<h1> Popis konstrukce </h1> |
|
| 95 |
|
|
| 96 |
<h2> Důvod vzniku </h2> |
|
| 97 |
|
|
| 98 |
<p> |
|
| 99 |
Tento zapisovač byl vyvinut během Fyzikálního Týdne na FJFI ČVUT v Praze. Za účelem použití v miniprojektu Stanovení radiační zátěže od kosmického záření na palubě letadla. |
|
| 100 |
</p> |
|
| 101 |
|
|
| 102 |
<p> |
|
| 103 |
Zařízení je z části postaveno z modulů stavebnice (kromě Palmtopu, do kterého se ukládají data a samotného detektoru radiace.) Celý zapisovač funguje vlastně jako komprimátor dvou datových toků, jednak z GPS geko 201 a potom ze scintilačního detektoru NB 3201 a případně z intezimetru IT-65. |
|
| 104 |
</p> |
|
| 105 |
|
|
| 106 |
|
|
| 107 |
<h2> Zapojení modulů zapisovače </h2> |
|
| 108 |
|
|
| 109 |
<p> |
|
| 110 |
<img src="../../SCH/GPSRL.png" width="680" height="271"> |

</p> |
|
| 112 |
<p> |
|
| 113 |
Modul PIC16F84SO1801A je osazen procesorem PIC16F88, protože je potřeba A/D převodník pro zpracování logaritmického analogového signálu ze scintilátoru NB 3201. Připojení intenzimetru IT-65 je provedeno tak, že pulsy se z konektoru přivádí přímo na komparátor v procesoru a z něj do čítače odkud se programově čtou. |

<h2> Program </h2> |
|
| 122 |
|
|
| 123 |
<p> |
|
| 124 |
Původní zdrojový kód od celého zařízení se mi někam záhadně ztratil Doufám, že ho ale ještě někde objevím, protože i přes jeho jednoduchost byl docela pracný. |
|
| 125 |
</p> |
|
| 126 |
<p>Program pracoval tak, že periodicky četl textový výstup z GPS přijímače a do něj doplňoval naměřenou hodnotu z čítače, nebo A/D převodníku.</p> |
|
| 127 |
<p> |
|
| 128 |
Výsledný datový soubor ukládaný v palmtopu pak vypadal takto: <br> |
|
| 129 |
