Small Control Systems


Draft, implementation and repairs of electronics


Design and realization of electronics

 Customer electronics.
 I suggest small electronic devices and ensure their implementation. It is the following routine:

-the automation of process equipment
-measurement and control systems
"Internet of things"

Automation of process equipment
Machine control is designed and delivered according to customer requirements.
Brand programmable and safety relays, sensors, servo drives are used.
Measurement and control systems
Applications with 16 and 32-bit DSC Microchip ,formerly with 
ADC controllers Analog Devices Physical values- Using of sensors
Freescale MPXA4250A, MPXH6250A
ADXL213, ADXL203, ADXL345
SMT160-30, DS1820, KTY81, Pt100, termocouples(type J,K)
Position - incremental sensors, optical barriers,...
Vedle direct analog inputs  you can for analog measurements  advantageously use serially controlled chips, in particular  Σ-Δ A/D converters:  for accurate process measurements(R,p,T)  ADS1248, for AC values (U,I,P,cosf,f)   MSP430AFE233 .
Driving of DC motors BL  and brush, stepping motors,
use of frequency converters for induction motors .

Internet of things
ESP pack ESP pack ESP32a ESP32bOne of the cheapest and most used IoT modules on the market, Espressif WROOM32 serves as a Wifi station or access point with an IP address and DNS, DHCP, and so on. They have a 32-bit processor that can perform countless functions, from simple logic to sophisticated controllers.

 Application examples:
Remote control drive of carriages with videocameras - Ibos, Czech Budweis
Modernization of control of presses of plastics -JP plastic, Sudoměřice by Tabor
