Description

Independent photovoltaic intelligent curtain system

technical field

The utility model belongs to the technical field of photovoltaic power generation, energy storage and intelligent curtains, and relates to an independent photovoltaic intelligent curtain system.

Background technique

As an important part of smart home, electric curtains can be opened and closed electrically according to the requirements of residents, and have the functions of managing indoor light, maintaining indoor temperature, preventing sun exposure, and protecting the privacy of residents. However, the current electric curtains mainly rely on the mains to supply power to the curtain motors, so the installation of electric curtains must reserve power plugs, but many users (especially those in old houses) often do not have the conditions to reserve power, and the transformation of power wiring not only The high cost and the possibility of destroying the beauty of home decoration greatly restrict the consumer group's demand for electric curtains. In response to this problem, some manufacturers have designed and produced wire-free lithium battery electric curtains, using rechargeable batteries to solve the problem of motor power supply, but this method still has limitations, requiring the battery to be removed from time to time for charging, which cannot completely solve the power supply of electric curtains. question.

As a renewable energy, solar energy is clean, environmentally friendly, inexpensive, and has high energy density. It has been widely used in production and life in recent years. With the breakthrough of photovoltaic power generation technology, the power generation efficiency has been continuously improved. For example, the energy efficiency conversion rate of thin-film solar cells has exceeded 20%, which undoubtedly provides the necessary conditions for miniaturized and lightweight photovoltaic power generation systems. An independent photovoltaic power generation system without AC load is generally composed of solar panels, controllers, batteries, and DC loads. Among them, the performance of the battery directly affects the stability of the system operation, so the battery is usually required to have the characteristics of low self-discharge rate, long service life, strong deep discharge capability, high charging efficiency, easy maintenance, and wide operating temperature range. Compared with other batteries, lithium-ion batteries are widely used in stand-alone photovoltaic systems because of their small volume ratio, high energy, high cycle charge times, and long battery life.

At the same time, the electric curtains are close to the window and can obtain sufficient solar energy, and it is very possible to use the solar energy to power the electric curtains. Some patents have proposed this idea:

In the patent "A Solar Curtain" with publication number CN207813459U published on September 4, 2018, it relates to a venetian blind with adjustable inclination angle of solar panels based on a drum structure.

In the patent "Remote Intelligent Rolling Shutter Type Thin Film Solar Curtain" published on October 27, 2017 with the publication number CN107302338A, it relates to a rolling shutter thin film solar curtain that can be remotely controlled to unfold or roll.

The above patents are only aimed at electric venetian blinds or electric roller blinds with a very low market share, and cannot be used for electric fabric curtains with high usage rates, and the above patents have no specific technical means for the selection and arrangement of batteries and motors.

In the patent "A Solar Smart Curtain Device" published on November 4, 2015 with the publication number CN105011724A, it relates to a smart curtain device with solar panels installed on the outside of the window.

The patent "A Solar Intelligent Blackout Curtain" published on January 5, 2018 with the publication number CN206836757U relates to a device for automatically closing the curtain through the use of solar panels and electromagnets.

The above patent proposes to use solar energy to power electric curtains, but it lacks the protection of solar modules, batteries and other components, and cannot prevent problems such as hot spot effect and battery reverse charging; and the selection of batteries and motors is unreasonable, resulting in large size of the device , Heavy weight and complicated installation.

The publication number CN208551027U published on March 1, 2019 "An Intelligently Controlled Electric Curtain" proposes an electric curtain that uses a booster module to speed up battery charging, but does not specify the specific design of the booster module.

To sum up, the installation of electric curtains needs to reserve power supply, which greatly hinders its popularization among users of old houses. Micro photovoltaic power generation and energy storage technology can solve this pain point. However, it does not yet have the advantages of light weight, easy installation and maintenance. Simple, stable and modular solution.

Example 1

In the zero-energy independent photovoltaic intelligent curtain system of this embodiment, the power transmission route is solar module→battery module→load, and the solar module cannot directly supply power to the load through the control circuit.

As shown in FIG. 3, a zero-energy independent photovoltaic intelligent curtain system includes a solar module 3, a solar charge management module 8, a battery module 7, a main control module 6, a curtain motor module 5, and an electric guide rail 1. , a blackout curtain 4. The battery module 7 is respectively connected with the solar charging management module 8 , the main control module 6 and the curtain motor module 5 . The output shaft of the curtain motor module 5 is connected with the electric guide rail 1 , and the shading curtain 4 is connected with the electric guide rail 1 through the hanging wheel 2 . The shading curtain 4 is located directly under the electric guide rail 1, the curtain motor module 5 is located under one end of the electric guide rail 1, the main control module 6 is located directly under the curtain motor module 5, and the battery module 7 is located directly under the main control module 6. The solar module 3 and the solar charge management module 8 can be sewn on the blackout curtain 4 .

The solar module 3 can be selected as a thin-film solar module, such as a CIGS thin-film solar cell, which has the characteristics of high energy efficiency conversion rate, light weight, thinness, and good flexibility. Of course, the solar module 3 can also be a rigid solar module, such as a crystalline silicon solar module, as long as the modules that can achieve the purpose of solar power generation are within the protection scope of the present invention. Further, considering the voltage loss when the working temperature of the solar module 3 rises and the voltage drop loss through the electronic components, a thin-film solar module with an output voltage of 15V under standard light intensity can be selected; the output power of the solar module 3 depends on the specific load power consumption The amount of electricity, working environment and other factors are determined, and the range should be between 3W-5W, which can ensure that under non-extreme climatic conditions, all the electricity required for the operation of the smart curtains in the system comes from the DC independent photovoltaic power generation system, while the solar energy The expansion area of component 3 is relatively reasonable and will not affect the visual aesthetics of the original home decoration environment.

The entire power generation process of the solar module 3 is regulated and managed by the solar charge management module 8. As shown in Figure 2, a Schottky diode D1 is connected to the positive pole of the input voltage Vin to prevent the positive and negative poles of the power supply from being reversed, and the unidirectional conduction of the diode is used. It can be known that the input voltage Vin and the voltage regulator circuit form a loop at this time, and the voltage regulator circuit can work normally. When the positive and negative poles of the input voltage are reversed, the Schottky diode D2 prevents the current from flowing, and the voltage regulator circuit at this time cannot form a loop, which will not cause any impact on the voltage regulator circuit. If there is no diode for preventing the reverse connection of the power supply, when the power supply is reversed, the current flowing through the voltage stabilizer circuit will be greater than the current under normal conditions, which will cause the voltage stabilizer circuit to be burned.

A Schottky diode D2 is reversely connected between the input voltage Vin (ie, the current output terminal Vin of the solar module) and the ground GND to prevent reverse charging. When the power is off, the reverse voltage generated on the inductor L1 and the Schottky diode A current path is formed between the diodes D1, which is clamped by the Schottky diode D1, and will not generate a reverse charging voltage on the power supply, which will damage the power supply.

The SC pin and SE pin of the voltage regulator integrated chip MC34063 are grounded. At this time, the inductor L1 begins to store energy, and the electrolytic capacitor C1 provides energy to the load. When the on-chip switch is turned off, the input voltage Vin and the inductance L1 provide energy to the load and the electrolytic capacitor C1 at the same time. During the energy release period of the inductance L1, since the polarity of the electromotive force at both ends is the same as that of the power supply, it is equivalent to two power supplies. connected in series, the resulting voltage on the load will be higher than the input voltage Vin. The output voltage value is adjusted by changing the value of the adjustable resistor R4 and the fixed value resistor R5. The output voltage conforms to the following formula: Vout=1.25V*(1+R4/R5), of which 1.25V is the reference voltage. At the same time, C3 in Figure 2 is a timing capacitor, which determines the on-off time of the switch tube in the chip, C2 is a filter capacitor, R2 and R3 are current limiting resistors, and D0 is a power indicator light.

As shown in FIG. 1 , the battery module 7 may include a rechargeable lithium-ion battery pack and a battery management module.

The battery management module has functions such as overcurrent protection, overvoltage protection, short circuit protection, overvoltage protection, and overdischarge protection. The entire charging and discharging process of the system is monitored and adjusted by the battery management system to ensure safe and reliable operation and prolong the service life of the lithium battery. The battery pack and the battery management module are connected to the main control unit through a double-sided buckle structure. In addition to daily charging through the photovoltaic power generation system, they can also be disassembled and charged with an adapter.

Please refer to FIG. 3 again, the curtain motor module 5 includes a driving motor, an electric guide rail 1 and a hanging wheel 2, etc., wherein the output end of the driving motor is connected to the transmission rod on the electric rail 1, and the transmission rod is connected to the hanging wheel 2. The wheel 2 is meshed, and the rack portion that meshes with the hanging wheel 2 is processed on the side of the shading curtain 4. In this way, the hanging wheel 2 is driven to rotate by the driving motor, thereby driving the curtain to realize opening and closing. Specifically, the output shaft is in a clockwise direction. Rotate, drive the hanging wheel 2 to rotate in the counterclockwise direction, thereby driving the shading curtain 4 to move in the horizontal direction, and realize the opening function of the shading curtain 4; The curtain 4 moves in the horizontal direction to realize the closing function of the blackout curtain 4 . Among them, the drive motor is a DC gear motor, with a rated working voltage of 12V, a rated torque of 1N m, and a rated speed of 85rpm. The structure is compact, which is beneficial to the lightweight of the system.

The main control module 6 consists of a communication unit, a motor drive unit and a display unit. The communication unit is used to receive external signals, and the motor drive unit is used to receive the signal fed back by the communication unit and process and output the execution signal, thereby controlling the start and stop of the curtain motor; the display unit is used to display the current control mode of the smart curtain.
