Detailed Description
The present invention will be described in further detail with reference to the following examples:
the invention provides a remote control hydraulic system of a distributed group system of a rail-beam rolling mill set, which aims at the problems of large hydraulic system of large metallurgical equipment, wide occupied area of an underground oil tank, complicated pipeline connection, large required power, bad field control operation environment and the like. As shown in fig. 1, the system disassembles a conventional overall bulky hydraulic system into a plurality of independent rolling mill units, and each rolling mill unit is distributed in the whole work production line according to work requirements. As shown in fig. 2, each rolling mill unit has a relatively independent unit processor for controlling a set of independent pump-valve-hydraulic cylinder system, so as to control the hydraulic cylinders in the unit. The unit processor of each rolling mill unit is connected with a group control unit processor in the factory building through buses such as CANBUS, and the unit processors of the rolling mill units receive the instructions of the group control unit processor and control the action of the hydraulic cylinders in the unit. The group unit control processor is connected with a remote monitoring center through buses such as CANBUS and the like, and the remote monitoring center monitors the field working condition of a working area in real time and has the highest command control right. It should be noted that: in fig. 2, the solenoid valves 4, the pilot operated check valves 5, the hydraulic cylinders 6, the displacement sensors 7 and the pressure sensors 8 respectively represent all the solenoid valves, the pilot operated check valves, the hydraulic cylinders and the sensors in each rolling mill unit.
As shown in fig. 3, after the unit processors of each rolling mill unit receive the actuating signals from the group unit processors, the unit processors of the rolling mill units send out instructions, the motor 3 is started, the electromagnetic valve 4 is switched, and the piston rod of the hydraulic cylinder 6 moves. Data collected by a displacement sensor 7 and a pressure sensor 8 in the rolling mill unit are fed back to a unit processor, and the unit processor judges whether each hydraulic cylinder 6 in the rolling mill unit meets the working requirement or not. If the working requirement is met, the unit processor feeds back a working in-place signal to the group unit controller, and the group control unit processor sends a working instruction to the next rolling mill unit. If the working requirement is not met, the unit processor will continue to adjust the action of the hydraulic cylinder 6 in the unit. Therefore, the group unit control processor can simultaneously or sequentially send instructions to the unit processors of the plurality of rolling mill units according to the work production flow to meet the production work.
In addition, the group control unit processor is also connected with the remote monitoring center through a CANBUS bus, and the group control unit processor can transmit the real-time condition of each rolling mill unit actuating unit to the remote monitoring center. The remote monitoring center has the highest system control right, when the remote monitoring center does not send out an instruction, the group control unit processor can control the unit processor of each rolling mill unit to work according to a pre-designed program, and only monitored data need to be transmitted back to the remote monitoring center. When the remote monitoring center sends an instruction to the group control unit processor, the control right of the system is transferred to the remote monitoring center, the group system unit processor is equivalent to a signal transfer station, and the remote monitoring center directly controls the unit processor of each rolling mill unit to act. The priority of the control right is from high to low: the system comprises a remote monitoring center, a group control unit processor and a unit processor.
