Monitoring reset system

Abstract

The invention discloses a monitoring reset system which comprises an oscillator unit, a counter unit and a signal regulator unit. The oscillator unit is used for generating reference square wave signals. The counter unit is used for receiving the reference square wave signals, carrying out counting on the reference square wave signals, and outputting jump signals. The signal regulator unit is used for receiving the jump signals and dog feeding signals, and providing various types of reset signals for monitored systems through internal regulating circuits. The monitoring reset system can provide multiple paths of reset signals with adjustable overflow cycles, pulse widths, electrical levels and driving capacity simultaneously. The electrical levels, the pulse widths, the driving capacity and the like of the reset signals achieved through the monitoring system can be given out through the signal regulator unit in a matching mode. The overflow cycles of the reset signals achieved through the monitoring system can be given out through the oscillator unit and the counter unit, and the adjusting range of the overflow cycle is from a few seconds minimally to a few days maximally.

Description

technical field [0001] The present invention relates to ocean monitoring equipment, more specifically, to a monitor reset circuit in the ocean monitoring equipment. Background technique [0002] With the rise of the blue ocean economy, marine monitoring equipment has also developed rapidly. Marine monitoring equipment needs to operate at sea for a long time, with high maintenance costs and long operating cycles. Therefore, the stability requirements are high. For example, the maintenance cycle of marine monitoring buoys, marine submersible buoys, and seabed foundations is more than one year. The stability of marine monitoring equipment largely depends on the stability of the equipment's electronic system. A stable marine monitoring device not only requires reasonable circuit and program design, but also requires some special technologies to further ensure its stability. [0003] An important guarantee for the stability of electronic equipment is the watchdog circuit, which...

Problems solved by technology

[0006] In short, there are certain defects in the monitoring function of the watchdog circuit, which are not suitable for the use of marine monitoring equipment, mainly including: the reset signal provided is single, only to reset the CPU or chip; the driving ability is limited, and the power supply of the entire device cannot be Carry out monitoring and reset; the reset period is short, and the full-cycle monitoring of complex systems cannot be realized
