The invention relates to an industrial signal data access method based on a fixed-length data block and solves the defects of waste of data extraction resources due to low industrial signal source extraction data utilization rate in the prior art. The method comprises the following steps: constructing a memory server cluster; encoding measuring points on each memory server; receiving data sent by a data high-speed bus; carrying out memory server data receiving and processing; and requesting the server or a client to read the data. The method reduces calculation load of the server in data retrieval, and meets requirement for real-time display of process key data of the client and real-time display of an industrial curve report. 本发明涉及基于定长数据块的工业信号数据访问方法，与现有技术相比解决了工业信号源提取的数据利用率低造成数据提取资源浪费的缺陷。本发明包括以下步骤：构建内存服务器集群；对测点在内存服务器上进行编码；接收数据高速总线所发送的数据；内存服务器数据的接收与处理；请求服务器或客户端读取数据。本发明降低了服务器检索数据的计算负荷，满足了客户端的工艺关键数据实时展现以及工业曲线报表的实时展现要求。
