Further, it is typically to have multiple work chambers for the bag filter of off-line type work, and each working bin
Room is required for a poppet and corresponding multiple pulse valves, and it (is typically a work thus to need the quantity for work chamber
Make bin and correspond to a poppet) it is configured, the poppet in corresponding foregoing parameter item is several and needs to every
The quantity of pulse valve in a work chamber is configured, and the group pulse in corresponding foregoing parameter item is several.For example, such as
Fruit is 3 by the several corresponding parameter values of poppet that function button and rotary encoder are set, then shows there are 3 work chambers
And the quantity of poppet is 3, if the several corresponding parameter values of group pulse set by function button and rotary encoder
It is 2, then the quantity for showing pulse valve in each work chamber is 2.It is further as a result, for solenoid valve control shown in fig. 5
Terminals JX15 processed, wherein, it is exactly the 1st work chamber that (or from right to left) it is corresponding, which to play the 1st terminals, from left to right
In poppet control terminals, and it is exactly 2 pulse valve controls in the 1st work chamber that the 2nd and the 3rd terminals are corresponding
Terminals processed；It is exactly poppet control terminals in the 2nd work chamber that 4th terminals are corresponding, and the 5th and the 6th
It is exactly 2 pulse valves control terminals in the 2nd work chamber that terminals are corresponding；Corresponding 7th terminals are exactly the 3rd
In a work chamber poppet control terminals, and the 8th and the 9th terminals it is corresponding be exactly in the 3rd work chamber 2
A pulse valve controls terminals.Although solenoid valve control terminals JX15, which has in 10 terminals, has only used 9, this 10 connect
Line end disclosure satisfy that this set requirement.It can thus be seen that solenoid valve control terminals be used as poppet control terminals and
It is the 1st poppet control terminals, the 1st successively from left to right or from right to left that the distribution relation of pulse valve control terminals, which is,
The corresponding M pulse valve control terminals of poppet control terminals, the 2nd poppet control terminals, the control of the 2nd poppet connect
The corresponding M pulse valve control terminals of line end, until N poppets control terminals, N poppets control terminals correspond to
M pulse valve control terminals, wherein N be the several corresponding parameter values of poppet, M be the several corresponding parameters of group pulse
Value, and meet the sum that N × M is less than or equal to solenoid valve control terminals, otherwise and group pulse several to poppet is several
The setting of parameter value will be set in vain.
Further, it is also necessary to operating time and mutual sequential relationship to each poppet and pulse valve into

After the pulse width of the last one poppet, if necessary to cycle from the first poppet start to work, then just need through
A time interval is crossed, this time interval is exactly period distances, which reflects when all solenoid valve control ends
Need how long to enter next work period after completing a work period.
In addition, pulse width item is 1-9999 by the range that 48 segment numeral pipes are shown, corresponding parameter value is 0.01 second-
99.99 seconds；For pulse spacing, to carry arteries and veins interval, interventricular septum item by the range that 48 segment numeral pipes are shown be 1-9999,
