Description

Hydraulic support remote control thereof and system
Technical field
The present invention relates to the human-computer interaction field, particularly relate to a kind of hydraulic support remote control thereof and system.
Background technology
At present, the use of remote controller in Coal mine excavation also is not very general.Under mine, the use of remote controller also is to only limit to single controlled device, and such as coal-winning machine, the equipment such as development machine are rarely used in the remote control of hydraulic support.Carrying out simultaneously remote control of a plurality of objects of short distance occasion at needs, adopt time division multiplexing mode to take turns current control more, is not truly, and many remote controllers carry out straighforward operation simultaneously.This remote control mode not too is suitable for the multimachine control of hydraulic support.Generally, when hydraulic bracket controller behaviour is done, must guarantee that controlled support is in safe sight distance.Therefore, to many hydraulic supporting controller grouping remote controls, then the distance between adjacent packets is relatively near such as need, in the case, such as simultaneously remote control of need, then can only carry out timesharing wheel current control, has a strong impact on operating efficiency.In addition, in using two or many remote controllers and many receiver corporation remote control modes, every receiver is all resolved the control information that all receive, and does not do selective parsing.
Remote controller adopts single channel to carry out the command information transmission more on the market, is carrying out there are three problems in the subregion control situation.First, when adjacent transmitter sends command information simultaneously, the co-channel interference phenomenon can occur between the two, when a transmitter job, another transmitter sends if any instruction, must wait for that then channel is released just and can carries out, when having several operators to operate simultaneously, this interference is more obvious, has a strong impact on normal operating.Second, carry out subregion operation occasion at needs, usually way just reaches interregional remote control isolation by the radio-frequency power of adjusting transmitter, this method is just distant apart each other at transmitter, RF signal strength separately can not have influence in the situation of the other side's remote control and could realize, and hydraulic support is being carried out in the subregion control situation, is the safety that guarantees operation, usually close together between transmitter can't be accomplished being isolated from each other of radiofrequency signal.The 3rd, though include the address of the Control of the aim device in the command information order, because operator's carelessness causes transregional operation, interlace operation causes safety problem unavoidably.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic support remote control thereof and system, antijamming capability is strong, handling safety.
Purpose of the present invention is achieved by the following scheme:
A kind of hydraulic support remote control thereof comprises the steps:
Send command information by transmitter;
The receiver that has the same wireless communication frequency with described transmitter receives described command information;
Described receiver is decoded to the command information that receives, and judges that the controller ID numbering that comprises in the command information receive is whether in default ID range of receiving.
A kind of hydraulic support remote control system comprises:
Transmitter comprises the first Transmit Receive Unit, and described the first Transmit Receive Unit is used for sending command information;
Has the receiver of same wireless communication frequency with described transmitter, described receiver comprises the second Transmit Receive Unit, decoding unit, control module, described the second Transmit Receive Unit is used for after receiving described command information, the command information that receives is transmitted to described decoding unit, described decoding unit is decoded to received command information, described control module is used for judging that controller ID numbering that decoded command information comprises is whether in described ID range of receiving, if, then preserve decoded command information, if not, then abandon described command information.
Scheme according to the invention described above, receiver can only receive the command information of the transmitter transmission that has with it the same wireless communication frequency, then when operator's division operation hydraulic support, only needing in advance, corresponding receiver and the transmitter in same controlled district is set to same wireless telecommunications frequency, and the wireless telecommunications set of frequency in each controlled district is different wireless telecommunications frequency, just can effectively avoid problem of co-channel interference, in addition, after receiver receives command information, the command information that receives is decoded, judge that the controller ID numbering that comprises in the command information receive is whether in the ID of correspondence range of receiving, if, then decoded command information is preserved, if not, then abandon described command information, by this command information is selectively preserved, can prevent the transregional operation that causes because of operator's carelessness, interlace operation etc.The present invention has avoided the problems such as co-channel interference phenomenon effectively, simultaneously easy to operate, safety.
