Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Distributed Monitor and Alarm System for Ship Engine Room peculiar to vessel of the present utility model adopts three layers of physical arrangement, and every layer concrete function is as follows:
Bottom: gather substation by some field monitorings and consist of, each field monitoring gathers substation and possesses independently collection and control ability, possesses the communication interface function.Particularly, field monitoring gathers the RS-485 bus standard interface that substation adopts widely used two-way, balance in the Industry Control, can with duplex mode communication, support multiple spot to connect long transmission distance, transfer rate is fast, but multistation is interconnected, realizes Monitoring and Controlling network on a large scale, and equipment carries configuration software, reliability is high, and is with low cost.Although it is very extensive that 485 buses are used, and breaks down easily, the utility model is taked following innovative approach: (a) data line adopts twisted-pair feeder, sets up shielding line as ground wire, and reliable ground connection; (b) 485 signals and power supply are isolated fully, thus the impact of elimination common mode voltage; (c) at the starting end and the terminal resistance that finishes 120 ohm of end devices of 485 communications, make the impedance of cable continuous, avoid the signal reflex in the telecommunication cable, guarantee that communication is reliable; (d) adopt the hub stelliform connection topology configuration; (e) improve the load capacity of 485 buses with 485 converters of charged, high capacity 485 chips, low baud rate wire rod.
Middle layer: be communication layers, gather substation with each field monitoring of bottom and carry out communication by 485 buses that the data that each field monitoring of bottom gathered the substation collection are delivered to the upper strata, and warning message is delivered to the warning processing unit.
Upper strata: be information management, data analysis and policer operation layer, for the monitoring management personnel provide real-time Monitoring Data, and provide data results, can select to carry out automatic or manual control.Its composition comprises the active station that the human interface devices such as main control server and display, printer, touch-screen, keyboard form.
As shown in Figure 2, in first embodiment of the present utility model, comprise administration and supervision authorities, policer operation layer and I/O observing and controlling layer.Wherein administration and supervision authorities, policer operation layer are the upper strata, and I/O observing and controlling layer is the middle layer.I/O observing and controlling layer comprises the I/O bus and hangs over DCS(scattered control system on the bus) controller, the DCS controller is responsible for collection in worksite control.Bottom comprises that several field monitorings gather substation (each ellipse namely represents a field monitoring and gathers substation among Fig. 2), each field monitoring gathers substation and comprises for 4-20mA equipment in the distributed collection cabin, the various I/O fasteners of the on-site signals such as discrete magnitude, all I/O fasteners that each field monitoring gathers in the substation hang on the I/O bus that connects the DCS controller by a field-bus interface card, realize that the data message in the field bus system is mapped to corresponding data message on original I/O bus, such as the fundamental measurement value, alarming value or setting value etc. are so that the information that the fieldbus of seeing at the DCS controller comes is just as from a traditional DCS equipment card.Realized that so just the field bus technique on the I/O bus is integrated.
The advantage of this embodiment scheme is relatively simple for structure, and shortcoming is the restriction that integrated scale is subject to the field-bus interface card, relatively is fit to the boats and ships monitor and alarm system of middle-size and small-size non-unmanned engine room.
As shown in Figure 3, in second embodiment of the present utility model, comprise administration and supervision authorities, policer operation layer, LAN(LAN (Local Area Network)) and the I/O network interface.Wherein administration and supervision authorities, policer operation layer are the upper strata, and LAN and I/O network interface are the middle layer.Bottom comprises that several field monitorings gather substation (each ellipse namely represents a field monitoring and gathers substation among Fig. 3), each field monitoring collection substation comprises the various I/O fasteners for the on-site signals such as 4-20mA equipment, discrete magnitude in the distributed collection cabin, all I/O fasteners that each field monitoring gathers in the substation hang on the LAN by a field-bus interface card, perhaps hang on the LAN by the I/O network interface.Fieldbus Control is carried out the control function of information, measurement and field instrument and all can be browsed and revise at the upper strata active station.
The advantage of this embodiment scheme is some controls and the computing function that must be finished by the DCS controller among the upper embodiment, transfer to cabin field instrument and the equipment of I/O fastener and realize, and parameter or the data message that can obtain being correlated with at active station interface, upper strata.Its another advantage is not need original upper strata active station is changed, and is less on the original system impact.Relatively be fit to the high Monitor and Alarm System for Ship Engine Room of large automatic boats and ships degree, such as the unmanned engine room.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic conception of the present utility model, all should think to be included within the protection domain of the present utility model.
