Description

Technical field

The invention relates to measuring devices for detecting faults in electrical circuits in traction rolling stock.

State of the art

A digital multimeter with automatic measurement function selection is known from the prior art, which contains an input terminal with three contacts for connecting a measurement object to them, a fast analog-to-digital converter, an analysis and processing microprocessor and a display connected in series, as well as a software-controlled power supply. The power source is configured to supply alternating or direct current to the measurement object. The power supply is connected to the microprocessor and to the first contact of the terminal and, through one resistance, to the analog-to-digital converter. An analog-to-digital converter is connected through a voltage divider with a group of resistances to the second contact of the terminal and directly to the third contact of the terminal, connected to the second contact of the terminal through another resistance, configured to apply the measured current to it through the second and third contacts of the terminal, the first and second contacts which are made with the possibility of connecting to them an object from the group: resistor, capacitor, inductor, diode. The microprocessor is configured to repeatedly interrogate the presence, determine the value and polarity of the voltage on the terminal contacts, compare with the threshold value and determine the type of the measured object from the above group. The microprocessor is equipped with means for controlling the type of voltage supplied by the power source, controlling the analog-to-digital converter switch to select the measurement method and range using the appropriate resistance from the voltage divider (RU 2482501, C2, G01R 15/12, publication date 10/27/2010).

The disadvantage of this device is the lack of the ability to promptly detect faults in the input signals, as a result, an increase in the downtime of locomotives for scheduled and unscheduled types of repairs, which in turn incurs additional financial losses for the enterprise.

A compact multimeter is known with simultaneous indexing of several physical quantities reflecting the electrical parameters of the research object, including a connecting device, an electronic circuit and at least one display, characterized in that the electronic circuit and the display are configured to simultaneously display at least three electrical parameters of the research object by the multimeter: electrical resistance, inductance, electrical capacitance, despite the fact that the display has at least three information zones, respectively, each of which is assigned the indication of its specific parameter, and the distance between the centers of such zones does not exceed 20 cm (RU 162521, U1, G01R 15/00 , publication date 06/10/2016).

The disadvantage of this device is the lack of the ability to promptly detect faults in the input signals, as a result, an increase in the downtime of locomotives for scheduled and unscheduled types of repairs, which in turn incurs additional financial losses for the enterprise.

As the closest analogue, a built-in digital multimeter is adopted that reads in time, stores and transmits measurement results from the power cable of power-consuming equipment, which is characterized by the function of diagnosing the electrical network to power-consuming equipment, for current and voltage, the presence of a built-in digital ammeter and a built-in digital voltmeter, characterized in that: it is built into the power supply network of electrical equipment, for operation, on a permanent basis, in the case of embedding inside (in the cavity) of electrical equipment, electrical appliances and electrical appliances, it does not have its own housing, if it is attached to the housing, or in a gap in the open power cable of power-consuming equipment , has its own body (RU 2020107372, A, E01H 8/00, publication date 08/20/2021).

The disadvantage of the closest analogue is the lack of the possibility of embedding inside (into the cavity) the tested circuits, as well as the need for subsequent analysis of the recorded parameters.

The technical problem of the claimed invention is to overcome the technical disadvantages inherent in analogues, which leads to the need to create an indicator for monitoring input signals on control units on traction rolling stock, with the ability to detect faults in input signals, which reduces the time for scheduled repairs of traction rolling stock.

Implementation of the invention

The input signals control indicator on the control units is used when carrying out scheduled and unscheduled types of repairs of traction rolling stock equipped with complexes of means for collecting and recording data of the KPD-3P (KPD-3PA) series. The device works as follows:

On traction rolling stock, an indicator for monitoring input signals is being installed. After connecting, it is necessary to turn on the power of the complex of means for collecting and recording data of the KPD-3P (KPD-3PA) series. As confirmation of the presence of voltage, the "NETWORK" LED, connected to contacts A12 and A13, lights up. After checking the presence of voltage, the EPK-150 key is turned on and the presence of the EPK1 signal is monitored, which indicates the presence of power on the electromagnet coil (LED connected to contacts B8 and A9). To check the lights of automatic locomotive signaling signals (ALSN), a loop is connected to simulate ALSN signals. On the front panel of the indicator (by lit LEDs "Z", "Zh", "KZh", "K", "B", connected to contacts B4, B3, B2, B1, B9, respectively, and the common contact A3, as well as the indication of signals "IF", connected to contact B 6 and A9), the compliance of the supplied and received ALSN codes is monitored. With the involvement of service personnel, the path and speed sensors (DPS-U) are dismantled with their subsequent scrolling. By the LEDs "DPS-1-1" (contacts C13 and C12), "DPS-1-2" (contacts C13 and SP), "DPS-2-1" (contacts C13 and C8) and "DPS-2-2 ” (contacts C13 and C7) the performance of each of the sensor channels is evaluated.
