lhcsmapi 1.1.31

大型强子对撞机信号监测api包

这是一个带有api的包，用于lhc信号监测项目的信号访问和处理。

先决条件

为了使用api，必须将python包安装程序安装为

pipinstall--userlhcsmapi

在https://pypi.org/project/lhcsmapi/查看最新版本

api依赖于必须以类似方式安装的外部python包。软件包列表存储在<；u>；requirements.txt<；/u>；文件中。

api的文档存储在http://cern.ch/lhc-sm-api。下面是代码结构的摘录和最常用函数的片段。

时间

时间类封装提供了一组用于在各种时间格式之间转换的方法。此外，它还为给定时段之间的天数提供生成器。主要方法有：

• time.convertToUnix时间戳（输入，单位='ns'）
• time.converttostring（输入，单位='ns'）
• time.convertToDateTime（输入，单位='ns'）
• time.converttopandastimestamp（输入，单位='ns'）

• time.daterange（开始日期，结束日期）

fromlhcsmapi.TimeimportTimefromdatetimeimportdatestartDate=date(2014,1,1)endDate=date(2014,1,3)forsingleDateinTime.daterange(startDate,endDate):print(singleDate)>>>2014-01-01>>>2014-01-02

fromdatetimeimportdatestartDate=date(2014,1,5)endDate=date(2014,1,3)forsingleDateinTime.daterange(startDate,endDate):print(singleDate)>>>

元数据

元数据类存储有关信号和电路名称的信息。
