The closest in the set of essential features is the automated monitoring and diagnostics complex of the development of OJSC “Lead Production and Technical Enterprise“ Granit ”according to patent RU 2257604 C2, adopted as a prototype. The advantage of the prototype is the ability to create compact automated workstations for monitoring, diagnosing malfunctions and repairing a wide range of electronic devices.

The disadvantages of the known device are:

-lack of the ability to simultaneously collect digital-analog data;

-lack of wide possibilities for switching digital and analog signals from the control object;

- lack of a full range of measured electrical parameters.

The task the utility model is aimed at is the creation of a simple-to-use and compact device for the automated verification of digital-analog equipment.

The technical result from the implementation of the proposed technical solution is to reduce the complexity of the layout solution of the automated workstation for monitoring digital-to-analog equipment while increasing the level of automation of controlling parameters of electronic equipment and expanding the range of measured electrical parameters.

The problem is solved, and the technical result is achieved due to the fact that in the known control device containing a control computer, a digital input-output block, a pairing unit, a switch, a block of digital oscilloscopes, a block of arbitrary signal generators, a block of programmable power supplies connected together by a single a data and synchronization bus, an additional data collection unit, consisting of one or more modular data acquisition devices, and a multimeter unit, consisting of one or more modular mul timeters. Each block of digital input-output, block of digital oscilloscopes, block of arbitrary signal generators, block of programmable power supplies are made in the form of one or more modular devices. Each of the blocks is directly connected by the inputs and outputs with the inputs and outputs of the monitoring object and the lines of the relay switch, while the columns of the relay switch are connected with the inputs and outputs of the monitoring object. The interface unit is made in the form of two interconnected individual interface units, one of which is connected to the data and synchronization bus, the second to the computer’s PCI or PCI-E bus. In the memory of the control computer, a set of programs for managing a workstation is installed for various checks of objects of control, to create data for managing a workstation or to verify the correct functioning of a workstation.

Installing an additional data collection unit allows you to organize the simultaneous collection of digital-analog data, the simultaneous processing and conversion of data from a digital form to an analog form and vice versa. The installation of an additional multimeter unit allows you to generally get a full range of possible measured electrical parameters. A digital I / O unit in the form of one or more modular devices allows you to increase the number of digital I / O channels, simplify the hardware implementation of the device. The implementation of the block of arbitrary signal generators, the block of digital oscilloscopes, the block of programmable power supplies from modular devices allows you to simplify the manufacture of the device, its maintenance and repair, and also provides unification during expansion. Connecting each unit directly with inputs and outputs to the inputs and outputs of the monitoring object allows simplifying the connection of the monitoring object. Connecting each block with inputs and outputs to the lines of the relay switch, and columns of the relay switch to the inputs and outputs of the monitoring object allows switching input and output signals from the monitoring object with a significantly larger number of them than modular devices in any of the blocks. The implementation of the pairing unit in the form of two separate modules allows you to use a combined data bus and synchronization, which, in turn, reduces the complexity of manufacturing the device. Using a set of programs increases the level of automation of control of parameters of electronic equipment.
