A parameter monitoring module applied to a fermentation tank

Abstract

The application provides a parameter monitoring module applied to a fermentation tank, comprising an acquisition module, a signal processing module and a wireless transmission module; the acquisition module comprises a pH acquisition module and a DO acquisition module, the signal processing module comprises a control unit MCU provided with an ADC module, the ADC receives a voltage signal of the acquisition module and carries out data processing through the MCU; the wireless transmission module comprises an RS485 communication module, and the RS485 is used for sending the data processed by the MCU. The parameter monitoring module of the fermentation tank can simultaneously or individually measure pH value, DO value and temperature value, is mutually isolated, and there is no mutual interference between channels; the module has two data transmission modes of RS485 and 4-20mA, is mutually isolated, and there is no mutual interference between channels; the module can set a filtering level, reduces jumping interference, and the value is more stable. The measured value is accurate, the interference resistance is high, the integration degree is high, the monitoring interval is large, and the application range is wide.
