[0066] In order to solve the problem of abnormal reading of the terminal card in the existing solution, the terminal must be disassembled when the fault is detected. The disassembly detection is not only inefficient, difficult and easy to cause damage, but also brings distrust to users. , This embodiment provides a terminal card abnormality detection device. For details, see figure 2 .

[0067] The device includes a card socket S203, a central processing unit S201, a power management chip S202, a level path control element S204, a first data path control element S206, a second data path control element S207, and a data interface S205.

[0068] The device is divided into a power supply module and an abnormality detection module. In the power supply module, the power management chip supplies power to the card socket and the central processing unit; the abnormality detection module is as follows:

[0069] The terminal card is placed on the card socket S203, and some pins of the termina...

[0086] In order to solve the problem of abnormal reading of the terminal card in the existing solution, the terminal must be disassembled when the problem needs to be detected. The disassembly detection is not only inefficient, difficult and easy to cause damage, but also brings distrust to users. , This embodiment provides a method for detecting abnormality of a terminal card. For details, see Figure 4 .

[0087] The terminal card abnormality detection method of this embodiment includes:

[0088] S401: The terminal determines that the card recognition fails and receives a control signal;

[0089] S402. The first GPIO port outputs the first potential according to the control signal, and the second GPIO port outputs the second potential according to the control signal;

[0090] S403. The first data path control element and the second data path control element receive the second potential output by the second GPIO port, and turn off the first data path control element and the second da...

Abstract

The invention discloses a terminal card anomaly detection device and method, a terminal and a readable storage medium. The terminal card anomaly detection method comprises the following steps: when aterminal has card reading abnormality, connecting a level path between a terminal card pin and a central processing unit with a first data path through a control level path control element; maintenance personnel can measure a voltage value in the first data path through external equipment, to detect a line causing abnormal card reading. The effect that the terminal can detect the line causing abnormal card reading under the condition of not carrying out disassembly operation is realized. The invention further discloses a terminal and a computer readable storage medium. By implementing the scheme, the problems that in the prior art, when card reading of the terminal is abnormal, disassembly detection needs to be carried out, so that the detection efficiency is low, the difficulty is high, damage is likely to be caused, and meanwhile, a user feels untrusted are solved.

Description

Technical field [0001] The technical field of the terminal of the present invention, more specifically, relates to a terminal card abnormality detection device, method, terminal and computer readable storage medium. Background technique [0002] At present, after a normal terminal card is inserted into the terminal, if there is a problem that the card cannot be recognized, a maintenance engineer needs to disassemble the terminal, and then observe the structure of the card socket and perform necessary inspections to determine the source of the problem. Since this operation requires disassembly of the terminal, the disassembly detection is not only inefficient, difficult and easy to cause damage, but also brings distrust to the user. Summary of the invention [0003] The present invention provides a terminal card abnormality detection device, method, terminal and computer readable storage medium, which aim to solve the reason why the terminal card needs to be disassembled and detect...
