Definitions

  • the present application relates to the field of aerosol provision technology, particularly to a communication method for an aerosol provision system and an aerosol provision system.
  • An aerosol provision system refers to a system that contains aerosol-generating materials inside and heats the aerosol-generating materials to generate an aerosol for the user to puff.
  • an aerosol provision system generally comprises a device end with a controller and a power source, as well as a cartridge with a heating element.
  • the device end needs to communicate with the cartridge to obtain more information about the cartridge, such as the cartridge model, the consumption of the atomization matrix in the cartridge, the real-time temperature/resistance value of the heating element, etc.
  • the device end also needs to send an electric power supply signal to the heating element for heating control.
  • the heating control and communication are carried out independently, resulting in overly frequent and inefficient signal transmission between the device and the cartridge.
  • a communication method for an aerosol provision system and an aerosol provision system so that the device and the cartridge can achieve efficient communication and heating control through the same data frame transmitted by the same electrode.
  • a communication method for an aerosol provision system comprises: a device of the system encapsulates and sends a first data frame to an electrode of the system based on a serial communication protocol, the first data frame comprises supplementary data and main data carrying communication data; both the supplementary data and the main data are logic level signals and the distribution of the logic level signals is determined based on the magnitude of the target electric power provided to a cartridge of the system; the electrode transmits the first data frame to a heating element and a control unit of the cartridge; the heating element performs heating control according to the high-low level signal in the logic level signal; and the control unit decapsulates the first data frame according to the serial communication protocol and parses the main data to obtain the communication data carried by the first data frame.
  • the data frame transmitted between the device and the cartridge is set as main data in the form of logic level signals and supplementary data in the form of logic level signals.
  • the main data in the data frame is used for communication, and the logic level signals of the main data and the supplementary data are used for heating control. Since the supplementary data has nothing to do with communication, the supplementary data can be adjusted to adjust the electric power.
  • communication and electric power control can be carried out between the device and the cartridge through one data frame. Since it is one data frame, it can be transmitted through only one electrode, so efficient and low-cost communication and heating control are achieved.
  • the device encapsulates the first data frame based on the serial communication protocol may comprise: the device determines the logic level signal distribution of the main data according to the communication data to be carried, and determines the logic level signal distribution of the supplementary data according to the target electric power, such that the ratio of total high level signals in the main data and the supplementary data corresponds to the target electric power.
  • the device has a maximum electric power provided to the heating element.
  • the target electric power is a ratio of the target electric power to the maximum electric power.
  • the target electric power determines the logic level signal distribution of the supplementary data, such that the ratio of total high level signals in the main data and the supplementary data corresponds to the target electric power, which comprises: determining the data length of the supplementary data and the data length of the high-level signal of the supplementary data according to the data length of the main data and the data length of the high-level signal of the main data, making the ratio of the total data length of the high-level signal in the main data and the supplementary data to the total data length of the main data and the supplementary data corresponds to the target electric power.
  • the main data comprises at least one main data segment
  • the supplementary data comprises at least one supplementary data segment
  • the main data segment is adjacent to the supplementary data segment.
  • the main data segments and the supplementary data segments are adjacently distributed and can be successively received by the cartridge on the time axis. This enables the supplementary adjustment of the electric power to be carried out dispersedly throughout the heating process. It avoids the situation where, due to the continuous distribution of the main data segments, the electric power cannot be supplemented and adjusted for a long period during the heating process, resulting in a large difference in the magnitude of the electric power in different periods and making it uneven.
  • the number of the main data segments is the same as the number of the supplementary data segments.
  • each of the main data segments comprises at least one byte, and/or each of the supplementary data segments comprises at least one byte.
  • the data length of each of the main data segments is the same as the data length of each of the supplementary data segments located thereafter. In this way, the uniform distribution of the electric power throughout the heating process can be achieved, and it is convenient for the cartridge to identify the main data segments and the supplementary data segments.
  • the high and low level signals in each of the supplementary data segments are evenly distributed. Based on this, the uniform distribution of the electric power can be improved, and a large difference in the electric power between the front and rear periods can be avoided.
  • the main data comprises a frame header, data length indication information, valid data and a check code.
  • the control unit decapsulates the first data frame according to the serial communication protocol and parses the valid data to obtain the communication data.
  • the control unit parses the main data and the supplementary data according to the serial communication protocol to obtain the target electric power carried by the main data and the supplementary data according to the logical signal distribution. Based on this, in addition to parsing the main data to obtain the communication data, the cartridge end can also parse the entire data frame to obtain the target electric power information. Thus, the device end can transmit two kinds of communication information to the cartridge through one data frame, improving the communication efficiency.
  • the method further comprises: the control unit responds to the communication data, based on the serial communication protocol, the control unit encapsulates the response information to generate a second data frame, and sends the second data frame to the device through the electrode; and the device decapsulates the second data frame based on the serial communication protocol and parses the second data frame to obtain the response information.
  • the logical level signal may be a TTL level signal.
  • the serial communication protocol may be a LIART communication protocol.

  • the main data in the data frame is used for communication, and the high-low level signals of the main data and the supplementary data are used for heating control. Since the supplementary data has nothing to do with communication, the supplementary data can be adjusted to adjust the electric power.
  • efficient and accurate communication and electric power control are achieved between the device and the cartridge through one data frame.
