TH30358B - A complete machine for sweeping the elevator push button. - Google Patents

Abstract

Complete machine for sweeping The push-button switch for the elevator cabinet consists of a separate switch and a circuit of illumination. For each building floor serviced with elevator cabinets and control circuits that connect each circuit in a horizontal row / column matrix. To sweep the switch that has been driven And make the keypad shine Relative to the registered call Each separate circuit has a switch module that responds to the sweep signal from the control circuit by generating a signal driven by push-button switches. The triggers that are located there, are driven by the control circuit to generate a luminous signal. Given to a separate circuit for each call. Registered to trigger the LED and light the corresponding keypad. The control circuit generates a sweep signal, reads the excitation signal by a switch and produces an illumination signal. During separate scheduled cycles Each circuit's pulse-holding module responds to the luminous signal. To maintain the LED brightness for a longer period of time. Of scheduled cycles, switches and circuits of illumination And the control circuit operates together To generate and respond to signals that are driven by a switch With different sizes When taking advantage of the access control switch to close the selected floors
