DETAILED DESCRIPTION
Referring to the drawing and FIG. 1 in particular, shown therein and
generally designated by the reference character 10 is a security system in
accordance with one embodiment of the invention. As illustrated, the
security system 10 comprises the individual unit system 12 installed in or
on the individual or predetermined unit 14 which is to be monitored for
security and hazard purposes. The individual or predetermined unit 14
would comprise a boat, recreational vehicle, trailer, automobile,
apartment, mini-warehouse, etc. The individual unit system 12 comprises a
plurality of sensor means 16, a receiver means 18 and a slave transmitter
20. Each sensor means 16 includes a detector 22, a digital encoder 24, a
transmitter 26 and a radiating unit or antenna 28. Sensor means 16 are
structured and positioned in the individual or predetermined units 14 to
detect and signal abnormal or emergency conditions, such as unauthorized
intrusion; the presence of fire, smoke, gas, carbon monoxide; glass
breakage; opening of doors or windows; unauthorized moving of the unit;
removal of structure from the outside of the unit; low battery voltage;
high water level in the bilge and other well known type of detectors. For
instance, the opening of doors or windows and the removal of structure
could be detected by the use of magnetic switches. The digital encoder 24
provides for the setting of a digital code for each sensor means 16 which
allows identification of each individual unit 14 and each sensor means 16
associated with that individual unit 14. In the preferred embodiment, the
digital code comprises eight bits to identify the individual unit 14 and
four bits to identify the individual sensor means 16, e.g., magnetic
switch, pressure mat, glass breakage, fire, smoke, motion, current, high
water, etc. In the preferred embodiment, the selection of the code
function is provided by DIP switches. The transmitter 26 would be (1) the
rf type in the frequency range and power as approved by the FCC, (2)
infrared type, (3) ultrasonic type, etc. which would transmit the coded
signal through the atmosphere rather than over cable or land line.
Each receiver means 18 comprises a receiver 30 and digital encoder means
32. The digital encoder means 32 provides for the setting of an eight bit
digital code to identify the individual or predetermined unit 14 with
which the receiver means 18 is associated and only allows reception of the
coded signals from the sensor means 16 for the associated individual or
predetermined unit. The eight bit digital code of the receiver means 18
must match the eight bit digital code of each of the sensor means 16 for
the associated-individual or predetermined unit. In the preferred
embodiment, the selection of the eight bit digital code is provided by DIP
switches.
A key pad 34, which is part of the key pad and display unit 35, is
operatively coupled to each receiver means 18. Key pad 34 allows the owner
or operator of the security system 10 to configure the system to his
particular wants or needs. Security system 10 has delay times built into
the system which allows the owner or operator a set amount of time to
leave the unit 14 before the security system 10 is activated or armed and
a set time to enter the unit 14 and deactivate or disarm the security
system 10 before it is triggered by his intrusion. The sensor means 16 are
grouped into groups 30 which can be controlled, to a degree, from the key
pad 34. The groupings are (1) the security sensors, e.g. pressure mat,
glass breakage, the opening of windows or doors, motion detector, etc.,
(2) the hazard sensors, e.g. LP gas, fire, smoke, carbon monoxide, low
battery, high water in bilge, etc. and (3) the infrared motion detector.
Groups (1) and (3) can be activated and/or deactivated together as one
group from the key pad 34. Group (2) can be activated and/or deactivated
as a separate group. After groups (1) and (3) have been activated, group
(3) can be deactivated, leaving group (1) activated. So, basically, key
pad 34 allows the operator to control and configure the system.
An alarm device 36 is operatively connected to receiver means 18 to receive
an activating signal when receiver means 18 receives a proper and
recognized transmitted coded signal from a sensor means 16 associated with
the individual or predetermined unit 14 with which the receiver means 18
is associated as part of the security system 10.
Detector 38 is operatively connected to the housing of receiver means 18 to
activate the security system 10 if an intruder attempts to obtain access
to the receiver means 18 and deactivate the security system 10 before it
is activated by the intruder's entry into the individual or predetermined
unit 14. In the preferred embodiment, detector 38 comprises a magnetic
switch.
Panic switch 40 is a wireless transmitter similar to transmitter 26 which
transmits a coded signal through the atmosphere to receiver means 18 when
activated. The panic switch 40 is portable and is activated to trigger the
security system 10 if the owner or occupant of the unit desires to trigger
the alarm to signal for help if they are ill, have fallen, hear someone
attempting to break into the individual or predetermined unit 14.
A display unit 42, which is part of the key pad and display unit 35, is
operatively coupled to receiver means 18 to display a code designating
which sensor has been activated.
A coded signal output is sent to the slave transmitter 20 via cable 44 and
activates the slave transmitter 20 to transmit a coded signal through the
atmosphere. The slave transmitter 20 includes encoder means 46 for setting
a twelve bit digital code which identifies the particular individual or
predetermined unit where the slave transmitter 20 is located. In the
preferred embodiment, the selection of the twelve bit digital code is
provided by DIP switches. In the operation of the individual unit system
12 when a sensor means 16 is activated or triggered, sensor means 16
transmits the twelve bit coded signal through the atmosphere to receiver
means 18. Receiver means 18 checks the eight bits of the coded signal to
determine if the received signal is from a sensor means associated with
the same individual or predetermined unit 14 with which the receiver means
18 is associated. If the received signal is from a sensor means 16 which
is on the same individual unit 14 as the receiver means 18, receiver means
18 will check to determine if the individual unit system 12 is activated
or not. If the individual unit system 12 is activated then receiver means
18 will cause the code, for the particular sensor means 16 which has been
triggered, to appear on display unit 42. Receiver means 18 then sends the
four bits of data, which designates the type of sensor means 16 which has
been activated, on to the slave transmitter 20. If the individual unit
system 12 is not activated, nothing additional happens. Slave transmitter
20 adds twelve digital bits, which designates the particular individual
unit 14 where the individual unit system 12, which has triggered, is
located and transmits the sixteen bit coded signal through the atmosphere.
With further reference to the drawing and to FIG. 2 in particular, shown
therein and generally designated by the reference character 50 is a
security system in accordance with an additional embodiment of this
invention. As illustrated, the security system 50 is directed to a
security system for a given or designated security area 52 which includes
a plurality of individual or predetermined units 14. Security system 50
comprises a plurality of individual unit systems 12 installed in and
around each individual or predetermined unit 14 and a local security
station 54. It will be appreciated that the local security station 54 may
be within or outside the given or designated security area 52.
With reference to FIG. 3, the local security station 54 is shown and
comprises a station receiver 56 whose output is provided to interface
circuitry 58 whose output is provided to the master control unit 60.
Master control unit 60 provides an output to printer 62, an output to
alarm 64 and an output and input line 66 which is connected to the
telephone line jack of the telephone line to the telephone company or to a
cellular telephone. A touch-tone telephone 68 provides an input to the
master Control unit 60 and receives an input from the speech synthesizer
78 in the master control unit 60.
With reference to FIG. 4, the master control unit 60 is shown and comprises
a CPU 70 operatively connected to memory 72 and providing an output to
display 74. DTMF signal detector 76, speech synthesizer 78 and auto dialer
80 are connected in parallel between CPU 70 and DAA 82. DAA 82 is
connected to the telephone line from the telephone company. Memory 72
includes the program instructions for CPU 70 to perform the various tasks
required as well as the messages to be transmitted by the speech
synthesizer 78 and the telephone numbers to be dialed by auto dialer 80.
In the operation of the security system 50, the individual unit systems 12
operate as previously discussed. When a slave transmitter 20 transmits the
sixteen bit coded signal through the atmosphere, it is received by antenna
28 and output to station receiver 56 whose output is provided through
interface circuitry 58 to the master control unit 160. The master control
unit 60 checks to make certain it is on and if it is on the master control
unit 60 will provide an activating signal to the alarm 64 located at the
local security station 54 and sound alarm 64. If there is personnel in the
local security station 54, they have a predetermined time, e.g. three
minutes, in which to pick up the touch-tone telephone 68 and dial a
predetermined intercept code which goes to the CPU 70 and cancels the
alarm sequence. If there is not any personnel in the local security
station 54, the master control unit 60 will start the sequence of dialing
three telephone numbers, which have been placed in memory in the master
control unit 60. At the same time, the CPU 70 will output information to
the display unit 74 and the printer 62 which will include (1) the time,
(2) the date, (3) the individual unit identification where the alarm
occurred and (4) the type of alarm. The three telephone numbers could
include the police, an independent security business, the owner of the
designated security area, a beeper number, the home of an individual, etc.
The three telephone numbers will be sequentially dialed until someone
answers one of the dialed phones. When one of the dialed phones is
answered, the person who answers the phone must dial in a predetermined
sequence of numbers. The master control unit 60 then knows that someone
has acknowledged the receipt of the alarm notification and the speech
synthesizer outputs a message informing the individual on the phone of the
details regarding the alarm. These details will include (1) the time of
the alarm, (2) the date of the alarm, (3) the individual unit
identification where the alarm occurred and (4) the type of alarm. When
one of the three dialed phones has been answered, the printer will print
out an acknowledgment message which will include (1) the time the alarm
was acknowledged, (2) the date the alarm was acknowledged and (3) the
party who acknowledged the notification of the alarm by the sequence of
numbers dialed by the party.
Another feature of the security system 50 is that the master control unit
60 is programmable from any touch-tone phone. Normally the individual unit
systems 12, with the exception of the slave transmitter 20, are sold to be
installed in the individual or predetermined units 14. The company which
manufactures the security system 50 leases the slave transmitter 20 to the
owner of the designated security area 52 where the individual or
predetermined units 14 are stored or housed, who in turn sub-leases the
slave transmitter 20 to the owners of the individual or predetermined
units 14. Each month the company is to collect a set amount for each slave
transmitter 20 leased to the owner of the designated security area 52. If
for any month, the company does not receive a check from the owner of the
designated security area 52, the security system 50 goes into a programmed
ten day grace period in which it will continue to operate. After the ten
day grace period, the master control unit 60 of the security system 50
will shut down in accordance with a predetermined program placed in memory
72. When a check is received, a predetermined code will be sent over the
telephone to the master control unit 60 which will update the master
control unit 60 and allow it to operate for another month.
Thus, it is apparent that there has been provided in accordance with this
invention, a security system for monitoring a plurality of individual
units from a centralized location.
Although the present invention has been described with reference to a
presently preferred embodiment, it will be appreciated by those skilled in
the art that various modifications, alternatives, variations, etc., may be
made without departing from the spirit and scope of the invention as
defined in the appended claims.
