Description

The field of technology.

The utility model relates to the field of energy, electrical engineering and automation and can be used to build automated control systems and technological processes of power plants.

State of the art

General technical requirements of national standards are presented to the operability of equipment that provides maintenance modes for software and hardware systems of industrial control systems.

There is a well-known test bench for analog and discrete blocks SPAB-M of a complex of technical and software tools of increased reliability (KTPS-PN). The stand refers to the means of functional and parametric control of analog and discrete blocks of a complex of technical and software tools of increased reliability during their manufacture by the production and during maintenance during operation at the facility.

KTPS-PN performs the functions of monitoring technological parameters and controlling equipment of technological systems in accordance with the algorithms specified in KTPS-PN.

In the KTPS-PN complexes, the input (measurement of values) of analog signals, the input of discrete signals that determine the state of the equipment and technological processes of the NPP power unit, the logical processing, the output of control and signaling commands of the KTPS-PN cabinets takes place.

SPAB-M stand does not participate in the control and management of technological processes.

The stand provides the following functions:

- power supply of controlled units (KB);

- functional check and control of design parameters;

- KB setting;

- storage and processing of control results;

- documentation.

The stand consists of a housing, a contact node with harnesses, a communication cable with a computer, a network cable and adapters to provide test modes for blocks of various types. Inside the stand housing are: the module of discrete signals MDS, the module of analog signals of the MAC, the power supply unit BPS2.

To check the analog blocks, a calibrated calibrator is used - a standardized signal meter IKSU-260 ELEMER, which is connected to a PC via an available COM or USB port (you must use a USB adapter).

In the process of maintenance at the application site for checking and tuning, the KTPS-PN functional unit must be removed from the cabinet and installed in the contact node of the SPAB-M stand in compliance with the requirements for connecting the corresponding adapter.

The disadvantages of the SPAB-M stand include:

- The need to remove the functional block KTPS-PN from the cabinet;

- Lack of inspection of internal connections;

- Significant labor costs for the maintenance of equipment KTPS-PN;

- Increased wear of the contact connections of the KTPS-PN cabinet.

A software and hardware complex for automated functional control of electrical installation structures is known, comprising a workstation, a connector block, a switching unit with corresponding channels and a connecting board, a transition block and a measuring unit, while a computer is used as a workstation and an external power supply unit with a circuit breaker is introduced and insulation breakdown monitoring device and internal power supply, in addition, the switching unit is equipped with a microprocessor controller with a control system a programmable current and voltage source, and the measuring unit with a voltmeter, while the first input-output of the workstation is connected to the input-output of the microprocessor controller of the switching unit, the second input-output of the workstation is connected to the digital input of the voltmeter of the measuring unit through the transition block, analog the voltmeter inputs are connected to the measuring outputs of the board of the connecting switching unit, the calibration output of this board is connected to the connector block, and its inputs to the outputs of the internal power supply I, in addition, the first output of the external power supply is connected to the input of the internal power supply, and its second output is connected to the power input of the voltmeter, (see, for example, patent for utility model RU 129281 U1, 06/20/2013, G06F 17/00) .

A device for checking and tuning is known for collecting data on the state of technological equipment of power plants, characterized in that it consists of three subracks, one of which is used to install service units: power supplies, voltage control unit, network devices, the second and third are used for installation functional blocks providing the collection of analog signals - unified signals of direct current and voltage, signals from thermocouples and resistance thermocouples, as well as the collection and delivery of a disk signals, moreover, the functional blocks have a redundant internal structure for converting the input signal and are connected by a local highway according to the RS-485 standard, which provides the possibility of sequential polling of functional blocks with a cycle of less than 20 ms, while filters are integrated into the functional blocks to suppress sinusoidal interference at frequencies 50 and 60 Hz, while in analog blocks galvanic isolation in digital circuits and high-precision measuring ADCs are used, and cabinet communication lines m functional blocks inputs to fully duplicated concentrators (.See.

Utility Model Disclosure

The technical result is to increase the reliability of automated verification of software and hardware systems of automatic process control systems inside cabinet connections between the terminals of the functional blocks and the cabinet terminals for connecting external sources and signal consumers.

The claimed technical result is achieved as follows.

The device for checking and adjusting the cabinet of the basic software and hardware complex of automated control systems is made in a single housing and contains in its design contacts for connecting to power circuits, a personal computer, a calibrator meter and input terminals of the cabinet.

Utility Model Implementation

The verification and tuning device (UPN) is intended for the maintenance of functional units operated in the cabinet of the safety control system of automatic control system KTPS-PN. UPN performs the functions of setting up functional blocks, their verification and / or technical examination, as well as checking the integrity of the electrical circuits from the tested unit to the corresponding terminal block of external connections.

Calibration of analog functional blocks is provided by the standard IKSU-260, a calibrated measuring instrument of unified signals included in the UPN.

UPN provides:

- health check of the BSD 16, BSD 32, BVD 16, BVD 32 blocks;

- performance test and configuration of BSA T, BVA T, BSA N, BVA N, BSA TS, BSA TP;

- verification of BSA T, BVA T, BSA N, BVA N, BSA TS, BSA TP blocks;

- checking the integrity of the electrical circuit from the terminal block of the external cabinet connections to the functional unit;

- Generation of reports on checking and setting up blocks for subsequent printing on a printer.

Device management, viewing and issuing generated reports is carried out using the specialized software “PROGRAMUPN” ПУЖЖ 0.000.178 installed on a portable laptop or personal computer connected to the UPN via the USB interface.

Additionally, UPN has the following features that are not available in the analogue.

The device allows connecting and disconnecting to the ХТ fields of the cabinet ШБ САУ КТПС-ПН without removing power from the cabinet.

UPN provides power to the included IKSU-260 calibrator-meter with a voltage of 12 V, 1 A.

A device for connecting to functional blocks does not require additional adapters and a contact node.

The power of the tested functional blocks is provided from the cabinet SB SAU KTPS-PN.

The device provides a check of the integrity of the electrical circuits from the tested functional unit to the corresponding output terminals of the cabinet ШБ САУ КТПС-ПН.

Thus, the technical result is achieved by a combination of essential features of a utility model.
