Description

The utility model relates to computer technology and can be used in control systems of various industrial facilities, including and in transport.

The life cycle of such highly reliable systems amounts to several tens of years. In a situation where the supply of backbone electronic components and the necessary software from foreign manufacturers every year becomes more and more not guaranteed, in particularly demanding applications it is necessary to reduce the dependence on the foreign element base and software.

In such systems, embedded computers with the AT96 bus in the Euromechanics 3U construct are widely used. An analogue is the S-AT96-FOX2 module ("Modern Automation Technologies", No. 2, 2001, pp. 56-65) manufactured by Lippert Automationstechnik GmbH. The module includes: a Geode microprocessor with a frequency of 300 MHz, RAM of 128 MB, a graphic controller with a volume of video RAM of 2 MB, one Ethernet 10 / 100Base-T interface, two USB interfaces, a flash memory for the ROM program, software controlled watchdog timer. Disks in CompactFlash format can be installed on the module. The control system can be equipped with I / O cards: AT96-COM8-1 8-channel RS-232C serial interface card with 16 byte FIFO; AT96-DIO16-2 digital input-output board with isolated input and output discrete signals; AT06-REL8-001 relay board; AT96-BCU-001 bus control and monitoring board.

The prototype of the module is the Fastwell CPC203 module (https://manualzz.com/doc/44426533/cpc203-cpu-card). The module uses a 32-bit microprocessor Geode GX1 300 MHz foreign production of AMD. The following devices are included in the module: system controller, 128 MB SDRAM RAM, boot flash memory with installed bootloader program (BIOS), 16 MB solid state disk (SSD), SVGA video controller with up to 4 MB video memory, two Ethernet 10 / 100Base-T interface, USB interface, two RS232C interfaces, AT-96 expansion bus, real-time clock with calendar, watchdog timer. Compatible operating systems for this module: already unsupported MS-DOS, Windows 2000, QNX, Linux.

A disadvantage of the known module is its poor performance.

The technical result from the use of a patentable utility model is to increase the performance of the control module.

The specified technical result is achieved by the control module for telemechanics systems, containing a microprocessor (MP) with a random access memory (RAM) connected to it, flash memory, a solid state drive (VT), read-only memory (ROM), non-volatile real-time clock with a calendar ( RTC), and containing a watchdog timer, Ethernet interface, USB interface, RS232C interface, AT-96 bus controller, and in which it is used as:

MP - 1890VM8YA 64-bit microprocessor with COMDIV architecture;

RAM - memory type DDR3;

ТН - mSATA SSD;

ROM - memory type EEPROM;

and which is equipped with an HDMI interface with electrostatic protection connected to the MP, a GPIO interface with galvanic isolation connected to the MP, and DC / DC converters of primary voltage 5 V to secondary supply voltages.

Since the patented utility model uses MP with a larger capacity (64-bit MP) and with a higher frequency (500 MHz), the module's performance is higher than that of the prototype module.

The utility model is a module in the constructive "Euromechanics" 3U, width 8HP.
