Description
Technical field
The utility model relates to Ship automatic technique field, particularly relates to a kind of boats and ships extension alarm device.
Background technology
Along with the development of China's shipping industry technology, watercraft engine room monitoring and warning system technology rapidly promote.Extend alarm system is the important component part of monitor and alarm system, is to realize shipboard automation and intelligentized critical system.Boats and ships are a special applied environment, very high to the performance requirement of system.The technology that is applied at present extend alarm system field is mainly the loop configuration forming around RS485.Along with improving constantly of technology, fieldbus and ethernet technology are also more and more extensive in the application of ship domain, and all kinds of extension alarm devices also emerge in an endless stream, but existing extension alarm device versatility is poor, and some is incorporated in Monitor and Alarm System for Ship Engine Room; Some has integrated engineer's called host function, is not suitable for all boats and ships; Some alerting signal input mode, bus mode are single.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of boats and ships extension alarm device.
Of the present utility model, comprise that n extension alarm device is from unit, communication unit, extension alarm device master unit, switching input module and host computer, a described n extension alarm device connects communication module from unit difference electric signal, communication unit electric signal connects extension alarm device master unit, extension alarm device master unit electric signal connecting valve amount load module, switching input module electric signal connects host computer, described extension alarm device master unit comprises storage unit, clock unit, microcontroller, rotary switch, keyboard, toggle switch, buzzer interface, LCD display unit, pilot lamp and hummer, described microcontroller connects respectively storage unit, clock unit, rotary switch, keyboard, toggle switch, buzzer interface, LCD display unit, pilot lamp and hummer.
Described communication unit adopts RS485, CAN bus, three kinds of communication modes of Ethernet, selects communication mode by toggle switch.
Described microcontroller adopts C8051F430 single-chip microcomputer.
Compared with prior art the beneficial effects of the utility model are:
The utility model is stable, reliability is high, false alarm rate is low, it is simple, with low cost to use, not only transmit timely and effectively warning message, also integrate the functions such as engineer is on duty, can improve the reliability that boats and ships are reported to the police, there is very high using value.
Brief description of the drawings
Fig. 1 is one-piece construction figure of the present utility model;

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, comprise that n extension alarm device is from unit 1, communication unit 2, extension alarm device master unit 3, switching input module 4 and host computer 5, a described n extension alarm device connects communication module 2 from unit 1 difference electric signal, communication unit 2 electric signal connect extension alarm device master unit 3, extension alarm device master unit 3 electric signal connecting valve amount load modules 4, switching input module 4 electric signal connect host computer 5, and described extension alarm device master unit 3 comprises storage unit 6, clock unit 7, microcontroller 12, rotary switch 8, keyboard 9, toggle switch 10, buzzer interface 11, LCD display unit 13, pilot lamp 14 and hummer 15, described microcontroller 12 connects respectively storage unit 6, clock unit 7, rotary switch 8, keyboard 9, toggle switch 10, buzzer interface 11, LCD display unit 13, pilot lamp 14 and hummer 15, described communication unit adopts RS485, CAN bus, three kinds of communication modes of Ethernet, select communication mode by toggle switch, and described microcontroller adopts C8051F430 single-chip microcomputer.
The warning message obtaining is sent to extension alarm device master unit by host computer, and master unit is delivered to each terminal according to arranging of self timely and effectively by warning message.On extension alarm device master unit, can carry out the setting of setting on duty and warning message input mode by rotary switch or man-machine interaction, can carry out the local alarm operations such as noise reduction, confirmation by button, and will report to the police in time and configuration information on duty formation packet, send on whole network.Each extension alarm device is arranged on chief engineer room, second engineman, third engineman, electrician and dining room conventionally from unit, drive the public domains such as platform.While generation when reporting to the police, the current on duty sound and light alarm signal that sends from unit of master unit and system setting.If after alerting signal is sent, in setting-up time relevant operator on duty not or fail alerting signal to reply noise reduction processing, system will be automatically in each alerting signal of sending from unit, carries out global call.From unit, can transfer on duty be set at extension alarm device by rotary switch or man-machine interaction, carry out noise reduction and confirm operation by button.After occurring when reporting to the police, system will record the relevant information of this warning, and operator on duty can carry out the operation such as amendment or interpolation of query-related information, calendar clock setting, warning numbering and title in each terminal by man-machine interaction.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
