The COMPACS® computer monitoring system for machinery health control and accidents prevention
The stationary equipment monitoring system COMPACS® serves for safe ecological resource-saving operation of fire explosive production facilities, accidents prevention, production failures and units health control by means of stationary computer monitoring. The COMPACS® system automatically provides vibration analysis extrapersonal diagnostics, monitoring and health forecast of the units, issuing recommendations for operators and chief executives on the nearest urgent actions to be taken by means of the diagnostic network.
Condition (Health) Monitoring – is diagnostics of the main equipment and its assemblies malfunctions with a probability close to 1, on continuously adjoining such time intervals when the machinery condition does not change significantly. The machinery condition monitoring allows to detect timely the destructive loads, defects and malfunctions and to take efficient actions on the restoration of the acceptable condition and to stop the malfunctions developing.
The COMPACS® system is an all-purpose comprehensive machinery condition monitoring system which possesses a flexible distributed parallel-serial architecture, providing a high speed and accuracy of the information processing (scanning rates for rotating equipment are less than 0,02 min per channel, for stationary equipment - on a real-time basis), which allows to carry out the following main principles:
- Information Completeness Principal provides a diagnostic criteria choice, which reduces the failure omission probability.
- Sufficiency Principal determines a choice of the minimal sensors number, which provides observability of the machinery health.
- Invariance and Collective Identification Principal regulates selection of collective diagnostic principles, invariant to the machine construction and connection with its health parameters.
- Structural Flexibility and Programmability Principal provides realization of an optimal parallel-serial system structure.
- Measuring Path Faultiness Correction Principal carried out through computational methods (correction of sensors nonlinear effect, gain-phase characteristics, match-converting links, etc.) allows to provide high metrological characteristics of diagnostic and monitoring systems with small equipment costs.
- Principal of Self-diagnostics and Automatic Check-up of the measuring and controlling system channels provides an easy launch, maintenance and repair of separate channels, metrological and functional system reliability, its survival rate and adjustability to the constant changing real production conditions.
- User-friendly Interface with Maximal Information Capacity of the Display Principal allows an operator to identify the technological system general health, at mere sight of the display and to get a designator instructions on the nearest urgent actions.
- Multilevel Structure Principal allows specialists with different qualification and responsibility levels to operate the system.
The COMPACS® comprehensive monitoring system uses such non-destructive control methods, as vibration, acoustic emission, thermal, electric, vortex-current, acoustic, optical and other. The complex usage of this methods allows to control both rotating (pumps, compressors, etc.) and static equipment (columns, reactors, tanks, pipelines) on the single soft-hardware platform and in the common information environment, which constitutes the COMPACS®-AE system.
Vibration sensors allow to measure 3 vibration parameters simultaneously: vibration acceleration, velocity and vibration displacement. Joint analysis of vibration acceleration, velocity, vibration displacement and their growth rates, stochastic and spectral-correlation characteristics of vibration parameters allows to detect the defects at the formation stage, which has been proved by the 25-years operating experience of the COMPACS® system, implemented at hundreds of factories of 12 industries.
The comprehensive stationary equipment monitoring system COMPACS® belongs to the first class systems (according to the RF GOST R 53564-2009) and can be used for the comprehensive processing station monitoring, including objects of the first, second and third categories with the dangerous units automatic blockage function, and provides the safe resource-saving machinery operation according to the actual health.
Usage of the COMPACS® monitoring system allows an enterprise to pass to the resource-saving machinery operation according to the actual condition, which is allowed by the appropriate national standards of the Russian Federation: GOST R 53565-2009 "Condition Monitoring of Dangerous Industrial Objects Equipment. Vibration of centrifugal pump and compressor units", GOST R 53564-2009 "Condition Monitoring of Dangerous Plants Equipment. Monitoring systems requirements", GOST R 53563-2009 "Condition Monitoring of Dangerous Industrial Objects Equipment. Regulations", other normative-technical documents of the Russian Federation. The COMPACS® system allows to avoid groundless repairs and substantially enlarge the machinery operational periods.

SCADA - The СORNET® Distributed Fieldbus
Appeared in 1991, the CORNET® has become the first Russian distributed fieldbus of measuring and control modules that provides data collection from various sensors (vibration, temperature, pressure, flow rate, current, acoustic emission, discrete signals, etc.) and control signal output. Being produced in 1996 in the USA, the fieldbus consists of 2 cables (coaxial or twisted pair). Data transmission is carried out in Manchester-2 format.
Sensors construction provides efficiency and metrological characteristics of the Vibration Analysis System COMPACS® in the conditions of the real-time machinery operation in the continuous health monitoring mode. The COMPACS® system sensors mounting does not presuppose violation of the machinery safe functioning; all sensors are mounted without violation of the unit design, thus, coordination with a manufacturer is not required.
The CORNET® fieldbus includes 2 basic peripheral modules:
- universal programmable PIM™ module, that has 8 analogue inputs and a feature for programming the type of connected sensor and the parameters of measuring channel;
- discrete I/O module 4428, that has 16 programmable channels of discrete block I/O with galvanic decoupling.

The COMPACS® system modules
The COMPACS® system remote modules are mounted in a close proximity to the measuring object, where measuring sensors are placed. The modules are placed in protective ducts or metal boxes. There are special explosion-proof modules of 0ExiaIICT5 class, and sensors of 0ExiaIICT6 class, which can be used in all fire explosive class areas, they also possess dust and water protection IP-54. Working temperature range of the modules varies from –40 to +60 °С. One of the main distinctive features of the COMPACS® systems is a low power consumption (does not exceed 50 mWt per channel) of remote modules distributed fieldbus at a broad transmission band (0…25) кHz of the measuring channels.
The modules can be connected to the diagnostic station through two connection lines, one of which is the power supply and control line, and the other is the signal line. The length of communication lines is more than 500 meters. The power and control line (PCL) is used for transmission of control signals and powering the module. The signal line (SL) is used for transmission of analogue and digital signals to the diagnostic station.
The wireless fieldbus Compacs-Radio-Net®, based on Ethernet-intellectual modules 4440, can be built.
Automatic Expert System
The main advantage of the Vibration Analysis System COMPACS® is the automatic expert system for decision-making support.
The COMPACS® Expert System (ES) is designed for automatic diagnostics and predicting the equipment health. The COMPACS® ES uses vibro-acoustic, acoustic emission, current, ultrasonic, thermal and parametric (pressure, level, flow rate, temperature) diagnostic methods. The COMPACS® ES belongs to the class of decision-making support expert systems, which means that the ES aims at helping the operators to take the necessary grounded decisions regarding the machinery operation and maintenance.
The COMPACS® ES inferencing Principal
The automatic expert system for decision-making support uses such current values of diagnostic features as input data, their time trends, spectral and cepstral signal characteristics. The expert system is invariant to the diagnosed equipment parameters, which makes the diagnostics possible even without full data on the machinery design features. Automatically, without specialists (diagnosticians) assistance, the expert system detects defects and malfunctions and issues the task list that should be followed in order to make the machinery operational.
Receiving signals from the sensors located on the diagnosed equipment the COMPACS® system generates a vector of diagnostic indicators consisting of 3 groups:
- general type parameters by signals from sensors;
- rate of parameters change;
- indicators calculated as a result of processing trends, spectra and cepstra.
The diagnostic indicators vector then enters a processing unit of the Expert System logic predicates. The conclusion made by the expert system is based on the results received from the latter.
As a result, the automatic diagnostic expert system generates diagnostic instructions, displayed on the main screen in the form of text messages, and also generates commands to the voice warnings output module. The expert system allows to diagnose rolling bearings, valves, reducers, electric motors, centrifugal pumps, centrifugal and piston compressors. The system can evaluate the rate of a parameter change by any parameter, and this is one of the diagnostic indicators which is invariant to the machinery type.
Independence from the diagnosed machinery allows users to configure and distribute the system easily. Due to availability of the built-in programming language – CDPL, it is easy to implement new rules based on the personnel experience of the system operation.

The COMPACS® system economic benefits
Adoption of the safe money-saving operation management technology, based on the COMPACS® monitoring systems, has several goals:
- elimination of accidents and downtime due to the machinery failures;
- maximal increase of the technological complex and its machinery run-to-failure;
- decrease of duration and complexity of processing units shutdown repairs;
- operational expenditures and losses by means of inefficient unplanned and scheduled-preventive repairs elimination.
Emergencies or sudden failures of the machinery can happen when the actual operation time between the unit failures exceeds the regulatory schedule-based preventive repair period. In order the malfunctions development become observable, it is obligatory to carry out continuous diagnostics with an automatic objective results delivery to the departments heads and specialists, responsible for the machinery operation. Machinery real-time health monitoring allows to transfer the biggest part of failures from the sudden failure category to the gradual and preventable ones.
Economy due to reduction of repair expenses is possible by dint of the regulatory schedule-based preventive repair and off-schedule repair elimination because of the machinery operation according to its actual health. Due to timely maintenance, intentional repairs, liquidating fundamental causes of the machinery failures (technology LiFCF™), the equipment operation and repair expenses reduce in 6-8 times.
Economy due to reduction of raw stock and the equipment losses from accidents can be calculated due to the lower probability of the accidents occurrence, given by the COMPACS® systems. Conditional time periods between accidents before and after the machinery is commissioned to the operation according to its actual health, can be calculated by the total probability of the unit failure omission by all reasons, which counts less than 2% for the COMPACS® systems.
Economy due reduction of the unit downtime losses caused by the machinery failures, can be defined as extra charge losses reduction, not obtained in the time unit due to the technological complex downtime.
Economy due to the regulatory schedule-based preventive repair period reduction and acceleration of commissioning is connected with timely and purposeful maintenance, repair and elimination of the fundamental reasons of poor efficiency and equipment downtime.
Today economy effect from the COMPACS® systems implementation in Russia and abroad is more them 100 billion rubles.
