Integrating existing stations to data collection

In these tasks, there are several possible ways to implement them. This page lists prerequisites and suggestions for best solutions as seen by FMI. There may also be workarounds suggested where optimal solution is not currently available.

Importance for datacollection should be defined by NHMS with help of FMI.

Default datacollection method is assumed to be TCP/IP-connection (LAN, GPRS, Radio, Satellite..). Details of datacollection must be decided individually for each station network and even on individual station.

Most of the work should be done by NHMS experts with advices and guidance from FMI.

Please feel free to comment and improve proposals. In case of questions please contact to Mr. Sami or any other Promoserv project members from FMI.

Automatic stations

NHMS AWS

(By Mr. Han from IMHEN)

TODO

  • Find out how receiving end is working (NHMS)
  • Document the dataformat used
  • Create program which receives message from station and sends it via socket to server

OR

  • Create (perl) program which receives message and stores it to database using NHMS::Parser-modules provided by FMI

Importance for datacollection

Possible workarounds

  • Read data from files of the receiving computer and send them to server

NHMS automatic precipitation stations

(By Mr. Han from IMHEN)

TODO

  • Find out how receiving end is working (NHMS)
  • Document the dataformat used
  • Create program which receives message from station and sends it via socket to server

OR

  • Create (perl) program which receives message and stores it to database using NHMS::Parser-modules provided by FMI

Possible workarounds

  • Read data from files of the receiving computer and send them to server


Milos 500 networks

These stations are probably installed with default setup provided by Vaisala. Please note that it differs from FMI-setups quite a lot. FMI has done programming and datacollection of M500 inhouse.

  • Network in North Vietnam
  • Italian AWS-installation?

TODO

  • Document the installation of station network
    • How stations are collected?
    • What is their data format?
    • Where is data stored and how?
    • Is it possible to connect directly to serial port of Milos 500-station?
    • Is it possible to read data from collecting server?
    • Is it possible to access stations remotely?

Importance for datacollection

Possible workarounds

  • Read data from data collection server or from database


South Korean AWS at Hymenet

Station is using binary format. If it is possible to decode binary format, station can be added to data collection. If decoding of the format is not possible or is too difficult, this station is ignored.

FMI proposes reading data from files

TODO

  • Decode binary format and convert it to ASCII-format
    • Needs new program (NHMS)
    • Decoding needs probably help from Korean manufacturer

Importance for data collection

Possible workarounds

  • Read data from files stored to workstation and send to listener
    • Needs program to read data from files (NHMS).

Other automatic stations

These guidelines will meet all stations

TODO

  • Find out data format in use and how it can be decoded
  • Is it possible to get data from serial port?
  • Can station send data to serial port or TCP/IP socket or must it be collected by some program?
  • What data communication methods are available?

Possible workarounds

Manual stations

Manual weather and hydrological stations can be integrated to data collections. The easiest way to do it, is to create WWW-page where people on station can submit their observations. In case there is no internet/Intranet connection at stations, submitting to www-page can be done by operator who receives the message by telephone.

This data collection can be tested and run in parallel with operational data collection. It requires only little additional work by staff at station.

Format and exact functionality of www-page should be discussed with FMI. FMI is currently testing similar system in order to replace old programs at manual stations.

FMI proposes that both ways, TODO and Workaround would be build as training examples

TODO

  • Create test version of webpage to Promoserv-server
  • Plan and design safe access-controls for web-page (At least useraccounts and passwords for each station).
    • Internal network would be best solution but fixed IP-addresses help as well

Possible workarounds

  • Fetch data from database of IT-center
