METHOD FOR DETECTING AN ELECTRICAL CONTINUITY FAULT IN A NETWORK OF METALLIZATION STRIPS AND DEVICE FOR IMPLEMENTING SAME

摘要

A method and device for detecting an electrical continuity fault between a first and a second points of a network of metallization strips, including determining, from mapping, a length or a duration of a shortest path between the first and the second points, sending, at the first point, a signal in the network, detecting, at the second point, the signal sent, measuring a duration between the sending and the detection of the signal, knowing the speed of propagation of the signal in the metallization strips, determining the presence of at least one electrical continuity fault if the distance travelled calculated from the measured duration is different from the length of the shortest path determined from the mapping or if the measured duration is different from the duration to travel the shortest path determined from the mapping.

1. A method for detecting an electrical continuity fault between a first and a second points of a network of metallization strips, the network being defined by a mapping listing, for each metallization strip, its length, the method comprising:
determining, from the mapping, a length of a shortest path between the first and the second points; sending, at the first point, a signal in the network; detecting, at the second point, the signal sent; measuring a duration between the sending and the detection of the signal; and knowing speed of propagation of the signal in the metallization strips, determining the presence of at least one electrical continuity fault if the distance travelled calculated from the measured duration is different from the length of the shortest path determined from the mapping.
