- In the course of design , we fully consider the actual conditions on the railway and take a series of corresponding measures to the concrete problem . such as we select high - accuracy microconvertor and have the converted function in succession data collecting system chip aduc812 , design v / f circuit and external a / d circuit . in anti - interference of the hardware , we try to disperse each function module to avoid interfering each other , adopt photoelectric isolated technology to dispel the circuit connection of input and output . in controlling we import arithmetic mean into strain wave algorithm and real computing technology of virtual value for sample treatment of data , that is using the software to smooth away interfere error and to calculate actual value , thus it makes the precision of the data improve greatly
在设计过程中，根据系统要求，充分考虑铁路上的实际情况，针对具体问题采取了一系列的相应措施，如在器件选择方面选用高精度microconvertor系列、具有adcdma连续转换功能的数据采集微控制器芯片aduc812 ，设计了v f变换电路和外部a d转换电路；在硬件抗干扰方面，将每个功能模块尽量分散独立开来以避免相互干扰、采用光电隔离技术消除输入输出通道上的电路联系；在控制方面对于采样数据的处理引入了算术平均值滤波算法和真有效值的计算方法，即通过使用软件来滤除系统中有干扰造成的误差并计算真值，从而使数据的准确性得到极大地提高。 - The comprehensive ranking of a site or entity depends on the arithmetic mean value of the following parameters : visit rate , average number of days a cyber user visits the site or entity , non - repetitive pages opened and total number of pages opened , average time and number of times a cyber user visits the site or entity
某网站或实体的整体排名是由以下指标的算术平均值决定的：到达率平均每个网民访问该网站或实体的天数打开的不重复页面和整体页面展开数平均每个网民访问该网站或实体的时间和访问次数。
英文释义
名词- the sum of the values of a random variable divided by the number of values
同义词：first moment, expectation, expected value
百科释义
In mathematics and statistics, the arithmetic mean, or simply the mean or average when the context is clear, is the central tendency of a collection of numbers taken as the sum of the numbers divided by the size of the collection. The collection is often the sample space of an experiment.
