Abstract
The multicooker design, structure and purpose of its main parts, the electrical circuit and the control system which includes sensor elements (sensors of pressure and temperature) are considered. The control unit in it is executed on the basis of 8-bit microcontroller MN15G1601 from PANASONIC SEMICONDUCTOR. The microcontroller read out a state of buttons of the keypad on the control panel and under the given program controls operation of multicooker and its elements. The structural diagram for automation of researches and tests of multicooker is offered. The choice of the basic microcontroller and circuit components is carried out. The structural diagram includes the following elements: object of research - multicooker with support of functions of different modes of cooking under pressure; the sensors D1 - D4 (pressure, temperature of the bottom and walls of a bowl of multicooker and pressure in the middle of the devices); the normalizing amplifiers P1- P4; the four-channel switchboard of analog signals of type КР590КИ6; the analog-digital converter (АDC) of type К1113ПВ1; the microcontroller 1816ВЕ51 (МК51) containing built-in clock generator, storage of commands and data, built-in 4 ports and a serial communication channel; comparators K1- K4 of type К554СА3, which outputs combine on "OR" with output signals from microcontroller port; communicating devices with object ПЗО1– ПЗО4 which, through the actuators of the power device, interact with the object of research and set the mode of its research or testing. Through serial interface RS232C the circuit is connected with a personal computer which can change modes of researches or tests, and also to accept, save, reflect and document results of researches or tests. The developed circuit and algorithm of its operation allow to automate technological process of researches of operation modes of multicookers, to reduce duration of their carrying out, to raise accuracy of measurements, and to lower their cost.
