Abstract
A power line carrier communication-based electro-hydraulic control system is provided. The power line carrier communication-based electro-hydraulic control system includes a power supplying device, power lines, an information coupling device and working surface apparatuses, wherein the power supplying device is connected with the working surface apparatuses through the power lines; the information coupling device is arranged on the power lines and includes a filter and a coupling capacitor; and each working surface apparatus comprises a controller and an information receiving apparatus, wherein the information receiving device is connected with the power lines and the controller. The power line carrier communication-based electro-hydraulic control system of the utility model has the advantages of simple structure and reliable work. With the power line carrier communication-based electro-hydraulic control system adopted, wiring space of a communication system can be saved. According to the power line carrier communication-based electro-hydraulic control system, arrangement is realized through adopting line distributors, so that one information coupling device can be corresponding to a plurality of working surface apparatuses, and therefore, reconstruction cost and difficulty can be decreased. The power line carrier communication-based electro-hydraulic control system is suitable for being widely applied in underground working surfaces.
Description
Technical field
The utility model relates to a kind of working face electrohydraulic control system, relates in particular to a kind of electrohydraulic control system that uses electric line carrier communication.
Background technology
Along with the raising of coal working face automaticity, the requirement of working face communication is also improved thereupon, as communication between the communication between the communication of the communication between working face staff, working face staff and ground control cabinet, working face staff and underground equipment, ground control cabinet and underground equipment etc.Existing communication is conventionally by drawing a special communication line to realize, but it is more loaded down with trivial details that this special communication line arranges, safeguard inconvenience, occupy original with regard to narrow and small space, down-hole, and communication is wherein easy to be interfered, have a strong impact on the effect of communication.
Therefore, a kind of down-hole information transmission system that can realize easily communication is badly in need of in this area.
Utility model content
For the problems referred to above, the utility model proposes a kind of electrohydraulic control system based on electric line carrier communication, comprise electric supply installation, power line, information coupling device, working face equipment, described electric supply installation connects described working face equipment by described power line; Described information coupling device is arranged on described power line, comprises filter and coupling capacitor; Described working face equipment comprises controller and information receiver, and described information receiver connects described power line and described controller.
Preferred described working face equipment comprises one or more in working surface hydraulic support, scratch board conveyor, coal-winning machine.
Preferred described working face equipment has multiple.
On preferred described power line, be provided with deconcentrator.
The multiple working face equipments of preferred described control unit control.
The utility model has the advantage of: simple in structure, reliable operation, the arrangement space of having saved communication system; Employing deconcentrator is arranged, has realized the corresponding multiple working face equipments of an information coupling device, has saved transformation spending and difficulty, is applicable to the popularization on a large scale of mining face under mine.
Brief description of the drawings
The structure diagram that accompanying drawing 1 is electrohydraulic control system described in the utility model;
Accompanying drawing 2 is for using the system johning knot composition of the multiple hydraulic supports of electrohydraulic control system control based on electric line carrier communication.
Embodiment
Below in conjunction with accompanying drawing, the electrohydraulic control system based on electric line carrier communication described in the utility model is described in detail.Referring to accompanying drawing 1, based on the electrohydraulic control system of electric line carrier communication, comprise electric supply installation, power line, information coupling device and 4 working face equipments, working face equipment comprises 2 hydraulic supports, 1 coal-winning machine and 1 scratch board conveyor, in actual production, more or less working face equipment also can be set as required.Electric supply installation is generally industrial power supply, is responsible for to working face equipment power supply, and it connects each working face equipment by power line, in the situation that having multiple working face equipment, can deconcentrator be set in power line stage casing and carry out separated time; Information coupling device is arranged on the upper end on power line and in deconcentrator, comprises filter and coupling capacitor, for required control information is coupled on power line and is transmitted.On working face equipment, comprise controller and information receiver, information receiver one end connects power line, the other end connects controller, controller is generally used for controls the normal operation of equipment separately, be responsible for herein control information receiving system and obtain the information of transmission from power line, and judge whether it is the information for this equipment, if, carry out next step operation according to the content of information, as support moves frame etc.
Referring to accompanying drawing 2, taking to the control of hydraulic support as example further illustrates system of the present utility model.The control unit of each hydraulic support is connected on power line, one group of 3 hydraulic support of a control unit control, and control device comprises transducer, electromagnetically operated valve and the supervision video camera of each hydraulic support.By the direct control information transmission of power line and data, control unit is receiving the instructions of according to circumstances controlling corresponding device after information and move the face of finishing the work.
The above; it is only preferably embodiment of the utility model patent; but the protection range of the utility model patent is not limited to this; any be familiar with those skilled in the art the utility model patent disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in the protection range of the utility model patent.
