Embodiments of the invention

 The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

 As shown in FIG. 1 , an embodiment of the present invention provides a method for determining a power-on state of a product. The power-on state of the product includes two states in which the product is in an energized state and the product is in a power-off state.

[0038] The method comprises the following steps:

 [0039] Step S101: The circuit of the product has an operating current, and the RA M of the first communication module placed in the product stores the first information, wherein the first information indicates that the product is in an energized state and can be recognized by the second communication module.

 [0040] RAM is an abbreviation for random access memory, which means random access memory in Chinese.

[0041] In step S101, the buffer for storing the first information in the RAM of the first communication module may be to write the first information according to the detection result of detecting whether the circuit of the product has an operating current, when the circuit of the product is detected. Having an operating current 吋, writing first information to the RAM of the first communication module, causing the RAM of the first communication module to store the first information; when detecting that the circuit of the product does not have the operating current 吋, not to the RAM of the first communication module Write the first message.

[0042] In this embodiment, the method for detecting whether the circuit of the product has an operating current may be at every preset. After the daytime, the circuit of the product is detected, such as detecting whether the circuit of the product has an operating current every Is; or when the first communication module initiates communication with the second communication module, whether the circuit of the product has an operating current. To perform the detection, since the two need to initiate communication to establish communication, if the circuit of the product has an operating current, before the first communication module establishes communication with the second communication module,

And writing the first information in the RAM of the first communication module, so that the RAM of the first communication module stores the first information.

 [0043] Of course, the downtime of storing the first information by the RAM of the first communication module may also be that the first information is written in the RAM of the first communication module during the process in which the circuit operating current of the product is not available. That is to say, after the product is powered on, the first information is written to the RAM of the first communication module, so that the R AM of the first communication module stores the first information.

 [0044] The RAM of the first communication module may be divided into specific areas for specifically storing the first information, or may be used to store the first information without using a specific storage area in the RAM.

[0045] The first information in step S101 is for indicating that the product is in the power-on state, and after the second communication module recognizes the first information, the second communication module determines that the product is in the power-on state.

[0046] Step S102: After the first communication module establishes communication with the second communication module, the RA of the first communication module

The first information in M is identified by the second communication module to cause the second communication module to determine that the product is powered.

 [0047] In step S102, the communication manner of the first communication module and the second communication module includes WIFI

 , NFC, RFID and Bluetooth. Of course, other communication methods can also be included.

 [0048] WIFI is an abbreviation of Wireless-Fidelity, its Chinese meaning is wireless network technology, NFC is Near

Abbreviation for Field Communication, its Chinese meaning is short-range wireless communication technology, RFID is the abbreviation of Radio Frequency Identification, and its Chinese meaning is radio frequency identification technology.

 [0049] After the second communication module establishes communication with the first communication module by using WIFI or Bluetooth, since the communication distance between the WIFI and the Bluetooth is long, the user holds the second communication module at a distance from the first communication module. Communicate, let users know more easily and quickly whether the product is powered. The second communication module may be a wearable device, a smart phone or a tablet.

[0050] For example, if the user wants to know whether the TV in the living room is in the open state in the bedroom, the second communication module of the mobile phone can be connected with the first communication module in the television, and it can be known whether the television is in the state of being turned on, and never Users need to go to the living room to know if the TV is in the open state.

[0051] The first communication module may be a radio frequency identification tag, and the RAM bit may be different for different radio frequency identification tags. For example, ST's M24LR04E-R model radio frequency identification tag adopts the EH_mode bit of the Configurati on byte register. The NXP's NT3H1101/NT3H1201 RFID tags use the PTHRU_ON_OFF bit.

[0052] In step S102, after the first communication module establishes communication with the second communication module, the first communication module may actively send the first information to the second communication module, or may be the second communication module to the first communication. The module requests to view the first information.

 [0053] If the second communication module identifies the first information in the RAM of the first communication module, it is used as a judgment criterion to determine that the product is in an energized state.

[0054] The method may further include the following steps:

 [0055] in the circuit of the product does not have an operating current, the RAM of the first communication module does not store the first information; [0056] after the first communication module establishes communication with the second communication module, the second communication module does not recognize the first The first information in the RAM of the communication module determines that the product is in a power down state.

[0057] The circuit of the product does not have an operating current 吋. If the RAM of the first communication module has an operating current in the circuit of the product, the first information is stored, and according to the storage characteristic of the RAM, the stored content is lost after the power is turned off.

That is, the RAM of the first communication module no longer stores the first information.

[0058] The second communication module establishes communication with the first communication module. Since the first information is not stored in the RAM of the first communication module, the second communication module does not recognize the first information, and then the second communication module determines the product. It is in a power off state.

[0059] The method may further include:

 [0064] The circuit of the product has an operating current 吋, and if the RAM of the first communication module is reset, the first information is written again in the RAM of the first communication module.

 [0065] when the RAM of the first communication module is reset, the first information is written to the RAM in the first communication module, so that the first information is stored in the RAM of the first communication module, and the second communication module is avoided. The circuit of the product has an operating current and the second communication module does not recognize the first information and generates a false positive.

 [0066] Of course, the method may further include:

 [0067] The circuit of the product has an operating current 吋, and after the single command in the communication process between the first communication module and the second communication module ends, the first information is written again in the RAM of the first communication module.
