The on-line laser coding and weighing control unit can control the light output of the laser and the angular deflection of the vibrating mirror, and can collect the speed of the production line in real time to generate a speed error compensation signal. The weighing operation unit is responsible for the man-machine interaction between the system and the operator. Through the weighing operation unit, the operator can compile user-defined codes and control the operation and stop of the system. After the weighing operation unit accepts the relevant operation of the operator, it will be forwarded to the main control unit for execution.

The core part of the coding weighing system, data acquisition and data association, is constructed according to the principle of finite automatic state machine, using the post-association mode, which can ensure that the product supervision code of weighing is completely consistent with the associated data uploaded to the electronic supervision network. According to the site and environment of each product production line, as well as the process and operation requirements of packaging and weighing, the collection and association of the supervision code of the products in the network, the mixed mode of automatic collection and manual collection (referred to as the automatic line mode).

The Read the code weighing system realizes the automatic control of the whole system through the electronic scale, the weight is picked up through the pressure weighing module, and the weight signal is picked up for the transmission process and control requirements, including control scanning, coding equipment, printing equipment and other linkage work.
