AI Technical Summary

Problems solved by technology

At present, there are instruments on the market for the identification of power-off cables, as well as instruments for the identification of live cables. However, in the actual use process, due to the complex and harsh environment of the construction site, the electronic detection equipment is seriously disturbed by the outside world and drifts.

The above-mentioned products are all detected by signal injection method, and there is distortion when the signal strength is weak, and it uses simple frequency modulation communication technology in information transmission, which is seriously disturbed by noise and distance, and the security and confidentiality are not strong, so it is easy to be detected by the third party. Induced by three parties after receiving or cracking, poor reliability

Because these devices generally have interference and misjudgment phenomena, they bring great safety hazards when they are used in construction.
