Oil exploration wells are scattered and numerous. Most importantly, if there is an abnormal phenomenon, it needs to be dealt with in time. However, wired transmission has many disadvantages, such as high cost, and no mobile network coverage on site. So, there is a need for a wireless transmission technology that supports a large number of wide coverage, efficient data transmission, and a data center that can summarize data for data collection, and then connect the network at the center to synchronize the data to the platform server for related data push and display. Тестовые наборыWorking PrincipleA dormant terminal device is installed on each wellhead and connected with the three-axis sensor at the wellhead as an alarm node to monitor the status of each wellhead. And arrange the router terminal equipment and gateway equipment in the appropriate place to complete the construction of the entire data network:When the three-axis sensor at the wellhead detects the abnormality of the wellhead state, the three-axis sensor sends the abnormal data to the corresponding dormant terminal equipment.The dormant terminal will wake up itself at the first time and report the received abnormal data together with the node ID, latitude and longitude coordinates of the wellhead.The data is received and forwarded to the gateway device through router devices at all levels.After receiving the data, the gateway device transmits the data to the platform server through the 4G network, and the platform server performs alarm push and data presentation.System CompositionThe entire data network consists of dormant terminal equipment, router terminal equipment, and gateway equipment.According to the actual distribution of monitoring points and the coverage of equipment ZigBee signals, it is divided into monitoring areas, and each monitoring point is installed with a dormant terminal device to monitor the monitoring points.In addition, a router terminal device is installed in each monitoring area, and the router terminal device performs network management and data forwarding on the dormant terminal devices in the entire area and selects a power supply, signal, and on-site environment in the entire on-site environment. A coordinator terminal is installed on a good site to ensure the work of the entire network.In the entire ZigBee network coverage environment, you can find a site with 4G network signal coverage, and install a gateway there. The gateway joins the entire ZigBee network as a router and conducts data with the entire ZigBee network. interact and synchronize related data to the Internet.If there is no 4G network signal coverage site in the ZigBee network coverage environment, the network coverage can be extended by cascading router terminal equipment until the gateway is installed in the 4G network signal coverage area.System AdvantageExcellent low power consumption performance: All exploration points are reported by dormant nodes, and can be powered by batteries. Only routing and gateways need a continuous power supply.Strong network self-healing: Using ZigBee self-organizing network technology, if the equipment is damaged, the equipment can be removed from the network and replaced by spare equipment, which will not affect the work of other nodes, and the system has good stability.Беспроводной модемNo need for network coverage: The entire data network operates independently, only the gateway needs to be installed in the area with network coverage, and other devices do not need network support, which is suitable for remote areas with no network or poor network status.
