Embodiment Construction

[0046] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] The industrial process of flotation is a three-layer control structure, which is composed of operation optimization control layer, process control layer and flotation process layer, such as figure 1 As shown, in this embodiment, the flotation process layer can be realized by hardware-in-the-loop simulation experiments, and the virtual object layer is the simulated virtual flotation process. Operation optimization control layer: Operation optimization control layer includes operation optimization control computer, which reads the current working conditions from the process control PLC through industrial Ethernet, and then uses the dual-network operation layer algorithm to give the optimal underlying control setting value. The process control layer includes PLC, which mainly realizes the underlying control functions, as wel...

Abstract

The invention provides a system and method for controlling the operation of a flotation industrial process under a dual-network environment. The system comprises a PLC system, an operation optimization control computer and a DSC monitoring computer. The method comprises the steps that mineral earnings, mineral consumption, target economic indicators, concentrate grade target values and tailing grade target values are set; mud height, mud quality, foam quality, feeding pulp flow and tailing flow are obtained in real time and are transmitted through an industrial Ethernet; static optimization and dynamic optimization are carried out on the concentrate grade target values and the tailing grade target values; the operation of the flotation industrial process is controlled according to the optimization value of the concentrate grade target values and the optimization value of the tailing grade target values. The preset economic indicators can be tracked, and the effect that economic benefits are controllable is achieved. The operating layer of the whole system is stable within a certain packet loss probability range and a certain noise amplitude value, and the residual error is small or is avoided in the stable state.

Description

technical field [0001] The invention belongs to the field of industrial control, and in particular relates to a flotation industrial process operation control system and method in a double-network environment. Background technique [0002] Flotation is a process of separating the flotation pulp into qualified concentrates and tailings according to the differences in the physical and chemical properties of the mineral surface to achieve effective separation. The harsh production environment, complex process, and limitations of testing instruments and control devices in the flotation process lead to a low level of automatic control of the flotation process. The actual flotation process is performed manually by workers on site. The traditional operation control can only adopt the control method of manually setting the set value of the equipment layer loop, that is, the open loop of the operation layer, but because the manual control cannot adjust the set value in time and accur...
