What are the principles of electrical schematics?
The principles to be followed in electrical schematic diagrams are as follows: 1. Electrical control circuits can be divided into main circuits and control circuits. The main circuit, which includes the circuit from the power source to the motor, is drawn on the left side of the schematic diagram. The control circuit, composed of buttons, coils of electrical components, auxiliary contacts of contactors, etc., is drawn on the right side. 2. Diagram lines representing wires, signal paths, and connecting lines should be straight lines with the least number of crossings or bends. They can be arranged horizontally or vertically. 3. In electrical schematic diagrams, all graphic and text symbols of electrical components must adopt national unified standards. 4. To highlight and distinguish certain circuits, wires and connecting lines can be represented by connecting lines of different thicknesses. 5. The expanded - view drawing method of electrical components is adopted. Different parts of the same electrical component may not be drawn together, but they need to be marked with the same text symbol. If there are multiple components of the same type, a number index can be added as a subscript after the text symbol. 6. All buttons and contacts are drawn in their original states without external force and without power on. 7. The branch circuits of the control circuit are arranged in principle according to the sequence of actions, and the electrical connection points at the intersection of two wires must be marked with black dots.

lens electrical interface
The common electrical ports of the lens were as follows: 1. ** DC-port **: Most cameras have a 5.5*2.1 DC-plug as the power interface. 5.5 refers to the outer diameter of the power plug of 5.5mm (tolerance: 0.05mm), and 2.1 refers to the inner diameter of the plug of 2.1mm (tolerance: 0.05mm). The power plug was positive inside and negative outside, while the positive and negative poles of the camera interface were the opposite. The inside was negative and the outside was positive. The common specifications of the camera's power supply voltage were 12V and 9V. 2. ** tyrannic-c interface **: For the convenience of power supply in home IPCs (network cameras), the tyrannic-c interface, also known as the usb-c interface, was used. Its power supply specifications were 5v/1A. 3. **PoE interface **: PoE power supply is provided through the 1236 or 4578 cores of the network cable (1236 cores transmit data at the same time). The PoE interface is an ordinary network cable interface, so there is no need to provide a separate DC-interface. PoE power supply is divided into standard PoE power supply and non-standard PoE power supply. The standard PoE is in accordance with the IMEE802.3af, and the device supports 1236 and 4578 power supply methods. The non-standard PoE power supply directly provides 12V, 24V, 48V or 54V power supply parameters. Generally, the power supply and equipment are customized and cannot be used at will. Otherwise, it may cause equipment failure or instability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Stories of Wives and Electrical Accidents
A wife might be electrocuted when she tries to plug in a device with wet hands. This is a very common but dangerous mistake. Water conducts electricity, and so the current can easily pass through her body, causing harm.
The protagonist communicating with electrical appliances
There were two novels where the protagonist could communicate with electrical appliances. The first book was " Trash Man ". The protagonist, Zou Hao, obtained superhuman abilities through electrical appliances and could communicate with the electrical appliances in his home. The second book was " I Can Understand Everything." The protagonist could understand the words of electrical appliances, and after discovering that he could understand the language of all things, he began a series of stories. Both novels provided the plot of the protagonist communicating with electrical appliances.
What does an electrical device reflect? What is the power consumption and power of an electrical device?
The power of an electrical device reflected the speed at which it consumed electricity. The power value was equal to the electrical energy consumed by the electrical device in 1 second, and its magnitude was equal to the product of the voltage at both ends of the conductor and the current passing through the conductor (P = U×I). Power consumption was measured in kWh, commonly known as degrees. It represented the amount of electricity consumed by a 1,000-Watt electrical device for one hour, which was one degree of electricity. Through the power of the electrical appliances, the power consumption in a certain period of time could be calculated. For example, if an electrical device with a power of 1 kilogram was used for 1 hour, the power consumption would be 1 kWh. Different types of electrical appliances have different power ranges, and their power levels determine how much power they consume for the same amount of time. For example, high-power appliances consumed more power than low-power appliances in the same time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Computer Principles
Computer principles covered many aspects: ** 1. Basic operation mode of the computer ** 1. ** The three steps of hardware input, calculation, and output ** - Computer hardware was made up of a large number of integrated circuits (IPs), and the pins of the IPs were used for input and output. The normal operation of a computer required three steps: input, operation, and output. First of all, the computer itself could not generate information and needed external data (input). Second, the computer had to process and calculate the input data (operation), which was its core value. Finally, the processed data had to be displayed (output) so that the user could know the result. These three steps were closely linked and were indispensable. 2. ** The Essence of Software-A Collection of Orders and Data ** - The essence of a program was a collection of instructions and data, and it had nothing to do with the complexity of the program. An instruction was a command that controlled the computer to input, calculate, and output. The data in the program is divided into input data that is the object of instruction execution and output data that is obtained from the result of instruction execution. For example, in a personal computer, the content of an executable program file with the.Exe extension was a list of values. Each value was either an instruction or data. 3. ** The difference between computer processing and human thinking habits ** - The computer used numbers to represent all information, which was different from human thinking habits. For example, humans used "blue" and "red" to describe colors, while computers used numbers. For example,"0,0,255" represented blue, and "255,0,0" represented red. The computer would first convert the text into the corresponding numbers (character codes) before processing. ** 2. Computer structure composition ** 1. ** Internal and External Storage ** - The internal and external memory was a component that realized the memory function. It was used to store the calculation program and various data involved in the calculation. 2. **CPU structure and functions ** - ** Arithmetic Unit **: It is composed of an arithmetic logic unit, ALU, general purpose register, and data temporary register. The program status word register accepts the commands of the controller and performs actions. It is responsible for the processing and processing of data, namely the arithmetic and logic operations of data. - ** Controller **: Composed of program counter PC, instruction register AR, address register AR, data register Dr, instruction translator, etc. It is responsible for analyzing the control information specified by the program, controlling and coordinating input and output operations or memory access. - ** Register Group **: The register function is to store the binary-code. It is composed of flip-flops with storage function. Registers, buffer, and memory were in close proximity to the CPU. The closest to the CPU was the register, then the buffer, and finally the memory. When the CPU operated, it first read the data from the hard disk into the memory, and then read the data that was about to be used into the register. The CPU prioritized reading and writing the register, and then the register exchanged data with the memory. The buffer existed between the register and the memory, because frequently manipulating the same address data in the memory would affect the speed, and the extraction speed from the buffer was much faster than the memory. - ** bus **: It is the common channel for the CPU, memory, input and output devices to transmit information. The components of the host are connected through the bus, and the external devices are connected to the bus through the corresponding interface circuit. ** 3. Concepts related to commands and programs ** 1. ** Command ** - An instruction was the smallest unit of program control for a computer. The collection of all instructions was called the computer's instruction system. 2. ** Program ** - A program is a set of instructions written in a certain language to complete a specific task. ** 4. Concepts related to the finite-state machine ** 1. ** Basic Concepts ** - The finite-state machine (FSM) was also known as the synchronous finite-state machine. All the state jumps were performed under the effect of the clock, and the number of states was limited. Each state represents an event, and going from one event to another is called a state jump or transition. 2. ** Constitution and expression ** - It is composed of a state register group and a combination logic circuit. The state register group has k bits, that is, there are k state register, and the state is encrypted into k bits, which can represent multiple unique states. The input has m bits and the output has n bits. The trigger condition for a state change is the arrival of the rising edge of the Clock signal. According to whether the output is related to the input conditions, it can be divided into Moore state machines (the output of the combination logic only depends on the current state and has nothing to do with the input state) and Mealy-type state machines (the output depends not only on the current state but also on the input state).
