Description
Technical Field
The invention relates to the field of mine system control, in particular to a one-place multi-control integrated cooperative control method.
Background
Mine system control refers to a technique for monitoring, controlling and optimizing various equipment, processes and parameters in the mine production process. Different from the common factory control, the mine system has a very wide distribution range, is even more than kilometers away from the ground surface, has quite bad working environment, and has higher failure rate of communication network and equipment. And the centralized control center is generally positioned at the surface control center and is far from or near to each control subsystem.
As shown in fig. 2, the conventional mine system control architecture method connects all underground control subsystems to a centralized control center through optical fibers, and each system is remotely monitored by a corresponding monitoring host in the centralized control center. This approach has the following disadvantages:
(1) The traditional control mode has no problem when the network and the system are normal, but is difficult to deal with frequent equipment and network faults. And the current mining production exploitation depth is larger and larger, and the physical communication network between each subsystem in the pit and the centralized control center in the pit is longer and longer. When the network communication between the centralized control center and each subsystem in the pit fails, a long time is needed for removing the fault, and each subsystem in the pit is in a runaway state for a long time, so that a large production hidden trouble is caused.
(2) The subsystems cannot be directly accessed and controlled, for example, a worker in a certain subsystem cannot conveniently monitor each subsystem in different places.

Detailed Description
The technical scheme of the invention is described in detail below with reference to the accompanying drawings:
as shown in fig. 1, the centralized control center is in communication connection with each subsystem for remotely monitoring the subsystems.
Specifically, the centralized control center is in communication connection with all the subsystems through the industrial ring network, so that the centralized control center and all the subsystems and the systems are accessed mutually. The network topology of the industrial ring network comprises a core layer, a convergence layer and an access layer. The exchanger of the core layer is two redundancy; the convergence layer exchanger is distributed on the well and under the well to form a plurality of ring networks and is accessed into the core layer exchanger. The exchanger of the access layer forms a plurality of ring-shaped subnets underground and underground, and is accessed upwards to the convergence exchanger. The centralized control center and each subsystem are connected with the exchanger of the access layer. All subsystems and the centralized control center are connected according to the unified definition and the unified architecture of the international standard ISA95, and are communicated and interconnected through the industrial ring network and the access layer communication, and data are shared.
The centralized control center operates an integrated operation platform which is used for collecting data of all subsystems and uniformly controlling the subsystems. The integrated operation platform also has the function of carrying out remote manual control on all subsystems.
When the network communication between the subsystem and the centralized control center is normal, the subsystem at least has two operation modes of local automatic and remote scheduling.
In the local auto mode, the subsystem implements a local control strategy. The local control strategy is generated locally in the subsystem or is generated by the integrated operation platform and then issued to the subsystem.
In a remote scheduling mode, the integrated operation platform sends scheduling control strategies to all subsystems and monitors the operation of all subsystem controls. The scheduling control strategy refers to: under the condition that network communication is normal, the centralized control center collects technological parameters and equipment operation parameters of all subsystems and automatically generates a control strategy consisting of optimal control target values of key parameters of all subsystems. The scheduling control strategy is issued to each subsystem for realizing distributed control. The tasks completed by the subsystems in the well need to be controlled cooperatively in the front-back and left-right directions, and the dispatching control strategy generated by the centralized control center can optimize the production flow.
The subsystem is also provided with a local manual mode, so that workers can conveniently control the subsystem locally.
In the local manual mode and the local automatic mode, the integrated operation platform only collects data for each subsystem without implementing intervention control, and the control is completed locally for the subsystems.
When the network communication between the subsystems and the centralized control center is normal, a worker can also request to temporarily start a horizontal data transmission function between the subsystems on one subsystem (namely, direct communication transmission between the subsystems through an industrial ring network does not pass through the centralized control center) so as to remotely control the other subsystem.
When network communication between the subsystems and the centralized control center fails, a horizontal data transmission function between the subsystems is started, and a worker can remotely control one subsystem based on the horizontal data transmission function.
When the subsystem is remotely controlled through the horizontal data transmission function, the main control subsystem needs to pass through the authority verification of the target subsystem, and the operation record of the remote control is stored in the target subsystem.
It should be noted that, when network communication between the subsystems and the centralized control center fails, each subsystem is automatically switched to operate with a preset local minimum security policy. Because the generation of the scheduling control strategy requires a large amount of data and a great amount of calculation power and control algorithm, each subsystem cannot be completed, when the data is transferred in the underground horizontal direction, only the data related to the currently operated control strategy or the currently operated remote control is transmitted among the subsystems. Each subsystem can automatically select IP for sending shared data of the system required by other systems, so that the cooperative operation of the systems is realized.
Further, after network communication between the subsystems and the centralized control center is restored, horizontal data transmission between the subsystems is closed or a horizontal data transmission function is set to be in a dormant state.
The invention can realize the unified control of the centralized control center on all subsystems, can automatically switch to a horizontal transverse transmission mode when a network fails, and realize the remote control among the subsystems, thereby avoiding the occurrence of safety accidents caused by out-of-control factor systems when the network fails, laying a foundation for unattended operation and improving the monitoring efficiency and the collaborative operation capability of production.
