Briefly describe the functions of each part of the computer hardware system

1. The computer is a hardware system (hardware system) It is mainly composed of 6 basic hardware parts, namely power supply, memory, CPU, hard disk, motherboard and monitor.

2. Output equipment: print or display the computer's calculation results or intermediate results. Commonly used output devices include: monitors, printers, plotters and fax machines, etc. Memory: The memory stores the information received by the input device in the form of binary data in the storage computer hardware system storage.

3. Operator Operator is a component for arithmetic and logical operations. Controller The controller is a component that realizes the connection of various parts of the computer and the automatic execution of programs. Its function is to extract commands from the memory in turn, generate control signals, send instructions to other components, and direct the whole operation process.

slit system and unit

The seam unit refers to the fluid power unit composed of one or more karst holes connected by a crack network and has a unified pressure system and a hydrodynamic system. Yuan, with the eroded holes, holes and seams as the main storage space and seepage channels, surrounded by a relatively dense or poorly permeable barrier (body).

SystemThere is a continuous dense body segmentation between the system, and the boundary of the crevice system represents the karst action and the related crack boundary. The oil and gas reservoir accumulation of the seam system has the characteristics of "unified temperature-pressure system, large-area oil content, and collective enrichmation of seam reservoirs". The fracture transmission system controls the oil and gas distribution of the seam system.

The underground river single pipeline seam system is an underground river pipeline system with only one main water inlet (with year-round water flow replenishment) and one main discharge port, which is the most basic component unit in the underground river network system. Each branch of the underground river network system is an independent single-pipe seam system.

In the automotive electronic control system, what is the control unit of the famous system?

1. Including the electronic control of the power transmission assembly. The electronic control information communication system of the electronic control body system of the chassis.

2. The automotive electronic control system mainly includes electronic control units (including software), sensors and actuators.

3. Automotive electronic control is divided into three parts, namely sensor, ECU and actuator. Among them, ECU is the control core.

4. The electronically controlled gasoline injection system has an electronic control unit (ECU), which is the core control element of the system. On the one hand, the ECU receives the signal from the sensor; on the other hand, the ECU receives the signal from the sensor. On the other hand, complete information processing and issue corresponding control instructions to control the correct action of the actuator.

5. It is the "heart" of the engine, the gearbox can be understood as the "central system", and the ECU is the "brain" that controls these two systems. If the ECU is broken, the vehicle will definitely be broken. The second function of EUC, safety control, such as the airbag system of the car, must be started by the electronic control unit.

What elements does the microcomputer motherboard system unit consist of

1. The system composed of the CPU and its related devices The core part of the computer is the control center and computing center of the computer. ( 2) The system formed by the bus expansion slot can connect other devices and expand the functions of the computer.

2. The hardware system consists of operators, controllers and memory (includingStorage, external memory and cache), composed of various input and output devices, working in the "instruction-driven" way.

3. A complete microcomputer system includes two major parts: hardware system and software system. The hardware system consists of operators, controllers, memory (including memory, external memory and cache), various input and output devices, and works in a "instruction-driven" way. Software systems can be divided into system software and application software.

4. Host and peripherals. The two major parts of the microcomputer hardware system are the host and the external device. Hardware system refers to the physical devices that make up the computer, such as CPU, memory, floppy disk drive, hard drive, optical drive, main board, monitor, etc. The microcomputer hardware system consists of two major parts, namely the host and the external device.

Briefly describe the working principle of the chassis wire control system control unit

1. Because the "wire" brings "electricity", as the name implies, the wire control chassis can also be understood as "electrically controlled chassis", that is, the original mechanical The realized functions are all controlled by "electricity" on the online control chassis.

2. The driver's control command is converted into an electrical signal and transmitted to the actuator through the human-machine interface to control the action of the actuator; the sensor senses the state of the functional device and transmits it to the human-machine interface through the electrical signal and feedbacks to the driver.

3. The wire control system is the transmission of mechanical energy without mechanical connection between the actuator and the control mechanism. The driver's operating instructions are perceived by the sensor device, and then transmitted to the actuator and electronic controller through the network in the form of electrical signals.

4. Second, the working principle of the electronic control system is the air flow meter and throttle position sensor related to the engine speed sensor. The relevant signals of a series of sensors such as the camshaft position sensor are used to judge the working status of the engine.

5. During the driving process, the information provided by the steering wheel is more accurate and can effectively feedback the driving road conditions. The automotive wire-controlled steering system consists of three main parts: the steering wheel assembly, the steering actuator assembly and the main controller (ECU) and the auxiliary system.

6. At present, only wire-controlled steering can meet the requirements, so it has also become the future development trend of the steering system. Line-controlled system The line-line-controlled system (BBW) is the most difficult but also the most critical technology in online control chassis technology.
