ACE SmartDome Controller for ObservaDome

1.0 INTRODUCTION

1.1 PURPOSE

The ACE SmartDome is a fault-tolerant controller that allows an ObservaDome

Laboratories, Inc, product to be controlled locally, remotely, and robotically.

It works with any ASCOM compliant software such as DC3 Dream’s ACP or TheSkyX.

For professional clients wishing to integrate a dome controller directly into their software

there is a comprehensive command library. Communication with the ACE SmartDome is

through TCP/IP. An option to use a serial communications port is available.

This document describes how to operate the ACE SmartDome™and how to install the

SmartDome™software.

1.2 SAFETY

 WARNING

▪The ACE SmartDome™ has automation features that may close the

dome without warning.

▪In order to prevent unexpected dome motion if you are working on the

dome press the ESTOP buttons on the boxes.

▪If working on the upper part of the dome consider isolating the

conductor bar power if appropriate to the task at hand.

▪Read this manual and understand how the system works before doing

any work on the dome.

1.3 DEFINITIONS

SmartDome™

The term “SmartDome” refers to the equipment which is used to control an astronomical

observatory so as to open and close the dome and align the dome with the telescope. The

name is also applied to the high-level software that is used for testing the system.

ACE SmartDome Controller for ObservaDome

1.5 SYSTEM HARDWARE DESCRIPTION

The system can be divided into those components that are static and those that move with

the dome.

The static components are:

▪Main box with push buttons and a LCD screen

▪Azimuth control box

▪Azimuth motors

▪Encoder

▪Home sensor

▪Conductor bar power switch

▪External cloud or other sensor(s) mounted outside the dome building

FIGURE 1-1 SMARTDOME STATIC COMPONENTS

ACE SmartDome Controller for ObservaDome

The rotating components are:

▪Top box with push buttons

▪Conductor bars

▪Rain snow sensor mounted on the outside of the dome

▪Limit switches

▪Home sensor trigger arm

FIGURE 1-2 SMART DOME ROTATING COMPONENTS

1.5.1 Main Control Box

This is located on the fixed wall of the observatory, usually vertically below one of the

azimuth motors. It contains a Linux-based computer board with an SD card and a

proprietary interface board that connects all the hardware to the computer.

There are five push buttons on the front panel. The EMERGENCY STOP button locks

into place when it is pressed. To release, twist the button and it pops back out. There is an

extra contact on the emergency stop button to allow an independent signal to be sent to the

telescope controller. The OPEN/CLOSE buttons are for the main shutter door. There is a

small delay (2 seconds) when reversing direction to prevent damage to the system.

ACE SmartDome Controller for ObservaDome

Unlike some systems there is no “Remote / Local” switch to go between computer and

manual control which could be left in the wrong position requiring a trip back to the

observatory. The system can handle both the computer and manual operation

simultaneously.

1.5.1.1 LCD Screen

The LCD screen is useful during engineering setup. It gives status of the dome such as

azimuth position, the status of the doors, weather, and system status.

1.5.2 Azimuth Control Box

This is located on the fixed wall of the observatory, usually just above the main control

box. It contains a programmable variable frequency drive (VFD). This permits slow

acceleration and rapid deceleration of the azimuth motor(s).

1.5.3 Azimuth Motors

The system has been equipped with 3-phase azimuth motors that are controlled by the

variable frequency drive.

The speed of the dome is determined by two factors:

▪The speed of the motor, as programmed by the VFD

▪The gear ratio of the box that the motor is attached to.

The ObservaDome is capable of high speed azimuth slewing, up to 15 degrees per second.

1.5.4 Azimuth Encoding

The encoder is attached to the output shaft of the gearbox. It is electrically isolated from

the dome. The encoder produces 500 counts per revolution of the gearbox output shaft.

Azimuth is defined as north being zero and increasing to 90° at east.

1.5.5 Home Sensor

The incremental optical shaft encoder is automatically reset each time it passes the home

position. The home position is usually placed somewhere near south (for northern

hemisphere observatories) as this is likely to be a position that is frequently passed.
