# Ziran Gao 20240905 # 智能二次运维项目中，定值计算功能 #-------------2024年9月6日-------------------------------------------------------------------------------------------------------- # 本功能基本逻辑是： # 1：从外部文件中读取定值单和装置基本参数。 # 2：根据要校验哪些定值的合理性，进行相应的计算。 # 3：将不合理的定值进行标注。 # 4：目前的初步代码开发，因为定值单不是从我这里获取，读取也做不了，因此只暂时只做读取基本参数-由基本参数计算理论定值这一部分。 # 5：首先进行对象的开发。分两个类：供电方式与相应装置 #---------2024年9月13日----------------------------------------------------------------------------------------------------------- # 面向对象实现太复杂，回到面向过程 # 主要逻辑是：首先从外界读入供电方式、运行区域和大所还是小所，根据这些信息，运行指定函数，从中excel中读取基础参数，当前分了两个excel基础参数表 # 一个适用于大所，一个适用于小所，每个所中各有6个sheet，适用于6种供电方式。 # 然后对每种供电方式，建立计算公式库，里面有针对6种设备的计算公式合集。 # 对每个定值应该单独写函数计算，为了避免传入函数太多以及我不是所有都要校核。 # 目前仅是定值计算，还没到合理性校验那里。 # encoding:utf-8 #---------2024年10月10日----------------------------------------------------------------------------------------------------------- # 定值计算第一稿完成 # 分为读取，计算，存储三部分。 # 部分计算还存在疑问，但已完成从excel中读取系统参数-程序计算-存储至数据库对应表整个功能历程。 # 对每个装置各建了个表，对馈线建了三个表，分别表示0区1区2区 # 之所以这么做是为了后续只计算某个区的时候方便。 # encoding:utf-8 import pandas as pd import ImportSystemParameter as ISP import
