REMOTE MONITORING AND CONTROL SYSTEM
The present invention relates to a remote monitoring and control system. More particularly the present invention relates to the remote monitoring of environmental conditions and the status of appliances within premises, and additionally the remote control of condition adjustment apparatus and the remote control of operations of appliances within the premises. In this context 'remote' has the meaning of 'external to the premises'.
There are a number of well known means by which it is possible to effect communication between people and appliances within premises, using devices which use electrical signals, radio waves or infra red light beams. For example, the control of domestic lighting, heating and appliances by signals superimposed on the electrical power wiring of the premises, the control of a television receiver by hand held infra red beam transmitter. Similarly the monitoring of conditions within premises for example, temperature, humidity, movement detection by infra-
red radiation monitoring, sound monitoring for baby alarms and intruder detection are well known. However these systems have drawbacks of either requiring electrical connection between apparatus, which is time consuming and therefore expensive or are confined to be within the premises or, using wireless interconnection by light / infra red, communication is line of sight only or the use of radio frequencies hitherto requires licensing of radio transmissions.
Also existing monitoring and control systems within premises do not provide a means of comprehensively controlling apparatus and monitoring the status of apparatus and monitoring environmental conditions within the premises, in real time, by a device external to the premises. It is the object of this invention to achieve such comprehensive monitoring and control using (for example) a hand held portable cellular telephone external to the premises.
According to the present invention there is provided distributed monitoring and control apparatus situate within premises said apparatus being characterised as having means of communication for operating cooperably between them without interconnecting wiring, said apparatus being further characterized as having both individually and co-operably one or more means of monitoring and control, said means being activated and deactivated in response to
communication with one or more devices situate external to the premises, said apparatus situate within premises being further characterized by using radio frequency signals for communication of audio and digital data between them, said radio frequency communication being further characterized by not being required to be licensed transmissions.
The benefits of this invention are that the monitoring and control apparatus within the premises does not require wired interconnections and therefore needs only unskilled installation. Also the owner of the premises can independently, at any time, monitor' for example, the security of his premises, listen to sounds within the premises, view the interior of his premises in real time, activate or deactivate the heating system; using, for example, his cellular telephone from any location.
A preferred non-limiting embodiment of the present invention will now be described by way of example and with reference to the accompanying drawing.
Figure 1 - shows in block diagram form the arrangement of an apparatus designated 'master' and one or more apparatus designated Slave' and their internal organization.
The slave apparatus [2] requires d.c. electric power to function. It obtains its electric power by direct connection to the a.c electric utility supply and then via power conversion to d.c. also from an internal battery [3] providing d.c. power in the event of ac power supply interruption.
The slave apparatus [2] contains means [4,6,8] of undertaking the real time measurement of one or more physical parameters using one or more associated sensor device(s) [5,7,9] said devices being internally incorporated within or attached to the apparatus. Said measurements are converted to digital signals in a form suitable for transmission between apparatus by radio communications. The physical parameters sensed are, for example without limitation, temperature, humidity, light illumination level, noxious gas concentration.
The slave apparatus [2] additionally contains means [ 10,12,14] of undertaking the real time reception and processing of one or more signals characterized by their frequency spectra. For each such signal there is an associated, receiving device [1 1,13,15], which is internally incorporated within or attached to the apparatus. Said signals are converted to digital signals in
a form suitable for transmission between apparatus by radio communications. The signals received are, for example without limitation, sound waves, electromagnetic waves in the visible spectrum, electromagnetic waves in the infra red spectrum.
The slave apparatus [2ladditionally contains one or more means [ 16, l 7] for generating electrical signals which can be used either directly or via isolating devices for the purpose of controlling the activities of external apparatus, such apparatus for example without limitation I being washing machine, television, lighting unit, heating appliance, motor. One or more said controlling signals can occur separably or co-operably to provide simple on / off control functions or more complex control sequences.
The slave apparatus [2] additionally contains means [18] of initiating, ceasing and controlling the operations of measurement, signal processing and / or communication as hereinbefore described, said means [ 183 being caused to act either independently or as a result of data received by communications from the master apparatus or from another slave apparatus. A preferred embodiment of said means of operational control [ 18] is by computer program stored in semiconductor memory causing electrical control signals to be stimulated by a semiconductor microprocessor device.
The slave apparatus [2]additionally contains means [19] for the modulation and demodulation of radio frequency carrier signals to provide for reception and transmission of signals at radio frequencies This two way communication link is used by the slave apparatus to receive and send data to the master apparatus or to another slave apparatus. The frequencies involved do not require licensing.
Each of the said means [4 to 17] within a slave apparatus as hereinbefore described is assigned a unique identification code. Embodiments of slave apparatus may include one, any subset or all or more of the means [4 to 17] hereinbefore described.
The master apparatus [20] contains means of communication l2 1] by transmission and reception of radio frequencies in order to provide two way communication between master apparatus and slave apparatus.
The master apparatus [20] additionally contains well known means of communication [22] by transmission and reception of radio frequencies in order to provide two way communication between the master apparatus and an external apparatus [11. This external apparatus [1] will often be a hand held cellular telephone but could be any apparatus which employs similar communications technology. The master apparatus will be assigned a unique address consistent with present addressing conventions of cellular telephone systems.
The master apparatus [201 additionally contains means [23] of initiating, ceasing and controlling the operations of communication with external apparatus and with slave apparatus as hereinbefore described. A preferred embodiment of said means of operational control [23] is by computer program stored in semiconductor memory causing electrical control signals to be stimulated by a microprocessor device.
Similar to the slave apparatus [2] the master apparatus [201 requires d.c. electric power to function and obtains its electric power by direct connection to the a.c electric utility supply and then via power conversion [24] to d.c. also from an internal battery [25] providing d.c. power in the event of ac power supply interruption.
The sequence of activities of the master and slave apparatus can be described as a response to a communication received from said external apparatus [l].
Said communication from said external apparatus can take a number of forms, for example, a text message or key strokes or voice commands the latter two giving instant real time acknowledgement of the command. The command can be both command codes and data (if necessary) according to a format which thereby defines one or more actions to be undertaken by one of the means [4 to 171 included in a slave apparatus [2].
This message is received by the master apparatus via known cellular communications technology. The master apparatus broadcasts, the unique identification code plus command code and data to cause the slave apparatus [2] to undertake a task as hereinafter described. 2 Examples, without limitation, of tasks are:
The slave apparatus undertakes a measurement process on one of the physical parameters corresponding to a unique identification code by performing analogue to digital conversion of the electrical signal produced by its associated sensing device and storing the resulting digital representation of the measurement value in semiconductor memory. The said measured value is transmitted to the master apparatus which in turn transmits the information to the external apparatus. Similarly the slave apparatus undertakes an analogue to digital conversion process on the signals produced by each receiving device to give a digital data stream representing the signal variations in real time. This digital data stream is modulated onto a radio frequency and transmitted to the master apparatus which in turn transmits the said data stream to the external apparatus. The slave apparatus generates an electrical signal used to initiate or cease the operation of an associated appliance.
