Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, and the exemplary embodiment of the present invention and explanation thereof are only used for explaining the present invention, not as a limitation of the invention.
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment remote terminal control system, including safety zone and explosion-proof area, in safety zone, it is provided with concentrator, in explosion-proof area, is provided with multiple interconnective wireless collection front end and effusion meter；Concentrator, for collecting the measurement data of wireless collection front end outside safe distance, and measurement data uploads teletransmission platform by uploading data module, or data transfer to metering system, Ore-controlling Role of standing is processed in situ by local port；Wireless collection front end, for gathering the measurement data of effusion meter and by being wirelessly transmitted to concentrator；Effusion meter, for detecting the gas flow in natural gas line.
Described wireless collection front end includes following:
Communication module, docks with intelligent flow meter, for by data on flows transmission to MCU；
MCU, is used for regulating and controlling all of module, and receives the data message that communication module is transmitted, and integrate this data message；
LORA wireless module, the transmission on a large scale of the data on flows after integrating；
Power supply, is used for providing stable operating voltage；
DC/DC changer, for conversion electric power output voltage with mate intelligent flow meter supply voltage；
Unified expansion interface, unified expansion interface, for extending the connection approach of MCU and external module, including RJ45 interface, strengthen I/O interface and AI interface, and AI interface is connected with combustible gas probe.
Wireless collection front end is as the parts being directly connected to intelligent flow meter, it is responsible for gathering the measurement data of intelligent flow meter, and send it to concentrator, and concentrator can collect the measurement data of wireless collection front end outside safe distance, and measurement data uploads teletransmission platform by uploading data module, or in situ by local port, data transfer to metering system, Ore-controlling Role of standing are processed.And when measurement data teletransmission, upload data module and use GPSR, GPSR is a typical location-based Routing Protocol, use GPSR agreement, network node both knows about self geographical position and by unified addressing, and each node utilizes greedy algorithm as far as possible linearly to forward data, and this agreement avoids to be set up in node, safeguard, stores routing table, only rely on direct neighbors to be routed, almost one stateless agreement；And using the route close to the shortest Euclidean distance, data transmission delay is little；As long as and can guarantee that network connectivty is not destroyed, necessarily it can be found that up to route, improve promptness and accuracy that measurement data transmits.And when measurement data transmits on the spot, by interfaces such as RS485 or RJ45, then can realize measurement data and the most accurately be sent to metering system, Ore-controlling Role of standing.
When carrying out gas discharge data acquisition, using single battery to power, the external electrical network power supply mode of abandoning tradition, to prevent thunderbolt from introducing pulse by external electrical network；And for intelligent flow meter, by DC/DC changer, the magnitude of voltage being delivered to intelligent flow meter making battery raises, to ensure the normal work of intelligent flow meter, gas discharge in pipeline is measured by intelligent flow meter, and by communication module, the data of measurement are sent to MCU, by the integration of MCU, this measurement data is sent to terminal by LORA wireless module, i.e. achieves the remote collection to gas discharge.And unification expansion interface, it is to ensure that collection front end can adapt to new requirement afterwards and is pre-designed, improves the extended capability gathering front end, wherein, unified expansion interface includes RJ45 interface, enhancing I/O interface and spare interface.
