[0043] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] As an important part of the urban transportation system, traffic stations need to involve the management of multiple equipment and facilities; traffic tunnels have always been one of the most important considerations in the entire urban transportation operation and management system because of their narrow and long space, small cross-sectional capacity, low naked eye visibility and complex environment inside the tunnel. At present, urban transportation systems generally use multiple field-level switches and central-level core switches for visual intelligent management and control. The field-level switches complete the access and forwarding of the underlying field terminals. The data information collected by the field terminals is forwarded to the central-level switches. Through the monitoring screen and the intelligent management platform built into the central-level server, the visual intelligent management and control of traffic tunnels and traffic stations is completed. However, the above solution has problems such as high integrated wiring cost, long deployment cycle, poor flexibility and difficulty in later maintenance. The urban transportation system can also use NB-IoT technology to transform on the existing LTE (Long Term Evolution) network, but the overall deployment cost may be high. In addition, the NB-IoT network signal has weak penetration and limited coverage. To solve the above problems, the present application provides a traffic operation and maintenance management system, which adopts long-range radio (LoRa) low-power wide-coverage technology to apply to the intelligent operation and maintenance of key points of traffic tunnels and traffic platforms, to replace the existing wired network or NB-IoT solutions on the market. The traffic operation and maintenance management system also adopts a dual-link redundancy solution to ensure the reliable transmission of monitoring data to the management center.

[0045] The traffic operation and maintenance management system 100 is described below with reference to some specific embodiments.

[0046] Figure 1 A structural schematic diagram of a traffic operation and maintenance management system 100 according to an embodiment of the present application is shown. Exemplarily, the traffic operation and maintenance management system 100 includes a plurality of terminal acquisition modules 110, a redundant communication module 120, and a management center module 130. The redundant communication module 120 is respectively connected to each terminal acquisition module 110 and the management center module 130 to receive monitoring data collected by each terminal acquisition module 110 and send the monitoring data to the management center module 130.

[0047] Exemplarily, each terminal collection module 110 is used to collect the operating status and operating environment of transportation facilities and equipment to obtain monitoring data, wherein the transportation facilities and equipment include equipment and facilities of urban rail transit platforms and transportation tunnels.

[0048] In one embodiment, if Figure 2As shown, each terminal acquisition module 110 includes a LoRa node unit 111 and multiple sensor units 112; each sensor unit 112 is used to collect different types of monitoring data; the LoRa node unit 111 is used to send the collected monitoring data to the redundant communication module 120 via the LoRa wireless link.

[0049] In specific deployment, the LoRa node unit 111 can be interconnected with multiple sensor units 112 using serial interface Modbus, two-wire serial communication interface I2C, asynchronous serial communication interface UART and full-duplex communication bus interface SPI, etc. The LoRa node unit 111 can be deeply integrated with the sensor unit 112, and the terminal acquisition module 110 can be directly integrated, which is easy to install and can be quickly deployed. Alternatively, a single LoRa node unit 111 can be connected to multiple sensor units 112, and multiple data streams can be transmitted on a single LoRa node unit 111 to realize the centralized collection and transmission of monitoring data in the urban transportation system, reduce equipment costs and maintenance costs, and improve monitoring integrity.

[0050] Optionally, the sensor unit 112 includes an environment monitoring sensor, a water monitoring sensor, a structural health monitoring sensor, and an equipment status monitoring sensor, etc. Among them, the environment monitoring sensor includes a temperature sensor, a humidity sensor, a gas sensor, and a particle sensor, etc., the water monitoring sensor includes a water level sensor, a water leakage sensor, and a water immersion sensor, etc., the structural health detection sensor includes a strain sensor, an acceleration sensor, an optical fiber sensor, an acoustic emission sensor, and an image sensor, etc., and the equipment status monitoring sensor includes a vibration sensor, a pressure sensor, a position sensor, and a sound sensor.

[0051] Exemplarily, the redundant communication module 120 is used to detect whether each communication link is faulty, and send the collected monitoring data to the management center module 130 based on the normally working communication link.

[0052] In one embodiment, the redundant communication module 120 includes a relay unit 121 and a base station unit 122; the relay unit 121 is used to receive monitoring data through a preset communication frequency point, wherein the preset communication frequency point refers to the frequency interval allocated to a specific communication service in the radio spectrum, and each relay unit 121 will operate at the predetermined communication frequency point to avoid mutual interference and ensure the clarity and efficiency of communication. The relay unit 121 forwards the monitoring data to the base station unit 122 through a normally working communication link, and the monitoring data can be uploaded to the nearest relay unit 121, which is used to enhance the coverage of traffic operation and maintenance management in narrow tunnels and platform environments, and reduce the impact of signal attenuation. The base station unit 122 is used to send the monitoring data to the management center module 130 through a normally working communication link. The base station unit 122 can achieve a larger coverage range than the relay unit 121, and can be deployed in a traffic platform or a communication room / control room on the platform side to receive the data stream of the relay unit 121. The base station unit 122 then uploads the monitoring data to the communication network server and host computer of the traffic operation management center through a communication link. If the urban transportation system adopts a cloud-based architecture, the base station unit 122 can also upload the data directly to the cloud platform. By integrating the big data analysis platform, more comprehensive analysis and forecasting reports can be generated to support the long-term operation optimization of the transportation system and ensure that key monitoring data is not lost.

[0053] Optionally, the relay unit 121 can be a LoRa gateway / router to expand the coverage of the LoRa network, and the base station unit 122 can be a LoRa base station. It can be understood that the LoRa gateway / router usually works between the terminal acquisition module 110 and the LoRa base station, is powered by a battery, and can be installed anywhere without the need for electricity or Internet connection, which makes the traffic operation and maintenance management system 100 an easy-to-deploy, low-cost and low-power network coverage expansion method.

[0054] In one embodiment, the communication link includes a main communication link and a slave communication link; the redundant communication module 120 is also used to forward the monitoring data through the main communication link when the main communication link is normal; the redundant communication module 120 is also used to forward the monitoring data through the slave communication link when a failure of the main communication link is detected, and to forward the monitoring data through the main communication link again when it is detected that the main communication link has recovered to normal.

[0055] In one embodiment, when the LoRa gateway / router and the LoRa base station detect that the main communication link is disconnected or an abnormal situation occurs (such as link disconnection, network jitter, etc.), they will automatically switch to the backup slave communication link to ensure that the transmission of monitoring data is not interrupted. The switching process between the main communication link and the slave communication link is seamless, and the LoRa gateway / router and the LoRa base station will automatically complete the switching in a short time. Once the main communication link returns to normal, the LoRa gateway / router and the LoRa base station will automatically switch back to the main communication link and stop using the slave communication link.

[0056] In this application, multiple factors need to be considered when choosing a suitable communication technology in a special environment such as a traffic tunnel, including coverage, power consumption, data transmission rate, and network deployment cost. The LoRa technology, with its long-distance communication capability and highly flexible deployment characteristics, can be applied to tunnel safety operations. At the same time, due to the different areas of the traffic platform and the complex building environment, the LoRa technology can also be widely used in intelligent operation and maintenance on the traffic platform side, including: environmental monitoring and control, equipment health monitoring lighting and temperature control management, personnel flow monitoring and safety management. The number of nodes in the LoRa network can reach tens of thousands or even millions. A LoRa gateway / router can connect multiple nodes or terminal devices to achieve point-to-multipoint communication, and the low-power design makes the LoRa battery life up to 3-10 years. For the terminal acquisition module 110, the LoRa protocol is simpler than NB-IoT, easier to develop, and more applicable and compatible with microprocessors.

[0057] Optionally, the main communication link is Ethernet communication, and the secondary communication link is cellular network communication. Since Ethernet communication has high bandwidth, low latency, high stability, and low data transmission cost, and is attached to the internal network of the urban transportation system, no additional operating costs are required, and the bandwidth resources of the cellular network in the transportation are not occupied, the relay unit 121 and the base station unit 122 preferably monitor the data uplink through Ethernet communication. Since the relay unit 121 and the base station unit 122 can also be configured with cellular network communication (such as 4G LTE / 5G), the existing LTE network in the urban transportation system can be directly used to establish a cellular link connection, and by sharing the existing network facilities, the additional hardware construction cost can be avoided.

[0058] In one embodiment, the terminal acquisition module 110 and the redundant communication module 120 are also used to communicate using unlicensed frequency bands. It can be understood that wireless LoRa has low cost and is easy to expand. Compared with NB-IoT, LoRa communication uses unlicensed frequency bands. For example, LoRa works in unlicensed frequency bands below 1 GHz, and no additional fees are required, which helps to reduce long-term operating costs.

[0059] Exemplarily, the management center module 130 is used to store monitoring data, and to perform remote monitoring, early warning, and maintenance management on the equipment and facilities of urban rail transit platforms and traffic tunnels based on the monitoring data.

[0060] In one embodiment, the management center module 130 includes a server unit 131, an operation unit 132, a visualization unit 133 and a network protection unit 134; the server unit 131 is used to store and process monitoring data, and provide an application interface to support automated management; the operation unit 132 is used to adjust the operating status of traffic facilities and equipment and implement preventive maintenance strategies based on monitoring data; the visualization unit 133 is used to integrate and display monitoring data, and perform visual positioning; the network protection unit 134 is used to build a protective barrier and perform network protection for traffic facilities and equipment.

[0061] Optionally, the server unit 131 includes a video surveillance server, a database server and a Supervisory Control And Data Acquisition (SCADA) server. Among them, the video surveillance server supports video compression technology and has high-speed writing capability to ensure the integrity of video surveillance data. The video surveillance server provides an application program interface API to the outside, allowing other software systems to obtain video data or query video analysis results. The database server is used to store, manage and maintain monitoring data, including operations such as inserting, updating, and deleting data. The database server is also used to build an index for monitoring data to improve the query efficiency of monitoring data. The database server is also used to perform aggregation operations on monitoring data and summarize and analyze scattered monitoring data. The database server is also used to provide an interface for other applications so that these applications can access and operate the monitoring data in the database. The SCADA server is used to determine whether the urban transportation system is in a normal operating state according to preset rules. The SCADA server is also used to provide an interface for other systems (such as the operating unit 132 and the visualization unit 133) to obtain device status data or send control instructions.

[0062] In one embodiment, the operation unit 132 is used to implement preventive maintenance strategies based on monitoring data, which involves real-time tracking and analysis of the performance of traffic facilities and equipment. By analyzing the operating parameters and historical maintenance data of traffic facilities and equipment, possible failures of traffic facilities and equipment can be predicted and maintenance measures can be taken before the failure occurs. This can not only reduce the equipment failure rate, but also avoid traffic interruptions caused by sudden equipment failure, thereby improving the overall reliability and safety of the traffic system. Optionally, the operation unit 132 includes an engineer operation station and an emergency handling and dispatching platform. The engineer operation station is used to monitor various equipment and systems in the traffic network to ensure smooth and safe traffic flow. The engineer operation station adjusts the operating status of traffic facilities and equipment based on the monitoring data, which includes but is not limited to the timing of traffic lights, the display content of variable information signs, and the operation of other intelligent traffic management facilities. The emergency handling and dispatching platform is used to monitor traffic conditions in real time. Once an emergency occurs, such as a traffic accident, a natural disaster or a large-scale traffic congestion, the emergency plan is quickly activated and relevant departments and resources are coordinated for effective processing. The emergency handling and dispatching platform integrates functions such as information sharing, rapid evaluation and decision support to improve the speed and efficiency of emergency response.

[0063] In one embodiment, the visualization unit 133 is used to integrate display functions, perform real-time monitoring and early warning, data analysis and decision support, emergency command and dispatch, and public information services. The visualization unit 133 is also used to achieve early warning and emergency response to traffic accidents. When a traffic accident occurs, the visualization unit 133 can quickly locate the accident site through visual positioning, provide accurate information to rescue personnel, and improve rescue efficiency. Optionally, the network protection unit 134 includes an industrial network firewall, which is used to provide complete protection from the border to the terminal, effectively reduce the risk of network intrusion, and prevent security threats from spreading between systems.
