What does mechanical control of washing machine mean?
This is a button, like a fan, it is broken and twisted. There is also an automatic washing machine with LCD and other things, which can be touched with a touch, just like a mobile phone.
PLC control of automatic washing machine
According to my collection, let's take a look at this. Graduation thesis design, recommend a website with a very fine column: /html/ SF/lw/2009/0928/146347.html Opening report: /html/lunwenzhidao/kaitibaogao internship thesis:/html/Xi Shi writing guide:
PLC control of automatic washing machine
PLC programming PLC controls the automatic operation of the 4th floor _ Specific analysis and control requirements: (1) At the beginning, the elevator will be in any one (2) When an outgoing elevator signal arrives, the car will respond to the call signal, and when it reaches this floor, the car will stop running (the car door will open and automatically close after a delay of 3 seconds) (3) When an incoming elevator signal arrives, the car will ring the call signal. (The car door is opened, and it will automatically close after a delay of 3 seconds) (4) During the operation of the elevator car, that is, on the way up (or down) of the car, any outgoing call signal that descends (or rises) in the opposite direction will not respond, but if there are no other incoming and outgoing call elevator signals in front of the outgoing call elevator signal in the opposite direction, the elevator will respond to the outgoing call elevator signal. For example, the elevator car is on the first floor and will run to the third floor. In the second process, it can respond to the exhalation signal of the second layer, but it does not respond to the exhalation signal of the second layer. When arriving at the third floor, if there is no call signal on the fourth floor, the elevator can respond to the call signal on the third floor. Otherwise, the elevator will continue to run to the fourth floor, and then the national operation will respond to the elevator call signal from the third floor. (5) The elevator has the function of calling the elevator in the farthest direction. For example, if the elevator car is on the first floor and there are two floors, three floors and four floors at the same time, then the elevator car will go to the fourth floor to respond to the four floors. (6) When the elevator is not leveled or running, neither the door opening button nor the door closing button works. After the elevator car stops running, press the open button to open the car and press the close button to close the car. Please refer to the discussion forum for the reference procedure, and welcome everyone to participate in the discussion [discussion forum 1] [discussion forum 2]. Process control requirements for PLC control boilers: 1. Start: ignite at a certain time interval. The sequence of ignition is: fuel preheating-interval 1 min-air supply, sub-fire burning, mother fire burning-interval of 5 seconds-sub-fire and mother fire are turned off at the same time. 2. Stop: When stopping the combustion, it is required that the fuel preheating is turned off, the oil injection is turned off, and the air supply (blowing off waste gas and impurities)-the air supply interval is stopped for 20 seconds (furnace cleaning is stopped). 3. Automatic shutdown of abnormal conditions: During fuel combustion, when abnormal conditions (i.e. steam pressure exceeds allowable value or water level exceeds upper limit, or water level disappears), it can be automatically re-ignited according to the ignition procedure. Namely: abnormal situation-fuel preheating is turned off, fuel injection is turned off, air is supplied-interval is 20 seconds-furnace cleaning stops-abnormal situation disappears-lights are turned off. 4. Boiler water level control: After the boiler is started, when the water level is lower than the lower limit, the water inlet valve is opened and the drain valve is closed. When the water level is higher than the upper limit, the drain valve is opened and the inlet valve is closed. According to the process control, Mitsubishi FX series PLC is used to compile the control sequence flow: 1, start (X00 1) and output 1: fuel injection Y005, fuel preheating (Y00 1), time relay (t 1, the following is also 0./kl. Parameter 600)T 1 output 2: air supply (Y002), ignition separation Y003, separation stop (X002): output internal relay M 1 output 4: (m65438 output 4 simultaneously: interval T3 (parameter 200): (T3 normally closed) Y0023, abnormal situation. High water level input: X004 (high water level sensor) High water level input: X005 (low water level sensor) X3, X4, X5 outputs 5: M2 m2 control output 6: (m2 normally closed) Y00 1, (m2 normally closed m2 controls normal output. 4. Valve opening: bottom water level output X005: water level of inlet valve Y006 is high X004 output: valve opening restrictions of drain valves Y007Y006 and Y007 are interlocked, so the above control sequence tables (M2 normally closed) Y006 and (M2 normally closed) Y007 can basically be compiled into ladder diagrams, for example, the compiled programs are incomplete. [Reference Program and Ladder Diagram] Welcome to discuss PLC programming examples. The uncoiler is used to open the coil, the multi-star roller is used to flatten the steel plate, and the punching and shearing machine is used to punch and shear the strip into a certain length of steel plate. The buffer pit is used to buffer the punching shear feed and the uncoiling feed. The system drives AC motor as the driving force of feeding through frequency conversion governor. Analyzing the process of cutting each steel plate, the motor has to go through several steps: starting feed, running at a constant speed, slowing down and braking. Manipulator control manipulator can be divided into two working modes: automatic and manual ... Three-phase stepping motor control requirements: (1) can control the speed of three-phase stepping motor. (2) The forward and reverse rotation control of the three-phase stepping motor can be realized. .
Excuse me, how to control the washing machine to start?
Turn on the power and start it. You won't just eat and drink. A good dog will rush to New Oriental and roll. Gaga, Gaga, Gaga, Gaga, baby. Hahahaha, it's very program. No, no, no, ha, ha, ha, no, bang, bang, Samuel Hui, you. . . .
