:~EST MQ~ FOR CARRYING OUT T~l~ INVENTION
The embodiment of the l~resent invention will b~ describ~d
below with reference to the accoml~anying drawings.
~ WO ss/247s9 Z l ~ r~
FIG. 1 illustrate a switching s~stem in accordance with one
embodiment of the present inventioll. The switching s~stem of this
embodiment is made ul~ of controlling each load in differ~nt loc~ltions,
in the case that a l~lurality of loads are seParately installecl in at least
5 two or more l~laces blocked off from e~ch other. This embodiment
shows that five loads can be controlled in each location sel~arated fr(1m
others, resl~ectively. The switching system in accordance with the
l~resent invention coml~rises electronic switching means 100, which are
composed of l~lurality of switch sets. Each of switch sets is
10 sel~arately arranged in isolated l~laces, including remote controllers
and or contact switches. ~ince each of switch sets is in th~ same
form, a first set will be onl~ described h~reinafter. However, a
fourth set in the drawing has no a remote controLer. an~l a fifth set
can control only any one l~redetermined load without a remote
15 controller.
The first switch set coml~rises a remote control switch that is
l~rovided v~ith a remote controller 20A and a receiving l~orti()n :~OA for
converting c~ corresponding signal from th~ remote controller 20A int~l
an electric signal, and switches 31A~ 35A which are as many as hve
20 loads comlected between a l~ower su~ ly l~art and outl~ut terminals of
the receiving l~ortion 30A. Here, the remote controller 20A can eml~
all integrated circuit such as TC9148P, and the receiving l~ortiun 30A
can use an integrated circuit such as TC9149P or TC915ûP.
One of load controlling units 200A ~ 200E are sel~arately
25 connected to the outl~ut terminals of each switch set, only the first
unit 200A of which will be described as the load controlling units
200A ~ 200E have the same constitution. An OUtl~Ut terminal of the
first switch set is coupled to a signal transmitter 60 via a matrix 50
by insertion of a DIP switch 40. An outl)ut signal of the signal
30 transmitter ~i0 is sul~l~lied to a signal decoder 71 which decodes the
transmitted control signal. and then the decoded signal is provided to

WO 95124759 r~~ C,~ D1~ ~
a drivillg signal generator 73 which generates a driving signal to
control a correspollding load through matrix 72. The drivin~ signal
generator 73 controls each load according to the transmitt~d control
signal, to out~ t terminals of which transistors TRl~TRs as many as
5 five loads are coul led in series with Dhoto-coul~lers 41-45. Herc, th~
signal decod~r 71, matrix 7'2. driving signal generator 7.~ can employ
integrated circuits such as I~T3170, CD4028 and HD4027. resl~ectively.
On the other hand. a plurality of light emission diodes LED
which disl~lay a control state of each load are l~rovided to outt~ut
10 terminals of the d~-ivin~ signal generatur 73. Also, it is l~referred that
a DIP switcll 74 for manual control is l~rovided to the outl~ut t~rmin.~l
of the driving sigllal generator 73. In addition, a load selector 80,
coml~osed of ~ l~lurality of switches 81-85, is located between each of
transistors TR,-T~5 and l~hoto-coul~lers 41-45. When one of switches
15 of the load selector 80 is turncd on, a desircd load can be connect~d
to a corresDondin~ se~ Accordingly, if the first switch 81 of the
load selector ~0 is in an ~on" state and ~ control signal is sul)l~lied in
order to make a first load L, "on", a first transistor TR, is turncd on
and a first l~hoto- coul~ler 41 is ol~erated, thereby sul~l~lying thr l ~lwer
20 to the first load Ll.
On the othe]- hand, in the switching system in accordance with
the l~resent invention, alternating current l~ower is connected to zl first
load Ll through a first triac S~ as switching means. Also, second to
fifth loads L~- Ls are respectively arranged in l~arallel through second
25 to fifth triacs S~~Ss. Switches MSl-MSs are located between each of
triacs as electronic switching means and loads, and have functions of
controlling loads electronically and mrrh~nir~lly. Here, the electronic
switching means can utilize coil-type relay. When a first contactor
M, contacts with a first node (a), the load is electronically controlled.
30 When the first switch contactor M, contacts with a second node (b),
the load is mrrh,~llirally controlled. In a state that the first swit~h
W09s/247s9 ~ 3 ~ ::18
col1taetor M~ col1tacts with the second node (b), that is, in ~ n~ al
mechanical col1trc)l stat~, the secol1d switeh contaetor M~ l~lays a rol~
of turning on/off loads, for th~ role of whieh a tri-state mechanical
switch ean be eml~loyed.
A full-wave reetifier circuit BD~ that converts alternating current
into direct current is l~rovided to an alternating current inl~ut terminal.
A voltage stabilizer lO coul~led to an outl~ut terminal of the full-wave
rectifier eireuit BD Drovides l~uwer sul~l~ly to the system of the l~resent
invention. It can be easily understoc)d that direct current instead of
alternating current is used to accoml~lish techniques of th~ l~res~nt
invention .
F~~Fs not deseribed rel~resent fuses, whieh are installed in every
loads and l~revent damages due to the overload.
The ol~eration of the switching system in aceordance with onc-
embodiment of the l~resent invention will be deseribed below. First,
if the remote eontroLer 20A generates an infrared ray sign~l for
supl)lying the 170wer to the first load, the signal receiver .~OA receives
the infrared ray signal su~ lied from the remote eontrol~r 20A,
eonverts it to an eleetric signal and outl~uts the converted signal
through a first outl~ut terminal. The outl~ut signal is matehed through
the matrix 50 and modulated into a transmission signal in the signal
transmitter 60. The outl~ut signal of the signal transmitter 60 is
sul~l~lied to the signal deeoder 71, which decodes the transmitted
eontrol signal and l~rovides the deeoded signal to the driving signal
generator 73 which generates a driving signal to control the
corresl~onding load through the matrix 72. The driving signal
generator 73 drives the eorresl~onding LED and makes it to disl~lay
the load in aetion, and at the same time turns the first transistor TRl
'on'. Aeeordingly, driving of the first photo-eoul~ler 41 malces the
first triae S1 'on' and thereby the l~ower is supplied to the first load
Ll. Then, only the flrst switeh 81 of the load seleetor 80 is in an
-

'011' statc. This embodimellt selects a signal transmission metho(l by
coding. but methods by volt~ge difference or digit~l sign~lls m~y bc
em~loyed.
To understand the subject embodiment, a circuit which includes
the first remote conkoller 20A, first receiver 30A and first l~ush buttol1
switches 31A-35A, is disl~osed in a first chamber. A circuit which
includes the second remote controller 20B, second receiv~r 30B and
secoL1d l~ush butto~l switche~ 31B~35B, is disl~osed in a second
chamber. Such a constitution l~rovides to easily understc~nd the fact
that the second remote controller 20B installed in the second chamber
can control thc first l(~ad L~ in the first chamber.
FIGs. 2A to ''C are circuit diagrams of a switching system ill
accordance with other embodiment of the l~resent invention. When
coml~ared with the Pmhor:im~ont of FIG. 1, this embodiment is identical
to that of FIG.1 ~ ith th~ excel~tion that each of loads is controlled
through the driving sign~l generator 73 of the first chamber The
coml~onents which l~erform the same functions as in FIG. 1 are
n~2t~1 with th~ same reference numerals. Accordingly, the second
to fifth load conh-olling units 200B ~ 200E include only the signal
transmitters 60 each of which is connected to the signal decoder 71 of
the first load cont~ olling unit 200A. Thus, we can fully know that
even though any switch set of the electronic switching means 100
installed in any ch;lmber worlis, the identical signal is sul~l~lied to the
signal decoder 71 of the first load controlling unit 200A via the signal
transmitter (;0 of t~le load controlling units 200A~200E connected with
each switch set. Those of ordinary skill in the art call fully
understand without further description concerning the constitLltion and
operation of the suhject Pmll~lim.ont
FIGs. 3A and 3B are circuit diagrams of a switching system in
accordance with another rmho~lim~nt of the l~resent invention This
embodiment provides a switching system which can warn against
~ WO 95124759 ~! 1 8 ~ 3 J ~ C 18
emergency betwe~ll isolated l~laces. When coml~arecl with th~
embodimellt of FIG 1, this embodiment is equal to th~t of FIG.1 with
the excel~tion that the io~ld selectors ~0 included in the load controlling
units 200A ~ 200E are removed, and thereby the outl~uts from each of
5 transistors are combined and electrically connected t() the
corresl~onding l~hoto-coul~ler, and means for warning, for examl~le, a
sl~eal;er is further provided.
Therefore, if a control signal is sul~l~lied from any switch set
installed in isolated l~laces, all the loads are ~im~ ousl~ ol~erated
10 and then the load c~)ntrolling units 200A~200E disl~lay a corresl~ondin~
l~osition through LED. Accordingly, a warning against the l~lace
where a state of emergency occurs is given.
FIG. 4 is a circuit diagram of a switching system in accordance
with furth~r another embodiment of the llresent invention. The device
15 of FIG. 4 is coml~osed of microchil~s eml~loyed with all integrated
circuit of I~';57C501G or IiS57C240~, and l~articularly comprises a
microcoml~uter and peripheral machineries which l~rogram the basic
SPEC. The device of this embodiment designates each load as each
of different addresses (I~rol~er number), and controls it on the basis of
20 the address. That is, a resl~ective switch endows different signals,
and includes a load selector 92 in which both each load an~l switch for
controlling the load are electrically selected and connected. A remote
signal receiving l~ortion 91 receives a power control signal which is
transmitted in an infrared form from the remote controller (not shown)
25 and sul~plies the signal to the mi.lu.or~ u~ 90. In the case that ~
addresses for each of loads may be d~ n~r~rl used is a load selector
92 eml~loying an integrated circuit of ~M93C4~i. A
transmitting-receiving unit 9~, eml~loyed by an integrate~l circuit of
74HC07, receives and transmits signals between other units which are
30 similar to the device of FIG.4.
Frist and second driving controllers 94 and 94', which may

employ integratcd circuits of RA2fi51 and I~A2657 resl~ectively, drive a
LED disl~lay unit 9~ in order to disl~lay the opcration of a certain loa~l
in response to ail output signal of the microcoml~uter 90. On the
other hand, a loac~ controller 96 controls the powcr sullply to thc
5 corresponding load in response to an output signal of the
microcoml~uter 90. A second s~itching unit lOI is installed between
an output terminal of the load controller 96 and the load, in which z
tri-state mech.lnical gwitch lies so that its mechanical tyl~e mcly b~
switched ill case tllat its electronic tylle is out of order. In addition,
10 the device of FIG. 4 further comprises a button-tyl~ed first switchin~
unit 97. a confirmatory unit 98 and a load control limit unit 99.
FIG. 5A is ~ concrete circuit diagram for coml~onents of th~
embodiment of FI~, with which the ol~eration state and process of
each component~s will be further described. The microcomputer 90
15 controls th~ switching ol~eration of a switching unit 97, coml~c)se~l of a
l~lurality of switches 1--20, S)--Ss, controls so that a rem()te signal of
the remote receiving unit 91 ma~ be supl~lied to the load controller 96,
and drives transistors and coil-type relay according to the sul~l~lied
outl~ut signal, thereby making the load on or off. Also, the same
20 signal is sul~plied to the driving controllers 94 and 94' and an c~n/off
state is displayed red or green, separately.
The switchine system of FIG. 5A has the same constituti~n as
that of FIG.4, but is composed of a plurality of units, in which
tr,~ngmitting-receiving unit 93 is installed so that tbe same action such
25 as tr:~ncmisci-ln oE the same signal may be made. The switches S,--
Ss of tbe switcbin~ unit 97 are designed to control easily in th~
switch set of each room, and then the load selector 92, EEPROM for
setting an address, can be included so tbat a specific load may be
regulated by any button among each switch. Moreover, the device
30 comprises the load control limit unit 99 for limiting an on/off ol~eration
with respect to any sl~ecific load, and the confirmatory unit 98 for
Wo gs/247s9 Z 1 8~2 ~ 3 ~ 18
l~erforr~iing ALL OFF act;on and confirming a state of th~ LED
disl~lay.
The device of FIG. 5B is the same constitution and function as
that of FIG. 5A with the exception that the EEPROM for setting an
5 address is rel~laced with a DIP switch, in coml~arison with the device
of FIG. 5A, and a l~art of function is omitted ancl simplified.
Accordingly, since curtailment of manufacturing cost due to the
omission and reduction of a l~art of functions is achieved, and in the
constitution of the l~resent invention, a scheme that FIG. 5A is utilized
10 as a main control switch and FIG. 5B as a sub-control switch call be
considered. In this matter, the main control switch unit can em~ y
EEPROM and the sub-control switch unit can use the DIP switch for
the address setting of each load. In this case that the classifie~l main
control switch unit and sub-control switch unit are connected to the
15 switching system of the present invention, the main contrc)l switch
unit can l~erform all functions for turning on/off all loads connected to
the system and for monitoring their on/off states, where~s the
sub-control switch Ul~it may l~e controlled by the main control switch
unit and execute only a limited function to manil~ulate on/off states of
20 the connected loads. However, Both of them are of gre~t utility in
view of use and exl~ense.
FIG. 5C is a circuit diagram of a remocon in which a terminal of
a radio call receiver PAGER to the exterior is incorporated, which is
intended to control an on/off state of each load in the switching
25 system by phone. When the prol~er number and secret number of the
radio call receiver and the designated number of the switching system
are dialed, a signal of the tr,ln~mi~in~ unit 102 is sul~l~lied to the
remote receiving unit 91 of FIG. 5A by the ol~eration of the
microcomputer 105 and a remote control switching unit 104 through
30 exterior receiving terminal, thereby the corresl~onding load designated
by the microcoml~uter 90 is controlled to turn on/off.
