As shown in fig. 6, the workflow of the remote monitoring server is: and monitoring the network signal of the data acquisition gateway through the MQTT network connection signal and the network communication heartbeat, if the network connection is closed, creating gateway communication fault information and sending the gateway communication fault information to the cloud platform module for display. If the network connection is not closed, the next step is continued. Reading data and judging: and if the data is the fault information data, the data is directly sent to a cloud platform (module) for display. If the data is the data of the shield terminal data source, the data is stored into the MongoDB database in a lasting mode, and the real-time data is cached into the Redis database. The real-time data is the latest data of the shield terminal data source.
The remote monitoring server detects fault information such as whether resources such as memory and storage of the server are exhausted or not and whether the software system operates normally or not by calling a system command return value of the operating system and whether the read-write data of the software system perform fault self-detection normally. Once a fault is found, fault information is immediately presented to the cloud platform module.
The cloud platform module controls and manages the data acquisition gateway: real-time data are obtained from the Redis database for real-time monitoring, and data are obtained from the MongoDB database for data analysis. And transmitting the automatically generated fault message to the cloud platform module through a network, and when data acquisition is interrupted or a data acquisition link fails, pushing the transmitted fault message to a page by the cloud platform module to perform fault alarm and providing position and removal method information of fault generation. The staff can directly get to the position that the trouble produced according to these information and get rid of, save the work and the time of gathering the trouble investigation of link, resume the data acquisition channel fast, greatly improved efficiency, the quality of data acquisition system operation and maintenance, guarantee to the long-range real-time supervision and the management decision of tunnel shield construction.
For example, data interruption, the cloud platform module generates acquisition gateway internet disconnection fault alarm, and a worker can check the fault removal method and steps on line: (1) checking whether the data acquisition gateway is powered normally; (2) Checking whether the data acquisition gateway is loose in an Internet network plug or not; (3) Checking whether the network switch interface connected with the data acquisition gateway is smooth. The method can be used for rapidly checking the fault cause, performing fault elimination and recovering the smoothness of the data acquisition link.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
