Problems solved by technology
However, at present, the on-board instruments equipped with marine diesel engines can only be monitored by the staff on board, and do not have the function of remotely uploading status data; on the other hand, the traditional GPS positioning system only has the function of sending ship position information. It does not have the function of sending other information; in addition, the use of 3G and other mobile communications has communication blind spots due to the inability to set up base stations at sea, resulting in the inability to guarantee the effective transmission of marine diesel engine operating parameters

Embodiment Construction
[0018] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0019] see figure 1 , a fleet diesel engine remote state monitoring system based on Beidou satellite communication, characterized in that it includes a Beidou communication system 1, a state discrimination and scheduling system 2, and a data acquisition system 3, wherein the data acquisition system 3 collects the engine oil pressure and rotational speed of the diesel engine , cooling water temperature, cylinder head vibration signal, generator three-phase output voltage and output current, starting battery voltage, current and temperature, and encode these signals, and then send them to the state discrimination and dispatching system 2 through the Beidou communication system 1 , the state discrimination and scheduling system 2 judges the running state of the diesel engine, and dispatches the inbound fleet according to the running sta...

The invention discloses a fleet diesel engine remote state monitoring system and monitoring method based on Beidou satellite communication. The monitoring method comprises the steps that a data acquisition system acquires operation parameters, mainly including water temperature, engine oil pressure, rotation speed and cylinder cover vibration signals of the diesel engines, starting voltage, current and temperature of a storage battery, three-phase output voltage and current of a generator, and the like, of all ship diesel engines in a fleet; the parameters are transmitted to a Beidou communication terminal; the operation parameters of the diesel engines in the fleet are transmitted to an ashore remote monitoring platform through a Beidou 1-generation satellite; the remote monitoring platform analyzes and processes data and judges the operation states of the diesel engines; and finally, the arrival fleet is subjected to optimal dispatching according to the operation states of the diesel engines, and arrival delay caused by failure of the diesel engines is reduced.
Description
technical field [0001] The invention relates to the technical field of multi-channel sensor information fusion, in particular to a fleet diesel engine remote state monitoring system and monitoring method based on Beidou satellite communication. Background technique [0002] As the source of power for ships going out to sea, the performance of diesel engines will directly affect the normal navigation of the ships, especially when the fleet enters the port. Once the diesel engine of a certain ship fails, it will affect the subsequent fleet entering the port, resulting in the passage of waterways. congestion. Therefore, if the shore staff can grasp the operating status of the diesel engines of the fleet entering the port in real time, and dispatch ships according to the status, the delays in entering the port caused by diesel engine failures will be greatly reduced. However, at present, the on-board instruments equipped with marine diesel engines can only be monitored by the s...
