Problems solved by technology
[0002] At present, in marine systems, sensors are generally powered by ordinary switching power supplies, and each sensor needs to be equipped with a separate switching power supply. When the switching power supply corresponding to a certain sensor fails, the entire switching power supply needs to be replaced. Resulting in higher maintenance costs for marine systems
In addition, the existing switching power supply itself generally does not have an online monitoring function, and the marine system cannot monitor the power supply status of each sensor in real time, resulting in low safety of the marine system

The invention discloses a sensor power supplying device used for a ship. The device includes a single-chip microcomputer, a sensor power-supplying circuit and a power supply circuit. The sensor power supplying circuit includes overvoltage and overcurrent protection modules, DC-DC conversion modules and monitoring modules. Output ends of the overvoltage and overcurrent protection modules are connected with input ends of the DC-DC conversion modules and control ends of the overvoltage and overcurrent protection modules are connected with output ends of the DC-DC conversion modules. The output ends of the DC-DC conversion modules are also connected with input ends of the monitoring modules and sensors. Output ends of the monitoring modules are connected with input ends of the single-chip microcomputer. The DC-DC conversion modules output a first voltage to the overvoltage and overcurrent protection modules and the monitoring modules. The overvoltage and overcurrent protection modules are switched on or switched off according to a first preset voltage value and a first voltage value. The monitoring modules output monitoring electrical signals to the single-chip microcomputer according to a second preset voltage value and the first voltage value. The sensor power supplying device used for the ship reduces the maintenance cost of a ship system and improves the security of the ship system.
