Description
Technical field
The present invention relates to a kind of intelligent control supervisory system, relate in particular to a kind of water pump intelligent control supervisory system, be mainly used in the water system on the large public building.
Background technique
Along with developing rapidly of China's modernization, variation with rapid changepl. never-ending changes and improvements is just taking place in the urban and rural buildings cause.Various construction engineerings spread all over the place, and its scale, quality, speed of application and construction technology have all got into a new stage.Large public building and other tourist hotel of various level, restaurant emerge in large numbers; The emphasis of state fundamental construction has been classified in the construction of housing as, and completed floor space all has increase by a relatively large margin every year; Various novel buildings, high level and skyscraper development are very fast; Various New Building Materials, novel construction appliance, method of construction and technology etc. emerge in an endless stream, and these have all proposed new requirement to architectural electricity.
Below sketch the main design content and the current situation of architectural electricity:
Building's electrical design mainly comprises: transformation and distribution system, electric power system, lightning protection earthing system, illuminating system, air-conditioning system, supply and drain water system, elevator system, fire fire-fighting system, safety and protection system or the like.
In general, transformation and distribution system mainly comprises in the building: high and low pressure system, transformer, standby power system etc.; Electric power system mainly comprises electric power system distribution and control; Lightning protection earthing system comprises anti-lightning wave intrusion, anti-lightning induction, ground connection, equipotential bonding and local equipotential bonding, auxiliary equipotential bonding or the like; Illuminating system then comprises all kinds of illuminations of indoor and outdoor.
At present, huge variation has taken place at the technology and the product of these systems of strong power part in the Chinese architecture electrical technology, like the high-tension switch cabinet in the high-pressure system; Developed into vacuum circuit breaker and SF6 circuit breaker or the like, not only volume is little, and capacity of short circuit is also high; The cabinet size is also little many than original cupboard, because circuit breaker does not have any oil, fireproof performance improves greatly; And can put altogether in the room with other low-voltage equipment, both save the space, make things convenient for management again.Low-voltage circuit breaker is big from the volume in past, capacity of short circuit develops into big electric current, high breaking capacity, little, the stable performance of volume for a short time, makes system more safe and reliable, and has brought convenience to design.The appearance of dry-type transformer has not only improved installed power, more because there is not the transformer leakage of oil in it and the possibility of breaking out of fire, makes it to be arranged on easily the inside of building, more directly is deep into load centre.See that from the power supply aspect equipment for allowing interruption of power supply at Millisecond has then extensively adopted UPS equipment.
Present situation and problem for the building's electrical design of present majority mainly contain following 3 points:
One, mostly the control mode to architectural electricity is separate equipment control, when normal operation and monitoring, is not very convenient.
Two, in the secondary control loop design of architectural electricity, adopted is conventional means of relay-contactor control mode more.This mode has adopted the electromechanical combining form, though be convenient to common electrical category technician's maintenance, the electric elements that uses is many, volume is big, the contact is many, rate of fault is big, the life-span is short, so low or the like the problem of reliability of operation.
Three, modern architecture is equipped with a large amount of electrical equipment, electrical system and electric power system in addition; Control as the motor of power equipments such as blower fan, water pump, elevator system, change/electrical distribution system, lighting electric system etc. finally all realizes that through electric control system mostly final actuator is motor.Show in " research report of motor speed adjusting technique industrialization approach and countermeasure "; 66% of China's generating total amount consumes on motor; All kinds of motor operational efficiency are than low 10～20 percentage points of external advanced level; Therefore, the motor energy consumption issues in the architectural electricity is another aspect that haves much room for improvement.
For example, the present large-scale tall buildings and the water supply of residential quarters still adopt traditional fixed frequency three phase alternating current motor to drag load mostly, adopt modes such as elevated tank or barometric tank pressurization.Along with season, round the clock, the influence of changing factor such as time; Water consumption differs greatly; Pipe network water pressure is unstable, and is uneven between water supply and the water, and owing to adopt traditional fixed frequency three phase alternating current motor to drag load; Motor generally is in operation and all will carries out Load Regulation, and corresponding flow also will be followed the tracks of adjusting.Tradition is regulated the regulating method of the valve opening of inlet or outlet; The 30%-40% of water pump power consumption is consumed in regulating valve and pipe network pressure drop; It is a kind of of poor benefits, energy consumption is big, device damage is fast, amount of maintenance is big, operating cost is high backward way; Not only caused the huge waste of electric energy, and sizable gap has also been arranged with the economical operation standard.
Summary of the invention
For addressing the above problem, the invention provides the water pump intelligent control supervisory system that system's operation stability was controlled, cut down the consumption of energy, increases to a kind of ability conduct monitoring at all levels.
