SENSORS APPLICATION IN THE
INTELLIGENT ASSEMBLY AND
MANUFACTURING SYSTEMS

Nina DANIŠOVÁ
Karol VELÍŠEK

Abstract: The objective is generally to present application
of sensors at the intelligent manufacturing and
assembly systems. In this contribution is to present
specific design of monitoring systems at the intelligent
assembly and manufacturing systems, which is situated at
theInstitute Production Systems and Applied Mechanics.
The monitoring system is designed for two subsystems of
intelligent system. At the designed monitoring system are
used into mechanic, inductance, optical, pressure, and
camera sensors.

Key words:
system, assembly, manufacturing, sensors, monitoring

1. INTRODUCTION
Complexity of intelligent assembly and production
systems is characterizedmostly by their structure, element
connection and system environment. For function of
intelligent production and assembly systems is necessary
to receive a number of visual, acoustic and tactile
information.
In the intelligent assembly and production is necessary to
identify and prepare the information mostly about
function of basic technical devices (robots, assembly,
productionassistant devices), about controlling and
blocking functions. Realization of these functions
checking is provided by sensorial systems. At the
technical praxis are termed sensorial systems as
“monitoring systems”.

2. FUNCTIONS OF MONITORING SYSTEMS
APPLIED TO INTELLIGENT ASSEMBLY
AND MANUFACTURING SYSTEMS
One of the application areas of monitoring systems is the
area of intelligent assembly andmanufacturing.
Equipping of assembly and production systems by sensors
is one of the basic levels of increasing of automation and
machine intelligence. Sensorial systems provide scanning
and monitoring of various functions of assembly and
production process, assembly technology, properties of
assembly objects, mounted parts and properties of
environment.
Realization of monitoringfunctions provide suitable
sensor sorts, whereupon the supervisory systems provides
the control interventions. Sensors are the basic devices for
capturing of information and their transformation. On the
present monitoring systems have reserved structures,
which are realized according to application or purpose.
On the figure 1 is intelligent robotic agent.

Basic functions ofsensors applied to monitoring systems
are specified in the following groups:
1. Monitoring of handling devices status:
Deals mostly about monitoring of assembly robot status.
Monitoring of information of robot arm motions,
velocities, accelerations, temperatures, pressures, status of
electronics etc.
2. Monitoring of external environment:
For monitoring are used from simple sensors ofobject
presence.
3. Monitoring of the status of assembly and production
machines, assembly units, supply units and other
active elements of assembly and production system:
There is necessary to identify status of program steps and
status, which can affect reliability and safety of units and
devices running. Deals about information: turn on and off
of working units, status of important surfacesetc.
4. Monitoring of interactions:
Deals about information file of operations, at which
participates minimum of two elements of function system
(e. g. removal of parts out of moving conveyor). Purpose
of interaction information scanning is in evaluating of
system connections, which are determining for proper
function.
Among the most important interaction information fall
the geometricreading (mutuality of position), temporal
reading (present and temporal shift) and non-regular
function reading (breakdowns) [1].

3. PROBLEMS IN APPLICATION OF
MONITORING SYSTEMS
Basic problems, which relate to application of monitoring
systems in assembly and production, is possible to divide
to following groups:
specification of necessary identification and
monitoring tasks,...
