Description

FIELD OF THE INVENTION

The present invention relates to an energy-saving switch, and more particularly, to an energy-saving switch that can prevent the sensor from detecting a user’s proximity by stopping the sensor when the user turns on the electrical device manually when entering a predetermined area, such as a toilet, and which can automatically turn off the electric device by operating sensor when the user leaves a given area, or prompts the user to stop the operation of the electrical device manually, giving a certain sound.

State of the art

In recent years, in Korea, the amount of energy used for lighting reaches 18% of the total amount of electricity consumed and increases significantly every year in accordance with the high quality of living. Currently, in accordance with the worldwide trend of environmental protection, there are very positive attempts to reduce environmental pollution through the efficient use of electricity by increasing energy efficiency in lighting and reducing electricity consumption.

Basically, the most universally used electrical devices are incandescent, fluorescent, and so on.

Since a conventional lighting system using such an electrical device is provided with a power switch that is turned on or off only by manually manipulating the user when the switch is in the “on” state when there are no users, electricity is wasted due to continuous lighting. In addition, there is another problem in a standard lighting system, namely that the user must manipulate the switch every time to turn on or off the electrical device.

Such problems can be resolved to a significant degree through the recently proposed human detection lighting system.

A lighting system with a person’s detection, which is installed in an area often used by people, such as the entrance, outer entrance door, hallway, stairs, approach to the elevator, warehouse or others, automatically turns on the electrical device when the illumination is below a predetermined value and when to the specified the area enters the user, and turns off the electrical device when the illumination is above a predetermined value and when the user is not in the specified area. The lighting system with human detection provides the lighting operation without manipulating the switch by the user each time to increase usability, and prevents the consumption of electricity to enable its efficient use.

A human detection lighting system will be described in more detail. The lighting system detects infrared radiation (6.5 □ ~ 15 □) generated by the human body, detects the movement of the human body within the detection range over a long distance using a non-contact type pyroelectric sensor, transmits infrared radiation emitted by the human body to the pyroelectric type infrared sensor through a Fresnel lens and transmits the output voltage of the sensor to the first amplifier circuit. The first amplifier circuit serves as a bandpass filter and amplifier and has a gain level of about 40dB. The first amplified small signal is transmitted to the second amplifier circuit through a coupling capacitor, and the signal output from the second amplifier circuit is transmitted to a two-threshold comparator. When outputting a signal equal to a predetermined voltage or more, a square wave is output so that the electrical device is turned on or off through the synchronization circuit and the triac on / off circuit.

The triac on / off circuit contains a light sensor having a CDS element, which is made of a material containing a mixture of cadmium (Cd) and sulfur (S), the resistance of which decreases rapidly when light is detected in a predetermined amount and the resistance of which increases to several hundred ohm (Ω). Therefore, the triac on / off circuit can provide appropriate illumination by selectively opening and closing the circuit in accordance with the change in illumination.

As described above, a human detection lighting system having the operating principle described above cannot function normally if any of the above elements are omitted and cannot be used in an isolated area such as a toilet. That is, when the user enters the toilet, a lighting system with human detection detects the user and turns on the electrical device. After that, when the user's movement is not detected in a given area, the lighting system with the detection of a person turns off the electric device automatically after a predetermined period of time, and as a result, the person's sense of natural anxiety increases.

In addition, the lighting system with human detection provides convenience for the user by automatically turning on and off automatically, but has the disadvantage that the user cannot simply turn the electric device on or off manually in accordance with the desired intentions when it is necessary to turn on the electric device in conditions where the light sensor detects an illumination that is higher than a predetermined illumination value. In addition, the lighting system with human detection has several drawbacks in that, due to the frequent switching on and off, the service life of the electric device is reduced when there is an excessive change in light due to rapid changes in weather, in addition, the light sensor often acts mistakenly, and when the light sensor loses its functionality, the entire lighting system with the detection of a person should be replaced.

Additionally, as described above, since the CDS element used for the light sensor is made of a material containing cadmium (Cd) and sulfur (S), which is harmful to the human body and environmentally disadvantageous, a human detection lighting system has another problem , consisting in the fact that the composition must be assembled and processed separately.

A CDS element is used for the light sensor, however, there is an electrovacuum photocell, a phototransistor, a photodiode, and so on, which provide an action similar to a CDS element. But they cannot be used for a lighting system with human detection, as they are too large and massive, increase production costs, as they are too expensive, and cannot be used in a lighting system with detection of a compact type of person. In addition, since they do not provide the principle for opening or closing the corresponding circuit in accordance with the increase and decrease of the resistance value, like a CDS element, but provide the principle for generating an electric current in accordance with the dose of light emission, the user should carefully use the lighting system from - due to the discharge of electricity, and therefore, they cannot be used for a lighting system with human detection.

Therefore, a lighting device is required in which a light sensor can be omitted, which can turn the electrical device on or off automatically and / or manually to improve usability, which can prevent waste of electricity even if the electrical device is turned on or off manually, in which it can be used. various sensors, in addition to an infrared sensor, for detecting a moving body and which provides a simple structure and improved circuitry nick, thereby substantially reducing the error rate and cost.

Description of preferred embodiments of the invention

Embodiment 1

The energy-saving switch comprises an input / output unit 100 (FIGS. 1 and 2), an electric device 200 electrically connected to the control means 110, which is contained in the input / output unit 100, and a sensor 300 electrically connected to the control means 110.

The input / output unit 100 comprises an input 120, a sound output 130, an indicator 140, light emitting elements 150, and control means 110 electrically connected to an input 120, a sound output 130, an indicator 140, and light emitting elements 150 for general control thereof.

As input 120, an electronic touch button, such as a touch keypad or a mechanical push button switch of the form of a physical contact point, is used. Input 120 (FIG. 2) comprises an automatic push button switch 121 and a manual push button switch 122. The automatic push button switch 121 and the manual push button switch 122 are made in the form of a conventional button with a single keystroke. Sound output 130 is a regular speaker. The indicator 140 contains several light emitting elements, such as lamps or LEDs (light emitting diodes), which can convert an on state and an off state. One of the light-emitting elements shines in red and the other shines in green.

The energy-saving switch contains a frame 101 (figure 2), mounted on the outer surface of the wall of the toilet door, the frame 101 is equipped with a junction box 102, which is partially hidden and fixed on it, control means 110 located in the junction box 102, input 120, sound output 130 and an indicator 140 located on the front surface of the junction box 102 and electrically connected to the control means 110. The light emitting elements 150 are mounted on an automatic push button switch 121 and a manual push button switch 122.

At the same time, the indicator 140 contains elements 141 and 142 indicating the state to be applied, and the junction box 102 contains elements 103 and 104 indicating symbols installed in positions adjacent to elements 141 and 142 indicating the state and corresponding to elements 141 and 142. How described above, element 141 emits green light, and element 142 emits red light.

Figure 2 does not show the control means 110, which is located inside the junction box 102 or is designed in a micom circuit. Next, according to Fig.6, will be described in more detail the operation of an energy-saving switch containing means 110 of the control.

When the user presses the automatic push-button switch 121 or the manual push-button switch 122 manually (S101), the control means 110 supplies electric power to the electric device 200 (FIG. 1) to turn on the electric device 200, which is turned on, while stopping the operation of the sensor 300 by interrupting the supply power to the sensor 300 (S102). The sensor 300 may be one of an infrared sensor, which is a body movement sensor, an optical sensor, a proximity sensor for detecting user proximity and an ultrasonic sensor.

In addition, the control means 110 controls the supply of electricity to the portion 142 indicating the state used, the indicator 140 for turning on the portion 142 indicating the state used, red, which indicates that the user is inside a predetermined area, for example, a toilet (S103).

After that, the control means 110 again supplies electricity to the sensor 300 after a predetermined period of time, for example, after 5-10 seconds, so that the user finishes entering the predetermined area and so that the sensor 300 is re-activated (S104).

When the user leaves the predetermined area, the sensor 300 detects this and transmits a detection signal to the control means 110 (S105).

The control means 110 turns off the element 142 indicating the applied state, the indicator 140 upon receiving the detection signal from the sensor 300 and simultaneously supplies electric power to the element 141 indicating the applied state, green to turn on the element 141 indicating the applied state (S106). In step (S101), when the user presses the automatic button switch 121, in accordance with the control signal of the control means 110, the power supply to the electric device 200 is automatically stopped (S107). On the contrary, when the user presses the manual button switch 122, step (S106) proceeds to the manual mode processing (S110), which will be described later.

After step (S107), in accordance with the control signal of the control means 110, the sound output 130 outputs a specific sound for a predetermined period of time (S108) and then stops the sound output (S109). Steps (S107) and (S108) may be omitted as selected by the manufacturer.

Manual mode processing (S110) is as follows. A sound is made (S111) to inform the user of a turning state of the electric device 200; turn off (S112) manually the electrical device 200; stop the sound output (S113) by means of a manual push button switch.

In the audio output steps (S108 and S111), it is preferable that various sounds are output. In addition, the sound output 130 may output sounds of various kinds. That is, from the output 130 for sound, a common sound signal, melody, natural sound, such as the sound of flowing water, human voices, and so on, can be received. Preferably, such audio information is stored in the control means 110.

The electrical device 200 is manually controlled by the user with an automatic push-button switch 121 or a manual push-button switch 122, while the sensor 300 is designed to fail to detect a user entering a predetermined area and indicating a user exit from the inside to the outside of the predetermined area. As a result, according to the invention, a high sensitivity sensor is not required, and an inexpensive body movement sensor that can only detect the body can be used.

Embodiment 2

The indicator 140a (FIG. 3) comprises transparent or translucent transmission panels on which predefined symbols are printed, and light-emitting elements such as LEDs or small lamps installed inside the transmission panels, improving visual recognition for the user. In addition, since predefined symbols are printed on the transmission panels, the element 141a indicating the applied state has a green transmission panel, and the element 141b indicating the applied state has a red transmission panel. Recognition can be maximized through color contrast. Additionally, the present invention can increase visual recognition for the user, mainly at night, as can be improved recognition efficiency of the elements 103 and 104 indicating the characters.

Embodiment 3

4, the structure of the indicator is omitted, and an automatic push-button switch 121a and a manual push-button switch 122a of the input 120a are used as an indicator.

The automatic push button switch 121a and the manual push button switch 122a are made of light-transmitting material, and light emitting elements are placed therein. In addition, the automatic push button switch 121a has symbols located thereon meaning “automatic button switch” and the symbols indicated on the transmission panel of the indicator described above, and the manual button switch 122a has symbols located on it indicating “manual button switch” .

When a user presses the automatic push button switch 121a or the manual push button switch 122a, the light emitting element located in the automatic push button switch 121a is turned on, and characters printed on the automatic push button switch 121a are displayed so that the automatic push button switch 121a or the manual push button switch 122a serves as indicators. After that, according to the aforementioned principle of operation for the automatic state “off” or the manual state “off” of the electrical device, the light emitting element contained in the manual push button switch 122a is in the “on” state, and the light emitting element contained in the automatic button switch 121a, is in the off state.

Therefore, the present invention has a simplified structure and can increase efficiency.

When the user presses the manual button switch 122 or 122a (Fig. 7), the energy-saving switch system 10 (S10) is started.

After that, the energy-saving switch proceeds to the steps of turning on the electrical device, turning off the sensor, and turning on the indicator by the control means 110 (S10).

Directly, the control means 110 calculates whether a predetermined period of time (t seconds) has passed (S30). The sensor is turned on if the answer in step (S30) is “Yes” (S40), but if the answer in step (S30) is “No”, then the step returns to step (S20).

Therefore, the control means 110 sets a sensor 300 to fail to detect a user input in a predetermined area.

After the sensor 300 is activated by step (S40), the sensor 300 detects that the user has exited a predetermined area (S50), and the sensor 300 transmits a detection signal to the control means 110, and as a result, the indication of the indicating portions of the indicator is converted under the control of the control means 110 (S61). In step (S50), if no object is detected, then the step returns to step (S40) to perform continuous detection.

Simultaneously with step (S61), in accordance with the control signals of the control means 110, a predetermined sound is output from the sound output 130 (S62), and then the energy-saving switch determines whether the user switches the switch off by means of the manual button switch 122 or 122a (S63). If the user turns off the switch, then the energy-saving switch turns off the electrical device and stops the sound (S64) and thereby completes all steps (S70). However, if the user does not turn off the switch, then step (S63) returns to step (S62) for continuously outputting sound for recognition by the user.

Embodiment 4

8, when the switch detects the user in accordance with the detection step (S50), the control means 110 performs the indicator display conversion step (S61) and controls the audio output part 130 to output a specific sound (S62).

After that, the energy-saving switch determines whether the user turns off the switch after listening to the sound output. If the switch is turned off, the energy-saving switch turns off the electrical device and stops the sound output (S64), and therefore completes all steps (S70). However, if the switch is not turned off, the energy-saving switch determines whether a predetermined period of time (t seconds) has passed (S65).

If the answer is “Yes”, the energy-saving switch stops the sound output (S64) and ends all steps (S70), but if the answer is “No”, the step returns to the sound output step (S62) for continuous sound output.

Therefore, even if the electric device 200 is not turned off by the manual button switch 122 or 122a, the energy-saving switch allows the user to recognize the “on” state of the electric device by outputting a certain sound for a predetermined period of time (t seconds). If the user does not press the manual button switch 122 or 122a even after a predefined period of time (t seconds) (for example, from 5 to 20 seconds), then the energy-saving switch considers that the user did not recognize it, and turns off the electrical device and stops the sound output to complete all stages. As a result, the energy-saving circuit breaker according to the present invention can use electricity efficiently.

In addition, the sequence of actions of the system can be changed in various ways. That is, from the sound output, the sound may not be output continuously, but several times at regular intervals for a predetermined period of time, and then the electrical device is turned off and the sound output is stopped, and this is also included in the context of the present invention.

According to Fig. 9, the system starts when the user presses the automatic button switch 121 or 121a (S10), and then the electric device is turned on, the sensor is turned off, and the indicator displays (S20).

After that, the control means 110 calculates whether a predetermined period of time (t seconds) has passed (S30). If the answer in step (S30) is “Yes”, then the sensor is turned on (S40), but if “No”, then step (S30) returns to step (S20).

After the sensor 300 is activated in step (S40), step (S40) proceeds to the detection step (S50) of the sensor 300. In step (S50), when the sensor 300 detects a user when the user leaves a predetermined area, the sensor transmits a corresponding signal to the control means 110, and then the electric device is turned off, and the indicator displays an indication transformed by the control means 110 (S61). In step (S50), if the object is not detected, then step (S50) returns to step (S40) to continuously detect the user's proximity.

After step (S61), the energy-saving switch ends step (S70) after outputting a certain sound for a predetermined period of time in accordance with a control signal of the control (S65).

The present invention provides the user with convenience since there is no need for the user to further manipulate the switch.

Embodiment 5

The sensor 300 of the energy-saving switch according to the present invention can be mounted at an entrance having a door to obtain the aforementioned action in accordance with opening and closing a door (not shown).

The sensor 300 may be a pair of magnetic sensors or proximity sensors, one of which is installed in a certain position near the door, and the other is installed in the area of the door frame corresponding to the aforementioned position.

Magnetic sensors are divided according to the principle of operation into a sensor of the type of magnetized contact point and type of magnetic detection. Under the principle of functioning like a magnetized contact point, two metal plates are placed at a certain distance from each other in the estimated time, but when a permanent magnet or electromagnet approaches, one of the metal plates is magnetized by a permanent magnet so that the metal plates form magnetic contact points, respectively. As a result, the metal plates are connected to each other when applying power to the metal plates.

In the operation of the type of magnetic detection, the metal plate is electrically connected to the control means and is magnetized or not magnetized according to the approximation level of the permanent magnet. When the metal plate is magnetized, the control means detects the corresponding current, and when the current detected by the means of control reaches the preset value (A), the control means opens or closes the corresponding circuit.

Magnetic sensors with the principle of functioning like a magnetized contact point contain a permanent magnet mounted on the door, a metal plate mounted on the door frame in accordance with a permanent magnet, and a solenoid electromagnet electrically connected to the control means 110 in the area adjacent to the metal plate magnetized by a constant a magnet.

The principle of operation will be described in more detail. In the state where the door is closed, since the metal plate magnetized by the permanent magnet and the metal plate adjacent to the magnetized metal plate form a magnetic contact point with each other, there is no function and action.

When the user clicks on input 120, the control means 110 supplies electric power to the electric device 200 and simultaneously supplies electric current to the solenoid electromagnet for a predetermined period of time to induce the formation of magnetic force. Therefore, even if the user opens the door, since two metal plates support the magnetic contact point, there is no function and action.

When the user closes the door, since the magnetized metal plate is a metal plate magnetized by a permanent magnet mounted on the door, regardless of the solenoid electromagnet, the magnetic contact point can be constantly maintained.

After the power supply to the solenoid electromagnet is stopped, when the user reopens the door, the permanent magnet is separated from the magnetized metal plate, and the magnetized metal plate and other metal plate are released from the reciprocal magnetic contact points, and as a result, the power supply to the electric device 200 is stopped. Therefore, magnetic sensors of the type of magnetized contact point have a system sequence identical to the embodiments first to fourth.

Magnetic sensors with the principle of magnetic detection type operation, as described above, comprise a permanent magnet mounted on the door, a metal plate mounted on the door frame in accordance with the permanent magnet and electrically connected to the control means 110, and a solenoid electromagnet located next to the metal plate and electrically connected to control means 110.

The principle of operation will be described in more detail. In a state where the door is closed, the control means 110 detects in the form of an electric current a magnetic force generated in the metal plate by a permanent magnet.

In the state where the door is closed, the metal plate is magnetized by a permanent magnet, and the control means 110 detects a predetermined electric current, but there is no function and action.

When the user clicks on the input 120, as described above, the means 110 supplies electric power to the electric device 200 and simultaneously supplies electric current to the solenoid electromagnet only for a predetermined period of time to induce the generation of magnetic force.

When the user closes the door, the control means 110 continuously detects an electric current by means of a permanent magnet mounted on the door, but there is no function and action.

Therefore, even if the user closes or opens the door, the control means 110, while continuously detecting electric current, cannot detect whether the door opens or closes.

After the power supply to the solenoid electromagnet is cut off, when the user reopens the door, the permanent magnet is separated from the metal plate, and the control means 110 does not detect an electric current in accordance with the above function and action, so that the control means 110 automatically cuts off the power supply to the electric device 200 Therefore, magnetic sensors of the type of magnetic detection have a system sequence identical to the first to fourth.

The magnetic sensor used in the present invention can be modified in various ways. The magnetic sensor may implement a type of magnetized contact point, a type of magnetic detection, or a type where the type of magnetized contact point and the type of magnetic detection are combined. A magnetic sensor using a magnetized contact point is designed to turn off the electrical device automatically and / or manually, and a magnetic sensor using magnetic detection is designed to output sound and display or change the indication of indicator 140.

Therefore, the present invention can provide sensors of lower cost in order to significantly reduce the cost and to develop a sensor in various ways in accordance with the intention of the manufacturer.

5 and 10, the energy-saving switch 10a has the structure of a third embodiment of the invention and further comprises a disk dialer 161 located under the junction box 102a. The disk dialer 161 allows a user to manually set a time setting unit 160, such as a timer. The time setting unit 160 is electrically connected to the control means 110, and a level indication part 162 is printed on the face of the junction box 102a in accordance with the disk dialer 161 so that the user can set the time by rotating the disk dialer 161.

The time setting unit 160 may be set in accordance with the intention of the user and improves usability, as it is used to set the stopping time of the operation of the sensor 300 as described above.

5, a disk dialer 161 is shown, but a digital input type setting button and a display unit for displaying an appropriate level can be implemented. In addition, in the state where the installation reference time is entered (for example, from 5 to 10 seconds), a reset button can be added so that when the user presses the reset button, the installation time is reset to the installation reference time.

Embodiment 7

11 and 12, the energy-saving switch 10b comprises control means 110 and a sensor 300 electrically connected to the control means 110. The control means 110 is electrically connected to the electric device 200 and is powered by an external power source.

According to Fig. 12, a principle of operation of an energy-saving circuit breaker will be described in more detail. When the sensor 300 detects a moving body or door opening, it transmits a detection signal to the control means 110 (S1). In step S1, the control means 110 controls the electric device 200 to automatically turn it on (S2) and at the same time to stop the operation of the sensor 300 for a predetermined period of time (S3). Thereafter, the control means 110 converts the sensor 300 into a switch-off sensor after a predetermined period of time has elapsed in the automatic switch-on step (S4).

After a predetermined period of time when the sensor 300 detects a moving body or door opening, the sensor transmits a corresponding signal to the control means 110 (S5), and then the control means 110 controls the electric device 200 to turn it off automatically (S6) and simultaneously stops the operation of the sensor 300 for a predetermined period of time (S7). At this time, the sensor 300 is converted to an on sensor (S8), and then step (S8) returns to the aforementioned step (S1) to continuously detect a moving body or open the door and perform automatic on and off.

In steps (S3) and (S7), the control means stops the sensor during the delay time (for example, 5-10 seconds) caused by the user who puts on slippers or opens and closes the door when the user enters or leaves a predetermined area such as a toilet. As a result, during the delay time, the control device does not receive from the sensor a signal to detect a moving body or to open and close the door, as a result of which the automatic and repeated switching on and off of the electric device is prevented.

Steps (S3) and (S7) may be omitted when an energy-saving switch is used in an open hallway.

When the sensor 300 first detects a moving body or door opening, the control means 110 automatically turns on the electrical device, simultaneously stops the operation of the sensor 300 for a predetermined period of time to prevent the sensor from approaching the user when the user enters a predetermined area, and then the sensor 300 is converted to a sensor shutdown after a predetermined period of time from the first detection stage.

When the sensor 300 detects a moving body or door opening a second time, the control means 110 automatically turns off the electrical device, and at the same time, the sensor 300 is converted to an on sensor, and as a result, the electric device 200 can be automatically turned on and off.

The energy-saving switch, according to this embodiment, may comprise at least one element selected from the group consisting of an input, an indicator, an output for sound, and a time setting unit, which are described in the first to sixth embodiments. Since this embodiment has an operation principle identical to the aforementioned embodiments, the operation principle of this embodiment will not be described.

If the energy-saving switch of this embodiment comprises an input 120 or 120a, then the energy-saving switch can be converted to automatic mode or semi-automatic mode when the user presses the automatic button switch 121 or 121a or the manual button switch 122 or 122a for a predetermined period of time.

As described above, according to the first to fourth and sixth embodiments, the energy-saving switch can be installed in various positions, such as an open entrance without a door (for example, an entrance located between the living room and the kitchen), a closed entrance with a door , entrance hall, front door and so on. The fifth embodiment can be applied to a closed type entrance with a door (for example, a toilet, a training room, an indoor room, and so on).

In addition, the energy-saving switch according to the present invention can be changed in various ways. That is, certain portions of the first to sixth embodiments can be applied selectively, and this is included in the context of the present invention.

Option exercise 8

In this embodiment, the energy-saving switch can be automatically turned on and off by the sensor 300, providing ease of use for multiple users.

14, the energy-saving switch according to the present invention comprises a sensor 400 having a first body movement sensor 410 and a second body movement sensor 420, a manual switch 500 and control means 110 electrically connected to the sensor 400 and manual switch 500. The control means 110 also electrically connected to an electrical device 200 mounted within a predetermined specified space.

The first and second body movement sensors 410 and 420 of the sensor 400 are preferably infrared sensors, but it should be clear that the first and second body movement sensors 410 and 420 may be a sensor selected from the group consisting of an ultrasonic sensor, a proximity sensor, and an optical sensor, having an output for transmitting light and an input for receiving light, which can detect the input and output of a person. In particular, an optical sensor having an output for transmitting light and an input for receiving light can control the detection distance and sensitivity by controlling the resistance value and can minimize the detection error of a user in the toilet, as he can correctly perform the operation to increase or decrease result by 1, according to the result found in the order of passage of light, reflection and reception of light. Additionally, the optical sensor has another advantage in that it minimizes a malfunction or error due to interference or overlapping detection between the sensors due to the directivity of the light.

The first body movement sensor 410 is installed at the entrance of a certain predetermined space or within a certain predetermined space adjacent to the entrance of a certain predetermined area, and the second body movement sensor 420 is installed on one adjacent section of a certain predetermined space, the inner surface of the ceiling, the wall surface, on a predetermined the distance from the first sensor moving the body in the internal direction of a given predetermined space. The second body movement sensor 420 is set to a position that does not overlap with the effective detection range of the first body movement sensor 410, namely, a position adjacent to the electrical device 200. An optical sensor having an output for transmitting light and an input for receiving light provides low interference between the sensors, and therefore, the first and second body movement sensors 410 and 420 can be mounted side by side. In this case, the sensors can be arranged in a row on the side surface at the entrance.

However, in the energy-saving switch according to the present invention, in addition to the optical sensor having an output for transmitting light and an input for receiving light, another sensor can be used. In this case, in order to prevent an error due to interference between the sensors, since the detection distance of the sensor is large, the first body movement sensor 410 is set so that the detection angle of the first body movement sensor 410 is set at an angle of about 5 ° with respect to the door frame to detect only a moving body entering and leaving a certain predetermined space, and a second body displacement sensor 420 is installed inside a certain predetermined space within a range so that the angle of aruzheniya second moving body sensor 420 does not overlap with the angle of the first moving body sensor 410. The detection angle can be adjusted by the manufacturer taking into account the area and structure of a specific predetermined space, but it is usually set at about 90 ° so that the innermost region of a certain predetermined space is an effective detection interval. Preferably, the detection angle of the second body movement sensor 420 is set without overlapping with the detection angle of the first body movement sensor 410 to minimize the occurrence rate of errors in detecting a moving body and maximize detection efficiency.

A detailed description of the position of the sensors will be omitted, and specialists in the art can install the sensors in the proper positions in accordance with the characteristics of the given space and the features of the sensors for moving the body.

The control means 110 comprises a circuit board integrated inside a junction box (not shown) comprising a manual switch 500, a first body motion sensor 410 or a second body motion sensor 420, and designed based on a micom circuit on the board. 14 and 15, the operation of the energy-saving switch will be described in more detail with a focus on the control means 110.

In Fig. 14, a first body displacement sensor installed at the input of a certain predetermined space or within a certain predetermined space adjacent to the entrance, and a second body displacement sensor installed inwardly with respect to the first body displacement sensor, detect the moving body in the order when the user enters to a specific predetermined space (S210, S220). At this time, when the control means 110 receives detection signals from the first and second body movement sensors 410 and 420 in the order of steps S210 and S220, the control means 110 automatically turns on the electric device 200 installed inside the determined predetermined space (S230). When the sensors detect that the user is entering a specific predetermined space, the electrical device 200 is turned on automatically.

When the user leaves a specific predetermined space, the second body motion sensor 420 installed inside the specific predetermined space detects this (S240), and then the first body motion sensor 410 detects a moving body. When the control means 110 receives the detection signals from the body movement sensors 410 and 420, the control means 110 recognizes that the user leaves a certain predetermined space and automatically turns off the electric device 200 (S250), and then returns to the initial step (S210) for continuous automatic switching on on and off.

After the power-saving switch automatically turns on or off, if the pre-set time period of the sensors is not stopped, since the body movement sensors are operated continuously, the electrical device may not work properly, for example, unnecessarily turn on or off due to the user's movement in the area adjacent to the sensors body movement. Therefore, the control device 110 of the energy-saving circuit breaker according to the invention automatically turns on the electrical device installed inside the defined predetermined space (S230) when it receives the detection signal from the second body movement sensor 420 after receiving the detection signal from the first body movement sensor 410. After that, the control means 110 turns off the first and second body movement sensors for a predetermined period of time (S231). Thereafter, it is preferable that the control means 110 automatically turn off the electrical device installed within the defined predetermined space (S260) upon receiving the detection signal from the first body movement sensor 410 after receiving the detection signal from the second body movement sensor 420 and then stopped the operation of the first and second sensors 410 and 420 moving the body for a predetermined period of time (S261).

In fact, the first and second body movement sensors 410 and 420 continuously detect a moving body, and therefore, the control means 110 automatically turns off the electric device 200 only when the steps of detecting a moving body by the first body movement / detecting body moving second body motion sensor -> operation and the steps of detecting a moving body with a second body moving sensor / detecting a moving body with a first body moving sensor -> stop is performed in It seemed right. As a result, the control means 110 can automatically turn on and off more securely by recognizing the movement of the user, as a model of the location shift input in / find inside / out of for a given predetermined space.

Embodiment 9

The energy-saving switch according to the present invention described above is effective in a small predetermined space, in the case where there is only one user in a certain predetermined space, but has the problem that the operation of the electrical device stops when a user leaves a large number of users, located in a certain given space, such as a public toilet for use by many people. Therefore, the energy-saving switch must have a unit for stopping the electrical device only when there are no people inside a certain predetermined space. According to FIG. 15, an energy saving switch comprising such a unit will be described.

The energy-saving circuit breaker according to the present invention automatically stops the operation of the electrical device 200 if it is determined that there are no users inside after detecting the number of users inside a certain predetermined space by a certain number of detections by the body displacement sensor. To detect the number of users within a certain predetermined space, the energy-saving switch control means 110 according to the present invention is activated when the user approaches a certain predetermined space (S301), namely, when the detection signals are detected in the following order: the first body movement sensor and the second body movement sensor (S302), and at this time performs the operation so as to increase the result by 1. In addition, the control means 110 performs an operation so as to reduce the result by 1 each time the user leaves a certain predetermined space, namely, each time when detection signals are detected in the following order: a second body movement sensor and a first body movement sensor (S304, S305).

The control means 110 continuously turns on the electric device 200 (S306) when the result of the operation exceeds 1 (when at least one user is inside a certain predetermined space), but stops the operation of the electric device 200 (S307) only when the result of the operation is 0 (when inside there is no user defined space). Preferably, the control tool recognizes the result of the operation that is less than 0, as 0, since the result of the operation that is less than 0 means a detection error.

The control method for automatically turning on and off according to the number of sensor detections has the advantage that the operation of the electrical device is stopped only when there are no users inside a certain predetermined space, even if several users randomly enter and exit a certain predetermined space, such like a public toilet.

In addition, as described above, the control means 110 may be electrically connected to a manual switch 500 mounted on the outer surface of the inlet of a predetermined predetermined space so that the control means 110 can manually turn on and off the electric device 200 in accordance with the intention of the user.

The energy-saving circuit breaker according to the present invention can be modified in various ways. That is, it should be noted that the energy-saving switch can be implemented so that the junction box of the manual switch 500 contains an indicator to inform the user from the outside that the other user is inside a certain predetermined space, which is also included in the technical context of the present invention.

Industrial applicability

As described above, compared with a conventional human body detection lighting system, the energy-saving circuit breaker according to the invention has lower manufacturing costs since it is designed simply to detect a moving body.

In addition, the present invention may include an electrical device by manually turning on the light and at the same time stopping the operation of the sensor for a predetermined period of time for the sensor to fail when detecting the user's proximity. When the user leaves a predetermined area, the sensor detects a moving body or opening or closing a door to automatically turn off the electrical device or output a specific sound to allow the user to recognize the “on” state of the electrical device. The present invention using a minimum of elements can provide an effect identical to that of several highly sensitive sensors.

Therefore, the present invention reduces cost, improves usability, improves energy efficiency and significantly increases the life of the electrical device.

In addition, the present invention displays “on” or “off” status information of an electrical device, lighting or displaying certain symbols or numbers, or turning on or off indicator lights or elements indicating symbols of a predetermined color, thereby controlling energy efficiently and increasing usability.

Various types of sensors can be used as a sensor, such as a body movement sensor, a door opening sensor for detecting opening and closing of a door, etc., i.e. the invention allows to expand the selection range of the manufacturer.

In addition, the invention can have various applications, for example, the user selectively operates in automatic mode, semi-automatic mode and manual mode. Since the light sensor is omitted in the present invention, it can reduce the error rate due to the light sensor, lower cost and implement simple technology through a simple design and simple control method.

In addition, in the case where several users use a specific predetermined space, the energy-saving switch according to the invention maintains the “on” state of the electrical device, even if several users enter a certain predetermined space so that unnecessary on and off switching are repeatedly generated, and automatically turns off electrical device after turning on and off control in accordance with the input and output of the user and after detecting input / presence / output yes user, ie, provides a control method for automatically turning an electric device on and off in accordance with a user location offset model. Thus, a new energy-saving switch is proposed, different from the known ones.

In addition, the present invention can expand the choice of manufacturers and consumers, since various types of body motion sensors can be used, which minimizes the frequency of occurrence of errors, as it provides very high detection efficiency, and improves usability, since a manual switch is installed at the input of a specific spaces for turning on and off by the user of the electrical device in accordance with the intention of the user.

Although the present invention has been described with respect to certain illustrative embodiments, it should not be limited to these embodiments, but solely by the appended claims.
