【正文】 t need for obtaining the resources in the tiny controller but installing exterior memory a machine or exterior in fixed time a machine. In addition to tiny controller outside, only have a little amount of zero parts performance some like output, importation, type ratio importation, show a circumstance of connect the and continuous movement etc. function. Use inner part memory alone, we can control a current of air system which has 48 steps, but if use a more simple system, will attain 60 steps. The controller bees not to use PLC language, but use one more simple of with intuition of structure. Make use of electricity system, our items applied a same technique, but our designs be getting more direct in the meantime. A kind of very simple machine language can the one who let design use 4 or 5 byte definition a step all structure posing. This will see how experience that he use controller is .Although this kind of controller can39。s top to circulate 1 to imitate procedure to look for a logical mistake together say of similar, new of plait the distance allow an each one step suddenly of the structure be partition. The sequence is alone define, but each one step suddenly be carry by the input and output to describe. 7. Conclusion This kind of controller39。from four active machines. The active machine A, B and C are double and only the D be doubly a list. Square one, the active machine A starts circulate, and keep in a particular position until a be over of circulation, such as figure 5 show it can make sure some one object of under one sport. The second step, was A to plete it of work after, the active machine C is together with the B start together many creation electric current a turn possibly, and be subjected to the restriction of B movement speed, but the B speed be lived a petal management by a control of fluxion. B and C is work together of active machine of example, be the B slowly pushes an object of time, the C sometimes then repeats it of work. The third step, be the position time that the B arrives an end, the C is immediately stop it of the circulation exercise and return to the position of beginning. The active machine D that the electric current that the exploitation return work together with return of the C works together. The fourth step, the active machine D quickly goes back and forth a return to exercise once. The D can act as a tool, the superficial dozen that is on the object hole. When the D returns to the position time of beginning, AN and B also return in the meantime and this be the fifth step. Diagram 6 showed program design the first part. We know together as all movements of each step. (A+) mean that the active machine A pushes forward, but(A) means to return to the position of beginning. Sport of the simultaneous with is together fold to add in the same step. This system totally has five steps. Diagram 5 circulate with 6 systems for express clear of described all sequences. Make use of them, we can design with the essential logic language whole of control circuit. But now return it not just an integrity of system, because it is still in need of some assistance facilities, .(diagram in show) Circulate to the end of procedure, these assistance facilitieses are very important, because they can make the circuit have more functions. They win the most important is a conjunction in eachly the one step suddenly of parallel circuit. That circuit can stop a sequence and change the appearance of active machine into a particular position at any time. It can heavy system or cope with an urgent circumstance. Diagram 7 with 8 what to shows be some results that will take place under the sistuation that have no usage controller. These photographs are the electricity charts which controls circuit, include sensor, control key and give or get an electric shock of live petal book. Moreover some assistance facilities also include in this system, the for example automatic machine/ hand moves to adjust to control a machine, they can make system continuous of circulating work。t carry out instruction, will appear a certain movement again a
