Fault location method of capsule type floor heating device

Abstract

The invention discloses a fault location method of a capsule type floor heating device. The fault location method is applied into a floor heating track. The fault location method comprises the steps that fault speech signals are acquired and unit impulse response is subjected to convolution to obtain binaural signals; and after the binaural signals pass through a Gammatone filter, sub-band signalsafter frequency division are obtained, dereverbration processing of minimum phase decomposition is carried out in each sub-band signal, and a generalized cross-correlation function is obtained by calculating the cross-correlation of various sub-bands after the inverse transformation from a cepstrum domain to a time domain. The fault location method takes binaural speech localization as a multi-classification problem, takes GCCF (Generalized Cross-Correlation Function) and an interaural level difference as localization characteristics to input into DNNs of a softmax regression structure on a top floor, outputs the probability of which a sound source is located in each direction, and takes a maximum probability azimuth as the position of the sound source. The fault location method is simpleand convenient in installation, and the capsule type floor heating device which can locate the fault is provided in an innovation mode.

Description

technical field [0001] The invention belongs to the technical field of floor heating, and in particular relates to a fault location method for a capsule-type floor heating heating device. Background technique [0002] Among the existing floor heating equipment, hydroelectric floor heating uses water and electrical appliances as the medium. It is heated by water and electrical appliances, and then dissipated heat through pipes and insulating layers. The whole section of heat radiates to the ground, consuming a lot of heat resources. Slow, high operating costs, unsafe problems of water leakage and electricity leakage in concealed projects cannot be avoided, and the worry about the future is that it cannot be repaired. The existing floor heating pipes are bent into a certain shape on site, and there is no special floor heating track. The present invention innovatively provides a track suitable for floor heating, which facilitates the operation of the capsule heating element and...

Problems solved by technology

At present, there is no corresponding technology at home and abroad that uses capsules as the medium for HVAC to replace water and electricity. It solves the problem of concealed engineering, but when the capsules in the capsule pipeline fail, how to accurately locate and inspect them maintenance is a problem
