Abstract

Sposób synchronizacji sejsmicznych i sejsmoakustycznych sieci pomiarowych zwłaszcza kopalnianych sieci iskrobezpiecznych polega na tym, że w każdym kanale transmisji okresowo inicjowany jest pomiar wartości korekty czasowej (2Ki) propagacji sygnału od odbiornika (OD) do nadajnika (ND) i z powrotem. Po czym w pętli fazowej odbiornika (OD) zawierającej zegar czasu wewnętrznego (RT) generowany jest jako korekta w trybie ciągłym przesunięty sekundowy wewnętrzny takt wzorcowy (TWa) z wyprzedzeniem w fazie o korektę czasową (Ki) w stosunku do sekundowego taktu wzorcowego (TW) zegara (GPS) z jednoczesnym przyspieszeniem czasu zegara czasu wewnętrznego (RT) o czas korekty czasowej (Ki). Ponadto w trybie ciągłym generowany jest, N razy częściej, korzystnie 250 razy, wewnętrzny takt synchronizujący (TSa) z wyprzedzeniem w fazie o korektę czasową (Ki), w stosunku do sekundowego taktu wzorcowego (TW), kluczujący wyjście przetwornicy zasilająco separującej (PZ) zasilającej iskrobezpiecznie linię teletransmisyjną (TR). Układ w bloku liniowym (BL) odbiornika (OD) ma zwierający linię teletransmisyjną (TR) klucz półprzewodnikowy (KL) odbiornika (OD) połączony poprzez transoptorowy separator galwaniczny wejściowy (SG2) bloku liniowego (BL) z wyjściem (b) mikrokontrolera (MK). Z kolei w nadajniku (ND) blok formowania (UF) taktu synchronizującego (TS) połączony poprzez kondensator (C) z blokiem liniowym nadajnika (BLN). Przy czym wyjście bloku formowania (UF) połączone jest z jednym z wejść detektora fazy (DFN) mikrokontrolera nadajnika (MKN). Z kolei w bloku liniowym nadajnika (BLN) znajdują się transoptorowe separatory galwaniczne sygnałów (SG3) i (SG4).The method of synchronization of seismic and seismic-acoustic measurement networks, especially mine intrinsically safe networks, consists in the fact that in each transmission channel the measurement of the time correction value (2Ki) of signal propagation from the receiver (OD) to the transmitter (ND) and back is periodically initiated. Then, in the receiver's phase loop (OD) containing the internal time clock (RT), a continuous second internal reference clock (TWa) is generated as a correction in continuous mode, in advance in phase by time correction (Ki) in relation to the second reference clock (TW) clock (GPS) with simultaneous acceleration of the time clock internal time (RT) by time correction time (Ki). In addition, in the continuous mode, N times more often, preferably 250 times, an internal synchronization cycle (TSa) is generated in advance by a time correction phase (Ki), in relation to the second reference cycle (TW), the key output of the power supply separating converter (PZ) supplying intrinsically safe teletransmission line (TR). The system in the receiver's linear block (BL) (OD) has a shorting teletransmission line (TR) semiconductor key (KL) of the receiver (OD) connected via the optocoupler input galvanic separator (SG2) of the line block (BL) with the output (b) of the microcontroller (MK) . In the transmitter (ND), on the other hand, the forming block (UF) of the synchronization clock (TS) connected via a capacitor (C) to the transmitter line block (BLN). The output of the forming block (UF) is connected to one of the phase detector inputs (DFN) of the transmitter microcontroller (MKN). In turn, the transmitter line block (BLN) contains transoptoric galvanic signal separators (SG3) and (SG4).
