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
The present invention relates to a kind of detection field of card machine internal sensor, specifically a kind of device and method detecting card machine internal sensor state.
Background technology
Self-help terminal equipment is generally made up of man-machine interface, is operated according to device prompts by user.Such as ATM in bank, subway ticket machines etc. are self-help terminal equipment.The invention of self-help terminal equipment, facilitates trip and the service of people widely.In addition, also there is self-help terminal equipment in some supermarkets, sales field, such as reward voucher inquiry printer, bank queuing machine etc.
Self-help terminal equipment forms mutual environment by the multimedia database such as film, picture, word, music, thus be used for specially storing information and provide various information to inquire about, print, the electronic message unit of the service function such as payment and product sell.
Self-help terminal equipment mainly comprises: 24 hours integrated service self-service acceptance system and series electronic equipment and the system software such as equipment, business hall distribution of multimedia information and self-service query system, the self-service experience equipment of business hall new business, business hall queue management system, window services evaluator, LED display, be widely used in the industries such as communication, finance, government, traffic, medical treatment, industry and commerce, the tax at present.
The parts card machine of the use in existing self-help terminal equipment, card machine is the machine of plug-in card.Card machine internal sensor can not precise numberization detect, and because infrared ray launched by card machine internal sensor, along with the prolongation of service time, reflection potential declines thereupon.Owing to inciting somebody to action under emissive ability, receive judgement and tanglewrack, cause card machine to use and play pendulum.
Summary of the invention
Technical assignment of the present invention is for above weak point, provides a kind of device and method detecting card machine internal sensor state.Solution cannot the problem of state of rapid detection card machine internal sensor.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of device detecting card machine internal sensor state, comprise card machine internal sensor, CPU, display device, the power valve of card machine internal sensor connects power supply by resistance, power valve exports through filtering circuit filtering, the filtering output end of sensor is connected to the AD pin of CPU, and CPU is connected to display device.
Display device is 4 Digital sum pipes.
The filtering output end of sensor is connected to the 10th the AD pin of CPU.
Detect a method for card machine internal sensor state, adopt any one above-mentioned device to detect card machine internal sensor state, comprise the steps:
(1), the power valve of card machine internal sensor connects power supply by resistance, and power valve is launched, and receiving tube receives, and exports through filtering circuit filtering;
(2), the filtering output end of sensor is connected to the AD pin of CPU, and CPU works in the state reading AD pin;
(3), CPU will deliver to display device display after the currency process of reading;
(4), display device shows the numerical value of current sensor;
(5), card machine internal sensor state is judged by the display of display device.
Compared to the prior art a kind of device and method detecting card machine internal sensor state of the present invention, has the following advantages:
1, by numerical value digitizing, the state of energy rapid detection card machine internal sensor;
2, by detecting that the luminotron of the sensor that emissive ability are weak is changed in advance, ensure that card machine normally uses;
3, increase the service time of card machine, reduce maintenance time, enhance product performance.
