The invention relates to the technical field of drainage management, and discloses a drainage
pipe network mixed connection and misconnection checking
system, method and device, and the
system comprises an infrasonic wave
fingerprint sounder, an infrasonic wave
fingerprint receiver and a data background which are in
wireless connection in sequence. The infrasonic wave
fingerprint sounder is arranged at a
pipe opening of a target drainage pipeline, and the infrasonic wave fingerprint
receiver is arranged in a drainage pipeline opening in a target diagnosis area; the infrasonic wave fingerprint generator encodes the infrasonic wave fingerprint to obtain an encoded infrasonic wave
signal, and sends the encoded infrasonic wave
signal into the target drainage pipeline; the infrasonic wave fingerprint
receiver collects infrasonic wave fingerprint signals of the drainage pipeline opening in the target diagnosis area; and the data background performs pipeline communication detection and mixed and wrong connection point judgment based on the coded infrasonic wave
signal and the infrasonic wave fingerprint signal to obtain a drainage
pipe network mixed and wrong connection
troubleshooting result. According to the method, the accuracy of a drainage pipe network mixed connection and misconnection
troubleshooting result is ensured, and the
troubleshooting efficiency is improved.
