S2:If the electrode (i.e. n-1 electrodes) of reference electrode (being designated as n electrodes) below is not turned on, say Bright water level is below n electrodes.
Again, signal is sent by n-1 electrodes, judges whether n-2 electrodes turn on, if n-2 electrode conductions, Illustrate water level at n-1 electrodes, with reference to this test case of 2 times, it is believed that water level is at n-1 electrodes, then by n-1 electricity Pole is recorded in central processing unit 304 as reference electrode, and whether interval N minutes detect reference electrode in actual water level position again Put;If n-2 electrodes are not turned on, continue to send signal by n-2 electrodes, judge whether n-3 electrodes turn on, successively Analogize.
S3:When next detection cycle starts, system reads reference electrode from central processing unit 304 and continued according to upper The process of stating is detected.
Those skilled in the art should be noted:During detection, if reference electrode is changed into nethermost No. 2 Electrode and the no conducting of No. 1 electrode, then be stored in central processing unit 304 using No. 2 electrodes as reference electrode, so as to next cycle Continue to detect;If reference electrode is changed into uppermost n electrodes and n-1 electrode conductions, using n electrodes as reference electrode It is stored in central processing unit 304, so that next cycle continues to detect.
In the above-mentioned technical solutions, the time of reference electrode transmission signal can arbitrarily be set, and such as be arranged to 10 seconds.
The technical scheme of the above embodiment of the present invention by optimizing the method for water level detecting, reduce electrode energization when Between, delay the process of electrode fouling, save electrodes maintenance cost.
Technical scheme is described in detail above in association with accompanying drawing, the present invention proposes a kind of new water storage that is used for and held The water level detecting scheme of device, the process of electrode fouling on the premise of ensureing accurately to detect water level, can be delayed, effectively saved The cost of electrodes maintenance.
