Application


Automatic measuring post (AMP)

Smart probe AT2343 provides absorbed gamma radaition dose rate measuring in the range from 25 nGy/h to 10 Gy/h. Two-chamber Geiger-Muller counters are used as detectors. Data from a smart probe is transmitted to a uniform terminal controller by RS485. Wind speed and direction sensor, precipitation sensor and temperature sensor, external indication board can be connected to the terminal controller. It is possible to provide the terminal controller with a radio unit, a radio station, a radio mast with TL antenna and (or) a telephone unit taking into account communication channels in use. Applied software of automatic measuring post provides digital data forwarding, so it is possible to extend automatic measuring post network to big distances. The system supplies from an uninterruptible power supply. There are two operation modes: an economical mode for operation under normal environment and the mode with frequent data transmission for operation under emergency radiation surrounding. It is possible to create independent databases and maintain data keeping for more that a year due to the nonvolatile memory.

Local response center (LRC)

PC is used as the central control unit, which is delivered together with the terminal controller. Applied software runs under Windows® and provides system configuration, data readout and its processing. There are a map of controlling area and dose rate value in control points on PC display. Dose rate values can be presented as a table or a graph with value averaging for any time period. The processing algorithm detects a sudden dose rate change and switches the emergency operation mode as a result. Alarm threshold exceeding in any smart probe or failure of any system unit are displayed on PC as color zones and accompanied by audible alarm. Acquired from smart probe dose rate results are kept in the datatbase.
