Description

Technical Field

[0002] In the field of automation control, traditional equipment operation mainly relies on physical buttons, infrared remote controls, and other contact-based or short-range control methods, which suffer from limited operating space and limited interaction methods. In the field of non-contact control, solutions based on visual recognition or complex gesture sensors have been applied; for example, 3D gesture recognition chips can detect 13 types of motion trajectories. However, their algorithms are complex and hardware costs are high, making them difficult to adapt to the control needs of ordinary civilian equipment. Existing wireless control technologies mostly use fixed encoding protocols and lack the ability to adaptively resolve dynamic gesture directions, resulting in high system response delays and false trigger rates.

Specifically, the use of "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] In response to the problems existing in the current technology, such as Figure 1 As shown, this utility model provides a control device 91, including a photoelectric sensing module 3, a communication module, and a microcontroller 6. The photoelectric sensing module 3 and the communication module are electrically connected to the microcontroller 6. The photoelectric sensing module 3 and the microcontroller 6 cooperate to identify the movement direction of the sensed object. The microcontroller 6 communicates with an electronic device 92 through the communication module, enabling the electronic device 92 to perform automated operations. It can identify two directions of hand or object movement, i.e., left and right or up and down, and transmit corresponding directional control codes to the electronic device through the communication module within the device. This not only reduces the cost of the control device but also has a short response delay and a low false trigger rate. Preferably, the communication module is a wireless communication module.

[0036] In some embodiments, the electronic device 92 is a roller shutter, an electric door, or a lighting fixture, and the automated operation includes operations such as opening, stopping, and closing. For example, when the electronic device 92 is a lighting fixture, opening means starting the lighting fixture and putting it into working condition; stopping means pausing the current operation (such as temporarily freezing the dimming mode or dynamic lighting effects); and closing means cutting off the power supply and terminating the operation of the lighting fixture.

[0037] In some embodiments, the photoelectric sensing module 3 includes a first photoelectric sensing switch, a second photoelectric sensing switch, and a third photoelectric sensing switch arranged sequentially in a set direction; the first photoelectric sensing switch, the second photoelectric sensing switch, and the third photoelectric sensing switch are respectively electrically connected to the microcontroller 6.

[0038] In some embodiments, the set direction is from top to bottom; and / or the first photoelectric sensor switch, the second photoelectric sensor switch, and the third photoelectric sensor switch are respectively connected to the I / O pins of the microcontroller 6 as photoelectric input signals of the microcontroller 6 for identifying the movement direction of the sensed object.

[0039] For example, the photoelectric sensing module 3 includes three photoelectric sensing switches arranged in a top-middle-bottom configuration: a first photoelectric sensing switch, a second photoelectric sensing switch, and a third photoelectric sensing switch. Their output pins output corresponding signal outputs A, B, and C, respectively. When there is no object obstructing the sensing area of ​​a photoelectric sensing switch, its signal pin has no output; when an object obstructs the area, it outputs the corresponding signal. These three signals are connected to the I / O pins of the microcontroller 6, serving as photoelectric input signals for the microcontroller 6 to recognize and calculate object-sensing gestures within the area of ​​the photoelectric sensing module 3. When the object is not in the sensing area, none of the three signals are output; when the object enters the sensing range of photoelectric input 1 in the sensing area, signal A is output; when the object enters the sensing range of the first and second photoelectric switches in the sensing area, signal A and signal B are output simultaneously; when the object enters the sensing range of the first, second, and third photoelectric switches in the sensing area, signal A, signal B, and signal C are output simultaneously; when the object leaves the first photoelectric switch in the sensing area but remains within the sensing range of the second and third photoelectric switches, signal B and signal C are output; when the object leaves photoelectric input 1 and photoelectric input 2 in the sensing area but remains within the sensing range of photoelectric input 3, signal C is output; when the object leaves photoelectric input 3 in the sensing area, none of the three signals are output. At this time, the microcontroller 6 calculates the output sequence of the signals just collected to determine whether the recognition is valid and calculates the direction.

[0040] Based on the above, the logical sequence of the three photoelectric signal outputs is A->AB->ABC->BC->C->None. From this signal sequence, the process can be calculated as a "top-down" movement. If this process is predefined as a "closing" operation, the microcontroller 6 transmits a "closing" data code through the wireless transmission module 5 to close the door or shut down the appliance. The same logic applies to a "bottom-up" movement process.

[0041] When the sensed object (hereinafter referred to as "the object") is stationary, the entire signal process output is as follows:

[0042] When the sensed object remains within the sensing range of any two or more photoelectric inputs without any movement or change, and the holding time reaches 0.5 seconds or more, the main control microcontroller 6 interprets this operation as a "stop" operation. The main control microcontroller 6 then transmits a "stop" data code through the wireless transmission module 5, thereby controlling the external door controller to perform a stop action. It is worth noting that the above calculation process is well-known to those skilled in the art, and this utility model does not involve any improvement to the computer software.

[0043] In some embodiments, the communication module includes a wireless transmission module 5, which is electrically connected to the microcontroller 6. The microcontroller 6 communicates with the electronic device 92 through the wireless transmission module 5. For example, the wireless transmission module 5 is used to transmit wireless data at a 433MHz carrier frequency. When the microcontroller 6 detects a hand or object sensed by the photoelectric sensor 3 and calculates the effective sensing direction, it sends out the corresponding wireless data signal according to the defined correspondence between the direction and the "on, off, off" wireless data signal to control the electronic device 92 and realize the on, off, and off operations of the appliance.

[0044] In some embodiments, the device further includes a setting button 2; the setting button 2 is electrically connected to the microcontroller 6 and is used to control the microcontroller 6 to enter the setting state.

[0045] In some specific embodiments, the communication module further includes a wireless receiving module 4; the wireless receiving module 4 is electrically connected to the microcontroller 6 and is used to receive external commands after the microcontroller 6 enters the setting state, in conjunction with the setting button 2. For example, the wireless receiving module 4 is used to receive wireless data at a 433MHz carrier frequency. Before the device operates, the setting button 2 is used to put the device into the setting state, and then the three wireless data signals of "on," "off," and "off" are transmitted to the microcontroller 6 through the receiving module. The microcontroller 6 saves these three data signals.

[0046] In some embodiments, the device further includes a battery 7 and a step-down voltage regulator module 8; the battery 7 supplies power to the microcontroller 6 through the step-down voltage regulator module 8.

[0047] In some embodiments, the device further includes an indicator light 1; the indicator light 1 is electrically connected to the microcontroller 6 and is used to indicate the working status.

[0048] like Figure 2As shown, based on the above-mentioned control device 91, the present invention also provides an automated control system 9, including the control device 91 and an electronic device 92; the control device 91 communicates with the electronic device 92 so that the electronic device 92 performs automated operations.

[0049] In some embodiments, the electronic device 92 is a roller shutter, an electric door, or a light fixture.

[0050] Although the embodiments of this utility model have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of this utility model as described in the claims. Moreover, the utility model described herein may have other embodiments and can be implemented or realized in various ways.
