Therefore, if can simplify control program, reducing breakdown rate, and then reduce the maintenance rate of equipment, improve the working time and the operating efficiency of shield machine, has been a urgent problem.
Summary of the invention
In order to solve the deficiency in the above-mentioned technology, the utility model provides a kind of novel control model of shield machine control system, can be good at reducing breakdown rate, reduces the equipment changer time, ensures the working time and the operating efficiency of shield structure.
The purpose of this utility model is achieved in that
A kind of shield machine control system, it is the programmable control system of shield machine, comprise man-machine interface 1, main programmable logic controller 3 and distributed site 5, it is characterized in that: man-machine interface 1 is connected with main programmable logic controller 3 by network 2, and main programmable logic controller 3 is connected with distributed site 5 by network 4.
Man-machine interface 1 is distributed with one or more computer in parallel and that be connected with network 2 and forms.
Distributed site 5 can be distributed I/O system, also can be the distribution type programmable controller.
Network 2 is international network with network 4, can be consolidated network, also can be two kinds of networks of different type that linked together by main programmable logic controller 3.
Beneficial effect: the utility model changes control system into distributed control model by existing focus control mode.Distribution situation according to each system of shield structure, control system is distributed in the position that concentrate relatively at the control point, promptly make things convenient for the control of control system, also make things convenient for the investigation of fault and reduce fault rate, reduced the changer time of equipment electrical system more greatly, thereby reduced the operation cost of project, simplified the operation, maintaining is convenient.
Description of drawings
Figure is a composition structural representation of the present utility model;
Among the figure be: man-machine interface 1, network 2, main programmable logic controller 3, network 4, distributed site 5:
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of shield machine control system, it is the programmable control system of shield machine, comprise man-machine interface 1, main programmable logic controller 3 and distributed site 5, it is characterized in that: man-machine interface 1 is connected with main programmable logic controller 3 by network 2, and main programmable logic controller 3 is connected with distributed site 5 by network 4.
