HYDROLOGICAL SERVICES 1.Introduction The Hydrological Services Rain and River Data Logger RRDL-3 has been designed using surface mount technology to provide a very small, low power and reliable data logger that can be used in harsh environments for extended periods.
HYDROLOGICAL SERVICES 2.Product Overview 2.1 Overview The Hydrological Services Rain and River Data Logger unit (shown right as a black box) is easily installed within a standard Tipping Bucket Rain Gauge, (TBRG). Rain falling on the collecting funnel is directed through a siphon control unit and discharges as a steady stream into a two compartment bucket mounted in unstable equilibrium. As each compartment fills, the bucket tilts alternately about its axis.

HYDROLOGICAL SERVICES 3.2 Setup and Configuring the Logger Once the RRDL-3 logger has been connected to a computer, the parameters can be setup using a ‘dumb’ terminal emulation program. The program should be set for the appropriate baud rate, parity and handshake, the same as the logger Dip Sw settings, as well as for "local echo on". On receipt of individual commands from the computer, the logger will respond with the current parameter setting.
HYDROLOGICAL SERVICES of the specific TBRG used as well as the number of tips that defines one rainfall event - this determines the resolution and the rate at which flash memory is used. See section 4.1.10. for more information on these commands. Three separate "Rainfall Alarms" (RAL1, RAL2, RAL3) may be programmed in a logger that has a communication path to a computer.
HYDROLOGICAL SERVICES is powered before a measurement is made. The "River Increment" (RVI) parameter defines the river height recording increment resolution expressed in millimetres. The "River Height Reference" (RVHR) is an offset that is added to the river height as measured by the transducer alone. See section 4.1.12. for more information on these commands. Three separate "River Alarms" (RVAL1, RVAL2, RVAL3) may be programmed in a logger that has a communication path to a computer.
HYDROLOGICAL SERVICES 4. Operation 4.1 Commands / Syntax Each of the logger commands that follow are described in detail and include the exact On-line Help information that is provided in the RRDL-3 logger by entering Comnd? 5 4.1.1 On-line Help (?) A list of all logger commands and abbreviated syntax is given when ?5 is sent to the logger.
HYDROLOGICAL SERVICES 4.1.2 Alarms (AL, CLA, DUA, RALx, RVALx) Alarm messages are generated when rainfall and river height conditions meet user defined alarm criteria. An alarm will cause the following sequence of events to occur:1. 2. 3. 4. 5. 6. An alarm message is constructed at the time of the alarm and saved. A CLEAR sequence is performed to get the modem into a known state. A CALL sequence is performed to cause the modem to dial a phone number.
HYDROLOGICAL SERVICES Rainfall Alarm 1 (Ral1) Rainfall Alarm 1 is a simple threshold type alarm. Once conditions meet the alarm criterion for RAl1, ( Rainfall since 0900 greater than RAl1 value) the alarm sequence is generated sending the rainfall message and the alarm condition is reset until 0900 the following day. The alarm condition can only occur once within a 24 hour period between 0900 and 0900 unless the alarm threshold for RAl1 has been re-defined by user command.
HYDROLOGICAL SERVICES Rainfall Alarm 2 and Rainfall Alarm 3 (RAl2 & RAl3) Rainfall Alarm 2 and 3 are rate of increase alarms. Alarm conditions for RAl2 and RAl3 are checked after each rainfall event against the user defined criteria for rainfall amounts over some time interval. Once conditions are satisfied, an alarm sequence is generated sending the rainfall message.
HYDROLOGICAL SERVICES River Alarm 1 and River Alarm 2 (RvAl1 & RvAl2) River Alarms 1 and 2 are threshold type alarms. When the river height rises to a level as defined by RvAl1 or RvAl2, an alarm sequence is generated sending the river message. Successive alarms of the same type can only occur if the river height falls below the defined threshold of RvAl1 or RvAl2 and rises again to satisfy the alarm criteria or if the criteria are re-defined by user command.
HYDROLOGICAL SERVICES River Alarm 3 (RvAl3) River Alarm 3 is a rate of change alarm. Alarm checking for RvAl3 will commence once the river rises above a user defined threshold. Above this threshold an absolute change in river height over a defined time interval as specified by RvAl3 interval parameter, will trigger an RvAl3 event. Alarm checking for an RvAl3 condition is then disabled for a period of time equivalent to half the interval parameter of RvAl3 (interval/2).
HYDROLOGICAL SERVICES 4.1.3 Battery Voltage (BV) The RRDL-3 logger battery voltage is measured and displayed when the battery voltage command (BV) is executed as well as during a status window command (ST), a rain message (R), a river message (RV), and when any alarm occurs that generates a rain or river message. BV? 5 Battery Voltage: Syntax: BV On-line Help Reads logger supply voltage to one decimal point 4.1.4 Bye (BYE) The RRDL-3 logger has two distinct modes of operation.
HYDROLOGICAL SERVICES 5. 6. A CLEAR sequence is performed again to get the modem back into a known state. If there is more than one CALL NUMBER defined then return to step 2. On-line Help CLEAR1? 5 Clear1/2/3/4 Sequence Programmable string dialogue for terminating a comms call after transmission of an alarm or scheduled mesg. Sequence of up to 4 command strings with opt response to clear a call via an external comms I/F (Max 30 chars/seq)(~ = 0.
HYDROLOGICAL SERVICES 4.1.6 Communications (COM, SEND, EV, RE, RETRY) The communications of the RRDL-3 logger is set up by a combination of DIP switches and software flags. The configuration of all logger communications parameters is displayed in the comms window. (See section 3.1.4.
HYDROLOGICAL SERVICES As events occur they are transmitted on the serial port. A rain event is transmitted as a time, and a river event is transmitted as a time and river height. When an intelligent modem is connected to a logger it is undesirable for this to occur, so events may be turned off by using the event flag.
HYDROLOGICAL SERVICES 4.1.7 Date/Time Parameters (D, T, TO) The logger date and time is maintained in a battery backed Real Time Clock whose time base is adjustable by a trim capacitor on the circuit board. Time is displayed in 24 hour format separated by colons, and the date is displayed as day/month/year with slash separators. When entering the time and date all fields must be entered. Note that if the time is entered as T= then it will be reset to midnight 00:00:00.
HYDROLOGICAL SERVICES 4.1.8 Dump Log (DUR, CLR, DURV, CLRV, LOG) The loggers rain and river log data is stored in a compressed format in the on-board flash memory. The dump rainfall command (DUR) unloads the historical rainfall record from the start of the record to the most recent event stored. On completion of successful data retrieval, the memory remains intact until cleared by the clear rain log user command (CLR).
HYDROLOGICAL SERVICES CLR? 5 Clear Rainfall Log: Syntax: CLA On-line help Totally erases the rainfall log (OK when complete) The dump river command (DURV) unloads the historical river record from the start of the record to the most recent event stored. On completion of successful data retrieval, the memory remains intact until cleared by the clear river log user command (CLRV). When the memory becomes full, the logger stops logging and tacks a "Mem Full" message onto the end of an event message.
HYDROLOGICAL SERVICES the most recent data is always available. It is advisable that when changing the state of the Memory Wrap flag, the existing logged data be erased so that logging can start afresh. On-line Help MW? 5 Memory Wrap: Allows rain & river log to wrap around Erase logged data when changing this flag ! Syntax: MW or MW=ON or MW=OFF 4.1.9 Miscellaneous (ID, SI, MO, PASSWD, RESET, VER) The logger ID is set at time of manufacture and can only be read.
HYDROLOGICAL SERVICES PASSWD? Password: 5 On-line Help Four character passwd to allow user access to alter parameters or change existing passwd NOTE: Upper/lower case sensitive Syntax: PASSWD=**** To attempt access, or change password if access already accepted The reset command performs a hardware reset, but does not affect the time, date, parameters or logged data. On-line Help RESET? Reset: 5 Performs a reset of the logger.
HYDROLOGICAL SERVICES 4.1.11 River Parameters Quadrature (RVCHID, RVI, RVHR) The "River Channel ID" (RVCHID) is a 7 digit user definable number that should be set to uniquely set to identify the river channel.
HYDROLOGICAL SERVICES The analog 4-20mA pressure transducer that measures river depth connects to the RRDL-3 logger through a smart sensor interface. Zero depth is represented by 4mA and maximum depth is represented by 20mA. The "Transducer Reference" (TXR) parameter defines the 20mA depth expressed in metres of water. On-line Help TXR? 5 Transducer Reference: Defines the 4-20mA transducer max depth (What 20mA represents in terms of metres of water) Syntax: TxR Displays transducer ref TxR=030.
HYDROLOGICAL SERVICES 4.1.13 Status (ST, COM, R, RV) 4.1.13.1 The Status Window (ST) The Status Window returns a summary of station set-up details together with a report of current rainfall and river conditions on user command. Each set-up parameter is identified by name followed by its unique command keyword, (parameter abbreviation). The Status window provides a 'plain English' response for visual interpretation as displayed on a standard computer terminal when the ST command is issued.
HYDROLOGICAL SERVICES boundary is that of the next event outside the interval. 3. The Trend value = the most recent event within the time interval prior to now, minus the oldest event within that time interval of the same trend bias. 4. The Trend time = default time interval, unless a change of trend bias is detected within the interval then, Trend time = difference between now and the event time of the oldest event of same bias within the trend time window.
