Description

SCOPE OF THE INVENTION

The present invention relates to a system for the remote monitoring of an autonomous power generating apparatus, and more particularly a system for the monitoring and maintenance of remote lighting and/or security or video installations which may be photovoltaic, wind turbine and/or other direct current source powered.

BACKGROUND OF THE INVENTION

The use of powered lighting installations is becoming more and more prevalent. Such installations have proven highly effective, particularly when used in remote locations where conventional electrical grid access is not commercially feasible.

Various third parties, such as United States Patent Publication No. US 2010/0029268 A1 to Myer, published 4 Feb. 2010, have disclosed systems for monitoring and controlling solar powered light installations remotely. In the system developed by Myer, a number of solar powered light poles are provided to wirelessly transmit and receive from a remote controller, information relating to grid usage and/or power outages. The remote controller may be used to activate LED lights on the poles and/or if connected to the grid, supply photovoltaic generated power back into the grid in the case of high load applications.

The applicant has appreciated, however, that by their nature, the installation of remotely located solar and/or wind powered lighting and other autonomously powered installations presents a unique problem from the point of view of servicing. With conventional solar installation monitoring systems, when a fault or low performance signal is transmitted from a particular solar light pole, the remote location of the solar light pole prevents, on a cost efficiency basis, service technicians from undertaking an initial on-site visit to diagnose the problem. As a result, the manufacturer/maintenance organization will in the first instance, forward replacement parts or components to rectify the perceived “defect”. As a result, light pole repairs are often undertaken which are either inefficient or unnecessary where, for example, low power output or insufficient battery charge results from environmental conditions, such as prolonged periods of cloud cover, or dirt or other organic growth covering photovoltaic cells or other electricity generating components.

SUMMARY OF THE INVENTION

The present invention therefore provides for a system of monitoring and/or maintaining remotely located autonomously powered devices. Such devices may include, without restriction, photovoltaic and/or wind powered lights, security systems (video cameras, motion detectors, and/or infra-red lights), parking meters, charging stations, bike rental platforms and/or cellular or radio transmitters, as well as other wind turbine or power generation installations.

In one mode of operation, the system is operable to receive data signals from a number of the devices, and on detecting a default condition of a particular device, provide a comparison with other similar devices in the same geographic region to assess whether the defect is in fact environmental to devices in a given geographic region, or rather particular to the specific device itself. In another mode of operation, the system is operable to receive data signals from a number of the devices, and on detecting a default condition of a particular device, provide a comparison with other devices of similar technical and situational configuration (across multiple geographies) to assess whether the defect is in fact environmental to components of devices of a given configuration, or rather particular to the specific device itself. In a most preferred mode, data is received and analyzed by a suitable controller such as a processor, and most preferably wirelessly by a central processor which is used in the monitoring and control of a number of separate geographically remote installation sites.

Another mode of the invention provides a system for the monitoring and/or control of an array of autonomous self-powered devices, such as solar and/or wind powered lights, security cameras, display boards, environmental sensors, telecommunications and the like, and which are typically powered at least in part, by a rechargeable battery or fuel cell (hereinafter the battery). The system is operable to provide for the monitoring and/or control of individual device operating parameters on an individual basis, on a regional basis, or through other groupings such as technical parameters (e.g. by versions of technology) over a preset period of time for day to day operational control, prescheduled maintenance, preventive maintenance, emergency maintenance and life cycle maximization. Although not essential, more preferably, the system includes memory for storing such operating parameters and data. The system may in one embodiment, thus, provide for self-learning algorithms from an analysis of past data, extrapolate future device operating performance expectations and/or parameters, and output modified control commands to the devices in response to the past performance and/or self-learning algorithms remotely.

In yet another possible mode of control data to the individual solar lights or other load sources of each installation site is weighted or adjusted having regard to either short term projected weather forecasts or events and/or projected seasonal average or long term forecasts.

In one possible embodiment, environmental conditions such as earlier weather events (sun position, temperature, UV intensity, fog, snow, etc.) are logged and compared against past site power generation and/or load performance. The generation and/or load data is then stored as part of a predictive model to anticipate similar generation and/or load performance values for like weather events moving forward. In a most preferred embodiment, the current operational performance of a site installation is weighted by having regard to past performance during such events and/or controlled predictively having regard to future/current events.

By way of non-limiting example, where a short term forecast for an installation site at a particular geographic region predicts an upcoming period of inclement weather or rain and cloud cover with high wind velocities, and which for example is characterized as likely to result in increased power generation by the installation site wind turbines, control signals may be sent to the installation site to operation power load with increased output intensity and/or time of operation to reflect the reduced visibility during times of increased power output from turbine generators.

Similarly where short term forecast data is provided which is indicative of a predicted time period of both lower wind velocity and solar energy generation, as for example on the occurrence of fog and/or extended periods of rain in the absence of significant winds, a control signal may be output to the installation to reduce the operation times and/or intensity of the loads, as for example by reducing the lumen output of solar lights and/or their activation times to reflect any reduced re-charging.

In addition to short term environmental factors, the output control to the load devices at each installation site may also be regulated by events such as seasonal environmental and/or weather trend factors. By way of example, in northern latitude regions in the spring and fall which are typically characterized by periods of sustained increased winds, the controller may be used to provide control the output loads to increase power output, provide overall brighter lighting and/or longer periods of operation either before complete sunset and/or after complete sunrise, and which would reflect the increased battery recharge capacity attributable to increased wind turbine efficiencies. Similarly during seasonal periods of reduced sunlight exposure and/or the increased tangential impact of solar relative to the solar panel, the controller may be used to provide signals to control the system to provide for the intermittent, selective and/or shortened operation of individual load devices, reduce the overall load intensity of the installation site and/or output times to reflect slower battery recharge capacity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference may be had to FIG. 1 which illustrates schematically a monitoring, control and maintenance system 10 for remotely located autonomously powered lighting, security/video, monitoring (weather, environmental (including pollution), industrial (flow, sewage, water) or telecommunications (cellular, WiFi, etc.) installation systems. In the embodiment shown, the system 10 includes an autonomously powered light pole array 12, a central processing unit (CPU) 14 for receiving operational data signals from and providing central signals to the array 12 and a data storage repository 16. The light pole array 12, central processing unit 14 and data storage repository 16 are most preferably provided in wireless electronic communication by a suitable cellular, Zigbee or WiFi communications network 18.

The light pole array 12 preferably consists of a number of autonomously powered light poles 20 which are installed for operations at a geographic location remote from the CPU 14. The light poles 20 forming each array 12 may optionally include at least one telecommunications aggregator pole 20′, as well as a number of conventional poles 20. In particular, by reason of their autonomous power source, the light poles 20 are particularly suitable for installation in geographically remote regions which, for example, may lack conventional power infrastructure such as electrical or telephone transmission lines, or even seasonal roads. In this regard, the light pole array 12 may be situated several hundred or even thousands of kilometers from the CPU 14, not only in developed areas, but also along borders or in other geographically inaccessible areas.

FIG. 2 shows best the basic design of each light pole 20 using the system 10. The poles 20 include an aluminum column 22 which extends vertically from a hollow base 24. The column 22 is used to mount above the ground a pair of LED lights 26a, 26b as respective electric loads, as well as a pair of solar or photovoltaic panels 28a, 28b and a top mounted wind turbine generator 30. A fuel cell or battery 38 is housed within the interior of the base. As will be described, the fuel cell 38 both receives and stores charging electric current generated by the photovoltaic panels 28a, 28b and wind generator 30, and supplies a discharge electric current to the LED lights 26a,26b in response to control signals received from a pole communications and monitoring controller 42.

The photovoltaic panels 28a,28b and wind turbine generator 30 are each electronically coupled to respective voltage/current sensors 32a,32b,34. The voltage/current sensors 32a,32b,34 are operable to provide signals correlated to the voltage and electric current generated by the panels 28a, 28b and wind turbine 30 in real time. In addition to the current sensors 32a,32b,34, each pole 20 includes additional sensors for monitoring environmental and/or pole operating parameters. Optionally, a photovoltaic sensor 44 is provided to provide signals respecting ambient and/or sun light at each pole location.

Similarly a battery temperature sensor 40 within the interior of the column adjacent to the fuel cell 38 provides data relating to the battery temperature and/or ambient air temperature. In addition, optionally wind sensors may be provided as either a separate anemometer, or more preferably as part of the turbine generator 30 itself.

FIG. 3 shows best schematically the pole communications and monitoring controller 42 as being operable to receive data signals from the sensors 32a,32b,34,44,46 and provide control signals to regulate the supply of charging current from power generation produced by the photovoltaic panels 28a,28b and wind generator 30 to the fuel cell 38, as well as battery status and the discharge supply current therefrom to the LED lights 26a,26b. Although not essential, most preferably, the communications and monitoring controller 42 further includes signal transmission and reception capability allowing the communication and/or transmission data and programming respecting the operating parameters of the pole 20, fuel cell 38 and/or load conditions between adjacent poles 20 within the light pole array 12 by either Ethernet or serial USB connections.

The telecommunications aggregator pole 20′ is essentially identical to the other poles 20, with the exception in that its communications and monitoring controller 42, which includes a Zigbee, cell, Ethernet, or WIFI transmitter 50 (FIG. 3) configured to upload data and/or receive control programming from the CPU 14 for the entire array 12 via the cellular communications network 18. In one most preferred embodiment, within the light pole array 12, each pole 20 is provided with a Zigbee, cell, or Ethernet transmitter to communicate data to the data storage repository 16 directly without going through a telecommunications aggregator pole 20′. In a more economical construction, however, a single telecommunications aggregator light pole 20′ is provided with the Zigbee or cell transmission capability. The light pole 20′ is adapted to receive and retransmit data from the remaining light poles 20 within the array 12 to the cellular communications network.

In a further optional embodiment, the communications and monitor controller 42 may also electronically communicate with either a stand-alone weather station situated at the remote location, and/or motion detector or other environmental sensors.

The operation of the system 10 is shown best with reference to FIG. 4. In particular, in a most preferred mode of operation, data from the individual light poles 20 is uploaded via the cellular communications network 18 to a cloud-based processing and data storage repository 16. Although not essential, the use of a central data processing and data storage repository 16 permits multiple individual users accessing their own CPU 14 to monitor, assess and affect maintenance requirements on a number of different geographically remote light pole arrays 12. In particular, the communications and monitoring controller 42 of the poles 20 in each array 12 monitors inputs from the various sensors 32a,32b,34,44,46. This permits the system 10 to collect and monitor data respecting the voltage and current which is generated by each light pole 20, turbine 30 and photovoltaic panels 28a,28b, and record data as external factors such as temperature, wind and/or sunlight conditions at each remote region received from the photovoltaic and environmental sensors 32,32b,34,44,46.

The system 10 provides the ability to intelligently change the energy use of the individual light pole 20 loads under certain conditions to achieve lower maintenance, better performance, higher reliability and maximize the life cycle of the system.

By way of example, if a weather forecast for the next 10 days may be for cloudy weather, the system 10 may determine not enough sun will be received. The CPU 14 proactively manages energy use of the light or other system load to manage through this ‘brown-out’ time period.

Similarly the micro wind environment of specific locations or the sun profiles of a specific location of the pole 20 dictates lower energy generation. It is possible to change the energy use to manage it so that the system 10 delivers light at reduced hours of operations or dimmed levels to ensure the system continues to perform.

The system 10 further allows for the analysis of specific device or pole 20 performance against all of the other poles 20 (‘calibration in the cloud’). Where on a select pole 20 the solar panels 28 do not operate according to the specifications or according to the expected performance relative to how the other systems are performing, or the battery does not meet specified levels, the system can change the energy use to make the pole 20 perform and meet the life cycle targets.

The life cycle of the poles 20 may evolve and change due to battery discharges and other stresses. The system 10 allows for recording of the history and performance of the system and to evolve the energy use/charging to maximize the life of the battery. Customization of the battery charging algorithms based upon environment, application and age of the system of the specific unit may also be achieved.

Most preferably, the communications and monitoring controller 42 includes an internal processor which may pre-filter the collected data to ensure that the individual operating parameters of the light pole 20 are performing within a predetermined acceptable range. Where the sensed data determines that power generation and/or load output falls outside the pre-selected ranges, the communications and monitoring controller 42 may be used to effect power reduction to the loads (i.e. dimming of the LED lamps 26a, 26b) and/or adjust the fuel cell 38 charging time accordingly.

The data received from the light pole sensors 32a, 32b, 34, 44, 46 is transmitted by the communications and monitoring controller 42 by the telecommunications aggregator pole 20′, for each pole in the array 12 via the cellular and/or ZigBee communications network 18 to the data storage repository 16.

Data respecting the light pole power generation and load usage as well as environmental data for each pole 20 is stored in the repository 16 for each pole 20 of each array 12.

By means of the CPU 14, a system administrator can thus monitor power generation for the entire array 12 in aggregate, as well as on an individual light pole 20 basis. Similarly, environmental, wind generation and/or photovoltaic conditions can be aggregated for the entire pole array 12 (or part thereof) and compared against individual data on a selected pole-by-pole basis.

The system 10 thus advantageously allows a user to monitor and control individual light poles 20 having regard to not only the individual pole operating parameters, but also overall environmental conditions.

In one mode, the system 10 is used to monitor and/or control LED light operations 26a, 26b, and if necessary provide maintenance instructions as a result for a selected light pole 20. In particular, in the case of LED lights 26a, 26b, initially LED lamps have a tendency to burn with increased brightness in the first instance, characterized by a reduction in lumen output over time. As such, over the lifespan of a conventional LED bulb, the bulbs may be initially too bright, and subsequently insufficiently bright for the intended site of installation.

In one preferred mode, the CPU 14 is used to transmit control signals 104 to the communications and monitoring controller 42 to operate LED light loads 26a, 26b at reduced power levels for an initial pre-selected period. As the lamps in the LED lights 26a, 26b age, the CPU 14 controls the communications and monitoring controller 42 to increase power to the lights 26 to compensate for any reduction in performance.

In another embodiment, external data from other sources outside of the system 10 may also be loaded into the data storage repository 16 for the purposes of servicing the pole 20. In one instance, where there is an external weather forecast of severe weather with high winds, the CPU 14 may by way of communications and monitoring controller 42 modify the power draw from the wind turbine 30 and configure the turbine 30 to be best able to withstand a high wind event that could cause a failure to the system 10.

With the present system 10, the communications and monitoring controller 42 will upload to the data storage repository 16 to log historical profiles of battery performance. Depending upon the number and rate of battery charging and discharging over periods of time, the CPU 14 may by way of the communications and monitoring controller 42 modify the charging and discharging rate to and from the battery 38 with a view to extending battery life performance. In addition, depending upon environmental conditions for the pole array 12 as determined by the photovoltaic and environmental sensors 36, 46, where, for example, the geographic region where the light pole array 12 is subject to prolonged periods of either cloudiness and/or becalmed winds so as to result in a reduction of charging power to the battery, the CPU 14 may be used to signal the communications and monitoring controllers 42 of each light pole 20 within the light pole array 12 to either dim the output light intensity of the LED lights 26a, 26b and/or their operation time to compensate for regional environmental anomalies.

The present system 10 therefore allows for the remote troubleshooting and performance testing of the solar panels 28a, 28b, as well as the wind turbine 30 for each individual pole 20, by a remote web based user or smart device 108. Most preferably, the CPU 14 is operable to effect control signals to the communications and monitoring controller 42 to provide remote open voltage tests and remote short circuit tests on solar panels 28a, 28b. Similar tests for other systems components are also enable by CPU 14. By assessing the operating data stored in the data storage repository 16 for a number of light poles 20 and/or light pole arrays 12, it is therefore possible to compare individual light pole 20 performance across an aggregate number of poles to filter environmental versus hardware defects. The analysis of the performance of individual light poles 20 as compared to the aggregate of the light pole array 12 advantageously may eliminate and/or reduce needless service calls, particularly in case of the light pole arrays 12 which are installed at highly remote or physically inaccessible locations. By way of example, typically power line tree removal is currently undertaken on a ten year cycle, irrespective of whether or not an actual determination has been made whether it is needed. The present system therefore allows a system administrator to assess whether or not a number of light poles 20 in a particular array 12 are performing at a substandard level, triggering a call for intelligent maintenance when for example plant growth is adversely effecting the solar panel 28a, 28b and/or wind turbine 30 operation. It also allows for a system administrator to eliminate a scheduled maintenance operation in the event that a light pole 20 is operating according to design objectives.

Installation Diagnosis

In a first exemplary mode of operation, the system 10 is used to identify installation defects where for example solar panels are installed in an incorrect orientation or with over shading structures. By comparing individual solar panel degradation within a configuration of multiple panels, and optionally comparing the performance over a longer period of time to take into consideration the seasonal change in power, the system 10 can identify upcoming potential service issues. In another situation, where a visual inspection of pole 20 may indicate potential shading or other issues, the system may identify that such degradation does not affect the overall performance of pole 20 and therefore, no servicing action is required.

By tracking changing power output levels for each solar panel 28a, 28b over the calendar year and the change in sun position, it is possible to identify incorrectly positioned solar panels 28a, 28b and obstructions arising from seasonal changes by comparing the average solar panel output for the geographic population of the solar panel array. It is also possible to identify individual solar panels 28a, 28b that provide increasing or decreasing outputs on a seasonal basis. Seasonal change in solar output provides an indication that the changing azimuth of the sun causes the solar panels 28a, 28b to be mis- positioned where overlying obstructions may provide shadows.

In the event performance drops below predetermined thresholds, the CPU 14 is used to output a maintenance control signal to either a third party maintenance technician or alternately power down pole 20 or alter load power to preserve battery integrity.

Component Failure

In a second exemplary mode of operation, the system 10 is used to identify component defect or failure for a selected pole 20 within the array 12. The cloud 16 is used to provide a pooled performance output of the array 12, taking into consideration internal and external data point factors, on both a calendar and anticipated product lifespan basis. The CPU 14 is used to identify any individual poles 20 which are providing performance output parameters, which fall below a preselected threshold or warranty thresholds from the average performance for the array 12. In a simplified analysis, individual poles 20, which are operating below the predetermined threshold of the array 12, are identified and tagged for possible maintenance or repair. More preferably, individual pole 20 performance as well as array 12 performance is further assessed with respect to the anticipated degradation rates expected by manufacturer. In this regard, the system 10 advantageously may be used to identify arrays 12 where environmental factors have affected array 12.

Corresponding assessments may be made with respect to wind turbine 30 performance. In measuring turbine performance of an individual pole 20, the CPU 14 may be used to assess data from the cloud 16 to provide an indication of anemometer measured wind speed within the geographic region of the array 12 or alternatively a portion of the geographic region. The measured wind speed may be compared against pre-projected energy output of the mass performance of the turbines 30 to identify any individual turbines 30, which have fallen below acceptable threshold levels. In an alternate embodiment, power output data for a selected number of pole turbines 30 within a portion of the array 12 is used as a reference. Individual turbine 30 output within the sample population is then assessed for any selected poles 20 which are performing below outside threshold tolerance levels. Assessment may be made periodically and/or averaged over various time periods based upon certain factors. In an alternate embodiment, testing may be prescheduled having regard to anticipated optimum wind or environmental conditions, selected to provide the desired reference output.

In a further exemplary embodiment, battery temperature, depth of discharge and frequency of deep discharge for each battery 38 within the array 12 is recorded and stored within the cloud data repository 16, over time. The depth and frequency discharge data for individual batteries 38 may thus be compared against averages for the population and optionally adjusted for manufacturer's anticipated life span degradation to identify instances where battery 38 performance falls below acceptable performance levels. In this manner, the system 10 may be used to highlight and isolate individual poles where individual batteries may be susceptible to individual failure.

Component Life cycle Degradation

In a further exemplary embodiment, the system 10 is operated to monitor and predict ongoing maintenance needs for the array 12 as a whole. The system 12 could be used to assess the performance of the entire array 12 against a series of further geographically remote arrays 12; as well system 10 may be used to assess an array 12 of poles 20 against the manufacturer's projected performance having regard to component age.

Scheduled Maintenance

In a further exemplary embodiment, the system 10 may be used to identify and or predict scheduled maintenance needs for individual light pole components such as solar panels 28a, 28b, batteries 38, LED lamps 26a, 26b or other load or energy generation devices.

The CPU 14 may be used to access historical data from the repository 16 to monitor the discharge supply current for each pole 20 in the individual array 12 and/or alternatively other arrays 12 of similar attributes. On a degradation of the discharge supply current for the selected array 12, CPU 14 analysis may, for example, provide an indication of dirt fouling of the solar panels 28a, 28b or lights such that systems begin to fall under manufacturer's performance projections. Data can be compared with environmental data stored on the repository 16 to provide an assessment whether or not solar panel blockage is a result of cloud or fog conditions or more direct environmental impacts such as dust or snow or alike. In the latter case, the system 10 may be used to provide a signal to remote maintenance personnel signalling that the solar panels 28a, 28b or lamps 26a, 26b may need cleaning or other maintenance. Alternatively, the system 10 can be signalled to modify the operation of the system 10 to reduce the discharge power output level and time ensuring the system 10 continues to perform for a longer period of time before the maintenance can be scheduled and delivered.

By using data stored in the repository 16 for a number of different autonomously powered light installations within similar regions, the system 10 allows for layout and performance calculations to be undertaken using theoretical calculations from tools such as Homer™. In particular, over time the system 10 will gather actual performance data for the light poles 20 within the array 12 and will permit the calculations of variance versus theoretical algorithms allowing future systems to be designed and/or tailored having regard to the actual measured performance data. More preferably, the CPU 14 will allow for the system 10 to self-learn, permitting the modification of theoretical adjustments and/or assumptions, as more and more systems 10 are brought online.

By the use of the systems 10, it is further possible to generate performance curves for the individual wind turbine generators 30. The turbine performance curves can thus permit users to monitor individual turbine power generation for a selected pole 20 as compared to the average for the entire pole array 12, allowing for an individual assessment of performance and/or deterioration.

Similarly, the system may be used to provide maintenance warnings or indications of solar or photovoltaic panel deterioration. In particular, as individual photovoltaic panels 28a, 28b become pitted and damaged, by monitoring the performance of power generated for individual poles 20 versus the entire light pole array 12, or even a regional average of photovoltaic panels for a particular area, it is possible to assess whether maintenance and/or panel replacement may be required where power generation falls below a pre-selected value.

In yet a further exemplary embodiment, the CPU 14 is operable to access third party predictive environmental data including predictive near-term data such as short term weather forecast data for the coming one to three weeks (i.e. cloud coverage, wind speeds, etc.); as well as predictive seasonal data (sunlight, solar intensity, predicted short term and/or average seasonal temperature, average wind speeds, average precipitation, etc.). In response to the predicted environmental data, the CPU 14 is operable to output control signals via the communications and monitoring controller 42, to modify load profiles including one or more of power intensity and/or time of operation of the lights and the charging and/or discharging rates to and from the battery

With the embodiment, load profiles can be configured at the light pole 20 or device, or through the CPU 14. Either way, the load requirements can be determined from an energy requirements perspective in order to determine how much available energy is available on-hand in the event that energy generation is anticipated to be problematic due to upcoming weather conditions.

In one possible mode, the CPU 14 determines that the system 10 has an exemplary storage (i.e. five days' worth) of stored energy to operate, assuming the battery 38 is to provide a load profile without degradation, and may be fully recharged by average wind and/or solar output over that time period. Where the CPU 14 receives weather data predicting significant cloud cover approaching for an extended period, the CPU 14 may anticipate situations where the stored available energy on-hand may decrease, and could potentially run out.

With advance weather predictions available on the Internet, and from third parties, it is possible to predictively forecast when adverse weather conditions are to occur and adjust the operating parameters of the system 10 to extend the amount of energy available, as for example through decreased windows of light operation and/or through dimming of operational light sources.

In a mode of implementation an operating matrix for each system 10 includes a prediction model for each light 42 or load device based upon its installation GPS coordinates, time, and date. The further north or south that a light 42 or device is located will impact the seasonally maximum amount of energy generated under optimum conditions. A base level matrix may thus be utilized by the CPU 14 to determine on which days the system 10 can be expected to fully recharge batteries 38, as well as predict situations where battery charging can be compromised.

The matrix can furthermore be utilized with other diagnostic applications, as for example to determine when the system 10 is not performing as expected. It can also be utilized from a sizing perspective to design new installations to meet the changing light for each individual location, and/or provide diagnosis warning of post installation growth, obstruction, or building that was not present when the system 10 was installed and/or when solar panels 28a,28b need cleaning due to buildup of materials on the surface of the panel (more noticeable in southern climates where solar panels are angled more horizontally in nature).

In one possible monitoring mode, the light poles 20 continuously transmit telemetry data to the CPU 14 on a user-configurable schedule. This information may for example include information about monitor sensor activation, low voltage disconnects, low voltage reconnects, etc. The light pole array data is sued by the CPU 14 for predictive analysis of the normal operating environment for each light pole 20 and/or the array 12. In situations where a motion sensor is included, the CPU 14 could collect data and determine whether the motion sensor activates repeatedly between pre-set period (i.e. the hours of 8 p.m. and 11 p.m. at an office location) which can be used to accurately predict the energy requirements at smaller time intervals.

On an hourly, daily, etc. period, the CPU 14 will update its weather parameter such as predicted wind speeds and/or predicted sunshine intensity, as for example as a weighted valve calculated by one or more of time of year, period of each system 10 based upon third party weather reporting API. The predictive model will only force changes at the light pole 20/device level when the amount of storage fails to meet the anticipated load profile and the battery charging profile required to maintain the load profile. In such a case, the CPU 14 provides a control signal to the light pole array 12 requesting a profile change to extend energy storage. The CPU 14 signals will also include recommended programming changes based on the inventory of the attached energy generation devices (solar panels 28a,28b, wind turbines 30, etc.), as well as available battery or power storage facilities.

In addition, the owner/operator of multiple systems 10 can indicate to the CPU 14 which arrays 12 and/or individual light poles 20 have a higher priority than others (security cameras, for example). This information is used by the CPU to weight the operational performance of the light poles having regard to similar weather and/or seasonal conditions and to control that a selected remote light pole 20 or device changes its operating parameters for energy conservation. In one possible mode, a security camera could be kept online as long as possible whilst other loads in the array 12 such as lighting could be dimmed and/or disabled entirely (weather sensors, etc.).

While FIG. 2 illustrates a preferred light pole 20 which includes as electric loads a pair of LED lights 26a, 26b, the invention is not so limited. Reference may be had to FIG. 5 which illustrates a light pole 20 in accordance with a further embodiment of the invention, in which like reference numerals are used identify like elements.

In FIG. 5, the light pole 20 is provided with a single LED light 26. In addition, as further load sources, the pole 20 is used to mount one or two video sensing cameras 52, one or two Infrared Light Sensors (likely with Photocell) 50, one or two Motion Detectors, and separate wireless router for redundant and/or secure communications. It is to be appreciated that in the embodiment shown, the communications and monitoring controller 42 is used to provide control signals to and receive control signals from the infrared light 50, the motion detector and the security camera 52, as well as receive and transmit to the data storage repository 16 and or directly to the CPU 14 video images there from.

It is believed that incorporating light poles 20 of the type shown in FIG. 5 within the light pole array 12 advantageously may be used to provide off grid security.

FIG. 6 shows schematically the pole communications and monitoring controller 42 as being operable to receive data signals from the sensors 32a, 32b, 34, 44, 46 and provide control signals to regulate the supply of charging current from power generation produced by the photovoltaic panels 28a, 28b and the wind generator 30 to the fuel cell 38, as well as battery status and the discharge supply current therefrom to the video sensing cameras 52, infrared light sensors 57, and motion detectors 54. Although not essential, most preferably, the communications and monitoring controller 42 further includes signal transmission and reception capability allowing the communication and/or transmission of data and programming respecting the operating parameters of the pole 20, fuel cell 38 and/or load conditions between adjacent poles 20 within the pole array 12, as well as information captured by the sensing cameras 52, infrared sensors 57 and motion detectors, by either Ethernet or serial USB connections 55,56.

Although the detailed description describes the system 10 as used in the remote monitoring and control of an array of combination solar and wind powered lampposts, the invention is not so limited. It is to be appreciated that in an alternate embodiment, the system 10 could incorporate a variety of other autonomous solar powered, wind powered, other direct current or alternating current power sources and/or grid-powered devices providing a load. Such devices could include without restriction, electrically powered security cameras, radio or cellular transmitters, parking and/or utility meters, monitoring stations traffic lights, display boards or the like.

In still a further embodiment of the invention, the system could be provided with autonomous electricity generating wind turbines and/or other power generation sources in addition to, or in place of, the photovoltaic powered light poles, without departing from the current invention.

Although the detailed description describes and illustrates various preferred embodiments, it is to be understood that the invention is not limited strictly to the precise constructions, which are disclosed. Modifications and variations will now occur to persons skilled in the art.
