Home Projects Drone Inspection of Solar Farms

The Challenge

Government incentives and lower cost solar cells have seen solar generation rapidly expand across the UK, and with solar energy now contributing significantly to the UK national grid in peak season.

Consequently, solar farms are big business and hence maximising their efficiency is critical for the operators.

Our client, Above Surveying, approached Plextek to enhance their post survey workflow which was a labour-intensive activity and bottleneck for highly trained analysts. Their system uses airborne drones as a scalable solution to capture precise thermographic and video diagnostic data of the solar farms. Our challenge was to consider techniques to translate the data into a format that machine-learning tools could process, and with the requirement to remove solar glint, other artefacts, and then rationalise the images with ground plans.

The Approach​

Plextek provided consultancy recommending the most applicable image processing and machine-learning workflows to allow automated data analysis. Plextek worked closely with Above Surveying technical teams to assess feasibility of different approaches, settling on a recommendation that could be easily implemented within their existing processes and workflow.

The Outcome

Plextek’s input enabled Above Surveying to automate their analysis and remove a bottleneck in an expanding the business. Above Surveying has now checked over 8.5 million solar panels, identifying more than 200,000 defects, which ultimately allow their solar farm customers to optimise efficiency and revenue.

mmWave Imaging Radar

Camera systems are in widespread use as sensors that provide information about the surrounding environment. But this can struggle with image interpretation in complex scenarios. In contrast, mmWave radar technology offers a more straightforward view of the geometry and motion of objects, making it valuable for applications like autonomous vehicles, where radar aids in mapping surroundings and detecting obstacles. Radar’s ability to provide direct 3D location data and motion detection through Doppler effects is advantageous, though traditionally expensive and bulky. Advances in SiGe device integration are producing more compact and cost-effective radar solutions. Plextek aims to develop mm-wave radar prototypes that balance cost, size, weight, power, and real-time data processing for diverse applications, including autonomous vehicles, human-computer interfaces, transport systems, and building security.

On the Radiation Resistance of Folded Antennas

This technical paper highlights the ambiguity in the antenna technical literature regarding the radiation resistance of folded antennas, such as the half-wave folded dipole (or quarter-wave folded monopole), electrically small self-resonant folded antennas and multiple-tuned antennas. The feed-point impedance of a folded antenna is increased over that of a single-element antenna but does this increase equate to an increase in the antenna’s radiation resistance or does the radiation resistance remain effectively the same and the increase in feed-point impedance is due to transformer action? Through theoretical analysis and numerical simulations, this study shows that the radiation resistance of a folded antenna is effectively the same as its single-element counterpart. This technical paper serves as an important point of clarification in the field of folded antennas. It also showcases Plextek's expertise in antenna theory and technologies. Practitioners in the antenna design field will find valuable information in this paper, contributing to a deeper understanding of folded antennas.

Frequency-Scanning Substrate-Integrated-Waveguide Meanderline Antenna for Radar Applications at 60GHz

This paper describes the design and characterization of a frequency-scanning meanderline antenna for operation at 60 GHz. The design incorporates SIW techniques and slot radiating elements. The amplitude profile across the antenna aperture has been weighted to reduce sidelobe levels, which makes the design attractive for radar applications. Measured performance agrees with simulations, and the achieved beam profile and sidelobe levels are better than previously documented frequency-scanning designs at V and W bands.

A Ku-Band, Low Sidelobe Waveguide Array Employing Radiating T Junctions

The design of a 16-element waveguide array employing radiating T-junctions that operates in the Ku band is described. Amplitude weighting results in low elevation sidelobe levels, while impedance matching provides a satisfactory VSWR, that are both achieved over a wide bandwidth (15.7-17.2 GHz). Simulation and measurement results, that agree very well, are presented. The design forms part of a 16 x 40 element waveguide array that achieves high gain and narrow beamwidths for use in an electronic-scanning radar system.

Sensing Auditory Evoked Potentials with Non-Invasive Electrodes and Low-Cost Headphones

This paper presents a sensor for measuring auditory brainstem responses to help diagnose hearing problems away from specialist clinical settings using non-invasive electrodes and commercially available headphones. The challenge of reliably measuring low level electronic signals in the presence of significant noise is addressed via a precision analog processing circuit which includes a novel impedance measurement approach to verify good electrode contact. Results are presented showing that the new sensor was able to reliably sense auditory brainstem responses using noninvasive electrodes, even at lower stimuli levels.

Long Range Retro-Reflector

Passive retro-reflectors that modulate a scattered RF signal but do not transmit in their own right are well known. They are widely used in RFID tags, and keyless entry systems with a number of standardised solutions defined within the industry. The main advantage of these systems is that the mobile unit (the tag) can either avoid completely the use of a battery by powering itself from the incident RF ‘interrogating’ signal or only require a very small battery with a long life. This enables a ‘disposable’ tag to be engineered at very low cost, size and weight. However, there are many potential applications that require a somewhat longer transmission range than can sensibly be achieved with this method. The conventional paradigm requires a higher power ‘interrogating’ signal in order to increase range and there are obvious limits to how far this can be taken. The combination of regulatory restrictions and the steep range vs power slope that results from the fundamental mode of operation generally restrict the range to a few metres at most. Plextek have been taking a fresh look at the possible ways of circumventing this obstacle to produce a long range device that is nevertheless RF passive (does not transmit but only scatters). This paper describes in outline some ideas in this space, some initial experiments that have been done and some potential applications of the techniques.

An Optical Room Occupancy Sensor

An automated sensor system that determines whether rooms within a building are occupied by a person or people has many applications. These divide broadly into the following classes: Security: Whole-site surveillance from control node, cases where a room should not be occupied, intruder detection and asset tracking. Safety: Identification of lone workers during non-core hours and remote supervision of isolated working environments. Confirmation of building evacuation. Management of high risk processes. Facilities Management: Environmental controls (lighting/heating) to meeting room booking aid. Sensors that seem to solve this problem are plentiful and it is only when they are considered in detail that their deficiencies become apparent. This short paper makes this case and introduces a new type of sensor based on an optical method.
