It is a block diagram which shows the whole structure of the remote system of the load which concerns on Example 4, and a display part.

  Hereinafter, preferred embodiments of the present invention will be described in detail.

  First, Example 1 is demonstrated based on figures.

FIG. 1 is a block diagram illustrating an overall configuration of a remote control system for a load and a display unit provided in an operation terminal device including an operation switch for operating input / output of a load such as a lighting fixture.

  As shown in the figure, the remote control system for the load and the display unit includes a plurality of loads 1 to n made up of, for example, a lighting fixture or a ventilation fan, an operation terminal 1, a transmission unit 2, a control terminal 3, The timer 4 is composed of a power source 5 and a transformer 6. The operation terminal 1, the control terminal 3, and the timer 4 are connected to the transmission unit 2 through a two-wire signal line.

  For example, the operation terminal 1 is installed on a wall or the like away from the transmission unit, and displays an operation switch 1c on which a user performs an ON / OFF operation on a load such as a lighting fixture, and an ON / OFF state of the load. A display unit 1a and a display switch 1b for switching ON / OFF of the display unit are provided. FIG. 2 shows a front view of the operation terminal 1 viewed from the operation direction in a state of being attached to the wall.

  The display unit 1a is, for example, arranged at both ends of the operation switch 1c, and lights up an LED to display the state of a load to be controlled. Either one is lit when the load is on, When is in the OFF state, the other is lit. Furthermore, the LED that lights when the load is in the ON state is red, and the LED that is lit when the load is in the OFF state is green, so that the LED can be more easily recognized.

  The display of the display unit 1a is not limited to being performed by turning on the LED, but may be realized by using any display means such as a liquid crystal display.

  The transmission unit 2 associates the operation switch 1c and the display unit 1a of the operation terminal 1 and the control terminal 3 with addresses, and can individually recognize them, and responds to input information from the operation switch 1c, The load can be controlled via the control terminal 3.

  In the control terminal 3, a relay control unit (not shown) connected to the transmission unit 2 and a relay (not shown) connected to the load are arranged.

  The timer 4 makes a control request to the transmission unit 2 in accordance with a preset ON / OFF schedule of the display state of the display unit 1a.

The power supply 5 is connected to the transmission unit 2 and the transformer 6, the transmission unit 2 is driven by the supply of power from the commercial power supply, and the control terminal 3 and the timer 4 are supplied from the commercial power supply by the transformer 6. The electric power is driven by a power source converted so as to be suitable for driving the control terminal 1.

  Next, the operation of the remote control system for the load and display unit will be described with reference to FIGS. FIG. 3 is a circuit block diagram of the operation terminal 1, and FIG. 4 is a sequence diagram according to the present embodiment.

  For example, when the operation switch 1c of the operation terminal 1 is operated by the user when the load is in an OFF state, the control unit 1d calls an address assigned to the operation switch 1c from an address storage unit (not shown). Subsequently, a signal based on the address information is generated, and this signal is transmitted from the transmission unit 1g to the transmission unit 2. The transmission unit supplies a signal to a relay control unit (not shown) of the control terminal 3 in which the corresponding address is set from the transmitted address information, and the relay of the control terminal 3 is closed and the load is turned on. .

  On the contrary, when the load is in the ON state, when the user operates the operation switch 1c of the operation terminal 1, the relay of the control terminal is opened via the transmission unit in the same manner as described above. Is turned off.

  In this way, the load ON / OFF control is performed.

  Further, the control unit 1d of the operation terminal 1 extracts the relay address and the load operation information from the transmission signal received by the reception unit 1f from the transmission unit, and assigns the address to each operation switch 1c stored in the address storage unit. If any of the above is satisfied, a lighting signal is output to the display unit 1a based on the load operation information to change the emission color of the display unit 1a. Specifically, if the load corresponding to the address includes operation information indicating the ON state, the display unit 1a emits red light. If the load includes operation information indicating the OFF state, the display unit 1a emits green light. Thereby, the user can visually recognize the state of the load installed remotely from the operation switch.

The timer 4 is set with a time schedule in which the date and time for controlling each display unit 1a and the ON / OFF content of the display state are set in advance. (For example, a schedule is set for turning on the display state of the display unit from 9:00 to 17:00 from Monday to Friday)
Further, this system has a timer function as a timer means, and the timer 4 sets a schedule.

When the timer 4 reaches a time for turning on the display state of the display unit 1a in accordance with a preset schedule, the timer 4 outputs a signal requesting control for turning on the display state of the display unit 1a to the transmission unit 2. . The transmission unit 2 takes out the display unit control address corresponding to the display state of the corresponding display unit 1a, and outputs a signal for turning on the display state of the display unit 1a. When the operation terminal 1 corresponding to the display unit control address receives a signal via the receiving unit 1f, the control unit 1d turns on the display state of the display unit 1a.

  Further, when the time for turning off the display state of the display unit is reached, the timer 4 sends a control request to the transmission unit 2 to turn off the display state of the display unit 1a. A signal for turning off the display state is output.

  In this way, the ON / OFF of the display unit can be switched according to a schedule set in advance in the timer 4, which can contribute to energy saving.

  In addition, when the user himself / herself using the load determines that the lighting of the display unit 1a is unnecessary, when the display switch 1b of the control terminal 1 is turned off, the display switch 1b controls the control unit 1d. And the display state of the display unit 1a can be turned off.

  In this way, when it is not necessary to turn on the display unit 1a such as when it is absent, the display state of the display unit 1a is turned off remotely from the operation switch, thereby reducing power consumption during standby and contributing to energy saving. can do. Furthermore, convenience is improved because the user can turn on and off the display unit.

  Next, Example 2 will be described. FIG. 5 is a block diagram illustrating an overall configuration of a remote control system for a load and a display unit according to the second embodiment.

  The same components as those described in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and only different components are described.

  Reference numeral 7 denotes an entry / exit management system. When an employee's entry / exit is managed by an IC card or the like, the entry / exit information can be used.

  In this case, for example, when the information for entering the room is output from the entrance / exit management system 7, the contact interlocking (not shown) connected to the entrance / exit management system 7 and the transmission unit 2 turns on the display unit 20 a to the transmission unit 2. A signal requesting control to be output is output. The transmission unit 2 outputs a display unit control address corresponding to the load of the corresponding display unit and a signal for turning on the display state of the display unit, and the control unit of the corresponding operation terminal unit displays the display state of the display unit 20a. Turn it on. When the exit information is output, the transmission unit 2 is requested to control to turn off the display state of the display unit 20a, and the transmission unit 2 outputs a signal to turn off the display state of the corresponding display unit. .

  In this way, by controlling the display unit 20a using the entrance / exit management system, there is applicability compared to the case where the timer is used, and the convenience of the user is improved even when the load usage is irregular. Energy saving can be achieved without lowering. Furthermore, since the display unit is turned on according to the user's occupancy status, further energy saving can be achieved as compared with the case where a timer is used.

This human sensor 30h determines whether or not there is a person in the vicinity of the operation terminal device 1, and only when the person is in the vicinity, the control unit (not shown) of the operation terminal device 1 turns on the display state of the display unit 30a. A control request is sent to 30d to turn on the display state of the display unit 30a.

  In addition, the user can switch the validity / invalidity of the human sensor 30h by the human sensor switch 30i.

  FIG. 8 shows a sequence diagram thereof. As shown in the figure, when the human sensor 30h senses a heat ray by infrared irradiation within a predetermined distance, it makes an ON control request to the display unit 30a and turns on the display state of the display unit 30a. Yes. Further, when the human sensor 30h does not detect the heat ray, the display state of the display unit 30a is turned off.

  As described above, the display state of the display unit 30a can be turned on only when the user approaches the operation terminal 1 in order to control the load of a lighting fixture or the like, and the power consumption during standby is reduced. It can contribute to energy saving. Furthermore, by providing the human sensor switch 30i, it is possible to save energy by changing ON / OFF of the human sensor according to the situation such as the frequency of the human sensor and the confirmation frequency of the display unit 30a. However, it is possible to make the system in consideration of convenience.

  Next, Example 4 will be described. FIG. 9 is a block diagram showing the overall configuration of the load and display remote control system according to the embodiment.

Then, a control request is made to the transmission unit 2 in accordance with the ON / OFF schedule of the human sensor 40h.

  The human sensor timer 8 outputs a signal requesting the control to turn on the human sensor 40h to the transmission unit 2 when it is time to turn on the human sensor 40h set in advance. The transmission unit 2 takes out the control address of the human sensor 40h corresponding to the corresponding human sensor 40h and outputs a signal for turning on the human sensor 40h. When the operation terminal device 1 corresponding to the human sensor control address receives a signal via the receiving unit 40f (not shown), the control unit 40d (not shown) turns on the human sensor 40h.

  Further, when it is time to turn off the human sensor 40h, the human sensor timer 8 requests the transmission unit 2 to turn off the human sensor 40h, and the transmission unit 2 sends the corresponding human sensor 40h. A signal to turn off is output.

  In this way, ON / OFF of the human sensor 40h can be switched according to a schedule preset in the human sensor timer 8.
