Abstract
The invention discloses a remote monitoring method, in particular to a method for real-time monitoring of a ship unloader by utilizing VPN (Virtual Private Network) technology. The method comprises the steps as follows: the data acquisition is carried out by a PLC (Programmable Logic Controller) control device on the ship unloader at a remote end; next, the data is transmitted to a central processing unit of a control center through the internet via a VPN router; and finally, the central processing unit is utilized to analyze the acquired data and judge if the analysis result is normal. The method has the advantages that the problems of the ship unloader in running can be found and solved in time, the labor cost can be saved effectively, and the operation is convenient. Therefore, the method can be widely applied to the monitoring situations of the remote ship unloader.
Description
Technical field
The present invention relates to a kind of long-range control method, be meant that specifically a kind of VPN technologies of utilizing are in ship unloaders and method that ship unloaders are monitored in real time.
Technical background
In the past, often run into following problem as ship unloaders producer: the equipment operation fault alarm is shut down, and the user urges and sending someone immediately, and the engineer all has important task can't go on a journey at body; Equipment fault, on-site maintenance the electrician make a phone call, since different to the degree of understanding of equipment, and communication effectiveness is undesirable; After equipment fault was shut down, the engineer checked at the scene that it is elementary to pinpoint the problems, and solved, and had but spent several days time back and forth in three minutes; After equipment fault was shut down, the engineer checked at the scene that discovery need be got spare part again, causes the client to increase downtime; Or the like these bring a lot of problems: engineer's business travel cost back and forth, factory engineer's cost, the on-the-spot loss that stops production also have immeasurable potential risk: shut down bring jeopardize device security, personal safety.
VPN (Virtual Private Network is called for short VPN) refers to the technology of on common network, setting up dedicated network.Why it is called virtual net; Mainly be because the connection between any two nodes of whole VPN network does not have the required physical link end to end of traditional private network; But the network platform that framework is provided in common network service provider; Like the logical network on Internet, ATM (asynchronous transfer mode), the Frame Relay (frame relay) etc., user data transmits in logical links.It has contained the expansion of the dedicated network of encapsulation, encryption and the authentication link of striding shared network or public network.VPN has mainly adopted tunneling technique, encryption and decryption technology, key management technology and user and equipment identities authentication techniques.
Be platform that basic internet network for we provide information sharing with the TCP/IP protocol suite today.Have benefited from the open property of interconnections of TCP/IP, increasing communication network and smart machine are linked into Internet.Along with the progress and development of modern industry with science and technology, the networking of industrial control field, distributed characteristics are more and more obvious, and demand grows with each passing day.Industry Control progressively develops into distance control mode from traditional field control, and powerful Internet makes distance no longer become a kind of restriction with the data communication technology that reaches its maturity, and therefore industrial control network has obtained extension.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of method of instant, remote monitoring is provided.
The present invention is achieved through following technical proposals:
The application process of VPN in the ship unloaders remote monitoring is characterized in that, this method comprises:
(1) on the ship unloaders of far-end the PLC control device is installed, gathers the data of ship unloaders in running by the PLC control device;
(2) the PLC control device through ship unloaders is connected with vpn routers, and vpn routers wherein is to have VPN service end function and switch function, can connect the INTERNET network; Give vpn routers with the transfer of data that the PLC control device is gathered;
(3) vpn routers is realized that with the central processing unit of control centre network is connected, and the transfer of data of being gathered is arrived central processing unit through the INTERNET network, and central processing unit is analyzed the data of being gathered;
(4) after central processing unit is analyzed the data that received, show, and whether normal analysis result made court verdict through the terminal monitoring device.
As preferably, the vpn routers that is installed in far-end in the application process of above-mentioned VPN in the ship unloaders remote monitoring is connected through the PLC control device ethernet module of ICP/IP protocol and ship unloaders, and vpn routers wherein is installed in device context.
As preferably, when getting into the terminal monitoring device in the application process of above-mentioned VPN in the ship unloaders remote monitoring, add the cipher protection apparatus that covers into.
Beneficial effect: the present invention can find in time that ship unloaders go wrong in running, and in time is resolved, and can effectively practice thrift human cost, handled easily etc.

Embodiment
Below in conjunction with accompanying drawing, enforcement of the present invention is specified:
Embodiment 1
At first ship unloaders are installed, used at far-end, and the PLC control device is installed on the ship unloaders of far-end, gather the data of ship unloaders in running by the PLC control device; PLC control device through ship unloaders is connected with vpn routers; Vpn routers plugs in; Vpn routers wherein is to have VPN service end function and switch function; Can connect the INTERNET network, with the ethernet port of netting twine connection vpn routers and PLC, router has just been carried out the preparation that receives and send data like this; Give vpn routers with the transfer of data that the PLC control device is gathered; Vpn routers realizes that with the central processing unit of control centre network is connected, and the transfer of data of being gathered is arrived central processing unit that central processing unit is analyzed the data of being gathered through the INTERNET network; Central processing unit shows through the terminal monitoring device after the data that received are analyzed, and whether analysis result is made normal court verdict.
In the present embodiment, the vpn routers that is installed in far-end is connected through the PLC control device ethernet module of ICP/IP protocol and ship unloaders; Do not receive external interference for what protect equipment, need be to getting into personnel's specialization of supervisory control system, need be when getting into the terminal monitoring device, add the cipher protection apparatus that covers into.
When the keeper opens the online fault of looking into of plc programming software; Also can open host computer configuration software Real Time Observation equipment operation situation.
In the present embodiment, for the ship unloaders parameter that sets in service fire alarm, strong wind warning, hopper overload, grab bucket overload etc. are arranged; The setting of these parameters can be confirmed according to situation such as actual use occasion, service conditions, also can find early, solve early the problem that ship unloaders possibly occur, and find out the reason etc. that goes wrong for use producer, manufacturer.
In order to monitor the operation conditions of ship unloaders better; Central processing unit is not only analyzed, is judged the data of being gathered; But also data memory device can be set; Immediately store the data of being gathered, store immediately, be analysis, the relatively more useful preparation of do from now on analyzing the gained result.
