[0004] Field

[0005] Embodiments herein relate to pulse jet cleaning systems for construction equipment filtration systems and methods of operating the same.

[0006] Background

[0007] Construction equipment is often operated in dusty environments with various airborne contaminants. As such, construction equipment is benefited by filtration of various types. For example, engine air filtration is essential for construction equipment as it protects the engine from dust, dirt, debris and other contaminants that can reduce engine performance and lifespan. Engine air filters are designed to capture and remove these particles from the air before they enter the engine's combustion chamber.

[0008] Filters can load as they remove contaminants from fluid they filter. Filter loading can increase filter restriction and decrease efficiency of system operation. As such, some types of filters are often cleaned, such as with pulses of air, to reduce filter loading and keep filter restriction within a proper range.

[0165] Detailed Description

[0166] Construction equipment is often operated in dusty, dirty environments with various airborne contaminants. Filtration systems are used to prevent dust and other airborne contaminants from causing equipment wear and potential damage. Some types of filters are periodically cleaned using pulses of air to reduce filter loading and keep filter restriction within a proper range.

[0167] Embodiments herein relate to pulse jet cleaning systems for construction equipment filtration systems that can enhance operational efficiency and adaptability to varying environmental and operational conditions. Many parameters of air pulse PDSD No. 758.3090WOU1 cleaning can be controlled by systems herein to optimize filter cleaning and filtration performance. In specific, the system incorporates advanced control mechanisms to manage parameters of the pulse cleaning of filter elements, to maximize filtration performance and reduce equipment wear and prevent damage.

[0168] Embodiments described herein provide a range of benefits, including reductions in both operating costs and equipment maintenance risks associated with filtration systems for construction equipment. The implementation of an automated pulse jet cleaning mechanism enables cleaning of filter elements to be performed rapidly and efficiently, often within a matter of seconds and / or via a user-actuated control (e.g., the push of a button), thereby substantially reducing system downtime compared to conventional manual filter maintenance methods. For example, equipment operators frequently manually clean or replace filter elements to maintain filtration efficiency. This process can result in recurrent costs associated with the purchase of replacement elements and labor expenditures due to out-of-service intervals. Such downtime is particularly detrimental in construction and other operational contexts characterized by high equipment utilization rates and timesensitive work cycles.

[0169] Automated pulse cleaning, as disclosed herein, reduces or eliminates the need for regular manual removal and handling of filter elements, thereby lowering labor costs and increasing productive uptime of equipment. The operational cost savings accruing from reduced manual intervention, minimized replacement part requirements, and faster maintenance cycles yield significant economic benefits over the equipment’s service life and contribute to a lower total cost of ownership.

[0170] In addition to cost savings, embodiments disclosed herein mitigate risks associated with filter service events. Manual removal, cleaning, and / or replacement of filter elements introduces multiple opportunities for potential equipment damage and safety hazards. For example, frequent opening of intake systems during manual filter service increases the risk of inadvertently damaging components, introducing leaks, or improperly resealing critical interfaces, all of which could lead to engine damage. Manual or uncontrolled cleaning, such as using compressed air or mechanical impacts (e.g., striking the filter element against a surface), may occur under suboptimal field conditions, such as on uneven terrain or in elevated locations accessed by ladders or vehicle tires, presenting a significant risk of personal injury (e.g., falls or musculoskeletal injury) as well as unintended damage to filter elements (e.g., rupture PDSD No. 758.3090WOU1 or perforation leading to bypass of contaminants). Furthermore, improvised cleaning in the field often occurs without adequate personal protective equipment, exposing operators to airborne particulates, with attendant health risks (e.g., respiratory and ocular hazards).

[0171] By enabling cleaning operations to be performed while a vehicle operator remains within the operator cab, an environment characterized by filtered and conditioned air, the pulse jet cleaning systems described herein significantly reduce operator exposure to harmful contaminants. Automated cleaning further minimizes the frequency with which service access to the filter housing is required, thereby reducing cumulative exposure to service-related risks, both to the equipment and the personnel. As such, the reduction in manual contact and hazardous activities, coupled with the assurance of reliable and reproducible filter cleaning, provides a safer and more efficient equipment operation and maintenance regime.

[0172] An exemplary filtration system herein can include control circuitry, a filter housing, and a pulse cleaning mechanism. The pulse cleaning mechanism, under the control of the control circuitry, periodically cleans a filter element located within the filter housing. Periodic cleaning under control schemes herein can ensure that the filtration system maintains optimal performance by removing accumulated particulates from the filter element, thus preventing clogging.

[0173] The control circuitry can specifically be configured to manage the operation of the pulse cleaning mechanism including setting operational parameter values thereof. These parameters can include, but are not limited to, pressure drop trigger thresholds, cleaning frequency, pattern, peak pressure of pulse waves, duration, energy, and valve operation characteristics.

[0174] In some embodiments, the system can receive and process data regarding the construction equipment's implements, attachments, or headers to allow appropriate adjustment of filtration system cleaning activity / parameters in response thereto. This data, which can be received via wired or wireless signals, RFID tags, or inferred through various techniques, allows the control circuitry to adjust pulse cleaning parameters dynamically and appropriately. For example, certain implements, attachments, or headers may be associated with a characteristic type of contaminant and the system, after detecting such an implement, attachment, or header, can set the cleaning parameters to optimal values for that type of contaminant. PDSD No. 758.3090WOU1

[0175] In some embodiments, the control circuitry can receive data regarding the operational state of the equipment, environmental conditions, and / or proximity to other equipment or specific locations. This data enables the system to adjust cleaning parameters in real-time, optimizing the filtration system's performance across a wide range of conditions and activities. For example, pulsing at a particular frequency or in response to a certain pressure drop threshold may only be optimal when the equipment is in a particular operational state or states. Systems herein can detect or otherwise receive information regarding operational states and change the cleaning parameters so they are optimal.

[0176] The system can be configured to integrate data from various sources, including on-equipment sensors, off-equipment sensors, equipment associated data networks (e.g., CANbus), and user inputs, amongst other sources. The data gathered allows for a comprehensive understanding of conditions under which the filtration system operates including environmental conditions (e.g., airborne dust levels, airborne soot levels, moisture content, etc.) and the operational state of the construction equipment (e.g., engine state, hydraulic system usage, inferred from vehicle weight - indicating load status, etc.). The control circuitry can utilize such data to make appropriate adjustments to pulse cleaning parameters to suit the current conditions, thereby ensuring optimal filtration performance.

[0177] Sometimes circumstances can arise in which pulse cleaning is, at least temporarily, undesirable. In some embodiments, the control circuitry can be equipped to execute cleaning cycles according to a base control scheme (or default or base control scheme), which can be based on and / or responsive to operational requirements and environmental conditions, but then detect and / or respond to various pause events to temporarily suspend pulse cleaning activities. These pause events can be triggered by a multitude of conditions, including but not limited to, the construction equipment's presence in or entry into a specific geospatial area, proximity to buildings, other machines, humans, or beacons, such as below a certain threshold distance, scavenge fan cessation or temperature anomalies, receipt of vehicle fault codes, particularly those related to engine or brake issues, detection of the equipment's hood being open, the equipment cab door being open, detection that the equipment operator is not in the cab, user input, etc. Upon detecting a pause event, the control circuitry can override the base control scheme to pause pulse cleaning, ensuring that cleaning does not occur under conditions that would be undesirable. PDSD No. 758.3090WOU1

[0178] Embodiments of filtration systems herein represent a significant advancement in the field of construction equipment filtration system operation. By intelligently managing the cleaning of filter elements based on a wide array of detectable conditions and inputs, the system offers improved performance, adaptability, and efficiency. This ensures that construction equipment can operate with minimal downtime and reduced maintenance requirements, even in varying and challenging conditions.

[0179] Referring now to FIG. 1, a schematic view is shown of a piece of construction equipment in accordance with various embodiments herein. FIG. 1 presents a schematic view of a piece of construction equipment 102, designed to illustrate the integration and operation of a filtration system 130 in accordance with various embodiments of the present invention. The figure specifically shows the construction equipment 102, airborne contaminants 104, and the filtration system 130, highlighting the filtration system's 130 role in maintaining the equipment's performance and longevity amidst environmental challenges.

[0180] The construction equipment 102 depicted in FIG. 1 can be a self-propelled piece of equipment. By way of example, the equipment can include, but is not limited to, graders, excavators, backhoes, skid steers, and dump trucks, amongst other equipment. In some embodiments, the equipment can be any type of construction equipment including an air filter system with pulse cleaning capabilities. Systems herein can also be used with equipment associated with mining, forestry, and the like. In some embodiments, systems herein can be used with any equipment including a pulse jet type cleaning system. This variety underscores the filtration system's versatility and adaptability to a wide range of equipment.

[0181] Airborne contaminants 104 represent various particulate matter and contaminants that the construction equipment 102 may encounter during operation. Such particulate matter can include dust of all types (silica dust, mineral dust, metal dust, cement dust, organic matter dust, wood dust, and the like), soil particles, fumes, soot, and the like. These contaminants can significantly impact the performance and efficiency of the equipment if not adequately managed. The presence of airborne contaminants 104 emphasizes the need for an effective filtration system to protect the equipment's internal mechanisms and ensure operational efficiency.

[0182] The filtration system 130 of the construction equipment 102 is configured to mitigate the adverse effects of airborne contaminants 104. The air filtration system PDSD No. 758.3090WOU1 targets the removal of particulate matter from the air before it can enter the equipment's systems. In some embodiments, the filtration system 130 can specifically be an engine air filtration system, indicating its crucial role in protecting the engine from contaminants that could impair its function and efficiency. As previously described, the system comprises control circuitry, a filter housing, and a pulse cleaning mechanism, all working in concert to ensure the filter element within the housing is regularly cleaned and maintained for optimal performance.

[0183] FIGS. 2 and 3 illustrate an embodiment of a filtration system 130 with a pulse cleaning mechanism that may be used in one or more embodiments of an air filtration system as described herein. It will be appreciated, however, that the filtration system 130 shown in FIGS. 2 and 3 is merely one type of filtration system that can be used with construction equipment and various other types of filtration systems are also contemplated herein. A filtration system housing 210 may include an inlet 202 and an outlet tube 204. The outlet tube 204 may be operably connected to an engine intake such that the outlet tube 204 and the engine intake are in fluid communication. Air external to the filtration system housing 210 may enter the inlet 202, passing through filter elements contained within the filtration system housing 210, and exiting through the outlet tube 204 to the engine intake. Therefore, air entering the inlet 202 may be filtered (e.g., through the filter elements) and pass to the engine through the engine intake.

[0184] As shown in FIG. 3, the outlet tube 204 may be described as an inner tube 240 that extends into the filtration system housing 210. For example, the inner tube 240 may extend along a longitudinal axis 201 between an inner filter outlet end 242 and an inner engine intake end 244. The inner engine intake end 244 may be adapted to be operably coupled to an engine intake. The inner tube 240 may include an interior surface 246 and an exterior surface 248. The interior surface 246 of the inner tube 240 may define an inner tube passageway 252 through the inner tube 240 between the inner filter outlet end 242 and the inner engine intake end 244.

[0185] The pulse cleaning mechanism may include an outer tube 220 extending between an outer filter outlet end 222 and an outer engine intake end 224. The outer tube 220 may include an interior surface 226 and an exterior surface 228. The interior surface 226 of the outer tube 220 may define an outer tube passageway 232 through the outer tube 220 between the outer filter outlet end 222 and the outer engine intake end 224. The outer tube passageway 232 may receive the inner tube 240 (e.g., the PDSD No. 758.3090WOU1 inner filter outlet end 242) such that at least a portion of the interior surface 226 of the outer tube 220 faces at least a portion of the exterior surface 248 of the inner tube 240.

[0186] The inner tube 240 and the outer tube 220 may extend into the filtration system housing 210 and may be sealed to the filtration system housing 210 such that air passing through the inner tube passageway 252 must first pass through filter elements (e.g., as will be described further herein) located within the filtration system housing 210. The inner tube 240 and the outer tube 220 may extend into the housing 210 an equal distance (e.g., such that the inner filter outlet end 242 and the outer filter outlet end 222 are flush or even along the longitudinal axis 201). In other embodiments, the outer filter outlet end 222 may extend into the housing 210 farther than the inner filter outlet end 242 or the inner filter outlet end 242 may extend into the housing 210 farther than the outer filter outlet end 222.

[0187] Further, the outer tube 220 may include a pulse port 230 extending between the interior 226 and exterior surfaces 228 of the outer tube 220 (e.g., an opening in the outer tube 220) into the outer tube passageway 232. The pulse port 230 may be in fluid communication with a space between the inner 240 and outer tubes 220 such that gas directed into the pulse port 230 may take the shape of the gap between the inner 240 and outer tubes 220. For example, the area between the inner 240 and outer tubes 220 may form a ring (e.g., an annular shape) such that gas directed through the pulse port 230 forms a ring-shaped flow of gas towards the filter elements within the housing 210.

[0188] The filtration system housing 210 may include a first filter cartridge 280 (e.g., a safety filter element) surrounding the inner 240 and outer tubes 220, and a second filter cartridge 282 (e.g., a primary filter element) surrounding the first filter cartridge 280. As such, air entering the inlet 202 passes through the second filter cartridge 282 and then the first filter cartridge 280, before passing through the inner tube 240 to the engine intake. In some embodiments, the second filter cartridge 282 (e.g., the primary filter element) is designed to capture a large portion of the debris and sediment entering the inlet 202 and the first filter cartridge 280 (e.g., the safety filter element) is designed to capture dust should the primary element fail, or to capture dust while the primary element is removed for servicing. Each of the first and second filter cartridges 280, 282 may include a first and second cap 281, 283, respectively, to seal the filter cartridges such that air only passes through the filter elements of the first and second filter cartridges 280, 282 before entering inner tube 240. PDSD No. 758.3090WOU1

[0189] The pulse port 230 may be in fluid communication within the first filter cartridge 280 such that gas directed through the pulse port 230 (e.g., a pulse of gas) may apply pressure to an interior surface of the first filter cartridge 280 to, e.g., push debris and sediment off the exterior surface of the first filter cartridge 280. Additionally, in one or more embodiments, multiple pulse ports may be incorporated into the pulse cleaning mechanism to clean various filter elements located within the filtration system 130. For example the housing 210 may define an additional pulse port 235 positioned between the first and second filter cartridges 280, 282. As such, gas directed through the additional pulse port 235 may take the shape of the gap between the first and second filter cartridges 280, 282. For example, the area between the first and second filter cartridges 280, 282 may form a ring (e.g., an annular shape) such that gas directed through the additional pulse port 235 forms a ring-shaped flow between the first and second filter cartridges 280, 282.

[0190] The gas directed through the additional pulse port 235 may be used to clean debris and sediment from the second filter cartridge 282. For example, the gas directed through the additional pulse port 235 may apply a force to an interior surface of the second filter cartridge 282 to push sediment and debris off an exterior surface of the second filter cartridge 282. Additionally, the gas directed through each of the pulse port 230 and the additional pulse port 235 may be controlled individually or together. For example, in one or more embodiments, the pulse cleaning mechanism may include a valve (e.g., a diaphragm valve (e.g., with solenoid activation), a poppet valve, etc.) or other flow control elements (e.g., orifices, etc.) to control the velocity, volume, pressure, etc. of the gas directed through each of the pulse port 230 and the additional pulse port 235. Also, the gap between the first and second filter cartridges 280, 282 and the gap between the inner 240 and outer tubes 220 may be sized to precisely control the velocity of gas through each of the additional pulse port 235 and the pulse port 230, respectively.

[0191] Additionally, the filtration system 130 may include a pulse jet apparatus 260 in fluid communication with the pulse port 230 and the additional pulse port 235. The pulse jet apparatus 260 may be configured to direct gas through the pulse port 230 and / or the additional pulse port 235. For example, as described herein, the pulse jet apparatus 260 may direct gas through the pulse port 230 and the additional pulse port 235 independently or together. Either one or both pulse ports can be controlled and PDSD No. 758.3090WOU1 thus pulse port 230 can be used alone without additional pulse port 235 and similarly additional pulse port 235 can be used alone without pulse port 230.

[0192] Systems herein can obtain information (directly, indirectly, inferred, etc.) about equipment, equipment activities, and associated conditions and / or contaminants to allow the system to optimize filtration system cleaning parameters. By way of example, cleaning filters in the context of relatively light fluffy contaminants / debris (as merely one example - which could be encountered in forestry applications or some construction applications), can be benefited by pulsing during low engine airflow conditions (i.e., low engine rpm and load). In addition, less frequent pulsing with such contaminants can be optimal so that a significant mass of material is on the filter before pulsing so that agglomeration can aid ejection of the pulsed dust. In addition, high pulse energy may not be needed in some cases, such as with light fluffy debris and / or in other scenarios. As such, the system can use and / or lower a pulse energy related cleaning parameter in scenarios where a higher pulse energy is not needed as the use of lower pulse energies can result in longer filter life, assuming that each filter has a finite tolerance for pulsing. Systems herein can set and / or change cleaning parameter values accordingly in order to optimize filter cleaning.

[0193] As another example, dense contaminant, for example in dusty road construction environments, especially in geographic regions known for fine dust, can be benefited by a higher frequency of pulsing to prevent dust cakes from forming deep in the filter pleats that are difficult to remove. In addition, higher energy pulses can be optimal in the context of dense contaminants. As before, systems herein can use information about such contaminants and / or conditions to set and / or change cleaning parameter values accordingly in order to optimize filter cleaning.

[0194] Further, in the context of wet contaminants, it may be desirable to simply wait, in some scenarios where that is possible, until the collected material can dry out. As such, in some embodiments systems herein can use information indicating that such wetness is from a temporary event (such as based on weather or geospatial data or time of day data as impacting dew) and wait a short period of time and / or can delay the pulses until the next time the vehicle is operated. This type of scenario can also result in a pause event as described below.

[0195] As another example, when the system determines that the equipment is operating in a high soot environment (e.g., wildfire smoke, urban construction, close proximity to several other machines) such as based on geospatial and / or air quality PDSD No. 758.3090WOU1 data, the system can be configured to delay pulsing until it is absolutely needed. This can be beneficial as it is generally better to load the soot onto an existing dust cake than have a somewhat clean filter element where the soot would be loaded into the media itself. This type of scenario can result in a pause event as described below. In some cases, light pulses to only partially remove the dust cake can be beneficial and the system herein can be configured to set cleaning parameters accordingly.

[0196] As yet another example, the system can make some optimization adjustments to cleaning parameters such as pulse pressure based on altitude of machine. Thus, as can be seen, there are many potential optimizations of cleaning parameters that systems herein can make to optimize filtration system performance.

[0197] Systems herein can gather and / or receive many different types of information through many different channels to allow the system to optimize filtration system performance. Referring now to FIG. 4, a schematic view is shown of aspects of a system including information source categories in accordance with various embodiments herein. In specific, FIG. 4 illustrates a schematic view of a system designed for a piece of construction equipment 102, focusing on various information source categories 412 that influence the operation and functionality of the equipment's filtration system. These categories can include implements / attachments 414, activity / operation states 416, environmental conditions 418, and pause events 420. Information from each category can play a role (individually or in combination) in adjusting the filtration system's parameters to optimize performance and protect the equipment under varying conditions. However, it will be appreciated that other information source categories are also contemplated herein.

[0198] Implements / attachments 414 represent the tools or devices that can be connected to the construction equipment 102 to perform specific tasks. In some embodiments, data can originate directly from the implements, attachments, or headers themselves. In other embodiments, the system can infer information about the implement, attachment, or header using various factors such as season data, current geospatial location, engine load patterns, and the like further refining the system's adaptability to specific work site requirements. In some embodiments, the control circuitry can be configured to receive wired or wireless signals, including signals from RFID tags, about the implements or attachments. By way of example, such information can be received after the connection of the implement or attachment to the equipment, ensuring that the filtration system adapts to the specific operational PDSD No. 758.3090WOU1 needs dictated by the implement or attachment in use. Certain pulse cleaning parameter values can be ideal for construction equipment when certain implements / attachments 414 are in use. Thus, information regarding specific implements / attachments 414 being in use can allow the system to set values for pulse cleaning parameters optimally. In some embodiments, information linking specific implements / attachments 414 with specific pulse cleaning parameter values can be stored in memory of the system or otherwise accessed and then used to set optimal parameter values based on knowledge of implements / attachments 414 in use. Thus, in some embodiments, the filtration system's control circuitry is configured to receive and / or infer data from and about implements or attachments and adjust the pulse cleaning mechanism's parameters based on this data.

[0199] Activity / operation states 416 refer to the various activities or operations of the construction equipment in use. In various embodiments, the filtration system's control circuitry adjusts pulse cleaning parameters based on data regarding these activity or operation states. This can include engine state data, powered equipment action(s), hydraulic system usage, hydraulic pressure, vehicle weight, changes in vehicle weight, vibration data, and the filter loading rate of change. These adjustments ensure that the filtration system operates efficiently under varying operational demands. In some embodiments one or more operation state sensors and / or data from the same can be utilized by systems herein. Equipment operation state sensors, such as PTO shaft sensors, head engagement sensors, weight sensors, pressure sensors, and equipment height sensors, can provide additional data points for the control circuitry to consider when adjusting pulse cleaning parameters. This integration of sensor data ensures that the filtration system's operation is optimally tuned to the equipment's current state and operating environment. In some embodiments, information linking specific activity / operation states 416 with specific pulse cleaning parameter values can be stored in memory of the system or otherwise accessed and then used to set optimal parameter values based on knowledge of activity / operation states 416.

[0200] Environmental conditions 418 encompass the external factors that can affect the operation of the construction equipment, such as airborne soot levels, moisture content, and temperature. The filtration system can be configured to adjust its parameters based on these conditions to maintain optimal performance and protect the equipment's internal systems from environmental contaminants.

[0201] Pause events 420 are specific conditions or scenarios that trigger the filtration system to temporarily halt its pulse cleaning operations. These can include proximity to sensitive areas, specific contaminants or contaminant conditions, detection of specific vehicle fault codes, or operational states that require a reduction in filtration system activity to ensure safety or compliance with operational protocols.

[0202] Referring now to FIG. 5, a schematic view is shown of aspects of a system including some exemplary data inputs in accordance with various embodiments herein. In specific, FIG. 5 illustrates a schematic view of a system designed for a piece of construction equipment 102, illustrating an array of data inputs that inform and adjust the operation of the equipment's filtration system in accordance with various embodiments of the present invention. These data inputs can include direct interactions with other equipment 502, geolocation data from satellites 504 (or obtained from other sources), operator inputs 506, inputs through various Application Programming Interfaces (APIs) 508, such as a weather data 510 and / or an air pollutant data 512, inputs from a multitude of sensors 514, and data from an equipment associated data network 532.

[0203] In some embodiments, the system can be configured to receive data from other construction equipment 502 within a predetermined proximity. In some cases, the received data can relate to implements / attachments being used by other equipment, environmental conditions of the other equipment, activity or operational states of the other equipment, filter cleaning parameters being used by other equipment, and the like, allowing for greater data gathering to optimize cleaning of air filters and, in some cases, a collaborative approach to managing environmental impacts and optimizing operational efficiency across multiple pieces of equipment operating in the same area.

[0204] Operator input 506 allows the system to incorporate human intelligence and preferences into the filtration system's operation, enabling manual overrides or adjustments based on the operator's experience, immediate observations, and / or foresight into coming operational changes. In some embodiments, operator input 506 can include information on implements or attachments. In some embodiments, operator input 506 can include information on equipment activity or operation states. In some embodiments, operator input 506 can include information on environmental PDSD No. 758.3090WOU1 conditions. In some embodiments, operator input 506 can include a pause event command. In some embodiments, operator input 506 can include specific values for filter cleaning parameters.

[0205] In some embodiments, the system can be designed to receive data regarding the operator of the piece of construction equipment 102 and the cab conditions, ensuring that the filtration system's operation can be adjusted appropriately in view of the operator. For example, if the cab door is open, then this can mean that the equipment is not in active use and can serve as a pause event. Similarly, if a weight sensor associated with a seat in cab indicates that an operator is not sitting at the controls, then this can mean that the equipment is not in active use and can serve as a pause event.

[0206] Data regarding weather conditions around the piece of construction equipment 102 can be obtained via a weather data API 510, offering another layer of environmental intelligence to allow the system to optimize filtration system cleaning parameters in real-time. Data regarding air pollutants around the piece of construction equipment 102 can be obtained via an air pollutant data API 512. Such data can also be used to optimize filtration system cleaning parameters in real-time.

[0207] Many different sensors 514 can be included with systems herein and / or provide data to systems herein. Data from these sensors can be useful for dynamically adjusting the filtration system's cleaning parameters for optimal performance. Sensors herein can include both on-equipment sensors as well as off-equipment sensors. By way of example, FIG. 5 illustrates a humidity sensor 516, a temperature sensor 518, a particle sensor 520, a pressure sensor 522, a moisture sensor 524, a proximity sensor 526, a vibration sensor 528, and a weight sensor 530. However, these are only some exemplary sensors, and it will be appreciated that other sensors are also contemplated herein. For example, other sensors can include a shaft sensor (such as a PTO shaft sensor), a head engagement sensor, and an equipment height sensor, and each can provide real-time data on the equipment's operational state.

[0208] Some filtration systems can include a scavenger arrangement that is constructed and arranged to scavenge separated particulate material from both a filter precleaner arrangement and a filter assembly. The scavenger arrangement can include a scavenge fan. Data on the scavenge fan operation and / or temperature, such as from a temperature sensor associated with the scavenge fan, can be useful for monitoring the filtration system's health and efficiency, enabling appropriate selection of filtration PDSD No. 758.3090WOU1 system cleaning parameters. In some embodiments, pulse cleaning can be paused if the scavenge fan is not in operation.

[0209] The control circuitry can be configured to receive data regarding environmental conditions around the piece of construction equipment 102, including airborne soot levels, moisture content, work material moisture content, cement particle content, and salt content. This comprehensive environmental awareness enables the filtration system to adapt its operation to current and anticipated conditions.

[0210] In some embodiments, the system can have the capability to detect whether the equipment is indoors versus outdoors, which can be useful for setting filtration system cleaning parameters appropriately. For example, in some embodiments herein, the system can include an acoustic sensor, such as a microphone or the like, and can detect whether the equipment is indoors or outdoors based on characteristic sound patterns. In some embodiments, cleaning may desirably be paused when the equipment is indoors and this can serve as a pause event. In some embodiments, cleaning parameters can be set so that less noise is generated by the system when the equipment is indoors.

[0211] In some embodiments, an equipment associated data network 532, such as CANbus, can be utilized in facilitating communication and data exchange within the construction equipment 102 and potentially with other equipment. Data from such a network can be useful in adjusting the filtration system's parameters, ensuring that the system's operation is optimally tuned to the equipment's current state and external conditions. Such a network can facilitate the seamless integration of operational data, environmental conditions, and system diagnostics data to optimize the filtration system's performance. In some embodiments, data inputs regarding engine RPM, engine load, and movement speed of the piece of construction equipment 102 can be obtained from an equipment associated data network 532 and can be useful for inferring the equipment's operation state. This information can help to adjust the filtration system's parameters to match the equipment's current activity level and environmental exposure.

[0212] In some embodiments, the system can be configured to receive data regarding wheel speed and vehicle speed, and to evaluate the relationship between these two speeds. Such data can be received from an equipment associated data network 532 or from other sources. This can provide insight into the operational context of the PDSD No. 758.3090WOU1 equipment, affecting the filtration system's parameter adjustments. For example, a larger difference between wheel speed and vehicle speed may indicate different properties of the ground (e.g., solid, loose, wet, dry, etc.) which may be associated with varying levels of airborne dust and contaminants. In turn, varying levels of airborne dust and contaminants can indicate that specific cleaning parameters are optimal.

[0213] In some embodiments, data regarding activity and / or operation states can be received from the equipment associated data network 532 (as well as from various sensors herein). The system can be configured to monitor the amounts of time spent in different activity or operation states. Monitoring amounts of time spent in different activity or operation states allows for a nuanced understanding of the equipment's usage patterns, informing the filtration system's cleaning cycles and maintenance schedules.

[0214] In summary, FIG. 5 illustrates a network of data inputs and sensors that feed into the control circuitry of the construction equipment's filtration system. This network ensures that the system can dynamically adapt to both the internal operational state of the equipment and the external environmental conditions, optimizing performance of the filter cleaning system and protecting the equipment from harmful contaminants.

[0215] As referenced above, in some scenarios it can be desirable to temporarily pause cleaning pulses. As such, in some embodiments herein, the control circuitry can be configured to override a currently used pulsing scheme to temporarily pause pulse cleaning upon detecting a pause event. Pause events can last from seconds to minutes or longer, before the system resumes pulse cleaning. In some embodiments, pause events can be at least about 5, 10, 30, 45 or 60 seconds, or at least about 2, 5, 10, or 20 minutes or longer, or an amount of time falling within a range between any of the foregoing. In some cases, pause events can be indefinite and remain in place until the triggering event or condition is reversed.

[0216] Pause events can be varied in nature. In some embodiments, pause events can be based on a condition or circumstance that is detected or a particular contaminant or contaminant condition. In other embodiments, pause events can be based on receiving a signal (wired or wireless) relating to a pause event. In some embodiments, pause events can be based on human input, such as input from a system operator. In some embodiments, pause events can be based on proximity to something such as a PDSD No. 758.3090WOU1 building, a beacon, a particular work zone, another piece of equipment such as other construction equipment, a human, dust control equipment, and the like. The proximity threshold value can be predetermined or dynamically determined.

[0217] Referring now to FIG. 6, a schematic view of aspects of a system is shown in accordance with various embodiments herein. FIG. 6 specifically provides a view of a piece of construction equipment 102 in proximity to a building 602, illustrating the concept of building proximity 604 (and more generally proximity to an object of significance, a person, etc.) and its implications for the operation of the equipment's filtration system in accordance with various embodiments of the present invention. This figure visually represents how the filtration system adapts to proximity crossing a threshold value.

[0218] As before, the piece of construction equipment 102 is equipped with a filtration system comprising control circuitry, a filter housing, and a pulse cleaning mechanism. This system is designed to maintain the filter element's cleanliness within the filter housing, ensuring optimal performance and longevity of the equipment's engine or other systems requiring filtered air.

[0219] If the proximity 604 crosses a threshold value, then a pause event can be triggered, which temporarily halts the pulse cleaning mechanism. This feature is designed to adapt the equipment's operation to sensitive environments, such as reducing noise associated with pulse cleaning near buildings. However, reactions to proximity crossing a threshold value can vary depending on the nature of what object is within the proximity. By way of example, proximity to a known source of dust and / or contaminants (such as a loading area) can result in adjusting cleaning parameters so that pulse cleaning is more frequent and / or more intense.

[0220] There are many potential scenarios in which filtration system pulse cleaning may desirably be paused. By way of example, in some embodiments, the system can be responsive to various operational conditions, such as receiving a vehicle fault code, which could relate to engine issues or brake issues, indicating the system's integrated approach to equipment management and safety. In some embodiments, a pause event can be triggered by detecting the equipment's hood being open, as an example of the system's ability to respond to direct interactions with the equipment's components.

[0221] In various embodiments, the filtration system may use one or more base, default, or template sets of cleaning parameters and then vary the same based on detected conditions. FIG. 7 provides a schematic view of a piece of construction PDSD No. 758.3090WOU1 equipment 102, illustrating the integration of a pulse cleaning parameter table of values 702, which can be stored in memory of the system and utilized for operation and adaptability of the equipment's filtration system in accordance with various embodiments of the present invention.

[0222] The pulse cleaning parameter table of values 702 can contain values for a range of parameters that can be adjusted to optimize the pulse cleaning mechanism's operation. In some embodiments, a set of values for parameters (e.g., set X, Y, or Z) that are optimized for different conditions (e.g., conditions A, B, or C) or equipment activities can be applied based on detection of conditions and / or activities of the equipment. The set of values can include values for from 1 to 10 or more different specific cleaning parameters. Exemplary cleaning parameters can include, but are not limited to, a pressure drop trigger threshold change, pulse cleaning frequency, pulse cleaning pattern, peak pressure of a pulse wave, pulse duration, pulse energy, pulse pattern, number of valves, valve synchrony parameter, and non-pulse cleaning parameters. The filtration system can dynamically adjust parameter values of its cleaning cycles (either individual parameters or switching to a different set of parameters) based on real-time data and predefined conditions, ensuring optimal cleaning operation and prolonged filter life.

[0223] In some embodiments, selection by the system of appropriate default pulse cleaning parameter data can be based on the data from and / or about the implement, the attachment, or the header. This capability ensures that the filtration system is immediately optimized for the specific equipment configuration and operational requirements.

[0224] In some embodiments, selection by the system of appropriate default pulse cleaning parameter values (individual values or sets of values) can be based on a broader set of considerations, including the type of the installed filter element, data on dust / particulates, type of soil, and construction equipment activity. This comprehensive approach allows the system to adapt to the environmental conditions and the nature of the work being performed, enhancing the filtration efficiency and equipment protection.

[0225] In some embodiments, selection by the system of appropriate default pulse cleaning parameter data can be based on ambient conditions and moisture status of the ground upon which the construction equipment is operating. This feature ensures that PDSD No. 758.3090WOU1 the filtration system is responsive to environmental factors that could affect its performance and the need for filter cleaning.

[0226] In some embodiments, selection by the system of appropriate default pulse cleaning parameter data can be based on a combination of factors, including ambient conditions, air moisture status, ground moisture status, data regarding an installed filter element, particulates, and construction equipment activity.

[0227] In summary, FIG. 7 illustrates the use of pulse cleaning parameter table data by the filtration system of the piece of construction equipment. This data, in conjunction with the system's control circuitry, enables a highly adaptive and responsive approach to filter maintenance, ensuring that the equipment operates efficiently and effectively in a variety of conditions and operational scenarios.

[0228] FIG. 8 is a schematic view of data flow in accordance with various embodiments herein. In specific, FIG. 8 illustrates data flow within and external to a piece of construction equipment 102, showcasing the integration of various communication and computing components that facilitate real-time data exchange and system optimization of cleaning parameters in accordance with various embodiments of the present invention. In addition, FIG. 8 illustrates the interconnectedness of the construction equipment in some embodiments with broader data networks and computing resources, enabling advanced functionality and remote management capabilities.

[0229] FIG. 8 shows a piece of construction equipment 102, equipped with a filtration system herein that generates and / or utilize operational data in order to select appropriate filtration cleaning system parameters. This equipment is capable of communicating with external systems to receive updates, send alerts, and adjust its operation based on real-time data and remote inputs.

[0230] In some embodiments, a communication gateway 810 can serve as an interface for data exchange between the construction equipment 102 and external networks. It can facilitate the transmission of data to and from the equipment, enabling remote monitoring, diagnostics, and system adjustments.

[0231] In this example, the piece of construction equipment 102 is shown within a construction work zone 816. The construction work zone 816 represents the operational environment of the construction equipment 102, which may include multiple pieces of equipment, personnel, and infrastructure. Data gathered within this zone, such as equipment status, environmental conditions, and operational metrics, PDSD No. 758.3090WOU1 can be communicated through the gateway 810 for various purposes, including coordination, safety monitoring, and efficiency optimization.

[0232] In some embodiments, a cellular tower 820 can be a component of the communication infrastructure, enabling wireless data transmission between the construction equipment 102 (such as directly or via the communication gateway 810) and broader networks, including the internet and cloud computing environments. This connectivity ensures that the equipment can be monitored and managed from remote locations.

[0233] A cloud computing environment 822 provides scalable computing resources and services that support the processing, analysis, and storage of data from the construction equipment 102. This environment enables advanced data analytics, predictive maintenance, and other intelligent services that enhance the equipment's performance and reliability.

[0234] These components represent the various endpoints and intermediaries involved in the data flow. The remote computing device 828 and communications device 830 allow users, such as equipment operators, maintenance personnel, and management, to interact with the equipment's data and control systems remotely and / or locally. A server 832, often part of a larger data center within the cloud computing environment 822, processes and manages the data flow, ensuring that relevant information is accessible and actionable.

[0235] A database 834 can serve as the repository for collected / stored data, including operational parameters, system diagnostics, environmental conditions, and user inputs. This centralized storage enables historical data analysis, trend identification, and the development of predictive models to improve equipment operation and maintenance strategies.

[0236] The remote location 840 symbolizes the geographical flexibility afforded by the system, allowing stakeholders to monitor and manage the construction equipment 102 from virtually anywhere. This capability is particularly valuable for fleet management, remote diagnostics, and ensuring compliance with operational best practices and regulatory requirements.

[0237] FIG. 9 is a schematic view of work site locations in accordance with various embodiments herein. FIG. 9 provides a schematic view of a construction environment, illustrating the deployment of pieces of construction equipment 102 within a defined work area 902. FIG. 9 shows multiple pieces of construction equipment 102, each PDSD No. 758.3090WOU1 equipped with technology to communicate with geolocation satellites 504 and other systems to determine their precise locations within the work area 902.

[0238] The work area 902 represents the overall operational environment or project site where the construction activities are taking place. It is within this area that specific work site locations, such as work site location one 908 and work site location two 910, are designated for various construction tasks.

[0239] Work site location one 908 and work site location two 910 exemplify the concept of task-specific sites within the work area 902. The control circuitry of the construction equipment 102 is configured to receive data regarding the proximity of the equipment to these or other task-specific sites, adjusting filtration system cleaning parameters based on the equipment's location relative to the designated work sites. By way of example, a loading area is an example of a task-specific site. Such a loading area can be a component of the work area 902, serving as a designated location for loading and unloading materials. The ability of the construction equipment 102 to recognize its proximity to such a critical area allows for automated adjustments to its filter cleaning parameters, thereby enhancing filter cleaning efficiency.

[0240] In summary, FIG. 9 illustrates the integration of geolocation technology with filter cleaning operations within a work area, emphasizing the importance of precise location data in optimizing cleaning operations across various work site locations. By leveraging real-time geolocation data, the system ensures that cleaning parameters can be optimized while the equipment is at specific work site locations.

[0241] FIG. 10 is a schematic view of geographic regions in accordance with various embodiments herein. This figure highlights the division of a broader area into distinct geographic areas, each with potential implications for the operation and management of construction equipment and specifically the filter cleaning operations thereof.

[0242] The geolocation satellite 504 provides the positioning data necessary for identifying and distinguishing between different geographic areas. The first geographic area 1002 and the second geographic area 1004 represent distinct geographic regions. Each area can be defined by specific geospatial boundaries and characterized by unique operational or environmental conditions that may affect the filtration cleaning operations of construction equipment. For example, a piece of equipment operating within the first geographic area 1002 might require different pulse cleaning parameters than when it operates within the second geographic area 1004, due to variations in air quality, dust levels, or other environmental factors. PDSD No. 758.3090WOU1

[0243] In some embodiments, the system can be configured to infer information regarding an equipment operation state of the piece of construction equipment based on its geographic location. As such, the system can adjust the operation of the construction equipment, including its filtration system and cleaning parameters of the same, based on the equipment's presence within either the first geographic area 1002 or the second geographic area 1004. For example, certain geographic areas may require more aggressive cleaning operations to achieve desired filtration system performance.

[0244] As another example, the concept of altitude-based cleaning parameter adjustment is relevant to geospatial regions, as different geographic areas may have significantly different altitudes. These altitude differences can affect engine performance, air filtration needs, and other operational aspects of construction equipment, necessitating adjustments to cleaning parameters to optimize filtration system efficiency.

[0245] Referring now to FIG. 11, a schematic view of components of a filtration control system 1110 is shown in accordance with various embodiments herein. It will be appreciated, however, that a greater or lesser number of components can be included with various embodiments and that this schematic diagram is merely illustrative.

[0246] In this example, the system 1110 can include a sensor module 1112 and a housing 1114. The sensor module 1112 can include a first sensor 1194, which can be any of the sensors described above. In this example, the sensor module 1112 can also include a second sensor 1196, which can be any of the sensors described above.

[0250] A power supply circuit 1102 can be disposed within the housing 1114. In some embodiments, the power supply circuit 1102 can include various components including, but not limited to, a rectifier 1104, a capacitor, a power-receiver such as a wireless power receiver, a transformer, a battery, and the like. In some embodiments, the power supply circuit 1102 can be in electrical communication with a source of power 1120. The source of power 1120 can either be an AC or DC power source, with implications for the other components of the power supply circuit 1102 (such as a rectifier 1104 typically not being needed when the source of power 1120 is DC).

[0251] In some embodiments the system 1110 can include an output device 1106 disposed on the housing 1114. The output device 1106 can include various components for visual and / or audio output including, but not limited to, lights (such as LED lights), a display screen, a speaker, and the like. In some embodiments, the output device can be used to provide notifications or alerts to a system user such as current system status, an indication of a problem, a required user intervention, a proper time to perform a maintenance action, or the like. It will be appreciated, however, that in various embodiments notifications and / or alerts can be provided electronically to another device or component, such as a vehicle system, a remote system, a driver device, or the like. In some embodiments, the output device 1106 can also serve as an input device, such as in the case of a touchscreen interface. PDSD No. 758.3090WOU1

[0252] In various embodiments the system 1110 can include memory 1108 and / or a memory controller disposed within the housing 1114. The memory can include various types of memory components including dynamic RAM (D-RAM), read only memory (ROM), static RAM (S-RAM), disk storage, flash memory, EEPROM, battery -backed RAM such as S-RAM or D-RAM and any other type of digital data storage component.

[0253] In various embodiments the system 1110 can include a clock circuit 1111 disposed within the housing 1114. In some embodiments, the clock circuit 1111 can be integrated with the control circuit 1190. While not shown in FIG. 11, it will be appreciated that various embodiments herein can include a data / communi cation bus to provide for the transportation of data between components. In some embodiments, an analog signal interface can be included. In some embodiments, a digital signal interface can be included.

[0254] In various embodiments the system 1110 can include a communications circuit 1113. In various embodiments, the communications circuit 1113 can include components such as an antenna 1115, amplifiers, filters, digital to analog and / or analog to digital converters, and the like. In some embodiments, the antenna 1115 can be configured for use with RFID communications. For example, the system can include an RFID tag reader and the antenna 1115 can be part of the RFID tag reader. The RFID tag reader can send and receive radio signals to and from one or more RFID tags 1150 that can be disposed on an implement or attachment and can store and then transmit data regarding the same such as equipment type, model, serial number, etc. RFID tags herein can be passive, meaning they have no battery and rely on the reader's signal to power up, or active, meaning they have their own power source and can transmit data continuously.

[0255] Filter elements can have differing properties such as being made of different materials, different pore sizes, different pleat parameters, and the like that may make them behave differently in terms of filter loading and other functional properties. Also, different particulates may have different impacts on filter elements. For example, relatively larger debris might result in face plugging more so than smaller debris. Furthermore, the type of dirt and / or construction activity being performed can also impact the type of particulates encountered, the relative amount of particulates, PDSD No. 758.3090WOU1 filter loading characteristics, and the like. As such, information about the filter element, particulates, type of dirt and activity can all influence the efficacy of different pulsing cleaning parameters. In some embodiments, the system can store one or more lookup tables that include as variables information about one or more of filter elements (including part numbers, model numbers, etc.), particulates, type of dirt, activity and the like and link the same with default pulse cleaning parameters that are ideally suited for the same.

[0256] In some embodiments, the system can read information from the filter element for various purposes. In some cases, the system can read information from the filter element using an RFID tag that is associated with the filter element. However, information can also be read from the filter element in other ways. The system can use the information read in various ways. For example, in some embodiments, the system can read information from the filter element to ensure that it is recognized as a type that is suitable for pulse cleaning. If it is a type that is suitable for pulse cleaning, then the system can proceed with pulse cleaning operations herein. However, if it is not a type suitable for pulse cleaning, then pulse cleaning can be stopped / skipped, request operator override, and / or provide a warning or issue an alert that pulse cleaning is not being performed.

[0257] In some embodiments, every filter can have a rating as to how many pulses or how many pulses under a variety of pulse conditions are allowed. The system herein can track the total number of pulses for a given filter element and then indicate end of life (actual or at an estimated future time) to make sure the filter element is not over pulsed and damaged resulting in possible equipment damage.

[0258] In some embodiments, if information about the filter element cannot be read, then the system can default to a set of basic pulse cleaning parameters. In some embodiments, the system can read information from the filter element (such as a digital key or other data) to ensure that it is not a counterfeit product. If it is counterfeit, then then the system can perform one or more steps such as ceasing operation, turning off pulse cleaning, and defaulting to a set of basic pulse cleaning parameters.

[0259] In some embodiments, the communications circuit 1113 can be in wired and / or wireless communication with an implement or attachment and / or construction equipment 102 or other equipment. By way of example, in some embodiments, the PDSD No. 758.3090WOU1 communications circuit 1113 or a component thereof can be in communication with a CANbus network on a piece of construction equipment 102.

[0260] In various embodiments the system 1110 can also include a geolocation chip or circuit 1122. Geolocation data can include latitude / longitude coordinates, or other location identifying information such as a nearest address, nearest landmark, etc. As used herein, the term “geolocation data” shall include reference to all location identifying data, unless the context dictates otherwise.

[0261] In some cases, geolocation data can be derived from a satellite-based geolocation system. Such systems can include, but are not limited to, GPS L1 / L2, GLONASS G1 / G2, BeiDou B1 / B2, Galileo El / E5b, SB AS, or the like. In various embodiments, the geolocation circuit 1122 can include appropriate signal receivers or transceivers to interface with a satellite and / or the geolocation circuit can interface with and / or receive data from a separate device or system that provides geolocation data or derives geolocation data from a satellite or other device. However, it will be appreciated that geolocation data herein is not limited to just that which can be received from or derived from interface with a satellite. Geolocation data can also be derived from addresses, beacons, landmarks, various referential techniques, IP address evaluation, and the like.
