Hydraulic support remote control method and system

Abstract

The invention provides a hydraulic support remote control method and a system. The method comprises the steps as follows: transmitting command information through an emitter; receiving the command information through a receiver which has the same wireless communication frequency as the emitter; decoding the received command information through the receiver, and judging whether the ID number of a controller in the received command information is in the preset ID receiving range, if so, storing the decoded command information, if not, abandoning the command information. With the adoption of the hydraulic support remote control method and the system, the problem of same frequency interference can be effectively avoided; and the operation is convenient and safe.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a hydraulic support remote control method and system. Background technique [0002] At present, the use of remote controllers in coal mining is not very common. Under the mine, the use of the remote control is also limited to a single controlled object, such as coal mining machines, roadheaders and other equipment, and is rarely used for remote control of hydraulic supports. In occasions where short-distance multiple objects need to be remotely controlled at the same time, time-division multiplexing is often used to control in turn. It is not true that multiple remote controls perform remote control at the same time. This remote control method is not suitable for multi-machine control of hydraulic supports. Normally, when operating the hydraulic support controller, it must be ensured that the controlled support is within a safe sight distance. Therefore, if it is nece...

Problems solved by technology

First, when adjacent transmitters send instruction information at the same time, there will be co-channel interference between the two. When one transmitter is working, if the other transmitter has an instruction to send, it must wait for the channel to be released before proceeding. When there are multiple operators operating at the same time, this interference is more obvious and seriously affects normal operation

Second, in the case where sub-regional operations are required, the usual practice is to achieve remote control isolation between regions by adjusting the RF power of the transmitter. This method is only when the transmitters are far away from each other, and the respective RF signal strengths will not affect It can only be realized when the other party is remotely controlled, and in the case of partition control of the hydraulic support, in order to ensure the safety of the operation, the distance between the transmitters is usually relatively close, and the radio frequency signals cannot be isolated from each other.

Third, although the address of the target controller is included in the instruction information order, it is inevitable that the negligence of the operator will cause cross-regional operations and cross-operations, causing safety problems
