Reading data from the HDAPS sensor is a straightforward process requiring an open and close of the file at each read due to its nonseekable nature.

注意：由于 Design Data 工具和 Design 工具使用同一个文件，因此最好在关闭一个工具之后再打开另一个工具。

Note: Since the Design Data tool and the Design tool use the same file, it's a good practice to close one tool before opening the other.

在继续之前，先关闭您的mongrel和PostgreSQL实例，这只是为了确保任何打开的文件都得到正确处理。

Before proceeding, shut down your mongrel and PostgreSQL instances, just to make sure any open files are handled correctly.
