Problems solved by technology
[0007] The present invention is oriented to the remote monitoring of equipment clusters such as fleets, fleets, fleets, or production equipment, and realizes that all remote equipment in the cluster, such as real-time and quasi-real-time measurement point data of ships, can be continuously uploaded to the central station centrally, and the problem to be solved The technical problem is to provide a remote online monitoring system that has better real-time performance and can monitor the changes of remote equipment measurement point data in a more timely manner under the condition that the data communication link is not completely reliable; Scalability, more convenient access to more remote devices, and more measurement points; better reliability, to ensure that important data will not be lost when the communication network is unstable

Embodiment Construction
[0035] The present invention takes a ship as an example to illustrate the implementation of the remote monitoring system. The industrial computer can be used as a remote terminal, and as a ship-borne system, one ship is set up to establish an Internet link with the central station through a 3G / 2G mobile network. System composition
[0036] The overall scheme and system composition of the specific implementation are as follows: figure 1 As shown, the ship system as the remote terminal 10 includes three major modules: measuring point coding 101, data packaging 102 and file transmission 103, and develop their own corresponding software. These software can directly communicate with the ship equipment to obtain the measuring point data, or communicate with The OPC software communicates to obtain the measurement point data, or communicates with the cabin monitoring software to obtain the measurement point data. The file transfer 103 module can use the FTP protocol to transfer file...

The invention relates to remote monitoring system and method for equipment groups, such as fleet of ships, fleet of vehicles, fleet of machines or production equipment and the like. In order to solve technical problems, a remote on-line monitoring system with better real-time performance, expandability and reliability is provided with consideration of unreliable data communication links. Remote terminals continually upload real-time and quasi-real-time measuring point data to a central station in files, computer memory and network transmission for measuring point encoding adopt the formats ofintegral numbers, and the decimal location fixing method is adopted, so that not only favorable memory, transmission and analysis performance but also excellent readability are achieved; and the remote terminals or codes in one-to-one correspondence with the remote terminals adopt a similar method and are contained in the data files. The measuring point data files adopt names different from the final files before being uploaded, so that whether the transmission process is completed or not can be identified.
Description
technical field [0001] The present invention relates to a remote monitoring system and method, in particular to a remote online monitoring system and method for equipment clusters such as fleets, fleets, fleets or production equipment. Background technique [0002] A ship is a means of transportation or an operating platform for offshore mobile operations, which are scattered in different geographical regions during operation. Under normal circumstances, the technical status and operating conditions of ship-borne equipment are not timely grasped by the shore-based department. To overcome this problem, ship-shore communication and remote monitoring technologies have been developed over the years. Other means of transportation, such as trains, automobiles and airplanes, as well as some production equipment, such as CNC machine tools and construction machinery, are also facing similar problems. [0003] These transportation tools or clusters of production operation equipment c...
