A system for monitoring a structures containing utility components is provided. The system includes a sensing devices, each being disposed within a structure and distributed within a geographic region, each of the sensing devices measuring parameters within the structure. A display is coupled to the sensing devices and is positioned remotely therefrom. One or more processors communicate with the sensing devices and the display. Wherein the processors perform a method comprising: receiving the measured parameters; comparing the measured parameters to thresholds; displaying on the display device elements, each device element representing one of the sensing devices, each of the device elements being geometrically arranged on the geographic distribution of the sensing devices; displaying on the display a plurality of elements, each associated with one of the device elements; and changing at least one of the elements when a measured parameter crossing one of the thresholds.

A well cover assembly includes a monitoring device and a well cover. The well cover includes a first protrusion and a second protrusion. A through hole is defined on the well cover and surrounded by the second protrusion. The monitoring device can be installed on the well cover. The monitoring device includes a monitoring terminal and a fixing bracket. The fixing bracket includes a first bracket and a second bracket. One end of the first bracket is fixed to the monitoring terminal, and another end can protrude from the through hole. The second bracket is connected to the end of the first bracket protruding from the through hole, the second bracket can extend from the end of the first bracket toward an edge of the second protrusion and toward the first protrusion. The second bracket further can clamp with each of the second protrusion and the first protrusion.

An access cover to underground city infrastructure, particularly a cast iron or a cast iron-concrete cover provided with a cover detection sensor connected with a radio frequency signal transmitting antenna through a transmitter, characterized in that an antenna module (1) provided with a housing made of a material neutral to electromagnetic fields, preferably made of plastic, is installed in the through channel or hole (4) with variable cross-section, and removably fixed at the bottom to a sensor module (2) located underneath the bottom of the cover (3), provided with a battery powered, low current electronic system containing a radio transmitter and an acceleration sensor or a gyroscope and an appropriate controller which detects changes to the position of cover (3) in space and in time, whereby the surface area of the sensor module (2) is greater than the surface area of the through channel or hole (4).

The object of the invention also includes a method of cover monitoring.

A utility cover for covering an opening includes an outer frame formed of a first material and an insert within the outer frame formed of a second material, wherein at least a portion of the insert is substantially transparent to wireless communications.

A tubular insert sleeve system comprises a tubular insert sleeve for insertion into an excavated hole and a snug fitting and removable safety cover adapted to extend over the upper end of the tubular insert sleeve in order to cover the excavated hole. One or more sleeve fastening apertures are defined through the tubular insert sleeve adjacent the upper end thereof, and are adapted to receive one or more vermiform fasteners for fastening the safety cover to the tubular insert sleeve. Preferably, the sleeve fastening apertures are in the form of handles. In some embodiments, one or more cover fastening apertures are defined through the safety cover and the cover fastening aperture(s) cooperate with the sleeve fastening aperture(s) to receive the vermiform fastener(s) to fasten the safety cover to the tubular insert sleeve.
