Specifically, the basic principle of monitoring the safety state of the handrail by using a resistance method is a multi-resistance parallel numerical calculation principle. The resistance values of the metal bodies of the vertical rods 4 which are measured independently are respectively R1, R2, R3, R4 … Rn-1 and Rn; the vertical rods 4 form a parallel system through the protective cross bars arranged on the vertical rods, and the resistance value measured on a single vertical rod 4 after parallel connection is the resistance value of the whole parallel system, and the theoretically calculated value is 1/R and is 1/R1+1/R2+1/R3+1/R4 … 1/R (n-1) + 1/Rn. Assuming that the resistance values measured individually for each of the vertical bars 4 are identical (i.e., R1R 2R 3R 4 … Rn-1 Rn), the resistance values measured for each of the vertical bars 4 after parallel connection are R and R/n. Therefore, under the condition that the vertical rods 4 are connected in parallel or not, the resistance values R measured in sequence for a single vertical rod 4 are different from R to form a magnitude relation, so that the state is very easy to judge. Even if factors such as the difference of the initial resistance value of each vertical rod 4, the data difference measured by each vertical rod 4 after parallel connection and the like are considered, allowable deviation statistical deviation values alpha and beta are set, and the fact that the protective cross rod on the vertical rod 4 is detached can be judged only by actually measuring the resistance R of a single vertical rod within the range of [ R single-alpha, R single + alpha ]; the protective cross bar on the vertical bar 4 can be judged to be connected with the vertical bar 4 well within the range of R (R is combined to-beta, R is combined to + beta).
