O: its controlling mechanism of input signal (I) is described as follows:

When using remote control, the storage of programmable logic controller (PLC) or microcomputer controller is calculated, order is set, and regularly, functions such as (RANDOM) cooperates the utilization of I/O element at random, the drive motor device, control motor speed (v), displacement (d), the parameter of commutation time out (t), adjust it and change combination, grouping and setting, and programming uses reaching the requirement of the multi-purpose bed control of the present invention, but for following design standard is arranged security, reliability and the service life of guaranteeing control system:

Promptly reserve the durable standard and the scope of application of equipment, two additions are equivalent to limit constant (c), consider the duration of runs and number of times (f) again, if (v) want fast, then displacement (d) or commutation time out (t) must prolong the speed of motor.

As shown in figure 12, be the multi-purpose bed basic control circuit figure of the present invention, comprise: (1) switching declaration:

S1: power switch

S2: move a during operation simultaneously: manual selector switch, b: manually/not limit by the centre position

The system switch

S3, S4, S5: up limit switch

S6: set manually descending

S7: move a during operation simultaneously: up stroke selector switch, b: following row selecting switch, c: displacement limit

The system rate selection switch

S8:S9, S10: down stroke limit switch

The excitatory self-holding switch of L1:L

ML: motor coil

(2) running explanation:

A: manually part: S2 cuts to M, press S6 and selects descendingly, or it is up to press the S11 selection, with S14 cut to

The speed of setting is done the adjusting microinching displacement by S12, to touching S5 or S10 commutation travelling backwards.

B: automatic part: S2 is cut to A, and a bed body is parked in the centre position automatically, switches S7 and sets stroke, cuts

Change the S14 setting speed, cut fast TD and set time out, adjust TDA and set the duration of runs, open

Start from moving running, arrive the duration of runs, is parked in the centre position automatically.

Manufacturing cost is considered in the design of controller, can select simply, accurate or practical three kinds of control modes: (one) simple control: in the support displacement stroke, removal apparatus is fixed upper and lower limit switch, and installs

It is several to fixed inductive switch and known three speed control system modes that the section control is selected, and have manually

Or the function of regular running.(2) accurate control mode:

A: the stroke at main body both sides support 107 internal displacements is provided with the upper and lower limit switch and the position of making zero

Put the inductive switch of (in the level bed state).

B: manually control: mix up required speed, good direction press push button is promptly walked, decontrol and promptly stop,

Need to restore after running into that upper and lower limit switch is anxious and stopping and to go startup again.

C: paragraph control: (level bed state) orders about lift head 143 up with manual operation in the position of making zero

Or toward being displaced downwardly to the demand position, depress initial memory point M1, more up or toward being displaced downwardly to demand

Distance, depress and stop memory point (M2), the counting element of displacement monitoring device will be changed motor

The memory stores displacement (d) therebetween of 131 switching signals input control, and adjustment demand speed

Degree (v) reaches commutation time out (t), sets the duration of runs again, depress start button, then rise

Falling 143 will be in the displacement (d) of storage, press setting speed (v), the time out (t) that commutates,

Regular back and forth upper and lower moving (M1 ← → M2) till regularly removing.

D: STOCHASTIC CONTROL: store with the point of above-mentioned manual control that (M1 → M2) serve as that different storages are expanded on the basis

The point draw up circulation storage group G=(M1 → M2 → M3 → M4....Mn), wherein, cover a circulation,

Elevating lever is promptly got back to the position of making zero automatically, if again expand different circulation storage groups (G1, G2,

G3, G4 ... .Gn), the user can select group to exercise repetitive cycle operation arbitrarily, or

Depress random button, selecting different groups at random, exercise non-regularity the jumper connection running as

(G1 → G5 → G3 → G1 → G6 → ... .), up to regularly removing, revert to the level bed position.(3) practical control mode:

A: the fixing upper and lower limit switch of device in the support displacement, again installing can electronic accent move a pair of

(fractional motor is located at the position of making zero of level bed state to upper and lower inductive switch, with this point is

The heart drives inductive switch and is contained in terminal tooth bar and makes upper and lower symmetrical expression along a winning post and move),

This switch removes and is used for responding to the different magnetic code of each point on the winning post, the position of rising and falling when moving to demarcate accent

Put, other accepts lift head 143 shift rods and closely connects the induction action, moves and further limit it

Scope.

B: manually control: set demand speed, good direction press push button is promptly walked, decontrol and promptly stop, bump

Then stop to limit switch.

C: paragraph control: transfer move inductive switch to the displacement of demand (M1 → M2), mix up demand speed again,

Set the duration of runs, depress start button, then lift head 143 will be complied with in the displacement of demand

The speed of demand, regular repeat upper and lower moving (M1 ← → M2), up to regularly removing,

Return the level bed state.

D: STOCHASTIC CONTROL: programmable logic controller (PLC) input is through the motor speed of experiment layout

(v), rotate a second number (d), commutation time out (t) after the grouping allotment, is set its action

In proper order, as G=(M1 → M2 → M3 → M4 → M5 → M6), and expansion group number, G1=(M1-M6),

G2=(M7-M11) ... .G18, again according to the length of mobile standard divide at a high speed the group (G14,

G15, G16, G17, G18), the low speed group (G9, G10....G18), at a slow speed group (G1,

G2, G3 ... G18), could turn round as if the group that the setting different range should be selected to be fit to,

Otherwise starting failure represents to select wrong group (as short distance choosing high speed group), and each group finishes again

One circulation all can return dead-center position automatically, therefore when moving range is moved maximum to, depresses

Button can be selected single group, the regular cycle operation of indivedual speed groups, or indivedual speed group

Mix the running at random of speed group non-regularity etc., up to regularly removing.
