Problems solved by technology

[0003] Engineering safety monitoring instruments and secondary instruments or automatic acquisition equipment are directly connected by cables, but in the process of data acquisition, sometimes some data needs to be collected manually at a certain position in the middle section of the transmission line At this time, the usual practice is to cut off the cable, and then connect the cable to the equipment for manual data collection. This method is very laborious and will cause great damage to the transmission line.

Description

technical field [0001] The invention relates to the technical field of measurement communication, in particular to an engineering communication transfer device and system. Background technique [0002] At present, most engineering safety monitoring instruments (such as various sensors) need to be connected with secondary instruments or automatic acquisition equipment to measure the target physical quantity of the measured object. [0003] Engineering safety monitoring instruments and secondary instruments or automatic acquisition equipment are directly connected by cables, but in the process of data acquisition, sometimes some data needs to be collected manually at a certain position in the middle section of the transmission line At this time, the usual practice is to cut off the cable, and then connect the cable to the instrument and equipment for manual data collection. This method is very laborious and will cause great damage to the transmission line. Contents of the in...
