To be shown by display screen, can also be reported by loudspeaker.When control unit determines that subscriber identification card breaks down
Or during damage, the information of subscriber identification card damage or failure can be sent, facilitates user to understand subscriber identification card
State, changed.
In detection process, if subscriber identification card feed back to control unit feedback information and control unit in preset
Presupposed information difference when, it is pre- in control unit receives from subscriber identification card in other words feedback information and control unit
During the signal sequence difference first stored, then user is restarted after subscriber identification card, such as 5 seconds are restarted after preset time period
Identification card, if the subscriber identification card after restarting is still abnormal, it is determined that drive the hardware of subscriber identification card to go out
Existing failure, the information of hardware failure can be sent by Tip element, so that user repairs.And user's body after restarting
When part identification card normally starts, then it can determine to drive the software level of subscriber identification card low, Tip element can be passed through
The low information of software level is sent, so that user upgrades to software.
In summary, whether can be gone out with quick detection is that subscriber identification card breaks down or damaged in itself, so as to
Family is operated accordingly, can quickly solve the problems, such as subscriber identification card hot plug exception.Carried out without maintenance personal
Various blind debugging are gathered, and without depot repair, save time and cost.
