Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] The addressing system for the mine hydraulic support controller is characterized in that: the system includes an addressing unit installed on each mine hydraulic support controller, a CAN bus and a general controller, and the addressing unit passes CAN The bus is connected sequentially, and the addressing units are respectively connected to the general controller. The addressing unit includes a pulse generator, a pulse counter and a relay. The pulse generator is connected to the pulse counter through the relay. The bus is connected to the pulse counter on the believed addressing unit.

[0025] In order to realize that the master controller can accurately control each mine hydraulic support, the master controller needs each mine hydraulic support controller to assign address information, and the master controller identifies the mine hydraulic support controller th...

Abstract

An addressing system for controller of hydraulic support for mine comprises addressing units mounted on each controller of hydraulic support for mine, a CAN (controller area network) bus and a master controller, wherein the addressing units are in sequential connection via the CAN bus and connected with the master controller. Each addressing unit includes a pulse generator, a pulse counter and a relay. An addressing method for controller of hydraulic support for mine comprises (1) disconnecting all relays; (2) determining the first addressing unit; (3) determining an adjacent addressing unit; (6) determining the last addressing unit; and (7) allowing the master controller to send out an addressing termination instruction to accomplish the addressing process. The inventive addressing system and addressing method can assign an address to all controllers of hydraulic supports for mine connected to the master controller, effectively improve addressing efficiency and reduce the error rate caused by manual addressing.

Description

technical field [0001] The invention relates to an addressing system and an addressing method thereof, in particular to a system and an addressing method for addressing a mine hydraulic support controller. Background technique [0002] The hydraulic support is one of the main equipment of the comprehensive mechanized coal mining face, and it is distributed on the entire working face. There may be as many as 252 hydraulic supports installed on each working face, and a set of hydraulic support controller is installed on each hydraulic support. In order to control the work of this station or the adjacent frame, in order to realize the automatic control of the whole working surface, the controllers are connected with the CAN bus standard cable to form a huge support control system. [0003] Since each work surface is composed of tens or even hundreds of controllers, and each controller has its own frame address as the factory value when it leaves the factory, so there will be ma...
