Description

Technical Field

[0001] This application relates to the field of lighting energy-saving control technology, and more specifically, to a mobile lighting vehicle lighting energy-saving control system and method. Background Technology

[0002] Mobile lighting vehicles are commonly used for temporary lighting scenarios such as municipal emergency repairs, nighttime construction, temporary loading and unloading, and emergency support. They are typically powered by energy storage batteries to supply power to multiple lighting fixtures and can be supplemented by solar panels. During use, it is necessary to balance the working illumination, safety lighting, and remaining battery life.

[0003] The existing energy-saving control methods for mobile lighting vehicles mainly rely on manual adjustment, timed dimming, fixed power level adjustment, or overall power reduction based on the remaining battery power. Although these methods can reduce some energy consumption, they usually do not take into account the operational attributes of different lighting areas, actual illuminance, target illuminance, minimum illuminance limit, and the correspondence between lighting fixtures and lighting areas.

[0004] In actual temporary lighting scenarios, the illumination requirements for the core work area, the access control area, and the edge lighting area are not the same. If the power of the lamps is reduced uniformly based on the remaining battery power, the illumination in the core work area or the access control area may be lower than the safety requirements. If the power is reduced locally based on whether the illumination is sufficient, the gap between the remaining lighting time and the available battery power may be ignored, resulting in the mobile lighting vehicle being unable to stably support the lighting until the planned end time.

[0005] In addition, existing control methods usually lack recovery and compensation processing based on the verified illuminance after power reduction. When the power reduction causes the illuminance of some lighting areas to fall below the minimum illuminance limit, it is difficult to restore the output power of the corresponding lamps in a timely manner, and it is also difficult to continue to release the power that can be reduced in low priority areas, thus resulting in a lack of closed-loop coordination between energy-saving control and lighting safety.

[0006] Therefore, how to determine the power reduction control object and control sequence during the temporary lighting process of mobile lighting vehicles by combining battery endurance, lighting area priority, illuminance margin and the correspondence between lighting fixture areas, and how to restore or compensate by checking the illuminance after the output power is corrected, has become a technical problem that needs to be solved.

[0007] In view of this, this application proposes a mobile lighting vehicle lighting energy-saving control system and method to solve the above problems. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the purpose of this application is to provide a method and system for energy-saving control of mobile lighting vehicles. By collecting data on the remaining battery power of the mobile lighting vehicle, the current output power of the lighting fixtures, the remaining lighting duration, the actual illuminance of the lighting area, and the correspondence between the lighting fixtures and the lighting area, and combining the lighting area priority, target illuminance, minimum illuminance limit, and remaining battery life, a power reduction control sequence for the lighting fixtures is determined. After the output power is corrected, the output power is restored or reduced in compensation based on the verified illuminance, thereby achieving the goal of maintaining safe illuminance in different lighting areas while reducing lighting energy consumption.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] A method for energy-saving control of lighting on a mobile lighting vehicle includes:

[0011] Collect mobile lighting vehicle operation observation data, which includes the remaining battery power, the current output power of each lighting fixture, the remaining lighting duration, the type of each lighting area, the actual illuminance of each lighting area, and the correspondence between lighting fixtures and areas;

[0012] The priority of each lighting area is determined based on its type, and the target illuminance and minimum illuminance limit are determined based on the lighting requirements of the current lighting task and historical qualified lighting records. This generates a lighting area status result that includes the lighting area priority, actual illuminance, target illuminance, and minimum illuminance limit.

[0013] Based on the current output power of each lighting fixture, the remaining lighting time, and the remaining battery power, determine the power required for continuous lighting and the available lighting power. Based on the comparison between the power required for continuous lighting and the available lighting power, generate a battery gap result that includes the battery status and the battery gap.

[0014] Based on the actual illuminance, target illuminance, minimum illuminance limit and lighting area priority in the lighting area status results, determine the illuminance margin and illuminance status, and combine the endurance gap results and the correspondence between the lighting fixtures and the lighting area to determine the lighting fixture power reduction control sequence.

[0015] The output power of each lighting fixture is corrected according to the lighting fixture power reduction control sequence. After the output power is corrected, the verification illuminance of each lighting area is collected. Based on the verification illuminance, the output power is restored and compensated for reduction, and the energy-saving control result of the lighting vehicle is generated.

[0016] Furthermore, methods for determining illuminance margin and illuminance state include:

[0017] When the actual illuminance is greater than the target illuminance, the difference between the actual illuminance and the target illuminance is defined as the target illuminance margin; when the actual illuminance is less than or equal to the target illuminance, the target illuminance margin is defined as zero. When the actual illuminance is greater than the minimum illuminance limit, the difference between the actual illuminance and the minimum illuminance limit is defined as the illuminance margin that can be reduced; when the actual illuminance is less than or equal to the minimum illuminance limit, the illuminance margin that can be reduced is defined as zero. When the illuminance margin that can be reduced is zero, the illuminance state is defined as the power reduction prohibition zone. When the illuminance margin that can be reduced is greater than zero and the target illuminance margin is zero, the illuminance state is defined as the minimum maintenance zone. When the target illuminance margin is greater than zero, the illuminance state is defined as the illuminance redundancy zone.

[0018] Furthermore, the methods for generating the range gap results include:

[0019] The current total power of the lighting fixtures is obtained by adding up the current output power of each fixture. The remaining lighting time is converted into remaining lighting hours in hours, and the remaining lighting hours are multiplied by the current total power of the fixtures to obtain the power required for continuous lighting. When the remaining battery power is greater than the battery reserve power, the difference between the remaining battery power and the battery reserve power is determined as the available lighting power. When the remaining battery power is less than or equal to the battery reserve power, the available lighting power is determined to be zero. When the power required for continuous lighting is greater than the available lighting power, the difference between the two is determined as the endurance gap, and the endurance status is determined to have an endurance gap. When the power required for continuous lighting is less than or equal to the available lighting power, the endurance gap is determined to be zero, and the endurance status is determined to have no endurance gap.

[0020] Furthermore, the method for determining the luminaire power reduction control sequence includes:

[0021] Based on the correspondence between lighting fixture areas, candidate groups for power reduction are formed. Based on the remaining battery life, illuminance status, and available illuminance reduction margin, candidate groups for power reduction are selected from these candidate groups to participate in the power reduction judgment. These candidate groups are then sorted to obtain the power reduction candidate group ranking order, and the power reduction capacity of each candidate group is determined. The product of the reduceable power and the remaining lighting hours is determined as the reduceable electricity consumption. According to the power reduction candidate group ranking order, the corresponding lighting area, the lighting fixture number within the group, the reduceable power, and the reduceable electricity consumption are combined to form a lighting fixture power reduction control sequence.

[0022] Furthermore, when the endurance gap result indicates that there is no endurance gap, the power reduction candidate group corresponding to the illuminance redundancy area and having a illuminance reduction margin greater than zero is determined as the power reduction candidate group participating in the power reduction judgment; when the endurance gap result indicates that there is an endurance gap, the power reduction candidate group corresponding to the illuminance redundancy area and the minimum maintenance area and having a illuminance reduction margin greater than zero is determined as the power reduction candidate group participating in the power reduction judgment; the power reduction candidate group corresponding to the prohibited power reduction area does not participate in the power reduction judgment.

[0023] Furthermore, methods for obtaining the ranking of candidate power reduction groups include:

[0024] The candidate groups for power reduction corresponding to the illuminance redundancy area are ranked before the candidate groups for power reduction corresponding to the minimum maintenance area; when the illuminance status is the same, they are sorted from low to high according to the priority of the lighting area; when the priority of the lighting area is the same, they are sorted from large to small according to the illuminance reduction margin; when the illuminance reduction margin is the same, they are sorted from large to small according to the sum of the current output power of the lighting fixtures in the power reduction candidate groups.

[0025] Furthermore, methods for determining the power reduction include:

[0026] The control boundary illuminance is determined based on the illuminance status of the lighting area corresponding to the candidate group for power reduction. When the corresponding lighting area is an illuminance redundancy area, the target illuminance is used as the control boundary illuminance. When the corresponding lighting area is a minimum maintenance area, the minimum illuminance limit is used as the control boundary illuminance. When the actual illuminance is greater than the control boundary illuminance and the actual illuminance is greater than zero, the ratio of the difference between the actual illuminance and the control boundary illuminance to the actual illuminance is determined as the allowable reduction ratio. The product of the allowable reduction ratio and the sum of the current output power of the lighting fixtures in the candidate group for power reduction is determined as the power that can be reduced. When the actual illuminance is less than or equal to the control boundary illuminance, the power that can be reduced is determined to be zero.

[0027] Furthermore, when correcting the output power of each lighting fixture according to the lighting fixture power reduction control sequence, if the endurance gap result indicates that there is no endurance gap, the power that can be reduced in the corresponding power reduction candidate group of the illuminance redundancy area is taken as the actual power reduction, and the output power of the lighting fixtures in the corresponding power reduction candidate group is reduced according to the actual power reduction; if the endurance gap result indicates that there is an endurance gap, the endurance gap is determined as the amount of electricity to be eliminated, and the power reduction candidate group is processed sequentially according to the lighting fixture power reduction control sequence. The actual power reduction is determined based on the comparison result between the power that can be reduced and the amount of electricity to be eliminated in the currently processed power reduction candidate group, and the output power of the lighting fixtures in the corresponding power reduction candidate group is reduced according to the actual power reduction.

[0028] Furthermore, methods for reducing the output power of lighting fixtures in the corresponding power reduction candidate group based on actual power reduction include:

[0029] When the same power reduction candidate group includes one lighting fixture, the actual power reduction is allocated to that lighting fixture; when the same power reduction candidate group includes two or more lighting fixtures, the actual power reduction is allocated according to the proportion of the current output power of each lighting fixture in the group to the sum of the current output power of the corresponding power reduction candidate group; when the output power of any lighting fixture after the actual power reduction is allocated is less than the minimum allowable output power, the output power of the corresponding lighting fixture is adjusted to the minimum allowable output power, and the power that has not been reduced is further allocated to other lighting fixtures in the same power reduction candidate group that have not reached the minimum allowable output power.

[0030] Furthermore, the method for performing output power restoration and compensation reduction processing based on the verified illuminance includes:

[0031] After output power correction, the verification illuminance of each lighting area is collected; when there is a lighting area with verification illuminance less than the corresponding minimum illuminance limit, the corresponding lighting fixtures are restored to their output power before correction according to the priority of the lighting area from high to low, and the amount of electricity to be compensated is determined according to the restored increased power and the remaining lighting hours; the remaining power that can be reduced is obtained by subtracting the actual reduced power from the power that can be reduced in each power reduction candidate group, and negative values ​​are taken as zero; according to the luminaire power reduction control sequence, the power reduction candidate groups with priority lower than the restored lighting area, verification illuminance greater than or equal to the corresponding minimum illuminance limit and remaining power that can be reduced are selected, and the compensation reduction is performed according to the amount of electricity to be compensated.

[0032] This application provides a mobile lighting vehicle illumination energy-saving control system, and the implementation of the mobile lighting vehicle illumination energy-saving control method includes:

[0033] The observation and acquisition module is used to collect the operation observation data of the mobile lighting vehicle. The operation observation data includes the remaining battery power, the current output power of each lighting fixture, the remaining lighting time, the type of each lighting area, the actual illuminance of each lighting area, and the correspondence between lighting fixtures and areas.

[0034] The area calibration module is used to determine the priority of lighting areas according to the type of each lighting area, and to determine the target illuminance and the minimum illuminance limit according to the lighting requirements of the current lighting task and the historical qualified lighting records, and generate the lighting area status results including lighting area priority, actual illuminance, target illuminance and minimum illuminance limit;

[0035] The battery life determination module is used to determine the power required for continuous lighting and the available power for lighting based on the current output power of each lighting fixture, the remaining lighting time, and the remaining battery power. Based on the comparison between the power required for continuous lighting and the available power for lighting, it generates a battery life gap result that includes the battery life status and the battery life gap.

[0036] The power reduction decision module is used to determine the illuminance margin and illuminance status based on the actual illuminance, target illuminance, minimum illuminance limit and lighting area priority in the lighting area status results, and to determine the illuminance power reduction control sequence by combining the endurance gap results and the correspondence between the luminaire area;

[0037] The correction and verification module is used to correct the output power of each lighting fixture according to the lighting fixture power reduction control sequence. After the output power is corrected, the verification illuminance of each lighting area is collected. Based on the verification illuminance, the output power is restored and compensated for reduction, and the energy-saving control result of the lighting vehicle is generated.

[0038] The technical effects and advantages of the mobile lighting vehicle energy-saving control system and method proposed in this application are as follows:

[0039] This application generates lighting area status results by collecting data on remaining battery power, current output power of lighting fixtures, remaining lighting duration, actual illuminance of the lighting area, and the correspondence between lighting fixture areas. It also generates endurance gap results based on the power required for continuous lighting and the available power for lighting, enabling energy-saving control to consider both lighting demand and remaining endurance, and reducing deviations caused by power adjustment based solely on instantaneous power or manual dimming.

[0040] This application determines the illuminance margin and illuminance status based on the actual illuminance, target illuminance, and minimum illuminance limit. It also determines the luminaire power reduction control sequence by combining the lighting area priority, the endurance gap result, and the correspondence between luminaire areas. This allows the power reduction processing to be applied first to lighting areas with illuminance redundancy and lower priority, thereby reducing the risk of insufficient illuminance in the core work area and the passage guarantee area.

[0041] This application collects the verification illuminance of each lighting area after correcting the output power of the lighting fixtures. For lighting areas where the verification illuminance is lower than the corresponding minimum illuminance limit, the output power is restored, and compensation reduction is performed in low-priority lighting areas that meet the conditions. This makes the power reduction control form an illuminance verification closed loop, reducing lighting energy consumption while maintaining the minimum lighting requirements of each lighting area.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Example 1:

[0048] See Figure 1 and Figure 2 This embodiment provides a method for energy-saving control of lighting from a mobile lighting vehicle, including:

[0049] The system collects data on the remaining battery power of the mobile lighting vehicle, the current output power of the lighting fixtures, the remaining lighting duration, and the actual illuminance of each lighting area. It then determines the power gap between the power required for continuous lighting and the available power for lighting. Based on the comparison between the actual illuminance of each lighting area and the target illuminance and the minimum illuminance limit, it determines the illuminance margin. Finally, based on the priority of the lighting area and the illuminance margin, it determines the power reduction control sequence for the lighting fixtures and corrects the output power of the lighting fixtures according to the power reduction control sequence.

[0050] Mobile lighting vehicles are lighting equipment that can be moved to temporary lighting sites and provide work lighting. They include trailer-mounted, vehicle-mounted, towed, and mobile chassis-borne lighting equipment. Mobile lighting vehicles are equipped with solar panels and energy storage batteries. The solar panels charge the energy storage batteries, which in turn supply power to the lighting fixtures. The lighting fixtures are mounted on the mobile lighting vehicle's poles, frames, or mounting brackets and provide illumination toward the work area. Their output power can be adjusted according to control commands.

[0051] After the mobile lighting vehicle enters the lighting operation, it collects the vehicle's operation observation data according to the control cycle. The control cycle is the time period corresponding to the mobile lighting vehicle performing one energy-saving control judgment. The vehicle's operation observation data includes the remaining battery power, the current output power of each lighting fixture, the start time of the control cycle, the planned end time of lighting, the remaining lighting duration, the remaining lighting hours, the type of each lighting area, the actual illuminance of each lighting area, and the correspondence between lighting fixtures and areas.

[0052] The duration of the control cycle is determined based on the lighting control response time and illuminance acquisition interval of the mobile lighting vehicle. The lighting control response time is the time from the issuance of the lighting control command to the output power of the lighting fixture reaching the commanded power, obtained from the lighting fixture drive record or debugging record. The illuminance acquisition interval is the time interval between two adjacent illuminance value acquisition times, obtained from the acquisition settings of the illuminance acquisition device. The larger value between the lighting control response time and the illuminance acquisition interval is taken as the cycle determination duration. When the cycle determination duration is less than or equal to ten seconds, the control cycle is thirty seconds; when the cycle determination duration is greater than ten seconds and less than or equal to thirty seconds, the control cycle is one minute; when the cycle determination duration is greater than thirty seconds, the control cycle is five minutes.

[0053] At the start of the control cycle, the remaining battery power of the mobile lighting vehicle is collected. The remaining battery power is the remaining stored energy in the energy storage battery at the start of the control cycle, and the unit of measurement is watt-hour. The remaining battery power is obtained from at least one of the energy storage battery management records, battery voltage and current acquisition records, and mobile lighting vehicle existing power display records.

[0054] When the remaining battery power is determined by the battery voltage and current acquisition records, the most recently known battery power is used as the initial power. The voltage value, current value and time interval of adjacent sampling times are read according to the sampling time sequence. The charging power or discharging power corresponding to each time interval is calculated. The charging power is added to the initial power and the discharging power is deducted from the initial power to obtain the remaining battery power at the start of the control cycle. When the remaining power is directly provided by the energy storage battery management record, the remaining power in the energy storage battery management record is read first.

[0055] The current output power of each lighting fixture is collected. The current output power of each lighting fixture is the actual electrical power of each lighting fixture at the beginning of the control cycle, and the unit of measurement is watts. When the lighting fixture driver power supply can output power, the output power record of the lighting fixture driver power supply is read as the current output power of the corresponding lighting fixture. When the lighting fixture driver power supply does not output power, the voltage and current values ​​in the power supply circuit of the corresponding lighting fixture are collected. The product of the voltage and current values ​​is taken as the current output power of the corresponding lighting fixture, and the lighting fixtures are numbered and recorded according to the installation order of the lighting fixtures on the mobile lighting vehicle, the lighting fixture control address, or the power supply circuit number.

[0056] The system reads the start time of the control cycle and the planned end time of the lighting. The planned end time of the lighting is the time when the current lighting task is expected to stop, which is determined by at least one of the following: the work plan input, the on-site lighting task record, and the manually set lighting end time. The time difference between the planned end time of the lighting and the start time of the control cycle is determined as the remaining lighting duration. The remaining lighting duration is converted into remaining lighting hours in hours. When the planned end time of the lighting is earlier than or equal to the start time of the control cycle, the control cycle is determined as the lighting task end cycle, the endurance gap calculation is no longer performed, and the current output power of the lighting fixtures is maintained until the lighting task ends.

[0057] The lighting area is the ground area within the coverage of the mobile lighting vehicle, divided according to the purpose of the operation. It includes the core operation area, the access protection area, and the edge lighting area. The core operation area is the location where personnel are operating, equipment is being maintained, loading and unloading is being done, hoisting is being done, or continuous construction is being done. The access protection area is the location where personnel, vehicles, or construction machinery can pass through. The edge lighting area is the location outside the core operation area and the access protection area, and only requires auxiliary lighting.

[0058] The method for dividing lighting zones includes: reading the work location, travel route, and lighting coverage boundary in the current lighting task; identifying areas with continuous work activities as core work areas; identifying areas connecting core work areas with external roads, equipment parking locations, or material storage locations as passage guarantee areas; and identifying areas within the lighting coverage boundary other than core work areas and passage guarantee areas as edge lighting areas. When the same location simultaneously meets the definitions of core work areas and passage guarantee areas, that location is identified as a core work area. When the same location simultaneously meets the definitions of passage guarantee areas and edge lighting areas, that location is identified as a passage guarantee area. The core work areas, passage guarantee areas, and edge lighting areas are then written into the vehicle operation observation data as lighting zone types.

[0059] The actual illuminance of each lighting area is collected. The actual illuminance of each lighting area is the illuminance value of the corresponding lighting area after being illuminated within the control cycle. The unit of measurement is lux. Illuminance collection positions are set in each lighting area. The illuminance collection positions are located at the working surface height of the corresponding lighting area. When one illuminance collection position is set in the same lighting area, the illuminance value of the illuminance collection position is taken as the actual illuminance of the corresponding lighting area. When two or more illuminance collection positions are set in the same lighting area, the average value of the illuminance values ​​of the illuminance collection positions in the lighting area is taken as the actual illuminance of the corresponding lighting area.

[0060] In another possible implementation, when two or more illuminance collection points are set up in the core operation area or the passage guarantee area, the minimum value among the illuminance values ​​of each illuminance collection point is taken as the actual illuminance of the corresponding lighting area; when two or more illuminance collection points are set up in the edge lighting area, the average value of the illuminance values ​​of each illuminance collection point is taken as the actual illuminance of the corresponding lighting area.

[0061] The correspondence between lighting fixtures and their respective areas is determined. This correspondence indicates which lighting area each lighting fixture primarily serves. Before the mobile lighting vehicle completes its on-site setup and begins operation, the reference illuminance of each lighting area is collected with all lighting fixtures off. Then, individual lighting fixtures are turned on sequentially while keeping the others off, and the illuminance of each individual lamp in each lighting area is collected. The illuminance increment is obtained by subtracting the reference illuminance from the illuminance of the individual lamp, and the lighting area with the largest illuminance increment is determined as the corresponding lighting area of ​​that lighting fixture.

[0062] When the illuminance increment of two or more lighting areas is the same and is the maximum value, the corresponding lighting areas are determined in descending order of core operation area, passage guarantee area, and edge lighting area, and the lamp number and corresponding lighting area of ​​each lighting fixture are written into the corresponding record of the lamp area.

[0063] In another possible implementation, the correspondence between lighting fixture areas can also be determined based on the installation position, installation height, horizontal orientation, pitch angle, light emission angle, and boundaries of each lighting area of ​​the lighting fixture. First, the illumination coverage area of ​​the lighting fixture on the work surface is determined based on the installation position, horizontal orientation, pitch angle, and light emission angle of the lighting fixture. Then, the overlap area between the illumination coverage area and the core work area, the passage protection area, and the edge lighting area is calculated respectively. The lighting area with the largest overlap area is determined as the corresponding lighting area of ​​the lighting fixture. When the overlap area of ​​two or more lighting areas is the same and both are the maximum value, the corresponding lighting area is determined in descending order of the core work area, the passage protection area, and the edge lighting area. The fixture number and corresponding lighting area of ​​each lighting fixture are written into the lighting fixture area correspondence record.

[0064] The lighting area status results are generated based on the observation data of the lighting vehicle operation. The lighting area status results are used to record the lighting area number, lighting area type, lighting area priority, actual illuminance, target illuminance, minimum illuminance limit and corresponding lighting fixture number of each lighting area, and are used to determine the subsequent illuminance margin, illuminance status and luminaire power reduction control sequence.

[0065] Read the lighting zone types from the light vehicle operation observation data, and determine the lighting zone priority according to the lighting zone type. The core operation zone is determined as the first priority, the traffic guarantee zone is determined as the second priority, and the edge lighting zone is determined as the third priority. The first priority is higher than the second priority, and the second priority is higher than the third priority.

[0066] The target illuminance is the illuminance value that the corresponding lighting area needs to achieve under normal lighting conditions, and the minimum illuminance limit is the illuminance value that the corresponding lighting area still needs to maintain after energy saving and power reduction. The target illuminance is used to determine whether there is an illuminance margin in the lighting area that exceeds normal needs, and the minimum illuminance limit is used to limit the minimum allowable lighting level for subsequent power reduction control.

[0067] The method for setting the target illuminance and the minimum illuminance limit includes: reading the work lighting requirements, on-site safety lighting requirements and historical qualified lighting records corresponding to the current lighting task. The historical qualified lighting records are illuminance records formed by the mobile lighting vehicle in lighting tasks that have been completed and meet the lighting requirements, including lighting area type and corresponding illuminance value. The illuminance values ​​in the historical qualified lighting records are used as qualified illuminance samples, and the qualified illuminance samples are grouped according to the core work area, the passage guarantee area and the edge lighting area.

[0068] Historical qualified lighting records are screened using the following methods:

[0069] Read the operational lighting requirements, on-site safety lighting requirements, illuminance records of each lighting area, and task acceptance results corresponding to the completed lighting task; when the illuminance of each lighting area in the last control cycle before the end of the task is greater than or equal to the corresponding operational lighting requirements and on-site safety lighting requirements, and the task acceptance result is qualified, the illuminance record generated by the lighting task is determined as a historical qualified lighting record; otherwise, the illuminance record is not included in the qualified illuminance sample.

[0070] For qualified illuminance samples corresponding to the same lighting area type, when a qualified illuminance sample exists in the group, the median value of the group's grid illuminance samples is taken as the target illuminance of the sample, and the 15th percentile value of the group's grid illuminance samples is taken as the minimum illuminance of the sample. When there is an illuminance value in the work lighting requirements or on-site safety lighting requirements corresponding to the current lighting task, the illuminance values ​​recorded in the work lighting requirements and on-site safety lighting requirements are read, and the larger value is taken as the task requirement illuminance. When both a qualified illuminance sample and a task requirement illuminance exist in the group, the target illuminance of the sample and the task requirement illuminance are taken as the minimum illuminance. The larger of the required illuminance values ​​is taken as the target illuminance, and the larger of the sample minimum illuminance and the task required illuminance is taken as the minimum illuminance lower limit. When there are qualified illuminance samples in the group but no task required illuminance, the sample target illuminance is taken as the target illuminance, and the sample minimum illuminance is taken as the minimum illuminance lower limit. When there are no qualified illuminance samples in the group but there is task required illuminance, the task required illuminance is taken as both the target illuminance and the minimum illuminance lower limit. When there are no qualified illuminance samples in the group and no task required illuminance, the actual illuminance of the illuminated area is taken as both the target illuminance and the minimum illuminance lower limit.

[0071] In another possible implementation, the target illuminance and the minimum illuminance lower limit can also be determined based on the pre-stored area illuminance configuration in the mobile lighting vehicle controller. The area illuminance configuration includes the lighting area type, the target illuminance configuration value, and the minimum illuminance configuration value. The target illuminance configuration value and the minimum illuminance configuration value corresponding to the current lighting area type are read, and the target illuminance configuration value is used as the target illuminance of the lighting area, and the minimum illuminance configuration value is used as the minimum illuminance lower limit of the lighting area. When the same lighting area type has both area illuminance configuration and task requirement illuminance, the larger value between the target illuminance configuration value and the task requirement illuminance is taken as the target illuminance, and the larger value between the minimum illuminance configuration value and the task requirement illuminance is taken as the minimum illuminance lower limit.

[0072] After initially determining the target illuminance and the minimum illuminance limit, the two are compared. When the target illuminance is less than the minimum illuminance limit, the target illuminance is corrected to the minimum illuminance limit. When the target illuminance is greater than or equal to the minimum illuminance limit, the target illuminance and the minimum illuminance limit remain unchanged, and the target illuminance and the minimum illuminance limit after comparison and verification are written into the corresponding lighting area record.

[0073] Establish a lighting area record for each lighting area. The lighting area record includes the lighting area number, lighting area type, lighting area priority, actual illuminance, target illuminance, minimum illuminance limit, and the lighting fixture number corresponding to that lighting area.

[0074] When the same lighting area corresponds to two or more lighting fixtures, all two or more lighting fixtures are recorded in the lighting fixture number record of the lighting area. When the same lighting fixture corresponds to two or more lighting areas, the corresponding lighting area determined in the corresponding lighting area record is retained as the corresponding area for the lighting fixture to participate in the power reduction order judgment.

[0075] The records of each lighting area are arranged from high to low according to the priority of the lighting area to form the lighting area status results. The lighting area status results are then used for subsequent illuminance margin judgment and determination of the luminaire power reduction control sequence.

[0076] After determining the status of the lighting area, the current output power, remaining lighting hours, and remaining battery power of each lighting fixture are read from the light vehicle's operation observation data. Based on the above data, it is determined whether the mobile light vehicle will run out of power if it continues to operate under the current lighting status until the planned end time of lighting.

[0077] Add up the current output power of each lighting fixture to get the current total power of the fixtures. Multiply the current total power of the fixtures by the remaining lighting hours to get the electricity required for continuous lighting. The electricity required for continuous lighting represents the amount of electricity that the mobile lighting vehicle needs to consume to run until the planned end of lighting without changing the current output power of the lighting fixtures.

[0078] To prevent the energy storage battery from being completely depleted, the battery reserve capacity is subtracted from the remaining battery capacity when calculating the amount of electricity available for lighting control. When the remaining battery capacity is greater than the battery reserve capacity, the difference is taken as the available lighting capacity. When the remaining battery capacity is less than or equal to the battery reserve capacity, the available lighting capacity is set to zero.

[0079] The method for setting the battery reserve capacity includes: reading the minimum safe capacity from the energy storage battery instruction record; reading the historical power consumption records required for the mobile lighting vehicle to perform pole retraction, location warning, and controller standby after the lighting task is completed; when historical power consumption records exist, the sum of the 90th percentile value in the historical power consumption records and the minimum safe capacity is taken as the battery reserve capacity; when no historical power consumption records exist, the sum of the rated power consumption for pole retraction, location warning, and controller standby in the mobile lighting vehicle instruction record and the minimum safe capacity is taken as the battery reserve capacity.

[0080] The power required for continuous lighting is compared with the power available for lighting. When the power required for continuous lighting is greater than the power available for lighting, the difference between the two is determined as the endurance gap, and the endurance status is determined to have an endurance gap.

[0081] When the power required for continuous lighting is less than or equal to the available power for lighting, the power gap is set to zero, and the power status is set to no power gap.

[0082] When there is no remaining power deficit, the mobile lighting vehicle does not need to perform forced power reduction to meet the planned end time of lighting. Instead, it will only include lighting areas where the actual illuminance is greater than the target illuminance in the power reduction judgment.

[0083] When there is a power shortage in the battery life status, the mobile lighting vehicle needs to perform power reduction processing on the premise that the actual illuminance of each lighting area is greater than or equal to the corresponding minimum illuminance limit. Subsequently, based on the illuminance margin and the priority of the lighting area, it is determined which lighting fixtures to reduce the output power first.

[0084] The current total power of the luminaire, the power required for continuous lighting, the available power for lighting, the power gap, the power status, and the remaining lighting hours are written into the power gap result, which can be called when judging the illuminance margin and determining the power reduction control sequence of the luminaire.

[0085] After determining the remaining range deficit, the actual illuminance, target illuminance, and minimum illuminance limit of each lighting area are read from the lighting area status results. The target illuminance margin is determined based on the difference between the actual illuminance and the target illuminance, and the illuminance margin that can be reduced is determined based on the difference between the actual illuminance and the minimum illuminance limit.

[0086] The target illuminance margin is used to indicate whether the corresponding lighting area exceeds the normal lighting requirements. When the actual illuminance is greater than the target illuminance, the difference between the actual illuminance and the target illuminance is determined as the target illuminance margin; when the actual illuminance is less than or equal to the target illuminance, the target illuminance margin is determined as zero.

[0087] The allowable illuminance margin is used to represent the illuminance space that can be reduced in the corresponding lighting area under the premise that it is greater than or equal to the minimum illuminance limit. When the actual illuminance is greater than the minimum illuminance limit, the difference between the actual illuminance and the minimum illuminance limit is determined as the allowable illuminance margin; when the actual illuminance is less than or equal to the minimum illuminance limit, the allowable illuminance margin is determined as zero.

[0088] The illuminance status of each lighting area is determined based on the target illuminance margin and the illuminance margin that can be reduced. When the illuminance margin that can be reduced is zero, the corresponding lighting area is designated as a power reduction prohibited area. When the illuminance margin that can be reduced is greater than zero and the target illuminance margin is zero, the corresponding lighting area is designated as a minimum maintenance area. When the target illuminance margin is greater than zero, the corresponding lighting area is designated as an illuminance redundancy area.

[0089] When there is no remaining range, only the illuminance redundancy area is included in the subsequent power reduction judgment, while the minimum maintenance area and the prohibited power reduction area are not included in the power reduction judgment; when there is a remaining range, the illuminance redundancy area is processed first, then the minimum maintenance area is processed, and the prohibited power reduction area is excluded from the power reduction judgment.

[0090] For each lighting area, the lighting area number, lighting area priority, actual illuminance, target illuminance, minimum illuminance limit, target illuminance margin, illuminance reduction margin, illuminance status, and corresponding lighting fixture number are recorded to form an illuminance margin result, which is then used to determine the luminaire power reduction control sequence.

[0091] After determining the illuminance margin result, read the endurance status and endurance gap in the endurance gap result, and read the lighting area priority, illuminance status, illuminance margin that can be reduced and the corresponding lighting fixture number in the illuminance margin result, in order to determine the lighting fixtures that need to participate in power reduction and their order of priority.

[0092] A power reduction candidate group is established based on the lighting fixture number corresponding to each lighting area. The power reduction candidate group is a set of one or more lighting fixtures corresponding to the same lighting area, and each power reduction candidate group corresponds to a lighting area.

[0093] When the same lighting fixture corresponds to only one lighting area, the lighting fixture is directly written into the power reduction candidate group of the corresponding lighting area; when the same lighting fixture has illuminance increment records for two or more lighting areas, the corresponding lighting area in the corresponding record of the lighting fixture area is used as the area to which the lighting fixture belongs for participating in the power reduction judgment, so as to avoid the same lighting fixture being repeatedly included in multiple power reduction candidate groups.

[0094] When there is no remaining battery life, no forced power reduction is performed. After the power reduction candidate group is established, only the lighting areas with illuminance redundancy are sorted according to the power reduction candidate group.

[0095] When the battery life status indicates a battery life gap, the power reduction candidate group corresponding to the illuminance redundancy area is ranked before the power reduction candidate group corresponding to the minimum maintenance area, and the power reduction prohibited area is excluded from the power reduction judgment.

[0096] When initially screening candidate groups for power reduction, if there is no remaining range, retain candidate groups for power reduction corresponding to the illuminance redundancy area and with a remaining illuminance reduction margin greater than zero, and exclude candidate groups for power reduction corresponding to the minimum maintenance area and the prohibited power reduction area; if there is a remaining range, retain candidate groups for power reduction corresponding to the illuminance redundancy area and the minimum maintenance area and with a remaining illuminance reduction margin greater than zero, and exclude candidate groups for power reduction corresponding to the prohibited power reduction area.

[0097] When sorting the retained power reduction candidate groups, they are first sorted according to the illuminance status, with the power reduction candidate groups corresponding to the illuminance redundancy area ranked before the power reduction candidate groups corresponding to the minimum maintenance area; then they are sorted according to the lighting area priority from low to high, with the power reduction candidate groups corresponding to the edge lighting area ranked before the power reduction candidate groups corresponding to the passage guarantee area, and the power reduction candidate groups corresponding to the passage guarantee area ranked before the power reduction candidate groups corresponding to the core operation area.

[0098] When the illuminance status and lighting area priority of two power reduction candidate groups are the same, they are sorted from largest to smallest according to the illuminance reduction margin; when the illuminance reduction margin is the same, they are sorted from largest to smallest according to the sum of the current output power of the lighting fixtures in the power reduction candidate group; when the above conditions are still the same, they are sorted from smallest to largest according to the smallest fixture number in the power reduction candidate group.

[0099] The power reduction of each power reduction candidate group is determined based on the control boundary illuminance of the lighting area corresponding to the power reduction candidate group and the current output power of the lighting fixtures in the group. The control boundary illuminance is the minimum calculated illuminance that the corresponding lighting area needs to maintain after the power reduction candidate group reduces the power. When the lighting area is an illuminance redundancy area, the target illuminance is used as the control boundary illuminance. When the lighting area is a minimum maintenance area, the minimum illuminance lower limit is used as the control boundary illuminance.

[0100] Specifically, when the actual illuminance of the corresponding lighting area is greater than the control boundary illuminance and the actual illuminance of the corresponding lighting area is greater than zero, the ratio of the difference between the actual illuminance of the corresponding lighting area and the control boundary illuminance to the actual illuminance is first calculated. This ratio is used as the allowable reduction ratio for the lighting area. Then, the allowable reduction ratio is multiplied by the sum of the current output power of the lighting fixtures in the power reduction candidate group to obtain the power that can be reduced for the power reduction candidate group.

[0101] When the actual illuminance of the corresponding lighting area is less than or equal to the control boundary illuminance, or when the actual illuminance of the corresponding lighting area is equal to zero, the power reduction capability of the power reduction candidate group is determined to be zero.

[0102] In another possible implementation, the power reduction capability of each power reduction candidate group can also be determined based on a pre-established dimming level illuminance response relationship. The dimming level illuminance response relationship is formed by collecting illuminance values ​​of the corresponding lighting areas of the power reduction candidate group at different dimming levels after the mobile lighting vehicle completes its on-site setup. When determining the power reduction capability, the dimming levels corresponding to the power reduction candidate group, the power reduction capability corresponding to each dimming level, and the illuminance value of the corresponding lighting area under each dimming level are read. The dimming levels with illuminance values ​​of the corresponding lighting area that are greater than or equal to the control boundary illuminance are taken as available dimming levels. The dimming level with the largest power reduction capability is selected from the available dimming levels, and the power reduction capability corresponding to the dimming level is taken as the power reduction capability of the power reduction candidate group.

[0103] Based on the above sorting results and the power reduction control sequence of the lamps, the product of the power reduction and the remaining lighting hours is used as the corresponding power reduction amount. The power reduction control sequence of the lamps includes the order of the power reduction candidate groups, the corresponding lighting area, the lighting lamp number in the group, the power reduction and the power reduction amount, and serves as the basis for subsequent adjustment of the output power of the lighting lamps.

[0104] After obtaining the power reduction control sequence for the lighting fixtures, the remaining lighting hours, the order of the power reduction candidate groups, the lighting fixture number within the group, and the power that can be reduced are read from the remaining lighting gap result, and used to correct the current output power of the lighting fixtures step by step.

[0105] When there is no remaining range gap, if there is a power reduction candidate group corresponding to the illuminance redundancy area and the power reduction can be greater than zero, then the output power of the corresponding lighting fixtures will be reduced according to the power reduction candidate group corresponding to the illuminance redundancy area, so that the illuminance of the reduced area is greater than or equal to the target illuminance, and the reduced output power of each lighting fixture will be used as the energy-saving output power; if there is no power reduction candidate group corresponding to the illuminance redundancy area and the power reduction can be greater than zero, then the current output power of each lighting fixture will be used as the energy-saving output power.

[0106] When the battery life status is that there is a battery life gap, the battery life gap is determined as the power to be eliminated, and the power reduction candidate group is read in sequence according to the power reduction control sequence of the lamp. The product of the power reduction capacity of the current power reduction candidate group and the remaining lighting hours is the power consumption that the power reduction candidate group can reduce in the corresponding time period of the remaining lighting hours.

[0107] For the currently read power reduction candidate group, if the power consumption that the power reduction candidate group can reduce is less than the power consumption to be eliminated, the actual power reduction of the power reduction candidate group is determined as its power reduction capacity, and the power consumption to be eliminated is updated to the original power consumption to be eliminated minus the power consumption that the power reduction candidate group can reduce.

[0108] For the currently read power reduction candidate group, when the power consumption that the power reduction candidate group can reduce is greater than or equal to the power to be eliminated and the remaining lighting hours are greater than zero, the power value obtained by dividing the power to be eliminated by the remaining lighting hours is determined as the actual power reduction of the power reduction candidate group, and the reading of subsequent power reduction candidate groups is stopped after the power correction of the power reduction candidate group is completed.

[0109] When a candidate group for power reduction includes only one lighting fixture, the actual power reduction of the candidate group is allocated to that lighting fixture. When a candidate group for power reduction includes two or more lighting fixtures, and the sum of the current output power of the candidate group is greater than zero, the actual power reduction is allocated according to the proportion of the current output power of each lighting fixture in the group to the sum of the current output power of the candidate group.

[0110] When the sum of the current output power of the power reduction candidate group is equal to zero, the actual power reduction of the power reduction candidate group is determined to be zero, and the next power reduction candidate group in the lamp power reduction control sequence is read.

[0111] Each lighting fixture is set with a minimum allowable output power, which is the minimum output power required for the lighting fixture to stably light up and maintain normal operation of the driver power supply. When both the lighting fixture driver parameter record and the historical stable lighting record exist, the larger value between the minimum dimming power in the lighting fixture driver parameter record and the minimum output power in the historical stable lighting record that did not experience extinguishing, flickering, or driver power supply failure within one control cycle is taken as the minimum allowable output power. When the historical stable lighting record does not exist, the minimum dimming power in the lighting fixture driver parameter record is taken as the minimum allowable output power.

[0112] When the output power of a lighting fixture after the actual power reduction is less than the minimum allowable output power, the output power of the lighting fixture is adjusted to the minimum allowable output power. The actual power reduction that was not allocated due to the minimum allowable output power limitation is recorded as the remaining power to be allocated, and lighting fixtures that have reached the minimum allowable output power are removed. If there are still lighting fixtures in the same power reduction candidate group that have not reached the minimum allowable output power, the remaining power to be allocated is redistributed according to the ratio of the current output power of the other lighting fixtures to the sum of the current output power of the other lighting fixtures, and the minimum allowable output power verification is performed again until the remaining power to be allocated is zero, or all lighting fixtures in the power reduction candidate group have reached the minimum allowable output power.

[0113] If all lighting fixtures in the same power reduction candidate group have reached the minimum allowable output power but the actual power reduction of that candidate group has not been completed, the power that has not been reduced will be transferred to the next power reduction candidate group in the lighting fixture power reduction control sequence for further processing.

[0114] In another possible implementation, when the same power reduction candidate group includes two or more lighting fixtures, the actual power reduction can be allocated lamp by lamp according to the order of the fixture numbers. First, the actual power reduction of the power reduction candidate group is taken as the power to be allocated. Then, the lighting fixtures in the group are read in ascending order of their numbers. The difference between the current output power and the minimum allowable output power of the currently read lighting fixture is calculated, and this difference is taken as the power reduction that can be allocated to the currently read lighting fixture. When the power reduction that can be allocated to the currently read lighting fixture is less than the power reduction that can be allocated, the output power of the currently read lighting fixture is reduced to the minimum allowable output power, and the power reduction that can be allocated is updated to the original power reduction that can be allocated minus the power reduction that can be allocated to the currently read lighting fixture. When the power reduction that can be allocated to the currently read lighting fixture is greater than or equal to the power reduction that can be allocated, all the power reduction that can be allocated is allocated to the currently read lighting fixture, and the reading of the remaining lighting fixtures in the power reduction candidate group is stopped.

[0115] After each power reduction candidate group is corrected, the updated estimated power consumption is calculated based on the sum of the corrected output power of each lighting fixture and the remaining lighting hours. Then, it is reassessed whether the updated estimated power consumption can be supported by the available lighting power until the planned lighting ends.

[0116] When the updated estimated power consumption is less than or equal to the available lighting power, it is determined that the power deficit has been eliminated, and the current revised output power of each lighting fixture is taken as the energy-saving output power.

[0117] When there are no candidate groups for power reduction that can participate in power reduction, the power required for continuous lighting is used as the updated estimated power consumption. When all candidate groups for power reduction have been processed and the updated estimated power consumption is still greater than the available power for lighting, each lighting fixture is maintained at a state that is greater than or equal to the minimum allowable output power and the corresponding lighting area is greater than or equal to the minimum illuminance limit. The output power of each lighting fixture in this state is used as the minimum energy-saving output power.

[0118] For each power reduction candidate group, the difference between the power that can be reduced in the power reduction candidate group and the power that has actually been reduced in the current control cycle is taken as the remaining power that can be reduced. When the difference is less than zero, the remaining power that can be reduced is determined to be zero, and the product of the remaining power that can be reduced and the remaining lighting hours is taken as the remaining power that can be reduced in the power reduction candidate group.

[0119] The operation of each lighting fixture on the mobile lighting vehicle is controlled according to the energy-saving output power or the guaranteed energy-saving output power. At the next illuminance collection time after the control is completed, the verification illuminance of each lighting area is collected. The verification illuminance is obtained by using the same illuminance collection location, working surface height, illuminance collection equipment and illuminance value summarization method as the actual illuminance before the output power correction, so that the illuminance values ​​before and after the output power correction are comparable. When the output power of the lighting fixtures is restored or compensation reduction is performed because the verification illuminance is lower than the minimum illuminance limit, the verification illuminance of each lighting area is recollected at the next illuminance collection time after the restoration of the lighting fixture output power and compensation reduction are completed. The recollected verification illuminance is used as the new verification illuminance to continue the verification illuminance judgment, and the verification illuminance collected last before the end of the control cycle is written into the energy-saving control result of the lighting vehicle.

[0120] See Figure 4 As shown, when the verified illuminance of the core work area, passage guarantee area and edge lighting area collected after output power correction is greater than or equal to the corresponding minimum illuminance lower limit, output power recovery and compensation reduction will no longer be performed; at the same power collection time, the remaining battery power after output power correction is higher than the remaining battery power before output power correction, and is still higher than the battery reserve power at the end of the planned lighting, thereby reducing lighting power consumption while meeting the minimum illuminance requirements of each lighting area.

[0121] When the verification illuminance of two or more lighting areas is less than their respective minimum illuminance limits, the output power is restored sequentially according to the priority of the lighting areas from high to low. The lighting areas with verification illuminance less than the corresponding minimum illuminance limits are corresponding to the power reduction candidate group and do not participate in this round of compensation reduction processing. After each output power restoration and compensation reduction is completed, the verification illuminance of each lighting area is re-collected, and the next processing area is determined based on the re-collected verification illuminance.

[0122] When the verified illuminance of the core operating area is less than the minimum illuminance limit of the core operating area, the output power of the corresponding lighting fixtures in the core operating area is restored to the level before the correction in this control cycle. The difference between the restored output power and the original output power of the corresponding lighting fixtures in the core operating area is taken as the restored power increase. The product of the restored power increase and the remaining lighting hours is taken as the amount of electricity to be compensated. Then, according to the lighting fixture power reduction control sequence, candidate groups for power reduction that have a lower priority than the core operating area, a verified illuminance greater than or equal to the corresponding minimum illuminance limit, and a remaining power reduction capacity greater than zero are read sequentially. When the remaining power reduction capacity of the currently read power reduction candidate group is less than the amount of electricity to be compensated, the remaining power reduction capacity of the power reduction candidate group is... As compensation for power reduction; when the remaining reduceable power of the currently read power reduction candidate group is greater than or equal to the power to be compensated and the remaining lighting hours are greater than zero, the power value obtained by dividing the power to be compensated by the remaining lighting hours is used as the compensation power reduction; after completing the compensation power reduction allocation of the current power reduction candidate group and updating the power to be compensated, if the power to be compensated is zero, then stop reading the subsequent power reduction candidate group; if the power to be compensated is still greater than zero, then continue reading the next qualified power reduction candidate group; when all power reduction candidate groups with lighting area priority lower than core work area, verified illuminance greater than or equal to the corresponding minimum illuminance lower limit, and remaining reduceable power greater than zero have been read and the power to be compensated is still greater than zero, then the compensation reduction process stops.

[0123] When the verified illuminance of the passage protection zone is less than the minimum illuminance limit of the passage protection zone, the output power of the corresponding lighting fixtures in the passage protection zone is restored to the level before the correction in this control cycle. The difference between the restored output power and the original output power of the corresponding lighting fixtures in the passage protection zone is taken as the restored power increase. The product of the restored power increase and the remaining lighting hours is taken as the amount of electricity to be compensated. Then, according to the lighting fixture power reduction control sequence, candidate groups for power reduction are read sequentially, provided that the lighting area priority is lower than the passage protection zone, the verified illuminance is greater than or equal to the corresponding minimum illuminance limit, and the remaining power that can be reduced is greater than zero. When the remaining power that can be reduced in the currently read power reduction candidate group is less than the amount of electricity to be compensated, the remaining power that can be reduced in the power reduction candidate group is... As compensation for power reduction; when the remaining reduceable power of the currently read power reduction candidate group is greater than or equal to the power to be compensated and the remaining lighting hours are greater than zero, the power value obtained by dividing the power to be compensated by the remaining lighting hours is used as the compensation power reduction; after completing the compensation power reduction allocation of the current power reduction candidate group and updating the power to be compensated, if the power to be compensated is zero, then stop reading the subsequent power reduction candidate group; if the power to be compensated is still greater than zero, then continue reading the next qualified power reduction candidate group; when all power reduction candidate groups with lighting area priority lower than the passage guarantee area, verified illuminance greater than or equal to the corresponding minimum illuminance lower limit, and remaining reduceable power greater than zero have been read and the power to be compensated is still greater than zero, then the compensation reduction process is stopped.

[0124] The compensated power reduction is allocated to the corresponding lighting fixtures according to the allocation rules within the same power reduction candidate group, and is subject to the minimum allowable output power limit. When the actual power reduction is implemented by allocating the power reduction to each fixture sequentially according to the fixture number, the compensated power reduction is allocated to the corresponding lighting fixtures according to the same fixture allocation rule. The sum of the actual power reduction of each lighting fixture in the corresponding power reduction candidate group in this compensation is taken as the actual completed compensated power reduction. The product of the actual completed compensated power reduction and the remaining lighting hours is taken as the actual compensated electricity. The electricity to be compensated is updated to the original electricity to be compensated minus the actual compensated electricity. When the updated electricity to be compensated is less than zero, the electricity to be compensated is set to zero, and the remaining reduceable power and remaining reduceable electricity of the corresponding power reduction candidate group are recalculated based on the actual completed compensated power reduction. When the minimum allowable output power limit causes the compensated power reduction to be incompletely allocated and the electricity to be compensated is still greater than zero, the unallocated compensated power reduction is transferred to the subsequent power reduction candidate group defined by the corresponding review illuminance processing segment for further processing.

[0125] When the verification illuminance of the edge lighting area is less than the minimum illuminance limit of the edge lighting area, and both the core operation area and the passage protection area have reached the corresponding minimum illuminance limit, maintain the output power of the corresponding lighting fixtures in the core operation area and the passage protection area, and restore the output power of the corresponding lighting fixtures in the edge lighting area to the level before the correction in this control cycle, so that the verification illuminance of the edge lighting area is greater than or equal to the minimum illuminance limit.

[0126] At the end of the control cycle, the output power of each lighting fixture at the end of this control cycle is taken as the final output power. The sum of the final output power of each lighting fixture is multiplied by the remaining lighting hours to obtain the final estimated power consumption. When the final estimated power consumption is less than or equal to the available lighting power, the endurance gap elimination status is recorded as eliminated. When the final estimated power consumption is greater than the available lighting power, the endurance gap elimination status is recorded as not eliminated. The final output power of each lighting fixture, the verification illuminance of each lighting area, and the endurance gap elimination status are written into the lighting vehicle energy-saving control results. The lighting vehicle operation observation data are collected again in the next control cycle.

[0131] The battery life determination module is used to determine the power required for continuous lighting and the available power for lighting based on the current output power of each lighting fixture, the remaining lighting time, and the remaining battery power. Based on the comparison between the power required for continuous lighting and the available power for lighting, it generates a battery life gap result that includes the battery life status and the battery life gap.

[0132] The power reduction decision module is used to determine the illuminance margin and illuminance status based on the actual illuminance, target illuminance, minimum illuminance limit and lighting area priority in the lighting area status results, and to determine the illuminance power reduction control sequence by combining the endurance gap results and the correspondence between the luminaire area and the lighting area.

[0133] The correction and verification module is used to correct the output power of each lighting fixture according to the lighting fixture power reduction control sequence. After the output power is corrected, the verification illuminance of each lighting area is collected. Based on the verification illuminance, the output power is restored and compensated for reduction, and the energy-saving control result of the lighting vehicle is generated.
