Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
The technical means of the present invention will be described in detail with reference to specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The existing intelligent controller generally adopts indicator lights with different colors to emit light to indicate different working states, for example, a three-channel intelligent wall switch, and a corresponding indicator light needs to be arranged on a key corresponding to each channel to indicate the power supply state of a load controlled by the channel. The inventor of the present invention finds that a control channel of an intelligent controller at least corresponds to two power supply states of "on" and "off", so that one control channel at least needs two indicator lamps for status indication, and further, a driving port for controlling the indicator lamps is seriously insufficient when the number of control channels is large. In addition, the inventor finds that similar to the intelligent controller of the intelligent wall switch, each control channel only lights one color of indicator light at the same time, and the indicator lights of multiple colors are not lighted at the same time. Based on this, in an embodiment of the present invention provided by the inventor, a status indicating device is provided, which is applied in the intelligent controller 10 to optimize the number of driving ports of the intelligent controller 10 for controlling the indicator light, so as to solve the problem of insufficient number of driving ports.
Referring to fig. 1-11, a status indicating device according to the present invention is specifically illustrated based on fig. 1-11; specifically, as shown in fig. 1, a schematic circuit structure diagram of a status indication apparatus according to an embodiment of the present invention is shown; it can be seen that the status indication means comprise at least:
a driving assembly 1 for outputting a driving voltage;
the indication unit 200 includes:
a first indicator 201, electrically connected to the driving assembly 1, for sending a first indication signal in response to the driving voltage;
a second indicator 202 electrically connected to the driving assembly 1 and the first indicator 201 and configured to extinguish the first indicator 201 when a second indication signal is issued in response to the driving voltage; the first indication signal and the second indication signal can be understood as light signals of different colors, for example, the first indication signal is a blue light signal, and the second indication signal is an orange light signal; the electrical connection is understood to be a direct electrical connection or an indirect electrical connection, wherein the indirect electrical connection can be, for example, an electrical connection after passing through at least one of a current limiting circuit, a filter circuit, an amplifying circuit or a rectifying circuit; the extinguishing is to be understood as failing to send out an optical signal sufficient to form an indicating effect, including that the first indicating member 201 is completely extinguished due to power failure, and also including that the first indicating member 201 has insufficient driving voltage and fails to send out an optical signal sufficient to form an indicating effect, so as to achieve the extinguishing in a visual state;
the driving assembly 1 comprises N +1 driving ports A 1 ～A N+1 N indication units 200 are provided, and are used for corresponding to N control channels of the intelligent controller 10 one by one; all the first indicators 201 of the N indicating units 200 are directly or indirectly controlled by the driving port a of the driving assembly 1 1 The second indicators 202 of the N light-emitting indication units 200 are sequentially controlled by the driving port a of the voltage control unit 300 directly or indirectly 2 ～A N+1 So that N number of the indication units 200 can respond to different driving voltages output by the driving assembly 1 to change the indication signal sent by each indication unit 200, where N is an integer greater than or equal to 1.
The number of the indication units 200 is N, and is used to correspond to the N control channels of the intelligent controller 10 one to one, and it should be understood that: one indication unit 200 corresponds to only one control channel, one control channel also corresponds to only one indication unit 200, and the number of the control channels is the same as that of the indication units 200 so as to form a one-to-one corresponding position relationship. The indication signal sent by the change indication unit 200 includes switching the indication unit 200 from sending the first indication signal to sending the second indication signal, or switching from sending the second indication signal to sending the first indication signal, including simultaneously changing the indication signals of a plurality of indication units 200, and also including changing the indication signal of only one indication unit 200. In addition, the reference numeral A 1 ～A N+1 Only used for labeling the driving ports in the driving assembly 1 for the convenience of the following description, and not used for limiting the actual number of interfaces included in each driving port (for example, when the driving assembly is implemented as a single chip, a 1 The port may be a driving port formed by an input/output port of the single chip microcomputer, or may be one or more driving ports formed by a plurality of input/output ports, which is not limited in this embodiment) and an actual physical arrangement sequence, where the driving ports are arranged in the driving assembly 1 in sequence, arranged in the driving assembly 1 at intervals, or arranged in sequenceThe irregular arrangement in the driving assembly 1 does not depart from the protection scope of the present embodiment, which is not limited by the present embodiment.
In the embodiment of the present invention shown in fig. 1, this embodiment utilizes the application characteristic that the switch indicator of the intelligent controller 10 only needs to illuminate an indicator of one color at the same time, and proposes a status indicator, which drives all the first indicators 201 through one driving port, respectively drives each of the second indicators 202 through a plurality of other driving ports, and sets the illumination of the first indicators 201 to be controlled by the second indicators 202, that is, when the second indicators 202 are illuminated, the corresponding first indicators 201 can be passively extinguished, and then 2N indicators can be controlled through N +1 driving ports, thereby reducing the number of driving ports used, optimizing the utilization rate of the driving ports, and solving the problem of shortage of the driving ports. In addition, in the embodiment of the present invention, the passive control end of the first indicator 201 is directly or indirectly connected to the active control end of the second indicator 202, so that the first indicator 201 and the second indicator 202 cannot be simultaneously lighted by the voltage control device at any time during operation, so as to form a hardware foolproof function of the status indicator, thereby preventing the abnormal status of the indicator light caused by the confusion of the control program in the driving assembly 1.
In some embodiments, the second indicator 202 includes a second control end electrically connected to the drive port A of the drive assembly 1 directly or indirectly 2 ～A N+1 To be capable of being driven by the driving voltage to issue a second indication signal; the first indicator 201 includes: a first control terminal 2011 electrically connected to the drive port A of the drive assembly 1 directly or indirectly 1 The driving circuit is driven by the driving voltage to send out a first indication signal; the third control end 2012 is electrically connected to the second control end 2021 of the second indicator 202 directly or indirectly, so that the first indicator 201 can be extinguished when the second indicator 202 sends the second indication signal. As shown in fig. 2, a detailed circuit structure diagram of the embodiment of the present invention is given; n indicating units 200 are provided, and the voltage control unit 300 is provided withThere are at least N +1 drive ports A 1 ～A N+1 (ii) a The first control terminals 2011 of the N first indicators 201 (first indicators 2011-first indicator 201N) in each indicating unit 200 are electrically connected to a 1 The port is controlled by A 1 The driving voltage outputted from the port is turned on or off, and the third control terminals 2012 are respectively connected to the second control terminals 2021 corresponding to the second indicators 202; the second control terminals 2021 of the N second indicators 202 (the second indicators 2021 to the second indicators 202N) in each indicator unit 200 are electrically connected to a in sequence 2 ，A 3 ,…,A i ，…,A N+1 The ports are controlled by the ports A respectively 2 ～A N+1 So that: the voltage control unit 300 can control 2N indicators (including the first indicator 201 and the second indicator 202) through N +1 driving ports; it should be noted that, in fig. 2, only the control ports of the first indicator and the second indicator in the first indicator unit 200 are labeled, and other indicator units are not labeled, and the ports of the indicators in the other indicator units are similar to the ports in the first indicator unit 200, and can be understood by referring to the labels in the first indicator unit 200.
According to the technical scheme provided by the embodiment, the voltage control device cannot light the first indicator 201 and the second indicator 202 at any time in operation based on the design of a hardware layer, so that the hardware fool-proofing function of the state indicating device is formed.
As shown in fig. 3, a specific implementation circuit diagram of the indicating unit 200 of the present embodiment is given, where the first indicating element 201 is implemented as the first light emitting diode D1 in fig. 3, and the second indicating element 202 is implemented as the second light emitting diode D2 in fig. 3; an anode of the first light emitting diode D1 is formed as a first control terminal of the first indicator 201, and a cathode thereof is formed as a third control terminal of the first indicator 201; the anode of the second light emitting diode D2 is formed as the second control end of the second indicator 202; the first light emitting diode D1 and the second light emitting diode D2 have different light emitting colors. Specifically, an anode terminal of the first light emitting diode D1 is electrically connected to the voltage control unit 300 directly or indirectly, a cathode terminal of the first light emitting diode D1 is electrically connected to an anode terminal of the second light emitting diode D2, and a cathode terminal of the second light emitting diode D2 is grounded; furthermore, when the voltage control unit 300 applies the first voltage and the second voltage alternately to the first light emitting diode D1, the first light emitting diode D1 generates a light emitting signal as the first indication signal, and when the voltage control unit 300 applies the third voltage to the second light emitting diode D2, if the second light emitting diode D2 is desired to be turned on, the third voltage is necessarily at a high level, which causes the cathode terminal of the first light emitting diode D1 to be at a high level, so that the first light emitting diode D1 is turned off, and further, the first indicator 201 and the second indicator 202 cannot be simultaneously driven to emit light regardless of the driving voltage output by the voltage control unit 300, thereby preventing the abnormal state of the indicator lamp (for example, the orange lamp and the blue lamp) caused by the program disorder in the voltage control unit 300. The first light emitting diode D1 and the second light emitting diode D2 may be two light emitting diodes separately arranged (as shown in fig. 4), or may be two-color light emitting diodes packaged together (as shown in fig. 4).
In the embodiment of the invention shown in fig. 2-4, the drive assembly 1 is driven through a drive port a 1 The first control terminal 2011 for controlling the N first indicators 201 via the N driving ports A 2 ～A N+1 The second control ends 2021 of the N second indicators 202 are respectively controlled, and then the third control end 2012 of the first indicator 201 in each indicator unit 200 is connected to the second control end 2021 of the corresponding second indicator 202, so that the first indicator 201 in each indicator unit 200 is simultaneously controlled by the driving assembly 1 and the second indicator 202, when the driving assembly 1 outputs a driving voltage to the first indicator 201 and the second indicator 202 is turned off, the first indicator 201 can be turned on to send a first indication signal, and when the second indicator 202 is turned on, the first indicator 201 is turned off passively, and thus the purpose of controlling 2N indicators (the N first indicators 201 and the N second indicators 202) through N +1 driving ports is achieved, which greatly reduces the control of the indicatorsThe number of the driving ports required by the display element improves the problem that the number of the driving ports for driving the indicator lamp is insufficient when the number of the control channels of the intelligent controller 10 is large. Correspondingly, when the second indicator 202 is lighted, the first indicator 201 is extinguished, and whether the second indicator 202 is lighted or not is controlled by the driving assembly 1 only and is not related to the first indicator 201, so that a hardware fool-proofing effect between the first indicator signal and the second indicator signal is formed. That is, the first indication signal and the second indication signal are isolated from a hardware level (only one of the two signals can be lighted at a time), so as to prevent an abnormal state of the indicator light caused by a driver in the driving assembly 1 being confused (for example, the first indication member 201 and the second indication member 202 are lighted at the same time to cause the first indication signal and the second indication signal to be sent out at the same time).
In addition, the inventor finds that in the prior art, the indicator light of the intelligent controller 10 is generally controlled to emit light or extinguish through simple high and low levels, so that the power consumption and the heat generation of the LED indicator light are high, and the light emitting efficiency and the service life of the LED indicator light have temperature dependence. And the simple and rough control of the illumination of the LED indicator lamp through the continuous output of the high level can cause the LED indicator lamp to generate heat, so that the service life and the luminous efficiency are influenced. Therefore, in this embodiment, in order to further improve the problems of short service life and low light emitting efficiency of the LED indicator in the prior art, a related technical solution is further proposed, and referring to fig. 5, the driving assembly 1 includes:
a selection unit 100 for outputting a selection signal in response to a selection manipulation;
a voltage control unit 300 electrically connected to the selection unit 100, for outputting a driving voltage based on the selection signal;
and the voltage control unit 300 is further configured to form a lighting phase of the indication unit 200 by continuously applying a first voltage to the first indicator 201 in a first period and form a lighting phase of the indication unit 200 by continuously applying a second voltage to the first indicator 201 in a second period when the received selection signal is a first selection signal of the at least two selection signals; wherein the lighting phase and the extinguishing phase sequentially cycle to form a first indication signal of the indication unit 200. Wherein the lighting phase and the extinguishing phase are continuous and cycle in sequence according to a set period and frequency to form a first indication signal of the indication unit 200. The switching frequency of the lighting phase and the extinguishing phase may be set according to actual requirements, and the frequency is generally set to a value that cannot be perceived by human eyes, that is, the indication unit 200 is lighted and extinguished at a higher frequency, but cannot be perceived by human eyes, so as to provide a visual effect that the indication unit 200 is always lighted.
In this embodiment, when the voltage control unit 300 receives the first selection signal, the first voltage is continuously applied to the indication unit 200 in the first period of one cycle, the second voltage is continuously applied in the second period, so that the lighting phase and the extinguishing phase of the indication unit 200 are formed, and the periodic lighting phase and the extinguishing phase are cycled at high frequency to divide the driving process of the indication unit 200, so as to reduce the heat generation and the power consumption of the indication unit 200, and enable the indication unit 200 to extend the service life and uniformly emit light, in other words, the present embodiment suppresses the power consumption of the indication unit 200 by dividing the power supply process of the indication unit 200 into a plurality of continuous lighting phases and extinguishing phases, so as to compensate for the change of the luminous flux of the indication unit 200 caused by the temperature and to extend the service life of the indication unit 200. In one embodiment, the first indicator 201 is implemented as an LED lamp, and the first voltage is greater than the VF voltage of the first indicator 201, such as 3.3V. The second voltage is less than VF voltage of the first indicator 201, for example, 0V voltage. And further, it is possible to suppress power consumption of the first indicator 201 by repeatedly lighting and extinguishing it, for the purpose of stably lighting it and reducing its heat generation.
Further, in some embodiments, in order to achieve the adjustable brightness of the first indication signal, the voltage control unit 300 is further configured to change the duration of the lighting phase according to a received external configuration command sent by the smart terminal 30. Furthermore, the brightness of the first indication signal can be changed to adapt to different brightness requirements. In a specific example, the external configuration command may be a locally triggered command, such as a brightness adjustment button electrically connected to the voltage control unit 300, and the brightness of the corresponding indication unit 200 may be adjusted by triggering the brightness adjustment button. In another example, as shown in fig. 6, the external configuration command may be a remotely triggered command, such as a configuration command sent by the intelligent terminal 30 for adjusting the brightness. Further, the user may adjust the brightness of the pointing unit 200 through an Application interface (app) on the smart terminal 30 (e.g., a mobile phone or a tablet). Specifically, for example, when the external configuration instruction originates from a mobile phone, as shown in fig. 6, for an app interface running on the mobile phone, the brightness may be adjusted by a brightness adjustment slider, the brightness adjustment slider may be manually slid, each position on the brightness adjustment slider corresponds to a duration of a lighting phase, the duration of the lighting phase is shorter when the brightness adjustment slider is stroked to the left, and the duration of the lighting phase is longer when the brightness adjustment slider is stroked to the right, and the duration of the lighting phase when the brightness adjustment slider is stroked to the rightmost end is equal to the duration of a period (that is, when the brightness adjustment slider is fully lit in a period, the brightness adjustment slider is not extinguished any more).
In some embodiments, the first period is less than or equal to the second period by default in one cycle, so that the power consumption and heat generation of the indication unit 200 can be reduced as much as possible, which can prolong the service life and uniformly emit light. In a preferred embodiment, the ratio of the first period to the duration of one cycle is set to 34% by default.
In some embodiments, the voltage control unit 300 is further configured to continuously apply a third voltage to the second indicator 202 when the received selection signal is a second selection signal of the at least two selection signals, so that the second indicator 202 is lighted to form a second indication signal of the indication unit 200; the third voltage is the same as or different from the first voltage.

Corresponding to the N indicating units 200 in the above embodiment, in this embodiment, the selecting unit 100 has N: b is 1 ～B N One-to-one correspondence to N of the indicating units C 1 ～C N (ii) a Wherein the unit B is selected i For outputting a signal corresponding to the indicating unit C in response to the selection manipulation i The selection signal of (1); the value of i is any one of 1 to N. Furthermore, a fast identification of the selection signal is ensured by providing a separate selection unit 100 for each indication unit 200.
The selection signal may be any signal having a selection function, and a plurality of selection signals may be provided, may be a plurality of selection signals that can be generated corresponding to one selection unit 100, may be a plurality of selection signals that can be emitted corresponding to a plurality of selection units 100, or may be all selection signals that can be generated by a combination of both. Furthermore, based on different selection commands, one selection unit 100 may be caused to output a selection signal corresponding to a selection command from among a plurality of selection signals that can be output by the selection unit 100, one selection unit 100 corresponding to a selection command from among a plurality of selection units 100 may be caused to output a unique selection signal that can be output by the selection unit 100, and one selection unit 100 from among a plurality of selection units 100 may be caused to output a selection signal corresponding to a selection command from among a plurality of selection signals that can be output by the selection unit 100.
The selection operation can be a selection operation triggered by an electric signal instruction or a selection operation formed by physical triggering. In one embodiment, the selection instruction may be a selection instruction generated by an operating body (e.g., a human hand, a mechanical arm, etc.) through physical triggering (e.g., pressing, rotating, etc.); specifically, in this embodiment, the selection units 100 include switching elements, and correspondingly, the selection manipulation includes a physical manipulation of selecting a certain selection unit 100 to trigger the corresponding switching element; furthermore, if a certain indication unit 200 currently sends out a first indication signal to the outside, the switch element of the corresponding selection unit 100 outputs a second selection signal that is output to the voltage control unit 300 at the designated level when triggered, and if a certain indication unit 200 currently sends out a second indication signal to the outside, the switch element of the corresponding selection unit 100 outputs a first selection signal that is output to the voltage control unit 300 at the designated level when triggered. As shown in fig. 8, a circuit diagram of the present embodiment is shown, in which the switch element is implemented as a micro switch, and the micro switch is electrically connected to the voltage control unit 300, so as to output a low level to the voltage control unit 300 when the micro switch is triggered, and output a high level to the voltage control unit 300 when the micro switch is not triggered. Of course, in other embodiments, the selection unit 100 may also be implemented as a non-contact switch element such as a hall switch, an infrared switch, or the like, and therefore, the selection unit 100 of this embodiment, which is composed of any electronic component and combination thereof that can be triggered to generate a selection signal (a specified level signal), is within the protection scope of the present invention.
In another embodiment, the selection instruction may be a directional control signal, such as a control signal sent by a mobile phone or a computer through wires or wirelessly, and the control signal has a function of selecting one of the plurality of selection units 100.

Based on the technical solution provided in this embodiment, the user may also select the target indication unit 200 by manipulating the app running on the smart terminal 30 such as a mobile phone to generate a selection instruction, and send the selection instruction to the state indication device (as shown in fig. 10).

Referring to fig. 11, in this specific application scenario, the voltage control unit 300 is implemented as a single chip, the input/output port of the single chip is used as a driving port, and each selection unit 100 is implemented as a micro switch, and each micro switch is electrically connected to the voltage control unit 300, so as to provide a selection signal to the voltage control unit 300 when triggered. For example, the following steps are carried out: selection unit B as in FIG. 11 2 Correspondence indication unit C 2 Then in the selection unit B 2 When the corresponding micro switch is pressed, a low-level selection signal is generated to the voltage control unit 300, so that the voltage control unit 300 indicates the cell C based on the selection signal 2 A driving voltage is applied to drive it to emit light. Thus, the embodiment shown in FIG. 11According to the technical scheme, when a microcontroller such as a single chip microcomputer serves as the voltage control unit 300, 2N indicator lamps can be controlled through N +1 input/output ports. For example, a three-channel wall switch needs 6 LED indicator lamps, and this embodiment only needs 4 LED lamps to control the 6 LED lamps, which saves 2 input/output ports compared to the prior art.
Based on the state indicating device provided in the foregoing embodiment, the present embodiment further provides an intelligent controller 10, and the following describes an embodiment of the intelligent controller 10 according to the present invention.
Referring to fig. 12, an intelligent controller 10 according to an embodiment of the present invention includes a status indication device according to the above embodiment; and the number of the first and second groups,
and each control channel is correspondingly provided with one indicating unit 200 for indicating the working state of the control channel.

Further, in an embodiment, the manipulation member includes a key, the applying operation includes an operation of pressing the key, and the selecting operation includes a physical triggering operation applied to the selecting unit 100 by the key being pressed. For example, there are three selection units 100100, namely a first selection unit 100100, a second selection unit 100100 and a third selection unit 100100, and the control member includes three keys, namely a first key corresponding to the first selection unit 100100, a second key corresponding to the second selection unit 100100 and a third key corresponding to the third selection unit 100100.
Further, in some embodiments, as shown in fig. 12, the intelligent controller 10 further includes a switch unit for connecting the load device 20 to switch the power supply loop of the load device 20; each switch unit forms a control channel for intelligently controlling the switch unit; each switch unit is directly or indirectly electrically connected with the voltage control unit 300 to switch the on-off state of the power supply loop of the load device 20 under the control of the voltage control unit 300; the voltage control unit 300 is configured to turn on the corresponding switch unit to supply power to the corresponding load device 20 when the selection signal is the second selection signal.
In a specific example, the switch unit includes a relay, the voltage control unit 300 is electrically connected to the relay through an amplifying device to drive the relay to be turned on and off, when the relay is turned on, the load device 20 connected to the control channel where the relay is located is powered, and when the relay is turned off, the load device 20 connected to the control channel where the relay is located is powered off. Of course, the switch unit may also be implemented as other electronic components with an on-off control function, such as a triode, a MOS transistor, etc., without affecting the implementation of the embodiment of the present invention.
Further, in some embodiments, the smart controller 10 is configured to: when the load device 20 corresponding to the control element is in a power-off state, the first indication signal is sent out through the control element to serve as a backlight of the intelligent controller 10; when the load device 20 connected with the control channel is in a power-off state, a second indication signal is sent out. In the use process of the intelligent controller 10, the backlight is in a long-time lighting state, so that the controller generates heat, the controller can stably emit light, and the service life of the controller is prolonged. With the progress of technology, the service life of the intelligent controller 10 such as a wall switch, a wireless switch, etc. is longer and longer, so the service life of consumables which cannot be replaced and need to be synchronized is also increased, and the LED indicator is a consumable which cannot be replaced, so that the situation that the switch button is not broken and the lamp is broken and cannot be indicated often occurs, so the service life of the LED indicator needs to be prolonged as much as possible to match the whole service life of the switch, and since the first indicator 201 is used as a backlight of the intelligent controller 10, the light emitting time of the first indicator 201 is generally longer than that of the second indicator 202, the power consumption of the first indicator 201 is reduced by intermittently lighting, so that the service life of the first indicator is prolonged as much as possible to be the same as that of the second indicator 202, and the use of the intelligent controller 10 is prevented from being influenced by premature damage.

In addition, referring to the above embodiment, the first indication signal may be a blue light signal, and the second indication signal may be an orange light signal. Further, when receiving a local selection instruction or a selection signal sent by the intelligent terminal 30, the intelligent controller 10 switches the power supply state of the load device 20, and sends a first indication signal or a second indication signal to the outside, which is specifically exemplified as follows:
when the load device 20 controlled by a certain control channel of the intelligent controller 10 is currently in the power-off state, the indicating unit 200 corresponding to the control channel externally sends a blue light signal (i.e., a first indicating signal) as a backlight light to inform a user that the load device 20 controlled by the control channel is currently in the power-off state. If the intelligent controller 10 receives a selection instruction brought by pressing a key corresponding to the control channel (local physical triggering) or sending a control signal (remote triggering) by the intelligent terminal 30, the switching element (relay, MOS transistor, etc.) corresponding to the control channel is controlled to be turned on to switch the power supply state of the load device 20 to the power-on state, and at the same time, the indicating unit 200 corresponding to the control channel is controlled to be switched to output an orange light normally-on signal (i.e., a second indicating signal) to inform a user that the load device 20 connected to the control channel is currently in the power-on state. Correspondingly, when the load device 20 controlled by a certain control channel of the intelligent controller 10 is currently in the power-on state, the indicating unit 200 corresponding to the control channel sends out an orange light normally-on signal (i.e., the second indicating signal) as the status indicator light of the control channel, so as to inform the user that the load device 20 controlled by the control channel is currently in the power-on state. If the intelligent controller 10 receives a selection instruction caused by pressing a key corresponding to the control channel (local physical triggering) or a control signal (remote triggering) sent by the intelligent terminal 30, the switching element (relay, MOS transistor, etc.) corresponding to the control channel is controlled to be turned off to switch the power supply state of the load device 20 to the power off state, and at the same time, the indicating unit 200 corresponding to the control channel is controlled to be switched to output a blue light signal (i.e., a first indicating signal) as a backlight lamp to inform a user that the load device 20 connected to the control channel is currently in the power off state.
