the background management module is provided with a timing area alarm scoring parameter Fz, when the monitored article A is in a timing area, the background management module records the time length of the monitored article A in the timing area as T, the background management module calculates the timing area alarm scoring F of the monitored article A in real time, F = T x T + H x H, wherein T is a calculation compensation parameter of the time length T to the timing area alarm scoring F, H is the distance from the radio frequency identification device at the position where the monitored article A is located to a safety area, and H is a calculation compensation parameter of the timing area alarm scoring F;
the background management module compares F with Fz,
when F is less than or equal to Fz, the background management module judges that the position of the monitored article A is in compliance;
and when F is larger than Fz, the background management module judges that the position of the monitored article A is not in compliance.
2. The internet of things identification and management system based on radio frequency technology as claimed in claim 1, wherein the background management module is provided therein with a first preset duration to timing zone alarm score compensation parameter value T1, a second preset duration to timing zone alarm score compensation parameter value T2, a third preset duration to timing zone alarm score compensation parameter value T3, a first preset monitored item being in a timing zone duration evaluation value T1, a second preset monitored item being in a timing zone duration evaluation value T2, wherein T1 < T2 < T3, T1 < T2, the background management module comparing the duration T with the first preset monitored item duration evaluation value T1 when in the timing zone, the second preset monitored item duration evaluation value T2 when in the timing zone,
when T is less than or equal to T1, the background management module selects the value of T1 as T;
when T1 is larger than T and smaller than T2, the background management module selects the value of T2 as T;
and when T is larger than T2, the background management module selects the value of T3 as T.
3. The internet of things identification and management system based on radio frequency technology as claimed in claim 2, wherein the background management module is provided therein with a first preset distance to timing region alarm score compensation parameter value H1, a second preset distance to timing region alarm score compensation parameter value H2, a third preset distance to timing region alarm score compensation parameter value H3, a first preset monitored item is located in a timing region distance evaluation value H1, a second preset monitored item is located in a timing region distance evaluation value H2, wherein H1 < H2 < H3, H1 < H2, the background management module compares the distance H with the first preset monitored item distance evaluation value H1 when located in the timing region, the second preset monitored item distance evaluation value H2 when located in the timing region,
when H is less than or equal to H1, the background management module selects the value of H1 as H;
when H1 is larger than H and is smaller than or equal to H2, the background management module selects the value of H2 as H;
and when H is larger than H2, the background management module selects the value of H3 as H.
4. The identification and management system of the internet of things based on the radio frequency technology as claimed in claim 3, wherein a detection interval duration Pz is provided in the background management module, the background management module times the radio frequency identification interval duration each time the monitored object A is subjected to radio frequency identification, the timing duration is P, the background management module times the radio frequency identification interval duration again after the next radio frequency identification is completed, the background management module compares the timing duration P with the detection interval duration Pz in real time,
and when P is larger than Pz, the background management module judges that the target of the monitored object A disappears, and controls the alarm module to give an alarm.
5. The internet of things identification and management system based on radio frequency technology as claimed in claim 4, wherein the background management module integrates the position information of the monitored article A obtained by each radio frequency identification device in the management area to generate a moving route B of the monitored article A in the management area;
for similar articles, the background management module integrates the moving route, analyzes according to the integrated moving route, and iteratively adjusts the size and the position of a safety area and a timing area in a management area.
