In the embodiment shown in fig. 1, the home control terminal can be installed in a building surface through a base 400, which can be installed in any suitable place in the home and placed against a wall surface, and the base 400 has an input terminal and an output terminal for connecting an external transmission network of the home and an internal transmission network of the home, respectively, and these transmission networks can be an electric bus mode or a media transmission network mode. In one embodiment, the body portion of the base 400 has a square configuration such as that shown in fig. 1, but other shapes are possible, and the base 400 has an extension member 420 for extending or receiving the body portion of the base 400 (for example) in the direction T2 into a receiving space 500 provided on a building surface. Wherein an input and an output for coupling the above-mentioned home external transmission network and home internal transmission network are provided in the extension part 420. In another embodiment, the power cable 410 for coupling the input and output ends can be co-coated and led out from the central position of the base 400, which has the effect of avoiding wire connection interference caused by complicated wires.

In one embodiment, the extension member 420 may be provided with a swivel structure for allowing the body portion of the base 400 to swivel relative to the extension member 420 in the plane thereof. For example, when a plurality of bodies 100 or 200 of the home control terminal are fixedly installed in the T3 direction on the base 400 shown in fig. 1, the bodies 100 or 200 may be adjusted to a proper angular position according to the rotating operation in order to facilitate the installation angle, for example. Alternatively, the body portion of the base 400 may rotate around the center of the hole of the power cable 410.

In one embodiment, the home control terminal further includes a body fixedly installed on the base 400, wherein the body may include a first body 100 and a second body 200, and the first body 100 is stacked with respect to the second body 200. Wherein, the bottom end of the first body 100 for installation is provided with an engagement member 102 that mates with the top end of the second body 200. Such as plug and socket style pluggable coupling components. It will be appreciated that more bodies may be engaged with each other in this stacked manner.

For example, as a modification, the first body 100 is configured to mount a plurality of data signal control boards 101, and the second body 200 may be configured to mount a plurality of power signal control boards 201, and in one implementation, the plurality of data signal control boards 101 or power signal control boards 201 may be inserted in parallel along the direction T2' into slots disposed in parallel in the first body 100 or the second body 200, respectively. Among them, the data signal control board 101 and the power signal control board 201 may have different circuit configurations and be separately provided due to differences in the used voltage levels, for example. For example, the power signal control board 201 may be configured to receive ac power from a mains power line and control the supply of the ac power (e.g., 220VAC power) to electrical devices in the home.

Referring again to fig. 4 and 5, in one embodiment, each power signal control board 201 is provided with a drive circuit 158 for energizing and controlling an ac voltage for an electrical function required for an electrical appliance, such as a heater for an indoor floor heating, or a motor for a motorized window treatment. In one implementation, since such power signal control boards 201 are centrally disposed in the second body 200, the second body 200 will be mounted closer to, for example, the power leads L-line 411 and N-line 412, such that the power leads L-line 411 and N-line 412 can be provided to the second body 200, and the second body 200 can be provided with a power source therein for stepping down the ac power to various dc power sources that can be provided to the first body 100 through the bonding member 102.

In another embodiment, in addition to the power signal control board, a power control board is disposed in the second body 200, and a power supply 159 is disposed on the power control board, where the power supply 159 includes a main power circuit, a transformer U1, and a secondary power circuit. The main power supply circuit and the auxiliary power supply circuit can be mutually and electromagnetically coupled through a transformer U1, the main power supply circuit obtains alternating current from a 220V power grid alternating current power supply and converts the alternating current into direct current in a turnover mode, the transformer U1 reduces the 220V alternating current from the main power supply circuit to 12V, and the auxiliary power supply circuit rectifies the reduced 12V alternating current and can further reduce the voltage to 5V.

The primary power supply circuit and the secondary power supply circuit of the power supply 159 are configured to supply power to the transformer U1 having a structure insulated from each other via the primary side and secondary side circuits. With this configuration, the main power supply circuit and the sub power supply circuit are insulated from each other. As such, each of the power signal control boards includes the above-described driving circuit 158 configured to supply the alternating current of the main power circuit of the power source 159 to the alternating current driving circuit of each of the indoor electric devices, for example, the motor of the motorized window treatment or the heater of the bathroom, and supply the direct current of 12V or 5V of the sub-power circuit of the power source 159 to the data signal control board 101 in the first body 200.

For example, in the embodiment shown in fig. 5, an example of implementation of such a power supply 159 is given. Wherein certain components contained in the power supply 159 are labeled for purposes of facilitating a more specific description of the manner in which such power supply is disposed. For example, transformer U1 may use an industrial frequency transformer, one effect of which is to be able to subject power supply 159 to larger voltage fluctuations, such as over-voltages. The transformer U1 steps down the 220V ac power from the main power supply circuit to 12V, and the sub power supply circuit rectifies the stepped-down 12V ac current through the rectifier bridge D11 and may further step down to 5V through, for example, a DC-DC converter and a voltage regulator as shown.

According to one embodiment of the present invention, the data signal control board 101 may be configured to connect some electrical devices through an in-home transmission network, an example of which may be a network constructed in a ZigBee, RS485, or Wi-Fi manner. To achieve this configuration, each data signal control board 101 is provided with a processor unit 143 configured to construct the in-home transport network.

For example, a home control terminal may include one or more processor units 143, such as a Digital Signal Processor (DSP) or Microprocessor (MCU), and references to "processor," "control circuitry," etc. in the illustrative description of the invention should be understood to encompass not only computers having different architectures such as single/multiple logic control structures and serial/parallel structures, but also specific analog/digital integrated circuits such as Field Programmable Gate Arrays (FPGAs), application specific circuits (ASICs), signal processing devices, and other processing circuitry devices. References to computer programs, instructions, code etc. should be understood to encompass software or firmware for programmable control circuitry, for example, whether a hardware device for the control circuitry has programmable content of instructions, or configuration settings for fixed function devices, gate arrays or programmable logic devices etc.

In one example, any of the processor units 143 described above may have a built-in memory for storing a computer program that performs the transmission functions described above in conjunction with the processor unit.

Meanwhile, the memory may store multimedia data or forwarding data content from other user devices, which may be in the form of data sets. The memory stores a computer program comprising computer program instructions/code that, when loaded into the processor unit, control the operation of the home control terminal.

The computer program code provides the logic and routines that enables the home control terminal to perform at least a portion of the methods of the present invention. The processor unit is capable of loading and executing the computer program by reading the memory. Although the memory is shown as a single component, it may be implemented as one or more separate components, some or all of which may be integrated/removable and/or may provide permanent/semi-permanent/dynamic/cached storage.

In addition, the processor unit 143 may respond to or call an application or a device driver by performing an operation of the home user, or an instruction of input/output system (BIOS) firmware and some firmware modules. At the same time, the processor units may cooperate on a serial bus, e.g., one of the processor units may act as a "coprocessor" for the other processor unit via the serial bus.

Referring again to fig. 5, in one example, the processor unit 143 may include a communication circuit 141 electrically coupled thereto, and the communication circuit 141 may be a chipset configured to generate data transmissions according to control logic instructions of the processor unit. In another example, the processor unit also includes an integrated circuit or chipset (e.g., a memory array) for coupling to other components of the home control terminal via the processor bus. The chip assembly may also couple the processor unit to BIOS firmware, which may include code executable during system start-up of the home control to initialize or reset the processor unit or its chip assembly, via one or more system buses. In another example, the communication circuit 141 may include a communication interface and a modulation/demodulation circuit configured to couple the processor unit 143 via a system bus to modulate and carry waveforms of data signals according to the control logic instructions and to transmit the waveforms via the communication interface. The communication circuit 141 may receive a data signal from, for example, a home internal transmission network via a communication interface, demodulate the data signal by a modulation/demodulation circuit, and transmit the demodulated data signal to the processor unit 143 or the memory via the system bus.

The processor unit 143 may further include coupling the processor unit 143 to a plurality of media devices, which may include video or audio input/output devices, network interfaces, which may include LAN controllers, modems, etc., or other I/O devices, through the one or more system buses. The I/O device may include an attachment device, such as a keyboard.

Referring back to fig. 1, the home control terminal further includes a cover plate 300 for enclosing the first body 100 and the second body 200, so that the data signal control board 101 or the power signal control board 201 can be insulation-packaged. The cover plate 300 may be made of any insulating material, such as resin or plastic. In the example shown in fig. 1, the cover plate 300 may be removed from or fastened to the periphery of the integral component formed after the first body 100 and the second body 200 are coupled in the direction T2. In a side view of such a home control terminal integral construction shown in fig. 2, it can be intuitively seen that the first body 100 and the second body 200 are assembled with each other to form a column-shaped integral part, which is then fixedly mounted on the base 400, and the cover 300 encloses three side elevation surfaces of the integral part and does not enclose a portion of the base 400, so that the integral part can be rotated left and right with respect to the base 400 to adjust an operation angle desired by a user.

In one embodiment, the home control has a user operation interface 110, and the user operation interface 110 may have a touch panel 120 for visually displaying operations configured to receive and recognize user inputs. Preferably, the touch panel 120 is removable from the user interface 110, for example, removable or insertable in the direction T3. In the embodiment shown in fig. 1 and 2, the user operation interface 110 may have an adjustment mechanism for adjusting the tilt angle of the touch panel 120 according to the observation angle of the user or, for example, the height of the user.

Further, the touch panel 120 further has a bending member 121 and a fixing member 122 coupled to the bending member 121 and extending along the bending member 121 for fixing the touch panel 120 within the user operation interface 110. In one example, touch panel 120 may have a processor unit, such as a Digital Signal Processor (DSP) or a Microprocessor (MCU) or a logic circuit or a set of circuits for a particular operation function. After the touch panel 120 is removed from the user operation interface 110, a wireless communication connection may be performed with the first body 100, for example, a data signal control board 101 for identifying and communicating with a processor unit of the touch panel 120 is installed in the first body 100, and the data signal control board 101 is configured to be activated after the touch panel 120 is removed.

Referring again to fig. 3, in one implementation, the first body 100 may be removable from the second body 200 and used as a separate operating component, or the second body 200 may be removable from the integral component, in accordance with one embodiment of the present invention. For example, the first body 100 may be used as a mobile device alone, which has the effect of satisfying the function of a home user to control some electric devices at any time at a desired location, or may be to withdraw the power signal control board 201 in the second body 200 while placing other electric devices, such as an air quality detecting device or a mobile air conditioner fan, therein. In one effect, since the interfaces corresponding to each control board are unified and universal, the power supply can be conveniently plugged in when the air quality detection device is installed, for example, so that the home control terminal can be moved to realize the functions required by the user. In the implementation shown in fig. 3, the portable device may be used as a mobile device with a power take-off cable 190 for taking ac current through, for example, a socket panel 500, while a roller 140 is mounted at the bottom of the integral unit to move the home control terminal.

Referring to fig. 6, in another embodiment, the home control terminal has only the first body 100, and the first body 100 may have the length of the integral part of the previous embodiment, and the first body 100 is fixedly installed on the base 400. Wherein the first body 100 is configured to mount a plurality of data signal control boards 101, in this embodiment, the data signal control boards 101 may include the aforementioned power signal control boards 201, and in one implementation, the plurality of data signal control boards 101 may be inserted in parallel into corresponding slots disposed in parallel within the first body 100. Wherein each of the data signal control boards 101 may have a different circuit configuration and be separately provided due to a difference in the used voltage level, for example.

In addition, the home control terminal further includes a cover plate 300 for enclosing the first body 100, so that the data signal control board 101 can be insulated and packaged. The cover plate 300 may be made of any insulating material, such as resin or plastic.

For example, each data signal control board 101 may have an electrical power take-off interface 157 and a data access interface 155 (e.g., backplane connector) disposed thereon in isolation, wherein the electrical power take-off interface 157 may be configured to receive ac power from the power grid power line and control the supply of the ac power (e.g., 220VAC power) to electrical devices within the home. The data access interface 155 is configured to receive multimedia data from a bus (e.g., WLAN cable 413) laid down in a building surface such as that shown in fig. 1. Wherein, the power taking slot 154 and the data slot 156 adapted to be plugged with the power taking interface 157 and the data access interface 155 are provided at one side of the housing cavity 150 in the first body 100, it should be understood that if the power taking interface 157 and the data access interface 155 are provided on the same circuit board, the power taking slot 154 and the data slot 156 are provided on the same straight line height, and the technician can set the arrangement positions of the interfaces in a respective familiar manner, but provided that a convenient manner of parallel plugging is required.

Referring again to fig. 4 and 5, fig. 4 schematically illustrates the design principle of the data signal control board 101 of the present invention, and fig. 5 illustrates an example of the design on a power supply in more detail.

In one embodiment, each data signal control board 101 may be provided with a drive circuit 158 for energizing and controlling an ac voltage for an electrical function required for use by a household appliance, such as a heater for indoor floor heating, or a motor for a motorized window treatment. In one implementation, the respective integrated circuits of the power take-off interface 157 and the data access interface 155 may be electrically isolated or by providing total electrical isolation at the power take-off slot 154 and the data slot 156 within the first body 100, such that the respective integrated circuits of the power take-off interface 157 and the data access interface 155 may not require insulation isolation.

For example, in addition to the power signal control board, a power control board is disposed in the first body 100, and a power supply 159 is disposed on the power control board, where the power supply 159 includes a main power circuit, a transformer U1, and a secondary power circuit. The main power supply circuit and the auxiliary power supply circuit can be mutually and electromagnetically coupled through a transformer U1, the main power supply circuit obtains alternating current from a 220V power grid alternating current power supply and converts the alternating current into direct current in a turnover mode, the transformer U1 reduces the 220V alternating current from the main power supply circuit to 12V, and the auxiliary power supply circuit rectifies the reduced 12V alternating current and can further reduce the voltage to 5V.

The primary power supply circuit and the secondary power supply circuit of the power supply 159 are configured to supply power to the transformer U1 having a structure insulated from each other via the primary side and secondary side circuits. With this configuration, the main power supply circuit and the sub power supply circuit are insulated from each other. As such, each of the data signal control boards 101 includes the above-described driving circuit 158 configured to supply the alternating current of the main power circuit of the power source 159 to the alternating current driving circuit of each of the indoor electric devices, for example, the motor of the motorized window treatment or the heater of the bathroom, and supply the direct current of 12V or 5V of the sub-power circuit of the power source 159 to the data signal control board 101 in the first body 200.

For example, transformer U1 may use an industrial frequency transformer, one effect of which is to be able to subject power supply 159 to larger voltage fluctuations, such as over-voltages. Switching power transformers can also be used, resulting in less cost and space for the design. The transformer U1 steps down the 220V alternating current from the main power supply circuit to 12V, and the sub power supply circuit rectifies the stepped-down 12V alternating current through, for example, a bridge rectifier circuit D11 and may further step down to 5V through, for example, a DC-DC converter and a voltage regulator.

In addition, in one embodiment, in order to effectively excite and control the ac voltage of an electric function required for use of a home appliance, each of the data signal control boards 101 may be provided with an on-off circuit 144, such as a relay, the on-off circuit 144 being provided across the above-mentioned main power supply circuit and sub-power supply circuit, the on-off circuit 144 being further coupled to a switch 160 on the side of the main power supply circuit for maintaining the power supply to the transformer U1 when the ac power supplied to the home appliance is turned off. In one implementation, a protection circuit 153 coupled to the drive circuit 158 is also provided when the relay is the on-off circuit 144 for absorbing back emf generated, for example, during the on-off of the contact c of the relay. Examples of the protection circuit 153 may be a transistor cut-off element such as a diode. In this case, the contacts a and b of the relay are connected to the L line and the N line of the power grid, respectively, and it should be understood that the home appliance device is connected between the contacts a and b. The relay will be controlled by the drive circuit 158 to disconnect the contacts a and b upon receipt of an on-off pulse from the processor unit 143, so that the power supply of the household appliance is cut off, whereby ac current acquisition of the power supply 159 can be maintained by the switch 160.

Referring again to fig. 6, another example of the data signal control board 101 may be provided as an integral unit, where "integral unit" is described herein as a generic term indicating a component or circuit that may be used independently or removed and then used as a stand-alone functional device, the integral unit comprising components that are not typically arbitrarily separable. In order to achieve this, a plurality of guide grooves 151 may be provided on the side wall of the accommodating chamber 150 in the first body 100, for receiving the outline configuration of the housing 131 of each data signal control board 101. Preferably, each guide rail groove 151 is provided with a sliding member 152 for facilitating the insertion stroke of the housing 131, and it should be understood that the guide rail grooves 151 and the sliding member 152 thereof are varied according to the size of the housing 131, and a plurality of guide rail grooves 151 are provided in parallel.

In the illustration of fig. 6, the plugging manner of each data signal control board 101 can be visually presented according to the indication of the direction of the dashed line O-O' in the figure. The circuit board of the data signal control board 101 can be designed in a manner that is approximately shown by the figure. In one embodiment, the circuit board of each data signal control board 101 may include a processor unit 143, a data access interface 155, a power access interface 157, and a driver circuit 158, wherein the driver circuit 158 is in turn coupled with the on-off circuit 144 and the protection circuit 153.

In another embodiment, the housing 131 may include a top cover 132 and a bottom 134 that are mated to each other, and may include a front cover 141 that is configured to nest the top cover 132 and the bottom 134. Preferably, the front cover 141 may be provided with an input device 121 (e.g., a key) for directly and manually controlling the electrical functions of each data signal control board 101 and an indicator 111 for indicating the operation state of each data signal control board 101, and the back side of the front cover 141 is provided with a circuit board 142 for providing the input device 121 and the indicator 111, and the circuit board 142 may be connected to the processor unit 143 through a port 135 provided on the circuit board of each data signal control board 101 to perform operations such as a hot start/stop operation. It should be appreciated that the front cover 141 of the housing 131 of each data signal control board 101 may be identical in size.

Referring to fig. 7, in yet another embodiment, each port of the data access interface 155 (e.g., backplane connector) will be defined by the processor unit 143 by the electrically coupled communication circuit 141. In one example, the data access interface 155 has 8 ports T1-T3, N1-N5, where the ports T1-T3 are configured to identify the DC current of the power supply 159, and the ports N1-N5 may be configured to identify the type of communication protocol for the in-home transport network described above, an example of which may be using ZigBee, bluetooth or Wi-Fi protocols. Wherein each port may be connected to an external network device 181-186. In addition, the power-taking interface 157 may include ports P1-P3, wherein P1 and P2 are respectively used for coupling the AC power line L of the main power circuit _in And L _out And (3) grounding E. In one implementation, the integrated circuits of each of the power take-off interface 157 and the data access interface 155 may be electrically isolated or may be electrically isolated by the power supply 159 at the power take-off slot 154 and the data slot 156 within the first body 100, such that the integrated circuits of each of the power take-off interface 157 and the data access interface 155 may not require an insulating isolation arrangement.

In addition, the communication circuit 141 is configured to allocate a corresponding number of ports to interface redundancy occurring in the data access interface 155. For example, in the initial state, the data access interfaces 155 of each data signal control board 101 are connected in a serial bus manner. In the example shown in fig. 7, one port N1 of one data signal control board 101 is a network interface for adapting to an external network device 181, such as a Wi-Fi network, and the corresponding ports N1 on the other data signal control boards 101 are all configured to adapt to the Wi-Fi network, and are configured by serial bus. Likewise, the other port N2 of the data signal control board 101 is used for a network interface adapted to the external network device 182, such as a ZigBee network. Alternatively still, one of the ports N4 is used for a network interface adapted to the external network device 184, such as Bluetooth, so that if the number of ports per data access interface 155 is sufficient, no interface redundancy will occur and typically one port type may be defined for each of the ports N1-N5 of the data transfer protocol.

In some cases, when one data transmission protocol type needs to occupy multiple ports N1 to N5, and if there are multiple transmission protocol types in one data signal control board 101, the number of ports will be insufficient, i.e. the "interface redundancy". In this case, the processor unit 143 is configured to acquire the unoccupied ports of the other data signal control boards 101 and the protocol types of the ports thereof; and changing the protocol type of the unoccupied port to the protocol type corresponding to the interface redundancy. For example, in the case where the network interface using the external network device 186 is an RS485 bus and other multi-line buses, if the interface redundancy occurs and the data transmission protocol of the required interface is RS485, the initial protocol type of the port such as the blank port shown in fig. 7 may be changed to be adapted to RS485 (the port occupied in the figure is denoted by ""). As such, the processor unit 143 of each data signal control board 101 may be configured to receive requests from the communication circuits 141 of other data signal control boards 101 indicating interface redundancy and to find the unoccupied ports of their corresponding data access interfaces 155 and their protocol types.

Referring again to fig. 6 and 8, in yet another embodiment, a baffle 171 may be disposed within the bottom cavity 170 of the first body 100, wherein a plurality of regularly arranged (e.g., parallel) baffle members 172 (e.g., suction fans) are disposed on the baffle 171 for drawing the gas 321 from the bottom cavity 170 into the receiving chamber 150 and diffusing the gas 321 toward the top of the receiving chamber 150. In addition, through holes 133 are formed in the top cover 132 and the bottom plate 134 of each data signal control board 101 corresponding to each other (the through holes in the bottom plate 134 are blocked at the illustrated positions and are not shown), so that the gas 321 drawn into the accommodating chamber 150 penetrates each through hole 133 to carry heat energy on the data signal control board 101 after the plurality of data signal control boards 101 are loaded into the accommodating chamber 150.

Referring further to fig. 8, a plurality of flow guiding grooves 130 are formed in parallel on the sidewall of the first body 100, for discharging the gas 322 with heat energy out of the first body 100. In one example, the cover plate 300 forms a slot 320 with the sidewall of the first body 100 after the first body 100 is sealed, and the gas 322 with thermal energy is exhausted from the back side of the first body 100 (i.e., the side not sealed by the cover plate 300) along the slot 320. In one implementation, the heated gas 322 is exhausted from a limited area because air 321 will also flow into the slot 320. In addition, the slots 320 are designed to provide a greater airflow rate after the gas 322 is exhausted into the slots 320, thereby avoiding the accumulation of thermal energy near the slots 320 or the channels 130 that would be detrimental to efficient heat dissipation.

In one embodiment, the processor unit 143 may be further configured to control the rate of operation of the flow guide member 172, for example, to change the rotational speed of the flow guide member 172 to draw a greater amount of gas 321 (e.g., air) to accelerate the heat energy carrying process when the temperature within the receiving chamber 150 is sensed to be above a threshold.

Further, each data signal control board 101 is further provided with a temperature sensor 173 coupled to the processor unit 143 for sensing the actual temperature of each spatial region in the accommodating chamber 150. For example, the thermal energy generated on some of the data signal control boards 101 may have different thermal energies for different ones of the data signal control boards 101, while the thermal energy generated on some of the data signal control boards 101 is carried by the drawn-in ambient air 321 (e.g., air), and does not need to be entirely supplied to the top of the receiving cavity 150 to be finally discharged out of the receiving cavity 150. In one example, if the temperature of one of the data signal control boards 101 is detected by the temperature sensor 173 therein to exceed a threshold value, the processor unit 143 is configured to control the rate of operation of the flow directing member 172 such that the gas 321 effectively reaches the location of that data signal control board 101. For this purpose, a baffle 171 is also provided at the top of the receiving chamber 150 for blowing gas into the bottom of the receiving chamber 150, so that the gas 322 carrying heat energy is discharged out of the diversion trench 130 by the air convection in different areas, i.e., different levels of the receiving chamber 150.
