The working principle of the self-switching signal dust removal device applied to multi-meter centralized meter reading is as follows:

before the device is started, the strain assembly 5 is in an equilibrium state, the spring 43 is in a stretching state, the lower contact ring 512 of the strain gauge 51 is positioned on the horizontal line of the high-level end of the lower inductor 7, the lower contact ring 512 is not positioned above the lower inductor 7, and the strain gauge 51 and the lower end branch pipe of the necking pipe 4 are provided with gaps for enabling air to flow.

Meanwhile, the guide vane 57 rotates in one direction in the fast flowing air to drive the fixing sleeve 56 to drive the strain block 51 to rotate in one direction, and the strain block 51 rotates between the limiting pieces 412 under the limiting of the brush 54 and the limiting piece 412, so that the lower contact ring 512 rotates above the lower inductor 7.

Along with the extension of ammeter case 1 live time, the adnexed dust on dust filter 12 surface is more and more, and the mesh that is blockked up is more and more, and the resistance that the air got into ammeter case 1 increases, makes ammeter case 1 air flow rate reduce, and until dust filter 12 is blocked up completely, no air gets into ammeter case 1. In the process, the upward thrust of the air to the strain assembly 5 is reduced until the upward thrust disappears, the strain assembly 5 gradually moves downwards until the strain assembly is in a balanced state, at the moment, the upper inductor 6 is separated from the upper contact ring 511, the lower contact ring 512 also moves downwards along with the upper contact ring and touches the lower inductor 7 and is communicated with the lower inductor 7, an electric signal is sent to the control device 2, the control device 2 controls the air driving device 3 to reversely operate, the air in the electric meter box 1 is driven to reversely flow, the air in the electric meter box 1 flows downwards from top to bottom, the flowing air presses the strain assembly 5 downwards, and the strain assembly 5 blocks the lower end branch pipe of the necking pipe 4.
