Description
Technical field
The utility model relates to outdoor road roof deicing or snow melting technical field, specifically relates to a kind of deicing or snow melting control system.
Background technology
The accumulated snow on current outdoor road in winter roof is to the go off daily of people, and productive life and personal property all constitute certain threat.The Related product about deicing or snow melting of more domestic manufacturers produce, employing be measure accumulated snow humidity to carry out corresponding deicing or snow melting operation control.But in the winter that the north is cold, because of sensitivity decline and even loss of function that open-air seasoning, dust storm great Yi cause humidity sensor, cause device systems normally to run.Along with the development of domestic economy, the defensive ability/resistance ability of some road and buildingss etc. to disasters such as extreme weathers is poor, and accumulated snow icing phenomenon causes road traffic accident to take place frequently, the blocked up accident such as cause that buildings collapses of accumulated snow on buildings.
Utility model content
The purpose of this utility model is to provide kind of an a kind of deicing or snow melting control system, and this system sensitivity is high and stable, simple to operate, effectively can eliminate the ice and snow on outdoor road in winter roof.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of deicing or snow melting control system, comprise PLC, outdoor temperature sensor, for measure ice-snow thickness ultrasonic distance-measuring sensor, for setting the man-machine dialogue equipment of snow melt temperature and thickness parameter, described outdoor temperature sensor, ultrasonic distance-measuring sensor signal output part are connected with PLC signal input part, man-machine dialogue equipment is connected alternately with PLC, and PLC signal output part is connected with deicing or snow melting heating unit.
Controlled deicing or snow melting control system by above-mentioned control method, deicing or snow melting system effectively can be removed the ice and snow on outdoor road roof, and this system automation degree is high, not climate condition impact, highly sensitive, simple to operate, and safety is energy-conservation.
Accompanying drawing explanation
Fig. 1 is the utility model system schematic.
Embodiment
A kind of deicing or snow melting control system, comprise PLC 10, outdoor temperature sensor 20, for measure ice-snow thickness ultrasonic distance-measuring sensor 30, for setting the man-machine dialogue equipment 40 of snow melt temperature and thickness parameter, the signal output part of described outdoor temperature sensor 20, ultrasonic distance-measuring sensor 30 is connected with PLC 10 signal input part, man-machine dialogue equipment 40 is connected alternately with PLC 10, and PLC 10 signal output part is connected with deicing or snow melting heating unit 50.
The control method of said system comprises following operation steps:
After a, system boot, started temperature and the thickness parameter of snow melt by man-machine dialogue equipment 40 initialization system;
B, PLC 10 receive the actual ice-snow thickness value signal that actual outdoor temperature value signal, the ultrasonic distance-measuring sensor 30 measured from the signal of the temperature of beginning snow melt of setting in man-machine dialogue equipment 40 and thickness parameter, outdoor temperature sensor 20 are measured, whether then the signal of PLC 10 to above-mentioned setting value and actual measured value carries out com-parison and analysis, make command adapted thereto control deicing or snow melting heating unit 50 and work.
Design temperature parameter comprises higher limit and lower limit, and setting thickness parameter also comprises higher limit and lower limit:
When temperature sensor detects that actual outdoor temperature is lower than design temperature parameter lower limit value, PLC 10 signal exports, deicing or snow melting heating unit 50 is started working, during system cloud gray model, once temperature sensor detects that actual outdoor temperature is higher than design temperature parameter upper limit value, PLC 10 signal exports, and deicing or snow melting heating unit 50 quits work.Generally, when outdoor temperature reaches design temperature parameter upper limit value, outdoor temperature is higher, and accumulated snow can melt by nature, without the need to electrical heating, reaches energy-conservation object.
The thickness of the actual outdoor accumulated snow recorded when distance measuring sensor 30 exceedes the higher limit of setting thickness parameter, deicing or snow melting heating unit 50 self-starting, and system sends warning, the thickness of the outdoor accumulated snow of the reality that always works is less than the lower limit of setting thickness parameter, and carry out the time delay snow melt of a period of time, guarantee that all snow meltings are clean, the time of time delay snow melt is set by man-machine dialogue equipment 40, reach time delay snow melt setting-up time system and will cut off electrically heated output, deicing or snow melting heating unit 50 quits work.
Another special circumstances, when outdoor temperature sensor 20, ultrasonic distance-measuring sensor 30 break down, manually boots system by man-machine dialogue equipment 40, directly controls deicing or snow melting heating unit 50 carry out work by PLC 10.So just substantially increase the operability of this control system.
Said system, once break down and can also be given the alarm by man-machine dialogue equipment, takes corresponding safe operation to point out staff.
Further technical scheme, described man-machine dialogue equipment 40 comprises entry terminal touch-screen.Can setting parameter be carried out by this touch-screen, and can show in time running situation.
Further technical scheme, deicing or snow melting heating unit 50 comprise connect successively power supply 51, isolating switch 52, A.C. contactor 53, lead wiring terminal row 54, heating cable 55.Described electrical equipment power supply 51, isolating switch 52, A.C. contactor 53, lead wiring terminal row 54, heating cable 55 connect and compose power circuit successively, are melted by heating cable 55 pairs of ice and snow.A.C. contactor 53 plays a part circuit folding, guarantee that system cloud gray model is normal, and the isolating switch 52 available protecting safety of deicing or snow melting heating unit 50 place circuit, prevents the faults such as short circuit from damaging deicing or snow melting heating unit 50.
Further technical scheme, the folding of A.C. contactor 53 described in PLC 10 signal output part and relay 60 connection control.PLC 10 sends corresponding instruction and whether passes through to control to electric current in relay 60, as having electric current to pass through in relay 60, so connected A.C. contactor 53 will make the deicing or snow melting heating unit 50 at its place be in "on" position, deicing or snow melting heating unit 50 starts to carry out deicing or snow melting work, in relay 60, no current passes through, and deicing or snow melting heating unit 50 does not carry out work.
Described PLC 10, man-machine dialogue equipment 40 are all connected with described power supply 51.Namely power supply 51 not only provides electric energy to deicing or snow melting heating unit 50, but also provides electric energy to PLC 10, man-machine dialogue equipment 40.
