A recently granted patent (Publication Number: US11914418B2) discloses a data acquisition system that includes a signal transmission line with multiple signal delay units connected in series, each with an acquisition end for collecting signals. Corresponding acquisition units are connected to each delay unit to collect signals. A clock unit with inversion units and signal delay units generates a control signal for signal acquisition. A comparison unit compares the control signal period with a standard signal period and adjusts the supply voltage for the transmission line and clock unit to maintain a specific ratio between the two periods within a predetermined range.
Furthermore, the patent details a method for controlling the data acquisition system by receiving signals from acquisition units, calculating processing times for each signal, and transmitting instruction signals to the clock unit based on these processing times. The instruction signals control the switch unit at the output end of the signal delay unit to trigger the clock unit to send control signals for signal acquisition. Additionally, the patent includes a control device and apparatus with processors and memory to execute operations for controlling the data acquisition system based on received signals and processing times, ensuring accurate signal acquisition at the acquisition end.
