DEVICE FOR MONITORING WAITING PEOPLE STAYING STATE IN WAITING AREA

摘要

PURPOSE: To accelerate a signal processing and to reduce manufacturing cost by dividing a waiting area into plural meshes, detecting infrared ray radiant quantities generated by waiting people in the respective meshes and displaying corresponding number of waiting people integrated numbers. ;CONSTITUTION: An elevator waiting area 1 is divided into plural rectangular meshes 2-5 and infrared ray detectors 6-9 are hung on the lower ceiling surface of a waiting area center part so as to face each other with representative points P1-P4 capable of surely detecting the total quantity of the infrared radiant quantities emitted by the respective waiting people in the respective meshes 2-5. Then, the detected values of the infrared ray detectors 6-9 are subjected to sampling-and-holding at every prescribed time by interfaces 10-13, converted to digital quantity and inputted to a CPU 14. Then, the respective infrared ray radiant quantities are collated with the waiting people integrated numbers by using the discrimination condition table of a RAM 15 and when coincidence is detected, code data for indicating the number of integration are inputted to a display device 17 and the number of waiting people integrated number is displayed. This processing is repeated and the number of waiting people integrated number is displayed at every prescribed time interval.;COPYRIGHT: (C)1994,JPO&Japio
