具体而言，参照图5所示，可以首先执行步骤S510，处理器140发送握手信号，在协议模块122接收到处理器140发送来的握手信号时，即表示充电接口已经连接在待充电设备，此时，可以执行步骤S520，可以将协议模块122已调整为空闲状态(IDLE状态)准备数据传输，同时，将握手信号发送给适配器110，适配器110接收到握手信号，后发出协议发送指令，在协议模块122接收到协议发送指令后，可以执行步骤S530，协议模块122跳转至数据接收状态(RECV_DATA状态)，然后适配器110发送协议内容，其中该协议内容可以是需要接收的数据，即需要接收的数据包括上述属性信息中的一种或多种，协议内容中还可以为需要接收数据的位数，例如，接收8位数据、9位数据等，此时协议模块在接收属性信息是包括接收数据计数功能。Specifically, referring to FIG. 5 , step S510 may be executed first, and theprocessor 140 sends a handshake signal. When theprotocol module 122 receives the handshake signal sent by theprocessor 140, it means that the charging interface has been connected to the device to be charged. At this time, step S520 can be performed, and theprotocol module 122 can be adjusted to an idle state (IDLE state) to prepare for data transmission, and at the same time, the handshake signal is sent to theadapter 110, and theadapter 110 receives the handshake signal, and then sends out a protocol sending instruction, at After theprotocol module 122 receives the protocol sending instruction, it can perform step S530, theprotocol module 122 jumps to the data receiving state (RECV_DATA state), and then theadapter 110 sends the protocol content, wherein the protocol content can be the data to be received, that is, the data needs to be received The data includes one or more of the above attribute information, and the content of the protocol can also be the number of bits that need to receive data, for example, to receive 8-bit data, 9-bit data, etc. At this time, when the protocol module receives attribute information, it includes receiving Data count function.

At this time, the attribute information includes all attribute information required in the protocol content, for example, the current of thebattery 160, the temperature of thebattery 160, and the like. After theprotocol module 122 receives the attribute information, step S360 may be executed, theprotocol module 122 jumps to the data sending state (SEND_DATA state), then sends the attribute information to theadapter 110, and then jumps to the idle state (IDLE state).

在本示例实施方式中，在上述协议模块122没有接收到处理器140发送的属性信息，或者接收的属性信息不完整时，即数据接收出错时，可以执行步骤S540，将所述协议模块122跳转至关闭状态(DISABLE状态)，其中接收的属性信息不完整时，可以例如，协议内容中需要获取的数据包括电池160的电压、电流以及温度，但是接收到的属性信息只包括电池160的电压以及电流，没有温度信息，此时判定接收到的属性信息不完整。再例如，协议内容中需要接收的数据为8位数据，但是，协议模块122接收到的上述属性信息不够8位数据，例如6位数据、7位数据等，则可以执行步骤S540，将协议模块122跳转至关闭状态(DISABLE状态)。In this exemplary embodiment, when the above-mentionedprotocol module 122 does not receive the attribute information sent by theprocessor 140, or the received attribute information is incomplete, that is, when an error occurs in data reception, step S540 may be executed to make theprotocol module 122 jump Turn to the OFF state (DISABLE state), where the received attribute information is incomplete, for example, the data to be acquired in the protocol content includes the voltage, current and temperature of thebattery 160, but the received attribute information only includes the voltage of thebattery 160 As well as current, there is no temperature information, and it is determined that the received attribute information is incomplete at this time. For another example, the data to be received in the protocol content is 8-bit data, but the above-mentioned attribute information received by theprotocol module 122 is not enough for 8-bit data, such as 6-bit data, 7-bit data, etc. 122 Jumps to the OFF state (DISABLE state).
