Rongde’s products are based on engaged in marine pasture industry.
Founded in 1996, Shanghai Rongde Mechanical & Electrical Engineering Equipment Co., Ltd. is a member of China Shipping Industry Joint Venture, Shanghai Hi-tech Enterprise, Shanghai Civilization Unit, Pudong New Area R & D Machine. For more than 20 years, we have focused on R & D, production, engineering and service of ship equipment. The liquid level measurement system, valve remote control system, fire protection system, anti-fouling, anti-corrosion equipment, monitoring and alarm device, permanent magnet magnetic coupler and speed regulating device are introduced by Rongde. With excellent product quality, service and competitive price, they become one of the main qualified suppliers of customers such as China Shipyard, China Shipyard, China Merchants Ship, Cosco Sea Group, Fujian Mawei Shipyard, Yangzijiang Shipyard and Hantong Shipyard. At present, the company’s products are based on the ship industry, actively engaged in the marine pasture industry, in 2018, our company in Mawei Shipyard for Fuding City Construction Investment Company to build SSFF150 single-column semi-submersible deep-sea fishing ground I provided a valve remote control system, liquid level telemetry and a number of equipment, is currently in the shipyard commissioning, this year I also for China’s first self-developed large-scale full-submersible deep-sea fishing equipment ,” Deep Blue 1″ provided a large number of equipment; Such as ship on-line management system, carbon dioxide fire extinguishing system, liquid level measuring device, automatic fishing ground control box, valve remote control box, bait system main control box, microwave remote transmission system antenna bridge, etc., at present ,” deep blue 1″ has been put into use, and soon the first batch of domestic far-reaching sea salmon will go to the common people’s table.
“Deep Blue 1” Full-submersible Deep-sea Fishing Equipment
I. Main control/monitoring equipment for fisheries:
1. draught monitoring system
2. ballast tank level monitoring system
3. valve remote control system
4. engine room fire alarm CO2 release system
5. feed feeding system
Function: According to the feeding process, control the related equipment (generator start and stop, water pump start and stop, feeder switch, feeding light switch, etc.) automatic feeding operation; with timing, fixed speed, quantitative feeding function; with emergency stop protection function
6. automation system
Function: Graphical display of draught, ballast liquid level data, ballast, air-permeable valve status; display smoke temperature sensor status, carbon dioxide system status; control switch to ensure that only one place at the same time has control to ensure operational safety; remote control valve switch; remote control feed feeding system operation;
Integration: draught monitoring, ballast level monitoring, valve remote control, engine room fire alarm carbon dioxide release system, feed feeding system;
Hardware: Automatic control box of fishery control room, automatic computer of breeder ship;
7. Distribution Control System
Functions: for security monitoring, as well as underwater video surveillance;
8. video surveillance system
9. equipment monitoring system
a. water quality monitoring
Function: Factual monitoring of water solubility, conductivity, pH value, salinity, temperature, etc.
A sensor is connected to a serial port server via a RS485; the sensor needs to be calibrated periodically;
b. underwater light supplement control
Function: Manually control the underwater light-up switch, with the underwater camera to view the fish;
Control equipment: IO module, using RS485 and serial port server connection;
Function: monitor the voltage state of UPS battery pack, start generator to charge battery pack according to set value, ensure the power supply of electric equipment in fishing ground is normal;
Monitoring equipment: AI module, using RS485 and serial port server connection;
d. microwave remote network
Functions: network with breeders, video surveillance, equipment monitoring and our automation system data to breeders control room;
II. Structure of the equipment monitoring system
The equipment monitoring system belongs to the common “cabin automation system” and “microwave remote transmission network” in essence.
The DI/AI signal input and acquisition in the equipment, as well as the IO module of the traditional RS485 interface used in the output of the IO signal, convert the RS485 signal into the network signal through the serial port server and transmit it to the monitor computer display on the ship through the microwave remote transmission network.
