Detailed Description
To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Generally, the following three problems mainly exist in the information acquisition and monitoring of ship equipment:
(1) the real-time acquisition and monitoring of the ship equipment information are difficult. Except that a few large-scale ship companies collect and monitor the real-time information of the ships, the onshore management personnel cannot timely master the actual navigation conditions of the ships due to high cost of collecting and monitoring the ships along the river in small-scale ship companies and most of offshore ships, and the ship information collection lacks timeliness.
Specifically, the existing device has a single interface and insufficient compatibility. Because the types of turbine equipment are different and the data interfaces are different, the acquisition monitoring equipment needs to be configured according to the interface type and the data type aiming at the difference, and therefore, the data acquisition is carried out by using various different acquisition monitoring equipment; for example, some devices are digital quantity interfaces, some devices are analog quantity interfaces, some devices are communication interfaces, and the data acquisition and monitoring devices need to read data and need to be matched with the interfaces, but the existing device has a single interface, and needs to be configured with a plurality of acquisition and monitoring devices to meet the requirement of data acquisition of turbine equipment.
(2) The data acquisition technology is relatively backward and the working efficiency is low. Taking oil consumption data acquisition of small and medium-sized ship companies as an example, the oil consumption data acquisition is mostly read and registered at a specific time point through cabin workers, summarized into a table in a specified time range, fed back to the companies in an email mode, and generalized and researched by the companies in a unified way. The acquisition mode has poor real-time performance and consumes a large amount of manpower and material resources.
Specifically, data conversion and analysis can be performed only on a specific protocol, and the conversion capability of data of multiple protocol types is not available. At present, many turbine equipment outputs operation data through a communication interface, acquisition equipment reads the data and needs to perform protocol conversion and data analysis, the data output by different turbine equipment follows different protocols, and all the equipment needing to be acquired and processed have the conversion and analysis processing capacity of multi-protocol data.
(3) The three-in-one technology for real-time data acquisition, processing and transmission of ship equipment is still not perfect and has insufficient compatibility. The existing acquisition equipment can only acquire data aiming at certain equipment or certain specific interface equipment; data conversion can be carried out only aiming at a specific protocol; the acquisition device does not have a transmission function and needs to be realized through other devices. The compatibility, convenience and automation level of the acquisition equipment still need to be improved.
Specifically, the data transmission device is not integrated with the acquisition processing device, and needs to be configured separately (generally, an additional data transmission device is configured, and the acquired data is transmitted to the transmission device first).
In an optional implementation manner, the utility model discloses a scheme provides a collection monitoring box of boats and ships turbine equipment running state, mainly used boats and ships turbine equipment's state collection, processing, monitoring and data transmission. Specifically, the data of the ship turbine equipment can be collected and processed, the centralized monitoring and alarming of the running state of the ship turbine equipment are realized, a ship-shore communication link is established, and the collected running and alarming state information of the ship turbine equipment is remotely transmitted to a ship management platform on the shore in real time, so that a manager on the shore can monitor and remotely manage the ship in real time; the problem that the acquisition interface is single and cannot be compatible with various devices can be solved; the problem that the protocol conversion function is single and various types of data cannot be processed can be solved; moreover, the remote data transmission function is integrated, and other equipment does not need to be configured.
According to the utility model discloses an embodiment provides a monitoring devices for boats and ships. Referring to fig. 1 to 4, a schematic structural diagram of an embodiment of the device of the present invention is shown. The monitoring device for a ship may include: the device comprises a box body, and an acquisition module, a protocol conversion module, a data processing module and a data transmission module which are arranged in the box body.

Specifically, the data processing module may be configured to perform data processing on target information obtained through format conversion to obtain target information with an actual physical meaning, determine whether the target information exceeds a set threshold, and initiate a warning message when the target information exceeds the set threshold.
For example: data processing, on one hand, the acquired numerical values can be converted into data with actual physical significance, for example, the output signal range of a sensor for measuring the shaft temperature is 4-20 mA, corresponds to 0-100 ℃, 10mA is actually output in the measuring process, no physical significance exists, data processing is needed, and the data are (10-4)/(20-4) × 100 ℃ ═ 37.5 ℃, and finally, the data with actual significance are obtained; another aspect may be to perform alarm processing based on the data ultimately obtained that is of practical significance.
Optionally, the data processing module may include a siemens P L C-1200 series module.
