Description

  The present invention relates to a wall-embedded switch device that supplies and cuts off power from a power line to a load, and a switch control program that controls the operation of the switch device.

  Generally, a switch is used to supply and cut off power to a load. For example, in order to turn on / off a room lighting or the like, a switch attached to be embedded in a wall surface of the room is used. Such a switch generally has a structure in which a switch module having various functions is attached to an embedded switch box. In general, mechanical switches and electronic switches are widely used as such switches.

  The mechanical switch has a simple structure in which a switch module that turns on and off a mechanical contact by operating an operation button can be attached to a standardized switch box such as one or two of JIS. Widely popular. In recent years, switches having various functions are commercially available as mechanical switches. For example, there are a switch having a delay operation function for performing an OFF operation after a certain time has elapsed from the OFF operation, and a switch having a timer function.

  On the other hand, the electronic switch employs relay control that turns the relay ON / OFF by operating the operation button. For this reason, the electronic switch can arrange a large number of small operation buttons on the switch operation surface, and is suitable for turning on / off the illumination of each section in a wide space such as an office. Further, as described in Patent Document 1, the electronic switch can remotely control an ON / OFF target by relay control (full two-wire remote controller).

JP 2005-101941 A (published on April 14, 2005) Special table 2008-533753 gazette (announced on August 21, 2008)

  Mechanical switches are usually designed to have a specific function. For this reason, when using a new function, it is necessary to remove the switch module attached to the switch box and replace it with a switch module having a desired new function. Thus, with a mechanical switch, a new function cannot be added after installation.

  In addition, in the remote control system using an electronic switch, if an attempt is made to repair the existing state, construction work and adjustment work are required. For this reason, it is necessary for a specialized trader to cope with the repair, and there is a disadvantage that the cost increases.

  In addition, since the mechanical switch and the electronic switch are both hardware switches, if the switch design is to be changed, the mechanism itself needs to be replaced. For example, when changing the design of the switch operating section or the cover, these are replaced as parts. For this reason, replacement work is required, and switch manufacturers and sellers must provide replacement parts.

  Incidentally, the function expandability is described in Patent Document 2. Patent Document 2 describes a configuration in which a functional unit having various functions can be easily added by a user for an outlet, although it is not a switch. Specifically, this configuration has a structure in which an additional function unit can be connected to a basic function unit (outlet), and another additional function unit can be connected to the additional function unit. As a result, a plurality of additional function units can be connected to the function unit in succession. Therefore, when such a configuration is applied to the switch, a new function can be added to the switch by simply connecting an additional function unit to the function unit or the additional function unit connected to the function unit.

  However, when such a configuration is applied to a switch, it is necessary to connect additional function units according to the function to be added. For this reason, as the number of functions increases, the number of additional function units increases, and there is a limit to the addition of functions.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to facilitate design change and function addition in a wall-embedded switch without requiring hardware change. It is to provide a switching device that can.

  The switch device according to the present invention switches the supply and cut-off of power to a load via a power line, and is a switch device mounted in a switch box embedded in a wall. A display panel for displaying a switch image, a touch panel for detecting a position of a touch operation on the display panel, a relay circuit for switching connection and disconnection of the power line, and a relay circuit according to a touch operation on the touch panel. Relay control means for controlling operation, wireless communication means for wirelessly communicating with an external communication device, and image data of the switch image and a program for realizing a function to be added to the switch device are acquired from the external communication device by the wireless communication. Acquisition means for storing the acquired image data and the program. It is characterized in that it comprises a memory for.

  In the above configuration, the user touches the touch panel on the switch image displayed on the display panel. When power is supplied to the load, when the touch panel is touched, the relay control unit operates the relay circuit to connect the power line (ON operation). As a result, the relay circuit becomes conductive and power is supplied from the power line to the load.

  In the switch device, when the power supply to the load is stopped, when the touch operation is performed in the same manner as described above, the relay control unit operates the relay circuit to connect the power line (OFF operation). Thereby, the said relay circuit interrupts | blocks and the electric power supply to a load from a power line is stopped.

  The switch device wirelessly communicates with the external communication device by the wireless communication unit, whereby the image data and the program are acquired from the external communication device by the acquisition unit. The image data and program are stored in the memory. Thereby, the design of the switch device can be easily changed by displaying the acquired image data on the display panel. Further, by using the acquired program, a function realized by the program can be added to the switch device. In addition, if the external communication device is another switching device, wireless communication can be performed between the switching devices. Thereby, an interphone call can be realized between the switch devices by adding a call function (a microphone and a speaker) to the switch devices.

  The switch device is attached to a wall-embedded switch box. Thereby, for example, it can be easily replaced with an existing switch unit attached to a standardized switch box widely used in ordinary houses. Therefore, the switch device can be easily introduced.

  The switch device preferably includes a mail transmission unit that transmits a mail to the external communication device by the wireless communication in response to a touch operation on the touch panel for connecting the relay circuit.

  In the above configuration, the mail is transmitted by the mail transmission means to the other party of the transmission destination with the touch operation. Therefore, the mail receiving side can confirm that a person is present in the room in which the touch-operated switch device is installed. For example, if the load is a lighting fixture, it can be confirmed on the mail receiving side that a touch operation for turning on the lighting fixture has been performed. As a result, it is possible to confirm safety and confirm the intrusion of a suspicious person even in a remote place.

  The switch device includes voice reproducing means for reproducing voice data, and mail receiving means for receiving a mail attached with the voice data by the wireless communication from the external communication device, and the mail receiving means includes the relay It is preferable that when the touch operation on the touch panel for connecting a circuit is performed, the audio reproduction unit reproduces the audio data.

  In the above configuration, the mail receiving unit receives the mail with the voice data attached. Further, when a touch operation is performed on the switch device, the audio data is reproduced by the audio reproducing means in accordance with the touch operation. Thereby, for example, if the load is a lighting fixture, a sound can be heard when the lighting fixture is turned on at home or the like by performing a touch operation for lighting the lighting fixture. Therefore, it is possible to convey a message or a birthday celebration as a message.

  The switch device includes a date and time management unit that manages the date and time for controlling the operation of the relay circuit, and instructs the relay control unit to control the relay circuit at the date and time, and the relay control unit includes the date and time management unit. It is preferable to control the operation of the relay circuit based on an instruction from the means.

  In the above configuration, the date management unit instructs the relay control unit to control the relay circuit at the managed date. In response to this instruction, the relay control means controls the operation of the relay circuit. Thereby, the load can be operated during a desired period. In particular, if the load is a luminaire, lighting the luminaire for a desired period is effective as a nighttime security measure in the absence home.

  The switch device preferably includes timer means for measuring a preset set time, and the relay control means controls the operation of the relay circuit when the set time is counted by the timer means.

  In the above configuration, when the set time is counted by the timer means, the relay control means is instructed to control the relay circuit. In response to this instruction, the relay control means controls the operation of the relay circuit. As a result, the timer function, the delayed turn-off function, and the forget-off function that the conventional switches individually have can be incorporated into one switch device. In particular, if the load is a lighting fixture, the alarm function can be realized by turning on the lighting fixture after a set time. Moreover, when using as an alarm function, it is more preferable to combine a lighting fixture and audio output.

  The switch device is an infrared communication unit in which the wireless communication unit performs infrared communication with a portable terminal device as the external communication device, and the relay control unit receives an operation instruction received from the portable terminal device by the infrared communication unit. Accordingly, it is preferable to control the operation of the relay circuit.

  Thus, when an operation instruction is received from a portable terminal device such as a mobile phone using infrared communication by the infrared communication means, the operation of the relay circuit is controlled by the relay control means in accordance with the operation instruction. Thereby, the mobile terminal device can be used as a remote controller for operating the load.

  The switch device includes an energization time measurement unit that measures an energization time of the load, a load capacity acquisition unit that acquires a load capacity of the load, and an electric power integration by multiplying the measured energization time and the load capacity. It is preferable that an integrated value calculation unit that calculates a value and a display control unit that displays the integrated power value on the display panel.

  Thereby, the integrated value calculation means calculates the integrated power value based on the energization time measured by the energization time measurement means and the load capacity acquired by the load capacity acquisition means. Thereby, it is possible to confirm the rough power consumption and amount of the load. Therefore, it is possible to give the user a motivation to raise power saving awareness. As a result, it is possible to easily tackle effective use of a load conscious of energy saving.

  The switch device includes an electromagnetic relay in which the relay circuit switches connection and disconnection of the power line, and a semiconductor relay that excites a coil of the relay, and the relay control unit controls the operation of the semiconductor relay. It is preferable to control the operation of the relay circuit.

  Thus, the relay circuit can reduce the current supplied to the exciting coil of the electromagnetic relay by combining the electromagnetic relay and the semiconductor relay. Usually, in order to drive the contact of the relay circuit in order to connect and disconnect the power line supplying 100 V (3 A), it is necessary to supply a large current to the exciting coil. For this reason, since a dedicated power source is required for supplying current to the exciting coil, if such a relay is employed as a relay circuit, it is difficult to reduce the size of the switch device. Therefore, by using a semiconductor relay like the above-described relay circuit, the contact can be driven by supplying a small current from the power line to the exciting coil, so that it is not necessary to use another power source. Therefore, the switch device can be reduced in size.

  The switch control program of the present invention is a program for causing a computer to function as the relay control means and the acquisition means in a switch device. In this way, the switch device can be controlled by software by causing the computer to read and execute the switch control indication program. Thereby, the control of the relay circuit can be easily combined with other functions. Examples of such a function include a function for performing various operations related to a touch operation.

  Since the switch device according to the present invention is configured as described above, there is an effect that it is possible to easily change the design and add functions without requiring hardware changes.

  Here, this embodiment demonstrates the example which uses the lighting fixture 49 as a load. However, the load is not limited to the lighting fixture 49, and may be other devices that are turned ON / OFF by a switch.

[1-3-1. (Configuration of relay unit)
Next, the relay unit 10 will be described in detail. FIG. 4 is a circuit diagram showing a configuration of the relay unit 10. FIG. 4 illustrates one relay unit 10.

The drive unit 102 b includes a light emitting semiconductor element, and stops light emission / light emission based on an ON / OFF control signal given from the control circuit 43. As the semiconductor relay 102, a photo MOS relay or a relay in which a light receiving type and a light emitting type semiconductor element are configured by an optical coupling element (such as a phototransistor coupler or a phototriac coupler) can be used.

  Thus, the relay unit 10 can reduce the current supplied to the exciting coil 101b by combining the electromagnetic relay 101 and the semiconductor relay 102. Usually, in order to drive the contact of the relay in order to connect and disconnect the power line PL that supplies power of 100 V (3 A), it is necessary to supply a large current of 80 mA to 100 mA to the exciting coil. For this reason, a dedicated power source is required for supplying current to the exciting coil. When such a relay is employed as the relay unit 10, it is difficult to reduce the size of the interior part group 34. Therefore, by using the semiconductor relay 102 as in the relay unit 10 described above, the contact 101a can be driven by supplying a current of about several mA from the power line PL to the exciting coil 101b. Therefore, another power source is used. There is no need.

  The remote control data is data for remote control operation used for remote control performed by a remote control unit 532 described later. This remote control data is a code formed in a predetermined format.

  The load capacity data is data of the load capacity of the lighting fixture 49 and is acquired by a load capacity acquisition unit 552 described later. This load capacity data is used by the power integration processing unit 55 to calculate the integrated value of the power consumption of the luminaire 49. As the load capacity data, a known rated load for the lighting fixture 49 is used, but a value calculated based on a load current measured as described later may be used.

  The energization time data is data of a time during which the relay units 10 of each system are in conduction, and the time is measured by an energization time measurement unit 551 described later. This energization time data is also used for the power integration processing unit 55 to calculate the integrated value.

  The program memory 432b stores a control program for realizing the function of each unit of the control unit 51 described later. This control program is not limited to a program defined in advance, but may be a program acquired from the mobile phone 47 by infrared communication.

This operation will be described in detail with reference to FIGS.

  FIG. 8 is a block diagram showing the configuration of a system for transmitting and receiving mails with audio data attached between different switch units 1. FIG. 9 is a flowchart showing a procedure of processing for transmitting / receiving the mail between different switch units 1 in the system.

  First, the above system will be described. In this system, the switch unit 1 on the transmission side is the terminal A and the switch unit 1 on the reception side is the terminal B. The mail transmitted from the terminal A is transmitted to the Internet via the wireless LAN router 48 and stored in the mail server 201. When receiving mail at the terminal B, the mail stored in the mail server 201 is transmitted to the terminal B via the Internet.

  Next, an operation for transmitting the mail in the system configured as described above will be described.

  First, a message is recorded by the user at terminal A (step S1). The recorded voice data is temporarily stored in the data memory 432a. Then, when a mail for transmission is created by the voice mail processing unit 542, the mail is transmitted with the voice data attached (step S2). Thus, when the mail is transmitted to the designated mail address, the mail is temporarily stored in the mail server 201. This mail includes the sender's self-authentication code.

  Next, if the terminal B confirms whether or not the mail server 201 has received a mail at regular intervals, if a mail is received, the mail is received by the terminal B (step S3). Here, it is determined whether or not the destination of the received mail is appropriate (step S4). At this time, the voice mail processing unit 542 confirms whether or not the self-authentication code included in the received mail is an appropriate self-authentication code registered on the B terminal side.

  If it is determined in step S4 that the transmission destination is appropriate, the voice mail processing unit 542 temporarily stores the voice data attached to the mail in the data memory 432a (step S5). Then, the voice mail processing unit 542 determines whether or not the playback condition specified by the playback condition command included in the mail is satisfied (step S6).

  If it is determined in step S6 that the playback condition is satisfied, the stored voice data (message) is played back by the voice processing unit 523 (step S7), and the process ends. If it is determined in step S4 that the transmission destination is not appropriate, the process ends.

  Thus, if the reproduction condition is the lighting operation (ON operation) of the luminaire 49, the voice data is reproduced and the message can be transmitted by voice by performing the ON operation in the switch unit 1 on the mail receiving side. .

[2-6. (Integrated power calculation)
