Abstract
The invention discloses a water leakage failure alarming device for a school toilet. The device consists of a flow sensor, a PLC (programmable logic controller) and an alarming indicator lamp, wherein the flow sensor is used for detecting water leakage flow, converting flow non-electricity signal into an electrical signal, and inputting the electrical signal to the PLC; and the PLC is used for executing an alarming program, and outputting an instruction to turn on the alarming indicator lamp to indicate a water leakage failure.
Description
Affiliated technical field
The present invention relates to a kind of school toilet water leakage fault warning device, device that especially can automatic alarm when there is water leakage fault in school's toilet supply channel.
Background technology
At present, known school toilet does not have the water leakage fault warning facility, and the student washes and usually forgets behind the hand and close water swivel tight or the water valve failure and other reasons causes water to leak for a long time.
Summary of the invention
Exist water leakage fault can not in time find the deficiency of repairing in order to remedy existing school toilet, the invention provides a kind of school toilet water leakage fault warning device, can head it off.
The present invention solves the scheme that its technical matters adopts: adopt the water leakage fault warning device that is comprised of flow sensor, the sharp alarm lamp of PLC.Flow sensor detects the water leakage flow and the flow non-electric charge quantity signalling is converted to electric signal and inputs to PLC, and PLC execution alert program output order is lighted alarm lamp and indicated and has water leakage fault.Flow sensor is highly sensitive, and the PLC program execution time is short, so rapid Realtime Alerts, whole device can long time continuous working, does not need the people to participate in, and has realized automatic alarm.It is eye-catching that alarm lamp shows, and each lamp carried out geocoding, just can know the fault zone according to bright lamp, in time repairing is provided convenience.
The invention has the beneficial effects as follows, simple in structure, easy to install, can continuous working, to the automatic Realtime Alerts of water leakage fault.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is the structural map of one embodiment of the invention.
Embodiment
In the accompanying drawings, flow sensor is installed in the pipeline that needs monitoring, the input interface of its signal output part access PLC.Write alert program by programmable device in PLC, the output port of alarm lamp and PLC is connected, and connects the input power of PLC and PLC is fixed on the frame.
In an embodiment shown in the drawings, during use, press the PLC start button, the water leakage fault warning device brings into operation, in flow sensor, there are current out-of-date, sensor converts the flow non-electric charge quantity signalling to electric signal and inputs to PLC, because leakage can exist certain hour so this signal also can have a period of time, PLC adopts the scan round mode to work, and carries out the alert program output order when input end has signal from flow sensor and makes alarm lamp light indication to have water leakage fault when PLC scans.
