Detection method and device using current clamp and computer equipment

Abstract

The invention discloses a detection method and device using a current clamp and computer equipment, the detection method using the current clamp is applied to diagnosis equipment, and the detection method using the current clamp comprises the following steps: obtaining vehicle information of a to-be-detected vehicle; the data reading module is connected with a fault device of a to-be-detected vehicle to read current and voltage data of the fault device; performing comparative analysis on the current and voltage data and preset circuit standard data to generate a current and voltage analysis table; judging whether a circuit of a fault device of the to-be-detected vehicle has a fault according to the current and voltage analysis table; if the judgment result is yes, searching a historical diagnosis record of the same type of vehicles matched with the fault device of the to-be-detected vehicle from a database to obtain a maintenance scheme; the current clamp can be used for detection without professional maintenance personnel, the detection efficiency is high, fault judgment is accurate, a correct maintenance scheme is provided, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of automobile diagnosis, in particular to a detection method, device and computer equipment using a current clamp. Background technique [0002] The system circuit failure will inevitably occur during the use of the car. Usually, the current clamp is used to read the current and voltage value of a certain device, and then the maintenance personnel judge whether the circuit of the device is faulty according to the current and voltage value, but there is no A definite standard value is mostly based on the maintenance personnel's own maintenance experience to judge whether the current and voltage values ​​are normal, so as to judge whether the circuit of the automotive device is normal. [0003] Most of the maintenance shops and 4S shops on the market are maintenance personnel who use current clamps to detect device circuit failures. When maintenance personnel are inexperienced or users do not know whether the ...

[0002] The system circuit failure will inevitably occur during the use of the car. Usually, the current clamp is used to read the current and voltage value of a certain device, and then the maintenance personnel judge whether the circuit of the device is faulty according to the current and voltage value, but there is no A definite standard value, most of which are based on the maintenance personnel's own maintenance experience to judge whether the current and voltage values ​​are normal, so as to judge whether the circuit of the automotive device is normal

[0003] Most of the maintenance shops and 4S shops on the market are maintenance personnel who use current clamps to detect device circuit failures. When maintenance personnel are inexperienced or users do not know whether the current and voltage values ​​are normal, they cannot judge the device circuit of the car. Whether it is normal or not affects efficiency
