Please tell me what systems are available in the digital manufacturing industry?

1. Automated control system: The automated control system includes sensors, actuators, controllers and communication networks, which are used to monitor and control production equipment and processes in real time.They can realize automated operation, adjustment and optimization to improve production efficiency and quality.

2. Digital manufacturing involves multiple systems and technologies. The following are some common systems: MES (Manufacturing Execution System): MES system is used to monitor, coordinate and manage production processes in real time, including production scheduling. , operation guidance, quality management and equipment monitoring and other functions.

3. Digital production scheduling system: Through digital technology and intelligent control, realize the digital management and intelligent control of production planning and scheduling, and improve production efficiency and management efficiency.

4. In management, the intelligent manufacturing systems that can be used are: PLM, CRM, SRM, ERP, BI, etc.At the execution layer, the intelligent manufacturing systems that can be used are: APS, MES, QMS, WMS, EMS, EAM, LES, etc. In the control layer, the intelligent manufacturing systems that can be used include: PLC, DNC, SPC, etc.

What are the systems of digital intelligence?

1. Automated control system: The automated control system includes sensors, actuators, controllers and communication networks, which are used to monitor and control production equipment and processes in real time. They can realize automated operation, adjustment and optimization to improve production efficiency and quality.

2. Internet of Things system (IoT): The Internet of Things system connects sensors, devices and networks to realize data interaction and remote monitoring between devices. In digital manufacturing, the Internet of Things system can be used to monitor the status of equipment in real time, optimize equipment maintenance and improve the visibility of the production process.

3. In management, the intelligent manufacturing systems that can be used are: PLM, CRM, SRM, ERP, BI, etc. At the executive level, it canThe intelligent manufacturing systems available include: APS, MES, QMS, WMS, EMS, EAM, LES, etc. In the control layer, the intelligent manufacturing systems that can be used include: PLC, DNC, SPC, etc.

What is a digital communication system and what are its types?

1. Digital communication is a communication method that uses digital signals as a carrier to transmit messages, or uses digital signals to digitally modulate carrier waves before transmitting them. It can transmit digital signals such as telegrams and digital data, as well as analog signals such as digitally processed voice and images.

2. Digital communication systems can be further subdivided into digital frequency band transmission communication system, digital baseband transmission communication system, and analog signal digital transmission communication system.The basic feature of digital communication is that its messages or signals have "discrete" or "digital" characteristics, so that digital communication has many special problems.

3. The purpose of the basic model communication of the communication system is to deliver messages. Messages include symbols, text, speech, music, pictures, data, images and other forms. Basic point-to-point communication is to pass messages from the sender to the receiver through a certain channel. The basic model description of the communication system is shown in Figure 1.

4. Hello, digital communication services include: wireless paging services. This is a one-way communication service, which has two types of systems: public and dedicated. Mobile phone business. The business of using mobile phones to make calls to each other through base stations and automatic switching devices.

5. Classification of digital communication systemDigital band transmission communication system The basic feature of digital communication is that its messages or signals have "discrete" or "digital" characteristics, so that digital communication has many special problems.

6. The channel is the transmission medium of the transmission signal, and the message is the receiver of the information, which corresponds to the source. The function of the receiving device is the opposite of that of the sending device. The received signal is processed and transformed. The noise source is the concentrated performance of the noise in the channel and the noise scattered in other parts of the communication system.

What is a digital system

1. A digital system is a circuit that uses digital signals to complete arithmetic and logical operations on digital quantities, called a digital circuit, or digital system.

2. Binary: Binary is a digital system with a base of 2, which contains only two numbers, 0 and 1. It is used for data representation and processing inside the computer, because the computer uses switches (on and off, or representing 0 and 1) to store and process information.

3. Arabic numerals were originally invented in ancient India. Arabic numerals modified by Westerners or Europeans. The Arabic numeral system was first invented by the Arab Brahmis, and then introduced to the West by Arabia.

4. Digital receiving system: Digital receiving system refers to a system that converts analog signals into digital signals. It includes digital receiving system and digital receiving system. Digital signal processing system: Digital signal processing system refers to a system that processes digital signals. It includes digital signal processing system and digital signal processing system.

What are the six links of the digital communication system?

Baseband transmission system: Baseband transmission system refers to a system that transmits digital signals directly to the channel without modulation. It includes digital baseband transmission system and digital baseband transmission system. Digital modulation system: Digital modulation system refers to a system that converts digital signals into analog signals and then transmits them to the channel.

The data communication system is mainly composed of three parts: central computer system, data terminal equipment (DTE) and data circuit.

The communication system is roughly composed of three parts: the transmitter (sending source and sending device), the channel receiving device (the receiving device), and the noise source. The source is the source of information, and its function is to convert the original signal into the corresponding electrical signal, that is, the baseband signal.

It is generally composed of a signal source (sending device), a signaling device (receiving device) and a channel (transmission medium), etc., which are known as the three elements of communication.
