电梯控制系统由呼叫到响应形成一次工作循环，电梯工作过程可分为自检、正常运行、强制运行等三种工作状态，电梯在三种工作状态之间来回切换，构成了完整的电梯工作过程。 1．电梯的自检状态 PLC后上电，电梯运行进入自检状态，检测项目为：（1）供电电压正常。（2）各控制回路电源电压正常。（3）相序正确，相序继电器吸合，安全回路中各开关接触良好，急停继电器可靠吸合。（4）关门到位后，各厅门门锁和轿门门锁触点吸合正常，保证门锁继电器可靠吸合。（5）开、关门回路正常。（6）电梯制动器动作正常可靠。（7）井道中各开关位置正确，动作可靠。（8）上、下限位开关，上、下极限开关位置正确，动作可靠。（9）变频器处于正常工作状态，准备就绪信号输出有效。（10）PLC处于正常工作状态，其运行模式开关处于RUN状态。在以上条件都得到满足后，电梯才可以进入正常运行状态，否则，无法进行正常运行。 2．电梯的正常运行状态电梯完成一个呼叫响应的步骤如下：（1）电梯在检测到门厅或轿箱的召唤信号后将此楼层信号与轿箱所在楼层信号比较，通过选向模块进行运行选向。（2）电梯开始起动，通过变频器驱动电机拖动轿箱运动。轿箱运动速度由低速转变为中速再转变为高速，并以高速运行至目标层。（3）当电梯检测到目标层减速点后，电梯进入减速状态，由高速变为低速，并以低速运行至平层点停止。（4）平层后，经过一定延时开门，直至碰到开门到位行程开关；再经过一定延时后关门，直到安全触板开关动作。 3．电梯强制运行状态（1）检修运行当电梯的初始位置需要调整或电梯需要检修时，应设置一种状态使电梯处于该状态时不响应正常的呼叫，并能移动到导轨上、下行极限点间的任意位置。检修时，打开检修开关，PLC程序进入检修模式，电梯以检修速度运行。按住强迫上（下）行按钮，这时上（下）行继电器吸合，同时抱闸打开，变频器收到方向信号后，电梯启动并以检修速度运行。（2）消防运行消防返回状态：火灾时，设在大厅的消防开关合上后，消除内选和外呼信号，电梯向下返回消防层站，在返回消防层站的过程中，电梯不应答任何内选和外呼信号。消防员专用状态：到达消防层后，电梯进入消防员专用状态，每次只应答一个内选，且只有一直按住内选按钮，直到关好门后此内选信号才被登记。此状态下，外呼信号不登记。（3）泊梯泊梯开关闭合，进入泊梯状态。若电梯不在泊梯层，则消除内选和外呼信号，自动返回泊梯层，然后关门，断开电源继电器和变频器电源接触器，变频器断电，进入泊梯状态。五、控制系统软件设计 1．软件流程
2．模块化编程电梯控制系统是集选式控制方式，适合采用模块化编程方法，下面介绍几个模块的梯形图程序：（1）电梯自检模块：安全回路中各开关接触良好，安全回路信号（10001）输入，安全继电器（01169）闭合。当电梯开关门完成（01037），关门到位<PLC

The elevator working process can be divided into three working states: self inspection, normal operation and forced operation. The elevator switches back and forth between the three working states to form a complete elevator working process. 1. The self inspection status of the elevator is powered on after PLC, and the elevator runs into the self inspection status. The inspection items are: (1) The power supply voltage is normal. (2) The power supply voltage of each control circuit is normal. (3) The phase sequence is correct, the phase sequence relay is closed, the switches in the safety circuit are in good contact, and the emergency stop relay is closed reliably. (4) After the door is closed in place, the contacts of each hall door lock and car door lock are pulled in normally to ensure that the door lock relay is pulled in reliably. (5) The opening and closing circuits are normal. (6) The elevator brake operates normally and reliably. (7) Each switch in the hoistway is in correct position and operates reliably. (8) Upper and lower limit switches, upper and lower limit switches have correct positions and reliable actions. (9) The frequency converter is in normal working condition, and the ready signal output is valid. (10) PLC is in normal working state, and its operation mode switch is in RUN state. After the above conditions are met, the elevator can enter the normal operation state, otherwise, it cannot operate normally. 2. In the normal operation state of the elevator, the steps for the elevator to complete a call response are as follows:. (2) The elevator starts, and the motor driven by the frequency converter drives the car to move. The moving speed of the car is changed from low speed to medium speed and then to high speed, and it runs to the target floor at high speed. (3) When the elevator detects the deceleration point of the target floor, it enters the deceleration state, changes from high speed to low speed, and stops at the leveling point at low speed. (4) After leveling, open the door after a certain delay until reaching the travel switch of opening the door in place; After a certain delay, close the door until the safety touch switch acts. 3. Elevator forced operation state (1) Maintenance operation When the initial position of the elevator needs to be adjusted or the elevator needs to be repaired, a state should be set so that the elevator does not respond to normal calls when in this state, and can move to any position between the upper and lower limit points of the guide rail. During maintenance, turn on the maintenance switch, the PLC program enters the maintenance mode, and the elevator runs at the maintenance speed. Press and hold the forced up (down) button, then the up (down) relay is closed, and the holding brake is opened at the same time. After the frequency converter receives the direction signal, the elevator starts and runs at the maintenance speed. (2) Fire fighting return status of fire fighting operation: in case of fire, after the fire switch set in the hall is closed, the internal selection and external call signals are eliminated, and the elevator returns to the fire floor station downward. During the process of returning to the fire floor station, the elevator does not respond to any internal selection and external call signals. Special status for firefighters: after arriving at the fire floor, the elevator enters the special status for firefighters. Only one internal selection is answered each time, and the internal selection signal is registered only after the internal selection button is pressed and held until the door is closed. In this state, the outbound call signal is not registered. (3) The parking ladder switch is closed to enter the parking ladder state. If the elevator is not on the parking floor, eliminate the internal selection and external call signals, automatically return to the parking floor, then close the door, disconnect the power relay and the inverter power contactor, and the inverter is powered off to enter the parking state. 5、 Control system software design 1. Software flow
2. Modular programming The elevator control system is a centralized selection control mode, which is suitable for modular programming. The ladder program of several modules is introduced below: (1) Elevator self inspection module: all switches in the safety circuit are in good contact, the safety circuit signal (10001) is input, and the safety relay (01169) is closed. When the elevator door is opened and closed (01037), the door is closed in place<PLC
, man-machine control, process design requirements and program outline of high-speed drawing frame.
1 Preface
The key of cotton spinning process - drawing can adapt to the combined drafting of various processes such as pure cotton spinning, pure spinning and blending of cotton type chemical fiber and medium long fiber, so as to improve the evenness of long sliver segments and the straightness and parallelism of fibers, and make the mixing of fibers of different quality more uniform in the sliver. It can be used for one drawing after combing, which shortens the process and has good sliver quality, especially for reducing the weight unevenness and improving the CV value of sliver. Its quality index can reach the level of 25% of the relevant Uster statistical value.
The design speed of the new domestic high-speed drawing frame is 600-800 m/min or above, and the actual opening speed should reach 400 m/min. Most of the new domestic high-speed drawing frames are double eyes, and single eye drawing frames have been successfully developed.
2. Transmission system
2.1 Main
electric machinery
It can be a double speed motor, most of which are variable frequency motors. Its speed regulation is convenient and accurate, the startup is stable, the speed opening time is adjustable, and the power saving effect is obvious. Generally, the motor is equipped with electromagnetic braking, the braking process is stable and reliable, and the braking time is ≤ 0.3s.
2.2 The traction system is driven by synchronous toothed belt and the guide roller is driven by flat belt, which reduces the number of transmission stages, improves the transmission accuracy, flexibility and reliability, stabilizes the drafting effect, reduces the noise, eliminates the coarse and fine knots caused by turning on and off, and ensures the spinning quality.
