Abstract

The utility model relates to a hydrology telemetering terminal based on a network transmission technology. The hydrology telemetering terminal comprises a microcontroller circuit board (1), the microcontroller circuit board is respectively connected with a water resources and hydrology collecting device (2), an external electrically erasable programmable read-only memory (EEPROM) (5), a real-time clock (3) with a digital oscillator (16), a light-emitting diode (LED) display (4), a general packet radio service (GPRS) device (6) and a storage battery (7) which is connected with a solar cell panel (8), and the GPRS device uses Huawei GTM-900C. Transmission speeds and information accuracy are seriously influenced due to the fact that most of hydrology information monitoring points are remotely and dispersedly distributed and traditional radio station forms are influenced by factors of geographic positions, weather and the like. However, the hydrology telemetering terminal can be not influenced by geographic positions, and by means of the hydrology telemetering terminal, hydrology information can be real-timely transmitted to a junction center only in places where mobile phone signals exist. The hydrology telemetering terminal is mainly applied to hydrology information data telemetering systems of water resources and hydrology industries.
