The aim of this project is to become a central control unit (CCU) to interface with all the UO Imaging (and more) devices. The idea is that the cameras, Pan and Tilt mechanisms, AutoFocussing systems and so on should be controllable from a remote location via a simple CLI tool (with auto-correct feature).
The code for this project is located in my Github repo thoughtfully named – UOController
The following diagram should make the idea more clear:
What I want is that the cameras / equipments marked as
should be controllable via this CLI from either Admin’s workstation or from
Admin’s any trusted device (over VPN).
Since I have written most of the other camera’s driving modules in C/ C++, I am using
rabbitmq-c, a C library for rabbitmq to serve the RPC calls initiated by this CLI.
More information on this setup can be found in the
This module requires rabbitmq since it uses that as a broker. To install rabbitmq, follow these steps:
echo "Downloading erlang" wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb echo "Installing erlang-solutions" sudo dpkg -i erlang-solutions_1.0_all.deb echo "Updating package manager" sudo apt-get update echo "Installing erlang and erlang-nox" sudo apt-get install erlang erlang-nox echo "Adding rabbitmq to sources.list" echo 'deb http://www.rabbitmq.com/debian/ testing main' | sudo tee /etc/apt/sources.list.d/rabbitmq.list wget -O- https://www.rabbitmq.com/rabbitmq-release-signing-key.asc | sudo apt-key add - echo "Updating package manager again" sudo apt-get update sudo apt-get install rabbitmq-server echo "Adding Rabbitmq management web plugin and setting up default admin:admin user" sudo rabbitmqctl add_user admin admin sudo rabbitmqctl set_user_tags admin administrator sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*” sudo rabbitmq-plugins enable rabbitmq_management echo "Starting rabbitmq server" sudo systemctl enable rabbitmq-server sudo systemctl start rabbitmq-server
maybe I should just write an Ansible playbook for all this…
