Embodiment Construction

[0021] A hydraulic support control method, such as figure 1 shown, including the following steps:

[0022] Step S110: receiving the control instruction through the main controller, and controlling the corresponding hydraulic support to perform corresponding actions according to the control instruction. The control instruction can be adjusted by the action that actually needs to be performed. Specifically, each hydraulic support is provided with a controller and a push rod, the push rod is connected to the chute through a joint, and the controller receives instructions to control the push rod to move. In this embodiment, the controller on one of the hydraulic supports can be used as the main controller to receive the control instructions input by the staff, and correspondingly control the relevant hydraulic supports, for example, control adjacent or spaced hydraulic supports to perform corresponding actions. It can be understood that a single controller may also be used as th...

Abstract

The invention relates to a hydraulic support control method and system. A master controller receives a control instruction and controls a corresponding hydraulic support according to the control instruction to execute corresponding movements; the master controller sends the control instruction to a slave controller in the corresponding hydraulic support. The corresponding hydraulic support controls a next hydraulic support according to the control instruction to execute corresponding movements and sends the control instruction to a slave controller in the next hydraulic support, related hydraulic supports are controlled according to the steps, and then the control instruction is sent to a slave controller of the next hydraulic support till the related hydraulic supports all complete corresponding movements. The master controller controls the corresponding hydraulic support to execute corresponding movements and sends the control instruction to the slave controller of the corresponding hydraulic support, then the slave controller can repeatedly execute all the single movements executed by the master controller, and then the work efficiency and the automatic hydraulic support control level are improved.

Description

technical field [0001] The invention relates to the technical field of scraper conveyors, in particular to a hydraulic support control method and system. Background technique [0002] The hydraulic support is connected to the chute of the scraper conveyor through the connecting head of the push rod, and the controller on the hydraulic support controls the forward and backward of the chute by controlling the extension and retraction length of the push rod. [0003] The traditional hydraulic support operation mode is that the workers control the movement of the support through the support controller, specifically, the single-action control mode is used to control the movement of adjacent or partitioned supports. For example, when performing the action of pulling the frame, it is necessary to perform a series of actions such as lowering the frame (there may be spray at the same time), pulling the frame (there may be spray or side protection at the same time), raising the frame,...
