The technical solution of the utility model is; A kind of backwash high pressure filtering station controller comprises CAN communication module, AD modular converter, signal processing module, pressure sensor, 232 communication modules, core single-chip microcomputer, driver module, electromagnetic priority valve, Keysheet module and LCDs; CAN communication module, 232 communication modules, Keysheet module and LCDs are respectively by the core Single-chip Controlling; Pressure sensor connects signal processing module, is connected to the core single-chip microcomputer through the AD modular converter again; The core single-chip microcomputer is through driver module control electromagnetic priority valve.
Described a kind of backwash high pressure filtering station controller comprises that also one is connected the warning device on the core single-chip microcomputer through the I/O mouth.
The utility model advantage compared with prior art is:
(1) because the utility model adopts core Single-chip Controlling, type of drive, therefore, can control cleaning, realize low-cost, stable strong, easy to operate according to pressure, time-pressure, time three kinds of modes.Promptly under pressure control cleaning way, the pressure in the filter input channel and the pressure in the output channel are compared,, promptly start flushing process when pressure reduction surpasses the value of setting and is that to be higher than the time pressure of setting poor.Under pressure-time control mode, flushing process started after the circulation timei of setting.If within this time, surpassed pressure reduction, and this is that to be higher than the time pressure of setting poor, and then flushing process starts, and carries out backwash.Under time control cleaning way, flushing process was activated after the cycle that can set.This time is by minute being provided with.
(2) compatible good.The producer that produces electromagnetic priority valve at present is many, and the connection between each parts of the utility model need only be changed a plug, just can adapt to the technical parameter of each producer's electromagnetic priority valve, has greatly improved compatible performance.
Description of drawings
Accompanying drawing 1 is that the structure of the utility model connects sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1; A kind of backwash high pressure filtering station controller of the utility model comprises CAN communication module 1, AD modular converter 2, signal processing module 3, pressure sensor 4,232 communication modules 5, core single-chip microcomputer 6, driver module 7, electromagnetic priority valve 8, Keysheet module 9 and LCDs 10; CAN communication module 1,232 communication modules 5, Keysheet module 9 and LCDs 10 are controlled through core single-chip microcomputer 6 respectively; Pressure sensor 4 connects signal processing module 3, is connected to core single-chip microcomputer 6 through AD modular converter 2 again; Core single-chip microcomputer 6 is through driver module 7 control electromagnetic priority valves 8.
Described a kind of backwash high pressure filtering station controller comprises that also one is connected the warning device 12 on the core single-chip microcomputer 6 through I/O mouth 11.
In the present embodiment, CAN communication module 1 adopts the PCA82C250 integrated circuit to realize that CAN is the abbreviation of control area net (Controller Area Network), is a kind of fieldbus.The communication speed of CAN reaches as high as 10Mbit/s, and is suitable with the communication speed of full speed USB, and its transmission range can reach 10km farthest, and attachable equipment can reach 110 at most.AD modular converter 2 adopts 16 passages, and the professional chip of 10 precision comes the signal of telecommunication of pressure sensor 4 is carried out analog-to-digital conversion.Signal processing module 3 adopts the TLV2374 integrated circuit that the pressure signal that pressure sensor 4 collects is carried out signal condition, maintenance and amplification.What pressure sensor 4 adopted is intrinsic safety type specialty sensor, this sensor rated operational voltage DC12V, rated operational current 15mA, range 0～60MPa.In the present embodiment, adopt 4 pressure sensors 4.
In the present embodiment, core single-chip microcomputer 6 adopts 16 single-chip microcomputers of MC9S12 series of Freescale company.This series monolithic adopts the 5V power supply, and the bussing technique of 25MHz has the special-purpose communication module of abundant I/O module and Industry Control.Carry out the transmission of data through 232 communication modules 5 between core single-chip microcomputer 6 and the LCDs 10.232 communications are a kind of common serial communication modes.Driver module 7 is used to drive electromagnetic priority valve 8, behind core single-chip microcomputer 6 output switching signals, controls the unlatching or the closing motion of electromagnetic priority valve 8 through communication module 7.Keysheet module 9 adopts professional ZLG7290 integrated circuit, detects and transmits key value through the IIC communication mode.LCDs 10 can be real-time some status informations of demonstration filter station.Warning device 12 is realized the sound and light alarm caution through the flicker that pipes with light emitting diode of buzzer.
