Technical field

The utility model relates to a kind of field of intelligent control, particularly a kind of generator intelligence controlling device.

Background technology

Along with the electrification of equipment, generator is just being brought into play very important effect, but at present; manual control model is adopted in the control of generator usually; the adjustment of the start and stop of generating set, voltage, oil pressure, water temperature etc. needs manual operation, and the self-protection function of unit is poor, must special personnel carry out " monitoring " during use; as observe water temperature; situations such as oil pressure are handled at any time in case break down, and so need to drop into a large amount of manpowers; cost is higher, is unfavorable for the development of enterprise.

Summary of the invention

The purpose of this utility model provides a kind of generator intelligence controlling device, and it has realized the Based Intelligent Control of generator, utilizes automation to replace manual operations, thus handled easily can in time pinpoint the problems again, and save human cost.

The utility model comprises voltage transformer, current transformer, multidiameter option switch transducer, operational amplifier, A/D converter, single-chip microcomputer, supply voltage acquisition module and transducer; It is characterized in that: the voltage and current signal that described voltage transformer summation current transformer is gathered the generator three-phase output end respectively is converted into little current signal and sends into the multidiameter option switch transducer, and the signal after the selection is sent into single-chip microcomputer with the signal of described supply voltage acquisition module collection by the A/D converter conversion through the operational amplifier output voltage signal and handled the back and show genset three-phase voltage, electric current and battery voltage by LCD;

Described transducer comprises cooling-water temperature sensor, oil pressure sensor and velocity transducer, gather water temperature, oil pressure, the frequency signal of generating set respectively, described water temperature, fuel injection pressure signal are sent into single-chip microcomputer after being changed by A/D converter, the data of velocity transducer collection are then directly delivered to single-chip microcomputer, after calculating, handle by single-chip microcomputer respectively, be presented on the lcd screen;

The output termination of described single-chip microcomputer outside starting relay, shutdown valve relay and fuel valve relay.

The utility model beneficial effect is: utilize the information of each sensor acquisition to handle by single-chip microcomputer, and the work of control generating set, thus realize utilizing automation to replace manual operations, in the time of handled easily, can in time pinpoint the problems again, and save human cost, have market value preferably.
