Description
Technical field
This utility model relates to a kind of alarm monitoring system, particularly relates to a kind of liquid level warning monitoring system.
Background technology
In the enterprise production process of industrial circle, the hydraulic oil in fuel tank is squeezed into hydraulic cylinder by fluid pressure line by oil pump
In, thus pushing equipment action.When external equipment or pipeline leakage of oil and do not found in time, then can be caused system termination of pumping,
Produce and stop, even because discovery leakage of oil the most in time causes fuel tank to fan the air thus causes oil pump to burn out.
The underground that existing hydraulic oil unit is arranged at, the work of Hydraulic Cylinder in its geographical position distance factory floor
Equipment is far.Although equipped with the liquidometer for detecting oil tank liquid level on the fuel tank of hydraulic oil unit, when the liquid level of fuel tank reduces
To when jumping pump liquid level, stop oil pump and run, thus reach to protect the purpose of oil pump, but before oil pump is out of service, it is impossible in time
Termination of pumping information is sent in workshop, causes the operator in factory floor or engineer to fail in advance and carry out shutdown standard
Standby, when hydraulic test stops action suddenly, easily cause and just damage at processed material, scrap, not only waste material is very
To the production schedule that can affect whole production line.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of liquid level warning monitoring that can reduce fault in production
System.
This utility model solves the liquid level warning monitoring system that its technical problem is used, including the liquid being arranged in fuel tank
Position meter, described liquidometer electrically connects with PLC, described PLC and the man-machine boundary being arranged in workshop on operating board
Face, be arranged on safeguard night shift room alarm device electrical connection；The real-time level value that liquidometer is detected by described PLC is with pre-
If alarm liquid level value compare, when real-time level value≤alarm liquid level value, send alarm signal, described PLC is sent out
The alarm signal gone out divides two-way to transmit simultaneously, and a road is transferred to the man machine interface on operating board, and another road is transferred to safeguard on duty
The alarm device of room.
Further, described alarm device is audible-visual annunciator.
Further, in workshop, alarm lamp on operating board, it is additionally provided with.
Further, described liquidometer uses capacitance type oil level sensor.
Further, described capacitance type oil level sensor is arranged in fuel tank by flange.
The beneficial effects of the utility model are: in using liquid level warning monitoring system of the present utility model monitoring hydraulic oil unit
The oil mass of fuel tank, when the alarm liquid level value of the real-time level value≤default of liquidometer detection, PLC sends alarm signal
Number, the alarm signal that described PLC sends divides two-way to transmit simultaneously, and a road is transferred to the man machine interface of operating board, another
Road is transferred to the alarm device of night shift room；Operator or engineer in factory floor show according to the man machine interface of operating board
The warning message shown, takes measures to the material to be machined on production line in time, carries out equipment downtime preparation in advance, prevents
Equipment stops suddenly action to be caused and just damages at processed material, scrap；Meanwhile, safeguard that the staff of night shift room is according to value
The alarm signal that the alarm device of class room sends goes to investigate leak source in time, solves problem；Reduce fault in production and risk.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Shown in figure: fuel tank 1, liquidometer 2, PLC 3, man machine interface 4, alarm device 5, alarm lamp 6, hydraulic pressure set
Standby 7, operating board 8, safeguard night shift room 9.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, liquid level warning monitoring system of the present utility model, including the liquidometer 2 being arranged in fuel tank 1, institute
State liquidometer 2 to electrically connect with PLC 3, described PLC 3 and the man machine interface 4 being arranged in workshop on operating board,
It is arranged on and safeguards that the alarm device 5 of night shift room electrically connects；The real-time level value that liquidometer 2 is detected by described PLC 3 is with pre-
If alarm liquid level value compare, when real-time level value≤alarm liquid level value, send alarm signal, described PLC 3
The alarm signal gone out divides two-way to transmit simultaneously, the man machine interface 4 that a road is transferred on operating board, and another road is transferred to safeguard on duty
The alarm device 5 of room.
Use the oil mass of fuel tank in liquid level warning monitoring system of the present utility model monitoring hydraulic oil unit, when liquidometer 2 is examined
During the alarm liquid level value of the real-time level value≤default surveyed, PLC 3 sends alarm signal, and described PLC 3 sends
Alarm signal divide two-way to transmit simultaneously, a road is transferred to the man machine interface 4 of operating board, and another road is transferred to the warning of night shift room
Device 5；The warning message that operator in factory floor or engineer show according to the man machine interface 4 of operating board, in time
Material to be machined on production line is taken measures, carries out hydraulic test 7 in advance and shut down preparation, prevent hydraulic test 7 from dashing forward
So stopping action causing and just damages at processed material, scrap；Meanwhile, safeguard that the staff of night shift room is according to night shift room
The alarm signal that sends of alarm device 5 goes to investigate leak source in time, solves problem.
Alarm device 5 can only send acoustical signal, it is also possible to only sends photosignal, as preferred embodiment,
Described alarm device 5 is audible-visual annunciator.
As preferred embodiment, in workshop, on operating board, it is additionally provided with alarm lamp 6.Prevent the behaviour in factory floor
Make workman or engineer notices that warning message that man machine interface 4 shows finds early warning signal the most in time the most in time.
As preferred embodiment, described liquidometer 2 uses capacitance type oil level sensor.Capacitance type oil level sensor is adopted
With highly integrated special capacitance measurement chip, through accurate temperature-compensating and linear correction, there is high accuracy, high stability
With advantages such as test constantlies.Described capacitance type oil level sensor can be arranged in fuel tank 1 by flange.
