ABSTRACT

During the construction of buildings and tunnels, inclinometer probes are used to measure lateral movements in bore-holes at various locations along the retaining wall. Each inclinometer measurement can take up to 60 minutes per bore-hole. The measured raw data is logged in a portable readout unit. The worker moves and measures at various bore-holes. At the end of the day, the readout box is brought back to an office computer for downloading the stored data. The raw data is processed into lateral movement readings for the engineer to analyze and check. If there is no reading error or unexpected movement, the inclinometer measurement report is submitted to the client. However, if the inclinometer measurements show unexpected large movements, the engineer has to re-measure that bore-hole reading before raising an alarm. This re-measurement can cause a critical time delay for decision making for remedial action and this information is not shared with any other stake holders. With a re-measurement, the inclinometer results will be known only on the following day. This traditional method hinders rapid remedial action. Such method of processing raw data can be subjected to reading alterations. Using Machine to Machine (M2M) Technologies into the inclinometer measurements, this innovative method of data transmission can achieve:

(a)The bore-hole inclinometer measurement from any remote sites can be downloaded without the need of an on-site computer.
(b) The processed information is available to users within 10 minutes, anywhere in the world, via email.
(c) The measured data is time stamped at every stage to automatic track its information flow.
(d) If there is a re-measurement is required, the office engineer can immediately contact the site staff for a re-measure that bore-hole. This will increase man power efficiency and reducing the time.
