The system allows control and total supervision of the protected area

Pilz Industrieelektronik presented on March 30 at a press conference its latest development in industrial safety, the SafetyEYE, a system consisting of three cameras that encompass of three-dimensional shape, all the space you want to control and protect in a working environment. The system, jointly developed with DaimlerChrysler for a plant of the multinational, will have plenty of industrial applications, "customers will be those who are new processes which implement the device", in the words of João Marques, Director Gerente of Pilz in Spain and Portugalthat presented the newly developed together with Armin Glaser, Product Manager of secure business automation systems.

The first safe camera system SafetyEYE opens new perspectives for automation, either industrial as non-industrial. In areas that are needed today still many sensors, SafetyEYE will create a Bell designed three-dimensional protection as you wrap the danger zone. The device also offers a high degree of flexibility and productivity in the field "safety" and a monitoring of objects and access protection without gaps in the field "security".

Pilz and DaimlerChrysler opened the doors to the third dimension of security in the middle of November of last year when presented in first joint development, which currently only works on a floor of the car manufacturer and is pending

The system consists of two units: the sensory unit, which provides data from images of the space monitored through three superdinámicas cameras, and the evaluation unit, which receives data from the images from the cameras through fiber optic cables and computes a three-dimensional image from a certain highly complex algorithms. Thus, it is possible to detect objects in space and determine its exact position. The information is superimposed on protection spaces configured on the system to check, e.g.. If the space is violated.

The evaluation unit is also composed of PSS, serving interface with the machine through its inputs and outputs and control that controls the full functioning of SafetyEYE.

The connection to the periphery can be done also through the system of safe bus SafetyBUS p and, later, through Ethernet SafetyNET p.

For its part, the PC's configuration and a special software package allows to configure protection and warning areas and all the parameters necessary for the functioning of the safe camera system. Three-dimensional warning and protection spaces overlap in the form of cubes and parallelepipeds semi-transparent color to images from the cameras.

When several spatial distributions, are required for different modes of operation of a machine, the distributions can switched dynamically during the work cycle of the machine through the system of safe bus SafetyBUS p or the digital inputs of the PSS control.

The operators do not lose flexibility because the defined protection spaces can adapt with a click of a mouse in the SafetyEYE Configurator. The monitoring of protection spaces already not aims, therefore, on technical needs but on the requirements of the sequences of processes of the operators, which can be configured with total flexibility.

Currently, the technique of security solutions are limited, as it can be seen in a robotic work station consists of one or more robots and fitted with a fence of protection.

With this system could replace the barriers and surveillance sensors

To identify the access and retention of persons in the danger zone, robots should generally be supplementary protection devices, such as solar fences of security and zonal laser, along with career end scanners in robots.

However, Optoelectronic Protective devices do not allow to monitor small spaces but, in any case, levels or planes.

On the other hand, when the visual field is not clear, the terminal must be protected also by means of safety mats. In these circumstances, full monitoring of the radius of action of a robot is not feasible or achievable only with great technical effort.

In addition, the current protection devices to trigger an immediate stop of the robot if there is a dangerous situation.

Every start-up costs time.

With SafetyEYE is different: an interruption of the area of protection does not automatically cause an emergency stop. When it violates the protection space, warning functions can be activated also to enable the robot to move with a very reduced velocity and the emergency stop is triggered only if the operator enters the danger zone.
