Synchronous timing module, which adopts the satellite clock timing scheme based on digital phase-locked loop to provide stable clock pulse signal for the acquisition unit; data processing module, which is used for receiving the measurement data transmitted by the intelligent acquisition module and preprocessing, constructing The data upstream information model of the unified time section of the acquisition layer and the upper monitoring layer is output, and the preprocessed measurement data of the unified time section is output.

Description

technical field [0001] The invention belongs to the field of data acquisition, and in particular relates to a data acquisition unit, a data transmission method and a comprehensive energy monitoring system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Multi-energy complementary systems are an important way to provide end-users with flexible, energy-saving integrated energy services. Specifically, a multi-energy complementary comprehensive energy system refers to a "regional energy Internet" system that can accommodate a variety of energy resource inputs, and has a variety of output functions and transportation forms. It is not a simple superposition of a variety of energy sources, but a comprehensive and complementary utilization of different energy tastes at the height of the system, and the coordination relationship and conversion bet...

Problems solved by technology

The inventors found that the current data acquisition and monitoring has the problem of multi-energy flow and multi-time scale differences, which cannot guarantee the unity of time sections between the data layer and the upper monitoring layer; GPS timing is easily affected by the environment and interrupted at regular intervals, resulting in synchronization time errors in each acquisition node Problem: The amount of data in the integrated energy system is relatively complicated, and there is a problem of high end-to-end delay of node data packets in the transmission process of the wireless sensor network, which cannot guarantee the real-time validity of the data; the data collection of the integrated energy system involves multi-category For sensors, each node needs to collect different parameters, which does not meet the plug-and-play requirements of each sensor, and thus cannot realize the comprehensive perception of node data
