Zero correction method and system for electronic belt scale

The invention discloses a zero point correction method and system for an electronic belt scale, and the method comprises the steps: setting and manufacturing a one-key zero setting button, and setting a tare weight deviation set value and zero setting times, after the one-key zero setting button is pressed down, zero setting can be carried out for many times according to the set zero setting times, and the zero point of the electronic belt scale is corrected. After each time of zero setting, a tare record after zero setting is automatically transmitted to a tare record table of a central control room, meanwhile, a tare value of the current time of zero setting is automatically compared with a tare value of the last time of zero setting, and if a tare deviation after comparison is smaller than a tare deviation value set value, the next time of zero setting is automatically started after time delay until zero setting is finished; if the tare deviation is larger than the tare deviation set value, an alarm is giv
