<br />5. SCHEMATICS provides for a graphical display of the relative locations <br />of monitoring stations along with the most recent data for each <br />station. Figure 11 represents the lower reaches of the Division 3 <br />monitoring network. <br /> <br />6. DIAGNOSTICS provides a detailed daily summary of the operating <br />characteristics for a network of stations. This includes such things <br />as missed transmissions, parity errors, missing data values, remote <br />battery power, transmission power, and data base quality flags. <br /> <br />Additional programs have been developed internally to supplement the <br />Hydromet software. SMSEQPT provides for a computerized inventory and tracking <br />system for the remote data collection hardware, primarily 166 DCP's and 166 <br />shaft encoders with a replacement cost of $650,000.00. RECORD was developed <br />to facilitate the development of the hydrologic records. It modifies the <br />Hydromet records development programs to better meet the needs and require- <br />ments of the Division of Water Resources. Data editing can be performed on <br />either the 15-minute resolution data or the mean daily values, Editing is <br />done on a separate working file duplicated from the original data base. In <br />this fashion, the integrity of the real-time data is maintained. This is <br />necessary since administrative decisions are based on the evaluation of <br />real-time data. LOG was developed to monitor transmission activity on a <br />specified demodulator. This includes scheduled and unscheduled transmissions <br />making it possible to identify unauthorized transmissions that could cause <br />interference problems. <br /> <br />D. System Capabilities <br /> <br />The ability to collect data remotely on a real-time basis is the most <br />fundamental capability of the system. The latest data values are never more <br />than four hours old. Random (emergency) transmissions update the data base at <br />intervals down to two minutes if user defined thresholds at the remote site <br />are surpassed, The remote data collection hardware is easily installed and <br />can be operated in remote locations utilizing portable power packs and solar <br />panels. The hardware can be operated in a wide environmental range from -40'C <br />to +55'C. The DCP's are user programmable in the field. The units are <br />capable of interfacing with up to 16 sensors simultaneously in either analog <br />or digital mode. Very few locations in Colorado do not have a line-of-sight <br />with either GOES-CENTRAL or GOES-WEST. As the GOES spacecraft are in a <br />geostationary orbit, continuous communications can be maintained. The Direct <br />Readout Ground Station can operate in an urban environment with negligible <br />radio frequency interference. The receive site is equipped with eight demodu- <br />lators allowing the monitoring of eight GOES channels simultaneously. All <br />transmissions through GOES are in the public domain. The state's receive site <br />is thus capable of monitoring all transmissions of interest through either <br />GOES-CENTRAL or GOES-WEST. The system is capable of handling a minimum of 350 <br />DCP's. Data storage capacity is 912 MBytes. Up to 32 users can access the <br />system simultaneously. The system evaluates incoming transmissions and <br />prepare a detailed summary of pertinent operating characteristics. <br /> <br />-18- <br />
