Abstract
Disclosed is a water inflow alarm device for a cargo hold of a ship. The water inflow alarm device for the cargo hold of the ship comprises water level detectors arranged in a cabin, and a PLC monitor, wherein the water level detectors are connected with intelligent junction boxes, two RS485 interfaces are arranged on the PLC monitor, one of the RS485 interfaces is connected with a touch screen, and the other RS485 interface is used for being connected with a bus which is composed of the intelligent junction boxes and a repeater in a connected mode. The water inflow alarm device for the cargo hold of the ship has the advantages of being simple in wire distribution, good in expansibility, high in reliability, attractive and simple in appearance, easy to operate, simple in installation and debugging, flexible in alarm display, convenient to modify and good in expansibility.
Description
Technical field
The utility model relates to a kind of cargo hold water inlet warning device.
Background technology
At present, the weak point that cargo hold water inlet warning device exists is, and is interconnected owing to not using bus mode processed to carry out, and each water level detector and repeater all are connected to watch-dog by cable one by one, and the complicated wiring cost of wiring is high; What water level monitoring adopted is the detector of switching value, and each cargo hold need use two water level detectors, and system monitoring is less than concrete height of water level.Alarm indication is water inlet warning and the pre-alarm information of utilizing the every cabin of square LED light indication, and the pilot lamp of the more uses of cargo hold is also just more, and reliability is lower, and system extension is relatively poor.
The utility model content
Its purpose of the utility model just is to provide a kind of cargo hold water inlet warning device, have the advantages that wiring is simple, extendability is better, reliability is higher, and good looking appearance is succinct, easy to operate, Installation and Debugging are simple, alarm indication is flexible, modification is convenient, extendability is strong.With bussing technique and liquid crystal control techniques, can report to the police to the cargo hold damage and water inflow accurately in real time.
The technical scheme that realizes above-mentioned purpose and take, comprise the water level detector that is located at the cabin, water level detector connects Intelligent wiring box, and PLC watch-dog, described PLC watch-dog is provided with two RS485 interfaces, one of them connects touch-screen, and the bus that another is used for Intelligent wiring box is connected with repeater is connected.
Compared with prior art the utlity model has following advantage.
Due to the control structure design of having adopted four-wire system bussing technique and liquid crystal control techniques, thereby have the advantages that wiring is simple, extendability is better, reliability is higher, and good looking appearance is succinct, easy to operate, Installation and Debugging are simple, alarm indication is flexible, modification is convenient, extendability is strong.With bussing technique and liquid crystal control techniques, can report to the police to the cargo hold damage and water inflow accurately in real time.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure principle schematic block diagram.
Embodiment
This device comprises the water level detector that is located at the cabin, water level detector connects Intelligent wiring box, and PLC watch-dog, as shown in drawings, described PLC watch-dog is provided with two RS485 interfaces, one of them connects touch-screen, and the bus that another is used for Intelligent wiring box is connected with repeater is connected.
Described PLC watch-dog is the PLC module of Siemens S7-200 series; Described touch-screen is Siemens Smart700 touch-screen.
Described Intelligent wiring box is provided with safe isolated gate.
Described PLC watch-dog is provided with alternating current 220V primary power and direct current 24V auxiliary power.
This assembly monitor device adopts the PLC module of Siemens S7-200 series, and this module has two RS485 interfaces, and one of them is used for and Siemens Smart700 touch panel communication, and another is used for being connected bus with Intelligent wiring box with repeater and is connected.
Toggle switch on the functional circuit plate of Intelligent wiring box inside makes it have the addressing function, and possesses the input interface of two kinds of water level detectors of analog quantity and switching value.
Embodiment
As shown in Figure 1, this device can be by primary power (alternating current 220V) or auxiliary power (direct current 24V) powered operation, in case the primary power dead electricity, automatically switch to by auxiliary power and power, send simultaneously power fail sound, visual alarm, after primary power recovers, automatically be transformed into the primary power power supply.
watch-dog is the brain of whole device, it is in charge of the Intelligent wiring box that configures in device, the equipment such as repeater and touch-screen, to the continual monitoring that circulates of the signal of the water level detector that is linked into Intelligent wiring box, analyze judgement according to the logical relation of setting, the signal that in time output is correlated with according to the result of analyzing is to linkage, in a single day export immediately sound and light alarm when reporting to the police when finding that in certain cargo hold, water level reaches, and alerting signal is sent to repeater, touch-screen and VDR system, and the position, cabin and the time of fire alarming that occur to report to the police are preserved for historical query in touch-screen.The water inlet water level value in this cabin will be presented in touch-screen in real time simultaneously, and the position that operation touch-screen " the historical warning " key can be reported to the police the cargo hold generation and time showing are out.
Embodiment of the present utility model illustrates, and various variations or the remodeling made by those of ordinary skills can not break away from scope of the present utility model.
