The Taiji Diagram was known as the "First Diagram in China" and had a wide range of applications. It appeared in many famous buildings such as the Dacheng Hall of the Temple of Confucius and the Baiyun Temple. It also appeared on clothes such as Taoist robes and fortune-tellers 'stalls. In terms of the state of the universe, it was initially a chaotic state of "Wuji". Heaven and earth were not separated, Yin and Yang were unknown, and all things were mixed into one. Later, chaos gradually separated and became orderly. With the circumference of heaven and earth and Yin and Yang, this was "Tai Chi". Tai Chi gave birth to Two Elements, which could be understood by the changes of cold and heat in a year (or a day). The winter solstice was when extreme Yin gave birth to Yang, and the summer solstice was when extreme Yang gave birth to Yin, and the winter solstice was when extreme Yang gave birth to Yin. The "two elements" gave birth to the "four signs". The winter solstice to the summer solstice was yang. The winter solstice to the vernal equinox was relatively cold, which was yang in yin (Shaoyin). The vernal equinox to the summer solstice was relatively hot, which was yang in yang (Laoyang). The summer solstice to the winter solstice was yin. The summer solstice to the autumnal equinox was relatively hot, which was yin in yang (Shaoyang). The autumnal equinox to the winter solstice was relatively cold, which was yin in yin (Laoyin). The Four Symbols gave birth to the Eight Trigrams. Through further refinement, Yin and Yang were judged according to the cold and heat of different stages, and then the combination of Yin and Yang from inside to outside of each position of the Eight Trigrams was determined to obtain the hexagram symbol. For example, the Zhen position from inside to outside was Yang, Yin and Yin, and the symbol was Yu; the Li position was Yang, Yin and Yang, and the symbol was Yu; the Dui position was Yang, Yang, Yin and the symbol was Yu; the Qian position was Yang, Yang, and the symbol was Yu; the Xun position was Yin, Yang, and the symbol was Yu; the Kan position was Yin, Yang, and the symbol was Yu; the Kun position was Yin, Yin, and the symbol was Yu. The eight trigrams were divided into eight directions, and in the middle was the Taiji Diagram. This was the basic meaning and principle of the Taiji Eight Trigrams Diagram. Furthermore, the Eight Trigrams developed outward. The theoretical basis was that Yang was born from Yin, and Yin was born from Yang. For example, the fruit rotted from the inside, the explosion spread outwards from the center, and the sun shot out from the center to the surroundings. All of these phenomena were consistent with the hexagram that Tai Chi gave birth to the two elements, the two elements gave birth to the four images, and the four images gave birth to the Eight Trigrams.

There were many ways to tie a bow, and the following were some of the more common ones: 1. The bowknot at the waist: - He placed the short side under the long side. - The short one was wrapped around and the strap was tightened. - The long one came up from below the short one. - The long one was folded, and the folded one was passed through the circle formed by the short one. - After tidying up, he pulled the straps on both sides to the same length to complete the bow. 2. How to tie the bow on the collar: - First, he crossed the two straps, one above and one below. - The upper strap wound around the lower strap, then hung down from the middle of the two straps and tied a slipknot. - He folded the lower strap into an S-shape and placed it on the right side along the strap. - Then, he used the ribbon on it to wrap around the bow from the top to the bottom. - After the strap on the top went around the bow on the right, it folded into the other bow. - He slowly tidied up the bow after it was formed, tightened it, and fiddled with it a little. The beautiful and flat bow was completed. The above were the steps of the two common ways to tie a bow.

A spaceship was usually made up of a re-entry module, a service module (propulsion module), an orbital module, and emergency rescue equipment. The overall shape of the spacecraft in science fiction movies was streamlined and some had wings, but this was mostly based on the design of the aircraft on Earth that was in line with the flutter. In reality, the spacecraft operated in outer space, and flutter was not the main consideration. However, he didn't manage to find the exact diagram of the spaceship, so he couldn't provide any more information. The novel "Hundred Years of Spaceship" is equally exciting.

The following is a basic method to draw a positive and negative ladder diagram and circuit diagram: ** 1. Confirm control requirements and I/O allocation ** 1. ** Clear control requirements ** - Usually, the forward and reverse control required the motor to rotate forward, reverse, and stop through buttons, and it had to be interlocked with forward and reverse (to prevent short circuits caused by forward and reverse rotation at the same time). It might also require thermal relay for overload protection and other functions. 2. **I/O allocation confirmed ** - ** Inputs **: For example, the start button for forward rotation, the start button for reverse rotation, the stop button, and the overload protection signal of the thermal relay are all used as input signals. These input signals should be distributed to the corresponding input terminal of the PC. For example, in the case of the Mitsui PC, it may be X000, X001, etc., and in the case of the siemen PC, it may be I0.0, I0.1, etc. - ** Outputs **: Forward Contactor Coils and Reverse Contactor Coils are used as the output devices. They should be connected to the corresponding output terminal of the PC, such as Y000 and Y001 of the Mitsubishi-based PC, Q0.0 and Q0.1 of the SIEMEN-based PC, etc. ** 2. Draw the circuit diagram (Take the three-phase induction motor as an example)** 1. ** Main circuit part ** - The three-phase power supply was connected to the fuse (for short-circuit protection) and then connected to the main contact of the contactors. For forward rotation, when the main contact of the forward rotation contactors (KM1) is closed, the three-phase power supply is connected to the motor according to the normal phase sequence, and the motor is rotated forward. For reversal, when the main contact of the reversal contactors (KM2) is closed, the phase sequence of two phases of the three-phase power supply is reversed and then connected to the motor, and the motor is reversed. At the same time, the thermal relay (FT) should be connected to the circuit to detect the current of the motor and automatically cut off the circuit when overloaded. 2. ** Control Circuit ** - ** Forward control circuit **: Lead out from one end of the power supply, first connect the stop button (normally closed), then connect the forward start button (normally open) and the auxiliary normally open contact (for self-locking) of the forward rotating contactors (KM1) in series, then connect the auxiliary normally closed contact (for interlocked) of the reversing contactors (KM2) in series, and finally connect to the coil of the forward rotating contactors (KM1). The other end of the coil returns to the other end of the power supply. - ** Reverse control circuit **: It is also led out from one end of the power supply. First, connect the stop button (normally closed), then connect the reverse start button (normally open) and the auxiliary normally open contact of the reversing contactors (KM2) in series (for self-locking), then connect the auxiliary normally closed contact of the forward rotating contactors (KM1) in series (for interlocked), and finally connect to the coil of the reversing contactors (KM2). The other end of the coil returns to the other end of the power supply. - ** Overload protection part **: The normally closed contact of the thermal relay (FT) is connected in series to the common part of the control circuit (i.e. behind the stop button). When the motor is overloaded, the thermal relay will act, and the normally closed contact will be disconnected, cutting off the entire control circuit. ** 3. Draw the ladder diagram (Take the SIEMens's PL as an example)** 1. ** Forward Rotation Control Logics ** - I0.0 is used as the input signal of the forward start button, I0.1 is used as the input signal of the stop button, I0.2 is used as the input signal of the reverse start button (all are normally open contact input), Q0.0 is used as the output signal of the forward contact coil, and Q0.1 is used as the output signal of the reverse contact coil. - When I0.0 is pressed (the normally open contact is closed) and I0.1 is not pressed (the normally closed contact is closed) and Q0.1 is not energized (the normally closed contact is closed), Q0.0 is energized and self-locked (the normally open contact of Q0.0 is closed to maintain its energized state). - In the ladder diagram, it is represented as: the normally closed contacts of I0.0 and I0.1, the normally closed contact of Q0.1 are connected in series to the coil of Q0.0, and the normally open contact of Q0.0 is connected in parallel with I0.0 to achieve self-locking. 2. ** Reverse control logic ** - When I0.2 is pressed (the normally open contact is closed) and I0.1 is not pressed (the normally closed contact is closed) and Q0.0 is not energized (the normally closed contact is closed), Q0.1 is energized and self-locking. - In the ladder diagram, it is represented as: the normally closed contacts of I0.2 and I0.1, the normally closed contact of Q0.0 are connected in series to the coil of Q0.1, and the normally open contact of Q0.1 is connected in parallel with I0.2 to achieve self-locking. The specific instructions, component representation, and programming rules of different brands of PDLCs (e.g., Samsung, SIEMENS, etc.) may differ, but the basic control logic and design ideas are similar. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
