Abstract
The utility model relates to an electric control system of a CAN bus modularized coal mining machine, which comprises a main control module, a data acquisition module, an instruction execution module and a data display module, wherein each module is provided with a communication interface unit, and the communication interface unit of the main control module is connected with the communication interface units of the other modules through a CAN bus. The electric control system has simple structure and high reliability. Modularized design idea is adopted, and all the modules are independently designed and debugged. When one module is in the event of failure, the failure module can be found out in time, the failure time is reduced, and the production rate is improved. The advanced CAN bus is adopted. The CAN bus has the advantages of high communication speed, good openness, short message, strong correction capability, simple control, strong extended capability, low application cost and the like. The modularized design is adopted, the expandability of the system is good, the modules are independent with each other, when the system is required to add new functions, only a module with corresponding functions is required to be designed and directly hung on the bus, the whole system is not required to be redesigned, and unnecessary repetitive work is reduced.
Description
Technical field
The utility model relates to the electric-control system in electric automatization field, particularly relates to a kind of electric-control system that is used for control coalcutter under the coal mine.
Background technology
The coalcutter electric-control system that use at present in the colliery is with single-chip microcomputer and the PLC centralized control system as core, in recent years part unit to begin to explore with the industrial computer be the centralized control system of core.Centralized control, all signals all will be connected to controller by cable, and it is crowded to cause the machine inner cable to arrange, and cabling is various, and is difficult in maintenance.The PLC anti-vibrating and impact is indifferent, bad adaptability under coal mine.The PLC that function is strong is again often structurally because its versatility is compact inadequately.Existing single-chip microcomputer centralized control system is subjected to the restriction of single-chip microcomputer performance and resources of chip, and the function of realization is too simple, is difficult to the complicated day by day and senior control requirement of competent modern coalcutter.
The utility model content
The purpose of this utility model is that above-mentioned shortcoming of the prior art is improved, provide a kind of automatically controlled based on CAN bus module coalcutter, each module links together by 5 core shielded cables, each module is carried out different functions, finishes jointly to the monitoring of coalcutter each several part running parameter with to coalcutter and controls.
The technical solution of the utility model is: a kind of CAN bus module coalcutter electric-control system, comprise main control module, data acquisition module, instruction execution module and data disaply moudle, described each module is provided with communication interface unit, and the communication interface unit of main control module joins by the communication interface unit of CAN bus and all the other each modules.
Preferably: described data acquisition module comprises analogue collection module and remote control receiver module.
Preferably: described analogue collection module comprises voltage acquisition module and temperature collect module.
Preferably: described instruction execution module is a relay output module.
Preferably: described CAN bus is the cable of five cores shielding.
The beneficial effects of the utility model are: native system is simple in structure, the reliability height.Adopt the passage of CAN bus as message exchange, between each module wiring simple, only need 5 heart yearns to get final product.Adopt modular design method, each module designs separately, debugging.When certain module breaks down, can in time find out malfunctioning module, reduce fault-time, boost productivity.Adopt advanced CAN bus.Characteristics such as the CAN bus has the traffic rate height, opening is good, message short, error correcting capability is strong and control is simple, extended capability is strong, application cost is low.Adopt modular design, system extension is good, each module is separate, when system need increase new function, only need design that the module of corresponding function is arranged, directly hang on the bus and get final product, do not need total system is redesigned, reduce unnecessary repeated labor.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model:
A kind of CAN bus module coalcutter electric-control system, comprise main control module, data acquisition module, instruction execution module and data disaply moudle, described each module is provided with communication interface unit, and the communication interface unit of main control module joins by the communication interface unit of CAN bus and all the other each modules.Described data acquisition module comprises analogue collection module and remote control receiver module.Described analogue collection module comprises voltage acquisition module and temperature collect module.Described instruction execution module is a relay output module.Described CAN bus is the cable of five cores shielding.
Main control module: adopt EPEC as the control core, behind the CAN signal execution internal processes that receives, send control command on the CAN bus, after relay output module is isolated, send to each control module again, realize the control of coalcutter electrical system.
Communication interface modules is responsible for the data link and the transmitting-receiving of CAN bus, is the hinge of The whole control system.
The remote control receiver module is the radiofrequency signal from remote transmitter that will receive, behind the signal condition filtering interference signals, send into the CAN bus transceiver after being converted to digital signal, data are sent on the CAN bus, and be sent to the main control module processing by the CAN bus transceiver.
Analogue collection module: component voltage, two kinds of acquisition modules of temperature, though the function of two kinds of modules is incomplete same, adopt with a kind of design proposal for same section.Each module serves as the control core with single-chip microcomputer PIC18F4680 all, adds that A/D change-over circuit MCP3208, the isolation of CAN bus M1201BR, CAN bus transceiver MCP2551 form.
Relay output module is the output control module that the control signal (CAN) that main control module sends is converted to the switching value signal.
It is displaing core that display module adopts industrial computer, by configuration software display system is carried out configuration, show by main control unit control monitored picture, and be the important component part of coalcutter supervisory system.
