From 8a48074ad44e06e4874faf17e547d48624e2a617 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Peter=20Babi=C4=8D?= Date: Tue, 19 Apr 2016 12:07:51 +0200 Subject: [PATCH] Replace the schematic block with more precise one The previous client schematic block diagram was created in LibreOffice Draw and wasn't detailed/exact/precise enough. This one is created in DipTrace Scematic to provide access to the scientific symbols. --- analytical.tex | 8 ++++++-- figures/relaxcas.pdf | 3 --- figures/schematic_block.dch | 3 +++ figures/schematic_block.jpg | 3 +++ figures/schematic_block.odg | 3 --- figures/schematic_block.pdf | 3 --- figures/tlmosc.pdf | 3 --- tukethesis.pdf | 4 ++-- 8 files changed, 14 insertions(+), 16 deletions(-) delete mode 100644 figures/relaxcas.pdf create mode 100644 figures/schematic_block.dch create mode 100644 figures/schematic_block.jpg delete mode 100644 figures/schematic_block.odg delete mode 100644 figures/schematic_block.pdf delete mode 100644 figures/tlmosc.pdf diff --git a/analytical.tex b/analytical.tex index b00f18c..6f667ea 100644 --- a/analytical.tex +++ b/analytical.tex @@ -85,14 +85,18 @@ The measuring devices, from now on called \textbf{client nodes}, will consist of \subsection{Hardware components breakdown} For the \textbf{server node}, a complete working solution already exists, ready to be employed.

The actual ESP-12E module should be used, because of the available certification\cite{online:2ADUIESP-12}, which allows it to be introduced on the market later. It was shown in the figure \ref{f:esp-12e}. The \gls{pwm} is present there too, so sound indication requires just an additional sound emitting device. Talking about the measurement circuitry, the viable candidate is MAX78615 \cite{online:MAX78615} with the companion \gls{ic} MAX78700 \cite{online:MAX78700}. The couple \ref{f:schem_block} should be used, because it provides multiple ways of same voltage level communication with the processor, galvanic isolation via the pulse transformer for improved circuitry protection, great precision, accuracy and utility.

The circuit protection against high voltage should be solved with an isolated DC-to-DC converter\cite{carr1996linear} or with the linear transformer coupled with the linear voltage regulator\cite{2008linear}. Since the former one is either expensive or hard to design, the choice should fall on the latter. diff --git a/figures/relaxcas.pdf b/figures/relaxcas.pdf deleted file mode 100644 index c64397e..0000000 --- a/figures/relaxcas.pdf +++ /dev/null @@ -1,3 +0,0 @@ -version https://git-lfs.github.com/spec/v1 -oid sha256:c676b427ddca7c35f922b3c2931e018193eb94489872d409e804237052e1df71 -size 2881 diff --git a/figures/schematic_block.dch b/figures/schematic_block.dch new file mode 100644 index 0000000..d6e3d0f --- /dev/null +++ b/figures/schematic_block.dch @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:9eaeab8c700e27b864c9247585a2358ef931df5c42143ab168bcb828df31d814 +size 60366 diff --git a/figures/schematic_block.jpg b/figures/schematic_block.jpg new file mode 100644 index 0000000..39d36be --- /dev/null +++ b/figures/schematic_block.jpg @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:9f8ca80df2ad5348872230f5c003798228cfe86d7f4d1752709e10a0e14b27b8 +size 243976 diff --git a/figures/schematic_block.odg b/figures/schematic_block.odg deleted file mode 100644 index 4c48889..0000000 --- a/figures/schematic_block.odg +++ /dev/null @@ -1,3 +0,0 @@ -version https://git-lfs.github.com/spec/v1 -oid sha256:767bd03102ea7f5c08541f5bcac9391b5116db8c91133588936aec9d812c8574 -size 15737 diff --git a/figures/schematic_block.pdf b/figures/schematic_block.pdf deleted file mode 100644 index 1d1fb23..0000000 --- a/figures/schematic_block.pdf +++ /dev/null @@ -1,3 +0,0 @@ -version https://git-lfs.github.com/spec/v1 -oid sha256:9fc5364222e36960d83c02a202563d701e560c819b22a34f24aa52ee302068e7 -size 27949 diff --git a/figures/tlmosc.pdf b/figures/tlmosc.pdf deleted file mode 100644 index cfc89c4..0000000 --- a/figures/tlmosc.pdf +++ /dev/null @@ -1,3 +0,0 @@ -version https://git-lfs.github.com/spec/v1 -oid sha256:201028e3e66484764ccd369a81a633a79f64aca60d93e80e215460722d81e9d4 -size 4940 diff --git a/tukethesis.pdf b/tukethesis.pdf index c8024ec..618be0d 100644 --- a/tukethesis.pdf +++ b/tukethesis.pdf @@ -1,3 +1,3 @@ version https://git-lfs.github.com/spec/v1 -oid sha256:819544f8ae2cf5c03b68e65097c1c5009c39f10b57b8130bb84089ccc001d7d1 -size 2462392 +oid sha256:00d2cf5d2a4bfb34f96c576f43191c61e3c965d3ab5e0e0b4c764e0b783ad9c8 +size 2681577
