description | The present invention relates to a method for reducing a rate of lightning damage to a low-voltage centralized reading system, comprising the following steps performed sequentially: (a) an electric field inductor is connected at a 485 communication port of a concentrator; a lightning triggering device is connected to the electric field inductor; (b) the electric field inductor monitors directions and strength of electric fields around the concentrator; when a field strength value induced by the electric field inductor is greater than a set threshold, a 485 communication line is disconnected while the lightning triggering device is switched on; and (c) when the field strength value induced by the electric field switched on is less than the set threshold, the 485 communication line is recovered while the lightning triggering device is switched off. The method of the present invention reduces the rate of lightning damage to the low-voltage centralized reading system, and improves the data acquisition accuracy of |
