Test method and system for reducing interference of mobile industry processor interfaces (MIPI)

Abstract

The invention discloses a test method and system for reducing the interference of mobile industry processor interfaces (MIPI). The test method includes the following steps that: when a tested terminal establishes communication, current communication frequency is obtained, the first preset frequency of a first interface type of mobile industry processor interfaces in mobile industry processor interfaces which work currently is obtained, wherein the first preset frequency is the default work frequency of the first interface type of mobile industry processor interfaces; the first preset frequency is compared with the communication frequency, and whether the first preset frequency is in the frequency band of the communication frequency is judged; and when the first preset frequency is not in the frequency band of the communication frequency, the first preset frequency is adopted as the current work frequency of the mobile industry processor interfaces. With the test method and system provided by the technical schemes of the invention adopted, the interference of mobile industry processor interfaces in a terminal communication process can be reduced, and user experience can be improved.

Description

technical field [0001] The invention relates to the field of electromagnetic interference, in particular to a test method and system for reducing MIPI interference. Background technique [0002] The data transmission speed between smart terminals and peripherals is getting faster and faster. Currently, the mainstream smart terminals on the market, such as smart phones, all adopt the MIPI communication mode of the processor interface of the mobile communication industry. When the user communicates, because the frequency of MIPI is very high, basically up to hundreds of MHz, the MIPI at this time can easily cause interference to the communication, affect the normal communication of the user, and reduce the user experience. At present, the processing of MIPI is in the research and development stage of the product. If the user encounters MIPI interference when using the terminal after it is put into the market, this interference is irreversible and the terminal cannot be automat...

Problems solved by technology

When users communicate, because the frequency of MIPI is very high, basically up to hundreds of MHz, MIPI at this time can easily cause interference to communication, affect the normal communication of users, and reduce the user's sense of experience

At present, the processing of MIPI is in the research and development stage of the product. If the terminal is put into the market and users experience MIPI interference when using it, this interference is irreversible and the terminal cannot be automatically eliminated.

Based on the above-mentioned series of problems, how to effectively reduce the electromagnetic interference of MIPI before the terminal leaves the factory, and avoid the inconvenience caused by the interference of MIPI to user communication after the terminal is put into the market, is an urgent problem for relevant researchers to solve
