The CTQD main engine remote control device is suitable for controlling the main propulsion system of different types of marine medium-speed irreversible main diesel engines equipped with reverse and smooth-off stage devices. There is a complete host alarm system, which can accept the host failure and fault stop signals provided by the security system, and realize the automatic deceleration and automatic shutdown of the host due to failure. It can also be designed and produced according to customer needs.
Pneumatic control system ( JNCZJK-A )
The speed control signal is a gas signal / The disconnection and discharge are controlled by the PLC logic program / The speed rises slowly, the speed decreases quickly, and it can be adjusted / The system loses air, the main engine speed and shafting steering remain unchanged / The alarm contact is extended and output to the engine room combination alarm Lights use / support navigation parameter recording system RS-485 standard communication interface

Electrical control system ( JNCZJK-B )
The central control unit adopts a programmable logic controller (PLC) / start, stop and steering logic control / automatic adjustment of the main engine speed, the speed of each gear can be modified / maximum speed limit / combined speed, idle speed, steering time and other important parameters can be adjusted / When the power is lost or the air is lost, the rotation speed of the main engine and the steering of the shaft system remain unchanged / The alarm contact is extended and output to the engine room combined alarm light for use / Support the RS-485 standard communication interface of the navigation parameter recording system

Full gas control system ( JNCZJK-A-1 )
All logic control functions are realized by air-controlled logic valve parts/ slow acceleration, rapid deceleration, adjustable/ system degassing, main engine speed and shafting steering remain unchanged/ alarm contact extension output for engine room combined alarm lights

Shaft remote host (RZ-1)
Fully mechanical control, no interlock, equipped with a host door lever booster mechanism for speed regulation The steering is completed by the mechanical flexible shaft. The console, the engine room is equipped with a combined alarm light and the status indication of the stern. Only the flexible shaft is used for ships whose length is less than 25 meters. The flexible shaft is a wearing part and needs to be replaced regularly

All-electric control system (JNCZJK-B-1)
Electronic governor interface or equipped with servo motor speed control central control unit adopts programmable logic controller (PLC) to control the start, stop and steering logic to control the speed of the main engine automatically. , steering time and other important parameters can be adjusted to support the navigation parameter recording system RS-485 standard communication interface

Host security, monitoring system
The security and monitoring alarm system uses an independent PLC as the core Directly monitor the key operating data of the diesel engine, and at the same time accept the data from the detection and alarm system Only accept external signals to control diesel engine shutdown and override With disconnection monitoring and self-diagnosis function Realize the control of diesel engine starting, injection aid, cylinder lubrication, bypass, external lubricating oil backup pump and external high temperature water backup pump

Host security, monitoring success stories
The 12000WDT product oil chemical tanker marine diesel engine automation system consists of monitoring and alarm system, security system and propulsion control system. The three and the touch screen use Ethernet high-speed communication to exchange data. The core of the system adopts AB B certified by many classification societies. The company's AC500 series PLC, the human-machine interface adopts the European HMI with DNV certificate to indicate the brand Beijer touch screen, the system has the cabin monitoring and alarm system and VDR interface.
