Abstract

The utility model relates to a marine multichannel standard data receiver, which consists of a data buffering receiver, a multichannel manager, a clock and timing management module, a controller of an SRAM, the SRAM and an output interface, wherein, the clock and timing management module provides a variety of needed clocks for the system during work. The utility model is characterized in that: an input end of data buffering receiver is connected with a data output end of the device to be monitored through an interface circuit, and the output end is connected with the input end of the multichannel manager; the output end of the multichannel manager is connected with an input end of the output interface through the controller of the SRAM, and the output end of the output interface is connected with an upper system needing to acquire data; the controller of the SRAM is also connected with the SRAM. The utility model provides a unified standard which can be followed during designing the data interface of the device of marine engine system, which not only ensures that the data management system and the upper monitoring system only need one data interface, but also obtains standard IEC 61162 protocol data file.

Description

Multichannel normal data receiver peculiar to vessel

Technical field

The utility model belongs to field of ship engineering, is a kind of multichannel normal data receiver peculiar to vessel specifically.

Background technology

The exchanges data of ship equipment is with shared for convenience, International Electrotechnical Commission (IEC) has worked out the IEC61162 agreement, this agreement and NMEA (National marine electronicsassociation, NMEA 0183 operating such USA).The IEC61162 agreement is the standard of single telephone transmitter, a plurality of telephone receivers, and it has stipulated hardware electrical characteristic, transfer of data, data format protocol and data content.Among the IEC61162, for ship automatic identification system (AIS), global positioning system (GPS), log, echo sounder, wind direction instrument, equipment such as gyro compass have been made clearly regulation.But for host computer system, fuel system, oil system, cooling water system, air inlet system and exhaust system, boiler, equipment such as subsidiary engine, though also there are many state parameters need transmit and record, the not corresponding definition of IEC61162.Even, so far, also have many equipment not have special data output interface.Along with the raising of development of technology and managerial skills and requirement, require to monitor and manage for the operational factor and the state parameter of ship equipment.Because the equipment on the boats and ships is numerous, the data of these equipment outputs all be received, then need management system for monitoring (equipment) to possess a lot of data-interfaces, and the control of Data Receiving and data organize also more complicated.

Summary of the invention

The purpose of this utility model provide a kind of for marine engine room system (according to the shipbuilding regulation and stipulation) must monitoring equipment (and parameter), expand according to the IEC61162 agreement, formed the multichannel normal data receiver peculiar to vessel of the data format of standard, to overcome above-mentioned deficiency.

To achieve these goals, the utility model is by the data buffering receiver, multichannel management device, clock and time control module, static memory (SRAM) controller, static memory and output interface constitute, wherein clock and time control module provide work required all kinds of clocks for system, be characterized in: the input of data buffering receiver links to each other with the data output end of required monitoring equipment by interface circuit, its output and multichannel management device input join, the output of multichannel management device is connected with the input of output interface by the static memory controller, the output of output interface is connected with the upper system that needs image data, also is connected with static memory on the static memory controller.

Above-mentioned data buffering receiver is a plurality of independently serial data buffering receivers arranged side by side, realizes that the independent of multichannel data receives.

Above-mentioned multichannel management device input also is connected with a tunnel.

Above-mentioned static memory is two independently static memories.

The utility model can make the equipment of marine engine room system (the IEC61162 agreement does not have definition), and the unified standard that can follow is arranged when the design data interface.Its function is: can receive the multi-channel serial port data simultaneously; Data are preserved with the form of file, and preserve at that time temporal information; Requirement according to data management system sends data to management system.The utility model not only makes only data interface of needs of data management system and last level monitoring system (device that promptly needs image data), and what obtain is standard IEC 61162 protocol data files.

Description of drawings

Accompanying drawing is the utility model theory diagram.

Embodiment

Further describe the utility model below in conjunction with accompanying drawing.

The utility model adopts programming device such as FPGA (field programmable gate array), CPLD (complex logic circuit), and programming realizes the multi-channel serial Data Receiving on sheet.Normal data, preservation data and real-time time information with synchronous acquisition IEC61162 form are according to the function (as shown in drawings) of the host computer instruction transmission data of preserving.

Operation principle of the present utility model is: the data buffering receiver front end is also shown a plurality of independently serial data buffering receivers, realizes that the independent of multichannel data receives.Serial data buffering receiver is by serial byte receiver module, and FIFO (first in first out) module and auxiliary statement detect logical constitution; Reception by a state machine control data byte; Clock and time control module provide work required all kinds of clocks for system.Wherein special-purpose timer (can be by the host computer school time and set timing resolution) produces commutator pulse, and tunnel sends application, the generation time sign according to this pulse to multichannel management device; Multichannel management device forms automatically and meets the data file (or data format) of IEC61162 format standard, and manages the break-make (being that multichannel is managed) of a plurality of serial datas buffering receivers and 1 tunnel and the data link of SRAM controller; Adopt two SRAM, utilize ping-pong operation, realize the reliable reception of data and simplify logical design.

Each channel data of the utility model is kept among the FIFO by the automatic reception of serial data buffering receiver, to form the data that meet the IEC61162 format standard by multichannel management device by the SRAM controller again and be kept among the SRAM, form data file with real-time time information.According to the requirement of upper system, in turn SRAM A data (SRAM B received and preserved new data this moment) and SRAM B data (SRAM A received and preserved new data this moment) are sent to upper system by output interface.

Above-mentioned all functions are to be realized by the software that is arranged in the utility model.

The content that is not described in detail in this specification belongs to this area professional and technical personnel's known prior art.
