Further, the procedure for weighing the housed sheep in S1) was as follows:
t1) the weighing sensor continuously outputs millivolt measuring signals in working state, the weighing data conversion and transmission device converts the measuring signals into weighing data d (k) according to the preset sampling period T and sends the weighing data d (k) to the data acquisition management machine;
when a sheep enters an area formed by the weighing barriers for drinking or eating, the front hoofs of the sheep step on the weighing box-shaped flat plate to trigger the weighing sensor to output a non-zero signal, and after the data acquisition management machine receives a non-zero weighing data sequence, the data acquisition management machine starts to calculate a moving average value g (K + K-1) ([ d (K) + d (K +1) +. + d. + K-1) ]/K according to a preset window periodicity K for the received weighing data { d (K), d (K +1), ].
After drinking or eating begins, the head of the sheep is positioned under the radio frequency electromagnetic wave transceiver, the ear tag type transponder arranged on the ear of the sheep is activated by the electromagnetic wave transmitted by the radio frequency electromagnetic wave transceiver, namely, the electromagnetic wave signal containing the transponder number is transmitted, the radio frequency electromagnetic wave transceiver receives the signal and then transmits the serial number data ID of the ear tag type transponder of the sheep to the data acquisition manager, and the data acquisition manager receives the serial number data ID of the ear tag type transponder of the sheep, associates the serial number data ID with the moving average value g (K + K-1) of the weighing data and records the serial number data ID as (ID, g (K + K-1)).
T2) calculates the deviation E (K + K) between two adjacent moving averages corresponding to the numbered data ID as g (K + K) -g (K + K-1), and when the absolute value of E (K + K) is smaller than the preset value E, i.e., -E (K + K) | < E, the data collection manager stores the array { ID, current time, g (K + K) } in the sheep weighing data log file.
T3), the data acquisition management machine compares g (K + K) data corresponding to adjacent "current time" in an array { ID, current time, g (K + K) } with the same ID on the previous day and the current day, if a large deviation occurs and is larger than a preset upper limit, for example, | g (K1+ K) -g (K2+ K) > MAX (g (K1+ K), g (K2+ K)) > 25%, the data acquisition management machine sends out a fault early warning to prompt for field inspection; if no major deviation occurs, go to step T4).
T4), the data acquisition management machine arranges the data in the sheep weighing data log file of the previous day every day, extracts date data date from the current time in an array { ID, current time, G (K + K) } with the same ID, calculates the average value G of the weighing data G (K + K), forms an array { ID, date, G } and stores the array { ID, date, G } in a sheep weighing database.
T5) the data collection management machine deletes the sheep weighing data log files before the preset retention time period in a rolling mode every day.
T6) back to step T1).
