The traditional order of production of automobile production line is difficult to fill in on flexibilityFoot highly customized requirements, and customized production cycle longer. 5G What are typical applications of Intelligent Manufacturing Why do we need to know what is the wireless communication intelligent manufacturing, intelligent manufacturing processes obvious cloud platforms and factory production facilities, real-time communication and information exchange platform for mass sensors and artificial intelligence in the smart manufacturing, and people efficient machine interface interaction, there are diverse needs of the most demanding performance requirements and the communication network, and the need to introduce highly reliable wireless communication techniques. High reliability of wireless communication technology in view of the plant, on the one hand, manufacture of the wireless device such that flexible manufacturing and modular production plant becomes possible. On the other hand, because the wireless network can build factories and production lines, renovation construction more convenient, and can reduce the amount of maintenance work to reduce costs by wireless. What are the challenges facing the wireless communication network in the intelligent manufacturing applications in intelligent manufacturing automation and control systems, low-latency applications is particularly widespread, such as sensitive high-precision manufacturing sectors of environment, hazardous chemicals and other production processes. Intelligent Manufacturing System loop control sensor (e.g., pressure, temperature, etc.) of the information needs to be acquired by a low latency transmission network, the data needs to be passed to the final implementation of the system components (such as: manipulator, electronic valves, heaters, etc. ) to complete the high-precision control of production operations, and requires high reliability throughout the network, to ensure the safe and efficient production process. In addition, factory automation systems and the operating range of the sensor system may be square to tens of thousands or hundreds of kilometers, and may even be distributed deployment. The different production scenarios, there may be thousands of sensors and actuators manufacturing facility production area, the network need to communicate massive connectivity as a support. 5G networks have the ability Huawei took the lead in Beijing Huairou completed by the IMT-2020 (5G) advance group of Chinese organizations 5G wireless technology R & D testing second phase of testing. In the test session in C-Band, a 200MHz bandwidth and tested by the new air interface and mass 5G MIMO technology, a peak exceeding 20Gbps cells, the air interface delay 0.5ms or less, greater than 10 million single-cell connection. And compared to the conventional mobile communication technology, 5G will further enhance the user experience: in terms of capacity, 5G 4G communication technology than the moving area per unit 1000-fold growth in data traffic; transmission speedRates, the typical single user data rate increased by 10 to 100 times, the peak transfer rate up to 10Gbps (100 times the rate of the 4G network); 5-fold shorter-end delay; in terms of accessibility: networked device may the increase in the number of 10 to 100 times; reliability and power consumption: energy per bit consumption should be reduced to one thousandth, low-power 10-fold increase in battery life. Typical application scenarios 5G 5G manufacturing industry AR enabled applications in the future intelligent plant production process, it will play a more important role. However, due to the factory of the future with a high degree of flexibility and versatility, which will have the factory floor staff have higher requirements. To quickly meet the needs of new tasks and production activities, augmented reality AR will play a very key role in the intelligent manufacturing process can be used in the following scene: such as: monitoring processes and production processes. Production tasks step by step guidelines, such as manual assembly process guidance; remote expert support services, such as remote maintenance. In these applications, AR auxiliary facilities have required the greatest degree of flexibility and portability to effectively carry out maintenance work. It is necessary to move the cloud on the device information processing function, AR device only includes a display function and is connected, AR Drive device and a wireless network connection. The AR device acquired in real time through a network the necessary information (e.g., CONTROL ENGINEERING China Copyright , production data, equipment data, and fault handling instructions). In this scenario, the display content AR glasses must be synchronized with the movement of the camera in the AR device, in order to avoid the step-out phenomenon of the visual range. The reaction time is less than normal from the visual image moves to the AR 20ms, then there will be good synchronization, it is required to transfer data cloud from the camera to the display content of the cloud to AR is smaller than the required return 20mms, to remove the cloud and screen refresh process extension, you need two-way transmission delay of the wireless network in 10ms to meet the needs of real-time experience. And the delay requirements, LTE network can not meet. 5G wireless enabled factory automation control automation control , the inverted pendulum is a typical application. Inverted pendulum robot various principles for attitude control, aviation spacecraft docking control, attitude control and other industrial applications. Huawei X Labs PENDULUM 5G of extremely low test by automatically invertedValue control, research shows that when the pendulum run in 4G mode, high latency 4G, making the inverted pendulum control command can not be performed quickly, placed upside down steady swing for too long, to reach 13.2 seconds . When operating in mode 5G, 5G 1ms ultra low latency of the control command to quickly perform a pendulum Copyright Control Engineering , from the steady state placed only 4 seconds. By contrast, low latency network 5G can see great value in automatic control, reduce network from end to end delay of 50ms 4G to 1ms 5G of. Manufacturing plant automation and control is the most basic applications, the core is a closed loop control system. Each sensor in the continuous measurement period of the control system, measurement data to the controller to set the actuator. A typical closed loop control process ms low level period, the communication system needs to reach latency ms or even lower-level control system to ensure precise control, while also high reliability requirements. If due to an error in the production process delay is too long, or control information occur when data transfer can lead to production downtime can cause significant financial losses. Further, in production scale plant, a large number of production processes are used in automatic process control, it will have a high density mass controllers, sensors, actuators require a wireless network connection. Different applications, the number of sensors, the control cycle delay requirements, bandwidth requirements are differences in closed-loop control system, typically run CONTROL ENGINEERING China Copyright , some typical values of the cycle time and communication bandwidth size as follows: 5G prolonged slice network providing low, high reliability, mass network connection, such that the closed-loop control applications is made possible by a wireless network connection. 5G, capacity based Huawei Found: the air interface delay may be 0.4ms, single cell downlink rate reached 20Gbps, maximum support 10 million cells + the number of connections. Thus, the mobile communication network only 5G network can meet the requirements for closed-loop control of the network. 5G enable cloud of factory robots in intelligent manufacturing scenario, the robot needs to have the ability to self-organization and collaboration to meet flexible production, which has created a need for a robot of the cloud. And compared to the conventional robot, the robot needs cloud of a network connection to the control center of the cloud, based on ultra-platform computing power, and throughAnd AI data is too large for real-time manufacturing process control operation. By a lot of computing cloud robot functions and data storage functions to move the cloud, which will greatly reduce the hardware cost of the robot itself and power consumption. And to meet the needs of flexible manufacturing, the robot needs to meet the requirements of freely movable. Therefore, in the process of the robot cloud, the wireless communication network needs to have a low latency and high reliability features. 5G network is a cloud robotics ideal communication network, the key is to make robots capable of clouds. 5G slice network can provide end to end customized network support for cloud robotics applications. 5G network may reach the end of the communication delay as low as 1ms, and supports the connection reliability of 99.999% CONTROL ENGINEERING China Copyright , a powerful network capability can greatly satisfy the cloud delay and robotics reliability challenges. Huawei has been with the German intelligence cooperation in the field of manufacturing and manufacturing enterprises. The co-operation of the robot on cloud-based web sections 5G and Festo, project through 5G uRLLC (ultra low latency and reliable communication) network sections, for the cloud robot closed loop control system of high reliability and to meet the degree of real-time carry out testing. The robot trajectory information and control data in a manufacturing process contributes to the cloud computing system and robot platform extension saving ability. With a robotic production services and manufacturing means that the cloud of the basic functions of industrial robots and high-performance computing systems for real-time collaboration, 5G slice of this network enabled application scenarios. Communication needs between the robot and collaboration in intelligent manufacturing flexible production facilities, the mobile robot is a key enabler. Require multiple coordinated movement and collision-free operation between the robot in the production process, so the need for real-time data exchange between the mobile robot to meet this need. Between the mobile robot and peripheral devices also need to communicate. For example, CONTROL ENGINEERING China Copyright , such as a crane or other manufacturing facility.
