Abstract
The invention provides an intelligent protection system of a belt conveyor, which includes node control devices arranged at nodes of the belt conveyor, wherein all the node control devices are connected with a master controller through a CAN bus; the output end of the master controller is connected with the belt conveyor; each node control device includes a DSP; the input ends of the DSPs are connected with a detection device respectively, and the output ends of the DSPs are connected with the master controller; all the node control devices are interactively connected through a CAN driver. The intelligent protection system integrates the protection and control of the belt conveyor, changes the original situation that the control and protection are separated, enables detection information of the system to be shared, improves the working efficiency of the belt conveyor, and guarantees the safety production.
Description
Technical field
The present invention relates to belt conveyer, be 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 has safely directly determined the coal production in colliery, but various faults often occur in belt conveyer in transportation, skid, 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 also makes simultaneously load-transfer device pass through cylinder tension force strengthens, and affects load-transfer device service life.Belt conveying is confidential realizes that system-wide coordinates to control, and the long distance that at first will solve each autonomous system detection signal and control signal transmits, comprehensive.And communication facilities is participated in the closed loop control of system directly, so system has higher requirements to rapidity and the reliability of communicating by letter.The method of inspection of status signal and the reasonableness of tranmission techniques, directly affect complexity and investment that the belt conveyer signal cable lays.
The present invention to the load-transfer device that Operation of Belt Conveyor occurs overrun, transport belt slippery, over current of motor, oil temperature cross 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.
Summary of the invention
The present invention will solve above-mentioned deficiency exactly, and a kind of intelligent protection system of belt conveyer is provided, and reaches belt conveyer is realized controlling and the protection organic integration, improves its work efficiency, guarantees safety in production.
In order to reach above-mentioned effect, the invention 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 all is connected with master controller by the 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; Connect by the CAN actuator is interactive between described each node control device.
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, be provided with photoisolator between described dsp processor and CAN actuator.
Further, described detecting device comprises switch sensor, coal site sensor, misalignment sensor, speed sensor, temperature sensor and Smoke Sensor.
The present invention with the protection of belt conveyer, control integration together, changes the situation of originally controlling, protect separation, 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 the belt conveyer working process, because the speed of the speed of driving drum and load-transfer device is asynchronous, both produce relative sliding, produce skidding.Skid the cylinder surface temperature is sharply raise, cause that load-transfer device catches fire, cause coal dust and gas explosion when serious.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 depress misalignment sensor when rotating, and misalignment sensor sends to the 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 the reasons such as friction generation smog, signal is transferred to master controller, cuts off motor power, connect automatic water system.
(5) coal piling protection: when coal bunker was bought securities with all one's capital, coal site sensor sent 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.

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural principle block diagram of the present invention (only draw a node control device schematic diagram, other node control device herewith).
The specific embodiment
As shown in Figure 1, the invention 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 all is connected with master controller 3 by the 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; Connect by CAN actuator 2 is interactive between each node control device.
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 the first node control setup.
