Remote Controlled Power Switch

The current invention pertains to a remote controlled power switch and, in particular, to the one which users can undoubtedly cut off the transmission of electric power, connect electric power, or switch the toggle between On/Off states with radiation-based signal control (e.g. infrared remote control).

A power switch is the one internal or peripheral component used to activate/off electric equipment. Currently, a power switch will be incorporated with infrared technologies to become a remote controlled power switch.

However, for present remote controlled power switches, users can only switch states of power with a remote controller. In other words, users cannot undoubtedly cut off or activate electric power with present remote controlled power switches. Accordingly, it is inconvenient for users, and electric power may be senselessly wasted. For example, with traditional remote controlled power switches, sometimes users cannot ensure that whether power of electric equipment is basically turned off in a rush before going out. Therefore, it’s necessary to develop a remote controlled power switch that may absolutely cut off or turn on electric power.

Recently, some IT companies enthusiastically have integrated home networking and external networking to develop electronic and intelligent-life circumstances, reminiscent of home power management, home security, home care, remote maintenance of appliances, digital interactive TV, etc. With the expectations of having an electronic and intelligent life, it’s believed that users are in need of making sure whether electric power is undoubtedly cut off or turned on.

Accordingly, one objective of the invention is to provide a remote controlled power switch that users can undoubtedly turn on/off power or switch between the states of ON and OFF with radiation-based signals control (e.g. infrared remote control).

Besides, living in the circumstances of electronic and intelligent life, it’s believed that users are in need of remote controlled power switches that may provide assistance in power management, home security, etc.

Therefore, another objective of the invention is to supply a remote controlled power switch that may provide assistance in power management, home security, etc.

In one preferred embodiment based on this invention, a remote controlled power switch includes a line interface, a radiation-based receiver, a processor, and a power supply. The road interface is electrically connected in series to a power line. The road interface is capable of being controlled to cut off or provide transmission of a primary electric power transmitted over the facility line. The radiation-based receiver is used for receiving a primary radiation-based signal and converting the primary radiation-based signal into a primary operative code. The processor is electrically connected to the line interface and the radiation-based receiver, respectively. The processor therein stores a glance-up table that records plural second operative codes and plural commands. The plural commands include a cutting-off command, a connecting command, and a toggling command. Each of the commands is corresponding to one of many second operative codes. The processor receives the primary operative code from the radiation-based receiver and judges if the first operative code could match one of many second operative codes. If the judging result is YES, the processor controls the line interface in response to the command corresponding to the second operative code that matches the primary operative code. And, the power supply is used for supplying a second electric power to the remote controlled power switch.

The advantage and spirit of the invention may be understood by the next recitations together with the appended drawings.

The remote controlled power switch is used for remotely controlling transmission of electric power over the power line. Specifically, with the remote controlled power switch and radiation-based signals, users can undoubtedly cut off transmission of the electric power, connect electric power, or switch between the two states of ON and OFF. Several preferred embodiments, based on the invention, are described below to explain the characteristics, spirit, advantages and convenience of the invention.

Please confer with FIG. 1A, which illustrates the block diagram of a remote controlled power switch 1 in one preferred embodiment according to the invention. The remote controlled power switch 1 includes a line interface 12, a power supply 14, a processor 18, and a radiation-based receiver 22.

As shown in FIG. 1A, the road interface 12 is connected in series to 1 power line between two power lines for transmitting a primary electric power to a loading 2. The road interface 12 is capable of being controlled to cut off or provide transmission of the primary electric power through the power line. Please seek advice from FIG. 1B, which illustrates another block diagram of the remote controlled power switch 1. In FIG. 1B, the road interface 12 is a triac. Besides, the line interface 12 can be a relay (not shown in FIG. 1A and FIG. 1B).

It must be noted that the remote controlled power switch 1 could be a peripheral power switch connected to the loading (electric equipment) 2. And, the remote controlled power switch 1 can be a power switch integrated into the loading (electric equipment) 2. For example, the loading 2 could also be an extended line or similar electronic equipment.

The remote controlled power switch 1, further, includes at the least one button 15 electrically connected to the processor 18. In response to pressing the button 15, the processor 18 controls the line interface 12 to chop off transmission of the primary electric power, connect the primary electric power, or switch between the two states.

Also as shown in FIG. 1A, the radiation-based receiver 22 is used for receiving a primary radiation-based signal and converting the primary radiation-based signal into a primary operative code. The first radiation-based signal could also be transmitted from a remote controller (not shown in FIG. 1A).

In one embodiment, the primary radiation-based signal is an infrared signal and the radiation-based receiver 22 is an infrared receiver.

Also as shown in FIG. 1A, the processor 18 is electrically connected to the line interface 12 and the radiation-based receiver 22, respectively. The processor 18 stores a look-up table 182 that records plural second operative codes and plural commands. The plural commands include a cutting-off command, a connecting command, and a toggling command. Each of the commands is corresponding to one of the second operative codes. The processor 18 receives the first operative code from the radiation-based receiver 22 and judges if the primary operative code could match one of the second operative codes. If the judging result’s YES, the processor 18 controls the road interface 12 in keeping with the command corresponding to the second operative code that matches the first operative code.

Also as shown in FIG. 1A, the facility supply 14 is electrically connected to the line interface 12 and the processor 18, respectively. The power supply 14 supplies a second electric power for operation of the remote controlled power switch 1.

It ought to be noted that the cutting-off command is used to cut off transmission of the first electric power, such that a minimum of one loading (electric equipment) utilizing the first electric power is was an OFF state. The connecting command is used to supply transmission of the primary electric power, such that at the least one loading (electric equipment) utilizing the first electric power is was an ON state. The toggling command is used to chop off or provide transmission of the primary electric power, such that a minimum of one loading (electric equipment) utilizing the first electric power is switched between ON/OFF states. If electric equipment is in an OFF state, when the processor 18 within the remote controlled power switch 1 receives the toggling command, the electric equipment will be switched into an ON state. Similarly, if the processor 18 in the remote controlled power switch 1 receives the toggling command again, the electric equipment shall be switched into an OFF state from the ON state.

Based on the descriptions above, it may be clearly understood that, with the remote controlled power switch 1 based on this invention, users can undoubtedly and remotely cut off or provide transmission of the electric power.

Also as shown in FIG. 1A, in one embodiment, the power supply 14 can include a converter 141, a primary adapter 143, a second adapter 145, and a voltage regulator 147. The converter 141 is electrically connected to the power line and used for converting the first electric power into a 3rd electric power. The primary adapter 143 is electrically connected in parallel to the line interface 12 and used for receiving a fourth electric power from the line interface 12. The second adapter 145 is electrically connected to the converter 141 and used for receiving the third electric power from the converter 141. The voltage regulator 147 is electrically connected to the first adapter 143 and the second adapter 145, respectively. The voltage regulator 147 is used for regulating and converting the third or the fourth electric power into the second electric power. In another embodiment, the ability supply 14 generally is a battery.

In another embodiment, the aforementioned first adapter 143 and the second adapter 145 can be integrated into a double-adapter.

In addition to the commands, the remote controlled power switch 1 can even judge whether to cut off transmission of the first electric power based on a current of the first electric power, in order to make sure safety. On this embodiment, the converter 141 is also used to detect a loading current flowing through the road interface 12. As shown in FIG. 1A, the remote controlled power switch 1 further includes an A/D converter 16. The A/D converter 16 is electrically connected to the converter 141 and the processor 18, respectively. The A/D converter 16 converts the loading current detected by the converter 141 right into a current value and transmits the current value to the processor 18. The processor 18 then judges whether the current value is higher than a user-defined threshold or not. If the judging result is YES, the processor 18 will control the road interface to chop off transmission of the primary electric power.

In order for users to query the present value of the first electric power, in another embodiment, the remote controlled power switch 1 further includes a radiation-based transmitter 20, as shown in FIG. 1A and FIG. 1B. The radiation-based transmitter 20 is electrically connected to the processor 18. As well as, the plural commands include a current-replying command. In response to the current-replying command, the processor 18 receives the present value from the A/D converter 16 and interprets the present value into one of the second operative codes. Then, the processor 18 transmits a second radiation-based signal that represents the interpreted second operative code to a remote controller via the radiation-based transmitter 20.

Please consult with FIG. 2, which illustrates an example of the look-up table 182 stored within the processor 18.

For users to question the state of the remote controlled power switch 1, in another embodiment, the remote controlled power switch 1 may include the radiation-based transmitter 20 above. On this embodiment, the processor 18 also records a switching state. The switching state is relative to a transmission state of the primary electric power over the power line. The plural commands further include a state-replying command. In response to the state-replying command, the processor 18 interprets the switching state as one of many second operative codes. Subsequently, the processor 18 transmits a second radiation-based signal that represents the interpreted second operative code to the remote controller via the radiation-based transmitter 20.

In another embodiment, the remote controlled power switch 1 further includes the above mentioned radiation-based transmitter 20 and a clock 17 The clock 17 and the radiation-based transmitter 20 are respectively electrically connected to the processor 18. A user-defined period is stored within the processor 18. The processor 18 receives the current value from the A/D converter 16 and judges whether the present value is received in the user-defined period or not. If the judging result’s YES, the processor 18 will control the line interface 12 to chop off transmission of the first electric power and transmit, via the radiation-based transmitter, a 3rd radiation-based signal that’s an alerting signal.

Users can set, as an illustration, a period time of going-out or a period time of sleeping in the aforementioned user-defined period. Normally, the remote controlled power switch 1 is just not turned on during these periods. Namely, through the user-defined periods, if the remote controlled power switch 1 inside or peripherally connected to electric equipment is turned on, the processor 18 will receive the current value from the A/D converter 16 and control the road interface 12 to chop off power over the facility line. Thus, invaders cannot arbitrarily steal or destroy things within the house. At the identical time, the processor 18 will control the radiation-based transmitter 20 to transmit an alarm to the radiation-based receiver 22. Then, the alarm signal shall be used for triggering various alarm systems. And, the alarm signal will also be transmitted to users or police offices. In this way, the remote controlled power switch 1, in line with this invention, can provide home security.

In a single embodiment, the processor 18 controls the line interface 12 and limits a loading current flowing through the road interface 12 based on a predetermined current limit. In this way, the remote controlled power switch 1, in keeping with this invention, can provide power management.

In actual applications, the remote controlled power switch, in response to this invention, could be equipped with various operation or communication interfaces. Please refer back to FIG. 1B. The remote controlled power switch 1 in another embodiment based on this invention further includes a display 24 and a data communication interface 26.

The display 24 is electrically connected to the processor 18. The display is operated by the processor 18 and used for displaying the second operative codes and the commands.

The information communication interface 26 can also be electrically connected to the processor 18. The information communication interface 26 is configured to be connected to external electronic equipment; for instance, home gateway of the house networking. In this fashion, users can directly connect with their home network and control the remote controlled power switch 1 with no remote controller.
