The STM32 microcontroller based pulse intensity registration system for the neutron monitor
We present the outlines of a new microcontroller based data acquisition
system which is aimed for reliable operation in a typical cosmic ray particle
registration experiment. The system supports connection of up to 16 input
signals and ensures the following operation functionality: (1)stable monitoring
of the intensity of a digital pulse signal, or digitization of a continuous
potential level with a low time resolution (typically, in the limits of
1-100s); (2)registration of a continuous high-resolution (up to 5-10us) time
series of the intensity of input signal; (3)synchronization of registered time
series with both external (physical) or local (program-based) trigger signal;
(4)possibility of an on-the-fly change of the whole configuration of
informational system (both the combination and type of input signals, time
resolution and sum duration of the time series measurements, trigger logic,
etc) immediately in operation time through convenient communication with a
plain text message in dialog mode. In particular, the considered system is
applied now for a long-term, high precision measurement of the counting rate of
neutron signals at the NM64 type neutron supermonitor of the Tien~Shan mountain
cosmic ray station, with a real-time representation of the whole collected
dataset in a WWW database.Comment: communication at ISVHECRI 2016 and at the "10 Years Neutron Monitor

The system supports connection of up to 16 input signals and ensures the following operation functionality: (1) stable monitoring of the intensity of a digital pulse signal, or digitization of a continuous potential level with a low time resolution (typically, about 1 s–100 s); (2) registration of uninterruptable high-resolution (up to 5–10 μs) time series of the input signal intensity; (3) synchronization of registered time series with both external (physical) or local (program-based) trigger signal; (4) possibility of an on-the-fly change of the whole configuration of informational system (both the combination and type of input signals, time resolution and sum duration of the time series measurements, trigger logic, etc.) immediately in operation time through convenient communication by plain text messages in dialog mode.
