The invention discloses a time induction-based telemetry data still automatic detection method and system. The method includes the following steps that: a new storage space is generated every set time; a mapping table of telemetry points and storage spaces is created; storage spaces corresponding to telemetry points are searched according to mapping relations between the telemetry points and the storage spaces; all the storage spaces are traversed, the difference value of the end time of the data receiving of each storage space and current time is judged; and if the difference value exceeds aset threshold value, it is determined that telemetry data still occurs in a telemetry point corresponding to the storage space, and warnings are sent to monitoring personnel according to the condition. According to the method and system of the invention, when telemetry data are received, time-based inductive classification is performed on the telemetry points and the telemetry data, so that time-based storage spaces with no intersections are dynamically generated, and therefore, storage spaces which exceed specified time only need to be checked out, detection data quantity is reduced, and therefore, the method and system have high detection performance.
