surface current measurement network using cellular Telephone Telemetry
IEEE Working Conference on Current Measurement, 1995Co-Authors: G F Chaplin, F J KellyAbstract:An array of five near-surface current measuring buoys has been designed and deployed in the Gulf of Mexico. Each buoy is networked with a central shore station via commercial cellular Telephone service. Each buoy employs an electromagnetic water flow sensor (2 meter depth) and a vector-averaging data acquisition system to collect and record near-surface current data. Buffered data are automatically transferred to a shore station on a programmed schedule using the MNP Class 10 high performance data communications protocol. Under user control, the shore station can communicate with individual buoys to modify the data collection and reporting schedule as well as recover archived data. The low-cost, small-profile, solar-powered buoy is deemed "collision survivable" by the manufacturer. The buoy can be deployed from a surface vessel or helicopter.

streamflow gaging in a remote area using cellular Telephone Telemetry
Waterpower '91: A New View of Hydro Resources, 1991Co-Authors: David C Wheelock, Rhett C HurlessAbstract:A case study will be presented describing the utilization of cellular phone technology in a remote sensing situation. Because expected annual energy estimates are vital in planning small hydroelectric projects, it is important that the flow data from river gaging stations provide reliable information to the engineer. When the project is situated in a remote area where gaging stations are unavailable, such as on an island or in emerging nations, the design engineer may need to provide the flow data himself. The problem of transmitting the flow data from a remote mountain stream away from any roads and Telephone lines, to the office for computer analysis was solved by using an innovative method utilizing cellular Telephones to access raw data from solar powered data loggers and pressure transducer gaging instruments. This paper will detail how the technical and practical problems were addressed, making the system viable and potentially suitable for other remote locations. Methods used by the team to cope with the isolated environment in accumulating reliable flow data will also be discussed.

Using cellular Telephones for data collection
1993Co-Authors: R.c. HurlessAbstract:Collecting and monitoring large amounts of data is a [open quotes]way of life[close quotes] for many hydroelectric project developers and operators. For example, one of the first tasks for a developer of a proposed hydroelectric site is to collect river flow data for estimating annual energy production. And, once a project is operating, the owner must project is operating, the owner must collect numerous data for monitoring instream flow, reservoir levels, outflow, and dam stability. It is not unusual for data collection sites-such as project intakes-to be quite remote, miles away from roads or Telephone lines. In these cases, collecting the data and getting it to a central office for analysis and/or monitoring can pose logistical problems. One option is using a cellular Telephone for data collection and transmission. As cellular phone technology improves and more people begin using the equipment, companies are beginning to expand their service areas. These areas are now likely to include many remote hydro sites. The option of using cellular Telephone Telemetry to obtain needed data from a remote site is readily available and relatively inexpensive. However, in establishing such a system, the user may encounter numerous problems. When engineers from Synergics, Inc., a privatemore » hydro developer, installed a cellular phone data collection system, they experienced several complications. A review of this installation provides tips that would enhance the effectiveness of such a system.« less
