Antenna anomaly detection method and device, equipment and storage medium

Abstract

The invention discloses an antenna anomaly detection method and device, electronic equipment and a computer readable storage medium, and the method is applied to wireless communication equipment, and comprises the steps: controlling each antenna to carry out scanning according to each frequency point in a frequency point list, and recording an obtained signal receiving strength value; comparing the difference between the signal receiving strength value of the current antenna at the current frequency point and the effective threshold value of the signal receiving strength of the wireless communication equipment; and if a difference value between the signal receiving strength value and the signal receiving strength effective threshold value reaches an antenna performance difference threshold value, judging that the current antenna is abnormal. According to the invention, under the condition of not additionally increasing circuit components, effective detection of various abnormal problems of the antenna is realized in a software detection mode, so that not only is the increase of circuit cost and layout space avoided, but also the detection capability and the detection efficiency of the abnormal condition of the antenna are effectively improved, and the user experience is greatly improved.

Description

technical field [0001] The present application relates to the technical field of antenna detection, and in particular, to a method, an apparatus, an electronic device, and a computer-readable storage medium for anomaly detection of an antenna. Background technique [0002] For current wireless communication products, the antenna is an essential communication component. Typically, the antenna is connected to the front-end feed point by soldering or connectors. In actual use, vibration or some other scenarios may cause the connection of the connection point to fail, thereby causing communication failure. Therefore, the diagnosis of antenna abnormalities is very important. [0003] In the current antenna detection scheme, a grounding resistor is usually set on the antenna, and a pull-up resistor is set on the module end of the communication product, so that the level of the antenna port can be used to identify whether the antenna connection is disconnected. Since this method...

AI Technical Summary

Problems solved by technology

Since this method requires additional resistors, the antenna needs to be specially customized, and the product side also needs specific circuit coordination, so the cost is high; at the same time, for wireless communication products with multiple antenna function ports, this method will obviously increase the size of the product circuit space

In addition, this method can only detect whether the antenna is connected successfully, but cannot effectively detect the damage and fastening effect of the antenna body
