When you mention Guangqi Honda, what immediately comes to mind？The Honda Accord is definitely on consumers' minds。But what practitioners think of is its lean manufacturing capabilities。

But you know what？Guangqi Honda, which is famous for lean management, has an air compressor station equipped with international first-line brand equipment, which can actually save energy by 2.42 million KWH per year?How is this done?Only from the central air compressor station, it can save 1.06 million KWH of electricity a year, which is converted into 820,000 yuan of electricity。

Through statistical analysis of energy consumption, Guangqi Honda found that the electricity consumption of air compressor system accounted for 13% of the whole plant, and it was the largest energy consumption in the plant。Although the equipment is all energy efficient equipment, equipment operation and maintenance management, operation is well organized, but this does not mean that there is no energy saving space to explore。

2021, the first cooperation, small test

No. 1 screw machine air compressor station has completed the digital intelligent transformation, becoming the first air compressor station in the automotive industry to achieve fully intelligent operation。Using AI+IoT technology, the cloud + edge + end AI cloud intelligent control system built can intelligently predict the pressure change law of the pipe network, intelligently control the operation of equipment, improve the management efficiency of station buildings, and reduce energy waste。After the intelligent transformation of No. 1 air compressor station, it saves 1.36 million KWH of electricity per year, equivalent to 1.04 million yuan of electricity, and reduces carbon emissions by 612 tons。

In 2022, energy conservation will be carried out to the end

Further explore the energy saving and carbon reduction space, and carry out the energy saving and carbon reduction of air compressor station to the end。

There are three goals for the intelligent transformation of No. 2 centrifuge station:

1.The 5 equipment (4 centrifuges, 1 screw machine) in the No. 2 centrifuge station are all connected to the AI cloud intelligent control system to realize the linkage control of No. 1 and No. 2 air pressure。

2.Solve the problem of poor coordination control between screw machine and centrifuge before。

3.Further improve the energy efficiency of the air compressor station of Guangqi Honda Zengcheng Plant, and tap the potential of energy saving and carbon reduction of the air compressor station。

After the AI Cloud intelligent control came online in the No. 2 centrifuge air compressor station, the changes were reflected in two aspects:

Energy efficiency model of single centrifuge

AI cloud intelligent control calculates the true energy efficiency level of each equipment, giving priority to the operation of more energy-efficient equipment to achieve energy saving and carbon reduction。

Gas production efficiency model of whole station

AI cloud intelligent control unifies the two scattered stations No. 1 and No. 2 into a whole from the data, establishes the gas production efficiency model of the whole station, makes the screw machine and centrifuge operate in coordination, and optimizes the whole situation, realizing the efficient cooperative gas supply between the two stations and the optimal energy efficiency。

This further Narrows the main pressure band, making the entire compressed air system more stable, efficient, and energy efficient。

After the completion of the number of intelligent transformation of the No. 2 centrifuge station room, the energy saving effect of the air compressor station room of Guangqi Honda Zengcheng Plant has reached a higher level, saving more than 1.06 million degrees of electricity per year, equivalent to 820,000 yuan of electricity, and reducing carbon emissions by 447 tons。

The No. 1 and No. 2 air compressor stations save 2.42 million KWH of electricity and reduce carbon emissions by 1,089 tons per year。

In the future, Guangqi Honda will focus on the main line of data intelligence and energy saving and carbon reduction, and build the air compressor station into a first-level energy efficiency air compressor station, and dig each energy saving and carbon reduction link to achieve the company's goal of energy saving and carbon reduction。There is no upper limit to energy saving, energy saving in air compressor stations is a link of lean production, Guangqi Honda is still promoting more energy-saving projects, and continue to polish Guangqi Honda's "lean manufacturing" this shining golden sign。
