When the vehicle encounters such faults, the fault parts are quickly detected and distinguished, the labor intensity of maintenance personnel is reduced, the maintenance time is saved, and the misjudgment rate is reduced.
Description
Technical Field
The utility model relates to a machine-building technical field especially relates to a mine car oil mass sensor and pencil fault detector.
Background
At present, when the fuel gauge indication is inaccurate or other indication state faults occur in a vehicle, most maintenance personnel firstly replace a fuel quantity sensor to remove the faults, if the faults exist at all, the faults can be replaced one by adopting a removal method, good parts after replacement can be abandoned, so that resources are wasted, claim loss is brought to a supplier, and even disputes of judgment errors can be generated.
The fuel gauge indicates a fault, and the parts are divided into three parts: oil mass sensor, relevant pencil connector, indicating instrument etc.. Generally, when an oil quantity indication fault occurs, a maintenance worker firstly replaces an oil quantity sensor for testing, if the fault still exists, other fault parts are searched along a line to replace related parts, maintenance time is relatively increased, maintenance cost is relatively increased, replaced parts are abandoned after the fault is eliminated, and therefore not only can resource waste be caused, but also claim loss can be brought to suppliers, and related disputes can be caused when the misjudgment rate is high.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the problem of in the present vehicle maintenance process, judge by mistake spare part that exists in the trouble shooting of oil mass indication is solved.
In order to solve the technical problem, the utility model discloses a realize according to following mode:
a mine car oil mass sensor and wire harness fault detector comprises a shell (1), an operating button (2), a wire harness instrument fault detection connector (3), an oil mass sensor fault detection connector (4), a status indicator lamp (5), a charging circuit board (6), a rechargeable lithium battery (7) and a detection function circuit board (8);
the USB charging interface is connected with the rechargeable lithium battery (7) through the charging circuit board (6); the detection function circuit board (8) is respectively connected with the rechargeable lithium battery (7), the wiring harness instrument fault detection connector (3) and the oil mass sensor fault detection connector (4); the shell (1) is provided with the operating button (2) and the status indicator lamp (5), and the operating button (2) and the status indicator lamp (5) are respectively connected with the detection function circuit board (8).
The utility model has the advantages that: compared with the prior art, this device distinguishes the trouble position fast at the vehicle maintenance in-process, reduces maintenance duration, reduces maintenance personal's intensity of labour, reduces the erroneous judgement rate, reduces the claim loss of accessory. The built-in rechargeable battery integrated structure is adopted, and the battery does not need to be replaced.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, a mine car fuel level sensor and pencil fault detector, including shell 1, operating button 2, pencil instrument fault detection connector 3, fuel level sensor fault detection connector 4, status indicator lamp 5, charging circuit board 6, rechargeable lithium cell 7 and detection function circuit board 8.
The USB charging interface is connected with a rechargeable lithium battery 7 through a charging circuit board 6, and the lithium battery is charged through an external power supply. The detection function mainboard 8 is respectively connected with the wiring harness instrument fault detection connector 3 and the oil mass sensor fault detection connector 4, the operation buttons 2 are used for fault detection classification selection, and the status indicator lamps 5 are used for indicating fault positions.
If the vehicle fuel gauge indicates a fault, firstly, the connector of the fuel gauge sensor and the connector of the wire harness are pulled down, the connector of the wire harness end is inserted into the wire harness instrument fault detection connector end of the fault detector, a vehicle key switch is turned on, the operation button 2 of the detector is pressed to select the fault detection state of the wire harness instrument, the detection function is started, the detector sends an output signal of the analog fuel gauge sensor to the instrument, and if the vehicle fuel gauge indicates that the meter gradually moves from 0 position to full position, the output signal gradually moves from the full position to 0 position. And if the middle is uninterrupted, the instrument and the wire harness are normal, otherwise, the line and the instrument are in fault.
With oil mass sensor's connector, insert the oil mass sensor fault detection connector port 4 of detector, detect the function with the detector and select oil mass sensor fault detection mode, from the bottom up or from the top down move oil float's position on, the pilot lamp on the detector can light on one by one according to oil float's position, if the pilot lamp is lighted in succession and is explained oil mass sensor normal, otherwise explains oil mass sensor trouble, if the connector contact is bad, the fault indicator lamp can flash.
When the oil mass indication fault occurs, the detector is firstly butted with the wire harness to detect whether the wire harness and the instrument are normal, if the fault occurs, the oil mass sensor is not required to be dismounted to directly detect the wire harness or the instrument, and if the wire harness and the instrument are normal, the oil mass sensor can be dismounted to detect, so that the fault part can be rapidly distinguished, the curved path of the replacement part test is omitted, the fault judgment is accurate, and the maintenance time is saved. The detector has the functions of judging faults of the wire harness and the instrument and judging faults of the oil sensor.
The present invention is not limited to the above-mentioned preferred embodiments, and any person can obtain other products in various forms under the teaching of the present invention, but any change in shape or structure is made, and all the technical solutions identical or similar to the present invention are within the protection scope of the present invention.
