Description

Technical Field

[0001] This invention relates to the field of parking space management technology, and in particular to a parking lot parking space management and lighting system. Background Technology

[0002] With the continuous growth of urban motor vehicle ownership, the demand for parking resources in commercial complexes, hospitals, transportation hubs, and residential communities has increased dramatically. Due to land resource constraints, underground and multi-story parking garages have become the main construction methods. However, in actual operation, the enclosed interior space, complex passageways, and limited lighting conditions of parking lots, coupled with the lack of an effective intelligent management system, can easily lead to problems such as long search times for parking spaces, congestion, and high management costs, seriously affecting parking efficiency and user experience.

[0003] Currently, traditional parking lot management relies heavily on manual inspections or simple geomagnetic detection technology. Manual inspections suffer from drawbacks such as high labor costs, poor real-time performance, and high error rates, making it difficult to achieve dynamic monitoring and data statistics. While single-sensor detection methods can identify parking space occupancy status, they are typically only used for backend statistics or summary displays at the entrance, lacking intuitive indication of the status of individual parking spaces. Drivers still need to repeatedly search for vacant spaces within the lot, reducing traffic efficiency.

[0004] On the other hand, most parking lot lighting systems adopt a constant-on design to meet safety lighting requirements. However, this approach ignores the dynamic changes in vehicle and pedestrian flow, maintaining high brightness during off-peak hours or in areas without vehicles, leading to energy waste and increased operating costs. Furthermore, existing parking guidance systems and lighting systems are mostly designed independently, lacking a unified control and data linkage mechanism. This prevents them from adaptively adjusting based on parking space occupancy, pedestrian activity, or ambient light intensity, hindering the synergistic optimization of energy conservation and intelligent management.

[0005] In recent years, while there have been attempts to combine parking guidance systems with smart lighting technology—for example, using traffic lights to indicate parking space status or using sensor-activated lights for area lighting control—most systems remain at the level of functional overlay. They haven't formed a unified management architecture centered on parking space status data, failing to achieve deep integration of parking information collection, status indication, route guidance, and on-demand lighting control. Furthermore, the lack of centralized management and analysis of parking space usage data hinders the optimal allocation and refined operation of parking resources.

[0006] In summary, the existing technology has at least the following technical problems: Existing parking systems suffer from technical problems such as low efficiency in parking space status recognition and guidance, inability to adjust lighting as needed, and fragmented management systems, resulting in both low parking efficiency and energy waste. Summary of the Invention

[0007] The purpose of this invention is to provide a parking space management and lighting system to solve the technical problems of low efficiency in parking space status recognition and guidance, inability to adjust lighting as needed, and fragmented management systems in existing parking systems, which result in both low parking efficiency and energy waste.

[0008] The preferred technical solutions among the many technical solutions provided by this invention can produce a variety of technical effects, which are described in detail below.

[0009] To address the aforementioned technical problems, the present invention provides the following technical solution: This invention provides a parking lot management and lighting system, including multiple intelligent parking space lights arranged above the lanes and each corresponding to at least one parking space; at least one area node controller communicating with the multiple intelligent parking space lights in the same area; a central controller communicating with the multiple area node controllers; and a guidance display terminal communicating with the central controller and / or the area node controllers. Each intelligent parking space light includes: a parking space detection unit, a lighting source and lighting drive unit, a parking space status indicator unit, a wireless communication unit, and a light control unit. The light control unit generates a parking space occupancy status based on the parking space detection data output by the parking space detection unit and controls the parking space status indicator unit to display the occupancy or vacancy status, while simultaneously reporting the parking space status information to the area node controller. The area node controller summarizes the parking space status information and reports it to the central controller. The central controller outputs overall or zoned vacancy information to the guidance display terminal to achieve coordinated management of parking guidance and lighting.

[0010] In one embodiment, the intelligent parking space lighting fixture further includes a motion detection unit. When the motion detection unit detects an activity event of a vehicle and / or a person, the lighting control unit receives the motion detection data and controls the lighting drive unit to adjust the lighting source to a high-brightness working state. When no activity is detected, the lighting drive unit controls the lighting source to adjust to an energy-saving working state.

[0011] In one embodiment, the parking space detection unit includes at least one of ultrasonic detection, geomagnetic detection, millimeter wave detection, and video detection, and the lighting control unit determines the parking space occupancy status based on the detection results of the parking space detection unit; when the parking space detection unit includes at least two detection methods, the lighting control unit determines the parking space occupancy status based on the fusion of multi-source detection results.

[0012] In one embodiment, the parking space status indicator unit includes at least two distinguishable indicator states, which respectively indicate that the parking space is vacant and the parking space is occupied, and the indicator states are updated synchronously with the parking space occupancy status.

[0013] In one embodiment, the lighting control unit adopts a stable determination mechanism for updating the parking space occupancy status; the stable determination mechanism includes: performing statistical or filtering processing on the parking space detection data within a preset sliding time window, and forming a current determination value based on the processing result; only when the current determination value meets the consistency condition in multiple consecutive samplings is it confirmed that the parking space occupancy status has switched.

[0014] In one implementation, the consistency condition includes one or a combination of the following: a) The judgment results of multiple consecutive samplings are consistent; b) The same direction determination is satisfied within the preset number of sampling times; c) Use hysteresis thresholds or upper and lower thresholds to suppress “idle / occupied” switching in order to reduce jitter misjudgment.

[0015] In one embodiment, the lighting control unit further outputs a detection reliability index associated with the parking space occupancy status based on the fluctuation characteristics and / or consistency results of the parking space detection data; when the reliability is lower than a preset condition and / or the parking space occupancy status changes abnormally within a preset time, the lighting control unit marks the parking space status as abnormal and reports it, and controls the parking space status indicator unit to output an abnormal prompt status that is different from vacant / occupied.

[0016] In one embodiment, after receiving an abnormal status report, the regional node controller and / or the central controller issue a self-test or calibration command to the corresponding smart parking space light fixture; the self-test or calibration includes one or a combination of the following: sensor channel status detection, detection baseline update, detection threshold adaptive correction, fault isolation or abnormal parking space shielding strategy issuance.

[0017] In one embodiment, the central controller and / or the regional node controller generate a linkage lighting strategy based on vehicle and / or personnel activity events reported by the smart parking space lights. The linkage lighting strategy is used to keep several adjacent smart parking space lights related to the location of the activity event in a high-brightness working state within a preset time window when the activity event is detected, thereby improving lane visibility and parking efficiency while satisfying energy saving.

[0018] In one embodiment, the parking space management and lighting system adopts a hierarchical communication architecture: the intelligent parking space lights and the area node controllers use short-range wireless communication, and the area node controllers and the central controllers use long-range wireless or wired communication; and the parking space status information includes at least the light fixture identifier, parking space identifier, occupied or vacant status, and time information, and the central controller performs statistics on the parking space status information to generate the number of vacant spaces in each zone and / or the total number of vacant spaces in the entire parking lot.

[0019] The beneficial effects of this invention are as follows: (1) Improve the efficiency of parking space status recognition and guidance Each smart parking space light corresponds to at least one parking space and independently collects parking space detection data, generates parking space occupancy status in real time, and displays it directly through the parking space status indicator unit. Drivers can quickly identify vacant parking spaces by color or indicator status. At the same time, the area node controller and the central controller summarize and statistically analyze the parking space status information and output the number of vacant spaces in the zone or the whole area on the guidance display terminal, improving the efficiency of finding parking spaces from both local indication and global guidance levels, and reducing unnecessary detours within the parking lot.

[0020] (2) Achieve integrated linkage between parking space management and lighting control In traditional systems, parking guidance and lighting systems are usually set up independently. This technical solution integrates parking space detection and lighting drive into the same device through a lamp control unit, so that the parking space status and lighting status form a basis for linkage management. At the system level, the central controller can uniformly schedule and realize the coordinated control of parking space information and lighting strategy, avoid the fragmented operation of the system, and improve the overall management efficiency.

[0021] (3) Reduce energy consumption and improve energy efficiency By implementing intelligent control at the lighting level of smart parking space lights, and combining a hierarchical management architecture of regional node control and central control, lighting strategies can be adjusted according to the parking space status and the operation of the parking lot. This avoids the energy waste caused by traditional constant lighting, achieves on-demand lighting and energy-saving operation, and reduces parking lot operating costs.

[0022] (4) Improve system scalability and maintenance convenience The system adopts a hierarchical communication architecture, with intelligent parking space lights serving as the basic data acquisition and execution units, regional node controllers responsible for regional data aggregation, and a central controller responsible for global management, enabling the system to have modular expansion capabilities. When the parking lot expands or the area is adjusted, only the corresponding lights or node controllers need to be added, which facilitates deployment and upgrades.

[0023] (5) Improve the overall reliability and management visualization level of the system. By centrally collecting and uniformly outputting parking space status information, real-time monitoring and data-driven management of parking resources can be achieved, providing a foundation for subsequent data analysis, operation optimization, and remote management, and improving the level of intelligent and refined management of parking lots.

[0024] In summary, this technical solution not only solves the problems of low parking space recognition efficiency and fragmented management system in existing parking lots, but also realizes integrated management of parking space guidance and lighting control. It effectively reduces energy consumption while improving parking efficiency, and has significant technological advancement and practical application value. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] This specific implementation provides a parking space management and lighting system, which includes multiple intelligent parking space lights, area node controllers, a central controller, and a guidance display terminal. The intelligent parking space lights are arranged above the lanes and correspond to at least one parking space. Each light includes a parking space detection unit, a lighting source and lighting drive unit, a parking space status indicator unit, a wireless communication unit, and a light control unit. The light control unit generates the parking space occupancy status based on the parking space detection data and controls the parking space status indicator unit to display the occupancy or vacancy status, while simultaneously reporting the parking space status information to the area node controller. The area node controller summarizes the information and uploads it to the central controller, which then outputs vacancy information for a specific area or the entire parking lot to the guidance display terminal. The system achieves integrated management of parking space detection, status indication, guidance dissemination, and lighting control, improving parking space identification and guidance efficiency and reducing lighting energy consumption. It effectively solves the technical problems of existing parking lot systems, such as low efficiency in parking space status identification and guidance, inability to adjust lighting on demand, and fragmented management systems, leading to both low parking efficiency and energy waste.

[0030] The first implementation of a parking space management and lighting system, for example Figure 1 As shown, the system includes multiple intelligent parking space lights 1, arranged above the lane and corresponding to at least one parking space; at least one area node controller 2, communicating with the multiple intelligent parking space lights 1 in the same area; a central controller 3, communicating with the multiple area node controllers 2; and a guidance display terminal 4, communicating with the central controller 3 and / or the area node controllers 2. Each intelligent parking space light 1 includes: a parking space detection unit 11, a lighting source 121 and a lighting drive unit 12, a parking space status indicator unit 13, a wireless communication unit 14, and a light control unit 15. The light control unit 15 generates the parking space occupancy status based on the parking space detection data output by the parking space detection unit 11, and controls the parking space status indicator unit 13 to display the occupancy or vacancy status, while reporting the parking space status information to the area node controllers 2. The area node controllers 2 summarize the parking space status information and report it to the central controller 3. The central controller 3 outputs the overall or zoned vacancy information to the guidance display terminal 4 to realize the linkage management of parking space guidance and lighting.

[0031] The parking space management and lighting system provided by this technical solution integrates parking space detection, status indication, lighting adjustment, and data reporting functions into the intelligent parking space light fixture 1, and constructs a hierarchical management architecture of "light fixture - area node controller 2 - central controller 3 - guidance display terminal 4". This achieves unified management of parking space information collection, status display, data aggregation, and guidance release. Compared with existing technologies, it has at least the following technical effects: improved efficiency of parking space status recognition and guidance; each intelligent parking space light fixture 1 corresponds to at least one parking space and independently collects parking space detection data, generates parking space occupancy status in real time, and directly displays it through the parking space status indication unit 13. Drivers can quickly identify vacant parking spaces through color or indication status; at the same time, the area node controller 2 and the central controller 3 summarize and statistically analyze the parking space status information and output the number of vacant spaces in the zone or the whole parking lot on the guidance display terminal 4, improving the efficiency of finding parking spaces from both local indication and global guidance levels, and reducing unnecessary detours within the parking lot.

[0032] This solution achieves integrated linkage between parking space management and lighting control. In traditional systems, parking guidance and lighting systems are usually set up independently. This technical solution integrates parking space detection and lighting drive into the same device through the lighting control unit 15, so that the parking space status and lighting status form a basis for linkage management. At the system level, the central controller 3 coordinates the scheduling to achieve coordinated control of parking space information and lighting strategy, avoids the fragmented operation of the system, and improves the overall management efficiency.

[0033] Reduce energy consumption and improve energy efficiency; by implementing intelligent control at the lighting level of the intelligent parking space lighting fixture 1, and combining a hierarchical management architecture of regional node control and central control, the lighting strategy is adjusted according to the parking space status and the operation of the parking lot, thereby avoiding the energy waste caused by traditional constant lighting, realizing on-demand lighting and energy-saving operation, and reducing the operating cost of the parking lot.

[0034] Improve system scalability and maintenance convenience; adopt a layered communication architecture, with intelligent parking space lights 1 as the basic data acquisition and execution unit, regional node controllers 2 responsible for regional data aggregation, and central controllers 3 responsible for global management, enabling the system to have modular expansion capabilities; when the parking lot scale expands or the area is adjusted, only the corresponding lights or node controllers need to be added, which is convenient for deployment and upgrades.

[0035] Improve the overall reliability and management visualization of the system; by centrally collecting and uniformly outputting parking space status information, realize real-time monitoring and data-driven management of parking resources, provide a foundation for subsequent data analysis, operation optimization and remote management, and improve the intelligent and refined management level of parking lots.

[0036] In summary, this technical solution not only solves the problems of low parking space recognition efficiency and fragmented management system in existing parking lots, but also realizes integrated management of parking space guidance and lighting control. It effectively reduces energy consumption while improving parking efficiency, and has significant technological advancement and practical application value.

[0037] As one alternative implementation method: Regarding the motion detection of moving objects within the parking lot using the aforementioned intelligent parking space lighting fixture 1, this implementation is, for example... Figure 2 As shown, the intelligent parking space lighting fixture 1 also includes a motion detection unit 16. When the motion detection unit 16 detects an activity event of a vehicle and / or a person, the lighting control unit 15 receives the motion detection data and controls the lighting drive unit 12 to adjust the lighting source 121 to enter a high-brightness working state. When no activity is detected, the lighting drive unit 12 controls the lighting source 121 to enter an energy-saving working state.

[0038] In application, after the intelligent parking space light fixture 1 is installed above the lane, the motion detection unit 16 continuously detects the activities of vehicles and / or pedestrians within the lane area in real time. The light fixture control unit 15 receives the motion detection data and judges its validity. When an activity event is detected, the light fixture control unit 15 immediately outputs a high-brightness control command to the lighting drive unit 12, causing the lighting source 121 to enter a high-brightness working state. When no activity event is detected within a preset time, the light fixture control unit 15 outputs an energy-saving control command to the lighting drive unit 12, causing the lighting source 121 to enter an energy-saving working state. By integrating motion detection and lighting drive into the same light fixture, local real-time response is achieved, and instant lighting adjustment can be completed without central unified scheduling. At the same time, motion detection data can also serve as the basic data source for subsequent linkage lighting strategies, forming a collaborative control link with the area node controller 2 and the central controller 3. This structure effectively solves the problem of energy waste caused by the constant illumination of traditional parking lot lighting, and ensures sufficient lane lighting when there are vehicles or pedestrians passing by, improving safety and user experience.

[0039] The motion detection unit 16 can use microwave radar, infrared PIR, or a combination of both to adapt to different environments; the high-brightness and energy-saving working states of the illumination source 121 can correspond to different brightness percentage ranges; in the energy-saving state, the minimum safe illuminance is set to meet the monitoring camera requirements; the delay parameter can be remotely configured by the central controller 3 to adapt to different time periods or different traffic densities.

[0040] In one embodiment, the lighting control unit 15 performs edge triggering and duration judgment on the motion detection signal, and determines a valid trigger only when the activity lasts for more than a first threshold time t1; when the continuous inactivity time exceeds a second threshold time t2, the energy-saving mode is restored. This dual-threshold control strategy can avoid false triggering and reduce frequent dimming caused by short-term interference.

[0041] Regarding the detection of parking spaces by the aforementioned parking space detection unit 11, this implementation is as follows: Figure 2 As shown, the parking space detection unit 11 includes at least one of ultrasonic detection, geomagnetic detection, millimeter wave detection, and video detection. The lighting control unit 15 determines the parking space occupancy status based on the detection results of the parking space detection unit 11. When the parking space detection unit 11 includes at least two detection methods, the lighting control unit 15 determines the parking space occupancy status based on the fusion of multi-source detection results.

[0042] In application, the parking space detection unit 11 continuously outputs parking space detection data, and the lighting control unit 15 parses the detection data and generates the parking space occupancy status. When using a single detection method, occupancy or vacancy is determined based on a detection threshold; when using two or more detection methods, the lighting control unit 15 fuses the multi-source detection results to improve accuracy. The occupancy status is used to control the display on the parking space status indicator unit 13, and is also uploaded to the area node controller 2 via the wireless communication unit 14, achieving coordination between local detection and global statistics. This structure avoids the high misjudgment rate problem of traditional manual inspection and improves the real-time performance of detection through distributed acquisition.

[0043] Multi-source fusion can employ weighted voting mechanisms, priority mechanisms, or confidence-weighted mechanisms; different detection methods can be combined for different scenarios, such as using ultrasound + millimeter wave in underground parking garages and geomagnetism + video in surface parking lots; detection sensitivity and thresholds can be configured remotely.

[0044] In one embodiment, when using both ultrasonic and geomagnetic detection methods, the lighting control unit 15 executes the following logic: if both ultrasonic and geomagnetic detections indicate "occupancy," then the system is determined to be occupied; if the two results are inconsistent, a fusion determination is made based on historical stable states and weighting coefficients. This fusion mechanism can significantly reduce misjudgments caused by errors from a single sensor.

[0045] Regarding the indication mechanism of the aforementioned parking space status indication unit 13, this implementation is as follows: Figure 2 As shown, the parking space status indicator unit 13 includes at least two distinguishable indicator states, which are used to indicate whether the parking space is vacant or occupied, and the indicator states and the parking space occupancy status are updated synchronously.

[0046] In application, once the lighting control unit 15 generates a parking space occupancy status, it immediately controls the parking space status indicator unit 13 to update the indicator status, synchronizing the indicator status with the parking space occupancy status. This synchronization update mechanism, together with the parking space detection unit 11 and the data upload mechanism, forms a closed loop, ensuring that local visual prompts are consistent with central statistical data, avoiding the management fragmentation problem of "inconsistency between on-site display and screen display." Drivers can directly determine the availability of parking spaces through the lights, without relying on a remote display screen to search area by area, improving parking space search efficiency.

[0047] The parking space status indicator unit 13 can use red and green dual-color LEDs, a ring light strip, or a top light-emitting module; in abnormal conditions, it can use flashing or different colors to indicate; the indicator brightness can be linked with the lighting brightness or adjusted independently.

[0048] The parking space status indicator unit 13 and the lighting control unit 15 are powered by the same control board or the same power module, which reduces system complexity and improves reliability.

[0049] The second embodiment of the parking space management and lighting system differs from the first embodiment in that the lighting control unit 15 adopts a stable determination mechanism for updating the parking space occupancy status. The stable determination mechanism includes: performing statistical or filtering processing on the parking space detection data within a preset sliding time window, and forming a current determination value based on the processing result; only when the current determination value meets the consistency condition in multiple consecutive samplings is it confirmed that the parking space occupancy status has changed.

[0050] Consistency conditions include one or a combination of the following: a) Consistent judgment results from multiple consecutive samplings; b) Satisfying the same direction judgment a preset number of times within a preset number of samplings; c) Using hysteresis thresholds or upper and lower thresholds to suppress “idle / occupied” switching in order to reduce jitter misjudgment.

[0051] In practical applications, parking space detection data may fluctuate due to environmental interference. The lighting control unit 15 performs statistical or filtering processing on the detection data within a preset sliding time window to generate a current judgment value; the parking space status switch is only confirmed when this judgment value meets the consistency condition across multiple consecutive samples. This stable judgment mechanism, working in conjunction with the multi-source detection mechanism, effectively avoids erroneous switching caused by short vehicle stops, pedestrian obstruction, or environmental noise. This structure improves system reliability at the algorithm level and solves the problem of confusing indications caused by frequent jumps in traditional detection systems.

[0052] The preset sliding time window length can be adaptively adjusted according to traffic density; the consistency condition can adopt a proportional threshold mechanism or a hysteresis double threshold mechanism; the judgment sensitivity for different time periods can be set.

[0053] For example, in a sliding window with a sliding time window length of N, a switch is confirmed only when the judgments are consistent for K consecutive times (K≥N×α, where α is a proportional coefficient); or a dual threshold mechanism is adopted: the occupancy judgment threshold is higher than the idle judgment threshold, forming a hysteresis interval.

[0054] The third embodiment of the parking space management and lighting system differs from the first embodiment in that the lighting control unit 15 also outputs a detection reliability index associated with the parking space occupancy status based on the fluctuation characteristics and / or consistency results of the parking space detection data; when the reliability is lower than the preset condition and / or the parking space occupancy status changes abnormally within a preset time, the lighting control unit 15 marks the parking space status as abnormal and reports it, and controls the parking space status indicator unit 13 to output an abnormal prompt status that is different from vacant / occupied.

[0055] After receiving an abnormal status report, the area node controller 2 and / or the central controller 3 send a self-test or calibration command to the corresponding smart parking space light fixture 1. The self-test or calibration includes one or a combination of the following: sensor channel status detection, detection baseline update, detection threshold adaptive correction, fault isolation or abnormal parking space shielding strategy issuance.

[0056] In application, the lighting control unit 15 generates a detection reliability index based on the fluctuation characteristics or consistency results of parking space detection data. When the reliability falls below a preset condition or an abnormal change occurs in the parking space status, the system marks the parking space status as abnormal and reports it, while the indicator unit outputs an abnormal status message. After receiving the abnormal report, the area node controller 2 or the central controller 3 issues a self-test or calibration command. Through a closed-loop mechanism of "detection—evaluation—abnormal marking—remote intervention," the system achieves self-monitoring and self-recovery capabilities, significantly improving system reliability and avoiding statistical distortion of parking spaces caused by long-term misjudgments.

[0057] Abnormal conditions can trigger maintenance notifications; abnormal parking spaces can be temporarily removed from statistics; the system can automatically perform baseline updates during low traffic hours at night.

[0058] The reliability C can be calculated from the standard deviation of parking space detection data, the number of historical stable times, or the sensor signal-to-noise ratio; when C is below the threshold, an anomaly is triggered; the central controller 3 records the frequency of anomalies for predictive maintenance.

[0059] The fourth embodiment of the parking space management and lighting system differs from the first embodiment in that the central controller 3 and / or the area node controller 2 generate a linkage lighting strategy based on the activity events of vehicles and / or people reported by the intelligent parking space lights 1. The linkage lighting strategy is used to keep several adjacent preset intelligent parking space lights 1 related to the location of the activity event in a high-brightness working state within a preset time window when an activity event is detected, thereby improving lane visibility and parking space search efficiency while meeting energy saving requirements.

[0060] The parking space management and lighting system adopts a hierarchical communication architecture: the intelligent parking space light fixture 1 and the area node controller 2 use short-range wireless communication, and the area node controller 2 and the central controller 3 use long-range wireless communication or wired communication; and the parking space status information includes at least the light fixture identification, parking space identification, occupancy status or vacancy status and time information. The central controller 3 counts the parking space status information to generate the number of vacant spaces in the zone and / or the total number of vacant spaces in the entire parking lot.

[0061] In application, the central controller 3 or the regional node controller 2 generates a coordinated lighting strategy based on the activity events reported by the intelligent parking space lights 1. When an activity event occurs at a certain location, a preset number of adjacent lights related to that location remain in a high-brightness state within a preset time window, forming a "light strip lighting path." This strategy works in conjunction with a hierarchical communication architecture, enabling the intelligent parking space lights layer 1 to achieve rapid response, and the node layer and the central layer to coordinate strategies, thereby balancing energy saving and driving safety. This mechanism solves the problem of waste caused by the isolated operation of traditional local lighting and constant illumination throughout the entire area.

[0062] The number of adjacent smart parking space lights can be set according to the lane length; the preset time window can be dynamically adjusted according to the vehicle speed estimate; the direction of travel can be inferred according to the continuous triggering sequence.

[0063] The central controller 3 records the continuous lighting triggering sequence. When the triggering sequence extends in one direction, it determines the direction of vehicle travel and lights up several lights in front in advance.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

The parking space management and lighting system according to claim 1, characterized in that, The central controller and / or the regional node controller generate a linkage lighting strategy based on the activity events of vehicles and / or people reported by the intelligent parking space lights. The linkage lighting strategy is used to keep several adjacent preset intelligent parking space lights related to the location of the activity event in a high-brightness working state within a preset time window when the activity event is detected, thereby improving lane visibility and parking efficiency while satisfying energy saving.

10. The parking space management and lighting system according to claim 1, characterized in that, The parking space management and lighting system adopts a hierarchical communication architecture: the intelligent parking space lights and the area node controllers use short-range wireless communication, and the area node controllers and the central controllers use long-range wireless or wired communication; and the parking space status information includes at least the light fixture identifier, parking space identifier, occupied or vacant status, and time information. The central controller counts the parking space status information to generate the number of vacant spaces in each zone and / or the total number of vacant spaces in the entire parking lot.
