The technical result of the invention is to expand the functionality, increase reliability, improve maintainability. The complex contains workstations and servers connected through a local area network Ethernet and based on personal electronic computers (PCs), as well as controllers and functional modules. Functional (MF) programmable logic integrated circuits (FPGAs) built into each module support the “flashing” of almost any signal processing and control algorithms that are adequate to the tasks that the designer assigns to this module. There are three options for building systems based on the complex: centralized management; local management; distributed management. In all three variants, the central processor module (under software control) performs initial configuration of functional modules, exchange of information, and control and diagnostics of software and hardware.

The main differences between the PAK and the selected analogue are that the service monitor of communications CMS 50/52/54 was used as the main control and measuring center, which made it possible to directly control the parameters of radio stations with an output power of up to 50 W using the direct measurement method masking - made it possible to control the passage in the PC transceiver path not only of a speech (analog) signal, but also of a digital sequence in the technical masking mode speech.

The technical result of the proposed utility model is to provide automated control of the parameters of radio stations by direct measurement.

The operating mode of the radio station, measuring instruments and automated TPs are controlled by means of a PC using the software developed for this PAK.

In the drawing, fig. 1 is a diagram of a hardware-software complex for monitoring parameters of radio stations R-168-0.5U. The hardware-software complex for monitoring the parameters of radio stations R-168-0.5U consists of the tested radio station 1, a service monitor of communication equipment 2, an interface converter 3, a transition device 4, a signal shaper of technical masking 5, a PC 6, a printer 7, a current monitoring device, and voltage 8, controlled power supply 9.

The hardware-software complex for monitoring the parameters of R-168-0.5U radio stations works as follows: the radio station under test (1 Fig. 1) is connected to a controlled device through a current and voltage control device (8 Fig. 1) and a transition device (4 Fig. 1) a power source (9 Fig. 1) and a service monitor for communications (2 Fig. 1). When starting the software (software) installed on the PC (6 Fig. 1), the serial number of the radio station (PC) is entered. Further, the control of the parameters of the checked radio station passes automatically under the control of the software developed for the software and hardware complex for monitoring the parameters of the radio stations.

The parameters of the radio stations are controlled at three levels of supply voltage, normalized by the technical conditions: nominal, maximum and minimum. The indicated voltage levels are generated by a controlled power source. The values of the supply voltage and the current consumed by the radio stations are recorded by the current and voltage control device, and transmitted to the PC.

The control of switching the operating modes of radio stations is carried out by a PC through a transition device.

The formation of the testing signals and the measurement of the parameters of the tested radio station is carried out by a service communication monitor connected via an interface converter (3 Fig. 1) to a PC, where the values of the measured parameters are transmitted.

In the control mode of the parameters of the radio station when the latter operates in the mode of technical masking of speech, the testing signals from the shaper of the technical masking signal (5 Fig. 1) are input to the external modulation input of the service monitor of communication facilities.

In the PC, the measurement results of the parameters of the radio station are processed and a test report is generated, which is displayed through the printer (7 Fig. 1).
