Abstract
The invention discloses a potential-based live derivation method in a passenger dedicated line comprehensive monitoring system, which includes: assigning a potential value of an incoming line as 65535 according to a normally live pressure voltage value, and if switches passed by a line are positioned in the switch-off state, subtracting one from the potential value when the line passes by one switch apparatus each time; and if the switches are positioned in the switch-on state, the potential value is -1, and when the potential value of each switch apparatus is positive, each switch apparatus and a power supply line connected with the same are live. The method adopts the switches to compute respective live conditions, namely, live derivation of each switch apparatus is computed according to the potential value and the on or off state of the respective switch of one adjacent switch apparatus, the switches without influence on the switch apparatus are not computed, and accordingly, when live derivation is computed by the system, the algorithm adopted by the method is efficient and can greatly reduce system resources consumed in computation of live states of the power supply lines.
