And personal safety and relevant range property safety the problems such as cannot ensure of user.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-Fig. 3 is referred to, Fig. 1 is the structural representation of closing pipe line control system provided in an embodiment of the present invention；Fig. 2
It is the mounting structure schematic diagram of closing pipe line control system provided in an embodiment of the present invention；Fig. 3 is carried for further embodiment of this invention
The mounting structure schematic diagram of the closing pipe line control system of confession.
In a kind of specific embodiment, the closing pipe line control system that the present invention is provided includes pressure sensor 1, control
Device processed 2 and warning device 3.Wherein, pressure sensor 1 is respectively provided with every layer of water inlet pipe and outlet pipe of pipeline, for gathering
The pressure signal of monitoring point, the two can be fixedly connected mode and be fixed by dismountable, and controller 2 is by pressure sensor 1
Whether the normal pressure value of the monitoring point prestored in the pressure signal of collection and database is compared, and judges monitoring point pressure value
Decline, if so, then sending enabling signal to warning device 3, warning device 3 is alarmed according to predetermined manner, and predetermined manner can
Alarmed including the mode such as buzzer or indicator lamp.Certainly, it is only herein more preferred embodiment, in other implementations
In example, can voluntarily set according to actual needs, within the scope of the present invention.
The normal pressure value of each monitoring point need to gather pressure as the point in data when system is normally run in database
The pressure comparison value of storehouse memory storage, it is general, liquid in pipe pressure balance stabilising arrangement is installed, to ensure to be monitored in pipeline
The stabilization of the collection pressure of system.
Specifically, also including for be connected with the signal of controller 2 and can show that the positional information of malfunction monitoring point shows
Display screen.
When point pressure decline is monitored, controller 2 sends a control signal to display screen, and display screen sends according to controller 2
Control signal show the positional information of malfunction monitoring point, including the nearest water inlet pipe in distance fault monitoring point and water outlet pipe part
Monitoring point information, to point out staff fault location information.Certainly, in other embodiments, it is also possible to do not carry out above-mentioned setting
Put, can voluntarily be configured.
Further, warning device 3 includes buzzer and/or indicator lamp.
In a kind of specific embodiment, warning device 3 can respectively control buzzer and indicator lamp to start to be alarmed,
Certainly, in other embodiments, it is also possible to a startup in only both control, or in other embodiments, other are controlled
The warning device 3 of form is alarmed, and within the scope of the present invention, can be voluntarily configured as needed.
Further, controller 2 is additionally operable to：
When monitoring point pressure value declines, the control valve 4 of water inlet pipe and outlet pipe where control malfunction monitoring point is closed
With the water source at disengagement failure monitoring point.
In order to the liquid for reducing loss causes secondary pollution to surrounding environment, malfunction monitoring point can be controlled by controller 2
The water inlet pipe at place and the control valve 4 of outlet pipe are closed, to improve safety coefficient of the pipeline by region.Control valve is generally electricity
Dynamic two-port valve, is only herein more preferred real certainly, in other embodiments, it is also possible to select the control valve of other forms
Scheme is applied, within the scope of the present invention.
Specifically, controller 2 is additionally operable to：
Controller is connected with master control valve signal so that when monitoring point pressure value declines and monitoring point is in main line, control is led
Control valve is closed and starts autostop program.
When monitoring point is on main line, start autostop program, the pressure value of the monitoring point of each branch road now
It is abnormal, in order to prevent controller 2 from proceeding detection, there is maloperation, autostop program stopped main frame can be started, followed
The operation of ring water pump.
In a kind of specific embodiment, the present invention provide system operationally, the pressure of each pipeline inner pressure monitoring point
Power is in stable state, pre- in pressure data and database that controller 2 is uploaded to the pressure sensor 1 of each monitoring point in time
The normal pressure value of each monitoring point deposited is contrasted, once find certain monitoring point pressure have abnormal decline, can and alarm.
When system shutdown, the system of monitoring is in state out of service, and controller 2 is automatically monitoring point in database
In overpressure value of reduced pressure force value when being switched to system shutdown, and carried out with the real-time pressure of each monitoring point that is uploaded
Contrast, control centre is still normally running herein, can be reacted in time when each monitoring point pressure anomaly.Above two works
State can be switched over according to the keying of circulating pump, or in another embodiment, can be opened according to the flow installed on pipeline
Keying in extension is switched over.
When system maintenance, because manifold pressure plays pendulum, easily cause the maloperation of controller 2, controller 2
The state of being stopped is should be at, when that need to detect that a certain areal pressure changes, can be used and manually be detected.
Each embodiment is described by the way of progressive in this specification, and what each embodiment was stressed is and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or uses the present invention.
Various modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The scope most wide for causing.
