Just it is able to achieve, once there are failures may the loss that can not be retrieved.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of control systems of water flow in detection water pipe, are able to detect water
The variation of stream also has the characteristics of simple, easy of integrationization and high reliablity, and the surveyed liquid of inductive pole piece discord directly contacts,
When having water flow to flow through in water pipe, control loop triggering is worked by control system, and secure safety is high, brings more to user
Add safe and reliable product usage experience.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: provide water in a kind of detection water pipe
The control system of stream, including inductive pole piece, capacitance detecting sensing unit, control processing unit, control output unit and power supply
Power supply unit, the inductive pole piece pass through capacitance detecting sensing unit and control processing unit communication connection, the control
Processing unit is also connected with control output unit and power supply unit respectively.
In a preferred embodiment of the present invention, the input voltage of the power supply unit is AC85-265V.
In a preferred embodiment of the present invention, the inductive pole piece is fixed on water pipe or is fitted in using cluster
Mode on the outside of tube wall.
In a preferred embodiment of the present invention, the control processing unit is controlled using SCR control or relay
Or controlled control device.
In a preferred embodiment of the present invention, the capacitance variations of capacitance detecting sensing unit acquisition sensing chip
Value.
The beneficial effects of the present invention are: the control system for detecting water flow in water pipe of the invention, is able to detect the change of water flow
Change, also there is the characteristics of simple, easy of integrationization and high reliablity, the surveyed liquid of inductive pole piece discord directly contacts, and works as water pipe
In when there is water flow to flow through, control loop triggering is worked by control system, and secure safety is high, brings to user safer

Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, in which:
Fig. 1 is the structural block diagram of a preferred embodiment of water flow control system in present invention detection water pipe.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
As shown in Figure 1, the embodiment of the present invention includes:
The control system of water flow in a kind of detection water pipe, including inductive pole piece, capacitance detecting sensing unit, control processing unit,
Output unit and power supply unit are controlled, the inductive pole piece passes through capacitance detecting sensing unit and control processing unit
Communication connection, the control processing unit are also connected with control output unit and power supply unit respectively.
Among the above, the power supply unit uses input voltage for the power supply of AC85-265V；The capacitance detecting
The capacitance variations value of sensing unit acquisition sensing chip.Wherein, capacitance detecting sensing unit uses inductive pick-up.
Capacitance detecting sensing unit receives inductive signal in inductive pole piece and handles these signal values, then compares output letter
Number to control processing unit.It controls processing unit and receives the signal from capacitance detecting sensing unit, convert a signal into control
Signal and making can control output unit, control controlled components work.
Further, the inductive pole piece is consolidated in such a way that cluster is fixed on water pipe or is fitted on the outside of tube wall
It is scheduled on outside.Inductive pole piece discord water has direct contact, meanwhile, the control processing unit is by SCR control or relay
Device control or controlled control unit composition, guarantee that system is safe and reliable.
Capacitive detection circuit design is acquired, principle is: when there is water flow to flow through due to producing between inductive pole piece and water
Raw capacitance is changed, and inductive pick-up acquires the capacitance of this variation, guarantees that the acquisition of signal more accurately may be used
It leans on.
Power supply uses input voltage for AC85-265V power supply power supply scheme, and control system detection water pipe has water flow, triggering letter
Number, and ignore water quality and ignore the influence that water quality contains a large amount of impurity, guarantee the operation reliable and secure by control section.
The control system of water flow compared with prior art, has the advantages that in detection water pipe of the invention
1. controller is periodically detected water flow variation in water pipe；
2. high sensitivity, water-flow signal can also be checked in the case where very little water flow；
3. not influenced by water quality；
4. discord water has direct contact.
In conclusion the control system for detecting water flow in water pipe of the invention, is able to detect the variation of water flow, also there is letter
Single, the characteristics of easy of integrationization and high reliablity, inductive pole piece surveyed liquid of getting along well directly is contacted, when having water flow to flow through in water pipe
When, control loop triggering is worked by control system, and secure safety is high, brings more safe and reliable product to make to user
With experience.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
