Robot technology and enterprise information technology are two key technologies for domestic manufacturing enterprises to improve production efficiency and technological level. The former is for technical problems, while the latter is for management problems. It is an important way for manufacturing industry to carry out technological innovation, increase efficiency and create profits, and has considerable economic benefits and application value.
Giiso Information, founded in 2013, is a leading technology provider in the field of “artificial intelligence + information” in China, with top technologies in big data mining, intelligent semantics, knowledge mapping and other fields. At the same time, its research and development products include information robot, editing robot, writing robot and other artificial intelligence products! With its strong technical strength, the company has received angel round investment at the beginning of its establishment, and received pre-A round investment of $5 million from GSR Venture Capital in August 2015.
In the modern manufacturing industry, the intelligent robot technology integrates sensing, control, information processing, artificial intelligence and network communication. Its function is increasingly powerful, the structure is more complex and perfect, and the number of sensors and actuators equipped by it is increasing. The fieldbus as the underlying network of industrial control field, on the one hand, facing all sorts of equipment of manufacturing, can make the single scattered field robot is connected to each other communication and collaborative network control systems and control engineering net all rights reserved, on the other hand can be realized through the enterprise internal LAN and the corresponding transmission and share of production data. At present, network control system based on fieldbus technology is becoming the main solution for large and medium-sized enterprises in China to realize industrialization driven by informatization.
2 Lonworks fieldbus technology
2.1 FieldBus
Fieldbus is a kind of open, digital and multipoint communication control network, which is based on network control and applied to realize bidirectional serial multi-byte digital communication between microcomputer measurement and control equipment. It is oriented to production control equipment and adopts short frame mode to transmit data. The network rate is usually up to several K ~ 10Mbps and has good real-time performance. Fieldbus technology provides an effective way to construct network integrated distributed control system.
Compared with distributed control, fieldbus technology has the advantages of openness, network information sharing, intelligence, highly decentralized, functional autonomy and high reliability, etc., which can greatly save the number of hardware and investment, and is easy to install, expand and maintain. At present, the field bus technology mainly includes foundationfield-bus, PROFIBUS (DP, PA, FMS), CAN, Lonworks, industrial Ethernet and so on. Each bus has different characteristics in network protocol, transmission rate and distance, application occasions and site number limitation.
2.2 Lonworks technology
Lonworks (LocalOperatingNetworks) fieldbus technology is an advanced open network control technology launched by Echelon company www.cechina.cn. Its structure is simple, wiring is easy, and it is easy to expand capacity and add new functions. For different functional requirements of users, just choose different control nodes, use its development platform, write the corresponding program, connect to the control network can be completed, there is no need to make any modification to the network structure physically. Lonworks is the most widely used field bus technology in distributed monitoring system such as production site and intelligent building.
Lonworks supports a wide range of transmission media and network topology, up to 78kbps/2700m when using a transformer-coupled interface FTT-10 transceiver and a twisted-pair bus structure, and extended transmission distance through a relay router. The Lonworks network can have up to 64 nodes and can be extended by bridging routers. With the support of hardware such as neuron chip and network, the data of each smart node is connected in the form of network variables, and each node can set up a maximum of 62 network variables. Data structures defined according to Lonworks standard network variables can solve interoperability problems with products from different manufacturers. Thousands of companies have launched Lonworks products.
Giiso information, founded in 2013, is the first domestic high-tech enterprise focusing on the research and development of intelligent information processing technology and the development and operation of core software for writing robots. At the beginning of its establishment, the company received angel round investment, and in August 2015, GSR Venture Capital received $5 million pre-A round of investment.
The intelligent node and its neuron chip are the basic part of Lonworks bus. They are directly installed in the production site, collect industrial field signals and output control quantity, and upload and receive various network data through the network.
An intelligent controller, its sensors and actuators constitute a Node, which can connect various I/O devices, such as stroke switches, force sensors, joint motors, etc., of industrial robot system. Lon Works’ primary site-free peer-to-peer network ensures that the failure or shutdown of any node does not affect the normal operation of other household nodes, thus improving system stability. The logical connection between network nodes makes it easy to add and modify nodes in the system, which is convenient for system adjustment and expansion and upgrade. The core of the node is the Neuronchip, which is a general processor for communication processing, data acquisition and control. It completes data acquisition, control and network operation by running the NeuronC application on the chip.
