Accompanying drawing explanation
Fig. 1 is the utility model structure principle chart.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, this protection control device of coal mine belt conveyer, comprise mine explosion-suppression and intrinsic safety type PLC case 1, the periphery of described mine explosion-suppression and intrinsic safety type PLC case 1 is connected with respectively Mine-used I. S operator's station 2, mine explosion-suppression escope 3, flame-proof mine AC converter 4, motor monitoring device 5, gauging device 6, tightening device 7 and a plurality of mine flameproof and intrinsic safety type communicating acousto-optic signal 8, described motor monitoring device 5 is connected with described flame-proof mine AC converter 4, the guard signal generating means of belt conveyer is connected with described mine flameproof and intrinsic safety type communicating acousto-optic signal 8, the guard signal generating means of described belt conveyer comprises tears sensor 81, misalignment sensor 82 and emergency stop switch 83.The alarm signal generator means of belt conveyer is connected with described mine explosion-suppression and intrinsic safety type PLC case 1, and the alarm signal generator means of described belt conveyer comprises Smoke Sensor 11, temperature sensor 12, speed sensor 13, coal site sensor 14 and watering electromagnetic valve 15.
Described mine explosion-suppression and intrinsic safety type PLC case 1 is set to many, between every two, by Profibus-DP communication, connects, so relatively independent between PLC case, is coupled to each other again, forms a set of control system flexibly.
The utility model in actual use, described mine flameproof and intrinsic safety type communicating acousto-optic signal 8 is connected with mine explosion-suppression and intrinsic safety type PLC case 1 by CAN bus mode, mine explosion-suppression and intrinsic safety type PLC case 1 receives the flame-proof mine AC converter 4 being attached thereto on the one hand, mine flameproof and intrinsic safety type communicating acousto-optic signal 8, the job information of the equipment such as the alarm signal generator means of belt conveyer and motor monitoring device 5, to control each device action, and according to the output frequency of the weight control flame-proof mine AC converter 4 of goods on the conveyer of gauging device 6 meterings, control the power of motor output, to save traffic cost, on the other hand, receive working parameter and controlled condition that Mine-used I.
