The specific embodiment
The structured flowchart of the mining scraper transport control system that Fig. 1 provides for the utility model embodiment, the utility model embodiment provides a kind of mining scraper transport control system, comprise transport plane 1 or elevating conveyor 2, underground hauling of coal relies on transport tape to transmit usually, the mining scraper transport control system that the present embodiment provides, be provided with transport plane 1 or elevating conveyor 2, also can comprise simultaneously transport plane 1 and elevating conveyor 2, particularly, can comprise an elevating conveyor 2 and three transport planes 1, transport plane 1 is respectively the transport plane 1 that is arranged on the transport tape afterbody, be arranged on the transport plane 1 parallel with transport tape and the transport plane 1 vertical with transport tape that the transport tape head is set of transport tape head.Above-mentioned transport plane 1 or elevating conveyor 2 comprise variable-frequency motor, and variable-frequency motor comprises frequency converter 3 and motor main body 4, and the frequency conversion mouth of frequency converter 3 links to each other with the frequency conversion input end of motor main body 4; Above-mentioned control system comprises that also the control output end of this master control set 5 links to each other with the control input end of frequency converter 3 for the master control set 5 that sends the frequency conversion instruction to frequency converter 3.
Master control set 5 can adopt central process unit of the prior art, and central process unit sends frequency variation signals to frequency converter 3, with the startup frequency of control motor, thereby can alleviate the rush of current that electric motor starting moment is subject to.Compared with prior art, utilize frequency converter to replace fluid coupling of the prior art, improved the convenience of design and installation.
The control input end of above-mentioned frequency converter 3 can link to each other by the control output end of bus with master control set 5, and described control input end and control output end define according to the hardware setting of concrete chip and frequency converter.For example, carry out communication by the CAN bus.Signalling methods can adopt electric current loop to communicate, and communication interface adopts 4 line systems to carry out the serial communication of full duplex.Utilize 20mA current delivery data, current signal is difficult for being interfered when transmitting on the line, and reliability is high, and communication quality can well be guaranteed.Many the modes that continuous transport plane 1 adopts the data section division point to upload are aggregated into master control set 5 at last.
On the basis of above-described embodiment, this control system comprises that also this information collecting device 6 is arranged on transport plane 1 or the elevating conveyor 2, and links to each other with master control set 5 for the information collecting device 6 that gathers transport plane 1 or elevating conveyor 2 device parameters.Information collecting device 6 is specifically as follows temperature sensor or pressure sensor, to gather the information such as change speed gear box bearing temperature, lubricating oil temperature, oil level and oil pressure in the variable-frequency motor.Analog data is not suitable for long Distance Transmission, and long Distance Transmission analog signals can be subject to serious interference, can not get actual value.Therefore, the present embodiment is arranged on information collecting device 6 on transport plane 1 or the elevating conveyor 2, can carry out data acquisition nearby, transmits by the CAN bus.In order to reach better control ability, use the more high-rise host-host protocol CANopen of CAN bus, to obtain more information.
The below specifically describes the working process of control system: after at first system powers on, information collecting device 6 will gather the information such as change speed gear box bearing temperature, lubricating oil temperature, oil level and oil pressure in the variable-frequency motor, master control set 5 compares the information that collects and the standard value that sets in advance, if comparative result does not meet the requirement of setting, then report to the police; If comparative result meets the requirement of setting, 5 of master control sets further detect frequency converter 3 states by the electric current loop communication modes, if frequency converter 3 state mals then report to the police, frequency converter 3 states are normally then controlled the frequency starter motor of frequency converter 3 to set.
The mining scraper transport control system that the utility model embodiment provides is by arranging variable-frequency motor and master control set, utilizes the startup frequency of master control set control variable-frequency motor, thereby can alleviate the rush of current that electric motor starting moment is subject to.Compared with prior art, improved the convenience of design and installation.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of various embodiments of the present invention technical scheme.
