Abstract

The invention relates to a starting current sensor for an automobile. The existing bus is generally poor in work state, and especially, fault points of a starting system are difficult to judge due to frequent starting, thus a bus driver hopes that the judgment mode can be direct and simple; and the existing bus drivers are frequently replaced, the buses are frequently regulated, the differences of the technical conditions of the buses are large, maintenance level is low, and management is lagged, so that the whole service level is affected by small errors. The starting current sensor for the automobile comprises a sensor and is characterized in that the sensor is successively connected with a pulse amplification circuit and a display circuit. The starting current sensor for the automobile has the advantages of visually displaying the magnitude of staring current, judging the work state of batteries, judging the work state of a starter, simplifying fault analysis and saving maintenance time.

Description

The automobile starting current sensor

One, technical field:

The present invention relates to a kind of automobile starting current sensor.

Two, background technology:

Present bus, the general work state is poor, and especially frequent startup to the judging point of start-up system, has certain difficulty, and the bus chaufeur is hoped directly and is oversimplified.

Present bus chaufeur, owing to change frequently, the bus adjustment is frequent; The engineering factor difference of automobile is bigger, and the maintenance level is low, adds the hysteresis of management; Often minor issue influences the single-piece level of service, if correct judgment; In 1-2 seconds, just can judge how next step should work, be flushing storage battery, active joint, or the storage battery electric weight is not enough or the like.

We be exactly solve bus application with decision problem and design-calculated helps correct judgement of bus chaufeur and correct handling, let the passenger wait for or change trains, to the judgement of maintainer's trouble point highly significant.

Three, summary of the invention:

The present invention is in order to solve the weak point in the above-mentioned background technology, provide a kind of simple in structure, can intuitively show the starting current size, can judge battery and starter motor mode of operation, can make that failure analysis is oversimplified, the time-saving automobile starting current sensor of maintenance.

For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of automobile starting current sensor, comprise sensor, and it is characterized in that: be connected with pulse amplifying circuit and display circuit on the described sensor in turn.

Compared with prior art, the advantage and the effect that have of the present invention is following:

The size that 1, can intuitively show starting current

2, can judge the mode of operation of battery

3, can judge the mode of operation of starter motor

4, failure analysis is oversimplified

5, practice thrift maintenance time

Four, description of drawings:

Fig. 1 is a structured flowchart of the present invention;

Fig. 2 is a circuit diagram of the present invention.

Five, the specific embodiment:

Referring to Fig. 1: a kind of automobile starting current sensor, comprise sensor 1, it is characterized in that: be connected with pulse amplifying circuit 2 and display circuit 3 on the described sensor 1 in turn.

Referring to Fig. 2: when automobile starting moment, starting current is generally at 100-200A, and diesel car is at 200--300 A;, be clipped in the sensor 1 that starts on the electric wire, inducing current and voltage are just arranged; The work of this electric current and the voltage aerotron BG1 in oversampling circuit is amplified, and promotes the relevant work (both indicating) of instrument, just can directly reflect the electric current that starts on the electric wire; The size of electric current directly reflects the good and bad of start-up system.

If actuating motor, when sky rotated, rotation height and the time was short, and working current is little, explain that storage battery and connection lead have problem, if electric current greatly, explain that actuating motor efficient is low, should keep in repair as early as possible and change.

If the electric current of actuating motor is big, and rotation explain that actuating motor has short circuit to exist, and should keep in repair and change as early as possible when low. or the like fault judgement simply and visualize, use more convenient.

The automobile starting current sensor adopts the integrated work of sensor module, as long as be clipped on the starting current lead; Or be enclosed within on the starting current lead; The starting current sensing that just can accomplish moment shows judge very easily starting current how much, thereby judges the mode of operation of start-up circuit; Make the judgement of mode of operation, become and to show and visualize.

Claims

1. an automobile starting current sensor comprises sensor (1), it is characterized in that: be connected with pulse amplifying circuit (2) and display circuit (3) on the described sensor (1) in turn.
