SIM card fault detector and detection method

Abstract

The invention provides an SIM card fault detector comprising a detection end and an upper computer. The detection end comprises SIM card detectors, a fault indicating unit and a serial server. The detection end is provided with a power switch, a detection button, a reset button and the network interface of the serial server. The detection end is small in design, convenient to carry and convenientto use. Multiple SIM card detectors are summarized by using the serial server, the data of multiple SIM card detectors can be simultaneously processed and communication with the upper computer can beperformed through the serial server so that rapid and accurate detection can be realized.

Description

technical field [0001] The invention relates to a SIM card failure detector and a detection method. Background technique [0002] With the widespread use of the State Grid's intelligent collection terminals using GPRS technology, the SIM cards used to support them are also purchased on a large scale. These SIM cards come from China Mobile, China Unicom and China Telecom. During the on-site commissioning of the power grid, it is often found that the intelligent collection terminal is disconnected. Through investigation, it is found that a large part of it is caused by SIM card failure, some SIM cards are in arrears, and some SIM cards are internally damaged. Although these problems are very basic, for the grassroots staff of the power supply bureau, they don't know how to troubleshoot and troubleshoot the SIM card. In actual use, except for SIM card manufacturers and operators who have special SIM card testing equipment, other manufacturers have not made special tests for SI...

Problems solved by technology

During the on-site commissioning of the power grid, it is often found that the intelligent collection terminal is disconnected. Through investigation, it is found that a large part of it is caused by the failure of the SIM card. Some SIM cards are in arrears, and some SIM cards are internally damaged.

Although these problems are very basic, for the grassroots staff of the power supply bureau, they don't know how to troubleshoot and troubleshoot the SIM card

In actual use, except for SIM card manufacturers and operators who have special SIM card testing equipment, other manufacturers have not made special testing equipment for SIM cards.

However, the testing equipment of the SIM card manufacturer is too complicated to be used by grassroots workers.

If the mobile phone is used to detect the faults of the SIM cards one by one, the efficiency is too low
