A circuit to perform the control logic function was designed, andtest had been carried out on some of its functions. During this, the means to anti-interference wasintroduced. Especially, a mechanism was designed to against the case of power off, it can be operatedby user with their hands, and can be switched easily between normal and abnormal state. Also it can beperformed as the user required stopping the door in any position.It is the key to turn over and lift garage door properly that ensuring the lift linkage. Traditionaldesign method is laborious and time consuming, it is hard to repeat and modify the parameters.There 如果帮助到您，请记得采纳为满意答案哈，谢谢！祝您生活愉快！ vae.la
