The above and other objects, features and advantages of the present invention will become more <RTIgt;

The technical features, contents, and advantages of the present invention, as well as the advantages thereof, can be understood by the present inventors, and the present invention will be described in detail with reference to the accompanying drawings. The subject matter is only for the purpose of illustration and description. It is not intended to be a true proportion and precise configuration after the implementation of the present invention. Therefore, the scope and configuration relationship of the attached drawings should not be interpreted or limited. First described.

The embodiments of the curtain remote control system according to the present invention will be described below with reference to the related drawings. For the sake of understanding, the same components in the following embodiments are denoted by the same reference numerals.

Please refer to Figures 1 and 2 together, which is a block diagram and a system architecture diagram of the curtain remote control system of the present invention. The curtain remote control system 100 of the present invention is applied to allow the user to remotely control the opening and closing of the curtain 9 and the opening of the blade. The curtain remote control system 100 includes a proximal end 10 and a distal end 20.

For the portion of the proximal end 10, the proximal end 10 is disposed on the window covering 9, and includes a limit switch 11, a driving module 12, a power supply module 13, a wireless transmission module 14, and a control module 15. The limit switch 10 can be a micro switch, which is disposed at the top of a scrolling stroke when the curtain 9 is rolled up to be triggered to generate a limit signal. The drive module 12 is configured to drive the curtain to roll up or unfold, or to drive the blade of the window 9 to rotate. Further, the driving module 12 can include a stepping motor 121 and a strong torque motor 122. The stepping motor 121 is used to drive the curtain 9 to be rolled up or unfolded, and the strong torque motor 122 is used to drive one of the curtains 9 to rotate.

The power supply module 13 is configured to receive solar energy and convert it to electrical energy, and to store electrical energy to supply electrical energy to various components of the remote control curtain system 100. The wireless transmission module 14 is configured to receive a control signal. The control module 15 is preferably a microcontroller such as an Atmega 328 configured to control the drive module 12 in response to a control signal to drive the curtain 9 to be rolled up or unfolded, or to drive the blade 9 to rotate.

For the part of the remote end 20, the remote end 20 can be a portable electronic device such as a smart phone, a tablet computer, a personal digital assistant, a notebook computer, etc., and of course, it can also be a desktop computer. The remote end 20 can include an application 21 for the user to control by the application 21 to generate a control signal and transmit it to the near end 10 by wireless transmission, so that the near end 10 operates according to the user's manipulation. .

It should be particularly noted that when the control module 15 drives the curtain 9 to expand according to the control signal, the control module 15 controls the curtain 9 to be rolled up first to trigger the limit switch 11, and then the control module 15 performs a return according to the limit signal. The zero program, and then the stepping motor 121 of the control drive module 12 drives a predetermined amount of scrolling to cause the curtain to unfold to the bottom end of the scrolling stroke. Since the stepping motor 121 continues to rotate when the curtain 9 is placed from the top to the bottom, the direction of rotation of the motor is constant, but the curtain 9 will be changed from unfolded to retracted. Therefore, by setting the predetermined scroll amount, when the stepping motor 121 is required to be placed at the bottom, the control module 15 calculates the amount of scrolling, and stops if the upper limit is reached, thereby preventing the stepping motor 121 from turning over.

In addition, the above-mentioned zeroing procedure can also be used to further confirm whether the driving module 12 has fully rolled the curtain 9, and to confirm whether the limit switch 11 can operate normally, thereby ensuring that the curtain remote control system 100 can operate normally.

Please refer to FIG. 3, which is a schematic diagram of the circuit connection of the curtain remote control system of the present invention. The control module 15 is preferably a microcontroller such as an Atmega 328, and is electrically connected to the limit switch 11 , the stepping motor 121 , the strong torque motor 122 , the power supply module 13 , and the wireless transmission module 14 . The peripheral circuit of the control module 15 may include a rest circuit and a quartz oscillator. The rest circuit can be connected to an external switch to force the curtain remote control system 100 to reset. In addition, an LCD can also be connected to display information, which can be connected as shown in the figure.

Please refer to FIG. 4, which is a schematic diagram of the stepping motor driving of the curtain remote control system of the present invention. Since a larger stepping motor 121 is required to drive the window covering 9, the stepping motor 121 can be driven by a driving IC, which preferably can have four sets of NPN Darlington transistors, and has a flywheel diode, input. It can withstand a maximum current of 3 (mA), for example, the FT5754 driver IC is very suitable for driving the stepper motor 121 of the present invention. As shown in Fig. 4, the present invention uses it as a buffer to increase the supply current. The driving signal is connected to the first, fifth, eighth, and twelfth pins of the driving IC by the control module 15, and the second, fourth, ninth, and eleventh pins of the driving IC are connected to the stepping motor 121. The 3rd and 10th pins of the driver IC are connected to +5V, and the 6th and 7th pins are grounded, whereby the stepping motor 121 can be appropriately driven. Further, the strong torque motor 122 can control the blade opening of the window covering 9, which can be driven by a driving IC such as L293B. Preferably, the strong torque motor 122 can be driven by the H-bridge method, and the control module 15 can give the two control signals to achieve the forward and reverse rotation effects. For the related connection manner, refer to the strong torque motor 122 indicated in FIG. Drive circuit 1221.

The power supply module 13 can include a solar unit 131 and a power storage unit 132. The solar unit 131 is configured to receive solar energy and convert it into electrical energy, and store the electrical energy into the electrical storage unit 132, and the electrical storage unit 132 supplies the stored electrical energy to the relevant components of the remote control curtain system 100.

The power supply module 13 can adopt a maximum power point tracking method (MPPT) and a three-stage charging mode to facilitate the solar unit 131 to charge the power storage unit 132. According to the judgment principle and implementation method, the maximum power point tracking method can be roughly classified into six methods, namely voltage feedback method, disturbance observation method, incremental conductance method, actual measurement method, hybrid tracking method, and three. Point weight method; preferably, the present invention employs a perturbation observation method.

The disturbance observation method is simple and has few measurement parameters, and the calculation result is also very accurate, so it is generally applied to the maximum power point tracking of the solar cell. By periodically increasing or decreasing the size of the load, the terminal voltage and output power of the solar cell are changed, as shown in FIG.

When the output power is smaller than before the change, the output load of the system is reduced. Through repeated disturbances, observations and comparisons, the solar cells reach their maximum power point. Since the disturbance does not stop after reaching the maximum power point (Pmax), it will oscillate around the Pmax point and cause energy loss. Especially when the atmospheric environment changes slowly, the energy loss will also increase, and each time it shrinks. The magnitude of the secondary disturbance, although it can reduce the amplitude of the oscillation at the Pmax point to reduce the energy loss, but the temperature or the intensity of the sunlight changes greatly, which will increase the tracking time.

The so-called three-stage charging, the first phase is called constant current phase, the second phase is called constant pressure phase, and the third phase is called turbulent phase. The present invention employs a three-stage charging method that has a better charging curve and a longer battery life than a single constant voltage charging and constant current charging method. When the voltage of the electric storage unit 132 is lower than 14.5V, the current is charged at a constant current, and the current is maintained at 0.9A; when the voltage is greater than or equal to 14.5V, the voltage is charged to a constant voltage, and the voltage of the electric storage unit 132 is maintained at 14.5V, and the current is slow. Drop; when the current is less than 0.1A, the battery is charged to float charging, the voltage of the power storage unit 132 is maintained at 13.6V, and when the current is less than 0.03A, the charging of the battery is stopped.

The power supply module 13 can include a voltage sampling module 133 and a current sampling module 134 to form a charging circuit, as shown in FIG. The voltage sampling module 133 can include two sampling resistors respectively disposed at two ends of the voltage of the power storage unit 132 to sample the voltage value between the two sampling resistors. The ratio of the two sampling voltages can be 5:1, and the voltage value is obtained by the partial pressure formula. The current sampling module 134 can sample the current value by means of Hall current sensing and transmit it to the control module 15. The current sampling module 134 can be, for example, an IC such as the ACS 712. The basic architecture of the charging circuit can consist of a flyback. Vin terminal is the input terminal, V1 terminal is the output terminal, D1 and D2 are diodes, and current and voltage detection (voltage sampling module 133 and current sampling module 134) are provided at both ends of the circuit input and output. The control module 15 controls the output voltage by controlling the time during which the switch is turned on and off (ie, PWM-pulse width modulation). Among them, the transistor (MOSFET) requires less driving power, and the switching speed is fast, and the switch can be high frequency, which is suitable for use as a control charging and discharging switch.

When the control module 15 determines that the voltage value is equal to or larger than 1/6 of the voltage at the time of full charge of the electric storage unit 132, it is determined that the charging is stopped to the electric storage unit 132. For example, when the voltage of the power storage unit 132 is 14.5V when the battery is fully charged and the voltage value of the sampling voltage is calculated to be 2.45V, the control module 15 controls the switch and does not perform charging.

It should be noted that the control module 15, the wireless transmission module 14, and the limit switch 11 should preferably be supplied in an independent power supply mode, because the control module 15, the wireless transmission module 14, and the limit are provided. The switch 11 is connected to the power storage unit 132, and if the power storage unit 132 consumes power, the above components will be affected. At this time, if the control module 15 fails to operate, if there is another power source to be charged to the power storage unit 132, charging will not be possible. The wireless transmission module 14 and the limit switch 11 are uncontrollable by the curtain 9 portion. In addition, the power supply module 13 can be supplied to the stepping motor 121 and the strong torque motor 122 by stepping down the power to a predetermined voltage (for example, 5v) through a step-down module.

In the curtain remote control system 100 of the present invention, the communication between the proximal end 10 and the distal end 20 can be performed by means of Bluetooth transmission. When the user uses the application 21 of the remote 20 to generate a control signal, and transmits it to the near end 10 via the Bluetooth. According to the control signal, the control module 15 can control the stepping motor 121 to raise the curtain 9 to the top. After touching the limit switch 11, the internal value of the control module 15 is zeroed to ensure that the lower limit value is correct and also tested. The stepping motor 121 is strong enough to pull the curtain 9 and the limit switch 11 signal transmission is normal. At this time, the control module 15 can further control the stepping motor 121 to expand the curtain 9 to the bottom. Since there is no detection system at the bottom, the control module 15 controls the stepping motor 121 to operate according to the predetermined amount of scrolling, which can avoid rotation. Too many phenomena. In addition, according to the control signal, the control module 15 can control the operation of the strong torque motor 122, and the blades of the original curtain 9 are in a parallel state and are turned into a shaded state. That is, the rotation of the blade of the curtain 9 can be controlled by the positive rotation of the strong torque motor 122 to achieve the control of the intensity of the light in the room.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
