Embodiment
Below in conjunction with Figure of description, the invention will be further described.
As shown in Figure 1, 2, a kind of slice ice machine control system, comprises ice maker, control device, display device.Described ice maker comprises underframe 9, ice machine 1, compressor 4, reductor 2, expansion valve 3, condenser 5, condensation fan 6, reservoir 7, control box 8, device for drying and filtering 10, oil separator 11, water pump 12, brine pump 13, water tank 14.First instruction is sent by control box 8, start compressor 4, through the raw refrigeration of refrigeration system that condenser 5, reservoir 7, device for drying and filtering 10, expansion valve 3 are formed, supply water by being assemblied in the brine pump 13 of water tank 14 and water pump 12 refrigeration system to ice machine again, form icing condition, then be cut into the borneol of rule by reductor 2 device.As shown in Figure 3, described control device is industrial computer and PLC, described display device is the touch-screen be connected with industrial computer, embed MCGS Embedded Configuration Software in described industrial computer operating system, the configuration Soft-ware programme code signal of industrial computer imports PLC into connect by being connected with the RS-232C interface of PLC; The electric power incoming line of compressor is connected with relay K M1 and electrothermal relay FR1, and the electric power incoming line of reductor is connected with relay K M2 and electrothermal relay FR2, and described relay K M1, relay K M2 are controlled by described PLC.
Ice machine open and close machine principle:
In PLC of the present invention, code POA is slice ice machine start input point, and code POB is shutdown input point, and is all normal battle.When point touching screen starting key after, the configuration Soft-ware programme code signal of industrial computer imports PLC input point POA into by being connected with the RS-232C interface of PLC, by PLC programmed control POA point by often open transfer to normally closed, the conducting of POA point; By PLC internal processor, to output point transmission signal, the input point P41 conducting be connected with relay K M2 and electrothermal relay FR2, the P42 be connected with water circulating pump relay and electrothermal relay starts conducting, so the reductor of ice machine and water circulating pump start to start work; According to the setting of PLC inside programming, time delay is after 30 seconds, and the input point P40 be connected with relay K M1 and electrothermal relay FR1 starts conducting, so compressor starts startup work, now ice machine formally brings into operation work.Shutdown is roughly the same with start principle of work, does not repeat them here.
The fault display device of control system comprises the first sensor for monitoring compressor high-pressure side, second sensor of monitoring compressor low pressure end, 3rd sensor of monitoring compressor oil level, the four-sensor of monitoring compressor water level, 5th sensor of monitoring compressor oil pressure, 6th sensor of monitoring compressor electric power incoming line overload, 7th sensor of monitoring reductor electric power incoming line overload, 8th sensor of monitoring power phase, described first sensor is all connected with described PLC to the 8th sensor, and by industrial computer by monitoring information display on the touchscreen.First sensor is connected with the P00 input point of PLC, second sensor is connected with the P01 input point of PLC, 3rd sensor is connected with the P02 input point of PLC, four-sensor is connected with the P03 input point of PLC, 6th sensor is connected with the P05 input point of PLC, 7th sensor is connected with the P06 input point of PLC, and the 8th sensor is connected with the P04 input point of PLC.When the P00 point no signal of PLC inputs, PLC is by signal transmission to industrial computer, and industrial computer carries out analyzing and processing to signal, and shows compressor high voltage fault on the touchscreen, and guides operating personnel to check condensation fan and cleaning condenser; When the P01 point no signal of PLC inputs, PLC is by signal transmission to industrial computer, and industrial computer carries out analyzing and processing to signal, and show compressor low voltage failure on the touchscreen, whether and guide operating personnel to check in ice bucket and intake normally, whether normally fall ice, whether check system has leakage point to exist; When the some no signal input that the P02 of PLC inputs, PLC is by signal transmission to industrial computer, and industrial computer carries out analyzing and processing to signal, and shows compressor and freeze machine oil fault on the touchscreen, and guides operating personnel to check whether oil starvation; In like manner the P03 point of PLC is without input signal, then show water system fault; The P04 point of PLC without input signal, then shows into electric fault; The P05 point of PLC without input signal, then shows overload of compressor fault; The P06 point of PLC without input signal, then shows reductor overload fault; The P07 point of PLC without input signal, then shows cooling-water pump or cooling fan overload fault.
The principle of the malfunction coefficient function of system:
The present embodiment is described with compressor high voltage protective function.The sensing element of Hi pilot is contacted with compressor air-discharging pipeline (high-pressure side), thus sensing and control high-pressure side pressure; The signal wire positive pole access PLC input point P00 of Hi pilot, signal wire negative pole access PLC input point 24V; According to PLC inside programming, input point P00 is normally closed point, top pressure numerical value due to Hi pilot is 25bar, and when when ice machine work runs, high pressure is more than 25bar, input point P00 transfers normal battle to by normally closed point, transformed by PLC internal processes, PLC processor sends signal to output point P43, and malfunction indicator lamp is glittering, and input point P40 disconnects, thus relay K M and electrothermal relay FR1 disconnects, ice machine is shut down; And PLC program imports industrial computer into by RS-232C interface, so touch-screen window can show failure cause and code.Other malfunction coefficient functions are roughly the same with the principle of work of high voltage protective function, do not repeat them here.
The present invention adopts built-in type integrated industrial control computer, and master unit is a set of with the high-performance embedded integrated touch screen of embedded type low-power consumption CPU for core (dominant frequency 400MHz).This product design have employed 7 inches of high brightness TFT LCDs (resolution 800 × 480), and four-wire resistance type touch screen (resolution 1024 × 1024), has also pre-installed MCGS Embedded Configuration Software simultaneously.MCGS Embedded Configuration Software mainly completes the collection of field data and detection, the process of front end data and control.MCGS Embedded Configuration Software is combined with other relevant hardware devices, can be quick, develops various for collection in worksite easily, the equipment of data processing and control.As various can the intelligent instrument of flexible configurations, data acquisition module, the specialized equipments such as recording instrument without paper, unattended collection in worksite station, man-machine interface.TPC7062KS built-in type integrated industrial control computer achieves the effective monitoring to ice machine PLC electrical control input point, thus demonstrate ice machine work operation conditions intuitively, therefore, for the unlatching of machine, stopping, debugging, detection, fault analysis, operate easier, direct, accurate.
