The invention discloses an elevator car door closing control device which comprises a sampling circuit, a control circuit, a door driving device and at least two weighing devices. The weighing devicesare uniformly arranged below a bottom plate of an elevator car and used for detecting the weight in the elevator car and outputting a weight analog signal; the sampling circuit samples the weight analog signal and outputs a weight sampling digital signal to the control circuit; and the control circuit controls the door driving device to work according to the weight sampling digital signal and drives an elevator car door to close. According to the elevator car door closing control device, whether passengers finish entering and exiting from the car or not can be accurately judged, the time forclosing the elevator door each time can be automatically adjusted, the good elevator taking feeling of the passengers can be improved, the service life of door opening and closing buttons can be prolonged, and the running efficiency of an elevator is improved.
本发明公开了一种电梯轿厢关门控制装置,其包括采样电路、控制电路、门驱动装置及至少两个称量装置;称量装置均匀设置在电梯轿厢底板下,用于检测轿厢内的重量并输出重量模拟信号;采样电路对所述重量模拟信号采样,输出重量采样数字信号到控制电路;控制电路根据重量采样数字信号控制门驱动装置工作,驱动电梯轿厢门关闭。本发明的电梯轿厢关门控制装置,能准确判断乘客是否已结束进出轿厢,自动调整电梯每次关门的时间,既能增加乘客的乘梯好感度,又能延长开关门按钮的使用寿命,提升了电梯的运行效率。
