Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of Novel emulsion pump station intelligent and safe monitor in the utility model embodiment.
Embodiment
Provide preferred embodiment of the present utility model below, these embodiments unrestricted content of the present utility model.
embodiment
Please as shown in Figure 1, the utility model embodiment provides a kind of Novel emulsion pump station intelligent and safe monitor, main body is PLC4, this PLC4 connection mode analog quantity input expansion module 2, described analog input expansion module 2 receives the data that multiple sensor 1 sends, PLC4 also connects output unit 6, warning device 7 and liquid crystal display 3 respectively, and power supply 5 powers to above-mentioned modules.PLC4 adopts SIEMENS S7-200 small PLC.Described sensor 1 comprises pressure, pressure reduction, temperature and liquid level sensor.Analog input expansion module 2 has analog-digital conversion function.Described output unit 6 is solenoid valves that solid-state relay connects.Described warning device 7 is acousto-optic-electric comprehensive alarm devices.Described power supply 5 provides 660V ac power supply and 24V, 12V DC electrical source.
PLC4 of the present utility model adopts SIEMENS S7-200 small PLC as control centre.Its PLC body carries 24 I/0 switching values, has 2 485 communication interfaces and module expanded function, both can complete the real-time monitoring to emulsion power pack parameter, also can store malfunction history data, facilitate ex-post analysis and inquiry.
The function of Data collecting conversion is realized by sensor 1 and SIEMENS analog input expansion module 2.As requested, pressure, pressure reduction, temperature and liquid level 4 sensors that monitor is selected are intrinsic safety type, pumping station operation parameter is converted into 4 ~ 20mA current signal of standard by them, then these current signals is converted into through the modulus puocessing module of analog input expansion module 2 computing and the process of carrying out data in corresponding digital quantity feeding PLC4.
Output control function adopts solid-state relay to export, and realizes the driving to the output units such as solenoid valve 6 and control.Working state of system shows except current operating parameter in real time except on liquid crystal display 3 screen, all has corresponding tutorial light to indicate.
Because system has a large amount of parameters to need display, therefore native system adopts liquid crystal display 3 its Operational Limits of display and system mode in real time.Consider the particularity of application, liquid crystal screen needs to be arranged in explosion-resistant enclosure, and touch function cannot realize, so the mode external key of inventor's employing to PLC4 programming realizes the conversion between each function of liquid crystal screen.The major function that this liquid crystal touch screen completes:
1. real-time display device running state and all monitoring parameters;
2. arrange and revise machine state or operating parameter;
3. various instrument is replaced intuitively to show when overhaul of the equipments and system debug;
4., when system mode occurs abnormal, the storage autostore utilizing display device to carry and refreshing alarm parameters and corresponding moment, facilitate user to carry out inquiry and analysis to fault afterwards.
In order to ensure normal work, except 660V ac power supply, internal system additionally provides 24V and 12V two kinds of DC electrical source, provides energy respectively to PLC4, sensor 1, liquid crystal display 3 and solenoid valve etc.
The utility model adopts multi-functional large-sized liquid crystal touch screen as show tools, not only achieves the touring centralized displaying of parameter, also achieves the mutual in groups online modification adjustment of parameter, also can carry out real-time monitored to real-time clock and warning message.Carry out analysis and the inquiry of fault for the convenience of the user, native system has carried out historical information storage for alarm parameters and fault moment, allow authorized user to carry out on-site parameters interactive modifying and warning message history to return and look into, make system have good man-machine interaction, user uses and observes very directly perceived and convenient.
The monitor that the utility model provides mainly possesses following functions:
(1) Real-Time Monitoring of each key position parameter;
(2) fault message history is returned and is looked into;
(3) scene of systematic parameter and real-time clock is arranged and change;
(4) pass word function, only has and could carry out optimum configurations and retouching operation to system by the people of authentication;
(5) be reserved with communication interface, system can realize network savvy with upper-position unit.
Facts have proved, this system rejection to disturbance ability is strong, reliability is high, extensibility good, achieves well and monitors the dynamic and intelligent of mine emulsion power pack, has stronger use value to safe, reliable, the stable operation of mine production system.
