Remote failure alarm system of pneumatic membrane pump based on NB-IOT

The invention relates to a remote failure alarm system of a pneumatic membrane pump based on NB-IOT. The remote failure alarm system comprises the pneumatic membrane pump, a data monitoring and transmitting device, a cloud server and a remote receiving terminal; the data monitoring and transmitting device is placed on a pneumatic membrane pump housing; and the data monitoring and transmitting device is connected with the remote receiving terminal through the cloud server. The motion frequency of a pneumatic motor of the pneumatic membrane pump is measured by using the data monitoring and transmitting device, so that whether the pneumatic membrane pump has a failure is detected, and when the pneumatic membrane pump has the failure, alarm data is transmitted to the cloud server, and professional maintenance staff receives an alarm signal through the remote receiving terminal. Whether the pneumatic membrane pump has the failure is judged through the times N of switching signals generatedin unit time, so that the
