Embodiment

Below in conjunction with Figure of description the present invention is described further.

Like Fig. 1, shown in 2, a kind of slice ice machine control system comprises ice maker, control device, display device.Said 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.At first send instruction by control box 8; Start compressor 4; Refrigeration system through condenser 5, reservoir 7, device for drying and filtering 10, expansion valve 3 form is given birth to refrigeration; Supply water by brine pump that is assemblied in water tank 14 13 and the refrigeration system of water pump 12 again, form the state of freezing, be cut into the borneol of rule again by reductor 2 devices to ice machine.As shown in Figure 3; Said control device is industrial computer and PLC; Said display device is the touch-screen that is connected with industrial computer; Embed the embedded configuration software of MCGS in the said industrial computer operating system, the configuration software programming code signal of industrial computer imports the PLC connection into through being connected with the RS-232C interface of PLC; The power of compressor inlet wire is connected with electrothermal relay FR1 with relay K M1, and the electric power incoming line of reductor is connected with electrothermal relay FR2 with relay K M2, and said relay K M1, relay K M2 are controlled by said PLC.

Ice machine open and close machine principle:

Among the PLC of the present invention, code POA is a slice ice machine start input point, and code POB is the shutdown input point, and all is normal the battle.After clicking touch-screen start button, the configuration software programming code signal of industrial computer imports PLC input point POA into through 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; Through the PLC internal processor; Transmit signal to output point; With the input point P41 conducting that relay K M2 is connected with electrothermal relay FR2, the P42 that is connected with electrothermal relay with the water circulating pump relay begins conducting, so the reductor of ice machine and water circulating pump begin startup work; Set according to the PLC inside programming, delay time after 30 seconds, begin conducting with the input point P40 that electrothermal relay FR1 is connected with relay K M1, then compressor starts startup work, the ice machine work that formally brings into operation at this moment.Shutdown is roughly the same with the start principle of work, repeats no more at this.

The fault display device of control system comprises the first sensor that is used for the monitoring compressor high-pressure side, second sensor of monitoring compressor low pressure end, the 3rd sensor of monitoring compressor oil level, the four-sensor of monitoring compressor water level, the 5th sensor of monitoring compressor oil pressure, the 6th sensor of monitoring compressor electric power incoming line overload, the 7th sensor of monitoring reductor electric power incoming line overload, the 8th sensor of monitoring power phase; Said first sensor to the eight sensors all are connected with said PLC, and through industrial computer monitoring information are presented on the touch-screen.First sensor is connected with the P00 input point of PLC; Second sensor is connected with the P01 input point of PLC; The 3rd sensor is connected with the P02 input point of PLC, and four-sensor is connected with the P03 input point of PLC, and the 6th sensor is connected with the P05 input point of PLC; The 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 input of the P00 of PLC point no signal, PLC is passed to industrial computer with signal, and industrial computer carries out analyzing and processing to signal, and on touch-screen, shows the compressor high voltage fault, and guides operating personnel to check condensation fan and cleaning condenser; When the input of the P01 of PLC point no signal, PLC is passed to industrial computer with signal, and industrial computer carries out analyzing and processing to signal; And on touch-screen, show the compressor low voltage failure; Whether and guide operating personnel to check and intake in the ice bucket normally, whether normal, whether check system has leakage point to exist if falling ice; When the some no signal input of the P02 of PLC input, PLC is passed to industrial computer with signal, and industrial computer carries out analyzing and processing to signal, and on touch-screen, shows compressor and freeze machine oil fault, and guides operating personnel whether to check oil starvation; In like manner the no input signal of the P03 of PLC point then shows the water system fault; The no input signal of P04 point of PLC then shows to advance electric fault; The no input signal of P05 point of PLC then shows the overload of compressor fault; The no input signal of P06 point of PLC then shows the reductor overload fault; The no input signal of P07 point of PLC then shows cooling-water pump or cooling fan overload fault.

The principle of the fault Presentation Function of system:

Present embodiment describes 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 anodal PLC input point P00 that inserts of the signal wire of Hi pilot, the signal wire negative pole inserts PLC input point 24V; According to the PLC inside programming, input point P00 is normally closed point, because the top pressure numerical value of Hi pilot is 25bar; When high pressure surpassed 25bar when ice machine work moves, input point P00 transferred normal battle to by normally closed point, transforms through the PLC internal processes; The PLC processor sends signal to output point P43, and malfunction indicator lamp is glittering, and input point P40 breaks off; Thereby relay K M and electrothermal relay FR1 break off, and ice machine is shut down; And the PLC program is imported industrial computer into by the RS-232C interface, so the touch-screen window can show failure cause and code.Other fault Presentation Functions are roughly the same with the principle of work of high voltage protective function, repeat no more at this.

The present invention adopts embedded integrated industrial computer, and master unit is that a cover is the high-performance embedded integrated touch-screen of core (dominant frequency 400MHz) with embedded type low-power consumption CPU.7 inches high brightness TFT LCDs (resolution 800 * 480) have been adopted in this product design, and four-wire resistance type touch screen (resolution 1024 * 1024) has also been pre-installed the embedded configuration software of MCGS simultaneously.The embedded configuration software of MCGS is mainly accomplished collection and the detection of field data, the processing and the control of front end data.The embedded configuration software of MCGS combines with other related hardware equipment, can be quick, develop the various collection in worksite that are used for easily, the equipment of data processing and control.Like various intelligence instruments that can flexible configurations, data acquisition module, specialized equipments such as recording instrument without paper, unattended collection in worksite station, man-machine interface.The embedded integrated industrial computer of TPC7062KS has been realized the effective monitoring to ice machine PLC electrical control input point; Thereby demonstrate ice machine work operation conditions intuitively; Therefore, for the unlatching of machine, stop, debugging, detection, fault analysis, operate easier, direct, accurate.
