The clock circuit as shown in Figure 3 ( right) shows: crystal oscillator is used in 12MHZ, XATL2 and XATL1 were 18 and 19 feet of scm. Fig. 3 overall plans 5 display circuit design This circuit uses a 8 digital tube display, from 74ls245 to drive 8 digital tube display elevator to arrive the number of floors and the operational status of the elevator, wherein the digital tube of 6 feet ( DP ) bright said elevator at this point in the uplink, if not bright said elevator in the downlink. microcontroller P2 port as the output port and the output activelow. The circuit shown in figure 4: Fig. 4 overall plans motor positive inversion of control In this design in order to facilitate the motor positive and negative use two light tube to represent, as shown in Figure 5 : the use of SCM P0 port output port to drive the luminous tube, as is the P0 to add resistance, in which L1 light indicates the motor forward, L2 lights, L3 light indicates that the motor reverse motor stop, while the elevator door. L3 out that the elevator door, elevator running L1 and L2 must have a bright, to express elevator uplink and downlink Fig. 5 overall plans 6 system software design Because the design of the keyboard matrix to replace the outgoing select button, which is the direction of the elevator call button and choose according to these keys to decide, so the chip to scan the keyboard constantly to get the call state. In order to control the operation of the lift. The keyboard matrix scanning is an important part of the software design of the system, in addition to the storage key information of each layer to keyboard scan, and then pare and elevator operation, to determine whether the response of each layer of the call ( elevator only in response to the same direction, finally call ) is floor display part, this design is through a delay circuit to display the location of the elevator. The software design includes the following sections: The initialization procedure so that the digital display 1 indicates that the elevator in a building, and the L3 light that elevator door etc. Others entered the elevator。 S9: five floor down the call button, the button is pressed five floor elevator ride down to single chip, and the signal into a fixed unit, wait to judge whether the response to this call the elevator to the floor。 外文翻譯 頻率合成器設(shè)計 系 別： 電子與電氣工程系 年級專業(yè)： 2021 級電子信息工程（專升本） 姓 名： 學(xué) 號： 125031108 題目名稱： 頻率合成器 設(shè)計 指導(dǎo)老師評語： 指導(dǎo)老師簽名： 年 月 日 1 外文翻譯 The elevator controller based on Singlechip microputer Abstract: the design is based on singlechip microputer to control the use of the appliance, the use of digital tube to display the position and direction of the floor, using two LEDs to replace the motor, to achieve the motor positive inversion by singlechip microputer to control the LED on and off, to check the position of the elevator through the timer delay.
