Distributed quantitative loading control system for Distributed Batching spot quantitative loading control system is the core of the intelligent controller system to solve the oil and chemicals in the loading operation is slow, low accuracy, prevent risk cans and poorly grounded and so on. The system has high accuracy, fast response, high security features. It can be achieved with the meter. Level switches, control valve is connected to control automatic loading car, train trestle. For petroleum, chemical, oil refining and other enterprises on-site quantitative loading control and control room management. Liquid material loading system to achieve quantitative barrels, and automatic temperature compensation, anti-overflow chain, explosion-proof material, making the system safe and reliable, on-site quantitative loading controller can be installed in the vicinity of the stack loading station, by the field staff on the spot Operating and monitoring sends the material, from the industrial computer control room of the entire trestle centralized control and management, constitute a real distributed control system. System configuration flexibility, and satisfy the requirements of different users. Function data acquisition and processing functions: control device for a pulse, grounding, spill, valves and other input control signal analysis and processing, reducing data transfer first bit machine, PC for data storage. Security alarm function: When loading or front loading system detects the static grounding bad, the system will automatically alarm, and promptly refused to stop loading or loading. Loading process if the detected level switch operation, the system immediately halt loading operations and alarm. Analog display: in the loading process, the system can simulate live shows loading state and the ground state of the valve, so that the control room operator can easily understand the situation on-site loading. Rights management features: the system set up three levels of jurisdiction: Operator level, Administrator level and engineer level. The operator level can operate loading operations; administrator level can query the data, backup and recovery operations; engineer level system parameters can be set. Data query, print and summary: The system in operation, automatically generated data files and loading operations of log files, the user has administrator rights can query data; can be issued the appropriate documents according to the user's needs. Operation logging: the system is running, the automatic recording operation contents of the operator, for the management of the archive query.
