The technical problem that solves: in order to solve aforesaid problems of the prior art, the purpose of this utility model is to provide a kind of and realizes automatic operation, autostop, protection automatically, start function for three times, keep accurate starting state automatically, can carry out the main generator group control cabinet peculiar to vessel of manual two kinds of operator schemes.
Technical scheme: in order to reach above-mentioned utility model purpose, the technical scheme that the utility model adopted is:
A kind of main generator group control cabinet peculiar to vessel of the present utility model; it is characterized in that comprising: alarm output device and operational amplifier and cable circuits such as microcomputer control unit, power-supply system, starting output equipment, sensor groups, transmitter group, passive warning input unit, electron speed regulator, stop botton, long-range stop botton, push-button switch harmony, light warning; above-mentioned each parts electrically connect by cable circuit and microcomputer control unit, and by microcomputer control unit its signal are controlled.
Above-mentioned main generator group control cabinet peculiar to vessel, it is characterized in that described sensor groups comprises: speed probe, water temperature sensor, exhaust gas temperature sensor and lubricating oil temperature sensor, above-mentioned transducer is connected with microcomputer control unit by the armoured cable of double layer screen.
Above-mentioned main generator group control cabinet peculiar to vessel, it is characterized in that described transmitter group comprises: lubrication pressure power transmitter, pressurizing and lubricating oil pressure transmitter and charge-air pressure transmitter, above-mentioned transmitter is connected with microcomputer control unit by the armoured cable of double layer screen.
Beneficial effect: as mentioned above, the utlity model has and to realize automatic operation, autostop, protection automatically, start function for three times, keep accurate starting state automatically, can carry out manual two kinds of operator schemes.
Description of drawings
Fig. 1 is the block diagram of main generator group control cabinet peculiar to vessel of the present utility model;
Fig. 2 moves block diagram automatically for the main engine power generation unit of the utility model control.
Embodiment
As shown in Figure 1, main generator group control cabinet peculiar to vessel of the present utility model comprises distribution panelboard, microcomputer control unit and by control units such as the power-supply system of its control, starting output equipment, sensor groups (speed probe, water temperature sensor, exhaust gas temperature sensor) (K calibration), transmitter group (lubricating oil temperature sensor, lubrication pressure power transmitter, pressurizing and lubricating oil pressure transmitter, charge-air pressure transmitter), passive warning input, electron speed regulator, stop botton, long-range stop botton, push-button switches; RS485 communication interface, switching value are reported to the police and are exported warning output unit and operational amplifier and the cable circuit that harmony, light warning etc. constitute.
Each above-mentioned parts electrically connect by cable circuit and microcomputer control unit, and each transducer is connected with microcomputer control unit with the armoured cable of transmitter by double layer screen, and by microcomputer control unit its signal is controlled.The signal of sensor groups output can be frequency signal, resistance signal, voltage signal, current signal, and the armouring of the logical double layer screen of these signals is crossed cable is sent to microcomputer control unit through operational amplifier.Sensor groups has functions such as automatic detection intelligent decision, software automatic zero adjustment, break alarm, line fault warning.
As shown in Figure 2, under the normal electrical electric power thus supplied, main power network signal switch closure makes emergency load and the emergency lighting circuit a part of operate as normal as regular link, when dead electricity, signal carries out data processing through microcomputer control unit, control cabinet sends three " starting " signals of diesel engine, sends action command by main distribution board, and control cabinet control unit starts automatically.If diesel engine starting success, automatically raising speed to rated speed, send the permission switching signal, power to the load, and cut off the trigger circuit of diesel engine automatically.After the diesel engine starting success, diesel engine with automatic raising speed to rated speed, control cabinet is constantly monitored every operational factor of diesel engine, comprise rotating speed, oil temperature, lubricating oil pressure, cooling water temperature, cooling water pressure, exhaust temperature, when unit enters normal condition, control cabinet sends raising speed and signal to reduce the speed according to speed feedback, makes unit keep rated speed.
Stop sign when receiving main distribution board sends sub-gate signal, delays time after 5 seconds, and reduction of speed moves automatic stopping after 3 minutes to idling automatically, is in car state fully, autostop.
During unit operation; if certain parameter; as: rotating speed; oil temperature; lubricating oil pressure; cooling water temperature; the warning system supply voltage; exhaust temperature is out-of-limit; oil pressure occurring crosses low less than setting pressure; coolant water temperature is too high greater than design temperature; the electric voltage exception fault; emergency shutdown then; send the sound and light alarm signal simultaneously; if water temperature is tall and big in design temperature; the warm high fault of oil; then control cabinet will send the sound and light alarm signal; the pairing digital displaying window flicker of this out-of-limit parameter simultaneously; indication is that this parameter is out-of-limit; remind the attendant to intervene, by behind " noise reduction " button, acoustic alarm disappears; visual alarm transfers zero diopter indication to, remain to after this parameter is manually fixed a breakdown always reach normal till.Has the parameter of stop-working protection function for some; rotating speed, lubricating oil pressure, cooling water temperature; when some parameters such as rotating speed, lubricating oil pressure reached the parking setting value, control flow sent stopping in emergency of signal controlling diesel engine automatically, sent the sound and light alarm signal simultaneously.At this moment acoustic alarm signal can be eliminated by " noise reduction " button.But visual alarm has memory effect, and it will remain to the operator on duty always and fix a breakdown, and presses behind the Reset button just to disappear.
If starting failure in the diesel engine 8 seconds then starts after time-delay in 10 seconds once more,, then start for the third time after the time-delay if start unsuccessfully for the second time.As long as once successful, just down move in starting for three times by the program that sets in advance; If continuous three startups are all unsuccessful, then be considered as starting failure, send the sound and light alarm signal.Signal carries out data processing through microcomputer control unit, also can control another startup of unit simultaneously.
The utility model is not to be defined in aforesaid execution mode, in the category that does not exceed the utility model basic fundamental thought, the operator of relevant industries can carry out various deformation to it, and the above-mentioned distortion of carrying out should belong to claim scope of the present utility model.
