Embodiment Construction

[0027] The technical solution will be further described in detail below in combination with preferred embodiments according to the drawings in the description.

[0028] like figure 1 As shown, the Profibus fieldbus type electric actuator controller mainly includes five parts: power conversion unit, power management unit, central processing unit, signal processing unit and power control unit.

[0029] The power conversion unit converts the input 380VAC into two sets of 24VDC and 5VDC power supplies, and supplies power to the signal processing unit and the central processing unit through the power management unit; the power management unit mainly completes the switching of the power supply mode with or without external power input , and provide a charging circuit to charge the backup battery when there is a power supply. When the actuator is powered off, when the local manual operation is performed, the micro switch is turned on, and the central processing unit, signal processin...

Abstract

The invention discloses a profibus filed bus type electric actuating mechanism controller. The controller comprises: a power supply conversion unit, which is used for conversion between an external alternating current power supply and a system power supply; a power supply management unit, which is used for switching of power supply modes and charging management of a backup battery; a signal processing unit, which is used for collection and output of information; a power control unit, which uses a three-phase motor positive and reverse rotation controller as a main part and is used for drivingthe mechanism to make motions; a central processing unit, which is connected with the power supply conversion unit, a power management unit, a signal processing unit, and a power processing unit and is used for managing various control signals; a redundant Profibus communication interface, which is used for make communication with an upper-level monitoring system; a serial port and a port; besides, the serial port and the port are used for uploading and downloading of debugging information. According to the invention, the above-mentioned design scheme enables reliability and availability of an electric actuating mechanism based on a Profibus bus protocol to be substantially improved.

Description

technical field [0001] The electric actuator can be widely used in the automatic adjustment of the production process in metallurgy, petroleum, power station, chemical industry, light textile and other industrial sectors. The invention belongs to the technical field of industrial control network, in particular to a field bus type digital electric actuator. Background technique [0002] The electric actuator is one of the three main instruments in the field of automation, and is widely used in the automatic adjustment of the production process in the electric power, metallurgy, petrochemical and other industries. With the application of field bus and industrial Ethernet in the field of industrial control, networking, bus and intelligence have become the development trend of automation instruments represented by electric actuators. The controller of the electric actuator is the core component of the electric actuator, and completes various control functions of the electric ac...
