Abstract:
1. A method for a photoelectric-type continuous measurement of a liquid level, wherein the method is applied to an apparatus for the photoelectric-type continuous measurement of the liquid level, the apparatus comprises at least one sensor module, and the sensor module comprises a plurality of cascaded sensors; wherein the method comprises: driving the sensors upwardly one by one, to perform measurements of liquid levels, after a light intensity of a probe light returned at a position of a sensor currently in a driving state is detected, performing an analogue-to-digital conversion on a voltage corresponding to the detected light intensity to obtain current analogue-to-digital conversion data, determining the liquid level at the position of a current sensor based on a preset correspondence between the liquid level and the analogue-to-digital conversion data, and after a current sensor module drives the respective sensors in the current sensor module in a time division way, summarizing the liquid levels correspondingly measured by the respective sensors to a transmitter module to analyze and process the summarized liquid levels to obtain a total liquid level of a currently measured liquid, and outputting the total liquid level in a specified interface form.
