Network monitoring function of status information and statistics of power consumption and power limitation.

Most of the lighting equipment, electrical appliances, equipment, and other electrical devices are turned on, off, switched, or moved, usually using a set of switches. Traditionally, switches have buttons, knobs, knobs, push buttons and other machinery. This type of mechanical design has a structure that protrudes from the surface of the control panel. It cannot be matched with the existing technology-oriented device or built-in, which destroys the overall aesthetics of the appearance of the device using the switch. Furthermore, the mechanical contact switch There is a contact spark phenomenon during operation, and there is a danger of detonating gas or flammable gas. The switching of these switches is to use the internal reed as the switching switch and positioning. When used for a long time, the reed will produce elastic fatigue and cause poor contact, or the contact metal surface oxidation will cause the contact resistance value to increase and consume energy. , Accelerating the temperature to cause an accidental fire, and the danger of leakage or accidental electric shock due to humidity.

In recent years, due to the advancement of science and technology, the application of touch technology has been generally developed on many devices. For example, the touchpad has become the most important application technology at present, and the touchpad touch technology includes resistive, capacitive, and inductive , Optical, etc., and capacitive touch technology has the characteristics of durability, low cost, etc., and has gradually become the preferred technology for touch. The current touchpad capacitance values when touched and not touched are often very similar. It is necessary to add complex and real-time calculations and respond quickly to prevent the device from being affected by the external environment, which may cause misjudgment. .

In other words, how to simultaneously solve the problems of the conventional mechanical damage to the overall appearance, short service life, and the misjudgment of sensing keys caused by environmental changes caused by capacitive touch switches are important issues in the industry. In addition, the traditional technology touch switches do not have the function of networking control, and cannot use networking to control multiple touch switches arranged in a large area, which affects the convenience and expandability in practical applications.

Therefore, there is a great need for a non-contact networked switch system with self-calibration, which uses a garbled generator and a modulation circuit to prevent malfunction, and uses signal transmission and reception to cooperate with a remote control device to implement networked control, thereby solving the problems of the above-mentioned conventional technology.

The main purpose of the present invention is to provide a non-contact networked switch system with self-calibration, which includes a remote control device, multiple signal transceivers, multiple controlled devices, and multiple non-contact induction switches for providing such control objects. The non-contact induction switches control the electrical operation of the controlled devices respectively. At the same time, the remote control device can generate and send control signals to the signal transceivers to directly control the electrical control of the controlled devices. operating. In particular, a non-contact induction switch is connected to a controlled device and senses a corresponding control object in a non-contact manner, thereby controlling the electrical operation of the controlled device. In addition, different signal transceivers can mutually forward the received control signals and the usage status information of the controlled device, so that the remote control device can control and grasp the operation status and power consumption statistics of each controlled device, thereby achieving All, group or individual action switches or networking functions that transmit usage status information.

The above non-contact induction switch can reflect the infrared rays emitted by the non-contact induction switch within a fixed distance when the control object is close to the non-contact induction switch. After receiving the correct signal, the non-contact induction switch transmits an operation signal to the external The controlled device provides a non-contact induction switch function of the controlled object to the controlled device. The non-contact inductive switch of the present invention includes a controller and a control interface, wherein the controller sends a modulation signal to the control interface, and the control interface emits infrared rays outward according to the modulation signal, and the infrared rays are reflected to the control interface through the control object, and the control interface is based on The received infrared ray returns a return signal to the controller, and the controller processes the received return signal, and generates an operation signal if it is determined to be correct.

The controller includes an irregular signal generator, a garbled generator, a modulation circuit, a demodulation circuit, a comparator, a signal transmitter, and a self-calibration unit, and the control interface further includes a substrate, an infrared transmitter and an infrared receiver, of which infrared The transmitter and the infrared receiver are located on the inner side of the substrate, and the substrate is made of an infrared-transmissive material, and the infrared transmitter and the infrared receiver are electrically connected to the self-calibration unit, respectively. In particular, after the system is started, such as turning on the power, the unscheduled signal generator automatically generates signals from time to time and sends them to the garbled code generator. After the garbled code generator receives the signals, it re-encodes the signals to form a coded signal, and the coded signal is simultaneously transmitted to the comparator and adjusted. Transformer circuit. The modulation circuit receives the encoded signal, sends out the modulation signal after being modulated, and receives it from the self-calibration unit, and generates and transmits a driving signal. The self-calibration unit implements a self-calibration function by performing a self-calibration process.

The self-calibration unit transmits the driving signal to the infrared transmitter of the control interface. The infrared transmitter receives the modulation signal and emits infrared rays and penetrates the substrate. When the control object on the other side of the substrate approaches, and reflects the infrared rays within a fixed distance. After passing through the substrate to the infrared receiver, the infrared receiver generates and transmits the sensing signal to the self-calibration process in the controller. The self-calibration process generates and transmits a return-back signal to the demodulation circuit according to the sensing signal, and the demodulation circuit receives the return-back signal and demodulates it to a comparison signal and sends it to the comparator.

The comparator compares the encoded signal and the demodulated comparison signal from the garbled generator. If the encoded signal and the comparison signal are the same after comparison, the comparator will send a control signal to the signal transmitter, and the signal transmitter Send operation signals to external controlled devices according to control signals. If the coded signal and the comparison signal are different, it is considered that no sensing action does not generate a control signal, which means that the non-contact sensing switch is not triggered by the control object.

Furthermore, the self-calibration process of the self-calibration unit gradually increases the intensity of the driving signal to change the intensity of the sensing signal, and determines whether the intensity of the sensing signal reaches a preset value. If the intensity of the sensing signal has reached a preset value, stop increasing the intensity of the driving signal and fix the intensity of the driving signal. If the strength of the sensing signal does not reach the preset value when the strength of the driving signal reaches the maximum value, the self-calibration unit generates and transmits an abnormal warning signal for notifying the user.

The invention further comprises an LED indicator light, which is located on the same side as the infrared transmitter and the infrared receiver, is continuously illuminated by the power source and the light passes through the substrate, so that the operator on the other side of the substrate can see the bright light, especially The position and operation state of the non-contact induction switch of the present invention can be clearly displayed in the dark.

The invention utilizes a remote control device to generate and transmit control signals, and directly controls the electrical operation of the controlled device via a signal transceiver, and different signal transceivers can actively forward the received control signals to each other and the use of the controlled device. The status information enables the remote control device to control and master each controlled device to achieve all, group or individual action switches or networking functions that transmit status information. Furthermore, the non-contact induction switch uses a random code generator to generate a coded signal in a random manner and the modulation circuit modulates the coded signal, avoiding a specific frequency range, and greatly reducing the chance of misoperation through the above two levels. In addition, the use of infrared transmitters and infrared receivers can also be distinguished from electromagnetic waves in daily life, again avoiding misoperation.

Please refer to the first figure, which is a schematic diagram of a non-contact networked switch system with self-calibration according to an embodiment of the present invention. As shown in the first figure, the non-contact networking switch system with self-calibration according to the embodiment of the present invention includes a plurality of non-contact induction switches 1, a plurality of control objects 2, a plurality of controlled devices 3, a remote control device RC, and Multiple signal transceivers TR are used to provide the control objects 2 to control the electrical operations of the controlled devices 3 via the non-contact induction switches 1 respectively. At the same time, the remote control device RC can generate and transmit control signals to The signal transceivers TR are used to directly control the electrical operation of the controlled devices 3. That is, in the non-contact networking switch system, the controlled device 3 can be controlled by the control object 2 or the remote control device RC. In particular, each non-contact inductive switch 1 is a non-contact inductive corresponding control object 2, and each controlled device 3 is electrically connected to a corresponding non-contact inductive switch 1. At the same time, each signal transceiver TR is The electrical connection corresponds to the controlled device 3. In addition, the remote control device RC is wirelessly connected to the signal transceivers TR.

The above-mentioned control object 2 may be a finger, a card, a pen, or other objects that can reflect infrared rays, and the controlled device 3 may be an electric light, a security start system, air-conditioning, a door lock, an electric curtain, an elevator floor key, a vending machine selection key , Doorbell, etc.

Specifically, the non-contact induction switch 1 is projected to the control object 2 by emitting infrared rays and reflected by the control object 2. When the control object 2 approaches and is within a fixed distance of the transmission, the non-contact induction switch 1 can receive the The infrared light reflected by the control object 2 activates the external controlled device 3, so the present invention essentially provides the control object 2 to switch the controlled device 3 on and off. In particular, the control object 2 does not contact the non- The contact induction switch 1 achieves the non-contact induction control function.

In addition, the signal transceivers TR can actively forward the received control signals and the use status information of the controlled device 3 to each other, as compared with the open or closed use status. Therefore, when a certain signal transceiver TR receives a control signal, it can transmit the control signal to the adjacent or all signal transceivers TR. At the same time, the use status information of each controlled device 3 can also be used in this way. And it is transmitted to all signal transceivers TR, and to the remote control device RC, so that the remote control device RC can grasp the use status information of each controlled device 3, so as to achieve all, group or individual actions of switching or transmission Networking capabilities that use status information.

Next, referring to the second figure, a schematic diagram of a non-contact induction switch in the present invention. Specifically, the non-contact induction switch 1 includes a controller 10 and a control interface 20, and the controller 10 sends a modulation signal S1 to the control interface 20, and the control interface 20 emits infrared rays according to the modulation signal S1. In addition, The infrared rays are reflected to the control interface 20 through the control object 2 so that the control interface 20 can return a loopback signal S3 to the controller 10 according to the received infrared rays. At the same time, the controller 10 processes the received loopback signal S3 and generates an operation. The signal S5 is transmitted to the controlled device 3.

The controller 10 includes an irregular signal generator 11, a garbled generator 12, a modulation circuit 13, a demodulation circuit 14, a comparator 15, a signal transmitter 16, and a self-correction unit 17. When the system is started, such as turning on the power, the unscheduled signal generator 11 automatically generates a signal to the garbled code generator 12 at random. After receiving the signal, the garbled code generator 12 re-encodes the signal to form a coded signal, and the coded signal is simultaneously transmitted to the comparator. 15 和 modulation circuit 13. The modulation circuit 13 converts the encoded signal into a modulation signal S1 and transmits it to the self-calibration unit 17, and the self-calibration unit 17 generates and transmits a driving signal S1D according to the modulation signal S1.

The control interface 20 includes a substrate 21, an infrared transmitter 23, and an infrared receiver 25. The infrared transmitter 23 and the infrared receiver 25 are located inside the substrate 21, and the substrate 21 is made of a material that can transmit infrared rays. The infrared transmitter 23 and the infrared receiver 25 are electrically connected to the self-calibration unit 17 of the controller 10, respectively. The infrared transmitter 23 receives the driving signal S1D, and emits infrared rays and penetrates the substrate 21. When the control object 2 located on the other side of the substrate 21 approaches and is within a fixed distance of emission, the control object 2 reflects infrared rays and penetrates the substrate 21 to project to the infrared receiver 25, so that the infrared receiver 25 generates a sensing signal S3R, And return to the self-calibration unit 17. The self-calibration unit 17 generates a loopback signal S3 according to the sensing signal S3R and transmits it to the demodulation circuit 14 in the controller 10. The demodulation circuit 14 receives the echoed-back signal S3, demodulates it into a comparison signal, and transmits it to the comparator 15.

The comparator 15 compares the coded signal transmitted from the garbled code generator 12 with the demodulated comparison signal. If the coded signal and the comparison signal are the same after comparison, the comparator 15 will send a control signal to the signal transmitter 16, The signal transmitter 16 sends the operation signal S5 to the external controlled device 3 according to the control signal. If the coded signal and the comparison signal are different, it is considered that no sensing action does not generate a control signal, which means that the non-contact sensing switch 1 is not triggered by the control object 2.

Specifically, the garbled code generator 12 generates a coded signal in a random manner, so that the coded signals generated within a period of time are different from each other, which can prevent misoperation. For example, the garbled generator 12 can generate a total of 1000 coded signals, A1 ~ A1000, and randomly generate 5 coded signals over a period of time, A52, A2, A632, A100, A5. The comparator 15 receives the demodulation and demodulation by the demodulation circuit 14. After comparing the comparison signal with the encoded signal, if they are the same, the control signal is transmitted to the signal transmitter 16; if they are not the same, it is regarded as a non-inductive action and no control signal is generated. After the encoded signal is converted by the modulation circuit 13, the set frequency range can be avoided, and the probability of misoperation is reduced again.

In particular, the self-calibration unit 17 described above implements a self-calibration function by performing a self-calibration process. The self-calibration process mainly changes the intensity of the sensing signal S3R by gradually increasing the intensity of the driving signal S1D, and further determines whether the intensity of the sensing signal S3R has reached a preset value, and if the intensity of the sensing signal S3R has reached a preset value , Stop increasing the intensity of the driving signal S1D, and fix the intensity of the driving signal S1D, and if the intensity of the driving signal S1D has reached the maximum value, but the intensity of the sensing signal S3R has not reached the preset value, the self-correcting unit 17 generates and transmits an abnormal warning signal SA, and the abnormal warning unit 4 receives the abnormal warning signal SA and displays an abnormal message to notify the user. Preferably, the abnormality warning unit 4 may include an LED or a buzzer, and the abnormality message may include an LED flashing light or a buzzer sound.

In addition, the control interface 20 of the non-contact inductive switch 1 of the present invention may further include an LED indicator 27, which is located on the same side as the infrared transmitter 23 and the infrared receiver 25, and is continuously illuminated by the power source, and the light can pass through. The operator passes through the substrate 21 so that the operator on the other side of the substrate 21 can see the bright light, especially the position of the non-contact induction switch 1 of the present invention can be clearly displayed in the dark. It should be noted that the LED indicator 27 can be combined with the abnormality warning unit 4 to form a single element, which further simplifies the overall structure.

Further referring to the third figure, one of the application examples of the non-contact induction switch 1 of the present invention. The substrate 21 includes a control interface 20 and a controller 10 for controlling the controlled device 3. The LED indicator light 27 emits LED light to indicate the switch position, so that the operator can know exactly where to operate the switch without a light source. When the system is started, the unscheduled signal generator 11 in the controller 10 automatically generates signals to the garbled generator 12 from time to time. After receiving the signals, the garbled generator 12 re-encodes the signals to form encoded signals, and the encoded signals are transmitted to the comparator at the same time. 15 和 modulation circuit 13. The modulation circuit 13 converts the encoded signal into a modulation signal S1 and sends it to the infrared transmitter 23. The infrared transmitter 23 emits infrared rays outward and penetrates the substrate 21. When the control object 2 is close to the control interface 20 and within a fixed distance of the transmission At this time, the infrared rays emitted by the infrared transmitter 23 are reflected to the infrared receiver 25. After demodulation by the demodulation circuit 14 in the controller 10 and comparison by the comparator 15, if it is the same signal, it further sends an operation signal S5 to the controlled device 3 to perform an on or off action; if it is not the same, it is regarded as a non-inductive action .

In the fourth diagram of the present invention, the non-contact induction switch 1 includes two sets of control interfaces 20, two sets of infrared transmitters 23, two sets of infrared receivers 25, and two sets of LED indicators 27 on the substrate 21, and two sets of control interfaces 20 is electrically connected to the same controller 10, and the controller 10 is additionally electrically connected to two different controlled devices 3. Further, the two sets of control interfaces 20 are used to control different controlled devices 3, and the LED indicator light 27 can use different colors to represent that the control interface 20 is to control different controlled devices 3, so that the operator can operate even in the absence of a light source. Nor does it confuse the switch position.

When the system is started, the unscheduled signal generator 11 in the controller 10 automatically generates signals to the garbled generator 12 at random. After receiving the signals, the garbled generator 12 re-encodes the signals to form encoded signals, and the encoded signals are transmitted to the comparator at the same time. 15 和 modulation circuit 13. The modulation circuit 13 converts the encoded signal into a modulation signal S1 and sends it to two sets of infrared transmitters 23. The two sets of infrared transmitters 23 then emit infrared rays and penetrate the substrate 21, and when the control object 2 approaches one of the control interfaces 20 and When transmitting within a fixed distance, the infrared radiation emitted by the infrared transmitter 23 is reflected to the infrared receiver 25. The infrared receiver 25 returns the return signal S3 to the demodulation circuit 14 in the controller 10. The demodulation circuit 14 demodulates the return signal S3 to form a comparison signal, and transmits the comparison signal to the comparator 15.

The comparator 15 compares the coded signal transmitted from the garbled code generator 12 with the demodulated comparison signal. If the coded signal and the comparison signal are the same after comparison, the comparator 15 will send a control signal to the signal transmitter 16, The signal transmitter 16 sends the operation signal S5 to the external corresponding controlled device 3 according to the control signal. If the encoding signal and the comparison signal are not the same, it is regarded as no induction operation and no control signal is generated.

In order to further explain the characteristics of the garbled signal generated by the garbled generator in the non-contact induction switch of the present invention, please refer to the fifth figure. As shown in the fifth figure, the garbled generator 12 may include a microcontroller (MCU) 40, a first counter 41, a second counter 42, a divider 43, a plurality of mutually exclusive OR gates (XOR) 44, and a shifter 45. It should be noted that the hardware structure of the garbled generator 12 in the fifth figure is only an exemplary example for facilitating the description of the features of the present invention, and is not intended to limit the scope of the present invention, that is, other garbled signals that generate garbled signals The generator should also be included in the present invention.

Specifically, the microcontroller 40 generates a plurality of clock signals, including a first clock signal CK1, a second clock signal CK2, and a third clock signal CK3, and sends them to the first counter 41, the divider 43, and the shifter 45, respectively. The first clock signal CK1, the second clock signal CK2, and the third clock signal CK3 may be the same clock signal, or may be clock signals with different frequencies.

The first counter 41 and the second counter 42 may be composed of K-bit counters, where K is a positive integer and the number of the exclusive OR gate 44 is K, which is used to match the first counter 41 and the second counter 42. In addition, the shifter 45 may be a K-bit shifter, and an 8-bit counter is used to implement the first counter 41 and the second counter 42 in the figure. The 8-bit shifter 45 is used as an exemplary example. Furthermore, the divider 43 may be a divider that divides n, where n is a positive integer greater than 1.

The first counter 41 counts after receiving the first clock signal CK1, and transmits the counting result to the corresponding exclusive OR gate 44. The divider 43 receives the second clock signal CK2 for frequency division and generates a frequency division result, and transmits it to the second counter 42, and the second counter 42 counts according to the frequency division result, and the count result is further transmitted to the corresponding mutex. Or gate 44. Each mutex OR gate 44 performs an exclusive OR operation on the count results from the first counter 41 and the second counter 42, and transmits the calculation results to the shifter 45. Finally, the shifter 45 receives and generates the required encoded signal in a tandem manner from the operation result of each mutex or gate 44 according to the third clock signal CK3, and outputs it through the output terminal Qout.

It should be noted that, in this example, the bits of the first counter 41 and the second counter 42 are connected to each mutually exclusive OR gate 44 such that the low bit Q0 to the high bit Q7 of the first counter 41 correspond to the first bit in order. The high-order bit Q7 to the low-order bit Q0 of the second counter 42 are only one of the implementation methods, as long as the low-order bit Q0 to the high-order bit Q7 of the first counter 41 do not correspond to the low-order bit Q0 to high of the second counter 42 in sequence. Bit Q7 is sufficient, because the required encoding signal generated by the shifter 45 can have garbled effect.

The non-contact induction switch of the present invention uses a random code generator to generate a coded signal in a random manner and the modulation circuit modulates the coded signal, avoiding a specific frequency range, and greatly reducing the probability of misoperation through the above two checkpoints. In addition, the use of infrared transmitters and infrared receivers can also be distinguished from electromagnetic waves in daily life, again avoiding malfunctions.

In summary, the present invention is characterized by using a control object to make a non-contact induction switch control the electrical operation of a controlled device in a non-contact induction manner. In particular, the controller of the non-contact induction switch includes a garbled generator. And a modulation circuit, in which the garbled generator encodes the received signal in a random manner so that the encoded signal generated by the garbled generator does not repeat for a period of time, and the encoded signal is then transmitted to the modulation circuit. The coded signal is further modulated into a modulated signal, and the frequency range of the coded signal is changed. Therefore, the frequency range to be avoided can be set according to the environment of the non-contact induction switch. After passing through the garbled generator and the modulation circuit, The signal is emitted from the infrared emitter through the substrate. In addition, the present invention selects to transmit and receive signals in an infrared manner, so it is different from the frequency of electromagnetic waves commonly used in ordinary life, and will not interfere with each other. In particular, coupled with the dual modulation of the original signal encoding, it can further avoid misoperation. Generated to improve overall operational reliability.

Another feature of the present invention is that the remote control device is used to generate and transmit control signals to the signal transceiver and directly control the electrical operation of the controlled device. In particular, different signal transceivers can actively forward the received control signals to each other and The use status information of the controlled device enables the remote control device to control and grasp each controlled device, thereby achieving all, grouping or individual action of the switch or the networking function of transmitting the use status information.

Furthermore, the present invention can simultaneously solve the problems of traditional mechanical damage to the overall appearance, short service life, and the misjudgment of sensing keys caused by environmental changes caused by capacitive touch switches. The non-contact induction switch of the present invention can be installed in a wall. Must be light-transmitting and infrared-transmitting materials, or light-transmitting and infrared-transmissive materials are combined with each other, and the substrate can be further patterned, and the function of the switch can be clearly indicated by LED light irradiation. The switch is not directly contacted and has a long service life.

The above are only used to explain the preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Therefore, any modification or related to the present invention made in the same spirit of the invention Changes should still be included in the scope of the present invention.
