Problems solved by technology

[0002] When operating machines and industrial plants with operating and viewing devices, it may occur that operating steps in automation technology for safety-critical applications, e.g. Ejection of the punching plunger, which may cause damage and hazard to the body and life of the operator of the machine
Such injuries can be caused by the fact that the operator's limbs may be located in the danger zone of the machine during the operating process
Such injuries can also result from, for example, the operator of the machine being able to operate with one hand while simultaneously entering the danger zone of the machine with the second hand

Embodiment Construction

[0013] according to figure 1 , shows an operating and viewing device 1 having a display, for example an LCD display, and a touch-sensitive sensor, for example a resistive multi-touch sensor, arranged in front of it.

[0014] In this case, the graphic software for controlling the display and analyzing the touch of the touch-sensitive sensor is designed in such a way that the operating element is divided into a first operating area 11 and a second operating area 12 for enabling safety-critical applications, wherein in this second A first number L of five touch points L1, . . . Two quantity R. Wherein, the position data P1 of the first operation area 11 and the position data P2 of the second operation area 12 are selected in this way, that is, for example, touch all touch points L1, . . . , L5 of the first operation area simultaneously with multiple fingers of the left hand and all touch points R1, . . . Only when R1, ..., R5 are touched, the opening of the safety-critical app...

Abstract

A method of operating an operator control and monitoring device for safety-critical applications in which the control and monitoring device (1) includes a display and a touch-sensitive sensor, wherein a control element is shown on the display which an operator must touch to obtain an approval for a safety-critical application that is granted for as long as the control element is being touched, wherein first and second numbers of touch points are respectively displayed in first and second control zones (11, 12), position data of the first and second control zones is selected such that the fingers of a human hand cannot simultaneously touch all touch points of the first and second control zones, and wherein the approval for the safety-critical application is only granted if all touch points from the first and second control zones are being touched.

Description

technical field [0001] The invention relates to a method for operating an operating and viewing device for a safety-critical application, wherein the operating and viewing device comprises a display and a touch-sensitive sensor, wherein during preparation of the safety-critical application to be activated , an operating element is displayed on the display, which must be touched by the operator in order to switch on, wherein switching on is permitted for the same length of time as the operating element is touched. Background technique [0002] When operating machines and industrial plants with operating and viewing devices, it may occur that operating steps in automation technology for safety-critical applications, e.g. The ejection of the punching plunger may cause injury and danger to the body and life of the operator of the machine. Such injuries can be caused by the fact that the operator's limbs can be located in the danger zone of the machine during the operating proce...
