Description

Circuit control system, serial control device and control method thereof

Technical Field

The invention relates to the field of circuit control, in particular to a circuit control system, a series control device and a control method thereof, which are particularly suitable for controlling lamps.

Background

In the field of existing circuit control, such as lamp control, passive and wireless control modes are more and more widely applied.

Taking lamp control as an example, an existing passive wireless control device generally includes a remote controller and a lamp control switch, and in the working process, the remote controller sends a signal to the lamp controller to control the operation of the lamp. Both the remote control and the luminaire controller require separate power to maintain operation.

The remote controller mainly has two power supply modes, one mode is a battery power supply mode, and the other mode is a self-generating power supply mode. The lamp controller has two power supply modes, one mode is directly connected in parallel between a zero line and a live line, for example, and directly obtains electric energy from the circuit, and the other mode is connected in series in the circuit for operating the lamp and obtains electric energy from the circuit for operating the lamp.

Due to the respective electric energy obtaining mode and the working characteristic of the remote controller and the lamp controller, certain matching relations are formed between the remote controller and the lamp controller. For example, the remote controller powered by a battery can continuously provide more electric energy when sending signals, and the remote controller in a self-generating mode can collect the energy generated by pressing to convert the energy into the electric energy, but the electric energy obtained at one time is less, so that the signal sending time is short.

Correspondingly, the parallel lamp controller continuously obtains electric energy from the circuit, does not influence the work of the lamp, can receive pulse signals with short existence time, and can be matched with the remote controller in a self-generating mode. However, the lamp controller in the parallel connection mode is continuously in a working state with high power, and consumes more electric energy, and more importantly, the zero line and the live wire are required to be supplied with power simultaneously, so that when only a single live wire is arranged in a lamp circuit in a building, the zero line needs to be re-wired and installed, the engineering quantity is large, and the lamp controller is relatively complex.

The lamp controllers in series connection are connected in series in a working loop of the lamp, working electric energy needs to be obtained from the loop, if the lamp controllers are continuously in a standby state, the working loop of the lamp needs to continuously provide working current of the lamp controllers, and the working power of the existing lamp controllers is high, so that the lamp can continuously pass through the large working current, the lamp can emit slight light or flicker, the use experience of the lamp of a user is influenced, and the service life of the lamp is simultaneously reduced. In order to avoid such a situation, the conventional series-connected luminaire controller usually sets the sleep mode, that is, sets the operating time and the sleep time to be at different powers, for example, sets the ratio of the operating time to the sleep time to be 1:100, so that the power consumption of the luminaire controller in the sleep state is low, the current is low, and therefore the luminaire does not appear to light or flicker during sleep. However, there is a problem that a long time is required for waking up the lamp controller in the sleep mode, that is, the length of the control signal can at least maintain the whole working and sleep time, so that the lamp controller can be woken up relatively accurately and stably receive the control signal, that is, the remote controller needs to transmit a long code at one time, otherwise, the lamp controller cannot be woken up, that is, the remote controller cannot control the lamp controller. Therefore, for the serial or dormant lamp controller, the remote controller powered by the battery must work cooperatively, that is, the remote controller in the self-generating mode cannot work cooperatively with the lamp controller.

In addition, the lamp controller in the series sleep mode needs to distinguish between the working state and the sleep state, the corresponding circuit is more complicated, and there is a risk that no control signal is received.

Referring to fig. 1 to 7, there is shown a circuit control system and a series control apparatus 20 according to a first embodiment of the present invention. FIG. 1 is a block diagram schematic of a circuit control system according to a first embodiment of the present invention. Fig. 2 is a block diagram schematically illustrating a series control apparatus according to a first embodiment of the present invention.

The circuit control system is used for connecting a load circuit and controlling the operation of at least one load 100, and comprises a mobile control device 10 and a serial control device 20, wherein the mobile control device 10 can movably send a control signal to the serial control device 20, and the serial control device 20 controls the operation of the load 100.

The load 100 is exemplified but not limited to a lamp, an electrical appliance, and the manner of controlling the operation of the load 100 is exemplified but not limited to controlling the on/off of the operation current supplied to the load 100. Of course, in other embodiments of the present invention, the circuit control system may also be controlled in other manners, such as controlling the specific operating state of the load 100. In some embodiments, the circuit control system is adapted for control of a luminaire, such as controlling the on/off of a luminaire, or for controlling the combined operation of a plurality of luminaires.

The series control device 20 is configured to be serially connected to a circuit in which the load 100 operates, so as to directly obtain electric energy from a circuit in which the load 100 operates to operate, and directly control the operation of the load 100.

The series control device 20 has two interfaces 201 for connecting to the circuits in which the load 100 operates, such as an input interface and an output interface. For example, when the working circuit of the load 100 is a two-phase circuit composed of the neutral line and the live line, the series control device 20 is connected in series to the neutral line side. That is, the load 100 is connected across the neutral line and the live line, and the series control device 20 is connected in series between the neutral line and the load 100. It should be noted that, in the conventional parallel connection mode, the control device at one end of the lamp needs to be provided with a plurality of connectors, for example, 4 connectors are needed, two connectors are used for connecting the power supply circuit to obtain electric energy, and two interfaces 201 are used for connecting the load 100, so that the circuit is relatively complex, whereas in the present invention, at least 2 interfaces 201 are needed, that is, the circuit can be conveniently accessed, and the circuit is simpler. Of course, in other embodiments of the invention, more interfaces 201 may be provided, and the invention is not limited in this respect.

It should be noted that the conventional wired switch is usually connected in series in the working loop of the load 100, and when the line is arranged, the line is usually reserved in the wall, that is, a zero line connecting the wired switch and a connector of the load 100 need to be provided, whereas the series control device 20 of the present invention needs to be connected in series in the working loop of the load 100, so that the series control device 20 can simply connect the series control device 20 into the working loop by using the original interface 201 of the wired switch without separate wiring, thereby quickly converting the wired control mode into the wireless control mode. In other words, the connection mode of the series control device 20 is the same as that of the conventional wired switch, so that the conventional wired switch can be directly replaced, and the control mode can be changed without changing the original circuit.

Further, in some embodiments of the present invention, the mobile control device 10 is a self-generating wireless signal transmitting device, which collects energy for operating the mobile control device 10 and converts the energy into electric energy, so as to send a control signal to the series control device 20 via the electric energy. That is, in the operation of the circuit control system, the mobile control device 10 is operated to generate electric power to send a control signal to the series control device 20, thereby controlling the operation of the load 100 through the series control device 20. In other words, the user can control the operation of the load 100 through the variable position of the mobile control device 10 within a predetermined range, i.e., realize free wireless control, and the mobile control device 10 is a self-generating device, so that it is not necessary to install a battery, the trouble of replacing the battery is avoided, and power is saved.

More specifically, in some embodiments of the present invention, the mobile control device 10 includes at least one button 11 and a generator 12, and when the button 11 is pressed, the generator 12 is driven to generate electric energy, i.e. the pressed energy is converted into electric energy for sending a control signal. The mobile control device 10 may be an electromagnetic self-generating wireless signal transmitter. That is, the movement control device 10 can generate power by electromagnetic induction to transmit a control signal. It will be appreciated by those skilled in the art that the manner in which the motion control apparatus 10 generates electricity is not a way of the present invention. Preferably, the mobile power generation device of the present invention is a wireless signal transmitting device that performs self-power generation by an electromagnetic induction principle. In some embodiments of the present invention, when the time of the control signal transmitted by the mobile control device does not exceed 50ms, the serial control device 20 makes an immediate response to control the operation of the load 100, without affecting the operating state of the load 100, such as without causing a lamp to flicker. The mobile control device 10 includes a communication unit 13 for performing communication control with the series control device 20. Further, the generator 12 is electrically connected to the communication unit 13 to provide working power for the communication unit 13. In operation, the key 11 is pressed to drive the generator 12 to generate electric energy, and the electric energy is transmitted to the communication unit 13, so that the communication unit 13 can work to send a control signal.

The series control device 20 includes a power-taking control unit 21, a control switch 22, a switching power supply unit 24, a switch driving unit 25, and a sleep-free communication unit 23.

The power-taking control unit 21 selectively controls a path through which current passes so as to controllably supply electric power. More specifically, the power-taking control unit 21 selectively controls power supply to the control switch 22, the non-sleep communication unit 23, or the switching power supply unit 24. The power-taking control unit 21 is electrically connected with the control switch 22, the non-sleep communication unit 23 and the switching power supply unit 24. More specifically, the non-sleep communication unit 23 and the communication unit 13 of the mobile control apparatus 10 are configured to be communicatively connected.

In some embodiments of the present invention, the power-taking control unit 21 selects the path through which the control current passes periodically, for example, selects and controls the passing paths of two half periods in one period to be different.

The control switch 22 is used for controlling the on-off of the circuit between the power-taking control unit 21 and the load 100. When the series control device 20 is connected to the circuit of the load 100, the control switch 22 is disposed between the power-taking control unit 21 and the load 100. When the load 100 needs to work, the control switch 22 is closed, so that the current passing through the power-taking control unit 21 is transmitted to the load 100 through the control switch 22, so that the load 100 works. When the load 100 does not need to work, the control switch 22 is turned off, that is, the current passing through the power-taking control unit 21 cannot reach the load 100 through the control switch 22. In other words, the branch in which the control switch 22 is located provides the load 100 with a current in an operating state, such as a current up to a rated power operation, when a current reaches the load 100 through the control switch 22, the load 100 can operate normally, and when a current does not reach the load 100 through the control switch 22, the load 100 does not operate or the load 100 is in a state far below the rated power. For example, but not limited to, the normal operation is not affected, that is, the abnormal condition that the use effect is affected, such as occasional, intermittent flicker, slight brightness and the like, caused by the unstable operation state of the control device, of the 3-10W low-power LED lamp is not caused.

The control switch 22 can be an electronically controlled switch module, such as a relay, and it should be understood by those skilled in the art that the particular type of control switch 22 is not a limitation of the present invention. The control switch 22 has an open state and a closed state, when the control switch 22 is in the closed state, the normal working circuit of the load 100 is turned on, i.e., the load 100 works normally, and when the control switch 22 is in the open state, the normal working circuit of the load 100 is turned off, i.e., the load 100 does not work. Preferably, in some embodiments of the present invention, the initial state of the control switch 22 is an open state.

Referring to fig. 3, 5A, and 5B, the switching power supply unit 24 is used to adjust the electric energy passing through the switching power supply unit 24 by the power-taking control unit 21, such as performing voltage and current adjustment. More specifically, the switching power supply unit 24 adjusts the electric energy from the power-taking control unit 21 to the load 100 and the non-sleep communication unit 23, so that the currents flowing through the switching power supply unit 24 to the load 100 and the non-sleep communication unit 23 are both small, thereby preventing the load 100 from starting to work, such as the phenomenon of flickering or lighting of the lamp, and allowing the non-sleep communication unit 23 to continuously work at a low power when the currents only flow through the switching power supply unit 24 to the load 100. The switching power supply unit 24 is disposed on both sides of the control switch 22, and when the control switch 22 is closed, the switching power supply unit 24 is de-energized to stop operating, and when the control switch 22 is opened, the switching power supply unit 24 operates. When the control switch 22 is turned on or turned off at the instant, the switching power supply unit 24 obtains the electric energy when the control switch 22 is turned off or turned off at the instant, so as to supply the non-sleep communication unit to work 23. When the control switch 22 is closed, the switching power supply unit 24 is short-circuited, and current does not pass through the switching power supply unit 24, so that the switching power supply unit 24 does not operate.

When the series control device 20 is connected to the circuit of the load 100, the control switch 22 electrically connects the power-taking control unit 21 and the load 100 with the non-sleep communication unit 23. More specifically, the switching power supply unit 24 is disposed at both sides of the control switch 22, that is, the current passing through the power-taking control unit 21 can selectively reach the load 100 through the control switch 22 and/or the switching power supply unit 24, thereby forming different closed working loops.

When the control switch 22 is turned on or turned off at the instant, the switching power supply unit 24 obtains the electric energy when the control switch 22 is turned off or turned off at the instant, so that the non-sleep communication unit works 23, and the electric energy obtained at the instant by the switching power supply unit 24 maintains the work of the non-sleep communication unit 23 before the power-taking control unit 21 starts to supply power; when the control switch 22 is turned on, the switching power supply unit 24 loses power and stops working, the current passing through the power-taking control unit 21 is transmitted to the load 100 through the control switch 22, so that the load 100 can work normally, and the non-sleep communication unit 23 directly obtains electric energy from the power-taking control unit 21 and maintains working, that is, the power-taking control unit 21 provides a current for the non-sleep communication unit 23 to work at low power, that is, the non-sleep communication unit 23 continuously works at low power and continuously receives the control information sent by the mobile control device 10. When the control switch 22 is turned off, the current passing through the power-taking control unit 21 is adjusted to the non-sleep communication unit 23 by the current of the switching power supply unit 24, and a part of the smaller current is transmitted to the load 100 to form a closed circuit, for example, a low-power closed circuit is formed between the zero line and the live line, and at this time, the current in the circuit is mainly used for maintaining the operation of the non-sleep communication unit 23, so that the current passing through the load 100 is smaller, and the load 100 cannot operate, for example, a lamp is flickering and shining. Therefore, the non-sleep communication unit 23 can obtain the operating power to continuously receive the signal transmitted by the motion control device 10 regardless of whether the load 100 is in the operating state or the load 100 is in the non-operating state, so that it is not necessary for the motion control device 10 to transmit a long signal, and the series control device 20 can accurately receive the signal transmitted by the motion control device 10, and thus the phenomenon of control inflexibility does not occur.

The switching power supply unit 24 is, for example and without limitation, a switching power supply module, and of course, the switching power supply unit 24 may also enable other power supply adjusting devices, for example, the switching power supply unit 24 is a step-down AC-DC converter, and for example, the voltage output by the switching power supply unit is in a range of 1.5-24V.

The switch driving unit 25 is used for driving the control switch 22 to work, such as driving the control switch 22 to be turned on or off. Further, the switch driving unit 25 obtains a signal from the sleep-less communication unit 23 to drive the control switch 22 to operate. That is, the sleep-less communication unit 23 sends a control signal to the switch driving unit 25, and drives the control switch 22 to operate via the switch driving unit 25, so as to control the on/off of the operating current of the load 100, for example, control the on/off of the operating current from the power-taking control unit 21 to the load 100 through the control switch 22, thereby implementing wireless control on the load 100.

Further, the switch driving unit 25 obtains the passing power from the switch power supply unit 24, that is, the switch power supply unit 24 provides the switch driving unit 25 with the working power in a manner of electrically connecting the switch driving unit 25. In other words, the switch driving unit 25 electrically connects the non-sleep communication unit 23, the switching power supply unit 24, and the control switch 22, respectively. The switch driving unit 25 is exemplified but not limited to a relay driving module.

Further, referring to fig. 2 and 3, the power-taking control unit 21 includes a first half-cycle control element 211, a second half-cycle control element 212, and a pulse width controller 213, wherein the first half-cycle control element 211 and the second half-cycle control element 212 selectively control the current of the two opposite half-cycles, respectively. Preferably, the first half-cycle control element 211 and the second half-cycle control element 212 selectively control currents in opposite directions. For example, during a sinusoidal current cycle, the first half-cycle control element 211 selects to control the current for the positive half-cycle and the second half-cycle control element 212 selects to control the current for the negative half-cycle. That is, half-cycles of current are selectively passed through the first half-cycle control element 211 and half-cycles of current are selectively passed through the second half-cycle control element 212. The pulse width controller 213 controls the second half-cycle control element 212 to be turned off in a predetermined interval, and obtains the electric energy in the circuit to supply power to the non-sleep communication unit 23. In some embodiments, the pulse width controller 213 controls the second half-cycle control element 212 to turn off for a smaller interval at a zero-crossing of the circuit.

Further, when the series control device 20 is switched into the circuit of the load 100, the current passing through the selected half cycle of the power-taking control unit 21 passes through the first half cycle control element 211, when the control switch 22 is closed, the half cycle current passes through the first half cycle control element 211 to reach the control switch 22, and is transmitted to the load 100 through the control switch 22 to normally operate, when the current enters the second half cycle, the pulse width controller 213 controls the second half cycle control element 212 to disconnect a smaller voltage interval at a zero crossing point so as not to affect the normal operation of the load 100, and at the moment of disconnection, the pulse width controller 213 obtains the electric energy in the circuit to supply the non-sleep communication unit 23 to operate. In particular, the pulse width controller 213 draws power to support operation of the non-sleep communication unit 23 for a plurality of cycles. When the control switch 22 is turned off, the half-cycle current reaches the switching power supply unit 24 through the first half-cycle control element 211, is regulated by the switching power supply unit 24 and is transmitted to the non-sleep communication unit 23 and the load 100 respectively, when the current enters the second half-cycle, the pulse width controller 213 controls the second half-cycle control element 212 to turn off a smaller voltage interval at the zero-crossing point, and at the moment of turning off, the pulse width controller 213 acquires the electric energy in the circuit for the non-sleep communication unit 23 to work.

That is, when the control switch 22 is turned off, the non-sleep communication unit 23 draws power for low power operation from the switching power supply unit 24 when the load 100 is not operated, and when the control switch 22 is turned on, the load 100 is operated, the switching power supply unit 24 is not operated, and the non-sleep communication unit 23 draws power from the pulse width controller 213, so that the non-sleep communication unit 23 can continuously draw power for low power operation regardless of whether the load 100 is operated and regardless of which half cycle the current in the circuit is in, i.e., the non-sleep communication unit 23 is continuously in a low power operation state without sleep.

Referring to fig. 6, a schematic diagram of a power-taking control principle of the series control apparatus according to the first embodiment of the present invention is shown. Taking one voltage cycle as an example, one voltage cycle is divided into two control intervals, namely a first control interval 2110 and a first second control interval 2120, the first control interval 2110 corresponds to an interval through which the first half-cycle control element 211 selectively passes, the second control interval 2120 corresponds to an interval through which the second half-cycle control element 212 selectively passes, in a period controlled by the second half-cycle control element 212, the second half-cycle control element 211 is controlled to be disconnected at a predetermined interval from a zero-crossing point 2120 of the first control interval 2110 and the second control interval 2120 to form a disconnection interval 2120, and in the remaining interval of the second control interval 2110, the disconnection interval 2120 is selected to pass, so that the pulse width empty controller 23 is powered at the disconnection interval 2120. That is, the current at the first control interval 2110 of one cycle is transmitted to the switching power supply unit 24 or the load 100 through the first half-cycle control element 211, the current at the second control interval 2120 is transmitted to the switching power supply unit 24 or the load 100 through the second half-cycle control element 212, and the disconnection interval 2120 near the zero-crossing point 2120 of the second control interval 2120 disconnects the current in the second half-cycle control element 212, so that the pulse width controller 213 acquires the power on both sides of the second half-cycle control element 212 at the disconnection interval 2120 for the non-sleep communication unit 23 to operate, thereby operating in the repeated cycles. In some embodiments, the pulse width controller 213 stores power for a plurality of periods of operation of the non-sleep communication unit 23, i.e., after a period, the pulse width controller 213 continues to power the non-sleep communication unit 23 even though no power is provided.

The non-sleep communication unit 23 includes a communication module 231, a voltage stabilizing module 232, and a microprocessor control module 233, where the communication module 231 is used for being communicatively connected to the mobile control device 10, the voltage stabilizing module 232 is used for adjusting the power transmitted to the communication module 231, and the microprocessor control module 233 is used for processing the control signal and sending the control information to the switch driving unit 25.

Further, the pulse width controller 213 is electrically connected to the voltage stabilizing module 232, so as to regulate the power transmitted by the pulse width controller 213 through the voltage stabilizing module 232. The switching power supply unit 24 is electrically connected to the voltage stabilizing module 232 so as to regulate the electric energy transmitted by the switching power supply unit 24 through the voltage stabilizing module 232. That is, the power transmitted to the non-sleep communication unit 23 through the pulse width controller 213 and the switching power supply unit 24 can be regulated by the voltage stabilizing module 232, so as to ensure the low-power stable operation of the non-sleep communication unit 23.

In some embodiments of the present invention, the first half cycle control element 211 can be implemented as a diode to select the current through the positive half cycle and the second half cycle control element 212 can be implemented as a MOS transistor to select the current through the negative half cycle. The pulse width controller 213 selects a zero crossing point to a predetermined voltage range in a circuit cycle to control the second half-cycle control element 212 to be turned off, and obtains electric energy by the instant voltage difference between two ends of the second half-cycle control element 212 to supply the non-sleep communication unit to work. By way of example and not limitation, the pulse width electricity taking module obtains electric energy of a negative half shaft of 0-18V. When the control switch 22 is in a closed state, when the alternating current is in a positive half cycle, the diode supplies power to the load 100, such as a lamp, and then the positive half cycle is ended, the alternating current starts to change to a negative half cycle, and the state of the MOS transistor is off from a zero-crossing point position to a predetermined voltage interval, such as an interval of 0-18V, and during the off time of the MOS transistor, the pulse width power-taking module obtains an instantaneous power supply, and the obtained instantaneous power can support the series control device 20 to maintain for a plurality of cycles; when the voltage of the ac power rises above a predetermined level (e.g., 18V), the MOS transistor becomes conductive, and the negative half cycle power supply supplies power to the load 100, such as a lamp, because the MOS transistor is turned off for a very short time, and thus the brightness of the lamp cannot be visually observed to change, thereby realizing that the series control device 20 operates continuously at low power while the load 100 operates.

It should be noted that, in this embodiment of the present invention, the voltage control range of the pulse width controller 213 is exemplified as 0-18V, it should be understood by those skilled in the art that the specific control off voltage range of the pulse width controller 213 is not a limitation of the present invention, and in other embodiments of the present invention, the voltage control range of the pulse width controller 213 may also be other ranges, such as 0-15V, 0-16V, 0-17V, 0-18V, 0-19V, 0-20V, 0-21V. Preferably, the pulse width controller 213 takes power in a range of 0-18V, and the series control device can continuously operate in this range, and at the same time, the circuit in the circuit is small enough to prevent the lamp from flickering.

Further, in some embodiments of the present invention, referring to fig. 7, the pulse width controller 213 is implemented as an operational amplifier, by which the second half-cycle control element 212 is controlled to be turned off for a predetermined interval. A, B at both ends of the second half-cycle control element 212, the operational amplifier monitors the voltage at both ends A, B of the second half-cycle control element 212, and once the amplitude of the negative half-cycle ac voltage exceeds 18V (exemplary value), the operational amplifier immediately outputs a signal to turn on the MOS transistor, so that the voltage difference between two points A, B is zero, and in the next half-cycle, the above process is repeated, so that when the lamp is turned on, the operational amplifier controls the on-off time of the MOS transistor to obtain the power required by the system at two points A, B, and the series control device 20 can also have power maintaining operation, i.e. continuously receive the control signal of the mobile control device 10.

Further, the non-sleep communication unit 23 and the switching power supply unit 24 select module types that are matched with each other, so that the control circuit operates with low power consumption as a whole. For example, in some embodiments, taking a 3W LED lamp as an example, the switching power supply unit 24 employs a high-efficiency device, for example, the switching power supply unit 24 may employ a step-down AC-DC converter, the output voltage of the switching power supply unit 24 may range from 1.5V to 24V, for example, the switching power supply unit 24 may be formed by chips such as LNK3203D of PI corporation, UCC28730 of TI corporation, and the like, and provide 3.3V DC power required by the communication module 231 and 12V DC power required by the control switch 22; the communication module 231 of the non-dormancy communication unit 23 is also selected from devices with ultra-low power consumption, the communication module 231 of the non-dormancy communication unit 23 can adopt a7129 of an amicocom company to realize the function of receiving and transmitting digital high-frequency signals, when the power supply voltage VCC of the A7129 is actually measured to be reduced to 2V, the normal working current is 3.9mA, the microprocessing control module 233 adopts low-power-consumption devices and performs intermittent working processing to reduce the power consumption of the microprocessing control module 233, and the standby current of the singlechip in a dormancy state can be as low as about 10 uA. Therefore, the total current consumption of the communication module 231 plus the microprocessor control module 233 is within 4mA, and if the power supply voltage is maintained at 2V, the power consumption is 4 × 2 — 8 mw; the voltage stabilizing module 232 employs a high-efficiency DC-DC chip, and when the voltage supplied to the non-sleep communication unit 23 by the switching power supply unit 24 and/or the pulse width controller 213 fluctuates, the DC-DC chip of the voltage stabilizing module 232 can provide a stable operating voltage to the communication module 231, so that the non-sleep communication unit 23 is continuously in a low-power operating state for receiving the control signal through combination of different schemes. It should be noted that although the non-sleep communication unit 23 performs intermittent operation processing on the microprocessor control module 233 to reduce the power consumption of the entire communication module 231, the communication module 231 does not sleep, i.e., continuously receives a control signal, and therefore does not miss the control signal transmitted by the mobile control device 10 even when the power is low. The conversion efficiency of DC-DC is 90%, so that the total power consumption of DC-DC when supplying power to the communication module 231 is 8/0.9-8.89 mw, and assuming that the conversion efficiency of AC-DC of the switching power supply unit 24, i.e. 220V AC to 3.3V is 80%, the consumption current of the series control device 20 of the entire series is 8.89/0.8-11 mw in the standby state, i.e. the state where the lamp is not lit. Therefore, when the circuit control system provided by the invention is used, when the power of the lamps connected in series is as low as 3W, the lamps can not flicker, and the design purpose of the circuit control system can be realized. Of course, in other embodiments of the present invention, the load 100, such as a lamp, may have other power, and it should be understood by those skilled in the art that the power of the load 100 is not limited by the present invention.

In some embodiments of the present invention, the voltage stabilizing module 232 is a BUCK type DC-DC converter, and the conversion efficiency of the DC-DC of the voltage stabilizing module 232 is greater than a predetermined value, such as greater than 80%, for low power operation of the non-sleep communication unit 23. In some embodiments of the present invention, the DC-DC conversion efficiency of the voltage stabilization module 232 is greater than a predetermined value, such as greater than 70%, for low power operation of the non-sleep communication unit 23. In some embodiments of the present invention, the voltage stabilization module 232 is selected from the group consisting of: one of a BUCK type DC-DC converter, a BOOST DC-DC converter, and an LDO regulator.

Further, in some embodiments of the present invention, the mobile control device 10 transmits the radio frequency signal according to a predetermined flow. For example, the operation process of the mobile control device 10 may be:

when the key 11 of the mobile control device 10 is pressed, the generator 12 is prompted to generate electricity to generate transient inductive pulse energy; after the electric pulse energy is stored in a capacitor, the pulse is shaped and delayed by an energy oscillator, for example, the existing time of the electric pulse is prolonged from 1ms to more than 6ms, so as to maintain enough working electric energy to supply the transmitting circuit to send out the coded signal.

Fig. 4 is a schematic operation flow diagram of a mobile control device according to a first embodiment of the present invention. After the mobile control device 10 starts to work after generating power, initializing, including initializing a single chip (working module type setting, peripheral configuration) and a radio frequency chip (radio frequency chip parameter configuration and frequency calibration) of the mobile control device 10; further, the information of the key 11 is detected through an input port of a single chip of the mobile control device 10 (for example, the rocker type mobile control device 10 is a high level signal, and the rebound type mobile control device 10 is a low level signal), and the key 11 signal and the device information form an ID for packaging, and in order to prevent the instability of the transmitted signal when the energy is exhausted, a check code is added to the tail of each packet of signals. Further, the frame format of the transmitted rf control signal of the mobile control device 10 may be: 4 bytes of synchronous signals, 4 bytes of equipment ID, 1 byte of key signals and 2 bytes of check; after the radio frequency control signal is sent, the single chip microcomputer and the radio frequency IC both enter a dormant state, wait for 3ms, finish the dormant state, and then start the next information sending; before the next transmission, whether the key information needs to be redetected is judged. The springback self-generating mobile control device 10 needs to detect the key information again each time the information is transmitted until the electric energy is exhausted and stops working; the seesaw-type self-generating mobile control device 10 detects key information again every time three packets of data are sent, and stops sending information if no key information exists. It should be noted that the operation of the mobile control device 10 sending the radio frequency signal is only used to illustrate one of the control signal sending processes, and is not a limitation of the present invention, that is, in other embodiments of the present invention, the mobile control device 10 may send the control signal through other processes or other coding manners.

Referring to fig. 14, in some embodiments of the present invention, the mobile control apparatus 10 includes a plurality of the keys 11 to control a plurality of loads 100 to operate, in which case, in the radio frequency signal transmitted by the mobile control apparatus 10, the plurality of keys 11 may be distinguished by encoding, for example, the keys 11 are coded by bits to implement a combined key function, or different keys 11 are implemented to control different loads 100.

Further, in some embodiments of the present invention, when the mobile control device 10 and the serial control device 20 work together, a pairing process is required. That is, the movement control device 10 and the series control device 20 are made to correspond by the pairing process. Preferably, the pairing process is suitable for a situation where a plurality of mobile devices or a plurality of keys 11 control a plurality of loads 100, such as for example, each key 11 correspondingly controls a different load 100.

Further, the serial control device 20 may include a pairing button, and the pairing button is communicatively connected to the non-sleep communication unit 23, so as to trigger the non-sleep communication unit 23 to enter a pairing process after the pairing button is actuated. That is, the serial control device 20 has a pairing operation mode, and when the pairing button is actuated, the serial control device 20 enters the pairing operation mode to wait for pairing with the mobile control device 10.

For example, the pairing process of the series control device 20 may be: when the serial control device 20 is in the standby state, the pairing button is pressed for several seconds, an indicator light of the pairing button flickers, and a waiting pairing mode is entered; the mobile control device 10 sends a pairing control signal to the serial control device 20, the pairing signal is captured by the communication module 231 of the serial control device 20 waiting for pairing, the communication module 231 sends the received pairing signal to the microprocessor control module 233 for storage, after the storage is finished, the indicator light of the serial control device 20 is turned off, and the pairing process is finished. If other mobile control devices 10 or other keys 11 are needed to be added to the serial control device 20, the above steps are repeated. When the mobile control device 10 includes a plurality of keys 11 to control a plurality of loads 100, the keys 11 may be paired to implement a pairing process of the plurality of keys 11, and after the pairing is completed, the serial control device 20 controls the operation of the control switch 22 according to the control information of the keys 11.

For example, the working process of the circuit control system may be: the mobile control device 10 is operated to generate electric energy and send a control signal to the serial control device 20, when the serial control device 20 receives the control signal and if the button 11 is determined to be paired by the microprocessor control module 233 of the non-sleep communication unit 23, the output port of the microprocessor control module 233 outputs a high level to the switch driving unit 25; the switch driving unit 25 drives the control switch 22 to be closed, the load 100 is turned on to work, for example, the lamp works by emitting light, at this time, the potential difference between the two ends of the control switch 22 is zero, and the switching power supply unit 24 is powered off to stop working; the pulse width controller 213 cooperates with the power-taking control unit 21 to obtain electric energy to provide low-power electric energy for the non-sleep communication unit 23, so as to continuously receive the control signal sent by the mobile control device 10. When the non-sleep communication unit 23 receives the control signal again, the output port output by the micro-processing control module 233 outputs a high level to the switch driving unit 25, the switch driving unit 25 drives the control switch 22 to be turned off, the load 100 does not work, and at this time, the switch power supply unit 24 works to provide low-power working electric energy for the non-sleep communication unit 23.

It is also worth mentioning that the mobile control device 10 of the present invention is directly communicatively connected to the tandem control device 20 without a gateway as a signal relay. That is to say, the tandem control device 20 is in a non-sleep state and continuously receives the control signal sent by the mobile control device 10, so that a gateway in the prior art is not needed as an intermediate medium, and the control signal sent by the mobile control device 10 is transferred and stored, so that the control system is simpler and the control is more convenient and direct.

Fig. 8 is a block diagram schematically illustrating a series control apparatus 20 according to a second embodiment of the present invention. Fig. 9 is a schematic circuit diagram of a series control apparatus according to a second embodiment of the present invention.

In this embodiment of the invention, the series control means 20 comprises a local switch 26, the local switch 26 being used for local control operations. That is, in the circuit control system, the operation of the load 100 may be independently controlled by one end of the mobile control device 10, or the operation of the load 100 may be independently controlled by one end of the serial control device 20, that is, a combination of wireless and wired dual control is realized.

Further, the local switch 26 is electrically connected to the microprocessor control module 233, so as to send a local control signal to the microprocessor control module 233. That is, when the user triggers the control switch 22 through one end of the serial control device 20, the control switch 22 sends a signal to the microprocessor control module 233, and the microprocessor control module 233 processes the local control signal and sends a signal to the switch driving unit 25, so as to control the on/off of the control switch 22.

The microprocessor control module 233 processes the wireless control signal of the mobile control device 10 and the local control signal of the local switch 26, and sends the signals to the switch driving unit 25, so that one end of the mobile control device 10 or one end of the serial control device 20 independently controls the operation of the load 100.

For example, when the mobile control device 10 sends the wireless control signal to the serial control device 20, the communication module 231 receives the wireless control signal and transmits the signal to the micro-processing control module 233, and the micro-processing control module 233 processes the control signal and controls the control switch 22 to be converted from the current state to another state in combination with the current state of the control switch 22, that is, the state change of the control switch 22 is independently controlled by one end of the mobile control device 10, that is, the state change of the load 100 is independently controlled by the mobile control device 10. When a user operates the local switch 26 at one end of the series control device 20, the local switch 26 sends the local control signal to the microprocessor control module 233, and the microprocessor control module 233 processes the local control signal of the local switch 26 and controls the control switch 22 to be converted from the current state to another state in combination with the current state of the control switch 22, that is, the state change of the control switch 22 is independently controlled by one end of the series control device 20, that is, the state change of the load 100 is independently controlled by one end of the series control device 20.

Further, the local switch 26 may be plural, that is, correspond to plural mobile control devices 10 or plural keys 11 of one mobile control device 10, respectively, that is, an independent dual control function is realized by combining plural local switches 26 and plural mobile control devices 10 or plural keys 11.

In the way that the mobile control device 10 and the serial control device 20 of the plurality of keys 11 cooperate, the plurality of keys 11 of the mobile control device 10 may be respectively paired with the plurality of local switches 26 at one end of the serial control device 20, that is, each group implements local and wireless dual control.

Fig. 10 is a block diagram schematically illustrating a series control apparatus 20 according to a third embodiment of the present invention.

In this embodiment of the present invention, the series control apparatus 20 includes a detection control unit 27, and the detection control unit 27 obtains a zero-crossing signal of the circuit from the power-taking control unit 21, and controls the closing of the control switch 22 to reduce the impact of the transient large current on the control switch 22. For example, the detection control unit 27 may obtain a zero-crossing signal of the circuit from the pulse width controller 213, so as to control the control switch 22 to close at a predetermined time of the zero-crossing signal, i.e. to avoid a transient large current caused by the control switch 22 closing near a current peak position in the circuit.

Further, in some embodiments of the present invention, the detection control unit 27 is electrically connected to the switch driving unit 25, so as to transmit a signal to the switch driving unit 25, and further, the switch driving unit 25 controls the action of the control switch 22 in combination with the information of the detection control unit 27. That is, the switch driving unit 25 controls the operation of the control switch 22 in conjunction with the signals of the microprocessor control module 233 and the detection control unit 27. Of course, in other embodiments of the present invention, the detection control unit 27 may be electrically connected in other manners.

The power-taking control unit 21 selectively controls a path through which current passes so as to controllably supply electric power. More specifically, the power-taking control unit 21 selectively controls the control switch 22 and/or the non-sleep communication unit 23. The power-taking control unit 21 is electrically connected with the control switch 22 and the non-sleep communication unit 23.

In some embodiments, the non-dormant communication unit 23 and the communication unit 13 of the mobile control device 10 are configured as a communication connection.

The control switch 22 is used for controlling the on-off of the circuit between the power-taking control unit 21 and the load 100. That is, when the series control device 20 is switched into the circuit of the load 100, the control switch 22 is disposed between the power-taking control unit 21 and the load 100. When the load 100 needs to work, the control switch 22 is closed, so that the current passing through the power-taking control unit 21 is transmitted to the load 100 through the control switch 22, so that the load 100 works. When the load 100 does not need to work, the control switch 22 is turned off, that is, the current passing through the power-taking control unit 21 cannot reach the load 100 through the control switch 22. In other words, the branch in which the control switch 22 is located provides the load 100 with a current in an operating state, such as a current up to a rated power operation, when a current reaches the load 100 through the control switch 22, the load 100 can operate normally, and when a current does not reach the load 100 through the control switch 22, the load 100 does not operate or the load 100 is in a state far below the rated power.

The switching power supply unit 24 is electrically connected to the output and output interface 201. In other words, the switching power supply unit and the power-taking control unit and the control switch are provided in parallel with the input and output interfaces.

The switching power supply unit 24 is used for regulating the input electrical energy, such as voltage or current regulation. More specifically, the switching power supply unit 24 adjusts the power supplied to the load 100 and the non-sleep communication unit 23 through the input interface, so that the current flowing through the switching power supply unit 24 to the load 100 and the non-sleep communication unit 23 is small, thereby preventing the load 100 from starting to operate, such as the lamp from flickering or lighting, and allowing the non-sleep communication unit 23 to operate continuously at a low power, when the current flows only through the switching power supply unit 24 to the load 100. The switching power supply unit 24 is disposed on both sides of the power-taking control unit 21 and the control switch 22, and when the control switch 22 is closed, the switching power supply unit 24 is powered off to stop working, and when the control switch 22 is turned off, the switching power supply unit 24 works. In other words, when the control switch 22 is closed, the switching power supply unit 24 is short-circuited, and current does not pass through the switching power supply unit 24, so that the switching power supply unit 24 does not operate. The switching power supply unit 24 obtains the electric energy at the moment when the control switch 22 is closed, so as to supply the non-sleep communication unit 23 to work.

When the series control device 20 is connected to the circuit of the load 100, the control switch 22 electrically connects the power-taking control unit 21 and the load 100 with the non-sleep communication unit 23. More specifically, the switching power supply unit 24 is disposed at both sides of the power-taking control unit 21 and the control switch 22, that is, the input current can selectively reach the load 100 through the control switch 22 or the switching power supply unit 24, thereby forming different closed operation loops, such as a load normal operation loop or a series control device low power operation loop.

When the control switch 22 is turned on, the switching power supply unit 24 loses power and stops working, the current passing through the power-taking control unit 21 is transmitted to the load 100 through the control switch 22, so that the load 100 works normally, the non-sleep communication unit 23 and the switch driving unit 25 directly obtain electric energy from the power-taking control unit 21 and maintain working, that is, the power-taking control unit 21 provides the current for low-power working for the non-sleep communication unit 23 and the switch driving unit 25, that is, the non-sleep communication unit 23 works continuously at low power and continuously receives the control information sent by the mobile control device 10. When the control switch 22 is turned off, the input current is regulated to the non-sleep communication unit 23 through the switching power supply unit 24, and a part of the smaller current is transmitted to the load 100 to form a closed circuit, for example, a low-power closed circuit is formed between the zero line and the live line, and the current in the circuit is mainly used for maintaining the operation of the non-sleep communication unit 23, so that the current passing through the load 100 is smaller, and the load 100 cannot be operated, such as the situation that the lamp flickers and shines. Therefore, the non-sleep communication unit 23 can obtain the operating power to continuously receive the signal transmitted by the motion control device 10 regardless of whether the load 100 is in the operating state or the load 100 is in the non-operating state, so that it is not necessary for the motion control device 10 to transmit a long signal, and the series control device 20 can accurately receive the signal transmitted by the motion control device 10, and thus the phenomenon of control inflexibility does not occur. It should be mentioned that, when the control switch 22 is closed or closed at the instant, the switch power supply unit 24 obtains the electric energy at the instant when the control switch 22 is closed, supplies the non-sleep communication unit 23 and the switch driving unit 25 to work, that is, before the electricity-taking control unit is the non-sleep communication unit 23 and the switch driving unit 25 supplies electricity, the switch power supply unit 24 continues to supply electricity to the non-sleep communication unit 23 and the switch driving unit 25, thereby ensuring that the non-sleep communication unit continuously works without sleep.

Further, when the control switch 22 is turned off, the switch driving unit 25 receives the passing power from the switch power supply unit 24, that is, the switch power supply unit 24 supplies the switch driving unit 25 with the operating power in such a manner as to be electrically connected to the switch driving unit 25. When the control switch 22 is closed, the switch driving unit 25 is powered by the switching power supply unit 24 or the power-taking control unit 21. In other words, the switch driving unit 25 electrically connects the non-sleep communication unit 23, the switching power supply unit 24, and the control switch 22, respectively. The switch driving unit 25 is exemplified but not limited to a relay driving module.

Further, referring to fig. 11 and 12, the power-taking control unit 21 includes a first half-cycle control element 211, a second half-cycle control element 212, and a pulse width controller 213, wherein the first half-cycle control element 211 and the second half-cycle control element 212 selectively control the current of the two opposite half-cycles, respectively. Preferably, the first half-cycle control element 211 and the second half-cycle control element 212 selectively control currents in opposite directions. For example, during a sinusoidal current cycle, the first half-cycle control element 211 selects to control the current for the positive half-cycle and the second half-cycle control element 212 selects to control the current for the negative half-cycle. That is, half-cycles of current are selectively passed through the first half-cycle control element 211 and half-cycles of current are selectively passed through the second half-cycle control element 212. The pulse width controller 213 controls the second half-cycle control element 212 to be turned off in a predetermined interval, and obtains the electric energy in the circuit to supply power to the non-sleep communication unit 23. In some embodiments, the pulse width controller 213 controls the second half-cycle control element 212 to turn off for a smaller interval at a zero-crossing of the circuit.

In some embodiments, the sleep-less communication unit 23 is configured to store the power of the power storage element, for example, to store the power of the off interval obtained by the pulse width controller 213 for a plurality of periods of operation of the sleep-less communication unit 23, that is, after a period, even if no power is provided, the power obtained by the pulse width controller 213 is stored and then continues to power the sleep-less communication unit 23.

The series control device 20 includes a low-voltage switching power supply unit 241, a control switch 22, a switching power supply unit 24, a switch driving unit 25, and a non-sleep communication unit 23.

The low-voltage switching power supply unit 241 and the switching power supply unit 24 respectively supply power to the non-sleep communication unit 23, in other words, the low-voltage switching power supply unit 241 and the switching power supply unit 24 are electrically connected to the non-sleep communication unit 23.

The control switch 22 is used for controlling the on-off of the circuit between the power-taking control unit 21 and the load 100. That is, when the series control device 20 is switched into the circuit of the load 100, the control switch 22 is input between the interface 201 and the load 100. When the load 100 needs to operate, the control switch 22 is closed, so that the input current is transmitted to the load 100 through the control switch 22 for the operation of the load 100. When the load 100 does not need to be operated, the control switch 22 is turned off, i.e. the input current cannot reach the load 100 through the control switch 22. In other words, the branch in which the control switch 22 is located provides the load 100 with a current in an operating state, such as a current up to a rated power operation, when a current reaches the load 100 through the control switch 22, the load 100 can operate normally, and when a current does not reach the load 100 through the control switch 22, the load 100 does not operate or the load 100 is in a state far below the rated power.

In some embodiments of the present invention, the control switch 22 is a semiconductor switch device, such as, but not limited to, a thyristor, a MOS transistor, and other switch type semiconductor devices, and it should be understood by those skilled in the art that the specific type of the control switch 22 is not a limitation of the present invention. The control switch 22 has an open state and a closed state, when the control switch 22 is in the closed state, the normal working circuit of the load 100 is turned on, i.e., the load 100 works normally, and when the control switch 22 is in the open state, the normal working circuit of the load 100 is turned off, i.e., the load 100 does not work. Preferably, in some embodiments of the present invention, the initial state of the control switch 22 is an open state.

The low-voltage switching power supply unit 241 and the switching power supply unit 24 are electrically connected to the input and output interface 201, respectively. In other words, the switching power supply unit 24 and the low-voltage switching power supply unit 241 and the control switch 22 are provided in parallel to the input and output interface 201.

The low-voltage switching power supply unit 241 and the switching power supply unit 24 are used for regulating the input electric energy, such as voltage or current regulation. More specifically, the low-voltage switching power supply unit 241 regulates power from the input interface 201 to the non-sleep communication unit, and the switching power supply unit 24 regulates power from the input interface 201 to the non-sleep communication unit 23 and the load 100.

More specifically, the switching power supply unit 24 adjusts the power supplied to the load 100 and the non-sleep communication unit 23 through the input interface, so that the current flowing through the switching power supply unit 24 to the load 100 and the non-sleep communication unit 23 is small, thereby preventing the load 100 from starting to operate, such as the lamp from flickering or lighting, and allowing the non-sleep communication unit 23 to operate continuously at a low power, when the current flows only through the switching power supply unit 24 to the load 100. The switching power supply unit 24 is disposed on both sides of the control switch 22, and when the control switch 22 is closed, the switching power supply unit 24 is de-energized to stop operating, and when the control switch 22 is opened, the switching power supply unit 24 operates. In other words, when the control switch 22 is closed, the switching power supply unit 24 is short-circuited, and current does not pass through the switching power supply unit 24, so that the switching power supply unit 24 does not operate. The switching power supply unit 24 obtains the electric energy at the moment when the control switch 22 is closed, so as to supply the non-sleep communication unit 23 to work.

The non-sleep communication unit 23 includes a communication module 231, a voltage stabilizing module 232, a microprocessor control module 233 and an energy storage module 234, wherein the communication module 231 is configured to be communicatively connected to the mobile control apparatus 10, the voltage stabilizing module 232 is configured to regulate the electric energy transmitted to the communication module 231, and the microprocessor control module 233 is configured to process a control signal and send control information to the switch driving unit 25.

The energy storage module 234 is configured to store electric energy, and more specifically, the energy storage module 234 stores electric energy input by the low-voltage switching power supply unit 241 and/or the switching power supply unit 24.

The energy storage module 234 is electrically connected to the voltage stabilizing module 232 to supply power to the voltage stabilizing module 232, that is, the electric energy stored in the energy storage module 234 is regulated by the voltage stabilizing module 232 to operate the non-sleep communication unit 23.

In some embodiments of the present invention, the low-voltage switching power supply unit 241 and the switching power supply unit 24 are electrically connected to the voltage stabilizing module 232 so as to regulate the power transmitted by the switching power supply unit 24 through the voltage stabilizing module 232. That is, the power transmitted by the low-voltage switching power supply unit 241 and the switching power supply unit 24 to the non-sleep communication unit 23 can be adjusted by the voltage stabilizing module 232, so as to ensure the low-power stable operation of the non-sleep communication unit 23.

In some embodiments of the present invention, when the control switch 22 is turned off, the switching power supply unit 24 is operated, and power is obtained from both sides of the control switch 22, and forms a closed loop with the load 100 to supply power to the non-sleep communication unit 23. The switching power supply unit 24 is a step-down regulating circuit, such as a BUCK step-down circuit, so that the current reaching the load 100 through the switching power supply unit 24 is relatively small, and the load 100 does not work, such as a lamp does not flicker. In other words, when the control switch 22 is turned off, the circuit current formed by the switching power supply unit 24, the non-sleep communication unit, and the load is small by the action of the switching power supply unit 24, so that the load 100 does not operate, and the non-sleep communication unit 23 operates with low power consumption.

In some embodiments of the present invention, when the control switch 22 is closed or at the closing moment, the switching power supply unit 24 obtains the closed power and stores it in the energy storage module 234 to continue to operate the non-sleep communication unit 23.

When the control switch 22 is turned on or turned off for a predetermined time, the switching power supply unit 24 loses power and stops working, the input current is transmitted to the load 100 through the control switch 22 for the load 100 to work normally, and the non-sleep communication unit 23 and the switch driving unit 25 are powered by the low-voltage switching power supply unit 241 to maintain working. The low-voltage switching power supply unit 241 supplies a current for low-power operation to the non-sleep communication unit 23 and the switch driving unit 25, i.e., causes the non-sleep communication unit 23 to continuously operate at low power, and continuously receives control information transmitted from the mobile control device 10. For example, after the control switch is closed, the power supplied by the storage module 234 is used for operating the non-sleep communication unit, when the current in the circuit crosses zero, the control switch 22 is controlled to be switched off for a predetermined interval, the low-voltage switching power supply unit 241 obtains the power in the predetermined interval and regulates the power to be transmitted to the non-sleep communication unit 23, that is, the low-voltage switching power supply unit 241 obtains the power for switching off the load 100 for a short time in the operating state, so as to operate the non-sleep communication unit 23, and selects to switch off in a range with a small voltage at the zero-cross point position, and the switching-off moment is short, so that the normal operation of the load is not affected, for example, the lamp does not flicker. For example, the low-voltage switching power supply unit 241 can be a BOOST type converter, such as a BOOST type converter, so that the obtained voltage is small, but the voltage provided to the non-sleep communication unit 23 is high, or the non-sleep communication unit can continue to operate normally in a state of obtaining an extremely low voltage. For example, the electric energy obtained by the low-voltage switching power supply unit 241 is stored in the energy storage module 234, and is used for operating the non-sleep communication unit 23, for example, at least for operating the non-sleep communication unit 23 to the next period, the control switch 22 is turned off again for a predetermined interval, and after the low-voltage switching power supply unit 241 obtains the electric energy again, repeatedly, the low-voltage switching power supply unit 241 and the energy storage module 234 cooperate to continuously supply power to the non-sleep communication unit 23 when the control switch 22 is in the closed state and the load 100 is operating.

In other words, when the control switch 22 is turned off, the input current is regulated to the non-sleep communication unit 23 by the current of the switching power supply unit 24, and a part of the smaller current is transmitted to the load 100 to form a closed circuit, for example, a low-power closed circuit is formed between the zero line and the live line, in which the current is mainly used for maintaining the operation of the non-sleep communication unit 23, so that the current passing through the load 100 is smaller, and thus the load 100 is not operated, such as the situation that the lamp flickers and shines. Therefore, the non-sleep communication unit 23 can obtain the operating power to continuously receive the signal transmitted by the motion control device 10 regardless of whether the load 100 is in the operating state or the load 100 is in the non-operating state, so that it is not necessary for the motion control device 10 to transmit a long signal, and the series control device 20 can accurately receive the signal transmitted by the motion control device 10, and thus the phenomenon of control inflexibility does not occur. It should be mentioned that, when the control switch 22 is closed or closed at the instant, the switch power supply unit 24 obtains the electric energy at the instant when the control switch 22 is closed, supplies the non-sleep communication unit 23 and the switch driving unit 25 to work, that is, before the electricity-taking control unit is the non-sleep communication unit 23 and the switch driving unit 25 supplies electricity, the switch power supply unit 24 continues to supply electricity to the non-sleep communication unit 23 and the switch driving unit 25, thereby ensuring that the non-sleep communication unit continuously works without sleep.

The switching power supply unit 24 is, for example and without limitation, a switching power supply module, and of course, the switching power supply unit 24 can also be another power supply adjusting device, for example, the switching power supply unit 24 is a step-down AC-DC converter, such as a BUCK converter, for example and without limitation, the voltage output by the switching power supply unit 24 is in a range of 1.5-24V. The low-voltage switching power supply unit 241 is a BOOST type AC-DC converter, such as a BOOST type converter, and the voltage range output by the low-voltage switching power supply unit 241 is 1.5-24V.

In some embodiments of the present invention, the low-voltage switching power supply unit 241 is a pulse-taking type buck converter, and the switching power supply unit 24 is a buck converter.

In some embodiments of the invention, the voltage regulation module is selected from the group consisting of: one of a BUCK type DC-DC converter, a BOOST DC-DC converter, and an LDO regulator.

In some embodiments of the invention, the communication module is an integrated circuit with high frequency receiving and/or transmitting functionality.

In some embodiments of the present invention, when the time of the control signal transmitted by the mobile control device 10 does not exceed 50ms, the serial control device 20 makes an immediate response to control the operation of the load 100 without affecting the operating state of the load 100.

In some embodiments of the present invention, the control switch 22 is a semiconductor switching device.

Fig. 14 is a schematic perspective view of a series control apparatus 20 according to a sixth embodiment of the present invention.

In this embodiment of the present invention, the mobile control device 10 includes a plurality of the buttons 11, and the serial control device 20 controls the operation of a plurality of the loads 100 respectively, that is, the circuit control system is applied to a control loop for operating a plurality of the loads 100.

Further, the series control device 20 includes a plurality of control switches 22, and each control switch 22 is configured to control the on/off of the circuit between the power-taking control unit 21 and the corresponding load 100. That is, when the series control device 20 is switched into the load 100 circuit, each control switch 22 is disposed between the power-taking control unit 21 and the load 100. When the corresponding load 100 needs to work, the control switch 22 is closed, so that the current passing through the power-taking control unit 21 is transmitted to the load 100 through the control switch 22, so as to work the corresponding load 100. When the load 100 does not need to work, the corresponding control switch 22 is turned off, that is, the current passing through the power-taking control unit 21 cannot reach the load 100 through the control switch 22. In other words, the branch in which the control switch 22 is located provides the load 100 with a current in an operating state, for example, a current up to a rated power operation, when a current reaches the load 100 through the control switch 22, the load 100 can operate normally, and when a current does not reach the corresponding load 100 through the control switch 22, the load 100 does not operate or the load 100 is in a state far below the rated power.

In some embodiments of the present invention, a plurality of the control switches 22 are driven by one of the switch driving units 25, and one of the switch driving units 25 controls the operation of a plurality of the control switches 22, and thus the operation of a plurality of the loads 100. In other embodiments of the present invention, the series control apparatus 20 may include a plurality of the switch driving units 25, each of the switch driving units 25 respectively drives a corresponding control switch 22, and it should be understood by those skilled in the art that the corresponding control modes of the driving units and the control switches 22 are not limited by the present invention.

Referring to fig. 15, a schematic diagram of a circuit control system according to a seventh embodiment of the invention is shown. In this embodiment of the present invention, the circuit control system includes a plurality of the mobile control apparatuses 10, a plurality of the tandem control apparatuses 20, and includes a back-end gateway 30, and the back-end gateway 30 integrally manages the operations of a plurality of loads 100 controlled by the plurality of the mobile control apparatuses 10 and the plurality of the tandem control apparatuses 20.

Further, each of the mobile control apparatuses 10 is directly connected to each of the series control apparatuses 20 in communication, and the back gateway 30 is connected to each of the series control apparatuses 20 in communication, and feeds back control information to each of the series control apparatuses 20 to coordinate operations of the plurality of series control apparatuses 20, that is, to coordinate operations of the plurality of loads 100. For example, during the operation, each of the mobile control devices 10 sends a signal to each of the series control devices 20, the series control devices 20 further transmit the information to the back gateway 30, and the back gateway 30 feeds back the information to each of the series control devices 20 according to a pre-established control manner, so as to control the cooperation of each of the loads 100 according to a predetermined requirement.

Further, the rear gateway 30 may form a load control system, for example, a load control system that can be mounted on a mobile device is formed, and further, the mobile device may control the operation of a plurality of loads in a manner of setting an application APP on the mobile device side, or preset the operation modes of a plurality of loads. For example, the back gateway 30 may manage any plurality of series control devices 20 connected in series with the luminaires, so as to form scene control, that is, implementing combined on-off control on a plurality of luminaires through the cloud or app, for example, there are 10 lights, in some scenes, lights 1, 3, 5, 7, and 9 are required to be turned on, others are required to be turned off, and in some time periods, lights 2, 4, 6, 8, and 10 are also required to be turned on, so as to implement a preset grouping scene control function.

Referring to fig. 16, according to the above embodiment of the present invention, the present invention provides a circuit control method, comprising:

receiving a control signal through a serial control device 20 without sleep; and

the operation of a load 100 is controlled in series by the series control device 20 in accordance with the control signal.

In the circuit control method, the mode of sending the control signal from the power generation place and the mode of controlling the load 100 to work in series are combined, so that the advantages of the power generation and the series control can be combined with each other, the control signal can be completely received, and the sensitive control can be realized.

Further, in the step of sending the control signal from the self-generating device, the pairing code can be sent, so that the two controlled ends can be accurately paired and controlled, namely, one controlled end corresponds to the other controlled end.

The control signal is received without sleep, so that the transmitted control signal can be completely received, and the control signal can be received by a long terminal or a short terminal.

Further, in the step of controlling the operation of the load 100 in series, when the load 100 is in the non-operation state, the series control device 20 is in the low power operation state.

In the step of receiving the control signal through the series control device 20 without sleep, the current or voltage parameter in the circuit is monitored, a second half-cycle control element 212 is controlled to be turned off in a predetermined interval, and electric energy on two sides of the second half-cycle control element 212 is obtained for the operation of a sleep-free communication unit 23.

In the step of receiving the control signal through the series control device 20 without sleep, the power supplied to the sleep-less communication unit 23 is adjusted to operate at low power.
