Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a remote control device that enables manual control using a sub-operator regardless of control by a main controller.

(Prior art) Conventionally, this type of remote control device uses a main controller to send out control signals based on signals from an optical sensor and preset time control, monitors based on these control signals, and adjusts the settings in advance. When controlling other than the specified time control, it is known that each lighting zone is provided with an operation switch for manually controlling only that zone. However, manual control can only be performed in that zone.

Furthermore, as described in Japanese Patent Laid-Open No. 54-162865, for example, a switch having a temporary control function that changes from a pre-assigned load time control pattern to another control palette for a certain period of time is also provided. Therefore, there is known a device that performs different control only for the predetermined period of time. However, unless a certain period of time has elapsed or the switch is operated, it is unclear whether it is a preset control pattern or a temporary function.

On the other hand, by providing a sub-operator on the transmission line of the main controller,
Controlling a terminal device using both a main controller and an auxiliary controller is known, for example, from Japanese Patent Laid-Open No. 53-49683 and Japanese Patent Laid-Open No. 54-148972.

(Problems to be Solved by the Invention) However, when performing control other than preset time control, devices that perform manual control,
Manual control cannot be performed outside the zone where manual control is performed.

In addition, in the device described in Japanese Patent Application Laid-open No. 54-162865, if a certain period of time has elapsed or the switch is not operated, the control pattern is set in advance or the function is temporary. There are some unknown problems.

The present invention was made in view of the above problems, and
It is possible to change the control content of the main controller by sending a signal to manually control the terminal with the sub-controller to the main controller, and it is also possible to monitor the status of the terminal by receiving control signals from the main controller. The object of the present invention is to provide a remote control device that is inexpensive and easy to install by using a common transmission line.

is a main controller, and a terminal device 4 and a sub-controller 5, each connected to a load 3, such as a lighting device, are connected to the main controller 1, for example, via a dedicated two-wire transmission line 2. 4 and the sub-operator 5 are connected to an electric wire 6 for supplying electric power.

The main controller 1 has a microcomputer and a clock function, and the control level of the load 3 is programmed for each address, and the terminal 4 at a specific address is selected based on an external light detection signal from a light sensor (not shown) and the program. control signals are transmitted cyclically or randomly.
As shown in FIG. 5, this control signal is composed of a start signal S indicating the beginning of the control signal, an address signal A indicating the address of the terminal device 4 to be controlled, and a control content signal C indicating the control content. Then, a monitoring time W is provided for monitoring the manual control signal HC from the sub-operator 5 for a certain period of time after the control content control signal C, and if the manual control signal HC is not received during this monitoring time W, the control content signal C is changed. When the manual control signal HC is received instead, the control contents signal C at the same address thereafter is changed to the signal C (HC) instructed by the manual control signal HC, regardless of the program.

Further, as shown in FIG. 2, each terminal device 4 has a unique address and receives a control signal from the main controller 1, and if this control signal has the same address signal A as its own address, Receiving unit 11 that receives control content signal C following address signal A
For example, 100% lighting,
A dimming signal generating section 12 generates four types of dimming signals: 60% on, 30% on, and off, and a dimming signal from the dimming signal generating section 12 in response to the control content signal C from the receiving section 11. , and a dimmer 14 that controls the supply of power to the load 3 according to the dimming signal selected by the signal selection section 13.

In addition, as shown in FIGS. 3 and 4, the sub-operator 5 is formed by an address designation switch 16 as a terminal designation section in which correspondence is set in advance to the addresses of one or more terminal devices 4. Address designator 17, 100% lighting, 60% lighting, 30% lighting,
A control input operation unit 19 formed by a control input operation switch 18 for inputting control details for turning off the light.
, an address status display unit 21 as an address display unit formed by an address status display unit 20 provided corresponding to the address of the terminal device 4, and a control status indicator light 22 for displaying the control status. an input control section 24 that outputs a signal corresponding to the pressed address designation switch or control input operation switch 18 when each address designation switch 16 or control input operation switch 18 is pressed; , a transmitting/receiving unit 25 that receives a control signal from the main controller 1 according to a signal from the input control unit 24 and transmits a manual control signal HC.
and a display control unit 2 that lights up each display unit 20 and 22 in accordance with the control signal received by the transmitter/receiver unit 25.
It consists of 6. Further, in this embodiment, a manual control display section 27 is provided to indicate that control is being performed by its own manual control.

Next, the operation of the above embodiment will be explained.

First, normally, a control signal based on a program is transmitted from the main controller 1 to each terminal device 4 via a transmission line 2, and each terminal device 4 receives a control content signal of a control signal having an address signal A that is the same as its own address. C, and performs dimming according to this control content signal C.

In this state, if one wants to know the dimming state of a particular load 3, the user presses the address designation switch 16 of the sub-operator 5 corresponding to the address of the terminal device 4 to which the load 3 is connected. Then, the address corresponding to the pressed address designation switch 16 is input to the transmitting/receiving section 25 via the input control section 24. Then,
This transmitting/receiving section 25 takes in an address signal A that is the same as the address and a control content signal C of a control signal having this address signal A, and sends the address status indicator light 20 corresponding to this address signal A via a display control section 26. and the control status indicator light 22 corresponding to the control content signal C are turned on and displayed.

Also, regardless of the program of the main controller 1, if you want to make a certain load 3 turn on at 100%, for example, select the address designation switch 1 corresponding to the address of the terminal device 4 to which that load 3 is connected.
6 and the control input operation switch 18 corresponding to 100% lighting. Then, the addresses and operation contents corresponding to the pressed address designation switch 16 and control input operation switch 18 are input to the transmitter/receiver 25 via the input controller 24, and the transmitter/receiver 25 operates as shown in FIG. A manual control signal HC of 100% lighting corresponding to the operation content is transmitted to the main controller 1 during the monitoring time W of the control signal having the same address signal as the address. Then, the main controller 1 stores this address and the manual control signal HC, and as shown in FIG. HC) and send. Therefore, the terminal device 4 at the address turns on the load 3 at 100% by means of a control signal. Further, after transmitting the manual control signal HC, the sub-operator 5 transmits an address signal A that is the same as the address inputted to the transmitter/receiver 25, and a control content signal C (HC) of the control signal having this address signal A. The address status indicator lamp 20 corresponding to the address signal A and the control status indicator lamp 22 corresponding to the control content signal C are turned on and displayed via the capture and display control unit 26. Also, the manual control display section 27 is turned on.

Note that the control content signal C (HC) of the control signal
continues until it is manually controlled again by the sub-operator 5 or until all manual operations are canceled by a preset program of the main controller 1. By automatically canceling the manual control state using the main controller 1, it is possible to automatically return to the manual control state if the user forgets to return to the manual control state.

In the above embodiment, the sub-operator 5 is provided with an address designation switch 16 corresponding to the address of each terminal 4 and an address status indicator light 20, so that the status of each terminal 4 can be manually controlled and displayed. However, it is also possible to allocate each terminal device 4 to each zone and provide the sub-operator 5 with a zone designation switch and a zone status indicator light so that manual control and display can be performed for each zone. In this case, the manual control signal HC for each zone is determined by the monitoring time W of the control signal having a predetermined address signal, for example, the first
The zone manual control signal HC has an address signal of 48.
At the monitoring time W when , the manual control signal for the second zone
HC is transmitted from the sub-operator 5 to the main controller 1 during the monitoring time W when the address signal A is 49. When the main controller 1 receives the manual control signal HC for each zone, it converts the control content signal C of the control signal having the address signal A of the terminal device 4 assigned to this zone into the signal C specified by the manual control signal HC. (HC) and send. Also,
The transmission line can also be a power line instead of a dedicated line.

〔Effect of the invention〕

According to the present invention, the control status of each terminal device from the main controller can be displayed on the sub-controller, and each terminal device can be manually controlled by operating the sub-controller regardless of the program of the main controller. The device can be installed in a place where the load status cannot be seen at all. For example, by installing a sub-control device at the entrance of a building, people who use each room or each floor of this building can check the room they are using at the entrance. The lighting status can be known and manual control can be performed as necessary.

In addition, the sub-operator is installed on the same transmission line as the terminal unit, and the manual control signal is transmitted and the control signal from the main controller is received via this transmission line, so there is no need for a special transmission line, and the cost is low. In addition, construction can be simplified, and since each terminal designation section has a common transmitting and receiving section, the remote control device itself can be downsized.

Furthermore, by operating any terminal designation section, the control status of the corresponding address is read out and the control status display section lights up, so you can check which control state the desired terminal is in by operating the terminal designation section. By operating any terminal designation section and any control input operation section, you can write the control state during the monitoring time of the corresponding address, rewrite the control state with the main controller, and write the control state to the terminal designation section. If the same control signal as the control input operation section is sent from the main operation device, this control signal will be read and the corresponding address display section will be displayed.
The operation of the main controller or the sub-controller can be easily identified from the state of the address display section without operating the terminal designation section, and can also be used when only the terminal designation section is operated. Furthermore, since the control signal from the main controller is received and displayed, it is possible to increase the consistency between the control state of the terminal and the displayed content.
