DEVICE AND METHOD FOR DOOR AREA MONITORING
The invention relates to a device for monitoring the door area of an at least partially glazed door. The device comprises a transmitter, an image recorder, a control unit, and an evaluation unit. The transmitter is used to emit at least one transmission pulse of electromagnetic radiation. The image recorder comprises a receiver matrix having at least one first receiver block, which has a plurality of first receivers. The first receivers of the first receiver block are designed and arranged in such a way that they receive reflected signal components of the transmission pulse in a second predetermined distance range of an outer region of the door area, the distance range being determined in relation to the door. Each first receiver has a memory unit which is designed to integrate and store the reflected signal components received. The control unit is configured to trigger a transmission pulse of the transmitter and to activate the first receivers of the first receiver block for a predetermined first receiving period after a predetermined first idle period which is longer than a period in which a signal of the transmission pulse reflected by the glazed door reaches the first receivers of the first receiver block. The evaluation unit is configured to read the stored signal components of the respective receiver and to process them into topography image data and to compare the topography image data with stored reference image data for a free door area, or is configured to read the stored signal components of the respective receiver and to determine a distance value on that basis and to compare the respective distance value with a stored reference value for a free door area.
