Water level detecting system to power on first use time, user can set the number of detecting electrode, and be No. 1 electrode according to lowest water level electrode, be No. 2 electrodes on No. 1 electrode ... until the order of n electrode (n >=2) is placed in tank successively.Then detect current level, and current level is shown in display device 302.Electrode corresponding to current level, as reference electrode, is stored in reference electrode in storage 308, as the benchmark that next time judges.
Such as, according to order from top to bottom place respectively No. 1, No. 2, No. 3 ..., n electrode (electrode of other quantity can certainly be set), signal is sent according to high position electrode, the principle of lower position electrode Received signal strength, No. 1 electrode can only be used for Received signal strength, and n electrode can only be used for sending signal.Reference electrode when dispatching from the factory can default setting be n electrode.
Detection method specifically comprises following steps:
Interval N minute (as 10 minutes) detect actual water level position.Detection method is that reference electrode sends detection signal, the whether conducting of an electrode below judgment standard electrode.
S1 a: if electrode (the i.e. n-1 electrode) conducting below reference electrode (being designated as n electrode), then illustrate there is water between n electrode and No. n-1, water level is on n electrode place or No. n.
Again, signal is sent by n+1 electrode, detection reference electrode (i.e. n electrode) whether conducting, if do not have conducting, illustrate that water level does not arrive n+1 electrode place, can show that water level is at n electrode place, is then recorded in central processing unit 304 using n electrode as reference electrode in conjunction with these 2 times judgements, interval N minute again detection reference electrode whether in actual water level position; If n electrode conduction, then continue to send signal by n+2 electrode, judge the whether conducting of n+1 electrode, the like.
S2: if the electrode (i.e. n-1 electrode) below reference electrode (being designated as n electrode) does not have conducting, then illustrate that water level is below n electrode.
Again, signal is sent by n-1 electrode, judge the whether conducting of n-2 electrode, if n-2 electrode conduction, then illustrate that water level is at n-1 electrode place, in conjunction with this test case of 2 times, thinks that water level is at n-1 electrode place, then n-1 electrode is recorded in central processing unit 304 as reference electrode, interval N minute again detection reference electrode whether in actual water level position; If n-2 electrode does not have conducting, then continue to send signal by n-2 electrode, judge the whether conducting of n-3 electrode, the like.
S3: when next sense cycle starts, system reads reference electrode and continues to detect according to said process from central processing unit 304.
No. 2 electrodes, it is to be noted that in the process detected, if reference electrode becomes nethermost No. 2 electrodes and No. 1 electrode does not have conducting, are then kept in central processing unit 304 as reference electrode by those skilled in the art, so that next cycle continues to detect; If reference electrode becomes uppermost n electrode and n-1 electrode conduction, then n electrode is kept in central processing unit 304 as reference electrode, so that next cycle continues to detect.
In technique scheme, the time that reference electrode transmits can be arranged arbitrarily, as being set to 10 seconds.
The technical scheme of the above embodiment of the present invention, by optimizing the method for water level detecting, decreases the time of electrifying electrodes, has delayed the process of electrode fouling, save electrodes maintenance cost.
More than be described with reference to the accompanying drawings technical scheme of the present invention, the present invention proposes a kind of water level detecting scheme for tank newly, under guarantee accurately detects the prerequisite of water level, the process of electrode fouling can be delayed, effectively saves the cost of electrodes maintenance.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
