The ship’s engine telegraph SMT-11 is an autonomous means of communication between the wheelhouse and the engine room, designed to transmit running commands from the wheelhouse to the engine room.
SMT-11 can be installed both as the main means of communication between the wheelhouse and the engine room, and as a backup.
The structure of the telegraph includes command and executive devices.
The command instrument (MTK) is designed to transmit up to 11 commands from the wheelhouse to the engine room.
The executive device (MIT) receives and confirms the execution of running commands in the engine room.
Overview of the SMT-11 system
General description
SMT-MTI The ship’s engine telegraph SMT-11 is an autonomous means of communication between the wheelhouse and the engine room, designed to transmit running commands from the wheelhouse to the engine room. SMT-11 can be installed both as the main means of communication between the wheelhouse and the engine room, and as a backup.
The structure of the telegraph includes command and executive devices.
The command instrument (MTK) is designed to transmit up to 11 commands from the wheelhouse to the engine room.
The executive device (MIT) receives and confirms the execution of running commands in the engine room.
Panel design
The design of the panels of the command and executive instruments was developed taking into account all the requirements for shipboard instruments from an ergonomic and aesthetic point of view.
The command device is equipped with special connectors for connecting large cables. Connectors are fastened with screws to the body of the device, which excludes the possibility of their disconnection in case of strong vibrations.
The panels are made using the latest technologies, from modern materials and have a front surface protection level of IP66.
The operator can change the brightness of the buttons and indicators in accordance with the operating conditions both from the local dimmer and from the central dimming device via a special CAN-DIM bus.
Interaction with the flight data recorder (VDR/S-VDR)
SMT-11 is equipped with an interface for interaction with the voyage data recorder (VDR), which allows you to automatically save information about the commands for each engine transmitted by the navigator from the bridge to the engine room from each control station. Dimming devices via a special CAN-DIM bus.
Watch control in the engine room
SMT-11 is equipped with a built-in watch control function in the engine room, which allows you to control the capacity of the personnel of the Ministry of Defense.
To do this, from the command device installed in the wheelhouse, the navigator sets a special command, which is displayed using light and sound indication on the actuator.
Engine room personnel are considered capable when the given command is confirmed.
Misdirection Command Signaling
The system is equipped with the function of additional notification of the navigator about incorrect execution of the command given from the bridge. After the command is confirmed in the engine room, a timer is activated, after which the system compares the signal of the direction of operation of the engine and the signal received from the actuator. If they differ, an alarm is triggered on the bridge.
Control post architecture
The machine telegraph is made in two versions: for single-shaft and two-shaft power plants.
In total, up to 9 command and 5 executive devices can be involved. It confirms the execution of running commands in the engine room.
Type approvals
SMT-11 is approved by the Russian Maritime Register of Shipping and the Russian River Register.
