The pressure detection device comprises a pressure sensor module, an NB-IoT communication module, a communication module, an SIM card module, a power supply module and an antenna module. The communication module is electrically connected with the NB-IoT communication module and the pressure sensor module. The NB-IoT communication module is further electrically connected with the SIM card module and the antenna module. The power supply module is electrically connected with the NB-IoT communication module; the pressure sensor module is used for reading a pressure signal of a pressure sensor; and the NB-IoT communication module is used for processing the received pressure signal and transmitting the processed pressure signal to the cloud platform server through the antenna module. The pressure detection device can transmit the received processed pressure data to the cloud platform in real time, can receive the detected pressure value in real time, can timely find the abnormality of the pressure value, and can timely check the fault to prevent the fault.
