Abstract
In recent years, industrial production is fast growing, much industrial production needs accurate timing to control production. In order to save the energy and facilitate the control and management of industrial production , need a kind of device urgently, i.e. the high-accuracy time-recorder of many ways. High-accuracy time-recorder each function module of many ways is successively: Circuit of the power , control circuit of the button (PT2262 code launches the circuit and PT2272 decipher and receives the circuit), AT89C51 one-chip computer is restored to the throne in the circuit, AT89C51 one-chip computer systematic control circuit , CD4511 decipher urge circuit, Select the circuit in 74LS138 location. (7407 or MC1413 urge the number to be in charge of revealing ).
This text introduce AT89C51 one-chip computer realize high-accuracy many way design of time-recorder in detail.
Key words：Time-recorder AT89C51 one-chip computer High-accuracy Industrial production dynamically Scan and display
