TITLE: Monitoring system DESCRIPTION
This invention concerns monitoring systems, particularly but not exclusively for use by utility services.
Utility meters, such as for water, gas and electricity supplies have to be read directly periodically in order to assess charges. However, if access to a meter is not possible when the meter reader calls, an estimated charge is made, which can lead to incorrect charging, if the meter is not read for sometime. It would, therefore, be advantageous to read such meters remotely.
An object of this invention is to provide an improved remote monitoring system, which may be used for remote monitoring of utility service meters.
According to a first aspect of the present invention there is provided a remote monitoring system comprising a signal emitter providing a signal, means for transmitting the signal via a telecommunications system and remote means for receiving the transmitted signal.
The signal may be transmitted in any desired format, such as, as data or an image in digital form.
As well as transmitting signals, the system may further comprise means for receiving a signal from a remote source for activating the system.
Signal transmission to and from the remote monitoring system may be by way of a fixed telecommunications transmission line or by way of a global specification for mobile telephones (GSM) network.
The monitoring system of the invention may be used to read utility meters, wherein the signal emitter is a utility meter, such as an electricity supply meter, a gas supply meter or a water supply meter. For convenience, the meter dial can be viewed by a camera and the reading transmitted to a remote receiver.
According to a second aspect of the present invention there is provided an improved monitoring system, especially for utility meters, comprising a hood for covering a meter register, the hood containing a camera for recording a reading on the meter register as an image, means for transmitting the recorded image to a remote receiver and power supply means for driving the monitoring system.
The hood preferably is transparent or has a transparent section, whereby the meter register can be read normally.
The camera is preferably a digital camera. The monitoring system of the invention preferably further comprises means for processing the recorded image into a format whereby it can be transmitted to the remote receiver.
The means for transmitting the recorded image of the meter register is preferably a radio transmitter.
Power supply for monitoring systems of the invention is preferably provided by a rechargeable battery mounted in the or a hood over the meter or the meter register. The battery is preferably charged by a transformer that takes advantage of electromagnetic field energy to induce a power source for the battery. The
electromagnetic field may be conveniently provided by mains supply cable for the
meter. Preferably the transformer is a double wound transformer located around the mains supply cable and preferably within the hood.
Preferably included within the hood is a light source for illuminating the meter register for facilitating the capturing of an image of the register by the camera. The light source may be a light emitting diode.
Monitoring systems of the invention are preferably programmed to record an image of the meter register and to transmit the recorded image to the remote receiver at predetermined intervals.
Monitoring systems of the invention preferably further comprise at a remote location a modem for receiving the transmitted signal and a computer programmed to store the signal received and optionally to instigate a response thereto.
The computer is preferably programmed to interrogate the signal emitter remotely randomly or at predetermined intervals.
The signal transmitting means preferably has battery power back-up, which may be the above-mentioned rechargeable battery power supply. Operation of the battery power back-up preferably activates a signal transmission to the transmitted signal receiving means. Preferably, the monitoring system of the invention has means for sending a message to a designated receiver upon receipt of said battery power back-up signal. The designated receiver may be a telephone and the message may be a pre- recorded voice message.
In a preferred embodiment of the invention, a utility meter with a display giving a reading as a numerical value has a camera arranged to capture the image
of the display, preferably enclosed in a sealed box to avoid tampering. The camera may be a video camera and image recognition software may be used for determining the numerical display for entry into an appropriate account record.
Alternatively, a digital camera may be used to record the numerical display digitally and the digital data used to enter the appropriate numerical value displayed in the appropriate account record.
Data transfer from the camera to a central computer is preferably via a telephone dialler connected to a fixed telephone line. The system of the invention may be programmed for timed meter reading and/or for on demand meter reading.
Signals from any utilities meter may be monitored using the monitoring system of the invention. The system of the invention is believed to be particularly suitable for electricity and gas meters but may also be used in some cases with water meters.
This invention will now be further described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 shows schematically a utility meter reading system according to the invention; and Figure 2 shows a hood for a utility meter for use with the system of Figure 1.
Referring to Figure 1 of the accompanying drawings, a utility meter 10 has a numerical display 11 and a camera 12 arranged to capture the numerical display as an image in a form suitable for transmission down a telephone line. The camera is connected to a telephone dialler 14 and the captured image can be transmitted down the telephone line 16 to a computer 18 via a modem 20. The
computer is programmed to connect the numerical display image into a format that can be entered into the appropriate account record.
The output from the camera provides a signal corresponding to the numerical value of the utility meter enabling that value to be recorded against the account relative to that meter.
The system can be arranged for the either or both of timer-controlled operation from the meter end of the system and the central computer end of the system. In that way, the reading of the utility meter can be independent of the owner of the premises where the meter is situated and independent of visiting meter readers. The need for estimated billings for utilities can, therefore, be eliminated. Accurate billing for utilities is an advantage to both provider and consumer. The provision of remote meter reading eriables the utility supplier to instantly read any meter on demand. The meter reading can be performed in two ways, namely by image capture or by extracting the information from the IR port on the meter front panel. This could be taken a stage further by providing the utility supplier with the facility of either shutting down or altering the tariff of the supply, which often requires a site visit from an engineer to alter via the IR port.
All standard status transfers, including sending remote control information to the domestic base, will use the telephone line with any image information meter reading being sent by data format.
Turning to figure 2 of the drawings, the utility meter 10 is enclosed in a transparent plastics hood 22. This allows normal manual meter inspection to take
place. Inside the hood 22 is a double wound transformer 24 located around main electricity power supply cable 26 for the meter. This transformer takes advantage of the electromagnetic field created by the power cable to induce a small electrical
charge, which is fed to a rechargeable battery 28 located within the hood. The battery can hold sufficient charge to drive the meter reading system approximately every six hours.
Also in the hood is a light emitting diode (not shown) located at the register in order to illuminate the register for a digital camera in the hood to capture the image of the meter reading. The data from the register is then processed and transmitted to either a telecommunications landline or a GSM connection by means of a radio transmitter located within the hood.
