1. Field of the Invention
The present invention relates generally to a remote monitoring system and more specifically it relates to a remote pipe lining air monitoring system for remotely monitoring air pressure when curing a pipe liner.
2. Description of the Related Art
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
Cured-in-place pipe (CIPP) liners have been used for many years for the rehabilitation of different types and sizes of conduit and piping systems such as utility, sewer, water, electric, telecom, industrial, petroleum, fire suppression, heating, cooling and the like. CIPP requires the liner to be expanded and cured using hot water, ambient air, steam or UV lights. When using ambient air pressure to expand and cure a pipe or conduit liner, it may require leaving the expanded liner for long periods of time before the thermosetting resin impregnated liner cures. This requires someone to constantly watch and monitor the air pressure so that the liner doesn't deflate and lose its shape. If the liner loses pressure and then cures, it would require cutting the liner out of the pipe or conduit. This would take a considerable amount of time and expense, it may also damage the existing pipe or conduit, therefore a constant monitoring is required to make sure the pressure is maintained.
There are air compressor systems and regulators that will provide a constant supply of air to the liner when utilizing ambient air curing, but these systems are not always reliable. Electrical failure may occur to the compressor as well as other mechanical failures may happen.
It is the intent of this invention to monitor the air pressure required to cure a cured-in-place-pipe or conduit liner without the need of having someone, such as a lining technician, to constantly be present during the ambient air pressure curing process of the liner. It is also the intent of this invention to remotely alert the technician if air pressure drops or increases inside of the curing liner. It is also the intent of this invention to allow the technician to remotely view the monitoring gauges at any given time during the curing of the liner.
Because of the inherent problems with the related art, there is a need for a new and improved remote pipe lining air monitoring system for remotely monitoring air pressure when curing a pipe liner.
The invention generally relates to a remote pipe lining monitoring system which includes a case storing an internal monitoring system. The case includes a port which is adapted to be fluidly connected in-line between an air compressor and a pipe liner. An internal compartment of the case includes the various components of the monitoring system, including a communications device, illumination device, air pressure monitor, alarm device, and a camera. The illumination device illuminates the internal compartment of the case while the camera is directed at the air pressure monitor. The communications device remotely transmits a video signal of the monitor to a remote device. In the event of pressure change or loss of power, the audio detector will detect activation of the alarm device and cause an alert to be transmitted to a remote device by the communications device.

The illumination device 52 is powered on and preferably left illuminated so that the internal compartment 24 of the case 20 is illuminated even when closed.
Any necessary configuration or set up of the air pressure monitor 54, alarm device 56 and camera 58 may be undertaken at this point. The air pressure monitor 54 should be tested to ensure proper operation. The camera 58 will be activated with its lens 59 pointing directly at the air pressure monitor 54. The air compressor 12 may then be turned on to initiate the pipe lining process. The air compressor will direct air pressure through the pipe liner 14.
Preferably, the air pressure monitor 54 will initially be viewed to ensure proper operation. The alarm device 56 may be tested by disconnecting power during operation to ensure that an alarm is properly initiated upon loss of power. Further initial testing may be undertaken by disconnecting the port 40 or powering off the air compressor 12 to ensure that an alarm is initiated upon loss of pressure. The case 20 may then be closed by securing the cover 22 to the base 20. The present invention may then be left to operate, with the operator free to travel to any remote location.
During operation of the lining process, the present invention will continuously monitor the pressure and power to ensure proper functionality.
Using this functionality, a technician may periodically check up on operation of the present invention to ensure that no alerts were missed and that everything is functioning properly. It should be appreciated that the camera 58 may, in some embodiments, be adapted to continuously transmit such images at all times that the present invention is active. In other embodiments, the camera 58 will only transmit such images upon request by the technician, such as via the remote device 18. The latter configuration may aid in reduction of power consumption by the present invention.
The alarm device 56 will activate and emit an audible alarm to indicate that power has been lost. The audio detector 57 of the present invention will detect the audible alarm. The communications device 50 may then activate to transmit an alert to the remote device 18 that the power has been lost. As previously mentioned, the alert may comprise various forms of communication, including text messages, phone calls, emails, instant messages, and the like. Upon receipt of the alert, the technician will be notified of the conditions so that any problems may be addressed.
The alarm device 56 will activate and emit an audible alarm to indicate an unexpected change in pressure detected by the air pressure monitor 54. The alarm emitted due to loss of pressure may be distinct from that which is emitted due to loss of power so that the audio detector 57 can distinguish between the two conditions. In other embodiments, the audio detector 57 may utilize other methods to distinguish between the conditions. In some embodiments, separate audio devices 56 may be utilized for the power source 30 and the air pressure monitor 54, respectively, such that different audio devices 56 are being activated for each condition.
Upon detection of the audible alarm by the audio detector 57, the communications device 50 will activate to transmit an alert to the remote device 18 that the pressure has changed. Any type of alert may be initiated, such as those which have been previously outlined herein. In response to the alert, the technician will be given the opportunity to quickly address the situation without having to constantly monitor the lining process on-site.
