the main control module controls the on-off combination of the left multi-way switch and the right multi-way switch by controlling the multi-way switch control module, reads an actual resistance value of a cable core wire to be detected, reads an on-off mark between the cable core wires to be detected from the Access database, and compares the on-off mark with the mark to judge whether the connection and insulation states between the core wires of the cable to be detected are normal or not.
9. The detection method according to claim 8, wherein the on-off flag is "1", the main control module reads that the resistance value between the core wires is less than 0.5 Ω, the communication is normal, otherwise, the communication is not normal; and under the condition that the on-off mark is '0', the resistance value of the core wire read by the main control module is not less than 0.5 omega, the insulation is normal, and otherwise, the insulation is abnormal.
