摘要
当前高层建筑作为城市建设的主要标志之一。为了方便人们在高层进行出行和工作，很多的高层建筑在进行设计的时候都引进越来越多智能话和自动化的设计。电梯作为高层建筑设计必备的设设备，对电梯的功能进行加强和完善作为当前高层建筑的主要任务之一。
此次设计一款六层电梯，该设计通过软件和硬件配合进行设计，该设计可以实现对当前电梯内的人员进行体重监测，监测到体重大于设置的最大值进行声光报警提醒，防止电梯内的重量大于设置的最大值，在运行时出现故障，也防止电梯在人体重量较大的情况下损坏，通过数码管实时显示当前电梯所在楼层，当电梯到达对应的楼层时，当前楼层对应的指示灯点亮进行提醒，并实时显示当前电梯的运行状态为上行还是下行。为了防止电梯出现故障时有人被困电梯，此次设计额外添加对讲机的功能，用户可以在电梯出现故障时通过对将机了解是否存在被困人员。此次设计可以解决当前电梯发生事故时，不能及时发现被困人员的问题及其满足当前人们使用电梯的功能。

ABSTRACT
At present, high-rise building is one of the main symbols of urban construction. In order to facilitate people to travel and work in the high-rise, many high-rise buildings in the design of the introduction of more and more intelligent and automated design. Elevator as a high-rise building design necessary equipment to strengthen and improve the function of the elevator as one of the main tasks of high-rise buildings.
This design is a six-storey elevator, the design is designed through the coordination of software and hardware, the design can realize the weight monitoring of the current elevator personnel, monitoring the weight is greater than the maximum value of the set sound and light alarm to remind, to prevent the weight of the elevator is greater than the maximum value of the set fault, but also to prevent the elevator in the case of large human weight damage. Real-time display of the current elevator floor through the digital tube. When the elevator reaches the corresponding floor, the corresponding indicator light of the current floor is lit to remind, and real-time display of the current elevator running status is up or down. In order to prevent people from being trapped in the elevator when it fails, the design adds the function of intercom, so that users can know whether there are trapped people through the machine when the elevator fails. This design can solve the problem of not being able to find trapped people in time when an accident occurs in the elevator and meet the needs of people using the elevator.
Key words: six-floor elevator; Overweight monitoring; An intercom; Digital tube
