Abstract

<P>PROBLEM TO BE SOLVED: To provide a home automation system which can carry out the remote operation and remote state confirmation of terminal equipment not provided with an HA terminal, and its operation method. <P>SOLUTION: When the remote ON of an outdoor light 4 (lighting of the outdoor light for instance) is requested from a portable telephone 13 to a management center 11, the management center 11 commands energizing of the outdoor light 4 to a controller 3. In response to that, the controller 3 transmits JEM-A control signals to the energizing control circuit 6 of an HA conversion unit 2. The energizing control circuit 6 which receives the control signals supplies an energizing trigger to a relay circuit 8. In response to that, the relay circuit 8 closes the side of the contact 9b of a relay SW9 and opens the side of the contact 9a. Thus, the outdoor light 4 is lighted. <P>COPYRIGHT: (C)2006,JPO&NCIPI

FIG. 9A shows the transmission condition of the control signal, and a pulse of Tp = 200 to 300 ms is transmitted. The terminal device 101 reverses the operating state by this signal. The pulse interval is defined as Ti = 200 ms or more. FIG. 5B shows the monitor signal condition, and it is defined that the signal is inverted when Tr = 350 ms or less after receiving the control signal pulse. By monitoring this signal, it can be confirmed that the terminal device 101 has reversed the operating state.

For example, Patent Document 1 discloses an electric lock system using the HA remote operation system according to the JEM-A standard.
However, in order to remotely control terminal devices such as electric locks and air conditioners, these terminal devices need to be equipped with HA terminals, and remote control is required for devices and devices not equipped with HA terminals. There is a problem that can not be done.

  The HA conversion unit 2 mainly includes an energization control circuit 6, a relay circuit 8, a monitor signal output circuit 7, and an energization detection circuit 10. The energization control circuit 6 has a function of giving a trigger to the relay circuit 8 based on a control signal from the control signal transmission circuit 3 a of the controller 3. The relay circuit 8 opens and closes the relay SW9 in response to the trigger signal. The relay SW9 includes two contacts 9a and 9b. Photocouplers 17a and 17b are disposed between the control signal transmission circuit 3a of the controller 3 and the energization control circuit 6 of the HA conversion unit 2 and between the monitor signal monitoring circuit 3b and the monitor signal output circuit 7, respectively. It is comprised so that it may be insulated by.

The outdoor light 4 is provided with a switch 5 that can be operated independently of the relay SW9, and a stair switch is formed between the relay SW9 and the switch 5 by wires 16a and 16b.
A commercial power supply 15 is introduced into the HA conversion unit 2, and power is supplied to the outdoor lamp 4 through the relay SW 9 and the switch 5. An energization detection circuit 10 is disposed in the middle of the power supply line, and is configured to detect an energization state and transmit it to the monitor signal receiving circuit 7.

  The HA remote control system 1 is configured as described above. Next, remote control for the outdoor lamp 4 will be described. Referring to FIG. 2, when there is a remote ON request (for example, lighting of the outdoor lamp) of the outdoor lamp 4 from the mobile phone 13 to the management center 11, the management center 11 energizes the controller 3 with the outdoor lamp 4. Command. In response to this, the controller 3 transmits a JEM-A control signal to the energization control circuit 6 of the HA conversion unit 2. The energization control circuit 6 that has received the control signal gives an energization trigger to the relay circuit 8. In response to this, the relay circuit 8 closes the contact 9b side and opens the contact 9a side of the relay SW9. As a result, the circuit shown in the bold line in the figure is energized and the outdoor lamp 4 is lit.

  When the energization detection circuit 10 detects the energization state, a signal is transmitted to the monitor signal output circuit 7. In response to this, the monitor signal output circuit outputs a signal conforming to JEM-A to the monitor signal monitoring circuit 3 b of the controller 3. Therefore, when there is a remote state confirmation request from the portable terminal 13 to the management center 11, the management center 11 receives the monitor result from the controller 3 and transmits the contents to the portable terminal 13.

  Next, with reference to FIG. 6, the flow of remote status confirmation of the HA remote operation system 20 will be described. The controller 3 always checks the monitor signal of the switch strike 21 (S101). That is, when the contact 22 of the switch strike 21 is closed, the monitor signal monitoring circuit 3b → the communication line M1 → the switch strike contact 22 → the communication line M2 → the monitor signal monitoring circuit 3b is closed, and a signal current flows to monitor the signal. The monitoring circuit 3b is configured to detect opening and closing of the switch strike 21 by detecting this.

  When there is a request to confirm the locked state of the entrance door from the portable terminal 13 to the management center 11 (S102), the management center 11 transmits a monitor signal transmission command message to the controller 3 (S103). In response to this, the controller 3 returns the monitor signal state of the switch strike 21 (that is, opening / closing of the switch strike 21) to the management center 2 (S104). The management center 2 transmits the result of status confirmation to the mobile terminal 7 (S105), and the mobile terminal 7 receives this and displays the status on the screen (S106).
