Abstract
The utility model relates to an accessory device of a ship unloader control system, in partiucalr to a belt conveyor signal transmission control device for a ship unloader. The belt conveyor signal transmission control device for the ship unloader comprises wireless communication equipment and an exchanging device (2) and is characterized in that the wireless communication equipment is a corresponding wireless sender (5) and a corresponding wireless receiver (6), the wireless sender is connected to a belt conveyor PLC (4) through a signal transmission wire (3), the wireless receiver is connected with the exchanging device through a signal transmission wire, and the exchanging device is connected with a ship unloader PLC (1). The belt conveyor signal transmission control device has the advantages of being accurate, efficient and low in fault rate, and equipment service life is prolonged.
Description
Technical field
The utility model relates to the accessory device of ship unloaders control system, particularly belongs to the transmitting device of a kind of ship unloaders belt feeder signal.
Background technology
All the time, the vibra feeder of the ship unloading equipment that at home and abroad most of ore terminal uses is all that the tape velocity detector that is arranged on ship unloaders belows by employing detects belt feeder operation conditions and obtains signal, tape velocity detector friction belt is obtained belt feeder run signal, then signal is delivered to ship unloaders PLC control system, controls the operation of ship unloaders vibra feeder mechanism.
Often there is following defect in this kind of operating structure: 1, on-the-spot dust is more, and tape velocity detector always friction belt reduces its life-span, and frequent diversion fee is larger, and has reduced actv. work-hours; 2, when ship unloaders run to belt machine tail part, owing to there is gap between belt feeder adhesive tape and tape velocity detector, cause tape velocity detector to work hardly, control system cannot receive accurate signal, sometimes even causes potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of novel ship unloaders belt feeder signal transmission control unit, receives to reach the object that signal is accurate, reduce equipment failure rate, increase work efficiency.
Belt feeder signal transmission control unit for ship unloaders provided by the utility model, comprise Wireless Telecom Equipment and switch, it is characterized in that, described Wireless Telecom Equipment refers to corresponding radio transmitters and wireless receiver, wherein, radio transmitters is connected to belt feeder PLC by signal transmssion line, and wireless receiver is by signal transmssion line connection exchange device, and switch is connected to ship unloaders PLC.
Belt feeder signal transmission control unit for ship unloaders provided by the utility model, do not using on the basis of tape velocity detector, directly gather the run signal of belt feeder from substation by signal transmssion line, by wireless network, belt feeder run signal is transferred to ship unloaders PLC, ship unloaders PLC carries out, after signal processing, automatically controlling the operation of vibra feeder; There is precise and high efficiency, failure rate is low, extension device and benefit from the good effect in life-span.
Brief description of the drawings
Accompanying drawing part discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model integral structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, belt feeder signal transmission control unit for ship unloaders provided by the utility model, belt feeder PLC 4 is connected to radio transmitters 5 by signal transmssion line 3, and wireless receiver 6 is by signal transmssion line connection exchange device 2, and switch is connected to ship unloaders PLC 1.Belt feeder PLC in substation is connected to radio transmitters by the utility model, signal is transmitted into the wireless receiver on ship unloaders, wireless receiver is transferred to switch 2 by signal transmssion line after receiving signal, switch is connected to ship unloaders PLC, the run signal of belt feeder is transferred to ship unloaders PLC, ship unloaders PLC, after signal is processed, controls the operation of vibra feeder automatically.
In addition, ship unloaders PLC is through dragging optical cable and the Communication ray end equipment of making, signal is transferred to ship unloaders the first operator's compartment PLC active station, and show belt running state in CMS on operator's compartment industrial computer equipment, ship unloaders driver is shown and is carried out real-time judge and control by state.
