Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the following examples are illustrative, not restrictive, and the protection scope of the present invention cannot be limited by the following examples.
[0039] A method for optimizing the equipment and personnel configuration of CNG refueling substations based on data mining of refueling records, the process is as follows figure 1 As shown, it specifically includes the following steps:
[0040] 1. Data preprocessing
[0041] By writing a program in Python, load the original gas filling records of a CNG gas filling substation in Tianjin shown in Table 1 into the mongoDB database system, laying the foundation for further analysis; mongoDB database is a typical non-relational open source database, which can take into account different Historical data in record format can also be used for free to reduce costs;

The invention discloses a CNG gas filling substation apparatus based on gas filling record data mining and a personnel configuration optimization method. The method optimizes the CNG gas filling substation device and the human resource configuration system by preprocessing the data, analyzing the gas filling behaviors of the CNG gas filling substation in long and short periods, and counting and analyzing the accumulated gas filling frequency and the gas filling amount. Through the combination with the data statistics and analysis, whether the use of the gas filling guns is in an equalization state can be quantitatively determined; the gas filling behavior fitting curve in the corresponding time interval is obtained by means of the ridge regression method, and the fitting value is given, the quantitative foundation is laid for the balanced optimal allocation of human resources and the gas filling guns, a preliminary method is provided for optimization and the feasibility analysis is carried out; the accumulated gas filling frequency and the gas filling amount are counted and analyzed, the dispatching of transport trucks is optimized and the gas filling efficiency is improved, the gas filling work personnel in the non-gas-filling peak hours is reduced and the CNG gas filling substation operating cost is reduced.
Description
technical field [0001] The invention relates to a CNG refueling substation equipment and personnel allocation optimization method based on gas refilling record data mining. Background technique [0002] Compressed natural gas (CNG) is natural gas that has been compressed (20-25MPa) and stored in high-pressure cylinders. It is loved by users because of its obvious price advantage compared with gasoline and diesel, and it is also strongly recommended by government departments because of its environmental protection advantages. CNG refueling sub-station is the main mode of building stations in China, and its gas source is provided by the parent station near the city through the transfer vehicle. [0003] In recent years, my country's vehicle natural gas has developed rapidly. According to the relevant information provided by China Natural Gas Vehicle Magazine, by the end of 2015, the number of natural gas vehicles in my country had reached 5.03 million (including 4.8 million ...
