[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The present application embodiment discloses a smart park management system, such as Figure 1 As shown, it includes intelligent security system, intelligent transportation system, intelligent building management system, intelligent environmental monitoring system, intelligent energy management system, communication system and monitoring center.

[0042] For example, the intelligent security system uses surveillance cameras, access control systems including but not limited to fingerprint locks, password locks, and facial recognition locks with biometric technology, perimeter electronic fences, electronic patrol systems and other technical means to monitor the security status of the park in real time. Security personnel can detect abnormal situations in time and take corresponding measures to efficiently ensure the safety of the park. The intelligent transportation system uses technologies such as the Internet of Things and communications to achieve intelligent management of vehicle traffic entering the park. The intelligent transportation system mainly includes intelligent traffic sensors, vehicle identification systems, video monitoring systems, information display devices, and parking guidance systems. Among them, intelligent traffic sensors can obtain and analyze traffic flow by sensing information such as vehicles and pedestrians in the surrounding environment. The vehicle identification system uses high-definition cameras, license plate readers, vehicle barriers and other equipment to realize the identification and collection of vehicle information and vehicle entry and exit, and charges through electronic payment. The video monitoring system uses cameras installed on the roads in the park to perform image processing and analysis through big data technology to monitor and manage traffic conditions. Information display equipment includes LED street lights and road information display boards / display screens, etc., which provide convenience for driving vehicles; the parking guidance system detects the use of each parking space in real time by setting a detector in each parking space, and then informs the driver in advance of the use of parking spaces in a certain parking area through the parking space display screen. The intelligent building management system uses intelligent equipment and sensors to achieve centralized management of various buildings in the park, including fire alarm systems, intelligent lighting systems, air conditioning systems, etc. Among them, the fire alarm system uses smoke sensors to monitor whether there is smoke in the building to prevent fires. The intelligent lighting system is equipped with light sensors to monitor the light intensity inside and outside the building, and can automatically adjust the lighting brightness according to the light intensity or personnel needs to improve energy efficiency. The air conditioning system controls the temperature, humidity, air flow speed, etc. in the building through temperature and humidity sensors and air conditioning controllers to achieve a comfortable indoor environment. The intelligent environmental monitoring system uses various sensors and monitoring equipment to monitor the environmental parameters in the park in real time, such as temperature, noise level, humidity, air quality, etc., to detect environmental problems in time and transmit communications to the monitoring center, so that the monitoring management personnel can take corresponding measures to improve the environmental quality of the park. The communication system is used to connect various devices to the same network to achieve linkage and interconnection, including but not limited to network devices such as routers, switches, bridges, gateways, etc. for data transmission and management, as well as wireless devices such as wireless AP, Bluetooth, infrared, etc. for wireless network communication and transmission. The monitoring center is used to monitor and manage the above-mentioned devices and systems in real time, including storage and recording of monitoring data, sharing and publishing of monitoring information, etc.

[0043] In the embodiment of the present application, the intelligent energy management system is used for energy storage, consumption management and energy-saving control of the park, and provides reasonable energy scheduling and management strategies by real-time monitoring and analysis of energy usage to reduce the energy consumption and operating costs of the park. Among them, the intelligent energy management system includes a central control system, an energy management system, a power dispatching center, a power distribution control system, an energy storage control system, a photovoltaic control system and a photovoltaic array device.

[0044] Among them, the central control system is responsible for the coordination and management of the entire system, ensuring information exchange and collaborative work between various subsystems. The energy management system (EMS) is responsible for monitoring and managing the energy usage in the park, including electricity, water, natural gas, etc., and improving energy efficiency and reducing energy consumption through real-time data analysis and optimization strategies. The power dispatching center is specifically responsible for the dispatching and management of power resources. According to real-time data and forecast information, it optimizes power distribution to ensure the stability and efficiency of power supply. The distribution control system (i.e., distribution cabinet) is responsible for the distribution and management of electric energy. It is used for power distribution, voltage regulation, protection of electrical equipment, etc., to ensure the safety and efficiency of power distribution, and can transmit electric energy from the power grid to the load end and energy storage cabinet in the park. The energy storage control system (i.e., energy storage cabinet) is used to achieve efficient storage and utilization of energy, ensure that the energy storage and release process is efficient and safe, and help balance the supply and demand relationship of the power grid and adjust the load of the power grid through the process of charging and discharging. The energy storage cabinet includes a battery pack and a PCS (bidirectional converter). The PCS can convert DC power into AC power and transmit it to the power grid or to the user's load end. It can also draw power from the power grid and convert AC power into DC power to charge the battery pack. The photovoltaic control system (i.e., photovoltaic controller) is used to protect the battery pack from overcharging or over-discharging, and monitor and manage the overall operation of the photovoltaic power generation system. The photovoltaic panel converts solar energy into DC power and charges the battery pack through the photovoltaic controller. The photovoltaic array device is used to open and enable the photovoltaic panel and close the protection. The photovoltaic array device can be installed in an open area, such as a roof. The management personnel can control and maintain the photovoltaic energy device through the photovoltaic array device so that the photovoltaic panel can achieve the best use state.

One end of the screw rod 6 passes through the vertical plate of the right pedestal 2 and extends to the outside of the vertical plate. A second support plate 10 is provided on the outer side of the left pedestal 1. A second motor 11 is installed on the second support plate 10. The power output end of the second motor 11 is connected to the outer end of the screw rod 6. The other end of the screw rod 6 is rotatably connected to the vertical plate of the left pedestal 1. One end of the optical axis 7 is vertically fixed to the vertical plate of the left pedestal 1, and the other end of the optical axis 7 is vertically fixed to the vertical plate of the right pedestal 2. The two ends of the rotating shaft 5 are rotatably connected to the left pedestal 1 and the right pedestal 2 respectively through a first bearing seat (not shown). The two ends of the screw rod 6 are rotatably connected to the left pedestal 1 and the right pedestal 2 respectively through a second bearing seat (not shown).

[0047] A plurality of movable seats 12 are arranged side by side on the rotating shaft 5, the screw rod 6 and the optical axis 7. The photovoltaic panels 16 are arranged on both sides of the movable seats 12. When the outer dimensions of the main body of the array device remain unchanged, the movable seats 12 can be increased or decreased modularly according to actual conditions and needs. Three movable seats 12 are shown in the figure.

In order to realize that the rotating shaft 5 rotates and drives the worm wheel 124, one or more first clamping strips 127 are provided along the axial length direction of the rotating shaft 5, and one or more first clamping grooves that cooperate with the first clamping strips 127 are provided in the first central through hole of the worm wheel 124. For example, three first clamping strips 127 are provided, and the three first clamping strips 127 are arranged in a circular array with the axis of the rotating shaft 5 as the center line, such as Figure 5 and Figure 6 As shown. The second cavity 123 is arranged above the optical axis 7, and the linkage shaft 126 is in a spatially vertical relationship with the optical axis 7. The linkage shaft 126 is mounted in the second cavity 123, and one end of the linkage shaft 126 passes through the seat body 121 and extends outward to one side of the seat body 121. The other end of the linkage shaft 126 also passes through the seat body 121 and extends outward, and is connected to one end of the worm 125. The worm 125 is connected to the seat body 121 through a third bearing seat (not shown), and the linkage shaft 126 is connected to the seat body 121 through a fourth bearing seat (not shown). It can be seen from the above structural design that the forward and reverse start of the first motor can synchronously drive the rotating shaft, the worm wheel, the worm and the linkage shaft to rotate.

Fig. 9As shown, the connecting rod assembly 13 is composed of a connecting rod a131 at the head end, a connecting rod b132 at the tail end, and a plurality of connecting rods c133 between the head and the tail. The middle part of the connecting rod c133 is hinged to the bottom of the driven seat 129, and the head and tail of the plurality of connecting rods c133 are hinged to each other to form an intermediate section.

The end is hinged on the left base 1 or the right base 2 (the right base 2 is shown in the figure); therefore, combined with the design and connection of the above structure, it can be known that the second motor 11 drives the screw 6 to rotate forward and backward to first drive the active base 128 to move linearly. Due to the setting of the connecting rod assembly 13, the movement of the active base 128 drives each driven base 129 to move equidistantly in the same direction, and the connecting rod assembly 13 expands and opens (the moving base 12 is dispersed) or folds and contracts (the moving base 12 is gathered together).

[0053] Based on the above, when the photovoltaic panel 16 is not restricted by the fixing structure 15, the end of the plug-in column 154 abuts against the plug-in rack 14, the plug-in column 154 is in the countersunk hole 152, and the return spring 156 is compressed; when the photovoltaic panel 16 is inserted into the plug-in rack 14 and needs to be restricted and fixed, the handle 155 is used to pull the sliding block 151 to slide in the waist-shaped groove 145, during which the end of the plug-in column 154 always abuts against the plug-in rack 14 until the plug-in column 154 moves to the third through-hole 146, and the plug-in column 15 Under the elastic force of the return spring 156, the third through hole 146 is inserted into the plug hole 161 of the side frame of the photovoltaic panel 16, thereby achieving the restriction and fixation of the photovoltaic panel 16; when the photovoltaic panel 16 needs to be unlocked, the pull rod 153 is pulled outward by the handle 155 until the plug post 154 returns to the countersunk hole 152, the return spring 156 is compressed, and then the slide block 151 is pulled by the handle 155, so that the end of the plug post 154 abuts against the plug rack 14. Therefore, through the setting of the above-mentioned fixing structure 15, it is convenient to restrict, fix and unlock the photovoltaic panel 16, the operation is simple, and the disassembly and assembly of the photovoltaic panel 16 is more time-saving and labor-saving.

[0054] As an embodiment of the present application, the management system further includes a PLC controller and a motor driver connected to the PLC controller, the first motor 9 and the second motor 11 are connected to the motor driver, and the PLC controller and the motor driver are configured to achieve precise control of the first motor and the second motor, including start time, run time, stop time, etc. For example: set the time when there is light during the day to turn on and enable the photovoltaic array device, and set the time when there is no light at night to turn off and maintain the photovoltaic array device.

[0055] The working principle of the photovoltaic array device of this embodiment is as follows:

[0056] The first motor 9 and the second motor 11 operate independently, respectively controlling the rotating shaft 5 and the screw 6, so as to manipulate the plurality of photovoltaic panels 16 to synchronously realize two actions, namely, the following lateral movement and rotational tilting;

[0057] (1) The first motor 9 starts to drive the rotating shaft 5, and the rotating shaft 5 rotates to drive the worm wheel 124, which in turn drives the worm 125 and the linkage rod to rotate, thereby synchronously realizing the rotation of the photovoltaic panels 16 on each rack 14, thereby achieving the purpose of adjusting the tilt angle of the photovoltaic panels 16, so that the photovoltaic panels can achieve a better energy conversion state.

[0058] (2) The second motor 11 starts to drive the middle screw 6, and the rotation of the screw 6 drives the various moving seats 12 to move synchronously to disperse or gather together (depending on the rotation direction of the screw 6), thereby achieving the purpose of synchronously adjusting the position of each moving seat 12 on the rod body of the screw 6, that is, synchronously adjusting the distance between adjacent photovoltaic panels 16 on the device, so that the photovoltaic panels can better and more flexibly receive light to generate electricity.

[0059] (3) Opening and enabling state: the adjacent movable seats 12 are separated by a certain distance, and the photovoltaic panels 16 face upward to receive light and generate electricity. This state is as follows: Figure 2 As shown;

[0060] (4) Closed maintenance state: The adjacent mobile seats 12 are close to each other and gathered together, the front of the photovoltaic panel 16 is tilted downward, and the adjacent photovoltaic panels 16 on the left and right are stacked up and down, so as to reduce the pollution and damage to the front of the photovoltaic panel 16 caused by the external environment (rain, snow, strong wind, sandstorm, hail and other weather conditions), maintain the cleanliness and integrity of the front of the photovoltaic panel 16, reduce the cost of manual maintenance and cleaning, and improve the service life and operating efficiency of the photovoltaic panel 16. This state is as follows: Figure 3 shown.
