Description

The utility model relates to automated control of parameters of electrical circuits and functional units of communication equipment. The device can be used as part of stationary and mobile repair complexes based on vehicles during technical maintenance (MOT) and repair of communication equipment products.

The disadvantages of the existing maintenance system and repair of communication equipment are:

low efficiency of work, a high probability of obtaining erroneous control results, which is associated with a large volume of control and measurement operations performed in manual mode;

the use of a large amount of workplace space to accommodate various types of general-purpose measuring instruments.

Known devices for automated control of electrical parameters of electronic equipment (CEA), used to control parameters on the basis of "norm-not norm." An example is a device for automated control of electrical parameters of REA (A.S. 1383306 USSR, MKI G05V 23/02), containing a block of stimulating signals, a switch, a block of meters, an object of control, a block of reference signals, a pairing unit, a common bus, sensors, control computer. A disadvantage of the known device for the automated control of REA parameters is the need for a computer as a control structural element, as well as the complexity of the system and circuit design of the device itself.

Closest to a utility model from the prior art and adopted as a prototype is a device for parameter control (A.S. 1513418 USSR, MKI G05B 23/02), containing an information output unit controlling a computer (UVM), a terminal, an address register block, two switches, a mode control unit, a synchronization unit, an input information register, a comparison unit, an analyzer unit, an output information register, a stimulating signal unit, a meter unit, and the inputs / outputs of the UVM are connected to the information output unit, the terminal, the output unit synchronization timing registers are connected to the inputs of mode control unit, the analyzer unit, block enabling signals, whose output is connected to a corresponding input of the switch. The disadvantage of the prototype is the complexity of the system and, accordingly, the circuit design, which leads to significant weight and dimensions of the device, making it difficult to use in conditions of limited free space of workplaces.

The technical result consists in simplifying the system and circuit design and reducing the mass and dimensions of the device.

The technical result is achieved by the fact that in the device for the automated control of the parameters of communication equipment containing a meter unit, an information output unit, a switch, a mode control unit, a stimulating signal unit, an additional control unit is implemented that implements the functions of a control unit, a synchronization unit, a comparison unit, and an analysis unit.

The analysis of the prior art made it possible to establish that analogues that are characterized by a combination of features that are identical to all the features of the claimed technical solution are absent, which indicates the compliance of the claimed device with the patentability condition of "novelty".

Due to the introduction of a set of essential distinguishing features into a known object, the claimed device for automated control of parameters, in comparison with the prototype, has a simpler system and circuit design, which allows it to be implemented with less weight and dimensions.

A device for automated control of the parameters of communication equipment, comprising a measuring unit 5, an information output unit 6, a switch 4, a mode control unit 1, a stimulating signal unit 3, the outputs of the stimulating signal unit 3 being connected to the corresponding inputs of the switch 4, characterized in that a monitoring unit is introduced 2, including the functions of the control computer, analyzer unit, comparison unit, and synchronization unit, and the outputs of the mode control unit 1 are connected to the inputs of the control unit 2, the outputs of which are connected to inputs of the block enabling signal 3, the switch 4 outputs connected to the inspected circuits and communications equipment to the input unit 5 meters, the outputs of which are connected to inputs of the control unit 2, outputs of which are connected to the control inputs of the switch 4 and the output information block 6.

The drawing (Fig. 1) shows a structural diagram of a device for automated control of communication equipment parameters.

The device operates as follows.

From the control unit mode 1 receives a control signal to enable the required control mode (which determines the type of equipment being tested, the type of parameter being monitored and its control values).

Control unit 2, taking into account the selected control mode, generates control digital codes of the address of the circuit under test and, if necessary (when monitoring passive parameters of electrical circuits), codes of types of stimulating signals received respectively at the control inputs of switch 4 and block of stimulating signals 3.

Block stimulating signals 3, generates stimulating signals in the form of measuring voltages to determine the passive parameters of electrical circuits (for example, resistances) supplied to the inputs of the switch 4.

Switch 4 performs alternating (in accordance with the address code) connection of the measuring voltages to the corresponding control points of the circuits being tested and (or) the transmission of primary signals of the measuring information about the values of the monitored parameters to the inputs of the meter 5.

In the block of meters 5, the primary analog signals of the measuring information are converted - their scaling, detection and filtering. The signals from the output of the block of meters 5, the parameters of which contain information about the values of the parameters of the object of control, are fed to the inputs of the ADC of the control unit 2.

The control unit 2 converts the measurement information into digital form, compares the determined parameters of the tested circuits with the control values and displays information about the results of the control in the information output unit 6.

In accordance with the proposed technical solution, a current prototype of a device for automated control of the parameters of communication equipment UAKP-M is implemented, the appearance of which is shown in FIG. 2.

UAKP-M (hereinafter referred to as the device) is intended for automated verification of parameters of electric circuits and functional units of three types of communication equipment.

The device provides control of the following parameters:

insulation resistance of electrical circuits;

transitional resistance (resistance of the metal connection between the terminal for grounding and the equipment instrument housings);

DC voltages of the secondary power source;

the magnitude and duration of the period of the sinusoidal signal and the sinusoidal signal with phase shift keying at the output of the modulator.

The device performs:

determination of values of controlled parameters;

comparison of values of monitored parameters with control values;

displaying information about the results of control on the LCD indicator.

During monitoring operations in the mode of checking the insulation resistance, the device automatically commutes the tested circuits.

In the transition resistance test mode, to increase the accuracy of determining the values of the monitored parameter, a preliminary operation is provided for determining the resistance values of the measuring cables for the subsequent correction of the control results.

In the mode of checking the voltage of the secondary power source, the device determines the value of the DC voltage of arbitrary polarity in the ranges:

1) from -1 V to +1 V and from +15 V to +50 V (from -50 V to -15 V);

2) from +1 V to +15 V (from -15 V to -1 V).

Range switching is carried out automatically by the device.

The control unit for the prototype device model is implemented on the basis of the LDM-K1986BE92QI-H debug board with the MDR32F9Q2I microcontroller. The information output unit is the MT-12864J-2YLG graphic LCD indicator. The microcontroller operates under the control of specialized software of the state registration certificate of a computer program: No. 2016613365 “Software for the automated control device of parameters UAKP-M (voltage monitoring mode of a secondary power source)”; №2016618814 "Software for automated control device parameters UAKP-M (insulation resistance control mode)"; No. 2016188841 “Software for automated control device parameters UAKP-M (transition resistance monitoring mode)”.

The controls (mode control unit) and the LCD indicator (information output unit) are located on the front panel of the device. Information for controlling the operation of the device, reference information (instructions to the operator), and also control results are displayed on the LCD indicator. In necessary cases, an additional sound alarm is provided.

The device controls are:

“POWER” button - turns on and off the power of the device;

“↓” and “↑” buttons - navigation buttons;

“SELECT / START” button - a button for selecting control objects, verification modes and operations / activating the verification mode, and starting operations.

The device is powered from a 220 V / 50 Hz network through an external adapter with an output voltage of 9 V (500 mA) or from an internal battery (in a prototype Li-ion 9 V, 780 mAh). When the device is powered from the network, the battery is recharged through a current-limiting resistor.

The small dimensions of the device 200 × 150 × 55 provide the possibility and convenience of its use as part of mobile repair complexes.
