The present application relates to a holding brake monitoring circuit system (20), an elevator system, and a holding brake monitoring method. The holding brake monitoring circuit system (20) comprises: a plurality of opening sensors (201, 202, 203, 204) corresponding to holding brakes, wherein the number of the opening sensors (201, 202, 203, 204) is an even number greater than 3, and the opening sensors (201, 202, 203, 204) are configured to be paired to form at least two working groups, and each of the working groups is configured to output an output signal (212, 213) for judging status of the holding brake(s). The holding brake monitoring circuit system (20) can monitor working status of the holding brakes in a group manner.
