The belt conveyor signal transmission control device comprises wireless communication devices and an exchange device (2) and is characterized in that the wireless communication devices are a wireless transmitter (5) and a wireless receiver (6) which correspond to each other, the wireless transmitter is connected to a belt conveyor PLC (4) through a signal transmission line (3), the wireless receiver is connected with the exchange device through a signal transmission line, and the exchange device is connected to a ship unloader PLC (1). The belt conveyor signal transmission control device and method have the advantages of being accurate, efficient, low in failure rate and service life of the device is prolonged.
Description
Technical field
The present invention relates to accessory device and the method for ship unloaders control system, particularly belong to transmission control unit and the control method of belt feeder signal for a kind of ship unloaders.
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; When 2, 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 object of the present invention is to provide a kind of belt feeder signal transmission control unit and method for novel ship unloaders, to reach, receive 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 present invention, comprise Wireless Telecom Equipment and switch, it is characterized in that, described Wireless Telecom Equipment refers to radio transmitters and the wireless receiver matching, 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.
The method of belt feeder signal transmission control unit for ship unloaders disclosed in this invention, is characterized in that, comprises the following steps:
Step 1: gather the run signal of belt feeder, comprise contactless switch summation current transformer double loop signal, be connected to radio transmitters by signal transmssion line, radio transmitters sends this signal after receiving the run signal of belt feeder;
Step 2: wireless receiver receives after the signal of radio transmitters transmission, is sent to switch by signal transmssion line, and switch transfers to ship unloaders PLC;
Step 3: ship unloaders PLC receives signal, controls vibra feeder, allows feed; When belt feeder run signal does not exist, ship unloaders PLC controls vibra feeder and stops feed.
Belt feeder signal transmission control unit and method for ship unloaders provided by the present invention, do not using on the basis of tape velocity detector, directly by signal transmssion line, from substation, gather the run signal of belt feeder, 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, the extension device good effect in service life.
Accompanying drawing explanation
Accompanying drawing partly discloses specific embodiments of the invention, wherein,
Fig. 1, integral structure schematic diagram of the present invention;
Fig. 2, logic theory block diagram of the present invention.
The specific embodiment
As shown in Figure 1, belt feeder signal transmission control unit and method for ship unloaders provided by the present invention, comprise Wireless Telecom Equipment and switch, described Wireless Telecom Equipment refers to radio transmitters 5 and the wireless receiver 6 matching, belt feeder PLC 4 is connected to radio transmitters 5 by signal transmssion line 3, wireless receiver 6 is by signal transmssion line connection exchange device 2, and switch is connected to ship unloaders PLC 1.
As shown in Figure 2, the present invention controls belt feeder PLC in substation the operation of belt feeder, and be connected to radio transmitters by signal transmssion line, radio transmitters is transmitted into the wireless receiver on ship unloaders by the belt feeder run signal collecting, wireless receiver is transferred to switch 2 by signal transmssion line after receiving signal, switch is connected to ship unloaders PLC, and the run signal of belt feeder is transferred to ship unloaders PLC.
Ship unloaders PLC receives after signal, can compare with predefined numerical value, carry out signal processing analysis, then according to Treatment Analysis result, automatically control the operation of vibra feeder, adjust in real time its oscillation frequency, to realize the automatic adjustment of vibra feeder delivery rate.
In specific embodiment, when belt feeder run signal exists, ship unloaders PLC controls vibra feeder oscillation frequency according to the real-time belt feeder run signal gathering; When belt feeder run signal does not exist, ship unloaders PLC stops vibra feeder vibrating feed according to the real-time signal control receiving.The real-time running condition by vibra feeder of ship unloaders feeds back in belt feeder PLC.
While breaking down in ship unloaders communication apparatus and vibra feeder control, at bridge operation platform, be provided with bypass button, driver can its operation of Bypass Control ship unloaders vibrating feed.Ship unloaders PLC can pass through camel bell optical cable and Communication ray end equipment, signal is transferred to ship unloaders operator's compartment PLC active station, and show belt running state in the CMS on operator's compartment industrial computer equipment.
In addition, ship unloaders PLC is through dragging optical cable and the Communication ray end equipment of making, signal is transferred to the operator's compartment PLC active station of unloading a ship, and show belt running state in the CMS on operator's compartment industrial computer equipment, ship unloaders driver is shown and is carried out real-time judge and control by state.
