Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] The electronic product with NFC function in this embodiment is mainly composed of NFC sensing circuit, light emitting diode LED, DC power supply U, switch tube Q1, etc., see figure 1 As shown, wherein, the DC power supply U supplies power for the system of the electronic product, the light-emitting diode LED and other electrical devices in the electronic product. The sensing signal output by the sensing signal output terminal P1 of the NFC sensing circuit is transmitted to the system of the electronic product, and the system of the electronic product controls the NFC function module to realize the corresponding function according to the sensing signal received. The sensing signal output terminal P1 of the NFC sensing circuit is connected to one end of the conduction path of the switch tube Q1 through the light emi...

Abstract

The invention discloses an electronic product with an NFC function. The electronic product comprises an NFC sensing circuit, an LED and a DC power source. The DC power source supplies power to a system of the electronic product and the LED, the system signal input end of the electronic product is connected with the LED through a driving circuit, and sensing signals output by the sensing signal output end of the NFC sensing unit are transmitted to the system of the electronic product. The electronic product further comprises a switch tube, the sensing signal output end is connected to one end of a connecting passage of the switch tube through the LED, the control end of the switch tube is connected with the DC power source, and the other end of the connecting passage of the switch tube is connected to the ground. According to the electronic product with the NFC function, after power outage and shutdown, when external NFC equipment is close to or in contact with the electronic product, whether the NFC sensing circuit generates sensing signals or not is detected by the way of whether the LED emits light or not, simpleness and convenience are achieved, the LED is an original device in the electronic product, and therefore the cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to an electronic product with NFC function. Background technique [0002] At present, there are more and more electronic products with NFC functions, and various functions can be realized through the NFC technology. In order to ensure the normal use of the NFC function, it is necessary to frequently detect the power supply of the electronic product. [0003] When the external NFC device is close to or touches the NFC sensing area of ​​the electronic product, if the electronic product can realize the corresponding function, it means that the power supply of the electronic product is normal; if the corresponding function of the electronic product is not realized, the power supply of the electronic product cannot be judged Whether the power supply is normal or not, at this time, the user usually needs to perform additional operations to judge the fault problem...
