Automatic detection device for buzzer of single-phase electric energy meter

Abstract

The invention discloses an automatic detection device for a buzzer of a single-phase electric energy meter. The device comprises a rack. The rack is provided with one or more tools for the meter positions. The at least one or more tools for the meter positions is provided with a plurality of meter positions. A buzzer detection unit is arranged on the rack above the meter position tool wherein the buzzer detection unit comprises an upper-and-lower straight line driving mechanism on the rack. The lower end of the upper-and-lower straight line driving mechanism is provided with a sound silencing cover. The bottom of the sound silencing cover is provided with one or more cavities to hold the electric energy meters on the various meter position tools. Each cavity is provided therein with a decibel meter and comprises a host computer, a serial server and a monitoring module. The automatic detection device for the buzzer of single-phase electric energy meter can accurately determine whether the sound quality of the buzzer meets the requirement or not.

Description

technical field [0001] The invention relates to the technical field of detection devices for single-phase electric energy meters, in particular to an automatic detection device for buzzers of single-phase electric energy meters. Background technique [0002] At present, single-phase energy meters with buzzer alarm function are more and more widely used. The buzzer in the energy meter can generate an alarm function to inform users about the information about the energy meter when the energy meter is abnormal. For example, when the user's remaining power is insufficient, the buzzer can emit a beeping alarm sound to inform the user to pay the fee in time. For electric energy meters with buzzers, the buzzer is generally installed on the bottom shell of the electric energy meter or on the PCB board, and a sound hole is designed on the side of the electric energy meter to make the sound come out from the side of the electric energy meter. [0003] At present, with the gradual imp...

AI Technical Summary

Problems solved by technology

[0003] At present, with the gradual improvement of automation level, the detection of electric energy meters is becoming more and more automatic, but there is no special automatic detection device designed for the detection of buzzers, resulting in the detection of buzzers can only be carried out manually, which not only affects the work efficiency Low, and it is impossible to accurately judge whether the sound quality of the buzzer meets the requirements
