HAOROP7o){ <br />System Operations <br />The SmartCovero system works by taking a distance measurement every 6 minutes <br />using the DSM (ultrasonic sensor). If the water is below the alarm level, the <br />SmartCovere logs every other distance reading and sends it to the historical server <br />every hour for long term trending. If the water level is above the alarm level, an <br />alarm notification is sent directly to the users. It is a 24 hour a day, 7 day a week <br />system. <br />Below is a typical graph from the City of Santa Ana secure web page. It can be <br />seen that everything is normal and then there is a high water level alarm. The <br />bottom of the sensor is 64 inches from the manhole cover and the alarm is set for 74 <br />inches below the manhole cover. <br />The City of Santa Ana will receive alarms through cell phone or pagers via Short <br />Message Service (SMS), or Smart Phones and emails via email messaging. A <br />direct - from - satellite handheld system is available upon request for highly critical <br />communications in case of massive power loss upon request. <br />A LEVEL MEASUREMENT IS TAKEN EVERY 6 MINUTES AND UPDATES THE <br />DATA ON THE SERVER EVERY HOUR. IN THE EVENT OF A HIGH WATER <br />EVENT, THE ALARM IS SENT THE NEXT TIME A LEVEL MEASUREMENT IS <br />MADE. IN THIS CASE THE LONGEST TIME BETWEEN THE TIME THE WATER <br />REACHES THE ALARM LEVEL AND WHEN THE ALARM SOUNDS IS 5 <br />MINUTES AND 59 SECONDS. <br />11 <br />lladronex Inc. 381 Engel Street, Escondido, CA, 92026 <br />2012.05.04 13.56 - 2012-05-12 13;56 Distance from Manhole Cover <br />Alarm Setpoint = 74 <br />Sensor <br />Positlon = 64 <br />60 in <br />65 in <br />..,....,, <br />............ <br />......... <br />............ <br />.. ............ <br />... <br />......... <br />,...,..., <br />70 in <br />75 in <br />80 in <br />85 in <br />90 in <br />45 in <br />....c....w..w..c..w.,�.i.�.. <br />. <br />°o <br />o <br />o <br />°o <br />u <br />5a <br />4R <br />iV <br />N <br />PY <br />N N N <br />!+i <br />N <br />N <br />N <br />iV <br />N <br />N <br />N <br />N <br />f*d <br />N <br />N <br />tA <br />H <br />M <br />r <br />O <br />kA <br />O <br />u% <br />A <br />th <br />A <br />O <br />C b <br />t <br />*A <br />OA <br />© <br />O <br />9 <br />O <br />The City of Santa Ana will receive alarms through cell phone or pagers via Short <br />Message Service (SMS), or Smart Phones and emails via email messaging.
