The invention belongs to the field of elevators, and discloses an anti-interference test method for elevator speed, which specifically comprises the following steps of: 1, receiving a transmitting mark transmitted by a transmitting end, and starting a timer; the emission mark is generated after the emission end emits a pulse light signal; step 2, judging whether a receiving mark sent by a receiving end is received in a timing period of the timer, if so, performing step 3, and if not, judging that the transmitting end is shielded; the receiving mark is generated after a receiving end receives a pulse light signal; 3, judging whether the receiving mark is sent by a receiving end corresponding to the transmitting end in the step 1 or not, and if yes, judging that the pulse optical signal transmitted by the transmitting end is received by the corresponding receiving end; and if not, judging that the receiving mark is an invalid mark, and affirming that the transmitting end is shielded. According to the method, the pulse optical signals are adopted, the two transmitting ends alternately transmit, meanwhile, the timer is combined with signal judgment of the transmitting ends and the receiving ends, time accurate judgment is achieved, and the detection precision is improved. Meanwhile, the invention further discloses an elevator system adopting the method.

    本发明属于电梯领域,公开了一种电梯速度的抗干扰测试方法,所述方法具体为:步骤1:接收发射端发射的发射标记、启动计时器;所述发射标记由发射端发射了脉冲光信号后产生;步骤2:判断在计时器的计时周期内是否接收到接收端发送的接收标记,若是,则进行步骤3,若否,则判断发射端被遮挡;所述接收标记由接收端接收到脉冲光信号后产生;步骤3:判断接收标记是否为与步骤1的发射端对应的接收端所发送,若是,则判断发射端所发射的脉冲光信号被对应的接收端收到;若否,则判断该接收标记为无效标记,认定发射端被遮挡。该方法采用脉冲光信号,两个发射端交替发射,同时采用计时器结合发射端和接收端的信号判断,时间精准的判断,提高检测精度。同时,本发明还公开了采用该方法的电梯系统。
