System and method for reminding passengers entering elevator cars of calling

The invention relates to the technical field of elevator engineering and discloses a system for reminding passengers entering elevator cars of calling. The system comprises an in-car calling button, a central processing unit (CPU), an elevator controller, a voice data storage unit and a voice generator. The calling button is arranged on a calling board of the elevator car and connected with the elevator controller. The voice data storage unit is connected with the CPU. The voice generator is connected with the CPU through an input/output (IO) interface. The CPU is in communication connection with the elevator controller through a communication unit. When the elevator controller detects that passengers enter the elevator and do not call timely after an elevator door is closed, the CPU reads corresponding voice information from the voice data storage unit and transmits the information to the voice generator to remind the passengers of calling timely. The invention further discloses a method using the system for telling the passengers to call the elevator to operate timely.
