The power monitoring data of the nodes here cannot be transmitted remotely to the power business platform through the public network IoT card, which is prone to power data islands and cannot perform comprehensive data monitoring. In addition, the power monitoring data of the existing power nodes is complex, involving monitoring data on the status of the power facilities themselves and production detection data of the power facilities, etc. Each power node needs to be equipped with dedicated monitoring equipment for comprehensive power data monitoring of the node. The monitoring equipment has poor versatility, and the remote monitoring platform needs to arrange and adjust the monitoring system according to each node, and the monitoring platform has poor adaptability. Summary of the invention

[0003] To solve the above problems, the present invention proposes an electric power data monitoring system based on three-network operators and high-throughput satellite communications, which reserves two sets of hot-swappable interfaces and can select one or both of the public network communications and satellite channel communications of the three-network operators according to the geographical location of the nodes, thereby ensuring the integrity and timeliness of the power node monitoring data transmission; and through the general definition module, it can assist the monitoring equipment to adapt to the power monitoring equipment of each power node, and the power production area business platform can automatically generate the power data type for power node monitoring.

[0004] The electric power data monitoring system based on three network operators and high-throughput satellite communication of the present invention comprises:

[0005] A monitoring controller, wherein the monitoring controller is connected to a temporary storage device; the temporary storage device is used to temporarily store power data after the public network is disconnected, or power data waiting to be packaged;

[0006] A data reading unit, wherein the data reading unit comprises a dip switch connected to a monitoring controller, and the monitoring controller is also communicatively connected to an interface reading module and a wireless networking reading module; the data reading unit is communicatively connected to a data acquisition device of a power node; each dip key of the dip switch corresponds to an interface reading module or a wireless networking reading module; by presetting a priority arrangement rule of each interface reading module and wireless networking reading module in the monitoring controller, when the dip switch is turned, the monitoring controller can obtain which interface reading modules and wireless networking reading modules are selected by reading the dip switch, and the selected interface reading modules and wireless networking reading modules are selected by The priority arrangement rules are used for the subsequent reading priorities of the selected interface reading modules and wireless networking reading modules, so that after the monitoring controller is initialized, it can call the drivers of the selected interface reading modules and wireless networking reading modules to realize the preparation work before data reception; at the same time, the priority arrangement rules of each interface reading module and wireless networking reading module are synchronously implanted in the power production area business platform. When the power production area business platform receives the information of the interface reading module and the wireless networking reading module, it can synchronously arrange the priorities, so that the data objects sent by the monitoring controller and the data objects received by the power production area business platform can be matched;

When the power node is an important power node, Node, the monitoring controller at the node synchronously connects to the ground portable base station and the ka / ku high-throughput satellite portable station. When the signal of the ground portable base station is interrupted, the monitoring controller temporarily stores the data in the temporary storage and tries to send the power data again. If it is still in the signal interruption state, it quickly switches to the ka / ku high-throughput satellite portable station, and transmits the power data in the temporary storage remotely through the ka / ku high-throughput satellite portable station; and performs the ground portable base station signal test at set intervals. When the monitoring controller signal is restored, it quickly switches to the ground portable base station from the ka / ku high-throughput satellite portable station; thereby ensuring the integrity and timeliness of data transmission at key nodes;

After the machine identification code is entered and confirmed, it is automatically transferred to the data reading selection module. If 232 communication module A is selected, it means entering 232 Communication module A, after entering the port of communication module A 232, selects the power data type according to the actual data sent by the power monitoring device connected to the port, such as selecting the bus, and then selects the voltage, system frequency feeder current, active power, reactive power, power factor and electric energy in turn according to the output list and sequence of the power monitoring device. After completing the selection, the definition of communication module A 232 is completed. Then, the monitoring controller collects the port definitions of all interface reading modules and wireless networking reading modules selected by the dip switch, packages the port definition data, and sends it to the power production area business platform through the data transmission unit. The power production area business platform establishes a storage area for each monitoring node, and receives and updates subsequent power monitoring data;

The monitoring controller confirms the interface reading module and the wireless networking reading module that are connected to the data acquisition device according to the coded data, and confirms the priority of reading or accessing each data acquisition device according to the priority of the interface reading module and the wireless networking reading module; then, the machine identification code of the corresponding power node monitoring device is entered through the monitoring device entry module, and after the entry is completed and confirmed, it is automatically transferred to the data reading selection module, and a certain reading interface of the interface reading module and the wireless networking reading module is selected through the data reading selection module, wherein the entry of the reading interface that is not selected by the dial switch is invalid; after entering a certain reading interface of the interface reading module and the wireless networking reading module, then, the power data type is selected through the function selection module, and the power data type is provided by the function definition library.

Then, the machine identification code, interface type and power data type are sent to the power production area business platform through the data transmission unit. The power production area business platform establishes a storage list with the machine identification code, and uses the interface type and power data type as the table header to obtain a monitoring list.
