Embodiment 1

[0040] Such as Figure 1 to Figure 4 Commonly shown, a remote control type hydraulic support communication system includes multiple hydraulic supports, each hydraulic support is provided with a support controller, the support controller is provided with a first communication unit, and the first communication unit includes at least two wired Communication module and at least two wireless communication modules, each communication module of the first communication unit can carry out the communication between the support controllers on all hydraulic supports, forming multiple wired or wireless communication loops; the system also includes support remote control, support The remote controller is provided with a second communication unit. The second communication unit includes at least two wireless communication modules. The second communication unit and the first communication unit form at least two wireless communication loops for binding to establish a wireless connection to trans...

Embodiment 2

[0069] A remote-controlled hydraulic support communication method, based on the remote-controlled hydraulic support communication system in Embodiment 1;

[0070] Described method comprises the following steps:

[0071] Step 1. The support controllers on all hydraulic supports communicate through the wired communication module;

[0072] Step 2: The stand remote controller determines the stand controller closest to it, and binds with the stand controller within a preset time to establish a wireless connection;

[0073] Step 3: Enter the locked state under the control of the bound bracket controller;

[0074] Step 4. After binding, the bracket remote controller transmits data through the wireless communication circuit between the second communication unit and the first communication unit;

[0075] Step 5. The bound support controller transmits data to the selected support controller of the hydraulic support through the wired communication module. When the data transmission fai...

Abstract

The invention discloses a remote control type hydraulic bracket communication system and a remote control type hydraulic bracket communication method. The remote control type hydraulic bracket communication system comprises a plurality of hydraulic brackets and a bracket remote controller, wherein each hydraulic bracket is provided with a bracket controller, each bracket controller is provided with a first communication unit, each first communication unit comprises at least two wired communication modules and two wireless communication modules, each bracket remote controller is provided with asecond communication unit, and each second communication unit at least comprises two wireless communication modules. The remote control type hydraulic bracket communication method comprises the stepsthat each bracket remote controller and the corresponding bracket controller are bound through using a wireless communication loop to establish connection, data are transmitted to the bracket controller through another wireless communication loop, the bracket controller transmits the data to the corresponding bracket controller through a wired communication loop, and hydraulic bracket control isachieved. Due to the fact that at least two wireless communication loops are arranged between the first communication unit and the second communication unit, and multiple communication loops are arranged between the bracket controllers, reliable communication can be achieved, and the operation reliability of the whole system is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic support control, in particular to a remote control type hydraulic support communication system and method. Background technique [0002] The electro-hydraulic control system of the hydraulic support of the fully mechanized mining face is the key technology for the automatic control of the coal mine fully mechanized mining face, especially the electro-hydraulic control system of the hydraulic support is a communication network system composed of multiple support controllers connected to each other in the working face. The network unit is generally Between 100 and 250, due to the harsh production environment of the underground working face, large dust, high temperature, and high humidity, continuous spraying is required during the production process, which is a great challenge to the protection of electrical equipment on the working face. Conventional brackets Each frame of the electro-hydraulic c...
