摘要:
A dynamic alarm generation method of a biological particle monitor according to the present invention includes the steps of: (a) receiving particle information[i] from the biological particle monitor; (b) calculating an effective biological particle[i] and an upper bound[i] of the effective biological particle from the particle information[i]; (c) calculating a moving sum[i] of the number of times exceeding a relative concentration, a moving sum[i] of the number of times exceeding a long-term low concentration, and a moving sum[i] of the number of times exceeding a short-term high concentration from the upper bound[i] of the effective biological particle; (d) determining whether or not the moving sum[i] of the number of times exceeding the relative concentration, the moving sum[i] of the number of times exceeding the long-term low concentration, and the moving sum[i] of the number of times exceeding the short-term high concentration respectively exceed a relative concentration alarm criterion[i], a long-term low concentration exceeding time, and a short-term high concentration exceeding time; and (e) generating a corresponding alarm if it is determined that any one of the relative concentration alarm criterion[i], the long-term low concentration exceeding time, and the short-term high concentration exceeding time is exceeded, and steps (a) to (e) are repeated every unit time.

Disclosed therein is a system for removing interference in a navigation signal of global navigation satellite system (GNSS). The system includes: a signal reception processor being arranged as many as a plurality of GNSS modes and converting a navigation signal received from navigation satellites through an antenna into an intermediate frequency (IF) signal in digital form according to the respective GNSS modes; an interference remover for processing the IF signal to generate a single serial signal by time division, removing interference from the serial signal, and then distributing the serial signal according to the respective GNSS modes; and a GNSS receiver for receiving and processing the distributed serial signal. The system contributes to enhancement of productivity by eliminating interference with only a single interference remover irrespective of the number of GNSS modes.

Disclosed are a soft recoil system (200) and a cannon (100) having the same. The soft recoil system (200) includes: a cannon barrel returning device (210) mounted to a recoil device (160) for absorbing a recoil force occurring when ammunition is fired, and configured to backward press a breech ring (150) coupled to a rear end of the cannon barrel (120), such that the cannon barrel (120) is fixed to a preset position; a cannon barrel fixing device (220)installed at the recoil device (160), and configured to fix the cannon barrel (120) when the cannon barrel (120) returns to the fixed position; and a forward momentum generator (230) connected to the recoil device (160) and the breech ring (150), respectively, configured to forward move the cannon barrel by applying a force to the breech ring (150), such that the ammunition is fired while the cannon barrel (120) forward moves, and configured to reduce a recoil force by partially attenuating recoil momentum resulting from the firing of the ammunition, by forward momentum.
