapses and the cable is disconnected, the sound and light alarm relies on the UPS uninterruptible power supply after the power outage. It can achieve local early warning without the need for an external network and alert vehicles in the lane at a safe distance outside the collapsed section.

[0015] (2) Combined with the Internet of Things card network, remote transmission of on-site road and bridge collapse conditions can be achieved, and road conditions can be viewed in real time on mobile phones, making it convenient for road management departments to promptly detect and warn and take effective measures such as cutting off roads, effectively preventing the disaster from further expanding.

[0024] The optical fiber of the transmitting end of the optical terminal A and the receiving end of the optical terminal B is set to a dual-loop design. The optical fiber extends from the transmitting end of the optical terminal A and is connected to the receiving end of the optical terminal B after the bridge is laid. Two loops are set in each direction of the bridge. The loop optical fiber should be arranged along the length of the bridge and extend beyond the bridge deck for a certain distance. Backups are set for all key components to ensure that changes can be detected in time when the bridge collapses. The loop cable here is set to extend beyond the bridge deck for a distance of not less than 2000 meters to ensure that there is enough safe distance for vehicles to slow down. This design can ensure that even in the event of a bridge collapse, the driver can be reminded to slow down or stop at a safe distance, thereby avoiding the occurrence of secondary accidents. The dual-loop design can ensure that even if one loop fails, the other loop can still continue to work, ensuring the continuity and reliability of the system.

[0025] The data acquisition and processing module and the early warning module are connected to the lithium battery load of the UPS power module through cables; the lithium battery mainly provides power for the host computer, the transmitting end of the optical terminal A, the receiving end of the optical terminal B and the local early warning system; the lithium battery power warning is that the lithium battery controller is connected to the host computer through the 485 serial port, and the host computer continuously polls the lithium battery power status through the COM5 serial port; here, when the power is higher than the warning value by 20%, no action is performed, and when the power is lower than the warning value, the host computer will issue a power warning; the host computer is equipped with an Internet of Things card, which forwards the low power warning information to the remote display terminal, including the real-time monitoring large screen and Remote mobile phone warning; here, when the mobile phone receives the battery warning information, manual intervention is required to replace the power supply; the local warning includes a high-decibel voice warning, which is a road scene warning, and the warning content is a road access warning, which is used to remind vehicles to pay attention to timely avoid risks; the remote monitoring large-screen warning includes voice warning and screen display; the remote monitoring large-screen warning content is lithium battery power warning and road access warning, and the warning method is a large-screen voice prompt, and the prompt content includes lithium battery power and road access; the screen display can display the lithium battery power status and road access status on the screen in real time. When the lithium battery power status is positive It always displays green. When the lithium battery power is less than 20%, the lithium battery power status is displayed in red. When the road accessibility is normal, it displays green. When the road accessibility is abnormal, that is, when the road is in a collapsed state, the road accessibility is displayed in red. The remote monitoring screen is set at the road supervision departments at all levels, and the road management personnel can implement administrative measures to temporarily control the road or bridge. The remote mobile phone warning includes pop-up notifications and voice warnings. The data upload here relies on the host computer Internet of Things card. When the host computer detects the lithium battery power warning and road accessibility warning information, it uploads the warning information to the cloud server database. The cloud server data The database transmits the above two types of warning information to the remote monitoring screen and remote mobile phone warning in real time; the voice warning can display the lithium battery power status and road access status on the screen in real time. When the lithium battery power status is normal, it will be displayed in green. When the lithium battery power is lower than 20%, the lithium battery power status will be displayed in red; when the road access status is normal, it will be displayed in green. When the road access status is abnormal, that is, when the road is in a collapsed state, the road access status will be displayed in red; the remote mobile phone warning software is installed at the personnel of road supervision departments at all levels, so that when danger occurs, road management personnel can implement administrative measures to temporarily control roads or bridges.

[0026] When the utility model is in use: the host computer continuously sends instructions through the COM2 serial port. When the bridge or road is in a normal state, the data is transmitted back to the host computer program through the optical terminal B receiving end. The host computer program can parse the receiving end data. The optical cable transmits the data at the receiving end normally, that is, the road is normal, no collapsed specimen has occurred, the relay does not operate, the local circuit breaker alarm does not operate, and the remote monitoring large screen warning and the remote mobile phone warning display in the early warning module are normal; the host computer determines whether the bridge has collapsed by the on-off of the optical fiber. When the bridge or road is in a collapsed state, the optical fiber pre-buried in the bridge or road is pulled off. , the optical terminal transmitter and receiver cannot communicate normally, that is, the transmitter at end A of the optical terminal can transmit data normally, but the receiver at end B of the optical terminal cannot receive data. The host computer program can parse that the COM3 serial port has no received data. At this time, the data acquisition and processing module determines that the bridge or road is in an abnormal state, that is, a collapsed state. At this time, the host computer program sends a command to the relay through the COM4 serial port, and the relay state changes from open to closed. The circuit breaker alarm connected to the relay issues a high-decibel voice reminder, reminding that "the road ahead has collapsed, please pay attention to the passing vehicles." The driver receives the early warning prompt and slows down to avoid danger.
