Detailed Description
The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for the purpose of understanding and controlling the technical solutions of the present invention, so as to define the protection scope of the present invention more clearly.
In view of the technical defects of the conventional ventilation opening in the aspects of air volume data acquisition, display, intelligent adjustment and the like, the designer actively researches and innovates to provide the fresh air ventilation opening with the functions of electric power storage and screen display and an energy supply method based on the ventilation opening for further optimization, so that a user can conveniently and quickly obtain fresh air data.
Most of the existing various air supply outlet forms are simple; the basic structure of the wind pipe comprises an outer frame for butting and positioning the wind pipe and blades with functions only limited to guiding wind direction, so that the requirements of data acquisition, display and intelligent control function expansion cannot be met functionally. The scheme is innovated on the basis of the inherent structure of the fresh air vent, and the indoor light energy and the pipeline wind energy are combined in a complementary energy recycling mode to supply energy to the vent independently, so that intelligent transformation is realized.
As can be seen from the principle, the flow schematic and the partial structure sectional view shown in fig. 1 to fig. 4, the fresh air vent comprises an air outlet monitoring unit and an energy supply unit which are integrally connected with each other in the air outlet body 1, wherein the air outlet monitoring unit 2 is mainly used for expanding the intelligent adjusting function of the air outlet and meeting the interaction with a user. In order to realize the functions, at least a controller 22 for signal interconnection, a sensor 21 for collecting air supply data and a display screen 23 for outputting detection results are arranged. The display screen can be a nixie tube display screen, an LCD display screen or various screens with display functions, and the appearance of the screen can be square, round and the like; the controller is selected according to the functions required to be realized by the intelligent air opening, the optional range comprises a PLC single chip microcomputer, an MCU/CPU processor and the like, and at least the requirements of converting signals measured by the sensor and displaying data on a display screen are met. As the energy supply basis of above air-out monitoring unit, pleasing to the eye and the cost input for avoiding destroying interior decoration's vision, do not consider the solution that relies on external power supply line, this scheme design has integrateed the energy and has recycled the energy supply unit from the electricity generation at the vent innovation, be equipped with battery 3 in it, utilize the first portion A of generating electricity from of fresh air conversion electric energy in the tuber pipe, utilize indoor illumination conversion electric energy second portion B of generating electricity from, and two way from the power generation portion through scene complementary control circuit 4, prevent returning and rich electric bleeder circuit 5 and power automatic switching circuit 6 and controller 21 interconnection access battery 3. Through the circuit design of further optimization, utilize the battery to satisfy the energy storage, maintain air-out monitoring unit operation when the energy that can recycle is not enough relatively, perhaps lead when the energy that can recycle is sufficient relatively and maintain air-out monitoring unit operation. And this battery is integrative to be inlayed and to be located in the air-out monitor cell, and electric capacity and output satisfy the air-out monitor cell and move required.
In view of further refinement of the component structure, the first self-generating unit a is composed of blades, a speed increaser, and a permanent magnet synchronous generator, and an AC-to-DC converter is connected to an output end of the permanent magnet synchronous generator, as shown in fig. 5. In order not to influence the normal air supply of the ventilation opening, each component of the energy supply unit selects a miniature device with small volume. This from electricity generation portion can drive the flabellum and rotate when the vent has the right amount to send wind, and the flabellum pivot drives the speed increaser and drives micro generator active cell to make this generator can continuously output the electric energy. The electric energy exists in an alternating current mode and cannot be directly used for charging a storage battery or working and running of a controller, so that alternating current and direct current conversion needs to be carried out on output to output direct current voltage.
And the above-mentioned second is from the solar energy component of electricity generation part B2 in air-out monitoring unit as an organic whole integration, and the battery piece among the solar energy component is for receiving indoor illumination, embedded in air-out monitoring unit 2 towards the surface of indoor environment and surround display screen 23 and distribute. Although the power generated by the solar module is proportional to the area of the battery piece, the energy level of the wind output monitoring unit is sufficient to meet the energy requirement of the first self-generating unit a as the same level of assistance of the first self-generating unit a.
On the basis that the self-generating electricity is realized to the above-mentioned pipeline wind energy and indoor luminous energy of utilization, because the air supply wind speed often has fluctuation, thereby lead to output voltage unstable, the electric energy of solar energy component output also can cause output voltage unstable because of the unstability of indoor luminous flux in addition, when both collect together, can cause current crosstalk and refluence because of there being the pressure differential, cause the damage of generating heat of system under the serious condition, for solving this problem, as shown in fig. 4, this scheme introduces wind-solar hybrid control circuit and collects two tunnel unstable electric energy, make the electric energy that both produced can not flow backwards. Similarly, besides two paths of unstable self-generating electricity need to be regulated, the charging and discharging control of the storage battery under different voltage environments also needs to be reliably protected. Therefore, the wind-solar complementary control circuit and the storage battery are both connected to the anti-reverse and rich-electricity discharge circuit, and the output end of the power supply automatic switching circuit is used for supplying energy and outputting. In addition, the controller is provided with a filter circuit and a voltage stabilizing circuit (conventional devices are not shown) facing the input end of the energy supply unit so as to provide a safe and stable power supply environment facing the intelligent air outlet.
In detail, the function of the circuit shown in fig. 4 is explained, and the micro wind power generator and the photovoltaic cell module are connected together through the wind-solar hybrid control circuit by the direct current voltages output by the respective conversion circuits, and then the power storage module is charged and the rear-end control system is powered by the anti-reverse and rich-power discharge circuit. The miniature wind power generator is basically the same as the control circuit of the photovoltaic cell assembly. Firstly, filtering is carried out through a capacitor and an inductor to obtain stable and continuous voltages Uf and Ug, when an MCU (microprogrammed control unit) of a control system outputs a charging signal Vg (B2) or Vf (A2) to be at a high level, a triode is conducted, the grid of a mos tube MA or MB is changed into a low level, mos is conducted, and a miniature wind driven generator or a photovoltaic cell module can provide electric energy for the rear end. Tvs in the complementary circuit plays a role in protection, when the output voltage of the miniature wind driven generator or the photovoltaic cell module exceeds the reverse cut-off voltage of tvs, the miniature wind driven generator or the photovoltaic cell module is broken down and conducted, so that the grid of the mos tube MA or MB is always at a high level, the mos tube MA or MB cannot be conducted even if the MCU of the control system continuously outputs a high level (Vg or Vf), and the rear-end circuit and the energy storage module are automatically prevented from being damaged due to overhigh voltage. When wind energy and light energy are excessive or one path is abnormal, the MCU of the control system can select Vg or Vf to output high level or low level, and the effects of automatically adjusting input voltage and protecting the system are achieved.
In the power supply automatic switching circuit 6: when the output voltage of the micro wind driven generator and the photovoltaic cell assembly is greater than or equal to the voltage of the energy storage module, namely uG ≧ uS, the conduction condition is not satisfied, the PMOS is cut off, the current supplies power to the control system through a diode, the PMOS is prevented from being cut off by utilizing the one-way conductivity of the diode, and at the moment, the micro wind driven generator and the photovoltaic cell assembly not only provide the voltage for the energy storage module but also provide electric energy for the control system, so that a stable power supply environment can be provided for ensuring safe and stable operation of the system.
In the above anti-reverse and rich-electric discharge circuit 5: the electric energy of the miniature wind driven generator and the photovoltaic cell assembly is gathered together, and the unidirectional conductivity of the diode is utilized to prevent the two voltages from flowing reversely to the other assembly to cause damage due to the fact that the two assemblies output voltage difference when the two voltages are gathered together. After passing through the anti-reverse circuit, the collected electric energy can supply power to the power storage module and the control system. Because the control system adopts the low-power consumption design, under the condition that both light energy and wind energy are abundant, the energy obtained by the system is excessive, at the moment, if the control system detects that the power supply of the system is still abundant after the lithium battery is fully charged, in order to protect the wind driven generator and the photovoltaic module, a power discharge control signal 51 of the control system outputs a high level, the mos tube MC is conducted, and the redundant electric energy is converted into heat energy through the high-power discharge resistor, so that the surplus electric energy is discharged.
Under the normal condition, various controller hardware is internally provided with a memory, and when the intelligent air inlet is applied, the air supply data acquired by the sensor can be recorded in real time and updated regularly, and can be output and presented through a display screen after being called by the controller. More optimally, the controller adopts an ultra-low power consumption design, the controller enters an ultra-low power consumption sleep mode regularly during system design, then wakes up the MCU regularly to collect sensor data and displays the sensor data on the LCD, and because the LCD has extremely low power consumption, the data is always displayed, and the whole sleep and wake-up process is circulated and repeated, so that the system can run normally and continuously. After the sleep mode is started, most of electric energy is stored in the storage battery, and the storage battery is full, charging is stopped, and the battery protection mode is entered.
From the expansion of the function of realizing the regulation outside the intelligent air port displaying the air quantity, the fresh air vent is provided with an air control unit for regulating the air outlet direction and the air quantity, for example, a micro motor for switching the air port blade direction or regulating the size of a ventilation space, and the driving ends of the air control units are connected with a controller to be controlled, for example, the regulation function is realized through short-distance wireless communication mode interactive signals with extremely low energy consumption.
As can be understood by combining the flow chart shown in FIG. 2, the fresh air ventilation opening with the improved structure provides a brand-new self-generating energy supply method. The first self-generating part A operates independently, converts mechanical energy of fresh air into alternating current, and inputs the alternating current into the wind-solar hybrid control circuit after the alternating current is rectified and converted into direct current; the second self-generating part B operates independently and converts indoor light energy into direct current to be input into the wind-solar complementary control circuit; and the wind-solar complementary control circuit and the storage battery are used for adaptively and controllably supplying energy to the air outlet monitoring unit according to the environmental energy states at different time intervals.
Depending on the wind-solar complementary control circuit and the anti-reverse and electricity-rich discharge circuit, specifically, when the output voltage of the wind-solar complementary control circuit is greater than the working voltage of the storage battery, the energy supply is dominated by the wind-solar complementary control circuit and the storage battery is charged; when the output voltage of the wind-solar hybrid control circuit is smaller than the working voltage of the storage battery, the energy supply is guided by the storage battery. Wherein the reverse-proof and rich-electricity discharge circuit simultaneously plays a role in switching energy supply.
In conclusion, the new air vent and the improved scheme of the energy supply thereof have prominent substantive features and remarkable progress: according to the scheme, wind energy and light energy under a fresh air system and an application scene are fully utilized, self-adaptive power generation, energy storage and energy supply are realized by additionally arranging the energy supply unit based on vent integration, the vent is convenient to install, required functions can be realized after the ventilation is replaced, and indoor decoration is not required to be damaged due to an external power supply line.
In addition to the above embodiments, the present invention may have other embodiments, and any technical solutions formed by equivalent substitutions or equivalent transformations are within the scope of the present invention as claimed.
