Description

The utility model relates to mechanical engineering, in particular to actuators and actuators controlling pipeline valves (for example, valves or ball valves), and can be used for remote and / or automatic regulation and local control of flows of liquid or gaseous media using equipment, installed on pipelines for various purposes.

Known controller for controlling electrical actuators (RU No. 95866), built into the housing of the electric actuator. The known controller contains electronic components, including a non-contact position sensor of the output shaft of the mechanism, a central processor unit connected to other electronic components and decrypting messages and commands, converting analog signals from the position sensor to digital form, connecting to an external control device, outputting status signals to single LED indicators, mechanical position indicator, connected through a mechanical transmission with a position sensor, autonomous th remote configuration and management. This device is the closest technical solution to the claimed and is taken as a prototype.

A disadvantage of the known controller is that the control functions and settings of the mechanism controller are carried out by signals from a remote device or from a stand-alone remote control, which reduces the efficiency of control and obtaining information about the state of the actuator directly at the installation site and narrows the range of operations of operational personnel.

The objective of the proposed utility model is to expand the functions of operational management and settings of the mechanism controller.

The technical result of the utility model is achieved by the fact that in the controller for controlling the electric actuator, located in the actuator housing under the cover and containing electronic components, including a digital display unit of the controller connected to the output of the central processor unit and made in the form of single LED indicators and a mechanical pointer positions for the review of which a window is made on the cover of the actuator, an autonomous control and adjustment panel I, introduced controls built into the cover of the actuator and associated with the input of the central processor unit, a digital indicator connected to the central processor unit via a digital serial interface. The controls are made of four keys "►"(" "- open)," ◄ "(" "- close)" ▼ "(" STOP ") and" ▲ "(" RESET "). The digital indicator is made of four-digit seven-segment.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a structural embodiment of the controller under the cover of the actuator (in the context), and in FIG. 2 is a front view.

The controller for controlling the electric actuator contains components, including a non-contact position sensor 1 of the output shaft of the actuator 2 made on the Hall effect, a torque sensor on the output shaft of the actuator 2, a central processor unit (BCP) associated with all components of the controller (in Fig. 1 not shown), a block of a digital indicator 3 of the controller and a mechanical position indicator 4, connected through a mechanical transmission with a position sensor 1, autonomous bullets settings and controls with a display and controls, providing information exchange with the BCP via an infrared communication channel for setting up and controlling the controller remotely via an infrared communication channel 5 transceiver located in the digital indicator unit 3. Structurally, the controller for controlling the electric actuator is located under the cover 6 of the actuator 2 in place of the standard sensor unit and corresponds to its installation and overall parameters. All the blocks and nodes of the controller are located on the carrier panel 7, which is also a cooling radiator for the elements. On the cover 6 of the actuator there is a window 8 for viewing the block of the digital indicator 3, the mechanical position indicator 4 and the controls of the four keys 9 "►"(" "- open)," ◄ "(" "- close)," ▼ "(" STOP ") and" ▲ "(" RESET "). The digital indicator block contains six individual LED status indicators 10 (" AVAR "," MOM "," PLACE "," DIST ", “OPEN”, “CLOSE”), a four-digit seven-segment digital indicator 11 and an infrared communication channel transceiver 5. The digital indicator displays, for example, the following information:

- values of the position of the output organ of the mechanism;

- the value of the moment at the output organ of the mechanism;

- settings for the mechanism and controller;

- codes of occurring malfunctions;

The controller’s operation is based on the method of controlling the mechanism’s electric motor by tracking the angular position of the mechanism shaft using a magnetically sensitive sensor mechanically connected to the output shaft of the mechanism and the torque on the output shaft of the mechanism monitored by the torque sensor. The BCP receives control signals for the actuator, for example, “open”, from an external control device, decrypting this signal. The BCP issues a command, for example, “open”, to turn on the actuator electric motor, and at the same time receives digital data from the position sensor 1 about the angular position of the actuator output shaft mechanism, digital data from the torque sensor about the moment on the output shaft of the actuator, that is, it receives information about the parameters of the actuator in real the moment in time, analyzes them and issues such a command to execute a signal from an external control device. At the same time, the BCP performs a functional check, both of the electric motor and the actuator as a whole, to control the electric motor of the actuator, or to disable it for protective purposes. Information about the parameters of the actuator executed by the BCP command is displayed on the digital indicator unit 3, and also transmitted to an external control device. Moreover, the digital indicator unit is combined with a mechanical position indicator connected through a mechanical transmission with a position sensor 2, which allows you to visually control the angular position of the output shaft of the actuator in the absence of electrical power.

The controller can autonomously perform more complex types of control of the movement of the actuator, for example, start-stop motion, positioning, emergency control via an external separate digital or digital signal of the information network. The controller independently stops the actuator when reaching the end positions, or the specified value of the moment when closing and / or opening the valve. The controller settings can be set using the stand-alone settings and control panel with a wireless interface, control keys 9 and the digital indicator unit 3 together, or the information network and are stored in non-volatile memory. Moreover, the wireless interface and keyboard allows you to configure the parameters of the controller without removing the cover of the actuator, that is, without violating the integrity of the actuator. The controller can be controlled from an external control device by discrete signals, analog signals or a network information signal, as well as from a stand-alone control and setup panel and control keyboard 9 with control on the digital indicator unit 3.

Thanks to the introduction to the proposed controller for controlling the electric actuator of the controls integrated in the cover of the actuator and a four-digit seven-segment digital indicator as part of the digital display unit, the functions for the operational management of the mechanism controller and its settings directly at the installation site are provided by setting controller settings control keyboard and display them with a digital indicator, and control From the control keys with control on the digital indicator block.

The inventive controller is planned to be used to control the shut-off and regulating body of pipe fittings in serial actuators, which allows us to conclude that it meets the criterion of "industrial applicability" for a utility model.
