Problems solved by technology

For this reason, these devices are generally equipped with batteries or still need an external power supply, and the power of the battery is limited, so that the service life of these devices is also limited. If the form of an external power supply is used, the range of use will inevitably be limited. limit

Embodiment 1

[0042] Such as figure 2 As shown, it is a schematic flow chart of a communication method in an embodiment of the present invention, and the method includes the following steps:

[0043] S101: the control device sends an instruction to communicate with the passive or low power consumption device to the RFID reader.

[0044] Specifically, the communication between the control device and the RFID reader may be through a wired connection, or through wireless communication, so that the control device sends an instruction to the RFID reader to communicate with a passive or low-power device. Wherein, the control device may send an instruction to communicate with a specified passive or low-power device, or may send an instruction to communicate with multiple passive or low-power devices.

[0045] S102: In response to an instruction to communicate with a passive or low-power device, the RFID reader sends a first radio frequency signal.

[0046] Based on the technical principle of RF...

Embodiment 2

[0065] The embodiment of the present invention also provides a communication system, such as figure 1 As shown, the system includes: control equipment, RFID readers and RFID tags, and passive or low-power devices.

[0066] A control device that sends instructions to the RFID reader to communicate with passive or low-power devices.

[0067] Specifically, the communication between the control device and the RFID reader may be through a wired connection, or through wireless communication, so that the control device sends an instruction to the RFID reader to communicate with a passive or low-power device. Wherein, the control device may send an instruction to communicate with a specified passive or low-power device, or may send an instruction to communicate with multiple passive or low-power devices.

[0068] An RFID reader for transmitting a first radio frequency signal in response to an instruction to communicate with the passive or low power device.

[0069] Based on the tech...

Embodiment 3

[0090] Such as Figure 6 As shown, it is a schematic structural diagram of a control device according to an embodiment of the present invention, and the device includes a control device 21 and an RFID reader 22 communicatively connected with the control device.

[0091] The control device 21 is configured to send an instruction to the RFID reader 22 to communicate with passive or low power consumption devices.

[0092] Specifically, the communication between the control device 21 and the RFID reader 22 may be through a wired connection or through wireless communication, so that the control device 21 sends an instruction to the RFID reader 22 to communicate with a passive or low-power device. Wherein, the control device 21 may send an instruction to communicate with a specified passive or low-power device, or may send an instruction to communicate with multiple passive or low-power devices.

[0093] The RFID reader 22 is configured to send a radio frequency signal in response ...

Abstract

The embodiment of the invention provides a communication method, device and system and electronic equipment. The method comprises the steps that control equipment sends an instruction for communicating with passive or low-power-consumption equipment to an FRID reader; in response to an instruction of communicating with the passive or low-power-consumption equipment, the FRID reader sends a first radio frequency signal; and the FRID tag outputs a first level signal to passive or low-power-consumption equipment bound with the FRID tag in response to the radio frequency signal so as to supply power to the passive or low-power-consumption equipment and communicate with the passive or low-power-consumption equipment. According to the embodiment of the invention, the RFID tag with the level output capability is utilized to realize the power supply of the active main control equipment to the passive or low-power-consumption equipment and the communication between the passive main control equipment and the low-power-consumption equipment, so that the passive or low-power-consumption equipment is not limited by a power supply, can adapt to wider application scenes, and the invention can prolong the service life of the passive or low-power-consumption equipment.

Description

technical field [0001] The present application relates to a communication method, device, system and electronic equipment, belonging to the technical field of computers. Background technique [0002] At present, passive or low-power devices have been applied in many scenarios in the retail field, such as Bluetooth tags or some low-power MCUs, etc. These devices require power supply to perform corresponding data processing. For this reason, these devices are generally equipped with batteries or still need an external power supply, and the power of the battery is limited, so that the service life of these devices is also limited. If the form of an external power supply is used, the range of use will inevitably be limited. limit. Contents of the invention [0003] Embodiments of the present invention provide a communication method, device, system and electronic equipment, so that passive or low power consumption equipment can reduce the dependence on power supply. [0004] ...
