Constanta Vaga specialists developed, manufactured and put into operation a control system for dosed loading and shipment of grain (hereinafter referred to as CSD).

The result of the development was a modern electronic grain shipment control system, in which all product data (weight, time, date) and the necessary recipient details are stored in non-volatile memory and transferred to the enterprise’s 1C system.

The CSD system contains an operator panel with a touch screen, the software of which was developed by Constanta Weight specialists.

The panel screen shows a visual graphic diagram of the technological process of grain shipment (including indication of the weight of grain in weighing silos) and the state of the input signals of the EMS system. The operator has the opportunity to enter the value of the dose declared for shipment and the vehicle number, which allows for more accurate accounting of shipped products.

The system provides output control signals to actuators, automating the technological process and minimizing the influence of the human factor.

All electronic components are mounted in a metal cabinet with automatic heating and dust protection, ensuring a longer service life of the equipment.

This system provides the following functions:

• weighing grain in shipping silos;
• metered loading/unloading of grain into shipping silos in accordance with
  operator’s task;
• control of silo loading/unloading mechanisms;
• visual display of the technological process (mnemonic diagram);
• entry of shipping details by the operator;
• storing shipping information in non-volatile memory and transmitting it to the user’s PC;
• communication interface with PC;
• data exchange protocol compatible with the 1C program;
