Title:
MAINTENANCE-MANAGEMENT REMOTE MONITOR SYSTEM OF POOL
Document Type and Number:
Japanese Patent JPH10115108
Kind Code:
A
Abstract:

To purify water quality while saving water by remotely controlling the monitor of the abnormal lowering of the water level of a pool, the limitation of the number of water supply and the continuation of water supply for a fixed time after full water at the time of water supply in response to a lowering of the water level of the pool.

When the lowering of a water level in a pool is detected by a water- supply sensor E2a for a water-level sensor 5 and a relay CR1 is operated, an (a) contact CR1 and a relay CR2 are turned on, an (a) contact CR2 for a feed valve circuit is turned on, and an automatic valve SV is opened and water supply is started. A timer T2 is interposed to the feed valve circuit, and the number of water supply a day is limited. When water is filled, a full-water sensor E1a detects full water, and the relay CR1 and the (a) contact CR1 are turned off, but a (b) contact CR1 for an overflow circuit is turned on. A current is flowed continuously through the relay CR2 from the (a) contact CR2 and an on-state is kept and water supply is continued, the pool is brought to an overflow state, and water is purified. A control wiring board 40 has a pool low water-quantity abnormal circuit 001 and a pool high water-quantity abnormal circuit 002, and both circuits 001, 002 transmit an alarm signal to a remote monitor through a telephone line.
