Abstract
The utility model provides an intelligent protection system of a belt conveyor. The intelligent protection system comprises a node control device arranged on each node of the belt conveyor. Each node control device is connected with a main controller via a CAN bus; the output end of the main controller is connected with the belt conveyor; each node control device comprises a DSP processor; the input end of the DSP processor is respectively connected with a detection device; the output end of the DSP processor is connected with the main controller; and each node control device is interactively connected with each other via a CAN driver. The intelligent protection system of belt conveyor can both protect and control the belt conveyor, so an original condition of separated control and protection is reformed; and detection information of the system can be shared, so work efficiency of the belt conveyor is increased and safe production is guaranteed.
Description
Technical field
The utility model relates to belt conveyer, is specifically related to a kind of intelligent protection system of belt conveyer.
Background technology
Belt conveyer is widely used among the Coal Transport system of Modern coal mines as a kind of successional material transport equipment.Can belt conveyer be stablized, working safely has directly determined the coal production in colliery, but often there are various faults in belt conveyer, skid in transportation, sideslip, vertically tear, broken belt etc.
When normal operation, for many motor driving systems, under same rotating speed, due to the difference of motor parameter, can cause electrical motor carrying overbalance, make indivedual heavily loaded motor temperatures too high.The difference that simultaneously also makes load-transfer device pass through cylinder tension force strengthens, and affects load-transfer device service life.The confidential system-wide of realizing of belt conveying is coordinated to control, and first will solve the long apart from transmission, comprehensive of each autonomous system detection signal and control signal.And communication facilities is participated in the closed loop control of system directly, so system has higher requirements to rapidity and the reliability of communication.The method of inspection of status signal and the reasonableness of tranmission techniques, directly affect complexity and investment that belt conveyer signal cable lays.
The load-transfer device that the utility model occurs Operation of Belt Conveyor is overrun, transport belt slippery, over current of motor, oil temperature are crossed outside high parameter real time monitoring; the faults such as the sideslip that also should be able to occur completely belt conveyer, carrying roller temperature, coal piling, broken belt, tearing tape realize monitoring and protection, and can report corresponding fault type and position of fault.
Utility model content
The utility model will solve above-mentioned deficiency exactly, and a kind of intelligent protection system of belt conveyer is provided, and reaches belt conveyer is realized and being controlled and protection organic integration, improves its work efficiency, guarantees safety in production.
In order to reach above-mentioned effect, the utility model provides a kind of intelligent protection system of belt conveyer, comprise the node control device of being located at each node of belt conveyer, each node control device is all connected with master controller by CAN bus, and the mouth of described master controller is connected with belt conveyer; Described node control device comprises dsp processor, and the input end of described dsp processor is connected with detecting device respectively, and its mouth is connected with master controller; Between described each node control device, by CAN actuator is interactive, connect.
The preferred version of such scheme is that the mouth of described detecting device is connected with the input end of dsp processor by signal amplifier.
Further, between described dsp processor and CAN actuator, be provided with photoisolator.
Further, described detecting device comprises switch sensor, coal site sensor, misalignment sensor, speed sensor, temperature sensor and Smoke Sensor.
The utility model by the protection of belt conveyer, control integration together, changes and originally controlled, protects separated situation, and the detection information of system is shared, and has improved the work efficiency of belt conveyer, for safety in production provides assurance.
The radical function of this protection system has:
(1) slipping protection: in belt conveyer working process, asynchronous with the speed of load-transfer device due to the speed of driving drum, both produce relative sliding, produces skidding.Skid and can make cylinder surface temperature sharply raise, cause that load-transfer device catches fire, when serious, cause coal dust and gas explosion.This protection system Negotiation speed sensor detects respectively the speed of cylinder and load-transfer device, judges that both have bias free at speed, can carry out slipping protection.
(2) sideslip protection: at the edge-on roller of load-transfer device both sides mounted in pairs; when load-transfer device generation sideslip; band edge is encountered edge-on roller, makes its lever when rotating, depress misalignment sensor, and misalignment sensor sends to master controller points driving for belt conveyor to shut down this signal and overhauls.
(3) overspeed protection: by being arranged on the real-time speed of the speed sensor detection load-transfer device on load-transfer device, judge whether hypervelocity.
(4) smog protection: when Smoke Sensor detects load-transfer device because of reason generation smog such as frictions, signal is transferred to master controller, cuts off motor power, connect automatic water system.
(5) coal piling protection: when coal bunker is bought securities with all one's capital, coal site sensor sends signal, automatic train stop.
(6) temperature protection: temperature sensor is arranged on cylinder, when load-transfer device and roll friction make temperature over-range, shuts down the temperature protection effect of playing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural principle block diagram (only draw a node control device schematic diagram, other node control device herewith).
The specific embodiment
As shown in Figure 1, the utility model provides a kind of intelligent protection system of belt conveyer, comprise the node control device of being located at each node of belt conveyer, each node control device is all connected with master controller 3 by CAN bus, and the mouth of described master controller 3 is connected with belt conveyer 4; Described first node control setup 1 comprises dsp processor 1-8, and the input end of described dsp processor 1-8 is connected with detecting device respectively by signal amplifier 1-7, and its mouth is connected with master controller 3; The mouth of dsp processor 1-8 is by photoisolator 1-9 and 2 communications of CAN actuator; Between each node control device, by CAN actuator 2 is interactive, connect.
Further, described detecting device comprises switch sensor 1-1, coal site sensor 1-2, misalignment sensor 1-3, speed sensor 1-4, temperature sensor 1-5 and Smoke Sensor 1-6.
The structure of other node control device is with first node control setup.
