Description

Technical Field

[0002] In recent years, with the rapid development of urban rail transit in my country, subway transportation has played an important role in alleviating urban traffic congestion and solving the problem of large passenger flow in urban public transportation. The existing subway entry and exit methods mainly include ticket swiping and QR code or NFC payment.

[0003] Passengers need to carry physical tickets or IC cards to enter the station, which is not much different from traditional manual ticket checking. The convenience and riding experience are low, the labor cost is high, and it cannot meet social needs.

[0004] Using QR codes or NFC to pay requires passengers to use devices such as smartphones. Although this method is an improvement over the traditional ticket-swiping method, it still causes confusion and inconvenience for passengers who are not familiar with or do not have the corresponding equipment. In addition, when using this method to enter and exit the station, passengers are required to open the QR code and place it at the designated sensing position when entering and exiting the station. The one-person-one-swipe entry and exit mode greatly reduces the efficiency of traffic.

[0005] Currently, subway stations have huge passenger flow and are prone to congestion, especially during peak hours on weekdays, Spring Festival travel or holidays. The above two ways of entering the station require passengers to queue up and wait at the entrance, which can easily cause congestion, trigger trampling or gate accidents, and cause safety accidents.

[0036] In the present invention, the pressure self-generating module 4 may adopt a piezoelectric ceramic power generation component; the piezoelectric ceramic power generation component belongs to the conventional technology in this field and will not be described in detail here.

[0037] In the present invention, a pressure self-generating module 4 is specially designed which combines friction electrode power generation with piezoelectric ceramic power generation, and can effectively solve the disadvantage of low power generation efficiency of piezoelectric ceramics.

[0038] In this embodiment, the pressure self-generating module 4 includes a plurality of groups of self-generating units uniformly arranged under the floor around the gate, each group of self-generating units includes a top plate 5, a bottom plate 6 and a plurality of groups of piezoelectric vibrators arranged between the top plate 5 and the bottom plate 6, the piezoelectric vibrator includes a telescopic sleeve 7 and a piezoelectric ceramic ring 8 coaxially arranged in the telescopic sleeve 7, the lower part of the telescopic sleeve 7 is connected to the piezoelectric vibrator mounting hole 10 opened on the bottom plate 6 through a fixing seat 9; the upper end surface of the piezoelectric ceramic ring 8 is sequentially provided with a PMMA (polymethyl methacrylate) layer and a PDMS (polydimethylsiloxane) layer from top to bottom. ) layer, an elastic mechanism is arranged in the piezoelectric ceramic ring 8, the lower end of the elastic mechanism is connected to the bottom plate 6, and a matching metal pressing plate 11 is also arranged in the telescopic sleeve 7 above the piezoelectric ceramic ring 8, and the lower surface of the metal pressing plate 11 is provided with a PDMS (polydimethylsiloxane) layer; when the elastic mechanism is in the original length state, the lower surface of the metal pressing plate 11 does not contact the upper end surface of the piezoelectric ceramic ring 8; after the top plate 5 is driven by the downward pressure to drive the elastic mechanism to shrink downward, the lower surface of the metal pressing plate 11 contacts the upper end surface of the piezoelectric ceramic ring 8; the current output end of the self-generating unit is connected to the storage module 3 through a wire.

[0039] In this embodiment, the elastic mechanism can adopt a spring 12, and the spring 12 is arranged in the piezoelectric ceramic ring 8 through a spring seat 14 provided with a guide column 13. The outer diameter of the spring seat 14 is adapted to the inner diameter of the piezoelectric ceramic ring 8, and the spring 12 is sleeved on the guide column 13; the lower end of the spring seat 14 is provided with positive and negative electrode terminals 15 that penetrate the fixing seat 9 and the base plate 6, and the input end of the positive electrode terminal is connected to the positive output end of the piezoelectric ceramic ring 8 and the PDMS layer provided on the lower surface of the metal pressing plate 11 in sequence through a wire; the input end of the negative electrode terminal is connected to the negative output end of the piezoelectric ceramic ring 8 and the PDMS layer on the upper end surface of the piezoelectric ceramic ring 8 in sequence through a wire; the output end of the positive and negative electrode terminals 15 is connected to the storage module 3 through a bridge rectifier 16 and a transformer 17 in sequence through a wire. By adjusting the stiffness and pressure distribution of the spring 12, not only can the air gap between the lower surface of the metal pressing plate 11 and the upper end surface of the piezoelectric ceramic ring 8 be maintained and the adhesion between the friction layers be reduced, but also the piezoelectric ceramic ring 8 can be deformed to generate current when stress is generated, and the two PMMA layers and PDMS layers can be quickly separated when the stress disappears, resulting in more efficient power conversion.

[0040] During the use of each group of self-generating units, when pressure acts on the floor, the pressure will be transmitted to the piezoelectric vibrator through the floor and the top plate 5. The piezoelectric vibrator will vibrate and produce strain when receiving the pressure, and the piezoelectric effect will occur inside to generate charge. The charge gathers into current and moves along the wire to the bottom bridge rectifier 16 for rectification and filtering. The rectified and filtered current is gathered to the transformer 17 for boosting and voltage stabilization, and finally transmitted to the power storage module 3 for energy storage supply;

[0041] At the same time, the metal pressing plate 11 and the piezoelectric ceramic ring 8 form a sandwich structure of PDMS layer, PMMA layer and PDMS layer. Since the PMMA layer and the PDMS layer are two materials with different polarities, when pressure is applied to the piezoelectric vibrator, the PMMA layer and the PDMS layer are deformed to generate charge gain and loss, and the charge is gathered into current and moves along the wire to the bottom bridge rectifier 16 for rectification and filtering. The rectified and filtered current is gathered in the transformer 17 for boosting and voltage stabilization, and finally transmitted to the battery for energy storage supply.

[0042] In the present invention, each group of self-generating units includes 9 groups of piezoelectric vibrators evenly arranged, the output ends of the 9 groups of piezoelectric vibrators are connected in a series structure, and the outputs of several groups of self-generating units are connected in a parallel structure, which effectively solves the working abnormality and damage problems caused by parallel and series connection of the circuit, and can realize the function of independent replacement after a group of self-generating units is damaged, without affecting the use effect of the entire pressure self-generating module 4, and because the self-generating unit is easy to disassemble and maintain, the later use and maintenance costs are effectively reduced.

[0043] In the present invention, the bridge rectifier 16 can be arranged in the bottom plate 6 , the power storage module 3 can be a battery; and the transformer 17 can be arranged inside the gate housing 1 .

[0044] In the present invention, a guiding and diverting device for guiding passengers to queue in an orderly manner and / or controlling the number of passengers queuing at the gate channel, such as a compartment 18 with an opening and closing door 20, can also be arranged outside the gate. The opening and closing door 20 is driven by an opening and closing door driving mechanism 21 (cylinder rod, etc.), and the compartment 18 can guide passengers to queue in an orderly manner, and at the same time, with the aid of a camera 18 or other collection device capable of detecting the number of passengers queuing at the gate channel in the compartment 18, when the number of passengers queuing at the gate channel reaches a set upper limit threshold, the opening and closing door 20 of the compartment 18 can be controlled to close, so as to prevent passengers outside the compartment 18 from continuing to enter and causing safety hazards.
