Abstract

The invention discloses a device and a method for detecting the state of a card machine internal sensor, and belongs to the field of card machine internal sensor detection. The invention aims to solve the problem that the state of a card machine internal sensor cannot be detected quickly. The technical scheme is as follows: the device for detecting the state of a card machine internal sensor comprises a card machine internal sensor, a CPU, and a display device; a transmitting tube of the card machine internal sensor is connected with a power supply through a resistor; the transmitting tube carries out output after filtering through a filtering circuit; and the filtering output end of the sensor is connected to an AD pin of the CPU, and the CPU is connected to the display device. The method for detecting the state of a card machine internal sensor comprises the following steps: the filtering output end of the sensor is connected to the AD pin of the CPU, and the CPU works and reads the state of the AD pin; the CPU processes the read current value and sends the value to the display device for display; the display device displays the current numerical value of the sensor; and the state of the card machine internal sensor is judged through display of the display device.

Description

technical field [0001] The invention relates to the detection field of a card machine internal sensor, in particular to a device and method for detecting the state of the card machine internal sensor. Background technique [0002] Self-service terminal equipment is generally composed of a man-machine interface, which is operated by the user according to the prompts of the equipment. For example, bank ATM machines and subway ticket machines are all self-service terminal equipment. The invention of self-service terminal equipment has greatly facilitated people's travel and services. In addition, there are also self-service terminal equipment in some supermarkets and stores, such as coupon query printers, bank queuing machines, etc. [0003] Self-service terminal equipment is an electronic information equipment that forms an interactive environment through multimedia databases such as movies, pictures, text, and music, and is specially used to store information and provide va...
