Shown in Figure 2, the utility model additionally provides a kind of point procuratorial organ of the above-mentioned strainer with fault detection system
Method is preset in control device into water level monitoring range and water outlet level monitoring range；It includes the following steps：
A0：Control device judges the liquid that the liquid level that water inlet liquid level sensor 3 is monitored is monitored with water outlet liquid level sensor 1
Whether position is respectively in the range of preset water inlet level monitoring and in the range of preset water outlet level monitoring, if it is not, then can determine whether
It has into water liquid level sensor 3 and water outlet liquid level sensor 1 be any or whole failures, into A3；If so, into A1.
A1：Liquid level sensor 3 of intaking monitors the liquid level of 2 front end of strainer ontology；It is discharged liquid level sensor 1 and monitors strainer ontology
The liquid level of 2 rear ends, into A2；
A2：Control device judges that the liquid level that water inlet liquid level sensor 3 is monitored is monitored with the water outlet liquid level sensor 1
Liquid level between liquid level difference whether be more than preset liquid level difference, if it is not, then strainer is normal, if so, strainer exist therefore
Barrier, into A3.
A3：When strainer is there are during failure, warning device alerts.
Typically, strainer breaks there are failure including water inlet liquid level sensor 3 or short circuit, water outlet liquid level sensor 1 are broken
Line or short circuit and strainer block, specifically,
Control device judges the liquid level H that water inlet liquid level sensor 3 is monitored2The liquid monitored with water outlet liquid level sensor 1
Position H1Whether respectively in the range of preset water inlet level monitoring and in the range of preset water outlet level monitoring, if H6≤H2≤H5
And H4≤H1≤H3, then intake liquid level sensor 3 and water outlet liquid level sensor 1 it is normal, if H2＞ H5Or H2＜ H6, then into aqueous
Level sensor 3 breaks or short circuit, if H1＞ H3Or H1＜ H4, then be discharged liquid level sensor 1 break or short circuit.
In A0, liquid level sensor carry out self-test when, though water inlet liquid level sensor 3 and water outlet liquid level sensor 1 which
A elder generation's self-test, as long as the liquid level of the Sensor monitoring of first self-test not in preset monitoring range, i.e. warning device alerts, such as
The sensor of first self-test of fruit is normal after testing, then self-test is carried out to second sensor, if the sensing of second self-test
Not in preset monitoring range, i.e. warning device alerts the liquid level of device monitoring, if normally, into A2.
When the liquid level that water inlet liquid level sensor 3 is monitored is in the range of preset water inlet level monitoring, and is discharged liquid level and passes
When the liquid level that sensor 1 is monitored is in the range of preset water outlet level monitoring, i.e. H6≤H2≤H5And H4≤H1≤H3, control device
Further judge the liquid level that water inlet liquid level sensor 3 is monitored and the liquid level being discharged between the liquid level that liquid level sensor 1 is monitored
Whether difference is more than preset liquid level difference, if H2-H1＞ N, then strainer blocks, if H2-H1≤ N, then strainer is normal.
When any of the above-described failure occurs, warning device can send out alarm immediately, inform staff to said circumstances into
Row excludes, you can finds specific failure cause.
The utility model is not limited to the above embodiment, for those skilled in the art, not
Under the premise of being detached from the utility model principle, several improvements and modifications can also be made, these improvements and modifications are also considered as this reality
