Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a power line carrier control system that transmits a load control signal via a power line of a commercial power source.

[Background technology]

Conventionally, this type of power line carrier has a central operation panel that transmits a control signal to control the load using a central operation switch, and a terminal device that receives the control signal transmitted via the power line and controls the load. Since the control system was developed as a control system that would be installed as needed in existing houses, a terminal device would be installed separately from manually operated switches such as recessed wall switches that control lighting loads, etc. It was becoming like that. However, when installing this type of control system when constructing a new house, there is a problem in that the manual operation switch and the terminal must be installed separately, making the installation complicated. In other words, it is necessary to secure separate space for arranging the manual operation switch and the terminal device, and in the case of recessed downlights and direct-mounted lighting equipment, it is necessary to take the trouble to provide a control box for arranging the terminal device. In addition, there was a problem in that the manual operation switch and the terminal were wired separately, making the wiring work cumbersome.

[Purpose of the invention]

The present invention has been made in view of the above points, and provides a power line transport control system that can easily secure installation space and simplify wiring work by integrating a manually operated switch into a terminal. It is about providing.

[Disclosure of the invention]

(Embodiment) FIGS. 1 to 6 show an embodiment of the present invention. In the figure, reference numeral 1 denotes a central operation panel embedded in a wall, and has central operation switches 10a, 10b, etc. for controlling loads 3 such as lighting loads.
By pressing b..., a control signal V _C for controlling a predetermined load 3 is transmitted. This control signal V _C
As shown in FIG. 7, is a high frequency signal for time-division multiplex transmission of a start mark, address data for selecting a load 3 to be controlled, control data for controlling the load 3, and an end mark. ,
Each bit of both data is transmitted synchronously with each half cycle of the mains power AC. This centralized operation panel 1 has an intercom device, a clock, and a disaster prevention monitoring device integrated into it, and 11 is a handset for the intercom, 12 is a time display part of the clock, and 13 is a disaster prevention device that displays fire, gas leak, etc. 14 is a set/reset switch for the security device; 15 is an emergency switch for notifying outsiders of the occurrence of an emergency when pressed in an emergency; 16
1 is a volume for adjusting the volume of various alarms, and 17 is a speaker. Reference numeral 2 denotes a control terminal device that receives a control signal V _C transmitted via the power line l of the commercial power source AC and controls a load 3 such as a lighting load, and the terminal device circuit 2a is connected to the power supply section 20. , modem section 2
1, a logic processing section 22, and a load control section 23. Reference numerals 5a and 5b are manually operated switches disposed on the front panel 4a of the housing 4 that houses the terminal circuit 2a, and the load 3 is controlled based on the states of the manually operated switches 5a and 5b and the received control signal V _C. It is becoming more and more controlled.
Here, the power supply unit 20 steps down the commercial power supply AC, rectifies and smoothes it, and forms a circuit power supply. The modem unit 21 transmits data superimposed on the commercial power supply AC. The control signal V _C consisting of a high frequency signal is separated to demodulate address data and control data, and the high frequency signal is modulated with the return data output from the logic processing section 22 to form a return signal V _B. Logic processing unit 22 formed using a microcomputer
is the control signal V _C input via the modem section 21
Compares the address data of and its own unique address set in the address setting section 22a,
When the two match, the following control data is captured and a load control signal based on that control data is generated.
While forming V _L and sending it to the load control section 23,
Return data is formed based on the operating status signal of the load 3 inputted to the monitoring input terminal and sent to the modem section 21. However, when the manual operation switches 5a, 5b are operated, the load control signal _VL is generated based on the states of the manual operation switches 5a, 5b, and by pressing the manual operation switch 5a, the load 3 is turned on, and the manual operation is performed. Load 3 is turned off by pressing switch 5b. In the load control section 23, a switching element controlled by a load control signal _VL drives a latching relay _RL , and its contact r
On/off control of load 3 is performed. In addition, when dimming the load 3, a bidirectional three-terminal thyristor may be used instead of the latching relay R _L , and in this case, the load control signal V _L becomes a phase control signal.
Further, the terminal device 2 is configured to be embedded in a wall using a wall switch mounting frame, and two electrical outlets 25 are arranged side by side using a mounting frame for two terminals.
Connected to this outlet 25 is a local control terminal 26 that allows the user to control the load 3 at hand, or a sub-intensive operation panel 27 that allows the user to selectively control a plurality of loads 3, 3, . . . .

28 is a control terminal device for controlling two or more loads 3, 3..., and the front panel shows each load 3, 3...
A manual operation switch (not shown) corresponding to 3... is provided. 29 is a terminal device for controlling the additional alarm device 30, and this terminal device 29 receives control signals.
It has only a V _C receiving function and controls the alarm device 30 with a relay contact. On the other hand, 31 is a monitoring terminal for transmitting return data indicating the status of security switches, fire, smoke detectors, gas detector output contacts, emergency push button switches, etc. to the central operation panel 1. It only has the function
The monitoring input section 31a is configured as shown in FIG. That is, in FIG. 6a, crime prevention switches 32a, 32b, etc., which are normally closed contacts, are connected in series, input is input to the monitoring input terminal of the monitoring terminal 31, and one of the crime prevention switches 32a, 32b, etc. is turned off. Therefore, a crime prevention signal (off signal) is inputted, and as shown in FIG. An emergency signal (on signal) is input when the switch is turned on, and the voltage output of the smoke detector 34 or the like is input to the monitoring input terminal in c of the figure. Reference numeral 35 denotes an alarm unit disposed at a location away from the central operation panel 1, which has the same configuration as the disaster prevention monitoring device having the disaster prevention display section 13 of the central operation panel 1, and issues an alarm with an indicator lamp and a buzzer. It's becoming like that.

40 is a distribution board in which a main breaker 36 and branch breaker groups 37 and 38 are arranged, and a block filter 39 is inserted between the branch breaker groups 37 and 38 to prevent high frequency signals from leaking to the outside. , each device constituting the power line transfer control system such as the central operation panel 1 and the terminal device 2, and a load 3 such as a lighting load are connected to the branch power line branched off via the branch breaker group 38 behind the block filter 39. Loads unrelated to the control system, such as refrigerators, air conditioners, televisions, and radios, are connected to the branch electrical circuits branched off through the branch breaker group 37. Therefore, compared to the case where the block filter 39 is inserted immediately after the main breaker 36, the current capacity of the block filter 39 can be reduced, and the noise removal circuit inserted in the current input circuit of a television etc. The control signal V _C is not attenuated.
