Abstract
The invention belongs to the field of integrated automation of a power system and relates to development and realization of a multi-pump intelligent controller. The multi-pump intelligent controller is developed to realize the multi-pump integrated control; when to start the pump, how many pumps to start and which pumps to start are automatically judged according to the operating time, operating fault and operating mode of the pumps and various operating indexes are displayed in real time; when necessary, the controller can be connected to the network and share information; and the controller does not only controls the water pump, and can be also used on occasions where the distance between live units is far, and corresponding chain can be realized. By adopting the multi-pump intelligent controller, the high cost of the programmable controller is avoided, the subsequent maintenance is convenient, and the maintenance cost is reduced; meanwhile, the automatic operating problem of the plant water pump or the fan is solved.
Description
Technical field
The present invention relates to Ship Electrical Power System comprehensive automation field, the realization of refering in particular to a kind of many pumps intelligent controller.
Background technique
Present large enterprise gives a long price for external control apparatus and reaches target as all adopting between each water head site of power station, no matter control the size of occasion; The identical general layout of basic employing; This just causes the waste of a large amount of fund, and this is that medium-sized and small enterprises institute can not bear, and medium-sized and small enterprises occupy the component that quite weighs in China's economic; Inevitably, a large amount of electric energy are wasted.
The capital input of factory is divided into equipment input and later stage operation and maintenance cost in earlier stage; The controlling component of using the employing of the central controlled factory of many pumps at present is programmable controller PLC; As the core controller of modern industry automation, it has a lot of advantages: high like reliability, antijamming capability is strong; Highly versatile, control system is simple in structure; Perfect in shape and function adapts to wide; Programming is simple, easy master; Volume is little, and is in light weight, low in energy consumption, easy to maintenance; But the adaptation just because of it is wide, not specially to certain industry or the design of certain function, so on the construction project of ask for something function singleness; It is versatility too, causes the wasting of resources, and the maintenance cost in later stage also improves relatively.
This paper is conceived to reality to this problem, proposes the imagination of a kind of many pumps intelligent controller of exploitation, realizes many pumps centralized control; Solved expensive with programmable controller; Also help later maintenance, reduce maintenance cost, accomplished the automatic operation problem of plant water pump or fan etc. simultaneously.
Summary of the invention
The invention relates to a kind of realization of many pumps intelligent controller, the control system of being made up of this controller is particularly suitable for the occasion that how many pumps controlled.This controller is by display floater, keyboard, and main control module, communication module four parts constitute, and are connected to the upper monitoring interface through public network; The technical problem that relates to mainly contains the control algorithm of selecting pump, the optimization of program, between communication between the module and controller and public network based on communication issue of ICP/IP protocol etc.
Description of drawings
Fig. 1 system architecture diagram.
Embodiment
The design of this controller mainly is divided into two parts of hardware and software.
1. the hardware components structural drawing is as shown in Figure 1.
CPU selects 8051F020 or 040 for use, and it is the most complete high-performance single-chip microcomputer of 51F series function, and the I/O mouth has 64, can satisfy the requirement that many pumps control port demand is big, supports multiple bus mode; Peripheral signal is applied to the field fashionable receiving pipeline pressure signal (voltage or electric current) of constant pressure water supply from the analogue signal of some voltages (0-10V) or electric current (4-20mA); Electrical parameter comprises the running current of every pump, voltage, power; State control signal is a switching value, the run signal of every pump, trouble signal, this locality/remote signal, emergent stop signal; The control display floater is that controller parameter and the platform that shows running state are set.Through it, can select operating mode (constant pressure water supply pattern, operating mode on duty by turns, each pump independent operation mode), as in the constant pressure water supply pattern setting pressure being set, the parameter of regulator etc.; Operating mode on duty by turns can be provided with each pump impeller value time; Control panel can also be provided with some general parameters, and what receive like the periphery is voltage or current signal, and pump is in this locality or telecontrol, messaging parameter such as baud rate etc.Panel can show each pump operation state in addition; Switching value is through the drive circuit amplifying signal, the output of control relay node, and analog amount output is the signal of 0-10V voltage or 4-20mA electric current (can pass through the panel setting), the operation that comes control pump through frequency variator; Communication then adopts Ethernet to connect upper-position unit.
2. software section design.
1. through panel operating mode is set, relevant parameter (as above-mentioned) is set after getting into each pattern.
2. constant pressure water supply pattern, through setting pressure is set, each parameter of fuzzy is opened a variable frequency pump, if frequency reaches power frequency; Stop variable frequency pump and open a general pump; Water consumption increases, and pipeline pressure reduces, and then frequency conversion frequency increases; Otherwise then reduce, keep pipeline constant in the setting pressure value with this.
3. operating mode on duty by turns, is judged and is launched several pumps according to the liquid level or the pressure signal that receive to general pump; Launch which platform; If it is little that operation certain hour liquid level or pressure signal change, the longest one of time then out of service opens the shortest one working time; If fault appears in certain or a few pumps, then can guarantee to move the platform number, guarantee each pump longest-lived.
4. during each pump independent operation mode, each pump can independent operating, does not disturb mutually.
5. the state of the real-time display controller of upper-position unit also can be controlled it.
Claims (1)
1. patent of the present invention relates to a kind of exploitation and realization of many pumps intelligent controller, sends out many pumps intelligent controller a kind of, realizes many pumps centralized control, and according to working time of pump; Operation troubles, operating mode, when judgement opens pump automatically; Launch several, which platform, and show each operating index in real time; In case of necessity, can be linked to be network and share information, sort controller is used not just control of pump; Other have between group of motors or the unit the distant occasion of distance can use this controller, and realize chainly accordingly, and appearance had both solved expensive with programmable controller; Also help later maintenance, reduce maintenance cost, accomplished the automatic operation problem of plant water pump or fan etc. simultaneously.
