Description
Technical Field
The application relates to the technical field of intelligent switches, in particular to an intelligent switch system and an intelligent home system.
Background
The traditional two-wire system intelligent switch utilizes weak leakage current of a lamp load in a closed state of the lamp load to convert the weak leakage current into power supply in the two-wire system switch to supply power to the control module and the wireless communication module for working. The leakage current flowing through the lamp load cannot be too large, otherwise the lamp load will have abnormalities such as slight brightness and flicker, and especially Light-Emitting Diode (LED) lamps with power below 5W are particularly obvious. Therefore, in the closed state, the working currents of the internal control unit and the wireless transceiver unit of the two-wire intelligent switch connected in series with the load lamp are very limited. In addition, the traditional two-wire system intelligent switch utilizes the chopping shunt electricity taking of periodic alternating current in the on-state of the lamp load, the power source obtained inside the two-wire system switch is limited by the lamp load power and cannot be too large, otherwise, the power source inside the two-wire system switch works in a current limiting mode, and when an LED lamp load with the power below 5W is used, the power obtained by the on-state power supply circuit is very small, so that the switch is unstable in working.
The existing solution is to connect capacitors in parallel at two ends of the lamp load to provide a large current for the two-wire switch, but the capacitance value of the capacitors cannot be too large, the current provided by the capacitors is still very limited, and the power consumption of the two-wire switch is also limited. If the capacitance is too large, the alternating current impedance is very small, which is equivalent to connecting a small resistor in parallel with a load lamp, the normal work of the lamp can be influenced, the power consumption can be increased, and the volume of the large capacitance is also very large.

It should be apparent that the described embodiments are only some embodiments of the present application, and not all embodiments.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1 and fig. 2, an intelligent switch system 100 is provided in an embodiment of the present disclosure, the intelligent switch system 100 includes a load 10, an intelligent switch 30, and a switch adapter 50, and the intelligent switch 30 and the switch adapter 50 cooperate to control the on and off of the load 10.
The load 10 is arranged in an alternating current circuit, for example the load 10 may be connected between neutral and live. The load 10 may be a lamp such as an energy saving lamp or an LED lamp.
The smart switch 30 is connected in series with the load 10. The intelligent switch 30 is used for controlling the working state of the load 10, for example, when the intelligent switch 30 is turned on, the load 10 is in the working state; for example, when the smart switch 30 is turned off, the load 10 is in the non-operating state. The working state and the non-working state of the load 10 are different according to the type of the load 10, for example, if the load 10 is a lamp such as an energy saving lamp or an LED lamp, the load 10 is in the working state when lit, and is in the non-working state when the load 10 is extinguished.
The switch adapter 50 is connected in parallel with the load 10, for example, the switch adapter 50 may be connected across the load 10. The switch adapter 50 is used to detect the operating state of the load 10. The switch adapter 50 is turned on when the load 10 is in a non-operating state, so that the load 10 can be short-circuited, and thus even when the rated power of the load 10 is low, the current generated by the intelligent switch 30 does not affect the load 10, which is helpful for avoiding the occurrence of abnormalities such as slight brightness and flicker of the load 10 such as a lamp.
The switch adapter 50 may be switched on or off depending on the voltage across the load 10. For example, referring to fig. 3, the switch adapter 50 may include a voltage detection circuit 51, a first control circuit 53, and a first switch 55. The voltage detection circuit 51 is connected to the load 10. The voltage detection circuit 51 is configured to detect a voltage across the load 10 and output a voltage detection signal. The voltage detection signal is used to determine the operating state of the load 10. Because the voltage detection signal is larger when the load 10 is in the operating state, and is smaller or zero when the load is in the non-operating state, when the voltage detection signal is located in the first voltage interval, it can be determined that the load 10 is in the operating state, and when the voltage detection signal is located in the second voltage interval, it can be determined that the load 10 is in the non-operating state, where there is no intersection between the second voltage interval and the first voltage interval, and any value in the second voltage interval is smaller than any value in the first voltage interval. Thus, the state of the load 10 can be quickly determined according to the magnitude of the voltage detection signal. The first voltage interval and the specific range of the first voltage interval can be selected according to the actual product.
The first control circuit 53 is connected to the voltage detection circuit 51. The first control circuit 53 is configured to receive the voltage detection signal to output a first switching signal. The first switching signal includes a first on signal, and the first control circuit 53 outputs the first on signal when it is determined that the load 10 is in the non-operating state according to the voltage detection signal. The first switch 55 is connected to both ends of the load 10, and a control end of the first switch 55 is connected to the first control circuit 53. The first switch 55 is configured to be turned on to short-circuit the load 10 when receiving the first turn-on signal. In addition, the first switching signal may further include a first off signal, and the first control circuit 53 outputs the first off signal when it is determined that the load 10 is in the operating state according to the voltage detection signal. The first switch 55 is configured to open upon receiving a first open signal. The first switch 55 may be a relay, a MOS transistor, or a thyristor.
Referring to fig. 4, the intelligent switch 30 may include a second switch 31 and a second control circuit 33, wherein the second switch 31 is connected in series with the load 10. The second control circuit 33 is connected to the control end of the second switch 31, and the second control circuit 33 is used for controlling the switching state of the second switch 31 to control the working state of the load 10. The second switch 31 may be a relay, a MOS transistor, or a thyristor.
In addition, when the load 10 is in the working state, since the working state of the switch adapter 50 is opposite to the working state of the smart switch 30, the power supply time distribution between the smart switch 30 and the load 10 is adjusted, the energy consumption of the smart switch 30 is reduced, and the adaptability of the load 10 is improved.
Referring to fig. 3 and 4 together, the switch adapter 50 and the intelligent switch 30 can cooperate through zero-crossing points of current. For example, the switching adapter 50 may further include a first zero-crossing detection circuit 57, the first zero-crossing detection circuit 57 being connected to the load 10. The first zero-crossing detecting circuit 57 is configured to detect a zero-crossing point of a current of the load 10 according to the first threshold voltage when the load 10 is in an operating state, and output a first zero-crossing synchronizing signal. The first control circuit 53 is also connected to a first zero-crossing detection circuit 57. The first control circuit 53 is configured to receive the first zero-crossing synchronization signal when the load 10 is in the operating state, so as to output a first switching signal to the first switch 55.
The smart switch 30 may further include a second zero-crossing detection circuit 35, and the second zero-crossing detection circuit 35 is connected to the load 10. The second zero-crossing detecting circuit 35 is configured to detect a zero-crossing point of a current of the load 10 according to a second threshold voltage when the load 10 is in an operating state, and output a second zero-crossing synchronizing signal. The second zero-crossing detection circuit 35 and the first zero-crossing detection circuit 57 may use the same voltage threshold as a threshold, and the first threshold voltage and the second threshold voltage may be set by a zero-crossing detection experiment. The second control circuit 33 is also connected to a second zero-crossing detection circuit 35. The second control circuit 33 is configured to receive the second zero-crossing synchronization signal when the load 10 is in the operating state, so as to output the second switching signal to the second switch 31.
For example, referring to fig. 5, the first switch 55 is turned on during a first period of the ac cycle according to the first switching signal; the second switch 31 is opened during a first period of the alternating current cycle in dependence on the second switching signal. Also for example, the first switch 55 is turned off during a second period of the ac cycle in response to the first switching signal; the second switch 31 is switched on during a second period of the alternating current cycle in dependence on the second switching signal. The zero-crossing time point of the alternating current cycle is located in a first time period, and the first time period and the second time period are time periods in the same alternating current cycle. Thus, the switch adapter 50 and the intelligent switch 30 work in turn strictly according to the zero crossing point as the reference in each alternating current cycle, and the switch adapter 50 and the intelligent switch 30 are matched in time sequence, so that a high-power supply can be provided for the intelligent switch 30 under the condition that the normal switching working state of the load 10 is not influenced.
The intelligent switch 30 may further include a power supply circuit 37, the power supply circuit 37 is connected to the ac loop, the power supply circuit 37 is further connected to the second control circuit 33, and the power supply circuit 37 may be connected in parallel with the second zero-crossing detection circuit 35. In this way, since the current generated by the intelligent switch 30 does not affect the load 10, even if the load 10 with a power as low as 3W is connected, the power of the power supply circuit 37 can be set to be larger, which is helpful for the power supply circuit 37 to drive large energy consumption devices such as a multimedia intelligent interactive terminal with color liquid crystal touch screen, voice recognition, music playing, and other functions.
The intelligent switch 30 may further include a current sampling circuit 39, and the current sampling circuit 39 is connected to the ac loop, the power supply circuit 37, and the second control circuit 33. The current sampling circuit 39 is configured to detect the current of the load 10 and output a current detection signal to the second control circuit 33. The second control circuit 33 is configured to receive the current detection signal and output a third switch signal to the second switch 31. The second switch 31 is turned on for a preset time period according to the third switch signal.
The second control circuit 33 controls the on-time of the second switch 31 by detecting the output current of the current sampling circuit 39, and the heavier the load 10 of the power supply circuit 37 is, the higher the output voltage of the current sampling circuit 39 is, the longer the second control circuit 33 controls the off-time of the second switch 31, so that the longer the charging time of the power supply circuit 37 is, and vice versa. Therefore, the power supply time distribution between the intelligent switch 30 and the load 10 can be dynamically adjusted, the energy consumption of the intelligent switch 30 is reduced, and the adaptability of the load 10 is improved.
The embodiment of the present application further provides an intelligent home system, and the intelligent home system includes the intelligent switch system 100 of any one of the above embodiments.
In the smart home system provided by the embodiment of the application, the load 10 is disposed in an ac loop, and the smart switch 30 is connected in series with the load 10, and is configured to control a working state of the load 10. The switch adapter 50 is connected in parallel with the load 10, and is configured to detect an operating state of the load 10, and is turned on when the load 10 is in a non-operating state, so that the load 10 can be short-circuited, and thus even when a rated power of the load 10 is low, a current generated by the smart switch 30 does not affect the load 10, and it is helpful for avoiding abnormalities such as micro-lighting and flickering of the load 10 such as a lamp. In addition, when the load 10 is in the working state, the working state of the switch adapter 50 is opposite to the working state of the intelligent switch 30, which is helpful for adjusting the power supply time distribution between the intelligent switch 30 and the load 10, reducing the energy consumption of the intelligent switch 30, and improving the adaptability of the load 10.
