DEVICE FOR AUTOMATION OF THE INVESTIGATION timekeeping time-consuming operation machining parts ENGINEERING

摘要

The invention relates to devices for carrying out this type of observation, wherein the individual elements are studied machining process engineering parts, namely, registration, display and record the execution time of processing operations. The technical problem stated utility model, namely, the automation of timing, is achieved in that the device comprises a plastic housing, in which fixed block seven segment display, consisting of four seven-segment indicators and LED visually separating the indicators into two groups of two LEDs in each , an information display unit that displays the data on the performed process step, the data input unit, configured as a keyboard shestnadtsatiknopochnoy, two keys and two light odioda, via which the switching on and off timing of a processing operation, and display the current status of the device, wherein the control unit is based on eight bit microcontroller comprising a program and data memory, universal eight-bit bidirectional input-output ports, an interrupt controller, a universal synchronous-asynchronous receiver-transmitter, timers, counters; the apparatus further comprises an interface converter that is used to connect to a personal computer and a block of non-volatile memory containing data on the technological operations, the blocks seven segment display, an information display, data input, two buttons and two LEDs, and the interface units converter and a non-volatile memory connected to the input-output port eight bit microcontroller.
