Automation is a major that integrates macro vision into a larger field. In fact, the regeneration of electricity and gas involves many aspects, but you can't observe it. 1. In terms of transportation, electrified railway roads, such as light rail, subway, railway and maglev trains, including most of the trains now, are automatically controlled by electrification. \x02 Aircraft, satellite launch, launch, etc. In the sky. 2. All fields such as industry, petroleum, chemical industry, electric power and production. Mainly rely on gas and electricity automation for operation, production, processing, supervision, control and maintenance. For example, coal-to-liquid production, hydrogen production from coal, coal-fired power generation, steel production in fertilizer plants and refineries, various automatic and semi-automatic production lines, steam car production, processing, packaging, transmission, oil production in oil fields, daily operation and maintenance of natural gas, remote monitoring and program control, remote control systems, etc. , basically need to use electrical and air professional knowledge. 3. Civil alarm, 3. Civil alarm, fire alarm system, HVAC system, security system, automatic processing, power distribution system, power supply system, banking system, including our usual credit card system, etc. All knowledge of electrical automation must be used.
