Abstract

The invention relates to a comprehensive test module controller for a generator and a starter of an automobile, and is test equipment for electric appliances of the automobile. An inner circuit is combined by a microprocessing chip and a special chip for PWM pulse width modulation; an outer circuit is provided with an overcurrent protection loop, a working condition selection loop and a voltage selection loop; input direct current voltage is divided into two grades of 12V and 24V; regulating range of output current can be divided into two grades of between 0 and 200A and between 0 and 500A; speed regulation ratio is 1 to 60; and input current of control loop is less than 1A. As a circuit combined by the microprocessing chip and the special chip for the PWM pulse width modulation is adopted, a signal processing, sampling protection and a drive circuit is more perfect and reliable; and simultaneously, energy-efficiency conversion ratio is improved. The controller has large current regulation range, simple circuit control, small size, and light weight, does not occupy spatial position, has low electricity consumption, is provided with a test working condition selection loop and the voltage selection loop, can meet requirement on comprehensive test of the generator and the starter of the automobile, and better solves the problems that the prior automobile generator test equipment and the prior automobile starter test equipment have insufficient comprehensive testing functions.

Description

Automobile current generator, starter motor experiment module controller

Technical field

The present invention relates to manufactruing equipment of automobile, be specially the car electrics testing equipment.

Background technology

At present, the delivery test of automobile current generator, the delivery test of automobile starter all needs the delivery test of the testing equipment through special use, particularly automobile starter, because the starting characteristics test torque request is very big, need powerful driver to finish startup, because the load current of driver itself is very big, and also heavy, not only loss own is high-power, and the manufacturing cost of itself is also very big; And the delivery test of automobile current generator is put a whole set of testing equipment again in addition. so there is function singleness in present car electrics testing equipment, power consumption is big, the high deficiency of cost.

Summary of the invention

It is little that the object of the invention provides a kind of volume, and the output power range of adjustment is big, and self power consumption is few, can satisfy automobile current generator test exciting current and regulate requirement, also can satisfy the experiment module controller that the regulation and control of automobile starter test driving power require.

The object of the present invention is achieved like this, and tentative module controller, interior circuit adopt little process chip composition that combines with PWM width modulation special chip; External circuit is provided with the overcurrent protection loop, and operating mode is selected the loop, and voltage is selected the loop; Input direct voltage divides 12V and two kinds of grades of 24V, and the output current regulating scope can be divided 0-200A and two kinds of grades of 0-500A, speed ratio 1:60, and the control loop input current is less than 1A.

Good effect of the present invention is: the tentative module that adopts little process chip to combine with PWM width modulation special chip is formed controller, the Current Regulation scope is big, control circuit is simple, volume own is little, in light weight, the position does not take up space yet, and power consumption own is low, being provided with operating condition of test again selects loop and voltage to select the loop, can satisfy the compbined test requirement of automobile current generator and automobile starter, overcome the problem of existing automobile current generator testing equipment and automobile starter testing equipment compbined test insufficiency of function preferably.

Description of drawings

Accompanying drawing is automobile current generator, automobile starter experiment module controller circuit diagram.

Among the figure, tentative module controller 1, starter motor 2, generator 3, mode switch 4, voltage-selected switch 5, battery pack 6, major loop protector 7, control loop protector 8, fine setting 9, earthing pole 10, electronic switch 11.

Below in conjunction with accompanying drawing, the invention will be further described:

In the accompanying drawing, in tentative module controller 1, binding post 1 is connected with an end of electronic switch 11, and binding post 2 is connected with the sliding contact of fine setting 9, and binding post 3 is connected with the fixed contact of fine setting 9; Main terminal B-is connected with earthing pole 10 with total negative pole of electric battery; The extension line of main terminal B+ is connected with an end of major loop protector 7, and other end extension line is connected with the moving contact of mode enable switch 4 centres; Main electrical scheme stake A2 is connected with the drive coil earthing pole of the total negative pole of electric battery, generator 3, the actuating coil earthing pole of starter motor 2; The actuating coil of starter motor 2 is anodal to be connected with the right stationary contact of mode enable switch 4; Main electrical scheme stake M-is the standby wiring pile that power is adjusted, and another utmost point of electronic switch 11 is connected with an end of control loop protector 8; After the other end parallel connection of major loop protector 7 and control loop protector 8, be connected with the moving contact of voltage-selected switch 5; The left stationary contact of voltage-selected switch 5 is connected with the mid point of two groups of 12V battery series connection of electric battery 6, and the right stationary contact of voltage-selected switch 5 is connected with total positive pole of electric battery 6.Main electrical scheme stake M-for the standby wiring pile that power is adjusted, realizes the power adjustment with main electrical scheme stake B-conversion wiring.

By accompanying drawing as can be known, tentative module controller loop works principle is: battery pack 6 provides 12V and two kinds of grade DC power supply of 24V to press selector switch 5 to select, after voltage-selected switch 5 is selected electric pressure according to testing requirements, main circuit current is by the main terminal B+ of major loop protector 7 to tentative module controller 1, at this moment, mode switch 4 is converted to the main circuit positive pole of tested galvanoscopic starter motor 2 or generator 3, and the main circuit negative pole of starter motor 2 or generator 3 enters tentative module in the controller 1 by main electrical scheme stake A2; At this moment; the control loop electric current is by the binding post 1 of control loop protector 8 to electronic switch 11 to tentative module controller 1; be connected with the interior circuit of tentative module, the interior circuit of tentative module is adjusted output characteristics by regulating fine setting 9, thereby realizes the control to tested electroscope input current.
