[0002] In recent years, with the rapid growth of residents' income and the steady improvement of urbanization level in my country, automobile consumption has increased significantly. With the continuous and substantial increase in the number of cars, problems such as traffic congestion and parking difficulties have become increasingly prominent. The resulting large number of traffic violations such as parking on the road have affected people's living order and quality of life, causing the traffic situation to deteriorate. Deep well vertical lifting three-dimensional intelligent garage can effectively use limited site conditions to solve the problem of difficult parking in cities, and help balance the land use contradiction between vehicle parking and urban planning and construction. Therefore, deep well vertical lifting three-dimensional intelligent garage has gradually become an indispensable public infrastructure for modern people's daily travel.

[0003] Since the three-dimensional intelligent garage works in an outdoor environment for a long time, various factors such as weather may cause the core components of the garage, such as motors and bearings, to overheat, over-rotate, wear and other faults. At present, low-energy detection sensors are mainly used to detect vibration, temperature, electrical characteristics and other signals during the operation of core components such as motors and bearings, and then the detection signals are transmitted to the database and simulation module through the communication module for simulation to obtain the state trend of the core components, and the health status of the core components is judged by the state trend, and the fault diagnosis results are given through the visualization module, so that the remote duty room can control the three-dimensional intelligent garage access control system and warning system through the communication module according to the fault diagnosis results.

[0029] The present embodiment is described in detail below, and examples of the embodiment are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] A passive power supply circuit and device for a stereoscopic car park based on regenerative power generation according to this embodiment will be described below with reference to the accompanying drawings.

[0031] Figure 1 FIG. 1 is a schematic diagram of a passive power supply circuit for a stereo garage based on regenerative power generation according to an embodiment of the present invention. Figure 1 As shown, the passive power supply circuit of the stereo garage includes a piezoelectric module, a rectifier module, an electric energy transmission subcircuit, an energy storage unit and a power receiving device connected in sequence, wherein the power receiving device includes a low-energy consumption sensor, a communication module and a controller, etc.

[0032] In this embodiment, the rectifier module is a circuit composed of diodes D1 to D4. The power transmission subcircuit includes a capacitor C and two coupled inductors, namely a first coupled inductor L1 and a second coupled inductor L2. Specifically, the structure of the passive power supply circuit of the stereo garage is that the output end of the piezoelectric module is connected to the input end of the rectifier module, the output end of the rectifier module is connected to the first end and the second end of the first coupled inductor L1 through the capacitor C, the second end of the first coupled inductor L1 is connected to the second end of the second coupled inductor L2 and grounded, the first end and the second end of the second coupled inductor L2 are respectively connected to the energy storage unit, and the energy storage unit is connected to the power receiving device.

[0033] When the multi-story parking garage is operating normally, that is, the external power supply is supplying power normally, the piezoelectric module generates alternating current through the piezoelectric effect, the rectifier module converts the alternating current into direct current, and the power transmission subcircuit transmits the direct current to the energy storage unit. The energy storage unit then stores the direct current and supplies power to the powered equipment when the multi-story parking garage is powered off. In this way, when the multi-story parking garage is powered off, the power supply of modules such as low-energy consumption sensors in the multi-story parking garage can be guaranteed.

[0034] like Figure 2 As shown, the piezoelectric module includes a fixed ring 1, a first piezoelectric component 3 and a plurality of second piezoelectric components 4, namely, piezoelectric cantilever beams. The fixed ring 1 is fixed on the wall, and a plurality of fixed baffles 2 are arranged on the inner surface of the fixed ring 1. Figure 3 As shown, the piezoelectric first component 3 includes a rotating component 5 and a plurality of connecting components 6 , and the plurality of connecting components 6 are arranged at intervals around the bottom end of the rotating component 5 .

[0035] Please continue to refer to Figure 2 One ends of the plurality of piezoelectric second components 4 are respectively connected to the corresponding plurality of connecting members 6 of the piezoelectric first components 3 , and the other ends of the plurality of piezoelectric second components 4 are respectively arranged close to the corresponding fixed baffles 2 .

[0036] like Figure 4 As shown, each piezoelectric second component 4 includes a substrate 7 and a piezoelectric film 8, and the piezoelectric film 8 is arranged on the side surface of the substrate 7. The material of the substrate 7 is a metal material, such as copper material. The material of the piezoelectric film 8 can preferably be PVDF (polyvinylidene fluoride) material.

[0037] Please continue to refer to Figure 2 and Figure 4 A first connecting hole 9 is formed at one end of each substrate 7, and a second connecting hole is formed on each connecting piece 6 of the first piezoelectric component 3. The first connecting hole 9 and the second connecting hole are fixedly connected by bolts and nuts, i.e., a fixing component 10.

[0038] It should be noted that the top end of the rotating component 5 is connected to the rotating component of the lifting mechanism in the parking space lifting platform, and the rotation of the rotating component of the lifting mechanism can drive the rotating component 5 to rotate.

[0039] like Figure 5 As shown, the passive power supply circuit of the stereo garage also includes an electric coupling, a main control module, a generator and a battery. The electric coupling, the generator and the battery are connected in sequence, and the electric coupling is also connected to the lifting mechanism rotating part and the main control module respectively; wherein, when the main control module detects that the parking lifting platform is fully loaded and moving upward, it controls the electric coupling to be disconnected; when the main control module detects that the parking lifting platform is unloaded or loaded and moving downward, it controls the electric coupling to be connected, so that when the lifting mechanism rotating part rotates, the generator is driven to operate through the electric coupling, and the generated electric energy is stored in the battery for emergency standby.

[0040] The working principle of the passive power supply circuit of the stereo garage based on regenerative power generation is:

[0041] When the stereo garage is operating normally, the motor in the parking space lifting platform drives the lifting mechanism rotating part to rotate, and the lifting mechanism rotating part rotates to drive the rotating part 5 of the piezoelectric first component 3 in the piezoelectric module to rotate. The rotating part 5 rotates through multiple connecting parts 6 to drive multiple piezoelectric second components 4, i.e., piezoelectric cantilever beams, to rotate. When the multiple piezoelectric second components 4 rotate, they will be blocked by multiple fixed baffles 2 in the fixed ring 1, so that the piezoelectric film 8 on the substrate 7 will deform accordingly to produce piezoelectric effect, thereby generating charges and generating alternating current. The generated alternating current is rectified into direct current by the rectifier module and then coupled to the energy storage unit for energy storage through the DC coupling circuit composed of the capacitor C, the first coupling inductor L1 and the second coupling inductor L2, i.e., the power transmission subcircuit. When the stereo garage is powered off, the energy storage unit can supply power to the power receiving device with the stored electric energy. Therefore, when the stereo garage system is powered off, the low-energy consumption sensor and other module power supplies in the stereo garage system can be guaranteed, thereby ensuring the real-time monitoring of the health status of the core components of the stereo garage system, and thus facilitating the stable and safe operation of the stereo garage system.

[0042] Furthermore, when the main control module detects that the parking lift platform is fully loaded and moving upward, it can control the electric coupling to disconnect. When the main control module detects that the parking lift platform is unloaded or loaded downward, such as when the mass sensor and the speed sensor detect that the parking lift platform is unloaded or loaded downward, it can control the electric coupling to connect, so that when the rotating part of the lifting mechanism rotates, the generator is driven to operate through the electric coupling, and the generated electric energy is stored in the battery, so that the battery can store strong electric energy, and then when the three-dimensional parking garage system is powered off, the battery releases strong electricity to power the parking lift platform control system, so that the parking lift platform can operate normally, ensuring that vehicles can enter and exit the garage normally when the three-dimensional parking garage system is powered off.

[0043] Furthermore, the present invention also provides a passive power supply device for a stereoscopic car park based on regenerative power generation, which includes the passive power supply circuit for a stereoscopic car park based on regenerative power generation described above.

[0044] In summary, the present invention provides a passive power supply circuit and device for a stereo garage based on regenerative power generation, wherein the passive power supply circuit for the stereo garage includes a piezoelectric module, a rectifier module, an electric energy transmission subcircuit, an energy storage unit and a power receiving device connected in sequence, wherein when the stereo garage is operating normally, the motor in the parking space lifting platform drives the lifting mechanism rotating part to rotate, the lifting mechanism rotating part rotates to drive the rotating part of the piezoelectric first component in the piezoelectric module to rotate, the rotating part rotates through multiple connecting parts to drive multiple piezoelectric second components to rotate, and the multiple piezoelectric second components rotate when they are blocked by multiple fixed baffles in the fixed ring, so that the piezoelectric film will deform to generate piezoelectric effect to generate charge, and generate alternating current, and the generated alternating current is rectified into direct current by the rectifier module and then transmitted and stored in the energy storage unit through the electric energy transmission subcircuit. When the stereo garage is powered off, the energy storage unit will power the power receiving device with the stored electric energy, so that when the stereo garage system is powered off, the low-energy consumption sensor and other module power supplies in the stereo garage system can be guaranteed, thereby ensuring the real-time monitoring of the health status of the core components of the stereo garage system, and then facilitating the stable and safe operation of the stereo garage system.

[0045] In addition, the passive power supply circuit of the multi-story parking garage also includes an electric coupling, a main control module, a generator and a battery. When the main control module detects that the parking lifting platform is fully loaded and moving upward, the electric coupling can be controlled to be disconnected; when the main control module detects that the parking lifting platform is unloaded or loaded and moving downward, the electric coupling can be controlled to be connected, so that when the rotating parts of the lifting mechanism rotate, the generator is driven to operate through the electric coupling, and the generated electric energy is stored in the battery, so that when the multi-story parking garage system is powered off, the battery can release strong electricity to power the parking lifting platform control system, thereby facilitating the normal operation of the parking lifting platform and ensuring that vehicles can enter and exit the garage normally.
