Signal double-side output type liquid leakage sensor fabric

Abstract

The invention discloses a signal double-side output type liquid leakage sensor fabric. Conductive weft yarns are woven in a main fabric body at intervals, conductive warp yarns are woven in a cloth edge area on one side of the fabric, and the conductive weft yarns and the conductive warp yarns are spaced by non-conductive warp yarns; the cloth edge area on one side includes an upper warp yarn layer and a lower warp yarn layer, and there are 2N conductive warp yarns in total, wherein N is a positive integer, the conductive warp yarns are separated into two groups, each group includes N conductive warp yarns, one group is arranged in the upper warp yarn layer, and the other group is arranged in the lower warp yarn layer. Every two conductive weft yarns serve as one circle, wherein the firstconductive weft yarn in contact with one conductive warp yarn group is electrically connected with the conductive warp yarn group and separated and electrically isolated from the other conductive warpgroup at the same time, mutual separation and electric isolation are realized by enabling the conductive weft yarn to pass through the lower portions or upper portions of at least three non-conductive warp yarns around the corresponding conductive warp yarns, and the contact or isolation situation between the second conductive weft yarn and the corresponding conductive warp yarns is contrary to that of the first conductive weft yarn.

Description

technical field [0001] The invention relates to a liquid leakage sensor fabric, in particular to a signal double-sided output type liquid leakage sensor fabric, which belongs to the field of textile technology and sensor technology. Background technique [0002] At present, there are some liquid leakage sensors on the market, which can be applied to liquid leakage detection in computer rooms, smart homes, etc. This type of sensor works by using the conductive properties of the liquid. The main component is a probe with two electrodes. When working, the probe is placed in the area where the liquid leaks and flows to achieve detection. The disadvantage of this type of sensor is that the liquid leakage must reach a certain amount to achieve the effect of simultaneously immersing both electrodes of the probe. However, for some special occasions, such as during the transportation of chemically polluted liquids, if dripping occurs at the flange connection of the pipeline, the use...

Problems solved by technology

[0005] For this reason, the object of the present invention is to provide a kind of signal double-sided output type liquid leakage sensor fabric, to overcome the sensor fabric that exists in the prior art can not be cut along warp direction, also need to do other processing after fabric weaving and cause processing efficiency Low, and due to the need for two small clips to clamp the two sides when outputting the signal, it is inconvenient to use and other defects
