CageEye technical infrastructure requirements

In short

  1. Stable power on the cage and barge

  2. Stable internet

  3. One of these compatible feeding systems

Detailed requirements

These requirements define the optimal environment for CageEye systems. If any of the requirements are not met the CageEye service will be impacted as described in each point.

Cage type:
Hvalpsund HD500NG

Conflict between the top bracket fixture and the handrail post.

Use stainless ratchet straps or rope to tie the top part of the bracket to the pole.

Solution / Løsning

Aeration devices that makes airbubbles inside the cage. Sold under names like(Midt-Norsk ring, Turbolift etc)

The echosounder picks up the bubbles and it creates a noisy image of the fish.

Echosounders are not compatible with aeration devices.

Aside from these components, the equipment is compatible with any other component that is not directly interfering with it. It is compatible with predator nets.

1.2 Cage requirements

  • Minimum 15m deep nets, which gives a 13m sensor head distance.

1.2.1 Coverage for different cage sizes:

~30%

Square 25x25m
20m to deepest point. 15m distance between sensor heads.

~50%

Performance is mainly affected by how well the sensors cover the feeding zone.

1.5 Operational feeding system with integration.

CageEye is compatible with these feeding systems. The blowers, dosing, changers, piping, feed spreaders need to be in working condition.

What happens if the requirement is not met:

You will not get feeding data and you might not be able to feed.

2 Power Requirements

2.1 Power at barge

The CageEye system requires 2kW @ 230V 50hz at the barge.

The system complies with the international EMC standards: IEC/EN 60950-1, IEC/EN 61000-3-3, IEC/EN 61000-6-1 and IEC/EN 61000-6-3.

In case of power source problems such as noise, spikes, brownouts and blackouts, an Online UPS system needs to be installed to accommodate continuous power stability and availability.

What happens if the requirement is not met:

Service stops as soon as the power to the server and antenna is broken. This is mitigated by using a UPS(battery).

2.2 Power at cage

Estimated continuous power requirements for all sensor devices in cage: 60 W
Estimated maximum power consumption in the future 500 W

The CageEye system requires 60 W @ 230V 50hz outlet at the cage. The power supply must have a C16A or a D16A circuit breaker.

What happens if the requirement is not met:

Service stops as soon as the power is interrupted. This is mitigated by using a UPS(battery).

3 Network Requirements

CageEye uses two operating models. Customer managed network, and unmanged network.

3.1 Unmanaged networks

CageEye will install a server on the barge that needs to be on the same network as the feeding systems and the feeding cameras. Remote connections to operations centers can be set up in cooperation with the customers technical staff. CageEye needs to use radios to communicate with the sensors on the cages.

Example of a network setup.

Communication through OpenVPN with CageEye cloud servers; and remote servicing.

Incoming and outgoing

What happens if the requirement is not met:

Dataflow and remote services are interrupted. Data is buffered for some time until recovery.

3.2 Managed networks

For a detailed requirements for operating in customer managed networks see this page. [Private]https://bluegrove.atlassian.net/wiki/spaces/TRB/pages/1305903173/Bluegrove+Cybersecurity+practices#Operating-in-customer-managed-networks. Ask a CageEye representative to get access to this page.

3.3 Optional: Cage to barge network with radio.

If no cage to barge network is available, CageEye can set up a cage to barge network with radio. We typically use the 5GHz band. We use Ubiquity Rocket AC on the barge, and Ubiquity Bullet AC on the cage.

We configure the radio to use given frequencies between 5190-5940 GHz, alternatively the radio can be configured to automatically seek out new frequencies detects interference.
