Description

Power supply equipment for field operation vehicle

A kind of electric power supply on vehicle for field work, it can be used for doing interim power supply for field work (as scientific investigation, may visit, military operation etc.) and various accident (as emergency dealing, fire fighting and open-air medical aid etc.).

In scientific investigation, geology may be visited, and military operation and some unexpected incidents such as emergency dealing, fire fighting and open-air medical aid etc. all need to use electric energy to start view device equipment temporarily.Because these places do not have electrical network or are difficult to find suitable power network wiring temporarily.Two kinds of methods of many now employings, a kind of is that instrument and equipment carries powered battery, but this mode has strengthened the weight of instrument and equipment, and the battery charge capacity is limited, and energy density is not high, and is impracticable especially for some big power consumption equipment.Another kind method is to use engine to add generating set and powers.For the ease of motor-driven, generally all engine added generating set and be put on the automobile or make special-purpose vehicle (or trailer).Though this method can provide more powerful power supply, in order to obtain the constant frequency and constant voltage alternating current, need to use special engine (vapour is by machine or diesel engine) to drive generator, structure is bigger, takies effective mounting space of various field work vehicles.

The purpose of this utility model is a kind of electric power supply on vehicle for field work of invention, and its available various Operation Vans repacking has more powerful electric energy output, is adapted to field work.

Structure of the present utility model as shown in Figure 1, it has generator 1, distribution board 2, it is characterized in that: the power shaft of generator 1 links to each other with the transfer output shaft of field operation vehicle, the output of generator 1 is connected to dry-type rectifier spare 3, numerical controlled voltage and convertor assembly 4 are arranged, its input links to each other with dry-type rectifier spare 3, output links to each other with distribution board 2, output at dry-type rectifier spare 3 is connected to voltage sensor 6 and current sensor 7, Operation Van's engine numerical control throttle control 8 is arranged, numerical control throttle control 8 links to each other with the throttle control line of Operation Van's engine, standard industrial control 9 is arranged, standard industrial control 9 by the standard serial communication interface with can link to each other with the shared central control computer 10 of miscellaneous equipment, in standard industrial control 9, be inserted with the measurement adaptation module 11 and 12 that links to each other with current sensor 7 with voltage sensor 6, and be inserted with and numerical controlled voltage and convertor assembly 4, numerical control throttle control 8 links to each other with contactor on the distribution board 2 and to its control adapter module of controlling 13,14 and 15, generator 1 is rare synchronous machine.

Accompanying drawing 1 is a structural representation of the present utility model.

General Operation Van, all added power taking transfer output shaft (and make and do not have, also can gearbox power taking mouth install the power taking axle box additional and the output of engine power transfer).Link to each other with generator 1 in the utility model by power taking transfer output shaft.After the destination is reached by Operation Van, use clutch that driving system and engine power system are broken away from.Engine drives generator 1 and rotates, the alternating current that is sent by generator 1 is after dry-type rectifier spare 3 is converted to direct current, under the conversion of the numerical controlled voltage of central control computer 10 control and convertor assembly 4, become the needed alternating current of load, and be assigned to each power consumption equipment through distribution board 2.

The utility model is when work, by central control computer 10 unified controls.Under software control, central control computer 10 adopts scan modes, regularly sends measurement adaptation module 11 that gating and voltage or current sensor 6 link to each other with 7 or 12 address gating signal by the standard serial communication interface.Standard industry interface 9 base areas select the signal value gating to measure adaptation module 11 or 12 accordingly.Measure adaptation module 11 or 12 by behind the gating, send back to central control computer 10 the analog quantity that is obtained by transducer is counter after the A/D conversion.Central control computer 10 compares according to value that records and the standard controlling models that deposits in, adjusts the Control Parameter that it is controlled numerical controlled voltage and convertor assembly 4, numerical control throttle control 8.For example when adjusting the parameter of numerical controlled voltage and convertor assembly 4, central control computer 10 sends the address gating signal of gating control adapter module 13 by the standard serial communication interface.Standard industrial control 9 is pressed the value gating control adapter module 13 of address gating signal.Behind gating, central control computer 10 sends control corresponding parameters number amount again, latchs and change the driving pulse frequency and the pwm value of its output by control adapter module 13, to reach the purpose of adjusting output AC piezoelectric voltage and frequency.When need are adjusted the running parameter of its engine, after central control computer 10 sends by the standard serial communication interface that gating links to each other with numerical control throttle control 8 and the adaptive mould of its control of controlling is joined 14, central control computer 10 sends new Control Parameter numerical value again, is latched and through the execution of D/A conversion rear drive numerical control throttle control 8 by control adapter module 14.Reach and change the purpose of sending out merit machine operating mode.

In the utility model owing to use numerical controlled voltage and convertor assembly to realize the output of alternating current, parameters such as the ac frequency of its output, voltage are all by controlling by shared central control computer, and generator generates electricity and can be rectified into direct current immediately, thereby require very loose to the rotating speed control of generator, need not special-purpose engine drives, can adopt and use the engine of Operation Van self to do power source, cancel the engine of special-purpose open-air generating equipment in the past, simplified the structure of power-supply device greatly.Output voltage also is by the control of numerical controlled voltage and convertor assembly in the utility model, does not need to adjust the excitation of generator, thereby can use efficiently that rare-earth synchronous motor has reduced the size of generator as generator, has simplified control.Use the engine of Operation Van self can also obtain bigger power output.
