In industrial equipment, it is usually called power control panel, which can be divided into intermediate frequency power control panel and high frequency power control panel. The control panel of intermediate frequency power supply is usually connected to the thyristor intermediate frequency power supply, which is used in cooperation with other intermediate frequency industrial equipment, such as intermediate frequency electric furnace, intermediate frequency quenching machine tool and intermediate frequency forging. The high frequency control board used in high frequency power supply can be divided into IGBT and KGPS. Because of energy saving, IGBT high frequency board is widely used in high frequency machine. Common industrial equipment control panels include: CNC stone carving machine control panel, plastic setting machine control panel, liquid filling machine control panel, adhesive die cutting machine control panel, automatic drilling machine control panel, automatic tapping machine control panel, positioning labeling machine control panel, ultrasonic cleaning machine control panel, etc. Control system: understood as a device composed of multiple control panels, it is a control system; If three people form a group and three computers are connected together, a network is formed. The composition of the control system is that the operation between devices is more convenient, the production equipment is automated, the operation of personnel is saved, and the productivity and efficiency of enterprises are improved. The control system is applied to the following industries: industrial Internet of Things control system, agricultural Internet of Things control system, large toy model controller, man-machine interface control system, greenhouse intelligent temperature and humidity controller, water and fertilizer integrated control system, PLC non-standard automatic test equipment control system, smart home control system, medical care monitoring system, MIS/MES workshop automatic production control system and so on.
