interface ,etc. make in the integrated chip together, form an intact
microcomputer. One-chip computer apply controlled field to mainly, because it
have dependability high , small , price low , easy commercialization ,etc.
characteristic, therefore won extensive application in fields of automatic control
such as intellectual instrument and apparatus , real-time industrial control ,
intelligent terminal , communication equipment , navigation system , household
appliances ,etc.
It is that one kind can change the electric pulse signal into a
electromechanical component of angle displacement or line displacement to
walk into the electrical machinery, it is a kind of figure / angle converter that is
walked into the control system of the electrical machinery to mainly walk into
the controller in fact, power amplifier and walking into the electrical
machinery ,etc. make up . Walked into the controller to buffer the register , the
annular distributor, control logic and, overturn , control door ,etc. make up , can
change the pulse input into into an annular pulse , in order to control , walk into
electrical machinery , can carry on positive and negative to control. But
because walk into the controller circuit complicatedly. With high costs. Adopt
one-chip computer control , replace with software described above to walk into
the controller , make the circuit simple, with low costs, dependability increases
greatly, change the control scheme of walking into the electrical machinery
flexibly , do not need logical circuit to make up the time sequence generator .
Software programming very flexible to produce , walk into electrical machinery
excitation array come , control various operation way to walk into electrical
machinery and can realize one machine control many sets of electrical
machinery while being different kinds of. It is easy to realize to offer the flexible
control means and improving the precision of controlling to complicated and
tedious control, demonstrate the superiority that the computer controls
especially in this system even more.
Design , adopt , insult male genital 16 one-chip computer SPCE061A to
walk into electrical machinery control originally, square wave with time
sequence as the control signal of walking into the electrical machinery through
what IO mouth is outputted, the signal drives and walks into the electrical
machinery through the chip L298N; Meanwhile , come state in electrical
machinery go on , control with keyboard of 4X4 , in charge of rotational speed
to reveal electrical machinery with number, adopt 74LS164 urge as 4 single
number display that in charge of , from the input signal of the one-chip
computer; Utilize the pronunciation function of insulting the open one-chip
computer to report the rotational speed of the electrical machinery.
