The invention discloses an elevator anti-electromagnetic interference method and device. The method comprises the steps that the count value variation of a timer T0 in a single-chip microcomputer within a set time is compared with a theoretical reference value, and if the count value variation is not equal to the theoretical reference value, it is determined that the timer T0 is disordered, and the timer T0 is corrected; and the count value variation of a timer T1 in the single chip microcomputer within a set time is compared with a theoretical reference value, and if the count value variationis not equal to the theoretical reference value, it is considered that the timer T1 is disordered, and the timer T1 is corrected. The device for realizing the method comprises the single chip microcomputer, and the single chip microcomputer is connected with a timer T2 and a timer T3, and shielding covers are arranged at the peripheries of the timer T2 and the timer T3. According to the method and the device, the problems that in an elevator control system with a single-chip microcomputer as the core, a timer TO or a timer T1 in the single-chip microcomputer cannot normally count due to electromagnetic interference during elevator operation are solved, and the situation that an elevator cannot normally operate due to the above problems is avoided.

    本发明公开了一种电梯电磁抗干扰方法及装置,所述的方法是:将单片机内部定时器T0在设定时间内的计数值变化量与理论参照值作比较,若不相等,则认为定时器T0出现了紊乱,纠正定时器T0;将单片机内部定时器T1在设定时间内的计数值变化量与理论参照值作比较,若不相等,则认为定时器T1出现了紊乱,纠正定时器T1。实现上述方法的装置,包括单片机,单片机分别连接有定时器T2和定时器T3。所述的定时器T2和定时器T3,它们的外围均设有屏蔽罩。本发明解决了以单片机为核心的电梯控制系统中,单片机内部计时器TO或计时器T1在电梯运行时因受到电磁干扰,无法正常计数的问题,避免了电梯因上述问题而无法正常运行的情况发生。
