Safety system at a discharge port in a pool |
摘要 |
<p>In a swimming pool in which water is circulated by a pump, a schoolboy child is liable to be absorbed into a discharge port, which is dangerous. A sensor which has a load cell is provided at the back of a water-permeable cover in the discharge port. If a human body of the child is absorbed into the discharge port and contacted with the cover, the load cell is pressed by the water-permeable cover to transmit a signal to a control circuit in which it is determined whether or not pressure variation applied to the sensor is normal or abnormal. If abnormality is determined therein, an alarm is sounded to inform a watcher of the accident and the pump is stopped to release the child from the discharge port. <IMAGE></p> |
