Description of drawings
Fig. 1 is the functional block diagram of the central cooling control system of boats and ships of the present invention.
The specific embodiment
The principle of the central cooling control system of boats and ships of the present invention is as shown in Figure 1; Comprise collecting sensor signal processing module, decision-making and optimizing calculation module, actuating mechanism controls module, display module, alarm module, communication module; The signal of collecting sensor signal processing module collection passes to decision-making and optimizing calculation module; The collecting sensor signal processing module; Specifically comprise sea temperature acquisition processing module, fresh water temperature acquisition processing module, pressure signal acquisition processing module, differential pressure signal acquisition processing module, each module is gathered original signal, is decision-making and the optimizing calculation module parameter that provides access.Decision-making and optimizing calculation module; According to current waters temperature; The low-temperature end temperature value in the water-sprinkling loop that combined sensor signal acquisition process module sends is launched the initialize data library information, uses feedforward, feedback PID control method; Calculate current sea water pump that should start and water-sprinkling pump platform number, and the aperture of triple valve.The signal that decision-making and optimizing calculation module will be passed through after the optimization process of program sends actuating mechanism controls module, alarm module, display module and communication module to; After the actuating mechanism controls module receives the signal of self-decision and optimizing calculation module; The operating condition of decision relevant device: alarm module receives decision-making and optimizing calculation module signal; Whether decision reports to the police; Communication module receives decision-making and optimizing calculation module signal, realizes communicating by letter of micro controller system and main console desk: display module receives decision-making and optimizing calculation module signal, shows the information that receives in real time.
The actuating mechanism controls module; Comprise pump group control module and triple valve control module and corresponding valve control module; Wherein pump group control module provides the circuit of transition between micro controller system and the electric machine control contact; Utilize photoelectricity to isolate and guarantee that micro controller system is not impacted by foreign current: the aperture that the triple valve control module is regulated triple valve according to the PID module result calculated in the optimized Algorithm, the scope that triple valve outlet water temperature stability is being required: the valve control module is according to the circuit design characteristics, in conjunction with working as front pump group start-stop situation; The unlatching of valve in the decision pipeline, and the unlatching of air conditioned valve.
Display module receives decision-making and optimizing calculation module signal, shows sea temperature, triple valve temperature out in real time.
In the collecting sensor signal processing module; Sea temperature acquisition processing module, fresh water temperature acquisition processing module, pressure signal acquisition processing module, differential pressure signal acquisition processing module are all realized the collection of original signal through sensor; Comprise that specifically the temperature sensor that a) is installed in each bilge of boats and ships gathers the temperature in current ship's navigation waters; As an input parameter of decision-making and optimizing calculation module, link to each other with alarm module simultaneously; B) pressure sensor that is installed in each pipeline is gathered each line pressure; Result of a measurement offers decision-making and optimizing calculation module; C links to each other with alarm module simultaneously) differential pressure pick-up that is installed in the central cooler two ends of each cabin measures the differential pressure signal at intercooler two ends, as making a strategic decision and an input parameter of optimizing calculation module.
Alarm module receives decision-making and optimizing calculation module signal, reports to the police through the control of micro controller system internal processes, and the water outlet temperature exceeds range of temperatures requirement, breakdown of equipment and necessary information is reported to the police by the Single-chip Controlling programming control need report to the police the time.Communication module; Be responsible for the communication between central cooling control system and the boats and ships master control system; Standard communication is cooled off the system system with central authorities and the boats and ships master control system links together with crossing; Can monitor the operation conditions of central cooling system at main console desk, perhaps through main console desk control central cooling system.
