In order to solve the above problems, the present application provides a traffic operation and maintenance management system, which uses Long Range Radio (LoRa) low power consumption wide coverage technology to apply to intelligent operation and maintenance of traffic tunnels and traffic platform key points, so as to replace the existing wired network or NB-IoT scheme in the market, and also uses a double link redundancy scheme to ensure that monitoring data is reliably transmitted to a management center.

The traffic maintenance management system 100 is described below in connection with specific embodiments.

Fig. 1 shows a schematic structural diagram of a traffic operation management system 100 according to an embodiment of the present application. The traffic operation management system 100 includes a plurality of terminal acquisition modules 110, a redundancy communication module 120 and a management center module 130, wherein the redundancy communication module 120 is respectively connected to each terminal acquisition module 110 and the management center module 130 to receive the monitoring data acquired by each terminal acquisition module 110 and send the monitoring data to the management center module 130.

Each terminal acquisition module 110 is used for acquiring the operation state and the operation environment of traffic facility equipment, and acquiring monitoring data, wherein the traffic facility equipment comprises urban rail traffic stations, traffic tunnel equipment and facilities.

In one embodiment, as shown in fig. 2, each terminal acquisition module 110 includes a LoRa node unit 111 and a plurality of sensor units 112, each sensor unit 112 is configured to acquire different types of monitoring data, and the LoRa node unit 111 is configured to send the acquired monitoring data to the redundant communication module 120 through a LoRa wireless link.

In a specific deployment, the LoRa node unit 111 may be interconnected with the plurality of sensor units 112 by adopting a serial interface Modbus, a two-wire serial communication interface I2C, an asynchronous serial communication interface UART, a full duplex communication bus interface SPI and the like, and may be deeply fused with the sensor units 112 by adopting the LoRa node unit 111, and the terminal acquisition module 110 may be directly integrated, so that the installation is easy and the deployment may be fast. Or a plurality of data streams are transmitted on a single loRa node unit 111 in a mode that the single loRa node unit 111 is connected with a plurality of sensor units 112, so that centralized collection and transmission of monitoring data in the urban traffic system are realized, the equipment cost and maintenance cost are reduced, and the monitoring integrity is improved.

The redundant communication module 120 is used for detecting whether each communication link is faulty, and the collected monitoring data is sent to the management center module 130 based on the communication link that works normally.

In one embodiment, the redundant communication module 120 includes a relay unit 121 and a base station unit 122, where the relay unit 121 is configured to receive the monitoring data through a preset communication frequency point, where the preset communication frequency point is a frequency interval allocated to a specific communication service in the radio spectrum, and each relay unit 121 operates on a predetermined communication frequency point to avoid mutual interference and ensure clarity and efficiency of communication. The relay unit 121 forwards the monitoring data to the base station unit 122 through a communication link that works normally, and the monitoring data can be uploaded to the relay unit 121 at the nearest distance, and the relay unit 121 is used for enhancing the coverage of traffic operation and maintenance management in the long and narrow tunnel and station environment and reducing the influence of signal attenuation. The base station unit 122 is configured to transmit the monitoring data to the management center module 130 via a communication link that is operating properly. The base station unit 122 may achieve a larger coverage area than the relay unit 121, may be deployed in a traffic station or a communication room/control room on the station side, and receives the data stream of the relay unit 121. The base station unit 122 further uplinks the monitoring data to a communication network server and an upper computer of the traffic operation management center through a communication link, if the urban traffic system adopts a cloud architecture, the base station unit 122 can also uplinks the data directly to a cloud platform, and a more comprehensive analysis and prediction report can be generated through integrating a big data analysis platform so as to support long-term operation optimization of the traffic system and ensure that key monitoring data is not lost.

Alternatively, the relay unit 121 may be a LoRa gateway/route to extend the coverage area of the LoRa network, and the base station unit 122 may be a LoRa base station, it being understood that the LoRa gateway/route typically operates between the terminal acquisition module 110 and the LoRa base station, is battery powered, and may be installed anywhere, without requiring power or internet connections, which makes the traffic maintenance management system 100 an easy-to-deploy, low-cost and low-power network coverage extension.

In one embodiment, the communication link includes a master communication link and a slave communication link, the redundant communication module 120 is further configured to forward the monitoring data through the master communication link when the master communication link is normal, the redundant communication module 120 is further configured to forward the monitoring data through the slave communication link when the master communication link is detected to be faulty, and to forward the monitoring data through the master communication link again when the master communication link is detected to be restored to normal.

In one embodiment, when the LoRa gateway/router and LoRa base station detect a primary communication link connection interruption or abnormal condition (such as link disconnection, network jitter, etc.), the network will automatically switch to a standby secondary communication link, ensuring that the transmission of the monitoring data is not interrupted. The handoff procedure between the master and slave communication links is seamless and the LoRa gateway/route and LoRa base station will automatically complete the handoff in a short period of time. Once the master communication link returns to normal, the LoRa gateway/route and LoRa base station automatically switch back to the master communication link and cease using the slave communication link.

In the application, a plurality of factors need to be considered in selecting a proper communication technology in a special environment such as a traffic tunnel, including coverage, power consumption, data transmission rate, network deployment cost and the like. The LoRa technology can be applied to the aspect of tunnel security operation by the characteristics of long-distance communication capability and high flexible deployment. Meanwhile, because of different areas of the traffic platform and complex building environments, the LoRa technology can also be widely applied to intelligent operation and maintenance of the traffic platform side, including environment monitoring and control, equipment health monitoring illumination and temperature control management, personnel flow monitoring and safety management. The number of nodes of the LoRa network can reach tens of thousands or even millions, one LoRa gateway/route can be connected with a plurality of nodes or terminal equipment to realize point-to-multipoint communication, and the low-power consumption design ensures that the service life of the LoRa battery can reach 3-10 years. The LoRa protocol is simpler than NB-IoT, easier to develop and better suited and compatible for microprocessors for the terminal acquisition module 110.

Optionally, the main communication link is ethernet communication, and the slave communication link is cellular network communication, because ethernet communication has high bandwidth, low delay, high stability, and low data transmission cost, and is hung on the own network in the urban traffic system, no extra operation cost is required, and the characteristics of not occupying the bandwidth resources of the cellular network in traffic, etc., the relay unit 121 and the base station unit 122 monitor the uplink data preferentially through ethernet communication. Because the relay unit 121 and the base station unit 122 can also configure cellular network communication (such as 4G LTE/5G), the existing LTE network in the urban traffic system can be directly used to establish cellular link connection, and by sharing the existing network facilities, additional hardware construction cost can be saved.

In an embodiment, the terminal acquisition module 110 and the redundant communication module 120 are further configured to use unlicensed frequency bands for communication. It is appreciated that wireless LoRa is low cost, easy to expand, and uses unlicensed bands for LoRa communications compared to NB-IoT, e.g., the unlicensed bands where LoRa operates below 1GHz, without additional payment, which helps reduce long-term operating costs.

The database server is used for storing, managing and maintaining the monitoring data, including the operations of inserting, updating, deleting and the like, and is also used for carrying out index construction of the monitoring data so as to improve the query efficiency of the monitoring data, and is also used for carrying out the aggregation operation of the monitoring data and summarizing and analyzing the scattered monitoring data. The database server is also used to provide interfaces for other applications so that these applications can access and manipulate the monitoring data in the database. The SCADA server is used for judging whether the urban traffic system is in a normal running state according to a preset rule, and is also used for providing interfaces for other systems (such as the operation unit 132 and the visualization unit 133) to acquire equipment state data or send control instructions.
