The invention discloses a remote air pressure monitoring method and a remote air pressure monitoring system of inflatable power equipment. The method comprises the steps of measuring test data in theinflatable power equipment via a sensor, and sending the test data to a repeater corresponding to the sensor; sending the test data to a remote service unit via the repeater; via the remote service unit, treating and storing the test data, and uploading the test data to a web server; and via the remote service unit, computing a yearly leakage rate according to the test data, and sending a test frequency command to the corresponding sensor via the repeater according to the yearly leakage rate. The system comprises a pickle monitoring unit including the repeater and the sensor, the remote service unit and a browsing terminal unit. According to the method and the system, remote monitoring on the internal air pressure data of the power equipment can be achieved, meanwhile a temperature parameter is monitored for assisting, the operational reliability of the inflatable power equipment is enhanced, the inspection work strength of field operation and maintenance personnel is reduced, and personal security of the field operation and maintenance personnel is ensured.
