摘要：为提高升降机的平层精度，以单片机AT89C52为控制系统的核心，通过位置检测装置来采集吊笼运行的脉冲信号，将该计数值与标定模块的值进行了比较，利用新型接口芯片BC7281A实现了楼层的输入和显示，并采用ISD1420语音芯片进行语音提示，利用C51进行软件编程。在软硬件方面，采取了各种抗干扰措施，提高了系统的可靠性。现场运行结果表明，该平层控制系统运行良好，平层精度较高。

Abstract: Aiming at improving position precision of elevator, AT89C52 was used as the CPU of positioncontroller, the number of scaling program with the number from the calculation for the pulse in position detection device were compared. The new style interface chip BC7281A was used to realize input and display of the layer number, and the ISD1420 voice chip was used to realize attention voice. The software of control system was made with C51. The several antiinterference methods in the hardware and software were designed, and the reliability of the system was improved. The debug results indicate that the positioncontroller works very well, and it has high position precision.
Key words: elevator；positioncontroller; position detection device; antiinterference
