Problems solved by technology

[0008] When the existing circuit is powered off, if the IC card is powered off again during the data recovery process, it is likely to cause incomplete card data recovery, or even a recovery error, and the existing single-command power-off test has no Card design defects cannot be detected; at the same time, if the circuit fails, the power cannot be cut off; it will not be notified in time, resulting in energy waste
[0009] Traditional 6T SRAM memory cells can achieve both stability and area cost at high operating voltages. However, driven by the requirement to reduce power consumption, as the minimum operating voltage gradually decreases, it is difficult to write data into memory cells. Or writing data fails, and as VDD drops, the static noise margin also drops, and the stability of the memory cell is threatened under low voltage conditions

Abstract

The invention belongs to the technical field of circuit power-off, and discloses an intelligent circuit and a method for controlling power-off. The intelligent circuit for controlling power-off comprises a power supply module, a current detection module, a voltage detection module, a main control module, a circuit monitoring module, a power-off test module, an alarm module and a display module. The circuit comprises a power supply module, a current detection module, a voltage detection module, a main control module, a circuit monitoring module, a power-off test module and a display module. Theinvention solves the problem that the existing single instruction power-off test can not detect whether the power-off protection mechanism is correct when the card executes data recovery or not through the power-off test in the execution process of writing data instructions to the smart card by the power-off test module and the power-off test in the execution process of the data recovery instructions. At the same time, through the circuit monitoring module, the alarm module can detect circuit faults in time, and send out a warning sound to remind the staff to do a good job of protective measures.

Description

technical field [0001] The invention belongs to the technical field of circuit power-off, and in particular relates to an intelligent circuit and method for controlling power-off. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The circuit is the path through which the current flows, or electronic circuit, which is composed of electrical equipment and components; connected in a certain way. Such as resistors, capacitors, inductors, diodes, triodes, power supplies and switches, etc., constitute a network. The size of the circuit can vary greatly, from as small as an integrated circuit on a silicon chip to as large as a high-voltage and low-voltage transmission network. According to the different signals processed, electronic circuits can be divided into analog circuits and digital circuits. However, when the existing circuit is powered off, if the card is powered off again during the data recovery ...
