What are the components of the microreaction experimental setup?

1. Uses and characteristics:

The fixed-bed micro-reaction experimental device is an automated micro-experimental device controlled by a programmable controller and a computer. The device is operated automatically, and the temperature, flow, pressure signal and detector signal of each operation point are automatically collected by the system, and the parameter changes in the reaction process are displayed in real time through the computer. By setting the temperature and flow values through a computer system, the operator can automate the operation of the unit.

According to different requirements, the reaction pressure of the device can be adjusted by automatic control of the back pressure valve. It can be used for the evaluation of catalysts at high temperature and high pressure or at high temperature and pressure, and the device is equipped with a high-pressure and atmospheric gas supply system and a high-pressure and atmospheric solid-gas conversion (sulfur into sulfur vapor) system. A certain amount of catalyst is placed in the reactor and the performance of the catalyst is continuously tested for a long time under specific process conditions.

The core process components of the plant such as reactors, solid-gas conversion evaporators, condensers, and high and low pressure separators; The instrumentation of the device such as pressure reducing valves, back pressure valves, gas mass flow meters, sulfur vapor meters and pipe valves can ensure the stability, reliability and safety of use.

First, the basic structure of three parts:

Microprocessors, (memory, I0 interface, system bus) peripherals.

Power supply. 2. Microcomputer is a bare metal based on microprocessor, equipped with internal memory, input-output (I0) interface circuit and corresponding auxiliary circuit. The integration of a microcomputer on a chip constitutes a monolithic microcomputer. A complete microcomputer system consists of two parts: the hardware system and the software system.

The hardware system consists of combinators, controllers, memory (including memory, external memory and cache), and various input and output devices, which work in a "instruction-driven" mode.

3. Microcomputer software systems include two categories: system software and application software.

System software, system software is used to manage and coordinate the hardware of various parts of the microcomputer, such as CPU, memory, and various peripherals, so that they work in an orderly and efficient manner.

Application software, application software is for different applications, to achieve the user requirements of the function software, for example, the Internet network on the web page, the MIS program of each department, the application software in CIMS and the monitoring and control process in the production process.

A complete computer system consists of two parts: the hardware system and the software system. Computer hardware is mainly composed of five parts: combinators, controllers, memory, input devices, and output devicesHardware provides the material medium of a computer system.

Computer software includes two categories: system software and application software. Software mainly refers to the programs that are required to allow a computer to accomplish various tasks.

The design principle of the computer is based on the design idea of "program storage and program control" put forward by the American-Hungarian scientist von Neumann, and at the same time points out that the composition of the computer includes the following three aspects:

1) The computer system is composed of five basic components: combinator, memory, controller, input and output equipment, and the basic functions of the five components are specified.

2) The computer should use binary to represent data and instructions.

3) Program storage and program control.

The microcomputer system is composed of two parts: the hardware system and the software system, which is a computer system composed of a microcomputer, a display, an input and output device, a power supply and a control panel. It is equipped with an operating system, a high-level language, and a variety of tools. It is a modern electronic device that can process information automatically, at high speed and with precision.

Computers have the ability to perform arithmetic operations and logical judgments, and can automatically complete the processing of data through pre-programmed programs, so it can also be said that computers are also a tool that helps humans engage in mental work (including thinking activities such as memory, calculation, analysis, judgment, design, consultation, diagnosis, decision-making, learning and creation).

The main features of the microcomputer system:

1. Simple structure, flexible system design and strong adaptability.

2. Small size, light weight and low power consumption; Due to the widespread use of large-scale and ultra-large-scale integrated circuits in microcomputers, the volume of microcomputers has been greatly reduced.

3. High reliability and low environmental requirements due to the use of large-scale and ultra-large-scale integrated circuits in the microcomputer, the number of devices used in the system is reduced, the number of connections between devices and components and the number of connectors is also reduced accordingly, and the power consumption required for the work of the MOS circuit itself is also very low, so the reliability of the microcomputer is greatly improved.

The microcomputer system is mainly composed of: microprocessor, main memory, input and output interfaces.

1.What are the disadvantages of combinatorial logic controllers, and how microprogram controllers have modified them to address these shortcomings.

Enter? (p140)

A: The disadvantages of combinatorial logic controllers are:

The design is irregular, and the design efficiency is low; The core structure of the controller is scattered, which is not convenient for inspection and debugging.

It is not easy to modify and extend the functions of the command system.

Improvements: Introduced procedural techniques to make the design regular;

Storage logic is introduced to make the functionality easily extensible.

2.What is the basic idea of microprogram control?

Answer: Several micro-commands are programmed into a micro-instruction, and the control realizes one-step operation;

A number of micro-instructions form a micro-program that interprets and executes a machine instruction;

The microprogram is stored in the control memory in advance and then removed when the machine command is executed.

3.This briefly describes what is stored in control memory and how it differs from main memory.

A: The microprogram is stored in the control memory.

Difference from Mainstream:

Control memory in.

CPU, but the main memory is not;

Control memory is one.

rom, and the main memory is.

rom and. RAM control memory is smaller than main memory.

Control memory word length is longer than main memory.

Control memory is faster than main memory.

4.What are the two parts of microinstructions?What are the roles of each?

A: Microinstructions can be divided into:

Micro-command fields (or micro-operation control fields.

and microaddress fields.

or a sequential control field.

Microcommand field: Provides the microcommand required for a one-step operation.

Provide a given portion of the microaddress.

5.What is the principle of grouping microcommands when using the segmented direct compilation method?

Answer: Microcommands that are mutually exclusive in the same type of operation are placed in the same field.

6.What is Functional Transfer?

7.What are the subsequent ways in which microaddresses are formed?
