Problems solved by technology

[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

Abstract

The invention discloses a detection method, device and computer equipment using a current clamp, which is applied to diagnostic equipment. The detection method using a current clamp includes the following steps: acquiring vehicle information of a vehicle to be tested; and connecting to a faulty device of the vehicle to be tested , to read the current and voltage data of the faulty device; according to the current and voltage data, compare and analyze with the preset circuit standard data to generate a current and voltage analysis table; judge the vehicle under test according to the current and voltage analysis table Whether there is a fault in the circuit of the faulty device; if the judgment result is yes, then search the historical diagnostic records of the same type of vehicle that matches the faulty device of the vehicle to be tested from the database to obtain a maintenance plan; the present invention does not require a professional The maintenance personnel can also use the current clamp for detection, which has high detection efficiency, accurate fault judgment and correct maintenance plan, which improves the user experience.

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] System circuit failures will inevitably occur during the use of the car. Usually, the current clamp is used to read the current and voltage values ​​of a certain device, and then the maintenance personnel judge whether the circuit of the device is faulty according to the current and voltage values. For a certain standard value, most of them are based on the maintenance experience of the maintenance personnel to judge whether the current and voltage values ​​are normal, so as to judge whether the circuit of the automobile device is normal. [0003] Most of the repair shops and 4S shops on the market use the current clamp to detect the circuit failure of the device. When the maintenance personnel are inexperienced or the user does not know whether the current and volt...
