Abstract

The utility model provides an annunciator stability detection device, comprising an MCU, and a sound acquisition module, a relay module, a display module and a function extension module which are connected with the MCU, the above modules are powered by a power supply module, and the relay module uses a small voltage to control a large voltage. When the sound signal of the sound collection module is larger than a set decibel threshold value, the sound collection module is closed, and the MCU carries out high-threshold-value early warning through the relay module and carries out indicating lamp prompting. According to the signal machine stability detection device, through information collection of the sound sensor and detection of the main control MCU, an actual decibel value is obtained after signal operational amplification and value conversion, sound is interpreted at the same time, and then the situation that the output stability of a signal machine is influenced by different internal environment conditions of a factory workshop can be judged; the effect of judging the vibration intensity according to the volume of the sound is achieved, and is used as one of factors for judging the output of the annunciator.
