Abstract
The present invention is a kind of self-programming auto-running calculator industrial controller who is made up of counter G, self-compiling program governor circuit A, sampled data input interface circuit B and counter output interface circuit C.It can fully develop the counter potential function, utilizes counter G to realize reaching 24 hours time sequencing control more than four, has self-loopa simultaneously, intersects and circulate and 61 kinds of mathematics control function.Also can be used as detection record instrument required in the automatic control, and the batching data processing etc.It is cheap, and is simple to operate, easy to use.
Description
The invention belongs to automaton, especially a kind of counter industrial control unit (ICU) of self-compiling program self-operating.
Used in the past capacitance-resistance can only be done single time control along control device, motor delay controller and time controller, complicated in mechanical structure, and the student movement of can not counting is calculated and control.And computer-controlled time controlled system cost height needs special study application program, maintenance difficult.
The purpose of this invention is to provide a kind of abundant exploitation counter potential function, utilize counter, realize reaching more than four 24 hours time sequencing control, have self-loopa simultaneously, intersect circulation and add, subtract, 61 kinds of mathematics control function such as multiplication and division, logarithm, index, trigonometric function and infinitesimal analysis, cost is low, self-programming auto-running calculator industrial controller simple to operate, easy to use.
Industrial control unit (ICU) of the present invention is formed by counter G with self-compiling program governor circuit A, sampled data input interface circuit B and the counter output interface circuit C of counter G adjunction.
Below in conjunction with accompanying drawing this industrial control unit (ICU) is further described.
Fig. 1 is the structure calcspar of this industrial control unit (ICU).
Fig. 2 is the principle calcspar of this industrial control unit (ICU).
Fig. 3 is the circuit diagram of A.
Fig. 4 is the circuit diagram of B.
As shown in Figure 2, self-compiling program governor circuit A is made up of the oscillator Z of photoelectric coupling circuit L, code translator E, counter Y and the fixed frequency of the written-out program that send number and control counter output interface circuit C of control sampled data input interface circuit B.Sampled data input interface circuit B is made up of the analog to digital conversion circuit S that sensor H input signal is changed and decoding scheme I and figure place program distributor F, and its execution is controlled by circuit A.Counter output interface circuit C is made up of position control circuit W and digital-to-analog conversion control circuit K.It can realize the position control along control according to the memory function of giving the correct time of counter G; Also can be by the control criterion signal of D/A converting circuit K output 0～5MV or 0～5MA.
Self-compiling program governor circuit A can adopt simple relay circuit (as shown in Figure 3), utilizes relay J
