Description

Real-time vibration environment data acquisition device

Technical Field

The utility model relates to the field of environmental data acquisition, in particular to real-time vibration environmental data acquisition equipment.

Background

With the continuous improvement of navigation technology, sea transportation becomes an important transportation mode in the transportation process of large equipment. Compared with land transportation, the sea transportation is more convenient and has less influence on the environment along the way. But the equipment is more complex to influence by the environment in the transportation process using large vessels than in land transportation. In severe weather conditions, the hull can produce significant sloshing and vibration, especially when hurricanes and billows are encountered, the hull bumps very much. This results in the electronic equipment provided on the ship and the heavy equipment transported to it being subject to sloshing and vibration along with the hull. Such vibrations may cause damage to the equipment being carried. Therefore, during transportation, real-time monitoring of vibration parameters in the equipment transportation environment is required. By monitoring the real-time vibration parameters, the ship equipment can be timely reinforced, and the collected environmental signals can be used for subsequent assessment of equipment states and prediction of service lives. However, the current acquisition device is difficult to acquire and process the vibration environment data in real time.
