Diagnosis method and device for charging pile

Abstract

The invention discloses a diagnosis method and device for a charging pile. The diagnosis method for the charging pile comprises the following steps: determining a safety threshold range of electric signal data of each monitoring point in the charging pile; acquiring electric signal data of each monitoring point in real time; judging whether the electric signal data of each monitoring point is within a corresponding safety threshold range or not, and if not, determining that the corresponding electric signal data is abnormal data; whether the charging pile is in a controlled charging state or not is detected, if yes, it is determined that abnormal data is abnormal data, and if not, it is determined that the abnormal data is fault data; judging whether a diagnosis rule corresponding to the abnormal data or the fault data exists or not, if yes, determining a generation reason and a solution of the abnormal data or the fault data according to the corresponding diagnosis rule, and if not, generating diagnosis-rule-free information; and sending the generation reason and the solution or the non-diagnostic rule signal to a server side. According to the technical scheme provided by the embodiment of the invention, the utilization rate of the charging pile is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of charging piles, and in particular, to a method and device for diagnosing charging piles. Background technique [0002] With the rapid development of the new energy industry and the government's strong support for the new energy industry, the new energy vehicle industry has developed rapidly, and it has also driven the rapid development of the matching charging pile industry. [0003] Charging piles may fail during actual use, and there are various reasons for the failures. On-site operation and maintenance personnel will spend a lot of time in the process of troubleshooting, which is not conducive to the effective use of charging piles. In order to solve the above problems, an automatic detection equipment for faults is proposed in the prior art, but the automatic detection equipment detects and provides corresponding solutions after the charging pile fails, and cannot detect abnorma...

Problems solved by technology

[0003] Charging piles may fail during actual use, and there are various reasons for the failure. On-site operation and maintenance personnel will spend a lot of time in the process of troubleshooting, which is not conducive to the effective use of charging piles

In order to solve the above problems, an automatic detection equipment for faults is proposed in the prior art, but the automatic detection equipment detects and provides corresponding solutions after the charging pile fails, and cannot detect abnormal data during the charging process, and cannot be eliminated in time Abnormal data reduces the probability of failure, so the utilization rate of charging piles has not been effectively improved
