In recent years, single-chip micro-computer with its strong vitality of rapid development in industrial control, smart instrumentation, intelligent equipment and household appliances, and other fields has been widely used and therefore aroused great concern to all walks of life, with wide Development prospects. Papers design is a microprocessor controlled multi-function signal generator. The design objective is to enable students through this practice, enhance the expansion of SCM and its practical application interface design capacity. The system software can run on DOS and Windows family of operating systems platform. Complete the design of the main functions: microprocessor voltage required for smooth access, 8 K bytes curing process storage capacity, Qiduan digital display, 3 × 4 of 12 matrix keyboard, waveform generator and voltage transformation functions, with eight Accuracy of D / A converter functions, and reset the clock circuit circuit and the completion of related software design. SCM 8031 to the present system as the core, configure the appropriate external interface circuit, with assembly language development, consisting of a microprocessor controlled multi-function signal generator. Hardware circuit design includes three parts: First, the power of the design of the system is expanded, that is the function of internal microcontroller units (such as ROM, I / O, timing / counter, interrupt system, etc.) capacity can not meet the application requirements The need for expansion outside the film, select the appropriate chips, the design of appropriate circuit; Third, the system configuration, that is, in accordance with the functional requirements of targeted peripherals such as keyboards, D / A converter, and so on. System of software is based on the function of the system requirements and design, to achieve a reliable system of functional requirements.

求购
所谓幸福 一拖二空调器是利用一个室外机来带动两个室内机运转的一种机型。 一拖二空调器使用的条件： 必需是相邻的两个房间，因为两个室内机共用同一个室外机，安装连接管时两个室内机的连接管同时接入同一个室外机，如果两个房间不是相邻，而是离的较远，这样就需要较长的连接管来同室外机连接，因此容易造成制冷效果不好，加大了安装难度，并且不经济。 房间面积不是很大。虽然目前各大品牌都有自己的一拖二产品，但产品范围有限，一般制冷量在2000W~3200W之间，如果房间面积在空调的制冷范围以外，就达不到预期的制冷效果。 房间大小相差不是很大。一拖二空调一般采用两个相同制冷量的系统或制冷量相差不是很大的系统，这就要求房间面积相同或相差在几个平方米以内。 一拖二空调器选购时应注意： 真一拖二空调器结构上有两个独立电源、两个压缩机，它的两个室内机和压缩机可以单独运行，互不干扰。制冷效果好，冷量分配均匀，但价位较高。 假一拖二空调器结构是单一电源，单一压缩机，两个室内机不能单独启动和停止，冷量的分配是由冷量分配器将冷量分配到两个室内机，制冷过程中容易产生冷量分配不均匀现象，使用、维修不方便，但价位相对较低。 所以消费者在购买过程中，一定要咨询清楚是何种类型的一拖二，以免上当受骗。
