Abstract
The utility model discloses a programmable logic controller (PLC) long-distance wireless monitoring system of a ship unloader. The PLC long-distance wireless monitoring system of the ship unloader comprises at least one PLC, an industrial personal computer which is connected with the PLC in one-to-one correspondence, and a server. The industrial personal computer is connected with a wireless network sending device. The server is connected with a wireless network receiving device. Data of the PLC is sent out by the wireless network sending device to the wireless network receiving device. By means that the wireless network sending device is disposed at a terminal of the PLC of the ship unloader, and the wireless network receiving device is disposed at a control centre, the PLC long-distance wireless monitoring system of the ship unloader achieves long-distance management of operating information of the ship unloader, especially achieves the long-distance management of a port with a plurality of ship unloader PLC terminals, improves management efficiency, and avoids human resources waste caused by manual operation.
Description
Technical field
The utility model relates to a kind of long distance control system, specifically, relates to a kind of ship unloaders PLC remote wireless monitoring system.
Background technology
Electrified and intelligent along with the harbour, ship unloaders generally all have independently PLC control system at present, are used to write down and control the job information of ship unloaders; Yet; Generally have certain distance between the ship unloaders, and also have certain distance between ship unloaders and the control center, and can not communicate by letter each other; Control center can not in time obtain the job information and the failure message of ship unloaders, is not easy to unified monitoring and fault is in time handled.
Based on this, how to invent a kind of wireless supervisory control system, use Radio Transmission Technology to pass to control center the PLC job information, can grasp and monitor ship unloaders running condition.
Summary of the invention
The utility model can't unified monitoring and the problem of management in order to solve existing ship unloaders PLC control system, and a kind of ship unloaders PLC remote wireless monitoring system is provided, and achieves a butt joint into monitoring of the ship unloaders PLC in the wireless network and management, conveniently, practical.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to be achieved:
A kind of ship unloaders PLC remote wireless monitoring system; Comprise at least one PLC; And with the industrial computer that this PLC connects one to one, also comprise server, said industrial computer is connected with the wireless network sending set; Said server is connected with radio receiver, and plc data is sent to radio receiver by the wireless network sending set.
Further, described wireless network sending set comprises network interface card, with this network interface card bonded assembly first conv, and with the first conv bonded assembly transmitting antenna, said network interface card connects industrial computer.
Further again, described radio receiver comprises receiving wire, with said receiving wire bonded assembly second conv, and the said second conv Connection Service device.
In order to prevent thunderbolt, described transmitting antenna and/or receiving wire are provided with lightning protection device.
Preferably, described lightning protection device is a discharging rod.
Compared with prior art; The advantage and the good effect of the utility model are: through at ship unloaders PLC end the wireless network sending set being set; And the wireless network receiving device is set in control center, realized telemanagement, particularly for harbour with many ship unloaders PLC terminals to the ship unloaders job information; Improved the efficiency of management, the waste of human resource of having avoided manual operation to cause.
After the detailed description in conjunction with advantages the utility model embodiment, other characteristics of the utility model and advantage will become clearer.
Description of drawings
Fig. 1 is a kind of embodiment block diagram of ship unloaders PLC remote wireless monitoring system that the utility model proposes.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done explanation in further detail.
Embodiment one, referring to shown in Figure 1, and the ship unloaders PLC remote wireless monitoring system of present embodiment; Comprise the PLC that is arranged on the ship unloaders,, then include many PLC accordingly if need many ship unloaders of remote monitor and control; Every PLC industrial computer that connected one to one is used for gathering, storing connected plc data, is provided with server in control center; For ease the server unified monitoring, manage the work data of all ship unloaders PLC; Said industrial computer is connected with the wireless network sending set, and said server is connected with radio receiver, and each industrial computer is sent to radio receiver with connected plc data through the wireless network sending set; And then be sent to server, by the server unified monitoring, manage each plc data.
As a concrete embodiment; Described in the present embodiment wireless network sending set comprises network interface card, with this network interface card bonded assembly first conv, and with the first conv bonded assembly transmitting antenna; Said network interface card connects industrial computer; Industrial computer through network interface card, after the first conv conversion process, is sent plc data by transmitting antenna.Industrial computer at every ship unloaders is installed remote control software REALVNCV.Utilize software to distribute an independent IP address for every ship unloaders,, and can carry out remote monitoring and administration to ship unloaders PLC then according to monitoring Control Software distribution role-security so that server communicates by letter with every ship unloaders.
Accordingly, described radio receiver comprises receiving wire, with said receiving wire bonded assembly second conv, and the said second conv Connection Service device.Receiving wire receives the signal that transmitting antenna sends over, and it is transferred to second conv, carries out being sent to server after the conversion process, is analyzed, monitors and managed by server.For the radiowave that prevents to send is absorbed by the ore in sand form in stockyard, avoid packet loss in the plc data transmission way, preferably receiving wire is installed on the high tower of High-Pole Lamp 35 meters of height apart from ground.The plc data that receives is passed to server through the conv that is installed in control center.
In order to prevent thunderbolt, described transmitting antenna preferably is provided with lightning protection device, as a same reason, described receiving wire also preferably is provided with lightning protection device.Described lightning protection device can adopt discharging rod to realize.Can effectively ensure the safety of equipment.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
