Test system and method for standby current of mobile terminal

Abstract

The invention discloses a testing system and a testing method for a standby current of a movable terminal; the testing system includes a sampling resistance, a multimeter, a power and a movable terminal which are connected in series for forming a testing loop as well as a data collector connected in parallel with the sampling resistance; the invention further includes a comprehensive measuring device connected with the movable terminal and a shielding box which shields the movable terminal inside the shielding box. During testing, the movable terminal is arranged in a testing network environment and the movable terminal is started into a standby state; then the testing is started, the voltage at the two ends of the sampling resistance connected in series with the movable terminal is collected in real time by the data collector; the voltage data of the whole standby measuring process is preserved; after the measurement is finished, a real time standby current value in the whole standby process is obtained according to the relation formula of the voltage that I is equal to U / R; and the average standby current value during the standby measuring process is further obtained by an integral mean of (1 / t) multiply the integral of f from 0 to t. The invention has the advantages of high technical precision, high flexibility and being capable of tracing the state change of a mobile phone terminal.

Description

technical field [0001] The invention relates to the technical field of parameter measurement of a mobile terminal, in particular to a test system and method for a standby current of a mobile terminal. Background technique [0002] With the rapid development of wireless communication, mobile terminals with communication functions have attracted attention as a fast and convenient means of wireless communication, and their powerful functions, rich services, and personalized services have been recognized and favored by people. The research and development quality of mobile terminal is the starting point of each mobile terminal manufacturer. To ensure the more durable work of mobile terminal is also the main point and hot spot of their competition. Therefore, the control of the standby current of mobile terminal has become the key to the success of mobile terminal. Therefore, the test of standby current has become the first hurdle to verify the quality of mobile phones, and it is...

AI Technical Summary

Problems solved by technology

[0004] (1) The method of connecting the multimeter in series to measure the standby current is to average the standby current within the test time, and the accuracy is not high enough;

[0005] (2) These two previous test methods have poor flexibility in different test requirements;

[0006] (3) The standby current test method of connecting a multimeter in series has only one final average value, which cannot track the change of the standby current of the mobile phone terminal in real time;

[0007] (4) Use a multimeter to measure, if the average value of the standby current is required, the real-time change of the entire process current cannot be observed. Even if the multimeter is not set to the AVG position, only one change of the current can be seen and the data cannot be recorded, so it cannot be tracked Changes in the status of the mobile terminal

[0008] In view of the shortcomings of existing testing techniques such as low precision, poor flexibility, and the inability to track changes in the status of mobile phone terminals, a more accurate standby current testing method and system are needed to achieve high-precision, high-flexibility real-time measurement
