working principle:

The present invention includes a transmission device and a control device, wherein the control device includes an automatic control device and a remote control device. The function of the transmission device is to drive the synchronous belt pulley through the forward rotation of the motor to drive the synchronous belt to move, and the synchronous belt drives the inner fixed pulley hook and the outer fixed The pulley moves from the middle to the left end and the right end of the chute, so that the curtain can be opened. On the contrary, the closing of the curtain is realized; the automatic control module adopts TSL2560 light intensity sensor to sense the external light intensity, and transmits the signal to the single chip microcomputer for processing and then controls the motor to work, so as to realize the automatic opening and closing of the curtain; the remote control module mainly sets the corresponding function through the matrix keyboard of the remote control module The operation initiates a corresponding interrupt request to the single-chip microcomputer. After the interrupt response is completed, the motor realizes forward or reverse rotation, thereby realizing the opening and closing of the curtain.

The switch of the curtain device can realize the functions of "manual remote control" and "automatic control", but the processing priority of "manual remote control" is higher than that of "automatic control". That is, no matter when the curtain is in the state of opening or closing, the desired state can be realized by the remote controller.

During remote control, when the curtain is closed, manually press the button on the remote control to open, at this time, the single-chip microcomputer processing makes the control motor rotate forward, so that the fixed pulley hook moves to the left and right ends of the chute through the synchronous belt movement, so that The curtain realizes the function of opening; when the curtain is in the open state, manually press the button on the remote control to close, at this time, the control motor is reversed through the processing of the single-chip microcomputer, so that the fixed pulley hook moves to the middle of the chute through the movement of the synchronous belt, so that the curtain can be realized. Disabled functionality.

During automatic control, the single-chip microcomputer judges whether the light intensity value collected by the light intensity sensor is within the preset indoor light intensity range. If not, it controls the motor to rotate to realize the slow automatic opening or closing of the curtains, and continuously detects the indoor light intensity at the same time. The value of the intensity, until the detected light intensity value is within the specified range or the curtain has been completely opened or closed, the engine stops rotating. With the continuous change of indoor light intensity, the opening size of the automatic curtain is also constantly changed to control the indoor light intensity within a certain range. And the opening degree of automatic curtain is determined the opening degree situation of curtain at this moment by the time that single-chip microcomputer records engine forward and reverse, so just no longer need other sensors to detect the position of curtain. Different modes can be selected through the remote control, and different threshold ranges can be set in the automatic mode.

The beneficial effects of the present invention are as follows:

1. This design is an innovative automatic curtain with simple structure and powerful function. It can not only realize the simple remote control switch function, but more importantly, it can automatically realize the arbitrary opening of the curtain and intelligently adjust it according to the change of the indoor light intensity. Indoor light intensity, simple structure, convenient installation and operation, improve living comfort, and can meet people's needs for high-quality life.

2. The transmission device adopts synchronous belt transmission, which has low noise, low cost and easy maintenance.

When the automatic control mode is turned on, three working modes are provided for the user to choose: low light mode, normal mode, and high light mode. Each mode has two thresholds: low threshold and high threshold. The indoor light intensity is sensed in real time by the light intensity sensor. When the indoor light intensity is between the low threshold and the high threshold, the curtain is in a stable state; when the indoor light intensity is less than the low threshold, the microcontroller first judges whether the curtain is fully Open, if it has been fully opened, the motor 6 will not work to prevent damage to the device; if it is not fully opened, the motor 6 will start to rotate forward, and slowly open the curtain through the timing pulley 8, timing belt 7 and fixed pulley hooks 9, 10 , and at the same time detect whether the indoor light intensity is higher than the low threshold, if it is higher, the curtain will stop opening, otherwise it will continue to open until the curtain is fully opened; when the indoor light intensity is higher than the high threshold, the microcontroller first judges whether the curtain has been opened Completely closed, if it is completely closed, the motor 6 does not work to prevent damage to the device; if it is not completely closed, the motor 6 starts to reverse, and it is slowly closed through the timing belt pulley 8, the timing belt 7 and the fixed pulley hook 9, 10 Curtains, and at the same time detect whether the indoor light intensity is lower than the high threshold, if it is lower than the high threshold, the curtain will stop closing, otherwise it will continue to close until the curtain is completely closed. (Low light mode is suitable for weather or seasons with relatively dark light; general mode is suitable for weather and seasons with average light intensity such as spring and autumn, and low light mode is suitable for weather or seasons with strong light such as sunny days and summer. The specific threshold value is set by Obtained from measurement experiments with different light intensities such as cloudy and rainy days, normal days, and sunny days.)

When someone controls, as shown in Figure 6, turn on the manual control button of the remote control, and the processing priority of "manual remote control" is higher than that of "automatic control". Press the corresponding switch on the remote control, send a control signal through the infrared controller, transmit it to the infrared receiving module, and then transmit the obtained signal to the single-chip control center STC89C52 for processing, send a response signal to the motor and control the forward and reverse rotation of the motor to realize Curtain switch.
