PROBLEM TO BE SOLVED: To provide a numerical data monitoring processing system capable of reliably detecting a leakage value without needing a setting change operation in spite of a change in an input range in processing repeatedly inputted continuous values within a fixed range. SOLUTION: A home delivery locker 6 is stored with a sequence number attached to each dwelling unit, and the home delivery locker 6 transmits to an interphone system controller 4 continuous numerical data obtained by adding a dwelling unit number and information on the existence/absence of a home delivery article to the sequence number. The interphone system controller 4 reads the continuous numerical data sent from the home delivery locker 6, detects the upper limit value and lower limit value of the continuous numerical data, detects a changed upper or lower limit value of the continuous numerical data if the range of the continuous numerical data is changed, and automatically updates the upper or lower limit value to make it possible to continuously read numerical data.
