Embodiment Construction

[0015] A method for online program upgrade of a hydraulic rack controller according to the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] On the basis of the hardware platform of the present invention, such as figure 1 Shown: All hydraulic inter-frame controllers on the working face are connected sequentially through RS-485 inter-frame communication, as shown in figure 2 The internal hardware of the shown hydraulic rack controller includes a main control part and an interface control part. The main control part and the interface control part of the hydraulic rack controller adopt the SPI master-slave communication mode, the interface part is the master, and the master control part is the slave.

[0017] The program flow chart of the specific implementation of the online upgrade function of the hydraulic rack controller program described in the present invention is as follows image 3 As shown, the terminal co...

Abstract

The invention relates to an online program updating method for hydraulic support controllers, in particular to an online program updating method for hydraulic support controllers of an underground fully mechanized mining face of a coal mine. All the hydraulic support controllers on the mining face are sequentially connected by means of RS-485 inter-support communication, and internal hardware of each hydraulic support controller consists of a master control portion and an interface control portion. An end controller selects the number of the hydraulic support controller required to be in program updating operation, a program or an instruction is transmitted to the hydraulic support controller, the program is written into an external RAM (random access memory) after a CPU (central processing unit) of the hydraulic support controller examines the program and the instruction, and then the hydraulic support controller is updated according to the instruction.

Description

technical field [0001] The invention relates to an online upgrading method for an electro-hydraulic controller program, in particular to an online upgrading method for a hydraulic frame controller used in a fully mechanized mining face in a coal mine. Background technique [0002] Fully mechanized mining face hydraulic frame control technology is the key technology to realize coal mining automation, and it is an important way to improve coal mining efficiency and ensure underground safety production. Among them, the timely, convenient and fast update of each controller program of the hydraulic support is one of the key functions to improve the mining efficiency of the coal mine and realize the real unattended working face. [0003] At present, with the rapid development of the coal industry, the research and development of the hydraulic rack control system has also made great progress, and some domestically produced hydraulic rack electro-hydraulic control systems have been ...
