Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. The product represented by this dataset is a smart electricity meter, which is an electricity meter with functions such as electrical energy metering, information storage and processing, real-time monitoring, automatic control and information interaction, with a single-unit weight of about 0.82 kg, mainly composed of a measurement unit, a data processing unit, a communication unit and electronic components such as resistors and capacitors, circuit boards and lithium batteries, etc., made through processes such as SMT soldering, DIP soldering and assembly testing. The key upstream raw materials of this product are electronic components such as resistors and capacitors, circuit boards and lithium batteries, etc., and downstream it is mainly applied in data acquisition of smart distribution networks and smart grid management. In terms of system boundary, infrastructure such as the manufacture of production equipment and the construction of plant buildings is not included within the dataset boundary. In terms of data sources and data processing, the data inventory is formed by merging data from multiple sources, and electricity and other energy are calculated using the Chinese average energy structure.
Activity Description
The system boundary for the smart electricity meter is set from cradle to gate, with the starting point being the input of raw materials and the end point being the dispatch of the finished smart electricity meter from the plant. The primary stages, in sequential order, comprise SMT soldering (e.g., resistors and capacitors), DIP soldering (e.g., semi-finished PCBs and other electronic components), and assembly and testing (e.g., lithium batteries).
Process Description
A smart electric energy meter is composed of a measurement unit, a data processing unit, a communication unit, etc. It has functions such as electric energy measurement, information storage and processing, real-time monitoring, automatic control, and information interaction. It is one of the basic equipment for smart grid data collection. It undertakes the tasks of original electric energy data collection, measurement, and transmission, and is the basis for information integration, analysis, optimization, and information display. Smart energy meters are mainly composed of measurement units, data processing units, communication units and electronic components (resistors, capacitors, etc.), circuit boards, lithium batteries, etc. In addition to the basic power consumption measurement functions of traditional energy meters, they also have intelligent functions such as two-way multiple rate measurement, user-side control, two-way data communication with multiple data transmission modes, and anti-electricity theft. They are in the form of table-mounted or wall-mounted energy meters and are widely used in intelligent distribution network data collection and smart grid management.

Technology comment
The production of smart energy meters mainly includes SMT welding, DIP welding and assembly testing. SMT welding is a method of directly installing electronic components on the surface of a printed circuit board; DIP welding is a process that uses pump pressure to form a solder wave of a specific shape on the surface of the molten liquid solder. When the assembly with the components inserted passes the solder wave at a fixed angle, a solder joint is formed in the pin soldering area; after passing the assembly test (including lithium batteries, etc.), the finished smart energy meter is made.
