Description

1 REMOTE CONTROLLED ELECTRICAL OUTLET Technical Field [0001] The present invention relates generally to electrical outlets that can be remotely controlled to connect and disconnect electrical power supply from an electrical load. Background [0002] Fig. 1 shows a conventional arrangement 100 of a remote controlled electrical outlet 101A that is capable of being turned on and off (i.e., to connect and disconnect electrical power supply from an electrical load, respectively) by a remote device 102. The outlet 101 and the device 102 are wirelessly connected via connection 104. The connection 104 is typically a short range wireless communication protocol, such as a proprietary wireless protocol or BluetoothTM A problem with the arrangement of 100 is the short range which limits the utility of the arrangement 100 for a user. Further, the arrangement 100 typically requires a dedicated remote control 102, which functions solely to control the outlet 101. [0003] The connection 104 may alternatively be provided by a local-area communications network. However, a problem with using the local-area communications network is that a user typically requires a certain degree of technical expertise to setup the connections between the local-area communications network and both the outlet 101 and the device 102. Thus, such a connection is typically limited to users with sufficient technical knowledge and depends on the availability of the local-area communications network 108. Summary [0004] It is an object of the present invention to substantially overcome, or at least ameliorate, one or more disadvantages of existing arrangements. [0005] According to an aspect of the present disclosure, there is provided an apparatus for providing electrical power to one or more electrical loads, the apparatus comprising: at least one electrical outlet; at least one switch for enabling an electrical supply to be connected to the one or more electrical loads via the electrical outlet; 2 a circuit for receiving a subscriber identity module (SIM), wherein the SIM is activated and pre-installed in the apparatus before the apparatus is offered for sale to users; a receiver connected to the circuit for receiving a data packet from a controller via a first network relating to the SIM, the data packet being received by the controller from a plurality of devices via a second network, the data packet including information identifying the apparatus from a plurality of apparatuses to enable the controller to identify the apparatus and a command to actuate the at least one switch to either connect the electrical power supply to the one or more electrical loads via the electrical outlet or disconnect the electrical power supply from the one or more electrical loads, and a processor connected to the receiver and the at least one switch for actuating the at least one switch based on the received data packet.

Brief Description of the Drawings [0007] Some aspects of the prior art and at least one embodiment of the present invention will now be described with reference to the drawings, in which: [0008] Fig. 1 shows a prior art arrangement for a conventional remote controlled outlet; [0009] Fig. 2 is a block diagram of a remote controlled outlet system; [0010] Figs. 3A and 3B collectively form a schematic block diagram representation of the remote controlled outlet of Fig. 2; [0011] Figs. 4A to 4C are flowcharts for operating the components of the system of Fig. 2 to remotely control the outlet of Figs. 2, 3A and 3B. Detailed Description including Best Mode [0012] Where reference is made in any one or more of the accompanying drawings to steps and/or features, which have the same reference numerals, those steps and/or features have for the purposes of this description the same function(s) or operation(s), unless the contrary intention appears. [0013] It is to be noted that the discussions contained in the "Background" section and that above relating to prior art arrangements relate to discussions of documents or devices which form public knowledge through their respective publication and/or use. Such should not be 4 interpreted as a representation by the present inventor(s) or the patent applicant that such documents or devices in any way form part of the common general knowledge in the art. [0014] Fig. 2 shows a block diagram of a system 200 for use in the remote control of an electrical outlet. The system 200 includes a plurality of electrical outlets 202A to 202N, devices 204A to 204N, a data centre 212, a wide-area communications network 106, and a mobile communications network 110. [0015] Each of the electrical outlets 202A to 202N will be generically referred to as the outlet 202 hereinafter and the electrical outlets 202A to 202N will be collectively referred to as the outlets 202. As shown in Fig. 2, each outlet 202 is connected to an electrical supply 220 and an electrical load 222. Although only one electrical supply 220 and one electrical load 222 are shown in Fig. 2, more than one electrical supply 220 and more than one electrical load 222 may be connected to each outlet 202. One or more of the outlets 202 may be arranged in an apparatus, such as an electrical power board. The outlet 202 is described in detail below. [0016] Each of the devices 204A to 204N will be generically referred to as the device 204 hereinafter and the devices 204A to 204N will be collectively referred to as the devices 204. Each of the devices 204 may be any one of a smartphone, a tablet, a laptop, a desktop computer, or the like. In the example of Fig. 2, each of the devices 204 comprises a processor connected to a memory, such as the processor 205A and memory 206A of the device 204A. Again, the processors 205A to 205N will be generically referred to as the processor 205 hereinafter and the processors 205A to 205N will be hereinafter collectively referred to as the processors 205. Similarly, the memory 206A-206N will be generically referred to as the memory 206 hereinafter and the memories 206A to 206N will be hereinafter collectively referred to as the memories 206. [0017] Each of the devices 204 comprise an application program resident in the memory 206 and being controlled in its execution by the processor 205 to enable the device 204 to communicate with the data centre 212 (using the wide-area communications network 106) to send commands to or receive data from the outlets 202. The application program may be downloaded from a website provided by the manufacturer of the outlets 202. Alternatively, the application program may be an app available through an app store, which is managed by suppliers such as AppleTM, GoogleTM, Microsoft T M , etc.. [0018] To send commands to an outlet 202, the application program executed by the device 204 enables the user to select an outlet 202 to which commands are to be sent. The 5 application program also enables the user to select a command such as connect, disconnect, and status request of outlet 202. Once the user has selected the outlet 202 and the command, the application program executed by the device 204 encapsulates both the command and the address of the selected outlet 202 in a data packet and sends the data packet to the data centre 212. [0019] Upon receipt of the data packet from the device 204, the data centre 212 determines an address of the selected outlet 202 from the address encapsulated in the received data packet and forwards the data packet to the selected outlet 202. [0020] When the outlet 202 receives the data packet, the outlet 202 determines the command encapsulated in the data packet. If the command received is to either "connect" or "disconnect" the electrical power supply, the outlet 202 performs the command accordingly. If the command selected on the device 204 is to request the status of the selected outlet 202, then the outlet 202 sends a data packet (which encapsulates the status of the outlet 202 and the address of the device 204 that requested the status of the outlet 202) to the data centre 212, which then forwards the data received from the outlet 202 to the device 204. [0021] Any suitable addressing method may be used to enable data packets sent by the devices 204 to be forwarded by the data centre 212 to the selected outlet 202 and, similarly, data packets sent by the outlet 202 to be forwarded by the data centre 212 to the intended recipient device 204. [0022] The wide-area communications network 106 may be the Internet, a mobile communications network, or a private wide area network. The connections 206 and 210 may be wired or wireless. [0023] The mobile communications network 110 is also known as the cellular communications network, which is managed by a cellular service provider. The connection 216 between the mobile communications network 110 and the outlets 202 is a wireless radio frequency connection. The connection 211 between the data centre 212 and the mobile communications network 110 is typically a VPN operating over the internet or a fixed fibre optic connection.. [0024] The operation of the system 200 will be further described when discussing the methods shown in Figs. 4A to 4C.

6 Outlet Description [0025] Figs. 3A and 3B collectively form a schematic block diagram of the outlet 202 including embedded components, upon which the method described in Fig. 4C is desirably practiced. [0026] As seen in Fig. 3A, the outlet 202 comprises an embedded controller 302. In the present example, the controller 302 has a processing unit (or processor) 305 which is bi directionally coupled to an internal storage module 309. The storage module 309 may be formed from non-volatile semiconductor read only memory (ROM) 360 and semiconductor random access memory (RAM) 370, as seen in Fig. 3B. The RAM 370 may be volatile, non volatile or a combination of volatile and non-volatile memory. [0027] The outlet 202 may include a display controller 307, which is connected to a video display 314, such as a liquid crystal display (LCD) panel or the like. The display controller 307 is configured for displaying graphical images on the video display 314 in accordance with instructions received from the embedded controller 302, to which the display controller 307 is connected. For example, the outlet 202 may display the status (i.e., on or off) of the outlet 202 on the display 314. [0028] The outlet 202 also includes a switch 313, coupled to the controller 302, to enable a connection between the electrical power supply 220 to the electrical load 222. The switch 313 is actuated in accordance with instructions received from the embedded controller 302. For example, the switch 313 is actuated to a first position to connect the electrical power supply 220 to the electrical load 222, and the switch 313 is actuated to a second position to disconnect the electrical power supply 220 from the electrical load 222. [0029] As seen in Fig. 3A, the outlet 202 also comprises a portable memory interface 306, which is coupled to the processor 305 via a connection 319. The portable memory interface 306 allows a complementary portable memory device 325 to be coupled to the outlet 202 to act as a source or destination of data or to supplement the internal storage module 309. Examples of such interfaces permit coupling with portable memory devices such as Universal Serial Bus (USB) memory devices, Secure Digital (SD) cards, Personal Computer Memory Card International Association (PCMIA) cards, optical disks and magnetic disks. [0030] The outlet 202 also has a communications interface 308 to permit coupling of the outlet 202 to the mobile communications network 110 via a connection 216. The communications interface 308 includes a receiver for receiving data from the mobile 7 communications network 110 and a transmitter for transmitting data to the mobile communications network 110. The connection 216 is wireless radio frequency. The switch 313 is actuated based on data received by the controller 302 from the mobile communications network 110. [0031] The outlet 202 also has circuit 309 to receive a Subscriber Identity Module (SIM) 311 that is configured to enable communications with the mobile communications network 110. The circuit 309 is connected to the receiver and transmitter in the communications interface 308 to enable communications between the outlet 202 and the data centre 212 via the mobile communications network 110. The SIM 311 is activated and pre-installed in the outlet 202 before the outlet 202 is offered for sale to users, as arranged by the manufacturer. Thus, when a user buys the outlet 202, the user only needs to install the application program onto the user's device 204 and enter the address (e.g., an identification number) of the outlet 202 into the application program to enable control of the purchased outlet 202 from the device 204. [0032] The outlet 202 may be configured to prevent users from accessing the SIM 311, thereby precluding the users from changing the pre-installed SIM 311. For example, access to the SIM 311 can be restricted by using tamper-resistant screws. [0033] The methods described hereinafter may be implemented using the embedded controller 302, where the process of Fig. 4C may be implemented as one or more software application programs 333 executable within the embedded controller 302. With reference to Fig. 3B, the steps of the described method are effected by instructions in the software 333 that are carried out within the controller 302. The software instructions may be formed as one or more code modules, each for performing one or more particular tasks. The software may also be divided into two separate parts, in which a first part and the corresponding code modules performs the described methods and a second part and the corresponding code modules manage a user interface between the first part and the user. [0034] The software 333 of the embedded controller 302 is typically stored in the non-volatile ROM 360 of the internal storage module 309. The software 333 stored in the ROM 360 can be updated when required from a computer readable medium. The software 333 can be loaded into and executed by the processor 305. In some instances, the processor 305 may execute software instructions that are located in RAM 370. Software instructions may be loaded into the RAM 370 by the processor 305 initiating a copy of one or more code modules from ROM 360 into RAM 370. Alternatively, the software instructions of one or more code modules may be pre installed in a non-volatile region of RAM 370 by a manufacturer. After one or more code 8 modules have been located in RAM 370, the processor 305 may execute software instructions of the one or more code modules. [0035] The application program 333 is typically pre-installed and stored in the ROM 360 by a manufacturer, prior to distribution of the electronic device 202. However, the manufacturer may choose to supply the application programs 333 to the user encoded on one or more portable memory devices (not shown), which is read via the portable memory interface 306 of Fig. 3A prior to storage in the internal storage module 309 or in the portable memory 325. In another alternative, the software application program 333 may be read by the processor 305 from the network 110. [0036] The second part of the application programs 333 and the corresponding code modules mentioned above may be executed to implement one or more graphical user interfaces (GUls) to be rendered or otherwise represented upon the display 314 of Fig. 3A. [0037] Fig. 3B illustrates in detail the embedded controller 302 having the processor 305 for executing the application programs 333 and the internal storage 309. The internal storage 309 comprises read only memory (ROM) 360 and random access memory (RAM) 370. The processor 305 is able to execute the application programs 333 stored in one or both of the connected memories 360 and 370. When the outlet 202 is initially powered up, a system program resident in the ROM 360 is executed. The application program 333 permanently stored in the ROM 360 is sometimes referred to as "firmware". Execution of the firmware by the processor 305 may fulfil various functions, including processor management, memory management, device management, storage management and user interface. [0038] The processor 305 typically includes a number of functional modules including a control unit (CU) 351, an arithmetic logic unit (ALU) 352, a digital signal processor (DSP) 353 and a local or internal memory comprising a set of registers 354 which typically contain atomic data elements 356, 357, along with internal buffer or cache memory 355. One or more internal buses 359 interconnect these functional modules. The processor 305 typically also has one or more interfaces 358 for communicating with external devices via system bus 381, using a connection 361. [0039] The application program 333 includes a sequence of instructions 362 though 363 that may include conditional branch and loop instructions. The program 333 may also include data, which is used in execution of the program 333. This data may be stored as part of the instruction or in a separate location 364 within the ROM 360 or RAM 370.

9 [0040] In general, the processor 305 is given a set of instructions, which are executed therein. This set of instructions may be organised into blocks, which perform specific tasks or handle specific events that occur in the outlet 202. Typically, the application program 333 waits for events and subsequently executes the block of code associated with that event. Events may be triggered in response to input from a user, received via the mobile communications network 110, as detected by the processor 305. [0041] The execution of a set of the instructions may require numeric variables to be read and modified. Such numeric variables are stored in the RAM 370. The disclosed method uses input variables 371 that are stored in known locations 372, 373 in the memory 370. The input variables 371 are processed to produce output variables 377 that are stored in known locations 378, 379 in the memory 370. Intermediate variables 374 may be stored in additional memory locations in locations 375, 376 of the memory 370. Alternatively, some intermediate variables may only exist in the registers 354 of the processor 305. [0042] The execution of a sequence of instructions is achieved in the processor 305 by repeated application of a fetch-execute cycle. The control unit 351 of the processor 305 maintains a register called the program counter, which contains the address in ROM 360 or RAM 370 of the next instruction to be executed. At the start of the fetch execute cycle, the contents of the memory address indexed by the program counter is loaded into the control unit 351. The instruction thus loaded controls the subsequent operation of the processor 305, causing for example, data to be loaded from ROM memory 360 into processor registers 354, the contents of a register to be arithmetically combined with the contents of another register, the contents of a register to be written to the location stored in another register and so on. At the end of the fetch execute cycle the program counter is updated to point to the next instruction in the system program code. Depending on the instruction just executed this may involve incrementing the address contained in the program counter or loading the program counter with a new address in order to achieve a branch operation. [0043] Each step or sub-process in the processes of the methods described below is associated with one or more segments of the application program 333, and is performed by repeated execution of a fetch-execute cycle in the processor 305 or similar programmatic operation of other independent processor blocks in the outlet 202. [0044] Fig. 4A shows a method 400A for operating the device 204 to remotely control the outlet 202. Fig. 4B shows a method 400B for operating the data centre 212 to forward data packets received from the outlet 202 and the device 204 to the device 204 and the outlet 202, 10 respectively. Fig. 4C shows a method 400C for operating the outlet 202 upon receipt of data packets from the device 204. [0045] Referring to Fig. 4A, steps 402, 404 and 406 of the method 400A may be implemented by the application program resident in the memory 206 and being controlled in its execution by the processor 205 of the device 204 in order to remotely control the outlet 202. The method 400A starts with step 402 where a user of the device 204 is presented with a selection of the outlets 202, to which the user has control. For example, a list of the selectable outlets 202 may be displayed on a display of the device 204. In one arrangement, the display may be a touch screen. The user then selects one of the presented outlets 202 (e.g., via a hand gesture on the display of the device 204), which the user wants to remotely control. The application program in the device 204 then receives a selection of the outlet 202 and the method 400A proceeds to step 404. [0046] In step 404, the application program of the device 204, under execution of the processor 205, presents a list of commands available to be sent to the selected outlet 202. These commands may be any one of the following: connect power supply to an electrical load, disconnect power supply from the electrical load, and status request of the outlet 202. The application program 204, under execution of the processor 205, then receives a selection of the commands for the selected outlet 202 from the user and the method 400A proceeds to step 406. [0047] In step 406, the application program, under execution of the processor 205, prepares a data packet to be sent by encapsulating the received selection of the outlet 202, the selected command, and the address of the device 204 into the data packet. The data packet is then transmitted to the data centre 212 via the wide-area communications network 106. The method 400A concludes. [0048] Referring to Fig. 4B, the method 400B is the operation of the data centre 212 to forward received data to either the outlets 202 or the devices 204. In one arrangement shown in Fig. 2, the data centre 212 may be implemented by a server computer including a processor 235 connected to a memory 236. The method 400B may be implemented by a software application program resident in the memory 236 and being controlled in its execution by the processor 235. The method 400B commences with step 408 where the data packet is received by the data centre, under execution of the processor 235, from either the devices 204 via the wide-area communications network 106 via connections 206 and 210; or the outlets 202 from 11 the mobile communications network 110 via connections 210 and 216. The method 400B then proceeds to step 410. [0049] In step 410, the data centre 212 determines, under execution of the processor 235, an outlet 202 or a device 204 to which the data packet (received in step 408) is to be sent. The data centre 212 reads the received data packet and, based on the addressing method used, determines the address of the outlet 202 or the device 204 as encapsulated in the received data packet. For example, if the received data packet is from the device 204, then the data centre 212 determines the selected outlet 202 as the address of the selected outlet 202 is encapsulated in the data packet (see step 406). An example of determining the address of the device 204 when the data packet is received from the outlet 202 is described below in relation to method 400C. The method 400B then proceeds to step 412. [0050] In step 412, the data centre 212, under execution of the processor 235, transmits the data packet to the outlet 202 using the mobile communications network 110 via connections 210 and 216; or the device 204 via the wide-area communications network 106 via connections 206 and 210, as determined in step 410. The method 400B concludes. [0051] Referring to Fig. 4C, the method 400C is the operation of the outlet 202 upon receiving data packets from the device 204. The method 400C may be implemented as one or more code modules of the software application programs 333 resident in the internal storage module 309 and being controlled in its execution by the processor 305. [0052] The method 400C commences at step 416 when the outlet 202 receives the data packet from the data centre 212 via the mobile communications network 110 using connection 216. The data packet, in particular, is received by the processor 305 via the communications interface 308 in the outlet 202. The method 400C proceeds to step 418. [0053] In step 418, the outlet 202 determines the command encapsulated in the received data packet. In particular, the processor 305 executes the application program 333 to determine the command encapsulated in the received data packet. If the command is determined to be for turning on or off the outlet 202, then the method 400C proceeds to step 420. If the command is determined to be a status update of the outlet 202, then the method 400C proceeds to step 422. [0054] In step 420, the outlet 202 actuates the switch 313, under execution of the processor 305, based on the determined command. In particular, the processor 305 sends a signal (based on the determined command) to the switch 313 to either connect the electrical supply 12 220 to the electrical load 222; or disconnect the electrical supply 220 from the electrical load 222. The method 400C then concludes. [0055] In step 422, the outlet 202 prepares the data packet to be sent by encapsulating the status of the outlet 202 and the intended recipient device 204 into the data. The address of the recipient device 204 is determined from the data packet received at step 416 (also see step 406, where the address of the device 204 is encapsulated in the data packet). The prepared data packet is then transmitted to the data centre 212 via the mobile communications network 110. The method 400C concludes. [0056] When the data centre 212 receives the data from the outlet 202, the method 400B (as described above) is executed by the data centre 212 so that the data packet is forwarded to the device 204. The steps of the method 400B are as described above. For step 410, the data centre 212 determines the recipient device 204 from the address of the device 204 as encapsulated in the data packet (see step 422). Industrial Applicability [0057] The arrangements described are applicable to the power industries and particularly for the remote control of power outlets. [0058] The foregoing describes only some embodiments of the present invention, and modifications and/or changes can be made thereto without departing from the scope and spirit of the invention, the embodiments being illustrative and not restrictive. [0059] In the context of this specification, the word "comprising" means "including principally but not necessarily solely" or "having" or "including", and not "consisting only of'. Variations of the word "comprising", such as "comprise" and "comprises" have correspondingly varied meanings.
