DATA ACQUIRING CARD "RADESD"
|
|
DESCRIPTION
|
|
The Digital accelerometric recorder RADESD, is a development of CIRES, proponed as an available choice to measure the seismic response of structures under the action of earthquakes, useful to evaluate the conditions of structural security. RADESD can use triaxials strong motion recorders of de solid state servo actuated and to take until 200 signs per sec., with a resolution of 12 or 16 bits.
|
|
FUNCTIONING
|
|
It can start its operation when the sign amplitude in any channel reaches the proponed threshold. RADESD equipment has got memory in solid state and an operation program developed in a graphic environment that shows every operation parameter, it also permits to configure the system, its different recording and analyzing ways. It can communicate its information by series 232 port, locally until 115.2 kbauds or by modem with telephonic line. It admits signs of external time of reference and tele control start.

COMPONENTS
|
|
The accelerometric recording system is compound by the following elements:
*Protection board: Metallic board with reference to physic ground.
*Data acquiring card: RADESD card with 12 bits of resolution (16 optional bits).
*Accelerometric Sensors: Triaxial array of de servosensors with range of 1/2 g., aligned with the geographic axis.
*Feeding Batteries: Automotive accumulator of +12 V CD that proportionates the energy necessary to the functioning of the cards and the sensors (It is recommended to use sealed batteries without maintenance).
*Solar Panels: They are located on the top of the cabin, they maintain the charging of the feeding batteries.
*Batteries charger: It gives a cycle of charge or discharge to the equipment battery for it to last more.
