Abstract

The utility model relates to an oil level monitoring device, which comprises an oil amount horizontal line detection circuit and a singlechip control circuit, wherein an output signal of the oil amount horizontal line detection circuit is transmitted to the singlechip control circuit through an oscillation circuit; and an output signal of the singlechip control circuit is sent to a global system for mobile communication (GSM) transceiver module circuit. By the oil level monitoring device, light intensity is used as an oil level horizontal position acquired signal; and after the acquired signal is judged by a singlechip, a GSM module informs a vehicle owner through a short message to timely fill engine oil, so that an engineering mechanical vehicle can normally run.

Description

A kind of oil level supervising device

Technical field

The utility model relates to a kind of supervising device, particularly be a kind of oil level supervising device of engineering machinery.

Background technology

During the engineering machinery internal combustion engine long-time running, the inner machine oil of meeting loss in case machine oil is on the low side, finally can cause machine breakdown.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of oil level supervising device is provided.

The utility model solves the technical scheme that its technical matters adopted: a kind of oil level supervising device; Comprise oil mass horizontal line testing circuit and single chip machine controlling circuit; The output signal of said oil mass horizontal line testing circuit transfers to single chip machine controlling circuit through oscillatory circuit, and the output signal controlling of said single chip machine controlling circuit is sent to GSM transceiver module circuit.

Preferably; Said oil mass horizontal line testing circuit adopts the plexiglass rod L of a leaded light as fuel-quantity transducer; This plexiglass rod L is bonded on the oil mass scale; Place a pilot lamp LD on its top, a phototransistor T1 is installed in its bottom, the output terminal of said phototransistor T1 is connected with triode T2.

Preferably, said phototransistor T1 is installed on 1/2 inch place of plexiglass rod L bottom.

Preferably, said oscillatory circuit is made up of capacitor C 2 and the BT33 single crystals pipe T3 that triode T2 output terminal connects.

Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: the utility model adopts light intensity as oil level horizontal level acquired signal, after single-chip microcomputer is judged, passes through the car owner through the gsm module note; Should in time increase machine oil, guarantee the engineering machinery vehicle operation.

Description of drawings

Fig. 1 is the frame assumption diagram of the utility model;

Fig. 2 is the circuit theory diagrams of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further to specify.

Like Fig. 1, shown in Figure 2; A kind of oil level supervising device of the utility model; Comprise oil mass horizontal line testing circuit 1 and single chip machine controlling circuit 2; The output signal of said oil mass horizontal line testing circuit 1 transfers to single chip machine controlling circuit 2 through oscillatory circuit 11, and the output signal controlling of said single chip machine controlling circuit 2 is sent to GSM transceiver module circuit 21.

Said oil mass horizontal line testing circuit 1 adopts the plexiglass rod L of a leaded light as fuel-quantity transducer; This plexiglass rod L is bonded on the oil mass scale, places a pilot lamp LD on its top, and a phototransistor T1 is installed in its bottom; The output terminal of said phototransistor T1 is connected with triode T2; 1/2 inch (1.27cm) that said phototransistor T1 is installed on plexiglass rod L bottom locates, and said oscillatory circuit 11 is made up of capacitor C 2 and the BT33 single crystals pipe T3 that triode T2 output terminal connects, when oil mass reduces; Phototransistor T1 light intensity is strong more; Oil mass is big more, and it is big more to decay, and then the resistance that appeared of phototransistor T1 is also just big more.

When oil mass just often; The light intensity at phototransistor T1 place is attenuated, and the resistance value that phototransistor T1 is appeared is very big, makes triode T2 not have enough base biases and ends; Then BT33 single crystals pipe T3 oscillating part is not worked; This signal is input to the 36th pin I/O end of single-chip microcomputer IC1, after single-chip microcomputer IC1 internal processes is judged, does not send control signal.

In case during low on fuel, light decrement is little, phototransistor T1 receives the light saturation conduction; The dynamo-electric resistance of its c-e diminishes, and then the base potential of triode T2 raises, when oil mass drops to a certain limit value; Triode T2 saturation conduction makes the capacitor C 2 of single crystals pipe T3 can constantly discharge and recharge oscillator work; This signal is input to single-chip microcomputer IC1 the 36th pin I/O end, after single-chip microcomputer IC1 internal processes is judged, forms datel circuit by single-chip microcomputer IC1 the 1st, 2,3,12 pin and GSM transceiver module IC2, pull-up resistor R7-R10 etc.; IC1 sends data command by single-chip microcomputer, drives GSM transceiver module IC2 internal module, after GSM transceiver module IC2 decoding; Send warning message to operator on duty's mobile phone, explain that the machine oil oil level is on the low side.

An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
