1,The concept of smart Internet of things?
At present, the Internet of things of construction machinery is widely used. With the help of global positioning system, mobile phone communication network and Internet, it realizes the intelligent identification, positioning, tracking, monitoring and management of construction machinery, so as to make the construction machinery, operators, technical service engineers, agency stores and manufacturers “connected with things, everyone and things and people” in different places, remote, dynamic and all day.
The current development orientation of the Internet of things is to improve the original Internet of things service of construction machinery from “information collection service” to “data consulting service”. From the original on-site management to remote monitoring, from traditional manufacturing to manufacturing service, from the original passive service to active service. Functional design includes information management, behavior management and value management.
Information management includes regional operation intensity management, fault early warning and remote diagnosis, vehicle operation and maintenance active service, financial mortgage security service.
Behavior management includes statistical management of operators, efficiency analysis of working hours, behavior and efficiency analysis, operation specifications and efficiency analysis, etc.
Value management includes product life cycle cost management, behavior and employee performance management, multi-dimensional big data decision support, etc.
Taking the agricultural machinery information management platform as an example, it can carry out global GPS positioning, vehicle locking, vehicle unlocking, equipment man hour query, fault alarm and other operations for relevant machinery vehicles required by agriculture, which plays a vital role in promoting agricultural production and improving work efficiency.
2,What are the differences between the Internet of things and the Internet?
First, the coverage of the Internet of things is greater than that of the Internet. The Internet and the Internet of things can be distinguished from each other in terms of their main functions. The Internet is the future where people exchange information through the network, and the service subject is people. The Internet of things is born for things, mainly to manage things, let things exchange information independently and indirectly serve people.
Second, Internet users access Internet resources through servers, desktops, notebooks and mobile terminals, while sensor nodes in the Internet of things need to access the Internet through the sink node of wireless sensor networks. Therefore, the access methods are different. The Internet of things application system will select wireless sensor network or radio frequency identification (RFID) application system to access the Internet as required. The Internet needs people to operate themselves to get the corresponding data, and the data of the Internet of things is automatically read out by sensors or readers.
Third, the Internet of things involves a wider range of technologies. Internet of things application technology mainly includes wireless technology, Internet, intelligent chip technology and software technology, covering almost all fields of information and communication technology. The Internet is only a technical direction, a virtual communication, and the Internet of things is the communication between physical objects. Therefore, the application prospect of the Internet of things is far greater than that of the Internet.
3,Application of Internet of things in power production?
(1) Material field. For example, the Internet of things platform for manufacturing equipment can control the quality and progress of suppliers’ production links, connect internally with ERP and ECP, and provide platform support for quality control, service collaboration, data mining and value creation between the supplier and the demander.
The contents can include: real-time collection of supplier production, detection and equipment information in the whole process, automatic monitoring and early warning of the manufacturing process according to the set parameter values, creating a “Transparent Factory”, and reducing the cost of qualification performance verification, factory supervision and witness in the traditional sense.
(2) Production field. For example, the monitoring and inspection of substation safety production. First, for the on-line monitoring of equipment status, the equipment status is monitored in real time through wireless sensors, and early warning is carried out according to the specified threshold; The second is to control the operation site, remotely monitor the key links of production operation, and eliminate illegal operation.
