Embodiment 1

[0026] An embodiment of the present invention provides a remote power-off device, see figure 1 , the device includes a controller 1, a relay 2, and a power-on delay relay 3.

[0027] Wherein, the controller 1 is used to receive a power-off command from the control device 4, the power terminal of the controller 4 is connected to the power terminal of the electric device 5, and the control device 4 is arranged in the activity area of ​​personnel. The control terminal of the relay 2 is connected to the output terminal of the controller 4 , the movable contact of the relay 2 is connected to the power supply terminal of the electrical equipment 5 , and the normally open contact of the relay 2 is connected to the power supply 6 . The control end of the energization delay relay 3 is connected with the power supply 6 , the movable contact of the energization delay relay 3 is connected with the power supply end of the electrical equipment 5 , and the normally closed contact of the ener...

Embodiment 2

[0048] An embodiment of the present invention provides a remote power-off system, see Figure 4 , the system includes a control device 21 and a remote power-off device 22, the remote power-off device 22 is the remote power-off device described in Embodiment 1, and the control device 21 and the remote power-off device 22 are wired or wirelessly connected.

[0049] Optionally, the control device 21 may be a computer.

[0050] The embodiment of the present invention replaces the control circuit board and the relay in the prior art with the relay, the power-on delay relay, and the controller to complete the power-off of the electrical equipment, and the device does not need to keep the power-on state, which saves electric energy and improves safety. Moreover, controlling the power-off of the electrical equipment through the on-off of the relay does not need to limit the electrical equipment to the electrical equipment driven by direct current as in the prior art, and is more wide...

Abstract

The invention discloses a remote outage device and a system, and belongs to the field of circuit control. The device comprises a controller, a relay and an energization time delay relay, wherein the controller is used for receiving an outage instruction of control equipment; a power supply end of the controller is connected with a power supply end of electric equipment; a control end of the relay is connected with an output end of the controller; one of a movable contact of the relay and a normally open contact of the relay is connected with the power supply end of the electric equipment, and the other one of the movable contact of the relay and the normally open contact of the relay is connected with a power supply; a control end of the energization time delay relay is connected with the power supply; and one of a movable contact of the energization time delay relay and a normally closed contact of the energization time delay relay is connected with the power supply end of the electric equipment, and the other one of the movable contact of the energization time delay relay and the normally closed contact of the energization time delay relay is connected with the power supply. According to the device and the system, an energization state is not required to be kept all the time, so that electric energy is saved; the safety is improved; and an application is wide.

Description

technical field [0001] The invention relates to the field of circuit control, in particular to a remote power-off device and system. Background technique [0002] During the operation of the ship, various emergencies and emergencies may be encountered, such as severe weather. When an emergency or emergency occurs, in order to avoid accidents as much as possible, most of the electrical equipment on board will be powered off to protect the safety of personnel, equipment, and the hull. [0003] Because most of the electrical equipment is generally placed far away from the activity area of ​​people or in places where people are not easy to reach, such as computers used to control the speed of ships, radars used for detection, and radio stations used for communication. If you go to the place where the electrical equipment is placed to power off the electrical equipment one by one, it is not only slow, but also inconvenient. Therefore, a remote power-off device is usually used to...
